The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Combination Figures 1 to 8 According to the embodiment of the utility model, the air conditioning system 1000 includes: a compressor 200, an integrated terminal 100 and an inverter 300. The integrated terminal 100 is installed on the compressor 200, and the inverter 300 is electrically connected to the integrated terminal 100. Therefore, the integrated terminal 100 can realize the electrical connection between the compressor 200 and the inverter 300, so as to realize the control or monitoring of the operation of the compressor 200 by the inverter 300, which is beneficial to improve the stability of the operation of the air conditioning system 1000.

In other words, the integrated terminal 100 can connect the compressor 200 with the inverter 300, making the connection between the compressor 200 and the inverter 300 more convenient. In addition, the power line 11 and the temperature sensing component 12 are also integrated in the integrated terminal 100, so that the compressor 200 can be connected to the control module 310 and the sensor module 314 of the inverter 300 at the same time, thereby improving the assembly efficiency.

[0032] Specifically, in the related art, the compressor and the inverter need to be connected through several power lines, and the temperature sensing component also needs to be installed separately on the compressor, and then the temperature sensing component is connected to the inverter through wires. Therefore, during assembly, the power line, the temperature sensing component, and the temperature sensing component wire need to be assembled separately, and then connected to the inverter separately. The assembly structure is relatively complex and the assembly difficulty is relatively large, resulting in low assembly efficiency, which is not conducive to reducing costs. In the present application, the power line 11 and the temperature sensing component 12 are integrated in the integrated terminal 100. Therefore, when the integrated terminal 100 is assembled on 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, so as to realize the control and monitoring of the compressor 200 by the inverter 300, which can simplify the connection structure between the compressor 200 and the inverter 300 and facilitate assembly.

[0033] That is to say, the air-conditioning system 1000 of the utility model provides a connection system, that is, the integrated terminal 100 is used as a connection medium between the compressor 200 and the inverter 300. Therefore, it is only necessary to connect the two ends of the integrated terminal 100 to the compressor 200 and the inverter 300 respectively to achieve the electrical connection between the compressor 200 and the inverter 300. In addition, by integrating the temperature sensing component 12 in the integrated terminal 100, the connection between the temperature sensing component 12 and the compressor 200 and the inverter 300 can be achieved at the same time, which is beneficial to improve the assembly efficiency and simplify the connection structure of the air-conditioning system 1000.

[0034] According to the air conditioning system 1000 of the embodiment of the utility model, the electrical connection between the compressor 200 and the inverter 300 control module 310 and the sensor module 314 can be achieved through the integrated terminal 100, so as to realize the control and monitoring of the compressor 200, and the power cord 11 and the temperature sensing component 12 are integrated in the integrated terminal 100, which is conducive to simplifying the connection structure and simplifying the assembly steps.

[0035] Specifically, combined Figure 1 , Figure 2 and Figure 5In some embodiments of the present invention, the integrated terminal 100 further includes a connecting wire 121, a first end of the connecting wire 121 is connected to the temperature sensing component 12, and a second end is connected to the sensor module 314, thereby realizing electrical connection between the temperature sensing component 12 and the sensor module 314, and facilitating signal transmission between the temperature sensing component 12 and the sensor module 314. Specifically, after the integrated terminal 100 is connected to the compressor 200, the temperature sensing component 12 contacts the surface of the compressor 200, and the temperature of the compressor 200 can be detected. The detection information of the temperature sensing component 12 can be transmitted to the sensor module 314 through the connecting wire 121, and the information of the sensor module 314 can be fed back to the control module 310, and the control module 310 can control the compressor 200, thereby ensuring the stable operation of the compressor 200.

[0036] More specifically, combined with Figure 4 and Figure 5 In some embodiments of the utility model, the integrated terminal 100 further includes a wiring terminal 110, and the wiring terminal 110 is connected to the compressor 200 and the first end of the power cord 11, so as to realize the connection between the power cord 11 and the compressor 200, and the second end of the power cord 11 is electrically connected to the control module 310, thereby, the power cord 11 can connect the compressor 200 and the control module 310. Among them, the wiring terminal 110 can realize the direct connection between the compressor 200 and the power cord 11, without the need for wiring operation, and is convenient for quick connection, especially when the power cord 11 is a three-phase power cord 11, the power cord 11 can be directly connected to the compressor 200. For example, in combination Figure 4 According to a specific embodiment of the utility model, 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 line 11, so that the power line 11 can be electrically connected to the compressor 200 through the terminals 110. Further, the terminal body 10 is provided with a mounting hole 104, and the terminal body 10 can be installed on the compressor 200 through the positioning column 14 passing through the mounting hole 104, wherein the mounting hole 104 and the positioning column 14 can be in the form of a sealed connection, thereby improving the connection sealing and playing 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, the control module 310 has a first female connector 311, and the first male connector 114 is electrically connected to the first female connector 311. Alternatively, the second end of the power cord 11 has a first female connector 311, the control module 310 has a first male connector 114, and the first female connector 311 is 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, the sensor module 314 has a second female connector 315, and the second male connector 122 is electrically connected to the second female connector 315. Alternatively, the second end of the connecting line 121 has a second female connector 315, the sensor module 314 has a second male connector 122, and the second female connector 315 is electrically connected to the second male connector 122.

[0039] That is to say, the integrated terminal 100 is electrically connected to the inverter 300 through a plug-in connector. 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 inverter 300 through a plug-in connector; one end of the connecting line 121 is connected to the temperature sensing component 12, and the other end is connected to the sensor module 314 of the inverter 300 through a plug-in connector. Therefore, by setting a plug-in connector, that is, a male connector and a female connector, the power cord 11 and the temperature sensing component 12 can be connected to the corresponding modules in the inverter 300 respectively, which is convenient for separate control and management, and the structure of the plug-in connection is simple, which is convenient for plugging and unplugging during assembly and maintenance. The connection between the male connector and the female connector is stable, which can ensure stable electrical connection and communication connection. In addition, the specifications and standards of the male and female connections are generally applicable, which facilitates the connection between equipment from different manufacturers and improves practicality. Specifically, combined with Figure 2 and Figure 3 , two different plug-in structures are shown respectively, and the appropriate plug-in structure can be selected according to different devices.

[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 electric energy, whereby the inverter 300 can provide energy for the operation of the compressor 200 through the drive module 313, and control the compressor 200 through the main control module 312, such as the operation mode of the compressor 200, which is conducive to improving the functionality of the compressor 200. That is, by arranging the power line 11 in the integrated terminal 100, the compressor 200 and the inverter 300 can be directly connected, and the effects of power supply and control can be achieved at the same time, so that the compressor 200 does not need to be connected multiple times, which is conducive to simplifying the structure of the air-conditioning system 1000, and can also reduce the assembly steps, which is conducive to improving the 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), and the refrigerant has flammable and explosive properties, thereby improving operational safety.

[0042] Furthermore, in order to further improve the stability and reliability of the operation of the air-conditioning system 1000, the integrated terminal 100 of some embodiments of the utility model is also provided with a sealing structure for dustproof and waterproof effects, which can block the contact between the compressor refrigerant and the live parts to avoid fire or explosion.

[0043] Combination Figures 6 to 8 In some embodiments of the utility model, the integrated terminal 100 includes: a terminal body 10 and a gasket, the terminal body 10 has 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 is connected to the second positioning structure 132, the sealing portion 131 protrudes from the surface of the terminal body 10, and is used for sealing between the integrated terminal 100 and the compressor 200.

[0044] That is to say, when the integrated terminal 100 is installed on the compressor 200, a gasket is provided between the integrated terminal 100 and the compressor 200, and the sealing portion 131 of the gasket can form a seal between the integrated terminal 100 and the compressor 200, and can seal the gap between the integrated terminal 100 and the compressor 200, thereby improving the waterproof and dustproof effect between the integrated terminal 100 and the compressor 200, and can also improve the stability of assembly. The gasket also includes a second positioning structure 132, and the terminal body 10 of the integrated terminal 100 includes a first positioning structure, and the second positioning structure 132 is suitable for connecting with the first positioning structure, so as to realize the connection between the gasket and the terminal body 10, so that the gasket can be stably connected to the integrated terminal 100, so that when the integrated terminal 100 is assembled on the compressor 200, the gasket can directly form a seal between the integrated terminal 100 and the compressor 200, which is convenient for assembly.

[0045] In practical application, 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, so that the gasket can be installed on the integrated terminal 100, and the sealing portion 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 a waterproof and dustproof effect, and improving the structural stability after assembly and the stability during operation.

[0046] According to the integrated terminal 100 of the embodiment of the utility model, a gasket is arranged on the integrated terminal 100, and the gasket includes a sealing portion 131 for improving the sealing effect and a second positioning structure 132 for connecting the shell, which can realize the 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 use needs. For example, the gasket can be provided according to the shape of the terminal body 10 to improve the sealing effect. Alternatively, when the integrated terminal 100 also includes a second shell 16 or a third shell, multiple gaskets can be provided to be installed on the second shell 16 or the third shell. In actual application, how to set the gasket can be determined according to the specific structure of the integrated terminal 100, or whether the local structure of the integrated terminal 100 needs to form a seal with the compressor 200, so as to improve the sealing effect and simplify the structure. When multiple gaskets are provided and correspond to different shells respectively, a positioning structure can also be provided on the corresponding shell, and the positioning structure is suitable for cooperating with the second positioning structure 132 to connect the gasket to the shell.

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

[0049] Furthermore, the sealing portion 131 may also be a flexible structure, so that the sealing portion 131 can achieve elastic sealing between the integrated terminal 100 and the compressor 200, which is conducive to improving the sealing effect and has low 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 on the compressor 200, the sealing portion 131 can be elastically deformed to achieve a sealing effect.

[0050] Optionally, the sealing portion 131 and the second positioning structure 132 can be made of the same material, for example, the liner can be manufactured in one piece, which is convenient for manufacturing and can also improve the overall structural stability. That is, the entire liner is a flexible structure, which can simultaneously improve the matching tightness and sealing effect of the connecting portion and the sealing portion 131.

[0051] Optionally, the sealing portion 131 and the second positioning structure 132 may also be flexible structures with different degrees of flexibility. For example, the flexibility of the sealing portion 131 is greater than the flexibility of the second positioning structure 132. In this way, the second positioning structure 132 may be a flexible structure with a certain hardness, which can facilitate connection with the first positioning structure of the hard structure. The sealing portion 131 is more flexible, that is, softer, and can be deformed 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 utility model, the terminal body 10 includes a first part 10a and a second part 10b, the second part 10b is located inside the first part 10a, and a positioning groove 103 is formed between the first part 10a and the second part 10b, and the positioning groove 103 is configured as a first positioning structure. The second positioning structure 132 can be positioned in the positioning groove 103, so as to realize the connection between the first positioning structure and the second positioning structure 132, and the structure is simple and easy to assemble. Specifically, the first part 10a and the second part 10b can form the positioning groove 103 for connecting the second positioning structure 132, and can 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, and the positioning groove 103 cooperates with the second positioning structure 132 to 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, and the structure is simple and easy to assemble.

[0053] Furthermore, combined with Figure 6 and Figure 7 The second positioning structure 132 is configured to be suitable for extending into the positioning groove 103, so that the gasket can be connected to the terminal body 10. Specifically, during assembly, the second positioning structure 132 can be directly inserted or embedded into the positioning groove 103 to achieve the connection of the gasket, which is conducive to simplifying the structure and facilitating rapid assembly. Figure 8 The second positioning structure 132 may be annular so as to be suitable for extending into the positioning groove 103 .

[0054] Specifically, according to an integrated terminal 100 of a specific embodiment of the utility model, the second positioning structure 132 is connected to the sealing portion 131 along the assembly direction, and the second positioning structure 132 and the sealing portion 131 are both 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 cross section of the gasket is a "T" shaped structure. During assembly, the second positioning structure 132 with a smaller size first extends into the positioning groove 103. After the second positioning structure 132 extends into the positioning groove 103, the sealing portion 131 can block the positioning groove 103 and cover or envelop the first portion 10a of the terminal body 10, thereby improving the structural stability after assembly and improving the sealing effect.

[0055] Furthermore, combined with Figure 8In some embodiments of the present invention, a first rib 115 is disposed on the outer circumference of the second portion 10b, and the second positioning structure 132 is elastically deformed to accommodate the first 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 circumference of the first portion 10a is provided with a second convex rib 116, and the second positioning structure 132 is elastically deformed to accommodate the second convex rib 116. Alternatively, the first convex rib 115 and the second convex rib 116 are provided at the same time, and the second positioning structure 132 is elastically deformed to accommodate the first convex rib 115 and the second convex rib 116, wherein the first convex rib 115 on the outer circumference of the second portion 10b and the second convex rib 116 on the inner circumference of the first portion 10a can be staggered or arranged relative to each other.

[0057] Combination Figure 5 and Figure 8 In some embodiments of the utility model, the integrated terminal 100 includes a first shell 15 and a second shell 16, wherein a power line 11 is arranged in the first shell 15; a temperature sensing component 12 is arranged in the second shell 16; the first shell 15 has a first wire hole 101, and the second shell 16 has a second wire hole 102, the wire harness of the power line 11 extends from the first wire hole 101, and the wire harness of the connecting line 121 extends from the second wire hole 102, thereby, the power line 11 and the temperature sensing component 12 can be integrated into the integrated terminal 100. In this way, it is not necessary to separately install the temperature sensing component 12 during assembly, which can simplify the assembly process between the terminal assembly and the compressor 200 body, and improve 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 close to the compressor 200 to achieve temperature monitoring. The temperature sensing component 12 is connected to the sensor module 314 of the inverter 300, so that the detected temperature can be fed back to the sensor module 314, which is convenient for the control module 310 and the compressor 200 to control, so that the temperature of the compressor 200 is within a safe range.

[0058] More specifically, combined with Figure 5 The temperature sensing component exposes the temperature sensing surface for contacting the outer surface of the compressor 200 from the second housing 16, and the temperature sensing component is integrated into the assembly, further improving the integration of the terminal assembly. The temperature sensing component 12 also includes a temperature sensing terminal 123, and the temperature sensing terminal 123 is wrapped in the second housing 16, wherein 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 line 11 includes a first power line 111, a second power line 112 and a third power line 113. That is, the power line 11 can be a three-phase power line 11, which can improve the operation stability and thus improve the reliability of the operation of the air conditioning system 1000.
