An apparatus for and method of making a connection between an electrical conductor and an anode so that the conductor is attached to the anode to supply electrical energy thereto for use in cathodic protection systems. The apparatus includes male and female members of electrical conducting material having cooperating frusto-conical surfaces and such members are received within a bore in an anode. Normally the male member is connected to the electrical conductor and is positioned at the bottom of the bore after which the female member is forced over the male member which causes the female member to expand into intimate engagement with the side walls of the bore. The method includes the steps of placing a male member having a frusto-conical outer surface into a bore of an anode and then forcing a female member having a cooperating frusto-conical inner surface onto the male member to cause the female member to expand into intimate engagement with the walls of the bore. |

A bus bar of laminar construction useful for power distribution systems and the like is disclosed with a method of fabricating the bus bar and installing suitably provided contact pins or posts. The method comprises stacking conductive plates and dielectric plates alternatively, encapsulating the conductive and dielectric plates in a solidifiable dielectric medium, drilling apertures through the medium and specified conductive plates, driving the pins and an amount of solidifiable material provided therewith into the apertures and into contact with the conductive plates, and solidifying the solidifiable material to secure the pins in the apertures. |

A stab type isolating connector for offset joints in enclosed high voltage electric bus apparatus comprises a removable contact rod for connecting laterally offset terminal ends of linear bus conductors within an enclosing sheath. The contact rod is slidable through a transverse passage in one terminal end into and out of engagement with a contact socket in the other terminal end, making contact with both terminal ends in its fully engaged position. Preferably the contact rod is tubular and slides over a guide rod secured within the contact socket. The guide rod may be sectional so that after seating of the contact rod a section of the guide rod may be used to secure the contact rod in engaging position. |

Inner conductors of isolated phase bus sections arranged end to end are joined by a multiplicity of longitudinally extending, annularly arrayed contact fingers which are biased radially inwardly against the conductors being joined with one end of each finger riding in a groove provided therefor on the exterior of one conductor and the other end of the finger being biased against the end of the next adjacent conductor to make slidable contact engagement therewith; a single dielectric shield surrounds both ends of the conductors and the contact fingers and is non-rigidly fastened at its longitudinal ends to the respective shells around each of the endwise adjacent conductors; springs extend between the shield and the fingers to bias the fingers against the conductors; the shield and finger arrangements permit the maximum width for the inner conductors enabling maximum quantities of contact fingers to be used and this arrangement also permits great misalignment between conductors, or tilting of one conductor with respect to the other and enables compensating for ambient condition caused contraction and expansion of the conductors themselves. |

A pair of television receiver high voltage connectors, connecting the receiver high voltage rectifier to the cathode ray tube anode lead and the high voltage transformer, each include a resilient sleeve in which a cup-shaped contact and insulated wire together with an axially compressible spring are supported within a receptacle, formed by a portion of the sleeve inner surface and the cup-shaped connector. The receptacle expands to accommodate the insertion of the end portion of the high voltage rectifier forming an air-tight enclosure for the connection which is completed by the compression of the spring between the contact and rectifier. |

In a preferred form, this disclosure relates to an electrical connection of conductor leads and to a method of making the connection. The electrical connection comprises an elongated planar metal carrier strip having a plurality of crimping flanges integrally connected by webs to one side thereof and with the crimping flanges being crimped to one end of an electrical lead and with the webs being bent so that the plane of the carrier strip extends transversely of the axes of the one ends of the leads, an insulator means made from an elastic insulating material including first and second insulator bodies disposed side-by-side and molded around different ones of the ends of the leads and the adjacent carrier strip portion and having an integral hinge means molded about an intermediate portion of the carrier strip, the first and second insulator bodies being relatively movable by bending the hinge means and the intermediate portion of the carrier strip of the hinge means from the side-by-side position to a second position in which adjacent surfaces are juxtaposed whereby the leads are oriented in desired directions, and a cooperable latching means on the first and second insulator bodies to latch the insulator bodies in their second position when moved thereto.

A current take-off unit is provided which may be readily connected to or disconnected from an external current-carrying element. The unit includes a housing having an opening formed in a wall thereof. The housing is positioned so that the wall opening is disposed adjacent the external element. A conductor means is disposed within the housing and has a portion thereof terminating at the wall opening. Adjustably mounted on the terminating portion of the conductor means is a connector assembly which is adapted to be moved between extended or retracted positions relative to the wall opening. The assembly includes a pair of conductive jaw members which are adapted to project through the wall opening and grippingly engage the external current-carrying element. The assembly also includes an elongated member which extends transversely through the jaw members and conductor means portion and retains same in an assembled relation. The elongated member carries a manually adjustable means which when adjusted in one direction causes the jaw members to move towards one another into gripping engagement with the external element. When the adjustable means is manually adjusted in a second direction, the jaw members can be moved out of gripping relation, whereby the jaw members can assume either an extended or retracted position.

Respective bare end portions of two or more bus bars are joined mechanically and electrically by a connector of conductive material. A casing spacedly encloses the connector, the bare end portions of the bus bars, and adjacent portions of the bus bars which are enveloped by tubular members of insulating material. The tubular members are fastened to the casing whose interior is hermetically sealed and filled with insulating fluid injected into the casing through longitudinal passageways in the bus bars.

There is disclosed a hollow contact pin comprising a tubular section which is open at one end to receive one or more wires and having extending from its closed end and integral therewith a solid elongate conductor polyhedron in cross-section forming a wire wrap terminal. The tubular part may have an inwardly extending finger to grip any wire placed therein. The method disclosed herein includes the steps of drawing a flat strip of wire into tubular form, then swaging the tube to a diameter determined for the socket portion, at the same time swaging a further advanced portion of the tube to reduce the diameter to form a solid circular rod, at the same time at an advanced portion of the workpiece swaging the circular portion to form a wire wrap terminal which is substantially square in crosssection, and at the same time piercing the forward end of the most advanced tubular socket portion to open and flare the same, and finally separating the completed socket pin-wire wrap terminal from that following it. If the socket portion is to be provided with a wire-engaging finger, the flat strip is first lanced at determinate distances before being drawn into tubular form.
