USB connector having a tongue with a plurality of contacts on its upper and lower sides symmetrically and reversely arranged

摘要

A universal serial bus (USB) connector includes a case, an insulation tongue, a plurality of spaced electric conduction bars installed to the insulation tongue, a resilient supporting pole connected between the insulation tongue and the case, and two rows of electric coupling pins respectively located above and below the insulation tongue. The electric conduction bars are spaced in a horizontal direction of the insulation tongue. The top surface of each electric conduction bar faces the corresponding electric coupling pin locating above the insulation tongue, and the bottom surface of each electric conduction bar faces the corresponding electric coupling pin 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.
