[0047] The embodiment provides a compressor wiring waterproof structure. Figures 1 to 13 As shown in the figure, the compressor wiring waterproof structure comprises a shell 1, a box body 2, a box cover 3 and an elastic sealing ring 4. The shell 1 is used for accommodating working parts of the compressor, a mounting hole 101 is formed in the side wall of the shell 1, and a connector 12 is mounted in the mounting hole 101; the box body 2 is fixed to the shell 1, the connector 12 extends into the box body 2, an outer edge of the box body 2 is provided with a plug-in part 21; the box body 2 is plugged with the inner side wall of the box cover 3 through the plug-in part 21, the inner side wall of the box cover 3 is provided with an embedding groove 31, the elastic sealing ring 4 is embedded in the embedding groove 31, and the end of the plug-in part 21 abuts against the elastic sealing ring 4; a cable extends into the box body 2 and is electrically connected with the compressor through the connector 12.

[0048] In the embodiment, the working parts (motor, pump body, etc.) of the compressor can be accommodated in the shell 1, and the connector 12 (i.e., the terminal post) on the side of the compressor is fixedly connected with the mounting hole 101 of the shell 1. The shell 1 can preliminarily isolate the working parts of the compressor from the external environment. In addition, the box body 2 is fixed on the shell 1, the box cover 3 is arranged on the box body 2, the connector 12 extends into the box body 2, and the cable extends into the box body 2 to realize electrical connection with the compressor through the connector 12. The box body 2 and the box cover 3 can reliably and effectively protect the connector 12 and effectively isolate the external environment. Further, the insertion part 21 of the box body 2 is inserted with the inner side wall of the box cover 3, and the insertion part 21 abuts against the elastic sealing ring 4 in the box cover 3, so as to form a double-layer waterproof sealing structure when the box body 2 and the box cover 3 are closed, effectively guaranteeing the waterproof sealing effect of the connector 12 part, thereby avoiding the connector 12 from contacting the external water vapor, and meeting the higher waterproof grade requirement of the large-displacement and large-size terminal post side-by-side compressor.

[0049] In the embodiment, the material of the elastic sealing ring 4 is rubber. Rubber has good sealing performance and low cost, and is easy to produce.

[0050] In the embodiment, as shown in Figures 2 to 4 The side wall of the shell 1 is provided with a connecting boss 11, the connecting boss 11 has a supporting plane 111, the mounting hole 101 is arranged on the supporting plane 111, and the box body 2 is fixed on the supporting plane 111. Specifically, the supporting plane 111 can be attached to the corresponding mounting plane of the box body 2, thereby providing reliable mounting space for the box body 2. Specifically, the box body 2 is correspondingly provided with a connecting hole 23, the connecting hole 23 is arranged corresponding to the mounting hole 101, and the connector 12 extends into the box body 2 through the mounting hole 101 and the connecting hole 23. Alternatively, the supporting plane 111 and the corresponding mounting plane of the box body 2 can be fixed by welding operation.

[0051] Alternatively, the outer diameter of the insulating seat of the mounting hole 101 connected with the connector 12 is a clearance fit.

[0052] The specific structure of the connector 12 for electrically connecting the compressor and the cable is prior art.

[0053] In the embodiment, as shown in Figures 4 to 11As shown, the size of the elastic sealing ring 4 in the direction perpendicular to the inner side wall of the box cover 3 is smaller than the width of the embedding groove 31. In this way, when the elastic sealing ring 4 is installed, the elastic sealing ring 4 is extruded and deformed by the embedding groove 31 to present a partially inclined posture, so that when the box cover 3 is assembled with the box body 2, the contact between the insertion part 21 of the box body 2 and the elastic sealing ring 4 changes from the overall surface contact of the end of the insertion part 21 to the contact with the inclined part of the elastic sealing ring 4 first, so that the pressure of the elastic sealing ring 4 by the end of the insertion part 21 changes from uniform distribution to most of the pressure concentrated on the inclined part of the elastic sealing ring 4, thereby enhancing the pressure of the insertion part 21 on the inclined part of the elastic sealing ring 4 and improving the sealing therebetween, and improving the effectiveness of the second layer of sealing structure.

[0054] Specifically, referring to Figure 11 As shown, the first side of the groove bottom of the embedding groove 31 is arranged towards the inner side wall of the box cover 3, and the second side of the groove bottom of the embedding groove 31 is arranged away from the inner side wall of the box cover 3; the groove bottom of the embedding groove 31 comprises a first groove bottom part 311 and a second groove bottom part 312 arranged in sequence from the first side to the second side, the first groove bottom part 311 is perpendicular to the inner side wall of the box cover 3, and the second groove bottom part 312 is arranged obliquely towards the direction close to the slot opening of the embedding groove 31; the included angle θ between the first groove bottom part 311 and the second groove bottom part 312 is arranged in the range of 5°-50°. Specifically, the included angle θ between the first groove bottom part 311 and the second groove bottom part 312 needs to be arranged in a reasonable range, if the included angle θ is too small, the elastic sealing ring 4 is not inclined enough to change the pressure of the insertion part 21 on the elastic sealing ring 4 from uniform distribution to most of the pressure concentrated on the inclined part of the elastic sealing ring 4, and the sealing cannot be effectively improved; if the included angle θ is too large, the embedding effect of the elastic sealing ring 4 is not good and the elastic sealing ring 4 is easy to fall out. Therefore, the included angle θ is arranged in the range of 5°-50°, which not only ensures that the elastic sealing ring 4 has a certain reasonable inclination to further improve the sealing when the insertion part 21 is inserted, but also ensures the reliable embedding of the elastic sealing ring 4 to avoid the elastic sealing ring 4 falling out of the embedding groove 31.

[0055] Further, the length of the first groove bottom part 311 is L1, and the thickness of the insertion part 21 is L2, and L1 and L2 satisfy: L1 Figure 11 As shown in the example, the length L1 of the first groove bottom part 311 is smaller than the thickness L2 of the insertion part 21, so that the end of the insertion part 21 away from the inner side wall of the box cover 3 can first contact the inclined part of the elastic sealing ring 4, effectively improving the sealing.

[0056] In this embodiment, continuing to refer to Figures 4 to 10As shown, the box cover 3 is provided with a clamping joint 32 on each side, and the box body 2 is provided with a clamping groove 22 corresponding to the clamping joint 32. Specifically, after the box cover 3 is covered on the box body 2, the clamping joint 32 is clamped in the corresponding clamping groove 22, thereby realizing reliable fixation between the box cover 3 and the box body 2, which is simple in structure and reliable and stable in connection.

[0057] Specifically referring to Figure 10 As shown, the clamping joint 32 includes a first end face 321 for abutting the clamping groove 22, and the length L3 of the first end face 321 satisfies L3>1mm. Specifically, the length of the sidewall of the clamping groove 22 in the direction of the first end face 321 is slightly greater than the length of the first end face 321. The length of the first end face 321 should not be set too large, otherwise the size of the box body 2 will be increased, and it should also not be set too small, otherwise the firmness and reliability of the clamping will be affected.

[0058] Further specifically, the clamping joint 32 further includes a second end face 322 which is inclinedly arranged away from the clamping groove 22, and the first end face 321 and the second end face 322 are connected by a round corner 323. By arranging the round corner 323, the clamping and dismounting between the clamping joint 32 and the clamping groove 22 can be facilitated.

[0059] In this embodiment, referring to Figures 4 to 6 As shown, the insertion part 21 is provided with a first hole part 211, and the box cover 3 is provided with a second hole part 33 corresponding to the first hole part 211. The first hole part 211 and the second hole part 33 jointly enclose a first through hole, and the cable is inserted into the box body 2 through the first through hole. In some other optional embodiments, the first through hole can be arranged on the box body 2 alone, or on the box cover 3 alone, as long as the cable can be inserted into the box body 2.

[0060] In this embodiment, referring to Figures 12 to 13 As shown, the compressor wiring waterproof structure further includes a sleeve 5, and the sleeve 5 has a fixing part 51. An insertion ring groove 511 is arranged on the outer sidewall of the fixing part 51, and the insertion ring groove 511 is inserted into the first through hole. The cable is inserted into the box body 2 through the sleeve 5. By arranging the sleeve, reliable sealing can be provided for the insertion part of the first through hole and the cable, and the overall waterproof performance is further improved. It is worth mentioning that the above-mentioned first through hole is arranged in the form of a first hole part 211 and a second hole part 33 jointly enclosing, and this split combination arrangement can be adapted to the insertion ring groove 511, thereby realizing reliable installation of the sleeve 5 and preventing it from falling off.

[0061] Further, the inner circumferential wall of the sleeve 5 is spaced apart with a plurality of elastic valves 52, the plurality of elastic valves 52 are collectively enclosed to form a second through hole 53 for the cable to pass through, the inner diameter of the sleeve 5 is D1, the hole diameter of the second through hole 53 is D2, the outer diameter of the cable is D3, D1, D2 and D3 satisfy: D2 < D3 < D1. Specifically, when the cable passes through the second through hole 53 to enter the inside of the box body 2, the plurality of elastic valves 52 are deformed, at this time, the hole diameter of the second through hole 53 increases to the outer diameter of the cable, so that the cable can pass into the second through hole 53, the end of the elastic valve 52 is tightly attached to the outer surface of the cable, so that the cable can be reliably and effectively sealed at the passing part. When the cable is taken out, the outer diameter of the second through hole 53 can return to D2 under the resetting action of the plurality of elastic valves 52.

[0062] Optionally, the material of the elastic valve 52 can be rubber.
