US 4,536,611 A · Unitary telephone cable closure

Abstract

An aerial telephone cable closure for enclosing telephone cables suspended from a support strand. The closure consists of a tubular housing having a pair of interfitting mating edges, these edges are fastened after passing the telephone cable through the access slot between the edges. The closure further includes flexible metal hanger brackets which are attached to the outside upper circumferential surface of the closure and which each have a vertical portion projecting upward for the fastening to the aerial support strand by support strand clamps. When it is desired to terminate some of the conductors in the cable for use with telephone service wires, the closure would include a termination port formed in the side of the tubular housing. The termination port includes a rectangular frame formed about a rectangular opening in one side of the tubular housing. A replaceable terminal block panel assembly is installed within the rectangular frame. The replaceable terminal block assembly is comprised of a terminal block panel on which a terminal block is mounted. A rectangular lid is integrally hinged on the top side of the frame for providing access to the terminal block. In this manner, the closure can be fastened about the cable and access can be had to terminate service wires to the terminal block.
