DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] First, the embodiments of the present disclosure will be listed and described. [1] The wire protection material disclosed herein is configured to protect the outer peripheral surface of an electric wire arranged at an electric wire arrangement location, and a protective material main body interposed between an interference portion present at the electric wire arrangement location and the electric wire is formed in a planar shape.

[0011] According to this configuration, since the protective material body of the wire protective material is planar, it is possible to bend the wire protective material. This makes it possible to arrange the wire protective material along the shape of the wire installation location. Therefore, even when a configuration is adopted in which the wire protective material protects the outer circumferential surface of the wire, the wire does not have linear rigidity, and it is possible to arrange the wire together with the wire protective material along the shape of the wire installation location. This makes it possible to improve the ease of installation of the wire.

[0012] [2] The wire protective material has a tongue provided at least on one of both ends in the longitudinal direction of the protective material body. The tongue is attached to the wire by a first fixation in which a fixing member for fixing the wire to the wire installation location is interposed between the wire and the tongue, a second fixation in which the fixing member is not interposed, or a combination of these. With this configuration, it is possible to assemble the wire protective material to the wire using an appropriate fixing method out of the first fixation, the second fixation, and a combination of these, depending on the shape of the wire installation location. This further contributes to improving the ease of installation of the wire.

[0013] [3] The first fixing is a structure in which the tongue is brought into contact with and fixed to the fixing member attached to the electric wire. With this configuration, the electric wire is assembled integrally with the fixing member, and the wire protection member is fixed to this assembly, so that the first fixing structure can have a plurality of fixing points. This makes it possible to securely fix the electric wire, the wire protection member, and the fixing member. In addition, since the tongue is fixed based on the fixing member attached and fixed to the electric wire, it is possible to position the wire protection member relative to the electric wire.

[0014] [4] The first and second fixings are configured to assemble the tongue piece to the electric wire by wrapping a tape member around the electric wire. With this configuration, it is possible to fix the wire protection member to the electric wire by a simple method using a tape member.

[0015] [5] The fixing member has an engagement portion that engages with the electric wire arrangement location and an arm portion that extends from the engagement portion. The first fixation is a structure in which the arm portion is interposed between the electric wire and the tongue. With this configuration, it is possible to fix the tongue of the wire protection material by wrapping it around the arm portion of the fixing member. Therefore, it is possible to firmly attach the wire protection material to the electric wire.

[0016] [6] The tongue is formed in a shape that makes surface contact with the arm. With this configuration, the surface when the tongue is placed against the arm is flat, so the tongue is less likely to shift out of position. This makes it possible to make the wire protection material less likely to shift out of position after being attached to the wire routing location. In addition, it is possible to ensure a large contact area between the tongue of the wire protection material and the fixing member, so that the wire protection material can be firmly pressed against the fixing member.

[0017] [7] The fixing member has the arm portion on only one side of the engaging portion. The electric wire, the tongue, and the arm portion are aligned so that their axes are aligned in the stacking direction. This configuration allows the electric wire, the tongue, and the arm portion to be stacked, making it possible to compactly organize this portion.

[0018] [8] The protective material body has flexibility. With this configuration, when the wire protective material is disposed at an electric wire installation location, it is less affected by the shape of the electric wire installation location. This is advantageous for disposing the wire protective material at the electric wire installation location without any gaps.

[0019] [9] The protective material main body has a displacement-permitting portion that prevents the electric wire from protruding from the protective material main body even if the electric wire moves in a planar direction of the protective material main body. With this configuration, even if the electric wire is displaced in a planar direction of the protective material main body when the electric wire is assembled or when the electric wire vibrates, the electric wire is unlikely to protrude from the wire protective material. Therefore, it is possible to appropriately protect the electric wire.

[0020]

[10] The wire harness of the present disclosure includes an electric wire arranged in an electric wire arrangement location, a fixing member that fixes the electric wire to the electric wire arrangement location, and an electric wire protection material that protects an outer peripheral surface of the electric wire, and the electric wire protection material has a protection material main body that is formed in a planar shape and is interposed between the electric wire and an interference portion present at the electric wire arrangement location.

[0021] According to this configuration, the same effects as those of the wire protective material can be obtained, and therefore it is possible to improve the ease of routing of the wires and therefore the wiring harness.

[11] A bend-allowing protective layer that can bend together with the electric wire while protecting the electric wire is provided on at least a portion of the outer peripheral surface of the electric wire where the wire protective material is laid. With this configuration, even when the electric wire is bent, the outer peripheral surface of the electric wire can be suitably protected.

[0022]

[12] A rigid protective layer is provided on at least a portion of the outer circumferential surface of the electric wire that is stepped on by a user. According to this configuration, the portion of the outer circumferential surface of the electric wire that is frequently stepped on by a user is protected by the rigid protective layer, so that the electric wire can be protected more effectively.

[0023]

[13] The wire protection material has a tongue provided at least at one of both ends in the longitudinal direction of the protection material body. The tongue is attached to the wire by a first fixation in which a fixing member for fixing the wire to the wire installation location is interposed between the tongue and the wire, a second fixation in which the fixing member is not interposed, or a combination of these. With this configuration, the same effect as that of the wire protection material can be obtained.

[0024]

[14] The fixing member has an engagement portion that engages with the electric wire arrangement location and an arm portion that extends from the engagement portion to only one side. The first fixation is a structure in which the arm portion is interposed between the electric wire and the tongue, and the wire protection material is fixed to the electric wire. According to this configuration, it is possible to position the wire protection material with respect to the electric wire by fixing the tongue of the wire protection material based on the arm portion of the fixing member.

[0025]

[15] The fixing member includes a first fixing member involved in assembling the wire protection member to the wire, and a second fixing member not involved in assembling the wire protection member to the wire. The second fixing member has an engagement portion that is engaged with the wire routing location, and a pair of arms extending on both sides from the engagement portion, and the pair of arms are directly fixed to the wire. With this configuration, the position of the second fixing member is not affected by the wire protection member. Therefore, the second fixing member can be freely positioned, making it possible to attach the second fixing member to an optimal position.

[0026] [Details of the embodiment of the present disclosure] Specific examples of the wire protective material and wire harness of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, some of the configurations may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from the actual ones.

[0027] [Wire harness 1 installation overview] As shown in Fig. 1, a wire harness 1 that electrically connects electrical components is arranged in an electric wire arrangement location 2. The wire harness 1 is, for example, an in-vehicle harness. In this case, the electric wire arrangement location 2 includes, for example, a floor surface 3 inside the vehicle and an upright wall 4 erected against the floor surface 3. In this way, the wire harness 1 is arranged in a location that is likely to be stepped on directly or indirectly by a user.

[0028] [Outline of Wire Protection Material 8] 1, a wire protection material 8 that protects the outer peripheral surface of an electric wire 7 is interposed between a wire harness 1 and an electric wire arrangement location 2. The wire protection material 8 has a protection material main body 10 formed in a planar shape and interposed between an interference portion 9 present at the electric wire arrangement location 2 and the electric wire 7. In this way, the wire protection material 8 is a protection plate (protective sheet) that protects the outer peripheral surface of the electric wire 7. The interference portion 9 is, for example, a welding burr that occurs at the boundary between metal materials.

[0029] As shown in Fig. 2, the protective material body 10 is formed, for example, in a substantially rectangular shape. The protective material body 10 is flexible. The wire protective material 8 is capable of bending at least at the protective material body 10. The wire protective material 8 is preferably made of, for example, a resin, and PP (polypropylene) is used as one example. The wire protective material 8 is inexpensively manufactured, for example, by punching a plate material out of PP.

[0030] The wire protection material 8 includes a tongue piece 11 provided at at least one end (both ends in this example) of both ends in the length direction (X-axis direction in FIG. 2) of the protection material body 10. The tongue piece 11 is formed so as to protrude in the length direction from the center in the width direction (Y-axis direction in FIG. 2) of the protection material body 10. In this example, the tongue piece 11 includes a first tongue piece 11a arranged along the standing wall 4 and a second tongue piece 11b arranged along the floor surface 3. The length La of the first tongue piece 11a is longer than the length Lb of the second tongue piece 11b (La>Lb). A hook portion 12 is formed at the tip of the tongue piece 11, protruding on both sides in the width direction (Y-axis direction in FIG. 2) of the wire protection material 8.

[0031] [Outline of Cable 7] As shown in Fig. 3, the electric wire 7 includes an electric wire body 14 consisting of one or more electric wirings. At least a part of the outer peripheral surface of the electric wire 7 (electric wire body 14) where the user steps is provided with a hard protective layer 15 that protects the electric wire 7 while having rigidity. The hard protective layer 15 is, for example, a sheet material, and is wound around the electric wire body 14. The hard protective layer 15 is formed to a length that reaches the second tongue piece 11b of the wire protection material 8.

[0032] At least a portion of the outer peripheral surface of the electric wire 7 (electric wire main body 14) where the wire protective material 8 is laid is provided with a bend-allowing protective layer 16 that can bend together with the electric wire 7 while protecting the electric wire 7. The bend-allowing protective layer 16 is, for example, a sheet material, and is wound around the electric wire main body 14. In this example, the bend-allowing protective layer 16 is formed to have the same or approximately the same length as the protective material main body 10.

[0033] It is preferable that the electric wire body 14 is wrapped with a tape 17 having no protective function, and the hard protective layer 15 and the bend-permitting protective layer 16 are provided on the outside of the tape 17. Therefore, the tape 17 is exposed to the outside in the portions of the electric wire 7 (electric wire body 14) where the hard protective layer 15 and the bend-permitting protective layer 16 are not provided. It is not necessary that the tape 17 is provided on the entire surface of the electric wire body 14, and it may be omitted, for example, in the portion of the bend-permitting protective layer 16.

[0034] [Outline of fixing wire harness 1 to wire routing location 2] As shown in Fig. 1, the wire harness 1 is attached and fixed to an electric wire routing location 2 by two fixing members 20. In this example, the wire harness 1 is fixed to the electric wire routing location 2 at two locations, a floor surface 3 and a standing wall 4. The fixing members 20 used for fixing to the standing wall 4 are referred to as a "first fixing member 20a," and the fixing member 20 used for fixing to the floor surface 3 is referred to as a "second fixing member 20b." The fixing members 20 are so-called clamps.

[0035] The first fixing member 20a has an engaging portion 21 that engages with the electric wire arrangement location 2, and an arm portion 22 that extends from the engaging portion 21 to only one side. The first fixing member 20a is a so-called "single-arm clamp." The second fixing member 20b has an engaging portion 23 that engages with the electric wire arrangement location 2, and a pair of arm portions 24 that extend from the engaging portion 23 to both sides. The second fixing member 20b is a so-called "double-arm clamp." In addition, in this example, the first fixing member 20a is involved in the assembly of the wire protection member 8 to the electric wire 7, but the second fixing member 20b is not involved.

[0036] [Outline of fixing the wire protection material 8 to the wire 7] 4 and 5, the tongue piece 11 is attached to the electric wire 7 by a first fixation in which a fixing member 20 for fixing the electric wire 7 to the electric wire installation location 2 is interposed between the tongue piece 11 and the electric wire 7, a second fixation in which the fixing member 20 is not interposed, or a combination of these. In this example, the first fixation is used for the first tongue piece 11a, and the second fixation is used for the second tongue piece 11b. That is, the first tongue piece 11a is fixed to the electric wire 7 with the first fixing member 20a sandwiched therebetween. On the other hand, the second tongue piece 11b is fixed directly to the electric wire 7 without the second fixing member 20b being interposed.

[0037] The first fixing is a structure in which the tongue 11 (first tongue 11a) is brought into contact with and fixed to the fixing member 20 (first fixing member 20a) attached and fixed to the electric wire 7. Specifically, first, the electric wire 7 and the first fixing member 20a are fixed by wrapping tape around them, and then the first tongue 11a of the wire protection member 8 is fixed to this assembly.

[0038] The first and second fixings are structures in which the tape member 26 (26a, 26b) is wound around the periphery to assemble the tongue to the electric wire. Specifically, the first fixing is, for example, a structure in which an assembly in which the electric wire 7 is placed on the arm portion 22 of the first fixing member 20a is wrapped around the periphery with the tape member 26a in a state in which the arm portion 22 of the first fixing member 20a is sandwiched between the electric wire 7 and the first tongue portion 11a, thereby assembling them together. Therefore, the electric wire 7, the first tongue portion 11a, and the arm portion 22 are fixed together by wrapping the tape member 26a around the periphery with the arm portion 22 positioned between the electric wire 7 and the first tongue portion 11a. In this way, the first fixing is a structure in which the wire protection member 8 is fixed to the electric wire 7 by interposing the arm portion 22 between the electric wire 7 and the first tongue portion 11a. The second fixing is performed, for example, by placing the electric wire 7 on the second tongue piece 11b and wrapping the periphery thereof with the tape member 26b, thereby assembling them together.

[0039] The protective material body 10 has a displacement allowing portion 27 that prevents the electric wire 7 from protruding from the protective material body 10 even if the electric wire 7 moves in the planar direction of the protective material body 10. In this example, the displacement allowing portion 27 is provided on both sides in the width direction of the protective material body 10. Also, the displacement allowing portion 27 is a sheet portion that is integrated with the protective material body 10.

[0040] The second fixing member 20b has a pair of arms 24 directly fixed to the electric wire 7. In the case of this example, the second fixing member 20b is fixed integrally to the electric wire 7 by wrapping a tape 28 around each of the pair of arms 24 around the electric wire 7.

[0041] As shown in Fig. 6, the first tongue 11a is formed in a shape that makes surface contact with the arm 22 of the first fixing member 20a. This allows the first tongue 11a to be placed on the plane of the arm 22, rather than directly contacting the outer periphery (curved surface) of the electric wire 7. The electric wire 7, the first tongue 11a, and the arm 22 are arranged in an aligned manner such that their axes P are aligned in the stacking direction (Z-axis direction in Fig. 6). That is, if the axis P of the electric wire 7 is "P1", the axis P of the first tongue 11a is "P2", and the axis P of the arm 22 is P3, the axes P1 to P3 are arranged in a straight line aligned in the vertical direction.

[0042] [Effect] Next, the operation of the wire protective material 8 (wire harness 1) of this embodiment will be described. 7, in this example, since the wire protective material 8 is plate-shaped (flat), when the wire harness 1 is shipped, the wire harness 1 can be folded and packed at the portion of the wire protective material 8. Therefore, the wire harness 1 is compactly stored in an approximate U-shape, which makes it easy to handle during transportation.

[0043] As shown in Fig. 8, when attaching the wire harness 1 to the electric wire routing location 2, the packaged wire harness 1 is taken out, and the fallen electric wires 7 are raised up to make the wire harness 1 into a shape of the letter L. Then, the engaging portion 21 of the first fixing member 20a is engaged with the engaged portion 30 (shown in Fig. 9) of the standing wall 4, and the engaging portion 23 of the second fixing member 20b is engaged with the engaged portion 31 (shown in Fig. 1) of the floor surface 3. In this example, the engaged portion 30 is, for example, a recess (hole). The engaged portion 31 is a recess (hole) provided in a base 32 (shown in Fig. 1) of the floor surface 3.

[0044] As shown in Fig. 9, the wire protection material 8 is bound and fixed to the first fixing member 20a with the tape member 26a, so that when the first fixing member 20a is fixed to the engaged portion 30, it is possible to press the wire protection material 8 in the attachment direction of the first fixing member 20a (the direction of the arrow A in Fig. 9). In other words, it is possible to arrange the wire protection material 8 along the electric wire routing location 2 with little gap.

[0045] As shown in Fig. 10, even if the wire harness 1 has excess length, the excess length can be absorbed by the bending angle of the wire protective material 8. In other words, if the wire harness 1 has excess length, by pushing the wire harness 1 in by the excess length, the wire protective material 8 bends to go inward accordingly, and the wire harness 1 can be arranged along the electric wire routing location 2. Furthermore, the height H of the wire harness 1 is only the thickness of the electric wire main body 14, the protective layers surrounding it (the hard protective layer 15, the bend-allowing protective layer 16), and the wire protective material 8. Therefore, the height H of the wire harness 1 can be kept low.

[0046] 11, when the harness position is adjusted during installation of the wire harness 1 or when vibrations occur in the vehicle, the electric wires 7 may swing left and right (in the directions of arrows B1 and B2 in the figure) along the planar direction of the wire protection material 8. In this example, because the displacement allowing portions 27 are provided on both sides of the protection material main body 10, it is possible to maintain the state in which the electric wires 7 rest on the wire protection material 8 even if the electric wires 7 swing left and right. This makes it possible to reduce the likelihood of a situation in which the electric wires 7 are damaged.

[0047] According to the wire protective material 8 (wire harness 1) of the above embodiment, the following effects can be obtained. (1) The wire protection material 8 protects the outer peripheral surface of the electric wire 7 arranged in the electric wire installation location 2. The wire protection material 8 has a protection material main body 10 formed in a planar shape and interposed between an interference portion 9 present in the electric wire installation location 2 and the electric wire.

[0048] According to this configuration, the protective material body 10 of the wire protective material 8 is planar, so that the wire protective material 8 can be bent. This makes it possible to arrange the wire protective material 8 along the shape of the wire installation location 2. Therefore, even when a configuration is adopted in which the wire protective material 8 protects the outer circumferential surface of the wire 7, linear rigidity is not generated in the wire 7, and it becomes possible to arrange the wire 7 together with the wire protective material 8 along the shape of the wire installation location 2. This improves the ease of installation of the wire 7.

[0049] (2) The wire protective material 8 includes a tongue piece 11 provided on at least one of both ends in the longitudinal direction of the protective material body 10. The tongue piece 11 is attached to the wire 7 by a first fixation in which a fixing member 20 for fixing the wire 7 to the wire installation location 2 is interposed between the wire 7, a second fixation in which the fixing member 20 is not interposed, or a combination of these. With this configuration, it becomes possible to assemble the wire protective material 8 to the wire 7 by using an appropriate optimal fixing method out of the first fixation, the second fixation, and a combination of these depending on the shape of the wire installation location 2. This further contributes to improving the ease of installation of the wire 7.

[0050] (3) The first fixation has a structure in which the tongue 11 (first tongue 11a in this example) is brought into contact with and fixed to the fixing member 20 (first fixing member 20a in this example) that is attached and fixed to the electric wire 7. With this configuration, the electric wire 7 is assembled integrally with the fixing member 20, and the wire protection member 8 is fixed to this assembly, so that the first fixation structure can have a plurality of fixing points. This makes it possible to securely fix the electric wire 7, the wire protection member 8, and the fixing member 20. Furthermore, since the tongue 11 is fixed based on the fixing member 20 that is attached and fixed to the electric wire 7, the wire protection member 8 can be positioned with respect to the electric wire 7.

[0051] (4) The first and second fixings are configured to assemble the tongue piece 11 to the electric wire by wrapping the tape member 26 around the electric wire. With this configuration, the wire protection member 8 can be fixed to the electric wire 7 by a simple method using the tape member 26.

[0052] (5) The fixing member 20 (in this example, the first fixing member 20a) has an engaging portion 21 that engages with the electric wire installation location 2, and an arm portion 22 extending from the engaging portion 21. The first fixation has a structure in which the arm portion 22 is interposed between the electric wire 7 and the tongue piece 11 (in this example, the first tongue piece 11a). With this configuration, it is possible to fix the first tongue piece 11a of the wire protection material 8 by wrapping it around the arm portion 22 of the first fixing member 20a. Therefore, the wire protection material 8 can be firmly attached to the electric wire 7.

[0053] (6) The tongue 11 (in this example, the first tongue 11a) is formed in a shape that makes surface contact with the arm portion 22. With this configuration, the surface when the first tongue 11a is placed against the arm portion 22 is flat, so the first tongue 11a is less likely to shift position. This makes it possible to make the wire protection material 8 less likely to shift position after attachment to the electric wire installation location 2. Also, since it is possible to ensure a wide contact area between the first tongue 11a of the wire protection material 8 and the first fixing member 20a, the wire protection material 8 can be firmly pressed against the first fixing member 20a.

[0054] (7) The fixing member 20 (first fixing member 20a in this example) has an arm 22 on only one side of the engaging portion 21. The electric wire 7, tongue 11 (first tongue 11a in this example), and arm 22 are arranged in an aligned manner such that axes P1 to P3 are aligned in the stacking direction. With this configuration, the electric wire 7, first tongue 11a, and arm 22 can be arranged in a stacked manner, so that this portion can be compactly organized.

[0055] (8) The protection material main body 10 has flexibility. With this configuration, when the wire protection material 8 is disposed at the electric wire installation location 2, it is less affected by the shape of the electric wire installation location 2. This is advantageous for disposing the wire protection material 8 at the electric wire installation location 2 without any gaps.

[0056] (9) The protective material body 10 has a displacement allowing portion 27 that prevents the electric wire 7 from protruding from the protective material body 10 even if the electric wire 7 moves in the planar direction of the protective material body 10. With this configuration, even if the electric wire 7 is displaced in the planar direction (left-right direction) of the protective material body 10 when the electric wire 7 is assembled or when the electric wire 7 vibrates, the electric wire 7 is less likely to protrude from the wire protective material 8. Therefore, the electric wire 7 can be suitably protected.
