AI Technical Summary
Existing new energy vehicle chargers lack waterproof structures, making them prone to water ingress in humid environments, which can lead to leakage and electric shock accidents. Furthermore, moisture intrusion can accelerate the oxidation of metal contacts, resulting in poor contact and reduced charging efficiency.
A charger with a multi-layer waterproof structure was designed, including a protruding waterproof structure and cover at the charging port, a three-layer gradient waterproof rubber ring at the front end of the charging gun, a protective sleeve at the connection between the charging gun and the power cord, and a detachable charging box to prevent moisture from entering.
It effectively prevents moisture from entering the charger, preventing short circuits and leakage accidents, ensuring charging efficiency and safety, and protecting the internal circuitry from moisture.
