[0088] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0089] When the following description refers to the accompanying 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 merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0090] Example 1

[0091] 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.

[0092] 1 , the HVAC system includes a connector 10 and a compressor 20, wherein the connector 10 is electrically connected to the compressor 20. The connector 10 and the compressor 20 are also fixedly connected to ensure the reliability of the electrical connection between the connector 10 and the compressor 20.

[0093] Referring to Figures 2 and 3, the connector 10 includes a housing 11 and a first connector 13. The housing 11 has a first end face 113 and a second end face 114 that are opposite each other along a first direction x. The second end face 114 is formed with a first port 1111. The first connector 13 and the housing 11 are arranged along a second direction y, which is perpendicular to the first direction x. The first connector 13 is connected to the housing 11. The first connector 13 has a first surface 131 and a second surface 132 that are opposite each other along the first direction x. The first surface 131 and the first end face 113 are located on one side of the connector 10 in the first direction x, while the second surface 132 and the second end face 114 are located on the other side of the connector 10 in the first direction x. The first connector 13 is formed with a connection hole 133 that extends along the first direction x. The ends of the connection hole 133 extend to the first surface 131 and the second surface 132, respectively. The second surface 132 includes a first area 1321 and a second area 1322 distributed on opposite sides of the connecting hole 133 along the second direction y. The first area 1321 is farther away from the housing 11 than the second area 1322 . At least one point of the first area 1321 protrudes from the second area 1322 .

[0094] The first connector 13 can be used to securely connect the connector 10 to the compressor 20. Furthermore, the first connector 13 is formed with a connecting hole 133, and the connector 10 and the compressor 20 can be securely connected via a second connector 22 that extends into the connecting hole 133. The connector 10 and the compressor 20 can be securely connected via the second connector 22 that extends into the connecting hole 133. The second connector 22 can extend through one side of the connecting hole 133 and connect with a locking member 40, thereby securing the connector 10 and the compressor 20. The second connector 22 and the locking member 40 can be threadedly connected. For example, the locking member 40 can include a nut, and the second connector 22 is threadedly connected to the nut after extending through the connecting hole 133. Tightening the nut can shorten the distance between the compressor 20 and the connector 10. Of course, the second connector 22 that extends into the connecting hole 133 can also be secured to the inner wall of the connecting hole 133 by snapping or other means, without limitation.

[0095] Because the first connector 13 and the housing 11 are arranged along the second direction y, the first connector 13 can only be connected and fixed to the compressor 20 on a single side of the connector 10. Since at least one point on the first region 1321 protrudes beyond the second region 1322, when the connector 10 is connected and fixed to the compressor 20, the first region 1321 will first contact the compressor 20. If the first region 1321 contacts the compressor 20, the compressor 20 will apply a first force F1 to the first connector 13 at the first region 1321. The first force F1 is directed from the compressor 20 to the first connector 13.

[0096] When the connector 10 is connected and fixed to the compressor 20, referring to Figure 4, the shell 11 and the first connecting member 13 can be roughly regarded as a lever structure with the second connecting member 22 extending into the connecting hole 133 as the fulcrum. In this way, if the first area 1321 is subjected to the first force F1, the end of the shell 11 away from the first connecting member 13 will be subjected to the second force F2, which can improve the problem of the second end surface 114 away from the end of the first connecting member 13 tilting, that is, improve the problem of the connector 10 tilting on the opposite side of the connector 10 fixed to the compressor 20 due to unilateral fixation.

[0097] 4 , any point on the right side of the lever that is subject to the first upward force F1 can cause the left side of the lever to be subject to the second downward force F2, thereby improving the problem of the second end face 114 tilting away from the end of the first connector 13. Therefore, any point on the first area 1321 that protrudes beyond the second area 1322 can improve the problem of the connector 10 tilting on the opposite side to the compressor 20 due to the unilateral fixation of the connector 10 and the compressor 20.

[0098] In an exemplary solution, referring to FIG. 3 , the second surface 132 may be an inclined surface inclined relative to the first direction x, so that the second surface 132 is flat and easy to process.

[0099] Furthermore, the acute angle θ1 between the second surface 132 and the first direction x is greater than or equal to 80° and less than or equal to 89.5°. By properly limiting the acute angle θ1 between the second surface 132 and the first direction x, the problem of the connector 10 warping on the side opposite to the compressor 20 due to unilateral fixation can be improved, while also ensuring that the inclination of the second surface 132 is appropriate, thereby preventing sharp corners that could cause accidental injury. The acute angle θ1 between the second surface 132 and the first direction x can be 80°, 82.5°, 85°, 87°, 89.5°, and so on, without limitation.

[0100] In another exemplary embodiment, referring to Figures 5 and 6 , the first connector 13 includes a connecting post 134 and a gasket 135. The connecting post 134 is connected to the housing 11 and has a first surface 131 and a third surface 1341 that oppose each other along a first direction x. The connecting post 134 is formed with a connecting hole 133. The gasket 135 is located on the side of the connecting post 134 where the third surface 1341 is located, and is located at the end of the third surface 1341 that is away from the housing 11. The gasket 135 protrudes from the third surface 1341. In other words, by providing the gasket 135 on the end of the third surface 1341 of the connecting post 134 that is away from the housing 11, the end of the second surface 132 of the first connector 13 that is away from the housing 11 protrudes more than the end that is closer to the housing 11. Thus, by providing gaskets 135 of different thicknesses, the degree of protrusion of the second surface 132 from the end away from the housing 11 relative to the end closer to the housing 11 can be varied, thereby providing greater flexibility in adjusting the second surface 132 of the first connector 13.

[0101] The gasket 135 is located on the side of the third surface 1341 of the connecting post 134 and at the end of the third surface 1341 away from the housing 11. That is, the gasket 135 is only provided in a portion of the third surface 1341. In this case, the first area 1321 may include the surface of the gasket 135 facing away from the third surface 1341, and the second area 1322 may include the portion of the third surface 1341 where the gasket 135 is not provided.

[0102] 5 , the thickness of each portion of the gasket 135 may be substantially the same.

[0103] 6 , the thickness of the gasket 135 may vary at different locations. For example, the thickness of the gasket 135 may gradually decrease from the end away from the housing 11 to the end closer to the housing 11. The surface of the gasket 135 facing the connecting post 134 may be substantially flat to facilitate a snug fit with the connecting post 134, while the surface of the gasket 135 facing away from the connecting post 134 may be substantially inclined to achieve a gradually decreasing thickness of the gasket 135 from the end away from the housing 11 to the end closer to the housing 11.

[0104] Referring to Figures 3, 5, and 6, the connector 10 further includes a seal 17. The seal 17 is located on the side of the second end surface 114 of the housing 11 and at least partially protrudes from the second end surface 114. When viewed along the first port 1111, the seal 17 is arranged around the first port 1111. Along the first direction x, at least a portion of the seal 17 protrudes from the second surface 132. The seal 17 can achieve a seal between the connector 10 and the compressor 20. The portion of the seal 17 that protrudes from the second end surface 114 and the second surface 132 can be compressed when the connector 10 and the compressor 20 are fixed, thereby improving the tightness of the connection between the connector 10 and the compressor 20.

[0105] In the first direction x, the second surface 132 may protrude beyond the second end surface 114. In this way, the second surface 132 may limit the degree of compression of the seal 17. For example, when the seal 17 is compressed and the second surface 132 contacts the compressor 20, tightening the nut may be stopped to avoid excessive compression of the seal 17 and damage.

[0106] Referring to FIG. 7 , seal 17 has a sealing surface 173 facing away from housing 11. Sealing surface 173 is provided with a material-reducing opening 1731. When viewed along first port 1111, material-reducing opening 1731 is arranged around first port 1111. The provision of material-reducing opening 1731 reduces the mass of seal 17 and minimizes the amount of compression of seal 17. This reduces the rebound force generated by compression of seal 17 when connector 10 is connected to compressor 20, making the side of seal 17 away from first connector 13 less likely to rebound and tilt. This alleviates the problem of connector 10 tilting on the side opposite to the compressor 20 when the connector 10 and compressor 20 are fixed on one side, thereby ensuring the sealing performance of seal 17 between the connector 10 and compressor 20.

[0107] The seal 17 has two inclined surfaces 1732 that contribute to the formation of the material reduction opening 1731. Both inclined surfaces 1732 are inclined relative to the first direction x, and the distance between the two inclined surfaces 1732 gradually decreases along the direction from the opening of the material reduction opening 1731 to the bottom wall. As a result, when the seal 17 is squeezed, the inclination of the inclined surfaces 1732 can be used to cause the seal 17 to deform as much as possible toward the material reduction opening 1731, thereby increasing the deformation of the seal 17 and enhancing the sealing performance between the connector 10 and the compressor 20.

[0108] The distance between the two inclined surfaces 1732 gradually decreases from the opening of the material reduction opening 1731 to the bottom wall. The larger distance at the opening of the material reduction opening 1731 can accommodate more deformation of the seal 17, while the smaller distance at the bottom wall can restrain the deformation of the seal 17. Furthermore, the deformation of the seal 17 at the two inclined surfaces 1732 is roughly the same, which can improve the smoothness of the seal 17 during sealing.

[0109] The seal 17 also has a connecting surface 1733 that participates in forming the material reduction opening 1731. The connecting surface 1733 is connected between the two inclined surfaces 1732, and the connecting surface 1733 is set at an angle to both inclined surfaces 1732. By providing the connecting surface 1733, the distance between the two inclined surfaces 1732 at the bottom wall of the material reduction opening 1731 can be increased by using the connecting surface 1733, thereby increasing the space for accommodating the deformation of the seal 17. In this case, the material reduction opening 1731 has a larger space, while the mass of the seal 17 is smaller, so that the seal 17 has a smaller rebound force after being squeezed between the connector 10 and the compressor 20. Therefore, when the connector 10 is connected to the compressor 20 on only one side, the seal 17 is less likely to warp on the side opposite to where the connector 10 and the compressor 20 are fixed.

[0110] It should be noted that the material reduction port 1731 can be the one recorded above including two inclined surfaces 1732, such as a roughly V-shaped material reduction port; it can also be the one recorded above including two inclined surfaces 1732 and a connecting surface 1733, such as a roughly U-shaped material reduction port, etc. In addition, the material reduction port 1731 can also adopt other shapes, which is not limited to this.

[0111] It is understood that opposite sides of the seal 17 may respectively abut the surface of the compressor 20 and the housing 11 of the connector 10 to achieve a seal between the surface of the compressor 20 and the housing 11. In an exemplary embodiment, the seal 17 may be disposed on the second end surface 114 of the housing 11. In this case, to achieve a reliable connection between the seal 17 and the housing 11, the seal 17 and the housing 11 may be connected by means of an adhesive or the like to prevent the seal 17 from falling off.

[0112] In another exemplary embodiment, the second end face 114 of the shell 11 may be provided with an annular groove 1113, and part of the seal 17 may be located in the annular groove 1113. The provision of the annular groove 1113 can, on the one hand, position the installation position of the seal 17 on the shell 11, thereby speeding up the assembly speed between the seal 17 and the shell 11; on the other hand, it can have a restraining effect on the seal 17, thereby accommodating the deformation of the seal 17 caused by extrusion and making it difficult to move.

[0113] The portion of the seal 17 located in the annular groove 1113 may include a first portion 171 and a second portion 172 distributed in the depth direction of the annular groove 1113. The first portion 171 may be located within the annular groove 1113, and the second portion 172 may be located outside the annular groove 1113. The second portion 172 located outside the annular groove 1113 may deform when the connector 10 is in contact with the compressor 20, thereby improving the tightness of the connection between the connector 10 and the compressor 20.

[0114] The sealing member 17 may be mounted in the annular groove 1113 by snapping, or by bonding or other methods, which are not limited thereto.

[0115] The seal 17 can be any device with sealing properties, such as a sealing ring. In the embodiment of the present application, the seal 17 is a device with elasticity and high heat resistance. The seal 17 is elastic so that when the connector 10 is connected to the compressor 20, the seal 17 can be in a compressed state to improve the tightness of the connection between the connector 10 and the compressor 20. The seal 17 has high heat resistance, which can prevent the seal 17 from being damaged by the surface heat of the compressor 20 and improve the service life of the seal 17. Specifically, the seal 17 can be a silicone rubber seal, which is low in cost and has elasticity and high heat resistance.

[0116] The sealing member 17 may not belong to the connector 10 , and when the connector 10 and the compressor 20 are connected, the sealing member 17 may be directly provided between the connector 10 and the compressor 20 . This is not limited to this.

[0117] Next, the connector 10 will be further described.

[0118] 8 and 9 , the connector 10 further includes a connector terminal 12 for electrically connecting to the compressor terminal 21. 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.

[0119] For example, one of the connector terminal 12 and the compressor terminal 21 can be a male terminal, and the other can be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, and the compressor terminal 21 is a male terminal. The connector terminal 12 is formed with a socket, and at least a portion of the compressor terminal 21 is inserted into the socket and electrically connected to the connector terminal 12. In other words, when the connector terminal 12 and the compressor terminal 21 are connected, 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.

[0120] Among them, the first direction x can be roughly parallel to the plug-in direction of the compressor terminal 21 and the connector terminal 12, so that when the second connecting member 22 arranged in the connecting hole 133 connects the connector 10 and the compressor 20, the compressor terminal 21 and the connector terminal 12 can move relative to each other along the plug-in direction. Compared with moving in a direction intersecting with the plug-in direction, the risk of breaking the compressor terminal 21 and the connector terminal 12 can be avoided.

[0121] The housing 11 is formed with a first cavity 1117. When viewed along the first port 1111, the first cavity 1117 is located within and communicates with the first port 1111. The connector terminal 12 is located in the first cavity 1117. This allows the compressor terminal 21 to extend into the first cavity 1117 through the first port 1111 and electrically connect to the connector terminal 12. The provision of the first cavity 1117 facilitates positioning the connector terminal 12 within the housing 11.

[0122] The connector 10 may include a plurality of connector terminals 12, and the housing 11 may be formed with a plurality of first cavities 1117, with each connector terminal 12 correspondingly located in each first cavity 1117. For example, the connector 10 may include two connector terminals 12, and the housing 11 may be formed with two first cavities 1117; or the connector 10 may include three connector terminals 12, and the housing 11 may be formed with three first cavities 1117, and so on, without limitation.

[0123] 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.

[0124] Housing 11 defines a second chamber 1118, which extends from second end surface 114 toward first end surface 113. Second chamber 1118 forms a first port 1111 on the side of second end surface 114. When connector 10 is connected to compressor 20, second chamber 1118 is closer to compressor 20 than first chamber 1117. The provision of second chamber 1118 reduces the mating area between connector 10 and compressor 20, lowering the precision design requirements for connector 10's mating surfaces.

[0125] Along the first direction x, the cross-sectional profile of the second cavity 1118 is larger than the cross-sectional profiles of all first cavities 1117, and along the first direction x, the cross-sectional profiles of all first cavities 1117 are located within the cross-sectional profile of the second cavity 1118. Thus, when the connector 10 includes multiple connector terminals 12 and the compressor 20 includes multiple 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 cavity 1118 and reach the corresponding first cavity 1117, thereby achieving electrical connection with the corresponding connector terminals 12.

[0126] It is understood that the annular groove 1113 for arranging the seal 17 may or may not be in communication with the second chamber 1118. In the embodiment of the present application, the annular groove 1113 is not in communication with the second chamber 1118 to prevent the seal 17 from deforming toward the second chamber 1118 during compression and deformation, thereby affecting the installation stability of the seal 17.

[0127] Referring to FIG9 , the compressor 20 may include a terminal block 23 for securing the compressor terminal 21. The terminal block 23 protrudes outward from the compressor body. When the compressor terminal 21 is connected to the connector terminal 12, the terminal block 23 may be located within the second cavity 1118. This improves the sealing performance between the connector 10 and the compressor 20.

[0128] In some embodiments, the housing 11 may include a first housing portion 111 and a second housing portion 112. 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 facilitates assembly of the connector terminal 12. The first housing portion 111 may be provided with a second chamber 1118.

[0129] It should be noted that when multiple first chambers 1117 are formed on the shell 11, the first shell portion 111 has first ports 1111 equal in number to the first chambers 1117 and second ports 1114 equal in number to the first chambers 1117. Each first port 1111 is connected to each first chamber 1117, and each second port 1114 is connected to each first chamber 1117.

[0130] The first housing portion 111 has a higher heat resistance than the second housing portion 112. Compared to the second housing portion 112, the first housing portion 111 is less likely to deform under high temperature conditions. Therefore, by disposing the first port 1111 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 a higher heat resistance, which can prevent the internal connector terminals 12 from being softened by high temperatures, thereby extending the service life of the connector terminals 12.

[0131] If the connector 10 includes a seal 17, the seal 17 is connected to the first housing portion 111. The seal 17 is arranged on the first housing portion 111. Even if heat from the surface of the compressor 20 is transferred to the seal 17 and the first housing portion 111, the first housing portion 111 is not easily deformed, thereby providing a stable support effect for the seal 17, ensuring the sealing performance between the compressor 20 and the connector 10, while also ensuring a stable connection between the compressor 20 and the connector 10.

[0132] The first housing portion 111 can be made of a highly heat-resistant material. For example, the first housing portion 111 can 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, a high-temperature and fire-resistant insulation material that prevents softening of the connector terminals 12 during operation.

[0133] The second housing portion 112 can cover the second port 1114 and the connector terminal 12. The provision of the second port 1114 facilitates installation of the connector terminal 12 within the housing 11. The second housing portion 112 covers the second port 1114 and the connector terminal 12, allowing the connector terminal 12 and the compressor terminal 21 to be enclosed by the housing 11 of the connector 10 when connected. This prevents the presence of refrigerant near the connector terminals, which could easily cause sparks when the connector terminals 12 and the compressor terminals 21 are connected. The first housing portion 111 can have a second end surface 114, and the second housing portion 112 can have a first end surface 113.

[0134] 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, so that the injection-molded housing portion and the first housing portion 111 are at least an integrally-molded structure. Specifically, after the first housing portion 111 is molded, at least the first housing portion 111 is placed in a mold to form a cavity for molding the injection-molded housing portion, and then a molding compound is injected into the cavity to obtain the injection-molded housing portion.

[0135] The glue-potted housing portion is formed by a glue-potting process, and the glue-potted housing portion is connected to the first housing portion 111. Therefore, the glue-potted housing portion and the first housing portion 111 are at least an integrally molded structure formed by glue-potting. Specifically, the first housing portion 111 is formed with a molding groove, and at least the molding groove participates in constructing the glue-potted housing portion. Then, molding material is injected into the molding groove to obtain the glue-potted housing portion.

[0136] In summary, regardless of 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 integrally formed. This improves the tightness of the connection between the second housing portion 112 and the first housing portion 111, and the sealing between the second housing portion 112 and the first housing portion 111, compared to independently molding the second housing portion 112 and the first housing portion 111 and then assembling them. The second housing portion 112 and the first housing portion 111 of the connector 10 are sealed, 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 17. This improves the overall sealing of the connector 10.

[0137] The second housing portion 112 can be made of a sealant shell, which provides excellent sealing performance. The second housing portion 112 can be elastic or non-elastic, allowing for flexible design based on actual needs. In the embodiment of the present application, the second housing portion 112 can be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing properties. The second housing portion 112 can be made of plastic or silicone, without limitation.

[0138] To enhance the connection reliability between the second housing portion 112 and the first housing portion 111, one of the second housing portion 112 and the first housing portion 111 can be provided with a hook 1121, and the other can be provided with a slot 1115 that matches the hook 1121, with the hook 1121 located within the slot 1115. The second housing portion 112 and the first housing portion 111 can be hooked together via the hook 1121, preventing them from easily disengaging. It is understood that the second housing portion 112 can be provided with the hook 1121 and the first housing portion 111 can be provided with the slot 1115; alternatively, the second housing portion 112 can be provided with the slot and the first housing portion 111 can be provided with the hook, without limitation.

[0139] 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 .

[0140] The connector 10 also includes a cover member that covers the second port 1114, and the second housing portion 112 covers the cover member. The cover member prevents moisture, dust, and other impurities from entering the first housing portion 111 and affecting the performance of the connector terminal 12. Furthermore, when the second housing portion 112 includes an injection-molded housing portion or a potted housing portion, the cover member prevents the molding compound of the second housing portion 112 from passing through the second port 1114 and reaching the connector terminal 12, thereby encasing the connector terminal 12 and ensuring effective electrical connection between the connector terminal 12 and the compressor terminal 21.

[0141] The connector terminal 12 and the cover member may abut 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, thereby preventing the connector terminal 12 and the compressor terminal 21 from being damaged by forced insertion.

[0142] 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 .

[0143] One of the cover plate 14 and the first housing portion 111 can be provided with a limiting protrusion 141, and the other can be provided with a limiting groove 1116, with the limiting protrusion 141 located within the limiting groove 1116. The provision of the limiting protrusion 141 and the limiting groove 1116 can facilitate positioning of the cover plate 14 and the first housing portion 111 during assembly, thereby improving assembly efficiency of the cover plate 14 and the first housing portion 111. It is 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; alternatively, 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, without limitation. 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 the limiting groove 1116.

[0144] If the housing 11 is formed with a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0145] The connector 10 also includes a connecting wire 15, which is electrically connected to the connector terminal 12 and is used to enable signal interaction between the compressor 20 and the outside world when the connector terminal 12 is connected to the compressor terminal 21. Among them, the end of the connecting wire 15 connected to the connector terminal 12 is wrapped by the second shell portion 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 portion 112 includes an injection molding shell portion and / or a glue-filling shell portion, the second shell portion 112 can directly wrap the end of the connecting wire 15 connected to the connector terminal 12 during injection molding and / or glue-filling. If the connector 10 includes multiple connector terminals 12, the connecting wire 15 is electrically connected to the multiple connector terminals 12.

[0146] Example 2

[0147] Referring to Figures 10 and 11 , this embodiment differs from the first embodiment in that: in this embodiment, the first surface 131 includes a third region 1311 and a fourth region 1312 distributed along the second direction y on opposite sides of the connection hole 133. The fourth region 1312 is closer to the housing 11 than the third region 1311, and at least one point on the fourth region 1312 protrudes beyond the third region 1311. Thus, when the connector 10 is connected and secured to the compressor 20, the fourth region 1312 first contacts the locking member 40. If the fourth region 1312 contacts the locking member 40, the locking member 40 applies a third force F3 to the first connecting member 13 at the fourth region 1312. The third force F3 is directed from the locking member 40 toward the first connecting member 13. 11 , under the action of the third force F3, the warping problem of the second end surface 114 away from the end of the first connecting member 13 can be improved, that is, the warping problem of the connector 10 on the opposite side where it is fixed to the compressor 20 due to the unilateral fixation of the connector 10 and the compressor 20 can be improved.

[0148] 10 , the first surface 131 may be an inclined surface inclined relative to the first direction x, so that the first surface 131 is flat and easy to process.

[0149] Furthermore, the acute angle θ2 between the first surface 131 and the first direction x is greater than or equal to 70° and less than or equal to 89°. By properly limiting the acute angle θ2 between the first surface 131 and the first direction x, the problem of the connector 10 tilting on the side opposite to the compressor 20 when the connector 10 is fixed to one side can be improved. The inclination of the first surface 131 can also be moderate, preventing sharp corners that could cause accidental injury. The acute angle θ2 between the first surface 131 and the first direction x can be 70°, 75°, 80°, 85°, 89°, and so on, without limitation.

[0150] It should be noted that a gasket may also be provided on one end of the first surface 131 close to the housing 11 to ensure that at least one point on the fourth area 1312 protrudes from the third area 1311 , and this embodiment of the present application is not limited thereto.

[0151] It should be noted that it is also possible to simultaneously set at least one point on the fourth area 1312 to protrude from the third area 1311, and at least one point on the first area 1321 to protrude from the second area 1322, so as to improve the problem of the connector 10 being warped on the opposite side of the connector 10 fixed to the compressor 20 due to unilateral fixation.

[0152] In other embodiments, referring to FIG. 12 , the connector 10 includes a sealing member 17. Specifically, referring to FIG. 12 and FIG. 13 , the housing 11 has a first end face 113 and a second end face 114 that are opposite each other along a first direction x. The second end face 114 is formed with a first port 1111. The first port 1111 is used for inserting the compressor terminal 21 on the compressor 20 into the housing 11. The first connector 13 is located on one side of the housing 11 and is connected to the housing 11. In conjunction with Figures 12 and 14, the first connecting member 13 is used to connect to the compressor 20, at least part of the seal 17 protrudes from the second end face 114, the seal 17 and the housing 11 are located on the same side of the first connecting member 13 and the seal 17 is arranged around the first port 1111, and the seal 17 has a sealing mating surface 174 facing away from the first end face 113. The sealing mating surface 174 is inclined relative to the first direction x. Along the first direction x, the end of the sealing mating surface 174 away from the first connecting member 13 protrudes from the end of the sealing mating surface 174 close to the first connecting member 13.

[0153] In the embodiment of the present application, the sealing mating surface 174 of the seal 17 facing away from the first end face 113 is inclined relative to the first direction x, and along the first direction x, the end of the sealing mating surface 174 away from the first connecting member 13 protrudes beyond the end of the sealing mating surface 174 close to the first connecting member 13. In this way, the end of the seal 17 away from the first connecting member 13 has a margin to accommodate its warping, and the seal 17 is not easy to warp during sealing, which can ensure the sealing performance between the seal connector 10 and the compressor 20 of the seal 17, and improve the problem of warping of the connector 10 on the opposite side where the compressor 20 is fixed, which is caused by the connector 10 being connected to the compressor 20 only on one side in the related technology.

[0154] Among them, the first direction x can be roughly parallel to the plug-in direction of the compressor terminal 21 and the connector terminal 12, so that when the seal 17 seals the connector 10 and the compressor 20, the compressor terminal 21 and the connector terminal 12 can move relative to each other along the plug-in direction. Compared with moving in a direction intersecting with the plug-in direction, the risk of breaking the compressor terminal 21 and the connector terminal 12 can be avoided.

[0155] In the embodiment of the present application, the first connector 13 and the second connector 22 are connected via a locking member 40. Specifically, a connection hole 133 extending along the first direction x is formed on the first connector 13. The compressor 20 is provided with a second connector 22 extending along the first direction x. The second connector 22 passes through the connection hole 133 and is fixedly connected to the locking member 40. When the locking member 40 is connected to the second connector 22, it can press against the connector 10, applying a force substantially in the first direction x to the connector 10. The locking member 40 can be a nut, and the second connector 22 is threadedly connected to the nut. By tightening the nut, the distance between the compressor 20 and the connector 10 can be shortened, thereby achieving compression of the seal 17.

[0156] It should be noted that the first connecting member 13 and the second connecting member 22 can also be connected by plugging, snapping, etc., which is not limited to this.

[0157] Furthermore, the acute angle a1 of the sealing mating surface 174 relative to the first direction x is greater than or equal to 80° and less than or equal to 89.9°. By reasonably limiting the acute angle a1 of the sealing mating surface 174 relative to the first direction x, it is possible to prevent the end of the seal 17 away from the first connector 13 from easily warping due to an excessively large inclination angle, thereby preventing the sealing effect from being achieved. It is also possible to prevent the sealing 17 from having an excessively large inclination angle when the first connector 13 is connected to the second connector 22 on the compressor 20 due to an excessively small inclination angle, that is, the margin is too large, and the housing 11 cannot press the seal 17. For example, the acute angle a1 of the sealing mating surface 174 relative to the first direction x can be 80°, 86°, 87°, 88°, 89°, 89.9°, etc., and this is not limited to this.

[0158] Furthermore, the acute angle a1 of the sealing mating surface 174 relative to the first direction x is greater than or equal to 87° and less than or equal to 89.5°. For example, the acute angle a1 of the sealing mating surface 174 relative to the first direction x can be 87°, 88°, 89°, 89.1°, 89.3°, 89.5°, etc., without limitation.

[0159] In the embodiment of the present application, opposite sides of the seal 17 can respectively abut the surface 31 of the compressor 20 and the housing 11 to achieve sealing between the surface 31 of the compressor 20 and the housing 11. In an exemplary embodiment, the second end surface 114 is provided with an annular groove 1113. The annular groove 1113 is arranged around the first port 1111, and a portion of the seal 17 can be located within the annular groove 1113. The provision of the annular groove 1113 can, on the one hand, locate the installation position of the seal 17 on the housing 11, thereby speeding up the assembly of the seal 17 and the housing 11. On the other hand, it can constrain the seal 17, accommodating deformation of the seal 17 caused by extrusion and preventing it from moving.

[0160] Referring to FIG. 12 , the portion of seal 17 located in annular groove 1113 may include: seal 17 includes a first portion 171 and a second portion 172 distributed in the depth direction of annular groove 1113; first portion 171 may be located within annular groove 1113, and second portion 172 may be located outside annular groove 1113. Second portion 172 located outside annular groove 1113 may deform when connector 10 is connected to compressor 20, thereby enhancing the tightness of the connection between connector 10 and compressor 20.

[0161] It is understood that the annular groove 1113 may or may not be in communication with the first port 1111. In the embodiment of the present application, the annular groove 1113 is not in communication with the first port 1111 to prevent the seal 17 from deforming toward the first port 1111 during compression, which could affect the installation stability of the seal 17. It should be noted that the seal 17 can be installed in the annular groove 1113 by snap-fitting or by bonding, etc., without limitation.

[0162] The seal 17 can be any device with sealing properties, such as a sealing ring. In the embodiment of the present application, the seal 17 is elastic, so that when the connector 10 is connected to the compressor 20, the seal 17 can be in a compressed state to improve the tightness of the connection between the connector 10 and the compressor 20. The seal 17 has high heat resistance, which can prevent the seal 17 from being damaged by the heat from the surface 31 of the compressor 20, thereby improving the service life of the seal 17. Specifically, the seal 17 can be a silicone rubber seal 17. Silicone rubber has low cost and is elastic and highly heat-resistant, and this is not limited to this.

[0163] To make the sealing mating surface 174 tilt relative to the first direction x, and to make the end of the sealing mating surface 174 away from the first connecting member 13 protrude further than the end of the sealing mating surface 174 closer to the first connecting member 13 along the first direction x, in one embodiment, with reference to FIG12 , the depth of the annular groove 1113 in the first direction x gradually increases along the second direction y. The second direction y is perpendicular to the first direction x and runs from the end of the annular groove 1113 away from the first connecting member 13 to the end closer to the first connecting member 13. In other words, the depth of the annular groove 1113 is adjusted.

[0164] It can be understood that when the seal 17 is placed in the annular groove 1113 inclined along the first direction x, the depth of the first part 171 of the seal 17 in the annular groove 1113 will be consistent with the depth of the annular groove 1113, that is, the depth of the first part 171 in the first direction x gradually increases with the depth of the annular groove 1113; at this time, if the heights of the various parts of the seal 17 in the first direction x remain unchanged (for example, the sealing mating surface 174 of the seal 17 and its back side 176 are roughly parallel), then the second part 172 of the seal 17 outside the annular groove 1113 is: the depth of the second part 172 in the first direction x gradually decreases, which can meet the requirement that the end of the sealing mating surface 174 away from the first connector 13 in the first direction x protrudes beyond the end of the sealing mating surface 174 close to the first connector 13, and then when the first connector 13 is connected to the second connector 22 on the compressor 20, the end of the seal 17 away from the first connector 13 is not easy to warp, thereby ensuring the sealing performance of the seal 17 between the sealing connector 10 and the compressor 20.

[0165] Furthermore, the bottom wall of the annular groove 1113 includes multiple stepped surfaces, which are distributed sequentially along the second direction y. Along the second direction y, the depth of each stepped surface in the first direction x remains constant, while along the second direction y, the depth of the multiple stepped surfaces in the first direction x gradually increases. By providing multiple stepped surfaces, when the seal 17 is placed in the annular groove 1113, the seal 17 cannot fit with each of the stepped surfaces, resulting in gaps between the multiple stepped surfaces and the seal 17. These gaps provide deformation space for the seal 17 when the first connector 13 is connected to the compressor 20 along the first direction x, allowing the back surface 176 of the seal 17 to be compressed after being squeezed by the connector 10 and the compressor 20, thereby improving the sealing performance of the seal 17.

[0166] It should be noted that, in addition to designing the bottom wall of the annular groove 1113 to include the aforementioned multiple stepped surfaces, the bottom wall of the annular groove 1113 can also be designed to include multiple grooves, with the multiple grooves distributed along the second direction y. Along the second direction y, the spacing between the groove openings and the second end surface 114 in the first direction x gradually increases. In this way, the gap between the groove and the back surface 176 can also be utilized to provide deformation space for the back surface 176 of the seal 17, thereby improving the sealing performance of the seal 17. The grooves can be rectangular grooves, serrated grooves, etc., which are not limited to this.

[0167] To ensure that the sealing surface 174 is inclined relative to the first direction x, and that the end of the sealing surface 174 distal from the first connector 13 protrudes beyond the end of the sealing surface 174 proximal to the first connector 13 along the first direction x, in another embodiment, referring to FIG16 , the sealing surface 174 of the sealing member 17 is inclined relative to the back surface 176. This adjustment to the structure of the sealing member 17 facilitates manufacturing. In this case, the sealing member 17 can be disposed on the second end surface 114. Alternatively, the sealing member 17 can be partially disposed in the annular groove 1113 of the second end surface 114.

[0168] If the seal 17 is partially located in the annular groove 1113, the depth of the annular groove 1113 in the first direction x can remain constant along the second direction y. If the seal 17 is partially located in the annular groove 1113, the depth of the annular groove 1113 in the first direction x can also gradually increase along the second direction y as described above, without limitation.

[0169] Next, the connector 10 will be further described.

[0170] In an embodiment of the present application, along the first direction x, the first connecting member 13 protrudes from the second end face 114, and along the first direction x, the sealing mating surface 174 protrudes from the first connecting member 13. In this way, when the first connecting member 13 is connected to the second connecting member 22 and the first connecting member 13 abuts against the compressor 20, the second end face 114 has not yet abutted against the compressor 20. A deformation space can be provided between the two for the seal 17, so that the seal 17 can be compressed after being squeezed by the connector 10 and the compressor 20, thereby improving the sealing performance of the seal 17.

[0171] In order to prevent assembly errors when sealing member 17 is assembled into annular groove 1113, a foolproof structure is required. For example, referring to FIG16 , in the embodiment of the present application, sealing member 17 is provided with one of positioning protrusion 1119 and positioning groove 175, and the inner wall of annular groove 1113 is provided with the other positioning protrusion 1119 and positioning groove 175, and positioning protrusion 1119 is embedded in positioning groove 175.

[0172] It may be that a positioning groove 175 is provided at the end of the seal 17 close to the first connecting member 13, and a positioning protrusion 1119 is correspondingly provided at the end of the annular groove 1113 close to the first connecting member 13; or, a positioning protrusion 1119 is provided at the end of the seal 17 close to the first connecting member 13, and a positioning groove 175 is correspondingly provided at the end of the annular groove 1113 close to the first connecting member 13; or, a positioning protrusion 1119 is provided at the end of the seal 17 away from the first connecting member 13, and a positioning groove 175 is correspondingly provided at the end of the annular groove 1113 away from the first connecting member 13; or, a positioning groove 175 is provided at the end of the seal 17 away from the first connecting member 13, and a positioning protrusion 1119 is correspondingly provided at the end of the annular groove 1113 away from the first connecting member 13, and there is no limitation on this.

[0173] By providing the positioning protrusion 1119 and the positioning groove 175, on the one hand, the installation position of the seal 17 in the annular groove 1113 can be limited, which is beneficial to improving the positioning installation speed and accuracy of the seal 17 installed in the annular groove 1113; on the other hand, the seal 17 can be limited, and the installation stability of the seal 17 in the annular groove 1113 can be improved, ensuring that the seal 17 is not easy to fall off from the annular groove 1113 when squeezed by the connector 10 and the compressor 20, thereby ensuring the sealing performance between the connector 10 and the compressor 20.

[0174] There may be multiple positioning protrusions 1119 and positioning grooves 175, and each positioning protrusion 1119 may correspond to a positioning groove 175. For example, multiple positioning protrusions 1119 or multiple positioning grooves 175 may be provided at the end of the sealing member 17 close to the first connecting member 13, and multiple positioning grooves 175 or positioning protrusions 1119 may be provided at the end of the annular groove 1113 close to the first connecting member 13; or, multiple positioning protrusions 1119 or multiple positioning grooves 175 may be provided at the end of the sealing member 17 away from the first connecting member 13, and multiple positioning grooves 175 or positioning protrusions 1119 may be provided at the end of the annular groove 1113 away from the first connecting member 13; or, multiple positioning protrusions 1119 or multiple positioning grooves 175 may be provided at the middle portion of the sealing member 17 away from the first connecting member 13, and multiple positioning grooves 175 or positioning protrusions 1119 may be provided at the middle portion of the annular groove 1113 away from the first connecting member 13. The above are not limited to the above. Among them, the number of positioning protrusions 1119 can be one, two, three, four, etc., as long as the number of positioning protrusions 1119 corresponds to the number of positioning grooves 175. It can be flexibly designed according to actual needs and is not limited to this.

[0175] In the embodiment of the present application, referring to Figures 13 to 15 , the connector 10 includes a housing 11 and a connector terminal 12. The housing 11 defines a first chamber 1117, and the connector terminal 12 is located in the first chamber 1117. The housing 11 defines a first port 1111 communicating with the first chamber 1117. The connector terminal 12 is configured to electrically connect to the compressor terminal 21 extending into the first chamber 1117 via the first port 1111.

[0176] The connector 10 may include at least two connector terminals 12, and the housing 11 may be formed with at least two first cavities 1117, the number of which is equal to the number of the at least two connector terminals 12, with each connector terminal 12 being mounted in a one-to-one correspondence within each first cavity 1117. For example, the connector 10 may include two connector terminals 12 and the housing 11 may be formed with two first cavities 1117; alternatively, the connector 10 may include three connector terminals 12 and the housing 11 may be formed with three first cavities 1117, and so on, without limitation.

[0177] In other embodiments, referring to FIG. 19 , FIG. 19 is a schematic cross-sectional view of the connector 10 shown in FIG. 18 . In conjunction with FIG. 17 and FIG. 18 , the connector 10 includes a housing 11, a first connector 13, and one or more support plates 16. The first connector 13 has a first mating surface 136 and a first back surface 137 that are opposite each other along a first direction x. The first connector 13 and the housing 11 are arranged and connected along a second direction y. The support plate 16 has a second mating surface 161 and a second back surface 162 that are opposite each other along the first direction x. The first mating surface 136 and the second mating surface 161 are located on one side of the connector 10 in the first direction x, while the first back surface 137 and the second back surface 162 are located on the other side of the connector 10 in the first direction x. The support plate 16 includes a connecting end 163 connected to the first connector 13 and a free end 164 that is distal to the first connector 13. The free end 164 is located outside the first connector 13 and on opposite sides of the first connector 13 from the housing 11. The first direction x is perpendicular to the second direction y.

[0178] The above-mentioned free end 164 protrudes from the first connecting member 13 and is located on opposite sides of the first connecting member 13 with the outer shell 11. It can be understood that: the projection of the free end 164 in the first plane is located outside the projection of the first connecting member 13 in the first plane, and the projection of the free end 164 in the first plane and the projection of the outer shell 11 in the first plane are respectively located on opposite sides of the projection of the first connecting member 13 in the first plane, wherein the first plane is parallel to the first direction x and the second direction y.

[0179] The first connector 13 is used to connect the connector 10 to the compressor 20 . The first mating surface 136 and the second mating surface 161 may be located on a side of the connector 10 close to the compressor 20 when the connector 10 is connected to the compressor 20 .

[0180] The connector 10 of the embodiment of the present application connects the connecting end 163 of the support plate 16 to the first connecting member 13, and the free end 164 of the support plate 16 is located outside the first connecting member 13 and on both sides of the shell 11 opposite to the first connecting member 13. In this way, if the connector 10 is connected to the compressor 20, the free end 164 located on the opposite side of the shell 11 can also contact the compressor 20, so that the connecting force of the first connecting member 13 can be relatively evenly distributed on the shell 11 and the support plate 16 on both sides, and it is not easy to cause the problem of warping on one side of the shell 11. That is, it can improve the problem of warping of the connector 10 on the opposite side where the compressor 20 is fixed due to the connector 10 being connected to the compressor 20 only on one side in the related art.

[0181] Among them, the first mating surface 136 can be adapted to the corresponding surface on the compressor 20 to increase the contact area between the first mating surface 136 and the compressor 20, thereby improving the stability between the two. The second mating surface 161 can be adapted to the corresponding surface on the compressor 20 to increase the contact area between the second mating surface 161 and the compressor 20, thereby improving the stability between the two. For example, if the surface on the compressor 20 corresponding to the connector 10 is a plane, the first mating surface 136 and the second mating surface 161 are both planes and the first mating surface 136 and the second mating surface 161 are located in the same plane. In this way, the first mating surface 136 of the first connecting member 13 and the second mating surface 161 of the support plate 16 can also be fitted with the compressor 20 at the same time, thereby increasing the contact area between the connector 10 and the compressor 20 and improving the stability of the connection between the two.

[0182] Referring to FIG. 20 , FIG. 20 is a schematic diagram of the bottom view of the connector 10 provided in other embodiments of the present application. The one or more support plates 16 include a first support plate 165, with the direction from the connection end 163 to the free end 164 of the first support plate 165 being along the second direction y. Because the housing 11 and the first connector 13 are arranged along the second direction y, when the first connector 13 is connected to the compressor 20, the side of the housing 11 away from the first connector 13 along the second direction y is susceptible to warping. Designing the direction from the connection end 163 to the free end 164 of the first support plate 165 to be along the second direction y, which aligns with the direction in which the housing 11 is susceptible to warping, allows the first support plate 165 to better resist this warping problem.

[0183] Continuing with Figure 20 , along the second direction y, the length of the first support plate 165 is L1, and the length of the housing 11 is L2. The connector 10 satisfies the following relationship: 2 / 3 ≤ L1 / L2 ≤ 1. By properly limiting the length L1 of the first support plate 165 along the second direction y relative to the length L2 of the housing 11, the first connector 13 can be positioned approximately in the middle of the connector 10 along the second direction y. This ensures that, after the connector 10 and the compressor 20 are electrically connected, the forces acting on the housing 11 and the first support plate 165 on both sides of the first connector 13 are relatively balanced, making warping less likely. If L1 / L2 is less than 2 / 3, the length of the first support plate 165 relative to the housing 11 is too short, making it insufficient to effectively resist warping of the housing 11. If L1 / L2 is greater than 1, the length of the first support plate 165 relative to the housing 11 is too long. While this effectively resists warping of the housing 11, it increases the size of the connector 10, hindering its miniaturization. For example, L1 / L2 can be 2 / 3, 7 / 9, 5 / 6, 8 / 9, 1, etc., without limitation.

[0184] Referring to FIG. 21 , FIG. 21 is a schematic diagram of the bottom-up structure of a connector 10 provided in yet another embodiment of the present application. The one or more support plates 16 include a second support plate 166 and a third support plate 167. Along the third direction z, the second support plate 166 and the third support plate 167 are located on opposite sides of the first connector 13. The first direction x, the second direction y, and the third direction z are perpendicular to each other. The direction from the connection end 163 to the free end 164 of the second support plate 166 is inclined relative to the second direction y, while the direction from the connection end 163 to the free end 164 of the third support plate 167 is inclined relative to the second direction y. In this way, the second and third support plates 166, 167, can be combined to prevent the housing 11 from warping. Compared to the first support plate 165, the design of the second and third support plates 166, 167, is more flexible and can be adjusted according to actual needs.

[0185] Among them, the number of the second support plate 166 and the third support plate 167 can be one or more, for example, there is one second support plate 166 and multiple third support plates 167; or, there are multiple second support plates 166 and one third support plate 167, or, there are multiple second support plates 166 and multiple third support plates 167, and there is no limitation on this.

[0186] It should be noted that when the support plate 16 includes the second support plate 166 and the third support plate 167, the sum of the lengths of the portions of the second support plate 166 and the third support plate 167 protruding from the first connector 13 along the second direction y can be designed to be greater than or equal to two-thirds of the length L2 of the housing 11, and less than or equal to the length L2 of the housing 11. By limiting the sum of the lengths of the portions of the second support plate 166 and the third support plate 167 protruding from the first connector 13 along the second direction y relative to the length L2 of the housing 11, when the connector 10 and the compressor 20 are connected, the weight of the second support plate 166 and the third support plate 167 in the second direction y can be ensured to be sufficient, effectively preventing the problem of warping of the housing 11.

[0187] Optionally, the direction from the connection end 163 to the free end 164 of the second support plate 166 is inclined at an acute angle θ1 relative to the second direction y, and the direction from the connection end 163 to the free end 164 of the third support plate 167 is inclined at an acute angle θ2 relative to the second direction y, and the connector 10 satisfies the following: θ1 = θ2. This ensures that the forces acting on the second and third support plates 166, 167 are substantially balanced along the third direction z, preventing warping of either end of the connector 10 in the third direction z.

[0188] It should be noted that the one or more support plates 16 in the embodiment of the present application may also include a first support plate 165 , a second support plate 166 and a third support plate 167 , which is not limited in the embodiment of the present application.

[0189] Referring again to FIG. 19 , along the first direction x, the height of the support plate 16 (the first support plate 165 , the second support plate 166 , or the third support plate 167 ) is H1, and the height of the housing 11 is H2. The connector 10 satisfies the following relationship: 1 / 3 ≤ H1 / H2 ≤ 1. By reasonably limiting the height H1 of the support plate 16 along the first direction x relative to the height H2 of the housing 11, the support plate 16 can better resist the warping of the housing 11 after the connector 10 and the compressor 20 are electrically connected. If H1 / H2 is less than 1 / 3, the height of the support plate 16 relative to the housing 11 will be too low, and the support plate 16 will be easily deformed when resisting the warping of the housing 11. If H1 / H2 is greater than 1, the height of the support plate 16 relative to the housing 11 will be too high. Although this can effectively resist the warping of the housing 11, it will cause the size of the connector 10 to be too large, which is not conducive to the miniaturization of the connector 10. For example, H1 / H2 can be 1 / 3, 2 / 3, 5 / 6, 8 / 9, 1, etc., without limitation.

[0190] In the embodiment of the present application, the first connector 13 is formed with a connecting hole 133 extending along the first direction x. The ends of the connecting hole 133 extend to the first mating surface 136 and the first back surface 137, respectively. The first back surface 137 is flush with the second back surface 162 of the support plate 16. By arranging the first back surface 137 of the first connector 13 flush with the second back surface 162 of the support plate 16, the second back surface 162 does not hinder the subsequent assembly of the connecting hole 133, thereby effectively improving the assembly convenience of the connecting hole 133. Furthermore, the flatness of the surface 31 where the first back surface 137 and the second back surface 162 are connected is improved, that is, the flatness of the connection between the first connector 13 and the support plate 16 is improved.

[0191] In another embodiment, the second back surface 162 can be lower than the first back surface 137 along the direction from the first mating surface 136 to the first back surface 137. In this way, the second back surface 162 will not hinder the subsequent assembly of the connecting hole 133, and the assembly convenience of the connecting hole 133 can also be improved.

[0192] An embodiment of the present application also provides a HVAC system, which includes the above-mentioned compressor assembly 1. Please refer to Figures 24 to 26 for the compressor assembly 1. Figure 24 shows a structural schematic diagram of the compressor assembly 1 in the embodiment of the present application, Figure 25 shows a cross-sectional structural schematic diagram in the EE direction in Figure 24, and Figure 26 shows a top structural schematic diagram of the compressor assembly 1 in Figure 24. The compressor assembly 1 includes a connector 10, a compressor 20, a detection component 30 and a control component.

[0193] Among them, the connector 10 is located outside the compressor 20 and is electrically connected to the compressor 20; the detection component 30 is located outside the compressor 20 and is installed on the connector 10, and the detection component 30 is used to detect whether the refrigerant is leaking; the control component is electrically connected to the detection component 30 and the compressor 20, and the control component is used to control the compressor 20 to shut down when the detection component 30 detects refrigerant leakage.

[0194] The compressor assembly 1 of the embodiment of the present application has a detection component 30 set on the connector 10. When the detection component 30 detects a refrigerant leakage, the control component controls the compressor 20 to shut down. In this way, after the connector 10 is electrically connected to the compressor 20, the detection component 30 on the connector 10 can promptly identify whether there is refrigerant in the surrounding area, and use the control component to take timely measures to respond, which can effectively improve the safety performance of the connector 10 after the electrical connection with the compressor 20.

[0195] Among them, compared with setting the detection component 30 on the compressor 20, setting the detection component 30 on the connector 10 is because after the connector 10 is electrically connected to the compressor 20, the casing temperature on the compressor 20 is higher, which may have a certain impact on the use effect and / or service life of the detection component 30. Therefore, when the detection component 30 is set on the connector 10, it can ensure that the use effect of the detection component 30 is more accurate and / or does not affect the service life of the detection component 30.

[0196] Among them, the control component can control the shutdown of the compressor 20 through relays, IGBTs, and controllers. For example, taking the relay as an example, the circuit for the control component to control the compressor 20 can also include a mains power supply, a leakage protection switch, and a power supply component. The leakage protection switch is arranged between the mains power supply and the power supply component. When a refrigerant leak is detected, the leakage protection switch is in the disconnected state, the mains power supply and the power supply component are electrically disconnected, the power supply component cannot be energized, and thus the compressor 20 cannot be powered to operate. The relay is electrically connected to the control component, and the static contact of the relay is connected to the neutral line between the mains power supply and the leakage protection switch, and the moving contact of the relay is connected to the neutral line between the leakage protection switch and the power supply component. Therefore, the opening and closing state of the leakage protection switch can be changed by changing the opening and closing state of the relay.

[0197] Specifically, when the detection component 30 detects a refrigerant leak and sends a refrigerant leak signal to the control component, the control component can control the on / off state of the relay. By changing the on / off state of the relay, the current flowing through the leakage protection switch in the circuit can be changed, thereby changing the on / off state of the leakage protection switch. Furthermore, when the leakage protection switch detects an imbalance between the live current and the neutral current within it, it immediately disconnects to disconnect the electrical connection between the mains power supply and the power supply component, making it impossible for the power supply component to supply power to the compressor 20. At this time, the electrical connection between the connector 10 and the compressor 20 is disconnected, which can effectively prevent the leakage of refrigerant from burning due to ignition of the internal circuit after the connector 10 and the compressor 20 are electrically connected.

[0198] In the embodiment of the present application, the detection component 30 is installed on the side of the connector 10 away from the compressor 20. Compared with installing the detection component 30 on the side of the connector 10, the detection component 30 is farther away from the compressor 20 and is less affected by the high temperature generated when the compressor 20 and the connector 10 are electrically connected, thereby not easily affecting the service life of the detection component 30.

[0199] Continuing to refer to FIG25 and FIG27 , FIG27 shows a schematic cross-sectional view of the structure along the FF direction in FIG26 . A mounting groove 1131 is provided on the connector 10, and at least a portion of the detection member 30 is located in the mounting groove 1131. The provision of the mounting groove 1131 can, on the one hand, locate the mounting position of the detection member 30 on the connector 10, thereby speeding up the assembly of the detection member 30 and the connector 10. On the other hand, it can constrain the detection member 30, making it difficult for the detection member 30 to move, thereby improving the connection reliability between the detection member 30 and the connector 10.

[0200] Furthermore, the first end face 113 of the connector 10 is provided with a mounting groove 1131, and the surface 31 of the bottom of the detection member 30 facing away from the mounting groove 1131 smoothly transitions with the first end face 113. In this way, after the detection member 30 is installed on the connector 10, the flatness of the first end face 113 of the connector 10 can be improved.

[0201] In one embodiment, the compressor assembly 1 includes a plurality of detection members 30, which are spaced apart on the connector 10. Thus, the accuracy of the detection members 30 in detecting whether a refrigerant leak exists can be further improved by using the plurality of detection members 30. It is understandable that, since the refrigerant content at different locations on the connector 10 is different, providing a plurality of detection members 30 for detection at different locations of the connector 10 can more comprehensively and promptly identify whether a refrigerant leak exists in the surrounding area, thereby further improving the safety performance of the connector 10 and the compressor 20 after being electrically connected.

[0202] Among them, multiple detection parts 30 can be arranged on the first end face 113 of the connector 10 away from the compressor 20; they can also be arranged on the side of the connector 10; or some can be arranged on the first end face 113 of the connector 10 away from the compressor 20, and the other part can be arranged on the side of the connector 10, etc., without limitation.

[0203] In one embodiment, the detection element 30 may include a refrigerant sensor for detecting the refrigerant concentration in the air. The control element is electrically connected to the refrigerant sensor and is configured to control the compressor 20 to shut down when the refrigerant concentration exceeds a first preset value. The first preset value is an explosive content value of the refrigerant in the air.

[0204] It should be noted that when the detection member 30 includes a refrigerant sensor, it is necessary to ensure that the detection portion of the refrigerant sensor is at least partially exposed to the air, that is, the refrigerant concentration in the air can only be detected after the detection portion is in contact with the air.

[0205] In another embodiment, the detecting element 30 includes a temperature sensor for detecting the temperature of the air. The control element is electrically connected to the temperature sensor for controlling the compressor 20 to stop when the temperature exceeds a second preset value.

[0206] In another embodiment, the detection member 30 includes a thermal fuse, which is used to detect the air temperature. When the temperature exceeds a second predetermined value, the fuse automatically opens, thereby shutting down the compressor 20. It should be noted that after the thermal fuse detects that the air temperature exceeds the second predetermined value and automatically melts, it must be replaced before it is used again.

[0207] The compressor assembly 1 also includes an alarm component, and the control component is electrically connected to the alarm component. The setting of the alarm component can issue an alarm in time when the detection component 30 detects refrigerant leakage, further improving the safety factor after the connector 10 and the compressor 20 are electrically connected.

[0208] Continuing with Figures 25 and 27 , connector 10 includes a housing 11 and connector terminals 12. Housing 11 defines a first chamber 1117 and a first port 1111 communicating with first chamber 1117. Connector terminals 12 are located within first chamber 1117. Detection member 30 is mounted on housing 11 of connector 10. Compressor 20 includes a casing and compressor terminals 21. At least a portion of compressor terminals 21 is located outside the casing. Compressor terminals 21 are configured to extend through first port 1111 and into first chamber 1117 to electrically connect with connector terminals 12.

[0209] The connector 10 may include at least two connector terminals 12, and the housing 11 may be formed with at least two first cavities 1117, the number of which is equal to the number of the at least two connector terminals 12, with each connector terminal 12 being mounted in a one-to-one correspondence within each first cavity 1117. For example, the connector 10 may include two connector terminals 12 and the housing 11 may be formed with two first cavities 1117; alternatively, the connector 10 may include three connector terminals 12 and the housing 11 may be formed with three first cavities 1117, and so on, without limitation.

[0210] It can be understood that when the connector 10 includes at least two connector terminals 12 , the compressor 20 includes at least two compressor terminals 21 equal in number to the at least two connector terminals 12 , and each compressor terminal 21 is electrically connected to each connector terminal 12 in a one-to-one correspondence.

[0211] Connector 10 also includes a seal 17, which is located on a side of housing 11 near the casing and at least partially protrudes from housing 11. When viewed along first port 1111, seal 17 is arranged around first port 1111. The provision of seal 17 seals the interface between connector 10 and compressor 20. The portion of seal 17 that protrudes from housing 11 is compressed when connector 10 and compressor 20 are connected, thereby enhancing the tightness of the connection between connector 10 and compressor 20.

[0212] In some embodiments, the housing 11 may include a first housing portion 111 and a second housing portion 112 connected to the first housing portion 111. The first housing portion 111 is closer to the casing than the second housing portion 112. The first housing portion 111 has a first port 1111. The heat resistance of the first housing portion 111 is higher than that of the second housing portion 112. The detection member 30 is installed in the second housing portion 112. The detection member 30 is installed in the second housing portion 112 so that the detection member 30 can be away from the casing of the compressor 20. Therefore, during the process of electrically connecting the connector 10 to the compressor 20, the detection member 30 is not easily affected by the high temperature of the casing of the compressor 20. When the detection member 30 is a temperature sensor, the detection result is more reliable.

[0213] The first housing portion 111 is formed with a first port 1111 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. 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 facilitates assembly of the connector terminal 12.

[0214] Referring to Figures 24, 26, and 27, connector 10 further includes a first connector 13 having a connection hole 133. Compressor 20 further includes a second connector 22 extending through connection hole 133. Compressor assembly 1 further includes a locking member 40 located on the side of first connector 13 away from compressor 20 and connected to second connector 22, thereby pressing connector 10 against compressor 20. The arrangement of first connector 13, second connector 22, and locking member 40 allows connector 10 and compressor 20 to be connected and secured. When locking member 40 is tightened, it compresses second portion 172 of seal 17 outside annular groove 1113, thereby enhancing the sealing performance of seal 17.

[0215] The second connector 22 and the locking member 40 can be connected via 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 connection hole 133 and is threadedly connected to the nut. By tightening the nut, the distance between the compressor 20 and the connector 10 can be shortened. Furthermore, the first connector 13 and the second connector 22 can also be connected via plug-in connection, snap-fit ​​connection, or other methods, which are not limited to this.

[0216] In the embodiment of the present application, the compressor 20 is provided with a second connector 22, which passes through the connection hole 133 of the first connector 13. The compressor 20 also includes a locking member 40, which is located on the side of the first connector 13 away from the compressor 20 and connects to the second connector 22 to achieve a secure connection between the connector 10 and the compressor 20. In other words, the provision of the first connector 13, the second connector 22, and the locking member 40 can securely connect the connector 10 and the compressor 20 when they are plugged into each other.

[0217] Referring to Figures 22 and 23 , Figure 22 is a partial front view of a HVAC system provided in some further embodiments of the present application, and Figure 23 is a cross-sectional view taken along the DD direction in Figure 22 , the connector 10 may further include a seal 17. The housing 11 has a first end face 113 and a second end face 114 that oppose each other along a first direction x. The second end face 114 defines a first port 1111. The seal 17 is located on the side of the housing 11 where the second end face 114 resides, and at least partially protrudes beyond the second end face 114, the first mating surface 136, and the second mating surface 161. The seal 17 is disposed around the first port 1111. The provision of the seal 17 seals the interface between the connector 10 and the compressor 20. The portion of the seal 17 that protrudes beyond the second end face 114, the first mating surface 136, and the second mating surface 161 can be compressed when the connector 10 and the compressor 20 are connected, thereby enhancing the tightness of the connection between the connector 10 and the compressor 20.

The HVAC system may include an air conditioner, a multi-split unit, a heat pump, or other systems for heating or cooling, which is not limited in the embodiment of the present application.
