[0032] Control Principle

[0033] See also Figure 5 As shown, automatic switching is achieved through power failure through two contactors;

[0034] The main power supply is connected to the coil of contactor KM1, the normally open contact of contactor KM1, and the normally closed contact of contactor KM2;

[0035] The standby emergency power supply is connected to the coil of contactor KM2, the normally open contact of contactor KM2, and the normally closed contact of contactor KM1;

[0036] When the main power supply is powered on, the KM1 coil is energized, the normally open contact of KM1 on the main power supply is closed, and the normally closed contact of KM1 on the auxiliary emergency power supply is disconnected. The main power supply is powered, and the standby emergency power supply cannot supply power;

[0037] When the main power supply is cut off, the KM1 coil loses power, the closed contacts of KM1 on the main power supply are opened, and the open contacts of KM1 on the standby emergency power supply are closed. At the same time, the KM2 coil on the standby emergency power supply is energized, the normally open contacts of KM2 on the standby emergency power supply are closed, and the standby emergency power supply automatically supplies power.

[0038] In some embodiments see Figure 2 and 3 As shown in FIG. 4 , the cable management assembly 20 includes a cable clamp seat 203, on which a cable clamp cover 204 is rotatably mounted, and the cable clamp seat 203 and the cable clamp cover 204 are both provided with at least one set of cable clamping openings 205 that can clamp the wires when closed, and the cable clamp seat 203 is detachably mounted on the mounting frame 201. The mounting frame 201 is provided with a positioning hole 201a and a slide groove 201b;

[0039] The clamp seat 203 is provided with a mounting ear 203a, and the clamp seat 203 is embedded in the slide groove 201b through the mounting ear 203a, and the pin 202 is inserted into the positioning hole 201a and is detachably mounted on the mounting frame 201. The clamp seat 203 is provided with a magnet 206, and the clamp cover 204 is provided with an iron buckle 207 adapted to the magnet 206. The clamp cover 204 is also provided with a fastening screw 208 through a thread;

[0040] The wire clamp seat 203 is provided with a screw hole adapted to the fastening screw 208 .

[0041] It should be noted that this makes it easier to arrange the wires in the box in a standardized manner.
