  However, according to the technique disclosed in Patent Document 1, since it is necessary to mold the bending angle regulating plate for the wire harness with an injection mold, the manufacturing cost increases due to equipment costs and the like.

  Moreover, in patent document 2, a protection member is formed in the shape corresponding to the routing route where a wire harness is routed in order to maintain the route of a wire harness main body. For this reason, the metal mold | die used for the hot press of a nonwoven material is formed in the shape corresponding to the wiring path | route of a wire harness. For this reason, it is necessary to manufacture a metal mold | die for every application location from which a routing route differs, and versatility is scarce.

  Accordingly, an object of the present invention is to make it possible to manufacture a route regulating device capable of regulating a route with versatility even in differently shaped routing route portions without injection molding.

  In order to solve the above-described problem, a first aspect is a path regulating member that regulates a path of a wire harness body including at least one electric wire, and hot-presses a non-woven material to extend the wire harness body. A cut is formed in a side portion of the container formed in a shape that can be accommodated along the direction in a direction intersecting the extending direction of the container, and both side portions sandwiching the cut are at a constant angle. The container is fixed in a bent form.

  A 2nd aspect is a path | route control member which concerns on a 1st aspect, Comprising: The said accommodating body is formed so that the cross section orthogonal to the said extension direction may exhibit U shape.

  A 3rd aspect is the path | route control member which concerns on a 1st or 2nd aspect, Comprising: The said container is being fixed by the form which accumulated the both-sides part on both sides of the said notch.

  A 4th aspect is a manufacturing method of the path | route control member which performs path | route control of the wire harness main body containing at least 1 electric wire, Comprising: (a) Hot-pressing a nonwoven material and extending the said wire harness main body Forming a container that can be accommodated along the side, (b) forming a cut in a side portion of the container in a direction intersecting the extending direction of the container, and (c) the cut. And fixing the container in a bent form so that both sandwiched portions are at a constant angle.

The side is formed with a cut in a direction crossing the extending direction of the container, and the container is fixed in a bent form so that both side portions sandwiching the cut have a constant angle, A path regulating member that covers at least a part of the outer periphery of the wire harness body.

  According to the path regulating member according to the first aspect, because it is formed by forming a cut in the container formed by hot pressing the nonwoven material, and fixing the container in a form bent at a certain angle, A mold used for hot pressing of a non-woven material can have a common shape even in different routing paths. Thereby, it is possible to regulate the route with versatility even in the routing route portions having different shapes. Moreover, since the operation | work which hot-presses the said nonwoven material can be performed with a simple metal mold | die, it can manufacture even if it does not carry out injection molding of the path | route control member.

  According to the path | route control member which concerns on a 2nd aspect, since the accommodating body is formed in cross-sectional view U shape, formation of the accommodating body by hot press is easy.

  According to the path | route control member which concerns on a 3rd aspect, since the accommodating body is being fixed with the form which accumulated the both-sides part which pinched | interposed the notch | incision, a bending form can be maintained more reliably.

  According to the method for manufacturing a path regulating member according to the fourth aspect, a hot press is used to form a cut in a container formed by hot pressing a non-woven material and fix the container in a form bent at a certain angle. It is possible to make the mold used for the same shape even in different routing paths. Thereby, it is possible to regulate the route with versatility even in the routing route portions having different shapes. Moreover, since the operation | work which hot-presses the said nonwoven material can be performed with a simple metal mold | die, it can manufacture even if it does not carry out injection molding of the path | route control member.

  Hereinafter, the path regulating member 20, the manufacturing method of the path regulating member 20, and the wire harness 10 according to the embodiment will be described (see FIG. 1). The wire harness 10 is a wiring material routed in an automobile or the like, and includes a wire harness main body 12 and a path regulating member 20.

  The wire harness body 12 includes at least one electric wire. For example, the wire harness body 12 is configured by bundling a plurality of electric wires. The wire harness body 12 may include an optical fiber cable or the like in addition to the electric wire.

  The route restriction member 20 is a member that protects the wire harness body 12 and maintains the wire harness body 12 along the routing route (that is, restricts the route). The path regulating member 20 covers and protects the wire harness body 12 by covering at least a part of the wire harness body 12. Here, an example in which a part of the wire harness main body 12 in the extending direction is covered and described as route regulation and protection will be described, but the wire harness main body 12 may be entirely covered.

  The path regulating member 20 is manufactured through the following steps. First, the nonwoven material 21 is hot-pressed to form a container 22 that can accommodate the wire harness body 12 along the extending direction (see FIGS. 2 and 3). Next, a cut 26 is formed in a side portion of the container 22 in a direction crossing the extending direction of the container 22 (see FIG. 4). Further, the container 22 is bent (see FIG. 5) so that both side portions sandwiching the cut 26 are at a constant angle, and fixed in a bent form (see FIG. 1).

  Here, the hot press refers to performing a heat treatment and a process of pressing the nonwoven material against a mold to form it into a predetermined shape. The heat treatment and the forming process into a predetermined shape may be performed simultaneously or may be performed separately continuously. For example, the nonwoven material can be heated in a state compressed into a predetermined shape and maintained in a predetermined shape by cooling.

  In addition, as the nonwoven material to be processed, a material that can be at least partially melted or softened and then hardened through a cooling step can be used. As such a nonwoven material, a material containing basic fibers and a binder (also referred to as an adhesive resin) can be used. The binder is a resin having a melting point lower than that of the basic fiber. Then, by heating the nonwoven material to a temperature lower than the melting point of the basic fibers and higher than the melting point of the binder, the binder is melted and soaks between the basic fibers. Thereafter, when the temperature of the nonwoven material is lowered, the binder is solidified. Thereby, a nonwoven material can be maintained in the shaping | molding state at the time of a heating. Moreover, the solidified binder can also join the contact parts of nonwoven materials.

  As the basic fiber of the nonwoven material, it is only necessary to maintain the fiber state at the melting point of the binder, and various fibers such as glass fibers can be used in addition to the resin fibers. Moreover, the thermoplastic resin fiber which has melting | fusing point lower than melting | fusing point of a basic fiber can be used for a binder. For example, as a combination of a basic fiber and a binder, there may be mentioned one in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the binder is a copolymer resin of PET and PEI (polyethylene isophthalate).

  Here, the container 22 is formed in a U shape in a cross-sectional view orthogonal to the extending direction of the wire harness body 12 housed inside by hot pressing the nonwoven material 21 (FIG. 2). (See FIG. 3). That is, the container 22 has a substantially arc-shaped bottom 23 and a pair of side walls 24 extending from both ends of the bottom 23 in a cross-sectional view orthogonal to the extending direction. Here, the container 22 is formed in a shape extending linearly. But the container 22 may be formed in the shape which has a curve part or a bending part. From the viewpoint of increasing versatility, the container 22 is preferably formed in a linear shape.

  Further, the container 22 may be provided with a difference in hardness between the inner peripheral portion and the outer peripheral portion by providing a difference in heating temperature between the inner mold 92 and the outer mold 94 used for hot pressing. Good. For example, if the outer peripheral side portion is softer than the inner peripheral side portion of the container 22, abnormal noise due to contact with the external member of the path regulating member 20 can be suppressed. But a container may form an outer peripheral side part harder than an inner peripheral side part, and does not need to provide the difference of hardness in an inner peripheral side part and an outer peripheral side part. That is, the hardness of the inner peripheral portion and the outer peripheral portion of the container is preferably determined in consideration of the balance between the sound deadening property and the wear property of the container. Of course, the inner peripheral portion and the outer peripheral portion of the container 22 may be finished to the same degree of hardness.

  The difference in hardness between the inner peripheral side portion and the outer peripheral side portion of the container is that the non-woven material has a multi-layer structure, and the melting point of the binder or the binder ratio, etc. on one main surface side and the other main surface side It can also be realized by changing the above.

  Further, here, the cut 26 is formed in a slit shape that intersects the extending direction of the container 22 (see FIG. 4). More specifically, the notch 26 is formed from the pair of side wall portions 24 or from the pair of side wall portions 24 to both ends of the bottom portion 23 so as to leave at least a part of the bottom portion 23 of the container 22.

  FIG. 4 shows an example in which the cuts 26 are formed from the pair of side wall portions 24 to both end portions of the bottom portion 23 along the direction orthogonal to the extending direction of the container 22. However, the cut may be inclined with respect to the direction orthogonal to the extending direction of the container 22 or may be formed only in the pair of side wall portions 24. Moreover, although the notch 26 has shown the example currently formed in the position which opposes (the same position in the extending direction), if it can bend the container 22 on the basis of the part between notches 26, , They may be formed at positions shifted from each other.

  The container 22 is bent (see FIG. 5) and fixed in a bent form (see FIG. 1) so that both side portions sandwiching the cut are at a constant angle. More specifically, it is fixed in a form bent around an axis along the direction connecting the pair of side wall portions 24. Here, the container 22 is fixed in a form in which both side portions sandwiching the cuts 26 in the extending direction are overlapped. That is, both side portions sandwiching the notch 26 overlap the inside and outside of the housing portion 22, and the housing portion 22 is bent by the overlapping region. Here, the angle at which the container 22 is bent may be bent at an angle along the wiring path of the wire harness body 12. Examples of the fixing structure in the bent form of the container 22 include a structure in which both side portions of the cut 26 are overlapped, heat welding, ultrasonic welding, welding using a hot melt agent, staple fixing, tape fixing, and the like. .

  Here, although an example in which a pair of cuts 26 are formed is described, the cuts 26 are formed at a plurality of positions in the extending direction of the container 22 according to the wiring form of the wire harness body 12, and the cuts 26 are formed at a plurality of positions. A bent path regulating member can be formed.

  The wire harness 10 is comprised by arrange | positioning the wire harness main body 12 inside the path | route control member 20 manufactured as mentioned above (refer FIG. 1). That is, the path | route control member 20 is the form which covered at least one part of the outer peripheral part of the wire harness main body 12, and is controlling the hair color and protecting the wire harness main body 12.

  The path regulating member 20 may be fixed in a form in which the opening between the front end portions of the pair of side wall portions 24 is closed in a state where the wire harness body 12 is disposed on the inside (see FIG. 6). That is, it fixes in the form which faced | matched the front-end | tip parts of a pair of side wall part 24, or was piled up inside and outside. Thereby, the wire harness main body 12 is protected over the entire circumference, and the path is restricted to the bent form of the path restricting member 20. Examples of the fixing structure include a structure in which both side portions of the cut 26 are welded, stapled, and taped using a thermal welding, an ultrasonic welding, and a hot melt agent. In FIG. 6, the adhesive tape 80 is wound around the outer periphery of the path | route control member 20, and the example which carried out the tape stop is shown.

  The work of fixing the opening of the path regulating member 20 in the closed form may be performed simultaneously with the work of fixing the container 22 in the bent form with the wire harness main body 12 disposed inside the container 22. . For example, when adopting tape winding as a fixing method, the tape is spirally formed on the outer periphery of the container 22 while the container 22 is bent and the opening between the distal ends of the pair of side walls 24 is held closed. Wrap around.

<Effect>
According to the route regulating member 20, the manufacturing method of the route regulating member 20, and the wire harness 10 according to the above embodiment, the incision 26 is formed in the housing 22 formed by hot pressing the nonwoven material 21, and the housing 22 is fixed. The container 22 formed by hot pressing the non-woven material 21 is made common, and a plurality of different arrangements are made depending on the position of the cut 26 and the setting of the bending angle. The path regulating member 20 having a form corresponding to the cable path can be formed. That is, the mold used for the hot pressing of the nonwoven material 21 can have a common shape such as a straight line shape even in different routing paths. Thereby, a design change can be easily performed also in the routing route part of a different shape, and the wire harness main body 12 can be route-regulated with versatility.

  Moreover, the said path | route control member 20 can be manufactured by hot-pressing a nonwoven material with a simple mold, without using an injection mold, and can manufacture a path | route control member with simple manufacturing equipment.

  In addition, since hot press molds generally become expensive when the depth of the mold surface increases, path control members that extend three-dimensionally are formed by hot pressing, so that path control is required in terms of cost. The shape of the member may be restricted. Moreover, depending on the equipment of the hot press, a mold having a high height (a mold surface is deep) may not be used due to a restriction on the height of the mold. In this respect, the path regulating member 20 can form a container 22 formed by hot pressing the non-woven material 21 into a two-dimensionally extending shape such as a linear shape. It is possible to reduce the equipment cost for the mold.

  Moreover, since the path | route control member 20 is formed by hot-pressing a nonwoven material, it can be made flexible to some extent, maintaining abrasion resistance compared with a resin product. Thereby, while suppressing the generation of sound due to contact between the path regulating member 20 and peripheral parts or contact between the path regulating member 20 and the internal wire harness 12 (silence), the path regulating member excellent in wear resistance. 20 can be provided.

  In addition, since the notch 26 is inserted into the container 22 formed by hot pressing the nonwoven material 21 and bent at the position of the notch 26, the inner due to the temperature difference between the inner mold and the outer mold used for the hot press or the like. The difference in hardness between the peripheral portion and the outer peripheral portion can be set, and depending on the properties required according to the location of placement, etc., in the inner peripheral portion or the outer peripheral portion, the wear resistance or It is possible to impart a property excellent in silencing properties. Further, it is possible to add a notch 26 after forming the path regulating member 20 and add a bent shape.

  Moreover, since the container 22 is formed in a U shape in a sectional view, it is easy to form the container 22 by hot pressing.

  Moreover, when the cut 26 is formed in a slit shape, the cut 26 can be easily formed, and the operation can be simplified.

  Moreover, since the container 22 is fixed in a form in which both side portions sandwiching the notch 26 are overlapped, it is possible to suppress the exposure of the wire harness body 12 disposed inside the path regulating member 20 to the outside. it can. Furthermore, when both are fixed in the region where both side portions of the cut 26 overlap, the bent form can be maintained more easily and reliably than in the case where both are fixed together.

<Modification>
So far, the example in which the slit-like cut 26 is formed in the container 22 has been described, but the present invention is not limited to this. For example, a wedge-shaped cut 126 that becomes narrower as it approaches the bottom 23 from the tip of the pair of side walls 24 may be formed (see FIG. 7). In this case, both side portions sandwiching the notch 26 may be abutted and fixed (see FIG. 8), or the both side portions may be overlapped and fixed inside and outside. In addition, when fixing with the form which faced the both sides which pinched | interposed the notch 126, it is good for the notch 126 to set the length dimension of the edge parts to face | match to substantially the same. The fixing can be performed by tape fixing, fixing with an adhesive, or the like.

  According to the form in which the cut 126 having this shape is formed, the operation of fixing the container 22 in the bent form can be performed more easily.

  Further, the example in which the cuts 26 are formed on both sides of the container 22 has been described so far, but the present invention is not limited to this. That is, a cut may be formed only on one side of the container 22 and the container 22 may be fixed in a bent form around an axis along the extending direction of the pair of side wall parts 24.

  Moreover, although the example which hot-presses the nonwoven material 21 and forms the container 22 of a cross-sectional view U shape has been demonstrated, it is not restricted to this. For example, a container having a square groove shape or a cylindrical shape (polygonal cylindrical shape, cylindrical shape, elliptical cylindrical shape, etc.) having a bottom formed in a planar shape may be formed. When forming the cylindrical container 222 as shown in FIG. 9, a wedge-shaped cut 226 is formed in a part of the container 222 in the circumferential direction (see FIG. 10), and the container 222 may be bent and fixed (FIG. 11). reference). More specifically, the container 222 is bent at a portion between the cuts 226 in the circumferential direction. The wire harness body 12 may be inserted inside the housing body 222 before the bending operation of the housing body 222, or may be inserted inside the housing body 222 after the bending operation.

  According to the form in which the cylindrical container 222 is formed, the entire circumference of the wire harness body 12 can be covered and protected more easily.

  As mentioned above, although this invention was demonstrated in detail, above-described description is an illustration in all the phases, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
