The invention discloses a wire waterproof structure and a processing method thereof. The wire waterproof structure comprises a wire body; the wire body comprises a wire core and an insulating sheath,and one or more sections of the wire body are provided with rubber-coated parts for exposing the wire core after the insulating sheath is annularly cut; a rubber-coated waterproof body is arranged onthe rubber-coated parts, completely coats the rubber-coated parts and extends towards the insulating sheath on the two sides for a certain distance; the rubber-coated waterproof body is arranged outside the rubber-coated parts in a wrapping manner through injection molding; and the lengths of the two ends of the rubber-coated waterproof body, exceeding the end parts of the rubber-coated part, aregreater than or equal to 10mm. Low-pressure injection molding is directly carried out in a mode of stripping the insulating sheath, thus the cost of opening a mold to customize a plug is saved, the waterproof safety is greatly
