The invention relates to a mistaken-unplugging-preventing and unplugging-forgetting-preventing charging socket for a new energy automobile and relates to the technical field of new energy. The charging socket comprises a housing; a conductive column is fixedly connected to the middle of the housing; a fan-shaped block is rotatably connected to the inner top wall of the housing; a dielectric plateis fixedly connected to the middle of the fan-shaped block; a fan-shaped groove is formed in the inner top wall of the housing; and a first spring fixedly connected with the fan-shaped block is fixedly connected to the inner top wall of the housing. According to the charging socket provided by the invention, the dielectric plate matches a positive plate and a negative plate for use; when the gun body is inserted into the housing, the fan-shaped block is extruded into the housing; at the moment, the dielectric plate reduces the relative area of the positive plate and the negative plate to the minimum;, the voltage of the negative plate is smaller than the minimum access voltage of the resistor, so that the circuit is disconnected; a resistor is connected with the power supply circuit of thenew energy automobile, and the power supply of the new energy automobile is disconnected, so that a driver is reminded that the charging gun is not pulled out, and the charging pile is effectively prevented from being damaged.
一种新能源汽车用防误拔且防忘拔的充电插口,涉及新能源技术领域,包括壳体,所述壳体的中部固定连接有导电柱,壳体的内顶壁转动连接有扇形块,扇形块的中部固定连接有电介质板,壳体的内顶壁开设有扇形槽,壳体的内顶壁固定连接有与扇形块固定连接的弹簧一。该新能源汽车用防误拔且防忘拔的充电插口,通过电介质板与正极板和负极板的配合使用,当枪体插入壳体内时,扇形块被挤入壳体内,这时电介质板将正极板和负极板的相对面积减小至最小,这时通过负极板的电压小于电阻的最小通路电压,导致电路断开,因为电阻与新能源汽车的电源电路连通,导致新能源汽车电源断开,从而达到了提醒驾驶人员充电枪没拔,有效防止充电桩被破坏。
