Abstract

A coaxial cable connector comprising first and second matable housing means each having a semi-cylindrical channel formed therein which coincide when the housing means are mated to form one full cylindrical channel in which the cable is retained. A center conductor probe and a braid tap extend out of the semi-cylindrical channel of said first housing means to penetrate the cable as the housing means are mated. The braid tap comprises a pair of prongs secured to a common plate. The prongs penetrate the braid and, as the housing means are fully mated, the metal supporting plate bends to rotate the prongs towards each other to grip the braid therebetween. A spring loaded back-up probe is advanced from the semi-cylindrical channel in said second housing means after mating of the housing means to penetrate the cable and press against the center conductor thereof opposite the contact point of the center conductor probe.
