Detailed Description of the Embodiment

[0049] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] Combined with Figures 1 to 3 , for the compressor 10 with the integrated terminal 20 according to the embodiment of the present invention, the integrated terminal 20 is provided outside the compressor 10. The compressor 10 includes a terminal post 11, and the terminal post 11 can be used to connect to a power source. The integrated terminal 20 can be electrically connected to the terminal post 11.

[0051] The integrated terminal 20 includes a terminal body 21 and a wiring terminal 22. The terminal body 21 has a socket 2103 for pressing into the terminal post 11. The wiring terminal 22 is wrapped inside the terminal body 21 and is relatively fixed to the terminal body 21. When connecting the compressor 10, the terminal post 11 of the compressor 10 is pressed into the socket 2103, and the terminal post 11 is electrically connected to the wiring terminal 22 inside the terminal body 21. During the assembly process, only the integrated terminal 20 needs to be installed on the compressor 10. The terminal post 11 passes through the socket 2103 and extends into the terminal body 21, and is electrically connected to the wiring terminal 22 located inside the terminal body 21. Then, the integrated terminal 20 is fixed on the compressor 10. The wiring terminal 22 can quickly and stably connect the compressor 10 and is wrapped inside the terminal body 21 to wrap the electrical connection point of the wiring terminal 22 and the terminal post 11 through the terminal body 21, improving the stability of the electrical connection.

[0052] The integrated terminal 20 for the compressor 10 according to the embodiment of the present invention can improve the assembly efficiency of the compressor 10, achieve the water and electricity isolation at the electrical connection point, and improve the operation stability of the compressor 10. On the premise of ensuring the reliability of the compressor 10, the labor cost of assembling the compressor 10 by air conditioner manufacturers and the like can be effectively reduced through the integrated structure. Especially for the compressor 10 exported to developed countries, this solution has obvious effects.

[0053] Combined with the foregoing, the wiring terminal 22 in the present invention can be used to connect the power supply. A plurality of wiring terminals 22 can be pre-installed inside the terminal body 21. The wiring terminals 22 are adapted to the terminal body 21, and the wiring terminals 22 are fixed by the terminal body 21. Among them, when the wiring terminal 22 is used to connect the power supply, two, three, four or other numbers of terminal posts can be set according to the type of the compressor, and the wiring terminals 22 can be set to be multiple corresponding to the terminal posts.

[0054] Such as Figure 2, in some embodiments of the present invention, the terminal body 21 includes an inner layer structure 211 and an outer layer structure 212. The inner layer structure 211 is fixedly connected to the wiring terminal 22 relatively, playing a role of fixing and protecting the wiring terminal 22. The outer layer structure 212 wraps the inner layer structure 211 and the wiring terminal 22 to connect the outer layer structure 212, the inner layer structure 211 and the wiring terminal 22 relatively fixedly together. The socket 2103 is arranged on the outer layer structure 212, and the socket 2103 faces the wiring terminal 22, for the terminal post 11 of the compressor 10 to pass through the socket 2103 and be electrically connected to the wiring terminal 22, and the connection position between the terminal post 11 and the wiring terminal 22 is located inside the outer layer structure 212. Through the inner layer structure 211, the wiring terminal 22 can be fixed. When the outer layer structure 212 wraps the inner layer structure 211, it can ensure that the position of the wiring terminal 22 connected to the inner layer structure 211 is relatively fixed, avoiding the problems of displacement or loosening of the wiring terminal 22 during the docking process of the integrated terminal 20 and the compressor 10, thereby facilitating the improvement of the structural stability of the integrated terminal 20. In addition, by using the outer layer structure 212 to wrap the inner layer structure 211, it can facilitate the relative isolation of the inner layer structure 211 and the wiring terminal 22 from the external environment, and is convenient for waterproofing and dustproofing of the wiring terminal 22.

[0055] In addition, in combination with Figures 4 to 18 , in the present invention, the integrated terminal 20 may include a plurality of wiring terminals 22. For different types of compressors 10, there may be two, three, four or other numbers of terminal posts 11. The plurality of wiring terminals 22 are wrapped inside the terminal body 21. In order to facilitate the docking of the integrated terminal 20 and the terminal post, it is necessary to define the relative positions of the plurality of wiring terminals 22. Among them, the plurality of wiring terminals 22 can be positioned by the inner layer structure 211, and the inner layer structure 211 and the wiring terminals 22 are wrapped by the outer layer structure 212. It can avoid the displacement of the plurality of wiring terminals 22 when the outer layer structure 212 wraps the inner layer structure 211, and is convenient for the docking of the terminal post 11 of the compressor 10 and the plurality of wiring terminals 22.

[0056] Referring to Figures 1 to 3 , and in combination with Figure 12 and Figure 13 , the inner layer structure 211 has an inner cavity 2101, and the wiring terminal 22 is arranged in the inner cavity 2101. Thereby, the stability of the wiring terminal 22 can be further improved, and the displacement of the wiring terminal 22 can be avoided. Among them, the inner layer structure 211 may have a plurality of inner cavities 2101, and the plurality of inner cavities 2101 are separated from each other. The plurality of wiring terminals 22 can be respectively arranged in the plurality of inner cavities 2101, and the plurality of wiring terminals 22 are separated and insulated from each other by the inner layer structure 211.

[0057] Among them, referring to Figure 11 and Figure 12, the inner layer structure 211 is provided with a first interface and a second interface. Among them, the first interface and the second interface are communicated with the inner cavity 2101. The first interface is for the terminal 11 to be inserted, and the second interface is for the wire harness to be led out. The first interface can be opposite to the socket 2103, and the terminal 11 can pass through the socket 2103 and the first interface to be electrically connected to the terminal 22. In addition, the inner layer structure 211 can have a plurality of inner cavities 2101, and each inner cavity 2101 is correspondingly provided with a first interface and a second interface.

[0058] 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 a margin for elastic deformation of the terminal 22 when the terminal 11 is pressed in, so as to facilitate the insertion and electrical connection of the terminal 11 to the terminal 22. For example, the terminal 22 can have a first elastic piece and a second elastic piece, and the first elastic piece and the second elastic piece are arranged oppositely. When the terminal 11 is pressed in, the terminal 11 is pressed between the first elastic piece and the second elastic piece, and the first elastic piece and / or the second elastic piece 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 elastic piece and / or the second elastic piece, so as to facilitate the stable cooperation between the terminal 11 and the terminal 22 and improve the assembly efficiency between the integrated terminal 20 and the terminal 11.

[0059] The forming methods of the inner layer structure 211 and the outer layer structure 212 in the present invention can include various types. For example, the inner layer structure 211 can be set as an integral structure or a split structure.

[0060] For example, in some embodiments, the inner layer structure 211 is divided into a first part and a second part, and the first part and the second part are joined together. After the first part and the second part are joined together, an inner cavity 2101 is constructed between the first part and the second part to accommodate the terminal 22. Since the first part and the second part are in a joined form, the terminal 22 can be placed between the first part and the second part during the joining process of the first part and the second part, thus facilitating the installation and positioning of the terminal 22. Among them, the first part and the second part can be fixedly connected in various ways. For example, the first part and the second part can be fixedly connected by fixing members (such as bolts, pins, rivets, etc.); or for another example, the first part and the second part can be fixedly connected by welding, bonding, etc.; in addition, after the first part and the second part are joined together, the outer layer structure 212 can be used to fixedly connect the first part and the second part together. Of course, the above description is only some embodiments of the present invention and is not a limitation on the protection scope of the present invention.

[0061] For another example, in some other embodiments, 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 installed in the inner cavity 2101. Integral forming can improve the structural strength of the inner layer structure 211, increase the service life of the integrated terminal 20, and improve the processing efficiency of the inner layer structure 211.

[0062] The inner layer structure 211 of the present invention can be set to be injection molded. Combining the foregoing embodiments, the inner layer structure 211 can be set to a split structure. For example, the inner layer structure 211 includes a first part and a second part, and the first part and the second part are assembled together after being injection molded respectively; the inner layer structure 211 can also be set to be integrally injection molded.

[0063] The inner layer structure 211 and the outer layer structure 212 in the present invention can be formed separately. For example, after the inner layer structure 211 is injection molded, the outer layer structure 212 is injection molded with the inner layer structure 211 for the second time. In this way, the position of the wiring terminal 22 can be maintained by the inner layer structure 211, preventing the wiring terminal 22 from shifting during the second injection molding process, and facilitating the provision of a deformation margin for the wiring terminal 22, which is convenient for the connection between the terminal post and the wiring terminal 22. The secondary injection molding of the outer layer structure 212 ensures the waterproof and dustproof properties of the inner layer structure 211 and the wiring terminal 22, improving the stability of the integrated terminal 20. For another example, the inner layer structure 211 includes the aforementioned first part and second part. After the first part and the second part are joined together and the wiring terminal is positioned, the outer layer structure 212 is injection molded outside the inner layer structure 211 for the second time. Of course, the inner layer structure 211 and the outer layer structure 212 can also be formed separately in other ways.

[0064] In addition, as Figure 4 and Figure 5 , the integrated terminal 20 further includes a lead wire 23. One end of the lead wire 23 is connected to the wiring terminal 22, and the other end 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. In the present invention, it is mainly described by taking the example of using the lead wire 23 to connect to a power supply to supply power to a compressor. Among them, 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 wiring terminal 22. For example, the outer layer structure 212 can be formed by injection molding. When the outer layer structure 212 is injection molded, the lead wire 23 is wrapped and fixed in the outer layer structure 212, thereby improving the sealing performance between the lead wire 23 and the terminal body 21. The specification of the lead wire 23 can be selected according to the magnitude of the current. The conductor cross-section of the lead wire 23 can be set to be not less than 4 square millimeters.

[0065] Combined with the foregoing, the manufacturing method of the integrated terminal 20 of the present invention may include: connecting the wiring terminal 22 with the lead wire 23; manufacturing an inner layer structure 211 having an inner cavity 2101, installing the wiring terminal 22 in the inner cavity 2101, and the lead wire 23 protruding; positioning the inner layer structure 211 with the wiring terminal 22 installed in a mold, and injection molding an outer layer structure 212 outside the inner layer structure 211. The outer layer structure 212 wraps the inner layer structure 211, the wiring terminal 22, and a part of the lead wire 23. During the injection molding process, a socket 2103 is constructed on the outer layer structure 212, and the socket 2103 faces the wiring terminal 22.

[0066] In some embodiments of the present invention, the inner layer structure 211 is a block made of PBT (i.e., polybutylene terephthalate) material mixed with a flame retardant; or, the outer layer structure 212 is a block made of PBT material mixed with a flame retardant. Thereby, the flame retardant performance of the terminal body can be ensured, and the stability and safety of the integrated terminal can be improved. Additionally, the inner layer structure 211 can also be set as a block made of PVC (i.e., Polyvinyl chloride) material, or a block made of nylon material; the outer layer structure 212 can also be set as a block made of PVC material, or a block made of nylon material.

[0067] In some other embodiments of the present invention, the terminal body 21 is integrally injection molded. The manufacturing process of the terminal body 21 can be simplified, and during the integral molding process of the terminal body 21, the wiring terminal 22 can be wrapped therein, thereby ensuring the waterproof and dustproof effects of the integrated terminal 20, and improving the molding efficiency and stability of the integrated terminal 20.

[0068] Combined Figures 6 to 9 , in some embodiments of the present invention, it further includes a temperature sensing component 24. The temperature sensing component 24 is installed on the terminal body 21 and has a temperature sensing surface exposed from the terminal body 21 for contacting the outer surface of the compressor 10. Integrating the temperature sensing component 24 on the terminal body 21 further improves the integration degree of the integrated terminal 20, simplifies the assembly process between the integrated terminal 20 and the compressor 10, and improves the installation efficiency of the compressor 10. After the terminal body 21 is processed, the temperature sensing component 24 can be pre-installed on the terminal body 21. When the integrated terminal 20 is connected to the compressor 10, the temperature sensing surface of the temperature sensing component 24 closely adheres to the compressor 10 to achieve temperature monitoring. The temperature sensing surface of the temperature sensing component 24 can protrude from the mating surface and directly contact the outer shell of the compressor 10.

[0069] Among them, the temperature-sensing surface and the socket 2103 can be arranged on the same side of the terminal body 21. When installing the integrated terminal 20, the terminal post 11 of the compressor 10 can pass through the socket 2103 and be electrically connected to the terminal 22. At the same time, the temperature-sensing surface contacts the outer surface of the compressor 10. At this time, by fixing the integrated terminal 20 with a fixing member, the installation of the terminal 22 and the temperature-sensing component 24 can be completed.

[0070] Optionally, as Figure 6 and Figure 7 , the terminal body 21 has an installation groove 2102. The opening of the installation groove 2102 and the socket 2103 are located on the same side of the terminal body 21, and the temperature-sensing component 24 is positioned in the installation groove 2102. The installation efficiency of the temperature-sensing component 24 can be improved.

[0071] Specifically, the terminal body 21 has a mating surface and an installation groove 2102 provided on the mating surface. The mating surface faces the housing of the compressor 10; the temperature-sensing component 24 is positioned in the installation groove 2102; a part of the connecting wire harness 27 of the temperature-sensing component 24 is located inside the terminal body 21 for electrically connecting the temperature-sensing component 24, and the other part extends out of the terminal body 21. A part of the connecting wire harness 27 is wrapped by the terminal body 21 to form a sealing structure, and the detection surface of the temperature-sensing component 24 is exposed from the mating surface. When installing the integrated terminal on the compressor, the temperature of the compressor can be detected by contacting the surface of the compressor through the detection surface.

[0072] As Figure 10 , in order to facilitate the detection of the temperature-sensing component 24, the detection surface of the temperature-sensing component 24 can protrude from the mating surface by a predetermined dimension a, and a waterproof gasket 25 is provided at the mating surface for sealing the gap between the mating surface and the compressor 10. The waterproof gasket 25 protrudes from the mating surface by a predetermined dimension t, where a ≤ t. The integrated terminal 20 is configured to be bolt-locked and connected to the compressor 10. The predetermined dimension a and the predetermined dimension t satisfy: a = 80 * t / N / Hs, where N is the locking torque of the bolt (unit: N·m, N is the value without the unit), Hs is the hardness of the waterproof gasket 25 (determined by the JIS standard, Hs is the value without the unit. 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. Optionally, a can be set to be not less than 0.2 mm and not more than 0.6 mm; or, t is not less than 0.5 mm and not more than 2.0 mm. For example, a = 0.4 mm, t = 1.0 mm. Of course, the above parameters are only some embodiments of the present invention and do not limit the protection scope of the present invention.

[0073] 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. The waterproof gasket can undergo elastic deformation under the pressure applied by the mating surface. The smaller the hardness Hs of the waterproof gasket, the greater the deformation that the waterproof gasket can undergo. At the same time, when using bolts to lock, the locking torque N also affects the thickness of the waterproof gasket.

[0074] In some embodiments of the present invention, 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 can be understood that setting the ranges of the locking torque N and the hardness Hs is beneficial to further determine the predetermined dimension a.

[0075] Combined with Figures 6 to 9 , in some embodiments, the integrated terminal 20 further includes a temperature-sensing terminal 241. The temperature-sensing terminal 241 is wrapped inside the terminal body and is opposite to the mounting groove 2102 along the normal direction of the mating surface. An opening corresponding to the temperature-sensing terminal 241 is provided on the inner surface of the mounting groove 2102. Among them, the connecting wire harness 27 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.

[0076] Similar to the foregoing, the terminal body 21 may include an inner layer structure and an outer layer structure. The temperature-sensing terminal 241 is provided in the inner layer structure, and the outer layer structure is used to wrap the inner layer structure and the temperature-sensing terminal 241. Combining the foregoing embodiments, the wiring terminal 22 is provided in the inner layer structure 211. The temperature-sensing terminal 241 may be provided in the inner layer structure 211. The outer layer structure 212 includes the inner layer structure 211, the wiring terminal 22, and the temperature-sensing terminal 241. Among them, 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 the same inner layer structure 211 or different inner layer structures. That is to say, the terminal body 21 may include one or more inner layer structures 211.

[0077] Such as Figure 5 , the integrated terminal 20 further includes a waterproof hose 26. The waterproof hose 26 is sleeved on the outer surface of the wire harness (including the aforementioned lead-out wire 23 and / or the connecting wire harness 27) and extends along the connecting wire harness 27. The waterproof hose 26 extends out of the terminal body 21 by a predetermined length. Among them, a part of the waterproof hose 26 is wrapped inside the terminal body 21; or, the waterproof hose 26 is connected to or integrally formed with the terminal body 21.

[0078] Combined with Figure 10 and Figure 13, in some embodiments of the present invention, a waterproof gasket 25 is provided at the mating surface of the terminal body 21 that mates with the compressor 10. When the integrated terminal is installed on the compressor, the mating surface can face the outer surface of the compressor, and the waterproof gasket 25 can be disposed between the mating surface and the outer surface of the compressor. By connecting the waterproof and dustproof to the terminal body 21, when the integrated terminal 20 is installed on the compressor 10, the gap between the integrated terminal 20 and the compressor 10 can be sealed, improving the waterproof and dustproof effect and stability between the integrated terminal 20 and the compressor 10.

[0079] The waterproof gasket in the present invention 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; or the waterproof gasket 25 is installed on the compressor, and then the terminal body 21 is connected to the compressor. Of course, the waterproof gasket 25 of the present invention can also be installed in other ways. In some embodiments, the waterproof gasket 25 is fixedly connected to the terminal body 21. Additionally, since the waterproof gasket 25 is fixedly connected to the terminal body 21, when the terminal body 21 is assembled with the compressor 10, it is no longer necessary to install the waterproof gasket 25 separately, thereby further simplifying the assembly efficiency of the integrated terminal 20 and the compressor 10.

[0080] The waterproof gasket 25 can be connected to the terminal body 21 in various ways. For example, the waterproof gasket 25 includes a snap structure, and a slot is provided on the side of the terminal body 21, and the assembly of the waterproof gasket 25 and the terminal body 21 is achieved by the cooperation of the snap structure and the slot; or, for example, the waterproof gasket 25 is adhesively connected to the snap structure, etc.

[0081] In some embodiments, 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 for the waterproof gasket 25 to be fixedly connected to the terminal body 21 relatively. Thus, it can facilitate the 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 improving the assembly and installation efficiency of the integrated terminal 20. Optionally, the first positioning structure is provided on the mating surface, and the second positioning structure faces and assembles with the first positioning structure along the normal direction of the mating surface.

[0082] Combined Figure 6 、 Figure 10 and Figure 13, in some embodiments, the first positioning structure includes a groove 2104, and the second positioning structure includes a boss 251 that cooperates with the groove 2104. The boss 251 is embedded and installed in the groove 2104. Among them, the boss 251 can be in interference fit with the groove 2104 to achieve stable cooperation between the boss 251 and the groove 2104, and further achieve stable connection between the waterproof gasket 25 and the terminal body 21. In addition, the thickness dimension of the boss 251 in the normal direction of the mating surface can be set to be greater than the depth dimension of the groove 2104 in the normal direction. Since the waterproof gasket 25 is a flexible structure, the elastic deformation of the waterproof gasket 25 can improve the sealing effect between the integrated terminal 20 and the compressor 10. By setting the thickness of the boss 251 to be greater than the depth of the groove 2104, the sealing effect between the terminal body 21 and the compressor 10 can be ensured when the waterproof gasket 25 elastically deforms.

[0083] Optionally, as Figure 13 , the waterproof gasket 25 includes at least one sealing portion 252. The sealing portion 252 is configured to be annular. The boss 251 is connected to the sealing portion 252 and is configured to have a shape with a variable width dimension in the radial direction of the sealing portion 252. The shape of the groove 2104 is adapted to the shape of the boss 251. The projection of the boss 251 in the normal direction of the mating surface is rectangular, trapezoidal, triangular or semi-circular.

[0084] Combined with Figure 6 and Figure 13 , in some embodiments, the terminal body 21 has a plurality of mating grooves 2104, and a plurality of bosses 251 are provided on the waterproof gasket 25. The bosses 251 are embedded and positioned in the mating grooves 2104, and the bosses 251 are in interference fit with the mating grooves 2104.

[0085] In some embodiments, the waterproof gasket 25 includes at least one sealing portion 252. The sealing portion 252 is configured to be annular. A second positioning structure or a plurality of second positioning structures arranged at intervals in the circumferential direction are provided on the sealing portion 252. The waterproof gasket 25 can be set to be integrally formed.

[0086] In addition, as Figure 13 , the waterproof gasket 25 can be set to include a connecting portion 253 and at least two sealing portions 252. The at least two sealing portions 252 are connected by the connecting portion 253.

[0087] As Figure 6, in some embodiments of the present invention, the terminal body 21 includes a rib 2105 that extends along the periphery of the mating surface. The waterproof gasket 25 includes at least one sealing portion 252 that is configured to be annular. The sealing portion 252 includes a first annular portion and a second annular portion. The first annular portion and the second annular portion are arranged along the normal direction of the mating surface. The first annular portion is embedded inside the rib 2105, and the second annular portion protrudes radially outward from the outer peripheral edge of the first annular portion and faces the rib 2105 along the normal direction. This can improve the sealing effect of the waterproof gasket 25.

[0088] As Figure 6 , in some embodiments of the present invention, the terminal body 21 includes a rib 2105 that extends along the periphery of the mating surface and constructs a drainage groove 2107 that communicates the inside and outside of the rib 2105. The terminal body 21 is provided with a mounting hole, and the drainage groove 2107 corresponds to the mounting hole. The waterproof gasket 25 constructs a channel on the mating surface that communicates the drainage groove 2107 and the mounting hole. Thus, it can facilitate the overflow of water that enters the terminal body 21 from the drainage groove 2107 and improve the waterproof and dustproof effect.

[0089] In some other embodiments of the present invention, the waterproof gasket 25 and the terminal body 21 are adhesively bonded with glue.

[0090] Combined with Figures 1 to 3 and Figure 11 , and in combination with the foregoing embodiments, the mating surface of the terminal body 21 may have a socket 2103, and the waterproof gasket 25 may include a first sealing portion arranged in a ring around the socket 2103; or, the terminal body 21 may have a mounting groove 2102, the temperature sensing component is positioned in the mounting groove 2102, and the waterproof gasket 25 includes a second sealing portion arranged in a ring around the mounting groove 2102; or, the waterproof gasket 25 may include a first sealing portion and a second sealing portion. The first sealing portion and the second sealing portion are both annular, and the connecting portion 253 connects the first sealing portion and the second sealing portion.

[0091] In some embodiments, the wiring terminal 22 is annular, U-shaped or flag-shaped. When the terminal post 11 is pressed in, it can be stably electrically connected to the wiring terminal 22, effectively improving the stability of the electrical connection between the compressor 10 and the integrated terminal 20.

[0092] Combined with Figures 14 to 17 , the compressor assembly 100 according to an embodiment of the present invention includes a compressor 10 and the integrated terminal 20 for the compressor 10 as described above. It can improve the assembly efficiency of the compressor 10, optimize the water and electricity isolation effect, and improve the operating stability of the compressor 10. On the premise of ensuring the reliability of the compressor 10, through the integrated structure, the labor cost of the air conditioner manufacturer for assembling the compressor 10 can be effectively reduced, especially for the compressor 10 exported to developed countries, this solution has obvious effects.

[0093] Combined with Figures 14 to 15 , in some embodiments, the compressor 10 is provided with positioning posts 12, and the terminal body 21 is provided with positioning holes 2106. The positioning holes 2106 penetrate through the terminal body 21. The positioning posts 12 are inserted into the positioning holes 2106, and the free ends are connected with locking members. Through the cooperation of the positioning posts 12 and the locking members, the integrated terminal 20 can be stably installed on the compressor 10. The locking members can be positioning pins, positioning screws, positioning nuts, etc.
