Abstract
Abstract A cable terminator assembly for a coaxial cable includes a housing having araided extension affixed thereto for transferring tensile strength from a cable to the housing and braided extension. An inner cylindrical piece is swaged to the housing for holding the braided extension in place. A dielectric clamp with a closure ring, flat locking washer and cap complete the components within the termination. The washer is keyed to the housing and, together with the housing, clamp the stranded cable conductor. The keying prevents turning of the mating components so that the stranded cable conductor will not be damaged. The clamping of the strands makes electrical contact between the strands and the assembly. The dielectric clamp is forced to bite into the dielectric material of the coaxial cable. This provides a firm mechanical hold.
