Coaxial cable connector

Claim 1

In a connector for coaxial cables of the RF type, a combination which permits one connector to be suitable for use on a group of cables having the same impedance characteristics and similar nominal size but different structural details, said combination comprising: 1. a backshell having an inner cylindrical surface of larger diameter than the outer conductor of the largest of said group of cables, 2. a body adapted for connection to the forward end of said backshell having an inner cylindrical surface of larger diameter than said surface of said backshell and containing: a. a mass of dielectric material snugly fitting within said cylindrical surface of said body and essentially filling said body and having a frustoconical surface extending rearwardly and radially inwardly from said cylindrical surface of said body to at least traverse the radial distance to said inner cylindrical surface of said backshell and b. a central conductor contact snugly fitting within said dielectric material, said contact having a rearwardly facing tubular portion of sufficient inner diameter to receive therewithin the largest inner conductor of said group of cables, and a forwardly facing portion adapted for connection with the inner conductor of a second connector, and said body having a forward portion adapted for connection with a second connector, 3. a collar of a conducting material having a forwardly facing frustoconical surface complementary to said frustoconical surface of said mass of dielectric material and extending from said inner cylindrical surface of said body to at least traverse the radial distance to said inner cylindrical surface of said backshell and having a rearwardly facing and rearwardly and radially inwardly extending generally frustoconical surface, 4. a seat having a forwardly facing frustoconical surface complementary to said rearwardly facing surface of said collar, said complementary frustoconical surfaces on said seat and collar adapted for receiving an outwardly and forwardly flared end of the outer conductor of said cable therebetween, the longitudinal position of said seat and said collar being generally between that of said inner cylindrical surfaces of said backshell and said body and said complementary frustoconical surfaces of said seat and said collar generally traversing the radial distance between said inner cylindrical surfaces, 5. complementary fastening means of said body and said backshell, the operation of which fastens said body to said backshell and forces said collar and seat together against said flared end of said outer conductor.
