{Embodiment}
Hereinafter, the wire harness which concerns on embodiment is demonstrated. FIG. 1 is a perspective view showing a wire harness 10 according to the embodiment. FIG. 2 is a schematic cross-sectional view showing the wire harness 10 according to the embodiment. FIG. 3 is a perspective view showing a state before the exterior member 30 is rolled. FIG. 4 is a bottom view showing a state before the exterior member 30 is rolled.

  The wire harness 10 is used as wiring for electrically connecting various electric devices mounted on a vehicle or the like. Here, the wire harness 10 is demonstrated as what is routed around the instrument panel, for example in a vehicle. Of course, the wiring place of the wire harness 10 in the vehicle is not limited to the above-mentioned place, and may be routed around a roof, a door, or the like. Specifically, the wire harness 10 includes an exterior member 30 and an electric wire 12. The wire harness 10 further includes a connector 20 and a fixing member 40.

  Here, the wire harness 10 is demonstrated as what is routed along the rod-shaped member 70. In the example shown in FIG. 1, the rod-shaped member 70 is a member extending in a three-dimensional direction. In the example shown in FIG. 1, the rod-shaped member 70 is formed in a circular cross section, but this is not essential and may be a square shape or the like. As such a rod-shaped member 70, for example, a member called reinforcement can be considered. When extending the wire harness 10 along the rod-shaped member 70, the wire harness 10 is also bent in a three-dimensional direction. Here, around the instrument panel, the wiring space for the wire harness 10 is narrow, and there may be a place where the exterior member 30 attached to the wire harness 10 needs to have a flat shape. On the other hand, when the exterior member 30 attached to the wire harness 10 has a flat shape, it becomes difficult to bend the wire harness 10 in the flat plane, and the rod-shaped member 70 extending in the three-dimensional direction is made to follow. It becomes difficult. Therefore, in the wire harness 10 according to the present invention, a part of the region of the exterior member 30 is flat and at least a part of the other region is easily bent.

  The exterior member 30 is formed in a sheet shape. In the example shown in FIG. 1, the exterior member 30 is formed in a rectangular sheet shape. However, the shape of the exterior member 30 is not limited to the above-described one, and can be appropriately changed according to the arrangement form of the electric wires 12. The exterior member 30 is a member that is sheathed on the electric wire 12. The exterior member 30 is a member having at least one function among the functions such as sound insulation (silence, sound absorption, sound insulation, etc.), protection (wear resistance, tension resistance, penetration resistance, etc.), heat radiation, shield, waterproof, etc. It is. As the function of the exterior member 30, an appropriate function is selected according to the nature of the electric wire 12 and the environment where the electric wire 12 is disposed. Here, since the electric wire 12 is disposed at a place where there is a risk of rubbing against surrounding members, an example in which the exterior member 30 is a protective sheet having wear resistance will be described.

  Such a protective sheet is formed of a sheet material such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), and non-woven fabric. When the protective sheet is formed of a nonwoven fabric, hot pressing or the like may be performed. Moreover, what embossed the spunbond nonwoven fabric etc. may be used. Thereby, a protection sheet can be hardened. In addition, the abrasion resistance of such a protective sheet may be obtained from physical properties as a structure, or may be obtained from physical properties as a material. For example, in the example shown in FIG. 1, the protective sheet is formed flat, but it is considered that the wear resistance of the protective sheet can be improved by adopting a structure in which the outer surface of the protective sheet is provided with irregularities. It is done. In addition, for example, by adopting a structure in which a nonwoven fabric is hot pressed as described above, it is considered that the protective sheet can be hardened and the wear resistance can be improved. Further, for example, it is considered that the wear resistance can be improved by adopting a hard material as a material constituting the protective sheet.

  As described above, the exterior member 30 is flat in some areas and rounded in at least some other areas. In the example shown in FIG. 1, both end sides along the extending direction of the electric wire 12 are rounded, and the region between them is formed flat. Of course, the end side along the extending direction of the electric wire 12 may be a flat region, or a rounded region may exist between the flat regions. Moreover, the one end side along the extending direction of the electric wire 12 may be a flat area and the other end side may be a rounded area. Further, more flat regions and rounded regions may be arranged than in the illustrated example.

  In the rounded region of the exterior member 30, the exterior member 30 is at least double with the one main surface 31a as the inner peripheral side. Thereby, the exterior member 30 can cover the entire circumference of the electric wire 12. But the exterior member 30 may be curled by making the other main surface 31b into the inner peripheral side. Moreover, the exterior member 30 does not need to be double.

  Here, the slit 32 reaching the outer edge from the inside of the exterior member 30 (inside portion viewed from the normal direction of the main surface 31a) at the boundary between the flattened region and the rounded region of the exterior member 30. Is formed. In the example illustrated in FIG. 1, the slit 32 is formed along a direction orthogonal to the extending direction of the electric wire 12, but is not limited thereto. Further, in the example shown in FIG. 1, the slit 32 has a cut shape with no width, but may have a concave shape with a width.

  The electric wire 12 is disposed so as to overlap the exterior member 30 in at least a part of the region along the longitudinal direction. In the example shown in FIG. 1, the electric wire 12 is disposed only on the one main surface 31 a side of the exterior member 30, but may be moved to the other main surface 31 b side in the middle. It is sufficient that at least one electric wire 12 is included. Here, a plurality of electric wires 12 (three in the example shown in FIG. 1) are included. An insulated wire 12 including a core wire 14 and an insulating coating 16 covering the core wire 14 is employed as the wire 12 (see FIG. 6). The core wire 14 is formed of a conductive material such as copper or aluminum. The core wire 14 may be a single wire or a stranded wire. The insulation coating 16 may be formed by extruding a resin such as PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene) or the like on the outer periphery of the core wire 14, or on the outer periphery of the core wire 14. It may be formed by baking applied varnish or the like.

  At least a part of a portion where the insulating coating 16 and the exterior member 30 of the electric wire 12 overlap is welded. Thereby, the electric wire 12 and the exterior member 30 are being fixed.

  Here, ultrasonic welding is employed as the welding means. FIG. 5 is an explanatory view showing a state in which ultrasonic welding is performed. As shown in FIG. 5, the ultrasonic welding is generally performed by sandwiching two members (here, the electric wire 12 and the exterior member 30) to be welded between the horn 82 and the anvil 84 in the ultrasonic welding machine 80. . The two members disposed between the horn 82 and the anvil 84 are in a state where the surfaces to be welded are in contact with each other.

  The horn 82 abuts on one of the two members and applies ultrasonic vibration to the one member. As a transmission mode of ultrasonic vibration from the horn 82, there are longitudinal vibration, lateral vibration, and the like, which can be appropriately selected according to the shape, physical properties, etc. of the member to be welded.

  The anvil 84 supports the other member of the two members. In the example shown in FIG. 5, the electric wire support surface in the anvil 84 is formed in a flat surface shape, but may be formed in a curved surface shape.

  When two members to be welded are sandwiched between the horn 82 and the anvil 84 and ultrasonic vibration is applied from the horn 82 to one member, friction or compression is caused due to the applied ultrasonic vibration. Etc. occur and heat energy is generated. As a result, a part of the contact surface is melted by the thermal energy, and both are joined. Note that only one of the two members may be melted, or both may be melted. This is considered to be determined according to the physical properties of the materials constituting the two members.

  When performing ultrasonic welding, generally, a trace of pressing the horn 82 (hereinafter referred to as horn trace 34) may remain on the member. Accordingly, the horn mark 34 may remain in the wire harness 10 as well. For example, the horn mark 34 may have a shape corresponding to the concavo-convex shape formed on the horn 82.

  The region welded to the exterior member 30 in the longitudinal direction of the electric wire 12 may continue without being continuously interrupted along the longitudinal direction of the electric wire 12, or may be a section where the region is partially interrupted along the longitudinal direction of the electric wire 12. May be included. In the example shown in FIG. 4, ultrasonic welding is intermittently performed so as to include a section that is partially interrupted along the longitudinal direction of the electric wire 12. At this time, the range of one welding location, the interval between adjacent welding locations, and the like may be set as appropriate according to the bonding strength and the like. Further, in the example shown in FIG. 4, ultrasonic welding is intermittently performed at a constant pitch along the longitudinal direction of the electric wire 12, but portions having different pitches may exist.

  The region welded to the exterior member 30 in the circumferential direction of the electric wire 12 may be the entire region along the circumferential direction, or may be a partial region. When a partial region along the circumferential direction of the electric wire 12 is welded, the region may be a region equal to or smaller than a half circle, or equal to or smaller than a quarter circle. It may be a region.

  When ultrasonic welding is performed, at least one of the two members (here, the insulating coating 16 and the exterior member 30 of the electric wire 12) includes a thermoplastic resin on the contact surface. At this time, it is preferable that both of the two members include a thermoplastic resin at the contact surface, and the melting points of the respective thermoplastic resins are approximately the same. Furthermore, it is more preferable that both of the two members contain the same thermoplastic resin at the contact surface. Thereby, both of the two members are melted, and the bonding strength can be improved.

  The electric wire 12 may be a power supply line or a signal line for use. In addition, the thickness may be thick or thin. Moreover, regarding a cross-sectional shape, a round electric wire may be sufficient and a square electric wire may be sufficient. Here, it is generally preferable that the contact surfaces of the two members at the start of ultrasonic welding have a convex shape in order to reduce the contact area. From this point of view, in the case of a round electric wire, since it has a convex shape at any position in the circumferential direction, it can be said that it is a shape suitable for ultrasonic welding without considering the arrangement direction.

  The end of the electric wire 12 is assembled into the connector 20. And in the state which this wire harness 10 was arrange | positioned in the arrangement | positioning object location in a vehicle etc., the connector 20 is connected to the connector 20 by the side of the various electric equipment mounted in the vehicle etc. Thereby, this wire harness 10 is used as wiring which electrically connects the various electric devices mounted in the vehicle etc.

  Here, the connector 20 is also welded to the exterior member 30. A part of the outer surface of the connector housing 21 in the connector 20 overlaps with the exterior member 30, and at least a part of the overlapping part is welded. The connector housing 21 is a member integrally molded (injection molding) using, for example, a resin or the like as a material. In the example illustrated in FIG. 4, the horn mark 34 remains on the exterior member 30 side, but the horn mark may remain on the connector housing 21 side.

  In addition, it is preferable that the welding location in the connector housing 21 is a location which does not inhibit the fitting to the other party connector. For example, in the example shown in FIG. 4, the peripheral portion of the portion of the connector housing 21 where the electric wires 12 extend to the outside is welded, but a protruding piece is provided by protruding a part of the outer surface of the connector housing 21. The protruding piece may be welded.

  However, it is not essential that the connector 20 is welded to the exterior member 30. In this case, the connector 20 may be fixed to the exterior member 30 by another means such as an adhesive tape or an adhesive, or may not be fixed.

  Here, as shown in FIG. 2, a pressure contact type connector 20 is employed as the connector 20. More specifically, the connector housing 21 includes a first member 23 and a second member 24 that can be combined with the first member 23. The 1st member 23 can hold | maintain the press-contact terminal 26 in the aspect which exposes the press-contact part 27 which can be press-contacted to the insulated wire 12 among the press-contact terminals 26 outside. Moreover, the 1st member 23 accommodates the other party connection part 28 connected with the other party conductor among the press-contact terminals 26 in the aspect which can be connected with the other party conductor. The second member 24 is disposed to face the portion of the first member 23 that holds the press contact portion 27, and can press the insulated wire 12 toward the press contact portion 27. Then, the insulated wire 12 is pressed toward the press contact portion 27 by the second member 24 in a state where the insulated wire 12 is positioned without being peeled on the press contact portion 27 of the press contact terminal 26 held by the first member 23. As a result, a part of the pressure contact portion 27 breaks through the insulating coating 16 of the insulated wire 12 and is connected to the core wire 14.

  Here, in the example shown in FIG. 4, the three electric wires 12 are all welded to the exterior member 30. But when the wire harness 10 contains two or more electric wires 12, the electric wire 12 which is not welded with the exterior member 30 may be contained. Moreover, in the example shown in FIG. 4, all the three electric wires 12 are welded similarly. But when the wire harness 10 contains two or more electric wires 12 welded with the exterior member 30, at least one part of welding aspects, such as a welding means and a welding area | region, may differ.

  In the example shown in FIG. 4, all three electric wires 12 are connected to the same connector 20. But when the wire harness 10 contains two or more electric wires 12, the electric wire 12 connected to the different connector 20 may be contained.

  Moreover, in the example shown in FIG. 4, the electric wire 12 is arrange | positioned at linear form. But the electric wire 12 may be bent and arrange | positioned. And when the wire harness 10 contains two or more electric wires 12, the electric wire 12 arrange | positioned linearly and the electric wire 12 arrange | positioned bent may exist together. In this case, branches may be formed in the plurality of electric wires 12 on the exterior member 30.

  In the example shown in FIG. 4, the electric wire 12 is disposed at a position near the center in the width direction with respect to the exterior member 30. But the path | route by which the electric wire 12 is arrange | positioned with respect to the exterior member 30 is not restricted to an above-described thing. For example, the electric wire 12 may be disposed at a position near the end in the width direction with respect to the exterior member 30. For example, the electric wire 12 may extend obliquely with respect to the exterior member 30.

  The fixing member 40 is a member for fixing the electric wire 12 to an attachment target such as a vehicle body panel or a rod-shaped member 70. Here, the fixing member 40 is also welded to the exterior member 30. In the example shown in FIG. 3, the horn mark 34 remains on the exterior member 30 side, but the horn mark may remain on the fixed member 40 side. Here, the fixing member 40 has a pillar portion 44 and a wing portion 46 extending from the tip of the pillar portion 44, and is a member called a clamp or a clip integrally molded (injection molding) using a resin or the like as a material.

  The fixing member 40 is provided with a plate portion 42 that supports the column portion 44, and the plate portion 42 and the exterior member 30 are welded together. In addition, as the said board part 42, you may use the existing thing, such as the protrusion piece wound by the tape in what is called a tape winding clamp, and you may newly provide a dedicated thing.

  In the example illustrated in FIG. 1, the fixing member 40 is attached so as to protrude from the other main surface 31 b side opposite to the one main surface 31 a on which the electric wire 12 is disposed. Further, the fixing member 40 is provided in a portion where the exterior members 30 overlap with each other in a rounded region. As a result, as shown in FIG. 2, when the exterior member 30 is rolled so as to surround the electric wire 12, the state is rounded by inserting the fixing member 40 into a portion of the exterior member 30 that overlaps the fixing member 40. Can be maintained. In addition, as shown in FIG. 3, it is good for the area | region where the exterior member 30 is rounded to form the through-hole 33 in the part which overlaps with the part in which the fixing member 40 is provided when the exterior member 30 is rounded. . Thereby, it becomes easy to insert the fixing member 40 into a portion overlapping with the fixing member 40. But the fixing member 40 may be attached so that it may protrude from the one main surface 31a side. Further, the fixing member 40 may be provided in a flat region.

  According to the wire harness 10 configured as described above, since the electric wire 12 and the exterior member 30 are welded, the exterior member 30 can be easily rolled even in a direction intersecting with the extending direction of the electric wire 12. it can. And the part rounded in the direction which cross | intersects the extension direction of the electric wire 12 among the exterior members 30 increases the freedom degree of a bending direction compared with a flat part. Thereby, both the area | region arrange | positioned flatly and the area | region arrange | positioned curvedly among the wire harnesses 10 can be easily coped with by the single exterior member 30.

  Moreover, since at least a part of the portion where the insulation coating 16 of the electric wire 12 and the exterior member 30 overlap is ultrasonically welded, it can be easily welded.

  In addition, since the slit 32 reaching the outer edge from the inside of the exterior member 30 is formed at the boundary between the flat area and the rounded area of the exterior member 30, the rounded area can be easily reduced. Can be rounded. Moreover, it is suppressed that the area | region made into the flat state rounds.

  Moreover, since the fixing member 40 for fixing the electric wire 12 to the attachment target is welded to the exterior member 30, the fixing member 40 can be easily attached.

  Moreover, since the exterior member 30 is maintained in the state rounded by the fixing member 40 provided in the rounded area | region of the exterior member 30, the exterior member 30 can be easily maintained in the rounded state.

  Further, in the rounded region of the exterior member 30, the exterior member 30 has at least a double portion with the one main surface 31 a on which the electric wires 12 are disposed as the inner peripheral side. It becomes possible to cover the entire periphery of the electric wire 12.

{Modifications}
FIG. 6 is a schematic cross-sectional view showing a modification of the wire harness 10.

  The wire harness 110 according to the modification is different from the wire harness 10 according to the embodiment in that a part of the exterior member 130 in the width direction is wound around the rod-shaped member 70.

  In the example shown in FIG. 6, one main surface 131 a on which the electric wire 12 is disposed in the exterior member 130 is directed to the rod-shaped member 70 side, but this is not essential, and the other main surface 131 b side is formed into a rod shape. It may be directed toward the member 70 side.

  FIG. 7 is a schematic perspective view showing another modification of the wire harness 10.

  The wire harness 210 according to the modification is different from the wire harness 10 according to the embodiment in that the exterior member 230 is not provided with the slit 32.

  When the exterior member 230 not provided with the slits 32 is rounded as described above, the exterior member 230 is gradually rounded from the flat area toward the rounded area. Specifically, in the example shown in FIG. 7, between a portion that is in a flat state, that is, a portion that covers the electric wire 12 from one side, and a portion that is completely covered around the electric wire 12 in the rounded region. When the electric wire 12 in the portion is viewed, the circumferential region covered by the exterior member 230 gradually changes in the longitudinal direction.

  In the case without the slit 32, it is considered that the structure of the rounded portion is as follows. That is, the portion that completely covers the periphery of the electric wire 12 in the rounded region is the portion having the smallest radius of curvature of the exterior member 30, and the curvature gradually increases from the flat portion toward the portion. The case where the radius is small is considered. Alternatively, the radius of curvature is constant between the part that is completely covered around the electric wire 12 in the rounded region and the part that is in the middle of the rounded region, but the part that is completely covered around the electric wire 12 A case where the length of the bent portion of the exterior member 30 is gradually increased may be considered. Furthermore, it is conceivable that both the radius of curvature and the length of the bent portion are changed.

  As described above, even when the exterior member 230 is not provided with the slits 32, it is possible to keep a part of the exterior member 230 round and keep the other part of the region flat. In this case, the trouble of providing the slit 32 can be saved.

{Other variations}
In the embodiment, the wire harness 10 is described as being routed along the rod-shaped member 70, but this is not essential. For example, it is also conceivable that the wire harness 10 is disposed along a flat plate member such as a vehicle body panel or a roof.

  Further, the welding means has been described as being ultrasonic welding so far, but the welding means is not limited to ultrasonic welding. For example, heat welding such as resistance welding or laser welding may be used.

  Although the protective sheet has been described as having wear resistance, this is not essential. It is also conceivable that the protective sheet has penetration resistance. Moreover, although the exterior member 30 was demonstrated as what is a protective sheet in embodiment, this is not essential. The exterior member 30 may be a soundproof sheet, a shield member, a heat radiating member, or may function as a tension member.

  In the above description, the insulating coating 16 covering the outside of the core wire 14 in the single electric wire 12 is directly welded to the exterior member 30, but this is not essential. For example, a plurality of insulation coatings such as a shielded wire including a core wire, a first insulation coating covering the core wire, a shield layer covering the first insulation coating, and a second insulation coating covering the shield layer It is also conceivable that the outermost insulating coating and the exterior member 30 are welded to each other. In addition, for example, in a cable including a plurality of electric wires 12 and a sheath covering the periphery of the plurality of electric wires 12, the sheath and the exterior member may be welded. In this case, the sheath can be regarded as one of the insulating coatings on the electric wire 12.

  Moreover, although it demonstrated so far that the press-contact connector 20 is used as the connector 20, this is not essential. For example, a crimp terminal that is crimped to the end of the electric wire 12 may be accommodated.

  In addition, each structure demonstrated by said each embodiment and each modification can be suitably combined unless it mutually contradicts. For example, it is also conceivable that the exterior member 30 is configured by combining a plurality of sheet materials each having a different function.

  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.
