[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0027] As shown in the figure, an embodiment of a socket jack safety door of the present invention is provided, wherein the socket jack safety door is fixed on the lower side of an upper cover 1, and the upper cover 1 is provided with at least one pair of first upper cover jacks 8, second upper cover jacks 9, and third upper cover jacks 22, wherein the socket jack safety door comprises a slide box 4, a first slide 2, a first spring 3, a side slide 19, and a side spring 20, wherein the slide box 4 is fixed on the lower side of the upper cover 1, and a first slide box jack 5, a second slide box jack 6, and a third slide box jack 23 corresponding to the positions of the first upper cover jack 8, the second upper cover jack 9, and the third upper cover jack 22 are provided at the bottom of the slide box 4, the first slide 2, the first spring 3, the side slide 19, and the side spring 20 are placed in the slide box 4, and two inclined planes in the same direction are provided at the front and rear ends of the first slide 2, namely, a first inclined plane 13 and a second inclined plane 14, and a seesaw surface 12 is provided on the lower side surface of the middle part of the first slide 2, and the seesaw surface 12 is a V-shaped arc surface with a low middle and high ends. One end of the first spring 3 presses against the first slide 2, and the other end presses against the slide box 4. The first inclined surface 13 of the first slide 2 corresponds to the first upper cover plug hole 8, and the second inclined surface 14 corresponds to the second upper cover plug hole 9. The first inclined surface 13 is provided with a first stop surface 16 at the rear side, and the second inclined surface 14 is provided with a second stop surface 15 at the rear side. The bottom of the slide box 4 is provided with a first stop block 10 and a second stop block 11. The first stop block 10 corresponds to the first stop surface 16, and the second stop block 11 corresponds to the second stop surface 15. The front end of the first slide 2 is provided with a convex piece 24, and the convex piece 24 is a triangle with a larger back and a smaller front. The rear end of the side slide 19 is provided with a groove 25, and the convex piece 24 is covered in the groove 25. One end of the side spring 20 presses against the side slide 19, and the other end presses against the slide box 4. The front end of the side slide 19 is provided with a third inclined surface 21. When the socket hole safety door is assembled, the first slide 2 is subjected to the force of the first spring 3, the side slide 19 is subjected to the force of the side spring 20, the first inclined surface 13 faces the first upper cover hole 8, the second inclined surface 14 faces the second upper cover hole 9, and the third inclined surface 21 faces the third upper cover hole 22, so that the first slide box hole 5, the second slide box hole 6, and the third slide box hole 23 are sealed and in a closed state, the first stop surface 16 is located above the first stop block 10 side, and the second stop surface 15 is located above the second stop block 11 side.

[0028] The slide box 4 is provided with a locking and fixing hole 7, and the upper cover 1 is provided with a mounting column at a position corresponding to the locking and fixing hole 7. The locking and fixing hole 7 is clamped on the mounting column, and a locking bolt is passed through the locking and fixing hole 7 to fix the slide box 4 to the lower side of the upper cover 1.

[0029] The first upper cover plug hole 8 is parallel to the second upper cover plug hole 9 , and the second upper cover plug hole 9 is perpendicular to the third upper cover plug hole 22 .

[0030] The slide box 4 is a semi-enclosed structure with an upper side opening, and a fully enclosed structure is formed when the slide box 4 is fixed to the lower side of the upper cover 1. The first slide 2, the first spring 3, the side slide 19, and the side spring 20 are encapsulated in the fully enclosed structure, which can effectively prevent other structural parts from affecting the sliding of the first slide and the side slide, resulting in failure of the safety door.

[0031] like Figure 6-7 As shown, in the first normal use case, when the 5-15P plug pin 18 is inserted into the safety door, the two pins of the 5-15P plug pin 18 are respectively inserted from the first upper cover hole 8 and the second upper cover hole 9. At this time, the first inclined surface 13 and the second inclined surface 14 of the first slide 2 are balanced by force, and the slide 2 slides to the left, so that the first slide box hole 5 and the second slide box hole 6 at the bottom of the slide box 4 are opened, and the 5-15P plug pin 18 is inserted into the power connection device through the first slide box hole 5 and the second slide box hole 6.

[0032] like Figure 8-11 As shown, in the second normal use case, when the 5-20P plug pin 26 is inserted into the safety door, the two feet of the 5-20P plug pin 26 are respectively inserted from the first upper cover jack 8 and the third upper cover jack 22. At this time, the first inclined surface 13 of the first slide 2 is subjected to downward pressure, and the third inclined surface 21 on the side slide 19 is also subjected to downward pressure. Since the side slide 19 is subjected to downward pressure, the groove 25 on the side slide 19 presses the protrusion 24 on the first slide 2, so that the first inclined surface 13 cannot move downward although it is subjected to downward pressure. The first slide 2 and the side slide 19 are subjected to overall force balance, so that the slide 2 moves to the left ( Figure 8 , 10 As shown in the figure, the protrusion 24 is a triangle with a larger rear portion and a smaller front portion. After moving to the left, the limit of the side slide 19 is released, and the side slide 19 moves backward. The first slide box socket 5, the second slide box socket 6, and the third slide box socket 23 at the bottom of the slide box 4 are opened, and the 5-20P plug pin 26 is inserted into the power connection device through the first slide box socket 5 and the third slide box socket 23.

[0033] like Figure 12-14As shown, in an abnormal operation, if the test probe 17 is inserted from the first upper cover jack 8 alone, the first inclined surface 13 is subjected to downward pressure. Since the third inclined surface 21 is not subjected to force, the groove 25 on the side slide 19 cannot press the protrusion 24, then the first inclined surface 13 is pressed downward, the second inclined surface 14 is tilted upward, and the first stopper 10 blocks the first stop surface 16, so that the first slide 2 cannot slide to the left, and the first slide box jack 5 at the bottom of the slide box 4 is still in a closed state, and the test probe cannot contact the live parts in the socket, thereby playing a role of safety protection. If the test probe 17 is inserted from the second upper cover jack 9 alone, the first inclined surface 13 is not subjected to force to tilt upward, the second inclined surface 14 is subjected to force to press downward, and the second stopper 11 blocks the second stop surface 15, so that the first slide 2 cannot slide to the left, and the second slide box jack 6 at the bottom of the slide box 4 is still in a closed state, and the test probe cannot contact the live parts in the socket, thereby playing a role of safety protection. If the test probe 17 is inserted only from the third upper cover jack 22, the third inclined surface 21 is subjected to downward pressure. At this time, since the first slide 2 has not moved, the protrusion 24 limits the side slide 19, making it impossible for the side slide 19 to move. The third slide box jack 23 at the bottom of the slide box 4 is still in a closed state, and the test probe cannot contact the live parts in the socket, thereby playing a role of safety protection.
