[0046] 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.

[0047] 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.

[0048] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the structure of a connector 10 provided in some embodiments of the present application, Figure 2 yes Figure 1 Schematic diagram of the cross-section structure in the AA direction. Figure 3 yes Figure 1 The exploded structural diagram of the connector 10 is shown. The connector 10 includes a housing 11 and a connector terminal 12 .

[0049] The housing 11 is formed with a first chamber 1117 and a first port 1111 communicating with the first chamber 1117. The connector terminal 12 is located in 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. The housing 11 is provided with a first engaging member 18 and / or a first buckling member for connecting with the compressor 20.

[0050] The connector terminal 12 is arranged in the first chamber 1117 of the housing 11, and a first port 1111 is formed on the housing 11 for the compressor terminal 21 to extend into the first chamber 1117. In this way, the connector 10 can be designed as an integrated structure. Compared with the related art in which the connector terminal is connected to the compressor terminal and then an outer cover is provided on the periphery of the connector terminal, the connection process of the connector 10 and the compressor 20 can be simplified and the assembly efficiency can be improved. Among them, the setting of the first chamber 1117 is conducive to positioning the assembly position of the connector terminal 12 in the housing 11.

[0051] The first engaging member 18 and / or the first fastening member connected to the compressor 20 are arranged on the housing 11, so that the connector 10 and the compressor 20 can be connected by snapping through the first engaging member 18 and / or the first fastening member, and the connection is convenient. For example, when the first engaging member 18 and / or the first fastening member are connected to the compressor 20, the distance between the connector 10 and the compressor 20 can be shortened by pressing the connector 10, so that the first engaging member 18 and the second fastening member 251 on the compressor 20 are matched and connected, or the first fastening member and the second engaging member on the compressor 20 are matched and connected. That is, the connection and fixation between the connector 10 and the compressor 20 can be achieved by pressing.

[0052] The housing 11 is provided with a first engaging member 18 and / or a first buckling member, and the housing 11 is provided with a first engaging member 18. In this case, the housing 11 is connected to the compressor 20 via the first engaging member 18. For example, the first engaging member 18 is connected with the second buckling member 251 on the compressor 20.

[0053] The housing 11 is provided with a first engaging member 18 and / or a first fastening member, or the housing 11 is provided with a first fastening member, in which case the housing 11 is connected to the compressor 20 via the first fastening member. For example, the first fastening member is connected with a second engaging member on the compressor 20.

[0054] The housing 11 is provided with the first engaging member 18 and / or the first fastening member, and the housing 11 may be provided with both the first engaging member 18 and the first fastening member. In this case, the housing 11 is connected to the compressor 20 through the first engaging member 18 and the first fastening member. For example, the first engaging member 18 is connected with the second fastening member 251 on the compressor 20, and the first fastening member is connected with the second engaging member on the compressor 20. The connection method between the connector 10 and the compressor 20 can be flexibly designed according to actual needs.

[0055] It should be noted that if both the first engaging member 18 and the first fastening member are provided on the housing 11, the first engaging member 18 and the first fastening member can be arranged at intervals along the circumference of the housing 11, or can be arranged at intervals along the axial direction of the housing 11, and there is no limitation on this. If the first engaging member 18 and the first fastening member are arranged at intervals along the circumference of the housing 11, when the connector 10 is connected to the compressor 20, the connection between the first engaging member 18 and the second fastening member 251 on the compressor 20, and the connection between the first fastening member and the second engaging member on the compressor 20 can be completed roughly simultaneously, which can simplify the connection steps.

[0056] The first engaging member 18 may be any device that can at least partially be locked inside another device, for example, the first engaging member 18 includes a locking protrusion. The first engaging member 18 may be provided with a chamfer so that the first engaging member 18 enters the second locking member 251 on the compressor 20. The first locking member may be any device that can at least partially lock another device, for example, the first locking member includes a bayonet.

[0057] The outer peripheral surface 115 of the housing 11 is provided with a first engaging member 18 and / or a first buckling member to facilitate the connection between the connector 10 and the compressor 20 .

[0058] See also Figure 3 If the housing 11 is provided with a first engaging member 18, the first engaging member 18 is arranged around the circumference of the housing 11. In this way, the first engaging member 18 can be connected to the compressor 20 in the entire circumference of the housing 11, so that the connector 10 and the compressor 20 can be reliably connected at various locations around the housing 11. Figure 4 , Figure 4 1 is an exploded structural diagram of the connector 10 provided in some other embodiments of the present application. If a plurality of first engaging members 18 are provided on the housing 11, the plurality of first engaging members 18 are arranged at intervals around the circumference of the housing 11. In this way, the pressing force required when the first engaging member 18 on the connector 10 is connected to the second buckling member 251 on the compressor 20 can be reduced.

[0059] If a first fastening member is provided on the housing 11, the first fastening member is arranged around the circumference of the housing 11. In this way, the first fastening member can be connected to the compressor 20 in the entire circumference of the housing 11, so that the connection between the connector 10 and the compressor 20 at various locations of the circumference of the housing 11 can be reliable. If multiple first fastening members are provided on the housing 11, the multiple first fastening members are arranged at intervals around the circumference of the housing 11. In this way, the pressing force required when the first fastening member on the connector 10 is connected to the second fastening member on the compressor 20 can be reduced.

[0060] The first engaging member 18 and the housing 11 may be detachably connected or integrally connected. The first engaging member 18 and the housing 11 may be detachably connected or integrally connected.

[0061] See also Figures 2 to 4 The housing 11 includes 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 first chamber 1117. The first housing portion 111 is also formed with a second port 1114 communicating with the first chamber 1117. The connector terminal 12 is located in the first chamber 1117 via the second port 1114. The second housing portion 112 is connected to the first housing portion 111, and the second housing portion 112 covers the second port 1114. Disassembling the housing 11 into the first housing portion 111 and the second housing portion 112 is beneficial to assembling the connector terminal 12.

[0062] In the first shell portion 111 and the second shell portion 112, the first snap-fitting component 18 and / or the first fastening component may be provided on the first shell portion 111, the first snap-fitting component 18 and / or the first fastening component may be provided on the second shell portion 112, or the first snap-fitting component 18 and / or the first fastening component may be provided on both the first shell portion 111 and the second shell portion 112.

[0063] In the embodiment of the present application, the first housing portion 111 is provided with a first engaging member 18 and / or a first fastening member. Since the first housing portion 111 is formed with a first port 1111, when the connector 10 is connected to the compressor 20, the first housing portion 111 is closer to the compressor 20 than the second housing portion 112. Therefore, by providing the first engaging member 18 and / or the first fastening member on the first housing portion 111, the connection path between the connector 10 and the compressor 20 can be shortened, and the connection is more convenient.

[0064] In an exemplary embodiment, the second shell portion 112 includes a covering portion 1122 and a wrapping portion 1123, wherein the covering portion 1122 is located on the side of the second port 1114 of the first shell portion 111, and the covering portion 1122 covers the second port 1114. The wrapping portion 1123 is arranged around the circumference of the first shell portion 111 and wraps a portion of the first shell portion 111, and the wrapping portion 1123 is connected to the covering portion 1122. In this way, the connection area between the second shell portion 112 and the first shell portion 111 can be increased, and the connection reliability between the two can be improved. At this time, the portion of the first shell portion 111 exposed to the second shell portion 112 can be provided with a first snap-fit ​​member 18 and / or a first fastener to prevent the second shell portion 112 from obstructing the first snap-fit ​​member 18 and / or the first fastener from connecting to the compressor 20. In another exemplary solution, the second housing portion 112 may also be disposed only on the side of the first housing portion 111 where the second port 1114 is located, that is, the second housing portion 112 only includes the covering portion 1122 but does not include the wrapping portion 1123. In this case, the second housing portion 112 and the first housing portion 111 may be sealed and connected by welding or the like. For example, the second housing portion 112 and the first housing portion 111 are welded and connected at the outer edge of the interface between the two to prevent impurities, moisture, etc. from entering the housing 11.

[0065] The heat resistance of the first housing portion 111 may be 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 a higher 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.

[0066] 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.

[0067] The second housing portion 112 can 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.

[0068] 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.

[0069] 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.

[0070] In summary, no matter the second shell portion 112 includes an injection molded shell portion or a glue-filled shell portion, the second shell portion 112 and the first shell portion 111 can be formed as an integral structure, which can improve the connection tightness between the second shell portion 112 and the first shell portion 111 and improve the sealing between the second shell portion 112 and the first shell portion 111, compared with the second shell portion 112 and the first shell portion 111 being independently molded and then assembled.

[0071] 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.

[0072] In order to improve the connection reliability between the second housing part 112 and the first housing part 111, one of the second housing part 112 and the first housing part 111 may be provided with a hook 1121, and the other may be provided with a slot 1115 adapted to the hook 1121, and the hook 1121 is located in the slot 1115. The second housing part 112 and the first housing part 111 can be hooked by the hook 1121 and are not easy to be separated. It can be understood that the second housing part 112 may be provided with a hook 1121, and the first housing part 111 may be provided with a slot 1115; or the second housing part 112 may be provided with a slot, and the first housing part 111 may be provided with a hook, and this is not limited.

[0073] 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 .

[0074] 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.

[0075] 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.

[0076] 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 .

[0077] 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.

[0078] If the housing 11 is formed with a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0079] 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.

[0080] See also Figures 5 and 6 , Figure 5 1 is a bottom view of a connector 10 provided in some other embodiments of the present application. Figure 6 yes Figure 5 The exploded schematic diagram of the connector 10 is shown, and the connector 10 may include a plurality of connector terminals 12, and the housing 11 is formed with a plurality of first chambers 1117, and each connector terminal 12 is located in each first chamber 1117 in a one-to-one correspondence. 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, which is not limited. Each first chamber 1117 has a second port 1114, and the second housing portion 112 and the cover cover all the second ports 1114.

[0081] In some embodiments, the first chamber 1117 may form a first port 1111. In other embodiments, the housing 11 further forms a second chamber 1118, the second chamber 1118 is in communication with the first chamber 1117, a first port 1111 is formed on a side of the second chamber 1118 away from the first chamber 1117, and the first chamber 1117 is located in the second chamber 1118 when viewed along the first port 1111. 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, and 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.

[0082] If a plurality of first chambers 1117 are formed on the housing 11, when observed along the first port 1111, 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 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 chambers 1118 and reach the corresponding first chambers 1117 to achieve electrical connection with the corresponding connector terminals 12.

[0083] The connector 10 further includes a sealing member 17, at least a portion of which is located on the side where the first port 1111 of the housing 11 is located and on the periphery of the first port 1111. The portion of the sealing member 17 located on the side where the first port 1111 of the housing 11 is located 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. It can be understood that by changing the height of the first engaging member 18 and the first fastening member on the connector 10, when the connector 10 and the compressor 20 are connected and fixed via the first engaging member 18 or the first fastening member, the compression degree of the sealing member 17 can be changed, thereby changing the sealing performance between the connector 10 and the compressor 20.

[0084] The seal 17 can be arranged on the first shell part 111. Since the heat resistance of the first shell part 111 is higher than that of the second shell part 112, even if the heat on the surface of the compressor 20 is transferred to the seal 17 and the first shell part 111, the first shell part 111 is not easily deformed, thereby being able to provide a stable support effect for the seal 17, thereby ensuring the sealing performance between the compressor 20 and the connector 10, and at the same time ensuring the smoothness of the connection between the compressor 20 and the connector 10.

[0085] See also Figure 7 , Figure 71 is a schematic diagram of the structure of the seal 17 in the connector 10 provided in some embodiments of the present application. The seal 17 has a sealing surface 173 facing away from the housing 11. The sealing surface 173 is provided with a material reduction port 1731. The material reduction port 1731 is arranged around the first port 1111. The setting of the material reduction port 1731 can reduce the mass of the seal 17 and reduce the compression amount of the seal 17. In this way, when the connector 10 is connected to the compressor 20, the rebound force generated by the seal 17 when it is squeezed will be reduced, so that the part where the seal 17 is staggered from the first engaging member 18 or the first buckling member is not easy to rebound and tilt, thereby ensuring the sealing performance of the seal 17 between the connector 10 and the compressor 20.

[0086] Furthermore, the seal 17 has two inclined surfaces 1732 that participate in forming the material reduction opening 1731. Both inclined surfaces 1732 are inclined relative to the plugging direction of the connector 10 and the compressor 20, and the distance between the two inclined surfaces 1732 gradually decreases along the direction from the opening of the material reduction opening 1731 to the bottom wall. In this way, when the seal 17 is squeezed, the inclination generated by the inclined surface 1732 can be used to make the seal 17 deform as much as possible toward the material reduction opening 1731, thereby increasing the deformation amount of the seal 17 and enhancing the sealing performance between the connector 10 and the compressor 20.

[0087] Along the direction from the opening of the material reduction port 1731 to the bottom wall, the distance between the two inclined surfaces 1732 gradually decreases. At this time, the larger distance at the opening of the material reduction port 1731 can accommodate more deformation of the seal 17, while the smaller distance at the bottom wall can constrain the deformed part of the seal 17. In addition, the deformation of the seal 17 at the two inclined surfaces 1732 is roughly the same, which can improve the flatness of the seal 17 when sealing.

[0088] The seal 17 also has a connection surface 1733 that participates in forming the material reduction port 1731. The connection surface 1733 is connected between the two inclined surfaces 1732, and the connection surface 1733 is set at an angle with the two inclined surfaces 1732. By setting the connection surface 1733, the connection surface 1733 can be used to increase the distance between the two inclined surfaces 1732 at the bottom wall of the material reduction port 1731, thereby increasing the space for accommodating the deformation of the seal 17. At this time, the space of the material reduction port 1731 is larger, and the mass of the seal 17 is smaller, so that the seal 17 has a smaller rebound force after being squeezed between the connector 10 and the compressor 20, so that when the connector 10 is only connected to the compressor 20 on one side, the seal 17 is located on the opposite side where the connector 10 and the compressor 20 are fixed, and it is less likely to be lifted.

[0089] It should be noted that the material reduction opening 1731 can be the above-mentioned one including two inclined surfaces 1732, such as a roughly V-shaped material reduction opening; it can also be the above-mentioned one including two inclined surfaces 1732 and a connecting surface 1733, such as a roughly U-shaped material reduction opening, etc. In addition, the material reduction opening 1731 can also adopt other shapes, which is not limited to this.

[0090] 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 port surface of the housing 11 where the first port 1111 is provided. 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 adhesives or the like to prevent the seal 17 from falling off.

[0091] In another exemplary embodiment, see Figure 2 The port surface of the first port 1111 of the shell 11 may be provided with an annular groove 1113, the annular groove 1113 is arranged around the first port 1111, 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 shell 11, thereby speeding up the assembly speed between the seal 17 and the shell 11, and on the other hand, can restrain the seal 17, thereby accommodating the deformation of the seal 17 caused by extrusion and preventing it from moving easily.

[0092] 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 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.

[0093] It is understandable that the annular groove 1113 may be connected to the first port 1111 or may not be connected to the first port 1111. In the embodiment of the present application, the annular groove 1113 is not connected to the first port 1111, which can prevent the seal 17 from deforming toward the first port 1111 when it is squeezed and deformed, thereby affecting the installation stability of the seal 17. It should be noted that the seal 17 can be installed in the annular groove 1113 by snapping, or by bonding, etc., and this is not limited.

[0094] 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.

[0095] The seal 17 may not belong to the connector 10 , but when the connector 10 is connected to the compressor 20 , the seal 17 is directly provided between the connector 10 and the compressor 20 , and this is not limited.

[0096] It should be noted that if the first engaging member 18 is provided on the housing 11, the first engaging member 18 can be connected to the sealing member 17 as a whole to simplify the assembly process. Furthermore, the first engaging member 18 can be elastic, and the first engaging member 18 can have a sealing effect while being connected to the compressor 20, thereby improving the sealing performance between the connector 10 and the compressor 20.
