[0073] In the present embodiment, the number of the positioning column 723 can be one or more. Similarly, the number of the positioning hole 7314 can also be one or more. The number of the positioning hole 7314 is the same as the number of the positioning column 723, and the inner diameter size of the positioning hole 7314 is matched with the outer diameter size of the positioning column 723.

[0074] When the shell 731 and the mounting seat 72 are mounted, the positioning column 723 is inserted into the positioning hole 7314, thereby realizing the positioning connection of the shell 731 and the mounting seat 72, which helps to improve the assembly efficiency of the shell 731 and the mounting seat 72.

[0075] Please refer to Figure 2 , Figure 3 and Figure 7 According to some embodiments of the present application, the number of the positioning column 723 is at least two, and the at least two positioning columns 723 are arranged at intervals along the outer circumferential side of the circuit board 732.
