Abstract
Abstract A composite bushing for terminating a high-voltage cable which has an electrical conductor, cable insulation and a semiconductive shield. The bushing including an electrically conductive assembly adapted to be electrically connected to the conductor. A sleeve of electrically insulating elastomeric material surrounding the assembly in a spaced relation thereto and extending outwardly from one end thereof, said outwardly extending portion having a passage adapted to sealingly engage the exposed cable insulation. A rigid dielectric housing bonded to the portion of the length of said sleeve around said assembly and to a portion of said assembly, an inner sleeve of electrically conductive elastomeric material provided within said nonconductive elastomeric sleeve and having a length sufficient to bridge the space between the assembly and the nonconductive sleeve. The electrically conductive sleeve having a reduced diameter section at each end to engage the assembly at one end and the cable insulation at the other end.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A cable lead bushing for terminating a high-voltage cable having an electrical conductor and a cable insulation, a portion of the cable insulation and the conductor being exposed, said bushing comprising: a rigid housing having an opening at one end, means supported within said housing for electrically engaging the conductor, a resilient insulating member bonded to said housing and having a passage adapted to sealingly engage the cable insulation, a portion of said resilient insulating member surrounding said electrical engaging means and being spaced therefrom and an inner sleeve of elastomeric electrically conductive material molded to said portion of said insulating member and having a length sufficient to bridge said electrical engaging means.
Claim 2
Dependent Claim
113 words
A cable lead bushing for terminating a high-voltage cable having an electrical conductor and a cable insulation, a portion of the cable insulation and the conductor being exposed, said bushing comprising: a rigid housing having an opening at one end, means supported within said housing for electrically engaging the conductor, a resilient insulating member bonded to said housing and having a passage adapted to sealingly engage the cable insulation, a portion of said resilient insulating member surrounding said electrical engaging means and being spaced therefrom and an inner sleeve of elastomeric electrically conductive material molded to said portion of said insulating member and having a length sufficient to bridge said electrical engaging means.
Claim 3
Dependent Claim
46 words
A cable lead bushing according to claim 1 wherein said inner sleeve includes a reduced diameter section at each end, one of said sections engaging said electrical engaging means, the other of said sections being adapted to engage the cable insulation to form a cavity therebetween.
Claim 4
Dependent Claim
108 words
A bushing for terminating a high-voltage cable having an exposed electrical conductor and a cable insulation, said bushing comprising an inner electrically conductive elastomeric sleeve, an outer electrically insulating elastomeric sleEve molded around said inner sleeve and extending beyond one end of said inner sleeve and having a passage therein for receiving the conductor, a solid dielectric housing bonded to a portion of the length of said outer sleeve and extending beyond the other end of said inner sleeve and, an electrically conductive assembly adapted to be connected to the electrical conductor and supported by said housing in a spaced relation to a portion of said inner sleeve.
Claim 5
Dependent Claim
108 words
A bushing for terminating a high-voltage cable having an exposed electrical conductor and a cable insulation, said bushing comprising an inner electrically conductive elastomeric sleeve, an outer electrically insulating elastomeric sleEve molded around said inner sleeve and extending beyond one end of said inner sleeve and having a passage therein for receiving the conductor, a solid dielectric housing bonded to a portion of the length of said outer sleeve and extending beyond the other end of said inner sleeve and, an electrically conductive assembly adapted to be connected to the electrical conductor and supported by said housing in a spaced relation to a portion of said inner sleeve.
Claim 6
Dependent Claim
17 words
A bushing according to claim 3 including means for locating said conductive assembly within said inner sleeve.
Claim 7
Dependent Claim
23 words
A bushing according to claim 4 wherein said locating means includes a rib in said inner sleeve and a groove in said assembly.
Claim 8
Dependent Claim
23 words
A bushing according to claim 3 wherein said passage has substantially the same diameter as said cable insulation to form a seal-on connection.
