Low-temperature-resistant bending-resistant cable for charging new energy automobile

Abstract

The invention discloses a low-temperature-resistant bending-resistant cable for charging a new energy automobile, which comprises a cable body and a central conductive layer, the cable body is sequentially provided with a temperature-resistant layer, an anti-bending layer and a shielding layer from inside to outside, a cavity is arranged between the temperature-resistant layer and the anti-bending layer, the cable body is provided with a fixed anti-loosening structure, the fixed anti-loosening structure comprises a first supporting disc and a second supporting disc which are installed on the surface of the cable body, a rotating handle is rotationally installed on the top of the second supporting disc, a plurality of discharging bodies are installed at one side of the first supporting disc, and the tops of the discharging bodies are of opposite discharging structures. When the outer side of the cable body receives bending force or impact force from one side, wedge-shaped protrusions deform while sliding along sliding grooves in one side of the temperature-resistant layer, and impact energy from the outside is converted into sliding energy to be absorbed; in the bending process, the friction force among the temperature-resistant layer, the bending-resistant layer and the shielding layer and the amplitude of relative position change are reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a low-temperature and bending-resistant cable for charging new energy vehicles. Background technique [0002] Compared with traditional vehicles, new energy electric vehicles have the characteristics of stable operation, no noise, no pollution, low carbon emissions, high safety, etc., and have broad market application prospects. ", with the large-scale promotion and industrial application of new energy electric vehicles, the demand for cables for electric vehicle conductive charging systems has also doubled. [0003] Moreover, in winter or cold regions, cables are required to withstand severe cold and various harsh natural environments, and have strong wear resistance, oil resistance and bending resistance, while traditional cable products can only meet part of the functions, so During the operation of the locomotive, cable cracks, softness decline, and premature aging are likely...
