The invention discloses a charging plug, a charging gun and a connector assembly, and relates to the technical field of ground maintenance. The fluid channel defined by the charging plug is used for being connected with a cooling source, and the fluid flowing cavity is communicated with the fluid channel and the fluid interface, so that the charging plug can be conveniently and quickly communicated with a cooling loop of external equipment such as an electric vehicle through the fluid interface on the charging plug, and the thermal management capability is improved. In addition, the charging plug can switch the liquid inlet and outlet direction through the first fluid flowing cavity and the second fluid flowing cavity, and therefore the internal temperature difference of a battery system of corresponding external equipment can be reduced through timing switching. Or, the heat exchange fluid in the loop connecting cavity can independently conduct heat management through the cooling loop of the external equipment, the accuracy of heat management on the external equipment is improved, the temperature uniformity of all positions of the external equipment is improved, and the reliability of the external equipment is improved. The heat exchange fluid in the charging cooling cavity can independently carry out heat dissipation on the to-be-cooled charging terminal or the charging wire harness.
本发明公开了一种充电插头、充电枪以及接头组件,涉及地面维护技术领域。充电插头所限定出的流体通道用于连接冷却源,流体流经腔分别连通流体通道和流体接口,从而能够通过充电插头上的流体接口而方便快捷地与电动交通工具等外部设备的冷却回路连通,从而提高了热管理能力。此外,充电插头能够通过第一和第二流体流经腔而切换进出液方向,从而能够通过定时切换而减小对应的外部设备的电池系统的内部温差;或者,回路连接腔中的换热流体能够独立地通过外部设备的冷却回路进行热管理,有利于提高对外部设备进行热管理的准确性,提高了外部设备各个位置的温度均一性,充电冷却腔中的换热流体能够独立地对待冷却充电端子或充电线束进行散热。
