{Embodiment}
Hereinafter, the wire harness according to the embodiment will be described. 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.

  The wire harness 10 is used as a wire for electrically connecting various electric devices mounted on a vehicle or the like. Here, the wire harness 10 will be described as being routed, for example, around an instrument panel in a vehicle. Of course, the wiring location of the wire harness 10 in the vehicle is not limited to the above-described location, and may be routed around a roof, a door or the like. Specifically, the wire harness 10 includes the exterior member 30, the electric wire 12, and the sewing thread 40. The wire harness 10 further includes a connector 20 and a fixing member 50.

  Here, the wire harness 10 will be described as being arranged along the rod-like member 70. In the example shown in FIG. 1, the rod-like member 70 is a member extending in a three-dimensional direction. In addition, although the rod-shaped member 70 is formed in the cross-sectional circular shape in the example shown in FIG. 1, this is not essential and an angular shape etc. may be sufficient. The rod-like member 70 may be, for example, a member called reinforcement. When the wire harness 10 extends along the rod-like member 70, the wire harness 10 is also bent in a three-dimensional direction. Here, the wiring space for the wire harness 10 is narrow around the instrument panel, and there may be a place where it is necessary to make the exterior member 30 attached to the wire harness 10 in a flat shape. On the other hand, when the exterior member 30 attached to the wire harness 10 has a flat shape, it is difficult to bend the wire harness 10 in the flat surface, and the wire harness 10 is made to extend along the rod-like member 70 extending in three dimensions. It becomes difficult. Thus, in the wire harness 10 according to the present invention, a partial region of the exterior member 30 has a flat shape, and at least another partial region has a bendable shape.

  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 one described above, and can be appropriately changed according to the arrangement of the electric wire 12 or the like. The exterior member 30 is a member that is encased in the electric wire 12. The exterior member 30 is a member having at least one of the functions such as sound proofing (silence, sound absorption, sound insulation, etc.), protection (abrasion 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 of the place where the electric wire 12 is disposed. Here, since the electric wire 12 is arrange | positioned by the location which has a possibility of rubbing with the surrounding member, the exterior member 30 demonstrates the example which is a protection sheet which has abrasion resistance.

  The protective sheet is formed of a sheet material such as PVC (polyvinyl chloride), PP (polypropylene), and non-woven fabric. When the protective sheet is formed of non-woven fabric, hot pressing or the like may be performed. Thereby, the protective sheet can be hardened. The abrasion resistance of the 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, although the protective sheet is formed flat, it is considered that the wear resistance of the protective sheet can be enhanced by adopting a structure in which the outer surface of the protective sheet is provided with irregularities. Be Further, for example, by adopting a structure in which the nonwoven fabric is hot-pressed as described above, it is considered that the protective sheet can be hardened and the abrasion resistance can be enhanced. For example, it is thought that abrasion resistance can be improved by adopting a hard material as a material which constitutes a protection sheet.

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

  In the rounded region of the exterior member 30, the exterior member 30 is at least doubled with the one major surface 31a as the inner circumferential side. Thereby, the exterior member 30 can cover the entire circumference of the electric wire 12. However, the exterior member 30 may be rounded with the other main surface 31 b as the inner peripheral side. Moreover, the exterior member 30 may not be double.

  Here, a slit 32 which reaches the outer edge from the inside of the exterior member 30 is formed at the boundary between the flat region of the exterior member 30 and the rounded region. Although the slit 32 is formed along the direction orthogonal to the extending direction of the electric wire 12 in the example shown in FIG. 1, the invention is not limited to this. Further, the slit 32 is in the form of a slit without a width in the example shown in FIG. 1, but may be in the shape of a concave with a width.

  The electric wire 12 is disposed on the one main surface 31 a side of the exterior member 30. At least one wire 12 may be included. Here, a plurality of (two in the example shown in FIG. 1) electric wires 12 are included. Here, it is assumed that the insulated wire 12 including the core wire 14 and the insulating coating 16 covering the core wire 14 is adopted as the wire 12 (see FIG. 8). 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 or the like on the outer periphery of the core wire 14, or even if a varnish or the like applied to the outer periphery of the core wire 14 is baked. Good. However, the bare core wire 14 may be adopted as the electric wire 12.

  Although the details will be described later, when employing a manufacturing process using a sewing machine or the like, such an electric wire 12 is preferably resistant to tension. Moreover, a thin thing is preferable. Also, from this point of view, it is preferable to use a signal line that can be made relatively thin rather than a power line that tends to be relatively thick.

  The end of the wire 12 is incorporated into the connector 20. Then, in a state where the wire harness 10 is disposed at an installation target location in a vehicle or the like, the connector 20 is connected to the connectors 20 on the various electric devices mounted on the vehicle or the like. Thus, the wire harness 10 is used as a wire for electrically connecting various electric devices mounted on a vehicle or the like.

  Here, the connector 20 is also sewn to the exterior member 30. A hole 22 or a recess or the like is formed in the connector housing 21 of the connector 20, and the connector housing 21 is sewn to the exterior member 30 using the hole 22 or the recess or the like. In addition, as the said hole 22 or a recessed part, the existing thing, such as what was formed in the lock part, or the thing formed in the cassette part, may be used, and a thing for exclusive use may be newly provided. However, it is not essential that the connector 20 is sewn to the exterior member 30. In this case, the connector 20 may or may not be fixed to the exterior member 30 by another means such as an adhesive tape or an adhesive.

  Here, as shown in FIG. 2, a pressure contact type connector 20 is employed as the connector 20. More specifically, the connector housing 21 is composed of a first member 23 and a second member 24 which can be combined with the first member 23. The first member 23 can hold the pressure contact terminal 26 in such a manner that the pressure contact portion 27 of the pressure contact terminal 26 which can be in pressure contact with the insulated wire 12 is exposed outward. Further, the first member 23 accommodates the mating connection portion 28 of the pressure-welding terminal 26 connected to the mating conductor in a manner connectable to the mating conductor. The second member 24 is disposed to face the portion of the first member 23 that holds the pressure contact portion 27, and can press the insulated wire 12 toward the pressure contact portion 27. Then, in a state where the insulated wire 12 is positioned on the press-contacting portion 27 of the press-contacting terminal 26 held by the first member 23 without peeling off, the insulated wire 12 is pressed toward the press-contacting portion 27 by the second member 24 As a result, a part of the pressure contact portion 27 pierces the coating of the insulated wire 12 and abuts on the core wire 14 to be connected.

  In the example shown in FIG. 3, all the three electric wires 12 are sewn to the exterior member 30 by the sewing thread 40. However, when the electric wire 12 is contained in multiple numbers by the wire harness 10, the electric wire 12 which is not sewn may be included.

  Further, in the example shown in FIG. 1, all the three electric wires 12 are connected to the same connector 20. However, when multiple wires 12 are included in the wire harness 10, the wires 12 connected to different connectors 20 may be included.

  Moreover, in the example shown in FIG. 1, the electric wire 12 is arrange | positioned in linear form. However, the electric wire 12 may be bent and disposed. And when the electric wire 12 is contained in multiple numbers by the wire harness 10, the electric wire 12 arrange | positioned linearly may be present together with the electric wire 12 arrange | positioned by bending. In this case, a branch may be formed on the plurality of electric wires 12 on the exterior member 30.

  Further, in the example shown in FIG. 1, the electric wire 12 is disposed at a position near the center in the width direction with respect to the exterior member 30. However, the path along which the electric wire 12 is disposed relative to the exterior member 30 is not limited to the one described above. For example, the electric wire 12 may be disposed at a position closer to the end in the width direction with respect to the exterior member 30. Further, for example, the electric wire 12 may extend obliquely to the exterior member 30.

  The thread 40 sews the wire 12 to the exterior member 30. The thread 40 is preferably a member that is easier to bend than the wire 12. Further, as the thread 40, it is preferable that the tensile strength is stronger than that of the electric wire 12. As this sewing thread 40, it may be formed using natural fiber as a material, and may be formed using chemical fiber as a material. The sewing thread 40 may be a single thread or a twisted thread.

  When there is a possibility that the sewing thread 40 may come in contact with a surrounding member in a state of being assembled to a vehicle, the sewing thread 40 is formed of nylon or polyester and so-called high wear resistance such as fishing line is adopted. preferable.

  Here, as shown in FIG. 2, one continuous sewing thread 40 is adopted as a sewing thread 40 for sewing one electric wire 12, and the one sewing thread 40 causes electric wires at a plurality of positions along the extending direction of the electric wire 12. 12 are sewn. At this time, one thread 40 extends partially along the other main surface 31 b of the package member 30 and partially escapes from the one main surface 31 a of the package member 30 to form a loop 85. Then, the electric wire 12 is sewed by inserting the electric wire 12 through the ring 85.

  However, it is not essential that one electric wire 12 is sewn by one continuous sewing thread 40. As the thread 40, one obtained by partially sewing the electric wire 12 at one position and cutting both ends may be present at a plurality of places along the extending direction of the electric wire 12.

  The fixing member 50 is a member for fixing the electric wire 12 to a mounting object. Here, the fixing member 50 is also sewed to the exterior member 30. Here, the fixing member 50 is a member called a clamp or a clip having a column 54 and a wing 56 extending from the tip of the column 54.

  A hole 52 or a recess or the like is formed in the fixing member 50, and the fixing member 50 is sewn to the exterior member 30 using the hole 52 or the recess or the like. As the hole 52 or the recess, an existing one may be used, or a dedicated one may be newly provided.

  In the example shown in FIG. 1, the fixing member 50 is attached so as to project from the side of the other main surface 31 b opposite to the one main surface 31 a on which the electric wire 12 is disposed. Further, the fixing member 50 is provided in a portion where the exterior members 30 overlap with each other in an area to be rounded. Thereby, as shown in FIG. 2, when the exterior member 30 is rounded so as to surround the electric wire 12, the state in which the fixing member 50 is inserted into a portion overlapping the fixing member 50 in the exterior member 30 is rolled. Can be maintained. In addition, as shown in FIG. 3, it is preferable that a through hole 34 be formed in a portion where the fixing member 50 is provided in a region where the exterior member 30 is rounded when the exterior member 30 is rounded. As a result, the portion overlapping with the fixing member 50 can be easily inserted into the fixing member 50.

  However, the fixing member 50 may be attached so as to protrude from the one main surface 31 a side. Further, the fixing member 50 may be provided in a flat area.

<Manufacturing method>
Next, a method of manufacturing the wire harness 10 according to the embodiment will be described with reference to FIGS. 4 to 7. 4 to 7 are explanatory views showing one manufacturing process of the wire harness 10 according to the embodiment.

  First, the exterior member 30, the electric wire 12, the sewing thread 40 and the needle 80 are prepared. Here, the open needle 80 with the hole 82 is used. The hole 82 is provided on the distal end side of the needle 80. A thread 40 is passed through the hole 82 as an upper thread 84.

  Next, as shown in FIG. 4, the needle 80 having the upper thread 84 passed through the hole 82 is inserted into the exterior member 30 from the other main surface 31 b side (step (a)). As a result, a portion of the upper thread 84 is pulled out together with the needle 80 toward the one main surface 31 a.

  Next, a loop 85 is formed on the upper thread 84 passed to the one main surface 31a side (step (b)). For example, as shown in FIG. 5, when the needle 80 is returned to the other main surface 31 b side, a part of the upper thread 84 which has fallen together with the needle 80 to the one main surface 31 a remains on the one main surface 31 a side It is formed.

  Next, the electric wire 12 as the lower thread 86 is inserted into the ring 85 (step (c)). Here, the wheel 85 is first spread as shown in FIG. Then, the wheel 85 is rotated around the bobbin 90 for winding and accommodating the electric wire 12, and the bobbin 90 is wound in the wheel 85.

  Thereafter, as shown in FIG. 7, by tightening the ring 85, the electric wire 12 is inserted into the ring 85. Thereby, the sewing of the electric wire 12 in the said location is completed.

  After that, while feeding the exterior member 30, by repeating the same operation, one electric wire 12 can be sewn continuously with one thread.

  Then, the connector 20 and the fixing member 50 are sewed separately to the exterior member 30 to which the electric wire 12 is sewn. These may be sewn before the electric wire 12 is sewn. When the connector 20 and the electric wire 12 are sewn, the end of the electric wire 12 is connected to the crimp connector 20.

  Furthermore, the slits 32 and the through holes 34 are formed in the exterior member 30. These may be before or after the sewing process. Then, when the sewing process is completed and the slits 32 and the through holes 34 are formed, and the state as shown in FIG. 3 is obtained, the region to be rounded in the exterior member 30 (one side portion sandwiching the slits 32) is rounded. The fixing member 50 is inserted into the overlapping portion of the exterior member 30, here the through hole 34, and the rolled state is maintained. From the above, the wire harness 10 is completed.

  A sewing machine may be used for a sewing process among the above-mentioned manufacturing methods, and hand sewing may be used. By using a sewing machine, some processes can be automated.

  When the sewing machine is used, the operation of rotating the wheel 85 around the bobbin 90 while spreading the wheel 85 is performed by a well-known hook member. Further, by making the upper yarn 84 weaker than the lower yarn 86, it can be suppressed that the electric wire 12 as the lower yarn 86 is drawn to the other main surface 31b side of the exterior member 30 by the upper yarn 84.

  According to the wire harness 10 configured as described above and the method for manufacturing the same, since the electric wire 12 is sewn to the outer covering member 30, the outer covering member 30 can be easily made in the direction intersecting the extending direction of the electric wire 12 It can be rounded to And the part rounded off in the direction which intersects the extension direction of electric wire 12 among exterior members 30 has the freedom degree of a bending direction increasing compared with the flat part. Thereby, the area | region of both the area | region arrange | positioned flatly among the wire harnesses 10 and the area | region arrange | positioned by bending can be easily coped with the one exterior member 30. FIG. Under the present circumstances, since a sewing machine can be used for a sewing process, manufacture of the wire harness 10 becomes easy.

  Moreover, since the slit 32 which reaches the outer edge from the inside of the exterior member 30 is formed at the boundary between the flat state and the rounded area of the exterior member 30, the rounded area is more easily reduced. It can be rounded. In addition, it is possible to suppress the rounding of the flat region.

  Moreover, since the fixing member 50 for fixing the electric wire 12 to attachment object is sewed on the exterior member 30, the fixing member 50 can be attached easily.

  Moreover, since the exterior member 30 is maintained in the rounded state by the fixing member 50 provided in the rounded area of the exterior member 30, the exterior member 30 can be easily maintained in the rounded state.

  Further, since there is a portion in which the exterior member 30 is at least doubled with the one main surface 31 a on the inner peripheral side in the rounded region of the exterior member 30, the exterior member 30 covers the entire periphery of the electric wire 12. It becomes possible.

{Modification}
FIG. 8 is a schematic cross-sectional view showing a modified example of the wire harness 10.

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

  In the example shown in FIG. 8, one main surface 131a of the exterior member 130 on which the electric wire 12 is disposed is directed to the rod member 70, but this is not essential, and the other main surface 131b is rod-shaped. It may be directed to the member 70 side.

  FIG. 9 is a schematic perspective view showing another modified example 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 slit 32 is not provided in the exterior member 230.

  As described above, even when the slit 32 is not provided in the exterior member 230, the partial region of the exterior member 230 can be rounded and the other partial region can be kept flat.

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

  Also, although the protective sheet has been described as having abrasion resistance, this is not essential. It is also conceivable that the protective sheet has penetration resistance. In this case, the protective sheet only needs to have the penetration resistance required in the use environment of the vehicle, and the needle 80 used when sewing the electric wire 12 to the protective sheet is inserted into the protective sheet with a greater penetration force. It should be done. Moreover, in embodiment, although the exterior member 30 demonstrated as what is a protection sheet, this is not essential. The exterior member 30 may be a soundproof sheet, a shield member, a heat dissipation member, or may function as a tension member.

  Moreover, although the electric wire 12 was demonstrated as what is sewn by a thread 40 one by one so far, this is not essential. A plurality of electric wires 12 may be sewed together by sewing thread 40. In this case, the plurality of electric wires 12 may be integrated by an adhesive tape or the like. Alternatively, a cable may be employed that includes a plurality of wires 12 and a sheath covering the periphery of the plurality of wires 12.

  Moreover, although it demonstrated as what uses the pressure welding connector 20 as the connector 20 until now, this is not essential. For example, the crimp terminal crimped to the end of the wire 12 may be accommodated.

  In addition, each structure demonstrated by said each embodiment and each modification can be combined suitably, as long as there is no contradiction mutually. 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 mentioned above, although this invention was explained in detail, the above-mentioned explanation is illustration in all the aspects, and this invention is not limited to it. It is understood that countless variations not illustrated are conceivable without departing from the scope of the present invention.
