[0002] The comprehensive performance of existing products is poor, and the service life is short. Since the working environment of electric vehicle cable is relatively harsh, there may be oil stains, acid and alkali, and water and other substances, and the cable needs to be frequently dragged and bent during use. Therefore, the cable requires high resistance to oil stains, acid and alkali, water, bending, tension, flexibility, tearing and wear.

[0003] According to the search, the application number of patent announcement CN207302682U discloses a new energy vehicle fast charging high-voltage cable, which comprises a plurality of core wires and an insulation layer wrapping the core wires. The plurality of core wires are twisted into one body. The charging pile cable further comprises a filler between the core wires and a sheath layer wrapping all the core wires. The sheath layer comprises a water-blocking tape and a high-flexibility insulation layer from the inside to the outside. The core wires include power transmission lines, signal transmission lines and control core wires, which can improve the insulation and heat dissipation of the cable.

[0004] However, due to the setting of the insulation layer, the single-layer toughness layer results in low toughness of the cable, which can easily cause the copper wire to break after long-term use, and the service life is low. At the same time, the cable core is easily disturbed by internal and external electromagnetic signals, and the electromagnetic shielding performance is poor, which affects the use effect of the cable.

[0005] Therefore, we propose a high-flexibility automobile charging cable. Utility model content
