The busbar terminal is connected to the horizontal plate of the connecting plate at a set position. Two long holes are spaced apart on the left and right on the busbar terminal. The busbar terminal is fixedly connected to any two bolt holes on the connecting plate by bolts passing through the long holes; the cable terminal is fixedly connected to the busbar terminal, and the space utilization efficiency is improved by changing the connection direction of the cable and the high-voltage busbar.
