Modes for Carrying Out the Invention

[0057] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0058] In combination with Figures 1 to 3, according to the terminal assembly 20 for the compressor 100 according to the embodiment of the present application, the terminal assembly 20 can be arranged outside the compressor body 10, the compressor body 10 includes a terminal 11, the terminal 11 can be used to connect to a power source, and the terminal assembly 20 can be electrically connected to the terminal 11.

[0059] The terminal assembly 20 includes a terminal body 21 and a terminal block 22. The terminal body 21 has a socket 203 for pressing into the terminal stud 11. The terminal stud 22 is disposed within the terminal body 21 and fixed relative to the terminal body 21. When connecting to the compressor body 10, the terminal stud 11 of the compressor body 10 is pressed into the socket 203, and the terminal stud 11 is electrically connected to the terminal block 22 within the terminal body 21. During assembly, the terminal assembly 20 only needs to be installed on the compressor body 10. The terminal stud 11 extends into the terminal body 21 through the socket 203 and is electrically connected to the terminal stud 22 located within the terminal body 21. The terminal assembly 20 is then fixed to the compressor body 10. The terminal stud 22 can quickly and stably connect to the compressor body 10 and is disposed within the terminal body 21 so that the terminal body 21 wraps around the electrical connection point between the terminal stud 22 and the terminal stud 11, thereby improving the stability of the electrical connection.

[0060] The terminal assembly 20 for the compressor 100 according to the embodiment of the present application can improve the assembly efficiency of the compressor 100, achieve water and electricity isolation at the electrical connection points, and improve the operating stability of the compressor 100. While ensuring the reliability of the compressor 100, the integrated structure can effectively reduce the labor cost of assembling the compressor 100 for air conditioner manufacturers, etc. This solution is particularly effective for compressors 100 exported to developed countries.

[0061] The terminal block 22 in the present application can be used to connect a power source. The terminal block 22 can be pre-installed in the terminal body 21, and the terminal block 22 is adapted to the terminal body 21, and the terminal block 22 is fixed by the terminal body 21. Among them, when the terminal block 22 is used to connect a power source, two, three, four or other numbers of terminals 11 can be set according to the type of the compressor 100, and the terminal block 22 can be set to a plurality corresponding to the terminals 11. The terminal assembly 20 may include a plurality of terminal blocks 22, and for different types of compressors 100, there may be two, three or four equal numbers of terminals 11. A plurality of terminal blocks 22 are provided in the terminal body 21. In order to facilitate the docking of the terminal assembly 20 with the terminals 11, the relative positions of the plurality of terminal blocks 22 need to be defined.

[0062] As shown in Figure 2, in some embodiments of the present application, the terminal body 21 includes an inner layer structure 211 and an outer layer structure 212. The inner layer structure 211 is relatively fixedly connected to the terminal 22 to fix and protect the terminal 22. The outer layer structure 212 wraps the inner layer structure 211 and the terminal 22 to relatively fixedly connect the outer layer structure 212, the inner layer structure 211 and the terminal 22 together. The socket 203 is set on the outer layer structure 212, and the socket 203 is opposite to the terminal 22. The terminal 11 of the compressor body 10 is electrically connected to the terminal 22 through the socket 203, and the connection position of the terminal 11 and the terminal 22 is located inside the outer layer structure 212. The inner layer structure 211 can secure the connection terminals 22. When the outer layer structure 212 wraps around the inner layer structure 211, the connection terminals 22 connected to the inner layer structure 211 can be relatively fixed, preventing the connection terminals 22 from shifting or becoming loose during the docking process between the terminal assembly 20 and the compressor body 10, thereby improving the structural stability of the terminal assembly 20. In addition, wrapping the inner layer structure 211 with the outer layer structure 212 can facilitate the relative isolation of the inner layer structure 211 and the connection terminals 22 from the external environment, thereby facilitating waterproofing and dustproofing of the connection terminals 22.

[0063] In addition, in the present application, the plurality of connection terminals 22 can be positioned by the inner layer structure 211, and the inner layer structure 211 and the connection terminals 22 can be wrapped by the outer layer structure 212. This can prevent the plurality of connection terminals 22 from shifting when the outer layer structure 212 wraps the inner layer structure 211, thereby facilitating the connection between the terminal 11 of the compressor body 10 and the plurality of connection terminals 22.

[0064] 1 to 3 , the inner structure 211 has an inner cavity 2101, and the terminal 22 is disposed in the inner cavity 2101. This further improves the stability of the terminal 22 and prevents displacement of the terminal 22. The inner structure 211 may have multiple inner cavities 2101, each of which is separated from the other. The terminal 22 may be disposed in each of the multiple inner cavities 2101, and the inner structure 211 separates and insulates the multiple terminal 22 from each other.

[0065] 13 and 14 , the inner layer structure 211 is provided with a first interface 2102 and a second interface 2103, wherein the first interface 2102 and the second interface 2103 are in communication with the inner cavity 2101. The first interface 2102 is used for inserting the terminal 11, and the second interface 2103 is used for leading out the wiring harness. The first interface 2102 can be opposite the socket 203, and the terminal 11 can pass through the socket 203 and the first interface 2102 to electrically connect to the terminal 22. In addition, the inner layer structure 211 can have multiple inner cavities 2101, each of which is correspondingly provided with a first interface 2102 and a second interface 2103.

[0066] In addition, a gap can be provided between the inner surface of the inner cavity 2101 and the terminal 22. This gap is used to provide the terminal 22 with a margin for elastic deformation when the terminal 11 is pressed in, thereby facilitating the insertion and electrical connection of the terminal 11 to the terminal 22. For example, the terminal 22 can have a first spring and a second spring, which are arranged relative to each other. When the terminal 11 is pressed in, the terminal 11 is pressed between the first spring and the second spring, and the first spring and / or the second spring will undergo elastic deformation. By providing a gap between the inner surface of the inner cavity 2101 and the terminal 22, a margin can be provided for the deformation of the first spring and / or the second spring, thereby facilitating the stable fit between the terminal 11 and the terminal 22 and improving the assembly efficiency between the terminal assembly 20 and the terminal 11.

[0067] The inner layer structure 211 and the outer layer structure 212 in the present application may be formed in a variety of ways. For example, the inner layer structure 211 may be set as an integrated structure or a split structure. The inner layer structure 211 includes but is not limited to the following embodiments.

[0068] In the first embodiment, as shown in Figures 10 and 11, the inner layer structure 211 is divided into a first part 2111 and a second part 2112, and the first part 2111 and the second part 2112 are spliced ​​together, wherein after the first part 2111 and the second part 2112 are spliced ​​together, an inner cavity 2101 is constructed between the first part 2111 and the second part 2112 for accommodating the wiring terminal 22. Since the first part 2111 and the second part 2112 are in a spliced ​​form, the wiring terminal 22 can be placed between the first part 2111 and the second part 2112 during the splicing process of the first part 2111 and the second part 2112, thereby facilitating the installation and positioning of the wiring terminal 22.

[0069] The first portion 2111 and the second portion 2112 may be fixedly connected by fixing members (e.g., bolts, pins, rivets, etc.); or, the first portion 2111 and the second portion 2112 may be fixedly connected by welding, bonding, etc.; or, after the first portion 2111 and the second portion 2112 are assembled, the first portion 2111 and the second portion 2112 may be fixedly connected together using the outer layer 212. Of course, the above descriptions are merely some embodiments of the present application and are not intended to limit the scope of protection of the present application.

[0070] In a second embodiment, the inner structure 211 is integrally formed, wherein the inner structure 211 may have an inner cavity 2101, and the terminal 22 is installed in the inner cavity 2101. Integral molding can improve the structural strength of the inner structure 211, increase the service life of the terminal assembly 20, and improve the processing efficiency of the inner structure 211.

[0071] In a third embodiment, the inner layer structure 211 can be configured as an injection molded structure. In some examples, the inner layer structure 211 can be configured as a split structure, for example, the inner layer structure 211 includes a first portion 2111 and a second portion 2112, wherein the first portion 2111 and the second portion 2112 are separately injection molded and then assembled together; in other examples, the inner layer structure 211 can also be configured as an integral injection molded structure.

[0072] In the present application, the forming methods of the inner layer structure 211 and the outer layer structure 212 include but are not limited to the following embodiments.

[0073] In a first embodiment, the inner layer structure 211 and the outer layer structure 212 can be formed separately, and can be assembled after being formed separately.

[0074] In a second embodiment, after the inner layer structure 211 is injection molded, the outer layer structure 212 and the inner layer structure 211 can be secondary injection molded. This allows the inner layer structure 211 to maintain the position of the terminal 22, preventing the terminal 22 from shifting during the secondary injection molding process. It also provides a deformation margin for the terminal 22, facilitating the docking of the terminal post 11 and the terminal 22. The secondary injection molding of the outer layer structure 212 ensures that the inner layer structure 211 and the terminal 22 are waterproof and dustproof, thereby improving the stability of the terminal assembly 20.

[0075] Of course, the inner layer structure 211 and the outer layer structure 212 can also be formed separately in other ways.

[0076] In this application, the inner layer structure 211 can be a block made of PBT (polybutylene terephthalate) material mixed with a flame retardant; or the outer layer structure 212 can be a block made of PBT material mixed with a flame retardant. This ensures the flame retardancy of the terminal body 21 and improves the stability and safety of the terminal assembly 20. Alternatively, the inner layer structure 211 can be a block made of PVC (polyvinyl chloride) material or nylon material; and the outer layer structure 212 can be a block made of PVC material or nylon material.

[0077] In addition, in some embodiments of the present application, the terminal body 21 can also be configured as an integral injection molding. This can simplify the manufacturing process of the terminal body 21, and the connection terminal 22 can be arranged between the terminal body 21 during the integral molding process, thereby ensuring the waterproof and dustproof effect of the terminal assembly 20 and improving the molding efficiency and stability of the terminal assembly 20.

[0078] In addition, as shown in Figures 4 and 5, in some embodiments of the present application, the terminal assembly 20 further includes a lead wire 23, one end of which is connected to the terminal 22 and the other end of which extends out of the terminal body 21 for connecting to an external device. For example, the lead wire 23 can be used to connect to a power supply, a controller, etc. This application mainly uses the example of using the lead wire 23 to connect to a power supply to power the compressor 100. A sealing structure can be formed between the lead wire 23 and the outer layer structure 212 to improve the waterproof and dustproof effect of the terminal 22. For example, the outer layer structure 212 can be injection molded, and when the outer layer structure 212 is injection molded, the lead wire 23 is wrapped and fixed to the outer layer structure 212, thereby improving the sealing between the lead wire 23 and the terminal body 21. The specifications of the lead wire 23 can be adjusted according to the current size, and the conductor cross-section of the lead wire 23 can be set to be no less than 4 square millimeters.

[0079] In combination with the foregoing, the manufacturing method of the terminal assembly 20 of the present application may include: connecting the terminal 22 with the lead wire 23; making an inner layer structure 211 having an inner cavity 2101, installing the terminal 22 in the inner cavity 2101, and extending the lead wire 23; positioning the inner layer structure 211 with the terminal 22 installed in the mold, and injection molding the outer layer structure 212 on the outside of the inner layer structure 211, the outer layer structure 212 wraps the inner layer structure 211, the terminal 22 and a part of the lead wire 23, and constructing a socket 203 on the outer layer structure 212 during the injection molding process, and the socket 203 is opposite to the terminal 22.

[0080] In conjunction with Figures 6 to 9, in some embodiments of the present application, a temperature-sensing component 24 is further included. The temperature-sensing component 24 is mounted on the terminal body 21 and has a temperature-sensing surface 242 exposed from the terminal body 21 for contacting the outer surface of the compressor body 10. Integrating the temperature-sensing component 24 on the terminal body 21 further improves the integration of the terminal assembly 20, simplifies the assembly process between the terminal assembly 20 and the compressor body 10, and improves the installation efficiency of the compressor 100. After the terminal body 21 is processed, the temperature-sensing component 24 can be pre-installed on the terminal body 21. When the terminal assembly 20 is connected to the compressor body 10, the temperature-sensing surface 242 of the temperature-sensing component 24 is in close contact with the compressor body 10 to achieve temperature monitoring. The temperature-sensing surface 242 of the temperature-sensing component 24 can protrude from the mating surface 201 and directly contact the outer shell of the compressor body 10.

[0081] The temperature-sensing surface 242 and the socket 203 can be located on the same side of the terminal body 21. When installing the terminal assembly 20, the terminal post 11 of the compressor body 10 can be inserted into the socket 203 and electrically connected to the terminal 22. At the same time, the temperature-sensing surface 242 contacts the outer surface of the compressor body 10. At this time, the terminal assembly 20 is fixed with a fixing member to complete the installation of the terminal 22 and the temperature-sensing component 24.

[0082] 6 and 7 , the terminal body 21 has a mounting groove 202 , the opening of the mounting groove 202 and the socket 203 are located on the same side of the terminal body 21 , and the temperature sensing component 24 is positioned in the mounting groove 202 , which can improve the installation efficiency of the temperature sensing component 24 .

[0083] Specifically, the terminal body 21 has a mating surface 201 and a mounting groove 202 provided on the mating surface 201. The mating surface 201 is opposite the shell of the compressor body 10. The temperature sensing component 24 is positioned in the mounting groove 202. A portion of the connecting wire harness 243 of the temperature sensing component 24 is located within the terminal body 21 for electrically connecting to the temperature sensing component 24, while another portion extends out of the terminal body 21. A portion of the connecting wire harness 243 is wrapped by the terminal body 21 to form a sealed structure, and the detection surface of the temperature sensing component 24 is exposed from the mating surface 201. When the terminal assembly 20 is installed on the compressor body 10, the temperature of the compressor body 10 can be detected by contacting the surface of the compressor body 10 with the detection surface.

[0084] As shown in Figure 12, to facilitate detection of the temperature-sensing component 24, the detection surface of the temperature-sensing component 24 may protrude from the mating surface 201 by a predetermined dimension a. Furthermore, in some embodiments, a waterproof gasket 25 is provided on the mating surface 201 to seal the gap between the mating surface 201 and the compressor body 10. The waterproof gasket 25 protrudes from the mating surface 201 by a predetermined dimension t, where a ≤ t. The terminal assembly 20 is configured for bolted connection to the compressor body 10. The predetermined dimensions a and t satisfy the following equation: a = 80 * t / N / Hs, where N is the tightening torque of the bolt (in N·m, a unit-less value), and Hs is the hardness of the waterproof gasket 25 (determined according to the JIS standard, a unit-less value; for example, if the hardness of the waterproof gasket 25 is JIS A30, Hs is 30). The units of a and t are millimeters. Optionally, a can be set to be no less than 0.2 mm and no greater than 0.6 mm; or t can be set to be no less than 0.5 mm and no greater than 2.0 mm. For example, a=0.4 mm, t=1.0 mm. Of course, the above parameters are only some implementation methods of the present application and are not intended to limit the scope of protection of the present application.

[0085] It will also be appreciated that the predetermined dimension a is also affected by the tightening torque N and the hardness Hs of the waterproof gasket 25. The waterproof gasket 25 undergoes elastic deformation under the pressure applied by the mating surface 201. The smaller the hardness Hs of the waterproof gasket 25, the greater the deformation that can occur. Furthermore, when tightening with bolts, the tightening torque N also affects the thickness of the waterproof gasket 25.

[0086] In some embodiments of the present application, the locking torque N is not less than 4 and not greater than 6, for example, the locking torque N can be 4, 4.3, 5, or 5.6, etc. The hardness Hs of the waterproof gasket 25 is not less than 25 and not greater than 55, for example, the hardness Hs of the waterproof gasket 25 can be 27, 29, 32, 35, 38, 39, 40, 43, 46, 50, or 51, etc. It will be appreciated that setting a range for the locking torque N and the hardness Hs is helpful in further determining the predetermined dimension a.

[0087] In combination with Figures 6 to 9, in some embodiments, the terminal assembly 20 also includes a temperature sensing terminal 241, which is arranged in the terminal body 21 and is opposite to the mounting groove 202 along the normal of the mating surface 201, and an opening corresponding to the temperature sensing terminal 241 is provided on the inner surface of the mounting groove 202, wherein the connecting harness 243 is electrically connected to the temperature sensing terminal 241, and the wiring terminal of the temperature sensing component 24 is electrically connected to the temperature sensing terminal 241.

[0088] Similar to the above, the terminal body 21 may include an inner layer structure 211 and an outer layer structure 212, and the temperature sensing terminal 241 is provided in the inner layer structure 211, and the inner layer structure 211 and the temperature sensing terminal 241 are wrapped by the outer layer structure 212. In combination with the above embodiment, the wiring terminal 22 is provided in the inner layer structure 211, the temperature sensing terminal 241 can be provided in the inner layer structure 211, and the outer layer structure 212 can be provided to wrap the inner layer structure 211, the wiring terminal 22 and the temperature sensing terminal 241. The inner layer structure 211 provided with the wiring terminal 22 and the inner layer structure 211 provided with the temperature sensing terminal 241 can be the same inner layer structure 211, or different inner layer structures 211, that is, the terminal body 21 may include one or more inner layer structures 211.

[0089] As shown in Figure 4 , the terminal assembly 20 also includes a waterproof hose 26. The waterproof hose 26 is sleeved over the outer surface of the wiring harness (including the aforementioned lead wires 23 and / or the connecting harness 243) and extends along the connecting harness 243. The waterproof hose 26 extends a predetermined length outward from the terminal body 21. A portion of the waterproof hose 26 is disposed within the terminal body 21; alternatively, the waterproof hose 26 is connected to or integrally formed with the terminal body 21.

[0090] 6 and 15 , in some embodiments of the present application, the terminal body 21 has a mating surface 201, which is used to mate with the compressor body 10. The terminal assembly 20 further includes a waterproof gasket 25, which is provided on the mating surface 201. When the terminal assembly 20 is installed on the compressor body 10, the mating surface 201 can be opposite to the compressor body 10, and the waterproof gasket 25 can be provided between the mating surface 201 and the compressor body 10. By being connected to the terminal body 21 through waterproof and dustproof means, when the terminal assembly 20 is installed on the compressor body 10, the gap between the terminal assembly 20 and the compressor body 10 can be sealed, thereby improving the waterproof and dustproof effect and stability between the terminal assembly 20 and the compressor body 10.

[0091] The waterproof gasket 25 in the present application can be installed in different ways. For example, the waterproof gasket 25 is installed on the terminal body 21, and the terminal body 21 with the waterproof gasket 25 installed is connected to the compressor body 10; or the waterproof gasket 25 is installed on the compressor body 10, and then the terminal body 21 is connected to the compressor body 10. Of course, the waterproof gasket 25 of the present application can also be installed in other ways. In some embodiments, the waterproof gasket 25 is relatively fixedly connected to the terminal body 21. When the terminal body 21 is assembled with the compressor body 10, it is no longer necessary to install the waterproof gasket 25 separately, which can further simplify the assembly efficiency of the terminal assembly 20 and the compressor 100.

[0092] The terminal body 21 and the waterproof gasket 25 in the present application can be assembled by bonding, welding, interference fit, snap connection, etc. The assembly method of the terminal body 21 and the waterproof gasket 25 in the present application includes but is not limited to the following implementation methods.

[0093] In the first embodiment, the terminal body 21 has a first positioning structure, and the waterproof gasket 25 has a second positioning structure. The second positioning structure cooperates with the first positioning structure to relatively securely connect the waterproof gasket 25 to the terminal body 21. This facilitates a stable connection between the waterproof gasket 25 and the terminal body 21, effectively improving the stability of the assembly between the waterproof gasket 25 and the terminal body 21, and enhancing the assembly and installation efficiency of the terminal assembly 20. The first and second positioning structures can cooperate to form a snap-fit ​​connection mechanism, an interference fit mechanism, an adhesive mechanism, or the like.

[0094] As an example, a first positioning structure can be set on the side of the terminal body 21 or on the surface facing away from the mating surface 201, and a second positioning structure that is compatible with the first positioning structure can be set to form a connection by snapping, bonding or welding to achieve a stable connection between the waterproof gasket 25 and the terminal body 21.

[0095] In another example, the first positioning structure can be provided on the mating surface 201, and the second positioning structure can be opposite to and assembled with the first positioning structure along the normal direction of the mating surface 201. This facilitates stable and rapid mating between the first positioning structure and the second positioning structure. When assembling the waterproof gasket 25 with the terminal body 21, it is only necessary to install the waterproof gasket 25 onto the terminal body 21 along the normal direction of the mating surface 201, thereby effectively optimizing the assembly efficiency and stability of the terminal body 21 and the waterproof gasket 25. Moreover, when the terminal body 21 is installed on the compressor body 10, the waterproof gasket 25 can be used to provide a stable and effective seal between the terminal body 21 and the compressor body 10.

[0096] It can be understood that after the second positioning structure and the first positioning structure are aligned with each other in the normal direction and assembled, the waterproof gaskets 25 are in contact with each other and are relatively fixedly connected, further improving the relative fixing effect of the waterproof gaskets 25 and the terminal body 21.

[0097] In the second embodiment, in combination with Figures 4 and 5, the first positioning structure includes a groove 204, and the second positioning structure includes a boss 251 that cooperates with the groove 204, and the boss 251 is embedded and installed in the groove 204. The boss 251 and the groove 204 can be constructed into an interference fit structure to achieve a stable fit between the boss 251 and the groove 204, which can achieve a stable installation between the waterproof gasket 25 and the terminal body 21, and the assembly efficiency between the waterproof gasket 25 and the terminal body 21 is higher. In addition, through the cooperation between the boss 251 and the groove 204, the sealing surface of the waterproof gasket 25 can be sealed, avoiding affecting the sealing effect of the waterproof gasket 25 between the terminal body 21 and the compressor body 10 during the assembly process of the waterproof gasket 25 and the terminal body 21.

[0098] It can be understood that when the boss 251 is embedded in the groove 204, the first positioning structure is assembled with the second positioning structure. At this time, the waterproof gasket 25 is in contact with the waterproof gasket 25 and is relatively fixedly connected, further improving the relative fixing effect of the waterproof gasket 25 and the terminal body 21.

[0099] Furthermore, the waterproof gasket 25 is configured as an elastic structure, which can effectively improve the sealing effect between the terminal body 21 and the compressor body 10. In addition, when the boss 251 is inserted into the groove 204, it undergoes elastic deformation, and the boss 251 and the groove 204 have an interference fit. This ensures a stable fit between the boss 251 and the groove 204, preventing the boss 251 from falling off after being connected to the groove 204, further improving the relative fixation of the waterproof gasket 25 and the terminal body 21, and effectively improving the stability of the fit between the terminal body 21 and the waterproof gasket 25.

[0100] Furthermore, the width of the boss 251 is not less than the width of the groove 204. The width of the boss 251 is the dimension along the circumference of the waterproof gasket 25, while the width of the groove 204 can be a dimension corresponding to the width of the boss 251. Since the width of the boss 251 is not less than the width of the groove 204, the boss 251 can be easily installed in the groove 204 through an interference fit, effectively improving the assembly stability between the waterproof gasket 25 and the terminal body 21.

[0101] Furthermore, referring to Figures 3 and 5 , a stress groove is provided on boss 251 to compress and deform toward the stress groove when boss 251 is inserted into groove 204. The stress groove can be located in the middle of boss 251 along the circumference of waterproof liner 25. When boss 251 is engaged with groove 204, boss 251 elastically deforms toward the stress groove, facilitating insertion of boss 251 into groove 204. Simultaneously, the stress groove disperses the excessively concentrated stress points on boss 251 after engagement with groove 204, creating new stress concentration points on boss 251. This reduces and prevents damage and deformation to boss 251 caused by the excessively concentrated stress when boss 251 engages with groove 204.

[0102] The projection of the boss 251 in the normal direction of the mating surface 201 is rectangular, trapezoidal, triangular, or semi-arc. For example, the boss 251 can be set to a rectangular shape, wherein the long side of the rectangle can be set to extend along the aforementioned radial direction, and the short side is set to be perpendicular to the radial direction; the boss 251 can also be set to a trapezoidal, triangular, or semi-arc shape, wherein the boss 251 can include a first side and a second side opposite to each other along the circumferential direction, and the first side and the second side are gradually expanded from the inside to the outside. By setting the boss 251 to a trapezoidal, triangular, or semi-arc shape, etc., a stable fit between the boss 251 and the groove 204 can be achieved, and the radial fit between the boss 251 and the groove 204 can be limited.

[0103] It can be understood that the boss 251 is configured to extend along the normal of the mating surface 201 along the projection on the mating surface 201. When the projection of the boss 251 in the normal direction of the mating surface 201 is rectangular, trapezoidal, triangular or semi-arc, since the shape of the groove 204 is adapted to the shape of the boss 251, the relative fixation of the groove 204 and the boss 251 is further achieved after the groove 204 and the boss 251 are matched.

[0104] Alternatively, the boss 251 can be configured to have a varying width in the radial direction of the waterproof gasket 25, and the shape of the groove 204 can be configured to match the shape of the boss 251, so that after the boss 251 and the groove 204 are matched, the boss 251 and the groove 204 are relatively fixedly connected. In addition, by varying the width of the boss 251 in the radial direction, the boss 251 can be displaced radially relative to the groove 204, thereby achieving radial positioning of the boss 251 and the groove 204, and improving the stable connection between the waterproof gasket 25 and the terminal body 21. The radial width of the boss 251 can be configured to gradually decrease, gradually increase, first increase and then decrease, or first decrease and then increase, etc., from the inside to the outside of the waterproof gasket 25 in the radial direction. This can achieve radial positioning of the boss 251 and the groove 204, and improve the stability of the connection between the waterproof gasket 25 and the terminal body 21.

[0105] In addition, the waterproof gasket 25 is provided with a boss 251 or a plurality of bosses 251 arranged at intervals.

[0106] In the third embodiment, the waterproof gasket 25 is bonded to the terminal body 21 by glue. It can be understood that when the glue is applied to the mating surface 201 of the terminal body 21 and the waterproof gasket 25 is relatively fixedly connected to the terminal body 21, the waterproof gasket 25 is bonded to the mating surface 201 of the terminal body 21, thereby further fixing the waterproof gasket 25 to the terminal body 21.

[0107] In combination with the above embodiments, according to some embodiments of the present application, the waterproof pad 25 is integrally formed. It can be understood that the integral formation of the waterproof pad 25 further shortens the production time of the waterproof pad 25 and improves production efficiency.

[0108] According to some embodiments of the present application, as shown in FIG4 , the terminal body 21 includes a rib 205 extending along the periphery of the mating surface 201. The waterproof gasket 25 includes a first annular portion 252 and a second annular portion 253. The first annular portion 252 and the second annular portion 253 are arranged along the normal direction of the mating surface 201. The first annular portion 252 is embedded inside the rib 205, and the second annular portion 253 is opposite to the rib 205 along the normal direction. It is understood that when the waterproof gasket 25 is connected to the terminal body 21, the first annular portion 252 is embedded inside the rib 205 to seal the mating surface 201 of the terminal body 21. In this case, the first annular portion 252 is difficult to radially displace, and the second annular portion 253 is opposite to and in contact with the rib 205 to seal the gap between the rib 205 and the compressor body 10, further improving the relative fixation effect of the waterproof gasket 25 and the terminal body 21 after connection.

[0109] In addition, the rib 205 forms a drainage groove 207 connecting the inner and outer sides of the rib 205. The terminal body 21 is provided with a mounting hole, and the drainage groove 207 corresponds to the mounting hole. The waterproof gasket 25 forms a passage connecting the drainage groove 207 and the mounting hole on the mating surface 201. The passage is separated from the socket 203 by the waterproof gasket 25. It can be understood that when liquid enters the mounting hole, it flows through the passage connecting the drainage groove 207 and the mounting hole to the drainage groove 207, and then is discharged from the mounting hole through the drainage groove 207, further achieving drainage of the mounting hole.

[0110] According to some embodiments of the present application, the waterproof gasket 25 includes at least one sealing portion, which is configured in an annular shape. A boss 251 can be connected to the sealing portion and is configured to have a shape with a varying width in the radial direction of the sealing portion. The shape of the groove 204 is adapted to the shape of the boss 251. The sealing portion is provided with multiple bosses 251, which can be arranged at intervals along the circumference of the sealing portion. One boss 251 is configured in the shape of a sector with a central angle of 40° (which can be between 25° and 90°), another boss 251 can also be configured in the shape of a sector with a central angle of 40°, and another boss 251 is configured in the shape of a rectangle.

[0111] According to some embodiments of the present application, as shown in FIG. 3 , the waterproof gasket 25 includes a connecting portion 256 and at least two sealing portions, and the at least two sealing portions are connected by the connecting portion 256 .

[0112] The mating surface 201 of the terminal body 21 may have a socket 203, and the waterproof gasket 25 may include a first sealing portion 254 arranged in an annular shape around the socket 203. It will be understood that the terminal 22 is disposed within the inner cavity 2101, and the terminal body 21 blocks the ingress of water vapor, liquid, and dust from causing harmful effects on the terminal 22, further ensuring that the terminal body 21 provides waterproof and dustproof protection for the terminal 22. When the terminal post 11 of the compressor 100 is inserted into the socket 203, it is electrically connected to the terminal 22. At this point, the terminal body 21 and the compressor 100 are mated, and the first sealing portion 254 of the waterproof gasket 25 seals the gap between the terminal body 21 and the compressor 100. During the assembly process, it is only necessary to install the terminal assembly 20 on the compressor body 10, and the terminal 11 extends into the inner cavity 2101 through the socket 203, and is electrically connected to the terminal 22 located in the inner cavity 2101. Then, the terminal assembly 20 is fixed on the compressor body 10. The terminal 22 can be quickly and stably connected to the compressor body 10, so that the electrical connection point between the terminal 22 and the terminal 11 is wrapped by the terminal body 21 to improve the stability of the electrical connection.

[0113] In other embodiments of the present application, the terminal body 21 may have a mounting groove 202, the temperature sensing component 24 is positioned in the mounting groove 202, and the waterproof gasket 25 includes a second sealing portion 255 arranged in a ring shape around the mounting groove 202; when the terminal assembly 20 is installed on the compressor 100, the temperature sensing component 24 can contact the outer surface of the compressor body 10 for temperature measurement.

[0114] In conjunction with Figures 4 and 8, in other embodiments of the present application, during the assembly process, it is only necessary to insert the temperature-sensing component 24 into the slot to electrically connect it to the temperature-sensing terminal 241. At this time, the temperature-sensing component 24 is fixed in the mounting groove 202 of the terminal body 21, and then the terminal assembly 20 is fixed to the compressor body 10. This further improves the integration of the terminal assembly 20, simplifies the assembly process between the terminal assembly 20 and the compressor body 10, and improves the installation efficiency of the compressor 100. Among them, the temperature-sensing surface 242 protrudes from the mating surface 201. After the terminal body 21 is processed, the temperature-sensing component 24 can be pre-installed on the terminal body 21. When the terminal assembly 20 is connected to the compressor body 10, the temperature-sensing surface 242 of the temperature-sensing component 24 contacts the outer surface of the compressor body 10 for temperature measurement.

[0115] In combination with the foregoing, the waterproof gasket 25 may include a first sealing portion 254 and a second sealing portion 255 , the first sealing portion 254 and the second sealing portion 255 are divided into ring shapes, and the connecting portion 256 connects the first sealing portion 254 and the second sealing portion 255 .

[0116] In some embodiments, the terminal block 22 is annular, U-shaped, or flag-shaped. When the terminal block 11 is pressed in, it can be stably electrically connected to the terminal block 22, effectively improving the stability of the electrical connection between the compressor body 10 and the terminal assembly 20.

[0117] With reference to Figures 16 to 20 , a compressor 100 according to an embodiment of the present application includes a compressor body 10 and the aforementioned terminal assembly 20 for the compressor 100 . This improves the assembly efficiency of the compressor 100 , optimizes water and electricity isolation, and enhances the operational stability of the compressor 100 . While ensuring the reliability of the compressor 100 , the integrated structure effectively reduces the labor costs of assembling the compressor 100 for air conditioner manufacturers. This solution is particularly effective for compressors 100 exported to developed countries.

[0118] In conjunction with Figures 16 and 17 , in some embodiments, a positioning post 12 is provided on the compressor body 10, and a positioning hole 206 is provided on the terminal body 21. The positioning hole 206 extends through the terminal body 21, and the positioning post 12 is inserted into the positioning hole 206. A locking member is connected to the free end of the positioning post 12. The positioning post 12 cooperates with the locking member to stably mount the terminal assembly 20 on the compressor body 10. The locking member may be a positioning pin, a positioning screw, or a positioning nut.

[0119] As shown in Figure 18, in some embodiments, the compressor body 10 is provided with an undercut structure, and the terminal body 21 is provided with a positioning portion. The terminal body 21 is pressed into place and the undercut structure and the positioning portion are engaged with each other to be positioned on the compressor body 10. Specifically, a slot can be provided on the mating surface 201 of the terminal body 21, and the undercut structure is passed through and positioned and connected to the slot to achieve a snap connection between the terminal body 21 and the compressor body 10. In addition, a slot can be provided on the side of the terminal body 21, and the undercut structure and the slot are engaged to achieve stable installation of the terminal body 21.

[0120] The HVAC equipment according to the embodiment of the present application includes the terminal assembly 20 for the compressor 100 described above; or includes the compressor 100 described above.

Through its one-piece injection-molded structure, it simplifies the installation of the air conditioning system. When assembling the terminal assembly 20 to the compressor body 10, the steps include: 1: inserting the terminal assembly 20 into the compressor body 10, inserting the positioning post 12 into the positioning hole 206, and pressing the terminal post 11 into the socket; and 2: tightening the screws. This simplifies the assembly efficiency of the terminal assembly 20 and the compressor 100, effectively reducing labor costs and achieving significant results.

[0122] This application discloses a terminal assembly 20 for a compressor 100, including a terminal block 22 for connecting to the compressor body 10 and conducting electricity. The terminal assembly 20 also includes a lead wire 23, which can be used to connect to a power source and conduct electricity.
