Description

Technical Field

[0001] The utility model belongs to the technical field of wiring devices, in particular to a safety wiring box. Background Art

[0002] A junction box, also known as a junction box or a distribution box, is a device used to connect and manage signal lines such as wires, cables, and optical fibers.

The main function of a junction box is to protect wires and cables from damage or interference, while providing a safe connection point for easy connection and disconnection of lines.

[0003] For safety reasons, existing rolling shutter doors are generally equipped with multiple sensors. For example, an automatic opening and closing system for rolling shutter doors disclosed in the utility model patent with the authorized patent announcement number CN219887945U is adopted, which includes a rolling shutter door, a driving mechanism and a control device. The rolling shutter door includes a door body and a door frame. The door frame is formed with an inlet and outlet, and the door body is used to open or close the inlet and outlet; the driving mechanism is used to drive the door body to rise and fall to open or close the inlet and outlet; the control device includes a controller, a position sensor and a sensing photoeye, and the position sensor, the sensing photoeye and the driving mechanism are all electrically connected to the controller, and the driving mechanism is controlled by the sensing photoeye and the position sensor.
