Abstract
Abstract A high density electrical connector for use between semiconductor module boards. The connector has a rigid member and a flexible member connected to it, which provides elastomeric contact pressure. The rigid and flexible members are embodied in a dual durometer rubber layer having a relatively high durometer layer for the rigid member and a relatively low durometer layer for the flexible member. The relatively low durometer layer has circuit connector leads disposed thereon on the side facing away from the relatively high durometer layer. During the positioning of the electrical conductor into the relatively low durometer layer by pressing against a circuit board, a wiping action occurs to clean dust particles and other contaminants from the connector surface prior to forming an electrically conductive bond thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
A device for electrically connecting two spaced apart lands comprising: (a) a relatively rigid member; (b) a compressible member operatively connected to said relatively rigid member along a bond line therebetween, said compressible member having a cavity for receiving a wire; (c) an electrically conductive wire having an irregularly shaped cross-section having an acute protuberance shaped thereon, said protuberance being operatively connected to at least a portion of said bond line and said wire being seated in a first portion in said cavity and extending therefrom; and (d) two lands adjacent one another and adapted to move relative to said wire so that when said relatively rigid member is forced generally towards said lands, said wire is pivoted into contact with both of said lands in a wiping action to form an electrically conductive connection therebetween.
Claim 2
Independent Claim
136 words
A device for electrically connecting two spaced apart lands comprising: (a) a relatively rigid member; (b) a compressible member operatively connected to said relatively rigid member along a bond line therebetween, said compressible member having a cavity for receiving a wire; (c) an electrically conductive wire having an irregularly shaped cross-section having an acute protuberance shaped thereon, said protuberance being operatively connected to at least a portion of said bond line and said wire being seated in a first portion in said cavity and extending therefrom; and (d) two lands adjacent one another and adapted to move relative to said wire so that when said relatively rigid member is forced generally towards said lands, said wire is pivoted into contact with both of said lands in a wiping action to form an electrically conductive connection therebetween.
Claim 3
Dependent Claim
20 words
The device in accordance with claim 1 wherein said wiping activity of said portion of said lands removes contaminants therefrom.
Claim 4
Independent Claim
135 words
A method for manufacturing a connector body adapted to complete an electrical circuit that includes lands on first and second circuit boards, the steps comprising: (a) extruding a connector body consisting of a first layer of relatively high stiffness and a second layer of relatively resilient material bonded thereto, during which extruding step conductive wires are bonded to said resilient layer with said wires being exposed on a lower side of said resilient layer which is opposite to the upper side thereof on which said first layer is bonded; and (b) cutting the extruded body to a predetermined length to produce a connector body which can be pressed downwardly against said circuit boards to connect lands electrically on said first circuit board to lands on said second circuit board by means of said conductive wires.
Claim 5
Independent Claim
135 words
A method for manufacturing a connector body adapted to complete an electrical circuit that includes lands on first and second circuit boards, the steps comprising: (a) extruding a connector body consisting of a first layer of relatively high stiffness and a second layer of relatively resilient material bonded thereto, during which extruding step conductive wires are bonded to said resilient layer with said wires being exposed on a lower side of said resilient layer which is opposite to the upper side thereof on which said first layer is bonded; and (b) cutting the extruded body to a predetermined length to produce a connector body which can be pressed downwardly against said circuit boards to connect lands electrically on said first circuit board to lands on said second circuit board by means of said conductive wires.
Claim 6
Dependent Claim
12 words
The method in accordance with claim 3 wherein said wires are copper.
Claim 7
Dependent Claim
26 words
The method in accordance with claim 4, the steps further comprising: (c) plating said wires with a non-oxiding material prior to bonding said resilient layer thereto.
Claim 8
Dependent Claim
13 words
The method in accordance with claim 5 wherein said non-oxiding material is gold.
Claim 9
Dependent Claim
14 words
The method in accordance with claim 5 wherein said non-oxiding material is phosphor bronze.
