2. In the prior art, the plug module can be quickly disassembled and assembled, but the stability of the plug module after being assembled is poor, and the plug module needs to be assembled and disassembled from two ends, so that the plug module is easy to slide; and the contact conductive strips between the plug module and the power distribution unit are worn in the sliding process, so that the plug of the subsequent plug module is further influenced, an arc is easily generated between the plug module and the power distribution unit, and the stability of the plug module is influenced.
