Abstract
The utility model relates to a protective sleeve, a wire harness and a vehicle, the protective sleeve comprises an insulation sleeve and a shielding film layer arranged on the inner surface of the insulation sleeve, the wire harness comprises a guide core and the protective sleeve, and the protective sleeve is arranged outside the guide core in a sleeving mode. According to the technical scheme, the shielding film layer shields the electromagnetic waves generated by the conductive cores, and the shielding film layer is arranged on the inner surface of the insulating sleeve, so that the shielding film layer is not easy to break and scatter into chips to be dispersed in the wire harness in the wire harness manufacturing process, the risk of wire harness electric leakage caused by the fact that the insulating sleeve is punctured by the chips can be reduced, and the wire harness reliability is improved. And the risk of short circuit of the wire harness caused by accidental conduction of the shielding film layer and the guide core by chippings can be reduced, so that the electrical performance of the wire harness is improved.
