Abstract
An electric socket with locking means inside; when the plug is inserted into it, the electrical source will be connected, and at the same time, the plug will be locked. To disconnect the plug, a button must first be pushed to release the locking means and disconnect the electrical source. This construction will be very safe because there is no way to contact the electrical source from the socket either with the plug inserted or without the plug inserted. When it is connected, accidental disengagement of the plug and disconnection of the electrical source will not occur.
