[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] In the current manufacturing of charging piles, the connection method with the power cord is mostly to fix the power cord directly to the circuit board by pressing with screws. However, when fixing with screws, the contact area between the screws and the power cord is small, the screws are not pressed in place, and the power cord cannot be completely pressed on the circuit board. The power cord is prone to loosening, posing a safety hazard. Utility Model Content

The power cord is protected by the protective component, which can increase the service life of the power cord and help improve the safety of the wiring device of the charging pile during use.

[0008] In a specific feasible implementation scheme, the locking mechanism includes a conductive column, which is mounted on the circuit board and arranged in the protective component, and a first groove and a threaded hole are respectively provided on the conductive column, and the threaded hole is connected to the first groove; a first screw is threadedly connected to the conductive column, a first nut is provided at one end of the first screw away from the shell, a support plate is installed on the first screw, a first connecting plate is installed on the first screw, a second connecting plate is installed on the first connecting plate, a pressure plate is installed on the second connecting plate, and the pressure plate is slidably connected to the conductive column.

[0009] By adopting the above technical solution, the power cord is inserted into the conductive column, and the first screw is driven to rotate by twisting the first nut. The first screw moves downward to drive the pressure plate to move downward to press the power cord to achieve connection with the circuit board. The pressure plate increases the contact area with the power cord, making the power cord more firmly fixed.

The operation is simple and the firmness of the power cord on the shell is enhanced.

[0018] In a specific implementation manner, a first rubber pad is provided on the first holding sheet.
