Embodiments of the present invention
[0041] The embodiments of this application are described in detail below. Examples of these 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 intended to explain this application, and should not be construed as limiting this application.
[0042] As shown in Figures 1 to 12, the compressor 100 according to an embodiment of this application includes: a housing 20 and a terminal block 22; the housing 20 may house a motor unit and / or a compression unit, etc. The terminal block 22 may be disposed in the housing 20, wherein the terminal block 22 may include a terminal body 221 and a terminal post 222. The terminal body 221 is disposed in the housing 20, and the terminal post 222 is connected to the terminal body 221. The terminal block 22 may be configured to connect to a power source, wherein there may be multiple terminal posts 222, and the number or placement of the terminal posts 222 may be determined according to the type of the compressor 100. When there are multiple terminal posts 222, the multiple terminal posts 222 and the terminal posts 222 and the terminal body 221 may be mutually insulated.
[0043] Additionally, the compressor 100 may include an elastic insulator 30, which may be configured to separate the terminal body 221 and the terminal post 222, thereby achieving mutual insulation between multiple terminals 222 or between the terminal post 222 and the terminal body 221. The elastic insulator 30 is disposed on the terminal post 222 near the terminal body 221. Specifically, the elastic insulator 30 is disposed around the outside of the terminal post 222; or, in other words, the elastic insulator 30 is sleeved on the outside of the terminal post 222.
[0044] The height of the terminal 222 relative to the terminal body 221 is h1, and the height of the elastic insulator 30 relative to the terminal body 221 is h2, wherein 0.15 ≤ h2 / h1 ≤ 0.5. For example, the ratio h2 / h1 can be set to 0.15, 0.26, 0.35, 0.38, 0.41, or 0.5, etc.
[0045] Figure 13 shows the curves corresponding to the ratio h2 / h1 and the terminal breakdown voltage (dashed line in Figure 13), and the curves corresponding to the ratio h2 / h1 and the terminal temperature rise (solid line in Figure 13). As can be seen from Figure 13, when the ratio h2 / h1 is too small, although the terminal temperature rise is small, the breakdown voltage is also small, resulting in relatively poor stability of the compressor 100. When the ratio h2 / h1 is too large, although the breakdown voltage is large, the terminal temperature rise is also large, which is also detrimental to the stable operation of the compressor 100. However, when the ratio h2 / h1 is within an appropriate range, the terminal temperature rise and the terminal breakdown voltage are relatively balanced, enabling stable operation of the compressor 100.
[0046] According to the embodiments of this application, the compressor 100 can utilize the elastic insulator 30 to increase the breakdown voltage of the terminal body 221, thereby improving the operational stability of the compressor 100, extending the service life of the compressor 100, and avoiding or reducing safety hazards. Furthermore, by comprehensively considering the temperature rise and breakdown voltage of the terminal 22, the breakdown voltage of the terminal 22 can be increased while avoiding safety hazards caused by excessive temperature rise of the terminal 22, further enhancing the operational stability of the compressor 100.
[0047] Additionally, as shown in Figures 1 and 2, the compressor 100 of this application may also include a terminal assembly 10, with the terminal 222 passing through the terminal assembly 10. The terminal assembly 10 can be used to connect the terminal 222, simplifying the wiring structure of the compressor 100 and further improving the operational stability and service life of the compressor 100.
[0048] As shown in Figures 7 and 10, the terminal assembly 10 may include a first housing 11. The first housing 11 may have a mounting cavity 101 and a socket 102 communicating with the mounting cavity 101. The mounting cavity 101 has a first side and a second side opposite to each other along a first direction AA, the first direction AA being perpendicular to the axis of the socket 102. Further, the terminal assembly 10 also includes a terminal insert 12, which includes a main body portion 121 opposite to the socket 102, the main body portion 121 being disposed in the mounting cavity 101. As shown in Figure 11, the first housing 11 has a first end portion 103, through which the socket 102 passes.
[0049] Terminal assembly 10 can be located outside housing 20 and can be electrically connected to terminal block 222. When connecting to compressor 100, terminal block 222 is pressed into socket 102, and terminal block 222 is electrically connected to terminal plug 12 inside first housing 11. During assembly, terminal assembly 10 only needs to be installed onto housing 20 and then fixed to housing 20. During assembly, terminal block 222 extends through socket 102 into first housing 11 and is electrically connected to terminal plug 12 located inside first housing 11. Terminal plug 12 can quickly and stably connect to housing 20 and is enclosed in first housing 11, thereby improving the stability of the electrical connection by enclosing the electrical connection point between terminal plug 12 and terminal block 222 through first housing 11. This improves the assembly efficiency of compressor 100, achieves water and electricity isolation at the electrical connection point, and improves the operational stability of compressor 100. While ensuring the reliability of compressor 100, the integrated structure can effectively reduce the labor costs of air conditioner manufacturers assembling compressor 100. This solution is particularly effective for compressor 100 exported to developed countries.
[0050] In conjunction with the foregoing, the terminal plug 12 in this application can be used to connect to a power source. Multiple terminal plugs 12 can be pre-installed within the first housing 11, with the terminal plugs 12 adapted to the first housing 11 and fixed by the first housing 11. As shown in Figures 3 and 5, when the terminal plug 12 is used to connect to the power source, two, three, four, or other numbers of terminals 222 can be provided depending on the type of compressor 100, and multiple terminal plugs 12 can be configured corresponding to multiple terminals 222. The first housing 11 can include multiple mounting cavities 101 and multiple sockets 102. Multiple terminal plugs 12 correspond to multiple mounting cavities 101, and multiple sockets 102 correspond to multiple mounting cavities 101. The terminal plug 12 is located in the corresponding mounting cavity 101, and the socket 102 communicates with the corresponding mounting cavity 101. The multiple mounting cavities 101 can be interconnected or separated from each other.
[0051] As shown in Figures 2 and 4, the terminal plug 12 is located inside the first housing 11, and the terminal post 222 passes through the terminal plug 12. The minimum insertion depth of the terminal post 222 into the terminal plug 12 is h3, where 0.1 ≤ h3 / h1 ≤ 0.8. For example, the ratio h3 / h1 can be set to 0.1, 0.14, 0.35, 0.47, 0.58, or 0.8, etc.
[0052] Figure 14 shows the relationship curves between the ratio h3 / h1 and the terminal insertion force (dashed line in Figure 14), and the relationship between the ratio h3 / h1 and the terminal temperature rise (solid line in Figure 14). As can be seen from Figure 14, when the ratio h3 / h1 is too small, although the terminal insertion force is small, the terminal temperature rise is large, resulting in relatively poor stability of the compressor 100. When the ratio h3 / h1 is too large, although the terminal temperature rise is small, the terminal insertion force is large, which is not conducive to the installation of the terminal assembly 10. However, when the ratio h2 / h1 is within an appropriate range, the terminal temperature rise and terminal breakdown voltage are relatively balanced, enabling stable operation of the compressor 100 and facilitating the installation of the terminal assembly 10, thus improving the installation efficiency of the terminal assembly 10.
[0053] Referring to Figures 7, 10, and 12, 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 pass through the socket 102 and the mounting hole 104. For example, the terminal 222 can pass through the socket 102 and extend into the mounting hole 104, and cooperate with the mounting hole 104 to achieve a stable assembly of the terminal 222 and the terminal insert. Alternatively, 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 axes of the first direction AA, the second direction BB, and the socket 102 are perpendicular to each other. This allows the size of the mounting hole 104 to change after the terminal 222 is inserted into it; for example, the size of the mounting hole 104 can increase along the first direction AA and decrease along the second direction BB. This ensures a stable fit between the terminal insert 12 and the terminal 222, improving conductivity.
[0054] In addition, the terminal plug-in 12 also includes a wiring section 122, which is connected to the main body 121. This facilitates the connection of the terminal plug-in to the wiring harness 13.
[0055] As shown in Figure 6, in some embodiments, the diameter of the terminal 222 is D1, and the minimum width of the projection of the elastic insulating element along the axis of the terminal 222 is D2, where 1.5 ≤ D2 / D1 ≤ 3.5. For example, the ratio D2 / D1 can be set to 1.5, 1.65, 2.35, 2.38, 3.41, or 3.5, etc. Through the above limitations, the electrical isolation effect between the terminal 222 and the terminal body, and between the terminal 222 and the housing 20, can be further improved, the creepage distance can be increased, the breakdown voltage of the compressor 100 can be further improved, and the operational stability and service life of the compressor 100 can be enhanced.
[0056] Optionally, the elastic insulator 30 includes a base 31 and a post 32. The base 31 is connected to one end of the post 32, and the periphery of the base 31 extends beyond the outer peripheral surface of the post 32. The base 31 is stacked on the terminal body 221, and the post 32 is sleeved on the terminal post 222. This can increase the creepage distance and improve the breakdown voltage, thereby improving the operational stability and service life of the compressor 100.
[0057] As shown in Figure 6, there are multiple terminals 222, and multiple elastic insulators 30 corresponding to the terminals 222 respectively. The bases 31 of the multiple elastic insulators 30 are arranged side by side and connected. The multiple elastic insulators 30 in the machine room can be set as an integrated structure, which facilitates the molding and installation of the elastic insulators 30 and improves the assembly efficiency of the compressor 100.
[0058] As shown in Figures 2, 7, and 8, in some embodiments of this application, 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 12, serving to fix and protect the terminal plug 12. The outer housing 112 encloses the inner housing 111 and the terminal plug 12, thereby relatively fixing the outer housing 112, the inner housing 111, and the terminal plug 12 together. The socket 102 is disposed on the outer housing 112 and is opposite to the terminal plug 12, for the terminal post 222 to pass through the socket 102 and electrically connect to the terminal plug 12. The inner housing 111 can fix the terminal plug 12. When the outer housing 112 encloses the inner housing 111, it can ensure that the position of the terminal plug 12 connected to the inner housing 111 is relatively fixed, avoiding the problem of displacement or loosening of the terminal plug 12 during the docking of the terminal assembly 10 and the housing 20, thereby improving the structural stability of the terminal assembly 10. In addition, by using the outer shell 112 to enclose the inner shell 111, it is possible to relatively isolate the inner shell 111 and the terminal plug 12 from the external environment, which facilitates the waterproofing and dustproofing of the terminal plug 12.
[0059] The inner shell 111 is provided with a first interface and a second interface, which are connected to the mounting cavity 101. The first interface is used for inserting the terminal block 222, and the second interface is used for leading out the wire harness 13. The first interface can be opposite to the socket 102, and the terminal block 222 can pass through the socket 102 and the first interface to be electrically connected to the terminal plug 12. In addition, the inner shell 111 may have multiple mounting cavities 101, each of which is provided with a corresponding first interface and a second interface.
[0060] Additionally, a gap can be provided between the inner surface of the mounting cavity 101 and the terminal plug 12. This gap provides allowance for elastic deformation of the terminal plug 12 when the terminal post 222 is pressed in, thereby facilitating the insertion and electrical connection of the terminal post 222 to the terminal plug 12. For example, the terminal plug 12 may have a first portion 1211 and a second portion 1212, which are arranged opposite to each other. When the terminal post 222 is pressed in, it is pressed between the first portion 1211 and the second portion 1212, and the first portion 1211 and / or the second portion 1212 will undergo elastic deformation. By providing a gap between the inner surface of the mounting cavity 101 and the terminal plug 12, allowance can be provided for the deformation of the first portion 1211 and / or the second portion 1212, so as to facilitate a stable fit between the terminal post 222 and the terminal plug 12 and improve the assembly efficiency between the terminal assembly 10 and the terminal post 222.
[0061] The inner shell 111 and outer shell 112 in this application can be formed in various ways. For example, the inner shell 111 can be set as an integral structure or as a split structure.
[0062] For example, as shown in Figure 2, in some embodiments, the inner shell 111 is divided into a first part 1111 and a second part 1112. The first part 1111 and the second part 1112 are assembled together. After the first part 1111 and the second part 1112 are assembled together, the mounting cavity 101 is located between the first part 1111 and the second part 1112. Since the first part 1111 and the second part 1112 are assembled together, the terminal plug 12 can be placed between the first part 1111 and the second part 1112 during the assembly process, thereby facilitating the installation and positioning of the terminal plug 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 fasteners (such as bolts, pins, rivets, etc.); or 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 outer shell 112 can be used to fix the first part 1111 and the second part 1112 together. Of course, the above description is only some embodiments of this application and is not a limitation on the scope of protection of this application.
[0063] For example, in other embodiments, the inner shell 111 is integrally formed, wherein the inner shell 111 may have a mounting cavity 101 in which the terminal plug 12 is mounted. Integral forming can improve the structural strength of the inner shell 111, increase the service life of the terminal assembly 10, and improve the processing efficiency of the inner shell 111.
[0064] The inner shell 111 of this application can be configured as injection molded. In conjunction with the foregoing embodiments, the inner shell 111 can be configured as a split structure, for example, the inner shell 111 includes a first part 1111 and a second part 1112, wherein the first part 1111 and the second part 1112 are separately injection molded and then assembled together; the inner shell 111 can also be configured as a single injection molded unit.
[0065] In this application, the inner shell 111 and the outer shell 112 can be molded separately. For example, after the inner shell 111 is injection molded, the outer shell 112 can be injection molded together with the inner shell 111. This allows the inner shell 111 to maintain the position of the terminal plug 12, preventing the terminal plug 12 from shifting during the secondary injection molding process. It also provides deformation allowance for the terminal plug 12, facilitating the connection between the terminal post 222 and the terminal plug 12. The secondary injection molding of the outer shell 112 ensures that the inner shell 111 and the terminal plug 12 are waterproof and dustproof, improving the stability of the terminal assembly 10. Alternatively, the inner shell 111 may include the aforementioned first part 1111 and second part 1112. After the first part 1111 and the second part 1112 are assembled and the terminal plug 12 is positioned, the outer shell 112 is injection molded around the inner shell 111. Of course, the inner shell 111 and the outer shell 112 can also be molded separately in other ways. Optionally, the outer shell 112 surrounds the inner shell 111 by injection molding.
[0066] Additionally, as shown in Figure 1, the terminal assembly 10 also includes a wiring harness 13. One end of the wiring harness 13 is electrically connected to the terminal plug 12, and the other end extends out of the first housing 11 for connecting external devices. For example, the wiring harness 13 can be used to connect a power supply, controller, etc. This application mainly uses the example of using the wiring harness 13 to connect a power supply to power the compressor 100. A sealing structure can be formed between the wiring harness 13 and the housing 112 to improve the waterproof and dustproof effect 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 and fixed to the housing 112, thereby improving the sealing between the wiring harness 13 and the first housing 11. The specifications of the wiring harness 13 can be adjusted according to the current magnitude, and the conductor cross-section of the wiring harness 13 can be set to be no less than square millimeters.
[0067] In conjunction with the foregoing, the manufacturing method of the terminal assembly 10 of this application may include: connecting the terminal plug 12 to the wire harness 13; manufacturing an inner shell 111 having a mounting cavity 101, installing the terminal plug 12 in the mounting cavity 101, with the wire harness 13 extending out; positioning the inner shell 111 with the terminal plug 12 installed in a mold, and injection molding an outer shell 112 on the outside of the inner shell 111, the outer shell 112 enclosing the inner shell 111, the terminal plug 12, and a portion of the wire harness 13, and constructing a socket 102 on the outer shell 112 during the injection molding process, the socket 102 being opposite to the terminal plug 12.
[0068] In some embodiments of this application, the inner shell 111 is a block made of PBT (polybutylene terephthalate) material mixed with flame retardant; or, the outer shell 112 is a block made of PBT material mixed with flame retardant. This ensures the flame-retardant performance of the first shell 11 and improves the stability and safety of the terminal assembly 10. Alternatively, the inner shell 111 can also be a block made of PVC (polyvinyl chloride) material or nylon material; the outer shell 112 can also be a block made of PVC material or nylon material.
[0069] In some other embodiments of this application, the first housing 11 is integrally injection molded. This simplifies the manufacturing process of the first housing 11, allowing the terminal insert 12 to be enclosed within it during the integral molding process, thereby ensuring the waterproof and dustproof effect of the terminal assembly 10 and improving the molding efficiency and stability of the terminal assembly 10.
[0070] As shown in Figures 7 and 9, in some embodiments, the terminal assembly 10 further includes a second housing 14, a temperature sensing element 15, and an elastic element 16. The second housing 14 is provided with a mounting groove 105, the temperature sensing element 15 is disposed in the mounting groove 105, and the elastic element 16 has an elastic force that drives the temperature sensing element 15 through an opening facing the mounting groove 105. The temperature sensing surface of the temperature sensing element 15 can be fitted against the surface of the housing 20 to achieve temperature detection of the compressor 100. The elastic element 16 can elastically drive the temperature sensing element 15 to improve the contact stability between the temperature sensing element 15 and the surface of the housing 20, thereby improving the accuracy of the detection results.
[0071] Optionally, the first housing 11 includes an inner housing 111 and an outer housing 112, with the inner housing 111 disposed within the outer housing 112 and the mounting cavity 101 disposed within the inner housing 111. The second housing 14 is integrally formed with the outer housing 112. This further improves the integration of the terminal assembly 10 and simplifies the assembly process between the terminal assembly 10 and the housing 20, thereby improving 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.
[0072] 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 can pass through the socket 102 and electrically connect 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 can be fixed by the fastener, and the installation of the terminal plug 12 and the temperature-sensing component can be completed.
[0073] The terminal assembly 10 also includes a temperature sensing terminal, which is enclosed in the second housing 14 and is opposite to the mounting groove 105. The inner surface of the mounting groove 105 is provided with an opening corresponding to the temperature sensing terminal. The connecting wire 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.
[0074] Referring to Figures 1 and 7, 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, which penetrates the terminal assembly 10. The positioning post 21 passes through the positioning hole 106 and its free end is connected to a locking member 23. Through the cooperation of the positioning post 21 and the locking member 23, the terminal assembly 10 can be stably installed on the housing 20. The locking member 23 can be a positioning pin, a positioning screw, or a positioning nut, etc.
[0075] In other embodiments, the housing 20 is provided with an undercut structure, and the terminal assembly 10 is provided with a positioning part. The terminal assembly 10 is pressed against the housing 20 and engaged by the undercut structure and the positioning part. Specifically, a slot can be provided on the mating surface of the terminal assembly 10, through which the undercut structure passes and is positioned and connected to the slot, thereby achieving a snap-fit connection between the terminal assembly 10 and the housing 20. Alternatively, a slot can be provided on the side of the terminal assembly 10, and the engagement of the undercut structure with the slot can achieve stable installation of the terminal assembly 10.
[0076] Referring to Figure 2, in some embodiments of this application, the compressor further includes a waterproof gasket, at least a portion of which is disposed between the terminal assembly and the housing. Specifically, a waterproof gasket 17 is provided at the mating surface where the terminal assembly 10 mates with the housing. When the terminal assembly 10 is installed on the housing 20, the mating surface may face the outer surface of the housing 20, and the waterproof gasket 17 may be disposed between the mating surface and the outer surface of the housing 20. This allows the gap between the terminal assembly 10 and the housing 20 to be sealed when the terminal assembly 10 is installed on the housing 20, improving the waterproof and dustproof effect and stability between the terminal assembly 10 and the housing 20.
[0077] The waterproof gasket 17 in this application can be installed in different ways. For example, the waterproof gasket 17 can be installed onto the terminal assembly 10, and the terminal assembly 10 with the waterproof gasket 17 installed can be connected to the housing 20; or the waterproof gasket 17 can be installed on the housing 20, and then the terminal assembly 10 can be connected to the housing 20. Of course, the waterproof gasket 17 in this application 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, it is no longer necessary to install the waterproof gasket 17 separately when assembling the terminal assembly 10 and the housing 20, thereby further simplifying the assembly efficiency of the terminal assembly 10 and the housing 20.
[0078] The waterproof gasket 17 can be connected to the terminal assembly 10 in various ways. For example, the waterproof gasket 17 includes a snap-fit structure and a slot is provided on the side of the terminal assembly 10. The waterproof gasket 17 and the terminal assembly 10 are assembled by the cooperation of the snap-fit structure and the slot. Another example is that the waterproof gasket 17 and the snap-fit structure are bonded together.
[0079] As shown in Figure 1, in some embodiments, the terminal assembly 10 is disposed on the outer wall surface of the housing 20. This facilitates the quick installation of the terminal assembly.
[0080] Optionally, the terminal plug 12 can be ring-shaped, U-shaped, or flag-shaped. When the terminal block 222 is pressed in, it can stably connect with the terminal plug 12, effectively improving the stability of the electrical connection between the terminal block and the terminal assembly 10.
[0081] As shown in Figures 13 and 14, in some embodiments, the main body 121 is configured as a semi-closed or fully closed ring. The main body 121 includes a first piece 1211 and a second piece 1212 facing each other along a first direction AA. The first piece 1211 and the second piece 1212 are integrally connected by a transition portion. This simplifies the structure of the main body 121 and allows for the construction of a mounting hole 104 between the first piece 1211 and the second piece 1212, facilitating the mating of the terminal 222 with the mounting hole 104. Furthermore, it facilitates the elastic deformation of the first piece 1211 and the second piece 1212 after the terminal 222 is inserted, improving the stability of the assembly between the main body 121 and the terminal 222.
[0082] For example, the first piece 1211 and the second piece 1212 are opposite each other along the first direction AA, and one end of the first piece 1211 and the second piece 1212 along the second direction BB are connected by a transition portion, while the other ends of the first piece 1211 and the second piece 1212 along the second direction BB are separated; or, the first piece 1211 and the second piece 1212 are opposite each other along the first direction AA, and one end of the first piece 1211 and the second piece 1212 along the second direction BB are connected by a transition portion, while the other ends of the first piece 1211 and the second piece 1212 along the second direction BB are connected by a transition portion, etc. In addition, the terminal plug 12 also includes a wiring portion 122, which can be connected to the main body portion 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.
