The invention discloses a waterproof charging plug for an electric vehicle, and relates to the technical field of electric vehicle charging. The plug comprises a plug body and a waterproof sleeve, the plug body comprises a cylindrical connecting part and an inserting part and a handheld part which are integrally formed and arranged at the two ends of the cylindrical connecting part respectively, and the waterproof sleeve is slidably connected to the outer side of the cylindrical connecting part in a sleeving mode; a limiting ring is fixedly arranged on the outer wall of the side, close to the inserting part, of the cylindrical connecting part, and meanwhile a locking sleeve with the L-shaped axial section is fixedly arranged on the outer wall of the other side of the cylindrical connecting part. A plurality of raised head guide rods are evenly distributed in the waterproof sleeve in the circumferential direction, and meanwhile a plurality of raised head guide grooves used for being in clearance fit with the raised head guide rods are formed in the outer edge of the limiting ring. When an electric automobile is charged, the waterproof function can be achieved in rainy and snowy days, meanwhile, internal heat dissipation can be taken into consideration, the good protection effect is achieved, meanwhile, the situation that the plug and the automobile are damaged due to the fact that the plug is forgotten to be pulled out after charging is completed can be avoided, and the overall practicability is good.
