Abstract
A connector adapted to be positioned on an end of an armored electrical cable of the type having protective flexible cable armor formed by interlocked helical convolutions of a metallic strip and serving for facilitating securing a grounding conductor to the cable armor. The connector comprises an electrically conductive spring-like element having a plurality of helical turns. The spacing and pitch of the helical turns of the connector correspond to the spacing and pitch of the helical convolutions of the cable armor for threadedly engaging the helical convolutions. One end portion of the spring-like element extends longitudinally away from the helical turns to position the end of the element in a readily accessible location for connection of a grounding conductor thereto. The connector may optionally additionally include a flexible sleeve adapted for receiving and tightly engaging the end portion of the cable armor with the spring-like element positioned thereon and securing the end portion of the cable armor to an electrical panel or junction box.
