A natural heat dissipation direct current charging cable is characterized in that two ends of the natural heat dissipation direct current charging cable are connected with copper noses or wiring terminals which are respectively used for connecting a charging gun and a charging pile, four circles of wires are coaxially and tightly arranged in an insulating jacket of the charging cable, and the number of the four circles of wires is twelve, twenty-one, fifteen and six in sequence from outside to inside; the wires of the first circle are thick wires with the same wire diameter, and the two wires of the second circle, the third circle and the fourth circle are thin wires with the same wire diameter. According to the charging cable, the wire diameter of the cable is reduced to the maximum extent on the premise of ensuring the charging power, the wire diameter of the cable is enabled to be 21mm, and the bending radius is reduced to 80mm. The charging cable has the advantages of being thin, light and soft, the use experience feeling of a user is greatly improved, and the charging operation becomes easy. Under the same bearing, the charging cable is large in heat dissipation area and low in temperature rise, the anisotropy of the charging cable in the bending direction is eliminated, and the tensile property of the charging cable is improved.

    一种自然散热直流充电线缆,其两端连接有铜鼻子或接线端子,分别用来连接充电枪和充电桩,在充电线缆的绝缘外被内同轴紧密排列有四圈导线,四圈导线的根数从外向内依次为十二根、二十一根、十五根、六根;第一圈的导线为线径相同的粗导线,第二圈、第三圈、以及第四圈中的两根导线为线径相同的细导线。本充电线缆在保证充电功率的前提下最大限度地减少线缆的线径,将使线缆的线径21毫米,弯曲半径缩小至80毫米。本充电线缆具备细、轻、软的特点,大幅提高了用户的使用体验感,使充电操作变得轻松。在同样的承载下,本充电线缆的散热面积大、温升低,不仅消除了充电线缆在弯曲方向上的各向异性,而且提高了充电线缆的抗拉性能。
