Abstract (en)
An electrical connector for a cordless electrical appliance includes a plug and a socket that are interconnectable and relatively rotatable; in the center of the plug's upper face there is a plughole and a number of ring grooves being concentric with the plughole, with power supply terminal lugs inside them respectively. Correspondingly, the plug is provided with receiving center terminal lugs and periphery terminal lugs that are respectively engaged with the power supply terminal lugs inside the center plughole and the ring grooves of the plug. The Socket is characterized by that it also includes at least one power supply contact sheet connected with live wire or zero line of power supply and at least one contact switching mechanism, which keeps the contacts between the power supply contact sheet and the corresponding receiving terminal lugs normally open when the plug isn't inserted into the socket, and makes the normally open contact pair close and electrify under the action of the plug when the plug is inserted into the socket. In this invention, because the visible power supply contact sheet of the socket surface is not electrified all the time, the electrical connector is not only ensured safety in use, but also facilitated for connecting on account of the unrestricted width and depth of the grooves. <IMAGE>
