| 20110136381 | BIDIRECTIONAL PLUG HAVING SHORT CIRCUIT PREVENTION CIRCUIT - Disclosed herein is a bidirectional plug having a short circuit prevention circuit. The bidirectional plug includes a body part, a terminal part, connecting terminals, and a short circuit prevention circuit. The terminal part is connected to one end of the body part, and is inserted into an interface port of a communication device. The connecting terminals are respectively provided on two opposite surfaces of the terminal part, and make contact with a connecting pin provided in the interface port regardless of a direction from which the terminal part is inserted. The short circuit prevention circuit prevents a remaining connecting terminal, provided on a surface of the terminal part which is not in contact with a connecting pin, from making electrical contact with a tension ground pin provided in the interface port. | 06-09-2011 |
