Abstract

Electrical contact for coaxial cables or two-wire cables of the type having a cylindrical body inside which is mounted a contact piece, the body having in its wall elastic exterior portions able to abut against ledge parts inside a cavity hole of a connector body, the contact being constituted of two joinable assembly components, the first or outside component (1 ) comprising a cylindrical body supplied on the outside with means for locking (2) in a cavity hole of a connector body, and extended by a rear tubular part (3), and inside which is fastened and insulating sleeve (4), and the second or inside component, comprising a contact piece (5), a connecting barrel (8) for the conductors of the cable, and an insulator (9) interposed between the barrel and the contact piece.

Claims

1. An electrical connector contact for coaxial cables or two-wire cables comprising, an outer pre-assembled assembly comprising a tubular electrically conductive body having a front electrical contact portion with a rearwardly opening sleeve portion, and an insulating sleeve within and fixed to said body, said sleeve portion having an open rearward end and said insulating sleeve being spaced axially from said rearward end, an inner pre-assembled assembly comprising, a contact body having a contact and a socket with an opening facing away from the contact for rearwardly receiving a conductive end of a first wire of a cable, an insulating bushing fixed to said contact body, and an electrically conductive barrel fixed to said insulating bushing in insulated relation to said contact body, said barrel having an open rearward end for receiving therein an insulated portion of the first wire whose conductive end is inserted in the socket of the contact, said barrel including a conductive surface for electrical connection of a second conductor of the cable, said socket of said contact body including means for electrically connecting the conductive end of the first wire inserted therein to the contact, said contact of said inner assembly being a close slidable fit in said outer assembly, and said barrel being receivable in said rearwardly opening sleeve portion of the outer assembly so that said inner assembly can be inserted forwardly into said outer assembly after connecting the cable to the inner assembly, said rearwardly opening sleeve comprising, means for electrically connecting said front electrical contact portion of the outer assembly to the second wire of the cable, and means for mechanically securing the inner assembly against axial separation from the outer assembly.

2. A connector contact according to claim 1, wherein said socket of the contact body of the inner assembly comprises means for electrically connecting the conductive end of the first wire by crimping.

3. A connector contact according to claim 1, wherein said conductive surface of said barrel comprises an outer surface of the barrel.

4. A connector contact according to claim 3, wherein said barrel comprises a recess in its outer surface for the second conductor.
