Claim Text:
1. A universal serial bus (USB) connector comprising: a case having a front end, a middle end, and a rear end, the front end defining an inlet hole; an insulation tongue located at the middle of the inlet hole of the case, wherein a front end of the insulation tongue has an upper side and a lower side that are each cambered; a plurality of electric conduction bars installed on the insulation tongue, and spaced in a horizontal direction of the insulation tongue; a resilient supporting pole connected between a rear end of the insulation tongue and the case; and a first row of electric coupling pins located above the installation tongue, and a second row of electric coupling pins located below the insulation tongue; wherein each of the plurality of electric conduction bars have a top surface and a bottom surface, respectively, exposed out of an upper surface and a lower surface of the insulation tongue, the top surface of each electric conduction bar faces a corresponding one of the electric coupling pins above the insulation tongue, and the bottom surface of each electric conduction bar faces a corresponding one of the electric coupling pins locating below the insulation tongue, the electric coupling pins locating above the insulation tongue and the electric coupling pins locating below the insulation tongue are reversely and symmetrically arranged by type, each electric coupling pin locating above the insulation tongue is electrically coupled to the corresponding type of electric coupling pin locating below the insulation tongue, and the insulation tongue is movable along a vertical direction by deforming the resilient supporting pole.
