Abstract
Abstract An electrical connector is disclosed for interconnection to a printed circuit board having signal traces and ground circuitry thereon. The connector includes signal contacts for termination to the signal traces on the printed circuit board. A conductive housing has receptacles, including insulators, for mounting the signal contacts therein. A plurality of ground projections are formed integral with the housing for interconnection to the ground circuitry on the printed circuit board.
