Problems solved by technology

Such as the use of hub motors, since the hub motors are installed on the wheels, cables need to be connected to the wheels to transmit electric drive, and as the vehicle starts, the wheels are always in motion, and with the movement of the chassis shock absorption system, the cables are also always In the state of motion, the requirements for the bending resistance of the cable are extremely strict at this time. Using a conventional cable, when the vehicle is running for a certain period of time, the copper wire in the cable will break if the cable is bent too many times, so that the entire power will be broken, causing the motor to Stopping work can easily cause accidents

Abstract

The invention discloses a bending-resistant power cable for interior of an electric vehicle. The bending-resistant power cable comprises a cable body, wherein a conductor reinforcement piece, a conductor, a semi-conduction conductor shielding layer, an insulation layer, an insulation semi-conduction shielding layer, a weaving shielding layer, an external wrapping layer, a sheath layer and a sheathreinforcement layer are sequentially arranged in the cable body from inside to outside. The conductor added with a steel wire rope is provided, the semi-conduction conductor shielding layer is additionally arranged, the semi-conduction insulation shielding layer is selected and woven with a tin-plating copper conductor, the sheath outer layer is woven with aramid fiber, gluing is performed to make the sheath and an outer-layer weaving layer pasted, so that the cable is long in service lifetime, ideal in shielding effect and excellent in high-voltage resistance and is integrally softer.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically, to a bending-resistant power cable used inside an electric vehicle. Background technique [0002] With the development of electric vehicle technology and breakthroughs in wheel hub motors and other technologies, cables need to be suitable for more harsh environments, high and low temperature resistance, various oils, acids and alkalis and other liquids, friction resistance, bending resistance, etc. Performance demands are increasing. Specific parts often require specially customized cables to meet the special requirements of special parts. Such as the use of hub motors, since the hub motors are installed on the wheels, cables need to be connected to the wheels to transmit electric drive, and as the vehicle starts, the wheels are always in motion, and with the movement of the chassis shock absorption system, the cables are also always In the state of motion, the requirement...
