PURPOSE: A portable terminal is provided to control angles between a socket and a plug by enabling the plug to selectively combine with the socket. CONSTITUTION: A socket(156) is arranged at one side of a body unit. A plug selectively combines with the socket. A rotation restriction unit is arranged on the socket or the plug. The rotation restriction unit is projected from one side to other side in order to restrict rotation angles of the plug combined with the socket. The rotation restriction unit is a rib which is projected from the outside plug.
