Abstract: This invention relates to an electrical connector assembly including apparatus for securing a metallic coupling ring on a connector body or shell. A metallic retaining ring is secured into the rear of the coupling ring bore through the interaction of an annular sawtooth groove pattern formed on the outside of the retaining ring and on the rear inside of the coupling ring bore. The dimensions of the sawtooth groove pattern are carefully selected so as to permit metallic materials to be used for both rings. The connector assembly includes a pair of shells, each having electrical contacts carried by a dielectric retention disc secured in a respective shell for engagement with the electrical contacts of the other shell. Each shell has a large diameter recess for receiving a large diameter portion of each disc force fit through a small diameter portion of the respective shell to thereafter retain the disc.

Abstract: This invention relates to an electrical assembly, such as an electrical cable assembly, to electrical elements such as electrical connector elements for terminating the assembly, and to housings for electrical elements. The housings for the electrical elements are formed of first and second housing members of insulating material, the housing members having mating sides which are fitted together to form the members into a housing. The first member has a plurality of pins projecting from the mating side thereof and the second member has a hole therethrough for each of the pins. The length of the pins and the relative position of the pins and holes are such that each pin passes through the corresponding hole and is exposed on the side of the second member opposite the mating side. The exposed portion of each pin is cold-flow expanded to hold the members together.

Abstract: An electrical contact member formed from an axially extended tube is provided intermediate its ends with an axially extending insulation-opening slot. The slot is terminated at one end in an entry opening through the tube. The entry opening and an inwardly tapered entry ramp are formed by a free-ended piece of the tube wall bent into the inner opening of the tube. An insulated conductor may be inserted into the contact member in either of two ways: by insertion through the appropriate end of the tube and deflection by the entry ramp through the entry opening; or, by insertion through the entry opening and deflection by the entry ramp through the end of the tube. After insertion by either method, the ends of the insulated conductor may be pulled to force the conductor into a narrowed engagement portion of the slot where the insulation around the conductor is opened by spreading or cutting and electrical contact is made between the tube and the metallic conductor.
