[0002] With the widespread use of Type-C interfaces in various electronic products, their convenience and versatility have been widely recognized. In electronic products such as LED light strips and LED lamps, the correct connection between the input and output terminals is crucial. Incorrect connections may not only cause the device to malfunction but may also lead to safety hazards. However, due to the uniformity of shape and size of existing standard Type-C interfaces, users are very likely to confuse the input and output terminals during blind operation, resulting in reverse connection. Commercially available common Type-C connectors are all standard parts and lack effective reverse connection protection designs. Users cannot easily ensure the correct connection direction by visual judgment during use. Therefore, a data cable that prevents reverse connection of input and output terminals has been designed. Summary of the Invention
[0003] The purpose of this utility model is to provide a data cable that prevents the input and output terminals from being reversed, in order to solve the problem mentioned in the background art that the data cables on the market lack anti-reverse connection design, and users are very likely to confuse the input and output terminals during blind operation, causing reverse connection, which in turn leads to the device not working properly, and may even cause safety hazards.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a data cable that prevents reverse connection of input and output terminals: It includes a socket, one side of which has a Type-C input port, and the other side of which has a Type-C output port. A Type-C input connector is plugged into the Type-C input port, and a Type-C output connector is plugged into the Type-C output port.

A second contact surface is provided on the side of the second socket near the Type-C output port. A second reverse connection plug is fixedly connected to the surface of the Type-C output connector. A second groove is formed on the surface of the second reverse connection plug. A second positioning surface is provided on the side of the second reverse connection plug near the Type-C output connector.

[0012] This data cable features a design where, when the Type-C input connector is plugged into the Type-C output port, the first reverse-connection protection plug cannot be inserted into the second connector, thus preventing the Type-C input connector from being inserted into the Type-C output port. Similarly, when the Type-C output connector is plugged into the Type-C input port, the second reverse-connection protection plug cannot be inserted into the first connector, thus preventing the Type-C output connector from being inserted into the Type-C input port. Furthermore, the shapes of the first and second reverse-connection protection plugs allow users to visually determine the correct insertion positions of the Type-C input and output connectors on the socket, preventing them from being inserted incorrectly into the Type-C input and output ports. This ensures the normal operation of the device and avoids potential safety hazards. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 One embodiment provided by this utility model:
[0021] A data cable for preventing reverse connection of input and output terminals includes a socket 1. One side of the socket 1 has a Type-C input port 11, and the other side has a Type-C output port 3. A Type-C input connector 22 is plugged into the Type-C input port 11, and a Type-C output connector 42 is plugged into the Type-C output port 3. A first socket 12 is located on the side of the socket 1 near the Type-C input port 11. A first protrusion 13 is fixedly connected to the first socket 12. A first contact surface 14 is provided on the side of the first socket 12 near the Type-C input port 11. A first anti-reverse connection plug 2 is fixedly connected to the surface of the Type-C input connector 22. A first groove 21 is formed on the surface of the first anti-reverse connection plug 2. A first positioning surface 23 is provided on the side of the first anti-reverse connection plug 2 near the Type-C input connector 22. A second socket 31 is provided on the side of the base 1 near the Type-C output port 3. A second protrusion 32 is fixedly connected to the second socket 31. A second contact surface 33 is provided on the side of the second socket 31 near the Type-C output port 3. A second anti-reverse connection plug 4 is fixedly connected to the surface of the Type-C output connector 42. A second groove 41 is provided on the surface of the second anti-reverse connection plug 4. A second positioning surface 43 is provided on the side of the second anti-reverse connection plug 4 near the Type-C output connector 42. A data cable body 5 is fixedly connected to one end of both the first anti-reverse connection plug 2 and the second anti-reverse connection plug 4. The data cable body 5 has the function of preventing reverse insertion, which can prevent the Type-C output connector 42 and the Type-C input connector 22 from being inserted into the Type-C input port 11 and the Type-C output port 3 in reverse, thereby ensuring the normal operation of the equipment and avoiding safety hazards.
[0022] Furthermore, the first socket 12 is oval in shape, and the surface area of the first socket 12 is larger than the surface area of the type-c input port 11. The first positioning surface 23 is oval and is inserted into the first socket 12, so that the type-c input connector 22 can pass through the first socket 12 and be inserted into the type-c input port 11.
[0023] Furthermore, the first protrusion 13 is an isosceles trapezoid and is provided in two sets, and the first groove 21 is an isosceles trapezoid and is provided in two sets. The first protrusion 13 is inserted into the first groove 21. When the first anti-reverse connection plug 2 is inserted into the first socket 12, the first protrusion 13 will be inserted into the first groove 21 at the same time, thereby positioning one end of the first anti-reverse connection plug 2 on the first socket 12. Since the first anti-reverse connection plug 2 is oval, the first anti-reverse connection plug 2 cannot be inserted into the second contact surface 33, thereby preventing the type-c input connector 22 from being inserted into the type-c output port 3.
[0024] Furthermore, both the first positioning surface 23 and the first contact surface 14 are oval in shape, and the first positioning surface 23 and the first contact surface 14 are in contact with each other. When the first positioning surface 23 and the first contact surface 14 are in contact, the type-c input connector 22 is firmly inserted into the type-c input port 11, thereby completing the precise insertion of the type-c input connector 22 into the type-c input port 11.
[0025] Furthermore, the second socket 31 is square in shape, and the surface area of the second socket 31 is larger than the surface area of the type-c output port 3. The second reverse connection plug 4 is square in shape and is inserted into the second socket 31, so that the type-c output connector 42 can penetrate the second contact surface 33 and be inserted into the type-c output port 3.
[0026] Furthermore, the second protrusion 32 is an isosceles trapezoid and is provided in two sets, and the second groove 41 is an isosceles trapezoid and is provided in two sets. The second protrusion 32 is inserted into the second groove 41. When the second anti-reverse connection plug 4 is inserted into the second socket 31, the second protrusion 32 will be inserted into the second groove 41 simultaneously, thereby positioning one end of the second anti-reverse connection plug 4 on the second contact surface 33. Since the second anti-reverse connection plug 4 is square in shape, the second anti-reverse connection plug 4 cannot be inserted into the first socket 12, thereby preventing the type-c output connector 42 from being inserted into the type-c input port 11.
[0027] Furthermore, both the second contact surface 33 and the second positioning surface 43 are square, and the second contact surface 33 and the second positioning surface 43 are in contact with each other. When the second contact surface 33 and the second positioning surface 43 are in contact with each other, the type-c output connector 42 is firmly inserted into the type-c output port 3, thereby completing the precise insertion of the type-c output connector 42 into the type-c output port 3.
[0028] Working principle: When the Type-C input connector 22 and Type-C output connector 42 at one end of the data cable body 5 are connected to the Type-C input port 11 and Type-C output port 3, a first anti-reverse connection plug 2 is provided on the Type-C input connector 22 to prevent the Type-C input connector 22 and Type-C output connector 42 from being inserted in reverse. When the first anti-reverse connection plug 2 is connected to the Type-C input port 11, the Type-C input connector 22 will be inserted into the first socket 12, and the first protrusion 13 will be simultaneously inserted into the first groove 21. When the first positioning surface 23 and the first contact surface 14 come into contact with each other, the connection between the Type-C input connector 22 and the Type-C input port 11 is completed. When the Type-C input connector 22 is connected to the Type-C output port 3, the first anti-reverse connection plug 2 cannot be inserted into the second socket 31, thus preventing the Type-C input connector 22 from being inserted into the Type-C output port 3. Similarly, a second anti-reverse connection plug 2 is provided on the surface of the Type-C output connector 42. When the reverse-connection plug 4 is connected to the Type-C output port 3, and the Type-C output connector 42 is connected to the Type-C output port 3, the second reverse-connection plug 4 will be inserted into the second socket 31, and the second protrusion 32 will be inserted into the second groove 41 simultaneously. When the second contact surface 33 and the second positioning surface 43 contact and connect with each other, the connection between the Type-C output connector 42 and the Type-C output port 3 is completed. When the Type-C output connector 42 is connected to the Type-C input port 11, the second reverse-connection plug 4 cannot be inserted into the first socket 12, thus preventing the Type-C output connector 42 from being inserted into the Type-C input port 11. Furthermore, the user can intuitively judge the connection position of the Type-C input connector 22 and the Type-C output connector 42 on the socket 1 by the shape of the second reverse-connection plug 4 and the first reverse-connection plug 2, avoiding the Type-C output connector 42 and the Type-C input connector 22 being inserted backwards into the Type-C input port 11 and the Type-C output port 3, thereby ensuring the normal operation of the equipment and avoiding safety hazards.
