[0003] The main purpose of this utility model is to provide a high-protection explosion-proof junction box. It is equipped with sealing structures such as sealing rings at the interface, which effectively improves the sealing and protection performance of the junction box and prevents dangerous media from entering. The interior is equipped with reliable grounding posts and high-quality wiring terminals, which ensures the stability of the line connection and the reliability of grounding. It is suitable for electrical line connections in various hazardous environments.

[0004] To achieve the above objectives, this utility model provides a high-protection explosion-proof junction box, comprising a housing module and an electrical module, wherein the electrical module is built into the housing module, wherein: The outer casing module includes a housing and a top cover, the top cover covering the housing, and a first sealing ring (to improve sealing and explosion-proof capability) is provided at the junction of the top cover and the housing. The housing is provided with multiple interfaces for threading wires. Each interface is equipped with a clamping nut, a T-shaped plug, a flat washer, and a second sealing ring. The T-shaped plug is installed at the interface through the second sealing ring. A flat washer is provided on the side of the T-shaped plug away from the second sealing ring. The clamping nut is in close contact with the side of the flat washer away from the T-shaped plug (to improve sealing and explosion-proof capability). The electrical module includes a wiring terminal and a grounding post, both of which are installed on the inner wall of the housing.

[0005] As a further preferred technical solution to the above technical solution, the housing is bolted to a bracket (the bracket is used to install the entire junction box in a preset position).

[0006] As a further preferred technical solution to the above technical solution, the contact surface between the housing and the top cover is an explosion-proof threaded joint surface.

[0007] As a further preferred technical solution to the above technical solution, the upper cover is provided with a nameplate.

[0008] As a further preferred technical solution to the above technical solution, the number of interfaces is 3.

[0009] The beneficial effects of this utility model are as follows: This utility model discloses a high-protection explosion-proof junction box. By setting sealing rings at the connection between the shell and the top cover, and at the interface, the sealing structure effectively improves the sealing and protection performance of the junction box, preventing the entry of hazardous media. The internal setting of reliable grounding post and high-quality wiring terminals ensures the stability of the line connection and the reliability of grounding, making it suitable for electrical line connections in various hazardous environments.
