[Embodiment 1]
Hereinafter, the positioning structure of the flat wiring member according to the first embodiment will be described. Here, an example in which the positioning structure of the flat wiring member is a holding structure will be described. FIG. 1 is a schematic plan view showing a holding structure 10 of a flat wiring member, and FIG. 2 is a schematic cross-sectional view taken along line II-II of FIG.

The holding structure 10 of the flat wiring member is a structure for holding the flat wiring member 20 in the plate-shaped portion 12 of the vehicle.

It is assumed that the plate-shaped portion 12 (an example of the mounting target portion) in the vehicle is a part of the metal body in the vehicle, a part of the interior panel, and the like. At least one main surface of the plate-shaped portion 12 (an example of a surface to be mounted) may have a planar shape. At least a part of the flat wiring member 20 is arranged on the main surface (particularly the planar shape portion) of the plate-shaped portion 12. The width direction of the flat wiring member 20 is preferably a direction along the main surface of the plate-shaped portion 12. As a result, the flat wiring member 20 is arranged in a narrow space along the main surface direction of the plate-shaped portion 12. The present disclosure relates to a structure that holds at least a part of the flat wiring member 20 with respect to the plate-shaped portion 12. A part of the metal body or the interior panel may have an uneven shape in which grooves or protrusions are formed.

The holding structure 10 of the flat wiring member 20 includes a holding portion 14 and a flat wiring member 20.

The flat wiring member 20 is a flat wiring member including a plurality of linear transmission members. Here, the flat wiring member 20 includes a plurality of electric wires 22 and a sheet 24. The electric wire 22 is an example of a linear transmission member. The sheet 24 is an example of a member that keeps a plurality of electric wires 22 in a flat shape.

More specifically, the electric wire 22 includes a core wire and a coating. The core wire is a linear conductor formed of a conductive member such as metal. The coating is an insulating portion that surrounds the core wire. The linear transmission member may be any linear member that transmits electricity, light, or the like. For example, the linear transmission member may be a bare wire, a shielded wire, a twisted wire, an enamel wire, a nichrome wire, an optical fiber, or the like, in addition to an electric wire.

The sheet 24 is a sheet-like member that keeps a plurality of electric wires 22 in a flat shape. The sheet 24 is made of resin or the like. The sheet 24 may contain metal. The sheet 24 may include a non-woven sheet. Here, an example in which the sheet 24 has a two-layer structure is shown. For example, it is assumed that one layer is a non-woven sheet 24a and the other one layer is a resin layer 24b bonded to the non-woven sheet 24a. It is assumed that the resin layer 24b is a layer having good bonding with the coating of the electric wire 22.

The plurality of electric wires 22 are fixed in parallel on one main surface of the sheet 24. The electric wire 22 is fixed to the sheet 24 by welding, adhesion, adhesion, or the like. The welding may be ultrasonic welding or heat welding. By fixing the plurality of electric wires 22 to one main surface of the sheet 24, the plurality of electric wires 22 are kept in a flat state. By fixing the electric wires 22 to the sheet 24, the plurality of electric wires 22 are kept in a flat shape.

The flat wiring member 20 may be branched according to the position of each electrical component to be connected. Here, an example is shown in which a plurality of electric wires 22 are branched at a plurality of locations (here, three locations). In this case, the sheet 24 may be formed so as to branch along the branch path of the electric wire 22. The portion of the flat wiring member 20 provided with the largest number of electric wires 22 may be referred to as a trunk line portion. Further, the portion where the electric wire 22 branches from the trunk line portion may be referred to as a branch line portion. A cover may be attached to the seat 24 from the electric wire 22 side.

A connector 23 is attached to the end of the plurality of electric wires 22. Here, the electric wires 22 extend from the ends of the sheet 24 at both ends of the trunk line portion and at the ends of the branch line portions. A terminal is attached to the end of the electric wire 22 extending from the end of the sheet 24, and the terminal is inserted into the cavity of the connector 23. The connector may be fixed to the edge of the seat. In this case, the electric wire 22 does not have to extend from the end of the sheet 24. The flat wiring member 20 is connected to another electric device 30 or the like via a connector 23 or the like (one electric device 30 is exemplified in FIG. 1).

The flat wiring member 20 is not limited to the above example. The plurality of electric wires may be kept flat by a flat frame member or the like. A plurality of electric wires may be directly joined in a parallel form so as to have a flat form. Further, the flat wiring member 20 is a member such as an FPC (Flexible printed circuit), an FFC (Flexible Flat Cable), etc., in which a plurality of linear conductors are kept in a flat state in a state of being mutually insulated by an insulating member. There may be. That is, the flat wiring member may be a wiring member in which a plurality of linear conductors are held in a flat form in a state of being insulated from each other and formed to have a thickness smaller than the width as a whole. Further, it is not essential that the flat wiring member has a branch line portion.

The holding structure 10 is a structure that holds at least a part of the flat wiring member 20 in the extending direction as described above. In the examples shown in FIGS. 1 and 2, a part of the trunk line portion (here, two locations) is held by the holding portion 14.

The holding portion 14 protrudes from the plate-shaped portion 12 as an example. The holding portion 14 holds the flat wiring member 20 in a state where the flat wiring member 20 is placed along the main surface of the plate-shaped portion 12. The holding portion 14 is a positioning portion that positions the flat wiring member 20 in at least one direction along the main surface while the flat wiring member 20 is aligned with the main surface of the plate-shaped portion 12 which is an example of the mounting target portion. This is an example.

More specifically, the holding portion 14 is a member formed of metal, resin, or the like. The plate-shaped portion 12 and the holding portion 14 may be integrally formed members. The plate-shaped portion 12 and the holding portion 14 may be formed separately, and the holding portion 14 may be fixed to the plate-shaped portion 12. Fixation of the holding portion 14 to the plate-shaped portion 12 can be realized by various configurations including a well-known configuration. For example, the holding portion 14 may be fixed to the plate-shaped portion 12 by screwing. The holding portion 14 may be fixed to the plate-shaped portion 12 by welding, adhesion, or the like. The holding portion 14 may be fixed to the plate-shaped portion 12 by a fitting structure or the like.

The holding portion that protrudes from the plate-shaped portion 12 and holds the flat wiring member 20 includes a configuration that penetrates the flat wiring member 20 and holds the flat wiring member 20, and the flat wiring member from the side of the flat wiring member 20. It is assumed that the configuration holds 20. Here, a case where the holding portion 14 includes the former configuration, that is, an example including the penetrating holding portion 14 will be described.

The penetration holding portion 14 includes a penetration portion 15 and a retaining portion 16.

The penetrating portion 15 projects from one main surface of the plate-shaped portion 12. Here, the penetrating portion 15 has a rod shape. The penetrating portion 15 is perpendicular to one main surface of the plate-shaped portion 12.

The retaining portion 16 projects outward from the penetrating portion 15. Here, the retaining portion 16 includes a pair of retaining pieces 16a that are inclined so as to sequentially spread outward from the tip end portion of the penetrating portion 15 toward the base end side. The retaining portion may project over the entire circumference of the penetrating portion. Preferably, the retaining portion 16 can be elastically deformed toward the penetrating portion 15.

A through hole 20h is formed on the flat wiring member 20 side. Here, a through hole 20h is formed on one side of the sheet 24 in the trunk line portion. Preferably, the electric wire 22 is biased and fixed to the sheet 24 on the side away from the through hole 20h. A partially protruding portion may be formed on one side of the sheet 24, and a through hole 20h may be formed in this protruding portion.

Then, in a state where the flat wiring member 20 is stacked on the plate-shaped portion 12, the penetrating portion 15 of the penetrating holding portion 14 penetrates the through hole 20h. Then, the retaining portion 16 is caught in the retaining state with respect to the flat wiring member 20 from the opposite side of the plate-shaped portion 12 around the through hole 20h. Therefore, the flat wiring member 20 is held on one main surface of the plate-shaped portion 12. The retaining portion 16 preferably has a flat wiring member 20 sandwiched between the retaining portion 16 and the plate-shaped portion 12 so as not to move, but this is not essential.

Preferably, the diameter of the through hole 20h is smaller than the maximum width of the retaining portion 16. In this case, the penetration holding portion 14 may pull out the through hole 20h by elastically deforming the retaining portion 16 so as to narrow the width or elastically expanding the through hole 20h. it can. In order to reinforce the peripheral edge of the through hole 20h, a metal or resin eyelet may be attached to the peripheral edge of the through hole 20h.

Since the penetration holding portion 14 penetrates the flat wiring member 20, the flat wiring member 20 is held at a fixed position on the main surface of the plate-shaped portion 12. That is, the flat wiring member 20 is positioned by the penetration holding portion 14 penetrating the flat wiring member 20. In this respect, the holding structure is also a positioning structure. As shown in FIGS. 1 and 2, only one penetration holding portion 14 may be provided in the width direction of the trunk line portion of the flat wiring member 20. Even in this case, the flat wiring member 20 is held at a fixed position with respect to the plate-shaped portion 12. Here, the meaning that only one penetration holding portion 14 is provided means that a specific cross section (a cross section orthogonal to the extending direction) in the extending direction of the flat wiring member is focused on. This means that only one penetration holding portion is provided. Therefore, when different positions are viewed in the extending direction of the flat wiring member, penetration holding portions may be provided on one side and the other side of the flat wiring member. However, a plurality of penetration holding portions 14 may be provided in the width direction of the flat wiring member 20.

According to the present embodiment, the flat wiring member 20 is held against the plate-shaped portion 12 by a penetrating holding portion 14 provided so as to project from the plate-shaped portion 12. Therefore, the flat wiring member 20 is easily held with respect to the vehicle.

Further, the work of attaching the vehicle fixing parts (parts called clips or clamps) to the flat wiring member 20 is reduced or unnecessary. Therefore, the flat wiring member 20 can be easily manufactured. Further, when the flat wiring member 20 is stored and transported, the parts for fixing the vehicle are less likely to interfere with other parts, and the handleability is improved.

Since the holding portion 14 is a penetrating holding portion 14 penetrating the flat wiring member 20, the flat wiring member 20 is less likely to be displaced with respect to the plate-shaped portion 12, and the flat wiring member 20 is firmly held.

Further, even if only one through holding portion 14 is provided in the width direction of the flat wiring member 20, the flat wiring member 20 is firmly held with respect to the plate-shaped portion 12.

Various modifications on the premise of the first embodiment will be described.

In the holding structure 110 of the flat wiring member 120 according to the first modification shown in FIG. 3, the through hole 120h penetrates the intermediate portion in the width direction of the flat wiring member 20 between the plurality of electric wires 22. Here, with respect to the sheet 24, a region in which the electric wires 22 are not arranged is provided between the plurality of (two) electric wires 22. A through hole 120h is formed in this region. The penetration holding portion 14 penetrates the intermediate portion in the width direction of the flat wiring member 20 between the plurality of electric wires 22.

According to this example, the penetration holding portion 14 holds the flat wiring member 120 in a state where the electric wires 22 are arranged on both sides of the penetration holding portion 14. Therefore, both side portions of the flat wiring member 120 are held by the penetration holding portion 14 in a well-balanced manner. As a result, floating, fluttering, etc. of both side portions of the flat wiring member 120 are suppressed. This modified example can also contribute to the reduction of fixing points by the penetration holding portion 14.

In the holding structure 210 of the flat wiring member 220 according to the second modification shown in FIG. 4, the flat wiring member 220 has a configuration in which a cover 226 is added to the flat wiring member 20. The cover 226 is a cover that covers a plurality of electric wires 22. That is, the cover 226 covers the electric wire 22 from the side opposite to the seat 24. Both sides of the cover 226 are fixed to both sides of the seat 24. The cover 226 and the sheet 24 are fixed by welding, adhesion, adhesion, or the like. The welding may be ultrasonic welding or heat welding.

The cover 226 is more rigid than the seat 24. That is, the cover 226 is harder to bend than the seat 24. For example, it is conceivable that the sheet 24 is made of a non-woven sheet, and the cover is formed as a sheet in which the inside is uniformly filled with nylon, PET (polyethylene terephthalate), PP (polypropylene), or the like.

In this case, the flat wiring member 220 tends to be kept in a constant flat shape as compared with the case where the cover 226 is not provided. Therefore, the flat wiring member 220 is easily kept in a state along the main surface of the plate-shaped portion 12 by the holding portion such as the penetration holding portion 14. As a result, floating, fluttering, etc. of the flat wiring member 220 are suppressed.

Further, in this modification, a through hole 220h is formed in the cover 226. The penetration holding portion 14 penetrates the through hole 220h. Then, the retaining portion 16 is hooked on the cover 226 at the peripheral edge portion of the through hole 220h. Here, the cover 226 has a higher rigidity than the seat 24. Therefore, when a part of the cover 226 is held by the through holding portion 14, the flat wiring member 220 is easily held by the cover 226 in a state along the main surface of the plate-shaped portion 12 as a whole. Such a configuration also contributes to the reduction of the fixed portion by the penetration holding portion 14.

Preferably, the cover 226 is sandwiched between the retaining portion 16 and the plate-shaped portion 12 and regulated at a fixed position. In this case, the cover 226 is more difficult to lift from the plate-shaped portion 12.

Here, the cover 226 protrudes to the side of the seat 24, and a through hole 220h is formed in the protruding portion. A through hole may be formed in the overlapping portion of the sheet 24 and the cover 226, and the through holding portion may penetrate through the through hole.

In the holding structure 310 of the flat wiring member 320 according to the third modification shown in FIG. 5, the through hole 320h forms an intermediate portion in the width direction of the flat wiring member 320 between the plurality of electric wires 22 as in the first modification. It penetrates. Here, the through hole 320h is formed in the sheet 24.

Further, as in the second modification, the cover 326 is added.

The penetration holding portion 14 penetrates through the through hole 320h formed in the sheet 24 and is hooked on the sheet 24 in a retaining state around the through hole 320h.

The cover 326 makes it easy for the flat wiring member 320 to be kept in a constant flat shape. Therefore, the flat wiring member 320 is easily maintained in a state along the main surface of the plate-shaped portion 12 by the holding portion such as the penetration holding portion 14. As a result, floating, fluttering, etc. of the flat wiring member 320 are suppressed.

Further, in this modification, the penetration holding portion 14 penetrates a part of the intermediate portion in the width direction of the flat wiring member 320 between the plurality of electric wires 22. Therefore, both side portions of the flat wiring member 320 are held in a well-balanced manner, and floating, fluttering, etc. of both side portions of the flat wiring member 320 are suppressed.

In the third modification, a through hole may be formed in the cover 326, and the through holding portion 14 may penetrate the through hole and be hooked on the cover 326 in a retaining state. As a result, the flat wiring member 320 is more firmly held on the main surface of the plate-shaped portion 12.

In the holding structure 410 of the flat wiring member 20 according to the fourth modification shown in FIG. 6, the penetrating holding portion 414 is formed with the penetrating portion 415 and the retaining portion 416 separately. Then, when holding the flat wiring member 20, the retaining portion 416 is attached to the retaining portion 416. That is, the retaining portion 416 is fixed at a fixed position in the extending direction of the penetrating portion 415. As a result, the retaining portion 416 can hold the flat wiring member 20.

More specifically, the penetrating portion 415 is, for example, a rod-shaped member having a thread groove formed therein. Such a penetrating portion 415 is sometimes called a stud bolt or the like. The retaining portion 416 is, for example, a nut that can be screwed into the penetrating portion 415. The retaining portion 416 may have a structure in which it is hooked on the penetrating portion 415 by a latch structure or the like.

Then, in a state where the penetrating portion 415 is penetrated through the through hole 20h of the flat wiring member 20, the retaining portion 416 is fitted from the tip end portion of the penetrating portion 415 and fixed at a predetermined position. As a result, the retaining portion 416 is caught by the flat wiring member 20 around the through hole 20h.

In FIG. 6, another component 450 using the penetration portion 415 is fixed. The other component 450 is a protector, an electronic device, or the like that protects other electric wires mounted on the vehicle. A mounting piece 452 is formed on the other component 450. A through hole through which the through portion 415 can penetrate is formed in the mounting piece 452.

The penetration portion 415 penetrates the through hole formed in the mounting piece 452. The retaining portion 416 is attached to the penetrating portion 415 from the tip of the penetrating portion 415. As a result, the retaining portion 416 is hooked on the flat wiring member 20 via the mounting piece 452. Therefore, the penetration holding portion 414 can hold not only the flat wiring member 20 but also other parts 450 at a fixed position.

The penetration holding portion in this case may also have the same configuration as the penetration holding portion 14 in which the penetration portion 15 and the retaining portion 16 are integrally formed, as described in the first embodiment.

In this modification, the penetration holding portion 14 holds the flat wiring member 20 and the component 450 in the vehicle, which contributes to simplification of the vehicle configuration.

[Embodiment 2]
The positioning structure of the flat wiring member according to the second embodiment will be described. Here, an example in which the positioning structure of the flat wiring member is a holding structure will be described. FIG. 7 is a cross-sectional view showing a holding structure 510 of the flat wiring member 520. In the description of the present embodiment, the same reference numerals are given to the components as described in the first embodiment, and the description thereof is omitted.

The holding structure 510 includes a holding portion 514 and a flat wiring member 520.

The flat wiring member 520 may have the same configuration as the flat wiring member 20 except that it is not necessary to form the through hole 20h.

The holding portion 514 protrudes from the plate-shaped portion 12. The holding portion 514 holds the flat wiring member 520 in a state where the flat wiring member 520 is placed along the main surface of the plate-shaped portion 12.

More specifically, the holding portion 514 is a member formed of metal, resin, or the like. The plate-shaped portion 12 and the holding portion 514 may be integrally formed members. The plate-shaped portion 12 and the holding portion 514 may be formed separately, and the holding portion 514 may be fixed to the plate-shaped portion 12. Fixation of the holding portion 514 to the plate-shaped portion 12 can be realized by various configurations including a well-known configuration as illustrated in the first embodiment.

In the present embodiment, the holding portion that protrudes from the plate-shaped portion 12 and holds the flat wiring member 520 includes a configuration in which the flat wiring member 520 is held from the side of the flat wiring member 520, that is, the side holding portion. An example including 514 will be described.

The side holding portion 514 includes a base portion 515 and a sandwiching portion 516. The base portion 515 projects from the main surface of the plate-shaped portion 12. Here, the base portion 515 is formed in a plate shape that projects perpendicularly to the plate-shaped portion 12. The sandwiching portion 516 protrudes from the base portion 515. The surface of the sandwiching portion 516 facing the plate-shaped portion 12 side extends in a direction different from that of the main surface of the plate-shaped portion 12. Here, the sandwiching portion 516 is formed in a plate shape orthogonal to the base portion 515 and extending at intervals with respect to the main surface of the plate-shaped portion 12. Further, the sandwiching portion 516 is formed to have a protruding dimension equal to or larger than the width of the flat wiring member 520.

The flat wiring member 520 is sandwiched between the plate-shaped portion 12 and the sandwiching portion 516 in a state where the flat wiring member 520 is arranged along the main surface of the plate-shaped portion 12. Preferably, the distance between the plate-shaped portion 12 and the sandwiching portion 516 is set to be smaller than the maximum thickness dimension of the flat wiring member 520, and the sandwiching portion 516 is elastically deformed. Then, the flat wiring member 520 is sandwiched by the force that the sandwiching portion 516 presses the flat wiring member 520 against the plate-shaped portion 12 side. Even if the distance between the plate-shaped portion 12 and the sandwiching portion 516 is larger than the maximum thickness dimension of the flat wiring member 520, the flat wiring member 520 is surrounded by the plate-shaped portion 12, the base portion 515, and the sandwiching portion 516. It is held in the space.

The side holding portion 514 may be provided to some extent along the extending direction of the side portion of the flat wiring member 520, or may be partially provided. The protruding dimension of the sandwiching portion 516 may be smaller than the width dimension of the flat wiring member 520. Even in this case, it is preferable that the sandwiching portion 516 presses the flat wiring member 520 toward the plate-shaped portion 12 in an elastically deformed state.

Also in the second embodiment, the flat wiring member 520 is easily held with respect to the plate-shaped portion 12.

In particular, since the flat wiring member 520 may be arranged between the plate-shaped portion 12 and the sandwiching portion 516, the flat wiring member 520 is easily held against the plate-shaped portion 12. Further, since the flat wiring member 520 does not have to have a through hole formed, the width of the flat wiring member may be small.

An example of modification based on the second embodiment will be described. In the holding structure 610 of the flat wiring member 620 according to the fifth modification shown in FIG. 8, side holding portions 614 are provided on both sides of the flat wiring member 620.

The side holding portion 614 includes a base portion 615 and a sandwiching portion 616, similarly to the side holding portion 514. The sandwiching portion 616 is set to a length sufficient to sandwich both outer portions of the electric wire 22 in the flat wiring member 620.

According to this example, both side portions of the flat wiring member 620 are held by a pair of side holding portions 614. Since the flat wiring member 620 does not have to have a through hole formed, the flat wiring member 620 is easily held by the plate-shaped portion 12.

Further, the flat wiring member 620 has a configuration in which a cover 626 is added to the flat wiring member 520. Therefore, the flat wiring member 620 is less likely to be deformed, and the flat wiring member 620 is less likely to escape from the pair of side holding portions 614. The cover 626 also contributes to reducing the number of holding points by the pair of side holding portions 614.

Further, the side holding portion 614 covers the cover 626. Therefore, the side holding portion 614 holds the side portion of the cover 626. From this point as well, the flat wiring member 620 is likely to be kept in a state along the plate-shaped portion 12.

The cover 626 may be located on the opposite side of the plate-shaped portion 12. As a result, the electric wire 22 is protected by the cover 626 between the pair of side holding portions 614.

In the holding structure 710 of the flat wiring member 720 according to the sixth modification shown in FIG. 9, a side holding portion 714 is provided on one side of the flat wiring member 720, and a penetration holding portion 814 is provided on the other side.

The side holding portion 714 has the same configuration as the side holding portion 614. The penetration holding portion 814 has the same configuration as the penetration holding portion 14 described in the second embodiment.

The flat wiring member 720 has the same configuration as the flat wiring member 220 described in the second modification shown in FIG.

One side portion of the flat wiring member 720 is held by the side holding portion 714. A cover 226 extends from the other side of the flat wiring member 720, and a through hole 220h is formed in the cover 226. The penetration holding portion 814 penetrates the through hole 220h and holds the other side portion of the flat wiring member 720.

In the holding structure 710, for example, after one side portion of the flat wiring member 720 is fitted in the side holding portion 714 (see the flat wiring member 720 indicated by the alternate long and short dash line in FIG. 9), the flat wiring member 720 and other parts thereof. The side portion is pushed toward the penetration holding portion 814. Then, the penetration holding portion 814 penetrates through the through hole 220h. As a result, both side portions of the flat wiring member 720 are held by the side holding portion 714 and the through holding portion 814.

According to this example, the through holes 220h formed in the flat wiring member 720 are reduced as much as possible. Therefore, both side portions of the flat wiring member 720 are firmly held with a relatively simple configuration.

Further, since the flat wiring member 720 includes the cover 226, the flat wiring member 720 is easily held firmly along the plate-shaped portion 12.

[Embodiment 3]
The positioning structure of the flat wiring member according to the third embodiment will be described. FIG. 10 is a schematic plan view showing a positioning structure 910 of the flat wiring member 920 according to the third embodiment. FIG. 11 is a sectional view taken along line XI-XI of FIG.

The positioning structure 910 of the flat wiring member 920 includes a positioning portion 914 and a flat wiring member 920. The flat wiring member 920 is a flat wiring member 920 including a plurality of linear transmission members (here, electric wires 22), as in the first embodiment. The positioning unit 914 positions the flat wiring member 920 in at least one direction along the mounting target surface 912a in a state where the flat wiring member 920 is aligned with the mounting target surface 912a of the mounting target portion 912 in the vehicle. In the third embodiment, unlike the first and second embodiments, the positioning portion 914 does not have to hold the flat wiring member 920 so as not to be far from the mounting target portion 912. The positioning unit 914 is based on the premise that the flat wiring member 920 is fixed to the mounting target portion 912 by a fixing member different from the positioning unit 914. For example, the flat wiring member 920 is fixed to the mounting target portion 912 with double-sided tape or the like. When the flat wiring member 920 is attached to the attachment target portion 912 by another fixing member such as double-sided tape, the positioning portion 914 serves to position the flat wiring member 920 so that the attachment work is facilitated.

More specifically, it is assumed that the mounting target portion 912 is a part of a metal body in a vehicle, a part of an interior panel, various parts mounted on the vehicle, and the like. A mounting target surface 912a is formed around the mounting target portion 912. The mounting target surface 912a may be a flat surface, a curved surface, or a curved surface mixed with irregularities. The mounting target portion 912 may be a set of a plurality of portions. Therefore, the mounting target surface 912a may be set with respect to the surfaces of a plurality of portions.

The flat wiring member 920 includes a plurality of electric wires 22 and a sheet 924 as in the first embodiment. Further, the flat wiring member 920 includes a cover 926 that covers a plurality of electric wires 22. The cover 926 covers the electric wire 22 from the side opposite to the seat 924. Both sides of the cover 926 are fixed to both sides of the seat 924. Cover 926 may be omitted. The configuration of the flat wiring member 920 is the same as that described in the first or second embodiment.

A positioning hole 921h is formed in the flat wiring member 920. The positioning hole 921h is a hole that penetrates both sides of the flat wiring member 920. Here, a projecting piece 921 protruding outward from one side of the flat wiring member 920 is formed. Here, the projecting piece 921 is formed in a square shape. The projecting piece 921 may have other shapes, for example, a semicircular shape, a triangular shape, or the like. The projecting piece 921 is, for example, a portion formed so that one side portion of the cover 926 extends outward. The projecting piece 921 may be formed by the sheet 924, or may be formed by overlapping the sheet 924 and the cover 926. A positioning hole 921h is formed in the projecting piece 921. Here, the positioning hole 921h is formed in a square shape. The positioning hole 921h may have a circular shape, an arbitrary polygonal shape, or the like.

Here, a plurality of projecting pieces 921 (here, two) are formed at intervals with respect to one side of the flat wiring member 920. Since a plurality of (two here) positioning holes 921h are formed, the flat wiring member 920 is positioned at a plurality of positions (two here). As a result, the flat wiring member 920 is positioned in a predetermined posture.

The positioning portion 914 projects from the mounting target portion 912 as an example. The positioning portion 914 does not need to protrude from the mounting target portion 912. The positioning portion 914 may protrude from a component in the vicinity of the mounting target portion 912. In this case, the positioning portion 914 may be provided at a position where the flat wiring member 920 fixed to the mounting target portion 912 can be positioned at a predetermined fixed position on the mounting target portion 912 during the fixing operation. A portion extending outward may not be formed on the side of the flat wiring member 920, and a positioning hole may be formed on the inside of the edge of the flat wiring member. The positioning portion 914 may be a protrusion formed exclusively for positioning, or may be a protrusion-shaped portion for other purposes.

The positioning portion 914 may penetrate the positioning hole 921h with the flat wiring member 920 along the mounting target surface 912a. The positioning portion 914 may have a rod shape such as a round bar, a square bar, or a bolt, or may have a plate shape. The positioning portion 914 does not need to have a shape to prevent the positioning portion 914 from coming off while penetrating the positioning hole 921h. Therefore, the positioning portion 914 does not need to have a shape having the retaining piece 16a as in the first embodiment. The positioning portion 914 may have a shape of being hooked around the positioning hole 921h. For example, a part of the peripheral surface of the tip end portion of the positioning portion 914 may have a shape protruding outward. Here, an example is shown in which the positioning portion 914 has a plate shape and the tip portion thereof is bent toward one side. When the tip of the positioning portion 914 is bent to the side opposite to the arrangement position of the flat wiring member 920, the tip of the positioning portion 914 is inside the positioning hole 921h with the positioning portion 914 inserted into the positioning hole 921h. It gets caught in the peripheral part. Therefore, it is difficult for the positioning portion 914 to come out of the positioning hole 921h. The material of the positioning portion 914 is not particularly limited, and may be formed of metal or resin.

Then, the positioning portion 914 is set to penetrate the positioning hole 921h in a state where the flat wiring member 920 is arranged at a predetermined arrangement position on the mounting target surface 912a. In a state where the positioning portion 914 penetrates the positioning hole 921h, the flat wiring member 920 is positioned at a fixed position with respect to the mounting target surface 912a. In this state, the positioning portion 914 only penetrates the positioning hole 921h on one side of the flat wiring member 920. Therefore, in a state where the positioning portion 914 penetrates the positioning hole 921h, the flat wiring member 920 is separated from the mounting target surface 912a, and the flat wiring member 920 is finally fixed to the mounting target surface 912a. Is easily carried out. For example, the work of fixing the mounting target surface 912a and the flat wiring member 920 with the adhesive member is easily performed. This work includes, for example, the work of peeling the release paper of the double-sided tape attached in advance to the flat wiring member 920, or the work of arranging the adhesive member on the flat wiring member 920 or the mounting target surface 912a, and further. The work of pressing the flat wiring member 920 against the mounting target surface 912a while finely adjusting the mounting position of the flat wiring member 920 with respect to the mounting target surface 912a may be included.

According to the present embodiment, the flat wiring member 920 can be positioned in at least one direction along the mounting target surface 912a with the flat wiring member 920 along the mounting target surface 912a. Since the positioning portion 914 is penetrated through the positioning hole 921h, the positioning state can be maintained more reliably and easily. In this state, for example, the main fixing work of the flat wiring member 920 is easily performed. Further, in this state, for example, the connector connection at each end is performed, so that the connector connection work can be easily performed. Further, when assembling the flat wiring member 920, various operations may be performed with reference to the positioning of the positioning hole 921h with respect to the positioning portion 914, so that the assembling work is less likely to be confused.

At this time, since the positioning hole 921h is square, the posture of the flat wiring member 920 can be easily recognized. The posture of the flat wiring member 920 can be easily recognized even when the projecting piece 921 is rectangular.

Further, since the positioning hole 921h exists only on one side of the flat wiring member 920, various operations for separating the flat wiring member 920 from the mounting target surface 912a can be easily performed in the positioning state. Further, since the positioning portion 914 is not penetrated through the positioning hole 921h in a retaining state, various operations for separating the flat wiring member 920 from the mounting target surface 912a can be easily performed from this point as well.

Further, since the positioning holes 921h are present at a plurality of locations, the flat wiring member 920 is positioned in a stable posture.

As shown in FIG. 12, the flat wiring member 920 may be changeable from a folded form in which at least a part is folded to an unfolded form in which the folding of the folded form is expanded. In the folded form, at least a part of the flat wiring member 920 is folded. In the unfolded form, the folded portion in the folded form is unfolded. The flat wiring member 20 in the unfolded form is wider than the flat wiring member 920 in the folded form. Conversely, the flat wiring member 920 in the folded form is smaller than the flat wiring member 20 in the deployed form. Therefore, the folded form is suitable for storage, transportation, placement work on the mounting surface 912a, and the like.

Here, the trunk line portion of the flat wiring member 920 is bent at a plurality of locations (here, two locations). The two bending points L1 and L2 are located at positions separated from each other in the longitudinal direction of the trunk line portion. One bending point L1 is located near one end of the trunk line portion, and the other bending point L2 is located near the other end of the trunk line portion. Therefore, in the folded form, both end portions of the trunk line portion of the flat wiring member 920 are folded toward the center side. In the flat wiring member 920, the portion between the bent portions L1 and L2 is the base portion 920B. As a result, the flat wiring member 920 in the folded form becomes relatively small. The bent portion can be grasped as a portion having low rigidity in, for example, the flat wiring member 920. For example, the bent portion may be a portion of the flat wiring member 920 having a small thickness. Further, the bent portion may be grasped as a portion where the flat wiring member 20 has a crease. Further, the bent portion may be grasped as a portion of the flat wiring member 20 where the cover 925 is not partially provided.

A positioning hole 921h is formed in the base portion 920B. Here, the projecting piece 921 is formed so as to project outward on one side in the base portion 920B. A positioning hole 921h is formed in the projecting piece 921.

In this example, the flat wiring member 920 may be arranged on the mounting target portion 912 in the folded form. Then, by penetrating the positioning portion 914 through the positioning hole 921h, another portion can be deployed while the base portion 920B is positioned. When the other parts are expanded, each connector 48 is connected to the connector of the device to which the connection is made.

Here, a manufacturing error, an assembly error, and the like may occur in the flat wiring member 920 and the connection destination component thereof. If the other connectors are developed with one connector as a reference, an error may be accumulated in the terminal portion to be connected last. Therefore, in the terminal portion, the error becomes large, and the size may be insufficient or a large slack may occur. In this example, other parts are developed with the base part 920B as a reference. Therefore, at the time of deployment, it is difficult for the error to be concentrated in one place, and it is easy to disperse it in each terminal portion. Therefore, the flat wiring member 920 is easily arranged because the size of each terminal portion is insufficient or a large slack is unlikely to occur.

Further, the positioning hole 921h is provided at an observable position in the folded form. Here, the projecting piece 921 projects laterally from the trunk line portion, and in the folded form, the other portion does not overlap the positioning hole 921h. Therefore, in the folded form, the projecting piece 921 and the positioning hole 921h can be observed from above. Therefore, when the flat wiring member 920 is arranged on the mounting target surface 912a in the folded form, the positioning portion 914 can be easily moved to the positioning hole 921h while the positional relationship between the positioning portion 914 and the positioning hole 921h is confirmed. It is penetrated. Then, the flat wiring member is deployed in a state where the flat wiring member 920 is positioned.

It should be noted that the configurations described in the above embodiments and the modifications can be appropriately combined as long as they do not conflict with each other. For example, the penetration holding portion and the side holding portion may coexist in the longitudinal direction of the flat wiring member.
