The invention discloses a conductive charging system for a new energy vehicle. The conductive charging system comprises a power supply network connector, a control and protection device and a vehiclecoupling device, which are electrically connected in sequence. The vehicle coupling device comprises a shell, a control switch and a resistor, wherein the control switch and the resistor are arrangedin the shell, and the resistor is arranged in the control switch and is electrically connected with the control switch. According to the invention, compared with a resistor and a control switch whichare arranged in a split mode in the prior art, the resistor is arranged in the control switch, so the waterproof performance of the connecting position of the resistor and the control switch is greatly improved, the situation that the connecting position is loosened due to external force can be effectively prevented, and the using requirement of a user is met.
