[0041] 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.

[0042] 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.

[0043] 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.

[0044] See also Figure 1 The HVAC system includes a connector 10, a compressor 20 and a fixing structure 30. The connector 10 and the compressor 20 are plugged into each other to realize the electrical connection between the connector terminal 12 of the connector 10 and the compressor terminal 21 of the compressor 20. Figure 6 The fixing structure 30 is used to fix the connector 10 and the compressor 20 which are electrically connected.

[0045] That is, when the fixing structure 30 is used, the connector 10 and the compressor 20 are first plugged and electrically connected, and then the electrically connected connector 10 and the compressor 20 are fixed by the fixing structure 30 .

[0046] After the connector and the compressor are electrically connected, in the related art, the connector and the compressor are usually fixed only by a first connecting member located on one side of the connector. This will cause the side of the connector away from the first connecting member to be tilted relative to the compressor. Figure 1 and Figure 2The fixing structure 30 of the embodiment of the present application is designed to include a first connecting member 31 and a pressing plate 32. The pressing plate 32 has a pressing surface 321 and a back surface 322 that are opposite to each other along the first direction x. The pressing plate 32 is located at an end of the connector 10 away from the compressor 20, and the pressing surface 321 faces the connector 10. The first connecting member 31 is connected to the pressing plate 32. The first connecting member 31 is located at one side of the connector 10. The first connecting member 31 is connected to the compressor 20 so that the pressing surface 321 presses the connector 10.

[0047] Specifically, the fixing structure 30 of the embodiment of the present application is connected to the compressor 20 through the first connecting member 31 on the side of the connector 10, and is pressed by the pressure plate 32 at the end of the connector 10 away from the compressor 20. In this way, the connecting force between the first connecting member 31 on the side and the compressor 20 can be transmitted to the pressure plate 32, and the connector 10 is pressed by the pressure plate 32, thereby improving the problem in the related art that the connector is only connected to the compressor on one side and causes the other side to be lifted up.

[0048] 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 fixing structure 30 fixes 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.

[0049] The pressing plate 32 may cover at least a portion of the first end surface 113 of the connector 10 away from the compressor 20. Thus, the pressing surface 321 may at least press the portion of the first end surface 113 that it covers.

[0050] For example, in some embodiments, see Figure 1 and Figure 2 , the pressure plate 32 covers the entire first end surface 113. At this time, the pressure of the pressure plate 32 on each part of the first end surface 113 of the connector 10 can be relatively evenly distributed, which can better prevent the connector 10 from tilting relative to the compressor 20 on the side away from the first connector 31.

[0051] For example, in some other embodiments, see Figure 3 and Figure 4 , the pressing plate 32 covers a part of the first end surface 113. In this case, the size of the fixing structure 20 can be reduced. For example, the pressing plate 32 covers a part of the edge area of ​​the first end surface 113 close to the first connecting member 31, a part of the edge area of ​​the first end surface 113 away from the first connecting member 31, a middle area 1131 of the first end surface 113, etc., which is not limited to this.

[0052] It should be noted that if the area of ​​the first end surface 113 covered by the pressing plate 32 is not close to the first connecting member 31, see Figure 3 and Figure 4 The fixing structure 30 may further include a connecting plate 35 connecting the pressing plate 32 and the first connecting member 31, and the connecting plate 35 is used to be spaced apart from the first end face 113 of the connector 10. That is, the connecting plate 35 plays a role of connecting the pressing plate 32 and the first connecting member 31, and does not press the first end face 113.

[0053] In the present application, see Figure 3 and Figure 4 The partial area of ​​the first end surface 113 covered by the pressing plate 32 is the middle area 1131 of the first end surface 113, and the pressing plate 32 is connected to the first connector 10 through the connecting plate 35. In this way, the pressing plate 32 can press the middle area 1131 of the first end surface 113, which can better improve the problem of the connector 10 warping on the side away from the first connector 31.

[0054] It should be noted that the first end surface 113 may include an edge area arranged outside the middle area in addition to the middle area 1131. The middle area 1131 may include the center point of the first end surface 113, or may be offset to a certain extent relative to the center point of the first end surface 113, so as to reduce the setting accuracy of the pressing plate 32 and reduce the assembly cost, which is not limited thereto.

[0055] See also Figure 1 and Figure 2 The fixing structure 30 may further include a protrusion 33, which is located on one side of the pressing surface 321 of the pressing plate 32 and protrudes outward from the pressing surface 321. A first accommodating area 34 for accommodating at least part of the connector 10 is defined between the protrusion 33 and the pressing surface 321. The first accommodating area 34 facilitates the rapid alignment of the fixing structure 30 and the connector 10, and enhances the mutual constraint between the fixing structure 30 and the connector 10, so as to better realize the pressing of the pressing plate 32 on the connector 10.

[0056] For example, in some embodiments, the protrusion 33 and the first connecting member 31 are located on opposite sides of the pressure plate 32, and a first accommodation area 34 is formed between the protrusion 33, the first connecting member 31 and the pressing surface 321. In this way, the protrusion 33 and the first connecting member 31 can constrain the opposite sides of the connector 10 located in the first accommodation area 14, which can reduce the difficulty of assembling and aligning the fixing structure 30 and the connector 10 compared to constraining the entire circle of the connector 10. At this time, the protrusion 33 can be connected to the pressure plate 32.

[0057] For another example, in some other embodiments, the protrusion 33 is arranged around the first direction x. In this way, when at least a portion of the connector 10 is placed in the first accommodation interval 34, the protrusion 33 can be arranged around the periphery of the connector 10, which can have a restraining effect on the entire circle of the connector 10, and the alignment and restraining effect of the connector 10 is better. At this time, the protrusion 33 can be connected to the pressure plate 32 and / or the first connecting member 31.

[0058] The first connecting member 31 and the pressing plate 32 in the fixed structure 30 can be an integrally formed structure. In this way, the manufacturing cost of the fixed structure 30 can be simplified and the connection strength between the first connecting member 31 and the pressing plate 32 can be improved. For example, the first connecting member 31 and the pressing plate 32 can be integrally formed by a process such as injection molding, which is not limited to this. Of course, the first connecting member 31 and the pressing plate 32 can also be separately formed and then connected to each other. For example, the first connecting member 31 and the pressing plate 32 can be connected by welding, clamping, screwing, etc., which is not limited to this.

[0059] Optionally, the fixing structure 30 as a whole can be an integrally formed structure to improve the structural strength of the fixing structure 30. For example, when the fixing structure 30 includes a first connecting member 31, a pressing plate 32, a protrusion 33 and a connecting plate 35, the first connecting member 31, the pressing plate 32, the protrusion 33 and the connecting plate 35 can be integrally formed, and this is not limited.

[0060] The fixing structure 30 of the embodiment of the present application may be made of high-strength materials. For example, the fixing structure 30 may be a metal part and / or a plastic part, etc., which is not limited to this.

[0061] The first connector 31 is connected to the compressor 20 along the first direction x, and can be: the first connector 31 is provided with a connecting hole 311, and the connecting hole 311 is used to sleeve the second connector 22 of the compressor 20. Further, the second connector 22 can be connected to the locking member 40 on one side passing through the connecting hole 311, so that the connector 10 presses against the compressor 20.

[0062] The second connector 22 and the locking member 40 may 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 connection hole 311 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.

[0063] In some embodiments, see Figure 5 A second accommodation area 115 is disposed on the side of the connector 10, and at least a portion of the first connecting member 31 is located in the second accommodation area 115. In this way, the connection stability between the connector 10 and the fixing structure 30 can be improved. Figure 5The second accommodation area 115 is located on one side of the first connection member 31 of the fixing structure 30 to reduce the size of the connector 10. Of course, the second accommodation area 115 can also be arranged around the periphery of the first connection member 31 of the fixing structure 30, which is not limited.

[0064] Furthermore, a guide block or a guide groove extending along the first direction x may be provided in the second accommodation interval 115, and the first connecting member 31 of the fixed structure 30 may be provided with the other of the guide block and the guide groove, and the guide block may be slidably disposed in the guide groove. In this way, the connection stability between the connector 10 and the fixed structure 30 may be further improved.

[0065] See also Figures 1 to 4 , along the first direction x, the distance between the pressing surface 321 of the pressure plate 32 and the first surface 312 of the first connector 31 facing the compressor 20 is H1, and along the first direction x, the distance between the first end surface 113 of the connector 10 and the second end surface 114 of the connector 10 facing the compressor 20 is H2, H1≤H2. In this way, it can be ensured that when the first connector 31 is connected to the compressor 20, the connector 10 and the compressor 20 can be pressed tightly.

[0066] If H1<H2, after the fixing structure 30 presses and fixes the connector 10 and the compressor 20, the first connector 31 is roughly spaced apart from the compressor 20, which can ensure that the first connector 31 has a sufficient downward stroke to achieve the tight contact between the connector 10 and the compressor 20. If H1=H2, while the fixing structure 30 presses and fixes the connector 10 and the compressor 20, the first surface 312 of the first connector 31 is roughly in contact with the compressor 20, which can provide a good support effect on the pressure plate 32.

[0067] See also Figure 6 The connector 10 may further include a seal 17, at least a portion of which protrudes from the second end surface 114. The seal 17 may seal the interface between the connector 10 and the compressor 20. The portion of the seal 17 that protrudes from the second end surface 114 may be compressed when the fixing structure 30 fixes the connector 10 and the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.

[0068] It is understandable that the two opposite sides of the seal 17 can respectively abut the surface of the compressor 20 and the housing 11 of the connector 10 to achieve sealing between the surface of the compressor 20 and the housing 11. In an exemplary solution, the seal 17 can be provided on the second end surface 114 of the housing 11. At this time, in order to achieve a reliable connection between the seal 17 and the housing 11, the seal 17 and the housing 11 can be connected by means of an adhesive or the like to prevent the seal 17 from falling off.

[0069] In another exemplary embodiment, the second end face 114 of the outer 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 setting of the annular groove 1113 can, on the one hand, locate the installation position of the seal 17 on the outer shell 11, thereby speeding up the assembly speed between the seal 17 and the outer shell 11; on the other hand, it can restrain the seal 17 and accommodate the deformation of the seal 17 caused by extrusion so that it is not easy to move.

[0070] The portion of the seal 17 located in the annular groove 1113 may be: the seal 17 includes 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 in 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 be deformed when the fixing structure 30 fixes the connector 10 and the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.

[0071] The sealing member 17 may be installed in the annular groove 1113 by snap-fitting, or may be installed in the annular groove 1113 by bonding or the like, which is not limited thereto.

[0072] The seal 17 can be any device with sealing performance, such as a sealing ring, etc. In the embodiment of the present application, the seal 17 is a device with elasticity and high heat resistance, wherein the seal 17 has elasticity, 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; and 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 can improve the service life of the seal 17. Specifically, the seal 17 can be a silicone rubber seal, which has low cost and is elastic and highly heat-resistant.

[0073] Next, the connector 10 will be further described.

[0074] See also Figure 6 The connector 10 includes a housing 11 and a connector terminal 12, and the housing 11 is formed with a first chamber 1117. The connector terminal 12 is located in the first chamber 1117. The housing 11 is formed with a first port 1111 communicating with the first chamber 1117, and the connector terminal 12 is used to be electrically connected to the compressor terminal 21 extending into the first chamber 1117 via the first port 1111.

[0075] The connector 10 may include at least two connector terminals 12, and the housing 11 is formed with at least two first chambers 1117 equal in number to the at least two connector terminals 12, and each connector terminal 12 is mounted in a one-to-one correspondence in each first chamber 1117. For example, the connector 10 includes two connector terminals 12, and the housing 11 is formed with two first chambers 1117; or, the connector 10 includes three connector terminals 12, and the housing 11 is formed with three first chambers 1117, and so on, without limitation.

[0076] 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.

[0077] 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 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 the assembly of the connector terminal 12.

[0078] It should be noted that when at least two first chambers 1117 are formed on the housing 11 , the first housing portion 111 has second ports 1114 equal in number to the first chambers 1117 , and each second port 1114 is correspondingly connected to each first chamber 1117 .

[0079] 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.

[0080] 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, and even if the heat on 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, and thus can provide a stable support effect for the seal 17, 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.

[0081] 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.

[0082] 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 second end surface 114, and the second housing portion 112 may have a first end surface 113.

[0083] 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.

[0084] 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.

[0085] 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 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 17, so that the overall sealing of the connector 10 can be improved.

[0086] 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.

[0087] 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 1115, and the first housing part 111 may be provided with a hook 1121, and this is not limited.

[0088] 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 .

[0089] 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.

[0090] 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.

[0091] 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 .

[0092] 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.

[0093] If the housing 11 is formed with a plurality of first chambers 1117 and a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0094] The housing 11 (e.g., the first housing portion 111) may further include a second chamber 1118 in communication with the first chamber 1117, and a first port 1111 is formed on a side of the second chamber 1118 facing away from the first chamber 1117. The second chamber 1118 is closer to the compressor 20 than the first chamber 1117. Along the plugging direction, the cross-sectional profile of the second chamber 1118 is larger than the cross-sectional profiles of all the first chambers 1117, and along the plugging direction, the cross-sectional profiles of all the first chambers 1117 are located within the cross-sectional profile of the second chamber 1118. In this way, when the connector 10 includes at least two connector terminals 12 and the compressor 20 includes at least two 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. Furthermore, the compressor 20 may include a terminal seat 23 for fixing the compressor terminal 21 , and the terminal seat 23 protrudes relative to the compressor body. When the compressor terminal 21 is connected to the connector terminal 12 , the terminal seat 23 may be located in the second chamber 1118 .

[0095] It is understandable that the annular groove 1113 may or may not be connected to the second chamber 1118. In the embodiment of the present application, the annular groove 1113 is not connected to the second chamber 1118, which can prevent the seal 17 from deforming toward the second chamber 1118 when it is squeezed and deformed, thereby affecting the installation stability of the seal 17.

[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.

[0097] The connector terminal 12 may be any terminal, and the compressor terminal 21 may be any terminal, as long as the compressor terminal 21 and the connector terminal 12 can be electrically connected.

[0098] 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.
