[0002] The existing low-carbon economical small-capacity bus duct adopts the insulation structure of the slot. Compared with the traditional air-type and dense bus duct, it has low material cost and labor cost, and has a high waterproof and dustproof protection level. Impedance, low magnetism, and high cost performance, but because the design of the busbar is a new structure, the traditional busway plug-in box plug assembly cannot be used with it. The design requirements for the distance and the protection level of the plug interface are extremely high, so it is necessary to provide a high-performance, high-waterproof and dustproof plug-in box plug assembly with a new design structure that matches the insulated busway of the compartment.
