The wire harness WH includes a conductive wiring material 1, a corrugated tube 2 as an exterior covering the wiring material 1 formed into a cylindrical shape and the wiring material 1 being inserted inside, and a wiring material fixed body And 100. The wire harness WH is, for example, wired in the vehicle in order to electrically connect the electric components mounted in the vehicle, and the wiring material 1 transmits an electric signal between the electric components, While supplying power, the corrugated tube 2 covers the outside of the cable 1 and protects it.

  The wiring material 1 has conductivity and extends in one direction. The wiring material 1 of the present embodiment is a metal rod (in other words, a single-core electric wire) inserted into the inside of a corrugated tube 2 having a conductive member 11 formed in a rod shape and having a cylindrical shape. is there. The wiring material 1 formed as a metal rod can ensure a relatively large current capacity with a relatively small cross-sectional area as compared to, for example, a plurality of core wires, thereby reducing the size of the wire harness WH Can be implemented. More specifically, the wiring material 1 has a conductive conductor portion 11 formed in a rod shape, and an insulating coating portion 12 covering the outer peripheral side of the conductor portion 11. The conductor portion 11 is formed of a metal member through which conductive electricity passes. The conductor portion 11 is formed in a rod shape, and here has a columnar conductor structure whose cross-sectional shape is substantially circular. The conductor portion 11 is formed to extend in the direction of linear extension, that is, to extend with substantially the same diameter with respect to the extension direction. The conductor portion 11 is made of a conductive metal, such as copper, a copper alloy, aluminum, an aluminum alloy or the like. The insulating covering portion 12 is a wire covering that covers the outer peripheral side of the conductor portion 11. The insulating covering portion 12 is provided in contact with the outer peripheral surface of the conductor portion 11. The insulating covering portion 12 is formed, for example, by extruding an insulating resin material (PP, PVC, crosslinked PE, etc., which is appropriately selected in consideration of abrasion resistance, chemical resistance, heat resistance, etc.) and the like. It is formed. The insulating covering portion 12 is formed from one end to the other end in the extending direction of the conductor portion 11.

  In addition, although the wiring material 1 was demonstrated as what is called a metal rod here, it may be not only this but the electric wire of a several core wire. In this case, the wiring member 1 is configured by simply bundling a plurality of conductive strands or by twisting a plurality of strands.

  The corrugated tube 2 is formed in a cylindrical (tubular) shape, here cylindrical, having flexibility by an insulating resin material or the like. The corrugated tube 2 illustrated in FIG. 1 and the like has a bellows shape in which a plurality of concavities and convexities along the circumferential direction are formed on the outer peripheral surface, and the wiring material 1 is inserted therein, and the inserted wiring material Protect one.

  In addition, the number of the wiring material 1 inserted in the corrugated tube 2 in this way may be one or may be plural. Further, the bellows-like portion formed in the corrugated tube 2 may be formed over the entire corrugated tube 2, and a part of the corrugated tube 2 may be formed in a bellows-like manner. In addition, the corrugated tube 2 may not have a bellows shape, and may have a cylindrical shape without unevenness.

  And the wiring material fixed body 100 of this embodiment is fixing the wiring material 1 with respect to the cylindrical corrugated tube 2 by restrict | limiting the movement to the radial direction of the wiring material 1. As shown in FIG. Here, the radial direction of the wiring material 1 is a direction orthogonal (cross) to the extending direction of the wiring material.

  Specifically, as shown in FIG. 1, FIG. 2, and FIG. 3, the wiring material fixed body 100 includes a pressing portion 101, an inscribed holding portion 102, and a rib portion 103. In the wiring material fixing body 100, for example, the pressing portion 101, the inscribed holding portion 102, and the rib portion 103 are integrally formed of an insulating resin material.

  The pressing portion 101 is a portion which is provided inside the corrugated tube 2 and presses the wiring material 1 inserted inside the corrugated tube 2 against the inner peripheral surface (inner surface) of the corrugated tube 2. Here, the pressing portion 101 includes an elastic piece 101 a that is elastically supported with respect to the inscribed holding portion 102 and that presses the wiring material 1 against the inner circumferential surface of the corrugated tube 2 by an elastic force. The elastic piece 101 a is formed in a plate shape that is curved with a smaller curvature than the outer peripheral surface of the wiring material 1. That is, the elastic piece 101 a is formed in a substantially arc shape having a curvature smaller than that of the outer peripheral surface of the wiring material 1 in the cross-sectional shape along the radial direction. The elastic pieces 101 a are provided in a positional relationship such that the wiring material 1 is positioned on the substantially arc-shaped concave side (recessed side), that is, the inner peripheral surface side, in the state of being disposed in the corrugated tube 2. The elastic piece 101 a is arranged in the corrugated tube 2, and the substantially arc-shaped axial direction is along the extending direction (axial direction) of the wiring material 1, and the inner peripheral surface is the outer peripheral surface of the wiring material 1 And abut. The elastic piece 101a constituting the pressing portion 101 is elastically supported by the inscribed holding portion 102 on one end side in the circumferential direction, in other words, one end side along the extending direction.

  The inscribed holding portion 102 is a portion connected to the pressing portion 101 and held in contact with the inner circumferential surface of the corrugated tube 2. The inscribed holding portion 102 is formed in a plate shape curved along the inner peripheral surface of the corrugated tube 2. That is, the cross-sectional shape along the radial direction of the inscribed holding portion 102 is formed in a substantially arc shape along the inner peripheral surface of the corrugated tube 2. The inscribed holding portion 102 elastically supports the elastic piece 101 a constituting the pressing portion 101 on one end side in the circumferential direction, in other words, one end side along the extending direction. The inscribed holding portion 102 and the elastic piece 101a are in a shape in which the elastic piece 101a is positioned radially inward and the inscribed holding portion 102 is positioned radially outward and overlapped in the radial direction, The elastic piece 101 a is elastically supported by the inscribed holding portion 102 at the folded portion. The inscribed holding portion 102 is disposed in the corrugated tube 2 and the substantially arc-shaped axial direction is along the extending direction (axial direction) of the wiring material 1 and the outer peripheral surface is the inner peripheral surface of the corrugated tube 2 And abut.

  The rib portion 103 is a portion that engages with the slit 2 a formed in the corrugated tube 2 and regulates rotation of the cable fixing member 100 in the circumferential direction. Here, in the corrugated tube 2, the slits 2 a are formed along the longitudinal direction (direction along the extending direction of the wiring material 1). The slits 2 a may be formed over the entire length in the longitudinal direction of the corrugated tube 2, or may be provided locally in the portion where the cable fixing member 100 is provided. The rib portion 103 protrudes radially outward from the circumferentially central portion of the outer circumferential surface of the inscribed holding portion 102 and is exposed to the outside of the corrugated tube 2 through the slit 2 a. The rib portion 103 is formed in a plate shape along the extending direction of the wiring material 1, in other words, the extending direction of the slit 2a.

  The cable fixing member 100 configured as described above is assembled to the corrugated tube 2 after the cable 1 is inserted into the corrugated tube 2, for example. In the cable fixing member 100, the rib portion 103 is inserted into the slit 2a of the corrugated tube 2 along the extending direction, and the elastic piece 101a constituting the pressing portion 101 and the inscribed holding portion 102 are inside the corrugated tube 2. The corrugated tube 2 is assembled in such a positional relationship as to be positioned.

  Then, in the wiring material fixed body 100, the elastic piece 101a which constitutes the pressing portion 101 and is elastically supported by the inscribed holding portion 102 presses the wiring material 1 against the inner peripheral surface of the corrugated tube 2 by elastic force and fixes it. . As a result, the wiring material fixed body 100 can restrict the movement of the wiring material 1 in the radial direction inside the corrugated tube 2. At this time, in the wiring material fixed body 100, the inward holding portion 102 contacts the inner peripheral surface of the corrugated tube 2 and the inward holding portion 102 is the inner circumference of the corrugated tube 2 by the reaction force of the elastic force of the elastic piece 101a. By being pressed to the surface side, it is held and fixed by a frictional force or the like generated between the outer peripheral surface of the inscribed holding portion 102 and the inner peripheral surface of the corrugated tube 2. Thereby, the wiring material fixed body 100 is positioned in the extending direction inside the corrugated tube 2 and can be made difficult to shift. Further, in the wiring material fixing body 100, the rib portion 103 penetrates the slit 2a of the corrugated tube 2, and in other words, the rib portion 103 is fitted in the slit 2a. Rotation in the circumferential direction can be restricted, in other words, positioning in the circumferential direction can be performed.

  According to the wiring material fixed body 100 described above, the conductive wiring material 1 provided inside the corrugated tube 2 formed in a tubular shape and inserted inside the corrugated tube 2 is the same as that of the corrugated tube 2. A pressing portion 101 pressing on the inner surface, and an inscribed holding portion 102 connected to the pressing portion 101 and held in contact with the inner surface of the corrugated tube 2 are provided. According to the wire harness WH of the wiring material 1 described above, the conductive wiring material 1 and the corrugated tube which is formed in a cylindrical shape and covers the wiring material 1 by the wiring material 1 being inserted inside 2 and the wiring material fixed body 100.

  Therefore, the diameter of the wiring material 1 can be fixed by pressing the wiring material 1 on the inner surface of the corrugated tube 2 and fixing the wiring material fixed body 100 and the wire harness WH by the pressing portion 101 provided in the corrugated tube 2. It is possible to regulate movement in the direction. At this time, in the wiring material fixed body 100, the inward holding portion 102 is held in contact with the inner surface of the corrugated tube 2 to thereby obtain the relative positional relationship between the wiring material fixed body 100 and the corrugated tube 2. It can be made difficult to shift, and it is possible to hold a stable positional relationship and to suppress the occurrence of rattling. As a result, the wiring material fixing body 100 and the wire harness WH can fix the wiring material 1 to the cylindrical corrugated tube 2.

  For example, in the wiring material fixed body 100 and the wire harness WH, various vibrations are generated in the vehicle to which the wire harness WH is applied due to the input from the road surface caused by the unevenness of the road surface, etc. It is also transmitted to the material 1 side. On the other hand, in the wiring material fixed body 100 and the wire harness WH of the present embodiment, the wiring material 1 is securely fixed to the cylindrical corrugated tube 2 by the wiring material fixed body 100. Even when vibration is transmitted to the wiring material 1, the wiring material 1 can be made difficult to move in the corrugated tube 2. As a result, the wiring material fixed body 100 and the wire harness WH can suppress the vibration of the wiring material 1 in the corrugated tube 2 according to the vehicle vibration and the like, and the wiring material 1 and the corrugated tube 2 Can be suppressed from being worn out or abnormal noises can be generated, and power, electrical signals, etc. can be transmitted via the wiring material 1 thereon.

  Further, for example, the wiring material fixed body 100 and the wire harness WH are made in accordance with the vehicle vibration or the like by making the pressing direction by the pressing portion 101 relatively along the vertical direction in which the vehicle vibration easily occurs. Vibration can be suppressed more suitably. In addition, in the wiring material fixing body 100 and the wire harness WH described above, the wiring material 1 is configured by a metal rod whose cross-sectional shape is relatively unlikely to be deformed as compared with the electric wire of a plurality of core wires and the like. Therefore, for example, the pressing force by the pressing portion 101 can be appropriately applied to the wiring material 1, and the wiring material 1 can be fixed to the cylindrical corrugated tube 2 more suitably. In addition, the wiring material fixing body 100 and the wire harness WH described above do not need to use, for example, a binding band or a winding tape in order to fix the wiring material 1, so the diameter of the corrugated tube 2 can be increased. In addition, the number of assembling steps can be suppressed, and the manufacturing efficiency can be improved.

  Furthermore, according to the wiring material fixed body 100 and the wire harness WH described above, the pressing portion 101 is elastically supported by the inscribed holding portion 102 and the wiring material 1 is made to the inner surface of the corrugated tube 2 by elastic force. It comprises the elastic piece 101a to press. Accordingly, in the wiring material fixed body 100 and the wire harness WH, the elastic piece 101a which is elastically supported by the inward holding portion 102 constituting the pressing portion 101 makes the wiring material 1 the inner circumferential surface of the corrugated tube 2 by elastic force. While being able to press and fix, the inward holding portion 102 can be pressed, held, and fixed to the inner peripheral surface side of the corrugated tube 2 by the reaction force of the elastic force of the elastic piece 101a.
