DETAILED DESCRIPTION

[0117] 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.

[0118] 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.

[0119] In the first aspect, embodiment 1, referring to Figures 1 to 5 , the present embodiment provides a connector 1 comprising a housing 11 and a connector terminal 12. The housing 11 has a first chamber 1117, which includes a first port 1111 and a second port 1114. The housing 11 is elastic, and the connector terminal 12 extends into the first chamber 1117 via the first port 1111 and is located within the first chamber 1117. The connector terminal 12 is configured to electrically connect to a compressor terminal 21, which extends into the first chamber 1117 via the second port 1114.

[0120] In the embodiment of the present application, the housing 11 of the connector 1 is designed to be elastic as a whole. In this way, the connector terminal 12 can extend from the first port 1111 of the housing 11 into the first chamber 1117 thereof to achieve assembly between the connector terminal 12 and the housing 11. That is, in the embodiment of the present application, the connector terminal 12 and the housing 11 can be independently molded and then assembled. Compared with the related art in which the connector terminal and the housing are integrally molded through a process such as injection molding, this facilitates the disassembly, assembly, and replacement of the connector terminal 12 and the housing 11. When the connector 1 is damaged, compared with replacing the entire connector, only the damaged connector terminal 12 or the housing 11 can be replaced, thereby reducing maintenance costs. In addition, the housing 11 is elastic as a whole. When the compressor terminal 21 and the connector terminal 12 are plugged into each other, the housing 11 can also undergo a certain deformation to adapt to the tolerance of the compressor terminal 21, thereby reducing the precision requirements of the connector 1 in the embodiment of the present application and reducing the manufacturing cost of the connector 1.

[0121] It should be noted that, since the housing 11 is elastic, to prevent deformation of the housing 11 that could cause misalignment between the connector terminals 12 and the compressor terminals 21, when the connector 1 and the compressor terminals 21 are mated, the housing 11 can be squeezed to grip the connector terminals 12 to achieve mating between the connector terminals 12 and the compressor terminals 21. In other words, when the connector 1 and the compressor terminals 21 are mated, force can be applied directly to the connector terminals 12 to control the direction of the connector terminals 12.

[0122] The housing 11 can be made of any elastic material, as long as it can deform to a certain extent when assembled with the connector terminal 12, so that the connector terminal 12 can extend into the first cavity 1117 through the first port 1111 of the housing 11 and be positioned appropriately within the first cavity 1117, thereby electrically connecting to the compressor terminal 21 extending through the second port 1114. In the embodiment of the present application, the housing 11 is made of silicone rubber, which is inexpensive and can meet the elasticity requirements of the housing 11.

[0123] The first chamber 1117 can be a straight channel or a curved channel. A straight channel can simplify the installation of the connector terminal 12 and speed up the assembly between the connector terminal 12 and the housing 11. A curved channel, on the other hand, can increase the assembly complexity of the connector terminal 12 within the first chamber 1117 and make it easier to move the connector terminal 12 within the first chamber 1117. This prevents the connector terminal 12 from moving significantly after being installed within the first chamber 1117, thereby ensuring convenient electrical connection between the connector terminal 12 and the compressor terminal 21.

[0124] In the embodiment of the present application, referring to Figures 4 and 5 , first chamber 1117 is a curved channel. Specifically, first chamber 1117 includes a first channel 101 and a second channel 102. First channel 101 has a first port 1111. Second channel 102 communicates with the end of first channel 101 facing away from first port 1111. Second channel 102 curves relative to first channel 101 and has a second port 1114 at the end facing away from first channel 101. Connector terminal 12 is located in second channel 102. Specifically, connector terminal 12 is disposed in second channel 102, which curves relative to first channel 101. Once located in second channel 102, connector terminal 12 is less likely to move from second channel 102 into first channel 101, thereby enhancing its stable installation within second channel 102 and improving the electrical connection between connector terminal 12 and compressor terminal 21.

[0125] It should be noted that the first channel 101 can be a straight channel or a curved channel; the second channel 102 can be a straight channel or a curved channel. In the embodiment of the present application, the first channel 101 can be flexibly designed to be a straight channel or a curved channel in combination with the requirements of miniaturization of the connector 1, etc., which will be explained in more detail below, and the second channel 102 is a straight channel. Among them, the second channel 102 is a straight channel. On the one hand, it is convenient for the connector terminal 12 to enter the second channel 102. On the other hand, it is also convenient for the compressor terminal 21 to be inserted into the second channel 102. The compressor terminal 21 is inserted into the second channel 102 roughly in a straight direction, and is not easily offset, so as to facilitate the alignment and electrical connection of the compressor terminal 21 and the connector terminal 10.

[0126] It is understood that to facilitate movement of the connector terminal 12 within the first cavity 1117 and installation at a suitable position within the first cavity 1117, the cross-sectional area of ​​the first cavity 1117 along the extension direction of the first cavity 1117 may be greater than or equal to the cross-sectional area of ​​the connector terminal 12. Furthermore, to reduce the risk of the connector terminal 12 moving again after being installed at a suitable position within the first cavity 1117 and to achieve miniaturization of the connector 1, the difference between the cross-sectional area of ​​the first cavity 1117 and the cross-sectional area of ​​the connector terminal 12 along the extension direction of the first cavity 1117 should not be too large.

[0127] In the embodiment of the present application, along the extension direction of the first cavity 1117, the cross-sectional profile area of ​​the first cavity 1117 is a1, and the cross-sectional profile area of ​​the connector terminal 12 is a2. The connector 1 can satisfy the following relationship: a2≤a1≤2a2. By reasonably limiting the cross-sectional profile area of ​​the first cavity 1117 and the cross-sectional profile area of ​​the connector terminal 12 along the extension direction of the first cavity 1117, the connector 1 can take into account the advantages of ease of assembly of the connector terminal 12 in the first cavity 1117, assembly stability of the connector terminal 12 in the first cavity 1117, miniaturization, etc. Optionally, a1 can be equal to a2, 1.25a2, 1.5a2, 1.75a2, 2a2, etc., which is not limited in the embodiment of the present application.

[0128] It should be noted that, along the extension direction of the first cavity 1117, the cross-sectional profile of the first cavity 1117 can be generally circular, polygonal, etc., without limitation. Along the extension direction of the first cavity 1117, the cross-sectional profile area of ​​the first cavity 1117 can remain constant or change gradually, without limitation. The gradual change can include: along the extension direction of the first cavity 1117, from the first port 1111 to the second port 1114, the cross-sectional profile area of ​​the first cavity 1117 gradually decreases; or, the cross-sectional profile area of ​​the first cavity 1117 initially remains constant, then gradually decreases, and finally remains constant, etc. The specific shape of the first cavity 1117 is not limited in this embodiment of the present application. If the cross-sectional profile area of ​​the first cavity 1117 decreases along the extension direction of the first cavity 1117, from the first port 1111 to the second port 1114, the assembly stability of the connector terminal 12 within the first cavity 1117 can be improved.

[0129] It should be noted that the cross-sectional area of ​​first cavity 1117 along its extension direction may be defined as the area enclosed by the corresponding projected outer contour of the cross section of first cavity 1117 at various locations within the plane. The cross-sectional area of ​​connector terminal 12 may be defined as the area enclosed by the projected outer contour of connector terminal 12 within a second plane, where the second plane may be perpendicular to the insertion direction of connector terminal 12 and located to one side of connector terminal 12.

[0130] The plugging direction of the connector terminal 12 refers to the relative movement direction of the connector terminal 12 and the compressor terminal 21 when the two are plugged together. If the connector terminal 12 has a plugging hole and the compressor terminal 21 is used to be plugged into the plugging hole, the plugging direction can be parallel to the extension direction of the plugging hole.

[0131] If the cross-sectional contour area of ​​the first chamber 1117 is larger than the cross-sectional contour area of ​​the connector terminal 12 along the extension direction of the first chamber 1117 , effective electrical connection between the compressor terminal 21 and the connector terminal 12 with tolerance can also be ensured.

[0132] Due to factors such as manufacturing errors, the compressor terminals 21 of the compressor 20 inevitably have tolerances, such as the thickness of the compressor terminals 21, the inclination of the compressor terminals 21, and the spacing between adjacent compressor terminals 21. The cross-sectional area of ​​the first cavity 1117 along the extension direction of the first cavity 1117 is designed to be larger than the cross-sectional area of ​​the connector terminal 12. This allows the compressor terminal 21 to move toward the remaining space in the first cavity 1117 when inserted into the first cavity 1117 and into contact with the connector terminal 12, thereby accommodating the tolerances of the compressor terminal 21. Furthermore, the connector terminal 12 is not fixed within the first cavity 1117. When the compressor terminal 21 and the connector terminal 12 are mated, the connector terminal 12 can move within the first cavity 1117 along its extension direction to prevent damage to the compressor terminal 21 and the connector terminal 12 from being forced into the first cavity 1117. Furthermore, the elastic housing 11 can also deform to prevent damage to the compressor terminal 21 and the connector terminal 12 from being forced into the first cavity 1117.

[0133] Referring to Figures 4 and 6 , the connector 1 further includes a first sealing flange 105 , which is disposed around the second port 1114 . The first sealing flange 105 is connected to the housing 11 and protrudes from the housing 11 . The first sealing flange 105 is configured to surround the compressor terminal 21 . The first sealing flange 105 can seal the compressor terminal 21 . The first sealing flange 105 can be elastic, allowing it to be stretched by the compressor terminal 21 and only cover the compressor terminal 21, achieving a better sealing effect.

[0134] The first sealing flange 105 and the housing 11 can be integrally formed, which simplifies the assembly process and provides a more reliable connection compared to separately forming the first sealing flange 105 and the housing 11 and then assembling them. Of course, the housing 11 and the first sealing flange 105 can also be separately formed and then assembled, allowing for flexible design based on actual usage requirements.

[0135] Referring to Figures 2, 4, and 5, connector 1 includes a plurality of connector terminals 12, and housing 11 includes a plurality of first chambers 1117, equal in number to the number of connector terminals 12. Each connector terminal 12 is provided in a one-to-one correspondence with each first chamber 1117. For example, connector 1 may include two connector terminals 12, and housing 11 may form two first chambers 1117; alternatively, connector 1 may include three connector terminals 12, and housing 11 may form three first chambers 1117, and so on, without limitation. By providing a first chamber 1117 corresponding to each connector terminal 12, mutual isolation and insulation between the connector terminals 12 can be achieved.

[0136] In the plurality of first chambers 1117, the central axes of at least two first channels 101 can be approximately located in the first plane. Designing the central axes of at least two first channels 101 to be approximately located in the first plane can reduce the dimensions of the connector 1 perpendicular to the first plane, compared to designing the central axes of the first channels 101 to be located in different planes, making the connector 1 more compact.

[0137] It should be noted that, based on usage requirements, etc., the central axes of some of the first channels 101 in the multiple first cavities 1117 can be designed to be approximately located in the first plane, or the central axes of all the first channels 101 in the multiple first cavities 1117 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 12, and the housing 11 includes three first cavities 1117. In the three first cavities 1117, the central axes of all the first channels 101 are approximately located in the first plane.

[0138] Furthermore, when the central axes of at least two first channels 101 are approximately located in the first plane, at least one first channel 101 having its central axis located in the first plane includes a first sub-channel 1012 and a second sub-channel 1013 that are curved toward each other, and the first sub-channel 1012 is connected to the second sub-channel 1013. This allows the arrangement of the first channels 101 having their central axes approximately located in the first plane to be more compact, thereby reducing the cross-sectional area of ​​the connector 1 in the first plane.

[0139] It should be noted that each first channel 101, 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 1012 and a second sub-channel 1013, based on usage requirements, etc. In the embodiment of the present application, the central axes of all the first channels 101 in the three first chambers 1117 are approximately located in the first plane, and among the three first channels 101, one first channel 101 is a substantially straight channel, while the remaining two first channels 101 are curved channels including a first sub-channel 1012 and a second sub-channel 1013, and both curved channels are curved toward the straight channel, so that the arrangement of each first channel 101 is more compact.

[0140] Optionally, at least two first ports 1111 in the plurality of first chambers 1117 are connected, so that the first port 1111 has a larger diameter, which facilitates the connector terminal 12 to enter the housing 11. In the embodiment of the present application, all first ports 1111 in the plurality of first chambers 1117 are connected to each other.

[0141] Optionally, the central axes of all second channels 102 in the plurality of first chambers 1117 are parallel, so that the connector terminals 12 disposed within the second channels 102 are arranged in substantially parallel directions, thereby facilitating alignment and insertion of the compressor terminals 21 with the connector terminals 12. It should be noted that when there are multiple connector terminals 12, the number of compressor terminals 21 is equal to the number of connector terminals 12, and each compressor terminal 21 is configured to electrically connect to one connector terminal 12.

[0142] Optionally, in the plurality of first chambers 1117, all first ports 1111 are located on the same side of the housing 11, and all second ports 1114 are located on the other side of the housing 11. That is, the first ports 1111 for inserting the connector terminals 12 and the second ports 1114 for inserting the compressor terminals 21 are located on different sides of the housing 11. This can reduce the risk of the connection wires 15 connected to the connector terminals 12 at the first ports 1111 being obstructed in the insertion of the compressor terminals 21 into the connector terminals 12.

[0143] It is understandable that, along the plugging direction of the connector terminal 12 and the compressor terminal 21, the cross-section of the housing 11 can be roughly polygonal, circular, etc. Wherein, if the cross-section of the housing 11 along the plugging direction is roughly polygonal, the housing 11 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 1114 can be located on any other one of the multiple sides or the two end sides. Wherein, if the cross-section of the housing 11 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 1114 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.

[0144] 4 , the housing 11 has a side wall 103 and a bottom wall 104. The first port 1111 is provided on the side wall 103, and the second port 1114 is provided on the bottom wall 104. The bottom wall 104 may be at least one of two opposite end sides along the plugging direction.

[0145] Referring to Figures 4 and 6 , connector 1 also includes a second sealing flange 106, which is disposed on the periphery of bottom wall 104. Second sealing flange 106 is connected to housing 11 and protrudes from housing 11. The side of second sealing flange 106 facing away from bottom wall 104 is configured to abut compressor 20. Second sealing flange 106 ensures a seal between connector 1 and compressor 20 when connected. Second sealing flange 106 can be elastic, allowing compression and deformation by compressor 20 to achieve a seal between connector 1 and compressor 20, resulting in a better sealing effect.

[0146] The second sealing flange 106 and the housing 11 can be integrally formed, which simplifies the assembly process and provides a more reliable connection compared to separately forming the second sealing flange 106 and the housing 11 and then assembling them. Of course, the housing 11 and the second sealing flange 106 can also be separately formed and then assembled, allowing for flexible design based on actual usage requirements.

[0147] It should be noted that, referring to FIG6 , the compressor 20 may further include a terminal block 23 for securing the compressor terminal 21. The terminal block 23 protrudes relative to the compressor body. When the compressor terminal 21 is connected to the connector terminal 12, the terminal block 23 may be located within the area enclosed by the second sealing flange 106. Furthermore, the terminal block 23 may contact the second sealing flange 106 to further enhance the sealing between the connector 1 and the compressor 20.

[0148] Referring to Figures 4 to 6, the connector 1 also includes a connecting wire 15, a portion of which extends into the first chamber 1117 through the first port 1111 and is located in the first channel 101, and the connecting wire 15 is electrically connected to the connector terminal 12. When the connector terminal 12 is electrically connected to the compressor terminal 21, the connecting wire 15 can realize the electrical connection between the compressor 20 and the outside world. It should be noted that the connector 1 includes a plurality of connector terminals 12, and the connector 1 includes connecting wires 15 equal in number to the connector terminals 12, and each connector terminal 12 is connected to each connecting wire 15 in a one-to-one correspondence. Among them, the connecting wire 15 can be a soft wire, which can be twisted and deformed without affecting the assembly of the connector terminal 12 and the housing 11.

[0149] Referring to Figures 4 to 6 , connector 1 further includes a third sealing flange 107, which is disposed around the periphery of first port 1111. The third sealing flange 107 is connected to the housing 11 and protrudes from the housing 11. The third sealing flange 107 is configured to surround and seal the connection line 15. The third sealing flange 107 can be elastic and can be integrally formed with the housing 11. This simplifies the assembly process and provides a more reliable connection compared to separately forming the third sealing flange 107 and the housing 11 and then assembling them. Of course, the housing 11 and the third sealing flange 107 can also be separately formed and then assembled, allowing for flexible design based on actual usage requirements.

[0150] It should be noted that when the housing 11 includes multiple first chambers 1117, if the first ports 1111 of the multiple first chambers 1117 are independent of each other, the number of third sealing flanges 107 can be equal to the number of first ports 1111, and each third sealing flange 107 is provided corresponding to a first port 1111, and each third sealing flange 107 is used to seal the connection line 15 in the corresponding first chamber 1117. If the first ports 1111 of the multiple first chambers 1117 are connected, the number of third sealing flanges 107 can be one, and one third sealing flange 107 is provided around the periphery of all first ports 1111, and the one third sealing flange 107 is sealed with the connection line 15. In this embodiment of the present application, the housing 11 includes a third sealing flange 107 provided around the periphery of all first ports 1111 to simplify the sealing process between the third sealing flange 107 and the connection line 15. The multiple connection lines 15 can be wrapped together with a coating material.

[0151] In one exemplary embodiment, the connector 1 further includes a cable tie (not shown), and the third sealing flange 107 and the connecting wire 15 can be sealed by the cable tie. For example, the cable tie is wrapped around the periphery of the third sealing flange 107 and tightens the third sealing flange 107 and the connecting wire 15. In another exemplary embodiment, the third sealing flange 107 and the connecting wire 15 are sealed with a sealant. In yet another exemplary embodiment, the third sealing flange 107 and the connecting wire 15 can be tightened with a cable tie and then sealed with a sealant.

[0152] 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.

[0153] Example 2:

[0154] Referring to Figures 7 to 10, an embodiment of the present application provides a connector 1, comprising a housing 11, a connector terminal 12, and a retaining member 13. The housing 11 defines a first chamber 1117. The connector terminal 12 and the retaining member 13 are both located within the first chamber 1117. The retaining member 13 comprises a first retaining portion 131 and a second retaining portion 132. The first retaining portion 131 and the second retaining portion 132 are located on opposite sides of the connector terminal 12 along the circumference of the connector terminal 12. The circumference of the connector terminal 12 may be a direction surrounding a plug-in direction, wherein the plug-in direction is the direction in which the compressor terminal 21 is connected to the connector terminal 12.

[0155] In the embodiment of the present application, the first limiting portion 131 and the second limiting portion 132 of the limiting member 13 can limit the installation position of the connector terminal 12 within the first cavity 1117, thereby improving the installation accuracy of the connector terminal 12 within the first cavity 1117. The improved installation accuracy of the connector terminal 12 within the first cavity 1117 can improve the alignment accuracy when connecting the connector terminal 12 and the compressor terminal 21, facilitate connection, and reduce collision between the connector terminal 12 and the compressor terminal 21.

[0156] At least one of the first limiting portion 131 and the second limiting portion 132 may be elastic. If the first limiting portion 131 and / or the second limiting portion 132 are elastic, the elastic first limiting portion 131 and the second limiting portion 132 may be appropriately deformed according to the change in the clearance margin within the first chamber 1117 during the connection process between the connector terminal 12 and the compressor terminal 21 of the compressor assembly 20 and / or after the two are connected, and thus will not hinder the electrical connection between the connector terminal 12 and the compressor terminal 21. It should be noted that the first limiting portion 131 and the second limiting portion 132 may also be non-elastic. When the connector terminal 12 and the compressor terminal 21 are electrically connected, the first limiting portion 131 and the second limiting portion 132 may be crushed; in this case, the first limiting portion 131 and the second limiting portion 132 can be assembled in one go.

[0157] It is worth mentioning that due to factors such as manufacturing errors, the compressor terminals 21 of the compressor assembly 20 are inevitably subject to tolerances. For example, there are certain tolerances in the thickness of the compressor terminals 21, the inclination of the compressor terminals 21, the spacing between adjacent compressor terminals 21 when the compressor assembly 20 includes multiple compressor terminals 21, etc. The first limiting portion 131 and / or the second limiting portion 132 are elastic. The elastic first limiting portion 131 and the second limiting portion 132 can appropriately deform according to changes in the clearance margin within the first chamber 1117, and can also adapt to the tolerance of the compressor terminals 21, so that the compressor terminals 21 can still effectively electrically connect to the connector terminals 12 even when there are tolerances.

[0158] It should be noted that the first limiting portion 131 and / or the second limiting portion 132 are elastic, including: the first limiting portion 131 in the first limiting portion 131 and the second limiting portion 132 is elastic, the second limiting portion 132 in the first limiting portion 131 and the second limiting portion 132 is elastic, and both the first limiting portion 131 and the second limiting portion 132 are elastic.

[0159] In the embodiment of the present application, the first limiting portion 131 and the second limiting portion 132 are both elastic, so that during the connection process between the connector terminal 12 and the compressor terminal 21 and / or after the two are connected in place, the first limiting portion 131 and the second limiting portion 132 can be appropriately deformed according to the specific space margin, thereby improving the tolerance range of the compressor terminal 21 adapted by the connector 1 and improving the flexibility of use of the connector 1.

[0160] In particular, along the extension direction of the connector terminal 12, the first limiting portion 131 can be provided corresponding to a portion of the connector terminal 12, or the first limiting portion 131 can be provided corresponding to the entire extension direction of the connector terminal 12, so that the first limiting portion 131 can limit the installation position of the connector terminal 12 along the entire extension direction. Along the extension direction of the connector terminal 12, the second limiting portion 132 can be provided corresponding to a portion of the connector terminal 12, or the second limiting portion 132 can be provided corresponding to the entire extension direction of the connector terminal 12, so that the second limiting portion 132 can limit the installation position of the connector terminal 12 along the entire extension direction.

[0161] Referring to Figures 11 and 12 , the thickness G1 of the first limiter 131 can satisfy the following: 0.2mm ≤ G1 ≤ 2mm. By properly limiting the thickness of the first limiter 131, the first limiter 131 has sufficient deformation space to prevent damage to the compressor terminal 21 and the connector terminal 12 due to forced insertion, while also preventing excessive deformation space from causing the connector 1 to become oversized. Optionally, G1 can be 0.2mm, 0.4mm, 0.8mm, 1.2mm, 1.5mm, 1.8mm, 2mm, and so on, without limitation.

[0162] The thickness G2 of the second limiter 132 can satisfy the following: 0.2mm≤G2≤2mm. By properly limiting the thickness of the second limiter 132, the second limiter 132 has sufficient room for deformation, preventing damage to the compressor terminal 21 and the connector terminal 12 due to forced insertion, while also preventing excessive room for deformation, which could result in the connector 1 becoming oversized. Optionally, G2 can be 0.2mm, 0.4mm, 0.8mm, 1.2mm, 1.5mm, 1.8mm, 2mm, and so on, without limitation.

[0163] The thickness G2 of the second limiting portion 132 may be equal to or different from the thickness G1 of the first limiting portion 131 , and can be flexibly designed based on actual needs.

[0164] The connector terminal 12 may have a plugging surface 121 and a back surface 122 opposite to the plugging surface 121. The plugging surface 121 is used to contact the compressor terminal 21 when the connector terminal 12 is connected to the compressor terminal 21, and the back surface 122 is used to face away from the compressor terminal 21 when the connector terminal 12 is connected to the compressor terminal 21. The plugging surface 121 may extend along the plugging direction between the compressor terminal 21 and the connector terminal 12.

[0165] At least one of the first limiting portion 131 and the second limiting portion 132 is disposed on the side of the rear surface 122 of the connector terminal 12. Thus, when the compressor terminal 21 is connected to the connector terminal 12, the compressor terminal 21 can bend the connector terminal 12, allowing the connector terminal 12 to deform toward the side of the rear surface 122 away from the plugging surface 121. Furthermore, the ability of the connector terminal 12 to deform toward the side of the rear surface 122 away from the plugging surface 121 can also accommodate the tolerance of the compressor terminal 21.

[0166] It should be noted that if one of the first limiting portion 131 and the second limiting portion 132 is arranged on the side where the back of the connector terminal 12 is located, and the other is arranged on the side where the plug-in surface 121 of the connector terminal 12 is located, the one located on the side where the plug-in surface 121 of the connector terminal 12 is located is spaced apart from the plug-in surface 121, so that space can be reserved between the two for inserting the compressor terminal 21.

[0167] In the embodiment of the present application, the insertion surface 121 of the connector terminal 12 defines an insertion hole 123 for accommodating at least a portion of the compressor terminal 21. The first limiting portion 131 and the second limiting portion 132 are both located on the side where the back surface 122 is located. The first limiting portion 131 and the second limiting portion 132 both abut against the connector terminal 12. In this way, the first limiting portion 131 and the second limiting portion 132 can roughly center the connector terminal 12 to better connect with the compressor terminal 21.

[0168] The plug-in surface 121 may define a ring-shaped plug-in hole 123 or a non-ring-shaped plug-in hole 123 , as shown in FIG. 11 and FIG. 12 , so that the connector terminal 12 is more easily deformed.

[0169] Referring to Figures 9 and 10 , the retaining member 13 may include only a first retaining portion 131 and a second retaining portion 132. Referring to Figures 11 and 12 , the retaining member 13 may also include, in addition to the first retaining portion 131 and the second retaining portion 132, a third retaining portion 133 and a fourth retaining portion 134. Along the circumference of the connector terminal 12, the third retaining portion 133 and the fourth retaining portion 134 are located on opposite sides of the connector terminal 12, with the third retaining portion 133 located between the first retaining portion 131 and the second retaining portion 132, and the fourth retaining portion 134 located between the first retaining portion 131 and the second retaining portion 132. The provision of the third retaining portion 133 and the fourth retaining portion 134 can further improve the installation accuracy of the connector terminal 12 within the first cavity 1117, thereby improving the alignment accuracy when connecting the connector terminal 12 to the compressor terminal 21, and facilitating connection.

[0170] The third limiting portion 133 and / or the fourth limiting portion 134 are elastic. Thus, during the connection process between the connector terminal 12 and the compressor terminal 21 of the compressor assembly 20 and / or after the two are properly connected, the elastic third limiting portion 133 and the fourth limiting portion 134 can appropriately deform according to the change in the clearance margin within the first chamber 1117, without hindering the electrical connection between the connector terminal 12 and the compressor terminal 21.

[0171] It should be noted that the third limiting portion 133 and / or the fourth limiting portion 134 are elastic, including: the third limiting portion 133 in the third limiting portion 133 and the fourth limiting portion 134 is elastic, the fourth limiting portion 134 in the third limiting portion 133 and the fourth limiting portion 134 is elastic, and the third limiting portion 133 and the fourth limiting portion 134 are both elastic.

[0172] In the embodiment of the present application, the third limiting portion 133 and the fourth limiting portion 134 are both elastic, so that during the connection process between the connector terminal 12 and the compressor terminal 21 and / or after the two are connected in place, the third limiting portion 133 and the fourth limiting portion 134 can be appropriately deformed according to the specific space margin, thereby improving the tolerance range of the compressor terminal 21 adapted by the connector 1 and improving the flexibility of use of the connector 1.

[0173] Along the extension direction of the connector terminal 12, the third limiting portion 133 can be provided corresponding to a portion of the connector terminal 12, or the third limiting portion 133 can be provided corresponding to the entire extension direction of the connector terminal 12, so that the third limiting portion 133 can limit the installation position of the connector terminal 12 along the entire extension direction. Along the extension direction of the connector terminal 12, the fourth limiting portion 134 can be provided corresponding to a portion of the connector terminal 12, or the fourth limiting portion 134 can be provided corresponding to the entire extension direction of the connector terminal 12, so that the fourth limiting portion 134 can limit the installation position of the connector terminal 12 along the entire extension direction.

[0174] Along the circumference of the connector terminal 12, the third limiting portion 133 and the first limiting portion 131 may be spaced apart, as shown in FIG11 , or may be connected to the first limiting portion 131 , as shown in FIG12 . Along the circumference of the connector terminal 12, the fourth limiting portion 134 and the first limiting portion 131 may be spaced apart, as shown in FIG11 , or may be connected to the first limiting portion 131 , as shown in FIG12 . Along the circumference of the connector terminal 12, the third limiting portion 133 and the second limiting portion 132 may be spaced apart, as shown in FIG11 , or may be connected to the second limiting portion 132 , as shown in FIG12 . Along the circumference of the connector terminal 12, the fourth limiting portion 134 and the second limiting portion 132 may be spaced apart, as shown in FIG11 , or may be connected to the second limiting portion 132 , as shown in FIG12 . The structure of the limiting member 13 can be diversified to meet more usage requirements.

[0175] At least one of the first limiting portion 131, the second limiting portion 132, the third limiting portion 133, and the fourth limiting portion 134 can be connected to the housing 11, thereby improving the installation stability of the portion connected to the housing 11 within the first cavity 1117. If at least one of the first limiting portion 131, the second limiting portion 132, the third limiting portion 133, and the fourth limiting portion 134 is connected to the housing 11, the housing 11 can be first connected to at least one of the first limiting portion 131, the second limiting portion 132, the third limiting portion 133, and the fourth limiting portion 134, and then the connector terminal 12 can be assembled into the first cavity 1117.

[0176] It should be noted that at least one of the first limiting portion 131, the second limiting portion 132, the third limiting portion 133, and the fourth limiting portion 134 can also be clamped between the connector terminal 12 and the shell 11, which can simplify the connection steps between the limiting portion 13 and the shell 11 and improve assembly efficiency.

[0177] Referring again to FIG. 9 , the housing 11 is formed with a first port 1111 communicating with the first chamber 1117 . The connector terminal 12 is configured to be electrically connected to the compressor terminal 21 extending into the first chamber 1117 via the first port 1111 .

[0178] The inner wall 113 of the first chamber 1117 includes a guide surface 1131 adjacent to the first port 1111. The guide surface 1131 surrounds the first port 1111 and has an inner diameter that gradually decreases from one end to the other end of the first port 1111. The provision of the guide surface 1131 can guide the compressor terminal 21 when it is inserted into the first chamber 1117.

[0179] A portion of the inner wall 113 of the first cavity 1117 is raised to form a raised portion 114. The connector terminal 12 has a first end surface 1221 adjacent to the first port 1111 and a mating surface 121 for electrical connection with the compressor terminal 21. The raised portion 114 is located on the side of the first end surface 1221 of the connector terminal 12. When viewed from the first port 1111 of the housing 11, the raised portion 114 obscures at least a portion of the boundary between the first end surface 1221 and the mating surface 121. The provision of the raised portion 114 reduces the likelihood of the compressor terminal 21 colliding with the first end surface 1221 of the connector terminal 12 when inserted into the first cavity 1117, thereby facilitating smoother insertion of the compressor terminal 21 into the first cavity 1117. Referring to FIG. 8 , the partially obscured portion of the connector terminal 12 will be described in more detail below.

[0180] It should be noted that the inner wall surface 113 of the first chamber 1117 has a smooth transition between the protrusion 114 and the first port 1111, eliminating the dull feeling when the compressor terminal 21 is inserted into the protrusion 114, and eliminating the obstruction of the protrusion 114 to the compressor terminal 21 inserted into the first chamber 1117.

[0181] Referring to Figures 7 to 10, the connector 1 may include at least two connector terminals 12, and the housing 11 may be formed with at least two first cavities 1117, the number of which is equal to the number of the at least two connector terminals 12. Each connector terminal 12 is mounted in a one-to-one correspondence within each first cavity 1117. For example, the connector 1 may include two connector terminals 12 and the housing 11 may be formed with two first cavities 1117; alternatively, the connector 1 may include three connector terminals 12 and the housing 11 may be formed with three first cavities 1117, and so on, without limitation.

[0182] It can be understood that when the connector 1 includes at least two connector terminals 12 , the compressor assembly 20 includes at least two compressor terminals 21 equal in number to the at least two connector terminals 12 , and each compressor terminal 21 is electrically connected to each connector terminal 12 in a one-to-one correspondence.

[0183] 13 and 14 , the housing 11 may include a first housing portion 111 and a second housing portion 112. The first housing portion 111 is formed with the first port 1111 and a second port 1114 communicating with the first chamber 1117. The connector terminal 12 is mounted on the first housing portion 111 via the second port 1114. The second housing portion 112 is connected to the first housing portion 111. Disassembling the housing 11 into the first housing portion 111 and the second housing portion 112 facilitates assembly of the connector terminal 12.

[0184] It should be noted that when at least two first chambers 1117 are formed on the shell 11, the first shell portion 111 has first ports 1111 equal in number to the first chambers 1117 and second ports 1114 equal in number to the first chambers 1117. Each first port 1111 is connected to each first chamber 1117, and each second port 1114 is connected to each first chamber 1117.

[0185] The first housing portion 111 has a higher heat resistance than the second housing portion 112. Compared to the second housing portion 112, the first housing portion 111 is less likely to deform under high temperature conditions. Thus, by disposing the first port 1111 in the first housing portion 111, when the connector 1 is connected to the compressor assembly 20, the first housing portion 111 is close to the compressor assembly 20. The first housing portion 111 has a higher heat resistance, which can prevent the internal connector terminals 12 from being softened by high temperatures, thereby extending the service life of the connector terminals 12.

[0186] The first housing portion 111 can be made of a highly heat-resistant material. For example, the first housing portion 111 can 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, a high-temperature and fire-resistant insulation material that prevents softening of the connector terminals 12 during operation.

[0187] 13 , the second housing portion 112 can cover the second port 1114 and the connector terminal 12. The provision of the second port 1114 facilitates installation of the connector terminal 12 within the housing 11. The second housing portion 112 covers the second port 1114 and the connector terminal 12, allowing the connector terminal 12 and the compressor terminal 21 to be enclosed by the housing 11 of the connector 1 when connected, thereby preventing the presence of refrigerant near the connector terminal 12 and the compressor terminal 21, which could easily cause ignition problems when the connector terminal 12 and the compressor terminal 21 are connected.

[0188] 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, so that the injection-molded housing portion and the first housing portion 111 are at least an integrally-molded structure. Specifically, after the first housing portion 111 is molded, at least the first housing portion 111 is placed in a mold to form a cavity for molding the injection-molded housing portion, and then a molding compound is injected into the cavity to obtain the injection-molded housing portion.

[0189] The glue-potted housing portion is formed by a glue-potting process, and the glue-potted housing portion is connected to the first housing portion 111. Therefore, the glue-potted housing portion and the first housing portion 111 are at least an integrally molded structure formed by glue-potting. Specifically, the first housing portion 111 is formed with a molding groove, and at least the molding groove participates in constructing the glue-potted housing portion. Then, molding material is injected into the molding groove to obtain the glue-potted housing portion.

[0190] In summary, regardless of whether the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, the second housing portion 112 and the first housing portion 111 can be integrally formed. Compared to independently molding the second housing portion 112 and the first housing portion 111 and then assembling them, the tightness of the connection between the second housing portion 112 and the first housing portion 111 can be improved, as can the sealing between the second housing portion 112 and the first housing portion 111. The second housing portion 112 and the first housing portion 111 of the connector 1 are sealed, and when the connector 1 is connected to the compressor assembly 20, the first housing portion 111 and the surface of the compressor assembly 20 are sealed due to the presence of the seal 17. In this way, the overall sealing of the connector 1 can be improved.

[0191] The second housing portion 112 can be made of a sealant shell, which provides excellent sealing performance. The second housing portion 112 can be elastic or non-elastic, allowing for flexible design based on actual needs. In the embodiment of the present application, the second housing portion 112 can be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing properties. The second housing portion 112 can be made of plastic or silicone, without limitation.

[0192] To enhance the connection reliability between the second housing portion 112 and the first housing portion 111, one of the second housing portion 112 and the first housing portion 111 can be provided with a hook 1121, and the other can be provided with a slot 1115 that matches the hook 1121, with the hook 1121 located within the slot 1115. The second housing portion 112 and the first housing portion 111 can be hooked together via the hook 1121, preventing them from easily disengaging. It is understood that the second housing portion 112 can be provided with the hook 1121 and the first housing portion 111 can be provided with the slot 1115; alternatively, the second housing portion 112 can be provided with the slot 1115 and the first housing portion 111 can be provided with the hook 1121, without limitation.

[0193] 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 1.

[0194] In conjunction with Figure 13, the connector 1 also includes a cover member, which covers the second port 1114, and the second housing portion 112 covers the cover member. Under the protection of the cover member, impurities such as moisture and dust can be prevented from entering the first housing portion 111 and affecting the performance of the connector terminal 12. Moreover, when the second housing portion 112 includes an injection-molded housing portion or a glue-potted housing portion, under the protection of the cover member, the molding material of the second housing portion 112 will not pass through the second port 1114 to reach the connector terminal 12, wrapping the connector terminal 12, thereby ensuring effective electrical connection between the connector terminal 12 and the compressor terminal 21.

[0195] The connector terminal 12 and the cover member may abut 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, thereby preventing the connector terminal 12 and the compressor terminal 21 from being damaged by forced insertion.

[0196] 13 and 14 , the cover assembly may include a cover plate 14 . The cover plate 14 covers the second port 1114 and the connector terminal 12 . The second housing portion 112 covers the cover plate 14 .

[0197] One of the cover plate 14 and the first housing portion 111 can be provided with a limiting protrusion 141, and the other can be provided with a limiting groove 1116, with the limiting protrusion 141 located within the limiting groove 1116. The provision of the limiting protrusion 141 and the limiting groove 1116 can facilitate positioning of the cover plate 14 and the first housing portion 111 during assembly, thereby improving assembly efficiency of the cover plate 14 and the first housing portion 111. It is 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; alternatively, 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, without limitation. 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 the limiting groove 1116.

[0198] If the housing 11 is formed with multiple first chambers 1117 and multiple second ports 1114, the cover 14 covers all of the second ports 1114. Referring to Figures 13 and 14, the connector 1 also includes a seal 17. Seal 17 is located on the side of the housing 11 that is connected to the compressor assembly 20. Seal 17 is connected to the housing 11. The provision of seal 17 allows the interface between the connector 1 and the compressor assembly 20 to be sealed when the connector 1 and the compressor assembly 20 are connected.

[0199] It is understood that opposite sides of the seal 17 may respectively abut the surface of the compressor assembly 20 and the housing 11 to achieve sealing between the surface of the compressor assembly 20 and the housing 11. In an exemplary embodiment, the seal 17 may be provided on an end surface of the housing 11. In this case, in order to achieve a reliable connection between the seal 17 and the housing 11, the seal 17 and the housing 11 may be connected by means of an adhesive or the like to prevent the seal 17 from falling off.

[0200] In another exemplary embodiment, the end face of the shell 11 can be provided with an annular groove 1113, and part of the seal 17 can be located in the annular groove 1113. The setting of the annular groove 1113 can, on the one hand, position 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; on the other hand, it can have a restraining effect on the seal 17, thereby accommodating the deformation of the seal 17 caused by extrusion and making it difficult to move.

[0201] Referring to FIG. 13 , the portion of the seal 17 located in the annular groove 1113 may include: 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 within 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 deform when the connector 1 is connected to the compressor assembly 20, thereby improving the tightness of the connection between the connector 1 and the compressor assembly 20.

[0202] The sealing member 17 may be mounted in the annular groove 1113 by snapping, or by bonding or other methods, which are not limited thereto.

[0203] It should be noted that if the housing 11 includes the first housing portion 111 and the second housing portion 112 described above, the seal 17 is connected to the first housing portion 111. By arranging the seal 17 in the first housing portion 111, even if heat from the surface of the compressor assembly 20 is transferred to the seal 17 and the first housing portion 111, the first housing portion 111 is not easily deformed, thereby providing a stable support effect for the seal 17, ensuring the sealing performance between the compressor assembly 20 and the connector 1, and at the same time ensuring the smooth connection between the compressor assembly 20 and the connector 1.

[0204] 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. The seal 17 is elastic so that when the connector 1 is connected to the compressor assembly 20, the seal 17 can be in a compressed state to improve the tightness of the connection between the connector 1 and the compressor assembly 20. The seal 17 has high heat resistance, which can prevent the seal 17 from being damaged by the surface heat of the compressor assembly 20, thereby improving 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.

[0205] 13 and 14 , the housing 11 (e.g., the first housing portion 111) may further include a second chamber 1118 in communication with the first chamber 1117. The second chamber 1118 is closer to the compressor assembly 20 than the first chamber 1117. Along the plugging direction, the cross-sectional profile of the second chamber 1118 is larger than the cross-sectional profiles of all the first chambers 1117. Furthermore, along the plugging direction, the cross-sectional profiles of all the first chambers 1117 are located within the cross-sectional profile of the second chamber 1118. Thus, when the connector 1 includes at least two connector terminals 12 and the compressor assembly 20 includes at least two compressor terminals 21, when the compressor terminals 21 are connected to the connector terminals 12, all the compressor terminals 21 can pass through the second chamber 1118 and then reach the corresponding first chamber 1117, thereby achieving electrical connection with the corresponding connector terminals 12. Further, referring to Figure 15, the compressor assembly 20 may include a terminal seat 23 for fixing the compressor terminal 21, the terminal seat 23 protrudes relative to the compressor body, and when the compressor terminal 21 is connected to the connector terminal 12, the terminal seat 23 can be located in the second chamber 1118.

[0206] It is understood that the annular groove 1113 may or may not be in communication with the second chamber 1118. In the embodiment of the present application, the annular groove 1113 is not in communication with the second chamber 1118, which can prevent the seal 17 from deforming toward the second chamber 1118 during compression deformation, thereby affecting the installation stability of the seal 17.

[0207] Referring again to Figures 13 and 14, the connector 1 also includes a connecting wire 15, which is electrically connected to the connector terminal 12 and is used to enable signal interaction between the compressor assembly 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 portion 112 to improve the connection reliability between the connecting wire 15 and the connector terminal 12 and improve the sealing of the connector 1. Specifically, when the second shell portion 112 includes an injection molding shell portion and / or a glue-filling shell portion, the second shell portion 112 can directly wrap the end of the connecting wire 15 connected to the connector terminal 12 during injection molding and / or glue-filling. If the connector 1 includes multiple connector terminals 12, the connecting wire 15 is electrically connected to the multiple connector terminals 12.

[0208] 14 and 15 , the connector 1 further includes a first connector 16. The compressor assembly 20 is provided with a second connector 22. The first connector 16 is connected to the second connector 22 to improve the connection reliability between the connector 1 and the compressor assembly 20. The first connector 16 and the second connector 22 can be connected by plugging, snap-fitting, threading, or the like, without limitation.

[0209] Optionally, the first connector 16 is provided with a mounting hole 161, and at least a portion of the second connector 22 is inserted into the mounting hole 161. In this way, the provision of the mounting hole 161 can play a guiding role during the assembly process of the connector 1 and the compressor assembly 20.

[0210] The connector 1 may include a single first connector 16, or may include multiple first connectors 16 spaced apart. If the connector 1 includes multiple first connectors 16, the compressor assembly 20 includes multiple second connectors 22, with each first connector 16 corresponding to each second connector 22. The cross-section of the first connector 16 may be generally annular or arcuate, without limitation.

[0211] The inner wall of the mounting hole 161 may include a first plane (not shown) extending in the plugging direction, and the outer wall of the second connector 22 may include a second plane extending in the plugging direction, with the first plane corresponding to the second plane. The first and second planes prevent relative rotation between the first and second connectors 16 and 22 during connection.

[0212] In an embodiment of the present application, the first connecting member 16 and the second connecting member 22 are also connected by a nut locking connection. Specifically, the second connecting member 22 passes through the mounting hole 161 and is fixed with the nut by thread. By tightening the nut, the distance between the compressor assembly 20 and the connector 1 can be shortened, thereby achieving the tightening of the seal 17.

[0213] Next, the connector terminal 12 will be described in detail.

[0214] The connector terminal 12 can be any terminal, and the compressor terminal 21 can be any terminal, as long as the compressor terminal 21 and the connector terminal 12 can be electrically connected.

[0215] For example, one of the connector terminal 12 and the compressor terminal 21 can be a male terminal, and the other can be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, and the compressor terminal 21 is a male terminal. The connector terminal 12 is formed with an insertion hole 123, and at least a portion of the compressor terminal 21 is inserted into the insertion hole 123 and electrically connected to the connector terminal 12. In other words, when the connector terminal 12 and the compressor terminal 21 are connected, at least a portion of the compressor terminal 21 is surrounded by the connector terminal 12, which can improve the connection reliability between the connector terminal 12 and the compressor terminal 21.

[0216] In an exemplary embodiment, referring to FIG. 16 and FIG. 17 , the connector terminal 12 includes a first main plate 124 , two first bent plates 125 connected to the first main plate 124 , and two second bent plates 126 connected to the first main plate 124 .

[0217] In this exemplary solution, the first main board 124 extends along the above-mentioned plug-in direction, and the two first bent plates 125 are located on the same side of the first main board 124 along a direction perpendicular to the board surface of the first main board 124. The two first bent plates 125 are respectively located on opposite sides of the first main board 124 along a direction perpendicular to the plug-in direction and parallel to the board surface of the first main board 124. One end of each first bent plate 125 is connected to the first main board 124, and the other end of each first bent plate 125 is bent and extended in a direction away from the first main board 124; each second bent plate 125 One end of 6 is respectively connected to one end of each first bent plate 125 away from the first main board 124, and the other end of each second bent plate 126 is bent and extended in a direction close to each other and close to the first main board 124. Each second bent plate 126 is spaced apart from the first main board 124 to form a first plugging hole 1231. The two second bent plates 126 are spaced apart in a direction perpendicular to the plugging direction and parallel to the plate surface of the first main board 124 to form a second plugging hole 1232. The plugging hole 123 includes a first plugging hole 1231 and a second plugging hole 1232.

[0218] In this exemplary embodiment, the connector terminal 12 has a relatively stable structure and is not easily deformed. Both the first insertion hole 1231 and the second insertion hole 1232 can achieve connection with the compressor terminal 21, providing a more reliable connection. The insertion surface 121 of the connector terminal 12 may include a surface of the first main plate 124 proximal to the two first bent plates 125 and a surface of the two second bent plates 126 proximal to each other.

[0219] In this exemplary embodiment, the connector 1 may include multiple connector terminals 12. For example, referring to Figures 16 and 17 , the connector 1 includes three connector terminals 12: a first connector terminal 12a, a second connector terminal 12b, and a third connector terminal 12c. The first main plates 124 of the three connector terminals 12 are arranged at an angle to each other. Specifically, in a clockwise direction, the angle θ1 between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the second connector terminal 12b is greater than or equal to 20° and less than or equal to 40°, and the angle θ2 between the first main plate 124 of the first connector terminal 12a and the first main plate 124 of the third connector terminal 12c is greater than or equal to 50° and less than or equal to 70°. It will be appreciated that the orientation of the compressor terminal 21 corresponds to the orientation of the corresponding connector terminal 12. This arrangement ensures that each of the three connector terminals 12 and the three compressor terminals 21 can be plugged in in a suitable manner, i.e., each of the three connector terminals 12 and the three compressor terminals 21 can be matched in a suitable manner, thus preventing the possibility of incorrect insertion. It can be understood that the angle θ1 between the first main board 124 of the first connector terminal 12a and the first main board 124 of the second connector terminal 12b can be 20°, 25°, 30°, 35°, 40°, etc., and the angle θ2 between the first main board 124 of the first connector terminal 12a and the first main board 124 of the third connector terminal 12c can be 50°, 55°, 60°, 65°, 70°, etc.

[0220] In this exemplary embodiment, referring to FIG18 , the compressor terminal 21 may include a first plug-in portion 211 inserted into the first plug-in hole 1231, and a second plug-in portion 212 inserted into the second plug-in hole 1232. The first plug-in portion 211 may be a generally sheet-like structure extending in the plug-in direction, and the second plug-in portion 212 may be a generally columnar structure extending in the plug-in direction, thereby enhancing the structural strength of the compressor terminal 21 and preventing deformation. Along the plug-in direction, the cross-sectional profile of the first plug-in portion 211 may be generally narrow square, and the cross-sectional profile of the second plug-in portion 212 may be generally circular, without limitation. The first plug-in portion 211 may be connected to the second plug-in portion 212, and the first plug-in portion 211 may be connected to the main body of the compressor assembly 20.

[0221] In this exemplary embodiment, the first limiting portion 131 is disposed on a side of the first main plate 124 facing away from the second bent plate 126, and the second limiting portion 132 is disposed on a side of the second bent plate 126 facing away from the first main plate 124. The third limiting portion 133 and the fourth limiting portion 134 are located on sides of the two first bent plates 125 facing away from each other.

[0222] In this exemplary embodiment, the thickness G1 of the first limiting portion 131 may satisfy the following relationship: 0.4 mm ≤ G1 ≤ 1 mm. For example, G1 may be 0.4 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, etc., without limitation.

[0223] In this exemplary embodiment, the thickness G2 of the second limiting portion 132 can satisfy the following relationship: 0.4 mm ≤ G2 ≤ ​​1 mm. For example, G2 can be 0.4 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, etc., without limitation. The thickness G2 of the second limiting portion 132 can be equal to or different from the thickness G1 of the first limiting portion 131.

[0224] In this exemplary embodiment, connector terminal 12 includes a first end proximate to first port 1111, with first stopper 131 and second stopper 132 positioned corresponding to the first end. The first end is the portion of connector terminal 12 that compressor terminal 21 first passes through when extending into first chamber 1117. Positioning first stopper 131 and second stopper 132 corresponding to the first end limits the installation position of the portion of connector terminal 12 that compressor terminal 21 first passes through, improving alignment accuracy when connecting connector terminal 12 and compressor terminal 21, and facilitating connection.

[0225] In this exemplary embodiment, the third limiting portion 133 and the fourth limiting portion 134 are provided corresponding to the first end. The first end is the portion of the connector terminal 12 that the compressor terminal 21 first passes through when extending into the first chamber 1117. Thus, providing the third limiting portion 133 and the fourth limiting portion 134 corresponding to the first end can limit the installation position of the portion of the connector terminal 12 that the compressor terminal 21 first passes through, thereby improving the alignment accuracy when connecting the connector terminal 12 and the compressor terminal 21, and facilitating connection.

[0226] In this exemplary solution, when viewed from the first port 1111 of the housing 11 , the raised portion 114 blocks the first main board 124 .

[0227] In another exemplary embodiment, referring to Figures 19 to 22, the connector terminal 12 includes an electrical connection portion 127 for electrically connecting to the compressor terminal 21. The electrical connection portion 127 is located in the first cavity 1117 and encloses the plug hole 123 and the first port 1111.

[0228] In this exemplary embodiment, the compressor terminal 21 can be substantially cylindrical and extend in the plugging direction to simplify the structure of the compressor terminal 21 and reduce manufacturing costs. The cross-sectional profile of the compressor terminal 21 along the plugging direction can be substantially circular, square, etc., without limitation.

[0229] In this exemplary solution, the first limiting portion 131 , the second limiting portion 132 , the third limiting portion 133 and the fourth limiting portion 134 may be connected to form a ring structure and disposed around the outer periphery of the electrical connection portion 127 .

[0230] In this exemplary embodiment, the thickness G1 of the first limiting portion 131 may satisfy the following conditions: 0.1 mm ≤ G1 ≤ 1 mm. Furthermore, 0.1 mm ≤ G1 ≤ 0.8 mm. For example, G1 may be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.8 mm, etc., without limitation.

[0231] In this exemplary embodiment, the thickness G2 of the second limiting portion 132 can satisfy the following conditions: 0.1 mm ≤ G2 ≤ ​​1 mm. Furthermore, 0.1 mm ≤ G2 ≤ ​​0.8 mm. For example, G2 can be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.8 mm, and so on, without limitation. The thickness G2 of the second limiting portion 132 can be equal to or different from the thickness G1 of the first limiting portion 131.

[0232] In this exemplary embodiment, the electrical connection portion 127 includes an inlet portion 1271 and a mounting portion 1272 arranged along the insertion direction. The inlet portion 1271 is closer to the first port 1111 than the mounting portion 1272. That is, when the compressor terminal 21 is plugged into the connector terminal 12, it first enters the inlet portion 1271 and then enters the mounting portion 1272. The inner diameter of the inlet portion 1271 gradually decreases and then increases along the direction from the inlet portion 1271 to the mounting portion 1272. This allows the compressor terminal 21 to be connected to the inlet portion 1271 of the connector terminal 12, where it is constrained by the smaller diameter of the inlet portion 1271. This prevents the risk of mismatching between the compressor assembly 20 and the connector 1, leading to incorrect insertion. Furthermore, the larger diameter of the mounting portion 1272 facilitates and improves installation efficiency when the compressor terminal 21 is connected to the mounting portion 1272 of the connector terminal 12. The inner diameter of the introduction portion 1271 gradually decreases and then increases along the direction from the introduction portion 1271 to the mounting portion 1272. This allows the inner diameter of the introduction portion 1271 to change smoothly, thereby improving the smoothness of the connection between the compressor terminal 21 and the connector terminal 12.

[0233] In this exemplary solution, the limiting member 13 may be provided corresponding to the mounting portion 1272. In this embodiment, along the plugging direction, the inner diameter of the mounting portion 1272 may remain substantially unchanged, and the outer diameter of the mounting portion 1272 may also remain substantially unchanged.

[0234] In this exemplary embodiment, the end surface of the electrical connection portion 127 closest to the first port 1111 is a first end surface 1221. When viewed from the first port 1111 of the housing 11, the raised portion 114 obscures the first end surface 1221. If the electrical connection portion 127 includes an introduction portion 1271 and a mounting portion 1272, the end surface of the introduction portion 1271 facing away from the mounting portion 1272 is the first end surface 1221.

[0235] In this exemplary embodiment, referring to FIG. 22 , the connector terminal 12 may be provided with at least one notch 1273 . The notch 1273 extends along the axis of the insertion hole 123 and penetrates the end of the connector terminal 12 near the first port 1111 . This allows the connector terminal 12 to easily deform when the compressor terminal 21 is initially inserted into the connector terminal 12 due to the notch 1273 , thereby accommodating tolerances of the compressor terminal 21 , such as thickness, tilt, etc. The notch 1273 may be provided on the electrical connection portion 127 .

[0236] In this exemplary embodiment, if the connector 1 includes a cover, the cover may include a cover plate 14, which may also include a blocking portion 128. The blocking portion 128 is located on the side of the electrical connection portion 127 near the second port 1114. The blocking portion 128 and the electrical connection portion 127 are integrally formed. The second housing portion 112 covers the blocking portion 128, which in turn covers the second port 1114. Alternatively, the blocking portion 128 covers the insertion hole 123 of the electrical connection portion 127. In other words, there is no need to provide a separate cover plate 14. Instead, the blocking portion 128 on the connector terminal 12 can directly cover the second port 1114 or insertion hole 123. This prevents molding compound from entering the electrical connection portion 127 through the second port 1114 or insertion hole 123 during the formation of the injection-molded or potted housing portion, thereby affecting the effective electrical connection between the electrical connection portion 127 and the compressor terminal 21.

[0237] In this exemplary solution, the blocking portion 128 can be formed by local stamping and bending of the electrical connection portion 127, which has a simple processing technology and saves materials; for example, the blocking portion 128 is formed by stamping and bending the material corresponding to a stamping hole on the electrical connection portion 127.

[0238] In this exemplary embodiment, one of the electrical connection portion 127 and the housing 11 (e.g., the first housing portion 111) may be formed with a rib 1291, and the other may be provided with a groove, with the rib 1291 located within the groove. The provision of the rib 1291 and the groove can improve the connection reliability between the electrical connection portion 127 and the housing 11. The rib 1291 may extend circumferentially or axially of the insertion hole 123, without limitation.

[0239] In this exemplary embodiment, the connector terminal 12 may further include a overlapping portion 1292, which protrudes outward relative to the electrical connection portion 127, and the overlapping portion 1292 is used to overlap the shell 11 (such as the first shell portion 111) to limit the depth of the connector terminal 12 inserted into the first shell portion 111, etc.

[0240] In this exemplary embodiment, if the housing 11 includes a first housing portion 111 and a second housing portion 112, the connector terminal 12 may further include an embedding portion 1293, which is embedded in the housing 11 (e.g., the second housing portion 112). In this manner, when the second housing portion 112 includes an injection-molded housing portion and / or a potted housing portion, the embedding portion 1293 is integrally connected to the second housing portion 112, thereby improving the installation stability of the connector terminal 12 in the housing 11.

[0241] It should be noted that even if the embedding portion 1293 is embedded in the second housing portion 112, the electrical connection portion 127 is provided with a circumferential limiter 13. Therefore, when the electrical connection portion 127 is electrically connected to the compressor terminal 21, it can still squeeze the limiter 13 to adapt to the tolerance of the compressor terminal 21. In addition, the use of a sealing rubber shell with a certain degree of elasticity in the second housing portion 112 can also allow the electrical connection portion 127 to have a certain degree of deflection.

[0242] Secondly, referring to FIG. 23 , an embodiment of the present application further provides a compressor assembly 2 including a connector 1 , a compressor assembly 20 and a seal 30 .

[0243] Referring to Figures 24 and 25 , Figure 24 is a schematic cross-sectional view taken along the DD direction in Figure 23 , and Figure 25 is an exploded cross-sectional view of the connector 1 and seal 30 in Figure 24 . The connector 1 includes a housing 11 having a first port 1111 formed therein. The compressor assembly 20 includes a casing 24. The connector 1 is positioned outside the casing 24, with the first port 1111 of the casing 11 facing the casing 24. The seal 30 includes a sealing gasket 31 positioned between the connector 1 and the casing 24 and having a first mounting hole 311 in communication with the first port 1111.

[0244] The seal 30 that seals the connector 1 and the compressor assembly 20 is independent of the connector 1 and the compressor assembly 20, allowing the seal 30 to be independently molded. This simplifies the molding process of the seal 30 and improves product yield. Furthermore, the seal 30 includes a gasket 31, which is positioned between the connector 1 and the housing 24 of the compressor assembly 20 to seal the connector 1 and the compressor assembly 20. A first mounting hole 311 is provided on the gasket 31 to facilitate positioning the seal 30 on the compressor assembly 20 and facilitate connection between the connector 1 and the compressor assembly 20 after passing through the first mounting hole 311.

[0245] Furthermore, the sealing member 30 also includes a sealing ring 32, a sealing gasket 31 is located between the connector 1 and the housing 24, and the sealing gasket 31 is provided with a first mounting hole 311 connected to the first port 1111. The sealing ring 32 is connected to the sealing gasket 31 and protrudes on the side of the sealing gasket 31 close to the connector 1. The sealing ring 32 is arranged around the first mounting hole 311, and the sealing ring 32 passes through the first port 1111 and is located in the shell 11 and fits with the inner wall of the shell 11. In this way, the sealing ring 32 passes through the first port 1111 and is located in the shell 11 and fits with the inner wall of the shell 11, which can achieve a circumferential seal with the connector 1. That is, the present application can achieve a seal between the connector 1 and the compressor assembly 20 through the sealing gasket 31, and can also achieve a circumferential seal with the connector 1 through the sealing ring 32, thereby improving the sealing performance of the compressor assembly 2.

[0246] Referring to Figure 25 , the inner wall of the sealing ring 32 smoothly transitions with the inner wall of the first mounting hole 311 formed by the sealing gasket 31. This facilitates the connection between the connector 1 and the compressor assembly 20 after passing through the first mounting hole 311 and the sealing ring 32. Furthermore, when viewed along the first mounting hole 311, the inner wall of the sealing ring 32 and the inner wall of the first mounting hole 311 formed by the sealing gasket 31 can substantially overlap, further facilitating the connection between the connector 1 and the compressor assembly 20 after passing through the first mounting hole 311 and the sealing ring 32, and facilitating the formation of the seal 30.

[0247] The seal 30 can be any device with sealing performance. In the embodiment of the present application, the seal 30 is a device with elasticity and high heat resistance. The seal 30 is elastic so that when the connector 1 is connected to the compressor assembly 20, the seal 30 can be in a compressed state to improve the tightness of the connection between the connector 1 and the compressor assembly 20. The seal 30 has high heat resistance, which can prevent the seal 30 from being damaged by the surface heat of the compressor assembly 20 and improve the service life of the seal 30. Specifically, the seal 30 can be a silicone rubber seal, which has low cost and is elastic and highly heat-resistant.

[0248] A first mounting hole 311 is provided on the sealing gasket 31 to facilitate positioning the sealing member 30 on the compressor assembly 20 and facilitate connection between the connector 1 and the compressor assembly 20 after passing through the first mounting hole 311. For example, the compressor terminal 21 of the compressor assembly 20 passes through the first mounting hole 311 to electrically connect with the connector terminal 12 of the connector 1. Specifically, referring to Figures 24 and 25, the connector 1 includes a connector terminal 12 located within the housing 11, and the compressor assembly 20 includes a compressor terminal 21 mounted on the casing 24, with at least a portion of the compressor terminal 21 protruding from the casing 24. The compressor terminal 21 passes through the first mounting hole 311 and the sealing ring 32 to electrically connect with the connector terminal 12 within the casing 11. Thus, the provision of the sealing gasket 31 can prevent R290 refrigerant, flammable and explosive refrigerant, or combustible refrigerant from entering the connector terminal 12 and the compressor terminal 21 when the compressor assembly 20 uses the refrigerant, thereby preventing sparks when the connector terminal 12 and the compressor terminal 21 are connected.

[0249] 24 and 25 , the compressor assembly 20 may further include a terminal block 23 for mounting the compressor terminal 21 . The terminal block 23 is mounted on the housing 24 and at least partially protrudes from the housing 24 . The terminal block 23 facilitates the installation of the compressor terminal 21 .

[0250] The terminal block 23 is partially located within the first mounting hole 311 and abuts against the inner wall of the first mounting hole 311 formed by the sealing gasket 31. This improves the sealing performance of the seal 30. Furthermore, the terminal block 23 can also be partially located within the sealing ring 32 and abut against the inner wall of the sealing ring 32, further improving the sealing performance of the seal 30.

[0251] 24 and 25 , the housing 11 has a sidewall 103, which is formed with a first port 1111. The connector 1 further includes a rib 16, which is connected to and protrudes from the sidewall 103. The rib 16 is disposed around the first port 1111 and abuts against the sealing gasket 31. Compared to the abutment of the sidewall 103 with the sealing gasket 31, the rib 16 abuts against the sealing gasket 31 because the contact area between the rib 16 and the sealing gasket 31 is smaller. Therefore, the rib 16 more easily compresses the sealing gasket 31, causing it to deform, thereby achieving closer contact between the sealing gasket 31, the connector 1, and the compressor assembly 20, and achieving a better sealing effect.

[0252] Referring to FIG. 26 , which is an enlarged schematic diagram of the structure at point M in FIG. 25 , the rib 16 includes a connecting portion 161 connected to the side wall 103 and an abutting portion 162 away from the side wall 103 . The connecting portion 161 is connected to the abutting portion 162 . Both the connecting portion 161 and the abutting portion 162 are arranged around the first port 1111 .

[0253] In some embodiments, the width of the abutting portion 162 along the radial direction of the first port 1111 gradually decreases in the direction from the connecting portion 161 to the abutting portion 162. In the rib 16, the abutting portion 162 contacts the sealing gasket 31 on the side away from the connecting portion 161. The above design can reduce the contact area between the abutting portion 162 and the sealing gasket 31, making it easier for the abutting portion 162 to squeeze the sealing gasket 31 and compress and deform it, thereby achieving a closer contact between the sealing gasket 31 and the connector 1 and the compressor assembly 20, and improving the sealing performance. In other embodiments, the width of the abutting portion 162 along the radial direction of the first port 1111 remains unchanged in the direction from the connecting portion 161 to the abutting portion 162, thereby simplifying the manufacturing difficulty of the abutting portion 162 and reducing the manufacturing cost of the abutting portion 162.

[0254] It should be noted that, in the direction from the connecting portion 161 to the abutting portion 162 , the width of the abutting portion 162 along the radial direction of the first port 1111 may gradually increase, or first increase and then decrease, or first decrease and then increase, etc., and this is not limited.

[0255] In some embodiments, the width of the connecting portion 161 along the radial direction of the first port 1111 gradually decreases from the connecting portion 161 to the abutting portion 162. In this case, if the width of the abutting portion 162 along the radial direction of the first port 1111 gradually decreases from the connecting portion 161 to the abutting portion 162, the transition between the connecting portion 161 and the abutting portion 162 can be smoother. In other embodiments, the width of the connecting portion 161 along the radial direction of the first port 1111 remains constant from the connecting portion 161 to the abutting portion 162. This ensures a secure connection between the connecting portion 161 and the housing 11.

[0256] In the embodiment of the present application, the width of the connecting portion 161 along the radial direction of the first port 1111 may gradually increase from the connecting portion 161 to the abutting portion 162, or may first increase and then decrease, or first decrease and then increase, etc., without limitation.

[0257] The connector 1 may include one rib 16 or at least two ribs 16. If the connector 1 includes at least two ribs 16, the at least two ribs 16 are spaced apart along the radial direction of the first port 1111. Each rib 16 can compress the sealing gasket 31, thereby achieving closer contact between the sealing gasket 31 and the connector 1 and the compressor assembly 20 at the rib 16. That is, providing at least two ribs 16 can achieve closer contact between the sealing gasket 31 and the connector 1 and the compressor assembly 20 at multiple locations, thereby improving sealing performance.

[0258] In some embodiments, if the connector 1 includes at least two ribs 16, as shown in FIG26 , the height of each rib 16 protruding from the sidewall 103 can be approximately equal. This allows for a rough estimate of the extent to which each rib 16 has compresses the gasket 31 when the outermost rib 16 compresses the gasket 31, simplifying the connection and sealing process. In other embodiments, as shown in FIG27 , which is an enlarged schematic diagram of an alternative structure at position M in FIG25 , if the connector 1 includes at least two ribs 16, the height of each rib 16 protruding from the sidewall 103 can gradually decrease along the radial direction of the first port 1111 and from the outside to the inside. This allows the outermost rib 16 to exert the greatest pressure on the gasket 31, resulting in optimal sealing performance. The innermost rib 16 exerts a gradually decreasing pressure on the gasket 31, resulting in a gradually weakened sealing performance. This reduces the force required to connect the connector 1 and the compressor assembly 20, easing connection difficulty and ensuring a secure seal between the connector 1 and the compressor assembly 20.

[0259] It should be noted that if the connector 1 includes at least two ribs 16 , the height of each rib 16 protruding from the side wall 103 along the radial direction of the first port 1111 and from the outside to the inside may also alternately decrease and increase, and this is not limited.

[0260] If the connector 1 includes at least two ribs 16 , each rib 16 may include the aforementioned connecting portion 161 and abutting portion 162 , which is not limited thereto.

[0261] The rib 16 and the housing 11 can be integrally formed to simplify the assembly process of the connector 1 and improve assembly efficiency. The rib 16 and the housing 11 can also be detachably connected, for example, by snapping, bonding, or the like, to facilitate replacement of the rib 16 and reduce replacement costs.

[0262] Referring to Figures 28 to 31 , Figure 28 is a schematic top view of the compressor assembly 2 shown in Figure 23 , Figure 29 is a schematic cross-sectional view taken along the EE direction in Figure 28 , and Figure 31 is an exploded cross-sectional view of the connector 1 and seal 30 in Figure 29 . Figure 31 is an exploded view of the compressor assembly 2 shown in Figure 23 . The connector 1 further includes a first connector 13 , which is located on a side outside the housing 11 and mounted on the housing 11 . The compressor assembly 20 further includes a second connector 22 mounted on the casing 24 , with at least a portion of the second connector 22 located outside the casing 24 . The sealing gasket 31 is formed with a second mounting hole 312 , through which the second connector 22 passes to connect with the first connector 13 . The provision of the second mounting hole 312 allows the seal 30 to be positioned on the compressor assembly 20 , thereby improving sealing performance.

[0263] The second connector 22 passes through the second mounting hole 312 to connect with the first connector 13. The second connector 22 can be connected to the locking member 40 after passing through the second mounting hole 312 and the connecting hole 133 formed by the first connector 13. In this way, the connector 1 and the compressor assembly 20 can be connected and fixed. The second connector 22 and the locking member 40 can be connected by threads. For example, the locking member 40 includes a nut, and the second connector 22 is provided with threads. The second connector 22 passes through the second mounting hole 312 and the connecting hole 133 and is threadedly connected and fixed with the nut. By tightening the nut, the distance between the compressor assembly 20 and the connector 1 can be shortened. Of course, the second connector 22 extending into the connecting hole 133 can also be connected to the inner wall of the connecting hole 133 by means of snap-fitting or the like, and this is not limited to this.

[0264] In some embodiments, the connector 1 may include a first connector 13, and the compressor assembly 20 may include a second connector 22, wherein the first connector 13 is connected to the second connector 22. In this way, the connection process between the connector 1 and the compressor assembly 20 can be simplified, the connection efficiency can be improved, and the volume of the connector 1 can be reduced.

[0265] It should be noted that the connector 1 and the compressor assembly 20 are connected via a first connector 13 and a second connector 22, and the first connector 13 is located on a side outside the housing 11. Therefore, when the connector 1 is connected to the compressor assembly 20, the sealing gasket 31 may rebound due to less force on the side of the first port 1111 away from the first connector 13, causing the side of the housing 11 away from the first connector 13 to tilt up, affecting the sealing performance of the sealing gasket 31. At this time, because the sealing member 30 also includes a sealing ring 32, when the housing 11 tilts up, the sealing ring 32 can be deformed on the side of the housing 11 away from the first connector 13 to be tightly connected to the housing 11, thereby improving the problem of weakened sealing performance of the sealing gasket 31 caused by the tilting of the housing 11.

[0266] In other exemplary embodiments, the connector 1 includes at least two first connectors 13, which are spaced apart circumferentially around the housing 11. The compressor assembly 20 includes at least two second connectors 22, which are connected one-to-one with the first connectors 13. This allows the connector 1 to be connected to the compressor assembly 20 at multiple locations around the housing 11, improving the problem of the connector 1 warping on the side opposite to the compressor assembly 20 when the connector 1 and the compressor assembly 20 are fixed on one side.

[0267] The at least two first connectors 13 can be arranged non-center-symmetrically or center-symmetrically about the circumference of the housing 11. If the at least two first connectors 13 are arranged non-center-symmetrically about the circumference of the housing 11, when the connector 1 is connected to the compressor assembly 20, only in one case can each first connector 13 and each second connector 22 achieve a one-to-one connection, thereby achieving a fool-proof effect. If the at least two first connectors 13 are arranged center-symmetrically about the circumference of the housing 11, the structure of the connector 1 can be more regular.

[0268] Next, the connector 1 will be further described.

[0269] Referring to Figures 29 to 33, Figure 32 is an exploded schematic diagram of the connector 1 in the compressor assembly 2 shown in Figure 23, and Figure 33 is an overhead schematic diagram of the connector 1 in the compressor assembly 2 shown in Figure 23. The connector terminal 12 can be any terminal, and the compressor terminal 21 can be any terminal, as long as the compressor terminal 21 and the connector terminal 12 can be electrically connected.

[0270] For example, one of the connector terminal 12 and the compressor terminal 21 can be a male terminal, and the other can be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, and the compressor terminal 21 is a male terminal. The connector terminal 12 is formed with a socket, and at least a portion of the compressor terminal 21 is inserted into the socket and electrically connected to the connector terminal 12. In other words, when the connector terminal 12 and the compressor terminal 21 are connected, at least a portion of the compressor terminal 21 is surrounded by the connector terminal 12, which can improve the connection reliability between the connector terminal 12 and the compressor terminal 21.

[0271] The housing 11 defines a first chamber 1117, which is located within and communicates with the first port 1111. The connector terminal 12 is located within the first chamber 1117. This allows the compressor terminal 21 to extend into the first chamber 1117 through the first port 1111 and electrically connect to the connector terminal 12. The provision of the first chamber 1117 facilitates positioning the connector terminal 12 within the housing 11.

[0272] The connector 1 may include a plurality of connector terminals 12, and the housing 11 may be formed with a plurality of first cavities 1117, with each connector terminal 12 correspondingly located in each first cavity 1117. For example, the connector 1 may include two connector terminals 12, and the housing 11 may be formed with two first cavities 1117; or the connector 1 may include three connector terminals 12, and the housing 11 may be formed with three first cavities 1117, and so on, without limitation.

[0273] It can be understood that when the connector 1 includes multiple connector terminals 12 , the compressor assembly 20 includes multiple compressor terminals 21 equal in number to the multiple connector terminals 12 , and each compressor terminal 21 is electrically connected to each connector terminal 12 in a one-to-one correspondence.

[0274] Housing 11 defines a second chamber 1118, which extends from sidewall 103 toward the other side of housing 11. Second chamber 1118 forms a first port 1111 on sidewall 103. When connector 1 is connected to compressor assembly 20, second chamber 1118 is closer to compressor assembly 20 than first chamber 1117. The provision of second chamber 1118 reduces the mating area between connector 1 and compressor assembly 20, lowering the precision design requirements for connector 1's mating surface.

[0275] Observing along the first port 1111, the cross-sectional profiles of all first cavities 1117 are located within the cross-sectional profile of the second cavity 1118. Thus, when the connector 1 includes multiple connector terminals 12 and the compressor assembly 20 includes multiple compressor terminals 21, when the compressor terminals 21 are connected to the connector terminals 12, all compressor terminals 21 can pass through the second cavity 1118 and then reach the corresponding first cavity 1117, thereby achieving electrical connection with the corresponding connector terminals 12.

[0276] The sealing ring 32 may be located in the second chamber 1118 of the housing 11 and fit against the inner wall of the second chamber 1118 . The terminal block 23 may be located in the second chamber 1118 .

[0277] In some embodiments, the housing 11 may include a first housing portion 111 and a second housing portion 112. The first housing portion 111 is formed with a first port 1111, a first chamber 1117, and a second port 1114 communicating with the first chamber 1117. The connector terminal 12 is mounted on the first housing portion 111 via the second port 1114, and the second housing portion 112 is connected to the first housing portion 111. Disassembling the housing 11 into the first housing portion 111 and the second housing portion 112 facilitates assembly of the connector terminal 12. The first housing portion 111 may be provided with a second chamber 1118.

[0278] The first housing portion 111 has a higher heat resistance than the second housing portion 112. Compared to the second housing portion 112, the first housing portion 111 is less likely to deform under high temperature conditions. Thus, by disposing the first port 1111 in the first housing portion 111, when the connector 1 is connected to the compressor assembly 20, the first housing portion 111 is close to the compressor assembly 20. The first housing portion 111 has a higher heat resistance, which can prevent the internal connector terminals 12 from being softened by high temperatures, thereby extending the service life of the connector terminals 12.

[0279] The seal 30 is located between the first housing portion 111 and the casing 24 of the compressor assembly 20. As a result, even if heat from the surface of the compressor assembly 20 is transferred to the seal 30 and the first housing portion 111, the first housing portion 111 is unlikely to deform, thereby providing a stable support for the seal 30, ensuring the sealing performance between the compressor assembly 20 and the connector 1, while also ensuring a stable connection between the compressor assembly 20 and the connector 1.

[0280] The first housing portion 111 can be made of a highly heat-resistant material. For example, the first housing portion 111 can 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, a high-temperature and fire-resistant insulation material that prevents softening of the connector terminals 12 during operation.

[0281] The second housing portion 112 can cover the second port 1114 and the connector terminal 12. The provision of the second port 1114 facilitates installation of the connector terminal 12 within the housing 11. The second housing portion 112 covers the second port 1114 and the connector terminal 12, allowing the connector terminal 12 and the compressor terminal 21 to be enclosed by the housing 11 of the connector 1 when connected, thereby preventing the presence of refrigerant near the connector terminal 12 and the compressor terminal 21 from sparking when connected. The first housing portion 111 can include a sidewall 103.

[0282] 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, so that the injection-molded housing portion and the first housing portion 111 are at least an integrally-molded structure. Specifically, after the first housing portion 111 is molded, at least the first housing portion 111 is placed in a mold to form a cavity for molding the injection-molded housing portion, and then a molding compound is injected into the cavity to obtain the injection-molded housing portion.

[0283] The glue-potted housing portion is formed by a glue-potting process, and the glue-potted housing portion is connected to the first housing portion 111. Therefore, the glue-potted housing portion and the first housing portion 111 are at least an integrally molded structure formed by glue-potting. Specifically, the first housing portion 111 is formed with a molding groove, and at least the molding groove participates in constructing the glue-potted housing portion. Then, molding material is injected into the molding groove to obtain the glue-potted housing portion.

[0284] In summary, whether the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, the second housing portion 112 and the first housing portion 111 can be integrally formed. Compared to independently molding the second housing portion 112 and the first housing portion 111 and then assembling them, the tightness of the connection between the second housing portion 112 and the first housing portion 111 can be improved, as can the sealing between the second housing portion 112 and the first housing portion 111. The second housing portion 112 and the first housing portion 111 of the connector 1 are sealed, and when the connector 1 is connected to the compressor assembly 20, the first housing portion 111 and the surface of the compressor assembly 20 are sealed due to the presence of the seal 30. In this way, the overall sealing of the connector 1 can be improved.

[0285] The second housing portion 112 can be made of a sealant shell, which provides excellent sealing performance. The second housing portion 112 can be elastic or non-elastic, allowing for flexible design based on actual needs. In the embodiment of the present application, the second housing portion 112 can be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing properties. The second housing portion 112 can be made of plastic or silicone, without limitation.

[0286] To enhance the connection reliability between the second housing portion 112 and the first housing portion 111, one of the second housing portion 112 and the first housing portion 111 can be provided with a hook 1121, and the other can be provided with a slot 1115 that matches the hook 1121, with the hook 1121 located within the slot 1115. The second housing portion 112 and the first housing portion 111 can be hooked together via the hook 1121, preventing them from easily disengaging. It is understood that the second housing portion 112 can be provided with the hook 1121 and the first housing portion 111 can be provided with the slot 1115; alternatively, the second housing portion 112 can be provided with the slot and the first housing portion 111 can be provided with the hook, without limitation.

[0287] 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 1.

[0288] Connector 1 also includes a cover member that covers second port 1114, and second housing portion 112 covers the cover member. The cover member prevents moisture, dust, and other impurities from entering first housing portion 111 and affecting the performance of connector terminal 12. Furthermore, when second housing portion 112 includes an injection-molded housing portion or a potted housing portion, the cover member prevents the molding compound of second housing portion 112 from passing through second port 1114 and reaching connector terminal 12, thereby encasing connector terminal 12 and ensuring effective electrical connection between connector terminal 12 and compressor terminal 21.

[0289] The connector terminal 12 and the cover member may abut 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, thereby preventing the connector terminal 12 and the compressor terminal 21 from being damaged by forced insertion.

[0290] 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 .

[0291] One of the cover plate 14 and the first housing portion 111 can be provided with a limiting protrusion 141, and the other can be provided with a limiting groove 1116, with the limiting protrusion 141 located within the limiting groove 1116. The provision of the limiting protrusion 141 and the limiting groove 1116 can facilitate positioning of the cover plate 14 and the first housing portion 111 during assembly, thereby improving assembly efficiency of the cover plate 14 and the first housing portion 111. It is 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; alternatively, 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, without limitation. 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 the limiting groove 1116.

[0292] If the housing 11 is formed with a plurality of second ports 1114 , the cover 14 covers all the second ports 1114 .

[0293] The connector 1 also includes a connecting wire 15, which is electrically connected to the connector terminal 12 and is used to enable signal interaction between the compressor assembly 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 portion 112 to improve the connection reliability between the connecting wire 15 and the connector terminal 12 and improve the sealing of the connector 1. Specifically, when the second shell portion 112 includes an injection molding shell portion and / or a glue-filling shell portion, the second shell portion 112 can directly wrap the end of the connecting wire 15 connected to the connector terminal 12 during injection molding and / or glue-filling. If the connector 1 includes multiple connector terminals 12, the connecting wire 15 is electrically connected to the multiple connector terminals 12.

[0294] Thirdly, referring to FIG6 , an embodiment of the present application provides a HVAC system, comprising the aforementioned connector 1 and a compressor assembly 2 connected to the connector 1. The HVAC system may include an air conditioner, a multi-split unit, a heat pump, or other heating or cooling system, which is not limited in the present embodiment.

[0295] 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.

[0296] In a fourth 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:

[0297] Step S02 , providing a housing 11 and a connector terminal 12 ; wherein the housing 11 has a first cavity 1117 , the first cavity 1117 has a first port 1111 and a second port 1114 , and the housing 11 is elastic.

[0298] In step S04 , the connector terminal 12 is inserted into the first cavity 1117 through the first port 1111 and is located in the first cavity 1117 .

[0299] In the embodiment of the present application, the housing 11 of the connector 1 is designed to be elastic as a whole. In this way, the connector terminal 12 can extend from the first port 1111 of the housing 11 into the first chamber 1117 thereof to achieve assembly between the connector terminal 12 and the housing 11. That is, in the embodiment of the present application, the connector terminal 12 and the housing 11 can be independently molded and then assembled. Compared with the related art in which the connector terminal and the housing are integrally molded through a process such as injection molding, this facilitates the disassembly, assembly, and replacement of the connector terminal 12 and the housing 11. When the connector 1 is damaged, compared with replacing the entire connector, only the damaged connector terminal 12 or the housing 11 can be replaced, thereby reducing maintenance costs. In addition, the housing 11 is elastic as a whole. When the compressor terminal 21 and the connector terminal 12 are plugged into each other, the housing 11 can also undergo a certain deformation to adapt to the tolerance of the compressor terminal 21, thereby reducing the precision requirements of the connector 1 in the embodiment of the present application and reducing the manufacturing cost of the connector 1.

[0300] It should be noted that, since the housing 11 is elastic, to prevent deformation of the housing 11 that could cause misalignment between the connector terminals 12 and the compressor terminals 21, when the connector 1 and the compressor terminals 21 are mated, the housing 11 can be squeezed to grip the connector terminals 12 to achieve mating between the connector terminals 12 and the compressor terminals 21. In other words, when the connector 1 and the compressor terminals 21 are mated, force can be applied directly to the connector terminals 12 to control the direction of the connector terminals 12.

[0301] 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.

[0302] 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.
