A liquid-cooled high-voltage connector provided by the present invention comprises a plug shell, and a liquid-cooled pipe and a liquid-cooled cable which penetrate out of the plug shell, the liquid-cooled pipe extends along the length direction of the liquid-cooled cable, the liquid-cooled cable is internally provided with a cooling liquid flow channel, the plug shell is internally provided with a liquid-cooled box body, the liquid-cooled box body is internally provided with a liquid-cooled pipe, and the liquid-cooled pipe extends along the length direction of the liquid-cooled cable. The liquid cooling box body is respectively connected with the liquid cooling pipe and the cooling liquid flow channel, and the liquid cooling pipe, the liquid cooling box body and the cooling liquid flow channel form a loop for circulating flow of cooling liquid. The liquid cooling box body is made of the hollow high-thermal-conductivity insulating material, heat generated by the welding surface and the cable conductor is taken away through the tightly-contacted heat conduction surface, and then the heat is taken away by the cooling liquid in the liquid cooling box body through heat exchange, so that temperature rise caused by high-power electric connection charging is reduced, and the cooling efficiency is effectively improved.
