Abstract
There is disclosed a wire clamp assembly which includes a screw member and washer or clamping member in mounted relation on the screw member, and adapted to provide a terminal assembly for a terminal block or the like. The washer or clamping member comprises a generally rectangular plate-like washer having a central aperture, engageable by the screw member to be advanced downwardly for clamping a wire or wires against the surface of a terminal member. The surface of the washer member facing the terminal member surface includes two pairs of opposed ramps spaced apart from the central aperture and extending downwardly and diverging outwardly toward the outer periphery of the washer member. The same or undersurface of the washer further includes downwardly sloping corners defining sloping edge portions, for biting engagement with the wire to establish and maintain, together with the ramps, electrical and mechanical connection between the wire and the terminal member.
