[0042] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0044] An embodiment of the present application provides a HVAC system, which may include air conditioning, multi-split units, heat pumps, and other systems for heating or cooling, but the embodiment of the present application does not limit this.

[0045] HVAC systems include compressor components, see Figure 1 , Figure 1 This is a front schematic diagram of a compressor assembly 1 provided in an embodiment of the present application. The compressor assembly 1 includes a connector 10, a compressor 20 and a seal 30.

[0046] See also Figure 2 and Figure 3 , Figure 2 for Figure 1 Schematic diagram of the cross section in the AA direction, Figure 3 for Figure 2 1 is a cross-sectional exploded schematic diagram of the connector 10 and the sealing member 30, the connector 10 includes a housing 11, and the housing 11 is formed with a first port 1111. The compressor 20 includes a casing 24, the connector 10 is located outside the casing 24, and the first port 1111 of the housing 11 faces the casing 24. The sealing member 30 includes a sealing gasket 31, the sealing gasket 31 is located between the connector 10 and the casing 24, and the sealing gasket 31 is provided with a first mounting hole 311 communicating with the first port 1111.

[0047] The seal 30 for sealing the connector 10 and the compressor 20 is independent of the connector 10 and the compressor 20, so that the seal 30 can be independently molded, which can simplify the molding difficulty of the seal 30 and improve the product yield. Further, the seal 30 includes a sealing gasket 31, which is located between the connector 10 and the housing 24 of the compressor 20, and can achieve the sealing between the connector 10 and the compressor 20. A first mounting hole 311 is provided on the sealing gasket 31, which is convenient for locating the installation position of the seal 30 on the compressor 20, and is convenient for the connector 10 and the compressor 20 to be connected after passing through the first mounting hole 311, etc.

[0048] Furthermore, the sealing member 30 further includes a sealing ring 32, a sealing gasket 31 is located between the connector 10 and the housing 24, and the sealing gasket 31 is provided with a first mounting hole 311 connected to the first port 1111. The sealing ring 32 is connected to the sealing gasket 31 and protrudes from the side of the sealing gasket 31 close to the connector 10, the sealing ring 32 is arranged around the first mounting hole 311, and the sealing ring 32 passes through the first port 1111 and is located in the housing 11 and fits with the inner wall of the housing 11. In this way, the sealing ring 32 passes through the first port 1111 and is located in the housing 11 and fits with the inner wall of the housing 11, and the circumferential sealing with the connector 10 can be achieved. That is, the present application can not only achieve the sealing between the connector 10 and the compressor 20 through the sealing gasket 31, but also achieve the circumferential sealing with the connector 10 through the sealing ring 32, thereby improving the sealing performance of the compressor assembly 1.

[0049] See also Figure 3 , the inner wall of the sealing ring 32 is smoothly connected with the inner wall of the first mounting hole 311 formed by the sealing gasket 31. In this way, it is convenient for the connector 10 and the compressor 20 to be connected after passing through the first mounting hole 311 and the sealing ring 32. Furthermore, when observing along the first mounting hole 311, the inner wall of the sealing ring 32 and the inner wall of the first mounting hole 311 formed by the sealing gasket 31 can roughly overlap, so as to facilitate the connection between the connector 10 and the compressor 20 after passing through the first mounting hole 311 and the sealing ring 32 and facilitate the molding of the seal 30.

[0050] The seal 30 can be any device with sealing performance. In the embodiment of the present application, the seal 30 is a device with elasticity and high heat resistance, wherein the seal 30 has elasticity, so that when the connector 10 is connected to the compressor 20, the seal 30 can be in a compressed state to improve the tightness of the connection between the connector 10 and the compressor 20; and the seal 30 has high heat resistance, which can prevent the seal 30 from being damaged by the surface heat of the compressor 20, and can improve the service life of the seal 30. Specifically, the seal 30 can be a silicone rubber seal, which has low cost and is elastic and highly heat-resistant.

[0051] The sealing gasket 31 is provided with a first mounting hole 311, which is convenient for positioning the mounting position of the sealing member 30 on the compressor 20, and for connecting the connector 10 and the compressor 20 through the first mounting hole 311. For example, the compressor terminal 21 of the compressor 20 is electrically connected to the connector terminal 12 of the connector 10 after passing through the first mounting hole 311. Figure 2 and Figure 3The connector 10 includes a connector terminal 12 located in the housing 11, and the compressor 20 includes a compressor terminal 21 installed in the housing 24. At least a portion of the compressor terminal 21 protrudes outside the housing 24. The compressor terminal 21 passes through the first mounting hole 311 and the sealing ring 32 to be electrically connected to the connector terminal 12 in the housing 11. In this way, the setting of the sealing gasket 31 can prevent the refrigerant from entering the connector terminal 12 and the compressor terminal 21 when the compressor 20 uses R290 refrigerant, flammable and explosive refrigerant, or combustible refrigerant, and prevent the connector terminal 12 from igniting when the compressor terminal 21 is connected.

[0052] See also Figure 2 and Figure 3 The compressor 20 may further include a terminal seat 23 for mounting the compressor terminal 21, wherein the terminal seat 23 is mounted on the housing 24 and at least partially protrudes from the housing 24. The terminal seat 23 is provided to facilitate the installation of the compressor terminal 21.

[0053] Part of the terminal seat 23 is located in the first mounting hole 311 and fits with the inner wall of the first mounting hole 311 formed by the sealing gasket 31. In this way, the sealing performance of the sealing member 30 can be improved. Furthermore, the terminal seat 23 can also be partially located in the sealing ring 32 and fit with the inner wall of the sealing ring 32 to further improve the sealing performance of the sealing member 30.

[0054] See also Figure 2 and Figure 3 The housing 11 has a first end surface 114, and the first end surface 114 is formed with a first port 1111. The connector 10 further includes a convex rib 16, which is connected to the first end surface 114 and protrudes from the first end surface 114. The convex rib 16 is arranged around the first port 1111, and the convex rib 16 abuts against the sealing gasket 31. The convex rib 16 abuts against the sealing gasket 31. Compared with the abutment of the first end surface 114 against the sealing gasket 31, since the contact area between the convex rib 16 and the sealing gasket 31 is smaller, the convex rib 16 is easier to squeeze the sealing gasket 31 to compress and deform it, so as to achieve a closer contact between the sealing gasket 31 and the connector 10 and the compressor 20, and a better sealing effect.

[0055] See also Figure 4 , Figure 4 for Figure 3 In the enlarged schematic diagram of the structure at M in the middle, the rib 16 includes a connecting portion 161 connected to the first end surface 114 and an abutting portion 162 away from the first end surface 114, and the connecting portion 161 is connected to the abutting portion 162. Both the connecting portion 161 and the abutting portion 162 are arranged around the first port 1111.

[0056] In some embodiments, the width of the abutment portion 162 along the radial direction of the first port 1111 gradually decreases in the direction from the connection portion 161 to the abutment portion 162. In the rib 16, the abutment portion 162 contacts the sealing gasket 31 on the side away from the connection portion 161. The above design can reduce the contact area between the abutment portion 162 and the sealing gasket 31, so that the abutment portion 162 can more easily squeeze the sealing gasket 31 to compress and deform it, thereby achieving a closer contact between the sealing gasket 31 and the connector 10 and the compressor 20, and improving the sealing performance. In other embodiments, the width of the abutment portion 162 along the radial direction of the first port 1111 remains unchanged in the direction from the connection portion 161 to the abutment portion 162, which simplifies the manufacturing difficulty of the abutment portion 162 and reduces the manufacturing cost of the abutment portion 162.

[0057] It should be noted that, in the direction from the connecting portion 161 to the abutting portion 162 , the radial width of the abutting portion 162 along the first port 1111 may gradually increase, or first increase and then decrease, or first decrease and then increase, etc., and this is not limited.

[0058] In some embodiments, the width of the connecting portion 161 along the radial direction of the first port 1111 gradually decreases in the direction from the connecting portion 161 to the abutting portion 162. At this time, if the width of the abutting portion 162 along the radial direction of the first port 1111 gradually decreases in the direction from the connecting portion 161 to the abutting portion 162, the transition between the connecting portion 161 and the abutting portion 162 can be made smoother. In other embodiments, the width of the connecting portion 161 along the radial direction of the first port 1111 remains unchanged in the direction from the connecting portion 161 to the abutting portion 162. In this way, the connection between the connecting portion 161 and the housing 11 can be ensured to be stable.

[0059] In the embodiment of the present application, in the direction from the connecting portion 161 to the abutting portion 162 , the radial width of the connecting portion 161 along the first port 1111 may gradually increase, or first increase and then decrease, or first decrease and then increase, etc., without limitation.

[0060] The connector 10 may include one convex rib 16, or may include at least two convex ribs 16. If the connector 10 includes at least two convex ribs 16, the at least two convex ribs 16 are arranged at intervals along the radial direction of the first port 1111. Each convex rib 16 can squeeze the sealing gasket 31, so that the sealing gasket 31 is more closely contacted with the connector 10 and the compressor 20 at the convex rib 16, that is, the provision of at least two convex ribs 16 can achieve a closer contact between the sealing gasket 31 and the connector 10 and the compressor 20 at multiple locations, thereby improving the sealing performance.

[0061] In some embodiments, if the connector 10 includes at least two ribs 16, see Figure 4, the height of each rib 16 protruding from the first end surface 114 can be substantially equal. In this way, when the outermost rib 16 squeezes the sealing gasket 31, it can be roughly inferred that each rib 16 has squeezed the sealing gasket 31, simplifying the difficulty of connection and sealing. Figure 5 , Figure 5 yes Figure 3 The enlarged schematic diagram of an alternative solution of the structure at M in the middle, if the connector 10 includes at least two convex ribs 16, the height of each convex rib 16 protruding from the first end surface 114 can be gradually reduced along the radial direction of the first port 1111 and from the outside to the inside. In this way, the convex rib 16 located on the outermost side has the greatest degree of compression on the sealing gasket 31 and the best sealing performance; while the convex rib 16 located on the inner side gradually reduces the degree of compression on the sealing gasket 31, and the sealing performance gradually weakens, which can reduce the connection force required when the connector 10 and the compressor 20 are close to each other, reduce the difficulty of connection, and ensure the sealing performance between the connector 10 and the compressor 20.

[0062] It should be noted that if the connector 10 includes at least two ribs 16 , the height of each rib 16 protruding from the first end surface 114 along the radial direction of the first port 1111 and from the outside to the inside may also change alternately from decreasing to increasing, and this is not limited.

[0063] If the connector 10 includes at least two ribs 16 , each rib 16 may include the aforementioned connecting portion 161 and abutting portion 162 , which is not limited thereto.

[0064] The rib 16 and the housing 11 may be an integrated structure to simplify the assembly process of the connector 10 and improve assembly efficiency. The rib 16 and the housing 11 may also be detachably connected, for example, by snapping, bonding, etc., so that the rib 16 can be replaced to reduce replacement costs.

[0065] See also Figures 6 to 9 , Figure 6 for Figure 1 A schematic top view of a compressor assembly 1 is shown. Figure 7 yes Figure 6 Schematic diagram of the cross section along the BB direction. Figure 8 for Figure 7 The exploded cross-sectional view of the connector 10 and the seal 30 is shown in FIG. Fig. 9 yes Figure 1The exploded schematic diagram of the compressor assembly 1 is shown, and the connector 10 also includes a first connector 13, which is located on one side outside the housing 11 and installed on the housing 11. The compressor 20 also includes a second connector 22 installed on the casing 24, and at least part of the second connector 22 is located outside the casing 24. The sealing gasket 31 is formed with a second mounting hole 312, and the second connector 22 passes through the second mounting hole 312 to connect with the first connector 13. The second mounting hole 312 can be provided to locate the installation position of the sealing member 30 on the compressor 20, thereby improving the sealing performance.

[0066] The second connector 22 passes through the second mounting hole 312 to connect with the first connector 13. The second connector 22 passes through the second mounting hole 312 and the connecting hole 133 formed by the first connector 13 and then connects with the locking member 40. In this way, the connector 10 and the compressor 20 can be connected and fixed. The second connector 22 and the locking member 40 can be connected by threads. For example, the locking member 40 includes a nut, and the second connector 22 is provided with threads. The second connector 22 passes through the second mounting hole 312 and the connecting hole 133 and is threadedly connected and fixed with the nut. By tightening the nut, the distance between the compressor 20 and the connector 10 can be shortened. Of course, the second connector 22 extending into the connecting hole 133 can also be connected to the inner wall of the connecting hole 133 by means of snap-fitting, etc., and this is not limited.

[0067] In some embodiments, the connector 10 may include a first connector 13, the compressor 20 may include a second connector 22, and the first connector 13 is connected to the second connector 22. In this way, the connection process between the connector 10 and the compressor 20 can be simplified, the connection efficiency can be improved, and the volume of the connector 10 can be reduced.

[0068] It should be noted that the connector 10 and the compressor 20 are connected via a first connector 13 and a second connector 22, and the first connector 13 is located on one side outside the housing 11. When the connector 10 and the compressor 20 are connected, the sealing gasket 31 may rebound and recover due to less force on the side of the first port 1111 away from the first connector 13, causing the side of the housing 11 away from the first connector 13 to tilt up, affecting the sealing performance of the sealing gasket 31. At this time, since the sealing member 30 also includes a sealing ring 32, when the housing 11 tilts up, the sealing ring 32 can be deformed on the side of the housing 11 away from the first connector 13 to be tightly connected to the housing 11, so as to improve the problem of weakened sealing performance of the sealing gasket 31 caused by the tilting of the housing 11.

[0069] In other exemplary solutions, the connector 10 includes at least two first connectors 13, which are arranged at intervals in the circumferential direction of the housing 11; the compressor 20 includes at least two second connectors 22, which are connected to the first connectors 13 in a one-to-one correspondence. In this way, the connection between the connector 10 and the compressor 20 can be achieved at multiple locations in the circumferential direction of the housing 11, which can improve the problem of the connector 10 being warped on the opposite side of the connector 10 fixed to the compressor 20 due to the unilateral fixation of the connector 10 and the compressor 20.

[0070] Among them, at least two first connectors 13 can be arranged non-centrally symmetrically or centrally symmetrically in the circumference of the housing 11. If at least two first connectors 13 are arranged non-centrally symmetrically in the circumference of the housing 11, when the connector 10 is connected to the compressor 20, only in one case can each first connector 13 and each second connector 22 be connected one-to-one, which can achieve a foolproof effect. If at least two first connectors 13 are arranged centrally symmetrically in the circumference of the housing 11, the structure of the connector 10 can be more regular.

[0071] Next, the connector 10 will be further described.

[0072] See also Figures 7 to 11 , Fig.10 yes Figure 1 An exploded schematic diagram of the connector 10 in the compressor assembly 1 is shown. Fig.11 yes Figure 1 The bottom view of the connector 10 in the compressor assembly 1 is shown. The connector terminal 12 can be any terminal, and the compressor terminal 21 can be any terminal, as long as the compressor terminal 21 and the connector terminal 12 can be electrically connected.

[0073] For example, one of the connector terminal 12 and the compressor terminal 21 may be a male terminal, and the other may be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, the compressor terminal 21 is a male terminal, the connector terminal 12 is formed with a plug hole, and at least a portion of the compressor terminal 21 is inserted into the plug hole and electrically connected to the connector terminal 12. That is, when the connector terminal 12 is connected to the compressor terminal 21, at least a portion of the compressor terminal 21 is surrounded by the connector terminal 12, which can improve the connection reliability between the connector terminal 12 and the compressor terminal 21.

[0074] The housing 11 is formed with a first chamber 1117, the first chamber 1117 is located in the first port 1111, and the first chamber 1117 is communicated with the first port 1111, and the connector terminal 12 is located in the first chamber 1117. In this way, the compressor terminal 21 can extend into the first chamber 1117 through the first port 1111 and be electrically connected to the connector terminal 12. The provision of the first chamber 1117 is conducive to positioning the assembly position of the connector terminal 12 in the housing 11.

[0075] The connector 10 may include a plurality of connector terminals 12, and the housing 11 may be formed with a plurality of first chambers 1117, and each connector terminal 12 may be located in each first chamber 1117 in a one-to-one correspondence. For example, the connector 10 may include two connector terminals 12, and the housing 11 may be formed with two first chambers 1117; or, the connector 10 may include three connector terminals 12, and the housing 11 may be formed with three first chambers 1117, and so on, without limitation.

[0076] It is understandable that when the connector 10 includes a plurality of connector terminals 12 , the compressor 20 includes a plurality of compressor terminals 21 equal in number to the plurality of connector terminals 12 , and each compressor terminal 21 is electrically connected to each connector terminal 12 in a one-to-one correspondence.

[0077] The housing 11 is formed with a second chamber 1118, which extends from the first end surface 114 toward the other side of the housing 11, and the second chamber 1118 forms a first port 1111 on the side of the first end surface 114. When the connector 10 is connected to the compressor 20, the second chamber 1118 is closer to the compressor 20 than the first chamber 1117. The provision of the second chamber 1118 can reduce the docking area between the connector 10 and the compressor 20, and reduce the precision design requirements of the docking surface of the connector 10.

[0078] Observing along the first port 1111, the cross-sectional profiles of all the first chambers 1117 are located within the cross-sectional profiles of the second chamber 1118. In this way, when the connector 10 includes a plurality of connector terminals 12 and the compressor 20 includes a plurality of compressor terminals 21, when the compressor terminals 21 are connected to the connector terminals 12, all the compressor terminals 21 can pass through the second chamber 1118 and reach the corresponding first chamber 1117 to achieve electrical connection with the corresponding connector terminals 12.

[0079] The sealing ring 32 may be located in the second chamber 1118 of the housing 11 and fit against the inner wall of the second chamber 1118. The terminal seat 23 may be located in the second chamber 1118.

[0080] In some embodiments, the housing 11 may include a first housing portion 111 and a second housing portion 112, wherein the first housing portion 111 is formed with a first port 1111, a first chamber 1117, and a second port 1114 communicating with the first chamber 1117, the connector terminal 12 is mounted on the first housing portion 111 via the second port 1114, and the second housing portion 112 is connected to the first housing portion 111. Disassembling the housing 11 into the first housing portion 111 and the second housing portion 112 is beneficial to assembling the connector terminal 12. The first housing portion 111 may be provided with a second chamber 1118.

[0081] The heat resistance of the first housing portion 111 is higher than that of the second housing portion 112. Compared with the second housing portion 112, the first housing portion 111 is less likely to deform under high temperature conditions. Thus, the first port 1111 is disposed on the first housing portion 111. When the connector 10 is connected to the compressor 20, the first housing portion 111 is close to the compressor 20. The first housing portion 111 has high heat resistance, which can prevent the internal connector terminal 12 from being softened by high temperature, thereby extending the service life of the connector terminal 12.

[0082] The seal 30 is located between the first housing portion 111 and the casing 24 of the compressor 20. In this way, even if the heat on the surface of the compressor 20 is transferred to the seal 30 and the first housing portion 111, the first housing portion 111 is not easily deformed, and thus can provide a stable support effect for the seal 30, thereby ensuring the sealing performance between the compressor 20 and the connector 10, and ensuring the stability of the connection between the compressor 20 and the connector 10.

[0083] The first housing portion 111 may be made of a high heat-resistant material, for example, the first housing portion 111 may include at least one of PBT (poly butylene terephthalate) and GF (glass fiber). In the embodiment of the present application, the first housing portion 111 is made of PBT+30% GF, which is a high temperature resistant and fireproof material, and can prevent the connector terminal 12 from softening during operation.

[0084] The second housing portion 112 may cover the second port 1114 and the connector terminal 12. The second port 1114 is provided to facilitate the installation of the connector terminal 12 in the housing 11, and the second housing portion 112 covers the second port 1114 and the connector terminal 12, so that when the connector terminal 12 and the compressor terminal 21 are connected, both are wrapped by the housing 11 of the connector 10, avoiding the presence of refrigerant near the two and the ignition problem when the connector terminal 12 and the compressor terminal 21 are connected. Among them, the first housing portion 111 may have a first end surface 114.

[0085] The second housing portion 112 may include an injection-molded housing portion connected to the first housing portion 111, and / or the second housing portion 112 may include a glue-filled housing portion connected to the first housing portion 111. The injection-molded housing portion is formed by an injection molding process, and the injection-molded housing portion is connected to the first housing portion 111, and the injection-molded housing portion is at least an integrally-molded structure with the first housing portion 111. Specifically, after the first housing portion 111 is molded, at least the first housing portion 111 is placed in a mold to participate in constructing a cavity for molding the injection-molded housing portion, and then a molding material is injected into the cavity to obtain the injection-molded housing portion.

[0086] The glue-filled housing portion is formed by a glue-filling process, and the glue-filled housing portion is connected to the first housing portion 111, so the glue-filled housing portion is at least an integrally molded structure with the first housing portion 111. Specifically, the first housing portion 111 is formed with a molding groove, and at least the molding groove participates in constructing a glue-filling groove for molding the glue-filled housing portion, and then the molding material is injected into the glue-filling groove to obtain the glue-filled housing portion.

[0087] In summary, whether the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, the second housing portion 112 and the first housing portion 111 can be formed as an integral structure, which can improve the tightness of the connection between the second housing portion 112 and the first housing portion 111, and improve the sealing between the second housing portion 112 and the first housing portion 111, compared with the second housing portion 112 and the first housing portion 111 being formed independently and then assembled. The second housing portion 112 of the connector 10 is sealed to the first housing portion 111, and when the connector 10 is connected to the compressor 20, the first housing portion 111 and the surface of the compressor 20 are sealed due to the presence of the seal 30, so that the overall sealing of the connector 10 can be improved.

[0088] The second shell part 112 may be made of a sealing rubber shell, which has a high sealing performance. The second shell part 112 may be elastic or inelastic, and may be flexibly designed according to actual needs. In the embodiment of the present application, the second shell part 112 may be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing performance. The second shell part 112 may be made of plastic or silicone, which is not limited.

[0089] In order to improve the connection reliability between the second housing part 112 and the first housing part 111, one of the second housing part 112 and the first housing part 111 may be provided with a hook 1121, and the other may be provided with a slot 1115 adapted to the hook 1121, and the hook 1121 is located in the slot 1115. The second housing part 112 and the first housing part 111 can be hooked by the hook 1121 and are not easy to be separated. It can be understood that the second housing part 112 may be provided with a hook 1121, and the first housing part 111 may be provided with a slot 1115; or the second housing part 112 may be provided with a slot, and the first housing part 111 may be provided with a hook, and this is not limited.

[0090] It is understandable that the second housing portion 112 can be integrally formed as an injection-molded housing portion, or the second housing portion 112 can be integrally formed as a glue-potted housing portion, so as to simplify the processing technology of the second housing portion 112 and reduce the manufacturing cost of the connector 10 .

[0091] The connector 10 also includes a cover, which covers the second port 1114, and the second housing portion 112 covers the cover. Under the cover, impurities such as water vapor and dust can be prevented from entering the first housing portion 111, which would affect the performance of the connector terminal 12. When the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, under the cover, the molding material of the second housing portion 112 will not pass through the second port 1114 to reach the connector terminal 12, and wrap the connector terminal 12, thereby ensuring effective electrical connection between the connector terminal 12 and the compressor terminal 21.

[0092] The connector terminal 12 and the cover member may be in contact or have a gap therebetween. If there is a gap between the connector terminal 12 and the cover member, the connector terminal 12 can be deformed toward the gap when plugged into the compressor terminal 21 to avoid damage to the connector terminal 12 and the compressor terminal 21 due to hard plugging.

[0093] The cover assembly may include a cover plate 14 , the cover plate 14 covers the second port 1114 and the connector terminal 12 , and the second housing portion 112 covers the cover plate 14 .

[0094] One of the cover plate 14 and the first housing portion 111 may be provided with a limiting protrusion 141, and the other may be provided with a limiting groove 1116, and the limiting protrusion 141 is located in the limiting groove 1116. The provision of the limiting protrusion 141 and the limiting groove 1116 can position the cover plate 14 and the first housing portion 111 when they are assembled, which is conducive to improving the assembly efficiency of the cover plate 14 and the first housing portion 111. It can be understood that the limiting protrusion 141 can be provided on the cover plate 14, and the limiting groove 1116 can be provided on the first housing portion 111; or, the limiting groove 1116 can be provided on the cover plate 14, and the limiting protrusion 141 can be provided on the first housing portion 111, and this is not limited. In the embodiment of the present application, a limiting protrusion 141 is provided on the cover plate 14, and a limiting groove 1116 is provided on the first shell portion 111. Since the cover plate 14 is relatively thin, providing the limiting protrusion 141 on the cover plate 14 is more conducive to improving the structural strength of the cover plate 14 than providing the limiting groove 1116.

[0095] If the housing 11 is formed with a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0096] The connector 10 also includes a connecting wire 15, which is electrically connected to the connector terminal 12, and is used to realize signal interaction between the compressor 20 and the outside world when the connector terminal 12 is connected to the compressor terminal 21. Among them, one end of the connecting wire 15 connected to the connector terminal 12 is wrapped by the second shell part 112 to improve the connection reliability between the connecting wire 15 and the connector terminal 12, and improve the sealing of the connector 10. Specifically, when the second shell part 112 includes an injection molding shell part and / or a glue pouring shell part, the second shell part 112 can directly wrap one end of the connecting wire 15 connected to the connector terminal 12 during injection molding and / or glue pouring. If the connector 10 includes multiple connector terminals 12, the connecting wire 15 is electrically connected to the multiple connector terminals 12.
