[0037] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0039] The technical solutions of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0040] like Figures 1 to 4 As shown, the embodiments of the present invention provide some connectors. The connectors are used in a compressor to achieve the connection between the compressor and the power supply device.

[0041] For refrigerators, air conditioners and other refrigeration equipment with air supply, heat exchange or temperature regulation functions, the compressor is one of the essential components. The function of the compressor is to compress the refrigerant entering it, that is, to convert the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant, and send the refrigerant back to the refrigerant circulation system of the refrigeration equipment.

[0042] During the use of the compressor, there may be a variety of problems or failures such as short circuit, overload and overtemperature. For example, when the compressor is powered on, the current may increase abnormally due to motor short circuit and other reasons. Alternatively, the temperature of the compressor may increase abnormally due to compressor operation failure and high outdoor temperature. The abnormal increase in current or voltage, as well as the abnormal increase in temperature may damage the electronic components of the compressor and may even damage the corresponding refrigeration equipment. Therefore, it is very necessary to set up corresponding protection devices for the compressor.

[0043] In the embodiment of the present invention, the protection device 400 is arranged on the connector. The protection device 400 is used to protect the compressor to prevent the compressor and the refrigeration equipment from being damaged by problems such as excessive current or voltage, or excessive temperature. In addition, the embodiment of the present invention not only realizes effective protection of the compressor, but also makes the protection device 400 easier to install or assemble.

[0044] Embodiment 1:

[0045] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connector. The connector includes: a connecting wire 300 and a protection device 400. The connecting wire 300 is suitable for connecting a power supply device and a compressor to each other so that the power supply device supplies power to the compressor. The protection device 400 is arranged on the connecting wire 300 to control the on and off of the current in the connecting wire 300 to protect at least one of the compressor and the power supply device.

[0046] The function of the connecting line 300 is to connect the power supply device and the compressor to each other. The power supply device is provided with a power supply line, which extends to the compressor and is connected to the connecting line 300. The power supply device refers to a device that can provide electric energy to the compressor. It can be a refrigeration device body used in conjunction with the compressor, or it can be an external power supply that supplies power to the refrigeration device body and the compressor, such as a wall power supply or an external generator. Among them, the power supply line and the connector of the power supply device can be directly connected by wires, or they can be connected to each other by the cooperation of a plug and a socket.

[0047] In this embodiment, the protection device 400 is arranged on the connecting line 300, and its purpose is to facilitate the installation of the protection device 400. Specifically, the overcurrent protection device or the temperature protection device in the related art needs to be installed separately, and it and the connecting piece are two independent parts. The overcurrent protection device or the temperature protection device in the related art needs to be configured with a special circuit and a connection and fixing structure, thereby realizing the electrical connection and physical connection between the overcurrent protection device or the temperature protection device and the compressor. This leads to the complicated installation and assembly process of the protection device in the related art, many parts, and high production and manufacturing costs. In this embodiment, the protection device 400 is directly arranged on the connecting line 300, so there is no need to set a circuit structure and a connection and fixing structure for the protection device 400 separately or additionally. Therefore, this embodiment improves the installation and assembly efficiency of the protection device and the compressor, reduces the number of parts, and reduces the production and manufacturing costs.

[0048] Embodiment 2:

[0049] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connecting piece. In addition to the technical features of the above-mentioned embodiment 1, this embodiment also includes the following technical features.

[0050] The compressor of this embodiment includes: a compressor housing and a compressor body.

Among them, the connecting piece is arranged inside the compressor housing, one end of the connecting line 300 is connected to the power supply device interface, and the other end of the connecting line 300 is connected to the compressor body.

[0051] In this embodiment, the compressor housing has a hollow cylindrical structure, and usually an upper cover and a lower cover are respectively provided at its upper and lower ends. The compressor body is arranged in the compressor housing, and the compressor body at least includes a motor assembly and a compression assembly, and the motor assembly and the compression assembly are connected to each other and placed up and down. The compression assembly includes components such as a main bearing, a cylinder, a secondary bearing, a piston, a vane and a crankshaft. The motor assembly includes a stator and a rotor, and the rotor is rotatably arranged in the stator. The rotor is fixed to the crankshaft to drive the crankshaft of the compression assembly to rotate. When the motor assembly is working, it drives the piston sleeved on the crankshaft to roll along the inner cavity of the compression assembly, thereby compressing the refrigerant entering the compression assembly.

[0052] In this embodiment, the connector is disposed inside the compressor housing, and accordingly, the protective device 400 on the connector is also disposed inside the compressor housing. Optionally, one end of the connecting wire 300 is connected to the terminal on the compressor housing, and the other end is connected to the motor assembly in the compressor body.

[0053] In this embodiment, the connecting piece is arranged inside the compressor housing and between the power supply device interface and the compressor body. Therefore, when abnormalities such as overcurrent or overheating occur, the protection device 400 can promptly cut off the power transmission between the power supply device interface and the compressor body, thereby effectively protecting the compressor body.

[0054] Embodiment 3:

[0055] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connecting piece. In addition to the technical features of the above-mentioned embodiment 1, this embodiment also includes the following technical features.

[0056] The compressor includes: a compressor housing, a compressor body and a frequency conversion controller. The compressor housing is provided with a power supply device interface suitable for connecting the power supply device. The compressor body is arranged inside the compressor housing. The frequency conversion controller is arranged outside the compressor housing and is suitable for controlling the frequency of the compressor body. Among them, the connecting piece is arranged outside the compressor housing, one end of the connecting line 300 is connected to the power supply device interface, and the other end of the connecting line 300 is connected to the frequency conversion controller.

[0057] In this embodiment, the function of the frequency conversion controller is to change the operating frequency of the compressor body to improve the working efficiency of the compressor and achieve the purpose of energy saving and power saving. Among them, those skilled in the art can select the type, specification and model of the frequency conversion controller according to actual conditions.

[0058] In this embodiment, the connecting piece is arranged on the outside of the compressor housing and between the power supply equipment interface and the frequency conversion controller. Therefore, when an abnormality such as overcurrent or overheating occurs, the protection device 400 can promptly cut off the power transmission between the power supply equipment interface and the frequency conversion controller, thereby effectively protecting the frequency conversion controller.

[0059] Embodiment 4:

[0060] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connecting piece. In addition to the technical features of any of the above embodiments, this embodiment also includes the following technical features.

[0061] The number of the connecting wires 300 is at least two, and the protection device 400 is disposed on any connecting wire 300 .

[0062] In order to realize power transmission between the power supply equipment and the compressor, the connector of this embodiment may include multiple connecting lines 300, wherein the protection device 400 of this embodiment may be arranged on any one of the connecting lines 300, and can realize the function of cutting off the circuit or current.

[0063] Embodiment 5:

[0064] like Figures 1 to 4As shown, an embodiment of the present invention provides a connecting piece. In addition to the technical features of any of the above embodiments, this embodiment also includes the following technical features.

[0065] The protection device 400 is connected in series in the connection line 300. The protection device 400 is suitable for detecting at least one of the current and the voltage in the connection line 300, and controlling the on and off of the current in the connection line 300 according to at least one of the current and the voltage.

[0066] Specifically, the protection device 400 of this embodiment can be an overcurrent protection device or an overvoltage protection device, wherein the specific type, specification, model and combination of the overcurrent protection device or the overvoltage protection device can be selected by those skilled in the art according to actual needs.

[0067] The principle of the overcurrent protection device and the overvoltage protection device is to determine whether the compressor is abnormal or faulty by detecting the electrical parameters in the circuit, and to cut off the power supply in time when the abnormality or fault occurs, so as to stop the operation of the power-consuming equipment such as the compressor, so as to achieve the protection purpose. For example, the overcurrent protection device can be provided with a thermistor. When the current flowing through the thermistor is normal, its resistance is relatively small. When the current flowing through the thermistor is abnormal and increases from normal, its resistance increases accordingly to cut off the current and implement protection.

[0068] In this embodiment, the protection device 400 is arranged in the connecting line 300, so it can directly and accurately know the operating status of the compressor by detecting at least one of the current and the voltage, thereby performing power-off protection in time.

[0069] Embodiment 6:

[0070] like Figures 1 to 4 As shown, an embodiment of the present invention provides a connecting piece. In addition to the technical features of any of the above embodiments, this embodiment also includes the following technical features.

[0071] At least a portion of the protection device 400 is close to the compressor housing, so that the protection device 400 detects the temperature of the compressor housing and controls the on and off of the current in the connecting line 300 according to the temperature.

[0072] The protection device 400 of this embodiment is a temperature protection device. The specific type and specification of the temperature protection device can be selected by those skilled in the art according to actual needs. The principle of the temperature protection device is to detect the temperature anomaly of the refrigeration equipment and cut off the power supply in time to stop the operation of the power-consuming equipment such as the compressor, thereby achieving the protection purpose.

[0073] For example, the temperature protection device is equipped with a temperature sensor and a controller that are connected to each other by signal. The temperature sensor can detect the ambient temperature and feed back to the controller. When the temperature is too high, the controller cuts off the power supply to implement protection.

[0074] In this embodiment, at least a portion of the protection device 400 is close to the compressor housing, so the temperature of the surface of the compressor housing can be obtained timely and accurately, thereby timely cutting off power for protection when an abnormality occurs.

[0075] It should be noted that when the connecting piece is disposed inside the compressor housing, the protection device 400 is close to the inner wall of the compressor housing, and when the connecting piece is disposed outside the compressor housing, the protection device 400 is close to the outer wall of the compressor housing.

[0079] The function of the first connector 100 is to realize the connection between the connecting line 300 and the power supply device interface, so its specifications and models are mutually adapted to the specifications and models of the power supply device interface. For example, the power supply device interface of the compressor can be a wiring terminal. Figure 2 As shown, the first connector 100 is provided with a terminal matching portion 120 adapted to the terminal.

[0080] In this embodiment, the protection device 400 is disposed on the first joint 100 , so as to facilitate fixing the protection device 400 through the first joint 100 , and further facilitate installation and assembly of the protection device 400 .

[0081] In addition, since the first connector 100 connects the connecting wire 300 to the power supply device interface, it extends into or is embedded in the power supply device interface, and the power supply device interface is provided on the compressor housing, so the first connector 100 is in contact with or close to the compressor housing. In this embodiment, the protection device 400 is provided on the first connector 100. When the protection device 400 includes a temperature protector, this embodiment can ensure that the protection device 400 is close to the compressor housing to a large extent, so as to obtain accurate temperature detection parameters.

The shape of the groove 110 is adapted to the shape of the protection device 400, and is slightly larger than the protection device 400, so that the protection device 400 can be extended into the groove 110 and the heat dissipation of the groove 110 is facilitated.

[0088] In this embodiment, the setting of the groove 110 can facilitate the installation and fixation of the protection device 400, and the setting of the groove 110 enables the protection device 400 to be closer to the compressor housing. Therefore, when the protection device 400 includes a temperature protector, this embodiment can ensure that the protection device 400 obtains accurate temperature detection parameters.
