ABSTRACT:
There is provided a plastic collar integral with the outer jacket of a cable. The plastic material includes a mixture of a plastic and an electrically conductive material such as carbon black. The plastic is melt bonded to the cable jacket by applying electric current through the material, thus melting the material onto the jacket of the cable. Upon melting, the semi-conductive plastic may be molded into the desired form, and upon cooling, it becomes bonded to the cable jacket. The collar may be used as a seal for the ends of a cable splice closure as well as a shoulder for securing a sealing gasket to a cable for use in such closures. The collar also may be used as strain-relief for the conductors which are inside the cable as well as other uses.
