A detachable and replaceable structure of a power terminal of a direct current charging gun relates to a DC + power terminal and a DC-power terminal which are installed in the direct current charging gun, the DC + power terminal and the DC-power terminal are respectively composed of a plug part and a tail seat part, and the tail seat part is connected with the plug part through a thread structure. And a conical contact surface for electric conduction is arranged between the tail seat part and the plug part. During installation, the tailstock part is fixed in the charging gun, and the plug part is in threaded connection with the head end of the tailstock part through threads. When the charging gun is replaced, the ablation phenomenon occurs on the plug part, only the ablated plug part needs to be screwed off, then a new plug part is screwed on, and the charging gun does not need to be disassembled in the whole process. The conical contact surface is arranged between the tail seat part and the plug part, so that the conductive area between the tail seat part and the plug part can be greatly increased, the contact resistance is reduced, and the conductivity of the whole power terminal is improved. In addition, the power terminal is also provided with heat dissipation holes on the plug part, and the heat dissipation holes are beneficial for dissipating heat generated by the plug part, thereby reducing the temperature of the power terminal.

    一种直流充电枪功率端子的可拆换结构,涉及安装在直流充电枪内的DC+和DC‑功率端子,DC+和DC‑功率端子均由插头部和尾座部构成,尾座部与插头部通过螺纹结构连接;在尾座部与插头部之间设置有用于导电的锥形接触面。安装时,将尾座部固定在充电枪内,插头部通过螺纹螺接在尾座部的头端。烧蚀现象发生在插头部上,更换时,只需要将烧蚀的插头部拧下来,然后再拧上新的插头部既可,全程不需要对充电枪进行拆解。在尾座部与插头部之间设置锥形接触面,可大幅增加尾座部与插头部之间的导电面积,降低接触电阻,增加整个功率端子的导电性。此外,本功率端子还在插头部上设置有散热孔,散热孔有利于将插头部产生的热量散发出去,降低功率端子的温度。
