Detailed description of the invention

Referring to fig. 1, the outlet device includes an electric shock preventing outlet and a plug mated with the electric shock preventing outlet. The plug includes a plug body 91 and pins 92, and the pins 92 are made of conductive sheets capable of conducting electricity and vertically protrude downward from the bottom surface of the plug body 91. The electric shock prevention socket comprises an upper panel 1, a lower panel 2, a spring piece 21 and two switch structures. The upper panel 1 is provided with a groove 12, the groove 12 is recessed inwards from the upper wall surface of the upper panel 1, the cross section is rectangular and is matched with the shape of the plug body 91, and the plug body 91 can be inserted into the groove 12. The bottom wall of the groove 12 is provided with a through insertion hole 11. The lower panel 2 is arranged below the upper panel 1 and detachably connected together through a screw, and the lower panel 2 is provided with a spring piece 21, and the spring piece 21 is arranged right below the insertion hole 11. The pins 92 are inserted into the spring pieces 21 through the insertion holes 11.

Two mounting holes 13 are arranged on the side wall of the groove 12 of the upper panel 1, the two mounting holes 13 are opposite in the positive direction, and a switch structure is arranged in each mounting hole 13. The switch structure comprises a sliding block 33, a spring 32 and a button switch 31, wherein the sliding block 33 is movably arranged in the mounting hole 13 and can move back and forth in the horizontal direction, the outer end of the sliding block 33 can extend out of the mounting hole, the button switch 31 is arranged in the mounting hole 13, the spring 32 is arranged between the button switch 31 and the sliding block 33, the sliding block 33 opens the button switch by moving towards the button switch 31, the button switches of the two switch structures are electrically connected with the spring piece 21 after being connected in series, and the spring piece 21 is electrified only when the button switches are pressed simultaneously. The pressing directions of the two push-button switches are just opposite.

The upper wall surface of the outer end part of the switch structure sliding block 33 is an inclined surface, and in the process that the plug body 91 is inserted into the electric shock prevention socket, the plug body 91 acts on the inclined surface of the sliding block 33 to enable the sliding block 33 to move, and further the button switch 31 is pressed to enable the spring piece 21 to be conducted with a power supply. When the plug is pulled out of the electric shock prevention socket, the spring 32 ejects the sliding block 33, the button switch 31 is released, and the spring piece 21 of the electric shock prevention socket is powered off.

The process of energizing the plug-in anti-shock receptacle will be briefly described with reference to fig. 2 and 3. First, the plug is vertically inserted into the groove 12 from the right above the groove 12 of the anti-electric shock socket, and by setting the distance from the upper wall surface of the upper panel 1 to the spring plate 21 and the length of the pin 92, the pin 92 is inserted into the spring plate 21 (as shown in fig. 2) only after the lower end surface of the plug body 91 is inserted into the groove 12, the plug continues to be inserted downwards, and the plug body 91 pushes the sliders 33 of the two switch structures to move towards the button switch 31 so as to open the button switch 31 (as shown in fig. 3). Only after the lower end face of the plug body 91 is completely inserted into the groove 12, the pins are not exposed outside any more, the two sliders 33 respectively press the two button switches 31 under the action of the plug, and at the moment, the spring piece 21 in the socket is electrified. When the lower end face of the plug body 91 is not completely inserted into the groove 12, the pins 92 are not inserted into the spring pieces 21 and do not contact with the spring pieces 21, and the spring pieces 21 are not electrified, so that the electric shock accident caused by the contact of hands and the pins in the process that a child inserts the plug into the socket is prevented. Because two button switches need to press to two different directions respectively just can the circular telegram, increased the reliability of protection against electric shock. As long as one of the two push switches 31 is not pressed, no electricity is applied to the spring plate 21. If the child inserts the jack with the electrically conductive article, can not take place the electric shock accident. Because two button switches 31 are connected in series, and the pressing directions of the two button switches are just opposite and are vertical to the direction of the jack, the electric shock is possible only when actions are needed in three directions, and the safety of electric shock prevention is improved.
