说明书全文 | The invention relates to an electrical connection device, preferably a mini-coaxial connection device, as well as a connector or a counter-connector, preferably a mini-connector or a mini counter-connector, for a cable, in particular a coaxial cable. Furthermore, the invention relates to a method of assembling an electrical cable as well as an assembled electrical coaxial cable, preferably an assembled electrical copper and/or aluminium coaxial cable. Furthermore, the invention relates to a device, a module, an appliance, an apparatus, an installation or a system, in particular for the automotive industry. In the electrical domain (electronics, electrical engineering, electrics, electrical energy technology etc.) a large number of electrical connection means and devices, bushing and/or pin connectors etc. - in the following referred to as (electrical) (counter-)connectors or (counter-) connection devices - are known which serve to transfer electrical currents, voltages, signals and/or data with a large bandwidth of currents, voltages, frequencies and/or data rates. In the low, medium or high voltage and/or current range, and in particular in the automotive industry, such connectors must guarantee the transfer of electrical power, signals and/or data in the short term and/or in the long term in warm or hot, contaminated, humid and/or chemically aggressive environments. Due to a large bandwidth of applications, a large number of specifically configured connectors are known. Such connectors and their housings can be assembled at an electrical cable, a line, a cable harness and/or an electrical means or device, such as e.g. at/in a housing or on/at a circuit board of an electrical, electro-optical or, respectively, electronic component or this type of unit; in the latter case, one often speaks of a (counter-)connector device. If a connector is only located at a line, a cable or a cable harness, one mostly speaks of a (flying) (plug) connector or a plug or a coupling, and if it is located at/in an electrical, electronic or electro-optical component, one mostly speaks of a (built-in) connector, such as a (built-in) plug or a (built-in) bushing. Furthermore, a connector on this type of device is often also referred to as a plug receiver or a header, the connector often having a support collar which is intended to guarantee a robust connection. Electrical connectors must guarantee a perfect transmission of electrical signals (voltage) and/or electrical power, connectors corresponding to one another (connectors and counter-connectors) mostly having fastening or locking means for long-term, but generally detachable, fastening or locking of the connector in/at the counter-connector. Furthermore, corresponding electrical contact elements, such as e.g. an actual electrical contact means and/or an actual electrical shielding contact means, i.e. for example an electrical connection device of the connector, must be securely held in the latter. Since the housings of the connectors are mostly subject to a particular standardisation, such as e.g. the FAKRA standard, the most important dimensions of the housings have the same dimensions with different manufacturers. Efforts are constantly being made to improve and to reduce electrical connectors and/or to make them less expensive. The on-going miniaturisation does not stop either at the cross-sections of the cables and/or the connection devices involved. Efforts are thus being made e.g. to reduce the dimensions of coaxial cables and the connection devices of the latter in order to reduce installation space, to be able to make the best possible use of a line cross-section with a given maximum current load capacity, and to save resources, in particular copper. Furthermore, miniaturisation results in a desirable saving in weight. Of course, this relates not only to coaxial cables, but also to other cables and the connection devices of the latter. It is an object of the invention to specify an improved electrical connection device, preferably an improved mini-coaxial connection device, and an improved connector or counter-connector, preferably a mini-connector or mini-counter-connector, for a cable, in particular a copper and/or aluminium cable. In this connection the connection device and the connector or counter-connector must be small, be of simple construction and/or be easy to handle, its production and also its subsequent assembly needing to be inexpensive. Furthermore, it is an object of the invention to make available a method of assembling an electrical cable, preferably a copper and/or aluminium coaxial cable. In this connection it should be possible to implement the method efficiently with flexible process management, e.g. optionally also at a customer's premises. The object of the invention is achieved by means of an electrical connection device, preferably a mini-coaxial connection device, for a cable, in particular a copper and/or an aluminium cable; by means of a connector or a counter-connector, preferably a mini-connector or a mini-counter-connector, for a cable, in particular a coaxial cable; using a method of assembling an electrical cable, preferably a copper and/or an aluminium coaxial cable; by means of an assembled electrical coaxial cable, preferably an assembled electrical copper and/or aluminium coaxial cable; as well as a device, a module, an appliance, an apparatus, an installation or a system; preferably for the automotive industry, according to the independent claims. - Advantageous further developments, additional features and/or advantages of the invention emerge from the dependent claims and the following description. The connection device according to the invention comprises at least two separate parts, a first (single) part being in the form of a ferrule that can be provided on/at a cable, and a second (individual) part being in the form of a (first) electrical contact means that can be provided on/at the cable, and the ferrule preferably being able to be or being connected securely, at least mechanically, to a second electrical conductor of the cable, and the contact means preferably being able to be or being securely connected electromechanically to a first electrical conductor of the cable. The contact means can be in the form of a pin, male, tab, female, jack contact means etc. An electrical counter-connection device is formed in the same way and in part complementarily (e.g. a pin, male, tab contact means as opposed to a female or jack contact means), the terms of connection device and counter-connection device being able to be used synonymously. This can also be applied to a connector and a counter-connector (see also below). Depending on a configuration of a connector housing, one can dispense with a contact cavity insert or adapter when assembling the connection device in the connector housing, except for one for a seal. In embodiments substantially an entire longitudinal extension of the ferrule in an axial direction of the connection device can be or is provided on/at the second conductor, i.e. in a fitted state of the ferrule on/at the cable there is no axial overlapping of the ferrule with an electrical insulation, in particular an outer insulation, of the cable. In this way, a diameter of the connection device can be kept small. The ferrule can be configured such that in its fitted state the ferrule has a constant internal diameter in the axial direction. Furthermore, the ferrule can be constituted as a single fittable mounting section. Preferably, this ferrule is made in the form of a plastically deformable, in particular bendable or crimpable, open or closed ferrule, e.g. a sleeve. On one long side, the ferrule can have a single mounting means, in particular a mounting flank, i.e. on one long side, the ferrule does not have two mounting means, such as e.g. crimping flanks or crimping lugs. Accordingly, on each of its two long sides the ferrule can comprise a mounting flank, i.e. the ferrule preferably has just one single mounting function, namely to fix the second conductor, it furthermore being able to form a basis for the fitting of a second contact means (see below). The ferrule does not clamp together two entities in the axial direction. Therefore, the ferrule does not have a transitional section e.g. between two mounting sections. Preferably, the ferrule is configured such that, in the fitted state on/at the cable, it forms a single sleeve, and not a double sleeve or similar, on/at the cable, except for a gap or reciprocal circumferential engagement in the axial arrangement. The connection device can have a third separate part, the third part being in the form of a second contact means that can be provided on/at the cable, and the second contact means preferably being able to be or being connected electrically to a second conductor of the cable. Furthermore, the connection device can be configured such that an outer conductor of the cable and/or the second contact means can be or is provided above, in the sense of outside of, the ferrule, and not beneath, in the sense of within, the ferrule. In other words, the three parts of a single connection device - i.e. the ferrule, the first contact means and the second contact means - are ideally all three separate from one another, at least chronologically prior to being mounted, i.e. they are designed to be separated from one another individually and mechanically. It is preferred if the second contact means can be or is mechanically connected securely to the second conductor, and this can take place above the ferrule, in particular in the radial direction of the connection device. Alternatively, the electrical contact can also take place by means of an electrically conductive ferrule, i.e. the ferrule can be in the form of an electrically conductive or an electrically non-conductive ferrule, the ferrule preferably being able to be shaped, in particular being able to be punched or punch pressed, from a metal sheet. In a state chronologically prior to its fitting on/at the cable, the ferrule can be made to be open and/or gaping in the circumferential direction. Furthermore, in the state chronologically prior to its fitting on/at the cable, the ferrule can be made to be at least partially closed, i.e. also fully closed, in the circumferential direction. On its two face sides in the axial direction, the ferrule is preferably made to be open. In the state chronologically prior to its fitting on/at the cable, the ferrule can have a smooth and/or structured outer and/or inner surface. Structuring of the ferrule can take place during the plastic deformation, in particular a locking means, a groove and/or a rib on/in the ferrule being able to be or being established. In embodiments the second contact means above the ferrule can be mounted or is mounted sitting directly or indirectly on the ferrule. Furthermore, when fitting the connection device the second contact means can be lockable to or locked to the ferrule. For this purpose the second contact means and the ferrule have corresponding locking means which can lock with one another when the connection device is assembled. In this connection the ferrule can preferably block the second contact means on the cable at least in a plugging direction of the second contact means, i.e. entrain it in the direction of a counter-plugging direction of the ferrule; or vice versa, i.e. the second contact means blocks the ferrule at the cable in the counter-plugging direction of the ferrule. In addition or alternatively, this can also be established conversely in a kinematic manner. Locking means that relate to one another can be made in the form of a locking projection, a locking recess or a locking shoulder, and as a locking recess, a locking projection or a locking shoulder. In embodiments a locking of the ferrule with the second contact means is effective in at least one axial direction. The locking of the ferrule with the second contact means may be constituted by a locking means of the ferrule and a locking means of the second contact means. The locking means of the ferrule may comprise at least one locking projection, one locking shoulder, one locking edge or one locking recess. The locking means of the second contact means may comprise at least one locking recess, one locking shoulder, one locking projection or one locking lug. The ferrule may comprise on/at its inner side and/or on/at its outer side a blocking means. The second contact means may comprise, in particular in its mounting section, at least one blocking means. The second contact means may comprise as a blocking means an anti-slip means for the cable. In embodiments the ferrule (chronologically prior to its fitting) can have a substantially U-shaped or V-shaped cross-section in a radial plane of the connection device and preferably be in the form of a mainly or substantially single material layer. Furthermore, the ferrule can have two mounting means substantially located opposite one another, the mounting means preferably being in the form of mounting flanks or crimping flanks, i.e. the ferrule can be referred to as an optionally crimpable pressed ferrule. Moreover, the optionally crimpable ferrule can be referred to as or be in the form of a pressure sleeve, a clamping ring, an annular mounting or a braid end sleeve, this type of ferrule being able to be made to be open, partially closed or substantially fully closed. The two mounting means preferably meet in a circumferential direction of the connection device and are preferably securely connected to one another (see also below). In embodiments the second contact means can have two mounting means located substantially opposite one another, wherein the optionally only two mounting means preferably being in the form of mounting wings or crimping wings (comprising one lug or more lugs). Furthermore, the two mounting means can be fastened to a transitional section or a contact section of the second contact means. The two mounting means preferably meet in a circumferential direction of the connection device and are preferably securely connected to one another (see also below). Furthermore, the first contact means comprises, in addition to a contact section (e.g. pin, male, tab, female, jack contact section etc.) and an optionally established transitional section, preferably two mounting means lying substantially opposite one another in the radial direction. In this connection, the optionally only two mounting means are preferably once again in the form of mounting wings or crimping wings (comprising one lug or more lugs). The two mounting means preferably meet in a circumferential direction of the connection device and are particularly connected securely to one another (see also below). In embodiments the mounting means of the ferrule can have two circumferential edge sections configured to be substantially complementary or substantially form-locking. Furthermore, embodiments of the mounting means of the second contact means can have two circumferential edge sections configured to be substantially complementary or substantially form-locking. In this connection, and optionally also in other embodiments of the ferrule and/or of the second contact means, the two mounting means relating to one another are disposed substantially opposite one another in the circumferential direction and/or in the radial direction of the connection device (chronologically prior to and/or after assembly). Circumferential edge sections that relate to one another can form a type of toothing here in a respective mounting position, a projection of a circumferential edge section engaging in a recess of the respective other circumferential edge section in the circumferential direction. A space, a slot or play can be established here between the edges of the respective circumferential edge sections. Preferably, the second contact means is in part made in the form of a partially closed (e.g. first contact means in the form of a jack contact means, but a pin or tab contact means etc. may also be used) or substantially closed (e.g. first contact means in the form of a pin or tab contact means, but a jack contact means may also be used) sleeve (contact section, shielding contact section), and in part as an open (mounting means open, e.g. substantially straight crimping wings/lugs) or, respectively, partially open (mounting means bent or pre-rolled) sleeve (mounting section, e.g. bending or crimping section). In the mounting section the second contact means can have at least one blocking means, by means of which the second contact means can be or is additionally held on/at the cable. In this connection, the blocking means is preferably located towards the inside in the mounting section. In a mounted state of the second contact means, the blocking means, e.g. in the form of an inner projection, nose, rib, piercing means etc., penetrates, deforming elastically or plastically, into the outer insulation of the cable. In this connection, the blocking means squashes the outer insulation or actually penetrates into it, e.g. slicing or bursting open the outer insulation. Within the second contact means, there is preferably a dielectric or electrical insulation in which the first contact means can be mounted and optionally locked in place or is mounted and optionally locked in place. The dielectric has, in addition to its electrically insulating function, the further function of centring the first contact means. In a pin, male, tab contact section, this preferably only takes place at the rear, i.e. away from a free end section and a middle section of the pin, male, tab contact section. In a bushing contact section, this also preferably takes place at the rear (in the above sense), and furthermore preferably in a middle section, in/at a free longitudinal end section and/or at a free end of the bushing contact section. In embodiments the pin, male, tab contact section extends freely within the second contact means, extending towards its mating face. In this connection, a free end of the pin, male, tab contact section can be set up to be able to move substantially radially in the second contact means, depending on the rigidity of its material. Furthermore, in embodiments the bushing contact section extends within the dielectric and is guided radially within the latter. Preferably, radial movability of the bushing contact section is limited at least to a small degree. In this connection, radial freedom of movement of the bushing contact section is preferably less than the radial freedom of movement of the pin, male, tab contact section. For access of the first contact means to and/or into the second contact means the dielectric for a jack contact means has a through-hole preferably with an insertion aid, such as e.g. an insertion incline. Moreover, the dielectric can preferably be able to be blocked or is blocked in the second contact means, at least in the plugging direction of the dielectric into the second contact means, by means of locking means corresponding to one another (locking recess, projection, shoulder and locking projection, recess, shoulder) of the dielectric and of the second contact means. In the mounted state of the second contact means on/at the cable, the dielectric and the ferrule are preferably arranged in a row and preferably have substantially the same external diameters, preferably apart from a double layer thickness of the outer conductor of the cable. In embodiments the ferrule, the first contact means and/or the second contact means is/are made in one piece, made of the same piece of material or formed integrally; a structure made of a number of pieces, optionally linked together, i.e. optionally a one-piece structure, can however be used. One-piece is intended to mean that individual parts (if these exist) of a respective component can not be separated simply by hand or by means of a tool, and possibly not without damaging its individual parts, as is the case e.g. with an assembled cable. Physical cohesion is preferably achieved by means of force and/or form closure. In a component made of one piece of material its individual parts (if these exist) are fixed to one another with material locking and can preferably not be separated without damaging one of its individual parts. Physical cohesion can furthermore be generated by means of force and/or form closure. In an integral component, which is respectively preferred for the three components of the connection device, there is only one single component which can virtually only be separated by destroying the latter. This component is produced from a single piece which, on its part, can be integral or monolithic. - A counter-example of a one-piece, materially one-piece or integral component are the three separate components of a connection device that has not been assembled, taken together. The connector according to the invention has a connection device according to the invention and/or the counter-connector according to the invention has a counter-connection device as a connection device according to the invention. This type of connector or counter-connector can be designed for a single cable or a plurality of cables, in particular an even number of cables, such as e.g. two, four or six. Furthermore, ideally a single connector or counter-connector as a single sold part preferably does not include a cable. It is of course possible to supply a single cable or a plurality of cables with the connector or counter-connector for sale. This is to be adapted appropriately depending on the circumference of the reels (carrier strips with respective parts of the connection device). In the method according to the invention, in a first step (exemplary illustration in In the assembling method, in the first step the cable can be inserted into the ferrule with a section liberated from outer insulation of the cable, or vice versa (partial step I.1, Furthermore, in the first step of the assembling method the ferrule can be plastically deformed, preferably bent or crimped, when being fitted onto the outer conductor (second conductor) (partial step I.2, a transition from Moreover, in the first step of the assembling method an exposed end section of the outer conductor (second conductor) can be placed around the outside of the ferrule (partial step I.3, a transition from In the second step the first contact means (pin, male, tab, female, jack contact means etc.) is preferably separated from a carrier strip and is subsequently fastened, in particular crimped, on/at the inner conductor (first conductor) of the cable (step II, a transition from In the assembling method, in a preparation step at least one mounting wing/lug of the second contact means, preferably on a carrier strip for second contact means, can be pre-bent or pre-rolled (partial step III.1a, a transition from When equipping the second contact means with the first sub-assembly comprising a cable, a ferrule and a first contact means, at least one mounting wing/lug of the second contact means can be open (a transition from A second sub-assembly that is produced comprising a cable, a ferrule, a first contact means and a second contact means can subsequently be separated from the carrier strip (partial step III.2, a transition from The assembled coaxial cable according to the invention comprises an electrical coaxial cable with an electrical connection device at least partially connected to the latter. In this connection, a ferrule of the connection device is mechanically securely connected to an electrical outer conductor of the coaxial cable, a first electrical contact means of the connection device is securely connected electromechanically to an electrical inner conductor of the coaxial cable, and a second electrical contact means of the connection device can be connected electrically or is connected electrically to the outer conductor. The ferrule, the first electrical contact means and the second electrical contact means are preferably formed as separate parts. In this connection, the ferrule sits preferably exclusively on the outer conductor. A free long end section of the outer conductor can be passed over or around the outside of the ferrule; however, it is also possible to omit this feature and only provide the ferrule on/at the long end section of the outer conductor that is bound in this way. In such a case the ferrule must be electrically conductive if otherwise no electrical contact has been established between the outer conductor and the second contact means. Furthermore, the first electrical contact means can be in the form of a pin, male, tab, female, jack contact means etc. In embodiments, during the assembly of the coaxial cable, the second contact means can have at least one open or pre-bent mounting means, in particular an open or pre-rolled crimping wing/lug. Furthermore, the second contact means with the at least one open or pre-bent mounting means can be plugged or be able to be plugged over the ferrule. In a second contact means pushed over the ferrule, the at least one open or pre-bent mounting means can be brought substantially into its mounting position in one partial step. In a mounted state of the second contact means on/at the coaxial cable, the second contact means can engage tightly on/at the outer conductor, on/at the ferrule and/or on/at the outer insulation, i.e. in the mounted state the mounting means fastens or the preferably two individual mounting means of the second contact means located opposite one another fasten the second contact means both on/above the ferrule and on/at the cable. In embodiments the assembled coaxial cable can be in the form of a pre-assembled coaxial cable. Furthermore, a second contact means separate from the coaxial cable, the first contact means and/or the ferrule can be associated with the pre-assembled coaxial cable. In embodiments the connection device can be in the form of a counter-connection device. Furthermore, the connection device can be in the form of a connection device according to the invention. Moreover, the assembled coaxial cable can be produced by an assembling method according to the invention. The device according to the invention, the module according to the invention, the appliance according to the invention, the apparatus according to the invention, the installation according to the invention or the system according to the invention has an electrical connection device according to the invention, an electrical connector according to the invention and/or an assembled electrical coaxial cable according to the invention. Furthermore, the device according to the invention, the module according to the invention, the appliance according to the invention, the apparatus according to the invention, the installation according to the invention or the system according to the invention can additionally or alternatively have an electrical cable which is produced by an assembly method according to the invention. It is advantageous, for example, that installation space for a connection device, a connector housing, a connector and thus for a connection, as well as for a cable can be reduced. In this way smaller line cross-sections can be used, which saves on costs and/or resources. Furthermore, there is a weight reduction in comparison to conventional cables. Moreover, it is made possible to encode or polarise the second contact means and to avoid superior strands of a shielding braid of the coaxial cable chronologically prior to (pre-assembled) and/or after (completely assembled) the mounting of the second contact means, in particular for coaxial cables by means of a pre-bent or pre-rolled mounting means of the second contact means. In the following, the invention will be explained in more detail by means of exemplary embodiments with reference to the attached detailed drawing that are not true to scale. Elements, component parts or components which have an identical, univocal or analogous design and/or function are provided with the same reference numbers in the description of the figures, the list of reference signs and the claims, and are identified with the same reference numbers in the figures (Fig.) of the drawing. Possible alternatives that are not explained in the description, are not shown and/or not completed in the drawing, static and/or kinematic inversions, combinations etc. relating to the explained exemplary embodiments of the invention or individual assemblies, parts or sections of the latter can, furthermore, be taken from the list of reference signs. All of the features explained, including those of the list of reference signs, can be used not only in the specified combination or the specified combinations, but also in a different combination or different combinations or on their own. In particular, it is possible to replace a feature or a plurality of features in the description of the invention and/or the description of the figures by means of the reference numbers and the features assigned to the latter in the description of the invention, the description of the figures and/or the list of reference signs. Furthermore, in this way a feature, or a plurality of the features in the claims can be interpreted, specified in more detail and/or substituted. - The figures, which are given only by way of example, show as follows:
The invention ( Furthermore, in the following the designations connector 1 and counter-connector 1, connection device 100 and counter-connection device 100, pin/stud/tab contact means 300 and female or jack contact means 300, and pin/male/tab contact section 330 and female or jack contact section 330 are to be interpreted synonymously, i.e. can each optionally be interchanged with one another. - Furthermore, in the following the invention will be explained in more detail by means of a coaxial cable 60, in particular a copper 60 and/or an aluminium coaxial cable 60, the invention not being restricted to this type of cable 60, but once again being of a more basic nature, and so the invention can also be applied to other cables 60, lines 60, cable harnesses 60 etc. In the following, with reference to In a (first) partial step I.1 illustrated in In this connection, as is preferred, the rear section of this exposed outer conductor 640 is inserted into a respective ferrule 200 located on a carrier strip 260 (dashed line in In this connection, before being fitted, the preferably plastically deformable and in particular integral ferrule 200 is open or gaping in a circumferential direction Um around the connection device 100 or, respectively, the ferrule 200 and comprises two mounting means 210, 220 which are in the form of mounting flanks 210, 220, in particular crimping flanks 210, 220. A respective mounting flank 210, 220 has a circumferential edge section 213, 224. In this connection, the two circumferential edge sections 213, 224 that relate to one another are preferably made to substantially complement one another or to be substantially form-locking so that a gap between the mounting flanks 210, 220 of the fitted ferrule 200 in the axial direction Ax of the connection device 100 and the ferrule 200 is made to be substantially impermeable to light ( Furthermore, during the plastic deformation of substantially the entire ferrule 200, at least one locking means 240, in particular a locking projection 240 (see In a (third) partial step I.3 illustrated in In a (fourth) partial step I.4 illustrated in The elongated and in particular integrally formed first contact means 300 has on a rear end section a mounting section 310, in particular a crimping section 310, with two mounting means 311, 312 located opposite one another, which are preferably made in the form of mounting wings 311, 312 (comprising one lug or more lugs), in particular crimping wings 311, 312 (comprising one lug or more lugs). In this connection, preferably only the mounting section 310 is at least partially plastically deformable, wherein before being mounted, the mounting wings 311, 312 are open or gaping in a circumferential direction Um. Preferably, only two (main) mounting lugs are provided. Furthermore, the first contact means 300 has on a front end section a contact section 330 which can be in the form e.g. of a pin 330, male 330, tab, female, jack contact section 330 etc. Moreover, the first contact means 300 can have a transitional section 320 between the mounting section 310 and the contact section 330. Furthermore, the first contact means 300 can have a locking means 340, preferably in the transitional section 320, in particular a locking projection, a locking recess or a locking shoulder, for blocking the first contact means 300 in a dielectric 500 (see also below). In the second step II, the first contact means 300 is first of all separated from a carrier strip for first contact means 300. Subsequently, the mounting section 310 is moved towards an exposed longitudinal end section of the inner conductor 630, and the exposed longitudinal end section of the inner conductor 630 and the mounting section 310 are moved towards one another, the longitudinal end section of the inner conductor 630 taking position in a bottom of the mounting section 310. Subsequently, the mounting section 310 is crimped to the inner conductor 630. This can also take place in reverse, i.e. crimping of the mounting section 310 to the inner conductor 630, the first contact means 300 still being located on the carrier strip. A (pre-)assembled coaxial cable 6 produced in this way is then only separated subsequently from the carrier strip. - Furthermore, The third step III of the assembling method relates to the mounting of a second electrical contact means 400 with up to two to four or more partial steps (III.1a to III.3). In this connection the second contact means 400 can have different configurations, depending on whether it is to be mounted on a cable 6 (pre-)assembled with a pin contact means 300 etc. or a jack contact means 300. Irrespective of the differences between such second contact means 400, the three alternative third steps III are substantially the same. The elongate and in particular integrally formed second contact means 400 is preferably in the form of a crimping sleeve 400, an impedance contact means 400, a shielding contact means 400 etc. In this connection, the second contact means 400 has on a rear end section a mounting section 410, in particular a crimping section 410, with two mounting means 411, 412 lying opposite one another and which are preferably in the form of mounting wings 411, 412 (comprising one lug or more lugs), in particular crimping wings 411, 412 (comprising one lug or more lugs). In this connection the mounting wings 411, 412 may be open, gaping, bent and/or pre-rolled. Furthermore, within the framework of the third step III, the mounting wings 411, 412 can be bent or pre-rolled (see also below). Preferably, only the mounting section 410 of the second contact means 400 is at least partially plastically deformable. In this connection, preferably only two (main) mounting lugs are provided. Each respective mounting wing 411, 412 preferably has a circumferential edge section 413, 414. In this connection, the two circumferential edge sections 413, 414 relating to one another are preferably made to be substantially complementary or to be substantially form-locked to one another so that a gap between the mounting wings 411, 412 of the mounted second contact means 400 in the axial direction Ax of the second contact means 400 can be made to be substantially impermeable to light ( Furthermore, the second contact means 400 has on a front end section a contact section 430 which is preferably in the form of a shielding contact section 430. A different contact section 430 can of course be used. Moreover, the second contact means 300 can have a transitional section 420 between the mounting section 410 and the contact section 430 which is preferably in the form of a sleeve. Furthermore, the second contact means 400 preferably has a locking means 440, in particular a locking projection, a locking recess 400 or a locking shoulder 440, in particular in its mounting section 410 or, respectively, in at least one mounting wing 411, 412 for blocking the ferrule 200. Furthermore, within the preferably partially sleeve-shaped second contact means 400, a dielectric 500 or electrical insulation 500 can be provided or established. The dielectric 500 is used for electrical insulation of the first contact means 300 with respect to the second contact means 400 and, furthermore, is preferably used for the mounting and/or centring of the first contact means 300 in the second contact means 400, and thus in the connection device 100. The dielectric 500 is preferably formed in a number of pieces, in one piece, from one material piece or integrally. Furthermore, the dielectric 500 can be locked in the second contact means 400, or at least in a direction S of plugging the dielectric 500 into the second contact means 400, can be blocked in the second contact means 400. - In the following, the three alternative third steps II will be explained in brief. In the first alternative assembly ( In a subsequent (third) partial step III.3, the mounting section 410 of the second contact means 400 is fully closed, preferably crimped, the ferrule 200 locking with the second contact means 400, in particular with its mounting section 410, on at least two edges lying opposite one another (locking means 240, 440, see also In the second alternative assembly ( In a subsequent (third) partial step III.3, the substantially straight mounting section 410 of the second contact means 400 is fully closed, preferably crimped, the ferrule 200 once again locking with the second contact means 400, in particular with its mounting section 410, on at least two edges located opposite one another (locking means 240, 440, see also In the third alternative assembly ( Furthermore, in the (first) partial step III.1b the second contact means 400 with the prepared mounting wings 411, 412 from partial step III.1a and a (pre-)assembled cable 6 obtained from the second step or a sub-assembly 20 (here according to In a subsequent (third) partial step III.3 the mounting section 410 of the second contact means 400 is fully closed, preferably crimped, the ferrule 200 locking with the second contact means 400, in particular with its mounting section 410, on at least two edges located opposite one another (locking means 240, 440) ( This closed contact section 430 extends from a mating face of the second contact means 400 to the rear in the axial direction Ax. In this connection, the contact section 430 preferably extends at least so far to the rear such that in a plugged state of a connection device 100 to a counter-connection device 100, sections of the respective contact sections 330, 330 of respective first contact means 300, 300 that are plugged into one another are in particular fully shielded electromagnetically (see In Furthermore, the second contact means 400 has in particular in its mounting section 410 at least one blocking means 450 by means of which the second contact means 400 can be blocked on the cable 60. In this connection, the mounting section 410 furthermore fixes the turned over end section 642 of the outer conductor 640 on the ferrule 200 and the ferrule 200 on the outer conductor 640. This type of blocking means 450 can be in the form of an inner projection 450, a nose 450, a rib, a piercing means 450 etc. Depending on the mounting method and also the consistency of the outer insulation 620, a recess or passage recess can also be used as a blocking means 450 in the mounting section 410. Preferably, the second contact means 400 has, in particular in its mounting section 410, a plurality of blocking means 450, four blocking means 450 being shown in In another embodiment, shown in Furthermore, the ferrule 200 may also comprise blocking means 215. Such a blocking means 215 may be formed as an anti-slip means 415, a corrugation, a ribbing, a rippling, as grooves 215 (cf. The blocking means 415 of the second contact means 400 and the blocking means 215 of the ferrule 200 may interact during mounting the second contact means 400 on/at the cable 60. Here, a protrusion of the blocking means 415 of the second contact means 400 may interact with a recess of the blocking means 215 of the ferrule 200, and/or a protrusion of the blocking means 415 of the second contact means 400 may interact with a protrusion of the blocking means 215 of the ferrule 200. Herewith a secure hold of the second contact means 400 on/at the turned over end section 642, the outer conductor 640 and/or the cable 60 is realisable. This feature is also applicable to the above mentioned embodiments. On the contrary to the locking of the ferrule 200 with the second contact means 400 shown in In particular during mounting (crimping) the second contact means 400 on/at the cable 60, the locking lugs 440 may be bent into the inner side of the second contact means 400. This may also be done before the mounting of the second contact means 400. When the second contact means 400 is mounted on/at the cable 60, the locking shoulder at the locking lug 440 (locking means 440, locking projection 440) is blocked at the locking means 240 of the ferrule 200. Such a locking means 240 of the ferrule 200 may be formed as locking recess, a locking shoulder 240, a locking edge 240 etc. (cf. above). Here, the locking of the ferrule 200 with the second contact means 400 is also effective in at least one axial direction Ax (cf. above). In addition to a frictional engagement (crimping) between the ferrule 200, the turned over end section 642 of the outer conductor 640 and the second contact means 400, or between the ferrule 200 and the second contact means 400, according to the invention an extra mechanical locking feature between the ferrule 200 and the second contact means 400 is established. This extra locking feature is preferably established by locking, blocking or retaining the ferrule 200 and the second contact means 400 in at least one axial direction Ax, preferably in a counter-plugging direction of the connection device 100. The locking between the ferrule 200 and the second contact means 400 serves as strain relief at cable pull. A single connector 1 of the four in In the present case, preferably primary fixing of a connection device 100 in the connector housing 10 is achieved in particular by means of a contact lock 17 or a retainer 17 that can be inserted into and/or be passed through the connector housing 10 (see Corresponding to this, the connection device 100 or the second contact means 400 has a locking means 470 at/in which the contact lock 17 or the retainer 17 can engage (see for example Furthermore, the connection device 100 can have as an optionally secondary locking means a locking strap preferably made to be resilient and which can engage with a correspondingly formed locking means in the connector housing 10. This type of locking strap can be cut free from or be punched out of the connection device 100 or, respectively, the second contact means 400 and be bent open. - This type of locking means can also be considered as a primary lock, a possible optional (cable pulling-off forces) lock by means of the contact lock 17 or the retainer 17 then being able to be called a secondary lock. - The use at least of a contact lock 17 or a retainer 17 is preferred due to cable pulling-off forces that occur and the only small dimensions of a possible locking strap (mini-connector 1). In this case, the four connectors 1 shown are in the form of flying, coaxial plug connectors 1. It is of course possible to apply the invention to all electrical connections, preferably at least one contact cavity being equipped with a connection device 100 with a coaxial cable 60 electrically connected to the latter. It is thus e.g. possible to apply the invention to a pin, male, tab, female, jack or hybrid plug connector 1, a (flying) coupling 1, a (built-in) plug, a (built-in) bushing, a plug receiver, a bushing receiver, a header, an interface etc. Preferably, the invention can be applied to a connector 1 that is designed according to the FAKRA standard (FAKRA = Fachkreis Automobil (Automotive Specialist Group)) which applies in particular to RF- (RF = Radio Frequency) or HF-plug connections (HF = High Frequency) in the automotive industry.
