Abstract
Abstract Solderless plug and union connectors for a pair of coaxial shielded cables having a ''''T'''' type body provided with pin bearings or socket bearing junctions for contacting the exposed end of an inner conductor from each of a pair of cables disposed in a transverse plane to the body of the connector. The connector body includes a pair of dielectric material washers, each disposed about the dielectric material sleeve surrounding the inner conductor of one of the cables and having a mating step portion formed thereon for engagement with a similar step portion formed on an abutting metallic sleeve member similarly extending through the connector body. The connector assembly includes a threaded cup member slidably fixed to a second connector member for coupling the ''''T'''' connector and for drawing the ''''T'''' connector and the second connector into tight sealing engagement through the operation of the cup member.
