[0004] However, when the device is in use, the connection is sealed by pushing the insulating sealing device of the busbar connection point. However, repeatedly pushing the insulating sealing device of the busbar connection point is likely to cause the insulating sealing device of the busbar connection point to be worn. After being used for too long, the insulating sealing device of the busbar connection point is likely to cause shaking, thereby reducing the use effect of the insulating sealing device of the busbar connection point. Therefore, a busbar joint that can be disassembled at a fixed point of a distribution cabinet is proposed to solve the above problems. Utility Model Content
