[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe in detail the implementation manners of the embodiments of this application with reference to the accompanying drawings.

[0042] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] In a first aspect, please refer to Figures 1 to 5 , an embodiment of this application provides a connector 10, and the connector 10 includes a housing 11 and a seal 12. Among them, the housing 11 is formed with a first port 111. The housing 11 is provided with an annular groove 112 on one side where the first port 111 is located. The annular groove 112 is arranged around the first port 111. The annular groove 112 has an inner side wall 1121 and an outer side wall 1122 that are arranged around the first port 111. The inner side wall 1121 is located inside the outer side wall 1122. The seal 12 includes a first part 121 located in the annular groove 112. The first part 121 has an inner side surface 1211 and an outer side surface 1212 that are arranged around the first port 111. The inner side surface 1211 is located inside the outer side surface 1212. Among them, at least one of the inner side wall 1121, the outer side wall 1122, the inner side surface 1211, and the outer side surface 1212 is provided with a rib 13 so that the first part 121 is squeezed at the rib 13.

[0044] In an embodiment of the present application, ribs 13 are provided on at least one of the inner side wall 1121 and the outer side wall 1122 of the annular groove 112, and the inner side surface 1211 and the outer side surface 1212 of the seal 12, so that the first part 121 of the seal 12 located in the annular groove 112 can be squeezed at the ribs 13, increasing the compression amount of the first part 121 in the annular groove 112. At this time, the resilience of the first part 121 becomes larger. Under the mutual resistance between the resilience and the ribs 13, the connection tightness of the first part 121 in the annular groove 112 can be improved. Thus, during the transportation of the connector 10, the seal 12 is not easily dropped from the annular groove 112, improving the problem in the related art that when a flexible sleeve for sealing the connector 10 and the compressor 20 is easily dropped during the single-piece transportation of the connector 10.

[0045] It should be noted that the ribs 13 are provided on at least one of the above-mentioned inner side wall 1121, outer side wall 1122, inner side surface 1211 and outer side surface 1212. It can be that the ribs 13 are provided on any one of the inner side wall 1121, outer side wall 1122, inner side surface 1211 and outer side surface 1212; it can also be that the ribs 13 are provided on any two of the inner side wall 1121, outer side wall 1122, inner side surface 1211 and outer side surface 1212; it can also be that the ribs 13 are provided on any three of the inner side wall 1121, outer side wall 1122, inner side surface 1211 and outer side surface 1212, or the ribs 13 are provided on all of the inner side wall 1121, outer side wall 1122, inner side surface 1211 and outer side surface 1212, etc. It can be flexibly designed according to the actual situation and is not limited thereto.

[0046] Among them, the housing 11 is provided with an annular groove 112 on the side where the first port 111 is located. By providing the annular groove 112, on the one hand, the installation position of the seal 12 on the housing 11 can be positioned, accelerating the assembly speed between the seal 12 and the housing 11. On the other hand, a restraining effect can be exerted on the seal 12, and it can accommodate the deformation generated by the extrusion of the seal 12 and is not easily displaced.

[0047] It can be understood that the annular groove 112 can be communicated with the first port 111 or not. In the embodiment of the present application, the annular groove 112 is not communicated with the first port 111, which can prevent the seal 12 from deforming towards the inside of the first port 111 when being squeezed, affecting the installation stability of the seal 12. It should be noted that the seal 12 can be installed in the annular groove 112 by a clamping method or by an adhesive method, etc., and is not limited thereto.

[0048] On opposite sides of the first part 121 of the seal 12 located in the annular groove 112, they can respectively abut against the surface of the compressor 20 and the housing 11 of the connector 10, so as to achieve the sealing between the surface of the compressor 20 and the housing 11. In an exemplary solution, in order to achieve a reliable connection between the seal 12 and the housing 11, the seal 12 and the housing 11 can be connected by means such as adhesives, etc., to prevent the seal 12 from falling off.

[0049] The seal 12 further includes a second part 122 located outside the annular groove 112. The second part 122 is connected to the first part 121. When the connector 10 is connected to the compressor 20, the second part 122 can be deformed to improve the connection tightness between the connector 10 and the compressor 20.

[0050] Among them, the rib 13 can extend along the depth direction of the annular groove 112. In this way, when the seal 12 is placed in the annular groove 112, the first part 121 of the seal 12 located in the annular groove 112 can uniformly receive the extrusion force of the rib 13 in the depth direction of the annular groove 112, improving the stability of the seal 12 in the annular groove 112.

[0051] In one embodiment, refer to Figure 3 and Figure 4 , if at least one of the inner side wall 1121 and the outer side wall 1122 is provided with a rib 13, the rib 13 is provided with a guiding surface 131 at one end close to the notch 1123 of the annular groove 112. In this way, the guiding surface 131 can be used to improve the convenience of assembling the seal 12 into the annular groove 112.

[0052] Among them, the guiding surface 131 can be an inclined surface inclined relative to the depth direction of the annular groove 112, and the guiding surface 131 can also be an arc surface, etc., which is not limited thereto. Along the direction from the notch 1123 to the bottom of the annular groove 112, the inner diameter of the annular groove 112 at the guiding surface 131 gradually decreases. In this way, the caliber of the notch 1123 of the annular groove 112 can be made larger, facilitating the assembly of the seal 12 into the annular groove 112, improving the installation convenience of the seal 12 and the installation efficiency; and as the depth of the seal 12 inserted into the annular groove 112 increases, the seal 12 will be restricted by the rib 13 in the annular groove 112, so that the extrusion force received by the first part 121 of the seal 12 gradually increases, realizing a more stable assembly of the first part 121 in the annular groove 112.

[0053] It should be noted that after passing over the guiding surface 131, the inner diameter of the annular groove 112 at the rib 13 can remain unchanged to facilitate the smooth assembly of the seal 12.

[0054] Among them, if ribs 13 are provided on the inner side wall 1121 and / or the outer side wall 1122, the ribs 13 may extend to the notch 1123 of the annular groove 112 or may not extend to the notch 1123, and this is not limited.

[0055] In another embodiment, if ribs 13 are provided on at least one of the inner side surface 1211 and the outer side surface 1212, the first part 121 has an end away from the second part 122, and a guiding surface 131 is provided at one end of the rib 13 close to the end. That is, by adjusting the structure of the seal 1212, the manufacturing is more convenient. At this time, along the direction from the end of the first part 121 to the second part 122, the outer diameter of the first part 121 at the guiding surface 131 gradually increases, which is convenient for the seal 12 to be assembled into the annular groove 112 through the end; and as the depth of the seal 12 inserted into the annular groove 112 increases, the extrusion force generated by the rib 13 on the seal 12 will also become larger, so that the seal 12 is not easily detached from the annular groove 112.

[0056] It should be noted that after passing the guiding surface 131, the outer diameter of the first part 121 at the rib 13 can remain unchanged to facilitate the smooth assembly of the seal 12.

[0057] Among them, if ribs 13 are provided on the inner side surface 1211 and / or the outer side surface 1212, the ribs 13 may extend to the end of the first part 121 away from the second part 122 or may not extend to the end of the first part 121 away from the second part 122, and this is not limited.

[0058] Combined again Figure 1 and Figure 2 , the number of ribs 13 is multiple, and the multiple ribs 13 are arranged at intervals along the circumference of the first port 111. By providing multiple ribs 13, when the seal 12 is assembled into the annular groove 112, the first part 121 of the seal 12 can be squeezed at multiple places by the multiple ribs 13, thereby increasing the connection tightness between the first part 121 and the annular groove 112 and making the seal 12 not easily fall out of the annular groove 112. Arranging the multiple ribs 13 at intervals along the circumference of the first port 111 is beneficial to improving the uniformity of the extrusion of the first part 121 by the multiple ribs 13 compared with concentrating the multiple ribs 13 in a certain area.

[0059] The multiple ribs 13 arranged at intervals along the circumference of the first port 111 may be such that all the ribs 13 are provided in the annular groove 112; or all the ribs 13 are provided on the first part 121 of the seal 12, or part of the ribs 13 are provided in the annular groove 112 and the remaining ribs 13 are provided on the first part 121 of the seal 12, which can be flexibly designed according to the actual situation and is not limited thereto.

[0060] It should be noted that, in addition to being designed to extend along the depth direction of the annular groove 112 as described above, the convex rib 13 can also be designed such that the convex rib 13 is arranged in a ring around the first port 111. Arranging the convex rib 13 to be arranged in a ring around the first port 111 can improve the uniformity of the extrusion of the first part 121 by the convex rib 13 in the circumferential direction of the first port 111, make the compression amount of the first part 121 in the annular groove 112 more uniform, and thus make the assembly of the seal 12 in the annular groove 112 more stable.

[0061] For the convenience of assembling the seal 12 in the annular groove 112, referring to Figure 2 , along the radial direction of the first port 111, the width L1 of the convex rib 13 is less than or equal to half of the width L2 of the annular groove 112. In this way, while ensuring that the first part 121 is extruded at the convex rib 13, the installation convenience of the first part 121 in the annular groove 112 can be maintained. It can be understood that if the width L1 of the convex rib 13 is too large, the convex rib 13 will occupy too much space in the annular groove 112, and at this time, the seal 12 is easily blocked too much by the convex rib 13, which will easily cause problems in assembly. Exemplarily, along the radial direction of the first port 111, the width L1 of the convex rib 13 can be one-half, one-third, one-fourth, one-fifth, one-sixth, etc. of the width L2 of the annular groove 112, and no limitation is made thereto.

[0062] In order to improve the installation stability of the seal 12 in the annular groove 112, in one embodiment, the depth of the annular groove 112 is greater than the width of the annular groove 112 along the radial direction of the first port 111. In this way, the depth of the first part 121 of the seal 12 located in the annular groove 112 will be greater than the width of the first part 121 along the radial direction of the first port 111. And when the width of the first part 121 remains unchanged, the greater the depth of the first part 121, the more extrusion force the seal 12 receives from the convex rib 13, and thus a greater compression amount can be generated, that is, the resilience is also greater. Under the mutual resistance between the resilience and the convex rib 13, the first part 121 is not easily detached from the annular groove 112.

[0063] It should be noted that the above-mentioned seal 12 can be used at multiple positions on the connector 10. For example, the seal 12 can be used at the connection between the housing 11 of the connector 10 and the compressor 20. Another example is that the seal 12 can be used at the connection between the housing 11 of the connector 10 and the connecting wire 17, etc., and no limitation is made thereto.

[0064] In the embodiment of the present application, referring to Figure 6 and Figure 7, the seal 12 is used at the connection between the housing 11 of the connector 10 and the compressor 20. Specifically, the first port 111 is for the compressor terminal 22 of the compressor 20 to be inserted into the housing 11. After the compressor terminal 22 extends into the housing 11 through the first port 111 and is plugged into the connector terminal 16, the seal 12 can be used to seal the side where the first port 111 is located, ensuring the sealing performance between the connector 10 and the compressor 20.

[0065] Among them, the seal 12 can be any device with sealing performance. For example, an O-ring and so on. In the embodiment of the present application, the seal 12 is a device with elasticity and high heat resistance. Among them, the seal 12 has elasticity, so that when the connector 10 is connected to the compressor 20, the seal 12 can be in a compressed state to improve the connection tightness between the connector 10 and the compressor 20; and the seal 12 has high heat resistance, which can prevent the seal 12 from being damaged under the action of the surface heat of the compressor 20 and can improve the service life of the seal 12. Specifically, the seal 12 can be selected as a silicone rubber seal, and the silicone rubber has low cost and has elasticity and high heat resistance.

[0066] Refer to Figures 3 to 6 , the connector 10 further includes a first connecting member 14. The first connecting member 14 is provided with a connection hole 141. The compressor 20 is provided with a second connecting member 21, and the second connecting member 21 passes through the connection hole 141; the compressor 20 further includes a locking member 30. The locking member 30 is located on the side of the first connecting member 14 away from the compressor 20 and connects the second connecting member 21 to realize the connector 10 pressing against the compressor 20. The settings of the first connecting member 14, the second connecting member 21 and the locking member 30 can connect and fix the mutually plugged connector 10 and compressor 20. And when the locking member 30 is locked, the second part 122 outside the annular groove 112 of the seal 12 can be extruded to improve the sealing performance of the seal 12.

[0067] Among them, the second connecting member 21 and the locking member 30 can be connected by threads. For example, the locking member 30 includes a nut, and the second connecting member 21 is provided with threads. After the second connecting member 21 passes through the connection hole 141, 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 reduced. In addition, the first connecting member 14 and the second connecting member 21 can also be connected by plugging, snapping and other methods, which are not limited herein.

[0068] Next, the connector 10 will be further described.

[0069] Continue to refer to Figures 5 to 7, the connector 10 includes a housing 11 and connector terminals 16. The housing 11 is formed with a first chamber 115. The connector terminals 16 are located in the first chamber 115. The housing 11 is formed with a first port 111 communicating with the first chamber 115. The connector terminals 16 are used for electrically connecting with the compressor terminals 22 extending into the first chamber 115 via the first port 111.

[0070] The connector 10 may include at least two connector terminals 16. The housing 11 is formed with at least two first chambers 115 equal in number to the at least two connector terminals 16. Each connector terminal 16 is correspondingly mounted in each first chamber 115. For example, the connector 10 includes two connector terminals 16 and the housing 11 is formed with two first chambers 115; or, the connector 10 includes three connector terminals 16 and the housing 11 is formed with three first chambers 115, etc., which is not limited herein.

[0071] It can be understood that when the connector 10 includes at least two connector terminals 16, the compressor 20 includes at least two compressor terminals 22 equal in number to the at least two connector terminals 16. Each compressor terminal 22 is correspondingly electrically connected to each connector terminal 16.

[0072] In some embodiments, the housing 11 may include a first housing portion 113 and a second housing portion 114. The first housing portion 113 is formed with a first port 111 and a second port 117 communicating with the first chamber 115. The connector terminals 16 are mounted in the first housing portion 113 via the second port 117. The second housing portion 114 is connected to the first housing portion 113. Splitting the housing 11 into the first housing portion 113 and the second housing portion 114 is beneficial to the assembly of the connector terminals 16.

[0073] It should be noted that when at least two first chambers 115 are formed in the housing 11, the first housing portion 113 has first ports 111 equal in number to the first chambers 115 and second ports 117 equal in number to the first chambers 115. Each first port 111 communicates with each corresponding first chamber 115, and each second port 117 communicates with each corresponding first chamber 115.

[0074] Among them, the heat resistance of the first housing portion 113 is higher than that of the second housing portion 114. Compared with the second housing portion 114, the first housing portion 113 is less likely to deform under high temperature conditions. Thus, when the first port 111 is provided on the first housing portion 113, when the connector 10 is connected to the compressor 20, the first housing portion 113 is close to the compressor 20, and the first housing portion 113 has a high heat resistance, which can prevent the internal connector terminals 16 from being softened by high temperature and extend the service life of the connector terminals 16.

[0075] The first housing part 113 can be made of a high heat resistance material. For example, the first housing part 113 can include at least one of PBT (poly butylene terephthalate) and GF (glass fibre). In the embodiment of the present application, the first housing part 113 selects PBT + 30% GF, which is a high temperature resistant and fireproof insulating material and can prevent the connector terminals 16 from softening during operation.

[0076] The second housing part 114 can cover the second port 117 and the connector terminals 16. The setting of the second port 117 is beneficial to the installation of the connector terminals 16 in the housing 11. When the second housing part 114 covers the second port 117 and the connector terminals 16, the connector terminals 16 and the compressor terminals 22 can be wrapped by the housing 11 of the connector 10 when they are connected, avoiding the presence of refrigerant near them and thus easily causing a sparking problem when the connector terminals 16 and the compressor terminals 22 are connected.

[0077] The second housing part 114 can include an injection molded housing part connected to the first housing part 113, and / or the second housing part 114 can include a potted housing part connected to the first housing part 113. Among them, the injection molded housing part is formed by an injection molding process. When the injection molded housing part is connected to the first housing part 113, the injection molded housing part and the first housing part 113 are at least an injection molded integral structure. Specifically, after the first housing part 113 is formed, at least the first housing part 113 is placed in a mold to participate in constructing the cavity for forming the injection molded housing part, and then the molding material is injected into the cavity to obtain the injection molded housing part.

[0078] Among them, the potted housing part is formed by a potting process. When the potted housing part is connected to the first housing part 113, the potted housing part and the first housing part 113 are at least a potted integral structure. Specifically, the first housing part 113 is formed with a molding groove, and at least the molding groove participates in constructing the potting groove for forming the potted housing part, and then the molding material is injected into the potting groove to obtain the potted housing part.

[0079] In summary, whether the second housing part 114 includes an injection molded housing part or a potted housing part, it can achieve an integral structure of the second housing part 114 and the first housing part 113. Compared with the case where the second housing part 114 and the first housing part 113 are separately formed and then assembled, the connection tightness between the second housing part 114 and the first housing part 113 can be improved, and the sealing performance between the second housing part 114 and the first housing part 113 can be improved. There is a sealing performance between the second housing part 114 and the first housing part 113 of the connector 10, and there is a sealing performance between the first housing part 113 and the surface of the compressor 20 due to the presence of the seal 12 when the connector 10 is connected to the compressor 20. Thus, the overall sealing performance of the connector 10 can be improved.

[0080] Among them, the second housing part 114 can be a sealed rubber housing, which has high sealing performance. Among them, the second housing part 114 can be elastic or non-elastic, and can be flexibly designed according to actual needs. In the embodiment of the present application, the second housing part 114 can be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing performance. The second housing part 114 can be made of plastic or silica gel, and there is no limitation in this regard.

[0081] To improve the connection reliability between the second housing part 114 and the first housing part 113, one of the second housing part 114 and the first housing part 113 can be provided with a hook 1141, and the other can be provided with a slot 1131 adapted to the hook 1141, and the hook 1141 is located in the slot 1131. The second housing part 114 and the first housing part 113 can be hooked by the hook 1141 and are not easily separated. It can be understood that the hook 1141 can be provided on the second housing part 114, and the slot 1131 can be provided on the first housing part 113; or, the slot 1131 can be provided on the second housing part 114, and the hook 1141 can be provided on the first housing part 113, and there is no limitation in this regard.

[0082] It can be understood that the second housing part 114 can be integrally formed as an injection-molded housing part, or the second housing part 114 can be integrally formed as a potting housing part, so as to simplify the processing technology of the second housing part 114 and reduce the manufacturing cost of the connector 10.

[0083] The connector 10 further includes a covering member that covers the second port 117, and the second housing part 114 covers the covering member. Under the shielding of the covering member, water vapor, dust and other impurities can be prevented from entering the first housing part 113 and affecting the use performance of the connector terminal 16. And when the second housing part 114 includes an injection-molded housing part and a potting housing part, under the shielding of the covering member, the molding material of the second housing part 114 will not pass through the second port 117 to reach the connector terminal 16 and wrap the connector terminal 16, which can ensure the effective electrical connection between the connector terminal 16 and the compressor terminal 22.

[0084] Among them, there can be abutment or a gap between the connector terminal 16 and the covering member. If there is a gap between the connector terminal 16 and the covering member, the connector terminal 16 can be deformed towards the gap when being inserted into the compressor terminal 22, so as to avoid damage caused by hard insertion of the connector terminal 16 and the compressor terminal 22.

[0085] The covering member can include a cover plate 15 that covers the second port 117 and the connector terminal 16, and the second housing part 114 covers the cover plate 15.

[0086] One of the cover plate 15 and the first housing part 113 may be provided with a limiting protrusion 151, and the other may be provided with a limiting groove 1132, and the limiting protrusion 151 is located in the limiting groove 1132. The arrangement of the limiting protrusion 151 and the limiting groove 1132 can position the cover plate 15 and the first housing part 113 during assembly, which is beneficial to improving the assembly efficiency of the cover plate 15 and the first housing part 113. It can be understood that the cover plate 15 may be provided with the limiting protrusion 151, and the first housing part 113 may be provided with the limiting groove 1132; or, the cover plate 15 may be provided with the limiting groove 1132, and the first housing part 113 may be provided with the limiting protrusion 151, and this is not limited. In the embodiment of the present application, the cover plate 15 is provided with the limiting protrusion 151, and the first housing part 113 is provided with the limiting groove 1132. Since the cover plate 15 is relatively thin, therefore, setting the limiting protrusion 151 on the cover plate 15 is beneficial to improving the structural strength of the cover plate 15 compared with the limiting groove 1132.

[0087] If the housing 11 forms a plurality of first chambers 115 and a plurality of second ports 117, the cover plate 15 covers all the second ports 117.

[0088] The housing 11 (such as, the first housing part 113) may further include a second chamber 116 communicating with the first chamber 115. The second chamber 116 is closer to the compressor 20 than the first chamber 115. Along the insertion direction, the cross-sectional profile of the second chamber 116 is larger than the cross-sectional profiles of all the first chambers 115, and along the insertion direction, the cross-sectional profiles of all the first chambers 115 are located within the cross-sectional profile of the second chamber 116. In this way, when the connector 10 includes at least two connector terminals 16 and the compressor 20 includes at least two compressor terminals 22, when the compressor terminals 22 are connected to the connector terminals 16, all the compressor terminals 22 can pass through the second chamber 116 and then reach the corresponding first chamber 115 to realize electrical connection with the corresponding connector terminals 16. Further, the compressor 20 may include a terminal seat 23 for fixing the compressor terminals 22. The terminal seat 23 protrudes outward relative to the compressor main body. When the compressor terminals 22 are connected to the connector terminals 16, the terminal seat 23 may be located in the second chamber 116.

[0089] It can be understood that the annular groove 112 may communicate with the second chamber 116 or may not communicate with the second chamber 116. In the embodiment of the present application, the annular groove 112 does not communicate with the second chamber 116, which can avoid the deformation of the seal 12 towards the second chamber 116 when the seal 12 is squeezed, affecting the installation stability of the seal 12.

[0090] The connector 10 further includes a connecting wire 17, which is electrically connected to the connector terminal 16 and is used to realize the signal interaction between the compressor 20 and the outside when the connector terminal 16 is connected to the compressor terminal 22. Wherein, one end of the connecting wire 17 connected to the connector terminal 16 is wrapped by the second housing part 114 to improve the connection reliability between the connecting wire 17 and the connector terminal 16 and enhance the sealing performance of the connector 10. Specifically, when the second housing part 114 includes an injection molding housing part and / or a potting housing part, the second housing part 114 can directly wrap one end of the connecting wire 17 connected to the connector terminal 16 during injection molding and / or potting. If the connector 10 includes a plurality of connector terminals 16, the connecting wire 17 is electrically connected to all the plurality of connector terminals 16.

[0091] The connector terminal 16 can be any terminal, and the compressor terminal 22 can be any terminal, as long as the compressor terminal 22 can be electrically connected to the connector terminal 16.

[0092] For example, one of the connector terminal 16 and the compressor terminal 22 can be a male terminal, and the other can be a female terminal. In the embodiment of the present application, the connector terminal 16 is a female terminal, and the compressor terminal 22 is a male terminal. The connector terminal 16 is formed with a socket hole, and at least a part of the compressor terminal 22 is inserted into the socket hole and is electrically connected to the connector terminal 16. That is, when the connector terminal 16 is connected to the compressor terminal 22, at least a part of the compressor terminal 22 is surrounded by the connector terminal 16, which can improve the connection reliability between the connector terminal 16 and the compressor terminal 22.

[0093] In a second aspect, the embodiment of the present application provides a heating, ventilation and air conditioning (HVAC) system, which includes the above-mentioned connector 10 and compressor 20, and the connector 10 is electrically connected to the compressor 20. Wherein, the HVAC system can include systems for heating or cooling such as air conditioners, multi-connected units, heat pumps, etc., and the embodiment of the present application does not limit this.

[0094] The HVAC system includes a seal 12 and a connector 10. The specific structures of the seal 12 and the connector 10 refer to the above embodiments. Since the HVAC system adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.
