Abstract

Abstract A high-altitude, high-voltage electrical connector lead assembly having an externally threaded bushing containing a contact pin, and an external electrical lead containing a contact pin socket. Surroundingly engaging, but longitudinally movable upon the exterior surface of the electrical lead in tightly-fitting fashion is an internally threaded flexible cap. Upon assembling the connector assembly, the lead, with its flexible cap, is grasped so as to insert the end of the lead containing the contact pin socket into engagement with the bushing contact pin. When the socket and pin are thus engaged, the flexible cap is then pushed or slid along the exterior surface of the lead, the flexibility of the cap permitting its internal threads to flexurally ''''skip'''' over the external threads of the bushing. A resilient O-ring is also positioned on the external lead, the Oring being located between the interior face of the flexible cap and the annular end of the bushing. Upon completion of the pushing operation performed upon the cap, the latter may be screw-threaded any remaining distance along the bushing, this operation serving to axially compress and radially expand the resilient O-ring, such that the latter forms a fluid-tight seal.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 161 words
A high-altitude, high-voltage electrical connector lead assembly comprising: a cylindrical bushing; a contact pin element disposed in one end of said bushing; external thread means located upon the other end of said bushing; an insulated electrical lead; a wire conductor disposed in one end of said lead; a contact pin socket disposed in the other end of said lead for mating connection with said bushing contact pin element, said contact pin socket being electrically connected to said lead wire conductor; and internally threaded flexible cap means closed at one end and having a central opening in said closed end for the admission therethrough of said insulated electrical lead, the flexibility of said cap means permitting its internal threads to flexurally skip over the external threads of said bushing when said cap means is forcibly moved longitundinally on said lead in the direction of said bushing, whereby said flexible cap means may be pushed or snapped onto and engaged with, said bushing.
Claim 2
Dependent Claim 161 words
A high-altitude, high-voltage electrical connector lead assembly comprising: a cylindrical bushing; a contact pin element disposed in one end of said bushing; external thread means located upon the other end of said bushing; an insulated electrical lead; a wire conductor disposed in one end of said lead; a contact pin socket disposed in the other end of said lead for mating connection with said bushing contact pin element, said contact pin socket being electrically connected to said lead wire conductor; and internally threaded flexible cap means closed at one end and having a central opening in said closed end for the admission therethrough of said insulated electrical lead, the flexibility of said cap means permitting its internal threads to flexurally skip over the external threads of said bushing when said cap means is forcibly moved longitundinally on said lead in the direction of said bushing, whereby said flexible cap means may be pushed or snapped onto and engaged with, said bushing.
Claim 3
Dependent Claim 77 words
A high-altitude, high-voltage electrical connector lead assembly as set forth in claim 1, wherein the external thread means of said cylindrical bushing are of a zig-zag configuration, and the internal thread means of said flexible cap are of a truncated zig-zag configuration, whereby the particular thread configurations permit said flexible cap means to be pushed or snapped onto said cylindrical bushing means but nevertheless prevent said flexible cap means and said cylindrical bushing from being pulled apart.
Claim 4
Dependent Claim 72 words
A high-altitude, high-voltage electrical connector lead assembly as set forth in claim 1, wherein the external thread means of said cylindrical bushing and the internal thread means of said flexible cap means are of corresponding saw-tooth configuration, whereby the particular thread configurations permit said flexible cap means to be pushed or snapped onto said cylindrical bushing means but nevertheless prevent said flexible cap means and said cylindrical bushing from being pulled apart.
Claim 5
Dependent Claim 56 words
A high-altitude, high-voltage electrical connector lead assembly as set forth in claim 1, wherein said assembly additionally comprises a resilient O-ring surroundingly engaging said insulated electrical lead and located between said flexible cap and said cylindrical bushing, whereby upon assembly, said O-ring will be axially compressed and radially expanded so as to provide a fluid-tight seal.
Claim 6
Dependent Claim 25 words
A high-altitude, high-voltage electrical connector lead assembly as set forth in claim 4, wherein said resilient O-ring is movably disposed upon said insulated electrical lead.
Claim 7
Dependent Claim 25 words
A high-altitude, high-voltage electrical connector lead assembly as set forth in claim 4, wherein said resilient O-ring is integrally molded with said insulated electrical lead.
