Description
technical field [0001] The invention belongs to the technical field of new energy automobile parts, and more specifically relates to a charging device for electric automobiles. Background technique [0002] In the field of new energy vehicles, electric vehicles are an important category. Among the most important components of an electric vehicle, the charging device is one of them. When charging an electric vehicle, it is necessary to insert the charging plug into the charging socket to achieve reliable power supply. However, in the prior art, on the one hand, the charging plug and the charging socket are prone to loosening after frequent plugging and unplugging, resulting in poor connection reliability. On the other hand, there is no rainproof function between the charging plug and the charging socket. When it rains, external rainwater easily enters the charging plug, causing a short circuit and damage to the charging device. Contents of the invention [0003] The tec...
