[0030] Working principle: low-voltage distribution cabinet is a general term for motor control center. Distribution box is to assemble switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements to form a low-voltage distribution device. The housing of the distribution cabinet plays a certain protective role on the internal structure. When using the connection device 5, place the connection plate 1 at the bottom, and then put the connection groove 501 opened at the bottom of the side plate 2 and the back plate 3 on the surface of the connection strip 502 fixed on the top of the connection plate 1, and then fix the bottom of the other connection plate 1. The connecting strip 502 is inserted into the connecting groove 501 opened on the top of the side plate 2 and the back plate 3, and the rectangular block 505 is manually slid into the inside of the connecting port 506, and then the two ends of the U-shaped plate 504 are respectively inserted into the inside of the rectangular groove 503 opened on one side of the two connecting plates 1, and then the bolt 509 is manually rotated so that the bolt 509 is inserted into the inside of the threaded groove 510, and then the U-shaped plate 504 is well connected to one side of the back plate 3, and then the housing of the power distribution cabinet is well assembled.
