ABSTRACT:
An electrical connector for connecting flexible metal conduit, armored cable, or metal-clad cable to a panel or junction box. The connector includes a connector body having a tubular nose portion on the leading end and a clamping arrangement on the trailing end. The clamping arrangement includes a fixed clamp arm integral with the connector body and a movable clamp arm that is adjustable with respect to the fixed clamp arm. A tubular insert can be fitted into an inner bore on the tubular nose portion to provide the proper end stop for the cable and to properly insulate the inner bore from any electrical contact with the wire conductors of the electrical cable. The tubular nose portion is exteriorly threaded to accept a lock nut or resilient locking ring for securing the connector to a panel or junction box and for properly grounding the cable to the panel or box.
