Compared with the top surface and the bottom surface, arranging the port 2 on the side surface makes it more convenient for the staff to connect the lines, and when a fault occurs in one of the ports 2, it is also convenient for the staff to check and repair it, which reduces the difficulty of maintenance to a certain extent and improves the overall practicality.

[0064] As an embodiment of the present utility model, the weak-current terminal block 23 and the strong-current terminal block 22 are located at the same height, which can effectively enhance the neatness of the appearance of the control terminal and the uniformity of the port 2.

[0065] As an embodiment of the present utility model, there are four high-current terminal blocks 22 and four low-current terminal blocks 23. At present, the demand quantity of the high-current terminal blocks 22 and the low-current terminal blocks 23 is roughly equal. Therefore, setting the same number of the high-current terminal blocks 22 and the low-current terminal blocks 23 can achieve uniform distribution, avoiding a series of problems such as too many high-current terminal blocks 22 resulting in excessive use and too few low-current terminal blocks 23 resulting in insufficient number, or too few high-current terminal blocks 22 resulting in insufficient number and too many low-current terminal blocks 23 resulting in excessive use.

[0066] As an embodiment of the utility model, the housing is a polyhedron, which can be reasonably changed according to the specific installation location. The housing needs to be installed on or in the electrical equipment or directly fixed on the wall. For the convenience of installation, at least one surface of the housing is a plane.

[0067] An indicator light 10 is arranged on the housing, and the indicator light 10 indicates the relevant operating status of the control terminal.
