An anti-insertion plate 3 is provided at the interface hole 13 to prevent mis-insertion. When inserting the USB, the anti-insertion plate 3 needs to be pushed to the left or right. When the USB is unplugged, due to the loss of the USB limit, the elastic movable part drives the anti-insertion plate 3 to reset under the action of the elastic restoring force, so that the anti-insertion plate 3 always covers the top of the interface hole 13, thereby preventing mis-insertion.
[0031] On the basis of the above embodiment: the upper end surface of the anti-insertion plate 3 is provided with a stopper 4 which can contact with the USB and switch the anti-insertion plate 3 from the protection state to the avoidance state.
[0032] The above specific improvements are: Figure 2 As shown, a stopper 4 is provided on the upper end surface of the anti-insertion plate 3. When inserting a USB, the side of the USB needs to contact the stopper 4, and then the USB is pushed to move the anti-insertion plate 3 toward the side close to the elastic movable member, and finally the USB is inserted into the interface hole 13. Through the provision of the stopper 4, when inserting the USB, the anti-insertion plate 3 can be conveniently driven to make way for the USB.
[0033] On the basis of the above embodiment: an auxiliary plate 5 is arranged in the shell 1, and a first accommodating groove 51 for accommodating an elastic movable member is opened in the auxiliary plate 5, and the elastic movable member includes a first spring 6, and an extension block 31 is arranged on the side of the anti-insertion plate 3 facing away from the abutment block 4, and the extension block 31 can reciprocate along the length direction of the first accommodating groove 51, and the extension block 31 is arranged on the lower end surface of the anti-insertion plate 3, and a first card bead 32 that abuts against the first spring 6 is arranged on the extension block 31.
[0034] The above specific improvements are: Figure 3 and Figure 4 As shown, an auxiliary plate 5 is provided inside the shell 1, and a first accommodating groove 51 is provided on the auxiliary plate 5, and a first spring 6 is installed in the first accommodating groove 51. The part of the anti-insertion plate 3 inserted into the first accommodating groove 51 has an extension block 31, and a first card bead 32 is provided on the extension block 31. The first card bead 32 is engaged with the first spring 6. When the USB needs to be inserted into the interface hole 13, it needs to contact the stop block 4, and then push the anti-insertion plate 3 to move toward the side. At this time, the first spring 6 is compressed and deformed, and at the same time, the anti-insertion plate 3 will also move along the length direction of the first accommodating groove 51, thereby making way for the USB.
[0035] On the basis of the above embodiment: a second clamping bead 52 is provided on the side of the first receiving groove 51 facing away from the extending block 31 , and the first spring 6 is clamped between the first clamping bead 32 and the second clamping bead 52 .
[0036] The above specific improvements are: Figure 4As shown, in order to fix the position of the first spring 6 , two sides of the first spring 6 are respectively engaged with the first locking bead 32 and the second locking bead 52 .
[0037] On the basis of the above embodiment: the shell 1 is also provided with a socket 7 for inserting a plug, and the socket 7 is provided with a protective structure for preventing wrong insertion, the socket 7 includes a neutral wire hole 71, a live wire hole 72 and a ground wire hole 73, the protective structure includes a protective plate 8 covering the opening direction of the ground wire hole 73 and a driving member 9 for driving the protective plate 8 to rotate, the driving member 9 is rotationally connected to the shell 1, and the protective plate 8 has a protective state covering above the ground wire hole 73 and a yielding state when the plug is inserted and rotates counterclockwise.
[0038] The above-mentioned specific improvements are as follows: the jack 7 includes a neutral wire hole 71, a ground wire hole 73 and a live wire hole 72. The ground wire hole 73 is provided with a protective plate 8 and a driving member 9 for driving the protective plate 8 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 8, thereby causing the driving member 9 to rotate. When the plug is pulled out, due to the elastic restoring force of the driving member 9, the protective plate 8 will be driven to switch from the making way state back to the protective state. At this time, the protective plate 8 covers the ground wire hole 73, thereby preventing external objects from being inserted into the ground wire hole 73.
[0039] Based on the above embodiment: the driving member 9 includes a hinged rod 91 arranged on the auxiliary plate 5 or the protective plate 8 and a connecting shaft 92 arranged on the other side and adapted to the hinged rod 91, and an elastic return member is provided between the hinged rod 91 and the connecting shaft 92.

[0041] The above-mentioned specific improvements are as follows: the hinge rod 91 is passed through the auxiliary plate 5 , the connecting shaft 92 is arranged on the protection plate 8 , the elastic return member is a torsion spring 2 , and the torsion spring 2 is sleeved on both ends of the hinge rod 91 .
[0042] On the basis of the above embodiment: the shell 1 includes a base 11 and a cover plate 12, a waterproof protective film 21 is arranged between the base 11 and the cover plate 12, and the waterproof protective film 21 covers the neutral wire hole 71, the live wire hole 72, the ground wire hole 73 and the interface hole 13.
[0043] The above-mentioned specific improvements are as follows: the waterproof protective film 21 is arranged above the neutral wire hole 71, the live wire hole 72 and the ground wire hole 73, and the waterproof protective film 21 has a groove at a position opposite to the neutral wire hole 71, the live wire hole 72 and the ground wire hole 73. The gap of the groove is small and it is not easy for water to pass through. In this way, the arrangement of the waterproof protective film 21 can facilitate the plug to be inserted into the socket 7 below the waterproof protective film 21, and can greatly isolate the water, which can effectively play a waterproof role of the socket.
[0044] 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.
