Problems solved by technology
Therefore, a lot of cable core wires are integrated in the charging cable, and the bending ability is poor. Since the charging interface positions of various models are different, the charging cable needs to have better flexibility to facilitate docking with the charging interface.
Therefore, the current method is to make the charging cable very long, or to use a special flexible cable. These two methods greatly increase the cost of the charging cable, which is not conducive to the large-scale promotion of charging equipment.

Embodiment Construction
[0009] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0010] Such as figure 1 The charging cable shown includes a cable core, a wrapping tape 2 wrapped outside the cable core and an outer sheath 1 in turn; the cable core includes a first power line 4, a second power line 5, a third power line 6, and a fourth power line 7. The fifth transmission line 8, the sixth transmission line 9, the ground line 10, the communication line 11, and the insulating filling layer 3 filled between the first to sixth transmission lines, the ground line 10, and the communication line 11.
[0011] The cross section of the cable core is elliptical, and the first power transmission line 4 and the second power transmission line 5 are respectively located at two ends of the major axis of the ellipse in the cross section of the cable core. The section of the third transmission line 6 and the fourth transmission line 7...

The invention provides a charging cable with low cost and better bending property. A cable core comprises first to sixth power transmission lines, a ground wire, a communication line and insulating filling layers, wherein the insulating filling layers are filled among the first to sixth power transmission lines, the ground wire and the communication line; the cross section of the cable core is of an oval shape; the first power transmission line and the second power transmission line are respectively located at the two ends of the long axis of the oval of the cross section of the cable core. The cross section of the charging cable provided by the invention is of an oval shape; compared with the cable with a circular cross section, the charging cable provided by the invention is in a flat form, so that excellent bending property is formed along the direction of the short axis of the oval cross section, the structure of the inner circuit is compact, the layout is reasonable and the whole manufacturing cost is low.
Description
technical field [0001] The invention relates to the field of cables, in particular to a charging cable. Background technique [0002] With the promotion of electric vehicles, the use of charging equipment has also attracted more and more attention from car owners. At present, the charging cable on the electric vehicle charging pile needs to be equipped with three-phase and two-phase power lines and ground wires at the same time, so as to match the charging interface of different models. At the same time, for safety reasons, a communication line needs to be set in the charging cable In order to monitor the situation of the power battery in the car, in addition, there is usually at least one spare power line designed in the charging cable. Therefore, a lot of cable core wires are integrated in the charging cable, and the bending ability is poor. Since the positions of the charging interfaces of various models are different, the charging cable needs to have better flexibility ...
