Abstract
Abstract Mating forward ends (14, 24) of a receptacle connector (10) mounted in a panel (18) and plug connector (20) carrying a coupling member (30, 34, 40) are protected by a moisture seal (60) when interconnected. The moisture seal comprises a tubular body portion (64) which squeezes about the coupling member and a cup portion (66) which collapsibly compresses about the panel mounted connector, tubular body (64) including an annular shoulder (62) sized to be received in an annular cavity (50) around a sleeve (40) of the coupling member. The cup (64) comprises a frust-conical skirt (68), an annular collar (67) connecting the skirt to the body (64) and an annular foot (69) for sealing about the panel (18), reduced thicknesses (71, 73, 74) of tubular body portion (64) and annular collar (67) allowing cup portion (64) to collapse rearwardly relative to the coupling member when the annular foot (69) is forced against the panel (18).

Claim 1
Independent Claim
310 words
A releasing electrical connector having a moisture seal, the releasing electrical connector including a pair of connector members (10, 20) with each having, respectively, a forward end portion (14, 24), a duality of electrical contacts (11, 21) carried by said connector members and forming an electrical interconnection, and means (30, 34, 40, 39, 37, 17) for releasably coupling the connector members, one of the connector members (10) being mounted in a panel (18) and having its forward end portion (14) extending therefrom and mated with the forward end portion (24) of the other connector member (20), the releasable coupling means including an operating sleeve (40) disposed about the mated end portions (14, 24), said moisture seal characterized by: said operating sleeve (40) having an annular cavity (50) disposed in the outer surface thereof; and a resilient seal member (60) including a tubular portion (66), a collapsible cup portion (64), and a hinge-like connection therebetween defined by each said portion having an end portion (71, 73) of reduced thickness being connected together, said cup portion including a foot portion (67) having a substantially flat forward end face (61) and said cup portion being disposed around the mated end portions (14, 24) such that said forward end face (61) thereof is compressed against the panel (18), said tubular portion (66) being arranged snugly about the forward end portion of the operating sleeve (40) and having a radially inwardly directed annular shoulder (62) disposed within said annular cavity (50) in said operating sleeve (40), said foot portion (67) further having a chamfered end face (63) extending from said flat end face (61) with said end faces (61, 63) being adapted to flatten against the panel (18), said connector members being coupled together causing the cup (64) to collapse about the panel (18) and the second end face (63) to flatten against the panel.
Claim 2
Dependent Claim
310 words
A releasing electrical connector having a moisture seal, the releasing electrical connector including a pair of connector members (10, 20) with each having, respectively, a forward end portion (14, 24), a duality of electrical contacts (11, 21) carried by said connector members and forming an electrical interconnection, and means (30, 34, 40, 39, 37, 17) for releasably coupling the connector members, one of the connector members (10) being mounted in a panel (18) and having its forward end portion (14) extending therefrom and mated with the forward end portion (24) of the other connector member (20), the releasable coupling means including an operating sleeve (40) disposed about the mated end portions (14, 24), said moisture seal characterized by: said operating sleeve (40) having an annular cavity (50) disposed in the outer surface thereof; and a resilient seal member (60) including a tubular portion (66), a collapsible cup portion (64), and a hinge-like connection therebetween defined by each said portion having an end portion (71, 73) of reduced thickness being connected together, said cup portion including a foot portion (67) having a substantially flat forward end face (61) and said cup portion being disposed around the mated end portions (14, 24) such that said forward end face (61) thereof is compressed against the panel (18), said tubular portion (66) being arranged snugly about the forward end portion of the operating sleeve (40) and having a radially inwardly directed annular shoulder (62) disposed within said annular cavity (50) in said operating sleeve (40), said foot portion (67) further having a chamfered end face (63) extending from said flat end face (61) with said end faces (61, 63) being adapted to flatten against the panel (18), said connector members being coupled together causing the cup (64) to collapse about the panel (18) and the second end face (63) to flatten against the panel.
Claim 3
Dependent Claim
22 words
The releasing electrical connector as recited in claim 1 wherein seal member (60) is integrally molded into one-piece from an acellular elastomer.
Claim 4
Dependent Claim
104 words
The releasing electrical connector as recited in claim 1 wherein said cup portion (64) is a frusto-conical shape and includes a skirt (68) having an annular collar (67) connected thereto, said annular collar (67) having remote from its connection to said skirt (68) one said end portion (73) of reduced thickness and said tubular portion (66) includes the other said end portion (71) of reduced thickness at a location remote from its annular shoulder (62), said end portions (71, 73) being connected together to form a radial cut-out (74) and define said hinge-like connection between said cup portion (64) and said tubular portion (66).
Claim 5
Dependent Claim
21 words
The releasing electrical connector as recited in claim 3 wherein said foot (67) is extending radially outwardly from the skirt (68).
Claim 6
Dependent Claim
