Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A rod connector module for separably connecting shielded electrical power cable, said module comprising: an insulating housing containing a contact rod support; a receiving cone in said housing extending from exterior to said housing toward said support, and a conductive contact rod fixed at one end to said support and extending toward the exterior along the axis of said cone, wherein the improvement comprises a layer of electrically resistive voltage stress grading material on the inside surface of said cone and electrically connected to the supported end of said rod.
Claim 2
Dependent Claim
90 words
A rod connector module for separably connecting shielded electrical power cable, said module comprising: an insulating housing containing a contact rod support; a receiving cone in said housing extending from exterior to said housing toward said support, and a conductive contact rod fixed at one end to said support and extending toward the exterior along the axis of said cone, wherein the improvement comprises a layer of electrically resistive voltage stress grading material on the inside surface of said cone and electrically connected to the supported end of said rod.
