A cable connector comprising a connector, a cable, a circuit board electrically connecting the connector to the cable, an insulating inner housing and an outer housing. The connector comprises an insulating housing, a plurality of conductive terminals disposed therein and a metal shield mounted on the periphery of the insulating housing. The insulating inner housing comprises upper and lower casings integrally coupled together and a receiving space formed therebetween for accommodating the circuit board. The cable connector comprises a copper foil which covers the periphery of the insulating inner housing. The copper foil is electrically coupled to the metal shield and grounded through the metal shield. Finally, the outer housing envelopes the periphery of the copper foil. Thereby, the cable connector can achieve both miniaturized and a lower cost, while also reducing the rate of defective products.
