Abstract
Abstract Wire seals in the form of tubular seal members having outer and inner surfaces in pressure sealing engagement with inner surfaces of passages in a dielectric support member and with outer surfaces of the insulating coverings of wires connected to contacts in the passages. Preferably, the pressure sealing engagements are established upon axial movement of the seal members into the passages and interlocking means are provided to retain the seal members in the passages, the seal members however being removable for servicing of wires and contacts. Important features relate to the materials used to permit operation under extremes of environmental conditions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
In an electrical connector, a support member having an end face and a plurality of passages therein extending generally in parallel relation normal to said end face, an electrical contact in each of said passages adapted to be connected to a conductor having an insulating covering thereon, said support member being formed with an inwardly facing annular shoulder in each of said passages, a tubular seal of resilient material for surrounding said conductors and said insulating coverings thereof and arranged to be moved therealong inwardly into said passages, said seal members having outwardly facing annular shoulders engageable with said inwardly facing annular shoulders in said passages of said support member to retain said seal members in said passages, each of said passages including a tapered section of generally frustoconical shape disposed inwardly with respect to said shoulder thereof and arranged to wedge said seal member into pressure engagement with said insulating covering upon insertion of said seal member into said passage, said shoulders having dimensions such as to permit withdrawal of each seal member independently of the other seal members for servicing of said conductors and contacts.
Claim 2
Dependent Claim
187 words
In an electrical connector, a support member having an end face and a plurality of passages therein extending generally in parallel relation normal to said end face, an electrical contact in each of said passages adapted to be connected to a conductor having an insulating covering thereon, said support member being formed with an inwardly facing annular shoulder in each of said passages, a tubular seal of resilient material for surrounding said conductors and said insulating coverings thereof and arranged to be moved therealong inwardly into said passages, said seal members having outwardly facing annular shoulders engageable with said inwardly facing annular shoulders in said passages of said support member to retain said seal members in said passages, each of said passages including a tapered section of generally frustoconical shape disposed inwardly with respect to said shoulder thereof and arranged to wedge said seal member into pressure engagement with said insulating covering upon insertion of said seal member into said passage, said shoulders having dimensions such as to permit withdrawal of each seal member independently of the other seal members for servicing of said conductors and contacts.
Claim 3
Dependent Claim
35 words
In an electrical connector as defined in claim 1, each of said tubular seal members having an enlarged head portion for engaging said end face of said support member when said annular shoulders are interengaged.
Claim 4
Dependent Claim
20 words
In an electrical connector as defined in claim 1, said support member and said seal members being of semihard materials.
Claim 5
Dependent Claim
35 words
In an electrical connector as defined in claim 3, the modulus of elasticity of the semihard materials of said support member and said seal members being on the order of 300,000 pounds per square inch.
Claim 6
Dependent Claim
46 words
In an electrical connector as defined in claim 4, said support member being of a polymer material having a basic polymer structure consisting of phenyl and biphenyl units linked by oxygen and sulfone groups, and said tubular seal members and said insulating coverings being of Teflon.
