A cable connector assembly comprises a pair of cables each having two conductive wires, a grounding layer, and an outer jacket. The connector is electrically connected with the cables and has an insulative housing and a number of electrical contacts retained to the insulative housing. The electrical contacts include plural signal contacts electrically connected with the conductive wires, plural grounding contacts, and plural grounding pins backwardly integrally extending from the grounding contacts. The grounding pin is disposed between the outer jacket and the grounding layer to electrically connect with the grounding layer.
