[0002] Lithium batteries need to be fully tested and verified by battery testing equipment before they can be put on the market. The battery testing equipment and the battery need to be electrically connected using a channel cable, and a transfer terminal for connecting the cable is provided at the output end of the testing equipment. The common transfer terminals on the market currently have a cylindrical head structure for the external connection and a single threaded hole, without a left or right limit structure. The process of locking the copper nose is relatively laborious. To ensure the direction of the copper nose after locking, a large force is required to control the cable to ensure that it does not rotate. After locking the copper nose, it is often protected by adding a protective cover. Since the external connection part is a cylindrical structure, it is difficult to maintain a uniform direction after the protective cover is put on, and the adjustment process is more troublesome.
