Abstract: A connection plug for a portable terminal includes a plurality of plug connection terminals of different types disposed on one plane in a case and connected with socket connection terminals mounted to a socket. Here, ends of the plurality of plug connection terminals to be connected with the socket connection terminals are disposed in different positions. The plurality of plug connection terminals are in different lengths. Accordingly, since different types of plug connection terminals of the connection plug are mounted on one plane such that the ends of the plug connection terminals are disposed in different positions, thickness of the connection plug may be minimized. Also, different functions may be performed with one connection plug. In addition, since different plug connection terminals are in different lengths, connection between the respective connection terminals may be stably achieved when the connection plug is inserted in the socket.

Abstract: A connection socket for a portable terminal includes a plurality of connection terminals of different types disposed in different positions on one plane in a case and connected with plug connection terminals mounted to a connection plug. Here, portions of the plurality of connection terminals to be connected with the plug connection terminals are disposed in different positions. The plurality of connection terminals are in different lengths.
