  • Publication number: 20090156066
    Abstract: An electric socket includes a base provided with two electrodes and conduction members beside the electrodes. Each of the conduction members is connected to a power source and keeps a predetermined distance away from the electrodes. An upper casing has two apertures corresponding to the electrodes respectively. A power control unit includes a control block beside the conduction members and a control shaft having an end connected to the control block and an opposite end extended out of the upper casing. Two shutter members are pivoted on the base to shut the aperture. When a plug is inserted into the electric socket of the present invention, prongs of the slug will move away the shutter first, and then press the control shaft to make the control block bending the conduction members toward the electrodes that makes the conduction members contacting the electrodes respectively.
