ABSTRACT:
A connector for making connection to an end of an electrical conductor cable to be pulled through conduits or the like comprises a centrally-bored inner connector member having a conical outer surface wedged into a correspondingly conical recess in an outer connector member, with an outer portion of the end of the conductor cable grasped between the two conical surfaces and an inner portion of the cable end gripped within the central bore of the inner connector member. The inner conical member is made of a material which is highly malleable with respect to the inner surface of the outer connector member and at least as malleable as the material of the cable, and sufficient wedging force is provided between the inner and outer connector members so that both the inner and outer portions of the conductor cable become embedded to a substantial extent in the material of the inner connector member. This embedding enhances the strength with which the inner and outer connector members grasp the inner and outer cable portions. The wedging action may be provided by the normal forces used to pull the cable. A preferred material for the inner connector member is aluminum of a purity of at least 80% and preferably greater than 95%, with an elongation of at least 20% and preferably greater than 30%, and a Brinell hardness number no greater than 40 and preferably less than 25.
