And through the abutting cooperation between the at least one convex rib 123 and the first sealing rib, the sealing effect between the terminal cover 120 and the shell 110 can be significantly improved.

[0100] In addition, since the at least one convex rib 123 is located on the outer circumferential side of the first through hole 121 and / or the at least one convex rib 123 is located on the outer circumferential side of the second through hole 122, that is, the convex rib 123 is arranged on the outer circumferential side of the position of the terminal cover 120 prone to water and moisture, while realizing effective compression and sealing between the terminal cover 120 and the first sealing member 130, the water vapor or water flow in the external environment is prevented from entering the terminal cover 120 from the first through hole 121 or the second through hole 122, the sealing and protection effect of the terminal cover 120 is significantly improved, and compared with the related art of sealing the outer edge of the lead-out portion, only the abutting sealing is performed on the outer circumferential side of the first through hole 121 and / or the second through hole 122, which can effectively reduce the space layout of the lead-out portion and meet the dustproof and waterproof requirements of small space structure.

Since the outer wall of the at least one convex rib 123 is an arc-shaped wall, even if there is a certain difference in the locking force during the installation of the terminal cover 120, sufficient contact between the convex rib 123 and the first sealing member 130 can be ensured, a compression fit is achieved, and the installation difficulty is reduced. Moreover, the contact area between the at least one convex rib 123 and the first sealing member 130 can be increased, the sealing effect is improved, and the dustproof and waterproof requirements are ensured.

[0110] Since the at least one convex rib 123 abuts against the first sealing member 130, the gap between the outer wall of the shell 110 and the terminal cover 120 can be sealed, realizing waterproof and dustproof design of the lead-out wire part of the compressor, and ensuring normal work of the compressor in special working conditions such as humidity. And through the compression fit between the at least one convex rib 123 and the first sealing rib, the sealing effect between the terminal cover 120 and the shell 110 can be significantly improved.
