Description

Technical Field

[0001] The utility model relates to the technical field of liquid-cooled charging guns, in particular to a liquid-cooled charging gun with fast terminal replacement. Background Art

[0002] New energy electric vehicle charging guns can be divided into DC charging guns, AC charging guns, and portable charging guns. Different charging guns are required for different scenarios. If it is for home use, it is recommended to use the ProGu portable charging gun, which can be directly plugged into a household electrical plug for charging. It can be stored in the trunk when not in use, and can be taken out for charging when needed. The charging process is very simple and convenient, but the charging speed is longer than that of a DC charging gun. In order to meet the charging needs of different models of vehicles, a detachable terminal can be added to the gun head of the charging gun to enable the charging gun to be plugged into the charging port of different models; after patent search, it was found that the publication number: CN106887751A discloses a charging gun, which achieves waterproof performance by buckling the waterproof and breathable component in the mounting hole, and provides a heat dissipation channel in the accommodating cavity to reduce the temperature in the accommodating cavity.

[0003] The gun head and the terminal of the existing charging gun are connected by plugging. The gun head and the terminal fit tightly and the terminal is fixed by friction. In order to ensure the stability of the connection between the gun head and the terminal, the gun head and the terminal fit relatively tightly, which makes it difficult to plug and unplug the gun head and the terminal, and the terminal cannot be quickly replaced. To solve the above problem, this application proposes a liquid-cooled charging gun with quick terminal replacement. Utility Model Content
