The terminal fixing part and the wire fixing part are detachably connected together through the connecting part. The terminal fixing part is provided with a terminal mounting position. The wire fixing part is provided with a wire fixing position. When in use, the terminal and the wire are fixed together during terminal welding while the basic position is limited, and the terminal wire is taken out after terminal wire welding is completed. A wire terminal welding jig is disclosed in Chinese patent application No. CN202120184850.7, which is generally described as including a fixed block, a fixed plate and a workpiece. The fixed plate has a pressing assembly and a clamping assembly. When in use, the workpiece is firmly clamped on the jig through the pressing assembly and the clamping assembly.

The existing terminal welding combined jig mostly has no terminal front and back fool-proof function. When operating, the terminal is not easy to detect if it is placed in reverse.
