Explosion proof junction box is a kind of connector with strong explosion-proof and sealing property for circuit laying. From the appearance, it is a sealed box. It is used in chemical, pharmaceutical and other measurement applications with explosion-proof requirements. It can also be used in the explosive environment of petroleum, chemical and other enterprises as telephone cable wiring and branching. The explosion-proof weighing system is composed of explosion-proof digital instruments, explosion-proof sensors, etc. Explosion proof junction box is composed of cover, body, connecting terminal, diode, connecting wire and connector. The shell has strong anti-aging and UV resistance, which meets the use requirements under outdoor harsh environmental conditions. The self-locking function makes the connection more convenient and firm. It must have waterproof sealing design, scientific anti electric shock insulation protection, and better safety performance. Features and functions of explosion-proof junction box: 1. Explosion proof junction box is generally composed of junction box cover, box body, connecting terminal, diode, connecting wire and connector. Compared with the ordinary junction box, the anti-aging and corrosion ability of its shell is  lengthen many times. 2. The product is designed to adapt to various harsh environments. 3. The special self-locking function makes the connection of the product faster and stronger. 4. The structure is completely professional design, with waterproof sealing and anti electric shock function, which is very safe and reliable.
