A plug connector assembly for mating with a complementary connector includes a printed circuit board (PCB) defining a plurality of conductive pads, a pair of metal members mounted on two sides of the PCB and soldered with the PCB for electrically connecting with the complementary connector, an inserting member electrically connected on a front end of the PCB to connect to the complementary connector, and a housing enclosing the PCB. The PCB includes a front portion, an opposite rear portion, and a middle portion connecting the front portion and the rear portion. The conductive pads include a plurality of first pads disposed on the front portion. The inserting member includes an insulative member and a plurality of terminals held on the insulative member. The terminals are soldered with corresponding first pads.
