ABSTRACT:
A universal series bus (USB) has a grille-like top frame, a bottom frame and a circuit board mounted between the top frame and the bottom frame. Both the top and bottom frames are defined with multiple corresponding slots, and accordingly a rib is formed between each two adjacent slots. The circuit board has a top side and a bottom side, wherein USB contacts are formed on both sides and correspond to the slots. Therefore, when the USB plug is inserted into a standard USB port, the USB contacts formed on one side correspondingly touch the conductive pins. On the other side of the USB plug, since the protruding ribs abut against resilient metal tongues inside the USB port, the contacts on the other side will not touch to the metal tongues thus avoiding the occurrence of short circuit.
