BUFFERING APPARATUS FOR MESSENGERED CABLES

摘要

A tensile-force buffering apparatus interposes a physical structure and a drop clamp having a messenger of an input drop cable secured thereto. The tensile-force buffering apparatus includes an outer housing defining an elongate inner cavity and a retainer, and a spring-strut assembly. The spring-strut assembly includes a central shaft, a retention member at a first end of the central shaft, and a coil spring disposed about the central shaft. The spring-strut assembly is received in the cavity of the outer housing, and the retention member is held by the retainer while a load compressing the coil spring is less than a predetermined threshold load. The retention member is released from the outer housing when the load compressing the coil spring reaches the predetermined threshold load, thereby effecting separation of the spring-strut assembly from the outer housing.
