Referring to fig. 1 and 2, the present embodiment provides a safety socket, which includes a socket body 100, a conductive block 200 and an elastic latch.

The socket body 100 has a receptacle 110 formed on an upper surface thereof, and a first groove 111 formed on a sidewall of the receptacle 110. The elastic bolt comprises an elastic sheet 310, a lug 320 and an electric connector 330; the first end of the elastic piece 310 is fixedly arranged on the upper wall of the first groove 111, the second end of the elastic piece 310 is a free end extending downwards, and the projection 320 is arranged on one side of the elastic piece 310 facing the insertion hole 110; the electric connector 330 is arranged at the bottom of the first groove 111, and the electric connector 330 is electrically connected with a power supply; the elastic piece 310 is electrically connected with the conductive block 200; the bump 320 is an insulator; one end of the conductive block 200 is fixedly disposed on a sidewall of the insertion hole 110, and the other end of the conductive block 200 is disposed in the insertion hole 110 for electrically connecting with the plug 600.

In the above-mentioned structure, before the plug 600 is inserted into the jack 110, the second end of the elastic piece 310 and the electrical connector 330 are not contacted; after inserting the plug 600 into the socket 110, the plug 600 can push the protrusion 320 to make the second end of the elastic piece 310 contact the electrical connector 330; after the plug 600 is pulled out of the jack 110, the second end of the elastic piece 310 is separated from the electrical connector 330 again.

On the basis of the above embodiments, as shown in fig. 1 and 2, the protrusion 320 and/or the conductive block 200 may optionally be in an arc shape protruding toward the center of the insertion hole 110.

The working principle and the operation method of the safety socket of the embodiment are as follows:

first, before use, since the protrusion 320 in the insertion hole 110 is not pushed, the second end of the elastic piece 310 and the electrical connector 330 are in an off state, that is, not connected to a power source, and the whole socket is in a safe state.

Secondly, when children hold conductors such as iron nails, iron sheets or iron wires and insert into the jack 110, the structures of the iron nails, the iron sheets or the iron wires and the plug 600 are different, even if the three conductors are connected with the conductive block 200 in the jack 110, the protrusion 320 is not easily pushed to further promote the contact between the second end of the elastic sheet 310 and the electric connector 330, so that the socket is still in a disconnected state with the power supply, and the danger of electric leakage can still be avoided.

Thirdly, when a child inserts a conductor such as a nail, an iron sheet, or an iron wire into the insertion hole 110, the structure of the nail, the iron sheet, or the iron wire is different from that of the plug 600, and even if the three conductors push the protrusion 320 to further promote the contact between the second end of the elastic piece 310 and the electrical connector 330, the three conductors and the plug 600 have different structures, so that the three conductors cannot generally contact the conductive block 200 connected to the power supply. The risk of electrical leakage can still be avoided.

In a word, only when a conductor with the same structure as the plug 600 is inserted into the jack 110, the bump 320 is pushed to conduct the electrical connector 330 with the power supply, and the conductor is kept in contact with the conductive block 200, so that the electric leakage risk can occur, and therefore, the safety and reliability of power utilization can be greatly improved, and the electric shock casualty accident of children or adults with less common sense of electricity can be avoided.
