Abstract
Abstract An electrical connector for engagement preferably with relatively thin conductive material comprising, in one embodiment, a pair of generally planar interengaging members matingly arranged in spaced, opposing relationship. Each of preferably a plurality of preferably tapered piercing members selectively disposed adjacent a first surface of at least one of said members is arranged to penetrate through thin conductive material interposed between said members and extend into and be deformed about an associated selectively proportioned transverse aperture in the mating member as said members are compressively urged against the intervening conductive material, to establish a secure connection therebetween. Each of the members may be provided with one or more extending portions for coupling the connector to a further conductor or support member. Other embodiments include a multiple of spaced, interengaging members similarly comprising selectively disposed transverse apertures and mating piercing members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
285 words
A connection comprising: a connector having at least one first and second members, each having a first surface and a second surface, said first surfaces being arranged in generally spaced, opposing relationship to define an article receiving cavity therebetween; said second member having at least one first transverse aperture therethrough, extending between said first surface and said second surface thereof; a first recessed portion of substantially uniform depth completely surrounding said first transverse aperture adjacent the opening formed by the communication of said first transverse aperture and said second member second surface; a sheet of thin material situated between said first and said second members, and at least one first piercing means disposed adjacent said first member first surface and protruding outwardly therefrom generally normal to the plane thereof, said first piercing means being dimensionally proportioned to fit closely within said first transverse aperture, the height of said first piercing means being greater than the thickness of said second member, said first piercing means terminating in a free end aligned with an associated first transverse aperture , said first and second members being pressed together so that said first surfaces thereof are in intimate contact with said sheet of thin material at least said free end of said first piercing means penetrating said sheet of thin material and expansively laterally deformed within the area of said first recessed portion of said associated first transverse aperture to provide an enlarged head portion thereat seated in said first recessed portion and extending outwardly beyond the area defined by the communication of said associated first transverse aperture and said second member second surface to independently lock said first and said second members together intimately about said thin material.
Claim 2
Dependent Claim
285 words
A connection comprising: a connector having at least one first and second members, each having a first surface and a second surface, said first surfaces being arranged in generally spaced, opposing relationship to define an article receiving cavity therebetween; said second member having at least one first transverse aperture therethrough, extending between said first surface and said second surface thereof; a first recessed portion of substantially uniform depth completely surrounding said first transverse aperture adjacent the opening formed by the communication of said first transverse aperture and said second member second surface; a sheet of thin material situated between said first and said second members, and at least one first piercing means disposed adjacent said first member first surface and protruding outwardly therefrom generally normal to the plane thereof, said first piercing means being dimensionally proportioned to fit closely within said first transverse aperture, the height of said first piercing means being greater than the thickness of said second member, said first piercing means terminating in a free end aligned with an associated first transverse aperture , said first and second members being pressed together so that said first surfaces thereof are in intimate contact with said sheet of thin material at least said free end of said first piercing means penetrating said sheet of thin material and expansively laterally deformed within the area of said first recessed portion of said associated first transverse aperture to provide an enlarged head portion thereat seated in said first recessed portion and extending outwardly beyond the area defined by the communication of said associated first transverse aperture and said second member second surface to independently lock said first and said second members together intimately about said thin material.
Claim 3
Dependent Claim
28 words
A connection as defined in claim 1 wherein said first piercing means comprises a generally tapered member having its larger end disposed adjacent said first member first surface.
Claim 4
Dependent Claim
71 words
A connection as defined in claim 1 further comprising a raised shoulder portion surrounding said first transverse aperture adjacent the opening formed by the communication of said first transverse aperture and said second member first surface, said raised shoulder portion communicating generally with the base of an associated first piercing means upon the closure of said first and said second members, to further entrap a portion of such thin material therebetween.
Claim 5
Dependent Claim
34 words
A connection as defined in claim 1 further comprising an extending portion coupled to at least one of said first and second members for coupling said connector to a further article disposed adjacent thereto.
