The invention provides an electric vehicle charging gun which comprises a PCB of an annular structure, a plurality of sets of contact assemblies are arranged on the front face of the PCB at intervals, the contact assemblies are a charging communication CAN-H, a charging communication CAN-L, an electric connection confirmation CC1 and a charging connection confirmation CC2 respectively, and each contact assembly comprises a conduction column. And the conduction columns respectively corresponding to the low-voltage auxiliary power supply positive electrode and the low-voltage auxiliary power supply negative electrode are positioned in front of the PCB. And the positive coil is arranged in the annular interior of the PCB. The grounding shaft is vertically arranged in the middle of the positive coil in a penetrating mode, an insulating tube is arranged between the outer wall of the grounding shaft and the inner side of the positive coil, and the grounding shaft is made of iron-containing materials. And the negative coil is arranged on the outer side of the PCB. The socket of the electric vehicle is provided with corresponding contact points corresponding to the conducting column, the positive coil, the grounding shaft and the negative coil, and the contact point matched with the grounding shaft is made of a magnet. The plugging force can be reduced, the abrasion is greatly reduced, and the service life of the charging gun and the electric vehicle socket is effectively prolonged.
本申请提供一种电动车充电枪,包括:PCB板呈环形结构,其正面间隔设有多组触头组件,触头组件分别为充电通信CAN‑H、充电通信CAN‑L、电连接确认CC1、充电连接确认CC2,触头组件均包括导通柱。低压辅助电源正与低压辅助电源负分别对应的传导柱均位于PCB板的前方。正极线圈设于PCB板的环形内部。接地轴垂直穿设于正极线圈的中部,且接地轴外壁与正极线圈的内侧之间具有绝缘管,接地轴为含铁材料制成。负极线圈设于PCB板的外侧。电动车的插座对应导通柱、正极线圈、接地轴及负极线圈均设有相应的接触点,其中与接地轴相匹配的触点采用磁铁制成。可减小插拔力,极大的减少了磨损,有效延长充电枪及电动车插座的使用寿命。
