Abstract

Abstract An electrical connector designed for engagement and disengagement under water at very great depths with high voltage and amperage capacity. The connector incorporates a dummy piston to seal the female electrical contact, which is displaced by the male pin. Sealing means and hydrostatically compensated dielectrical oil supply means are disclosed.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 291 words
An underwater wet electrical connector for use in making up electrical connections in an under sea environment including: a male plug, at lease one male pin extending from the plug, a male contact terminal mounted on each pin, dielectric means electrically insulating the male contact terminal from the male plug, means for electrically connecting an electrical cable conductor to each male contact terminal, a female receptacle, a female contact socket arranged to receive and mate with each male pin within the female receptacle, a female contact block mounted within the socket, the female contact block having a contactor portion arranged to receive the male contact teRminal and provide an an electrical conducting path there between when the male pin is inserted into the female contact socket, dielectric means electrically insulating the female contact block from the female receptacle, means for electrically connecting an electrical cable conductor to each female contact block, a piston reciprocally mounted in the female contact socket arranged to prevent the entrance of sea water into the female contact socket when the male pin is not inserted therein, means retaining the piston in the female contact socket when the male pin is not inserted therein and receiving the piston when displaced from the female contact socket when the male pin is inserted therein, seal means adjacent the exterior of the female receptacle and mechanically alternatively sealing the piston and the male pin when inserted in the female contact socket, and a dielectric oil compensator having biasing means therein providing a positive pressure on the oil at all times, said compensator being mounted within the female receptacle and hydraulically interconnecting an oil supply means with the piston and with the male pin when inserted in the female contact socket.
Claim 2
Dependent Claim 291 words
An underwater wet electrical connector for use in making up electrical connections in an under sea environment including: a male plug, at lease one male pin extending from the plug, a male contact terminal mounted on each pin, dielectric means electrically insulating the male contact terminal from the male plug, means for electrically connecting an electrical cable conductor to each male contact terminal, a female receptacle, a female contact socket arranged to receive and mate with each male pin within the female receptacle, a female contact block mounted within the socket, the female contact block having a contactor portion arranged to receive the male contact teRminal and provide an an electrical conducting path there between when the male pin is inserted into the female contact socket, dielectric means electrically insulating the female contact block from the female receptacle, means for electrically connecting an electrical cable conductor to each female contact block, a piston reciprocally mounted in the female contact socket arranged to prevent the entrance of sea water into the female contact socket when the male pin is not inserted therein, means retaining the piston in the female contact socket when the male pin is not inserted therein and receiving the piston when displaced from the female contact socket when the male pin is inserted therein, seal means adjacent the exterior of the female receptacle and mechanically alternatively sealing the piston and the male pin when inserted in the female contact socket, and a dielectric oil compensator having biasing means therein providing a positive pressure on the oil at all times, said compensator being mounted within the female receptacle and hydraulically interconnecting an oil supply means with the piston and with the male pin when inserted in the female contact socket.
Claim 3
Dependent Claim 48 words
The invention of claim 1 including: the dielectric oil supply means providing dielectric oil interiorly of the seal means at the interface between the piston and the female contact socket and the male pin and the female contact socket as either is inserted in the female contact socket.
Claim 4
Dependent Claim 39 words
The invention of claim 1 wherein the female contact socket includes an elastomer molding interiorly of the seal means providing a squeezing interference fit on the piston and on the male pin when inserted in the female contact socket.
Claim 5
Dependent Claim 78 words
The invention of claim 3 including: a compensator cylinder, a compensator piston having first and second sides, the first side of the piston being mechanically biased toward the second side and being vented to the under sea environment, the second side of the piston and the cylinder being filled with dielectric oil, and piping means directing the oil from the cylinder to the piston and to the male pin as either is inserted in the female contact socket.
Claim 6
Dependent Claim 30 words
The invention of claim 1 wherein the seal means includes O-ring seals arranged to wipe sea water from the male pin as it is inserted in the female contact socket.
Claim 7
Dependent Claim 35 words
The invention of claim 3 including: a compensator mounted within the female receptacle and hydraulically interconnecting the dielectric oil supply means, and the piston, and arranged to hydrostatically balance the piston in the female receptacle.
Claim 8
Dependent Claim 78 words
The invention of claim 6 including: a compensator cylinder, a compensator piston having first and second sides, the first side of the piston being mechanically biased toward the second side and being vented to the under sea environment, the second side of the piston and the cylinder being filled with dielectric oil, and piping means directing the oil from the cylinder to the piston and to the male pin as either is inserted in the female contact socket.
Claim 9
Dependent Claim 30 words
The invention of claim 2 wherein the seal means includes O-ring seals arranged to wipe sea water from the male pin as it is inserted in the female contact socket.
Claim 10
Dependent Claim 23 words
The invention of claim 1 including: anchor means for mechanically interconnecting the electrical cable to the male plug and to the female receptacle.
