For the energy supply of new energy vehicles, it is usually necessary to use new energy vehicle charging plugs to charge the new energy vehicles to ensure the normal storage and supply of electricity.

[0003] When charging, the current charging plug needs to be inserted into the charging socket of the electric vehicle for charging. However, due to the heavy weight of the charging cable itself, it is very easy to cause the charging plug to deflect downward, which can easily lead to poor contact between the plug and the socket and cause damage to the new energy vehicle. For this reason, we propose a high-safety charging plug for new energy vehicles. Utility Model Content
