Description

Technical Field

[0001] This utility model relates to the field of cable junction box technology, and in particular to a portable junction box for explosion-proof cables used in mining. Background Technology

[0002] Coal mines contain explosive gas mixtures such as methane and coal dust. Ordinary cable junction boxes are highly susceptible to explosions if internal electrical sparks or high temperatures are generated, causing serious casualties and property damage. Coal mines also house numerous electrical devices, such as coal mining machines, tunneling machines, ventilation fans, and lighting equipment, all of which require cables for power supply and signal transmission. During equipment installation, maintenance, and line modifications, cable connections and branching are frequently necessary.

[0003] Existing mining junction boxes are complex in structure, large in size, and heavy in weight, making them inconvenient to carry and install. Furthermore, their explosion-proof and insulation performance needs improvement. For example, some junction boxes use heavy cast iron shells, which, while providing some explosion-proof capability, are very difficult to transport and operate, hindering their movement in confined underground spaces and between different work faces. The installation process of traditional junction boxes is cumbersome, requiring specialized tools and considerable time, thus affecting construction efficiency. Therefore, improvements are needed to address these issues. Utility Model Content
