Composite cable for electric automobile

Abstract

The invention discloses a composite cable for an electric automobile. The composite cable comprises a cable core, wherein the cable core comprises frameworks, and the number of the frameworks is two and the frameworks have regular triangle cross sections, wherein one regular triangle framework is rotated by 180 degrees to be stacked with the other regular triangle framework up and down to form a main framework with a rhombic cross section and four auxiliary frameworks with triangular cross sections; a control wire core is arranged in the main framework, and a power wire core is arranged in each auxiliary framework; and a mica tape wrapping layer, an ethylene propylene rubber inner sheath layer, a steel wire braided general shielding layer and an ethylene propylene rubber outer sheath layerare sequentially wrapped outside the cable core from inside to outside. According to the cable, the frameworks are arranged, and the number of the frameworks is two and the frameworks have regular triangle cross sections, wherein one regular triangle framework is rotated by 180 degrees to be stacked with the other regular triangle framework up and down to form a main framework with a rhombic cross section and four auxiliary frameworks with triangular cross sections; by virtue of stability of the triangle, a high protection effect is achieved on the wire core; and meanwhile, the anti-compression and tensile properties of the cable can be improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a composite cable for electric vehicles. Background technique [0002] Since the country has vigorously advocated energy conservation and emission reduction, new energy vehicles have been actively developed at home and abroad. Since new energy vehicles are driven by pure electricity, they are different from traditional fuel vehicles. Traditional automotive lines only have good environmental resistance and mechanical properties. , but it is difficult to meet the use of electric vehicles. Electric drive devices require cables with special properties such as high current and high voltage. , Various high-tech content testing facilities for cables are more and more widely used in complex and harsh environments, harsh environments such as high humidity, flammable and explosive, and strong electromagnetic radiation continue to appear, unsafe factors are increasing day by day, and acciden...

[0002] Since the country has vigorously advocated energy conservation and emission reduction, new energy vehicles have been actively developed at home and abroad. Since new energy vehicles are driven by pure electricity, they are different from traditional fuel vehicles. Traditional automotive lines only have good environmental resistance and mechanical properties. , but it is difficult to meet the use of electric vehicles. Electric drive devices require cables with special properties such as high current and high voltage. , Various high-tech content testing facilities for cables are more and more widely used in complex and harsh environments, harsh environments such as high humidity, flammable and explosive, and strong electromagnetic radiation continue to appear, unsafe factors are increasing day by day, and accidents occur frequently , for this reason, we urgently need to design a composite cable for electric vehicles to solve the above problems
