[0021] By adopting the above technical solution, the side wall of the heat shrinkable insulating tube 3 is connected to the supporting mechanism through the fixing bolts 9. The core components of the supporting mechanism include a fixing ring 8, a connecting block 10, a fixing block 16 and an adjustment system composed of a fixed slider 14, a spring 15 and an adjusting screw 12. The fixing ring 8 is firmly fixed to the heat shrinkable insulating tube 3 by the fixing bolts 9.

[0022] There are three heat-shrinkable insulating tubes 3 in total, and the heat-shrinkable insulating tubes 3 are evenly distributed in a circle on the top of the cable 2. The top of the heat-shrinkable insulating tube 3 is fixedly connected to a terminal protective sleeve 4, and the outer wall of the terminal protective sleeve 4 is provided with an insulating sheet 5. A cover cap 6 is provided on the top of the terminal protective sleeve 4, and a wiring terminal 7 is fixedly connected to the top of the cover cap 6.

First, the three-core finger sleeve 1 is tightly sleeved on the end of the cable 2, as the basic component of the entire terminal, to ensure the stable connection between the cable 2 and the terminal. Then, the heat-shrinkable insulating tube 3 is fixedly connected to the top of the three-core finger sleeve 1. The three heat-shrinkable insulating tubes 3 are evenly distributed in a circle on the top of the cable 2 to provide all-round insulation protection for the cable 2. When the heat-shrinkable insulating tube 3 is fixed, the heat-shrinkable insulating tube 3 is heated by using a hot air gun to shrink it and tightly wrap it around the top of the three-core finger sleeve 1. When heating, it is necessary to control the heating time and temperature to avoid damage to the insulating tube due to overheating;

[0026] A fixed slider 14 is slidably connected in the fixed slot 17 on the side wall of the fixed block 16. One end of the spring 15 is connected to the fixed slider 14, and the other end is fixedly connected to the inner wall of the fixed slot 17. This design allows the fixed slider 14 to maintain a certain stability under the action of the spring 15, and at the same time to slide in the slot under the action of external force. A screw hole is provided at the other end of the fixed slider 14, and a connecting hole 13 is threadedly connected inside the screw hole. A connecting hole 13 is also provided at the other end of the adjusting screw 12. The connection between the adjusting screw 12 and the fixed slider 14 is achieved through the cooperation of the connecting bolt 11 and the connecting hole 13 to adjust the distance between the battery cells. First, according to actual needs, the fixed slider 14 is pushed to move in the fixed slot 17 by rotating the adjusting screw 12, and the change in the distance between the battery cells is observed. When the desired distance is reached, the adjusting screw 12 is stopped from rotating.

[0027] At the top of the cable terminal, a terminal protection sleeve 4 is fixedly connected to the top of the heat shrinkable insulating tube 3 to provide additional protection for the cable terminal. The insulating sheet 5 on the outer wall of the terminal protection sleeve 4 further enhances its insulation performance. A cover cap 6 is provided on the top of the terminal protection sleeve 4.
