This application solves the problem that the charging ports of most existing new energy vehicles are similar to those of fuel vehicles, and are all covered and hidden by a cover. However, the covers of new energy vehicles are open when charging, and the charging time is relatively long, which makes the charging ports of new energy vehicles exposed to the outside for a long time, and external rain or dust can easily adhere to the vicinity of the charging port, which may have a certain impact on the charging port after a long time. However, the charging interface in this application does not have a structure for auxiliary fixation of the charging port and the car charging seat. In practice, the connecting parts between the fast charging interface and the car charging seat may become loose or even detached when subjected to certain external forces. This problem of loose connection may cause the charging process to be interrupted, and in severe cases may even cause electrical failures or safety accidents. Utility Model Content

[0016] 1. In the utility model, by means of the provided snap-fit ​​structure, when the fast charging interface is connected to the vehicle charging seat to charge the new energy electric vehicle, the charging port is inserted into the vehicle charging seat, and the position of the charging port is limited by the limit block at the lower end of the charging port to prevent problems such as reverse insertion or misalignment.
