The present case adopts the contact design, rather than adopting the jack design for the socket upside is a closed surface, has very good water-proof effects, also avoids child to take the electric shock accident that metal inserted the jack and lead to. In addition, the live wire and the zero line are separated by the ground wire, so that the ground wire can be used for conducting electricity in case of electric shock of people, and safety accidents are avoided.
Furthermore, the three power contacts are lower than the heights of the first positioning groove and the second positioning groove, and are designed to sink. And an annular insulating ring 18 is arranged around the power supply contact to protect the contact. If the power supply contact is flat, even higher than the socket body, a child easily takes the magnet to adsorb the contact and is easy to cause danger.

The first metal connecting plate, the second metal connecting plate, the third metal connecting plate and the fourth metal connecting plate are arranged instead of the metal elastic sheet directly contacting with power contacts (a live wire contact and a zero wire contact), so that the safety accident caused by mistaken adsorption of the metal elastic sheet due to the fact that a child uses a magnet to attach the live wire contact and the zero wire contact is prevented, and the probability of triggering the live wire and the zero wire is small but can not be ignored due to the fact that the scheme is single-point adsorption.
Further, the third metal connecting plate is in contact with the socket body through the central fixing block 142.
In this embodiment, the first metal connecting plate and the second metal connecting plate have the same structure, see fig. 4. The first metal connecting plate 151 comprises a horizontal pressing plate 1511, the left side and the right side of the horizontal pressing plate are respectively provided with a left inclined plate 1512 and a right inclined plate 1514, the left inclined plate is connected with a left horizontal plate 1513, and the left horizontal plate is positioned right above a first contact of a live wire; the right sloping plate is connected with right horizontal plate 1515, right horizontal plate is directly over two contacts of live wire.

And the length of the zero line matching column and the live line matching column extending out of the strong magnetic plate is greater than the depth of a live line contact and a zero line contact. Because of the power contact of the socket is fixed, the elastic movement of the zero line matching column and the live line matching column can ensure that the plug and the socket are better attached under the action of strong magnetism.
