Abstract

The present invention provides a connector used to interconnect a hard-line coaxial cable to an equipment port. The connector of the present invention essentially comprises a main connector body in which the various connecting and sealing members are housed, and a compression body attached to the connector body for axial, sliding movement between first and second terminal positions relative to the connector body. The port side of the connector includes a conductive pin extending axially outwardly therefrom that is adapted to be inserted into the port provided in the equipment box, and an axially extending bore is formed though the distal end (cable side) of the connector and compression bodies for receiving the central conductor of the hard-line cable therein.
