Abstract
Abstract An electrically conductive elastomer gasket that is reinforced to lend strength to the gasket and enable the gasket to have the ability to hold a pre-set shape. This is accomplished by either sandwiching an electrically conductive reinforcement metal layer between two electrically conductive elastomer outer layers or by providing an electrical conductor about which an electrically conductive elastomer is formed or extruded.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
99 words
An electrically conductive gasket for an electromagnetic enclosure; said gasket comprising an elastomeric material containing conductive particles and an electrically conducting reinforcement in the form of a single wire in communication with said conductive particles and located in the center of said elastomeric material, said reinforcement being interconnected forming a closed loop, said reinforcement having means thereon to restrict plastic flow of the elastomeric material and electrically interconnect said reinforcement and said conductive particles, and said elastomeric material having a generally circular outer surface and being mounted about said reinforcement with said reinforcement giving body support to the gasket.
Claim 2
Dependent Claim
99 words
An electrically conductive gasket for an electromagnetic enclosure; said gasket comprising an elastomeric material containing conductive particles and an electrically conducting reinforcement in the form of a single wire in communication with said conductive particles and located in the center of said elastomeric material, said reinforcement being interconnected forming a closed loop, said reinforcement having means thereon to restrict plastic flow of the elastomeric material and electrically interconnect said reinforcement and said conductive particles, and said elastomeric material having a generally circular outer surface and being mounted about said reinforcement with said reinforcement giving body support to the gasket.
Claim 3
Dependent Claim
33 words
An electrically conductive gasket as Set forth in claim 1, wherein said means includes projections on said reinforcement in the form of bumps or barbs and said elastomeric material completely encloses said reinforcement.
