[0059] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0060] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0061] Embodiment 1

[0062] See also Figures 1 to 3 The embodiment of the present application provides a connector 10, which includes a housing 11 and a connector terminal 12. The housing 11 includes a first housing portion 111 and a second housing portion 112 connected to the first housing portion 111. The heat resistance of the first housing portion 111 is higher than that of the second housing portion 112. The first housing portion 111 is formed with a first port 1111 and a second port 1114. The connector terminal 12 is installed in the first housing portion 111 through the second port 1114. Figure 4 and Figure 5 The connector terminal 12 is used to be electrically connected to the compressor terminal 21 extending through the first port 1111 .

[0063] In the embodiment of the present application, the housing 11 is split into a first housing portion 111 and a second housing portion 112, which is convenient for assembling the connector terminal 12. The heat resistance of the first housing portion 111 is higher than that of the second housing portion 112. Compared with the second housing portion 112, the first housing portion 111 is less likely to deform under high temperature conditions. Thus, the first port 1111 is disposed in the first housing portion 111. When the connector 10 is connected to the compressor 20, the first housing portion 111 is close to the compressor 20. The first housing portion 111 has a high heat resistance, which can prevent the internal connector terminal 12 from being softened by high temperature, thereby extending the service life of the connector terminal 12.

[0064] The first housing portion 111 may be made of a high heat-resistant material, for example, the first housing portion 111 may include at least one of PBT (poly butylene terephthalate) and GF (glass fiber). In the embodiment of the present application, the first housing portion 111 is made of PBT+30% GF, which is a high temperature resistant and fireproof material, and can prevent the connector terminal 12 from softening during operation.

[0065] Combination Figure 3 , the second housing portion 112 can cover the second port 1114 and the connector terminal 12. The second port 1114 is provided to facilitate the installation of the connector terminal 12 in the housing 11, and the second housing portion 112 covers the second port 1114 and the connector terminal 12, so that when the connector terminal 12 and the compressor terminal 21 are connected, both are wrapped by the housing 11 of the connector 10, avoiding the presence of refrigerant near the two and the ignition problem when the connector terminal 12 and the compressor terminal 21 are connected.

[0066] The second housing portion 112 may include an injection-molded housing portion connected to the first housing portion 111, and / or the second housing portion 112 may include a glue-filled housing portion connected to the first housing portion 111. The injection-molded housing portion is formed by an injection molding process, and the injection-molded housing portion is connected to the first housing portion 111, and the injection-molded housing portion is at least an integrally-molded structure with the first housing portion 111. Specifically, after the first housing portion 111 is molded, at least the first housing portion 111 is placed in a mold to participate in constructing a cavity for molding the injection-molded housing portion, and then a molding material is injected into the cavity to obtain the injection-molded housing portion.

[0067] The glue-filled housing portion is formed by a glue-filling process, and the glue-filled housing portion is connected to the first housing portion 111, so the glue-filled housing portion is at least an integrally molded structure with the first housing portion 111. Specifically, the first housing portion 111 is formed with a molding groove, and at least the molding groove participates in constructing a glue-filling groove for molding the glue-filled housing portion, and then the molding material is injected into the glue-filling groove to obtain the glue-filled housing portion.

[0068] In summary, whether the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, the second housing portion 112 and the first housing portion 111 can be formed as an integral structure, which can improve the tightness of the connection between the second housing portion 112 and the first housing portion 111, and improve the sealing between the second housing portion 112 and the first housing portion 111, compared with the second housing portion 112 and the first housing portion 111 being formed independently and then assembled. The second housing portion 112 of the connector 10 is sealed to the first housing portion 111, and when the connector 10 is connected to the compressor 20, the first housing portion 111 and the surface of the compressor 20 are sealed due to the presence of the seal 13, so that the overall sealing of the connector 10 can be improved.

[0069] The second shell part 112 may be made of a sealing rubber shell, which has a high sealing performance. The second shell part 112 may be elastic or inelastic, and may be flexibly designed according to actual needs. In the embodiment of the present application, the second shell part 112 may be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing performance. The second shell part 112 may be made of plastic or silicone, which is not limited.

[0070] In order to improve the connection reliability between the second housing part 112 and the first housing part 111, one of the second housing part 112 and the first housing part 111 may be provided with a hook 1121, and the other may be provided with a slot 1115 adapted to the hook 1121, and the hook 1121 is located in the slot 1115. The second housing part 112 and the first housing part 111 can be hooked by the hook 1121 and are not easy to be separated. It can be understood that the second housing part 112 may be provided with a hook 1121, and the first housing part 111 may be provided with a slot 1115; or the second housing part 112 may be provided with a slot 1115, and the first housing part 111 may be provided with a hook 1121, and this is not limited.

[0071] It is understandable that the second housing portion 112 can be integrally formed as an injection-molded housing portion, or the second housing portion 112 can be integrally formed as a glue-potted housing portion, so as to simplify the processing technology of the second housing portion 112 and reduce the manufacturing cost of the connector 10 .

[0072] See also Figure 3 and Figure 5The connector 10 further includes a sealing member 13, which is located on one side of the first port 1111 of the first housing portion 111 and is disposed around the first port 1111, and is connected to the first housing portion 111. The sealing member 13 is disposed on the first housing portion 111, so that even if the heat on the surface of the compressor 20 is transferred to the sealing member 13 and the first housing portion 111, the first housing portion 111 is not easily deformed, and thus can provide a stable support effect for the sealing member 13, thereby ensuring the sealing performance between the compressor 20 and the connector 10, and at the same time ensuring the stability of the connection between the compressor 20 and the connector 10.

[0073] It is understandable that the two opposite sides of the seal 13 can respectively abut the surface of the compressor 20 and the first housing portion 111 to achieve sealing between the surface of the compressor 20 and the first housing portion 111. In an exemplary solution, the seal 13 can be disposed on the port surface where the first port 1111 of the first housing portion 111 is located. At this time, in order to achieve a reliable connection between the seal 13 and the first housing portion 111, the seal 13 and the first housing portion 111 can be connected by means of adhesives or the like to prevent the seal 13 from falling off.

[0074] In another exemplary embodiment, an annular groove 1113 may be provided on one side of the first port 1111 of the first shell portion 111, and the annular groove 1113 is arranged around the first port 1111. Part of the seal 13 may be located in the annular groove 1113. The setting of the annular groove 1113 can, on the one hand, locate the installation position of the seal 13 on the first shell portion 111, thereby speeding up the assembly speed between the seal 13 and the first shell portion 111; on the other hand, it can constrain the seal 13 and accommodate the deformation of the seal 13 caused by extrusion so that it is not easy to move.

[0075] See also Figure 3 , the portion of the seal 13 located in the annular groove 1113 may be: the seal 13 includes a first portion 131 and a second portion 132 distributed in the depth direction of the annular groove 1113, the first portion 131 may be located in the annular groove 1113, and the second portion 132 may be located outside the annular groove 1113. The second portion 132 located outside the annular groove 1113 may be deformed when the connector 10 is connected to the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.

[0076] It is understandable that the annular groove 1113 may be connected to the first port 1111, or may not be connected to the first port 1111. In the embodiment of the present application, the annular groove 1113 is not connected to the first port 1111, which can prevent the seal 13 from deforming toward the first port 1111 when it is squeezed and deformed, thereby affecting the installation stability of the seal 13. It should be noted that the seal 13 can be installed in the annular groove 1113 by snapping, or by bonding, etc., and this is not limited.

[0077] The seal 13 may be any device with sealing performance, such as a sealing ring, etc. In the embodiment of the present application, the seal 13 is a device with elasticity and high heat resistance, wherein the seal 13 has elasticity, so that when the connector 10 is connected to the compressor 20, the seal 13 can be in a compressed state to improve the tightness of the connection between the connector 10 and the compressor 20; and the seal 13 has high heat resistance, which can prevent the seal 13 from being damaged by the surface heat of the compressor 20, and can improve the service life of the seal 13. Specifically, the seal 13 can be a silicone rubber seal, which has low cost and is elastic and highly heat-resistant.

[0078] Combination Figure 3 The connector 10 also includes a cover, which covers the second port 1114, and the second housing portion 112 covers the cover. Under the cover, impurities such as water vapor and dust can be prevented from entering the first housing portion 111, which would affect the performance of the connector terminal 12. When the second housing portion 112 includes an injection-molded housing portion or a glue-filled housing portion, under the cover, the molding material of the second housing portion 112 will not pass through the second port 1114 to reach the connector terminal 12, and wrap the connector terminal 12, thereby ensuring effective electrical connection between the connector terminal 12 and the compressor terminal 21.

[0079] The connector terminal 12 and the cover member may be in contact with each other or have a gap therebetween. Figure 3 If there is a gap between the connector terminal 12 and the cover member, the connector terminal 12 can be deformed toward the gap when plugged into the compressor terminal 21 to avoid damage to the connector terminal 12 and the compressor terminal 21 due to hard insertion.

[0080] 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 .

[0081] One of the cover plate 14 and the first housing portion 111 may be provided with a limiting protrusion 141, and the other may be provided with a limiting groove 1116, and the limiting protrusion 141 is located in the limiting groove 1116. The provision of the limiting protrusion 141 and the limiting groove 1116 can position the cover plate 14 and the first housing portion 111 when they are assembled, which is conducive to improving the assembly efficiency of the cover plate 14 and the first housing portion 111. It can be understood that the limiting protrusion 141 can be provided on the cover plate 14, and the limiting groove 1116 can be provided on the first housing portion 111; or, the limiting groove 1116 can be provided on the cover plate 14, and the limiting protrusion 141 can be provided on the first housing portion 111, and this is not limited. In the embodiment of the present application, a limiting protrusion 141 is provided on the cover plate 14, and a limiting groove 1116 is provided on the first shell portion 111. Since the cover plate 14 is relatively thin, providing the limiting protrusion 141 on the cover plate 14 is more conducive to improving the structural strength of the cover plate 14 than providing the limiting groove 1116.

[0082] See also Figure 5 , the first housing portion 111 is formed with a first chamber 1117 for accommodating the connector terminal 12, and the first chamber 1117 may be formed with a second port 1114. The connector 10 may include at least two connector terminals 12, and the first housing portion 111 is formed with at least two first chambers 1117 equal in number to the at least two connector terminals 12, and each connector terminal 12 is mounted in each first chamber 1117 in a one-to-one correspondence. For example, the connector 10 includes two connector terminals 12, and the first housing portion 111 is formed with two first chambers 1117; or, the connector 10 includes three connector terminals 12, and the first housing portion 111 is formed with three first chambers 1117, and so on, without limitation.

[0083] It should be noted that when at least two first chambers 1117 are formed on the first housing portion 111 , the first housing portion 111 has at least two second ports 1114 , and the cover plate 14 covers all the second ports 1114 .

[0084] It is understandable that when the connector 10 includes at least two connector terminals 12, the compressor 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. Due to factors such as manufacturing errors, the compressor terminals 21 of the compressor 20 inevitably have tolerances, for example, the thickness of the compressor terminals 21, the inclination of the compressor terminals 21, the spacing between two adjacent compressor terminals 21, etc. have certain tolerances. In order to enable the compressor terminals 21 to be effectively electrically connected to the connector terminals 12 even when there are tolerances, the connector terminals 12 can move in the first chamber 1117 along the first direction to adapt to the tolerance of the compressor terminals 21.

[0085] Specifically, the connector terminal 12 may have a plugging surface 121 and a back surface 122 opposite to the plugging surface 121, wherein 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 be 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 of the compressor terminal 21 and the connector terminal 12. The first direction may be perpendicular to the plugging direction of the compressor terminal 21 and the connector terminal 12. The connector terminal 12 moves in the first chamber 1117 along the first direction, which may be: along the first direction, there is a gap between the back surface 122 and the inner wall surface of the first chamber 1117, so that when the compressor terminal 21 is inserted into the first chamber 1117 to contact the connector terminal 12, the connector terminal 12 can be pushed to deform toward the gap to adapt to the tolerance of the compressor terminal 21.

[0086] Furthermore, in the first direction, the gap G between the back surface 122 and the inner wall surface of the first chamber 1117 is 1 Satisfy: 0.1mm≤G 1 ≤2mm. By reasonably limiting the gap G1 between the back surface 122 and the inner wall surface of the first chamber 1117 in the first direction, it is possible to avoid space waste caused by too large a gap and damage caused by hard insertion of the compressor terminal 21 and the connector terminal 12 due to insufficient gap. Optionally, G 1 It can be 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, etc., without limitation.

[0087] One of the connector terminal 12 and the compressor terminal 21 may be a male terminal, and the other may be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, the compressor terminal 21 is a male terminal, the connector terminal 12 is formed with a plug hole 123, and at least a portion of the compressor terminal 21 is inserted into the plug hole 123 and is electrically connected to the connector terminal 12.

[0088] Specifically, in an exemplary embodiment, see Figure 6The connector terminal 12 includes a first main board 124, two first bent plates 125 connected to the first main board 124, and two second bent plates 126 connected to the first main board 124. The first main board 124 extends along the above-mentioned plug-in direction. 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 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 facing The second bending plate 126 is bent and extended in a direction away from the first main board 124; one end of each second bending plate 126 is respectively connected to one end of each first bending plate 125 away from the first main board 124, and the other end of each second bending plate 126 is bent and extended in a direction close to each other and close to the first main board 124. Each second bending plate 126 is spaced apart from the first main board 124 to form a first plug hole 1231. The two second bending plates 126 are spaced apart in a direction perpendicular to the plugging direction and parallel to the board surface of the first main board 124 to form a second plug hole 1232. The plug hole 123 includes a first plug hole 1231 and a second plug hole 1232. At this time, the structure of the connector terminal 12 is relatively stable and not easy to deform, and the first plug hole 1231 and the second plug hole 1232 can both be connected to the compressor terminal 21, and the connection is more reliable. The plug-in surface 121 of the connector terminal 12 may include a surface of the first main board 124 close to the two first bending plates 125 and a surface of the two second bending plates 126 close to each other. The back surface 122 of the connector terminal 12 may be a surface of the first main board 124 away from the two first bending plates 125, and the first direction may be perpendicular to the board surface of the first main board 124.

[0089] In this exemplary embodiment, see Figure 6 and Figure 7 The connector 10 includes three connector terminals 12, namely a first connector terminal 12a, a second connector terminal 12b and a third connector terminal 12c, and the first main boards 124 of the three connector terminals 12 are arranged at an angle to each other. Specifically, along the clockwise direction, the angle θ between the first main board 124 of the first connector terminal 12a and the first main board 124 of the second connector terminal 12b is 1 The angle θ between the first main board 124 of the first connector terminal 12a and the first main board 124 of the third connector terminal 12c is greater than or equal to 20° and less than or equal to 40°. 2Greater than or equal to 50° and less than or equal to 70°. It is understood that the orientation of the compressor terminal 21 corresponds to the orientation of the corresponding connector terminal 12. Through the above arrangement, a feasible plug-in method can be provided for the three connector terminals 12 and the three compressor terminals 21, that is, a matching method can be provided for the three connector terminals 12 and the three compressor terminals 21, which can avoid the problem of wrong plug-in. It is understood that the angle θ between the first main board 124 of the first connector terminal 12a and the first main board 124 of the second connector terminal 12b is 1 The angle θ 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 20°, 25°, 30°, 35°, 40°, etc. 2 It can be 50°, 55°, 60°, 65°, 70° and so on.

[0090] In this exemplary embodiment, see Figure 8 and Fig. 9 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 roughly a sheet-like structure extending along the plug-in direction, and the second plug-in portion 212 may be roughly a columnar structure extending along the plug-in direction, which can improve the structural strength of the compressor terminal 21 and prevent deformation. Along the plug-in direction, the cross-sectional profile of the first plug-in portion 211 may be roughly a narrow square, and the cross-sectional profile of the second plug-in portion 212 may be roughly a circle, which is not limited. 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 20.

[0091] In this exemplary embodiment, 0.2 mm ≤ G 1 ≤2mm. Further, 0.4mm≤G 1 ≤1mm. For example, G 1 It can be 0.4mm, 0.5mm, 0.7mm, 0.9mm, 1mm, etc., without limitation.

[0092] Specifically, in another exemplary embodiment, see Figures 10 to 16, the connector terminal 12 includes an electrical connection portion 127 for electrically connecting to the compressor terminal 21, the electrical connection portion 127 is formed with a plug hole 123, and the electrical connection portion 127 includes an introduction portion 1271 and a mounting portion 1272 distributed along the plug-in direction, the introduction portion 1271 is closer to the first port 1111 than the mounting portion 1272, that is, when the compressor terminal 21 is plugged with the connector terminal 12, it first enters the introduction portion 1271 and then enters the mounting portion 1272. Among them, along the direction from the introduction portion 1271 to the mounting portion 1272, the inner diameter of the introduction portion 1271 gradually decreases and then gradually increases. In this way, when the compressor terminal 21 is connected to the introduction portion 1271 of the connector terminal 12, the compressor terminal 21 will be constrained by the small diameter of the introduction portion 1271, which can avoid the risk of mismatching between the compressor 20 and the connector 10 and causing misplugging. When the compressor terminal 21 is connected to the mounting portion 1272 of the connector terminal 12, the large diameter of the mounting portion 1272 can speed up the installation convenience of the compressor terminal 21 and improve the installation efficiency. In the direction from the introduction portion 1271 to the mounting portion 1272, the inner diameter of the introduction portion 1271 first gradually decreases and then gradually increases. The inner diameter of the introduction portion 1271 can change smoothly, improving the smoothness of the connection between the compressor terminal 21 and the connector terminal 12.

[0093] In this exemplary embodiment, the compressor terminal 21 can be roughly a columnar structure extending along the plugging direction to simplify the structure of the compressor terminal 21 and reduce the manufacturing cost. In the plugging direction, the cross-sectional profile of the compressor terminal 21 can be roughly circular, square, etc., without limitation.

[0094] In this exemplary solution, at least one notch 1273 may be provided on the connector terminal 12, and the notch 1273 extends along the hole axis direction of the plug hole 123 and penetrates one end of the connector terminal 12 close to the first port 1111, so that when the compressor terminal 21 is initially inserted into the connector terminal 12, due to the provision of the notch 1273, the connector terminal 12 is easily deformed and can adapt to the tolerance of the compressor terminal 21, for example, the thickness, inclination tolerance, etc. of the compressor terminal 21. The notch 1273 may be provided on the electrical connection portion 127.

[0095] In this exemplary embodiment, 0.1 mm ≤ G 1 ≤1mm. Further, 0.1mm≤G 1 ≤0.8mm. For example, G 1 It can be 0.1mm, 0.3mm, 0.5mm, 0.7mm, 0.8mm, etc., without limitation.

[0096] 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 first port 1111 than the first chamber 1117. Along the plug-in direction, the cross-sectional profile of the second chamber 1118 is larger than the cross-sectional profiles of all the first chambers 1117. Along the plug-in direction, the cross-sectional profiles of all the first chambers 1117 are located within the cross-sectional profile of the second chamber 1118. In this way, when the connector 10 includes at least two connector terminals 12 and the compressor 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 reach the corresponding first chamber 1117 to achieve electrical connection with the corresponding connector terminals 12. For further information, see Figure 8 , Fig. 9 and Fig.14 The compressor 20 may include a terminal seat 23 for fixing the compressor terminal 21, and the terminal seat 23 protrudes relative to the compressor body. When the compressor terminal 21 is connected to the connector terminal 12, the terminal seat 23 may be located in the second chamber 1118.

[0097] See again Figures 1 to 3 The connector 10 also includes a connecting wire 15, which is electrically connected to the connector terminal 12, and is used to realize signal interaction between the compressor 20 and the outside world when the connector terminal 12 is connected to the compressor terminal 21. Among them, one end of the connecting wire 15 connected to the connector terminal 12 is wrapped by the second shell part 112 to improve the connection reliability between the connecting wire 15 and the connector terminal 12, and improve the sealing of the connector 10. Specifically, when the second shell part 112 includes an injection molding shell part and / or a glue pouring shell part, the second shell part 112 can directly wrap one end of the connecting wire 15 connected to the connector terminal 12 during injection molding and / or glue pouring. If the connector 10 includes multiple connector terminals 12, the connecting wire 15 is electrically connected to the multiple connector terminals 12.

[0098] See also Figure 4 The connector 10 further includes a first connector 16, and a second connector 22 is provided on the compressor 20. The first connector 16 is connected to the second connector 22 to improve the connection reliability between the connector 10 and the compressor 20. The first connector 16 and the second connector 22 can be connected by plugging, snap-fitting, threading, etc., which is not limited.

[0099] In the embodiment of the present application, the first connecting member 16 and the second connecting member 22 are connected by a nut locking connection. Specifically, a mounting hole is formed on the first connecting member 16, and the second connecting member 22 is threadedly connected and fixed with the nut after passing through the mounting hole. By tightening the nut, the distance between the compressor 20 and the connector 10 can be shortened, thereby achieving the compression of the seal 13.

[0100] In a second aspect, the embodiment of the present application provides a HVAC system, which includes the above-mentioned connector 10 and a compressor 20 connected to the connector 10. The HVAC system may include an air conditioner, a multi-split unit, a heat pump, and other systems for heating or cooling, which are not limited in the embodiment of the present application.

[0101] The HVAC system includes a connector 10, and the specific structure of the connector 10 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.

[0102] Embodiment 2

[0103] See also Fig.12 and Fig.16 The difference between this embodiment and the first embodiment is that when the connector terminal 12 includes the electrical connection portion 127, the cover member may include a blocking portion 128, the blocking portion 128 is located on the side of the electrical connection portion 127 close to the second port 1114, the blocking portion 128 and the electrical connection portion 127 are an integrally formed structure, the second housing portion 112 covers the blocking portion 128, and the blocking portion 128 covers the second port 1114, or the blocking portion 128 covers the plug hole 123 of the electrical connection portion 127. That is, there is no need to provide a cover plate 14, and the blocking portion 128 on the connector terminal 12 can be directly used to cover the second port 1114 or the plug hole 123, so as to avoid the molding material from entering the electrical connection portion 127 from the second port 1114 or the plug hole 123 when forming the injection molding housing portion or the potting housing portion, thereby affecting the effective electrical connection between the electrical connection portion 127 and the compressor terminal 21.

[0104] 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 .

[0105] One of the electrical connection part 127 and the first housing part 111 may be formed with a convex rib 1291, and the other may be provided with a groove, and the convex rib 1291 is located in the groove. The provision of the convex rib 1291 and the groove can improve the connection reliability between the electrical connection part 127 and the first housing part 111. The convex rib 1291 may extend along the circumference of the plug hole 123, or may extend along the axial direction of the plug hole 123, which is not limited.

[0106] The connector terminal 12 may further include a lap portion 1292 that protrudes outward relative to the electrical connection portion 127 and is used to overlap the first housing portion 111 to limit the depth of the connector terminal 12 inserted into the first housing portion 111, etc.

[0107] See also Fig.12 and 15 The connector terminal 12 may further include an embedding portion 1293, which is embedded in the second housing portion 112. In this way, when the second housing portion 112 includes an injection-molded housing portion and / or a glue-filled housing portion, the embedding portion 1293 will be connected to the second housing portion 112 as a whole, which can improve the installation stability of the connector terminal 12 in the housing 11.

[0108] It should be noted that even if the embedding portion 1293 is embedded in the second housing portion 112, since the electrical connection portion 127 is located in the first cavity 1117 of the first housing portion 111, and there is a gap G between the back surface 122 of the electrical connection portion 127 and the inner wall surface of the first cavity 1117, 1 Therefore, the electrical connection portion 127 can still move toward the gap when electrically connected to the compressor terminal 21 to adapt to the tolerance of the compressor terminal 21. In addition, the second housing portion 112 uses a sealing rubber shell with a certain elasticity, which can also cause the electrical connection portion 127 to have a certain offset.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present 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.
