[0026] As shown in Figures 1-3 The present application provides an anti-creeping connector terminal, which comprises a protective piece 1, two connecting pieces 2 are symmetrically clamped on the protective piece 1, the connecting piece 2 comprises a wiring part 21, a plug-in part 22 and a transition part 23 for connecting the wiring part 21 and the plug-in part 22, the wiring part 21 is used for connecting with an external wire, and the plug-in part 22 is used for plugging with a plug pin. In use, the wiring part 21 of the connecting piece 2 is first connected with the external wire, and then clamped on the protective piece 1, which is convenient and fast. The connecting piece 2 is protected by the protective piece 1. Compared with the prior art, the copper feet originally exposed are protected, the risk of electric leakage is reduced, the possibility of electric shock accidents is reduced, and the safety of use is improved. The connecting piece 2 is made of conductive material, the protective piece 1 is made of insulating material, and the entire connecting piece 2 is located in the protective piece 1 when the connecting piece 2 is clamped on the protective piece 1.

[0027] As shown in Figure 1 and Figure 3As shown, the protection piece 1 includes a connecting block 11 and two clamping barrels 12 respectively fixed on the opposite sides of the connecting block 11, the connecting piece 2 is clamped in the clamping barrel 12, the connecting block 11 connects and fixes the two clamping barrels 12, so that the whole protection piece 1 forms a stable overall structure, which enhances the stability and reliability of the protection piece 1 during use. The design of the clamping barrel 12 allows the connecting piece 2 to be directly clamped therein, enabling quick installation of the connecting piece 2 and the protection piece 1, and improving the production and assembly efficiency.

[0028] As shown in Figure 2 and Figure 3 , the plug-in part 22 is a clamping jaw structure, which can tightly hold the plug pin. Compared with the ordinary straight insertion or simple sleeve structure, the clamping jaw structure can apply force to the pin from multiple directions, so that it is not easy to loosen or fall off after insertion, thereby ensuring that the connection between the connector terminal and the plug pin is more stable, and effectively avoiding the problem of poor contact caused by vibration, external force pulling and the like. In addition, the clamping jaw structure has a certain elasticity and flexibility, and can adaptively adjust according to the size of the plug pin. Even if the size of the pin has a certain tolerance, the clamping jaw structure can also realize tight fit through its deformation, ensure good electrical connection, and improve the compatibility of the connector for different specifications of pins.

[0029] As shown in Figure 2 and Figure 3 , the wiring part 21 is a sheet type pressure connection structure. The sheet type pressure connection structure can tightly wrap the metal sheet of the connecting part around the wire by applying pressure, forming a tight physical connection, effectively preventing the wire from loosening or falling off due to external force pulling, vibration and other factors during use, and ensuring the stability and reliability of the connection. The sheet type pressure connection structure is usually operated by using a simple manual pressure connection tool or a small pressure connection device during installation, without the need for professional welding equipment or complex technology, thereby reducing the installation threshold and improving the work efficiency.

[0030] As shown in Figure 2 and Figure 3As shown, the plug-in part 22 is provided with a plurality of clamping barbs 3, which are uniformly fixed on the outer side of the plug-in part 22 and are arranged away from the plug-in end of the plug-in part 22. The design of the clamping barbs 3 can tightly hook the plug pin or the socket structure matched therewith after the plug pin is inserted, thereby generating strong reverse resistance, effectively preventing accidental separation between the plug-in part 22 and the plug pin, and greatly enhancing the firmness of the connection. In complex use environments such as vibration and shaking, the connection between the connector terminal and the plug pin can remain stable. The plurality of uniformly arranged clamping barbs 3 can lock the plug pin from different angles and positions, forming an effect similar to multi-point fixation. Compared with a single clamping barb or unevenly distributed clamping barbs, the clamping barbs can provide more balanced and comprehensive gripping force, making the connection more reliable and avoiding shaking or displacement of the plug pin in the plug-in part 22.

[0031] As shown in Figure 2 , the clamping barrel 12 is provided with a clamping groove 4 matched with the clamping barb 3. The matching relationship between the clamping barb 3 and the clamping groove 4 can provide accurate positioning for the installation of the connecting piece 2 in the clamping barrel 12. During installation, the clamping barb 3 can accurately fall into the clamping groove 4, so that the connecting piece 2 can be installed in the clamping barrel 12 at the correct angle and position, ensuring the assembly accuracy of the entire connector terminal structure and avoiding connection failure or other problems caused by installation deviation. After the clamping barb 3 is embedded in the clamping groove 4, the radial and axial movement of the plug-in part 22 in the clamping barrel 12 can be limited, preventing shaking, rotation or loosening during use, thereby ensuring the reliability and stability of the connector terminal in the working state and reducing electrical faults caused by loose connection.

[0032] As shown in Figure 2 , the clamping barrel 12 is provided with an observation hole 5 communicating with the inside of the clamping barrel 12. During installation, the operator can directly check the cooperation between the connecting piece 2 and the clamping barb 3 and the clamping groove 4 in the clamping barrel 12 through the observation hole 5, ensuring that the clamping is in place, such as clearly seeing whether the clamping barb 3 accurately falls into the clamping groove 4, avoiding the situation that the clamping is not in place or clamping is wrong, and ensuring the accuracy and reliability of the installation. If it is found during installation that the connecting piece 2 is tilted, clamping is not smooth, etc., the observation hole 5 can be used to quickly locate the problem and adjust in time, without the need to disassemble the entire device for rechecking, thereby improving the installation efficiency and reducing the installation time and cost.

[0033] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
