AI Technical Summary
When existing junction boxes are used in underground coal mines, they lack effective sealing measures, which allows dust to enter and affect the heat dissipation and insulation performance of electrical components, posing a potential explosion hazard.
Design a sealing component at the connection between the box body and the lid. Through the cooperation of the sealing component and the dustproof groove, a sealed space is formed to prevent dust from entering.
This design effectively seals the junction box, preventing dust from entering, improving the heat dissipation and insulation performance of electrical components, and reducing the risk of explosion.
