[0003] The structure of a DC charging pile usually includes a charger host, a power supply, a charging interface, a display screen, and auxiliary equipment. The charger host is the core part, responsible for power conversion and control. The power supply includes a power switch, a power manager, and a fuse, which are responsible for monitoring the battery status and protecting the charging pile. The charging interface connects the electric vehicle and the DC charging pile and is a key part of power transmission.

[0004] There are usually many wires led out of the DC charging pile, and these wires are uniformly led out through the wire holes. They are easily confused during maintenance, and it takes a lot of time to find the electrical equipment connected to the corresponding wires. In addition, the lead wires are divided into weak wires and strong wires. Weak wires are usually used to transmit signals or data. Strong wires have greater electromagnetic interference and electromagnetic radiation. Strong wires have more electromagnetic noise and stray signals, which will affect the normal signal output of weak wires, reduce the signal quality of weak wires, or cause data transmission loss. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

[0025] Reference example Figures 1 to 3, A DC charging pile, including a pile body 1 and a base 2 provided at the bottom of the pile body 1. The base 2 is provided with a strong wire hole 21 and a weak wire hole 22. A partition 23 is provided between the strong wire hole 21 and the weak wire hole 22. The strong wire hole 21 and the weak wire hole 22 are provided with a wire passing board 3. The wire passing board 3 is provided with a number of equally spaced wire passing holes 31. One end of the wire passing hole 31 is provided with a convex portion 32. The convex portion 32 is evenly distributed around a circle and extends to be provided with a number of equally spaced tightening portions 33. A tightening cap 4 is threadedly connected to the convex portion 32. The tightening cap 4 abuts against the tightening portion 33 for making the tightening portion 33 contract inward in the central direction. By providing the strong wire hole 21 and the weak wire hole 22, the strong and weak wires are separated, which not only facilitates the maintenance to find the electrical equipment connected to the corresponding wire, but also, through the partition 23 and the distance between the strong wire hole 21 and the weak wire hole 22, prevents the strong wire from affecting the normal signal output of the weak wire. By providing a plurality of wire passing holes 31, each wire passing hole 31 can accommodate the wire led out by an electrical equipment, effectively sorting out the wires, greatly reducing the time for finding the electrical equipment connected to the corresponding wire during maintenance;

[0026] It is worth mentioning that the other end of the wire passing hole 31 is provided with a blind hole 311. The blind hole 311 is provided with a wire threading sleeve 34. The entrance of the wire threading sleeve 34 is provided with a tapered portion 341. The material of the wire threading sleeve 34 is selected as rubber. The tapered portion 341 facilitates the wire to smoothly enter the wire threading sleeve 34, and then the wire will fit against the inner wall of the wire threading sleeve 34;

[0027] It is worth mentioning that the wire passing board 3 is provided with an annular sealing groove 35. The wire passing hole 31 is arranged in the sealing groove 35. The sealing groove 35 is used in cooperation with a sealing ring 51;

[0028] It is worth mentioning that it further includes a cover plate 5. The cover plate 5 is fixed on the wire passing board 3 and covers the blind hole 311. The cover plate 5 is provided with a sealing ring 51 corresponding to the sealing groove 35. The cover plate 5 fixes the wire threading sleeve 34. The sealing ring 51 is embedded in the sealing groove 35 to prevent water vapor from entering between the blind hole 311 and the cover plate 5, and prolong the service life of the wire threading sleeve 34;

[0029] It is worth mentioning that the outer wall of the tightening portion 33 is provided with an inclined surface 331. The inclined surface 331 is used in cooperation with a diameter reducing portion 41;

[0030] It is worth mentioning that the tightening cap 4 is provided with a diameter reducing portion 41 and abuts against the inclined surface 331. The tightening cap 4 is provided with knurling 42. The diameter reducing portion 41 is narrow at the top and wide at the bottom. As the tightening cap 4 gradually sinks, the diameter reducing portion 41 moves on the inclined surface 331, squeezing the tightening portion 33 to gradually contract inward. The tightening portion 33 tightly presses against the outer wall of the wire, making the wire connected and fixed to the wire passing hole 31. The knurling 42 increases the friction between the user and the tightening cap 4.

[0031] Through the above design, the product can achieve the advantages of improving the maintenance efficiency and anti-interference.
