Abstract

Abstract A high-voltage connector construction capable of use in submersible or exposed areas. The metallic connector itself and its connection to the conductor of a shielded cable are surrounded by a semi-conductive body of elastomeric material which engages the cable metallic connector and acts to prevent voltage differential and resulting corona within air gaps in and around the connection. A two-piece insulating housing of elastomeric material surrounds the semi-conductive body. The housing has a conductive or semi-conductive outer coating sprayed or dipped onto its outer surface, the outer surface being engaged in a sealing relation with a moisture seal, the moisture seal being fabricated of conductive or semi-conductive elastomeric material and being capable of sealing the entrance of the cable to the insulating housing and conductively engaging the cable shield.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 168 words
An electrical connector structure for providing a waterproof electrical connection from the conductor of a high voltage shielded cable, wherein said cable has an outer conductive shield, an insulating sheath within said shield and an electrical conductor within the sheath, and wherein a section of the shield is removed to expose a section of the sheath, and a section of the sheath is removed to expose one end of said electrical conductor, a connection member for mechanically and electrically connecting to the one end of said conductor; the invention comprising: an elastomeric semi-conductive shielding member surrounding the exposed end of the conductor and said connecting member and engaging said cable sheath, a dielectric housing of waterproof elastomeric material surrounding said shielding member and engaging said sheath, a slip-on moisture sealing member of conductive elastomeric material sealingly engaging one end of said housing and said cable shield to cover the joinder of said cable to said housing, said sealing member forming a conductive connection to said cable conductive shield.
Claim 2
Dependent Claim 168 words
An electrical connector structure for providing a waterproof electrical connection from the conductor of a high voltage shielded cable, wherein said cable has an outer conductive shield, an insulating sheath within said shield and an electrical conductor within the sheath, and wherein a section of the shield is removed to expose a section of the sheath, and a section of the sheath is removed to expose one end of said electrical conductor, a connection member for mechanically and electrically connecting to the one end of said conductor; the invention comprising: an elastomeric semi-conductive shielding member surrounding the exposed end of the conductor and said connecting member and engaging said cable sheath, a dielectric housing of waterproof elastomeric material surrounding said shielding member and engaging said sheath, a slip-on moisture sealing member of conductive elastomeric material sealingly engaging one end of said housing and said cable shield to cover the joinder of said cable to said housing, said sealing member forming a conductive connection to said cable conductive shield.
Claim 3
Dependent Claim 42 words
A structure as claimed in claim 1, wherein there is provided a conductive outer layer on said housing, said layer being in conductive contact with said sealing member to complete a conductive path through said sealing member to said cable conductive shield.
Claim 4
Dependent Claim 30 words
A structure as claimed in claim 1, wherein there is a load-break terminator electrode connected to said connector and extending out of said housing at the end opposite said cable.
Claim 5
Dependent Claim 236 words
An electrical connector structure for providing a shielded, waterproof electrical connection from the conductor of a high voltage shielded cable to a conductive member, wherein said cable conductor has a sheath of insulating material about said conductor and an electrically conductive shield surrounding the sheath, wherein a portion of the cable shield and sheath is removed to expose one end of the conductor, and wherein a conductive member is conductively connected to the exposed end of said conductor; the invention comprising: an elastomeric semi-conductive shield surrounding the connection of the conductor to said conductive member and extending into engagement with said cable sheath, a dielectric housing of waterproof elastomeric material closely surrounding said shield and engaging said cable sheath, a slip-on moisture sealing member of conductive elastomeric material sealingly engaging a side surface of said housing and said cable shield to waterproofingly cover the joinder of said cable to said housing, the body of said sealing member fitted about said housing between the ends of said sealing member, at least one rib on the inner wall of said sealing member engaging the outer surface of said cable shield to waterproofingly seal the joinder of the cable to the housing, and an exterior conductive surface on said housing in conductive engagement with said sealing member to complete a conductively shielding path therethrough from said housing surface to said cable shield, and means for grounding said cable shield.
