[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0030] Combination Figures 1 to 8 According to an embodiment of the present invention, an air conditioning system 1000 includes a compressor 200, an integrated terminal 100, and a frequency converter 300. The integrated terminal 100 is mounted on the compressor 200, and the frequency converter 300 is electrically connected to the integrated terminal 100. Thus, the integrated terminal 100 can realize the electrical connection between the compressor 200 and the frequency converter 300, thereby enabling the frequency converter 300 to control or monitor the operation of the compressor 200, which helps to improve the stability of the operation of the air conditioning system 1000.

[0031] Specifically, in combination Figure 1 The integrated terminal 100 includes a power cord 11 and a temperature sensing component 12. The frequency converter 300 includes a control module 310 and a sensing module 314. The power cord 11 is electrically connected to the control module 310, and the temperature sensing component 12 is electrically connected to the sensing module 314. In other words, the integrated terminal 100 can connect the compressor 200 to the frequency converter 300, making the connection between them more convenient. Furthermore, the integrated terminal 100 also integrates the power cord 11 and the temperature sensing component 12, allowing the compressor 200 to be simultaneously connected to both the control module 310 and the sensing module 314 of the frequency converter 300, improving assembly efficiency.

[0032] Specifically, in related technologies, the compressor and inverter need to be connected via several power lines, and the temperature sensing component also needs to be separately installed on the compressor and then connected to the inverter via wires. Therefore, during assembly, the power lines, temperature sensing component, and temperature sensing component wires need to be assembled separately and then connected to the inverter separately. The assembly structure is relatively complex and difficult, resulting in low assembly efficiency and hindering cost reduction. In this application, the integrated terminal 100 integrates the power line 11 and the temperature sensing component 12. Therefore, when the integrated terminal 100 is assembled onto the compressor 200, the power line 11 and the temperature sensing component 12 can be directly connected to the compressor 200. Furthermore, the integrated terminal 100 can also be directly connected to the inverter 300, thereby enabling the inverter 300 to control and monitor the compressor 200. This simplifies the connection structure between the compressor 200 and the inverter 300 and facilitates assembly.

[0033] In other words, the air conditioning system 1000 of the present invention provides a connection system in which an integrated terminal 100 is used as a connection medium between the compressor 200 and the inverter 300. Thus, the electrical connection between the compressor 200 and the inverter 300 can be achieved simply by connecting the two ends of the integrated terminal 100 to the compressor 200 and the inverter 300 respectively. In addition, the connection between the temperature sensing component 12 and the compressor 200 and the inverter 300 can be achieved simultaneously by integrating the temperature sensing component 12 into the integrated terminal 100, which helps to improve assembly efficiency and simplify the connection structure of the air conditioning system 1000.

[0034] According to an embodiment of the present invention, the air conditioning system 1000 can realize the electrical connection between the compressor 200, the inverter 300 control module 310, and the sensing module 314 through the integrated terminal 100, thereby realizing the control and monitoring of the compressor 200. The integrated terminal 100 integrates the power line 11 and the temperature sensing component 12, which helps to simplify the connection structure and the assembly steps.

[0035] Specifically, in combination Figure 1 , Figure 2 and Figure 5In some embodiments of the present invention, the integrated terminal 100 further includes a connecting line 121. A first end of the connecting line 121 is connected to the temperature sensing component 12, and a second end is connected to the sensing module 314. This enables electrical connection between the temperature sensing component 12 and the sensing module 314, facilitating signal transmission between them. Specifically, after the integrated terminal 100 is connected to the compressor 200, the temperature sensing component 12 contacts the surface of the compressor 200, allowing it to detect the temperature of the compressor 200. The detection information from the temperature sensing component 12 can be transmitted to the sensing module 314 via the connecting line 121. The information from the sensing module 314 can be fed back to the control module 310, which can then control the compressor 200 to ensure its stable operation.

[0036] More specifically, combined Figure 4 and Figure 5 In some embodiments of the present invention, the integrated terminal 100 further includes a wiring terminal 110, which is connected to the compressor 200 and the first end of the power line 11, thereby connecting the power line 11 to the compressor 200. The second end of the power line 11 is electrically connected to the control module 310. Thus, the power line 11 can connect the compressor 200 and the control module 310. The wiring terminal 110 allows for a direct connection between the compressor 200 and the power line 11 without the need for wiring operations, facilitating quick connection, especially when the power line 11 is a three-phase power line, it can be directly connected to the compressor 200. For example, in combination with... Figure 4 According to a specific embodiment of the present invention, the compressor 200 is provided with three terminals 210, and the integrated terminal 100 has three terminals 110. When the integrated terminal 100 is assembled with the compressor 200, the three terminals 110 are directly connected to the three terminals 210, and the three terminals 210 are connected to the power cord 11. Thus, the power cord 11 can be electrically connected to the compressor 200 through the terminals 110. Furthermore, the terminal body 10 is provided with a mounting hole 104. The terminal body 10 can be installed on the compressor 200 through the mounting hole 104 via a positioning post 14. The mounting hole 104 and the positioning post 14 can be in the form of a sealed connection to improve the connection sealing performance and play a waterproof role.

[0037] Combination Figures 1 to 3 In some embodiments of the present invention, the second end of the power cord 11 has a first male connector 114, and the control module 310 has a first female connector 311, with the first male connector 114 electrically connected to the first female connector 311. Alternatively, the second end of the power cord 11 may have a first female connector 311, and the control module 310 may have a first male connector 114, with the first female connector 311 electrically connected to the first male connector 114.

[0038] In some embodiments of the present invention, the second end of the connecting line 121 has a second male connector 122, and the sensing module 314 has a second female connector 315, with the second male connector 122 and the second female connector 315 electrically connected. Alternatively, the second end of the connecting line 121 may have a second female connector 315, and the sensing module 314 may have a second male connector 122, with the second female connector 315 and the second male connector 122 electrically connected.

[0039] In other words, the integrated terminal 100 and the frequency converter 300 are electrically connected via connectors. Specifically, one end of the power cord 11 is connected to the compressor 200, and the other end is connected to the control module 310 of the frequency converter 300 via a connector; one end of the connecting wire 121 is connected to the temperature sensing component 12, and the other end is connected to the sensing module 314 of the frequency converter 300 via a connector. Therefore, by setting connectors, namely male and female connectors, the power cord 11 and the temperature sensing component 12 can be connected to their corresponding modules in the frequency converter 300, facilitating separate control and management. Furthermore, the connector structure is simple, making assembly and maintenance convenient. The connection between the male and female connectors is robust, ensuring stable electrical and communication connections. In addition, the specifications and standards of male and female connectors are universally applicable, facilitating connection between equipment from different manufacturers and improving practicality. Specifically, combined with... Figure 2 and Figure 3 The diagram shows two different plug-in structures, allowing you to choose the appropriate structure based on the specific device.

[0040] Combination Figure 1 In some embodiments of the present invention, the control module 310 includes a main control module 312 for controlling the compressor 200 and a drive module 313 for providing electrical energy. Thus, the inverter 300 can provide energy to the compressor 200 through the drive module 313 and control the compressor 200 through the main control module 312, such as adjusting the compressor 200's operating mode, thereby improving the functionality of the compressor 200. In other words, by providing a power line 11 within the integrated terminal 100, the compressor 200 and the inverter 300 can be directly connected, achieving both power supply and control simultaneously. This eliminates the need for multiple connections to the compressor 200, simplifying the structure of the air conditioning system 1000 and reducing assembly steps, thus improving assembly efficiency.

[0041] In some embodiments of the present invention, the air conditioning system 1000 may use R290 refrigerant for heat conduction (cooling or heating), which has flammable and explosive properties, thereby improving operational safety.

[0042] Furthermore, in order to further improve the stability and reliability of the air conditioning system 1000, the integrated terminal 100 in some embodiments of the present invention is also provided with a sealing structure for dust and water protection, which can block the compressor refrigerant from contacting live parts and prevent fire or explosion.

[0043] Combination Figures 6 to 8 In some embodiments of the present invention, the integrated terminal 100 includes: a terminal body 10 and a gasket, the terminal body 10 having a first positioning structure; the gasket includes a sealing portion 131 and a second positioning structure 132 connected to the sealing portion 131, the first positioning structure being connected to the second positioning structure 132, the sealing portion 131 protruding from the surface of the terminal body 10 for sealing between the integrated terminal 100 and the compressor 200.

[0044] In other words, during application, when the integrated terminal 100 is installed on the compressor 200, a gasket is provided between the integrated terminal 100 and the compressor 200. The sealing part 131 of the gasket can form a seal between the integrated terminal 100 and the compressor 200, sealing the gap between the integrated terminal 100 and the compressor 200, improving the waterproof and dustproof effect between the integrated terminal 100 and the compressor 200, and also improving the stability of assembly. The gasket also includes a second positioning structure 132. The terminal body 10 of the integrated terminal 100 includes a first positioning structure, and the second positioning structure 132 is adapted to connect with the first positioning structure, thereby realizing the connection between the gasket and the terminal body 10, so that the gasket can be stably connected to the integrated terminal 100. In this way, when the integrated terminal 100 is assembled onto the compressor 200, the gasket can directly form a seal between the integrated terminal 100 and the compressor 200, which facilitates assembly.

[0045] In practical applications, combined with Figure 2 and Figure 8 The second positioning structure 132 of the gasket can be connected to the first positioning structure of the terminal body 10, thereby allowing the gasket to be installed on the integrated terminal 100. The sealing part 131 of the gasket faces the compressor 200. When the integrated terminal 100 is installed on the compressor 200, the gasket can form a seal between the integrated terminal 100 and the compressor 200, closing the assembly gap, thereby achieving waterproof and dustproof effects and improving the structural stability after assembly and the stability during operation.

[0046] According to an embodiment of the present invention, the integrated terminal 100 is provided with a gasket. The gasket includes a sealing part 131 for improving the sealing effect and a second positioning structure 132 for connecting the housing. This can realize a sealed connection between the integrated terminal 100 and the compressor 200 and facilitate assembly.

[0047] Optionally, one or more gaskets can be provided according to actual usage needs. For example, the gaskets can be designed according to the shape of the terminal body 10 to improve the sealing effect. Alternatively, when the integrated terminal 100 also includes a second housing 16 or a third housing, multiple gaskets can be provided to be installed on the second housing 16 or the third housing respectively. In practical applications, the gaskets can be designed according to the specific structure of the integrated terminal 100, or whether a local structure of the integrated terminal 100 needs to form a seal with the compressor 200, to improve the sealing effect and simplify the structure. When multiple gaskets are provided and correspond to different housings respectively, a positioning structure can also be provided on the corresponding housing. This positioning structure is adapted to cooperate with the second positioning structure 132 to connect the gasket to the housing.

[0048] Furthermore, in some embodiments of the present invention, the first positioning structure is a rigid structure, and the second positioning structure 132 is a flexible structure. In application, the flexible structure is connected to the rigid structure. The flexible structure can improve the stability of the connection between the second positioning structure 132 and the first positioning structure. The flexible structure can fully contact the rigid structure after connection, which is beneficial for improving stability after connection. It can also achieve a seal at the connection point, thereby further improving the sealing effect. In addition, the flexible structure can reduce the requirements for manufacturing precision and installation precision of the first positioning structure, which is beneficial for reducing manufacturing costs and improving assembly efficiency.

[0049] Furthermore, the sealing portion 131 can also be a flexible structure, allowing it to achieve an elastic seal between the integrated terminal 100 and the compressor 200, thus improving the sealing effect and reducing structural requirements. Specifically, the sealing portion 131 elastically deforms to form a seal between the integrated terminal 100 and the compressor 200. In this way, when the integrated terminal 100 is assembled onto the compressor 200, the sealing portion 131 can undergo elastic deformation to achieve a sealing effect.

[0050] Optionally, the sealing part 131 and the second positioning structure 132 can be made of the same material. For example, the gasket can be manufactured as a single piece to facilitate manufacturing and improve the overall structural stability. That is, the entire gasket is a flexible structure, which can simultaneously improve the tightness of the fit and sealing effect of the connecting part and the sealing part 131.

[0051] Alternatively, the sealing part 131 and the second positioning structure 132 can also be flexible structures with different degrees of flexibility. For example, the sealing part 131 may be more flexible than the second positioning structure 132. In this way, the second positioning structure 132 may be a flexible structure with a certain degree of hardness, which can facilitate connection with the rigid first positioning structure. The sealing part 131 is more flexible, that is, softer, and can deform after assembly to better seal the assembly gap and improve the sealing effect.

[0052] Combination Figures 6 to 8 In some embodiments of the present invention, the terminal body 10 includes a first portion 10a and a second portion 10b, the second portion 10b being located inside the first portion 10a. A positioning groove 103 is formed between the first portion 10a and the second portion 10b, and the positioning groove 103 is configured as a first positioning structure. A second positioning structure 132 can be positioned within the positioning groove 103, thereby realizing the connection between the first positioning structure and the second positioning structure 132. The structure is simple and easy to assemble. Specifically, the first portion 10a and the second portion 10b can not only form a positioning groove 103 for connecting the second positioning structure 132, but also improve the overall structural stability of the terminal body 10. By setting the positioning groove 103, the second positioning structure 132 can be connected to the terminal body 10. The cooperation between the positioning groove 103 and the second positioning structure 132 can also increase the contact area between the second positioning structure 132 and the terminal body 10, improve the tightness of the connection, and improve the structural stability after the first positioning structure and the second positioning structure 132 are connected. The structure is simple and easy to assemble.

[0053] Furthermore, combined Figure 6 and Figure 7 The second positioning structure 132 is configured to extend into the positioning groove 103, thereby connecting the gasket to the terminal body 10. Specifically, during assembly, the second positioning structure 132 can be directly inserted into or embedded in the positioning groove 103 to connect the gasket, simplifying the structure and facilitating rapid assembly. Figure 8 The second positioning structure 132 can be annular to fit into the positioning groove 103.

[0054] Specifically, in an integrated terminal 100 according to a specific embodiment of the present invention, the second positioning structure 132 and the sealing portion 131 are connected along the assembly direction, and both the second positioning structure 132 and the sealing portion 131 are annular. The inner diameter of the sealing portion 131 is larger than the inner diameter of the second positioning structure 132, and the outer diameter of the sealing portion 131 is larger than the outer diameter of the second positioning structure 132. Therefore, in combination... Figure 7 The gasket has a "T" shaped cross-section. During assembly, the smaller second positioning structure 132 first extends into the positioning groove 103. After the second positioning structure 132 extends into the positioning groove 103, the sealing part 131 can seal the positioning groove 103 and cover or enclose the first part 10a of the terminal body 10, thereby improving the structural stability after assembly and improving the sealing effect.

[0055] Furthermore, combining Figure 8In some embodiments of the present invention, the outer peripheral surface of the second part 10b is provided with a first protruding rib 115, and the second positioning structure 132 elastically deforms to accommodate the first protruding rib 115, which can increase the stability of the connection between the second positioning structure 132 and the first positioning structure.

[0056] Alternatively, the inner circumferential surface of the first part 10a may be provided with a second protruding rib 116, and the second positioning structure 132 may elastically deform to accommodate the second protruding rib 116. Alternatively, both a first protruding rib 115 and a second protruding rib 116 may be provided, and the second positioning structure 132 may elastically deform to accommodate the first protruding rib 115 and the second protruding rib 116, wherein the first protruding rib 115 on the outer circumferential surface of the second part 10b and the second protruding rib 116 on the inner circumferential surface of the first part 10a may be staggered or arranged opposite to each other.

[0057] Combination Figure 5 and Figure 8 In some embodiments of the present invention, the integrated terminal 100 includes a first housing 15 and a second housing 16. A power cord 11 is disposed within the first housing 15; a temperature sensing component 12 is disposed within the second housing 16. The first housing 15 has a first wire-passing hole 101, and the second housing 16 has a second wire-passing hole 102. The power cord 11 extends from the first wire-passing hole 101, and the connecting wire 121 extends from the second wire-passing hole 102. Thus, the power cord 11 and the temperature sensing component 12 can be integrated onto the integrated terminal 100. This eliminates the need to separately install the temperature sensing component 12 during assembly, simplifying the assembly process between the terminal assembly and the compressor 200 body and improving the installation efficiency of the compressor 200 body. Specifically, after the integrated terminal 100 is processed, the temperature sensing component can be pre-installed on the housing. When the integrated terminal 100 is connected to the compressor 200, the temperature sensing surface of the temperature sensing component is in close contact with the compressor 200 to achieve temperature monitoring. The temperature sensing component 12 is connected to the sensing module 314 of the inverter 300, so that the detected temperature can be fed back to the sensing module 314, which facilitates the control module 310 and the compressor 200 to control the compressor 200, thereby keeping the temperature of the compressor 200 within a safe range.

[0058] More specifically, combined Figure 5 The temperature sensing component protrudes from the second housing 16 to contact the outer surface of the compressor 200. Integrating the temperature sensing component into the assembly further improves the integration of the terminal assembly. The temperature sensing component 12 also includes a temperature sensing terminal 123, which is enclosed within the second housing 16. The connecting wire 121 is electrically connected to the temperature sensing terminal 123, and the temperature sensing component is electrically connected to the temperature sensing terminal 123.

[0059] In some embodiments of the present invention, the power cord 11 includes a first power cord 111, a second power cord 112, and a third power cord 113. That is, the power cord 11 can be a three-phase power cord 11, which can improve operational stability and thus improve the reliability of the air conditioning system 1000.

[0060] Specifically, the operating current of the first power line 111 is less than 10 amps, and the conductor cross-sectional area of ​​the first power line 111 is 1.2–1.6 square millimeters; the operating current of the second power line 112 is less than 25 amps, and the conductor cross-sectional area of ​​the second power line 112 is 3.3–3.7 square millimeters; the operating current of the third power line 113 is less than 35 amps, and the conductor cross-sectional area of ​​the third power line 113 is 4.8–5.2 square millimeters. In other words, the connecting wire 121 of the power lines 11 can be selected with different specifications according to different operating currents, thereby improving operational stability and durability. Specifically, the larger the operating current within the power line 11, the larger the conductor cross-sectional area of ​​the selected power line 11 can be, thus improving operational stability. In practical applications, an appropriate conductor cross-sectional area of ​​the power line 11 can be selected according to the actual application and assembly conditions, thereby achieving a relatively stable and balanced state in terms of structure and function.
