[0037] The embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure.

[0038] With reference to FIG. 1 to FIG. 3, with a terminal assembly 20 for a compressor 100 according to the embodiments of the present disclosure, the terminal assembly 20 may be disposed outside a compressor body 10. The compressor body 10 includes a wiring post 11 that may be used for being connected to a power source. The terminal assembly 20 may be electrically connected to the wiring post 11.

[0039] The terminal assembly 20 includes a terminal body 21 and a wiring terminal 22. The terminal body 21 has a socket 203 configured to allow a wiring post 11 of a compressor body 10 to be pressed into the socket 203. The wiring terminal 22 is disposed in the terminal body 21 and is fixed relative to the terminal body 21. When the terminal assembly 20 is connected to the compressor body 10, the wiring post 11 is pressed into the socket 203 and electrically connected to the wiring terminal 22 at an interior of the terminal body 21. During the assembly process, it is only necessary to mount the terminal assembly 20 on the compressor body 10. The wiring post 11 is inserted through the socket 203 and extends into the terminal body 21, and is electrically connected to the wiring terminal 22 located in the terminal body 21. Then, it is only necessary to fix the terminal assembly 20 on the compressor body 10. The wiring terminal 22 may be quickly and stably connected to the compressor body 10 and be disposed in the terminal body 21. In this way, an electrical connection point between the wiring terminal 22 and the wiring post 11 is wrapped by the terminal body 21, increasing stability of the electrical connection.

[0040] The terminal assembly 20 for the compressor 100 according to the embodiments of the present disclosure can improve assembly efficiency of the compressor 100, realize water-electricity isolation at the electrical connection point, and increase operational stability of the compressor 100. On the premise of ensuring reliability of the compressor 100, through the integrated structure, labor costs for an air conditioner manufacturer and other enterprises to assemble the compressor 100 can be effectively reduced. This solution has a particularly significant effect for compressors 100 exported to developed countries.

[0041] The wiring terminal 22 in the present disclosure may be used for being connected to the power source. The wiring terminal 22 may be pre-mounted in the terminal body 21, and is adapted to the terminal body 21, so that the wiring terminal 22 is fixed by the terminal body 21. When the wiring terminal 22 is used for being connected to the power source, the number of wiring posts 11 may be set to two, three, four, or other quantities according to a type of the compressor 100, and a plurality of wiring terminals 22 corresponding to the wiring posts 11 may be provided. The terminal assembly 20 may include a plurality of wiring terminals 22. Compressors 100 of different types may have two, three, four, or other numbers of wiring posts 11. The plurality of wiring terminals 22 is disposed in the terminal body 21. In order to facilitate docking between the terminal assembly 20 and the wiring posts 11, it is necessary to define relative positions of the plurality of wiring terminals 22.

[0042] As shown in FIG. 2, in some embodiments of the present disclosure, the terminal body 21 includes an inner layer structure 211 and an outer layer structure 212. The inner layer structure 211 is fixed relative to the wiring terminal 22 and serves to fix and protect the wiring terminal 22. Each of the inner layer structure 211 and the wiring terminal 22 is wrapped by the outer layer structure 212, so that the outer layer structure 212, the inner layer structure 211, and the wiring terminal 22 are fixed together relative to each other. The socket 203 is disposed at the outer layer structure 212 and opposite to the wiring terminal 22, allowing the wiring post 11 of the compressor body 10 to be inserted through the socket 203 and be electrically connected to the wiring terminal 22. Moreover, a connection position between the wiring post 11 and the wiring terminal 22 is located in the outer layer structure 212. Through the inner layer structure 211, the wiring terminal 22 may be fixed. When the inner layer structure 211 is wrapped by the outer layer structure 212, it can be ensured that the position of the wiring terminal 22 connected to the inner layer structure 211 is relatively fixed, avoiding a problem of displacement or loosening of the wiring terminal 22 during docking between the terminal assembly 20 and the compressor body 10, facilitating an increasement in structural stability of the terminal assembly 20. In addition, the inner layer structure 211 is wrapped with the outer layer structure 212, which can facilitate isolation of the inner layer structure 211 and the wiring terminal 22 relative to an external environment, and facilitate waterproof and dustproof protection of the wiring terminal 22.

[0043] In addition, in the present disclosure, the plurality of wiring terminals 22 may be positioned through the inner layer structure 211, and the inner layer structure 211 and the wiring terminals 22 may be wrapped by the outer layer structure 212. In this way, the displacement of the plurality of wiring terminals 22 can be avoided when the inner layer structure 211 is wrapped with the outer layer structure 212, and docking between the wiring post 11 of the compressor body 10 and the plurality of wiring terminals 22 can be facilitated.

[0044] With reference to FIG. 1 to FIG. 3, the inner layer structure 211 has an inner cavity 2101. The wiring terminal 22 is disposed in the inner cavity 2101. In this way, stability of the wiring terminal 22 can be further increased, preventing the displacement of the wiring terminal 22. The inner layer structure 211 may have a plurality of inner cavities 2101 that are separated from each other. The plurality of wiring terminals 22 may be respectively disposed in the plurality of inner cavities 2101, and are separated and insulated from each other by the inner layer structure 211.

[0045] With reference to FIG. 13 and FIG. 14, the inner layer structure 211 is provided with a first interface 2102 and a second interface 2103. Each of the first interface 2102 and the second interface 2103 are in communication with the inner cavity 2101. The wiring post 11 is inserted into the first interface 2102, and a wire harness is led out from the second interface 2103. The first interface 2102 may be opposite to the socket 203, and the wiring post 11 may be inserted through the socket 203, causing the first interface 2102 to be electrically connected to the wiring terminal 22. In addition, the inner layer structure 211 may have a plurality of inner cavities 2101, and each inner cavity 2101 is correspondingly provided with a first interface 2102 and a second interface 2103.

[0046] In addition, a gap may be formed between an inner surface of the inner cavity 2101 and the wiring terminal 22, and configured to provide a margin for elastic deformation of the wiring terminal 22 when the wiring post 11 is pressed into the socket 203, facilitating the insertion of the wiring post 11 and its electrical connection to the wiring terminal 22. For example, the wiring terminal 22 may have a first elastic sheet and a second elastic sheet that face towards each other. When the wiring post 11 is pressed into the socket 203, the wiring post 11 is pressed between the first elastic sheet and the second elastic sheet, causing elastic deformation of the first elastic sheet and / or the second elastic sheet. By forming a gap between the inner surface of the inner cavity 2101 and the wiring terminal 22, a margin for the deformation of the first elastic sheet and / or the second elastic sheet can be provided, facilitating a stable engagement between the wiring post 11 and the wiring terminal 22 and improving assembly efficiency between the terminal assembly 20 and the wiring post 11.

[0047] The inner layer structure 211 and the outer layer structure 212 in the present disclosure may be formed in a variety of ways. For example, the inner layer structure 211 may be formed integrally or separately. The inner layer structure 211 includes, but is not limited to the following implementation.

[0048] In a first implementation, as shown in FIG. 10 and FIG. 11, the inner layer structure 211 is divided into a first part 2111 and a second part 2112 that are fitted together. After the first part 2111 and the second part 2112 are fitted together, an inner cavity 2101 is formed between the first part 2111 and the second part 2112, and configured to receive the wiring terminal 22. Since the first part 2111 and the second part 2112 are in a fitting form, the wiring terminal 22 may 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, facilitating mounting and positioning of the wiring terminal 22.

[0049] The first part 2111 and the second part 2112 may be fixedly connected by a fastener (such as a bolt, a pin, and a rivet). Alternatively, the first part 2111 and the second part 2112 may also be fixedly connected by welding, bonding, or other manners. Alternatively, after the first part 2111 and the second part 2112 are fitted together, the first part 2111 and the second part 2112 are fixedly connected together using the outer layer structure 212. In other embodiments of the present disclosure, the above descriptions are merely some implementations of the present disclosure and are not intended to limit the protection scope of the present disclosure.

[0050] In a second implementation, the inner layer structure 211 is integrally formed. The inner layer structure 211 may have an inner cavity 2101, and the wiring terminal 22 is mounted in the inner cavity 2101. Through the integral forming, a structural strength of the inner layer structure 211 can be improved, a service life of the terminal assembly 20 can be improved, and processing efficiency of the inner layer structure 211 can be improved.

[0051] In a third implementation, the inner layer structure 211 may be formed by injection molding. In some examples, the inner layer structure 211 may be separately formed. For example, the inner layer structure 211 includes the first part 2111 and the second part 2112. The first part 2111 and the second part 2112 are respectively formed by injection molding and then assembled together. In other examples, the inner layer structure 211 may also be integrally formed by injection molding.

[0052] The forming manners of the inner layer structure 211 and the outer layer structure 212 in the present disclosure include, but are not limited to the following implementations.

[0053] In a first implementation, the inner layer structure 211 and the outer layer structure 212 may be formed separately, and then assembled after being formed respectively.

[0054] In a second implementation, after the inner layer structure 211 is formed by injection molding, the outer layer structure 212 may be formed by secondary injection molding together with the inner layer structure 211. In this way, the position of the wiring terminal 22 can be maintained through the inner layer structure 211, avoiding the displacement of the wiring terminal 22 during the secondary injection molding, and facilitating the provision of a deformation margin for the wiring terminal 22 to facilitate the docking between the wiring post 11 and the wiring terminal 22. Through the secondary injection molding of the outer layer structure 212, waterproof and dustproof protection of the inner layer structure 211 and the wiring terminal 22 are ensured, increasing the stability of the terminal assembly 20.

[0055] In other embodiments of the present disclosure, each of the inner layer structure 211 and the outer layer structure 212 may also be formed separately in other manners.

[0056] In the present disclosure, the inner layer structure 211 may be a block made of PBT (i.e., polybutylene terephthalate) material mixed with a flame retardant. Alternatively, the outer layer structure 212 may be a block made of PBT material mixed with a flame retardant. In this way, flame-retardant performance of the terminal body 21 can be ensured, and the stability and safety of the terminal assembly 20 can be increased. In addition, the inner layer structure 211 may also be configured as a block made of PVC (i.e., polyvinyl chloride) material, or nylon material. The outer layer structure 212 may also be configured as a block made of PVC material, or nylon material.

[0057] In addition, in some embodiments of the present disclosure, the terminal body 21 may also be integrally formed by injection molding, which can simplify manufacturing process of the terminal body 21. Moreover, the wiring terminal 22 may be disposed in the terminal body 21 during the integral forming process of the terminal body 21. In this way, a waterproof and dustproof effect of the terminal assembly 20 can be ensured, and forming efficiency and stability of the terminal assembly 20 can be improved.

[0058] In addition, as shown in FIG. 4 and FIG. 5, in some embodiments of the present disclosure, the terminal assembly 20 further includes a lead wire 23. One end of the lead wire 23 is connected to the wiring terminal 22, and another end of the lead wire 23 extends out of the terminal body 21 for connection to an external device. For example, the lead wire 23 may be used to connect to a power source, a controller, or the like. The present disclosure mainly takes the use of the lead wire 23 to connect to the power source for supplying power to the compressor 100 as an example for description. A sealing structure may be formed between the lead wire 23 and the outer layer structure 212 to improve the waterproof and dustproof effect of the wiring terminal 22. For example, the outer layer structure 212 may be formed by injection molding, and the lead wire 23 is wrapped and fixed in the outer layer structure 212 during the formation of the outer layer structure 212 by injection molding, which can improve sealing performance between the lead wire 23 and the terminal body 21. Specification of the lead wire 23 may be selected according to a current magnitude, and a conductor cross-section of the lead wire 23 may be set to be greater than or equal to 4 square millimeters.

[0059] In combination with the above, a manufacturing method for the terminal assembly 20 of the present disclosure may include: connecting the wiring terminal 22 to the lead wire 23; manufacturing the inner layer structure 211 with the inner cavity 2101, mounting the wiring terminal 22 in the inner cavity 2101, and extending the lead wire 23 out of the inner cavity 2101; and positioning the inner layer structure 211 with the wiring terminal 22 mounted therein in a mold, and forming the outer layer structure 212 at an outer side of the inner layer structure 211 by injection molding. The inner layer structure 211, the wiring terminal 22, and a part of the lead wire 23 are wrapped by the outer layer structure 212. During the injection molding process, the socket 203 is formed at the outer layer structure 212 and opposite to the wiring terminal 22.

[0060] With reference to FIG. 6 to FIG. 9, in some embodiments of the present disclosure, the terminal assembly 20 further includes a temperature-sensing component 24 mounted at the terminal body 21. The temperature-sensing component 24 has a temperature-sensing surface 242 exposed from the terminal body 21 and configured to contact an outer surface of the compressor body 10. By integrating the temperature-sensing component 24 into the terminal body 21, an integration degree of the terminal assembly 20 is further improved, an assembly process between the terminal assembly 20 and the compressor body 10 is simplified, and mounting efficiency of the compressor 100 is improved. After processing of the terminal body 21 is completed, the temperature-sensing component 24 may be pre-mounted 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 closely attached to the compressor body 10 to realize temperature monitoring. The temperature-sensing surface 242 of the temperature-sensing component 24 may protrude from the mating surface 201 and be in direct contact with a housing of the compressor body 10.

[0061] The temperature-sensing surface 242 and the socket 203 may be formed at one side of the terminal body 21. When the terminal assembly 20 is mounted, the wiring post 11 of the compressor body 10 may be inserted through the socket 203 and be electrically connected to the wiring terminal 22. Meanwhile, the temperature-sensing surface 242 is in contact with the outer surface of the compressor body 10. At this time, the terminal assembly 20 is fixed by a fastener, which can complete mounting of the wiring terminal 22 and the temperature-sensing component 24.

[0062] In another exemplary embodiment of the present disclosure, as shown in FIG. 6 and FIG. 7, the terminal body 21 has a mounting groove 202. An opening of the mounting groove 202 and the socket 203 are located at one side of the terminal body 21, and the temperature-sensing component 24 is positioned in the mounting groove 202. In this way, mounting efficiency of the temperature-sensing component 24 can be improved.

[0063] In an exemplary embodiment of the present disclosure, the terminal body 21 has a mating surface 201, and the mounting groove 202 is formed on the mating surface 201. The mating surface 201 is opposite to the housing of the compressor body 10. The temperature-sensing component 24 is positioned in the mounting groove 202. A part of a connection wire harness 243 of the temperature-sensing component 24 located in the terminal body 21 is configured to electrically connect to the temperature-sensing component 24, and another part of the connection wire harness 243 extends out of the terminal body 21. A part of the connection wire harness 243 is wrapped by the terminal body 21 to form a sealing structure, and a detection surface of the temperature-sensing component 24 is exposed from the mating surface 201. When the terminal assembly 20 is mounted on the compressor body 10, temperature detection of the compressor body 10 may be realized through contact of the detection surface with the surface of the compressor body 10.

[0064] As shown in FIG. 12, in order to facilitate the 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. In addition, in some embodiments, a waterproof gasket 25 is provided at the mating surface 201 and configured to seal a 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 to be connected to the compressor body 10 by a bolt locking in a locked manner. The predetermined dimension a and the predetermined dimension t satisfy: a = 80*t / N / Hs, where N is a locking torque of the bolt (unit: N·m; and N represents a numerical value excluding the unit), Hs is a hardness of the waterproof gasket 25 (that is determined in accordance with JIS standards; Hs represents a numerical value excluding the unit; and for example, when the hardness of the waterproof gasket 25 is JIS A30, Hs is 30), and the units of a and t are millimeters. In another exemplary embodiment of the present disclosure, a may be set to be greater than or equal to 0.2 mm and smaller than or equal to 0.6 mm. Alternatively, t may be set to be greater than or equal to 0.5 mm and smaller than or equal to 2.0 mm. For example, a is equal to 0.4 mm, and t is equal to 1.0 mm. In other embodiments of the present disclosure, the above parameters are merely some implementations of the present disclosure and are not intended to limit the protection scope of the present disclosure.

[0065] It can also be understood that the predetermined dimension a is also affected by the locking torque N and the hardness Hs of the waterproof gasket 25. The waterproof gasket 25 may undergo elastic deformation when subjected to pressure applied by the mating surface 201. The smaller the hardness Hs of the waterproof gasket 25, the greater the deformability of the waterproof gasket 25. Meanwhile, when bolt locking is used, the locking torque N also affects a thickness of the waterproof gasket 25.

[0066] In some embodiments of the present disclosure, the locking torque N is greater than or equal to 4 and smaller than or equal to 6. For example, the locking torque N may be 4, 4.3, 5, 5.6, or the like. The hardness Hs of the waterproof gasket 25 is greater than or equal to 25 and smaller than or equal to 55. For example, the hardness Hs of the waterproof gasket 25 may be 27, 29, 32, 35, 38, 39, 40, 43, 46, 50, 51, or the like. It can be understood that the range settings of the locking torque N and the hardness Hs are beneficial to further determination of the predetermined dimension a.

[0067] With reference to FIG. 6 to FIG. 9, in some embodiments, the terminal assembly 20 further includes a temperature-sensing terminal 241 disposed in the terminal body 21 and opposite to the mounting groove 202 in a normal direction of the mating surface 201. Moreover, the mounting groove 202 has an opening formed at an inner surface of the mounting groove 202. The opening corresponds to the temperature-sensing terminal 241. The connection wire harness 243 is electrically connected to the temperature-sensing terminal 241, and a terminal of the temperature-sensing component 24 is electrically connected to the temperature-sensing terminal 241.

[0068] Similar to the foregoing, the terminal body 21 may include the inner layer structure 211 and the outer layer structure 212; the temperature-sensing terminal 241 may be disposed in the inner layer structure 211, and the inner layer structure 211 and the temperature-sensing terminal 241 may be wrapped by using the outer layer structure 212. In combination with the foregoing embodiments, the wiring terminal 22 is disposed in the inner layer structure 211, the temperature-sensing terminal 241 may be disposed in the inner layer structure 211, and the inner layer structure 211, the wiring terminal 22, and the temperature-sensing terminal 241 may be set to be wrapped by the outer layer structure 212. The inner layer structure 211 provided with the wiring terminal 22 and the inner layer structure 211 provided with the temperature-sensing terminal 241 may be one inner layer structure 211 or different inner layer structures 211, i.e., the terminal body 21 may include one or more inner layer structures 211.

[0069] As shown in FIG. 4, the terminal assembly 20 further includes a waterproof hose 26 sleeved on an outer surface of the wire harness (including the above lead wire 23 and / or connection wire harness 243) and extending along the connection wire harness 243. The waterproof hose 26 extends out of the terminal body 21 by a predetermined length. A part of the waterproof hose 26 is located in the terminal body 21. Alternatively, the waterproof hose 26 is connected to or integrally formed with the terminal body 21.

[0070] With reference to FIG. 6 and FIG. 15, in some embodiments of the present disclosure, the mating surface 201 formed on the terminal body 21 is configured to mate with the compressor body 10. The terminal assembly 20 further includes the waterproof gasket 25 disposed at the mating surface 201. When the terminal assembly 20 is mounted on the compressor body 10, the mating surface 201 may face towards the compressor body 10, and the waterproof gasket 25 may be disposed between the mating surface 201 and the compressor body 10. By connecting a waterproof and dustproof component (i.e., the waterproof gasket 25) to the terminal body 21, when the terminal assembly 20 is mounted on the compressor body 10, a gap between the terminal assembly 20 and the compressor body 10 can be sealed, improving a waterproof and dustproof effect and stability between the terminal assembly 20 and the compressor body 10.

[0071] The waterproof gasket 25 in the present disclosure may be mounted in different ways. For example, the waterproof gasket 25 is mounted on the terminal body 21, and then the terminal body 21 with the waterproof gasket 25 mounted thereon is connected to the compressor body 10. Alternatively, the waterproof gasket 25 is mounted on the compressor body 10, and then the terminal body 21 is connected to the compressor body 10. In other embodiments of the present disclosure, the waterproof gasket 25 in the present disclosure may also be mounted in other ways. In some embodiments, the waterproof gasket 25 and the terminal body 21 are fixedly connected relative to each other. When the terminal body 21 is assembled with the compressor body 10, there is no need to mount the waterproof gasket 25 separately, which can further simplify the assembly efficiency of the terminal assembly 20 and the compressor 100.

[0072] The terminal body 21 and the waterproof gasket 25 in the present disclosure may be assembled by bonding, welding, interference fit, snap-fit connection, or the like. The assembly manners of the terminal body 21 and the waterproof gasket 25 in the present disclosure include, but are not limited to the following implementations.

[0073] In a first implementation, the terminal body 21 has a first positioning structure, and the waterproof gasket 25 has a second positioning structure. The second positioning structure is engaged with the first positioning structure to allow the waterproof gasket 25 and the terminal body 21 to be fixedly connected relative to each other. In this way, a stable connection between the waterproof gasket 25 and the terminal body 21 can be facilitated, assembly stability between the waterproof gasket 25 and the terminal body 21 can be effectively increased, and assembly and mounting efficiency of the terminal assembly 20 can be improved. The first positioning structure and the second positioning structure may be engaged with each other to form a snap-fit connection mechanism, an interference fit mechanism, an adhesive mechanism, or the like.

[0074] In an example, the first positioning structure may be provided at a side surface of the terminal body 21 or a surface at a side of the terminal body 21 facing away from the mating surface 201, and the second positioning structure adapted to the first positioning structure is provided for engagement with the first positioning structure. Connections such as snap, bonding, or welding are formed to realize the stable connection between the waterproof gasket 25 and the terminal body 21.

[0075] In another example, the first positioning structure may also be disposed at the mating surface 201, and the second positioning structure is opposite to and assembled with the first positioning structure in a normal direction of the mating surface 201. In this way, a stable and rapid engagement between the first positioning structure and the second positioning structure can be facilitated. When the waterproof gasket 25 is assembled with the terminal body 21, it is only necessary to mount the waterproof gasket 25 on the terminal body 21 in the normal direction of the mating surface 201, effectively increasing assembly efficiency and stability of the terminal body 21 and the waterproof gasket 25. Moreover, when the terminal body 21 is mounted on the compressor body 10, the waterproof gasket 25 may be used to provide stable and effective sealing between the terminal body 21 and the compressor body 10.

[0076] It can be understood that after the second positioning structure is opposite to and assembled with the first positioning structure in the normal direction, the waterproof gasket 25 is in contact with the terminal body 21 and connected fixedly relative to the terminal body 21, which further improves an effect of fixation of the waterproof gasket 25 relative to the terminal body 21.

[0077] In a second implementation, with reference to FIG. 4 and FIG. 5, the first positioning structure includes a groove 204, and the second positioning structure includes a boss 251 engaged with the groove 204. The boss 251 is embedded and mounted in the groove 204. An interference fit structure may be formed between the boss 251 and the groove 204 to realize a stable engagement between the boss 251 and the groove 204. In this way, stable mounting between the waterproof gasket 25 and the terminal body 21 can be realized, and assembly efficiency between the waterproof gasket 25 and the terminal body 21 can be higher. In addition, through the engagement between the boss 251 and the groove 204, a sealing surface that affects the waterproof gasket 25 can be sealed, avoiding the impact on a 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.

[0078] It can be understood that when the boss 251 is embedded in the groove 204, the first positioning structure and the second positioning structure are assembled. At this time, the waterproof gasket 25 is in contact with the terminal body 21 and connected fixedly relative to the terminal body 21, which further improves the effect of the fixation of the waterproof gasket 25 relative to the terminal body 21.

[0079] Further, the waterproof gasket 25 is configured as an elastic structure, which can effectively improve a sealing effect between the terminal body 21 and the compressor body 10. In addition, the boss 251 undergoes elastic deformation when embedded in the groove 204, forming an interference fit between the boss 251 and the groove 204. In this way, the stable engagement between the boss 251 and the groove 204 is realized, and the boss 251 is prevented from being disengaged from the groove 204 after being connected to the groove 204, which further improves the effect of the fixation of the waterproof gasket 25 relative to the terminal body 21, and effectively increases the engagement stability between the terminal body 21 and the waterproof gasket 25.

[0080] Further, a width dimension of the boss 251 is greater than or equal to a width dimension of the groove 204. The width dimension of the boss 251 refers to a dimension in a circumferential direction of the waterproof gasket 25, and a width of the groove 204 may be a dimension corresponding to a width of the boss 251. Since the width dimension of the boss 251 is greater than or equal to the width dimension of the groove 204, it can be facilitated that the boss 251 is mounted in the groove 204 in an interference fit manner, which effectively increases the assembly stability between the waterproof gasket 25 and the terminal body 21.

[0081] Further, with reference to FIG. 3 and FIG. 5, the boss 251 has a stress groove formed thereon. The boss 251 is squeezed and deformed towards the stress groove when embedded in the groove 204. The stress groove may be formed at a middle part of the boss 251 in the circumferential direction of the waterproof gasket 25. When the boss 251 is engaged with the groove 204, the boss 251 undergoes elastic deformation towards the stress groove, which facilitates embedding the boss 251 into the groove 204. Meanwhile, the stress groove disperses overly concentrated stress points after the boss 251 is engaged with the groove 204, forming new stress concentration points on the boss 251, reducing and avoiding damage and deformation of the boss 251 caused by overly concentrated stress during the engagement between the boss 251 and the groove 204.

[0082] A projection of the boss 251 in the normal direction of the mating surface 201 is of a rectangular, trapezoidal, triangular, or semi-arc shape. For example, the boss 251 may be constructed to have a rectangular shape, in which a long side of the rectangle may be set to extend in the above radial direction, and a short side of the rectangle may be set to extend in a direction perpendicular to the radial direction. The boss 251 may also be constructed to have a trapezoidal, triangular, or semi-arc shape. The boss 251 may include a first side and a second side opposite to each other in a circumferential direction of the boss 251. The first side and the second side may be configured to expand outwards gradually from the inside to the outside. By constructing the boss 251 as a trapezoidal, triangular, or semi-arc shape, the stable engagement between the boss 251 and the groove 204 can be achieved, and engagement and limiting between the boss 251 and the groove 204 in the radial direction can be realized.

[0083] It can be understood that the boss 251 is configured to extend in the normal direction of the mating surface 201 according to its projection on the mating surface 201. When the projection of the boss 251 in the normal direction of the mating surface 201 is of a rectangular, trapezoidal, triangular, or semi-arc shape, since a shape of the groove 204 is adapted to a shape of the boss 251, after the groove 204 is engaged with the boss 251, fixation of the groove 204 relative to the boss 251 is further achieved.

[0084] In another exemplary embodiment of the present disclosure, the boss 251 may be constructed to have a shape with a variable width dimension in a radial direction of the waterproof gasket 25. After the shape of the groove 204 is set to match the shape of the boss 251 to realize the engagement between the boss 251 and the groove 204, the boss 251 and the groove 204 are connected fixedly relative to each other. In addition, through the width variation of the boss 251 in the radial direction, displacement of the boss 251 relative to the groove 204 in the radial direction can be realized, radial positioning of the boss 251 and the groove 204 can be realized, and the stable connection between the waterproof gasket 25 and the terminal body 21 can be improved. The width dimension of the boss 251 in the radial direction may be set such that, in the radial direction of the waterproof gasket 25 from the inside to the outside, the width dimension decreases gradually, increases gradually, first increases then decreases, or first decreases then increases, etc. In this way, the positioning of the boss 251 and the groove 204 in the radial direction can be realized, and the connection stability between the waterproof gasket 25 and the terminal body 21 can be increased.

[0085] In addition, the waterproof gasket 25 is provided with one boss 251 or a plurality of bosses 251 arranged at intervals.

[0086] In a third implementation, the waterproof gasket 25 is adhered to the terminal body 21 by glue. It can be understood that the glue is coated to the mating surface 201 of the terminal body 21. When the waterproof gasket 25 and the terminal body 21 are fixedly connected relative to each other, the waterproof gasket 25 is adhered to the mating surface 201 of the terminal body 21, which further realizes the fixation of the waterproof gasket 25 and the terminal body 21.

[0087] In combination with the foregoing embodiments, according to some embodiments of the present disclosure, the waterproof gasket 25 is integrally formed. It can be understood that the integral forming of the waterproof gasket 25 further shortens a manufacturing time of the waterproof gasket 25 and improves production efficiency.

[0088] According to some embodiments of the present disclosure, as shown in FIG. 4, the terminal body 21 includes a protruding rib 205 extending along a periphery of the mating surface 201. The waterproof gasket 25 includes a first annular portion 252 and a second annular portion 253 that are arranged in a normal direction of the mating surface 201. The first annular portion 252 is embedded inside the protruding rib 205, and the second annular portion 253 is opposite to the protruding rib 205 in the normal direction. It can be understood that when the waterproof gasket 25 is connected to the terminal body 21, the first annular portion 252 is embedded inside the protruding rib 205 to seal the mating surface 201 of the terminal body 21. At this time, radial displacement of the first annular portion 252 is difficult to occur. The second annular portion 253 is opposite to and in contact with the protruding rib 205 to seal a gap between the protruding rib 205 and the compressor body 10, further improving the effect of fixation of the waterproof gasket 25 relative to the terminal body 21 after the waterproof gasket 25 is connected to the terminal body 21.

[0089] In addition, the protruding rib 205 is constructed to have a drainage groove 207. An inner side of the protruding rib 205 is in communication with an outer side of the protruding rib 205 through the drainage groove 207. The terminal body 21 has a mounting hole corresponding to the drainage groove 207. The waterproof gasket 25 is constructed to have a channel defined at the mating surface 201. The drainage groove 207 is in communication with the mounting hole through the channel, and the channel is separated from the socket 203 by the waterproof gasket 25. It can be understood that when liquid enters through the mounting hole, the liquid reaches the drainage groove 207 through the channel connecting the drainage groove 207 and the mounting hole, and then is discharged out of the mounting hole through the drainage groove 207, further realizing the drainage of the mounting hole.

[0090] According to some embodiments of the present disclosure, the waterproof gasket 25 includes at least one sealing portion constructed to have an annular shape. The boss 251 may be connected to the sealing portion and constructed to have a shape with a variable width dimension in a radial direction of the sealing portion, and the shape of the groove 204 is adapted to the shape of the boss 251. The sealing portion is provided with a plurality of bosses 251. The plurality of bosses 251 may be arranged at intervals in a circumferential direction of the sealing portion. For example, one of the bosses 251 may be constructed to have a fan shape with a central angle of 40° (that may range from 25° to 90°), another boss 251 may also be constructed to have a fan shape with a central angle of 40°, and yet another boss 251 may be constructed to have a rectangular shape.

[0091] According to some embodiments of the present disclosure, as shown in FIG. 3, the waterproof gasket 25 includes a connection portion 256 and at least two sealing portions. The at least two sealing portions are connected by the connection portion 256.

[0092] 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 annularly surrounding the socket 203. It can be understood that the wiring terminal 22 is disposed in the inner cavity 2101, and the terminal body 21 blocks water vapor, liquid, and dust from entering and causing a harmful effect on the wiring terminal 22, which further realizes the waterproof and dustproof protection of the wiring terminal 22 by the terminal body 21. When the wiring post 11 of the compressor 100 is inserted into the socket 203, the wiring post 11 is electrically connected to the wiring terminal 22. At this time, the terminal body 21 is engaged with the compressor 100, and the first sealing portion 254 of the waterproof gasket 25 seals a gap between the terminal body 21 and the compressor 100. During the assembly process, it is only necessary to mount the terminal assembly 20 on the compressor body 10. The wiring post 11 is inserted through the socket 203 and extends into the inner cavity 2101, and is electrically connected to the wiring terminal 22 located in the inner cavity 2101. Then, it is only necessary to fix the terminal assembly 20 on the compressor body 10. The wiring terminal 22 may be quickly and stably connected to the compressor body 10. In this way, the electrical connection point between the wiring terminal 22 and the wiring post 11 is wrapped by the terminal body 21, increasing the stability of the electrical connection.

[0093] In other embodiments of the present disclosure, the terminal body 21 may have a mounting groove 202, and the temperature-sensing component 24 is positioned in the mounting groove 202. The waterproof gasket 25 includes a second sealing portion 255 annularly surrounding the mounting groove 202. When the terminal assembly 20 is mounted on the compressor 100, the temperature-sensing component 24 may be in contact with the outer surface of the compressor body 10 for temperature measurement.

[0094] With reference to FIG. 4 and FIG. 8, in other embodiments of the present disclosure, during the assembly process, it is only necessary to insert the temperature-sensing component 24 into a slot to achieve an electrical connection with 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 on the compressor body 10. In this way, the integration degree of the terminal assembly 20 is further improved, the assembly process between the terminal assembly 20 and the compressor body 10 is simplified, and the mounting efficiency of the compressor 100 is improved. The temperature-sensing surface 242 protrudes from the mating surface 201. After the processing of the terminal body 21 is completed, the temperature-sensing component 24 may be pre-mounted 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 contact with the outer surface of the compressor body 10 for temperature measurement.

[0095] 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 respectively annular, and the first sealing portion 254 and the second sealing portion 255 are connected by the connection portion 256.

[0096] In some embodiments, the wiring terminal 22 is of annular, U-shaped, or flag-shaped, allowing for a stable electrical connection of the wiring post 11 with the wiring terminal 22 when the wiring post 11 is pressed into the socket 203, effectively increasing the stability of the electrical connection between the compressor body 10 and the terminal assembly 20.

[0097] With reference to FIG. 16 to FIG. 20, the compressor 100 according to the embodiments of the present disclosure includes the above terminal assembly 20 for the compressor 100 and the compressor body 10. In this way, the assembly efficiency of the compressor 100 can be improved, a water-electricity isolation effect can be enhanced, and the operational stability of the compressor 100 can be increased. On the premise of ensuring the reliability of the compressor 100, through the integrated structure, labor costs for an air conditioner manufacturer and other enterprises to assemble the compressor 100 can be effectively reduced. This solution has a particularly significant effect for compressors 100 exported to developed countries.

[0098] With reference to FIG. 16 to FIG. 17, in some embodiments, the compressor body 10 is provided with a positioning post 12, and a terminal body 21 has a positioning hole 206. The positioning hole 206 penetrates the terminal body 21. The positioning post 12 is inserted into the positioning hole 206, and a free end of the positioning post 12 is connected to a locking member. Through an engagement between the positioning post 12 and the locking member, the terminal assembly 20 can be stably mounted on the compressor body 10. The locking member may be a positioning pin, a positioning screw, a positioning nut, or the like.

[0099] As shown in FIG. 18, in some embodiments, the compressor body 10 has an undercut structure, and the terminal body 21 is provided with a positioning portion. The terminal body 21 is pressed in place and the undercut structure is snap-fitted with the positioning portion, to position the terminal body 21 at the compressor body 10. In an exemplary embodiment of the present disclosure, a clamping groove may be formed at the mating surface 201 of the terminal body 21, and the undercut structure is inserted into and positioned in the clamping groove to realize a snap-fit connection between the terminal body 21 and the compressor body 10. In addition, the clamping groove may also be formed at the side surface of the terminal body 21. The undercut structure is engaged with the clamping groove to realize the stable mounting of the terminal body 21.

[0100] A heating and ventilation device according to the embodiments of the present disclosure includes the above terminal assembly 20 for the compressor 100 or the above compressor 100.

[0101] With the terminal assembly 20 for the compressor 100, the compressor 100, and the heating and ventilation device according to the embodiments of the present disclosure, the terminal assembly 20 is integrated with components such as the wiring terminal 22, the lead wire 23, the temperature-sensing component 24, and the waterproof gasket 25. Through an integral injection-molded structure, the function of simplifying the mounting of the air conditioning system is realized. When the terminal assembly 20 is assembled onto the compressor body 10, the method includes: step 1 of mounting the terminal assembly 20 onto the compressor body 10 through insertion, and inserting the positioning post 12 into the positioning hole 206 and pressing the wiring post 11 into an insertion hole; step 2 of tightening screws. In this way, the assembly efficiency of the terminal assembly 20 and the compressor 100 is simplified, labor costs are effectively reduced, and a significant effect is achieved.

[0102] The present disclosure discloses a terminal assembly 20 for a compressor 100, which includes a wiring terminal 22 for connecting to the compressor body 10 and conducting electricity. The terminal assembly 20 further includes the lead wire 23, which can be used for being connected to a power source and conducting electricity. In addition, the terminal assembly 20 may further integrate the temperature-sensing component 24 for monitoring a temperature of the compressor 100. The terminal body 21 may be formed by injection molding (e.g., integrally formed by injection molding). The terminal assembly 20 further includes the waterproof gasket 25 engaged with the terminal body 21 to achieve self-fixation and realize dustproof and waterproof protection.
