<p>Disclosed herein is a two-way plug which can be inserted into a connection port regardless of the orientation of the plug. The two-way plug includes a rectangular frame, a hard substrate and four connection terminals. The rectangular frame is inserted into a connection port such that the rectangular frame is supported by the connection port. The substrate is disposed in a central portion of the rectangular frame. The four connection terminals are formed on each of the two surfaces of the substrate to form a symmetrical structure. Regardless of the orientation of the rectangular frame inserted into the connection port, the four connection terminals formed on one surface of the substrate are each connected to one of four connection pins provided in the connection port, and the four connection terminals formed on the other surface of the substrate are prevented from coming into contact with a tension pin provided in the connection port.</p> |
