Abstract
Abstract An EMI/RFI shield is disclosed in which the shield is mounted in a continuous groove (38) formed about the outside surface of the connector plug (12).The shield comprises a metal spring (46) which is mounted over the outside of an elastomeric backup ring (48). Marginal portions (66) of the spring (46) are wrapped around the side edges (56,58) of the ring (48) so that the spring (46) will wipe along sidewalls (70) of the groove (38) when the plug (12) is mated with the receptacle (14), thereby enhancing the electrical connection between the plug (12) and receptacle shells (16), and increasing shielding effectiveness.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
An electrical connector comprising: first and second mating connector members having spaced peripheral surfaces thereon facing each other when said connector members are mated, said peripheral surfaces surrounding the center axis of said connector members; a continuous groove formed about one of said peripheral surfaces, said groove having a bottom and spaced sidewalls; electrical connecting means mounted in said groove, said connecting means comprising a substantially closed loop elastomeric member and a metallic spring; said metallic spring being mounted around the surface of said elastomeric member opposite to said bottom of said groove; said spring having marginal portions extending over the sides of said elastomeric member adjacent to said sidewalls; and said elastomeric member being compressed radially when said connector members are mated causing said spring marginal portions to slidably engage said groove sidewalls.
Claim 2
Dependent Claim
134 words
An electrical connector comprising: first and second mating connector members having spaced peripheral surfaces thereon facing each other when said connector members are mated, said peripheral surfaces surrounding the center axis of said connector members; a continuous groove formed about one of said peripheral surfaces, said groove having a bottom and spaced sidewalls; electrical connecting means mounted in said groove, said connecting means comprising a substantially closed loop elastomeric member and a metallic spring; said metallic spring being mounted around the surface of said elastomeric member opposite to said bottom of said groove; said spring having marginal portions extending over the sides of said elastomeric member adjacent to said sidewalls; and said elastomeric member being compressed radially when said connector members are mated causing said spring marginal portions to slidably engage said groove sidewalls.
Claim 3
Dependent Claim
72 words
An electrical connector as set forth in claim 1 wherein: said first and second connector members comprise a plug and a receptacle each having a shell, said plug shell being slidable into said receptacle shell when said plug and receptacle are mated; said groove is provided in the outer surface of said plug shell; and said metallic spring is mounted over the outer periphery of said elastomeric member mounted in said groove.
Claim 4
Dependent Claim
36 words
An electrical connector as set forth in claim 1 or 2 wherein: said connecting means has an interference fit in said groove causing said spring to be bowed outwardly before said plug and receptacle are mated.
Claim 5
Dependent Claim
50 words
An electrical connector as set forth in any one of claims 1 to 3 wherein: said elastomeric member has a relatively wide outer portion over which said spring is mounted, and a relatively narrow inner portion extending from the marginal portions of said spring to said bottom of said groove.
Claim 6
Dependent Claim
61 words
An electrical connector as set forth in any one of claims 1 to 4 wherein: an upstanding flange is provided on the bottom of said groove between said sidewalls thereof; and a continuous channel is formed about the inner periphery of said inner portion of said elastomeric member into which said flange extends for retaining said elastomeric member in said groove.
Claim 7
Dependent Claim
70 words
An electrical connector as set forth in any one of claims 1 to 5 wherein: a continuous recess is formed in the outer periphery of said outer portion of said elastomeric member about said channel forming a relatively thin section therebetween dimensioned to allow the side portions of said elastomeric member adjacent to said sides thereof to operate substantially independent of each other during mating of said plug and receptacle.
Claim 8
Dependent Claim
39 words
An electrical connector as set forth in any one of claims 1 to 6 wherein: said elastomeric member carries said spring and is shaped to undergo greater resilient deflection than said spring when said plug and receptacle are mated.
