Abstract
A two part coaxial cable connector includes a rear nut housing a 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 surfaces or ramps compress the ferrule at opposed edges to squeeze the ferrule into gripping engagement with the sheath. 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 overtighting and resulting damage.
