ABSTRACT:
A cable clamp includes a housing having a cavity therein with two opposed walls and an open end in communication with the cavity. A pair of wedge shaped jaws are located within the housing and are slideably movable toward and away from the opening. Each of the jaws includes a semi-cylindrical gripping surface which are adapted to move toward each other to grip a cable therebetween when the jaws move toward the opening and are able to move away from each other when the jaws move away from the opening so as to release a cable located therebetween. A spring biases the jaws toward the opening so that they are biased into the gripping position. In order to more positively hold the cable, each of the gripping surfaces includes a plurality of teeth in the form of raised segments of spiral threads. Some of the spiral threads on each of said inserts are right handed and some are left handed to help prevent rotating movement of the cable as it is being gripped. The clamp can be used as a dead end clamp or the housing can contain a second pair of jaws, preferably extending in opposite directions, whereby the clamp is capable of gripping a second cable for electrically and mechanically connecting two cables together.
