Description

Technical Field

[0001] This disclosure relates to a flat bundle component and a wire harness. Background Technology

[0002] To ensure sufficient space in vehicles, existing wiring harnesses need to have a reduced height.

[0003] As an example, a wire harness is proposed in which wires are flatly bundled into multiple layers by arranging wires side by side on a planar sheet, arranging another sheet on top of it, and then arranging wires side by side again (see, for example, JP2019-204745A).

[0004] A wire harness is also proposed in which wires are arranged side by side in one or two layers on a sheet, and at least a portion of the arranged wires are covered from above and below by folding the sheet (see, for example, JP2021-157927A).

[0005] However, the sheet materials described in JP2019-204745A and JP2021-157927A have poor processability as flat bundle components for bundling wire harnesses into a flat shape.

[0006] For example, in the technology described in JP2019-204745A, the placement of sheets, the arrangement of wires, and the placement of sheets are performed sequentially to obtain a wire harness in which wires are arranged flatly on one layer sandwiched from above and below to reduce height. However, when wires are arranged in two or more layers, one or more additional wire arrangement and sheet placement steps are required, resulting in a large number of steps. Therefore, it cannot be said that the wire harness described in JP2019-204745A can be manufactured with good processability.

[0007] Similarly, in the technology described in JP2021-157927A, the placement of the sheet, the placement of the wires, and the operator's folding operation in the proper position are essential. Therefore, when the operator folds in the wrong position, wires that should be clamped from above and below may not be clamped, and wires that should not be clamped from above and below may be clamped. Therefore, the operator needs to pay attention to folding in the correct position, and it cannot be said that the wire harness described in JP2021-157927A can be manufactured with good workability. Summary of the Invention

[0008] This disclosure provides a flat bundled component and wire harness that can further improve manufacturability.

[0009] According to one illustrative aspect of this disclosure, a flat bundle member having a sheet-like structure and bundling wires into a flat shape includes: a plurality of foldable structures configured to fold the sheet into a corrugated shape; and a wire arrangement portion that, when folded into the corrugated shape by the plurality of foldable structures, becomes a flat face and the wires are arranged thereon in a flat shape.

[0010] According to another illustrative aspect of this disclosure, a wire harness includes: a flat bundle member folded into a corrugated shape as described above; and wires fixed to the wire arrangement portion of the flat bundle member. Protective portions on both ends of the flat bundle member are connected to each other. Attached Figure Description

[0022] In the following description, this disclosure will be described with reference to preferred embodiments. This disclosure is not limited to the embodiments described below, and may be appropriately modified without departing from the spirit of this disclosure. In the embodiments described below, some illustrations and descriptions of certain configurations are omitted, and it is understood that well-known or familiar techniques are appropriately applied to omit details of the omissions without contradicting the following description.

[0023] Figure 1 This is a side view showing a schematic construction of the wire harness and flat bundle member according to the first embodiment. Figure 1 The wire harness WH shown is mounted on, for example, the wall WA of a vehicle, and is used to bundle multiple wires W after they have been arranged in a flat, side-by-side configuration in multiple layers. The wire harness WH includes multiple wires W, a flat bundling component 10, and connecting and securing components 20.

[0024] exist Figure 1 In the example shown, multiple wires W are arranged in a flat shape, i.e., along the wall WA. The multiple wires W can be power lines, signal lines, or combinations thereof. It is assumed that the wires W have any size using polyvinyl chloride (PVC) and polyolefins, but are not limited to this, and can be stranded wires, coaxial cables, or optical fibers.

[0025] The flat bundle member 10 has a sheet-like shape and is folded into a corrugated shape by being folded in at least two locations to bundle the wires W into a flat shape. Figure 2 It indicates that it is in the unfolded state. Figure 1 A side view of a portion of the construction of the wire harness WH shown.

[0026] like Figure 2As shown, the flat bundled component 10 includes multiple foldable structures 11, a wire arrangement section 12, and a protective section 13. The multiple foldable structures 11 facilitate the folding of the corrugated sheet. That is, compared to a portion without foldable structures 11 (e.g., the position indicated by reference numeral X), the foldable structures 11 can be structures that reduce the force required for folding. In the first embodiment, the foldable structures 11 are achieved by creases 11a formed by pre-folding into a mountain-shaped fold or a valley-shaped fold for folding into a corrugated shape. Here, mountain-shaped folds and valley-shaped folds can be referred to as convex folds and concave folds, respectively.

[0027] The wire arrangement section 12 is the portion where, when the flat bundle member 10 is folded into a corrugated shape by the foldable structure 11, it becomes a flat surface and the wires W are arranged flat thereon. In the first embodiment, the foldable structure 11 is provided in three locations, and the portion sandwiched by the foldable structure 11 is the wire arrangement section 12. In the first embodiment, multiple wire arrangement sections 12 have the same shape and area, and may also have different shapes or areas, or different shapes and areas.

[0028] The protective part 13 is connected to the outermost wire arrangement part 12 when the flat bundle member 10 is folded by the foldable structure 11, and protects the wire W. Figure 1 As shown, when installed in a vehicle, the protective part 13 is located at the uppermost or lowermost end. Therefore, in the first embodiment, the protective part 13 protects the wire W from both above and below.

[0029] In the first embodiment, the flat bundle member 10 includes protective portions 13 at both ends. However, this disclosure is not limited thereto. The flat bundle member 10 may include a protective portion 13 only on one side, or when the flat bundle member 10 itself does not require protection, for example when the flat bundle member 10 is covered by another external component, the protective portion 13 may not be included.

[0030] Figure 1 The connecting and securing components 20 shown connect the protective portions 13 on both ends of the flat bundled component 10 to each other. In the first embodiment, the connecting and securing components 20 are implemented by a resin tape having an adhesive surface on one side and resin on the other side. The resin tape can be a relatively easy-to-peel Velcro strap (registered trademark), etc. The connecting and securing components 20 are not limited to resin tape; they can also be pin components made of metal or resin that are installed by a nailing machine, or they can be adhesives between the contact portions of the protective portions 13. The adhesive is assumed to be one or more combinations of natural rubber, styrene-isoprene-styrene block copolymer, and acrylic resin, but is not particularly limited thereto.

[0031] Figures 3A to 3D It is shown Figure 1 and Figure 2 An enlarged cross-sectional view showing details of the flattened clustering member 10. The flattened clustering member 10 can have various layer structures, and... Figures 3A to 3D The examples shown have one to three-layer structures.

[0032] First, such as Figure 3A As shown, the flat bundle member 10 has a single-layer structure including a substrate layer 10a. The substrate layer 10a can be a film such as PVC, polyolefin, or polyethylene terephthalate (PET). The substrate layer 10a can also be a film such as fluorine, polyimide, silicone, cellophane, or nylon, or it can be a mesh material or fabric. When the flat bundle member 10 has a single-layer structure including the substrate layer 10a, multiple wires W are fixed to the flat bundle member 10 (substrate layer 10a) by applying pressure through methods such as thermal welding, ultrasonic welding, bonding, and clamps.

[0033] like Figure 3B As shown, the flat bundle member 10 can have a two-layer structure including a substrate layer 10a and a protective layer 10b. Here, the substrate layer 10a and the protective layer 10b can be the same component or different components. When the substrate layer 10a and the protective layer 10b are different components, the protective layer 10b is preferably made of a component with higher wear resistance and impact resistance than the substrate layer 10a. As described above, multiple wires W are fixed to the flat bundle member 10 (substrate layer 10a) by means of thermal welding, ultrasonic welding, bonding, and applying pressure by means of clamps, etc.

[0034] like Figure 3C As shown, the flat bundle member 10 can have a two-layer structure including a protective layer 10b and an adhesive layer 10c. Because the flat bundle member 10 includes the adhesive layer 10c, multiple wires W can be fixed to the wire arrangement section 12 (see...). Figure 2 It can be applied without the need for hot welding, etc.

[0035] like Figure 3D As shown, the flat bundle member 10 can have a three-layer structure including a substrate layer 10a, an adhesive layer 10c, and a base coat 10d disposed therebetween. Similar to the above, since the flat bundle member 10 includes the adhesive layer 10c, multiple wires W can be fixed to the wire arrangement section 12 without the need for thermal welding. Because the flat bundle member 10 includes the base coat 10d, substances in the adhesive layer 10c can be prevented from moving to the substrate layer 10a, making it difficult to apply adhesive force to the adhesive layer 10c and preventing deterioration of the substrate layer 10a. Because the flat bundle member 10 includes the base coat 10d, sufficient adhesion can be obtained even when the compatibility between the substrate layer 10a and the adhesive layer 10c is poor.

[0036] The flat bundle member 10 is not limited to the shape described above. For example, in the flat bundle member 10, if possible, the above-described members can be combined with each other so that the wire arrangement section 12 has Figure 3C The structure, and the protective part 13 (see Figure 2 )have Figure 3B The structure. Each of layers 10a to 10d may include two or more layers.

[0037] Figure 4 and Figure 5 It is shown Figure 1 and Figure 2 A plan view showing details of the protective portion 13 of the flattened clustering member 10. (See attached image.) Figure 4 As shown, the protective portion 13 is preferably embossed. Embossing can be performed, for example, by pressing. In this way, even if the protective portion 13 wears, the convex parts will wear first, and the concave parts will wear after the convex parts wear. Therefore, the embossed protective portion 13 has improved wear resistance compared to a flat protective portion 13. Since the protective portion 13 has irregularity, it also improves protection against upper surface impacts (impact dispersion) and punctures (gap formation).

[0038] like Figure 5 As shown, the protective portion 13 preferably has a mesh structure. Here, the flat bundle member 10 has a single-layer structure including a substrate layer 10a with a mesh structure, and as a result, the protective portion 13 can have a mesh structure. In the flat bundle member 10, the protective portion 13 can also have a mesh structure by providing an adhesive layer 10c only on the wire arrangement portion 12 for the substrate layer 10a with a mesh structure, or by providing an adhesive layer 10c on the entire substrate layer 10a. Furthermore, in the flat bundle member 10, the protective portion 13 can be formed by adding a mesh structure as an additional layer to both ends of a two-layer structure including the substrate layer 10a and the adhesive layer 10c.

[0039] Next, a method for manufacturing the wire harness WH according to the first embodiment will be described. Figures 6A to 6C This is a process diagram illustrating a method for manufacturing a wire harness WH according to the first embodiment, wherein... Figure 6A The first step is shown. Figure 6B The second step is shown. Figure 6C The three steps are shown.

[0040] First, prepare as follows Figure 6A The flat clustering component 10 is shown. In the flat clustering component 10, as... Figure 6A As shown, the foldable structure 11 is formed by creases 11a obtained by pre-folding the flat bundled component 10 into a mountain-shaped fold or a valley-shaped fold.

[0041] Next, in the first step, multiple wires W are fixed to the wire arrangement section 12. At this time, as shown by reference numeral 12a, the wires W can be fixed to both surfaces of the wire arrangement section 12, or as shown by reference numeral 12b, they can be fixed to one surface of the wire arrangement section 12. Depending on the specifications of the wire harness WH, there may be wire arrangement sections 12 in which no wires W are arranged.

[0042] After that, as Figure 6B As shown, the flat cluster component 10 is folded into a corrugated shape. At this time, the flat cluster component 10 can be easily folded into a corrugated shape at a predetermined position through a plurality of foldable structures 11.

[0043] Next, as Figure 6C As shown, in the flat cluster component 10, the protective parts 13 are connected to each other by connecting and fixing components 20. The connection is performed by adhesive resin tape, a nailing machine, adhesive, etc.

[0044] Figure 7 This is a table illustrating an embodiment. For example... Figure 7 As shown, in Embodiment 1, the flat bundled component has a single-layer structure including a substrate layer made of PP (thickness: 0.05 mm). The wires include a 0.13 square millimeter insulated wire, a 0.35 square millimeter insulated cable, a 0.35 square millimeter stranded wire, and a 0.5 square millimeter insulated wire. The wires are fixed to the wire assembly using a nailing machine.

[0045] Example 2 is the same as Example 1, except that the wires are fixed with adhesive. The adhesive is Adhesive G17 (manufactured by Konishi Co., Ltd.).

[0046] Example 3 is the same as Example 1, except that the wires are secured with tape. The tape used is double-sided tape No. 7021 (thickness: 0.05mm) manufactured by Teraoka Manufacturing Co., Ltd.

[0047] Example 4 is the same as Example 1 except that the thickness of the substrate layer is 0.3 mm. Example 5 is the same as Example 4 except that the wires are fixed with adhesive. The adhesive is the same as in Example 2. Example 6 is the same as Example 4 except that the wires are fixed with tape. The tape is the same as in Example 3.

[0048] Example 7 is the same as Example 1 except that the thickness of the substrate layer is 3.0 mm. Example 8 is the same as Example 7 except that the wires are fixed with tape. The tape used is the same as that used in Example 3.

[0049] Regarding embodiments 1 to 8 described above, the applicant of this application evaluated the bundling, retention, and folding properties. Regarding bundling, the presence of protruding wires was evaluated. Protrusion was attributed to insufficient adhesion between the wires and the flat bundling components, and the separation of a portion of the wire from the flat bundling components, resulting in an increase in the length of the wire clamped by the flat bundling components. The absence of protrusion was rated as "good." Regarding retention, the absence of wires falling off within 24 hours while the flat bundling components were fixed from below to a horizontal arrangement was rated as "good." Regarding folding, as... Figure 6B As shown, the evaluation assessed whether the flat bundled component folded into a corrugated shape at the intended position (the location of the foldable structure) when force was applied from both ends. Folding at the intended position was rated as "good," while cutting at the location of the foldable structure to fold in the intended position was rated as "average."

[0050] As a result, in all embodiments 1 to 8, the bundling and retention were "good". In embodiments 1 to 6, folding was also "good". In embodiments 7 and 8, folding was "general", but there were no problems with the product because it could be handled by slits. Slits are also one type of foldable structure. However, when the flat bundling component has a large thickness, a foldable structure with slits is suitable; when the flat bundling component has a small thickness, creases or components described later are preferred because the flat bundling component may tear.

[0051] Thus, the flat bundle member 10 according to the first embodiment is provided with a plurality of foldable structures 11 for folding the sheet into a corrugated shape. Therefore, after the wire W is disposed on the wire placement section 12, the sheet can be folded through the foldable structures 11. This reduces the possibility of the sheet being folded in the wrong position. Furthermore, the folding step can be performed after the wire W is disposed on the sheet, and even when the wire W is disposed in multiple layers, the number of steps can be reduced. Therefore, a flat bundle member 10 that can further improve processability can be provided.

[0052] Furthermore, a protective portion 13 is provided that connects to the outermost wire arrangement portion 12 and protects the wire W. Therefore, the wire W can not only be bundled into a flat shape, but can also be protected and used as an outer material.

[0053] Furthermore, the multiple foldable structures 11 have creases 11a formed by pre-folding into a mountain-shaped or valley-shaped fold in order to fold into a corrugated shape. Therefore, creases 11a can be pre-formed on the sheet according to the number and size of the wires W to be bundled into a flat shape, thereby making it easy to realize the foldable structure 11 and to handle various flat bundling patterns.

[0054] Furthermore, according to the wire harness WH in the first embodiment, the wire W is fixed to the wire arrangement part 12, and then the protective parts 13 at both ends are connected to each other. Therefore, the wire harness WH can be bundled flat and prevented from unwinding.

[0055] Next, a second embodiment according to this disclosure will be described. The wiring harness WH according to the second embodiment is similar to that of the first embodiment, but some of its construction differs. Hereinafter, only the differences from the first embodiment will be described. In the second embodiment, elements that are the same or similar to those in the first embodiment are denoted by the same reference numerals.

[0056] Figure 8 This is a side view showing the flat bundle member used in the wire harness WH according to the second embodiment. Figure 8 As shown, in the flat bundle member 30 used in the wire harness WH according to the second embodiment, the wire arrangement portion 12 and the protection portion 13 are formed separately from each other. In the flat bundle member 30 according to the second embodiment, the wire arrangement portion 12 and the protection portion 13 are formed with small holes, and an annular member 31 is provided as a foldable structure 11. The annular member 31 connects the wire arrangement portion 12 and the protection portion 13 to each other through the small holes formed in the wire arrangement portion 12 and the protection portion 13.

[0057] Here, in the flat bundle member 30 according to the second embodiment, the sheet is not folded with crease 11a. Therefore, the wire arrangement section 12 and the protection section 13 can be easily configured as separate components. As a result, the wire arrangement section 12 can be a component that makes it easy to secure the wires, and the protection section 13 can be a component with high abrasion resistance.

[0058] Next, a method for manufacturing the wire harness WH according to the second embodiment will be described. In the second embodiment, firstly, separate sheets corresponding to the wire arrangement section 12 and the protective section 13 are prepared. The operator makes small holes in these sheets and connects the wire arrangement section 12 and the protective section 13 to the annular member 31 through the small holes. Thereafter, as in the first embodiment, in the first step, the wire W is fixed to the wire arrangement section 12. Next, in the second step, the flat bundle member 30 is folded into a corrugated shape. At this time, the flat bundle member 30 is folded into an annular shape as the annular member 31 of the foldable structure 11. Thereafter, in the flat bundle member 30, the protective sections 13 are connected to each other by a nailing machine or the like.

[0059] Thus, similar to the first embodiment, the flat bundle member 30 and wire harness WH according to the second embodiment can be provided to further improve processability, and the flat bundle member 30 can be used as an external material. Furthermore, the wire harness WH can be flatly bundled and prevented from unwinding.

[0060] According to the second embodiment, the plurality of foldable structures 11 include an annular member 31 connecting the separately formed wire arrangement portion 12 and protective portion 13. By implementing the foldable structure 11 with the annular member 31, the wire arrangement portion 12 and the protective portion 13 can be formed separately from each other, and there is no need to fold the sheet itself. Therefore, for example, the wire arrangement portion 12 can be a component that easily secures the wires, and the protective portion 13 can be a component with high abrasion resistance. This makes it possible to set up more suitable bundled structures or protective structures.

[0061] Next, a third embodiment according to this disclosure will be described. The wire harness WH according to the third embodiment is similar to that of the first embodiment, but some of its constructions are different. Hereinafter, the differences from the first embodiment will be described. In the third embodiment, elements that are the same as or similar to those in the first embodiment are represented by the same reference numerals.

[0062] Figure 9 This is a plan view showing the flat bundle member used in the wire harness WH according to the third embodiment. Figure 9 As shown, in the flat bundle member 40 used in the wire harness WH according to the third embodiment, line bodies 41, such as linear wires, are pre-installed between the wire arrangement portions 12 and between the wire arrangement portions 12 and the protective portions 13 as a foldable structure 11. The line bodies 41 are preferably more rigid than the wire arrangement portions 12 and the protective portions 13. In the third embodiment, the line bodies 41 are embedded within the flat bundle member 40, and may also be provided on the surface.

[0063] In the flat cluster member 40 according to the third embodiment, it is not necessary to install the annular member 31. The flat cluster member 40 also does not need to have creases 11a pre-set, and can be stored in a flat state.

[0064] Next, a method for manufacturing the wire harness WH according to the third embodiment will be described. In the third embodiment, firstly, as in the first embodiment, the wire W is fixed to the wire arrangement part 12 in a first step. Next, in a second step, the flat bundle member 40 is folded into a corrugated shape. At this time, since the flat bundle member 40 includes line bodies 41, the flat bundle member 40 is easily folded starting from the line bodies 41 and folded near each line body 41. The flat bundle member 40 may also be pre-folded into a mountain-shaped fold or a valley-shaped fold near the line bodies 41 to fold into a corrugated shape. Thereafter, in the flat bundle member 40, the protective parts 13 are connected to each other by a nailing machine or the like.

[0065] Thus, according to the flat bundle member 40 and wire harness WH in the third embodiment, similar to the first embodiment, the flat bundle member 40 can be provided to further improve processability, and the flat bundle member 40 can be used as an outer material. Furthermore, the wire harness WH can be flatly bundled and prevented from unfolding.

[0066] According to the third embodiment, the foldable structure 11 includes a line body 41 disposed in a linear manner between the wire arrangement portions 12 or between the wire arrangement portions 12 and the protection portion 13. Therefore, the foldable structure 11 can be easily folded starting from the line body 41, and the foldable structure 11 can be easily realized.

[0067] Although the present disclosure has been described above based on embodiments, the present disclosure is not limited to the above embodiments. Modifications may be made without departing from the spirit of the present disclosure, and where possible, the techniques according to the embodiments may be combined with known or publicly known techniques.

[0068] Figure 10 This is a plan view illustrating an example of the corrugated folding of a flat, clustered component according to a first variation. (See diagram below.) Figure 10 As shown, the flat bundle member 50 according to the first variation can be, for example, longer than the bundle member described above, and can be folded into a corrugated shape in directions intersecting the longitudinal and transverse directions. As a result of the corrugated folding, the flat bundle member 50 can have a W shape in the plan view. That is, when viewed from a specific direction (e.g., Figure 10 When viewed (in the direction of arrow Y), the flat cluster component 50 can be folded into a corrugated shape.

[0069] Figure 11 This is a plan view illustrating an example of the corrugated folding of a flat, clustered component according to a second variation. (See diagram below.) Figure 11 As shown, the flat bundle member 60 according to the second modification may have, for example, a curved folding position, and may be folded into a corrugated shape. When the folding position is curved, a portion of the flat bundle member 60 may wrinkle. Therefore, a cut may be formed in a portion of the flat bundle member 60 to prevent wrinkling.
