A battery connector has an insulating housing, a plurality of terminals mounted to the insulating housing, and a supporting member fixing the insulating housing on the PCB. The insulating housing has a rectangular base, a recess formed at a rear of the base for receiving the supporting member. The recess has a first recess and a pair of second recesses extended downward from two opposite ends of the first recess. The supporting member has a horizontal beam accommodated in the first recess, a pair of connecting slices extended downwards from ends of the horizontal beam and accommodated in the second recesses, a pair of fixing slices extended downward from a bottom of each connecting slice. Free ends of the fixing slices are protruded opposite to each other to form protrusions inserted into the PCB for fixing the battery connector firmly on the printed circuit board.
