The invention discloses a non-insulated isolated cooling high-power liquid cooling charging connector, which comprises a multi-strand wire DC + and a multi-strand wire DC-, the head of the multi-strand wire DC + is welded with a DC + core member, and the head of the multi-strand wire DC-is welded with a DC-core member; the DC + core part and the DC-core part are inserted into the front insulating plate, the front insulating plate is inserted into a vehicle charging port to be connected with a vehicle-mounted battery, the tail parts of the multi-strand wire DC + and the multi-strand wire DC-jointly form a stranded cable, and the stranded cable is connected with the positive electrode and the negative electrode of a charging pile to form a charging loop; and an insulating heat-conducting layer is arranged in the cooling shell and on the inner wall of the DC core piece so as to form two cooling liquid flowing loops. According to the scheme, heat generated in the charging process is taken away through the two cooling liquid flowing loops which are independently arranged and do not interfere with each other, so that charging is stably and efficiently completed, power output of 800-1000 KW can be achieved, and the cooling liquid flowing loops for rapid charging of the electric vehicle are achieved.
