An existing wiring terminal for battery connection, as Figure 8 shown, includes a terminal middle connection part 60, a terminal lead-out end 61 provided at one end of the terminal middle connection part 60, and a terminal docking part 63 provided at the other end of the terminal middle connection part 60. A terminal post 62 is provided on the terminal docking part 63. During use, it is found that the terminal post 62 is prone to poor contact during docking, posing a safety hazard. After analysis, it is mainly because the terminal middle connection part 60 has no installation and fixing structure, so the terminal post 62 bears a large force. In addition, when the terminal post 62 is connected to the terminal docking part 63 and the docking part, it is only connected by threads, and the connection method is relatively single. With the frequent vibration during the driving of the automobile, the threaded connection part of the terminal post 62 is extremely prone to loosening or even falling off. Therefore, the existing automobile wiring terminal is improved and optimized. Summary of the Utility Model
