Example 2:

in this embodiment, the spring groove and the spring 5 are provided obliquely, and the other component structures are the same as those of embodiment 1.

The working principle of the invention is as follows:

before the device is used, a spring 5 jacks up a three-wire protective door 3 and a two-wire protective door 4, a three-wire jack plug 3.2 is inserted into a three-wire jack 1.1 of an upper cover of the protective door, and a two-wire jack plug 4.3 is inserted into a two-wire jack 1.2 of the upper cover of the protective door;

when the two-wire plug is used, the plug pushes down the two-wire jack plug 4.3 in the two-wire jack 1.2 of the protective door upper cover, the second support rod 4.1 of the two-wire protective door 4 moves downwards along the clearance track between the first support 1.3 and the second support 2.3, the head of the spring is distorted, when the two-wire jack plug 4.3 completely moves out of the two-wire jack 1.2 of the protective door upper cover, the second support rod 4.1 touches the slope surfaces of the first support 1.3 and the second support 2.3 downwards, the second support rod 4.1 moves downwards along the slope surfaces in a slanting way, the spring 5 is compressed in the spring groove, the two-wire protective door 4 deflects downwards in a slanting way, when the second support rod 4.1 moves to the bottom of the slope surface, the two-wire protective door 4 moves to align the two-wire protective door jack 4.5 with the two-wire jack 1.2 of the protective door upper cover, the plug is inserted into the socket, the plug sequentially passes through the two-wire protective door upper cover jack 1.2, the two-wire jack 4.5 and the protective door jack, when the plug is inserted into the circuit of the socket, the circuit is connected, and in the process of inserting the plug, the plug can not contact any live point due to the action of the two-wire protective door 4, so that the safety in the inserting process is ensured, and the national standard requirement is met.

When the two-wire plug is pulled out, the two-wire protective door 4 is arranged between the circuit board and the plug to prevent electric arcs from splashing during pulling out, after the plug is pulled out, the two-wire protective door 4 moves upwards under the action of the spring 5 and returns to the original position, the two-wire protective door jack 4.5 deviates from the two-wire jack 1.2 of the protective door upper cover, the two-wire jack plug 4.3 is inserted into the two-wire jack 1.2 of the protective door upper cover again, and the socket is ensured to be in a non-porous state at ordinary times;

when the three-wire plug is inserted/pulled out, the action process is the same as that when the two-wire plug is inserted/pulled out, the safety of the three-wire plug in/pulled out process is ensured, and the three-wire jack 1.1 of the upper cover of the protective door is ensured to be in a non-porous state at ordinary times;

in addition, because the middle of the two-wire protective door 4 is supported by the first support 1.3, the second support 2.3 and the second support rod 4.1 to form a seesaw structure, when a child inserts a foreign matter into one of the two-wire jacks 1.2 of the upper cover of the protective door when playing, the foreign matter pushes and presses the plug 4.3 of the two-wire jack in the hole inwards, so that one side of the two-wire protective door 4 is stressed to move downwards, the other side of the two-wire protective door is tilted, the two-wire protective door 4 deflects and cannot move downwards integrally, the two-wire jack 1.2 of the upper cover of the protective door cannot leak out, only when the objects are inserted into the two holes simultaneously, the two-wire jack 1.2 of the upper cover of the protective door can completely leak out, and further, the risk of electric shock of the child;

like the second-line protective door 4, the third-line protective door 3 also has an anti-springing function;

only need in the whole operation process plug can, easy and simple to handle, the jack end cap can be along with spring 5 timely insert the jack, factor of safety is high, prevents that the jack from exposing at ordinary times, the risk that the prevention child maloperation arouses.
