Abstract

An electrical connector assembly is disclosed for terminating a triaxial or twin axial cable of the type having two center conductors which are dressed for termination to extend forward respective distances free from a dielectric casing, conductive shield, and outer sheath therearound. The assembly includes a center contact, an inner bored body, an inner ferrule, an outer bored body, and an outer ferrule. The center contact is affixed to the end of a forwardmost extending one of the two center conductors and is thereafter inserted into the inner body having preinserted dielectric means for insulating the center contact. The inner ferrule is radially crimped upon a rearward portion of the inner body having a forward uninsulated end of the second cable center conductor position thereagainst. Subsequently, the inner body is inserted into the outer body having preinserted dielectric means for insulating the inner body having a rearward sleeve portion interposed between forward ends of the cable shield and dielectric casing. The outer ferrule is thereafter radially crimped upon the forward end of the cable shield to fixedly common the shield to the outer body sleeve positioned therebeneath.
