Abstract
Abstract A high voltage high altitude electrical connector is provided which comprises a pair of insulating bushings with complementary and intermatable portions, one bushing constituting a receptacle and the other the mating plug therefor. The plug bushing has a central cavity with a tapered side wall and an electrically conductive contact pin mounted on its center axis. A sealing means is provided at an intermediate position in the cavity wall and surrounding one end of the contact pin. The receptacle bushing has a forward protrusion, the outside surface of which is tapered and shaped to be complementary to the plug cavity. A metal socket contact member which receives the contact pin therein is mounted centrally in the receptacle bushing. Suitable termination mmeans are provided at the opposite ends of the pin and the socket.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
An electrical connector assembly suitable for use with high voltages at high altitudes, said connector assembly comprising a plug member of insulating material and an interconnectable mating receptacle member also of insulating material, said receptacle member containing therein a socket contact member of electrically conductive material and said plug member containing therein an electrical contact pin adapted to mate with said socket contact member, said plug member having a central axial opening to receive said contact pin, said plug member further having a forward central cavity communicating with said opening, said cavity being of conical shape with an inwardly tapering wall, said contact pin having a forward portion engageable with said socket member that extends forward into said cavity, said receptacle member having a cylindrical body with a forward extension of conical shape adapted to fit within said plug cavity when the plug and receptacle members are interconnected, the outer surface of said forward extension then being spaced slightly from said substantially parallel to the side wall of said cavity, and a combined sealing and frictional locking means mounted in the side wall of said cavity in position to surround said contact pin rearwardly of itS free end, and seal a predetermined volume of gas within said connector assembly while frictionally holding said receptacle in engagement with said plug member, the contact pin and socket contact member both terminating within their respective plug and receptacle members.
Claim 2
Dependent Claim
236 words
An electrical connector assembly suitable for use with high voltages at high altitudes, said connector assembly comprising a plug member of insulating material and an interconnectable mating receptacle member also of insulating material, said receptacle member containing therein a socket contact member of electrically conductive material and said plug member containing therein an electrical contact pin adapted to mate with said socket contact member, said plug member having a central axial opening to receive said contact pin, said plug member further having a forward central cavity communicating with said opening, said cavity being of conical shape with an inwardly tapering wall, said contact pin having a forward portion engageable with said socket member that extends forward into said cavity, said receptacle member having a cylindrical body with a forward extension of conical shape adapted to fit within said plug cavity when the plug and receptacle members are interconnected, the outer surface of said forward extension then being spaced slightly from said substantially parallel to the side wall of said cavity, and a combined sealing and frictional locking means mounted in the side wall of said cavity in position to surround said contact pin rearwardly of itS free end, and seal a predetermined volume of gas within said connector assembly while frictionally holding said receptacle in engagement with said plug member, the contact pin and socket contact member both terminating within their respective plug and receptacle members.
Claim 3
Dependent Claim
49 words
The electrical bushing of claim 1 wherein said sealing means comprises an O-ring of an elastomeric material, said cavity side wall having an annular groove therein intermediate the ends of the cavity, the said O-ring being disposed in said groove to be partially recessed within said cavity side walls.
