[0020] The utility model is further described in detail below in conjunction with the embodiments.

[0021] When implementing: Figure 1 to Figure 3As shown, a plug-in motor controller comprises a housing 1 with an open top and a controller module 5 installed in the housing 1, and a cover plate 2 is sealed on the opening of the housing 1; in this embodiment, the housing 1 is in the shape of a U-shaped groove, and the outer side surface and the outer bottom surface of the housing 1 are provided with fins 12 extending along the length direction, and sealing plates 4 are installed at both ends; the housing 1 has two opposite side walls with a limit strip 11 arranged opposite to each other, and the limit strip 11 is extended along the length direction of the housing 1 at the opening of the housing 1; the cover plate 2 has buckles arranged corresponding to the limit strip 11 on both sides, and is clamped on the limit strip 11. The two ends of the cover plate 2 have blind holes formed by inward drawing, and the sealing plate 4 has bolt holes arranged corresponding to the blind holes, and is connected to the blind holes by screws.

[0022] The controller module 5 includes a circuit board 51 installed at the bottom of the housing 1. A plurality of copper posts 52 for connecting a power source or a motor are vertically arranged on the circuit board 51. The cover plate 2 has a wiring hole corresponding to the copper posts 52. The copper posts 52 pass through the corresponding wiring hole in a sealed manner. The upper end of the copper posts 52 has a coaxially arranged threaded hole and is equipped with a bolt for fixing the wire. A connector 53 is sealedly penetrated on the cover plate 2, and the inner end of the connector 53 is electrically connected to the circuit board 51. In order to facilitate the connection between the connector on the cover plate and the circuit board 51, a male pin corresponding to the connector 53 is vertically arranged on the circuit board 51.
