For explosive hazard environments. The corrosion and explosion-proof distribution box includes the housing, switches installed on the housing, and the control circuit inside the housing. Existing disadvantages of the corrosion and explosion-proof distribution box include: being independently separate, and unable to be assembled together.

The cabinet features switches and has assembly holes on one side. On the opposite side, there is a protruding assembly column that corresponds in position to the assembly holes. By inserting the assembly column of one explosion-proof and corrosion-resistant distribution box into the assembly hole of another, the boxes can be combined for use.

To overcome the aforementioned deficiencies of the existing fireproof and explosion-proof distribution boxes, a fireproof and explosion-proof lighting distribution box that can be assembled for use is available. The box body of the fireproof and explosion-proof distribution box is equipped with switches, and one side features assembly holes. The other side has protruding assembly columns that correspond to the positions of the assembly holes. By inserting the assembly columns of one fireproof and explosion-proof lighting distribution box into the assembly holes of another, the combination use of the fireproof and explosion-proof distribution boxes can be achieved.
