Electric wire protective tube
View Patent ↗An electric wire protective tube is configured such that a straight tube section in a shape of a straight tube and a bendable tube section that is bendable are provided along a longitudinal direction, and is configured to have a shape of a tube that allows an electric wire to be arranged therein. The electric wire protective tube has a tubular inner shield portion made of an electrically conductive material and forming an inner surface of the tube, and an exterior portion made of resin and forming an outer surface of the tube. The inner shield portion is provided such that it is firmly attached to an inner surface of the exterior portion in the straight tube section, and such that it is separable from an inner surface of the exterior portion in the bendable tube section.
1. An electric wire protective tube configured such that a straight tube section having a shape of a straight tube and a bendable tube section that is bendable are provided along a longitudinal direction, and configured to have a shape of a tube that allows an electric wire to be arranged therein, the electric wire protective tube comprising:
a tubular inner shield portion made of an electrically conductive material and forming an inner surface of the tube; and
an exterior portion made of resin and forming an outer surface of the tube,
wherein the inner shield portion is firmly attached to an inner surface of the exterior portion in the straight tube section, and the inner shield portion is separated from the inner surface of the exterior portion in the bendable tube section such that the inner shield portion is movable relative to the inner surface of the exterior portion.
2. The electric wire protective tube according to claim 1 , wherein inner diameter of the exterior portion is larger in the bendable tube section than in the straight tube section, and
wherein the inner shield portion is provided such that a clearance gap is formed between the inner shield portion and the inner surface of the exterior portion in the bendable tube section.
3. The electric wire protective tube according to claim 1 , wherein the exterior portion in the bendable tube section is formed in a corrugated shape.
