DETAILED DESCRIPTION

(5) As shown in FIGS. 1 and 2, in the present disclosure, a compressor includes a compressor housing (not shown), an upper cover 1 and a lower cover (not shown). The upper cover 1 includes a wiring cover assembly.

(6) The wiring cover assembly is used to improve the sealing grade of the wiring portion of the compressor. The wiring cover assembly includes a gasket 2 and a housing 3. The housing 3 includes a wire outlet which is used for leading lead-out wires out of the compressor. The wire outlet includes a waterproof connector 31.

(7) The wiring cover assembly further includes a fasten assembly. The fasten assembly includes a screw 51 and a nut 52. The housing 3 is tightly pressed, by the fasten assembly, on the gasket 2 to form a closed space.

(8) The gasket 2 includes a rubber gasket. As shown in FIG. 3, the gasket 2 includes a boss 21. The raised outer edge is formed a closed curve which is interference fit to an inner wall of the housing 3. The waterproof performance of the wiring cover assembly is then further improved. The gasket 2 includes a central through-hole 22 used for fastening the gasket. The gasket 2 also includes two through-holes 23, 24. One through-hole 23 of the other two through-holes is used for installing a temperature actuated switch. Another through-hole 24 is used for sealing a wiring terminal. The sealed wiring terminal is used to couple electric wires of the electric source to make the compressor work.

(9) As shown in FIGS. 3 and 4, the top of the housing 3 includes a through-hole 32 used to fasten the housing 3. The wire outlet located on a side wall of the housing 3 includes a waterproof connector 31 which is used for leading lead-out wires out of the compressor.

(10) The screw 51 goes through the through-hole 32 of the housing 3 and the through-hole 22 of the gasket 2. The housing 3 is then fastened on the cover 1 by a nut 52. The nut 52 includes a cap nut which will further improve the waterproof performance of the wiring cover assembly. The waterproof connector 31 includes a round connector which is capable of coupling to other standard tubes for implementing waterproof. After the lead-out wires are assembled, the waterproof connector 31 is then sealed by thread sealant to seal the thread inside the waterproof connector 21.

(11) In another embodiment, in order to ensure the housing 3 is evenly and tightly pressed on the gasket 2, the wiring cover assembly further includes a cover plate 6 disposed on the housing 3. As shown in FIG. 1, specifically, the housing 3 is made of thinner material.

(12) The top of the housing 3 further includes humps 33, as shown in FIG. 4, which is used to fasten the cover plate 6. The screw 51 goes through the through-hole of the cover plate 6, the through-hole 32 of the top of the housing 3, the through-hole 22 of the gasket 2. The housing is then fixed on the upper cover 1 by the nut 52.

(13) In this embodiment, the cover plate 6 is made of metal, and also can be made of plastic or other materials.

(14) In practical production, it is difficult to assure the flatness of the housing 3 and the cover plate 6. Therefore, a rubber gasket is disposed between the housing 3 and the cover plate 6 to further improve the grade of waterproof of wiring cover assembly.

(15) A rubber gasket is also disposed between the cover plate 6 and the nut 52 to further improve the grade of waterproof of the wiring cover assembly.

(16) In this embodiment, the wiring cover assembly adopts the above structure and the grade of waterproof reaches IP67.

(17) The preferred embodiments of the present disclosure have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present disclosure without creative work. Therefore, any technical solution that can be obtained by a person who skilled in art through logical analysis, reasoning, or limited experimentation based on the concept of the present disclosure on the basis of the prior art shall fall within the protection scope determined by the claims.
