Electrical-wire-protecting member
View Patent ↗A electrical wire cover has a corrugated tube fixing portion ( 29 ) and engagement projection strips ( 49 ) which are integral parts of a cover body ( 27 ) which surrounds electrical wires, a electrical wire tie which fixes, that is, tightly fastens, one of first to third corrugated tubes, and tying member restricting portions ( 53 ) provided in the corrugated tube fixing portion ( 29 ). Each tying member restricting portion ( 53 ) has plural, that is, first to third, positioning portions ( 55, 57, and 59 ) having different electrical wire tie bridging positions.
1. An electrical wire protection member, comprising:
a body which surrounds an electrical wire to be installed;
a semi-cylindrical fixing portion which is an integral part of the body and to which an end portion of one of plural kinds of corrugated tubes having different diameters is fixed, wherein the electrical wire is inserted in the one of plural kinds of corrugated tubes;
engagement projection strips which project inward from the fixing portion so as to extend in a radial direction of the fixing portion, and which engage with respective outer circumferential grooves of the one of plural kinds of corrugated tubes;
a tying member which fixes, by tight fastening, the one of plural kinds of corrugated tubes to an inner peripheral surface of the fixing portion; and
tying member restricting portions which are formed in respective end portions of the fixing portion in an outer circumferential direction of the fixing portion and which determine a position of the tying member,
wherein each of the tying member restricting portions has plural positioning hole portions having different tying member bridging positions that correspond to the different diameters of the corrugated tubes, respectively.
2. The electrical wire protection member according to claim 1 , wherein the positioning hole portions corresponding to a corrugated tube having a maximum diameter are located outside respective positioning hole portions corresponding to a corrugated tube having another diameter, and have respective elongated bridging walls which extend in a tangential direction of the corrugated tube.
3. The electrical wire protection member according to claim 2 , wherein positioning projections which position the tying member project from tips of the elongated bridging walls, respectively.
4. The electrical wire protection member according to claim 1 , wherein each of the tying member restricting portions has a first positioning hole portion and a third positioning hole portion, and the third positioning hole portion is located outside of the first positioning hole portion.
5. The electrical wire protection member according to claim 4 , wherein each of the tying member restricting portions has a second positioning hole portion, and the third positioning hole portion is located outside of the second positioning hole portion.
6. The electrical wire protection member according to claim 1 , wherein each of the tying member restriction portions includes a projected portion which projects outward in the radial direction from each of the tying member restricting portions, and each projected portion includes at least one of the plural positioning hole portions.
