Abstract: An electrical connector includes an insulating housing having an erect base body and an erect tongue board, a plurality of conductive terminals of which each has a fastening arm vertically disposed in the base body, a contact arm elastically projecting sideward out of a side face of the tongue board, and a touching arm projecting rearward out from a bottom of the base body, a front shell mounted rearward to the insulating housing with the tongue board and the contact arms being apart located therein, and a rear shell covered to the base body and over the touching arms. The touching arms are horizontally arranged at regular intervals along a transverse direction. The electrical connector is mounted onto the circuit board with the touching arms being elastically against and pressed upward by the circuit board to form electrical connection with the circuit board.
