Abstract
Abstract A separable connector module for connecting shielded electrical power cable. It is of the type including an insulating housing containing a cable insert member. A male contact rod assembly, including a metal contact rod, is fixed at one end to the insert member. An insulating arc follower is fixed to the rod at its other end. An insulating mounting pin extends from the end of the rod and along at least a portion of the interior of the follower. The improvement comprises an electrically conducting coating on the mounting pin and in electrical contact with the rod.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A rod connector module for separably connecting shielded electrical power cable, comprising: an insulating housing containing a contact rod support; a contact rod assembly, including a metal contact rod to be received by a bore contact, said rod being fixed at one end to said support; an insulating arc follower fixed to said rod at its other end for insertion into the bore, and an insulating mounting pin extending from the end of said rod along at least a portion of the interior of said follower, wherein the improvement comprises, an electrically conductive coating on said pin and in electrical contact with said rod.
Claim 2
Dependent Claim
104 words
A rod connector module for separably connecting shielded electrical power cable, comprising: an insulating housing containing a contact rod support; a contact rod assembly, including a metal contact rod to be received by a bore contact, said rod being fixed at one end to said support; an insulating arc follower fixed to said rod at its other end for insertion into the bore, and an insulating mounting pin extending from the end of said rod along at least a portion of the interior of said follower, wherein the improvement comprises, an electrically conductive coating on said pin and in electrical contact with said rod.
Claim 3
Dependent Claim
19 words
The module of claim 1 wherein said pin is a bundle of glass fibers bonded together with a resin.
Claim 4
Dependent Claim
17 words
The module of claim 2 wherein said pin extends substantially to the free end of said follower.
Claim 5
Dependent Claim
29 words
The module of claim 3 wherein said coating extends along a major portion of the length of said pin and begins where said pin is joined to said rod.
Claim 6
Dependent Claim
30 words
The module of claim 4 wherein said coating has a resistance per unit length of about 1/100 times the resistance per unit length of the adjacent follower material, or less.
Claim 7
Dependent Claim
16 words
The module of claim 5 wherein said coating consists essentially of carbon particles bonded by polyurethane.
Claim 8
Dependent Claim
117 words
The module of claim 1 wherein: said pin is a bundle of glass fibers bonded together by epoxy resin and clamped at one end inside an opening in the end of said rod; said coating extends from the clamped end of said pin to within between one and two centimeters of its end and consists essentially of carbon particles bonded by polyurethane; said follower is an ablative resin composition and extends as far from the end of said rod as does said pin, and said housing is a shielded, molded elastomer elbow housing having an elongated entrance opening for receiving a matching portion of a bore connector module, said contact rod being located coaxially in said opening.
