[0004] However, in actual use, this structure can often only perform simple internal coolant circulation and heat dissipation operations, but the overall heat dissipation effect is poor, which can easily cause the heat inside the cable to be unusable under high-load charging conditions. At the same time, the equipment cannot adapt to the state of the daily external AC charging line of new energy vehicles, and can not efficiently and energy-savingly adjust the heat dissipation capacity, and cannot meet daily use needs. Therefore, it is urgent to design a new energy vehicle external AC charging cable to solve the above problems. Utility Model Content

At the same time, the equipment cannot adaptably and efficiently adjust the heat dissipation capacity according to the daily state of the external AC charging line of the new energy vehicle, and cannot meet the daily use needs.

At this time, the heat-conducting sleeve and the heat-conducting inner pad are adaptively fitted, so that the heat inside the cable tube can be quickly discharged. At the same time, the first connecting ring sleeve, the heat-conducting sleeve and the second connecting ring sleeve can be installed in multiple groups on the cable tube intermittently, so as to ensure the charging and heat dissipation effect of each section of the cable tube, which reflects the practicality of the equipment design.
