Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a schematic structural view of an electric-shock-proof single-phase socket according to Embodiment 1 of the present utility model.

Fig. 2 is a schematic structural diagram of an electric-shock-proof single-phase socket according to Embodiment 4 of the present utility model.

[detailed description]

The structure of the anti-shock single-phase socket of Embodiment 1 of the utility model is shown in Figure 1, including a housing 1, a clip power-off mechanism installed inside the housing 1 and two metal clips 2A and 2B. Two jacks 101 are arranged on the top plate of the.

The clip power-off mechanism includes a ferromagnet 3 and a power-off switch, and the power-off switch includes a lever 4, a coil spring 8 and a normally open power-off contact. The material of the ferromagnetic body 3 is soft iron.

The middle part of the lever 4 is hinged with the hinge shaft 102 of the housing 1 , and the ferromagnet 3 is fixed on the right end of the lever 4 .

The arrangement of the lever 4 makes the ferromagnetic body 3 close to the top plate of the housing 1 , between the two sockets 101 .

The metal clip 2A is fixed on the housing 1, and the movable contact 5A of the power-off contact is fixed on the left end of the lever 4, and is electrically connected with the metal clip 2A. The metal clip 2B is fixed on the housing 1 and is electrically connected to the neutral wire 7 of the socket.

The fixed contact 5B of the power-off contact is fixed on the housing 1 and is electrically connected with the live wire 6 of the socket.

The coil spring 8 is arranged at one end of the movable contact of the lever 4, and the elastic force of the coil spring 8 separates the movable contact 5A from the fixed contact 5B.

The anti-shock single-phase socket of Embodiment 1 of the utility model needs to be used in conjunction with a plug with a permanent magnet. As shown in FIG. The bottom of the body 101 is located between the two pins 102 .

When the anti-shock single-phase socket of Embodiment 1 of the utility model is not inserted with a plug, because the movable contact of the power-off contact is not closed with the fixed contact, the metal clip of the socket has no electricity, which is safe for children and blind people.
