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.

    本发明公开了一种电动汽车用防水充电插头,涉及电动汽车充电技术领域。本发明包括插头本体和防水套,插头本体包括圆柱形连接部及分别一体成型设置在圆柱形连接部两端的插合部和手持部,防水套滑动套接在圆柱形连接部的外侧;圆柱形连接部靠近插合部一侧的外壁上固设有限位环,同时圆柱形连接部的另一侧外壁上固设有轴向截面呈L形的锁合套;防水套的内部上沿周向均布设置有多个凸头导向杆,同时限位环的外边沿上设置有多个用于凸头导向杆间隙配合的凸头导槽。本发明在给电动汽车进行充电时,在雨雪天起到防水的同时还可以兼顾内部的散热,具有很好的保护作用,同时可以避免充电完成后因为忘记拔插头而导致插头和汽车的损坏,整体实用性好。
