Abstract
Abstract Diaphragm seal for an electrical connector using a material capable of taking a set under compression, the material being used in a manner such that it is effectively subjected only to tensioning, bending and shear to avoid taking a set. In particular, a resilient annular lip is engaged by a rigid annular edge at a point intermediate a root portion and a free edge to urge the free edge into pressure sealing engagement with an annular surface of a member from which the root portion is supported.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
In an electrical connector, first and second members adapted to be connected together, said first member having an annular surface portion and said second member having a rigid annular edge, and a seal member including an annular redially extending resilient lip including a root portion supported from said first member and an annular free edge, said rigid annular edge of said second member being engageable with said lip at a point between said root portion and said free edge to urge said free edge into pressure sealing engagement with said annular surface portion of said first member when said first and second members are connected together, said annular surface portion of said first member being generally cylindrical, and said lip extending angularly from said root portion to said free edge and at an acute angle relative to said generally cylindrical annular surface portion.
Claim 2
Dependent Claim
143 words
In an electrical connector, first and second members adapted to be connected together, said first member having an annular surface portion and said second member having a rigid annular edge, and a seal member including an annular redially extending resilient lip including a root portion supported from said first member and an annular free edge, said rigid annular edge of said second member being engageable with said lip at a point between said root portion and said free edge to urge said free edge into pressure sealing engagement with said annular surface portion of said first member when said first and second members are connected together, said annular surface portion of said first member being generally cylindrical, and said lip extending angularly from said root portion to said free edge and at an acute angle relative to said generally cylindrical annular surface portion.
Claim 3
Dependent Claim
44 words
In an electrical connector as defined in claim 1, said first member having an additional annular surface portion of generally frustoconical shape generally parallel to said lip and on the side of said lip opposite the side thereof engaged by said rigid annular edge.
Claim 4
Dependent Claim
19 words
In an electrical connector as defined in claim 1, said seal member being of a relatively soft rubber material.
Claim 5
Dependent Claim
49 words
In an electrical connector as defined in claim 1, said first and second members having cylindrical surfaces loosely fitted in telescoping relation with predetermined manufacturing tolerances, and said resilient lip being operative to maintain an effective seal irrespective of relative cocking and scooping of said first and second members.
Claim 6
Dependent Claim
70 words
In an electrical connector as defined in claim 1, said first and second members when connected together having faces in spaced facing relation and said seal member having a central portion sandwiched and compressed between said faces when said members are connected together, said root portion of said lip being integral with the periphery of said central portion and said free edge being spaced radially outwardly from said root portion.
Claim 7
Dependent Claim
47 words
In an electrical connector as defined in claim 5, contacts carried by said first and second members and arranged to meet when said members are connected together, said central portion of said seal member having openings for passage of said contacts therethrough and for sealing engagement therewith.
Claim 8
Dependent Claim
66 words
In an electrical connector as defined in claim 1, said first member being in the form of a receptacle and said annular surface portion being a generally cylindrical internal surface, said second member being in the form of a plug and said rigid annular edge being defined by the intersection between an end face of said plug and a generally cylindrical outer surface of said plug.
Claim 9
Dependent Claim
92 words
In an electrical connector as defined in claim 7, said first member having an internal face in spaced facing relation to said end face of said second member when said members are connected together, and said seal member having a central portion sandwiched between said internal face of said first member and said end face of said second member when said members are connected together, said root portion of said lip being integral with the periphery of said central portion with said free edge being spaced radially outwardly from said root portion.
Claim 10
Dependent Claim
37 words
In an electrical connector as defined in claim 8, said seal member having an annular slot at the juncture between said root portion and said periphery of said central portion to increase the flexibility of said lip.
