Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
referring to fig. 1-5, a motor harness sealing structure comprises a motor housing, wherein the motor housing comprises a main body 1 and a side cover plate 2 arranged on the side surface of the main body 1, a plurality of first through holes 21 for a line to pass through are formed in the side cover plate 2, the first through holes 21 penetrate through the side cover plate 2, the outer end of the first through holes is communicated with the outside of the motor housing, and the inner end of the first through holes are communicated with the inner cavity of the motor housing, so that a harness can enter the inside of the motor housing through the first through holes 21 and is connected with corresponding parts in the inside.
Alternatively, a wire harness mating portion 22 may be formed on the side cover 2, and the first through hole 21 is formed at the wire harness mating portion 22, where the wire harness mating portion 22 may be integrally formed with the side cover 2, so as to provide sufficient space for the first through hole 21 to be formed.
In this embodiment, the side cover 2 has a receiving notch 23, the receiving notch 23 is circumferentially disposed at an opening at an outer end of the first through hole 21, an inner end of the receiving notch is connected to an opening at an outer end of the first through hole 21, and a diameter of the receiving notch 23 increases gradually from the inner end to the outer end, alternatively, the receiving notch 23 is tapered, and a wall of the receiving notch 23 is an inclined wall or an arc wall.
