Associated rotational locking means and guiding means permit coupling only in a single relative angular position. At the time of locking, the plug subjects an insulating safety disc to a movement of rotation on the receptacle from an initial angular position corresponding to the combination of contacts to be uncovered. The angular position of each contact support is adjustable from phi degrees to phi degrees with respect to guiding means, the displaced contact being angularly displaced by K. phi degrees. Retractable locking means are provided for maintaining the safety disc in its initial position when the plug is disconnected from the receptacle.，下面是Electric connection devices专利的具体信息内容。

权利要求

1. An electric connection device of the type comprising, in combination: a plug and a receptacle each having contacts and constituted by an insulating contact support housed within a casing, said plug and said receptacle carrying associated relatively rotational locking means and associated guiding means arranged to couple these said means in a single relative angular position, locations for said contacts on each of said two supports being uniformly spaced over a circumference with exception of one contact which occupies a displaced position with respect to this spaced arrangement, and a safety disc of insulating material provided with openings adapted to be traversed by said contacts of said plug being pivotally mounted on said receptacle coaxially with said circumference defining said contact locations, said safety disc being rotationally displaced by said plug at the time of locking of said plug to said receptacle from an initial angular position corresponding to a given combination of contacts to be uncovered at finish of locking rotation movement, wherein said contact support of each said plug and said receptacle is adjustable in steps of phi degrees in relative angular position with respect to a respective one of said guiding means associated respectively with said plug and said receptacle, the angular displacement of that contact which is displaced with respect to the uniform spaced arrangement is k. phi degrees, k being a whole number and retractable locking means provided for maintaining said safety disc in its initial position at a time of disconnection of said plug from said receptacle.

2. An electric connection device as claimed in claim 1, wherein the means for locking the safety disc in its initial position are constituted by 360/ phi slots formed on a peripheral flange of said disc and adapted to cooperate with lugs carried by an annular washer urged in contact with said flange by elastic means and mounted in such manner as to be axially displaced by the plug in opposition to said elastic means during insertion of said plug.

3. An electric connection device as claimed in claim 1, comprising resilient receptacle contacts, wherein the means for locking the safety disc in the initial angular position selected is carried out by cooperation of at least one resilient receptacle contact with a recess formed in the internal face of said safety disc.

4. An electric connection device as claimed in claim 1 and comprising four poles in which the angular dispLacement phi between two consecutive angular positions of a contact support with respect to the guiding means is 15* whilst the three phase contacts are disposed at intervals along their positionlocation circumference starting from the neutral at locations of 90*, 180* and 285* in the reverse direction.

5. An electric connection device as claimed in claim 4, wherein the safety disc is provided with six openings disposed from one of said openings taken as a point of origin at 15*, 90*, 180*, 195* and 285* in the reverse direction.

6. An electric connection device as claimed in claim 5, wherein those of said openings in the safety-disc which are displaced by 15* are connected by a slot which surrounds these openings.

7. An electric connection device as claimed in claim 5, wherein said safety disc is rotatable between each possible initial position thereof and the corresponding connection position through an arc having an amplitude of 37*30'' in the reverse direction.

8. An electric connection device as claimed in claim 1, including a shield having a projecting annular flange, and wherein the guiding means for coupling the plug to the receptacle are constituted by a lug carried by the plug casing and cooperate with a slot formed in said projecting annular flange of said shield whilst the insulating support of the receptacle is stationarily fixed within its casing and the insulating support of the plug is adjustable for orientation with respect to said lug, the projecting annular flange of the shield is provided on the face directed towards the receptacle with a plurality of notches uniformly spaced at intervals of 15*, one of said notches being intended to be opened at the moment of assembly so as to constitute the guiding slot.
