A connector includes an electromagnetic shield formed of conductive material with at least two depending, conductive, reinforcement sidewalls that each have a plurality of conductive depending sidewall legs distributed about a periphery of the shield and extending upwardly. The shield includes at least one conductive ground tab extending from an edge such that the shield provides a ground path directly from a circuit board to a connector housing. The shield defines at least one opening for receiving an alignment post and at least one additional rectangular opening to permit access to an electrical terminal positioned below the sheet. The rectangular opening may be aligned with terminals positioned within connector housing.
