Optionally, referring to fig. 2, fig. 3 and fig. 7, a notch 210 is formed in the PCB 21, the notch 210 is used for the second connection column 142 to pass through, so that the control board 30 is connected to the second connection column 142, the PCB 21 and the first connection column 141 may be connected by a screw, or may be fixed by clamping, so as to detachably connect the PCB 21 and the frame 14; the control board 30 and the second connecting column 142 can be connected by screws or fixed by clamping to realize the detachable connection of the control board 30 and the frame 14.

In one embodiment, referring to fig. 1, fig. 2 and fig. 7, the control board 30 is provided with an output terminal 31, and the output terminal 31 is used for connecting an external circuit to supply power to the external circuit. Specifically, the output terminal 31 is located on a side of the control board 30 away from the PCB board 21, which facilitates connection of an external circuit to the output terminal 31. Alternatively, the output terminal 31 includes a positive output terminal electrically connected to the positive input terminal of the control board 30 and a negative output terminal electrically connected to the negative input terminal of the control board 30, so that power can be supplied to the external circuit when the external circuit connects the positive output terminal and the negative output terminal.

Alternatively, the structure of the output terminal 31 may be the same as that of the electrical connection member 22. This is advantageous in reducing the production cost.

Optionally, the signal input terminal 32 includes a signal connection terminal located on a side of the control board 30 close to the PCB board 21, and the signal connection terminal is detachably connected to the signal connector 214. Therefore, the detachable connection of the signal connection terminal and the signal connector 214 is utilized, so that the installation and the detachment of the control board 30 and the switching assembly 20 are convenient, and the maintenance is convenient. Specifically, the signal connection terminal and the signal connector 214 may be connected by plugging, so as to facilitate connection conduction and disconnection.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
