AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

This utility model discloses a dustproof mechanism for a mine explosion-proof low-voltage cable junction box, relating to the field of junction box technology. It includes a box body and a cover, with connecting pipes installed at both ends of the box body. A sealing component is provided at the connection between the box body and the cover, and dustproof components are provided at both ends of the box body. In this utility model, the cooperation of the dustproof groove and the positioning groove facilitates the quick positioning and connection of the cover to the box body while forming a sealed space, thereby achieving the purpose of dust prevention. The cooperation of the connecting pipe and the adjusting pipe facilitates the adjustment of the opening size of the sealing pipe, thus adapting to wires of different sizes and improving the sealing effect of the connection. The cooperation of the sealing pipe and the rubber ring facilitates the contact with the wire to prevent dust from entering, improving the sealing effect after the wire enters.
