Electrical connectors for coaxial cables
First Claim
1. An electrical connector for a coaxial cable of the type including a solid tubular dielectric having an inner conductor fitting therethrough and at least an outer tubular conductor covering along said dielectric, said connector comprising a contact wedge assembly, a body assembly and a nut assembly with said contact wedge assembly being pressed fit between said body and nut assemblies as they are connected together, said contact wedge assembly comprising an electrically conductive tapered funnel element for slidably receiving therein the end portion of the tubular dielectric of the cable whereby said tapered element shall lie between said dielectric and the outer tubular conductor of the cable and shall contact said outer tubular conductor, said contact wedge assembly comprising receptacle means to receive the extending bare end of the inner conductor, said nut assembly comprising an aperture to receive the cable and a clamping ferrule, said aperture terminating in said clamping ferrule, said ferrule capable of moving towards the end of the cable when the cable is associated with said tapered funnel element to cooperate with said tapered funnel element to clamp the outer tubular conductor of the cable between said ferrule and said tapered funnel element, said body assembly comprising a body telescoped in a coupling nut, said body comprising thin metal walls surrounding a central dielectric and terminating in a body seat facing said electrically conductive tapered element, and gripping means for holding said electrically conductive tapered element fixed to said body seat to prevent relative rotation between said inner conductor and said electrically conductive tapered element as said electrically conductive tapered element is pressed against said body seat, said gripping means comprising teeth extending oppositely from said taper, said teeth and said electrically conductive tapered element being integrally formed together and being of a metal material harder than the material of said body whereby edges of said teeth will bite into said body seat as said body and tapered element are drawn together.

Abstract
An electrical connector for solid dielectric-filled coaxial cables which comprises three main elements is disclosed. A central contact wedge assembly is adapted to fit into a body and is held there by means of a nut assembly screwed into the body. Gripping means are provided between the body and wedge to prevent twisting of the cable and conductor as the connector is assembled. A lubricated washer located in the nut assembly further enhances the anti-twist action of this invention.
