[0013] Beneficial effects

[0014] In the present utility model, a limiting hole is provided on one side of the first pin and the second pin. At the same time, the lengths of the first pin and the second pin are different, so the lengths of the second jack and the first jack are also different. Since the lengths of the pins and the jack are different and the limiting hole is provided, it can effectively prevent circuit failures, short circuits and even dangerous situations such as electric shock caused by misplugging, protect the life and property safety of the user, and thus reduce equipment damage caused by misplugging, and effectively avoid adverse consequences caused by misplugging.

However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0024] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Specific Embodiment 1:

[0026] Referring to Figures 1-4 , an anti-misinsertion structure for the ground two-core output line of a reverse plug, including a socket body 1 and a plug 9. A limiting spring 2 is provided inside the socket body 1. A first limiting bump 3 is provided on one side of the limiting spring 2, and the limiting spring 2 and the first limiting bump 3 are welded. A limiting plate 4 is provided on the top of the first limiting bump 3, and the first limiting bump 3 and the limiting plate 4 are connected by positioning. A paddle 10 is provided on one side of the limiting plate 4, and the paddle 10 and the limiting plate 4 are connected by positioning. A second limiting bump 5 is provided on one side of the limiting spring 2. A first pin 6 is provided on one side of the plug 9, and the first pin 6 and the plug 9 are glued. The side of the plug 9 is processed with a rounded corner. Limiting holes 14 are provided on one side of both the first pin 6 and the second pin 7, and the side of the limiting hole 14 is processed with a rounded corner. A second pin 7 is provided on one side of the plug 9, and the second pin 7 and the plug 9 are glued. The side of the plug 9 is processed with a rounded corner. A power transmission line 8 is provided on the back of the plug 9. An indication mark 13 is provided on one side of the plug 9. A second jack 11 is provided on one side of the socket body 1. A first jack 12 is provided on one side of the socket body 1.

[0027] On one side of the first pin 6 and the second pin 7 used by the user, there are both provided with limiting holes 14. At the same time, the lengths of the first pin 6 and the second pin 7 are different. Therefore, the lengths of the second jack 13 and the first jack 12 are also different. Due to the different lengths of the pins and jacks and the provision of limiting holes, it is possible to effectively prevent dangerous situations such as circuit failures, short circuits, and even electric shocks caused by incorrect insertion, ensuring the life and property safety of the user. Therefore, it also reduces equipment damage caused by incorrect insertion and effectively avoids adverse consequences caused by incorrect insertion. Inside the socket body 1, there are two limiting springs 2, and on one side of the two limiting springs 2, there are respectively provided with a first limiting convex block 3 and a second limiting convex block 5. The tops of the first limiting convex block 3 and the second limiting convex block 5 are provided with a limiting plate 4, and the limiting plate 4 controls the expansion and contraction of the first limiting convex block 3 and the second limiting convex block 5. In this way, when in use, it can more effectively prevent the incorrect insertion direction of the plug, improving the reliability of anti-incorrect insertion. When the plug is inserted in the incorrect direction, the limiting convex block can prevent the plug from being forcibly inserted, thereby avoiding damage to the plug 9 and the socket. On one side of the plug 9, there are two indication marks 13. When in use, through the two added indication marks 13, it can more prominently and clearly prompt the correct insertion direction and position, reducing the possibility of incorrect insertion. Its clear and definite indication can effectively avoid incorrect insertion caused by incorrect direction judgment, thereby reducing problems such as circuit failures and equipment damage that may be caused thereby. Specific Embodiment 2:

[0029] Referring to Figures 1-4 , heat dissipation openings are respectively provided on both sides of the socket body 1. In this way, when in use, the added heat dissipation openings can help dissipate the heat generated by the current passing through the socket during use, reducing the internal temperature, reducing circuit failures and component aging caused by overheating, and extending the service life of the socket.

[0030] In summary:

[0031] 1. On one side of the first pin 6 and the second pin 7, there are both provided with limiting holes 14. At the same time, the lengths of the first pin 6 and the second pin 7 are different. Therefore, the lengths of the second jack 13 and the first jack 12 are also different. Due to the different lengths of the pins and jacks and the provision of limiting holes, it is possible to effectively prevent dangerous situations such as circuit failures, short circuits, and even electric shocks caused by incorrect insertion, ensuring the life and property safety of the user. Therefore, it also reduces equipment damage caused by incorrect insertion and effectively avoids adverse consequences caused by incorrect insertion.

Two limiting springs 2 are provided inside the socket body 1, and a first limiting protrusion 3 and a second limiting protrusion 5 are respectively provided on one side of the two limiting springs 2, so that a limiting plate 4 is provided on the tops of the first limiting protrusion 3 and the second limiting protrusion 5. The limiting plate 4 controls the expansion and contraction of the first limiting protrusion 3 and the second limiting protrusion 5. In this way, when in use, the wrong insertion direction of the plug can be more effectively prevented, and the reliability of anti-misinsertion is improved. When the plug is inserted in the wrong direction, the limiting protrusion can prevent the plug from being forcibly inserted, thereby avoiding damage to the plug 9 and the socket.

[0033] 3. Two indication marks 13 are provided on one side of the plug 9, so that when in use, the correct insertion direction and position can be more prominently and clearly prompted through the two added indication marks 13, reducing the possibility of misinsertion. Its clear and definite indication can effectively avoid misinsertion caused by wrong direction judgment, thereby reducing problems such as circuit faults and equipment damage that may be caused thereby.
