Description

Resistant new forms of energy electric automobile car interior cable of buckling

Technical Field

The utility model belongs to the wire and cable field specifically says so and relates to a resistant new forms of energy electric automobile car interior cable of buckling.

Background

At present, new energy electric vehicles are developed at a high speed, and with the continuous progress of science and technology, the new energy electric vehicles gradually replace the traditional vehicles, and cables in the new energy electric vehicles are bridges between internal systems of the vehicles. However, due to the limited space environment in the vehicle, the cable in the vehicle is usually bent for many times, and some parts even reach 180 degrees of bending, so that the cable has good bending resistance. Therefore, the electric wire and cable in the electric automobile are required to have bending resistance, and the outer layer of the electric wire is required to have better wear resistance and oil resistance. The conductor is generally formed by only twisting bare copper wires, and when the section of the conductor is small, the bending resistance of the product is poor, and the conductor is easy to break when being bent. And the insulation adopts crosslinked polyethylene and silicon rubber, and because the wear resistance is poor, the product is easy to damage in long-term use, and the service life of the product is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at just providing a resistant cable in new forms of energy electric automobile car of buckling to the resistant relatively poor defect of nature of buckling of above-mentioned current interior wire and cable of electric automobile car, use aramid fiber silk and copper foil silk in the conductor, aramid fiber has good properties such as superhigh strength, high-modulus, light in weight, and intensity is 5 ~ 6 times of steel wire, and the modulus is 2 ~ 3 times of steel wire or glass fiber, and toughness is 2 times of steel wire. The copper foil wire has good elasticity, flexibility and bending strength, and the bending resistance and the like which are far higher than those of a common conductor. The outer sheath is made of halogen-free flame retardant TPU, and has excellent wear resistance, tensile resistance, bending resistance, tearing resistance and other properties. Because the whole product is resistant to bending and abrasion. The oil resistance and the vibration resistance are good, the service life of the product is prolonged, and the use is safer.

Technical scheme

In order to realize above-mentioned technical purpose, the utility model provides a pair of resistant new forms of energy electric automobile car interior cable of buckling, its characterized in that: the cable comprises a conductor wire core, wherein an insulating layer is coated outside the conductor wire core;

the conductor wire core comprises aramid fiber wires, copper foil wires and bare copper wires, the inner layer of the conductor wire core is a plurality of strands of copper foil wires, the aramid fiber wires are filled in the middle of the plurality of strands of copper foil wires, and the bare copper wires are stranded on the outer layers of the plurality of strands of copper foil wires.

Further, the insulating layer is halogen-free flame retardant TPU, and the thickness of the insulating layer is 0.3-1.5 mm.

Advantageous effects

The utility model provides a pair of resistant new forms of energy electric automobile car interior cable of buckling, wherein the inlayer of conductor is filled for aramid fiber silk, and aramid fiber has good properties such as superhigh strength, high modulus, light in weight, and intensity is 5 ~ 6 times of steel wire, and the modulus is 2 ~ 3 times of steel wire or glass fiber, and toughness is 2 times of steel wire. The copper foil wire is stranded outside the aramid fiber wire, the copper foil wire is good in elasticity, flexibility and bending strength, the bending resistance and the like are far higher than those of a common conductor, and the bending resistance of the conductor is improved. In addition, the copper foil wire has good conductivity, and the current carrying capacity of the wire and cable is improved. The insulating layer is made of a halogen-free flame-retardant TPU material, the TPU material has stronger scratch and abrasion resistance than other materials, the mechanical property is very superior, vibration and scratch and abrasion in the vehicle can be prevented, the cable is protected from being damaged, and the TPU material also has stronger resistance to engine oil, gasoline and diesel oil, and protects the cable from being corroded by oil to cause circuit faults. Thereby making the utility model provides a cable has better resistant advantages such as buckling, wear-resisting, resistant oily, anti-vibration.
