The present invention relates to a soundproof, insulating, and sealing device for an electric wire tube which can efficiently prevent noises between floors from propagating by using a soundproof and an insulating member of an elastic material inserted into an electric wire tube such as a gooseneck tube or the like connected to a terminal box or a connector connected to the electric wire tube, prevent outside cold air from reaching indoor space, and prevent frozen moisture resulting from infiltration of warm and humid indoor air into a cold wire inside the electric wire tube or the inner wall of the electric wire tube in winter time by preventing air from entering the electric wire tube. Since the sealing device has a simple structure, the sealing device can be manufactured at low costs and installed easily. And the sealing device can be easily replaced and repaired while being installed inside the electric wire tube. The soundproof, insulating, and sealing device is formed from an elastic member. A plurality of conical insertion passages are formed to penetrate the sealing device in a conical shape. A plurality of tight fit insertion passages are connected to the conical insertion passages and formed to remain sealed even when a wire is not inserted. An inclined fixing unit can be formed on the outer surface of the elastic member to become narrower towards the front of the elastic member. The conical insertion passages can be formed symmetrical about the tight fit insertion passages to make the front surface and the rear surface of the elastic member identical. |
