Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a highly airtight power distribution terminal box, which includes a box with hinged doors. The box is divided into an equipment room and a ventilation room, an equipment room and a ventilation room. The ventilation room is isolated, and there are ventilation holes on the side wall of the ventilation room. The ventilation room is equipped with an exhaust fan, an air collection box and a box ventilation box. There are two sets of ventilation boxes for the cabinet and the ventilation box, which are connected to the air inlet and outlet of the exhaust fan respectively. The air pipe is a metal tube. The interior of the equipment room is connected. Under the action of the exhaust fan, the air in the equipment room circulates along the path from the equipment room, the cabinet ventilation box, the gas collection box, the exhaust fan, the gas collection box, and the cabinet ventilation box to the equipment room. The air in the ventilation room completes heat exchange; there is a sealing strip at the connection between the cabinet door and the box body, and an interface seat is provided in the equipment room, and the interface seat is fixedly connected with the box body, and the connection between the interface seat and the box body is sealed. Corresponding and electrically connected wire interfaces are provided on both sides to solve the problem of poor sealing of the distribution box in the prior art

Corresponding and electrically connected wire interfaces are provided on both sides of the box; the box body of the power distribution terminal provided by the present invention has good airtightness and high safety performance.

Description

[0001] The invention relates to the technical field of power distribution, in particular to a power distribution terminal box with strong sealing performance. Background technique [0002] For distribution boxes installed outdoors, especially those installed in low-lying areas, when the rainy season comes, due to the heavy rainfall, the low-lying terrain is prone to water accumulation, which often leads to the distribution box being soaked in water, making the distribution box The electrical components in the electrical box are short-circuited, which is prone to danger and damages the electrical components. [0003] Chinese Patent Publication No. "CN208923619U" discloses a distribution box with a distribution box mounting frame and good heat dissipation effect, including a distribution box mounting frame and a distribution box shell installed on the distribution box mounting frame . The installation frame of the distribution box in the utility model can be adjusted according ...
