A new energy vehicle charging cable resistant to bending and crushing

Abstract

The invention discloses a bending-resistant and rolling-resistant new energy vehicle charging cable, which relates to the technical field of cables, and includes a cable body, the cable body includes a conductor, the outer surface of the conductor is covered with an insulating layer, and the inside of the cable body is A communication line is installed on the side close to the conductor, and a PP net is filled between the conductor and the communication line, and the outer side of the conductor, the communication line and the PP net is wrapped with an isolation layer, and the outer side of the isolation layer is covered with a jacket The preparation method is as follows: wrap the insulation layer on the outside of the cable body, wrap the isolation layer on the outside of the conductor, communication line and PP net, wrap the outside of the isolation layer to obtain the cable, and use the traction recovery equipment to recycle the cable to obtain the product. In the present invention, the outer sheath of the cable adopts a special composite cross-linked TPE mixture, which can satisfy the aging resistance, flame retardancy, weather resistance and oil resistance of the outer shell at the same time, so as to extend the service life of the outer shell and enhance the protection ability of the inner structure of the cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a bending-resistant and rolling-resistant new energy vehicle charging cable. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. When charging new energy, in order to To improve efficiency, a cable is often used as a charging medium. A cable is an electrical energy or signal transmission device, usually composed of several wires or groups of wires. [0003] A Chinese patent discloses a charging cable for electric vehicles and its preparation method (publication number; CN201510615225.2). Sheath; the inner core of the cable includes a power supply line, a grounding line, a signal transmission control line and an auxiliary power line; they respectivel...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned existing cables, they will be affected by various unfavorable environments including sunlight, weathering, humidity, sea water, oil pollution, acid rain, freezing, etc., and at the same time, they are often bent and dragged during use, and friction will inevitably occur , scratching, crushing and other mechanical damages, which have higher requirements on the softness, flexibility and mechanical properties of the cable. The purpose of this invention is to provide a new energy source that is resistant to bending and crushing car charging cable
