The invention relates to the technical field of high-voltage cables, in particular to an in-vehicle high-voltage cable of a new energy automobile, which comprises a conductor, an insulating layer, a shielding layer, an aluminum foil layer, an inner sheath and an outer sheath, when the inner sheath rotates, the inner sheath drives the outer sheath far away from one end of a connecting ring to move, and under the action of a reinforcing piece in the outer sheath, the outer sheath is twisted, so that the inner sheath is prevented from rotating; the end, away from the connecting ring, of the outer sheath moves relative to the axis of the inner sheath, the distance between every two adjacent sliding rings on the outer sheath changes, the air pressure of a cavity formed by every two adjacent sliding rings, the inner side wall of the outer sheath and the outer side wall of the inner sheath is increased, and the increased air pressure can extrude the outer sheath. The force applied to the outer sheath by the hoop or the ribbon to extrude the inner sheath is reduced, so that the inner sheath and the internal structure are prevented from generating torque.

    本发明涉及高压电缆技术领域,具体涉及一种新能源汽车车内高压电缆,其包括导体、绝缘层、屏蔽层、铝箔层、内护套和外护套,则在内护套转动时,内护套带动远离连接环一端的外护套运动,在外护套内部加强件的作用下,外护套发生扭曲,且外护套远离连接环的一端相对内护套轴线运动,外护套上相邻两个滑动环之间的距离发生变化,则相邻两个滑动环、外护套内侧壁和内护套外侧壁之间构成的腔室气压增大,增大的气压能够对外护套进行挤压,减小抱箍或扎带对外护套施加挤压内护套的力,进而避免内护套及内部结构产生扭矩。
