[0071] In the related art, the wire passing port of the electric control box is generally arranged on the side wall of the box body, in order to facilitate the arrangement of the wire passing port, the whole side wall of the box body generally has a high height dimension, therefore, in the wiring process of inserting the terminal of the cable into the terminal of the electric control board, the side wall of the box body is easy to hinder the hands of the operator.

[0072] The electric control box 100 of the embodiment of the present application is provided with the protruding structure 112 having the wire passing port 112a on the first box body 11, since the protruding structure 112 protrudes from the side wall 111b of the box main body 111 in the first direction, the height dimension of the side wall 111b in the first direction can be reduced as much as possible, and the terminal 22 also protrudes from the side wall 111b in the first direction, therefore, in the wiring process, the side wall 111b hardly hinders the hands of the operator, so that the convenience of wiring can be improved.
