An electrical connector includes an insulating housing having a front frame and a rear frame engaged with the front frame. The front frame defines at least two receiving grooves at a top portion and a bottom portion thereof respectively. The rear frame defines at least one fixing groove passing through a front portion thereof. At least one latch member has a hollowed bearing portion extending from both distal ends thereof to form two resilient arms. The bearing portion and the resilient arms are received in the fixing groove of the rear frame. A tip end of each resilient arm extending into the corresponding receiving groove protrudes to form a limiting portion which is exposed out of the receiving groove of the front frame, and a plurality of terminals is disposed in the insulating housing respectively.
