Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging guns, and in particular to a waterproof structure of a new energy charging gun. Background Art

[0002] New energy usually refers to a type of energy that is cleaner and more renewable than traditional fuel energy. These energies are mainly derived from renewable resources in nature, have relatively little impact on the environment, and produce less pollution during use. With the development of technology, new energy has gradually penetrated into the field of transportation, and the production of electric vehicles and battery vehicles has increased accordingly.

[0003] A new energy charging gun generally refers to a device used to charge electric vehicles or other new energy vehicles. This device is part of the electric vehicle charging infrastructure and is used to transmit electrical energy to the battery of an electric vehicle.

[0004] Then most of the existing new energy charging guns are placed outdoors, so they are easily affected by the outdoor weather. When it rains, the charging gun is easily affected by the rain, causing moisture at the charging gun head, thereby causing damage to the charging gun, causing cost and safety issues.
