The relay control assembly 2 is used to control the circuit to be disconnected when a circuit fault occurs. The drying plug-in board 7 can be stably plugged into the plug-in slot 9 to achieve drying of the internal environment of the control box 1.

[0020] Example 2: On the basis of Example 1, a spring plate slot 11 is provided on the front left side of the control box 1, and a plurality of spring plate springs 12 are fixedly connected to the left end surface of the inner side of the spring plate slot 11. The end of the spring plate spring 12 is fixedly connected to the limit spring plate 6. The right side line of the front end surface of the limit spring plate 6 is rounded. The limit spring plate 6 is limited and connected to the front end of the card slot 13. The plug-in slot 9 is tilted downward from left to right and opened in the plug-in frame 8. The plug-in frame 8 is vertically provided with a plurality of ventilation slots 10. When installing the drying plug-in plate 7, the drying plug-in plate 7 is inserted into the plug-in frame 8.
