Description

Technical Field

[0001] The utility model relates to the technical field of charging pile cables, in particular to a high-performance and durable 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] The charging pile cable will generate a lot of heat when in use, but the traditional charging pile cable does not have a cooling structure and can only be cooled by an external cooling fan. After using it for a period of time, the heat may cause damage to the cable and its durability will not be improved.

[0004] According to the search, Chinese patent literature, announcement number: CN210039687U, discloses a high-performance new energy vehicle charging pile cable, which solves the problem of short service life of existing high-performance new energy vehicle charging pile cables by setting a protective frame, a rubber plate, a first filling block, a protective layer, a polytetrafluoroethylene layer, a fluorosilicone ethylene layer, a polyvinyl chloride layer, a rock wool layer, a nano coating and a chlorosulfonated polyethylene rubber layer. The high-performance new energy vehicle charging pile cable has the advantage of long service life. The polytetrafluoroethylene layer can improve corrosion resistance, the fluorosilicone ethylene layer can increase its aging resistance, the polyvinyl chloride layer can increase heat resistance, the rock wool layer can increase fire resistance, the nano coating can increase toughness, and the chlorosulfonated polyethylene rubber layer can increase acid and alkali resistance, which is beneficial to people's use. By setting wear-resistant particles, the wear resistance can be increased and a good protective effect can be played. By setting an anti-static layer, static electricity can be effectively prevented and practicality can be improved. By setting a rubber rod, a good supporting effect can be effectively played and stability can be increased. By setting a second filling block, a good protective effect can be played and toughness can be increased. However, the cable does not have a heat-conducting structure, and the heat generated during use cannot be transferred out quickly. The damage caused by the continuous rise in heat will reduce the service life of the cable. Utility Model Content
