1. A cable threading component, comprising:
a substrate, comprising a plurality of through holes;
a sealing sheet, comprising a plurality of sealing holes corresponding to positions of the through holes on the substrate; and
a mounting plate, comprising a plurality of guide holes corresponding to positions of the through holes on the substrate;
wherein, when the mounting plate is attached to the substrate, the sealing sheet is pressed between the substrate and the mounting plate, and the plurality of through holes of the substrate, the plurality of sealing holes of the sealing sheet, and the plurality of guide holes of the mounting plate are aligned to form threading holes, where the guide hole has an inner diameter larger than that of the through hole to allow cable to pass through the threading hole from side of the mounting plate;
wherein, the sealing hole comprises a tubular portion extending into the through hole, and a sealing core is provided inside the tubular portion, so that the sealing hole is closed before threading, and the sealing core peels off and position of the sealing core is occupied by the cable when the cable passes through;
wherein the sealing sheet has an outer circumferential sealing ring surrounding the plurality of sealing holes on the side facing the substrate, and the mounting plate comprises an outer circumferential protrusion corresponding to the outer circumferential sealing ring and inner protrusions surrounding respective sealing holes on the side facing the sealing sheet, where the outer circumferential protrusion and the inner protrusions abut against the sealing sheet.
