Abstract

The utility model relates to a safety socket. The safety socket is provided with metal clamping pieces, clamping-piece elastic clamping mechanisms, transition boards with two sides respectively provided with a first conductive contact chip and a second conductive contact chip and a transition board reset mechanism. Under normal condition (a plug is not plugged), a safety electric clearance is retained between each transition board and an electrically-charged power binding post. When the plug is inserted by the metal clamping pieces and the clamping-piece elastic clamping mechanisms to be connected with the first conductive contact chip, the transition board moves closer to the power binding post only in the case that the insertion force is large enough to overcome the elastic force of the transition board reset mechanism. Then, the second conductive contact chip is contacted with the power binding post, the plug obtains electricity, and the state is maintained by the clamping-piece elastic clamping mechanisms. When a foreign matter is inserted, electric shock will happen only in the same case that the elastic force of the transition board reset mechanism is overcome. When the elastic force is large enough, children electric shock accidents will be avoided.
