Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A method for providing a collar integral with a cable jacket including the steps of: applying a semi-conductive plastic material to the cable jacket; compressing said semi-conductive plastic material axially and radially; placing a pair of spaced apart electrodes on said material; passing electric energy from said electrodes through said material itself in sufficient quantity and for a sufficient time utilizing the conductive and the resistive qualities of said semi-conductive plastic material to melt-bond said material to the jacket.
Claim 2
Independent Claim
79 words
A method for providing a collar integral with a cable jacket including the steps of: applying a semi-conductive plastic material to the cable jacket; compressing said semi-conductive plastic material axially and radially; placing a pair of spaced apart electrodes on said material; passing electric energy from said electrodes through said material itself in sufficient quantity and for a sufficient time utilizing the conductive and the resistive qualities of said semi-conductive plastic material to melt-bond said material to the jacket.
Claim 3
Dependent Claim
