JACKETED METAL CLAD CABLE CONNECTOR

摘要

T/AB 840: A liquid- tight connector for joining a jacketed flexible metal clad cable to an electrical enclosure with a continuous ground path between the cladding and the en- closure. To a standard body gland nut arrangement is added a sealing ring and a grounding ring effectively operated to grip the cable jacket and metal cladding respectively as the gland nut is tightened upon the body. Reduction of the sealing ring bore to cause the ring to grip the cable jacket is accomplished by an undercut in the ring wall and a dual outer diameter arrangement which deforms the sealing ring as its enlarged portion is forced into the body bore and as the ring is compressed between the gland nut and stops on the grounding ring. The sealing ring further operates the grounding ring whose upstanding arms are moved and deformed into intimate contact with the metal cladding of the cable. Supports on the arms assure proper displacement of the arms while stops insure proper compression of the sealing ring.
