Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, specifically to an electrical connector that prevents mis-mating. Background Technology
[0002] Electrical connectors, also known as connectors or plugs, are electromechanical components used to connect two or more electronic circuits. They act as bridges in electronic devices, enabling electrical connections and signal transmission within and between devices. Because the structures of electrical connectors used are quite similar, it is difficult for workers to quickly and accurately distinguish between connectors that look alike. This can lead to plugs being inserted into incompatible sockets, which can not only affect the normal operation of the equipment but may even damage the electrical connectors and related equipment due to the mismatched connection.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202323106593.3, application date 2023-11-17) provides an electrical connector with anti-misinsertion function, including a base plate, a plug on the top of the base plate, a plurality of pins on the top of the plug, a plug plate fixedly mounted on the top of the plug with the plug plate on the side of the pins, a plug socket connected to the top of the plug, the plurality of pins and the plug plate being inserted into the interior of the plug socket, an anti-slip structure on the outer side of the plug socket, and a connecting structure on both sides of the plug. In use, the plug plate is aligned with the limiting hole at the bottom of the plug socket to connect the plug socket and the plug together, thereby preventing misinsertion. At the same time, the buckles on both sides of the plug are fastened into the limiting plate on the top of the plug socket, and the buckles limit and fix the plug socket to prevent the plug socket from easily detaching from the plug.
[0004] When electrical connectors are used in harsh environments, external dust particles can enter the connector, which not only accelerates the wear of the contact surfaces and increases contact resistance, but also affects the stability of the electrical connection. The aforementioned devices cannot protect the electrical connector during use, allowing harmful substances such as moisture and dust in the environment to penetrate the connector, affecting its normal operation, accelerating corrosion, and shortening its service life. Utility Model Content
[0005] The purpose of this utility model is to provide an electrical connector that prevents mis-mating, so as to solve the problem mentioned in the background art that the electrical connector cannot be protected, allowing harmful substances such as moisture and dust in the environment to enter the interior of the electrical connector, affecting the normal operation of the electrical connector, accelerating the corrosion of the electrical connector, and shortening the service life of the electrical connector.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-misinsertion electrical connector, comprising an electrical connector and a plug assembly, wherein a connecting post is movably connected to the front side of the electrical connector, and a connecting block is fixedly connected to the outside of the connecting post, and a positioning groove is formed inside the connecting block, while a connecting groove is formed inside the electrical connector; a fixing post is fixedly connected to the surface of the plug assembly, and a positioning post is fixedly connected to the outside of the fixing post, and the positioning posts are symmetrically distributed about the center of the outside of the fixing post, and the positioning posts correspond one-to-one with the positioning grooves; a baffle is fixedly connected to the lower outer end of the electrical connector, and a pull rod is slidably connected inside the baffle.

Users can quickly replace connecting posts of different specifications, shapes, or materials according to actual needs, enabling the electrical connector to flexibly adapt to various complex and ever-changing application scenarios.
[0016] Furthermore, it facilitates maintenance of the connecting posts by staff, which not only improves the overall performance of the electrical connector but also extends its service life.

[0020] 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.
[0021] Example 1: The positioning groove 7, connecting groove 16, and positioning post 5 enable the plug assembly 3 and electrical connector 1 to quickly and accurately complete the connection operation, improving the working efficiency of the device. Figures 1-2 As shown: It includes an electrical connector 1 and a plug assembly 3. The front side of the electrical connector 1 is movably connected to a connecting post 2, and a connecting block 6 is fixedly connected to the outside of the connecting post 2. The connecting block 6 has a positioning groove 7 inside, and the electrical connector 1 has a connecting groove 16 inside. The surface of the plug assembly 3 is fixedly connected to a fixing post 4, and a positioning post 5 is fixedly connected to the outside of the fixing post 4. The positioning posts 5 are symmetrically distributed about the center of the outside of the fixing post 4, and the positioning posts 5 correspond one-to-one with the positioning grooves 7. A baffle 17 is fixedly connected to the lower outer side of the electrical connector 1, and a pull rod 18 is slidably connected inside the baffle 17.
[0022] The operator holds the plug assembly 3 and brings it close to the connecting post 2 on the surface of the electrical connector 1. The operator aligns the plug assembly 3 with the positioning groove 7 using the connecting block 6 on the surface of the plug assembly 3 to ensure that the plug assembly 3 and the electrical connector 1 are connected in the correct direction and position. When the telescopic block 15 on the surface of the moving block 12 at the lower end of the connecting post 2 contacts the outside of the electrical connector 1, the connection between the plug assembly 3 and the electrical connector 1 is completed. The positioning groove 7 and the positioning post 5 enable the connection operation to be completed quickly and accurately, saving time and improving work efficiency. This greatly improves the success rate and accuracy of the electrical connector 1 connection, while reducing the possibility of mis-insertion.
[0023] In Example 2, unlike Example 1, the installation of the fixing block 8, the isolation plate 10, and the buffer spring 11 improves the protection of the electrical connector 1 and extends its service life. Figures 3-4 As shown: A fixing block 8 is fixedly connected to the inner wall of the connecting column 2, and a rotating shaft 9 is rotatably arranged inside the fixing block 8. An isolation plate 10 is fixedly connected to the surface of the rotating shaft 9. The rotating shaft 9 is rotatably arranged inside the connecting column 2. One end of a buffer spring 11 is fixedly connected to the surface of the isolation plate 10, and the other end of the buffer spring 11 is fixedly connected to the connecting column 2. The isolation plate 10 is rotatably arranged inside the connecting column 2. A moving block 12 is fixedly connected to the lower surface of the connecting column 2, and a sliding groove 13 is opened inside the moving block 12. The moving block 12 is slidably arranged on the surface of the connecting groove 16.
[0024] When the electrical connector 1 and the plug assembly 3 are connected, the plug assembly 3 is pushed to slide inside the connecting post 2, and the plug assembly 3 contacts the isolation plate 10 on the inner wall of the connecting post 2. This causes the plug assembly 3 to push the isolation plate 10 to rotate inside the connecting post 2, causing the buffer spring 11 on the surface of the isolation plate 10 to retract towards the inner wall of the connecting post 2, thereby achieving the connection between the electrical connector 1 and the plug assembly 3. The isolation plate 10 and the connecting post 2 improve the protection of the electrical connector 1 and help maintain the overall sealing of the electrical connector 1. At the same time, the isolation plate 10 can effectively block corrosive substances from eroding the interior of the electrical connector 1, ensuring that the electrical connector 1 can work stably. Furthermore, the isolation plate 10 is made of a material with high insulation performance, which not only reduces the risk of leakage of the electrical connector 1, but also improves the working reliability of the electrical connector 1 in high voltage environments.
[0025] In Example 3, unlike Example 2, the connecting rod 18, baffle 17, and spring 19 allow workers to disassemble the connecting column 2, facilitating its maintenance. Figures 5-7 As shown: one end of a first spring 14 is fixedly connected to the surface of the sliding groove 13, and the other end of the first spring 14 is fixedly connected to a telescopic block 15. The telescopic blocks 15 are symmetrically distributed about the center of the moving block 12. One end of a second spring 19 is fixedly connected to the surface of the pull rod 18 near the connecting groove 16, and the other end of the second spring 19 is fixedly connected to a baffle 17. The pull rod 18 is symmetrically distributed about the center of the electrical connector 1. The surface of the pull rod 18 is in contact with the surface of the telescopic block 15. The plug assembly 3 is slidably disposed inside the connecting post 2.
[0026] When the operator disassembles the connecting post 2, the pull rod 18 is pressed, causing the pull rod 18 to slide inside the baffle 17. This causes the second spring 19 on the surface of the baffle 17 to extend towards the pull rod 18. As the pull rod 18 slides, it compresses the telescopic block 15 on the surface of the moving block 12, causing the telescopic block 15 to slide inside the sliding groove 13. At the same time, the first spring 14 retracts towards the inner wall of the moving block 12. When the telescopic block 15 is fully inside the moving block 12, the connecting post 2 can be separated from the electrical connector 1. Users can quickly replace the connecting post 2 with different specifications, shapes, or materials according to actual needs, enabling the electrical connector 1 to flexibly adapt to various complex and ever-changing application scenarios.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
