Patent ID: 6951467

Claim:
A conductive fastening structure suitable for connecting first and second conducting surfaces of a circuit board through an aperture in the board comprising: a conical structure having an annular member with a plurality of circumferentially placed projections extending outward form the annular member, a segmented disc attached at its periphery to the inner surface of the annular member, the segmented disc formed so as to define an aperture coaxially aligned with the axis of the annular member and located on a plane spaced from the plane of the annular member on the side of the annular member opposite the circumferentially placed projections; an insulating washer adapted to fit within the conical structure the washer having an aperture complimentary to the aperture in the circuit board, and adapted to fit within the circumferential projections of the conical structure; an insulating sleeve complimentary to the aperture in the board the sleeve having a head on one end to hold the insulating sleeve in place and provide an insulating surface on the side of the circuit board opposite the insulating washer; a tubular T-shaped rivet having a head and a leg with a second plurality of circumferentially extending projections extending there-from the second plurality of projections extending in the direction and being coaxially aligned with the leg of the T-shaped rivet, the leg of the T-shaped rivet being complimentary to the aperture defined by the segmented disc so as to grip the leg when the leg is forced into the aperture.
