Abstract
Abstract The invention relates to a device for use in splicing high voltage cables. The device includes an elongated outer semi-conductive section, an elongated inner insulative section and an inner annular semi-conductive section which serves as a corona shield. The inner semi-conductive section has a plurality of circumferentially spaced ribs extending radially inward and having a longitudinal extent which is equal to a major portion of the length of the inner annular semi-conductive member. In use, the bare wire ends of a pair of high voltage cables to be spiced are electrically connected by means of a tubular metal connector. The circumferentially spaced ribs are in electrical and thermal contact with the metal connector. The ends of the outer semi-conductive section are electrically connected to the outer covering of the high voltage cables by means of semi-conductive end caps which have a radial dimension approximately equal to that of end portions of the outer semi-conductive section and overlap the ends such that their position can be longitudinally adjusted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
207 words
A high voltage cable splice comprising: a pair of high voltage cabled having lengths of exposed bare wire ends and outer shells; an electrical connector electrically joining said bare wire ends; and an elongated member positioned on said cables in overlying relation to said bare wire ends and said electrical connector and having, an inner annular semi-conductive section, said inner annular semi-conductive section having a longitudinal extent greater than the length of the bare wire ends, thereby encompassing said bare wire ends and providing a corona shield section, said inner annular semi-conductive section having plurality of circumferentially spaced ribs, extending radially inwardly and having a longitudinal extend which is equal to a major portion of the length of said electrical connector, each rib making contact with said connector over substantially its entire length, the uncompressed radial inward length of each rib being greater than the radial distance between said inner annular section and said electrical connector, said ribs thereby being maintained under a compressive force over substantially their entire length; whereby said ribs present extensive contact surfce to said connector; an elongated intermediate insulative section overlying and encompassing said inner annular semi-conductive section; and an outer elongated semi-conductor section overlying and encompassing said elongated intermediate insulative section.
Claim 2
Dependent Claim
207 words
A high voltage cable splice comprising: a pair of high voltage cabled having lengths of exposed bare wire ends and outer shells; an electrical connector electrically joining said bare wire ends; and an elongated member positioned on said cables in overlying relation to said bare wire ends and said electrical connector and having, an inner annular semi-conductive section, said inner annular semi-conductive section having a longitudinal extent greater than the length of the bare wire ends, thereby encompassing said bare wire ends and providing a corona shield section, said inner annular semi-conductive section having plurality of circumferentially spaced ribs, extending radially inwardly and having a longitudinal extend which is equal to a major portion of the length of said electrical connector, each rib making contact with said connector over substantially its entire length, the uncompressed radial inward length of each rib being greater than the radial distance between said inner annular section and said electrical connector, said ribs thereby being maintained under a compressive force over substantially their entire length; whereby said ribs present extensive contact surfce to said connector; an elongated intermediate insulative section overlying and encompassing said inner annular semi-conductive section; and an outer elongated semi-conductor section overlying and encompassing said elongated intermediate insulative section.
Claim 3
Dependent Claim
27 words
The splice of claim 1, wherein said ribs are spaced from each other by a distance which is substantially equal to the radial length of said ribs.
Claim 4
Dependent Claim
28 words
The splice of claim 1, wherein said ribs are made of an elastomeric material and have a hardness on the order of a 60 Shore A durometer hardness.
Claim 5
Dependent Claim
20 words
The splice of claim 1, wherein said elongated member is pliant and radially extensible and compressively grips said outer shells.
Claim 6
Dependent Claim
15 words
The splice of claim 1, wherein said spaced ribs are at least six in number.
