Vehicle-mounted waterproof charging connection device

Abstract

This invention relates to a vehicle-mounted waterproof charging connection device, comprising: a housing, a power supply unit, a cover, and two caps. The power supply unit and the two caps are located inside the housing, while the cover is connected to the housing and has two limiting parts inside. Each cap has elastic deformation characteristics and has a connecting part and a covering part. The connecting part can cooperate with the limiting part to operate. When the two caps are not subjected to external force, the covering parts of the two caps together cover the opening of the cover, isolating the cover space from the outside world to achieve a waterproof effect. When the two caps are squeezed by external force, the caps undergo elastic deformation to allow the covering parts to separate from the opening of the cover. The connecting part and the covering part can deform to different degrees under the action of the limiting parts. Thus, when the vehicle-mounted waterproof charging connection device is not plugged in, the two caps can automatically cover the opening of the cover by utilizing their elasticity, thereby improving the waterproof effect of the vehicle-mounted waterproof charging connection device.
