[0047] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0048] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0049] First, see Figures 1 to 5 The present invention provides a connector 1 including a housing 10 and a connector terminal 20. The housing 10 has a mounting channel 11, and the mounting channel 11 has a first port 1111 and a second port 1121. The housing 10 is elastic, and the connector terminal 20 extends into the mounting channel 11 through the first port 1111 and is located in the mounting channel 11. The connector terminal 20 is configured to electrically connect to the compressor terminal 3, which extends into the mounting channel 11 through the second port 1121.

[0050] In the embodiment of the present application, the housing 10 of the connector 1 is designed to be elastic as a whole. In this way, the connector terminal 20 can be extended into the mounting channel 11 of the housing 10 through the first port 1111 of the housing 10 to realize the assembly between the connector terminal 20 and the housing 10. That is, in the embodiment of the present application, the connector terminal 20 and the housing 10 can be independently molded and then assembled. Compared with the related art in which the connector terminal and the housing are integrally molded through injection molding or other processes, it is convenient for the connector terminal 20 and the housing 10 to be disassembled, replaced, etc. When the connector 1 is damaged, compared with replacing the entire connector, only the damaged connector terminal 20 or the housing 10 can be replaced, thereby reducing maintenance costs. In addition, the housing 10 is elastic as a whole. When the compressor terminal 3 and the connector terminal 20 are plugged into each other, the housing 10 can also undergo a certain deformation to adapt to the tolerance of the compressor terminal 3, thereby reducing the precision requirements of the connector 1 of the embodiment of the present application and reducing the production cost of the connector 1.

[0051] It should be noted that, since the housing 10 is elastic, to prevent deformation of the housing 10 that could cause misalignment between the connector terminals 20 and the compressor terminals 3, when the connector 1 and the compressor terminals 3 are mated, the housing 10 can be squeezed to grip the connector terminals 20 to facilitate mating. That is, when the connector 1 and the compressor terminals 3 are mated, force can be applied directly to the connector terminals 20 to control their orientation.

[0052] The housing 10 can be made of any elastic material, as long as it can deform to a certain extent when assembled with the connector terminal 20, so that the connector terminal 20 can extend into the mounting channel 11 through the first port 1111 of the housing 10 and be positioned appropriately within the mounting channel 11, and can be electrically connected to the compressor terminal 3 extending through the second port 1121. In the embodiment of the present application, the housing 10 is made of silicone rubber, which is inexpensive and can meet the elastic requirements of the housing 10.

[0053] The mounting channel 11 can be either a straight channel or a curved channel. A straight channel can simplify the installation of the connector terminal 20 and speed up the assembly between the connector terminal 20 and the housing 10. A curved channel, on the other hand, can increase the assembly complexity of the connector terminal 20 within the mounting channel 11 and make it easier to move the connector terminal 20 within the mounting channel 11. This prevents the connector terminal 20 from moving significantly after being installed within the mounting channel 11, thereby ensuring convenient electrical connection between the connector terminal 20 and the compressor terminal 3.

[0054] In the embodiments of this application, see Figure 4 and Figure 5 The mounting channel 11 is a curved channel. Specifically, the mounting channel 11 includes a first channel 111 and a second channel 112. The first channel 111 has a first port 1111. The second channel 112 communicates with the end of the first channel 111 facing away from the first port 1111. The second channel 112 curves relative to the first channel 111 and has a second port 1121 at the end facing away from the first channel 111. The connector terminal 20 is located in the second channel 112. Specifically, the connector terminal 20 is disposed in the second channel 112, which curves relative to the first channel 111. Once located in the second channel 112, the connector terminal 20 is less likely to move from the second channel 112 into the first channel 111. This improves the stability of the connector terminal 20 within the second channel 112 and facilitates the electrical connection between the connector terminal 20 and the compressor terminal 3.

[0055] It should be noted that the first channel 111 can be a straight channel or a curved channel; the second channel 112 can be a straight channel or a curved channel. In the embodiment of the present application, the first channel 111 can be flexibly designed to be a straight channel or a curved channel in combination with the miniaturization requirements of the connector 1, etc., which will be described in more detail below, and the second channel 112 is a straight channel. Among them, the second channel 112 is a straight channel. On the one hand, it is convenient for the connector terminal 20 to enter the second channel 112. On the other hand, it is also convenient for the compressor terminal 3 to be inserted into the second channel 112 in a roughly straight direction, and it is not easy to deviate, so as to facilitate the alignment and electrical connection of the compressor terminal 3 and the connector terminal 10.

[0056] It is understood that to facilitate movement of the connector terminals 20 within the mounting channel 11 and installation at appropriate positions within the mounting channel 11, the cross-sectional area of the mounting channel 11 along the extension direction of the mounting channel 11 may be greater than or equal to the cross-sectional area of the connector terminals 20. Furthermore, to reduce the risk of the connector terminals 20 moving again after being installed at appropriate positions within the mounting channel 11 and to achieve miniaturization of the connector 1, the difference between the cross-sectional areas of the mounting channel 11 and the connector terminals 20 along the extension direction of the mounting channel 11 should not be too large.

[0057] In the embodiment of the present application, along the extension direction of the mounting channel 11, the cross-sectional profile area of the mounting channel 11 is a1, and the cross-sectional profile area of the connector terminal 20 is a2. The connector 1 can satisfy: a2≤a1≤2a2. By reasonably limiting the cross-sectional profile area of the mounting channel 11 and the cross-sectional profile area of the connector terminal 20 along the extension direction of the mounting channel 11, the connector 1 can take into account the advantages of ease of assembly of the connector terminal 20 in the mounting channel 11, assembly stability of the connector terminal 20 in the mounting channel 11, miniaturization, etc. Optionally, a1 can be equal to a2, 1.25a2, 1.5a2, 1.75a2, 2a2, etc., and the embodiment of the present application does not limit this.

[0058] It should be noted that, along the extension direction of the mounting channel 11, the cross-sectional profile of the mounting channel 11 can be roughly circular, polygonal, etc., and there is no limitation on this. Along the extension direction of the mounting channel 11, the cross-sectional profile area of the mounting channel 11 can remain unchanged, or can be gradually changed, etc., and there is no limitation on this. Among them, the gradual change can be: along the extension direction of the mounting channel 11, from the first port 1111 to the second port 1121, the cross-sectional profile area of the mounting channel 11 gradually becomes smaller, or the cross-sectional profile area of the mounting channel 11 first remains unchanged and then gradually decreases and finally remains unchanged, etc. The embodiment of the present application does not limit the specific shape of the mounting channel 11. Among them, if along the extension direction of the mounting channel 11, from the first port 1111 to the second port 1121, the cross-sectional profile area of the mounting channel 11 has a tendency to become smaller, the assembly stability of the connector terminal 20 in the mounting channel 11 can be improved.

[0059] It should be noted that the cross-sectional area of mounting channel 11 along its extension direction may be defined as the area enclosed by the corresponding projected outer contour of the mounting channel 11 at each location within the plane in which the cross-section is located. The cross-sectional area of connector terminal 20 may be defined as the area enclosed by the projected outer contour of connector terminal 20 within a second plane, where the second plane may be perpendicular to the insertion direction of connector terminal 20 and located to one side of connector terminal 20.

[0060] The plugging direction of the connector terminal 20 refers to the relative movement direction of the connector terminal 20 and the compressor terminal 3 when the two are plugged together. If the connector terminal 20 has a plugging hole and the compressor terminal 3 is used to be plugged into the plugging hole, the plugging direction can be parallel to the extension direction of the plugging hole.

[0061] If the cross-sectional area of the mounting channel 11 is larger than the cross-sectional area of the connector terminal 20 along the extension direction of the mounting channel 11 , effective electrical connection between the compressor terminal 3 and the connector terminal 20 with tolerance can also be ensured.

[0062] Due to factors such as manufacturing errors, the compressor terminals 3 of the compressor 2 inevitably have tolerances, such as the thickness of the compressor terminals 3, the inclination of the compressor terminals 3, the spacing between two adjacent compressor terminals 3, etc., and the cross-sectional profile area of the mounting channel 11 is designed to be larger than the cross-sectional profile area of the connector terminals 20 along the extension direction of the mounting channel 11. This allows the compressor terminals 3 to be inserted into the mounting channel 11 to contact the connector terminals 20, thereby pushing the connector terminals 20 toward the remaining space in the mounting channel 11 to accommodate the tolerances of the compressor terminals 3. Furthermore, the connector terminals 20 are not fixed in the mounting channel 11. When the compressor terminals 3 and the connector terminals 20 are plugged into each other, the connector terminals 20 can move to a certain extent in the mounting channel 11 along the extension direction thereof to avoid damage to the compressor terminals 3 and the connector terminals 20 due to forced insertion. Of course, the elastic housing 10 can also deform to avoid damage to the compressor terminals 3 and the connector terminals 20 due to forced insertion.

[0063] See Figure 4 and Figure 6 The connector 1 further includes a first sealing flange 15, which is disposed around the second port 1121. The first sealing flange 15 is connected to the housing 10 and protrudes from the housing 10. The first sealing flange 15 is configured to surround the compressor terminal 3. The first sealing flange 15 can seal the compressor terminal 3. The first sealing flange 15 can be elastic, allowing the first sealing flange 15 to be stretched by the compressor terminal 3 and only cover the compressor terminal 3, thereby achieving a better sealing effect.

[0064] The first sealing flange 15 and the housing 10 can be integrally formed. This simplifies the assembly process and provides a more reliable connection than if the first sealing flange 15 and the housing 10 were formed separately and then assembled. Of course, the housing 10 and the first sealing flange 15 can also be formed separately and then assembled, allowing for flexible design based on actual usage requirements.

[0065] See Figure 2 、 Figure 4 and Figure 5 Connector 1 includes a plurality of connector terminals 20, and housing 10 includes a plurality of mounting channels 11 equal in number to the number of connector terminals 20. Each connector terminal 20 is provided in a one-to-one correspondence with each mounting channel 11. For example, connector 1 includes two connector terminals 20, and housing 10 is formed with two mounting channels 11; alternatively, connector 1 includes three connector terminals 20, and housing 10 is formed with three mounting channels 11, and so on, without limitation. By providing a mounting channel 11 corresponding to each connector terminal 20, mutual isolation and insulation between the connector terminals 20 can be achieved.

[0066] Among the multiple mounting channels 11, the central axes of at least two first channels 111 can be approximately located in the first plane. Designing the central axes of at least two first channels 111 to be approximately located in the first plane can reduce the dimension of the connector 1 perpendicular to the first plane, compared to designing the central axes of the first channels 111 to be located in different planes, making the connector 1 more compact.

[0067] It should be noted that, based on usage requirements, etc., the central axes of some of the first channels 111 in the multiple mounting channels 11 can be designed to be approximately located in the first plane, or the central axes of all the first channels 111 in the multiple mounting channels 11 can be designed to be approximately located in the first plane. In the embodiment of the present application, the connector 1 includes three connector terminals 20, and the housing 10 includes three mounting channels 11. In the three mounting channels 11, the central axes of all the first channels 111 are approximately located in the first plane.

[0068] Furthermore, when the central axes of at least two first channels 111 are approximately located in the first plane, at least one first channel 111 having its central axis located in the first plane includes a first sub-channel 1112 and a second sub-channel 1113 that are curved toward each other, and the first sub-channel 1112 is connected to the second sub-channel 1113. This allows for a more compact arrangement of the first channels 111 having their central axes approximately located in the first plane, thereby reducing the cross-sectional area of the connector 1 in the first plane.

[0069] It should be noted that each first channel 111, whose central axis is approximately located in the first plane, can be designed to be a straight channel or a curved channel including a first sub-channel 1112 and a second sub-channel 1113, based on usage requirements, etc. In the embodiment of the present application, in the three installation channels 11, the central axes of all first channels 111 are approximately located in the first plane, and among the three first channels 111, one first channel 111 is a substantially straight channel, while the remaining two first channels 111 are curved channels including a first sub-channel 1112 and a second sub-channel 1113, and both curved channels are curved toward the straight channel, so that the arrangement of each first channel 111 is more compact.

[0070] Optionally, at least two first ports 1111 in the plurality of mounting channels 11 are connected, so that the first port 1111 has a larger diameter, which facilitates the connector terminal 20 to enter the housing 10. In the embodiment of the present application, all first ports 1111 in the plurality of mounting channels 11 are connected to each other.

[0071] Optionally, the central axes of all second channels 112 in the plurality of mounting channels 11 are parallel, so that the connector terminals 20 disposed within each second channel 112 are arranged in substantially parallel directions, thereby facilitating alignment and insertion of the compressor terminals 3 with the connector terminals 20. It should be noted that when there are multiple connector terminals 20, the number of compressor terminals 3 is equal to the number of connector terminals 20, and each compressor terminal 3 is used to electrically connect to one connector terminal 20.

[0072] Optionally, in the plurality of mounting channels 11, all first ports 1111 are located on the same side of the housing 10, and all second ports 1121 are located on the other side of the housing 10. That is, the first ports 1111 for inserting the connector terminals 20 and the second ports 1121 for inserting the compressor terminals 3 are located on different sides of the housing 10. This can reduce the risk of the connection wires 30 connected to the connector terminals 20 at the first ports 1111 being obstructed in the insertion of the compressor terminals 3 into the connector terminals 20.

[0073] It is understandable that, along the plugging direction of the connector terminal 20 and the compressor terminal 3, the cross-section of the housing 10 can be roughly polygonal, circular, etc. Wherein, if the cross-section of the housing 10 along the plugging direction is roughly polygonal, the housing 10 has sides corresponding to the sides of the polygon, and two end sides opposite to each other along the plugging direction, all of the above-mentioned first ports 1111 can be located on any one of the multiple sides or the two end sides, and all of the above-mentioned second ports 1121 can be located on any other one of the multiple sides or the two end sides. Wherein, if the cross-section of the housing 10 along the plugging direction is roughly circular, the housing has a circular wall side corresponding to the circle, and two end sides opposite to each other along the plugging direction, all of the above-mentioned first ports 1111 can be located on one circular wall side or any one of the two end sides, and all of the above-mentioned second ports 1121 can be located on one circular wall side or any one of the two end sides, etc., and this embodiment of the present application does not limit this.

[0074] In the embodiments of this application, see Figure 4 The housing 10 has a side wall 13 and a bottom wall 14. The first port 1111 is provided on the side wall 13, and the second port 1121 is provided on the bottom wall 14. The bottom wall 14 may be at least one of two opposite end sides along the plugging direction.

[0075] See also Figure 4 and Figure 6The connector 1 further includes a second sealing flange 16, which is disposed on the periphery of the bottom wall 14. The second sealing flange 16 is connected to the housing 10 and protrudes from the housing 10. The side of the second sealing flange 16 facing away from the bottom wall 14 is used to abut the compressor 2. The second sealing flange 16 can ensure a tight seal between the connector 1 and the compressor 2 when the two are connected. The second sealing flange 16 can be elastic, so that the second sealing flange 16 can be squeezed and deformed by the compressor 2 to achieve a seal between the connector 1 and the compressor 2, achieving an excellent sealing effect.

[0076] The second sealing flange 16 and the housing 10 can be integrally formed, which simplifies the assembly process and provides a more reliable connection compared to separately forming the second sealing flange 16 and the housing 10 and then assembling them. Of course, the housing 10 and the second sealing flange 16 can also be separately formed and then assembled, allowing for flexible design based on actual usage requirements.

[0077] It should be noted that, see Figure 6 The compressor 2 may further include a terminal block 4 for securing the compressor terminals 3. The terminal block 4 protrudes relative to the compressor body. When the compressor terminals 3 are connected to the connector terminals 20, the terminal block 4 may be located within the area enclosed by the second sealing flange 16. Furthermore, the terminal block 4 may contact the second sealing flange 16 to further enhance the sealing between the connector 1 and the compressor 2.

[0078] See Figures 4 to 6 , the connector 1 also includes a connecting wire 30, a portion of the connecting wire 30 extends into the installation channel 11 through the first port 1111 and is located in the first channel 111, and the connecting wire 30 is electrically connected to the connector terminal 20. When the connector terminal 20 is electrically connected to the compressor terminal 3, the connecting wire 30 can realize the electrical connection between the compressor 2 and the outside world. It should be noted that the connector 1 includes a plurality of connector terminals 20, and the connector 1 includes connecting wires 30 equal in number to the connector terminals 20, and each connector terminal 20 is connected to each connecting wire 30 in a one-to-one correspondence. Among them, the connecting wire 30 can be a soft wire, which can be twisted and deformed, and will not affect the assembly of the connector terminal 20 and the housing 10.

[0079] See Figures 4 to 6The connector 1 further includes a third sealing flange 17, which is disposed on the periphery of the first port 1111. The third sealing flange 17 is connected to the housing 10 and protrudes from the housing 10. The third sealing flange 17 is configured to surround the periphery of the connecting line 30 and be sealed therewith. The third sealing flange 17 can be elastic, and the third sealing flange 17 and the housing 10 can be integrally formed. Compared to forming the third sealing flange 17 and the housing 10 separately and then assembling them, this simplifies the assembly process and provides a more reliable connection between the two. Of course, the housing 10 and the third sealing flange 17 can also be formed separately and then assembled, allowing for flexible design based on actual usage requirements.

[0080] It should be noted that when the housing 10 includes multiple mounting channels 11, if the first ports 1111 of the multiple mounting channels 11 are independent of each other, the number of third sealing flanges 17 can be equal to the number of first ports 1111, and each third sealing flange 17 is provided corresponding to a first port 1111, and each third sealing flange 17 is used to seal the connection line 30 in the corresponding mounting channel 11. If the first ports 1111 of multiple mounting channels 11 are connected, the number of third sealing flanges 17 can be one, and one third sealing flange 17 is provided around the periphery of all first ports 1111, and the one third sealing flange 17 is sealed with the connection line 30. In the embodiment of the present application, the housing 10 includes a third sealing flange 17 provided around the periphery of all first ports 1111 to simplify the sealing process between the third sealing flange 17 and the connection line 30. The multiple connection lines 30 can be wrapped together with a coating material.

[0081] In one exemplary embodiment, the connector 1 further includes a cable tie (not shown), and the third sealing flange 17 and the connecting wire 30 can be sealed by the cable tie. For example, the cable tie is wrapped around the periphery of the third sealing flange 17 and tightens the third sealing flange 17 and the connecting wire 30. In another exemplary embodiment, the third sealing flange 17 and the connecting wire 30 are sealed with a sealant. In yet another exemplary embodiment, the third sealing flange 17 and the connecting wire 30 can be tightened with a cable tie and then sealed with a sealant.

[0082] It should be noted that, since the connector 1 is located inside the HVAC system during use, such as when used in a HVAC system, and is not directly visible to the user, the cable tie on the connector 1 is not visible to the user.

[0083] Second, see Figure 6 The embodiment of the present application provides a HVAC system, which includes the above-mentioned connector 1 and a compressor 2 connected to the connector 1. The HVAC system may include an air conditioner, a multi-split unit, a heat pump, or other systems for heating or cooling, which is not limited in the embodiment of the present application.

[0084] The HVAC system includes a connector 1, and the specific structure of the connector 1 refers to the above embodiment. Since the HVAC system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0085] In a third aspect, an embodiment of the present application provides a method for assembling a connector 1, wherein the connector 1 is the connector 1 described above, and the assembly method includes:

[0086] Step S02 , providing a housing 10 and a connector terminal 20 ; wherein the housing 10 has a mounting channel 11 , the mounting channel 11 has a first port 1111 and a second port 1121 , and the housing 10 is elastic.

[0087] In step S04 , the connector terminal 20 is inserted into the installation channel 11 through the first port 1111 and is located in the installation channel 11 .

[0088] In the embodiment of the present application, the housing 10 of the connector 1 is designed to be elastic as a whole. In this way, the connector terminal 20 can be extended into the mounting channel 11 of the housing 10 through the first port 1111 of the housing 10 to realize the assembly between the connector terminal 20 and the housing 10. That is, in the embodiment of the present application, the connector terminal 20 and the housing 10 can be independently molded and then assembled. Compared with the related art in which the connector terminal and the housing are integrally molded through injection molding or other processes, it is convenient for the connector terminal 20 and the housing 10 to be disassembled, replaced, etc. When the connector 1 is damaged, compared with replacing the entire connector, only the damaged connector terminal 20 or the housing 10 can be replaced, thereby reducing maintenance costs. In addition, the housing 10 is elastic as a whole. When the compressor terminal 3 and the connector terminal 20 are plugged into each other, the housing 10 can also undergo a certain deformation to adapt to the tolerance of the compressor terminal 3, thereby reducing the precision requirements of the connector 1 of the embodiment of the present application and reducing the production cost of the connector 1.

[0089] It should be noted that, since the housing 10 is elastic, to prevent deformation of the housing 10 that could cause misalignment between the connector terminals 20 and the compressor terminals 3, when the connector 1 and the compressor terminals 3 are mated, the housing 10 can be squeezed to grip the connector terminals 20 to facilitate mating. That is, when the connector 1 and the compressor terminals 3 are mated, force can be applied directly to the connector terminals 20 to control their orientation.

[0090] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to at least two, for example, two, three, four, etc. "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0091] The above disclosure is only a preferred embodiment of the present application, and certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
