the power control switch 2 is arranged in the power shell 1, one end of the power control switch is connected with an external power supply 21, and the other end of the power control switch is electrically connected with the two conductive contact spring pieces 12 so as to control the electrification and the outage of the two conductive contact spring pieces 12;

the detecting switches 3 are arranged in the socket 11 and are distributed around the two jacks 13 at intervals, the detecting switches 3 are connected in series one by one to form a safety detecting loop 30, and finally the two detecting switches 3 on both sides are electrically connected with the power control switch 2, wherein each detecting switch 3 at least has a touch end 31 to protrude into the jack 13 close to the detecting switch for the male plug 4 to contact the full-number detecting switch 3 for conduction so as to start the power control switch 2 and enable the two conductive contact spring pieces 12 to provide normal power.

In a preferred embodiment, as shown in fig. 1, the number of the detecting switches 3 is eight in total, and the detecting switches are divided into two groups, each group having four spaced apart positions disposed at the front and rear of the two sides of each corresponding socket 13. The safety socket 11 is controlled by eight loops of the detection switch 3, which is a 'no power socket' without passing the detection loop verification trigger, and no power is provided.

In a preferred embodiment, the safety detection circuit 30 is formed by connecting the two detection switches 3 separated and arranged in pairs at the front and rear sides of each jack 13 by a vertical jumper, connecting the two detection switches 3 at the front and rear sides near the outer side by a vertical jumper, connecting the two detection switches 3 at the rear side near the inner side of the two jacks 13 by a short jumper, and electrically connecting the two detection switches 3 at the front side near the inner side with the power control switch 2, but the actual wiring manner is not limited thereto.

In a preferred embodiment, as shown in FIG. 3, the socket 11 is a American standard socket having two parallel holes 13 and a ground hole 14. When the double-plug-in sheet 41 of the male gauge plug 4 is not contacted with the detection switch 3 and is in an off state, the detection switch 3 is in an on state along with the fact that the standard double-plug-in sheet 41 is deeply inserted into the edge and is contacted with the contact end 31, and when the double-plug-in sheet 41 with the correct specification is in contraposition insertion, all loops of the detection switch 3 can be normally conducted, the power control switch 2 is started, and the two conductive contact spring sheets 12 are normally conducted to provide power.

In a preferred embodiment, as shown in fig. 4, the socket 11 is a Chinese standard socket having two eight-shaped insertion holes 13 and a grounding hole 14, and the internal wiring can be distributed along the two eight-shaped insertion holes 13. When the double-plug-in strip 41 of the male gauge plug 4 is not contacted with the detection switch 3 and is in a disconnection state, the detection switch 3 is in a conduction state when the standard double-plug-in strip 41 is deeply contacted with the contact end 31 along the edge, and when the double-plug-in strip 41 with the correct specification is in contraposition insertion, all loops of the detection switch 3 can be normally conducted, so that the power control switch 2 is started, and the two conductive contact elastic pieces 12 are normally connected to provide power.
