The invention discloses an anti-electric shock new energy automobile charging interface device which comprises a charging gun and a charging interface installed on an automobile. The outer end portion of the charging interface is provided with an insertion opening allowing the front end of the charging gun to be inserted, and a conductive base is embedded in the front end of the charging gun. Conductive pins used for being inserted into one conductive base are fixed in the charging interface, the conductive base is electrically connected with the charging pile, a groove is formed in the front end of the charging gun, a proximity switch is embedded in the bottom of the groove, a boss used for being inserted into the groove and close to the proximity switch is arranged at the inner bottom of the socket, and the proximity switch is electrically connected with the charging pile. Through the arrangement of the proximity switch, when the charging gun is pulled out from the charging interface, the proximity switch cannot detect the existence of the boss, so that the proximity switch can send a signal to the charging pile, and the charging pile can cut off the power supply of the conductive base, thereby avoiding the phenomenon that the conductive base is still electrified, namely avoiding an electric shock accident.
本发明揭示一种防触电新能源汽车充电接口装置,包括充电枪和安装在汽车上的充电接口,充电接口的外端部上设置有可供充电枪的前端插入的插口,充电枪的前端嵌装有导电座,充电接口中固定有分别用于插入到其中一个导电座中的导电针,导电座与充电桩电连接,充电枪的前端设置有凹槽,凹槽的底部嵌装有接近开关,插口的内底部上设置有用于插入到凹槽中并靠近接近开关的凸台,接近开关与充电桩电连接;本发明通过接近开关的设置,当充电枪从充电接口上拔下来后,接近开关会检测不到凸台的存在,这样一来,接近开关能够发送信号给充电桩,充电桩即可切断导电座的电源,从而能够避免导电座仍然带电的现象,即能够避免引发触电事故。
