[0002] The use of terminal connecting wires makes connection more convenient and faster, greatly reducing the size of electronic products and reducing production costs. Crimping is a technology that enables permanent circuit connection between wires and contacts. It uses a mechanical means of applying pressure through a controlled deformation process of the exposed wire core in the crimping shaft of a contact.

[0003] Wire harness terminals are generally fixed by crimping to make the terminals electrically connected to the battery cells inside the wire harness. However, during the crimping process, due to the difference in wire harness radius and terminal size, the user needs to replace the corresponding punching die for processing. The disassembly and assembly process is cumbersome and time-consuming, resulting in a decrease in processing efficiency. For this reason, it is necessary to provide a wire harness terminal fast automatic die changing and pressurizing mechanism, which adopts a quickly replaceable structural design and can quickly replace the punching die compatible with the wire harness or terminal in a short time, thereby improving processing efficiency and quickly putting into production and processing.
