Problems solved by technology
The problem that comes with it is: due to the excessive current, the terminal at the charging socket heats up seriously, resulting in burning of the charging terminal or charging failure, so that the whole vehicle cannot be charged normally, and the charging safety cannot be effectively guaranteed
[0004] In addition, although some manufacturers are currently actively adopting some methods to reduce the temperature at the terminal, for example, arranging cooling devices at the charging harness, but the cooling effect is not ideal, and the arrangement is more complicated

The invention discloses a first and a second charging connector, a charging gun, a vehicle and a charging system. The first charging connector includes: a first casing; a first cooling pipeline, and the first cooling pipeline is provided with In the first casing; a moving sleeve, the moving sleeve is sleeved on the first cooling pipeline and can move axially relative to the first cooling pipeline. Thus, the first cooling pipeline of the first charging connector can be docked with the second cooling pipeline between the second charging connector under the action of the moving sleeve, so that the cooling liquid can flow in the first cooling pipeline and the second cooling pipeline, thereby effectively reducing the working temperature of the first terminal and the second terminal, and avoiding the problem of excessive temperature of the first terminal and the second terminal.
Description
technical field [0001] The present invention relates to the technical field of vehicle charging, in particular to a first charging connector, a second charging connector, a charging gun including the first charging connector or the second charging connector and a vehicle, and a charging gun including the first charging connector and the second charging connector. Charging system for the second charging connection. Background technique [0002] At present, due to energy and environmental issues, the explosive growth of new energy vehicles has been promoted, and the number of new energy vehicles has also continued to rise. Compared with traditional fuel vehicles, new energy vehicles have great advantages in energy saving and environmental protection, but the long charging time of electric vehicles has been criticized for a long time. [0003] At this stage, the method of shortening the charging time by increasing the charging power is generally adopted. The problem that come...
