[0044] 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.

[0045] 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.

[0046] Embodiment 1

[0047] 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.

[0048] See also Figure 1 and Figure 2 The HVAC system includes a connector 10 and a compressor 20, and the connector 10 is electrically connected to the compressor 20. The connector 10 and the compressor 20 are connected and fixed approximately in the middle of the connector 10 to ensure the reliability of the electrical connection between the connector 10 and the compressor 20, and to improve the problem of the connector being lifted on the opposite side to the compressor due to the unilateral fixing of the connector and the compressor.

[0049] Specifically, see Figures 1 to 5The connector 10 includes a housing 11, the housing 11 has a first end face 113 and a second end face 114 opposite to each other along a first direction x, and a first port 1111 is formed on the second end face 114. The first port 1111 is used for the compressor terminal 21 of the compressor 20 to extend into the housing 11, so as to realize the electrical connection between the connector 10 and the compressor 20. The housing 11 is also formed with a through hole 116 that penetrates the housing 11 along the first direction x, and the through hole 116 is located in the first port 1111. The through hole 116 is used for the connector 22 of the compressor 20 to extend into after passing through the first port 1111, so as to connect the connector 10 to the compressor 20.

[0050] In the above-mentioned design, the through hole 116 on the connector 10 for connecting with the connecting piece 22 of the compressor 20 is located inside the first port 1111. Compared with the related art in which the connecting hole on the connector for connecting the connecting piece is located outside the first port, and in terms of the single-sided connection of the connector with the compressor through the connecting piece, the through hole 116 can be roughly located in the middle of the connector 10, so that the connecting piece 22 located in the through hole 116 is roughly in the middle of the connector 10, and the connection between the connector 10 and the compressor 20 is realized, thereby improving the problem of the connector warping on the opposite side where the compressor is fixed due to the single-sided fixation of the connector and the compressor.

[0051] It should be noted that the through hole 116 may be located at the center of the first port 1111 ; the through hole 116 may also be offset from the center of the first port 1111 , which is not limited thereto.

[0052] The connector 10 and the compressor 20 are connected through the connector 22 extending into the through hole 116. The connector 22 may be connected to the locking member 40 on one side passing through the through hole 116, so that the connector 10 and the compressor 20 are connected and fixed. The connector 22 and the locking member 40 may be connected by threads. For example, the locking member 40 includes a nut, and the connector 22 is provided with threads. After the connector 22 passes through the through hole 116, it 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.

[0053] Of course, the connecting member 22 extending into the through hole 116 may also be connected to the inner wall of the through hole 116 by snapping or other means, which is not limited to this.

[0054] See also Figure 3 The connector 10 further includes a connector terminal 12 for electrically connecting to the compressor terminal 21. 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.

[0055] 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.

[0056] 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 connector 10 and the compressor 20 are fixed by the connecting piece 22, 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.

[0057] See also Figure 3 The housing 11 is formed with a first chamber 1117. When viewed along the first port 1111, the first chamber 1117 is located in the first port 1111, and the first chamber 1117 is communicated with the first port 1111. The connector terminal 12 is located in the first chamber 1117. In this way, the compressor terminal 21 can extend into the first chamber 1117 through the first port 1111 and be electrically connected to the connector terminal 12. The provision of the first chamber 1117 is conducive to positioning the assembly position of the connector terminal 12 in the housing 11.

[0058] The first cavity 1117 can be separated from the through hole 116. In this way, the connector terminal 12 disposed in the first cavity 1117 and the connecting member 22 disposed in the through hole 116 can be separated to achieve mutual insulation.

[0059] The connector 10 may include a plurality of connector terminals 12, and the housing 11 may be formed with a plurality of first chambers 1117, and each connector terminal 12 may be located in each first chamber 1117 in a one-to-one correspondence. For example, the connector 10 may include two connector terminals 12, and the housing 11 may be formed with two first chambers 1117; or, the connector 10 may include three connector terminals 12, and the housing 11 may be formed with three first chambers 1117, and so on, without limitation.

[0060] 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.

[0061] Combination Figure 3When the connector 10 includes a plurality of connector terminals 12 and a plurality of first chambers 1117, when viewed along the first port 1111, the through hole 116 is located between the plurality of first chambers 1117. In this way, when the connector 10 and the compressor 20 are connected via the connector 22 disposed in the through hole 116, the connector 22 is located between the plurality of connector terminals 12, so that the connection forces received at the respective connector terminals 12 are substantially similar, thereby ensuring the reliability of the electrical connection between the respective connector terminals 12 and the compressor terminals 21.

[0062] See also Figures 2 to 4 The housing 11 is formed with a second chamber 1118, which extends from the second end surface 114 toward the first end surface 113, and the second chamber 1118 forms a first port 1111 on the second end surface 114. When the connector 10 is connected to the compressor 20, the second chamber 1118 is closer to the compressor 20 than the first chamber 1117. The provision of the second chamber 1118 can reduce the docking area between the connector 10 and the compressor 20, and reduce the precision design requirements of the docking surface of the connector 10.

[0063] See also Figure 2 , along the first direction x, 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 first direction x, the cross-sectional profiles of all the first chambers 1117 are located within the cross-sectional profiles of the second chamber 1118. In this way, when the connector 10 includes a plurality of connector terminals 12 and the compressor 20 includes a plurality of compressor terminals 21, when the compressor terminals 21 are connected to the connector terminals 12, all the compressor terminals 21 can pass through the second chamber 1118 and reach the corresponding first chamber 1117 to achieve electrical connection with the corresponding connector terminals 12.

[0064] See also Figure 2 The compressor 20 may include a terminal seat 23 for fixing the compressor terminal 21, the terminal seat 23 protrudes relative to the compressor body, and when the compressor terminal 21 is connected to the connector terminal 12, the terminal seat 23 may be located in the second chamber 1118. In this way, the sealing performance between the connector 10 and the compressor 20 can be improved.

[0065] See also Figure 2 The connector 10 may further include a connecting sleeve 13, which is located in the second chamber 1118 and connected to a bottom wall 1119 of the second chamber 1118 away from the second end surface 114. The connecting sleeve 13 is disposed around the periphery of the through hole 116 and is used to be sleeved around the periphery of the connector 22. The connecting sleeve 13 may wrap the portion of the connector 22 located in the second chamber 1118 to prevent the connector 22 from being exposed.

[0066] The connecting sleeve 13 may be extended from the bottom wall 1119 of the outer shell 11, that is, the connecting sleeve 13 and the bottom wall 1119 are an integrally formed structure; the connecting sleeve 13 may also be formed independently and then connected to the bottom wall 1119 of the outer shell 11, which is not limited thereto.

[0067] See also Figure 2 The connector 10 may include a first seal 161, which is used to be sleeved around the outer periphery of the connector 22, and the first seal 161 is used to abut between the connector sleeve and the compressor 20. In this way, when the connector 10 and the compressor 20 are connected via the connector 22, the first seal 161 can achieve sealing at the connector 22 to prevent dust, water, etc. from entering the connector 10 from the through hole 116.

[0068] It should be noted that the connector 22 can be a metal part or a non-metal part. If the connector 22 is a metal part, the above-mentioned connection sleeve 13 can be set to wrap the upper part of the connector 22 in the second chamber 1118, so as to prevent the electrical connection part of the compressor terminal 21 extending into the first chamber 1117 from directly creeping horizontally to the upper part of the connector 22. Instead, it is necessary to creep along the compressor terminal 21 to the bottom of the compressor terminal 21 first, and then creep horizontally to the lower part of the connector 22 that is not wrapped by the connection sleeve 13, thereby increasing the creepage distance and meeting the power design requirements.

[0069] Furthermore, the arrangement of the connecting sleeve 13 and the first sealing member 161 can seal the portion of the connecting member 22 in the second chamber 1118 by the connecting sleeve 13 and the first sealing member 161, thereby preventing the compressor terminal 21 from creeping to the connecting member 22 in the second chamber 1118. In this way, when the connector 10 is connected to the compressor 20, it is only necessary to ensure that the spacing between the compressor terminals 21 of the compressor 20 is sufficient so that the creepage spacing between the compressor terminals 21 meets the requirements, without the need to design the spacing between the connecting member 22 and the compressor terminal 21 to be large enough, that is, without the need to design the spacing between the through hole 116 and the connector terminal 12 to be large enough, thereby reducing the size of the connector 10.

[0070] It should be noted that it is also possible not to design the connecting sleeve 13 or the first sealing member 161, but to design the spacing between each compressor terminal 21 and the connecting member 22 to be large enough so that the creepage distance from the compressor terminal 21 to the connecting member 22 is sufficient to meet the power design requirements.

[0071] Of course, an insulating layer may also be provided on the surface of the connector 22 to prevent the compressor terminal 21 from creeping onto the connector 22. The insulating layer may be provided on the surface of the connector 22 by spraying an insulating coating or sintering an insulating material, which is not limited.

[0072] See also Figure 6 The connector 10 may further include a second sealing member 162, which is located in the connection sleeve 13 and / or in the through hole 116, and is used to be sleeved around the periphery of the connection member 22. The second sealing member 162 can achieve a seal between the connector 10 and the connection member 22, and prevent dust, water, etc. from entering the connector 10 from the through hole 116. A sealing groove for placing the second sealing member 162 may be provided in the connection sleeve 13 and / or in the through hole 116, and this is not limited.

[0073] In the embodiment of the present application, the second sealing member 162 is disposed on one side of the through hole 116 close to the first end surface 113. Thus, when the locking member 40 is connected to the connecting member 22, the second sealing member 162 can be squeezed to improve the sealing performance between the connecting member 22 and the connector 10.

[0074] See also Figure 2 and Figure 4 The connector 10 further includes a third seal 17, at least a portion of which protrudes from the second end surface 114, the third seal 17 is disposed around the periphery of the first port 1111, and the third seal 17 is used to abut against the compressor 20. The third seal 17 can achieve sealing between the connector 10 and the compressor 20. The portion of the third seal 17 protruding from the second end surface 114 can be compressed when the connector 10 and the compressor 20 are fixed, so as to improve the tightness of the connection between the connector 10 and the compressor 20.

[0075] It is understandable that the two opposite sides of the third 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 third 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 third seal 17 and the housing 11, the third seal 17 and the housing 11 can be connected by means of adhesives or the like to prevent the third seal 17 from falling off.

[0076] 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 third 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 third seal 17 on the outer shell 11, thereby speeding up the assembly speed between the third seal 17 and the outer shell 11; on the other hand, it can restrain the third seal 17 and accommodate the deformation of the third seal 17 caused by extrusion so that it is not easy to move.

[0077] The part of the third sealing member 17 located in the annular groove 1113 may be: the third sealing member 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 connector 10 is connected to the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.

[0078] The third sealing member 17 can be installed in the annular groove 1113 by snap-fitting, or by bonding or other methods, which is not limited to this.

[0079] 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 third sealing member 17 from deforming toward the second chamber 1118 when it is squeezed and deformed, thereby affecting the installation stability of the third sealing member 17.

[0080] The third seal 17 can be any device with sealing performance, such as a sealing ring, etc. In the embodiment of the present application, the third seal 17 is a device with elasticity and high heat resistance, wherein the third seal 17 has elasticity, so that when the connector 10 is connected to the compressor 20, the third 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 third seal 17 has high heat resistance, which can prevent the third seal 17 from being damaged by the surface heat of the compressor 20, and can improve the service life of the third seal 17. Specifically, the third seal 17 can be a silicone rubber third seal, which has low cost and is elastic and highly heat resistant.

[0081] Next, the connector 10 will be further described.

[0082] In some embodiments, the housing 11 may include a first housing portion 111 and a second housing portion 112, wherein the first housing portion 111 is formed with a first port 1111, a first chamber 1117, and a second port 1114 communicating with the first chamber 1117, the connector terminal 12 is mounted on the first housing portion 111 via the second port 1114, and the second housing portion 112 is connected to the first housing portion 111. Disassembling the housing 11 into the first housing portion 111 and the second housing portion 112 is beneficial to assembling the connector terminal 12. The through hole 116 may penetrate the first housing portion 111 and the second housing portion 112. The first housing portion 111 may be provided with a second chamber 1118.

[0083] It should be noted that when a plurality of 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 .

[0084] 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.

[0085] If the connector 10 includes a third seal 17, the third seal 17 is connected to the first housing portion 111. The third 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 third seal 17 and the first housing portion 111, the first housing portion 111 is not easily deformed, and thus the third seal 17 can be stably supported, 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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 third sealing member 17, so that the overall sealing of the connector 10 can be improved.

[0091] When the second shell part 112 includes an injection molded shell part or a glue-filled shell part, in order to prevent the molding material of the second shell part 112 from penetrating into the through hole 116, a push rod can be provided to participate in forming the molding cavity of the second shell part 112, and the push rod can be pulled out after molding is completed.

[0092] 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.

[0093] 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, and the other may be provided with a slot adapted to the hook, and the hook is located in the slot. The second housing part 112 and the first housing part 111 can be hooked by the hook and are not easy to separate. It is understandable that the second housing part 112 may be provided with a hook, and the first housing part 111 may be provided with a slot; or the second housing part 112 may be provided with a slot, and the first housing part 111 may be provided with a hook, and this is not limited.

[0094] 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 .

[0095] 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.

[0096] 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.

[0097] 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. The through hole 116 may penetrate the cover plate 14 or may be arranged away from the cover plate 14, and may be flexibly designed in accordance with actual needs, and is not limited thereto.

[0098] 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.

[0099] If the housing 11 is formed with a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0100] 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.

[0101] Embodiment 2

[0102] The difference between this embodiment and the first embodiment is that: Figure 6 The connection surface 131 of the connection sleeve 13 away from the bottom wall 1119 is used to abut the compressor 20. In this way, the connection sleeve 13 can completely wrap the part of the connector 22 in the second chamber 1118, and the compressor terminal 21 can be prevented from creeping to the connector 22 in the second chamber 1118.

[0103] Furthermore, the connector 10 further includes a second sealing member 162, which is located in the connection sleeve 13 and / or in the through hole 116, and is used to be sleeved around the periphery of the connection member 22. The second sealing member 162 can achieve sealing between the connector 10 and the connection member 22, and prevent dust, water, etc. from entering the connector 10 from the through hole 116. A sealing groove for placing the second sealing member 162 can be provided in the connection sleeve 13 and / or the through hole 116, and this is not limited.

[0104] In the embodiment of the present application, the second sealing member 162 is disposed on one side of the through hole 116 close to the first end surface 113. Thus, when the locking member 40 is connected to the connecting member 22, the second sealing member 162 can be squeezed to improve the sealing performance between the connecting member 22 and the connector 10.
