Therefore, the problem that the socket cannot be waterproof when the pins are not inserted or pulled out is solved.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.

Claims

the protective door is arranged on the lower side of the first shell; the protective door is provided with a pushing inclined plane; the pushing inclined surface is matched with the lower end surface of the jack wall so as to be abutted against the lower end surface of the jack wall to close the jack when the plug pins are not inserted into the jack;

and the restoring mechanism is used for driving the protective door to reset after the plug pins are pulled out of the jack so as to enable the pushing inclined surface to abut against the lower end surface of the wall of the jack, thereby closing the jack.

2. The safety receptacle of claim 1, wherein the face housing unit further comprises a second housing, the protective door being located between the first housing and the second housing; and a plug connector for plugging the plug pins is arranged below the second shell.

3. The safety receptacle of claim 2 wherein said second housing is provided with an upwardly extending weir, said weir defining a ground through-hole therein.

4. A safety receptacle according to claim 3, wherein the jacks are divided into two-pin jacks and three-pin jacks, the two-pin jacks including live and neutral jacks, the three-pin jacks including live, neutral and ground jacks; the ground wire jack is positioned between the live wire jack and the zero wire jack of the two-pin jack.

5. The safety socket of claim 4 wherein the protective door is divided into a first protective door for protecting two-pin jacks and a second protective door for protecting live and neutral jacks of the three-pin jacks; the middle part of the first protective door is provided with an avoidance hole, and the cofferdam penetrates into the avoidance hole.

6. The safety socket of claim 4 wherein a divider plate is further provided between said second housing and said first housing; the live wire jack and the zero wire jack in the tripod jacks and the live wire jack and the zero wire jack in the two tripod jacks are respectively positioned at two sides of the partition plate; the protective door is positioned between the partition plate and the socket housing.

7. The safety socket of claim 1 wherein a stop is provided below the first housing, the stop being provided on one side of the guard door, the stop having a guide portion on a side thereof facing the guard door, the guide portion having an inclined guide surface; the guide part is used for applying upward acting force to the protective door under the combined action of the reset mechanism when the protective door is reset to the lower end face of the push inclined surface abutting against the wall of the inserting hole, so that the push inclined surface is tightly abutted against the lower end face of the wall of the inserting hole.

8. The safety receptacle of claim 7, wherein an end of the guard door adjacent the guide is configured as a ramp adapted to the guide surface.

9. The safety socket of claim 1 wherein said return mechanism is provided as a spring, said spring being provided on one side of said guard door; one side of the protective door is provided with a first spring installation part.

10. The safety receptacle of claim 9, wherein the first spring mounting portion extends diagonally downward and the spring extends diagonally downward from the first spring mounting portion.

11. The safety receptacle of claim 10, further comprising a second spring mounting portion extending obliquely upward, the spring being secured between the first spring mounting portion and the second spring mounting portion.

12. The safety receptacle of claim 11, wherein a fixing block is provided under the first housing, and the second spring mounting portion is formed at a side of the fixing block facing the protection door.

13. The safety receptacle of claim 12, wherein the fixed block is integrally provided to the first housing.

14. The safety receptacle of claim 1, wherein the return mechanism is provided as a magnetic assembly; the magnetic assembly comprises a first magnet and a second magnet, wherein the first magnet is fixed on the protective door, and the second magnet is fixed relative to the shell.

15.
