Description

Technical Field

[0001] The utility model relates to the technical field of charging pile cables, in particular to a high-strength charging pile cable. Background Art

[0002] A charging pile is a device that replenishes electricity for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in public buildings and residential parking lots. It can charge various types of electric vehicles by adjusting the voltage and current. The charging pile cable is the cable used in the charging pile.

[0003] Most charging piles are installed outdoors, and most of the cables used in the charging piles are directly exposed to the outside and are easily damaged by the outside. In order to avoid short circuits or damage to the wire core, the cables used in the charging piles need to have higher strength.

[0004] According to the search, the Chinese patent document, announcement number: CN218513202U, discloses a high-strength, low-temperature resistant, flame-retardant cable for charging piles, which uses soft copper wires drawn from multiple oxygen-free copper rods to twist the power core conductor and the control core conductor, which has high conductivity to ensure the large current carrying capacity of the cable during use, and adds high-strength tensile fiber rope 2 when twisting the control core conductor, so that the cable is not easy to break when it is bent and dragged, effectively extending the life of the cable. However, this cable only has a tensile structure and poor wear resistance. When the cable is dragged, it is easy to wear and tear, and when it is punctured, it is easy to directly damage the internal core. Utility Model Content
