[0002] An electric vehicle charging station is a device used to charge electric vehicles. It usually includes a housing, a cable and a charging gun. The cable is connected to the control system and the charging gun inside the housing. When in use, one end of the charging gun is inserted into the charging port of the electric vehicle to charge the electric vehicle.

[0003] However, in order to better charge electric vehicles, the length of cables and charging guns are usually designed to be relatively long, so that the charging guns can be plugged into charging ports at different locations on different electric vehicles, thereby facilitating the charging of electric vehicles. When using an electric vehicle charging station to charge an electric vehicle, the cable needs to be pulled by the charging gun, which is prone to friction with the ground, causing damage to the cable and reducing its lifespan. In addition, the charging gun and cable are exposed to the outside world for a long time, which will accelerate the aging of the cable.
