Description

The present invention relates to a protector for a wire harness arranged in a vehicle, and in particular to reasonably inserted into the protector the group of harnesses that are united as previously subharnesses every electrical component system.

  Wire harnesses that are routed in automobiles can be installed by attaching box-shaped protectors molded with synthetic resin to required locations such as locations that have interference in the routing route, locations that need to be bent into a predetermined shape, etc. Protects the wires and keeps them bent.

  As shown in FIG. 14, this type of protector 1 connects a bowl-shaped main body 2 and a lid 3 via hinges 4, and fixing pieces 5 extend from the bottom wall 2 a at both ends in the longitudinal direction of the main body 2. The protector 1 is attached and fixed to the wire harness W by tape-fixing the wire harness W inserted through the main body 2 to the fixing piece 5, and then the cover 3 is rotated and covered to lock the main body 2. Are connected. Alternatively, the main body 2 and the lid body 2 are formed separately, and after the wire harness is inserted through the main body, the lid body is attached and locked.

  On the other hand, with the increase in the number of automobile systems, the number of wire harness circuits (number of electric wires) arranged in the automobile is also increasing. In the manufacturing process of the wire harness having a large amount of wires as described above, from the viewpoint of management in the work process, etc., as shown in FIG. 14, the wire harness W is previously set as a sub-harness Wa, Wb... For each electrical component system. Are tied to the connector. The plurality of sub-harnesses Wa, Wb... Are combined into one wire harness W. Therefore, even when the protector 1 is attached to a required portion of the wire harness W, the divided sub-harnesses Wa, Wb... Are sequentially assembled into the protector 1 and finally closed with the lid 3.

However, when the amount of the electric wire inserted into the protector 1 is large, the electric wire w protrudes when the lid 3 is closed, and there is a problem that the electric wire w is damaged by being sandwiched between the lid 3 and the main body 2. Moreover, when the operation | work which pushes the electric wire w which protruded into the protector 1 again is needed, it will be necessary to cancel | release a lock | rock using a jig | tool etc., and workability | operativity will worsen. In addition, there is a problem that the work efficiency is remarkably lowered, such as the electric wire w once incorporated in the protector 1 sticks out of the protector or pushes up the lid 3 due to staking or the like.
Furthermore, it is conceivable that the sub-harnesses Wa and Wb are tightly or roughly wound with tape so that the electric wires w do not protrude apart, but the workability is poor and the cost is high.

  Japanese Patent Laid-Open No. 11-299047 (Patent Document 1) proposes a protector shown in FIG. The protector 1 ′ is configured such that when the lid 3 ′ is closed after the wire harness W ′ is inserted into the protector body 2 ′ having a U-shaped cross section, the body rib 2 ′ is formed on the lid 3 ′ by the falling rib 6 ′. The harness pressing portion 7 'provided on the side wall 2b' is pushed from the outside and falls inward, and the elastic pressing portion 8 'formed at the tip of the harness pressing portion 7' connects the wire harness W 'to the protector body 2'. It is firmly pressed and held.

  The protector 1 ′ can push the wire harness W ′ into the protector 1 ′ and can fix the wire harness W ′ and the protector 1 ′ with one touch only by closing the lid 3 ′. Effective only when harness W 'is tightly wound or roughly wound in a bundle with tape. When multiple bundles of sub-harnesses are incorporated, or when each sub-harness is not densely or roughly wound. The harness holding part 7 ′ cannot effectively prevent the electric wire from protruding.

Japanese Patent Laid-Open No. 11-299047

The present invention has been made in view of the above-mentioned problems, and even if a two-harness is incorporated in the protector and the wire harness increases in the amount of electric wires, it prevents the electric wires from protruding and floating up easily and reliably. It has an object to provide a can be pulp protector be incorporated into the protector.

In order to solve the above problems, a flop protector box shape composed of a protector body and lid of the trough-shaped inserting the two sub-harnesses constituting the wire harness to be mounted in vehicles,
While the two sub harness wiring harness is divided sub harnesses for each electric instrumentation systems, each sub-harness these two will be bundled with the binding band projecting from the respective locking portions,
The protector main body of the protector has a plurality of locking holes for locking the locking portions of the binding band, a boundary portion between the bottom wall and both side walls of the protector main body, or a wire harness from the boundary portion and the boundary portion. Drilled in an inclined part provided on the inner surface of the bottom wall with an interval in the width direction perpendicular to the insertion direction,
The two sub-harnesses are inserted in parallel in the width direction along the boundary between the bottom wall and both side walls of the protector main body, and the locking portion protruding from the binding band of the inserted sub-harness is provided in the protector main body. in a state where the insertion and engaged with the locking hole provided in the front Kifuta provides a protector for a wire harness insertion are those attached to the protector body.

  Thus, each sub harness which comprises a wire harness is inserted in a protector in the state bundled with the binding band, and can be accommodated in a protector, without disturbing the electric wire of each sub harness. And since the accommodated subharness is fixed in a protector using a binding band, the subharness to insert next can also be smoothly inserted in a protector. By repeating this sequentially, a plurality of sub-harnesses can be accommodated in the protector in an orderly manner without the electric wires being entangled in the protector. As a result, it is possible to prevent the electric wire of the sub harness from protruding from the protector, and to prevent the electric wire from being lifted by the electric wire, and the lid from being pushed up. Therefore, a plurality of sub-harnesses grouped for each electrical component system are accommodated in the protector, and even when the amount of electric wires inserted into the protector increases, the protector can be easily and reliably inserted into the protector. It is possible to prevent electric wire damage caused by pinching the electric wire between them.

  In addition, work such as pushing in the electric wire protruding outside the protector is unnecessary, and workability is improved. In addition, the binding band with a locking part that locks and fixes the wire harness to the protector body is attached when it is formed as a sub-barness for each electrical system in the wire harness manufacturing process, so the sub-harness itself can be easily managed. Thus, it does not become a burden at the time of passing the wire harness through the protector.

As described above , the locking hole that inserts and locks the locking portion of the binding band that binds the sub-harnesses of the wire harness, the boundary portion between the bottom wall and the side walls of the protector body, or the boundary portion And in the inclined portion provided on the inner surface of the bottom wall with an interval in the width direction orthogonal to the wire harness insertion direction from the boundary portion,
The locking portion of the binding band that binds the sub-harnesses constituting the wire harness is inserted and locked in the locking hole of the protector body, and along the boundary between the bottom wall and both side walls inside the protector body. The sub-harness is inserted in parallel to the width direction.
That is, when the protector main body has a U-shaped cross section without providing the inclined portion as described above, it is easy to create a dead space between the corners in the width direction of the bottom wall of the protector main body and the harness. By providing the inclined portions at both corners in the width direction, the locking portion can be projected from the inclined portion to the dead space portion, and the space can be used effectively.
Moreover, not only the said boundary part but if an inclined part is provided also in the bottom wall inner surface at intervals in the width direction from a boundary part, three or more sub harnesses can be accommodated in a protector orderly.

Further, the present invention is a box-shaped protector comprising a saddle-shaped protector body and a lid through which two sub-harnesses constituting a wire harness routed in an automobile are inserted,
The two sub-harnesses of the wire harness are sub-harnesses divided for each electrical system, and each of the two sub-harnesses is bound by a binding band having a locking portion protruding,
The protector body of the protector is provided with a plurality of locking holes for locking the locking portions of the binding band, respectively, inclined from the inner surfaces of both side walls of the protector body to the bottom wall or to the bottom wall side. It is drilled in the support piece,
The two sub-harnesses are inserted in parallel in the width direction along the boundary between the bottom wall and both side walls of the protector main body, and the locking portion protruding from the binding band of the inserted sub-harness is provided in the protector main body. A protector for inserting a wire harness is provided in which the lid is attached to the protector main body in a state where the lid is inserted and locked in the locking hole.
Between the front Symbol support piece and the bottom wall is provided with a housing space of the engagement portion provided in the binding band.
In this case, the protruding portion of the locking portion is also accommodated in the protector, and the protector outer surface has a simple shape without protrusions or catches, so that interference with other in-vehicle components can be prevented as much as possible.

  The support piece preferably has flexibility. As a result, the support piece bends downward or tilts due to the weight or pressing of the sub-harness after the sub-harness is inserted, and the locking portion protrudes into the dead space at both corners of the bottom wall. Sinks down. Therefore, the space in the protector body can be used effectively, and a large number of electric wires can be accommodated by one protector.

The plurality of fixed surface fastener tapes that are adhesively fixed to the protector body are color-coded, and the plurality of bundled surface fastener tapes that bundle the sub-harnesses correspond to the colors of the fixed surface fastener tapes of the mating counterparts. It is preferable to be color-coded.
Alternatively, the plurality of fixed surface fastener tapes bonded and fixed to the protector main body are color-coded by applying a color tape or applying paint in the vicinity thereof, and the plurality of binding surface fastener tapes for bundling the sub-harnesses May be color-coded into a color corresponding to the color of the color tape or paint applied in the vicinity of the fixed hook-and-loop fastener tape to be locked.

The binding surface fastener tape may be color-coded according to the fixing position in the protector of each sub-harness bundled by the binding surface fastener tape.
Alternatively, the bundling surface fastener tape may be color-coded by applying a color tape or applying paint in the vicinity thereof depending on the fixing position of each sub-harness bundled by the bundling surface fastener tape in the protector.

  Thereby, the optimal insertion position according to the connection destination etc. of each sub harness can be discriminate | determined easily and reliably. Alternatively, when there are sub-harnesses that cannot be contacted and locked directly to the fixed surface fastener tape fixed in the protector body due to the large number of sub-harnesses, the fixing position of each sub-harness and each sub-harness It is possible to lock and fix the sub-harness to the hook-and-loop fastener tape that binds adjacent sub-harnesses by determining the male and female of the hook-and-loop fastener locking pieces.

As described above, according to the protector for a wire harness insertion of the present invention, the two sub harnesses being focused on each of the electrical system is inserted into the protector, when the wire volume increases, the protector Because each sub-harness can be locked and fixed sequentially and easily near the bottom wall, even if multiple sub-harnesses are inserted and the total amount of electric wires increases, it is impossible to force each sub-harness. Instead, they can be inserted into the protector sequentially and wired in parallel. In addition, the wire can be prevented from protruding or lifting due to the brazing of the wire, and the wire can be prevented from being damaged by being caught between the protector body and the lid. improves.

  In addition, the present invention utilizes the fact that it is divided into a plurality of sub-harnesses for each electrical system in advance in the manufacturing process of the wire harness, and is bundled with a binding band for each sub-harness. This eliminates the need for work to be performed and enables efficient work.

Furthermore, before Kipu protector is an inclined portion between the bottom wall and both side walls of the protector body is provided, by providing a locking hole in the inclined portion, it is possible to project the engaging portion in the dead space, Space can be used effectively.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a protector for use in the insertion method and the method of the protector 20 of the wire harness 10 according to the reference first embodiment of the present invention.
The wire harness 10 is composed of a group of wires that are separately connected to two electrical systems. In the manufacturing process, as shown in FIG. 1, each electrical system is provided in advance as sub-harnesses 10A and 10B. Bundling bands 11A and 11B are wound around the insertion positions of the sub-harnesses 10A and 10B into the protector 20 at two positions on the front and rear, respectively.

  As shown in FIGS. 1 and 2, the binding bands 11A and 11B are wound around the band portions 12A and 12B that are wound around the sub-harnesses 10A and 10B and fastened to locking holes 28A and 28B of the protector main body 21 described later. The locking portions 13A and 13B to be inserted and locked are integrally formed of resin. The locking portion 13A (13B) includes a shaft portion 14A (14B) erected from the band portion 12A (12B), and a blade portion 15A (15B) formed by folding the tip of the shaft portion 14A (14B) left and right. Become.

  The protector 20 has a box shape integrally formed of resin. Specifically, a main body 21 having a U-shaped cross section having a bottom wall 22 and both side walls 23a and 23b and a lid 24 for closing the upper opening of the main body 21 are connected to one end side via a hinge 25. The other end side is connected to the lock part 26 and the locked part 27 so as to be freely opened and closed.

  The bottom wall 22 of the main body 21 is provided with two locking holes 28A and 28B for inserting and locking the blade portion 15 of the locking portion 13. Specifically, as shown in FIG. 1, the locking hole 28A is drilled at an interval on the line L1 in the wire harness insertion direction, and the locking hole 28B is on a different line L2 parallel to the line L1. These holes are formed at two positions shifted in the longitudinal direction from the locking holes 28A. Moreover, the fixed piece 29 is extended to the bottom wall 22 from the both ends of a wire harness insertion direction.

  The operation of inserting the wire harness 10 into the protector 20 having the above-described configuration is as follows. First, the sub-harness 10A is inserted into the protector main body 21, and the locking portions 13A of the two binding bands 11A attached to the sub-harness 10A are attached to the main body 21. It is inserted and locked in the two locking holes 28A drilled in the bottom wall 22. Next, the sub-harness 10B is inserted into the main body 21, and the locking portions 13B of the two binding bands 11B attached to the sub-harness 10B are inserted and locked into the locking holes 28B of the main body 21. Finally, as shown in FIG. 3, after the wire harness 10 and the fixed piece 29 are wound and fixed with the tape T, the lid 24 is closed to close the upper surface of the protector body 21, and the lock portion 26 and the locked portion At 27, the lock is closed.

When the protector 20 is used and the wire harness 10 including a plurality of sub-harnesses is inserted into the protector 20 , the wire harness 10 is firmly attached to the bottom side in the protector body 21 in a state of being bundled for each of the sub-harnesses 10A and 10B. Even when the lid 24 is closed, the gap between the lid 24 and each of the sub-harnesses 10A and 10B can be secured, so that the wires may be scattered and protrude outside the protector 20, or the lifted wires may be covered with the lid. 24 can be prevented from being pushed up, and the electric wire can be prevented from being damaged by sandwiching the electric wire between the lid 24 and the main body 21. Furthermore, since the push-back operation of the protruding electric wire becomes unnecessary, the binding for each sub-harness 10A, 10B is performed on the sub-harness 10A, 10B formed in advance for each electrical system in the wire harness manufacturing process. The work of specially dividing the wire harness is not necessary, and the workability is improved.

Further, since the two sub-harnesses 10A and 10B are respectively fixed on the one line L1 and the one line L2 in the protector body 21 and are inserted in parallel to each other in the width direction of the protector 20, the sub-harnesses are connected to each other in the protector 20. Can be prevented from interfering with each other.
Furthermore, the portion around which the binding bands 11A and 11B of the sub-harnesses 10A and 10B are wound is thicker than the other portions, but the locking hole 28A for fixing the sub-harness 10A and the locking hole for fixing the sub-harness 10B. 28B, the positions of the binding band 11A of the sub-harness 10A and the position of the binding band 11B of the sub-harness 10B are overlapped at the same position in the longitudinal direction. Can be avoided. Thereby, the sub harness 10A and the sub harness 10B can be inserted as close as possible, and more electric wires can be routed in the protector 20 with high density.

4 and 5 show a second embodiment of the present invention. In this embodiment, the shape of the protector is different from the shape of the protector in the first reference embodiment.
An inclined portion 30 (30A, 30B) is provided at the boundary between the bottom wall 22 and both side walls 23a, 23b of the protector 20, and the sub harnesses 10A, 10B are fixed to the inclined portion 30. Since other configurations are the first embodiment and the same configuration reference, its description is omitted with the same reference numerals.

Two inclined portions 30 </ b> B are also provided at the boundary portion with an interval in the longitudinal direction.
The inclined portion 30 (30A, 30B) includes a quadrangular inclined wall 30a provided in parallel with the longitudinal direction and two triangular supporting walls 30b provided in a direction orthogonal to the longitudinal direction. The wall 22 and the side walls 23a, 23b are projected continuously and integrally so as to protrude inward.
The bottom wall 22 and the side walls 23a and 23b are not provided on the outer surface side of the inclined portion 30, and the inclined portion 30 is exposed to the outside.

  A locking hole 31A is formed in the inclined wall 30a of the inclined portion 30A, and the locking portion 13A of the binding band 11A attached to the sub-harness 10A is inserted and locked into the locking hole 31A.

Further, the inclined wall 30a of the inclined portion 30B is provided with a locking hole 31B, and the locking portion 13B of the binding band 11B attached to the sub harness 10B is inserted and locked into the locking hole 31B. The harness 10B is fixed in the protector body 21.

  In this embodiment, as shown in FIG. 5 (A), the locking portions 13A and 13B protrude obliquely outward from the inclined wall 30a. This protruding space is also shown in FIG. 5 (B). The dead space S1 formed between the sub-harnesses 10A, 10B, the bottom wall 22, and the side walls 23a, 23b when the protector body 21 is not provided with the inclined portion 30 is limited in the vehicle. Can be used effectively.

  Further, as shown in FIG. 6, the bottom wall is spaced from the inclined portions 30A and 30B provided at the boundary between the bottom wall 22 and the side walls 23a and 23b of the protector 20 in the width direction orthogonal to the wire harness insertion direction. The inclined portions 30 </ b> C, 30 </ b> D, and 30 </ b> E may be provided on the inner surface of 22. The inclined portions 30C, 30D, and 30E are composed of an inclined wall 30a and two support walls 30b, and project continuously and integrally from the bottom wall 22 in the same manner as the inclined portions 30A and 30B. Locking portions 13C, 13D, and 11E of the binding bands 11C, 11D, and 11E attached to the sub-harnesses 10C, 10D, and 10E also in the locking holes 31C, 31D, and 31E formed in the inclined walls 30a of the inclined portions 30C, 30D, and 30E, 13E is inserted and locked, and the sub-harnesses 10A to 10E are fixed in the protector body 21. Note that the number of inclined portions provided on the inner surface of the bottom wall is not limited to three, and may be one, two, or four or more.

7 and 8 show a third embodiment of the present invention. Third embodiment is the shape of the protector the reference first embodiment, is different from the second embodiment. In the present embodiment, support pieces 40A, 40B having flexibility are projected from both side walls 23a, 23b of the protector body 21, and the sub harnesses 10A, 10B are fixed to the support pieces 40. Since other configurations are the first embodiment and the same configuration reference, its description is omitted with the same reference numerals.

  The support pieces 40 </ b> A and 40 </ b> B are provided in two places at intervals in the longitudinal direction of the protector body 21. The support piece 40A protrudes in parallel with the bottom wall 22 from the inner surface of the side wall 23a on the hinge 25 side at a position above the bottom wall 22, and the support piece 40B is the bottom wall of the side wall 23b on the lock 27 side. From the inner surface at a position above the required dimension from 22, it projects in parallel with the bottom wall 22.

  A locking hole 41A is formed in the support piece 40A, and a locking portion 13A of a binding band 11A attached to the sub-harness 10A is inserted and locked in the locking hole 41A, so that the sub-harness 10A is secured to the protector body 21. It is fixed inside. Further, a locking hole 41B is formed in the support piece 40B, and the locking portion 13B of the binding band 11B attached to the sub-harness 10B is inserted and locked in the locking hole 41B, so that the sub-harness 10B is protected. It is fixed in the main body 21.

  In the present embodiment, as shown in FIG. 8A, there is a space S2 between the support pieces 40A, 40B and the bottom wall 22, and the locking portion 13A for fixing the sub-harness 10A and the sub-harness 10B are fixed. The engaging portion 13B to be accommodated is accommodated in the space S2. Therefore, since the locking portions 13A and 13B do not protrude outside the protector 20, the outer shape of the protector 20 has a simple shape with no protrusions, and interference with other in-vehicle components can be suppressed as much as possible.

  Further, since the support pieces 40A and 40B have flexibility, when the sub-harnesses 10A and 10B are fixed, they are bent downward due to their weights, pressing from above, etc., and the tip is pushed down. As shown in (B), as a result, the support pieces 40A and 40B are inclined downward. As a result, the locking portions 13A and 13B project into the dead space S1 obliquely outside, and the sub-harnesses 10A and 10B themselves sink downward, so that a large space can be secured above the protector body 21. More electric wires can be accommodated.

9A and 9B show a fourth embodiment according to the present invention, and the shape of the protector is different from those of the reference first embodiment, the second embodiment, and the third embodiment. The support pieces 42A and 42B are projected from both side walls 23a and 23b of the protector body 21 so as to be inclined downward rather than parallel to the bottom wall 22, and the locking holes 43A and the support pieces 42B are engaged with the support pieces 42A. Stop holes 43B are formed respectively. In other respects, the configuration is the same as that of the third embodiment.

  In this embodiment, as shown in FIG. 9 (B), the locking portions 13A and 13B inserted and locked in the locking holes 43A and 43B do not need to be pressed down from above, and are formed in the dead space S1 diagonally outside. Therefore, when the lid 24 is closed, a large distance can always be ensured between the sub-harness 10A, 10B and the lid 24, and pinching of the electric wire can be prevented more reliably.

10 and 11 show a reference fifth embodiment.
The inner surface of the bottom wall 22 of the body 21 of the reference fifth embodiment of the flop protector 20, at two locations spaced in the longitudinal direction, continuously side walls 23a, the upper edge of 23b toward the bottom wall 22 The band-shaped fixed surface fastener tapes 50-1 and 50-2 are attached. The fixed surface fastener tapes 50-1 and 50-2 have adhesive material applied to the back surface and have male locking pieces x on the surface, and are attached to the front position in the insertion direction of the wire harness 10. The fixed surface fastener tape 50-2 attached to the rear position is colored in black, and gray in 50-1.

At the place where the sub-harness 10 </ b> A is inserted into the protector 20, the back surface is adhered to the front and back at two places spaced in the length direction corresponding to the attachment positions of the fixed surface fastener tapes 50-1 and 50-2. Bundling surface fastener tapes 51A-1 and 51A-2, which are coated with a material and have female locking pieces y on the surface, are wound and fixed to bind the sub harness 10A. Similarly, at the insertion positions of the sub-harness 10B to the protector 20, the front and rear positions corresponding to the attachment positions of the fixed surface fastener tapes 50-1 and 50-2 of the protector 20 are spaced at two positions in the front and rear. The binding surface fastener tapes 51B-1 and 51B-2 having an adhesive material applied to the back surface and the female locking pieces y on the surface are wound and fixed to bind the sub harness 10B.
Among these binding surface fastener tapes 51A-1, 51A-2, 51B-1, 51B-2, the binding surface fastener tapes 51A-1, 51B-1 wound around the front position in the wire harness insertion direction are black, The fixed surface fastener tapes 51A-2 and 51B-2 wound around the rear position are color-coded in gray.

In the operation of inserting the wire harness 10 into the protector 20 having the above-described configuration, first, the sub-harnesses 10A and 10B are sequentially inserted into the protector main body 21, and are inserted and fixed in parallel to the width direction of the protector 20. At this time, as shown in FIGS. 11A and 11B, the black fixed surface fastener tape 50-1 in the protector 20 has a black binding surface fastener tape 51A-1 attached to the subharness 10A and the subharness. The black binding surface fastener tape 51B-1 attached to 10B is locked, and the gray fixed surface fastener tape 50-2 in the protector 20 is attached to the gray binding surface fastener tape 51A-2 attached to the sub harness 10A. And the gray binding surface fastener tape 51B-2 attached to the sub-harness 10B, respectively, to bind the binding surface fastener tapes 51A-1, 51A-2, 51B-1, 51B-2 and the fixed surface fastener tape 50-1. , 50-2 are combinations of the same color.
Next, the sub-harnesses 10 </ b> A and 10 </ b> B are put together and wound around and fixed to the fixed piece 29 with the tape T, and then the lid 24 is closed and the lock portion 26 is locked to the locked portion 27.

When the wire harness 10 is tightly fixed to the bottom wall 22 side in the protector main body 21 in a state of being bundled for each of the sub-harnesses 10A and 10B by being inserted into the protector by the above method, and the lid 24 is closed. However, since a gap can be secured between the lid 24 and each of the sub-harnesses 10A and 10B, it is possible to prevent the wires from falling out of the protector 20 and pushing up the lid 24 with the lifted wires. Wire damage caused by being sandwiched between the lid 24 and the main body 21 can also be prevented.
Furthermore, since the push-back operation of the protruding electric wires becomes unnecessary, the binding for each of the sub-harnesses 10A and 10B is performed on the sub-harnesses 10A and 10B that are divided in advance for each electrical system in the wire harness manufacturing process. The work of specially dividing the wire harness is not necessary, and the workability is improved.

  Further, the locking pieces of the binding surface fastener tapes 51A-1, 51A-2, 51B-1, 51B-2 are all female locking pieces y, and the locking pieces of the fixed surface fastener tapes 50-1, 50-2. Since these are all male locking pieces x, the binding surface fastener tapes 51A-1, 51A-2, 51B-1, 51B-2 and the fixed surface fastener tapes 50-1, 50-2 are in any combination. The combination of male and female locking pieces x and y is surely made, and it is possible to securely lock and fix each other without considering the insertion position and the like.

Furthermore, the binding surface fastener tapes 51 </ b> A- 1, 51 </ b> A- 2, 51 </ b> B- 1, 51 </ b> B- 2 and the fixed surface fastener tapes 50-1, 50-2 are respectively positioned in front and rear positions in the insertion direction of the wire harness 10. Therefore, the sub-harnesses 10A and 10B can be reliably fixed in the correct insertion direction by matching the colors with each other.
Further, neither the binding surface fastener tape 51A-1 or the like nor the fixed surface fastener tape 50-1 or the like is fixed over the entire length, and is fixed only at a required portion spaced in the length direction. Therefore, workability is good and cost can be reduced.
