Abstract
Abstract This invention relates to an insulated high voltage electrical connector for splicing together cable carrying high currents at high voltages. More particularly, the invention includes a current-carrying connector housing which contains a power-driven piston assembly for driving wedge-shaped jaws onto the center conductor of the cable. An internal shield positioned at either end of the housing modulates voltage potential lines to prevent dangerous stress buildup. Between the housing and a molded external shield, a continuous body of insulation is provided. Vent tubes provide escape means for otherwise trapped air and gases which could contaminate the semi-conductive and nonconductive members. The integrity of the molded external shield is maintained by placing ignition wires through the ends of the connector to the power-driven piston assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A high voltage electrical connection comprising: a. a semi-conductive tubular external shield; b. a current-carrying housing positioned within said shield; c. a body of insulation positioned between the housing and the inside of the shield and bonded to the surfaces thereof, said body of insulation defining cable receiving passageways extending from either end of the shield to the housing; d. two cables of the type having a center conductor and a metallic shield with insulation in between, each positioned in one of the passageways and in the housing, the portion of the cables in the housing having the metallic shield and insulation removed therefrom; e. two metallic conductor adapters, each having an inner perforated sleeve and a plurality of segments fixed on the sleeve in spaced annular relation, each of said conductor adapters being in crimped engagement with the center conductor of the cable extending into the housing; and f. two sets of tapered jaws, each set being driven onto one of the conductor adapters thereby crimping the adapters into crimped engagement with the center conductors.
Claim 2
Dependent Claim
176 words
A high voltage electrical connection comprising: a. a semi-conductive tubular external shield; b. a current-carrying housing positioned within said shield; c. a body of insulation positioned between the housing and the inside of the shield and bonded to the surfaces thereof, said body of insulation defining cable receiving passageways extending from either end of the shield to the housing; d. two cables of the type having a center conductor and a metallic shield with insulation in between, each positioned in one of the passageways and in the housing, the portion of the cables in the housing having the metallic shield and insulation removed therefrom; e. two metallic conductor adapters, each having an inner perforated sleeve and a plurality of segments fixed on the sleeve in spaced annular relation, each of said conductor adapters being in crimped engagement with the center conductor of the cable extending into the housing; and f. two sets of tapered jaws, each set being driven onto one of the conductor adapters thereby crimping the adapters into crimped engagement with the center conductors.
Claim 3
Dependent Claim
23 words
The connection of claim 1 further including two molded insulated sleeves, each positioned between one of the cables and the body of insulation.
Claim 4
Dependent Claim
42 words
The connection of claim 1 further including two molded semi-conductive collars, each positioned between the metallic shield on one of the cables and the external shield whereby electrical continuity between the metallic shield of the cables and the external shield is provided.
Claim 5
Dependent Claim
191 words
A high voltage electrical device useful for splicing two cables together, the cable being of the type having a center conductor, a metallic shield and insulation therebetween; said device comprising: a. a semi-conductive, generally tubular external shield; b. a current-carrying housing positioned within the external shield and having within a propellant charge and two slidably mounted pistons extending outwardly from either side of the propellant charge; c. insulation positioned between the housing and shield and bonded to each, the insulation defining cable-receiving passageways extending from either end of the shield to the housing; d. a pair of gripping means each adapted for being moved into gripping engagement with an end of a cable which may be inserted into the housing; e. retaining means for attaching and retaining each of the gripping means to an end of the pistons; f. means for detonating the propellant charge whereby the pistons drive the gripping means into gripping engagement with the ends of cables which may be inserted into the housing; and g. vent tubes extending from the housing to without the external shield whereby gases developed upon detonating the propellant charge may be released.
Claim 6
Dependent Claim
191 words
A high voltage electrical device useful for splicing two cables together, the cable being of the type having a center conductor, a metallic shield and insulation therebetween; said device comprising: a. a semi-conductive, generally tubular external shield; b. a current-carrying housing positioned within the external shield and having within a propellant charge and two slidably mounted pistons extending outwardly from either side of the propellant charge; c. insulation positioned between the housing and shield and bonded to each, the insulation defining cable-receiving passageways extending from either end of the shield to the housing; d. a pair of gripping means each adapted for being moved into gripping engagement with an end of a cable which may be inserted into the housing; e. retaining means for attaching and retaining each of the gripping means to an end of the pistons; f. means for detonating the propellant charge whereby the pistons drive the gripping means into gripping engagement with the ends of cables which may be inserted into the housing; and g. vent tubes extending from the housing to without the external shield whereby gases developed upon detonating the propellant charge may be released.
Claim 7
Dependent Claim
20 words
The high voltage electrical device of claim 4 wherein each of said gripping means includes a plurality of tapered jaws.
Claim 8
Dependent Claim
28 words
The high voltage electrical device of claim 4 further including a pair of cone-shaped metallic coil springs, each being fixed to an outwardly facing end of the pistons.
