Abstract

This application relates to low-voltage cable branch boxes, belonging to the field of power distribution equipment technology. It includes a box body and a protective baffle assembly for protecting the main control switch and branch switches. This application achieves automatic switching of protection states by connecting the protective baffle assembly to the door leaf drive mechanism. When the door leaf is closed, the baffle retracts to ensure heat dissipation; when half-open, the baffle unfolds to form an isolation barrier, and the lighting simultaneously illuminates for easy inspection; when fully open, the baffle stands upright to provide maintenance space, and the lighting and maintenance lights illuminate simultaneously for illumination and warning. The protective baffle assembly also functions as a wind deflector; its internal air guide channels and inlet / outlet vents, in conjunction with a cooling fan, form a directional airflow, precisely directing airflow to the heat-generating parts of the switches to ensure efficient heat dissipation. Automatic control of lighting and warning is achieved through a flexible limit block at the door leaf pivot point in conjunction with a microswitch. The lights illuminate immediately upon opening the door, and intelligently switch between lighting and warning modes according to the opening degree, further enhancing operational safety.
