Abstract
Abstract The disclosure relates to a connector device for impeding corona discharges in high voltage utility lines in the region of 230 Kv. which can be installed by the use of a hot stick and a hot stick applicator for holding the corona-impeding connector during application thereof to the line, the corona-impeding connector including a set of gripping jaws which lockingly grips upon the cable due to compression thereof by means of an explosive tool or the like which forces the jaw member along an inwardly tapered portion of the corona-impeding connector to place same in compression against the cable and make a locking fit therewith. The disclosure also relates to a hot stick applicator of conductive material and coated with a nonabrasive substance, at least in the areas which come in contact with the corona-impeding connector, to prevent the formation of burrs or the like which may cause corona discharge from the corona impeding connector itself during operation thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
In a connector for an electrical cable, the combination comprising: a tapered cavity in one end of said connector and adapted to receive an electrical cable end, a passageway in said connector and communicating with said cavity, an insert mounted for movement within and toward the narrow end of said tapered cavity, said insert including a plurality of jaws adapted to receive the cable ends there between, each of said jaws being fixedly mounted on said insert in radial spaced relationship, each of said jaws including a weakened portion along its length thereof allowing each of said jaws to be bent individually along its length in cantilever fashion about said weakened portion and radially inward in gripping relationship on said cable end, means communicating with said passageway for forcefully moving said insert toward the narrow end of said tapered cavity, wherein said insert further includes a pusher plate connected to each of said jaws and in alignment with said passageway, said means forcefully reacting against said pusher plate for moving said insert toward the narrow end of said tapered cavity, and wherein said insert further includes a washer overlying a portion of each of said jaws and secured to said pusher plate.
Claim 2
Dependent Claim
202 words

Claim 3
Dependent Claim
19 words
The structure as recited in claim 1, and further including: a setscrew securing said washer to said pusher plate.
Claim 4
Dependent Claim
42 words
The structure as recited in claim 2, wherein, said weakened portion of each jaw is circumferentially spaced from an adjacent jaw, and said washer is located between all of said jaws and adapted to receive the cable end in abutting relationship therewith.
Claim 5
Dependent Claim
18 words
The structure as recited in claim 3, wherein, said connector includes at onE end thereof a bulbed configuration.
Claim 6
Dependent Claim
60 words
The structure as recited in claim 1, and further including: positioning means secured to said jaw members to position said jaw members in the shape of a frustum of a cone, said frustum of a cone having substantially the same shape as said tapered cavity, and said jaw members being spaced from each other to allow radially inward compression thereof.
Claim 7
Dependent Claim
17 words
The structure as recited in claim 5, wherein, the interior surfaces of said jaws include serrations thereon.
