Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to embedded cable connectors for mining applications. Background Technology

[0002] In the complex environment of underground coal mine operations, safety is always a paramount consideration. To effectively enhance operational safety, all electrical equipment and control cables used underground require stringent explosion-proof measures. Typically, cable connectors are used to connect electrical equipment to cables. By effectively isolating the connection points, it is possible to prevent explosions caused by dangerous factors such as electric arcs and high temperatures, which could ignite flammable and explosive gases like coal dust and methane. This maximizes the safety of underground workers and ensures normal mine production. However, current cable connectors are relatively large, occupying considerable space and causing inconvenience in confined spaces. This hinders installation, disassembly, and maintenance work. Furthermore, the large size of these connectors can lead to collisions with surrounding equipment or structures, causing damage and impacting the stability and safety of the entire electrical system.
