Description

Technical Field

[0001] This utility model relates to the field of control boxes, specifically an emergency lighting centralized control device with fire alarm linkage. Background Technology

[0002] In centralized emergency lighting control devices, the distribution cabinet frame is a crucial structure supporting various electrical components, and its rationality directly affects the stability, safety, and linkage response efficiency of the device. Some existing centralized emergency lighting control devices with fire alarm linkage have suboptimal electrical connection structures within their distribution cabinet frames. The layout of connecting components such as copper strips and busbars is not reasonable, leading to unstable current transmission and potential signal delays or control failures during fire alarm linkage. Furthermore, some connection components are not securely installed, and loosening is likely to occur after prolonged use, affecting the device's lifespan and reliability. In addition, the connection methods between electrical components are complex, making installation and maintenance inconvenient and increasing subsequent operation and maintenance costs.
