It is a schematic front view which shows the open ring attitude | position of a holding member same as the above. It is a schematic front view which shows the closed ring attitude | position of a holding member same as the above. It is a schematic side view which shows the wire harness which concerns on 2nd Embodiment. FIG. 6 is a sectional view taken along line VI-VI in FIG. 5.

{First embodiment}
Hereinafter, the wire harness 1 which concerns on 1st Embodiment is demonstrated. 1 and 2 are schematic perspective views showing the wire harness 1, FIG. 3 is a schematic front view showing an open ring posture of the holding member 6, and FIG. 4 shows a closed ring posture of the holding member 6. It is a schematic front view. Note that FIG. 2 is obtained by bending a middle portion of the path restriction portion in the wire harness 1.

  The wire harness 1 includes a wire harness main body 2 and a path regulating member 3. The wire harness 1 is fixed to the vehicle using a clamp or the like attached to the path regulating member 3.

  The wire harness main body 2 is configured by binding a plurality of electric wires. More specifically, the wire harness main body 2 has a configuration in which a plurality of electric wires are bundled while being branched according to a wiring form to a vehicle to be arranged. In FIG.1 and FIG.2, the path | route control part is shown among the wire harness main-body parts 2. FIG. But the wire harness main-body part 2 may be comprised with the single electric wire which does not necessarily need to branch. Further, other optical cables or the like may be bound to the wire harness main body 2. A route restriction member 3 is disposed in a route restriction portion that is a part of the wire harness main body 2. In addition, a path | route control part should just be at least one part of the wire harness main-body part 2, and may be a part of the wire harness main-body part 2, or the whole.

  The path regulating member 3 includes a linear member 4 and a plurality of holding members 6. The linear member 4 is formed into a member that can be plastically deformed and that maintains the path regulating portion in a shape along a certain path after plastic deformation. As the linear member 4, a metal wire such as an iron wire, a copper wire, a stainless steel wire, or an alloy wire thereof, or a resin that exhibits a certain degree of rigidity after plastic deformation can be used.

  In order for the linear member 4 to maintain the path restriction portion in the shape after bending deformation, the linear member 4 needs to have a certain degree of rigidity after bending deformation due to plastic deformation. Usually, the single linear member 4 disposed in the path restricting portion as a whole has rigidity exceeding the force that the path restricting portion of the wire harness main body 2 after bending deformation returns to the original shape. At the same time, it is preferable to have rigidity that does not cause deformation due to human power and vibration generated during vehicle travel.

  Thus, the rigidity that each linear member 4 should have after plastic deformation is the material, thickness, and number of the linear member 4, and the thickness of the path restriction portion to be regulated, the number of wires, the wire material, and the like. Depending on the regulated shape (bending deformation amount) and the like, it is set experimentally and empirically. For example, when the path regulation part to be regulated is thick and the number of electric wires is large, the force that the path regulation part after bending deformation tries to return to becomes large. In such a case, the linear member 4 may be made of a material having greater rigidity or a large diameter, or a large number of linear members 4 may be used. Here, when a stainless steel wire is used as the linear member 4, if the diameter is about 5.0Φ, the rigidity that the linear member 4 should have after plastic deformation can be satisfied.

  The linear member 4 is covered with, for example, a resin tube member 5. A plurality of (six in this embodiment) holding members 6 are integrally formed on the tube member 5 at intervals along the extending direction. Here, the tube member 5 and the plurality of holding members 6 are integrally formed by molding. Note that the number of the holding members 6 may be appropriately increased or decreased according to the length of the linear member 4 and the shape of the path regulating portion, or the interval at which the holding members 6 are formed may be changed.

  As shown in FIG. 3, the holding member 6 is formed in an arc shape having an open front end, and the tube member 5 and the holding member 6 are integrally formed so that the central portion of the arc is continuous with the tube member 5. The holding member 6 holds the wire harness main body 2 and is formed to be elastically deformable by, for example, a resin, and has an open ring posture in which the tip portion 6a and the tip portion 6b are separated from each other, and the tip portion 6a shown in FIG. And a closed ring posture in which the tip 6b is connected. A space 9 for holding the wire harness main body 2 is formed on the inner peripheral side of the holding member 6 in the closed ring posture, and a line connecting the centers of the spaces 9 of the plurality of holding members 6 is formed on the tube member 5. The plurality of holding members 6 are formed so as to be parallel to the extending direction. For this reason, the wire harness main-body part 2 can be attached in parallel with the extending direction of the tube member 5 by the plurality of holding members 6.

  A protruding portion 7 that protrudes outward is formed at one tip portion 6 a of the holding member 6, and a concave portion 8 in which the protruding portion 7 is fitted is formed at the other tip portion 6 b of the holding member 6. Yes. By moving the tip portions of the holding members 6 in the open ring posture, the entire holding member 6 is bent, and the protruding portions 7 and the recessed portions 8 can be connected by simply fitting the protruding portions 7 into the recessed portions 8. In a state where the protrusion 7 and the recess 8 are connected, a frictional force acts on the contact surface between the protrusion 7 and the recess 8 so that the connection between the tip 6a and the tip 6b can be maintained. Here, the holding member 6 can maintain the state deformed to the closed ring posture, and has rigidity enough to hold the attached wire harness main body 2.

  Further, by releasing the fitting between the concave portion 8 and the protruding portion 7 and moving the distal end portion of the holding member 6 to separate the distal end portion 6a and the distal end portion 6b, the holding member 6 is elastically returned to the open ring posture. Can be made.

  As shown in FIG. 3, in a state where the holding member 6 is in the open ring posture, the wire harness main body 2 is in the open ring posture so that it can pass between the tip portion 6a and the tip portion 6b of the holding member 6. The distance between the distal end portion 6a and the distal end portion 6b is formed to be larger (slightly larger) than the diameter of the wire harness main body 2. For this reason, when the holding member 6 is in the open ring posture, the wire harness main body 2 can be set in the space 9 of the holding member 6 from the tip portion 6a and the tip portion 6b side. In addition, the distance of the front-end | tip part 6a and the front-end | tip part 6b in an open ring attitude | position may be formed in the dimension smaller than the diameter of the wire harness main-body part 2. FIG. In this case, after moving the front-end | tip part of the holding member 6 and extending the distance of the front-end | tip part 6a and the front-end | tip part 6b, the wire harness main-body part 2 is set with respect to the holding member 6. FIG.

  As shown in FIG. 4, the length of the inner peripheral portion of the holding member 6 is larger (slightly larger) than the outer peripheral length of the wire harness main body 2 in a state where the holding member 6 is in the closed ring posture. Has been. For this reason, when the holding member 6 is in the closed ring posture, the wire harness main body 2 can be held in the space 9 of the holding member 6. Further, since the distal end portion 6 a and the distal end portion 6 b are connected by fitting the concave portion 8 and the protruding portion 7, the wire harness main body portion 2 is prevented from falling off the holding member 6.

  The holding member may be a wire. In this case, the wire as the holding member is insert-molded when the linear member is molded. By using the wire as the holding member, the holding member can maintain the deformed state in the closed ring posture and can maintain rigidity enough to hold the wire harness body 2, so that the holding member is closed. The tip portions do not have to be connected in a ring posture state. The holding member may be a binding band. In this case, the resin binding band and the linear member are integrally molded.

  According to the wire harness 1 configured as described above, the plurality of holding members 6 formed integrally with the linear member 4 are attached to the wire harness main body 2, whereby the linear member 4 is connected to the wire harness main body 2. Therefore, the path regulation of the wire harness 1 can be easily performed.

  Since the plurality of holding members 6 are formed to be deformable into an open ring posture in which the tip portion 6a and the tip portion 6b are separated from each other, and a closed ring posture in which the tip portion 6a and the tip portion 6b are connected, the wire harness main body portion By setting the plurality of holding members 6 in a closed ring posture in a state where 2 is set, the wire harness main body 2 can be easily attached and the wire harness main body 2 can be prevented from falling off the holding member 6. .

  The path regulating member 3 is composed of a linear member 4 and a plurality of holding members 6. When the linear member 4 is attached to the wire harness main body 2, no separate attachment parts such as a cable protection member are required. The number of man-hours for attaching the linear member to the part becomes unnecessary, and the man-hours for manufacturing the wire harness 1 can be reduced. In addition, since the mounting part is not required, it can be realized with a simple configuration without increasing the size of the path regulating member 3, so that the space for arranging the wire harness 1 is hardly increased. Route regulation can be performed. Furthermore, since the wire harness main body 2 is held by the plurality of holding members 6, it is possible to suppress the wire harness main body 2 from being separated from the path restriction member 3, particularly at the bent portion in the path restriction portion.

<Manufacturing method>
Next, the manufacturing method of the wire harness 1 is demonstrated. First, the wire harness body 2 is wired and bound on the assembly drawing board. The wire harness main body 2 is set in the space 9 of the plurality of holding members 6 while keeping the wire harness main body 2 along the tube member 5 with the plurality of holding members 6 in an open ring posture. Then, the wire harness main body 2 is attached by elastically deforming the plurality of holding members 6 to the closed ring posture.

  Next, the wire harness main body 2 to which the path regulating member 3 is attached is set in a jig having a shape bent according to the wiring path in the vehicle body. In a state where it is set on the jig, the path regulating portions of the path regulating member 3 and the wire harness main body 2 are pressed by a roller or the like, so that the path regulating portions of the path regulating member 3 and the wire harness main body 2 are bent and deformed.

  Further, as another manufacturing method, after the path regulating portion of the path regulating member 3 is bent and deformed, the path regulating member 3 is set on the three-dimensional drawing board, and the plurality of holding members 6 are set in an open ring posture. The wire harness main body 2 is set in the space 9 of the plurality of holding members 6 while keeping the wire harness main body 2 along the tube member 5. Then, it is also possible to attach the wire harness main body 2 by elastically deforming the plurality of holding members 6 to the closed ring posture.

  As described above, according to the method for manufacturing the wire harness 1, in the manufacturing process of the wire harness 1, since the linear path regulating member 3 can be bent and deformed according to the path, the versatility of the path regulating member 3 is improved. To do.

{Second Embodiment}
A wire harness 1A according to the second embodiment will be described. FIG. 5 is a schematic side view showing the wire harness 1A, and FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The wire harness 1 </ b> A includes a wire harness main body 2, a corrugated tube 10, and a path regulating member 3. The corrugated tube 10 is a cylindrical member in which the annular convex portions 11 and the annular concave portions 12 are alternately formed along the extending direction, and is formed of a resin or the like. Since the corrugated tube 10 is easily elastically deformed at a step portion between the annular convex portion 11 and the annular concave portion 12, it itself has a property of being easily bent and deformed. Usually, as the corrugated tube 10, a corrugated tube 10 having an inner diameter larger than the outer diameter (usually somewhat larger) of the portion of the wire harness main body 2 to be mounted is used.

  Moreover, the slit 13 is formed in the one side part of the corrugated tube 10 along the extension direction. Then, the wire harness main body 2 can be easily disposed in the corrugated tube 10 so as to be opened by the slit 13.

  The path regulating member 3 includes a linear member 4 and a plurality of holding members 6. The plurality (ten in the present embodiment) of the holding members 6 are formed at the same interval as the interval in which the plurality of annular recesses 12 are formed in the corrugated tube 10, and a plurality (ten in the present embodiment) of the corrugated tube 10. Each is fitted into the annular recess 12. The plurality of holding members 6 may be fitted into some annular recesses 12 of the plurality of annular recesses 12. Further, in a plurality of types of corrugated tubes assumed to be used, the least common multiple of the intervals at which the annular recesses are formed may be set as the intervals at which the plurality of holding members are formed. Thus, for a plurality of types of corrugated tubes that are assumed to be used, a single type of path control member is used to control the path without preparing a plurality of types of path control members having different intervals at which a plurality of holding members are formed. Since it can be performed, the versatility of the path regulating member is improved.

  The distance between the distal end portion 6a and the distal end portion 6b in the open ring posture so that the corrugated tube 10 can pass between the distal end portion 6a and the distal end portion 6b of the holding member 6 in a state where the holding member 6 is in the open ring posture. However, it is formed in a dimension larger (slightly larger) than the diameter of the annular recess 12 in the corrugated tube 10. For this reason, when the holding member 6 is in the open ring posture, the corrugated tube 10 can be set in the space 9 of the holding member 6. Note that the distance between the distal end portion 6 a and the distal end portion 6 b in the open ring posture may be formed to be smaller than the diameter of the annular recess 12 in the corrugated tube 10. In this case, the corrugated tube 10 is set with respect to the holding member 6 after moving the tip portions of the holding members 6 to increase the distance between the tip portions 6 a and 6 b.

  In a state where the holding member 6 is in the closed ring posture, the length of the inner peripheral portion of the holding member 6 is formed to be larger (slightly larger) than the outer peripheral length of the corrugated tube 10. For this reason, when the holding member 6 is in the closed ring posture, the annular recess 12 in the corrugated tube 10 can be held in the space 9 of the holding member 6. Further, since the distal end portion 6 a and the distal end portion 6 b are connected by fitting the concave portion 8 and the protruding portion 7, the corrugated tube 10 is prevented from falling off the holding member 6. In addition, the front-end | tip part 6a and the front-end | tip part 6b do not need to be connected when the path | route control member 3 can be mounted | worn with respect to the corrugated tube 10 only by fitting the front-end | tip part 6a and the front-end | tip part 6b in the annular recessed part 12.

  According to the wire harness 1 </ b> A configured as described above, since the plurality of holding members 6 are fitted into at least some of the annular recesses 12 among the plurality of annular recesses 12, the holding members with respect to the extending direction of the corrugated tube 10. 6 can be easily positioned.

<Manufacturing method>
Next, a method for manufacturing the wire harness 1A will be described. First, after wiring and binding the wire harness main body 2 on the assembly drawing board, the corrugated tube 10 is opened by the slit 13 to accommodate the wire harness main body 2 in the corrugated tube 10. The corrugated tubes 10 are set in the spaces 9 of the plurality of holding members 6 while keeping the corrugated tubes 10 accommodating the wire harness main body 2 on the linear members 4 with the plurality of holding members 6 in an open ring posture. Then, the plurality of holding members 6 are elastically deformed to a closed ring posture, and the corrugated tube 10 is attached.

  Next, the corrugated tube 10 to which the path regulating member 3 is attached is set in a jig having a shape bent according to the wiring path in the vehicle body. The path regulating member 3 and the corrugated tube 10 and the path regulating portion of the wire harness main body 2 are bent and deformed by pressing the path regulating member 3 and the corrugated tube 10 with a roller or the like in the state of being set on the jig.

  Further, as another manufacturing method, after the path regulating portion of the path regulating member 3 is bent and deformed, the path regulating member 3 is set on the three-dimensional drawing board, and the plurality of holding members 6 are set in an open ring posture. The corrugated tube 10 is set in the space 9 of the plurality of holding members 6 while the corrugated tube 10 in which the wire harness main body 2 is accommodated is placed on the tube member 5. Then, it is possible to attach the corrugated tube 10 by elastically deforming the plurality of holding members 6 to the closed ring posture.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
