This embodiment effectively enhances the overall mechanical strength of the connector, improves its resistance to external impact and vibration, and extends its service life by tightly integrating the alloy base 2 with the housing 1 and the fixing portion 13, particularly by extending the plug sleeve 21 on the alloy base 2 into the plug cavity 111. The insulator 3 is cleverly positioned within the plug sleeve 21, providing reliable electrical isolation for the power terminals 4 and preventing the risk of short circuits, thereby ensuring the safety and reliability of the electrical connection. The trapezoidal shape of the mounting portion 12 and the built-in mounting platform 121 not only facilitate rapid positioning and fastening of the connector to the device, but also facilitate subsequent maintenance and inspection. The larger outer diameter of the mounting portion 12 increases the contact area and improves the stability of the installation. The plug cavity 111 design of the plug portion 11 optimizes the plugging path, making the docking process between the plug and the connector smoother, reducing resistance and wear during insertion and removal, and improving work efficiency and user experience. Through its unique structural design, excellent electrical performance, and convenient installation and maintenance features, this embodiment brings significant technological advancements and application value to the field of electrical connections.

[0025] The plug-in portion 11 is provided with a plug-in surface, a plug-in ring 112 is provided on the periphery of the plug-in surface, and a reinforcing rib 113 is provided between the plug-in ring 112 and the mounting portion 12. In this embodiment, the design of the plug-in surface optimizes the contact area, ensuring the smooth transmission of signals or currents, while reducing contact resistance and improving transmission efficiency. The introduction of the plug-in ring 112 not only serves as a physical limiter to effectively prevent dislocation and loosening during the plug-in process, but also further strengthens the stability of the connection point through its structural strength. The reinforcing ribs 113 cleverly arranged between the plug-in ring 112 and the mounting portion 12 greatly enhance the bending and torsion resistance of the entire connection structure, and can maintain the reliability and durability of the connection even in complex and changeable working conditions.

[0026] The outer periphery of the plug cavity 111 is provided with a plug positioning groove 114, the top of the plug cavity 111 is provided with a plug snap groove 115, and one side of the plug snap groove 115 is provided with a snap retaining groove 116.

At the same time, the connection design between the cavity 25 and the plug sleeve 21 ensures the smoothness of the electrical connection path, reduces the contact resistance, and improves the signal transmission efficiency. The tight fit between the fastening strip 31 provided on the insulator 3 and the plug sleeve 21 effectively prevents the insulator 3 from loosening under vibration or external force, thereby enhancing the stability and durability of the connection. The design of the limit buckle 251 in the cavity 25 accurately limits and fixes the insulator 3, which not only simplifies the assembly process, but also ensures the precise positioning of the insulator 3 in the working state, avoiding the risk of poor contact or short circuit caused by position offset. The plug end 41 facilitates quick docking with external equipment, the fixed end 42 is firmly embedded in the interior of the insulator 3, and the pin end 43 flexibly extends downward, facilitating connection with substrates such as circuit boards. The overall design improves the integration and flexibility of the connector.
