Figure 3 Show Figure 1 III-III section. Figure 8 Show Figure 7 Section VIII-VIII of .

[0054] like Figure 1 and Figure 2As shown, the wire harness protector 1 of this embodiment is a component that is mounted on the wire harness WH to protect the wire harness WH. The wire harness protector 1 includes a protective body 2 and a fixing portion 3. The protective body 2 is wound around the outside of the wire harness WH to protect the wire harness WH. The fixing portion 3 fixes the two end portions 2a, 2a of the protective body 2 to each other.

[0055] like Figure 3 As shown, the protective body 2 is formed by overlapping a plurality of sheets 10. The fixing portion 3 fixes the plurality of sheets 10 to each other along the stacking direction Ly in which the sheets 10 are stacked. The fixing portion 3 is formed, for example, by welding. However, the fixing portion 3 may also be a component attached to the protective body 2, for example, a clip or a binding component.

[0056] In the wire harness protector 1 of the present embodiment, the rigidity and flexibility of the protector 2 can be adjusted by the number of stacked sheets 10. In other words, it is possible to configure a protector 2 having different protective performances corresponding to the number of sheets 10 used. In the wire harness protector 1 of the present embodiment, since it is not necessary to separately keep a plurality of protectors of different shapes as inventory, inventory management can be simplified.

[0057] like Figure 4 As shown, the shape of the sheet 10 of this embodiment is rectangular. The sheet 10 is formed of a flexible insulating synthetic resin. The material of the sheet 10 is, for example, soft polyvinyl chloride (PVC). The illustrated sheet 10 has a flat plate shape. The thickness t [mm] of the sheet 10 is determined in such a way that the sheet 10 has appropriate flexibility and appropriate strength.

[0058] like Figure 5 As shown, the protective body 2 is formed by overlapping a plurality of sheets 10. The plurality of sheets 10 constituting the protective body 2 have the same material and the same shape. That is, the material and shape of one sheet 10 constituting the protective body 2 are the same as the material and shape of the other sheets 10 constituting the protective body 2. All the sheets 10 have the same size. For example, when the shape of the sheet 10 is a rectangle, the lengths of the corresponding sides 11 and 12 and the thickness t of the plurality of sheets 10 are the same.

[0059] like Figure 5 As shown, a plurality of sheets 10 are overlapped in a manner that one sheet 10 covers the entirety of another sheet 10. The rectangular sheet 10 shown in the example has a pair of first sides 11 and a pair of second sides 12. The first side 11 of one sheet 10 overlaps with the first side 11 of another sheet 10, and the second side 12 of one sheet 10 overlaps with the second side 12 of another sheet 10.

[0060] like Figure 6As shown, the protective body 2 is wound around the wire harness WH. The wire harness WH includes at least one wire W. The exemplary wire harness WH includes a plurality of wires W. The protective body 2 is wound around the wire harness WH in a manner of covering the wire harness WH. In addition, the protective body 2 may be held in advance by a clamp or the like in a manner of having a substantially U-shape or a V-shape. In this case, the wire harness WH is placed on the held protective body 2.

[0061] The protector 2 wound around the wire harness WH has an inner side surface 2b. The inner side surface 2b is a surface facing the wire harness WH and forms a space portion for accommodating the wire harness WH. The protector 2 is wound around the wire harness WH so that the inner side surfaces 2b of both end portions 2a face each other.

[0062] The fixing portion 3 that fixes the two end portions 2a to each other is formed, for example, by a welding machine 100. The welding means by the welding machine 100 may be ultrasonic welding, heat welding, laser welding, or other means. The welding machine 100, for example, clamps the two end portions 2a, melts the plurality of sheets 10 using heat generated by ultrasonic waves, and forms the fixing portion 3.

[0063] like Figure 3 As shown, a portion of the sheet 10 is melted to form a fixing portion 3. The fixing portion 3 extends from one end 2a to the other end 2a along the stacking direction Ly. In other words, the fixing portion 3 penetrates through the plurality of sheets 10 along the stacking direction Ly. By forming the fixing portion 3, the opening between the two end portions 2a is closed. Figure 3 As shown, a plurality of sheets 10 are fixed at the same position in the opening of the protection body 2 .

[0064] In addition, since the protective body 2 is wound around the wire harness WH, there is a possibility that the position of the end face 2c of the sheet 10 is offset. This offset is caused, for example, by the difference in the inner and outer peripheries of the portion wound around the wire harness WH. The end face 2c of the sheet 10 located on the relatively inner side protrudes relative to the end face 2c of the sheet 10 located on the relatively outer side.

[0065] Even in the case where such a deviation occurs, one sheet 10 overlaps in a manner that covers the entirety of the other sheet 10. For example, Figure 3 The protective body 2 has three sheets 10A, 10B, and 10C. The sheet 10A is located on the outermost side, and the sheet 10C is located on the innermost side. The sheet 10B overlaps with the sheet 10A in a manner that covers the entire sheet 10A. The sheet 10C overlaps with the sheet 10B in a manner that covers the entire sheet 10B.

[0066] like Figure 2 As shown, the wire harness protector 1 may include a plurality of fixing portions 3 . Figure 2The plurality of fixing portions 3 shown are arranged at intervals along the axial direction X of the wire harness WH. The plurality of fixing portions 3 may also be arranged at equal intervals. For the portion between two fixing portions 3, the plurality of sheets 10 can slide, or the plurality of sheets 10 can be separated. Therefore, the wire harness protector 1 having the plurality of fixing portions 3 can be flexibly bent. That is, the wire harness protector 1 having the plurality of fixing portions 3 has high tracking performance with respect to the wire harness WH that is laid while being bent.

[0067] In addition, the sheet 10 may also have concave portions and convex portions. Figure 7 and Figure 8 2 shows a sheet 10 having a curved portion 13 curved in a spherical shape. Figure 7 The sheet 10 has a plurality of curved portions 13. Figure 8 As shown, the curved portion 13 is curved toward one side in the thickness direction Z of the sheet 10. One surface of the curved portion 13 is a convex surface, and the other surface of the curved portion 13 is a concave surface.

[0068] The rigidity and bendability of the sheet 10 can be adjusted by the arrangement of the curved portion 13. Fig. 9 In the sheet 10 shown, the plurality of curved portions 13 are arranged in a grid shape. That is, the plurality of curved portions 13 are arranged along a first direction D1 and a second direction D2. The first direction D1 is a direction along the first side 11, and the second direction D2 is a direction along the second side 12. The first direction D1 and the second direction D2 are orthogonal to each other.

[0069] When the plurality of curved portions 13 are arranged in a lattice, a region 18 having high bendability is formed between adjacent curved portions 13. Such a sheet 10 has high bendability in a state of being wound around the wire harness WH.

[0070] exist Fig.10 In the sheet 10 shown, the plurality of curved portions 13 are staggered in different ways. The plurality of curved portions 13 include a first row R1 and a second row R2. The first row R1 and the second row R2 include a plurality of curved portions 13 arranged in a first direction D1. The first row R1 and the second row R2 are staggered in the first direction D1. For example, in the first direction D1, the curved portion 13 of the second row R2 is arranged between two curved portions 13 of the first row R1.

[0071] Fig.10 The sheet 10 is wound around the wire harness WH, for example, with the portion along the first side 11 as the end 2a. The sheet 10 in which the plurality of bending portions 13 are arranged differently from each other has high rigidity when wound around the wire harness WH. Such a sheet 10 can improve the rigidity of the wire harness protector 1 with respect to bending. In addition, in addition to the first column R1 and the second column R2, the sheet 10 may also have other columns. In other words, the sheet 10 may also have bending portions 13 arranged in three or more columns.

[0072] The sheets 10 having the curved portions 13 may be overlapped in such a manner that the curved portions 13 fit into each other. That is, a plurality of sheets 10 may be overlapped in such a manner that the curved portion 13 of one sheet 10 enters the curved portion 13 of another sheet 10. Alternatively, a plurality of sheets 10 may be overlapped in such a manner that the positions of the curved portions 13 are staggered. In this case, a gap is formed between the two sheets 10, and the rigidity and impact resistance of the wire harness protector 1 are improved.

[0073] The protective body 2 may be wound around the wire harness WH with the convex surface of the bent portion 13 facing outward. In this case, the contact between the peripheral elements and the wire harness protective member 1 becomes point contact, and the wear resistance of the wire harness protective member 1 is improved. In addition, the contact area with the peripheral elements is small, thereby suppressing the generation of abnormal noise.

[0074] The shape of the curved portion provided in the sheet 10 is not limited to a spherical shape. Fig.11 2 shows a sheet 10 having a groove-shaped curved portion 14. The sheet 10 has a plurality of curved portions 14. The curved portion 14 extends linearly and has an arc-shaped cross-sectional shape. Fig.11 The bent portions 14 extend along the second direction D2. A predetermined interval is provided between two adjacent bent portions 14. The plurality of bent portions 14 are arranged at equal intervals, for example, along the first direction D1.

[0075] The sheet 10 is wound around the wire harness WH, for example, with the portion along the second side 12 as the end portion 2a. In this case, the sheet 10 can improve the rigidity of the wire harness protector 1 against bending. Alternatively, the sheet 10 can be wound around the wire harness WH with the portion along the first side 11 as the end portion 2a. In this case, the sheet 10 can bend flexibly following the wire harness WH.

[0076] The sheets 10 having the curved portion 14 are overlapped, for example, in such a manner that the curved portions 14 fit into each other. That is, in the protective body 2, a plurality of sheets 10 may be overlapped in such a manner that the curved portion 14 of one sheet 10 enters the curved portion 14 of another sheet 10. Different from this, a plurality of sheets 10 may be overlapped in such a manner that the positions of the curved portions 14 are staggered. In addition, a plurality of sheets 10 may be overlapped in such a manner that the curved portions 14 protrude in opposite directions to each other. In this case, a gap is formed between the two sheets 10 at the portion where the convex surfaces of the curved portions 14 contact each other.

[0077] The wire harness protector 1 may include the fixing portion 3 provided in a linear shape. Fig.12 The wire harness protector 1 having a linear fixing portion 3 is shown. The fixing portion 3 extends linearly along the axial direction X. The fixing portion 3 is provided, for example, from one end of the end portion 2a to the other end in the axial direction X. The linear fixing portion 3 can increase the rigidity of the end portion 2a and improve the straightness of the wire harness WH.

[0078] You can also use Fig.13 The strapping member 30 shown is used as the fixing portion 3. The strapping member 30 is, for example, a member called a strapping tape, and has a head portion 31 and a belt portion 32. The belt portion 32 is inserted into a through hole 2d provided at the end portion 2a of the protective body 2, and engages with the head portion 31. The strapping member 30 fixes the plurality of sheets 10 to each other along the stacking direction Ly. The through hole 2d is formed in each sheet 10 constituting the protective body 2. The plurality of sheets 10 are overlapped in a manner that the through holes 2d are opposed to each other. The protective body 2 shown in the example has a plurality of through holes 2d. The plurality of through holes 2d are arranged at intervals along the axial direction X.

[0079] You can also use Fig.14 and Fig.15 The clip 40 shown serves as the fixing portion 3. The clip 40 is a fastening member called a two-piece clip or a push rivet. Fig.14 and Fig.15 The clip 40 shown has a head 41, a pin 42, and a plurality of legs 43. The pin 42 penetrates the head 41. The pin 42 and the legs 43 are inserted into the through hole of the protective body 2. The clip 40 is configured such that the legs 43 are expanded by pressing the pin 42. The clip 40 sandwiches a plurality of sheets 10 between the expanded legs 43 and the head 41, and fastens the two end portions 2a of the protective body 2. The clip 40 fixes the plurality of sheets 10 to each other along the stacking direction Ly.

[0080] In addition, in the formation Fig.12 In the case of such a linear fixing portion 3, for example, a linear clip such as a clip called a cover clip or a sealing clip may be used. Fig.16 2 shows a side view of the protection body 2 fastened by a linear clip 50. The clip 50 has two holding bodies 51 and an engaging structure 52. The clip 50 is molded of, for example, an insulating synthetic resin.

[0081] The retaining body 51 holds the two end portions 2a of the protective body 2 by clamping. The two retaining bodies 51 are formed into a plate or rod shape so that the two end portions 2a are located in the middle and face each other in the stacking direction Ly. The two retaining bodies 51 are clamped by a snap-fit ​​structure 52. The snap-fit ​​structure 52 is composed, for example, of a snap-fit ​​arm 52a possessed by one retaining body 51 and a stopper 52b possessed by the other retaining body 51. In this case, the stopper 52b stops the snap-fit ​​arm 52a in the stacking direction Ly. The snap-fit ​​structure 52 is arranged at both ends of the axial direction X relative to the retaining body 51. The clip 50 can fix a plurality of sheets 10 to each other along the stacking direction Ly. In addition, in addition to the two ends of the retaining body 51, a snap-fit ​​structure can also be further provided in the middle portion of the retaining body 51.

[0082] Next, other structural examples of the sheet 10 will be described. Fig.17The sheet material 10 shown has a base material layer 15 and an adhesive layer 16. The base material layer 15 is the main body of the sheet material 10, and is formed of, for example, soft polyvinyl chloride (PVC). The adhesive layer 16 is formed, for example, by applying an adhesive to the base material layer 15. The adhesive layer 16 may also be an adhesive sheet or an adhesive tape attached to the base material layer 15.

[0083] The sheet 10 is bonded to other sheets 10 by the adhesive layer 16. For example, the plurality of sheets 10 Fig.18 Overlap as shown. Fig.18 In the protective body 2 , the adhesive layer 16 is located on the same side with respect to the base material layer 15 in all the sheets 10 . Fig.18 The protective body 2 shown is wound around the wire harness WH, for example, so that the adhesive layer 16 exposed on the surface layer faces the wire harness WH.

[0084] In this case, if Fig.19 As shown, the adhesive layer 16 is bonded to the wire harness WH to restrain the wire harness WH. As a result, the wire harness protection member 1 can improve the straightness of the wire harness WH. In addition, the wire harness protection member 1 can improve the straightness of the wire harness WH by bonding the plurality of sheets 10 to each other.

[0085] The end portion 2a is fixed to the protective body 2 wound around the wire harness WH by the fixing portion 3. The fixing portion 3 may be formed by welding, or may be a binding member, a clip, or the like. When the fixing portion 3 is a binding member or a clip, a through hole 2d is provided in the base material layer 15 and the adhesive layer 16.

[0086] The protection body 2 having the adhesive layer 16 may have a plurality of fixing portions 3 disposed along the axial direction X, or may have a linear fixing portion 3 disposed along the axial direction X. In addition to being fixed to each other by the fixing portions 3, the two end portions 2a are also fixed to each other by the adhesive layer 16. Therefore, the fixing strength of the opening is improved.

[0087] In addition, the plurality of sheets 10 may be overlapped so that the base material layer 15 and the wire harness WH face each other. Fig. 20 As shown, the sheet 10 arranged at the end of the stacking direction Ly makes the adhesive layer 16 face the adhesive layer 16 of the other sheet 10. That is, the adhesive layers 16 of the two sheets 10 are bonded to each other. Such a protective body 2 is wound around the wire harness WH in such a manner that the base material layer 15 faces the wire harness WH. In this case, it is difficult for the wire harness protective member 1 to restrict the movement of the wire harness WH, so the bending property of the wire harness WH can be improved. In addition, as the sheet 10 arranged at the end of the stacking direction Ly, a sheet 10 without the adhesive layer 16 can also be used.

[0088] The sheet 10 having the adhesive layer 16 may have a spherical curved portion 13, a groove-shaped curved portion 14, or a curved portion of other shapes. A plurality of sheets 10 having a curved portion 13 may be overlapped in a manner that the curved portions 13 fit together, or in a manner that the positions of the curved portions 13 are staggered. A plurality of sheets 10 having a curved portion 14 may be overlapped in a manner that the curved portions 14 fit together, or in a manner that the positions of the curved portions 14 are staggered.

[0089] As described above, the wire harness protector 1 of this embodiment includes the protector 2 and the fixing portion 3. The protector 2 is formed by overlapping a plurality of sheets 10. The fixing portion 3 fixes both end portions 2a of the protector 2. The plurality of sheets 10 have the same material and the same shape.

[0090] In the protective body 2, a plurality of sheets 10 are overlapped in a manner that one sheet 10 covers the entirety of another sheet 10. The protective body 2 has an inner side surface 2b that is opposite to the wire harness WH when wound on the wire harness WH. The protective body 2 is wound on the wire harness WH in a manner that the inner side surfaces 2b of the two end portions 2a of the protective body 2 are opposite to each other. The fixing portion 3 fixes the plurality of sheets 10 to each other along a stacking direction Ly in which the plurality of sheets 10 are stacked. In the protective part 1 for wire harnesses involved in the present embodiment, protective parts with different required protective performances can be manufactured from the same sheet 10. Therefore, according to the protective part 1 for wire harnesses of the present embodiment, the types of components required for protective parts with different protective performances can be reduced.

[0091] The sheet material 10 may include a base material layer 15 and an adhesive layer 16, and may be bonded to another sheet material 10 via the adhesive layer 16. Such a sheet material 10 can improve the rigidity of the wire harness protector 1.

[0092] The fixing portion 3 may be formed by welding a plurality of sheets 10. In this case, the process of forming the fixing portion 3 can be automated and efficiency can be improved.

[0093] In the wire harness protector 1 , the plurality of fixing portions 3 may be arranged at intervals along the axial direction X of the wire harness WH. In this case, the wire harness protector 1 can be flexibly bent.

[0094] In addition, when the protective body 2 is composed of a sheet 10 without an adhesive layer 16, a structure for suppressing positional deviation of the sheet 10 may be provided. Fig.21 As shown, a welded portion 17 where a plurality of sheets 10 are welded together may be formed. Fig.21 The protection body 2 has a plurality of welded portions 17. The welded portions 17 are formed so as to penetrate the protection body 2 along the stacking direction Ly.

[0095] The plurality of welded portions 17 are arranged along the axial direction X of the wire harness WH when the wire harness WH is wound. Fig.21 In the protective body 2, a plurality of welded portions 17 are arranged in the second direction D2. In this case, the protective body 2 is wound around the wire harness WH so that the wire harness WH extends in the second direction D2. By arranging the plurality of welded portions 17 at intervals, the bendability of the wire harness protector 1 is improved. The welded portion 17 is, for example, arranged in the center of the protective body 2 in the first direction D1.

[0096] like Fig. 22 As shown, the welded portion 17 may also be formed in a straight line. Fig. 22 The welded portion 17 extends along the axial direction X of the wire harness WH when the wire harness WH is wound around the wire harness WH. The linear welded portion 17 can improve the straightness of the wire harness protector 1 .

[0097] In the case where the protective body 2 is formed of a sheet 10 without an adhesive layer 16, a jig that suppresses positional deviation of the sheet 10 may be used. For example, a jig having a positioning pin that penetrates the protective body 2 is used. In this case, for example, each sheet 10 is provided with a through hole corresponding to the positioning pin. The jig supports the protective body 2 and positions the plurality of sheets 10 by the positioning pin. The wire harness WH is placed on the protective body 2 supported by the jig, for example.

[0098] The shape of the sheet 10 is not limited to the shape exemplified in the embodiment. The shape of the sheet 10 in a plan view may be a polygonal shape such as a hexagon, an oval shape, or other shapes.

[0099] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
