Abstract
The utility model discloses an elevator travelling cable allowing automatic stripping of a protective layer. The cable comprises a flat insulating external sheath and a wire core which is arranged in the flat insulating external sheath. The flat insulating external sheath is divided into multiple accommodating cavities in a spacing way along a length direction. A connecting position between two adjacent accommodating cavities corresponding to the upper surface and the lower surface of the flat insulating external sheath is oppositely and inwardly recessed so that a tearing part is formed. At least one tearing part is internally provided with a pair of tearing lines which are arranged in the spacing way along a thickness direction of the flat insulating external sheath. The cable is simple in structure and reasonable in design. When the flat insulating external sheath needs to be stripped, an objective of stripping the flat insulating external sheath can be realized only by pulling a pair of tearing lines in the corresponding tearing part to the opposite direction. Besides, the tearing lines are stripped towards two directions so that stripping of the flat insulating external sheath is complete, rapid and labor-saving.
