An electrical connector includes a terminal module including an insulating housing, a plurality of terminals and a shielding plate. The insulating housing defines a base and a mating tongue extending from the base, the mating tongue defines opposite mating surfaces, a front face and opposite side faces connecting with the mating surfaces and the front face. The terminals include contacting sections exposed upon the mating surfaces and leg sections out of the base. The shielding plate is embedded in the insulating housing and includes a main portion disposed between the mating surfaces and two thickened side portions, the side portions enclose opposite side faces of the mating tongue and each provides a side latch at an outer side face thereof. The side portions extend forward to the front face of the mating tongue and rearward to the base.
