US 2006/0040549 A1 · USB PLUG WITH TWO SIDES ALTERNATELY CONNECTABLE TO A USB PORT

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.

Dependent claims

A USB plug with two sides alternately connectable to a USB port, the USB plug comprising:

a top frame formed by a rectangular body in which first slots are defined through the body and multiple first ribs are formed among the first slots, wherein each first rib is formed between two adjacent first slots;
a bottom frame formed by a rectangular body in which second slots are defined through the body and correspond to first slots of the top frame and multiple second ribs are formed among the second slots, wherein each second rib is formed between two adjacent second slots;
and
a circuit board mounted between the top frame and the bottom frame, wherein the circuit board has a top side and a bottom side, four standard USB contacts are formed on both the top side and the bottom side near a front end of the circuit board to exactly correspond to the first and second slots;
wherein the circuit board is constructed from multiple circuit layers, the top layer and bottom layer form the USB contacts, the intervening layers provide a ground plate and an operating voltage.
