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.

Dependent claims

An electric socket, comprising:

a base provided with a plurality of electrodes and conduction members beside said electrodes, wherein each of said conduction members is connected to a power source and keeps a predetermined distance away from said electrode in a normal condition;
an upper casing having a plurality of apertures corresponding to said electrodes respectively;
a power control unit including a control block beside said conduction members, wherein said control block is moved to bend said conduction members toward said electrodes and makes said conduction members contacting said electrodes respectively;
and
a plurality of shutter members pivoted on said base and a spring, wherein each of said shutter members is under said apertures of said upper casing to shut said apertures and may be moved away from said apertures, and said spring urges said shutter members to positions of shutting said apertures;
wherein said power control unit includes a protrusion in association with said shutter member that said power control unit is stopped by said shutter member when said shutter member is located at the position of shutting said aperture, and said power control unit is free to be moved only when said shutter member is moved away from said aperture.
