ABSTRACT:
A connector comprises a socket adapted to be mounted in a potable radiotelephone having an internal power supply and a plug having a power code for supplying electric power from an external power supply to the radiotelephone. The socket has a pair of input terminals, movable and stationary terminals. The movable terminal is formed with a pair of torsion members each of which has a contact. The contacts are urged to the stationary terminal to make a first electrical connection therebetween for allowing a first operation of the radiotelephone with the use of the internal power supply. For preventing an accidental breakage of the first electrical connection which is caused by dust or pieces of thread put between the movable and stationary terminals, a contact-point between one of the contacts and the stationary terminal is displaced from that between the other contact and the stationary terminal in an inserting direction of the plug into the socket. When the plug is connected to the socket, output terminals of the plug are connected to the input terminals to make a second electrical connection therebetween for allowing a second operation of the radiotelephone with the use of the external power supply, and at the same time the first electrical connection can be broken. As a result, it is possible to switch the first operation of the radiotelephone to the second operation thereof by connecting the plug to the socket.
