First, the embodiments of the present disclosure are listed and described.
[1] The wire protection material of the present disclosure is configured to protect the outer peripheral surface of the wire routed to the wire routing location, and is interposed between the interference portion existing at the wire routing location and the wire. A main body of the protective material is formed in a plane shape.

According to this configuration, since the protective material main body of the wire protective material is planar, the wire protective material can be bent. As a result, the wire protection member can be arranged along the shape of the wire routing location. Therefore, even when the outer peripheral surface of the wire is protected by the wire protective material, the wire does not have linear rigidity, and the wire can be arranged along with the wire protective material along the shape of the wire routing location. becomes possible. Therefore, it is possible to improve the easiness of wiring of electric wires.

[2] The wire protection member has tongues provided at least one of both ends in the length direction of the protection member body. The tongue is fixed to the electric wire by a first fixation in which a fixing member for fixing the electric wire is interposed between the electric wire and the electric wire, a second fixation in which the fixing member is not interposed, or a combination thereof. is assembled to. According to this configuration, it is possible to assemble the wire protection member to the electric wire using an appropriate and optimal fixing method among the first fixation, the second fixation, and a combination thereof, depending on the shape of the wire routing location. It becomes possible. Therefore, it contributes more to the improvement of the ease of wiring of an electric wire.

[3] The first fixation is a structure in which the tongue is brought into contact with the fixation member attached and fixed to the electric wire. According to this configuration, the wires are integrally assembled with the fixing member, and the wire protection member is fixed to the assembly, so that the structure of the first fixing can be a structure with a plurality of fixing points. Therefore, it becomes possible to firmly fix the electric wire, the electric wire protection member, and the fixing member. In addition, since the tongue piece is fixed on the basis of the fixing member attached and fixed to the electric wire, it is possible to position the electric wire protection member with respect to the electric wire.

[4] The first fixation and the second fixation are structures in which a tape member is wound around and the tongue piece is attached to the electric wire. According to this configuration, the wire protection member can be fixed to the wire by a simple method using a tape member.

[5] The fixing member has an engaging portion that engages with the wire routing portion, and an arm portion that extends from the engaging portion. The first fixation is a structure in which the arm is interposed between the electric wire and the tongue. According to this configuration, it is possible to fix the tongue piece of the wire protection member by tying it to the arm portion of the fixing member. Therefore, it is possible to firmly attach the wire protection member to the wire.

[6] The tongue is formed in a shape that makes surface contact with the arm. According to this configuration, since the surface of the tongue when it is brought into contact with the arm is a flat surface, the tongue is less likely to be displaced. Therefore, it is possible to make it difficult for the wire protective member to be displaced after being attached to the wire routing location. In addition, since it is possible to secure a large contact area between the tongue of the wire protective member and the fixing member, it is possible to firmly press the wire protective member against the fixing member.

[7] The fixing member has a shape having the arm portion only on one side with respect to the engaging portion. The electric wire, the tongue piece, and the arm portion are arranged so that their axes are aligned in the stacking direction. According to this configuration, the electric wires, tongues, and arms can be arranged so as to be piled up, so that this portion can be compactly assembled.

[8] The protective material main body has flexibility. According to this configuration, when the wire protection member is arranged at the wire routing location, it is less likely to be affected by the shape of the wire routing location. Therefore, it is advantageous in arranging the wire protection member without gaps at the wire routing location.

[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 when the electric wire moves in the planar direction of the protective material main body. According to this configuration, even if the electric wire is displaced in the plane direction of the protective member main body when the electric wire is assembled or vibrates, the electric wire is less likely to protrude from the electric wire protective member. Therefore, it is possible to suitably protect the electric wire.

[10] The wire harness of the present disclosure includes electric wires routed to a wire routing location, a fixing member that fixes the wires to the wire routing location, and a wire protection material that protects the outer peripheral surface of the wires. The wire protection member has a planar protection member main body interposed between the wire and an interference portion existing at the wire routing location.

According to this configuration, it is possible to obtain the same effect as that of the wire protection material. Therefore, it is possible to improve the easiness of wiring of electric wires and, by extension, wire harnesses.
[11] At least a portion of the outer peripheral surface of the electric wire, where the electric wire protective material is laid, is provided with a bendable protective layer capable of bending together with the electric wire while protecting the electric wire. According to this configuration, even when the electric wire is bent and arranged, the outer peripheral surface of the electric wire can be suitably protected.

[12] A hard protective layer having rigidity is provided on at least a portion of the outer peripheral surface of the electric wire where a user steps on it. According to this configuration, the portion of the outer peripheral surface of the electric wire that is frequently stepped on by the user is protected by the hard protective layer having rigidity, so that the electric wire can be more preferably protected.

[13] The wire protection member has tongues provided at least one of both ends in the length direction of the protection member body. The tongue is fixed to the electric wire by a first fixation in which a fixing member for fixing the electric wire is interposed between the electric wire and the electric wire, a second fixation in which the fixing member is not interposed, or a combination thereof. is assembled to. According to this configuration, the same effect as that of the wire protection member can be obtained.

[14] The fixing member has an engaging portion that engages with the wire routing portion, and an arm portion that extends only to one side from the engaging portion. The first fixing is a structure in which the arm portion is interposed between the electric wire and the tongue piece to fix the electric wire protective member to the electric wire. According to this configuration, it is possible to position the wire protective member with respect to the electric wire by fixing the tongue piece of the wire protective member with reference to the arm portion of the fixing member.

[15] The fixing member includes a first fixing member that participates in assembling the wire protecting member to the electric wire, and a second fixing member that does not participate in assembling the wire protecting member to the electric wire. The second fixing member has an engaging portion engaged with the wire routing portion and a pair of arm portions extending to both sides from the engaging portion, and the pair of arm portions are directly attached to the wire. Fixed. According to this configuration, the arrangement position of the second fixing member is not affected by the wire protection member. As a result, the second fixing member can be arranged at an optimum position because the second fixing member can be arranged freely.

The bendable protective layer 16 is, for example, a sheet material and is wound around the wire body 14 . In this example, the bendable protective layer 16 is formed to have the same or substantially the same length as the protective material main body 10 .

It is preferable that the wire body 14 is wrapped with a tape 17 having no protective function, and a hard protective layer 15 and a bendable protective layer 16 are provided on the outer side of the tape 17 . Therefore, the tape 17 is exposed to the outside at a portion of the wire 7 (wire body 14) where the hard protective layer 15 and the bendable protective layer 16 are not provided. Note that the tape 17 is not limited to being provided over the entire surface of the electric wire body 14 , and may be omitted from the bendable protective layer 16 , for example.

[Overview of Fixing Wire Harness 1 to Wire Routing Location 2]
As shown in FIG. 1 , the wire harness 1 is attached and fixed to the wire routing location 2 by two fixing members 20 . In the case of this example, the wire harness 1 is fixed to the wire wiring location 2 at two locations, the floor surface 3 and the standing wall 4 . The fixing member 20 used for fixing on the standing wall 4 is referred to as "first fixing member 20a", and the one used for fixing on the floor surface 3 is referred to as "second fixing member 20b". The fixing member 20 is a so-called clamp.

The first fixing member 20a has an engaging portion 21 that engages with the wire routing portion 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 sleeve clamp". The second fixing member 20b has an engaging portion 23 to be engaged with the wire routing portion 2 and a pair of arm portions 24 extending from the engaging portion 23 to both sides. The second fixing member 20b is a so-called "both sleeve clamp". Further, in the case of this example, the first fixing member 20a is involved in assembling the wire protection member 8 to the wire 7, and the second fixing member 20b is not involved.

[Overview of Fixing Wire Protective Material 8 to Wire 7]
As shown in FIGS. 4 and 5, the tongue piece 11 has a first fixing member 20 interposed between the wire 7 and the wire 7, and a second fixing member 20 without the fixing member 20 interposed. 2, or a combination thereof. In the present case, a first fixation is used for the first tongue 11a and a second fixation is used for the second tongue 11b. That is, the first tongue piece 11a is fixed to the wire 7 with the first fixing member 20a interposed therebetween. On the other hand, the second tongue piece 11b is directly fixed to the electric wire 7 without the second fixing member 20b.

The first fixation is a structure in which the tongue 11 (first tongue 11a) is brought into contact with the fixing member 20 (first fixing member 20a) attached and fixed to the electric wire 7 and fixed. Specifically, first, the electric wire 7 and the first fixing member 20a are fixed by tape winding, and the first tongue piece 11a of the wire protection member 8 is fixed to this assembly.

The first fixation and the second fixation are structures in which the tape member 26 (26a, 26b) is wound around and the tongue piece is assembled to the electric wire. Specifically, the first fixation is, for example, an assembly in which the electric wire 7 is placed on the arm portion 22 of the first fixing member 20a, and the arm of the first fixing member 20a is fixed by the electric wire 7 and the first tongue 11a. By wrapping the periphery with the tape member 26a while holding the portion 22 therebetween, these are assembled integrally. Therefore, the electric wire 7, the first tongue piece 11a, and the arm portion 22 are integrally fixed by winding the tape member 26a around the arm portion 22 positioned between the electric wire 7 and the first tongue piece 11a. there is Thus, the first fixation is a structure in which the wire protection member 8 is fixed to the wire 7 by interposing the arm portion 22 between the wire 7 and the first tongue piece 11a. In the second fixation, for example, the electric wire 7 is put on the second tongue piece 11b, and these are wrapped around by the tape member 26b, so that they are integrally assembled.

The protective material main body 10 has a displacement permitting portion 27 that prevents the electric wire 7 from protruding from the protective material main body 10 even if it moves in the plane direction of the protective material main body 10 . In the case of this example, the displacement-allowing portions 27 are provided on both sides in the width direction of the protective material main body 10 . Further, the displacement-allowing portion 27 is a sheet portion integrated with the protective material main body 10 .

A pair of arm portions 24 of the second fixing member 20 b are directly fixed to the electric wire 7 . In the case of this example, the second fixing member 20b is integrally fixed to the electric wire 7 by winding the pair of arm portions 24 around the electric wire 7 with a tape 28, respectively.

As shown in FIG. 6, the first tongue piece 11a is shaped to come into surface contact with the arm portion 22 of the first fixing member 20a. As a result, the first tongue piece 11 a can be placed on the plane of the arm portion 22 instead of directly contacting the outer circumference (curved surface) of the electric wire 7 . The electric wire 7, the first tongue piece 11a, and the arm portion 22 are aligned so that the axes P are aligned in the stacking direction (the Z-axis direction in FIG. 6). That is, when 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 portion 22 is P3, the axes P1 to P3 are vertically aligned. are arranged as follows.

[Action]
Next, the action of the wire protection member 8 (wire harness 1) of this embodiment will be described.
As shown in FIG. 7, in the case of this example, since the wire protective material 8 is plate-shaped (planar), when the wire harness 1 is shipped, the wire harness 1 is folded at the wire protective material 8 and packed. becomes possible. Therefore, the wire harness 1 can be compactly accommodated in an approximately U-letter shape, which facilitates handling during transportation.

As shown in FIG. 8, when the wire harness 1 is attached to the wire routing location 2, the wire harness 1 is taken out from the package, the wires 7 that have fallen down are raised, and the wire harness 1 is formed into a substantially letter L shape. to Then, the engaging portion 21 of the first fixing member 20 a is engaged with the engaged portion 30 (shown in FIG. 9 ) of the upright wall 4 , and the engaging portion 23 of the second fixing member 20 b It engages with the engaged portion 31 (shown in FIG. 1). In this example, the engaged portion 30 is, for example, a recess (hole). Also, the engaged portion 31 is a recess (hole) provided in a pedestal 32 (shown in FIG. 1) of the floor surface 3 .

As shown in FIG. 9, since the wire protection member 8 is bound and fixed to the first fixing member 20a by the tape member 26a, when the first fixing member 20a is fixed to the engaged portion 30, the first fixing member It becomes possible to press the wire protection member 8 in the mounting direction of 20a (direction of arrow A in FIG. 9). That is, it is possible to arrange the wire protection member 8 along the wire routing portion 2 with a small gap.

As shown in FIG. 10 , even if the wire harness 1 has an excess length, the excess length can be absorbed by adjusting the bending angle of the wire protection member 8 . That is, when the wire harness 1 has an excess length, when the wire harness 1 is pushed in by the excess length, the wire protection member 8 is bent so as to be pushed in accordingly, and the wire harness 1 is positioned at the wire routing portion 2. It is possible to arrange them along. Further, the height H of the wire harness 1 is the thickness of the wire main body 14 , the surrounding protective layers (the hard protective layer 15 and the bendable protective layer 16 ), and the thickness of the wire protective material 8 . Therefore, the height H of the wire harness 1 can also be kept low.

As shown in FIG. 11, when the position of the wire harness 1 is adjusted during assembly of the wire harness 1 or when the vehicle vibrates, the wires 7 move left and right along the planar direction of the wire protection member 8 (in the direction of arrow B1 in the figure). or B2 direction). In the case of this example, since the displacement-allowing portions 27 are provided on both sides of the protective material main body 10, even if the electric wire 7 swings left and right, the electric wire 7 can be maintained on the electric wire protective material 8. becomes. Therefore, it is possible to make it difficult for the electric wire 7 to be damaged.

According to the wire protection member 8 (wire harness 1) of the above embodiment, the following effects can be obtained.

According to this configuration, since the protective material main body 10 of the wire protective material 8 is made flat, the wire protective material 8 can be bent. As a result, the wire protection member 8 can be arranged along the shape of the wire routing location 2 . Therefore, even when the wire protective member 8 protects the outer peripheral surface of the wire 7, the wire 7 does not have linear rigidity, and the wire 7 is formed into the shape of the wire routing portion 2 together with the wire protective member 8. It is possible to arrange them along. Therefore, it is possible to improve the ease of routing the wires 7 .

Therefore, the electric wire 7, the wire protection member 8, and the fixing member 20 can be firmly fixed. In addition, since the tongue piece 11 is fixed with reference to the fixing member 20 attached and fixed to the electric wire 7 , the wire protection member 8 can be positioned with respect to the electric wire 7 .

(4) The first fixation and the second fixation are structures in which the tape member 26 is wound around and the tongue piece 11 is attached to the electric wire. With this configuration, the wire protection member 8 can be fixed to the wires 7 by a simple method using the tape member 26 .

The first fixation is 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). According to this configuration, the first tongue piece 11a of the wire protection member 8 can be tied and fixed to the arm portion 22 of the first fixing member 20a. Therefore, the wire protection member 8 can be firmly attached to the wire 7 .

(6) The tongue piece 11 (first tongue piece 11a in this example) is formed into a shape that makes surface contact with the arm portion 22 . According to this configuration, since the surface of the first tongue piece 11a that is brought into contact with the arm portion 22 is a flat surface, the first tongue piece 11a is less likely to be misaligned. Therefore, it is possible to make it difficult for the wire protection member 8 to be displaced after being attached to the wire routing location 2 . In addition, since the contact area between the first tongue 11a of the wire protection member 8 and the first fixing member 20a can be widened, the wire protection member 8 should be firmly pressed against the first fixing member 20a. can also

(7) The fixing member 20 (first fixing member 20 a in this example) has a shape having an arm portion 22 only on one side of the engaging portion 21 . The wires 7, the tongues 11 (first tongues 11a in this example), and the arms 22 are arranged so that the axes P1 to P3 are aligned in the stacking direction. According to this configuration, the electric wire 7, the first tongue piece 11a, and the arm portion 22 can be arranged so as to be piled up, so that this portion can be made compact.

(8) The protective material main body 10 has flexibility. According to this configuration, when the wire protection member 8 is arranged at the wire routing location 2 , it is less likely to be affected by the shape of the wire routing location 2 . Therefore, it is advantageous for arranging the wire protection member 8 in the wire routing location 2 without any gap.

(9) The protective material main body 10 has a displacement-allowing portion 27 that prevents the wire 7 from protruding from the protective material main body 10 even if it moves in the plane direction of the protective material main body 10 . According to this configuration, even if the electric wire 7 is displaced in the plane direction (horizontal direction) of the protective material main body 10 when the electric wire 7 is assembled or vibrates, the electric wire 7 protrudes from the electric wire protective member 8. it gets harder. Therefore, the electric wire 7 can be suitably protected.

(11) A hard protective layer 15 having rigidity is provided on at least a portion of the outer peripheral surface of the electric wire 7 where the user steps on it. According to this configuration, since the portion of the outer peripheral surface of the electric wire 7 that is frequently stepped on by the user is protected by the hard protective layer 15 having rigidity, the electric wire 7 can be protected more preferably.

(12) The fixing member 20 includes a first fixing member 20a involved in attaching the wire protecting member 8 to the wire 7 and a second fixing member 20b not involved in attaching the wire protecting member 8 to the wire 7. The second fixing member 20 b has an engaging portion 23 engaged with the wire routing portion 2 and a pair of arm portions 24 extending to both sides from the engaging portion 23 . fixed directly. With this configuration, the arrangement position of the second fixing member 20 b is not affected by the wire protection member 8 .
