Abstract
An electrical connector for interconnecting a first circuit such as an integrated circuit having a plurality of IC terminals with a second circuit having a plurality of contact pads when the terminals and pads are positioned opposite each other. The connector includes an electrically insulating sheet made of a first elastic material formed with a plurality of bores extending therethrough in a direction mutually perpendicular to the first and second circuits, and a plurality of electrical conductors, each made of a second, electrically conductive elastic material and shaped so as to contact the first circuit terminals. The elastic material electrical conductors are each positioned relative to the electrically insulating sheet so as to cover each of the bores and extend into the bore co-axially therewith. The elastic conductors are sized to extend into the bores a distance insufficient to contact the second circuit pads when the insulating elastic sheet is uncompressed, and sufficient to contact the second circuit pads when the elastic insulating sheet is compressed, thereby, upon compression of the sheet to complete an electric connection between the first circuit terminals and the second circuit pads.
