DETAILED DESCRIPTION

[0044] The following describes embodiments of the present invention in detail, examples of which 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 invention, and are not to be construed as limiting the present invention.

[0045] like Figures 1 to 16 According to an embodiment of the present invention, a terminal assembly 10 for a compressor 100 includes a first housing 11, which is provided with a mounting cavity 101 and a socket 102 communicating with the mounting cavity 101. The mounting cavity 101 has a first inner cavity wall 1011 and a second inner cavity wall 1012 that are opposed to each other along a first direction AA, wherein the first direction AA is perpendicular to the axis of the socket 102. Furthermore, the terminal assembly 10 also includes a terminal plug 12, which includes a main body 121 that is opposed to the socket 102. The main body 121 is disposed in the mounting cavity 101, and at least a portion of the main body 121 is disposed between the first inner cavity wall 1011 and the second inner cavity wall 1012.

[0046] The terminal assembly 10 can be arranged outside the shell 20 of the compressor 100. The compressor 100 includes a terminal 222 for connecting to a power source, and the terminal assembly 10 can be electrically connected to the terminal 222. When the terminal assembly 10 is connected to the shell 20, the terminal 222 provided on the shell 20 is pressed into the socket 102, and the terminal 222 is electrically connected to the terminal plug-in 12 in the first cover 11. During the assembly process, it is only necessary to install the terminal assembly 10 on the shell 20, and then fix the terminal assembly 10 on the shell 20. During the assembly process, the terminal 222 extends into the first cover 11 through the socket 102 and is electrically connected to the terminal plug-in 12 located in the first cover 11. The terminal plug-in 12 can be quickly and stably connected to the shell 20 and wrapped in the first cover 11 to wrap the electrical connection point between the terminal plug-in 12 and the terminal 222 through the first cover 11, thereby improving the stability of the electrical connection. The assembly efficiency of the compressor 100 can be improved, and water and electricity isolation at the electrical connection points can be achieved, thereby improving the operational 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 and others.

[0047] In combination with the above, the terminal plug-in 12 of the present invention can be used to connect a power source. A plurality of terminal plug-ins 12 can be pre-installed in the first housing 11, and the terminal plug-in 12 is adapted to the first housing 11 and fixed by the first housing 11. Figures 1 to 3 , and combined with Figure 12 and Figure 13When the terminal plug 12 is used to connect to a power source, two, three, four, or other numbers of terminal posts 222 may be provided depending on the type of the compressor 100, and a plurality of terminal plugs 12 may be provided corresponding to the terminal posts 222. The first housing 11 may include multiple mounting cavities 101 and multiple sockets 102. The multiple terminal plugs 12 correspond to the multiple mounting cavities 101, respectively. The multiple sockets 102 correspond to the multiple mounting cavities 101, respectively. The terminal plugs 12 are provided in the corresponding mounting cavities 101, and the sockets 102 communicate with the corresponding mounting cavities 101. The multiple mounting cavities 101 may be provided to communicate with each other or be separated from each other.

[0048] The first housing 11 further includes a first protrusion 1131, at least a portion of which is disposed along the first direction AA between the main body 121 and the first inner cavity wall 1011. The first protrusion 1131 can be used to position the terminal insert 12, thereby improving the positioning stability of the terminal insert 12 and facilitating multiple removal and assembly of the terminal assembly 10 from the housing 20 of the compressor 100.

[0049] According to the terminal assembly 10 for the compressor 100 according to an embodiment of the present invention, the first cover 11 can be used to protect the terminal plug-in 12, and multiple terminal plug-ins 12 can be arranged in the same first cover 11. By using the installation cavity 101 to position the terminal plug-in 12, the stability of the positioning of the terminal plug-in 12 can be improved, thereby improving the installation efficiency of the terminal assembly 10.

[0050] like Figure 7 and Figure 8 In some embodiments, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the first protrusion 1131 and the second inner cavity wall 1012 is X2, wherein 0.9≤X2 / X1≤0.97.

[0051] like Figure 14 , showing the relationship between the ratio X2 / X1 and the terminal insertion force ( Figure 14 The dotted line in the figure), and the relationship between the ratio X2 / X1 and the number of cycles ( Figure 14 ). Figure 14 As can be seen from the figure, the present invention comprehensively considers the terminal insertion force and the number of cycles by setting the ratio X2 / X1 to be greater than or equal to 0.9 and less than or equal to 0.97. This avoids the problem of a small ratio X2 / X1 resulting in a low number of cycles, and also avoids the problem of a large ratio X2 / X1 resulting in a high terminal insertion force. This facilitates the installation, maintenance, and replacement of the terminal assembly. Alternatively, the ratio X2 / X1 can be set to 0.9, 0.918, 0.94, 0.945, 0.96, or 0.97, etc.

[0052] like Figure 8 In some embodiments, in a cross section perpendicular to the axis of the socket 102, the first protrusion 1131 has a fixed end and a free end. The fixed end is connected to the first inner cavity wall 1011. The extension trend from the fixed end to the free end is defined as a first protrusion direction line, and the extension trend of the first inner cavity wall 1011 along the second direction BB is defined as the first inner cavity direction line. In a natural state (when the first protrusion 1131 is not subjected to external force), the angle α between the first protrusion direction line and the first inner cavity direction line is set to satisfy 20°≤α≤80°, and the first direction AA, the second direction BB, and the axis of the socket 102 are perpendicular to each other. By configuring the first protrusion 1131 to extend obliquely, the elastic force of the first protrusion 1131 can be enhanced, effectively positioning the terminal plug 12, facilitating deformation of the terminal plug 12 when the terminal post 222 is inserted, and facilitating the plug-in mating of the terminal post 222 with the terminal plug 12.

[0053] like Figure 15 , showing the corresponding relationship between the angle α and the terminal stress ( Figure 15 The dotted line in the figure), and the corresponding relationship between the angle α and the number of cycles ( Figure 15 ). Figure 15 As can be seen from the figure, the present invention comprehensively considers terminal stress and cycle times by setting the angle α to be greater than or equal to 20° and less than or equal to 80°, avoiding the problem of a small angle α resulting in a low cycle time and the problem of a large angle α resulting in high terminal stress, thereby facilitating the installation of the terminal assembly and facilitating maintenance and replacement of the terminal assembly. Optionally, the angle α can be set to 20°, 35°, 46°, 58.8°, 68°, or 80°, etc.

[0054] Optionally, in a cross section perpendicular to the axis of the socket 102, the first protrusion 1131 has a fixed end and a free end. The fixed end is connected to the first inner cavity wall 1011, and the free end of the first protrusion 1131 is provided with a third protrusion 1133. The third protrusion 1133 extends parallel to the sidewall of the main body 121. This facilitates the cooperation between the third protrusion 1133 and the main body 121 along the first direction AA, so that the first protrusion 1131 can provide a stable pre-tightening force for the main body 121, thereby improving the stability of the terminal assembly 10.

[0055] In addition, combined Figure 5 、 Figure 9 、 Figure 12 and Figure 13In some embodiments of the present invention, the first housing 11 further includes a second protrusion 1132. At least a portion of the second protrusion 1132 is disposed along the first direction AA between the main body 121 and the second inner cavity wall 1012. The first protrusion 1131 and the second protrusion 1132 can be used to position the terminal insert 12, thereby improving the positioning stability of the terminal insert 12 and facilitating multiple removal and assembly of the terminal assembly 10 from the casing 20 of the compressor 100.

[0056] In some embodiments, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the first protrusion 1131 and the second protrusion 1132 is X3, wherein 0.75≤X3 / X1≤0.95.

[0057] like Figure 16 , showing the relationship between the ratio X3 / X1 and the terminal insertion force ( Figure 16 The dotted line in the figure), and the relationship between the ratio X3 / X1 and the number of cycles ( Figure 16 From the attached Figure 16 As can be seen from the figure, the present invention comprehensively considers the terminal insertion force and the number of cycles by setting the ratio X3 / X1 to be greater than or equal to 0.7 and less than or equal to 0.95. This avoids the problem of a small ratio X3 / X1 resulting in a low number of cycles, and also avoids the problem of a large ratio X3 / X1 resulting in a high terminal insertion force. This facilitates the installation, maintenance, and replacement of the terminal assembly. Alternatively, the ratio X3 / X1 can be set to 0.7, 0.718, 0.74, 0.845, 0.92, or 0.95, etc.

[0058] Optionally, the minimum distance between the first inner cavity wall 1011 and the second inner cavity wall 1012 along the first direction AA is X1, and the minimum distance between the second protrusion 1132 and the first inner cavity wall 1011 is X4, wherein 0.9≤X4 / X1≤0.97.

[0059] In addition, in some embodiments, the protrusion dimension of the first protrusion 1131 relative to the first inner cavity wall 1011 is the same as the protrusion dimension of the second protrusion 1132 relative to the second inner cavity wall 1012. This can provide a stable positioning effect for the main body 121, facilitate the stable matching of the main body 121 and the socket 102, so that the terminal 222 can pass through the socket 102 and extend into the installation cavity 101 to electrically connect with the main body 121.

[0060] Additionally, in some embodiments, the first protrusion 1131 and the second protrusion 1132 are symmetrical with respect to the main body 121 .

[0061] Among them, combined Figure 5 、 Figure 9、 Figure 12 and Figure 13 In some embodiments, in a cross section perpendicular to the axis of the socket 102, the second protrusion 1132 has a fixed end and a free end. The fixed end is connected to the second inner cavity wall 1012. The extension trend from the fixed end to the free end is defined as a second protrusion direction line. The extension trend of the second inner cavity wall 1012 along the second direction BB is defined as a second inner cavity direction line. The second protrusion direction line and the second inner cavity direction line form an angle greater than zero and less than 180 degrees. The first direction AA, the second direction BB, and the axis of the socket 102 are perpendicular to each other. By configuring the second protrusion 1132 to extend obliquely, the elastic force of the second protrusion 1132 can be enhanced, effectively positioning the terminal plug 12, facilitating deformation of the terminal plug 12 when the terminal post 222 is inserted, and facilitating the plug-in mating of the terminal post 222 with the terminal plug 12.

[0062] Optionally, the angle β between the second protrusion direction line and the second inner cavity direction line is set to satisfy 20°≤β≤80°.

[0063] Optionally, the present invention comprehensively considers terminal stress and cycle times by setting the angle β to be greater than or equal to 20° and less than or equal to 80°, thereby avoiding the problem of reduced cycle times due to a too small angle β and the problem of increased terminal stress due to a too large angle β. This facilitates installation of the terminal assembly and facilitates maintenance and replacement of the terminal assembly. Optionally, the angle β can be set to 20°, 35°, 46°, 58.8°, 68°, or 80°, etc.

[0064] Optionally, in a cross section perpendicular to the axis of the socket 102, the second protrusion 1132 has a fixed end and a free end. The fixed end is connected to the second inner cavity wall 1012, and the free end of the second protrusion 1132 is provided with a fourth protrusion. The fourth protrusion extends in a direction parallel to the sidewall of the main body 121. This facilitates the engagement of the fourth protrusion with the main body 121 along the first direction AA, so that the second protrusion 1132 can provide a stable pre-tightening force for the main body 121, thereby improving the stability of the terminal assembly 10.

[0065] Optionally, the first housing 11 has a first end surface portion 103 , and the socket 102 passes through the first end surface portion 103 .

[0066] like Figure 11 In some embodiments, the main body 121 is configured as a semi-enclosed or fully enclosed ring. The main body 121 includes a first piece 1211 and a second piece 1212 that are opposite to each other along the first direction AA. The first piece 1211 and the second piece 1212 are integrally connected through a transition portion, which can simplify the structure of the main body 121 and construct a mounting hole 104 between the first piece 1211 and the second piece 1212. Figure 13, and can also facilitate the matching of the terminal 222 with the mounting hole 104. In addition, it can also facilitate the elastic deformation of the first piece 1211 and the second piece 1212 after the terminal 222 is inserted, thereby improving the stability of the assembly between the main body 121 and the terminal 222.

[0067] For example, the first piece 1211 and the second piece 1212 are opposed to each other along the first direction AA, connected at one end of the first piece 1211 and the second piece 1212 along the second direction BB by a transition portion, and separated at the other end of the first piece 1211 and the second piece 1212 along the second direction BB. Alternatively, the first piece 1211 and the second piece 1212 are opposed to each other along the first direction AA, connected at one end of the first piece 1211 and the second piece 1212 along the second direction BB by a transition portion, and connected at the other end of the first piece 1211 and the second piece 1212 along the second direction BB by a transition portion, etc. Furthermore, the terminal plug 12 further includes a wiring portion 122, which can be connected to the main body 121. Specifically, the wiring portion 122 can be connected to the first piece 1211 and / or the second piece 1212. The wiring portion 122 can also be configured to extend along the second direction BB.

[0068] The first inner cavity wall 1011 is opposite to the outer side surface of the first sheet portion 1211 , and the second inner cavity wall 1012 is opposite to the outer side surface of the second sheet portion 1212 .

[0069] Combine Figures 1 to 11 In some embodiments, the main body 121 is provided with a mounting hole 104, which is opposite to the socket 102. The terminal 222 can extend through the socket 102 into the mounting hole 104 and cooperate with the mounting hole 104 to achieve stable assembly of the terminal 222 and the terminal plug. In addition, the mounting hole 104 can be configured such that the size along the first direction AA is smaller than the size along the second direction BB, and the first direction AA, the second direction BB, and the axis of the socket 102 are perpendicular to each other. In this way, after the terminal 222 is inserted into the mounting hole 104, the size of the mounting hole 104 can be easily changed. For example, the size of the mounting hole 104 can be easily increased along the first direction AA and decreased along the second direction BB. In this way, the terminal plug 12 can achieve stable cooperation with the terminal 222, thereby improving the conductive performance.

[0070] In addition, the terminal plug 12 further includes a wiring portion 122 , which is connected to the main body 121 and extends along the second direction, so as to facilitate the connection of the terminal to the wiring harness 13 .

[0071] Combine Figure 9 、 Figure 10 、 Figure 12 and Figure 13In some embodiments of the present invention, the first housing 11 includes an inner housing 111 and an outer housing 112. The inner housing 111 is disposed within the outer housing 112, and the mounting cavity 101 is disposed within the inner housing 111. The inner housing 111 is relatively fixedly connected to the terminal plug-in 12, thereby securing and protecting the terminal plug-in 12. The outer housing 112 surrounds the inner housing 111 and the terminal plug-in 12, thereby relatively fixing the outer housing 112, the inner housing 111, and the terminal plug-in 12 together. The socket 102 is disposed on the outer housing 112, and the socket 102 faces the terminal plug-in 12. The terminal stud 222 of the compressor 100 is electrically connected to the terminal plug-in 12 through the socket 102. The terminal plug-in 12 is fixed by the inner housing 111. When the outer housing 112 surrounds the inner housing 111, the position of the terminal plug-in 12 connected to the inner housing 111 is relatively fixed, thereby preventing the terminal plug-in 12 from shifting or loosening during the docking process of the terminal assembly 10 and the housing 20, thereby improving the structural stability of the terminal assembly 10. In addition, using the outer shell 112 to wrap the inner shell 111 can facilitate the relative isolation of the inner shell 111 and the terminal plug 12 from the external environment, and facilitate the waterproof and dustproofing of the terminal plug 12.

[0072] The inner housing 111 is provided with a first interface and a second interface, wherein the first interface and the second interface are in communication with the mounting cavity 101. The first interface is used for inserting the terminal 222, and the second interface is used for leading out the wiring harness 13. The first interface can be opposite the socket 102, and the terminal 222 can pass through the socket 102 and be electrically connected to the terminal plug 12 through the first interface. In addition, the inner housing 111 can have multiple mounting cavities 101, each of which is provided with a first interface and a second interface.

[0073] In addition, a gap can be provided between the inner surface of the mounting cavity 101 and the terminal insert 12. This gap is used to provide margin for elastic deformation of the terminal insert 12 when the terminal post 222 is pressed into place, thereby facilitating insertion and electrical connection of the terminal post 222 into the terminal insert 12. For example, the terminal insert 12 can have a first piece 1211 and a second piece 1212, which are arranged opposite each other. When the terminal post 222 is pressed into place, the terminal post 222 is pressed between the first piece 1211 and the second piece 1212, causing the first piece 1211 and / or the second piece 1212 to elastically deform. By providing a gap between the inner surface of the mounting cavity 101 and the terminal insert 12, margin for deformation of the first piece 1211 and / or the second piece 1212 can be provided, thereby facilitating stable fit between the terminal post 222 and the terminal insert 12 and improving assembly efficiency between the terminal assembly 10 and the terminal post 222.

[0074] The inner shell 111 and the outer shell 112 in the present invention may be formed in various ways. For example, the inner shell 111 may be provided as an integral structure or a split structure.

[0075] For example, in some embodiments, the inner shell 111 is divided into a first part 1111 and a second part 1112, and the first part 1111 and the second part 1112 are spliced ​​together, wherein after the first part 1111 and the second part 1112 are spliced ​​together, the installation cavity 101 is provided between the first part 1111 and the second part 1112. Since the first part 1111 and the second part 1112 are in a spliced ​​form, the terminal plug-in 12 can be placed between the first part 1111 and the second part 1112 during the splicing process of the first part 1111 and the second part 1112, thereby facilitating the installation and positioning of the terminal plug-in 12. The first part 1111 and the second part 1112 can be fixedly connected in various ways. For example, the first part 1111 and the second part 1112 can be fixedly connected by fixing members (such as bolts, pins, rivets, etc.); for another example, the first part 1111 and the second part 1112 can be fixedly connected by welding, bonding, etc.; in addition, after the first part 1111 and the second part 1112 are assembled, the first part 1111 and the second part 1112 can be fixedly connected together using the housing 112. Of course, the above description only describes some embodiments of the present invention and does not limit the scope of protection of the present invention.

[0076] For example, in other embodiments, the inner housing 111 is integrally formed, wherein the inner housing 111 may have a mounting cavity 101, and the terminal plug 12 is mounted in the mounting cavity 101. Integral molding can improve the structural strength of the inner housing 111, increase the service life of the terminal assembly 10, and improve the processing efficiency of the inner housing 111.

[0077] The inner shell 111 of the present invention can be configured as an injection molded structure. In combination with the above embodiment, the inner shell 111 can be configured as a split structure, for example, the inner shell 111 includes a first portion 1111 and a second portion 1112, wherein the first portion 1111 and the second portion 1112 are separately injection molded and then assembled together; the inner shell 111 can also be configured as a single-piece injection molded structure.

[0078] The inner housing 111 and outer housing 112 of the present invention can be molded separately. For example, after the inner housing 111 is injection-molded, the outer housing 112 can be overmolded with the inner housing 111. This allows the inner housing 111 to maintain the position of the terminal insert 12, preventing the terminal insert 12 from shifting during the overmolding process. It also provides a deformation margin for the terminal insert 12, facilitating the docking of the terminal stud 222 with the terminal insert 12. The overmolding of the outer housing 112 ensures that the inner housing 111 and the terminal insert 12 are waterproof and dustproof, thereby improving the stability of the terminal assembly 10. For another example, the inner housing 111 includes the aforementioned first portion 1111 and second portion 1112. After the first portion 1111 and second portion 1112 are assembled and the terminal insert 12 is positioned, the outer housing 112 is overmolded with the inner housing 111. Of course, the inner housing 111 and outer housing 112 can also be molded separately using other methods. Optionally, the outer housing 112 surrounds the inner housing 111 by injection molding.

[0079] In addition, if Figure 5 The terminal assembly 10 further includes a wiring harness 13, one end of which is electrically connected to the terminal plug-in 12, and the other end of which extends out of the first housing 11 for connecting to external devices. For example, the wiring harness 13 can be used to connect to a power supply, a controller, etc. Figure 12 and Figure 13 The present invention is primarily described using the example of using the wiring harness 13 to connect a power source to power the compressor 100. A sealing structure can be formed between the wiring harness 13 and the housing 112 to enhance the waterproof and dustproof properties of the terminal plug 12. For example, the housing 112 can be injection molded, and during the injection molding of the housing 112, the wiring harness 13 is wrapped around and secured to the housing 112, thereby enhancing the seal between the wiring harness 13 and the first housing 11. The specifications of the wiring harness 13 can be selected based on the current, and the conductor cross-section of the wiring harness 13 can be set to be no less than 4 square millimeters.

[0080] In combination with the foregoing, the manufacturing method of the terminal assembly 10 of the present invention may include: connecting the terminal plug-in 12 with the wiring harness 13; making an inner shell 111 having a mounting cavity 101, installing the terminal plug-in 12 in the mounting cavity 101, and extending the wiring harness 13; positioning the inner shell 111 with the terminal plug-in 12 installed in the mold, and injection molding an outer shell 112 on the outside of the inner shell 111, the outer shell 112 wraps the inner shell 111, the terminal plug-in 12 and a part of the wiring harness 13, and constructing a socket 102 on the outer shell 112 during the injection molding process, and the socket 102 is opposite to the terminal plug-in 12.

[0081] In some embodiments of the present invention, the inner housing 111 is a block of PBT (polybutylene terephthalate) material mixed with a flame retardant, or the outer housing 112 is a block of PBT material mixed with a flame retardant. This ensures the flame retardancy of the first housing 11 and improves the stability and safety of the terminal assembly 10. Alternatively, the inner housing 111 can be a block of PVC (polyvinyl chloride) material or nylon material, and the outer housing 112 can be a block of PVC material or nylon material.

[0082] In other embodiments of the present invention, the first housing 11 is integrally injection molded. This simplifies the manufacturing process of the first housing 11 and allows the terminal insert 12 to be wrapped therein during the integral molding process of the first housing 11, thereby ensuring the waterproof and dustproof properties of the terminal assembly 10 and improving the molding efficiency and stability of the terminal assembly 10.

[0083] In some embodiments, the terminal assembly 10 further includes a second housing 14, a temperature sensing member 15, and an elastic member 16. The second housing 14 is provided with a mounting slot 105, the temperature sensing member 15 is disposed in the mounting slot 105, and the elastic member 16 has an elastic force that drives the temperature sensing member 15 toward the opening of the mounting slot 105. The temperature sensing surface of the temperature sensing member 15 can be in contact with the surface of the housing 20 to detect the temperature of the compressor 100. The elastic member 16 can elastically drive the temperature sensing member 15 to improve the contact stability between the temperature sensing member 15 and the surface of the housing 20, thereby improving the accuracy of the detection results.

[0084] Optionally, the first housing 11 includes an inner housing 111 and an outer housing 112, wherein the inner housing 111 is disposed within the outer housing 112, the mounting cavity 101 is disposed within the inner housing 111, and the second housing 14 is integrally formed with the outer housing 112. This can further improve the integration of the terminal assembly 10, simplify the assembly process between the terminal assembly 10 and the housing 20, and improve the installation efficiency of the compressor 100. After the terminal assembly 10 is processed, a temperature sensing component can be pre-installed on the terminal assembly 10. When the terminal assembly 10 is connected to the housing 20, the temperature sensing surface of the temperature sensing component is in close contact with the housing 20 to achieve temperature monitoring. The temperature sensing surface of the temperature sensing component can protrude from the mating surface and directly contact the housing 20.

[0085] The temperature-sensing surface and the socket 102 can be located on the same side of the first housing 11. When installing the terminal assembly 10, the terminal post 222 of the housing 20 can be inserted into the socket 102 and electrically connected to the terminal plug 12. At the same time, the temperature-sensing surface contacts the outer surface of the housing 20. At this time, the terminal assembly 10 is fixed by the fixing member to complete the installation of the terminal plug 12 and the temperature-sensing component.

[0086] The terminal assembly 10 also includes a temperature sensing terminal, which is wrapped in the second cover shell 14 and opposite to the mounting groove 105, and an opening corresponding to the temperature sensing terminal is provided on the inner surface of the mounting groove 105, wherein the connecting harness 13 is electrically connected to the temperature sensing terminal, and the wiring terminal of the temperature sensing component is electrically connected to the temperature sensing terminal.

[0087] like Figure 12 and Figure 13 The compressor 100 according to an embodiment of the present invention includes a housing 20 and the aforementioned terminal assembly 10 for the compressor 100, which is mounted on the housing 20. 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 cost of assembling the compressor 100 for air conditioner manufacturers.

[0088] In some embodiments, the housing 20 is provided with a positioning post 21, and the terminal assembly 10 is provided with a positioning hole 106. The positioning hole 106 passes through the terminal assembly 10. The positioning post 21 passes through the positioning hole 106 and a locking member 23 is connected to the free end. Through the cooperation between the positioning post 21 and the locking member 23, the terminal assembly 10 can be stably installed on the compressor 100. The locking member 23 can be a positioning pin, a positioning screw, or a positioning nut.

[0089] In other embodiments, the housing 20 is provided with an undercut structure, and the terminal assembly 10 is provided with a positioning portion. The terminal assembly 10 is pressed against the housing 20, and the undercut structure and the positioning portion are engaged with each other. Specifically, a slot can be provided on the mating surface of the terminal assembly 10, and the undercut structure can be inserted through and positioned to connect with the slot to achieve a snap connection between the terminal assembly 10 and the compressor 100. Alternatively, a slot can be provided on the side of the terminal assembly 10, and the undercut structure can be engaged with the slot to achieve stable installation of the terminal assembly 10.

[0090] Combine Figures 1 to 13 In some embodiments, the terminal assembly 10 is disposed on the outer wall of the housing 20; and / or the compressor 100 further includes a terminal 22, which includes a terminal body 221 and a terminal post 222. The terminal body 221 is disposed on the housing 20, and the terminal post 222 is connected to the terminal body 221. The terminal post 222 is disposed through the socket 102 and the terminal plug 12. This facilitates quick installation of the terminal.

[0091] Optionally, the terminal plug-in 12 is annular, U-shaped or flag-shaped. When the terminal post 222 is pressed in, it can be stably electrically connected to the terminal plug-in 12, effectively improving the stability of the electrical connection between the compressor 100 and the terminal assembly 10.

[0092] Combine Figure 6 、 Figure 12 and Figure 13 In some embodiments of the present invention, a waterproof gasket 17 is provided at the mating surface between the terminal assembly 10 and the housing 20. When the terminal assembly 10 is installed in the housing 20, the mating surface may face the outer surface of the housing 20, and the waterproof gasket 17 may be provided between the mating surface and the outer surface of the housing 20. When the terminal assembly 10 is installed in the housing 20, the gap between the terminal assembly 10 and the housing 20 can be sealed, thereby improving the waterproof and dustproof effect and stability between the terminal assembly 10 and the housing 20.

[0093] The waterproof gasket 17 in the present invention can be installed in different ways. For example, the waterproof gasket 17 is installed on the terminal assembly 10, and the terminal assembly 10 with the waterproof gasket 17 installed is connected to the housing 20; or the waterproof gasket 17 is installed on the housing 20, and then the terminal assembly 10 is connected to the housing 20. Of course, the waterproof gasket 17 of the present invention can also be installed in other ways. In some embodiments, the waterproof gasket 17 is fixedly connected to the terminal assembly 10. In addition, since the waterproof gasket 17 is fixedly connected to the terminal assembly 10, when the terminal assembly 10 is assembled with the housing 20, it is no longer necessary to install the waterproof gasket 17 separately, thereby further simplifying the assembly efficiency of the terminal assembly 10 and the housing 20.

[0094] The waterproof gasket 17 can be connected to the terminal assembly 10 in a variety of ways. For example, the waterproof gasket 17 includes a snap-on structure, and a slot is provided on the side of the terminal assembly 10, and the waterproof gasket 17 and the terminal assembly 10 are assembled by utilizing the cooperation between the snap-on structure and the slot; for another example, the waterproof gasket 17 and the snap-on structure are bonded together.
