Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and more specifically, to a rainproof junction box. Background Technology

[0002] A junction box is an electrical device used to connect and protect electrical wires. It is widely used in various electrical systems. The main function of a junction box is to provide a safe and reliable environment that allows wires to be safely connected and branched, while protecting them from damage caused by the external environment.

[0003] Because multiple wires converge and connect inside a junction box, these wires generate a significant amount of heat, causing a rapid increase in the box's internal temperature. Therefore, junction boxes often have ventilation holes connected to the interior, allowing airflow for heat dissipation. However, for outdoor wiring, if rainwater enters the junction box through these holes, it cannot drain and accumulates. As the water level rises, contact with the wiring terminals can easily cause short circuits or even paralyze the power supply. Furthermore, water can easily seep into the box through gaps between cables and wiring openings. The box's seal between the box and base plate is also often inadequate, resulting in poor waterproofing. Rainwater can easily corrode the internal structure, causing short circuits or reducing the box's lifespan, and can lead to dangerous accidents such as electrical leakage and electric shock, posing a significant safety hazard.
