Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of connecting lines, in particular to a drag-resistant power cord and a high-definition video power cable. BACKGROUND

[0002] A through hole for passing a power cord is formed on a partition plate of an electronic device. During installation or movement, the power cord is displaced relative to the through hole due to dragging, causing the part of the power cord in contact with the periphery of the through hole to be abraded, thereby damaging the power cord. Although winding a spiral protective sleeve on the surface of the power cord can prevent the power cord from directly contacting the periphery of the through hole and prolong the service life of the power cord, the spiral protective sleeve cannot be fixed relative to the partition plate, and when dragging occurs, the part of the spiral protective sleeve in contact with the periphery of the through hole is prone to abrasion, thereby exposing the power cord, which requires regular replacement of the spiral protective sleeve, increasing the use cost.
