Abstract
Abstract Disclosed is an electrical connector composed of a dielectric housing that defines an internal cavity, cable openings for receiving the ends of a pair of flat ribbon cables with alternating ground and signal wires, and conductor openings for receiving conductor elements to be connected to the conductive wires in the flat cables. Located in the cavity is a first grounding bus for electrically connecting together the alternate ground wires in one of the cables and a second grounding bus for electrically connecting together the alternate ground wires in the other cable. Also retained within the cavity are a plurality of electrically isolated coupling elements each operative to electrically connect one of the conductor elements with a different one of the alternate signal wires in the two cables. Finally a ground output means connects the first and second grounding busses to at least one conductor element so as to connect all of the ground wires to a circuit common outside the connector.
