Abstract
Abstract A conductive elastomeric element electronic connector assembly in which a plurality of conductive elastomeric connector elements are held in openings in a connector element carrier positioned between a pair of spaced substrates having contact pads which are to be connected together electrically. Each connector element has a volume within the confines of the opening in which it is held which is less than the volume of the opening, so that upon axial compression of the connector element, which occurs as the substrates are brought together to establish contact between the contact pads and the ends of the connector elements, the connector elements can deflect and expand into the extra space in the openings in which they are held.
