Explosion-proof junction box is a connection device with explosion-proof and strong sealing in circuit laying. From the outside it looks like a closed box. When the cable is passed through, the cable enters, exits and is connected through the lock nut, which effectively avoids the phenomenon of sparks at the connection. And its shell is usually made of aluminum alloy. In order to make it have better fire resistance and corrosion resistance, aluminum alloy is often sprayed on its surface.

The junction box consists of box cover, box body, terminal block, diode, connecting wire and connector. The shell must have strong anti-aging and anti-ultraviolet capabilities, and meet the requirements of harsh outdoor environmental conditions, and the self-locking function makes the connection method more convenient and firm. The connection terminals must be firmly installed and have good solderability with the bus. The connectors and connecting wires have good insulation performance, and the male and female plugs with self-locking function make the solar panel and electrical connection more convenient and reliable.
