The power connector for transmitting power generally includes a socket connector and a plug connector that are mutually connected. The socket connector includes socket terminals, and the plug connector includes plug terminals. The current terminal is composed of two clamping pieces. When the plug-in terminal is inserted, the two clamping pieces clamp the plug-in terminal to realize conduction connection. The plug-in terminal is fixedly installed in the electrical connector through the clamping force between the clamping pieces, thereby ensuring the stability of the connection between the electrical connectors.

[0003] The terminal structure generally includes a connecting terminal for external plug-in and a welding terminal for internal welding conduction. In the existing terminal structure, the connecting terminal and the welding terminal are directly welded and fixed together through welding conduction. When such a connecting structure is used in a vibrating working environment, the welding structure between the connecting terminal and the welding terminal is prone to falling off in long-term vibration, thereby affecting the service life of the overall product and making the use of the terminal structure have great limitations. At the same time, the welding method requires higher installation precision of the connecting terminal and the welding terminal. The positions of the two welding parts should be correctly matched during installation. Therefore, it is necessary to further improve the existing terminal structure. SUMMARY

The two ends of the flexible connecting piece are connected in conduction with the first connecting part and the second connecting part, respectively.

[0007] As a preferred scheme, the first body part is integrally outwardly bent to form a welding part matched with the outside, and the welding part is two parts arranged at intervals along the front and back of the side of the first body part.
