ABSTRACT:
A two part coaxial cable connector includes a rear nut body housing a two step ferrule for gripping the sheath of a coaxial cable and a front nut body for gripping the conductor upon threaded engagement of the rear and front nut bodies. A mandrel, located within and protected by the rear nut body, slides within the sheath upon feeding of the cable into the rear nut body. A pair of annular inclined ramps formed in a ferrule encircling sleeve compress the ferrule to squeeze the ferrule into gripping engagement with the sheath while forcing ferrule rearwardly. A brass ring disposed between the ferrule and the end of the rear nut, which ring is compressed upon rearward movement of the ferrule and becomes amalgamated with the sleeve and ferrule to prevent spurious RF radiation from the rear nut body. Simultaneously, a collet in the front nut body is compressed to grip the conductor. To facilitate the feeding of a seamed or off round sheath, the ferrule, mandrel and associated parts float within the rear nut body. A positive visually apparent physical interference between the rear and front nut bodies prevents overtightening and resulting damage.
