In this embodiment, the housing may include multiple sections of open housings that are snap-fitted and assembled together, such as including a cover shell 11, a first side shell 12, and a second side shell 13.

[0028] On any side wall of the housing, there is a first terminal insertion surface 111. In this embodiment, the first terminal insertion surface 111 is one side wall of the cover shell 11, specifically the side wall of the cover shell 11 that is perpendicular to both the first side 12 and the second side shell 13. In other words, the first terminal insertion surface 111 is the front surface of the servo driver. Refer to Figure 3 As shown in the figure, on the first terminal insertion surface 111, there is a human-machine interaction module 20, and a first terminal group and a second terminal group that are parallel to each other and arranged on one side of the human-machine interaction module 20.
