  By the way, in recent years when compactness of vehicles and the like is required, it has become an important issue to route the wire harness by efficiently using the space. However, the wire harness is a bundle of a plurality of electric wires and has a substantially circular cross section. For this reason, even if there is a vacant space, scenes in which the wire harness cannot be routed there have occurred in various places such as vehicles. For example, even if a flat empty space exists, the wire harness cannot be routed there unless the narrow direction of the space is larger than the diameter size of the wire harness, and the space is considered a dead space. turn into.

<1. Overall Configuration of Wire Bundle with Covering Member>
A wire bundle with a covering member according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3 and FIGS. 4 to 6. 1 to 3 illustrate a wire bundle 1a with a covering member having a triangular cross section, and FIGS. 4 to 6 illustrate a wire bundle 1b with a covering member having a hexagonal cross section. 1 to 3 are a schematic perspective view of a wire bundle 1a with a covering member having a triangular cross section, a cross-sectional view (a cross-sectional view in a plane substantially orthogonal to the extending direction of the wire bundle 20), a vehicle interior FIG. 4 to FIG. 6 are schematic perspective views and sectional views (in the extending direction of the wire bundle 20) of the wire bundle 1 b with a covering member having a hexagonal cross section. A sectional view in a plane substantially orthogonal to the above) and a state diagram arranged in the vehicle are shown. Each of the wire bundles 1a, 1b with a covering member has the same configuration except that its cross-sectional shape is different. Hereinafter, the wire bundles with a covering member 1 will be collectively referred to as the case where they are not distinguished from each other.

  The electric wire bundle 1 with a covering member includes an electric wire bundle 20 in which a plurality of electric wires 2 are bundled. As the electric wire 2, what constitutes a wire harness for interconnecting various electric devices in a vehicle or the like is assumed. In the figure, a shape (hereinafter simply referred to as “the cross-sectional shape of the wire bundle 20”) S20 in which the wire bundle 20 is bundled on a surface substantially orthogonal to the extending direction of the wire bundle 20 is a virtual line (dashed line). ).

  Moreover, the wire bundle 1 with a covering member includes a covering member 3 that covers the wire bundle 20. The covering member 3 is a non-circular shape that matches a wiring target location (location where the covering member-attached wire bundle 1 is routed) by being hot-pressed with the non-woven member covering the wire bundle 20. The electric wire bundle 20 is formed in a cross-sectional shape, and is bundled into a shape along the non-circular cross-sectional shape. That is, the covering member 3 functions as a cross-sectional shape restricting member that restricts the electric wire bundle 20 so that the cross-sectional shape S20 thereof is non-circular, and the electric wire bundle 20 in the electric wire bundle with covering member 1 has its cross-sectional shape. S20 is bundled and hardened in a state where it is maintained in a non-circular shape (specifically, a shape along a non-circular shape that matches the routing target location).

  The portion covered by the covering member 3 in the wire bundle 20 is protected by the covering member 3 so that contact with other portions is suppressed. Therefore, in the state where the wire bundle with covering member 1 is routed in the vehicle body, a situation in which the wire bundle 20 is damaged due to contact with the vehicle body panel or the like and noise is avoided. That is, the covering member 3 also functions as a protective member that protects the wire bundle 20.

  Hereinafter, the covering member 3 will be described more specifically.

<2. Covering member 3>
<2-1. Forming Form of Covering Member 3>
The covering member 3 can be formed by hot pressing a non-woven member (for example, non-woven fabric), for example, in a state of covering a part in the extending direction (longitudinal direction) of the wire bundle 20.

  Here, as the non-woven member, a non-woven member that can be hardened through a heating process can be used. As such a non-woven member, a material including a basic fiber and an adhesive resin (also called a binder) intertwined with the basic fiber can be used. The adhesive resin is a resin having a melting point (for example, 110 ° C. to 115 ° C.) lower than the melting point of the basic fiber. When the nonwoven member is heated to a processing temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin, the adhesive resin melts and soaks between the basic fibers. Thereafter, when the nonwoven member has a temperature lower than the melting point of the adhesive resin, the adhesive resin is solidified in a state where the basic fibers are bonded to each other. Thereby, the nonwoven member becomes harder than the state before heating, and is maintained in the molded shape at the time of heating.

  However, the basic fiber may be any fiber that can maintain the fiber state at the melting point of the adhesive resin, and various fibers can be used in addition to the resin fiber. As the adhesive resin, thermoplastic resin fibers having a melting point lower than that of the basic fiber can be used. The adhesive resin may be granular or fibrous. Alternatively, an adhesive resin layer may be formed on the outer periphery of the core fiber to form a binder fiber, which may be entangled with the basic fiber. As the core fiber in this case, the same material as the basic fiber can be used.

  Examples of the combination of the basic fiber and the adhesive resin include an example in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the adhesive resin is a copolymer resin of PET and PEI (polyethylene isophthalate). In this case, the melting point of the basic fiber is approximately 250 ° C., and the melting point of the adhesive resin is 110 ° C. to 150 ° C. For this reason, when the nonwoven member is heated to a temperature of 110 ° C. to 250 ° C., the adhesive resin is melted and soaked between the basic fibers that keep the fiber shape without melting. And when a nonwoven member becomes temperature lower than melting | fusing point of adhesive resin, adhesive resin solidifies in the state which couple | bonded basic fibers, a nonwoven member becomes hard and maintains the shaping | molding shape at the time of a heating.

  Hot pressing refers to molding a nonwoven member by sandwiching a nonwoven member that is an object to be processed between molds and applying pressure to the mold in a heated state.

<2-2. Cross-sectional shape of covering member 3>
As described above, the cross-sectional shape of the covering member 3 (the shape on the surface substantially orthogonal to the extending direction of the covering member-attached electric wire bundle 1) is formed in a non-circular shape that matches the wiring target location. The cross-sectional shape of the covering member 3 will be specifically described with reference to FIGS.

<Wire bundle 1a with covering member>
FIG. 3 schematically shows the state of the lower portion of the door in the vehicle. As shown here, a side sill portion 501 that supports a side opening of the vehicle body is provided in the lower portion of the door. A scuff plate 502 is provided on the side sill portion 501 to protect the side sill portion 501 from being stepped on by a person getting on and off the vehicle. On the other hand, the floor carpet 503 laid in the passenger compartment extends from the passenger compartment, rises along the side sill portion 501 at the side end, covers the side sill portion 501, and covers the upper surface of the side sill portion 501 and the scuff plate 502. It is inserted and fixed between the lower surface. Here, a gap space V <b> 1 is formed between the portion raised along the side sill portion 501 in the floor carpet 503 and the side sill portion 501. For example, as illustrated in FIG. 3, a gap space V <b> 1 is formed in which a cross-sectional shape in a direction substantially orthogonal to the extending direction of the side sill portion 501 is a substantially triangular shape.

  The wire bundle with covering member 1a is routed in the gap space V1 along the extending direction of the side sill portion 501. In this case, the cross-section of the covering member 3a has a shape that matches the gap space V1 that is the location to be routed, specifically, for example, the cross-sectional shape of the gap space V1 (approximately the routing direction of the wire bundle 1 with the covering member). It is substantially similar to the cross-sectional shape in the orthogonal direction) and is slightly smaller than the cross-section. As illustrated in FIG. 3, when the cross-sectional shape of the gap space V1 is substantially triangular, the cross-section of the covering member 3a is, for example, a triangular shape that is slightly smaller than the cross-section of the gap space V1.

  In the case of the wire bundle 9 with a protective member in which the wire bundle 20 is inserted into a cylindrical protector, if the wire bundle 20 is to be routed in the gap space V1, the floor carpet 503 is swelled as shown in FIG. This is not preferable in terms of design. In order to avoid this, when the wire bundle 9 with a protective member is routed on the side sill portion 501, it is necessary to raise the scuff plate 502 so as to cover it, and the height of the sill under the door of the vehicle is high. It is difficult to achieve a vehicle layout that is easy to move up and down.

  On the other hand, since the cross-sectional shape of the wire bundle with covering member 1a is a triangular shape that matches the location to be routed, as shown in FIG. The shape follows the carpet 503, and the floor carpet 503 does not bulge. For this reason, it is not obstructed to route the wire bundle 1a with the covering member in the gap space V1 in terms of aesthetics. Therefore, the wire bundle 20 can be routed in the gap space V1 that cannot be routed in a state where the wire bundle 20 is bundled in a circular cross section, and the gap space V1 does not become a dead space. That is, the wire bundle 1a with a covering member can be routed using space efficiently. Moreover, since there is no need to route the electric wire bundle 20 on the side sill portion 501, a vehicle layout that is easy to move up and down can be realized.

<Wire bundle 1b with covering member>
FIG. 6 schematically shows the state of the upper portion of the door in the vehicle. As shown here, a side rail portion 505 disposed on the side of a vehicle roof panel 504 is provided in the upper portion of the door. A trim (liner in the passenger compartment) 506 is attached to the side rail portion 505. A side end portion of the trim 506 is attached to a liner 507 disposed on the lower side of the roof panel 504. Here, a gap space V <b> 2 is formed between the trim 506 and the side rail portion 505. For example, as illustrated in FIG. 6, a gap space V <b> 2 having a flat cross-sectional shape in a direction substantially orthogonal to the extending direction of the side rail portion 505 is formed.

  The wire bundle with covering member 1b is routed in the gap space V2 along the extending direction of the side rail portion 505. In this case, the cross-section of the covering member 3b has a shape that matches the gap space V2 that is the location to be routed, specifically, for example, the cross-sectional shape of the gap space V2 (approximately the routing direction of the wire bundle 1 with the covering member). The cross-sectional shape in the orthogonal direction) is substantially the same at one or more inner angles. As illustrated in FIG. 6, when the cross-sectional shape of the gap space V <b> 2 is an irregular flat shape, for example, the cross-section of the covering member 3 b is substantially equal to the angle of bending from the side rail portion 505 to the roof panel 504. It is a flat hexagon with an interior angle that matches. In this case, the wire bundle 1b with a covering member can be arranged along the bend from the side rail portion 505 to the roof panel 504.

  In the case of the wire bundle 9 with a protective member in which the wire bundle 20 is inserted through a cylindrical protector, as shown in FIG. 11, unless the narrow direction of the gap space V2 is larger than the diameter size of the wire bundle 9 with a protective member, If the wire bundle 9 with a protective member cannot be routed in the gap space V2, and the diameter of the wire bundle 9 with a protective member is smaller than the diameter, the gap space V2 becomes a dead space. In this case, since the electric wire bundle 9 with the protective member has to be routed, for example, in the vehicle interior, the vehicle interior becomes narrow and an efficient interior layout cannot be realized. Moreover, when the wire bundle 9 with a protective member is routed in the vehicle interior, it is necessary to further provide a cover 91 for blinding the wire bundle 9 with the protective member, which is disadvantageous in manufacturing cost.

  On the other hand, since the cross-sectional shape of the wire bundle with covering member 1b is a flat hexagonal shape that matches the location to be routed, the wire bundle 20 is bundled in a circular cross section as shown in FIG. It is possible to route in the flat gap space V2 that could not be routed in the state. Therefore, the gap space V2 does not become a dead space. That is, the wire bundle 1b with a covering member can be routed using space efficiently. Moreover, since the wire bundle with covering member 1b is not exposed in the vehicle interior, it is not necessary to provide a cover or the like. Therefore, the manufacturing cost is also advantageous.

<3. Manufacturing method of wire bundle 1 with covering member>
The method for manufacturing the wire bundle 1 with the covering member will be specifically described.

<3-1. Hot press mold>
First, a configuration example of a hot pressing mold used for manufacturing the electric wire bundle 1 with a covering member will be described with reference to FIG. FIG. 7 is a schematic perspective view showing a configuration example of the hot press mold 8. The shape of the hot pressing mold 8 used for manufacturing the wire bundle with covering member 1 is determined according to the shape of the wire bundle with covering member 1 to be manufactured. FIG. 7 illustrates a hot press mold 8 used to manufacture the wire bundle with covering member 1a having a triangular cross section.

  The hot press mold 8 includes a lower mold 81, a lower mold holder 82, and an upper mold 83.

  The lower die 81 is a long member formed of a metal or the like having excellent thermal conductivity, and a lower die surface 810 is formed on one main surface (upper surface) thereof. The lower mold surface 810 is generally formed in a substantially rectangular groove shape that is open at the top and both ends.

  The lower mold holder 82 is formed of a metal plate or the like having excellent thermal conductivity, and is formed in the same uneven shape as the lower mold surface 810. The lower mold holder 82 is detachably placed on the lower mold surface 810, and functions as a part that forms a lower part when hot pressing the nonwoven member. The lower mold holder 82 is used to easily perform the work of setting the non-woven member and the wire bundle 20 and the work of taking out the wire bundle 1 with the covering member after hot pressing from the lower mold 81. The lower mold holder 82 is not essential and may be omitted. When the lower mold holder 82 is used, the upper surface of the lower mold holder 82 functions as a mold surface that directly shapes the shape of the wire bundle 1 with the covering member. For this reason, the upper surface of the lower mold holder 82 is also referred to as the lower mold surface 820.

  The upper die 83 is a long member formed of a metal or the like having excellent thermal conductivity, and a protruding portion 831 whose tip is cut obliquely is formed on one main surface (lower surface) thereof. The obliquely cut surface of the protrusion 831 functions as the upper mold surface 830. The upper mold surface 830 is formed in a rectangular shape in plan view that can close the upper opening of the lower mold surface 810 (lower mold surface 820), and is disposed in the lower mold surface 810 (lower mold surface 820). Thus, the wire bundle 1a with a covering member having a triangular cross section is formed between the upper mold surface 830 and the lower mold surface 810 (lower mold surface 820).

  The lower mold 81 and the upper mold 83 are provided with a heater 84 as a heating device (see FIG. 8 and the like). The heater 84 heats the lower mold surface 810 (lower mold surface 820) and the upper mold surface 830 to a temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin. For example, the heater 84 may be embedded in the lower mold 81 and the upper mold 83, or may be attached to the outer surface of the lower mold 81 and the upper mold 83 in a manner capable of transferring heat. It may be.

<3-2. Production of wire bundle 1 with covering member>
Next, a method for manufacturing the wire bundle 1 with a covering member using the hot press mold 8 will be described with reference to FIGS.

  It is assumed that the position of the covering target portion in the wire bundle 20 is specified before the following steps are performed. The position of the covering target portion is shown, for example, on an assembly drawing board used for assembling the electric wire bundle 20. In the assembly process of the electric wire bundle 20, the electric wire bundle 20 is placed by a jig erected on the assembly drawing board. In the state where it is wired on the wiring board in the received state and has a pre-designed branch shape, it is specified which position in the wire bundle 20 is to be covered based on the assembly drawing board can do.

  First, the wire bundle 20 wrapped by the non-woven member 100 is disposed in the lower mold surface 810 (lower mold surface 820) of the lower mold 81 (FIG. 8). More specifically, one non-woven member 100 is disposed along the inner peripheral bottom surface and both side surfaces of the lower mold surface 810 (lower mold surface 820). Then, the covering target region of the wire bundle 20 is disposed in the non-woven member 100. At this time, the cross-sectional shape of the wire bundle 20 is, for example, a substantially circular shape. The non-woven member 100 is formed in a rectangular shape having a width capable of enclosing the electric wire bundle 20, and both sides of the non-woven member 100 are on the upper opening side of the lower mold surface 810 (lower mold surface 820). Are in mutual contact. The lower mold holder 82 may be set on the lower mold 81 after the non-woven member 100 and the wire bundle 20 are disposed in the lower mold holder 82.

  Subsequently, while the lower die 81 and the upper die 83 are heated, the upper die surface 830 of the upper die 83 is moved close to the lower die surface 810 (lower die surface 820), and pressure is applied therebetween. Then, the non-woven member 100 is compressed while covering the wire bundle 20. Here, since the space formed between the upper mold surface 830 and the lower mold surface 810 (lower mold surface 820) has a triangular cross section, the electric wire bundle 20 covered with the non-woven member 100 has a cross section thereof. The shape S20 is gradually deformed from a substantially circular shape, and finally, the shape S20 is collected in a shape bundled into a shape along a triangular cross-sectional shape. That is, the non-woven member 100 is compressed while deforming the cross-sectional shape S20 of the wire bundle 20 from a substantially circular shape to a substantially triangular shape while covering the wire bundle 20 (FIG. 9). Thereby, the wire bundle 1a with a covering member having a triangular cross section is formed. The non-woven member 100 is compressed at the upper mold surface 830 side of the wire bundle 20 and both side edges of the non-woven member 100 are pressure bonded.

  Thereafter, when the lower die 81 and the upper die 83 are moved away from each other and the hot-pressed wire bundle with covering member 1a is taken out from both, the covering member-attached wire bundle 1a is obtained. Cooling after hot pressing may be performed in a state existing between the lower mold 81 and the upper mold 83 or may be performed in a state of being taken out from between them. In the latter case, the wire bundle with covering member 1a may be cooled with the lower mold holder 82 removed from the lower mold 81.

<4. Effect>
According to the above embodiment, since the covering member 3 bundles the wire bundle 20 in a shape along a non-circular cross-sectional shape that matches the location to be routed, the cross section of the wire bundle 20 remains circular. Then, the electric wire bundle 20 can be routed in a space that could not be routed.

<5. Modification>
In the above embodiment, the wire bundle with covering member 1a having a triangular cross section and the hexagonal covering member electric wire bundle 1b having a flat cross section are exemplified, but the shape of the wire bundle with covering member 1 is as follows. It can be freely defined according to the cross-sectional shape of the location to be routed, for example, various polygonal shapes, oval shapes (shapes in which two semicircles are connected by a straight line) shapes, elliptical shapes, semicircular shapes, etc. be able to.

  Moreover, in said embodiment, although the cross section showed the triangle-shaped electric wire bundle 1a with a covering member, the cross section of the electric wire bundle 1a with a covering member may be a rounded triangular shape. The same applies to the hexagonal wire bundle with covering member 1b having a flat cross section.

  Moreover, as above-mentioned, the coating | coated member 3 is formed in the shape suitable for the wiring object location, but the aspect which prescribes | regulates the shape suitable for the wiring object location is not restricted to what was illustrated above. For example, the cross-section of the covering member 3a is substantially similar to the shape obtained by simplifying the cross-sectional shape of the gap space (the cross-sectional shape in the direction substantially perpendicular to the wiring direction of the covering member-attached electric wire bundle 1). It is good also as a shape one size smaller than the said cross section. Specifically, for example, in the case where the cross-sectional shape of the gap space serving as the routing target portion is a flat hexagonal shape, the cross-section of the covering member 3 may be an oval shape.

  Moreover, in said embodiment, the electric wire bundle 1 with a covering member may be formed by hot-pressing the non-woven member in a state where the electric wire bundle 20 is sandwiched between two non-woven members.

  Moreover, in said embodiment, although the electric wire bundle 1 with a covering member was made into the shape extended linearly, and the electric wire bundle 20 was set as the structure maintained linearly, the electric wire bundle 1 with a covering member is not necessarily required. It does not have to be linear, and may be bent in an arc or at an angle, and the wire bundle 20 may be route-regulated in a form bent in an arc or an angle.

  In the hot press mold 8 in the above embodiment, the wire bundle 1 with a covering member is formed by a combination of a concave mold and a convex mold, but this is not always necessary. It may be a combination.
