The lightning-proof new energy charging pile plug structurally comprises a gun body, and two third cavities which are distributed up and down and provided with rightward openings are formed in the right side face of the gun body; the charging device is provided with a limiting mechanism, when a charging gun is inserted into a power supply groove to charge a new energy automobile, a first electromagnet is utilized to attract a first sliding block so that a limiting block can be tightly attached to the inner wall of the power supply groove, and the charging gun is prevented from being maliciously pulled out by other people; a control module controls a third electromagnet to attract a first sliding block, so that a limiting block is separated from the inner wall of a power supply groove, and a charging gun can be pulled out of the power supply groove, a circuit protection mechanism is further arranged, when a power grid of the new energy charging pile is hit by lightning, because the voltage of a circuit is increased, the attraction force of a second electromagnet is increased, and the charging gun can be pulled out of the power supply groove. When the suction force is greater than the threshold value of the second spring, the conductive metal block is separated from the first metal connecting rod and the fourth metal connecting rod, and the whole circuit is powered off, so that the power supply of the new energy automobile is protected.
本发明公开了一种防雷击的新能源充电桩插头,其结构包括枪体,枪体右侧面设有两个位置上下分布并且开口向右的第三空腔;本发明设有限定机构,当充电枪插入电源槽对新能源汽车充电的时候,利用第一电磁铁吸引第一滑块使得限定块对电源槽内壁紧贴,防止充电枪被别人恶意拔出,当需要将充电枪拔出的时候,通过控制模块控制使得第三电磁铁吸引第一滑块,使得限定块与电源槽内壁脱离,充电枪就能够拔出电源槽,还设有电路保护机构,当新能源充电桩的电网被闪电击中的时候,由于电路的电压升高,使得第二电磁铁的吸力增大,当吸力大于第二弹簧的阈值的时候,使得导电金属块与第一金属连杆、第四金属连杆脱离,整的电路断电,以此保护新能源汽车的电源。
