[0026] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0027] like Figure 1-Figure 2 As shown, this article provides a terminal assembly of a preferred embodiment, comprising a terminal plug-in portion 1, a vent connection portion 2 and a terminal wiring portion 3 connected in sequence, the outer wall of the vent connection portion 2 is opened with at least one air inlet channel 21 extending outward, and the air inlet channel 21 is connected to a temperature regulating device 5,

[0028] The terminal plug-in portion 1 has a plug-in cavity, and the bottom wall of the plug-in cavity is provided with at least one air outlet 11 communicating with the air inlet channel 21.

[0029] The temperature regulating device 5 is configured to regulate the temperature of the air in the air inlet passage 21 so that the air flows through the air outlet 11 to the plug-in cavity to regulate the temperature of the plug-in cavity.

[0030] The terminals in the existing charging dock will accumulate dust, sand, impurities, and plating chips during the plugging and unplugging process of the gun tip and the terminal. This will reduce the plugging and unplugging force, increase the resistance, and cause the temperature of the plug cavity to rise too high. In addition, in extreme weather, the temperature of the terminal plug cavity will drop when water and snow freeze.

[0031] According to a terminal assembly provided in this article, it includes a terminal plug-in part 1, a ventilation connection part 2 and a terminal wiring part 3 connected in sequence, and a temperature control device 5 is connected to the ventilation connection part 2. The terminal plug-in part 1 has a plug-in cavity, and the bottom wall of the plug-in cavity is provided with an air outlet 11 connected to the air inlet channel 21. The temperature control device 5 adjusts the air temperature of the air inlet channel 21, so that the air flows through the air outlet 11 to the plug-in cavity to adjust the temperature of the plug-in cavity, thereby ensuring the safety of electricity use of the terminal during charging. Compared with ordinary charging seat terminals, this terminal assembly has a rich structure, which solves the problem of excessive temperature rise in the plug-in cavity caused by accumulation of dust, sand, impurities, and plating chips when the charging gun is inserted, and the plug-in cavity freezing in extremely bad weather.

[0032] The terminal plug-in part 1 of the present design is detachably connected to one end of the ventilation connection part 2 by means of a screw connection, a snap connection or an interference connection. The terminal wiring part 3 is also detachably connected to one end of the ventilation connection part 2 by means of a screw connection, a snap connection or an interference connection. The terminal plug-in part 1, the ventilation connection part 2 and the terminal wiring part 3 can all be removed for cleaning, maintenance and replacement.

[0033] In some embodiments, the temperature control device 5 includes a refrigeration device and / or a heating device, and a ventilation device 51 connected to the refrigeration device and / or the heating device.

[0034] The temperature control device 5 may include only a refrigeration device or a heating device, or may include both a refrigeration device and a heating device. The refrigeration device and / or the heating device is connected to a ventilation device 51, and the ventilation device 51 may be a fan or other ventilation device 51 with the function of regulating the air temperature.

[0035] Heating principle: There is a heating element inside, which is usually a heating wire made of metal wire or graphite material. When the power is turned on, the current passes through the heating wire, and the electrical energy is converted into thermal energy, which makes the heating wire heat up, driving the air in the fan to heat up. The fan is then driven by the motor, so that the fan blades generate airflow, thereby blowing the generated hot air into the plug-in cavity to increase the temperature of the plug-in cavity; Refrigeration principle: The refrigerant is compressed into a high-temperature and high-pressure gas by the compressor, and then dissipated through the condenser and cooled into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant is then decompressed and liquefied through the expansion valve to become a low-temperature and low-pressure refrigerant. The low-temperature and low-pressure refrigerant enters the evaporator and contacts the surrounding air for heat exchange. In this process, the refrigerant absorbs the heat of the surrounding air, and the air temperature drops. Then, the fan blades driven by the motor blow the cooled air into the plug-in cavity to reduce the temperature of the plug-in cavity; or the temperature is adjusted by a semiconductor refrigeration sheet, one end of the semiconductor is heated and the other end is cooled. The heated end is connected to the heating device, and the cold end is connected to the refrigeration device.

[0036] In some embodiments, it also includes a temperature sensor arranged on the terminal plug-in part 1, and a control module is arranged in the temperature control device 5. The temperature sensor is electrically connected to the control module. The temperature sensor is used to detect the real-time temperature of the terminal plug-in part 1 and transmit the real-time temperature signal to the control module. The control module is configured to control the temperature control device 5 to perform cooling or heating according to the real-time temperature signal.

[0037] In some embodiments, the control module is configured to: when the real-time temperature detected by the temperature sensor is lower than the preset temperature, control the temperature control device 5 to perform heating; when the real-time temperature detected by the temperature sensor is higher than the preset temperature, control the temperature control device 5 to perform cooling.

[0038] In extreme weather, when water and snow freeze, the temperature of the plug cavity may drop. When the real-time temperature detected by the temperature sensor is lower than the preset temperature, the temperature regulating device 5 is controlled to perform heating to increase the temperature of the plug cavity so that the ice melts and the normal use of the terminal assembly is ensured.

[0039] As dust, sand, impurities, plating chips, etc. accumulate during the process of plugging and unplugging the gun tip and the terminal, the plugging and unplugging force becomes smaller, the resistance becomes larger, and the terminal temperature rises too high. When the real-time temperature detected by the temperature sensor is higher than the preset temperature, the temperature control device 5 is controlled to perform cooling to reduce the temperature of the plug-in cavity and ensure the electrical safety of the terminal assembly during charging.

[0040] In some embodiments, there are two air inlet passages 21 and two temperature regulating devices 5 , and each of the air inlet passages 21 is connected to one of the temperature regulating devices 5 .

The temperature sensor is electrically connected to the control module. The temperature sensor is arranged close to the terminal plug-in part 1 and detects the real-time temperature of the terminal plug-in part 1, and transmits the real-time temperature signal to the control module. The control module is electrically connected to the temperature control device 5, and the control module is configured to control at least one of the temperature control devices 5 to perform cooling or heating according to the real-time temperature signal.

[0048] In some embodiments, the control module is configured to: when the real-time temperature detected by the temperature sensor is lower than the preset temperature, control at least one of the temperature control devices 5 to perform heating; when the real-time temperature detected by the temperature sensor is higher than the preset temperature, control at least one of the temperature control devices 5 to perform cooling.

[0052] The heating device heats the air, and the heating device is connected to the ventilation device 51. The heated air enters the ventilation device 51. The ventilation device 51 is driven by an electric motor, and the blades generate airflow, so that the generated hot air enters the air intake channel 21 through the air intake pipe 4, thereby increasing the air temperature in the air intake channel 21.

[0053] The refrigeration device cools the air, and the refrigeration device is connected to the ventilation device 51. The refrigerated air enters the ventilation device 51. The ventilation device 51 is driven by an electric motor, and the blades generate airflow, so that the generated cold air enters the air intake channel 21 through the air intake pipe 4, thereby reducing the air temperature in the air intake channel 21.
