[0027] Example
[0028] The present embodiment provides a socket for preventing mis-insertion, comprising a shell 1 and a socket 2 arranged above the shell 1 for inserting a plug, wherein a protective structure for preventing mis-insertion is arranged in the socket 2, and the socket 2 comprises a neutral wire hole 21, a live wire hole 22 and a ground wire hole 23, and the protective structure comprises a protective plate 3 covering the opening direction of the ground wire hole 23 and a driving member 4 for driving the protective plate 3 to rotate, wherein the driving member 4 has an elastic restoring force, and the driving member 4 is rotationally connected to the shell 1, and the protective plate 3 has a protective state covering above the ground wire hole 23 and a yielding state when the plug is inserted and rotated counterclockwise.
[0029] The above specific improvements are: Figure 1 and Figure 2 As shown, compared with the prior art, the socket 2 includes a neutral wire hole 21, a ground wire hole 23 and a live wire hole 22. The ground wire hole 23 is provided with a protective plate 3 and a driving member 4 for driving the protective plate 3 to rotate so as to make way for the plug to be inserted. When an external plug is inserted, the plug will squeeze the protective plate 3, thereby causing the driving member 4 to rotate. When the plug is pulled out, due to the elastic restoring force of the driving member 4, the protective plate 3 will be driven to switch from the making way state back to the protection state. At this time, the protective plate 3 covers the ground wire hole 23, thereby preventing external objects from being inserted into the ground wire hole 23.
[0030] On the basis of the above embodiment: the protective structure includes an auxiliary plate 5 arranged inside the shell 1, the driving member 4 includes a hinged rod 6 arranged on the auxiliary plate 5 or the protective plate 3 and a connecting shaft 61 arranged on the other side and adapted to the hinged rod 6, and an elastic recovery member is provided between the hinged rod 6 and the connecting shaft 61.
[0031] On the basis of the above embodiment: the hinge rod 6 is passed through the auxiliary plate 5 , the connecting shaft 61 is arranged on the protection plate 3 , the elastic return member is a torsion spring 7 , and the torsion spring 7 is sleeved on both ends of the hinge rod 6 .
[0032] The above specific improvements are: Figure 3 As shown, the protection structure includes an auxiliary plate 5, which is arranged above the ground wire hole 23, the live wire hole 22 and the neutral wire hole 21. There is a circular hole on the auxiliary plate 5, and the hinged rod 6 is inserted into the circular hole. There is also a through hole on the connecting shaft 61. During the installation process, it is necessary to first insert the hinged rod 6 into the circular hole, and then pass the through hole on the protection plate 3 through the end of the hinged rod 6 facing away from the circular hole, and then set a torsion spring 7 between the two opposite connecting shafts 61 to make the hinged rod 6 have elastic restoring force.
[0033] On the basis of the above embodiment: a snap-fit device is provided between the protection plate 3 and the auxiliary plate 5 , and the snap-fit device includes a snap-fit block 8 arranged on the auxiliary plate 5 or the protection plate 3 and a snap-fit groove 81 arranged on the other side and adapted to the snap-fit block 8 .
[0034] The above specific improvements are: Figure 2 As shown, when the protective plate 3 switches from the yielding state back to the protecting state, the protective plate 3 will rotate clockwise. When the snap-fit groove 81 on the protective plate 3 is engaged with the snap-fit block 8, the protective plate 3 stops rotating. Therefore, by setting the snap-fit block 8, the rotation angle of the protective plate 3 can be effectively limited.
[0035] On the basis of the above embodiment: the protection structure also includes an anti-insertion component arranged in the neutral wire hole 21 and the live wire hole 22, the anti-insertion component includes a first stopper 9 covering the neutral wire hole 21 and a second stopper 91 covering the live wire hole 22, and the auxiliary plate 5 is provided with a first elastic member 11 for assisting the movement of the first stopper 9 and a second elastic member 12 for assisting the movement of the second stopper 91.
[0036] The above specific improvements are: Figure 2 and Figure 3As shown, the protection structure also includes an anti-plugging component arranged in the neutral wire hole 21 and the live wire hole 22, the first stop block 9 is arranged above the neutral wire hole 21, the second stop block 91 is arranged above the live wire hole 22, and the first elastic member 11 and the second elastic member 12 are respectively arranged on the sides of the first stop block 9 and the second stop block 91. Through the setting of the first elastic member 11, it can be ensured that when the plug is unplugged, the first stop block 9 can be moved back to the top of the neutral wire hole 21 to cover the neutral wire hole 21, and through the setting of the second elastic member 12, it can be ensured that when the plug is unplugged, the second stop block 91 can be moved back to the top of the live wire hole 22 to cover the live wire hole 22.
[0037] Based on the above embodiment: the first elastic member 11 includes a first positioning block 111 fixed above the auxiliary plate 5 and a first spring 112 arranged between the first positioning block 111 and the first stop block 9; the second elastic member 12 includes a second positioning block 121 fixed above the auxiliary plate 5 and a second spring 122 arranged between the second positioning block 121 and the second stop block 91.
[0038] The above specific improvements are: Figure 3 As shown, the first spring 112 is connected to the first stop block 9 and the first positioning block 111, and the second spring 122 is connected to the second stop block 91 and the second positioning block 121. When the plug is inserted into the socket 2, the plug will first contact the guide slopes on the first stop block 9 and the second stop block 91. When the plug continues to be inserted downward, it will continue to push the first stop block 9 to move toward the side close to the first positioning block 111, and push the second stop block 91 to move toward the side close to the second positioning block 121.
[0039] On the basis of the above embodiment: a first positioning bead 13 engaged with the first spring 112 is provided at the position where the first stop block 9 is connected to the first spring 112, and a second positioning bead 14 engaged with the second spring 122 is provided at the position where the second stop block 91 is connected to the second spring 122.

By setting the second positioning bead 14, the end position of the second spring 122 can be effectively fixed to prevent it from popping out during the movement.
[0041] On the basis of the above embodiment: the housing 1 includes a base 101 and a cover plate 102 , a waterproof protective film 31 is arranged between the base 101 and the cover plate 102 , and the waterproof protective film 31 covers the neutral wire hole 21 , the live wire hole 22 and the ground wire hole 23 .
[0042] The above-mentioned specific improvements are as follows: the waterproof protective film 31 is arranged above the neutral wire hole 21, the live wire hole 22 and the ground wire hole 23, and the waterproof protective film 31 has a through groove at a position opposite to the neutral wire hole 21, the live wire hole 22 and the ground wire hole 23. The gap of the through groove is small and it is not easy for water to pass through. In this way, the arrangement of the waterproof protective film 31 can facilitate the plug to be inserted into the socket 2 below the waterproof protective film 31, and can greatly isolate the water, which can effectively play a waterproof role of the socket.
[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
