Abstract
An electric vehicle charging connector device comprises a plug connector and a receptacle connector docking with the plug connector. The plug connector includes a first insulating body, a first circuit board, a plurality of contact terminals, a first electrode unit and a first jumper unit. The receptacle connector includes a second insulating body, a second circuit board, a plurality of docking terminals, a second electrode unit, a second jumper unit and a waterproof ring. The first jumper unit of the plug connector and the second jumper unit of the receptacle connector are respectively secured on the first electrode unit and the second electrode unit by a riveting way which allows a firm electrode connection and low probability of looseness between the plug connector and the receptacle connector so as to ensure a stability and accuracy of electricity transmission and a battery charge integrity.
