The invention discloses a charging port of an electric vehicle, and solves the problems of positioning failure and easy damage of parts caused by a fixing mode of hard positioning of a power supply terminal. A support is installed in the shell, an insertion hole for the power supply terminal to be inserted and assembled is formed in the support, a plurality of elastic clamping jaws made of elastic materials are arranged on the insertion hole and evenly arranged in the circumferential direction of the insertion hole, a clamping groove is formed in the power supply terminal, and the elastic clamping jaws are clamped in the clamping groove to limit the power supply terminal. The power supply terminal is fixed through the elastic positioning effect of the elastic clamping jaw, so that the power supply terminal can be elastically fixed on the support, the power supply terminal can be allowed to shake in a small range and a small amplitude in the plugging process, and the elastic clamping jaw can absorb extrusion force caused by shaking of the power supply terminal through elastic deformation. Rigid extrusion of the power supply terminal to the inner wall of the jack is buffered, plugging operation of the charging port is better met, mechanical rigidity is prevented from damaging the power supply terminal and the support, and long-term effective positioning is achieved.
本发明公开了一种电动汽车充电口,解决电源端子硬性定位的固定方式造成定位失效、零件易损的问题。壳体内安装有支架,支架内开设有供电源端子插入装配的插孔,插孔上设置有多个由具有弹性的材料制成的弹性卡爪,多个弹性卡爪沿插孔的周向方向均匀布置,电源端子上开设有卡槽,弹性卡爪卡接于卡槽以限位电源端子。通过弹性卡爪的弹性定位作用固定电源端子,使电源端子可以弹性固定于支架上,允许电源端子在插拔过程中可以进行小范围、小幅度的晃动,弹性卡爪可以通过弹性变形吸收电源端子晃动造成的挤压力,缓冲电源端子对插孔内壁的刚性挤压,更符合充电口的插拔使用操作,避免机械刚性损坏电源端子以及支架,实现长期有效的定位。
