Of course, the specific structure and shape of the control panel body 100 are not limited thereto, and technicians in this field can design the shape of the control panel body 100 according to needs.

[0035] In the present embodiment, a conductive part 120 is provided on the outer flange 110 of the control board body 100 or near the outer flange 110. The conductive part 120 includes a second connecting hole 121 opened near the outer flange 110 of the control board and a conductive structure 122 arranged in the second connecting hole 121. The conductive structure 122 is connected to the internal circuit of the control board body 100. Specifically, the conductive structure 122 of the present embodiment is a metal conductive protrusion arranged in the square second connecting hole 121. Preferably, in order to ensure the conductive connection stability between the connector 200 and the conductive structure 122, the number of conductive structures 122 of each conductive part 120 in the present embodiment is two. The two conductive structures 122 are respectively located on opposite sides of the second connecting hole 121. The two conductive structures 122 form a conductive track.
