[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The holding member for flat wiring members of the present disclosure is as follows.

[0012] (1) A holding member for a flat wiring member that holds a flat wiring member, the holding member comprising: a base body; a holding base including a penetrating engagement portion protruding from the base body; and a pressing portion that sandwiches the flat wiring member between the base body and the pressing portion, the pressing portion including a mating engagement portion with which the penetrating engagement portion can be engaged, and the penetrating engagement portion is engaged with the mating engagement portion when it penetrates the flat wiring member, thereby sandwiching the flat wiring member between the base body and the pressing portion.

[0013] According to this holding member for a flat wiring member, the penetrating locking portion penetrates the flat wiring member and locks into the mating locking portion, sandwiching the flat wiring member between the base body and the pressing portion, so that the flat wiring member can be easily held even if the shape of the flat wiring member is changed.

[0014] (2) The flat wiring member holder of (1) may further include a hinge that connects the base body and the pressing portion so that the base body and the pressing portion can be opened and closed.

[0015] This allows the base body and the pressing portion to be easily handled as a single unit.

[0016] (3) In a holding member for a flat wiring member according to (1) or (2), the mating engaging portion may have an opening on the base body side that receives the penetrating engaging portion, and a recess next to the opening that accommodates a punched tongue piece extending from the periphery of the penetrating hole of the flat wiring member.

[0017] In this case, if a punched tongue is left on the periphery of the through hole when forming the through hole in the flat wiring member, the punched tongue can be let out into the recess, thereby ensuring that the through-hole locking portion is securely locked by the mating locking portion.

[0018] (4) A holding member for a flat wiring member according to (1) to (3), wherein the through-hole engaging portion includes a pillar portion protruding from the base body and an engaging protrusion portion protruding from the pillar portion, and the engaging protrusion portion may protrude on the opposite side of the periphery of the through hole of the flat wiring member from the portion where the punched tongue piece is connected.

[0019] In this case, the locking protrusion can be locked to the mating locking portion on the opposite side to the punched tongue, so the punched tongue is less likely to get caught in the locking portion between the locking protrusion and the mating locking portion, thereby ensuring that the through locking portion is securely locked by the mating locking portion.

[0020] (5) A holding member for a flat wiring member according to any one of (1) to (4), wherein the through-locking portion is located near one longitudinal end of the base body, an additional through-locking portion protrudes from the other longitudinal end of the base body, and further comprises an additional pressing portion that sandwiches the flat wiring member between itself and a portion of the base body near the other longitudinal end, wherein the additional pressing portion includes a mating additional pressing portion with which the additional through-locking portion can be engaged, and when the additional through-locking portion penetrates the flat wiring member, it may be engaged with the mating additional pressing portion, thereby sandwiching the flat wiring member between the portion of the base body near the other longitudinal end and the pressing portion.

[0021] This allows the flat wiring members to be held on both sides of the base body.

[0022] (6) In the holding member for flat wiring members according to any one of (1) to (5), a fixing portion to be fixed to a fixing object may protrude from the base body.

[0023] In this case, by fixing the fixing portion to the fixing object, the flat wiring member is held in a fixed position relative to the fixing object.

[0024] The wiring module of the present disclosure is as follows.

[0025] (7) A wiring module comprising a holding member for a flat wiring member described in any one of (1) to (6) and a flat wiring member, wherein a through hole is formed in the flat wiring member, and the flat wiring member is sandwiched between the base body and the pressing portion with the through-hole engaging portion passing through the through-hole.

[0026] According to this wiring module, the flat wiring member can be held by sandwiching the flat wiring member between the base body and the pressing portion at least in part around the portion of the flat wiring member where the through hole is formed, so that the flat wiring member can be held regardless of the width, shape, etc. of the flat wiring member.

[0027] (8) In the wiring module of (7), the flat wiring member may include a base member and a plurality of linear transmission members directly fixed to the base member at contact portions thereof.

[0028] This makes it possible to easily hold the flat wiring member including the base member and the plurality of linear transmission members fixed to the base member.

[0029] (9) In the wiring module of (8), the through hole may be formed in an area of ​​the base member outside the plurality of linear transmission members, and the base member and the pressing portion may sandwich the area of ​​the base member outside the plurality of linear transmission members.

[0030] This allows the flat wiring member to be held by utilizing the area of ​​the base member outside the linear transmission member.

[0031] [Details of the embodiments of the present disclosure] Specific examples of the holding member for a flat wiring member and the wiring module of the present disclosure are described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0032] [Embodiment 1] The flat wiring member holding member and the wiring module according to the first embodiment will be described below.

[0033] <Wiring module> Fig. 1 is a perspective view showing a wiring module 20. In Fig. 1, a flat wiring member 30 is indicated by a two-dot chain line. Figs. 2 and 3 are perspective views showing a flat wiring member holding member 40. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 1.

[0034] The wiring module 20 includes a flat wiring member holding member 40 and a flat wiring member 30.

[0035] The flat wiring member 30 is a flat wiring member including a circuit for wiring. The flat wiring member holding member 40 is a component that holds the flat wiring member 30. When the flat wiring member holding member 40 is fixed to the fixed object 10 while holding the flat wiring member 30, the holding portion of the flat wiring member 30 is supported at a predetermined position relative to the fixed object 10.

[0036] <Flat wiring materials> An example of a flat wiring member 30 will now be described. The flat wiring member 30 is a member that is mounted on a vehicle and serves as a power supply path for various devices in the vehicle, a ground path, and a signal transmission path. The flat wiring member 30 is formed so that its dimension in the thickness direction is smaller than its dimension in the width direction perpendicular to the thickness direction. The flat wiring member 30 includes a base member 32 and a plurality of linear transmission members 36. The plurality of linear transmission members 36 are supported along the base member 32, thereby supporting the plurality of linear transmission members 36 so as to be aligned flat.

[0037] The linear transmission member 36 may be any linear member that transmits electricity, light, etc. For example, the linear transmission member 36 may be a general electric wire having a core wire and a coating surrounding the core wire, or may be a bare conductor, a shielded wire, an enameled wire, a nichrome wire, an optical fiber, etc.

[0038] The linear transmission member 36 that transmits electricity may be any of various signal lines and power lines. The linear transmission member 36 that transmits electricity may be used as an antenna, a coil, or the like that sends or receives signals or power to or from space.

[0039] The linear transmission member 36 includes a transmission line body 36a that transmits electricity, light, or the like, and a coating 36b that covers the transmission line body. When the linear transmission member 36 is a general electric wire, the transmission line body is a core wire and the coating is an insulating coating. Multiple linear transmission members 36 may have the same thickness and the same structure. Multiple linear transmission members 36 may also have different thicknesses or different structures.

[0040] The linear transmission member 36 may be a single linear object, or may be a composite of multiple linear objects (such as a twisted wire or a cable in which multiple linear objects are assembled and covered with a sheath). Appropriate terminals, connectors, etc. are provided at the end of the linear transmission member 36 depending on the connection form between the linear transmission member 36 and the counterpart component.

[0041] The base member 32 holds a plurality of linear transmission members 36 in a lined-up state. Here, the base member 32 is a sheet formed separately from the linear transmission members 36. The linear transmission members 36 are arranged along a predetermined path on the main surface of the base member 32 formed in a sheet shape.

[0042] The plurality of linear transmission members 36 may be fixed to only one main surface of the base member 32, or may be fixed to both main surfaces.

[0043] The base member 32 is formed in a shape corresponding to the wiring path of the linear transmission members 36. For example, the base member 32 may be formed in a long, narrow rectangular shape. The base member 32 may be formed in a shape that curves in the width direction midway. A plurality of linear transmission members 36 may be fixed to the base member 32 along branching paths, in which case the base member 32 may be formed in a branching shape corresponding to the branching paths.

[0044] The material constituting the base member 32 is not particularly limited, but the base member 32 is formed from a material containing resin, such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PP (polypropylene). The base member 32 may be a fibrous material containing fibers, such as a nonwoven fabric, woven fabric, or knitted fabric, or may be a non-fibrous material. The non-fibrous material may be a solid member with a uniformly filled interior, or a foam formed by foam molding of resin. The base member 32 may also contain a material such as metal.

[0045] The base member 32 may be a single layer, or may have multiple layers laminated therein. When multiple layers are laminated, for example, a resin layer may be laminated on another resin layer. Another example is a resin layer and a metal layer. The base member 32 may also be a non-fiber material layer laminated on another non-fiber material layer, a non-fiber material layer laminated on a fiber material layer, or a fiber material layer laminated on another fiber material layer.

[0046] The base member 32 may be a bendable member, or may be a member having a rigidity sufficient to hold the plurality of linear transmission members 36 in a state where they are positioned in a plane while being curved, or may be a member having a rigidity sufficient to hold the plurality of linear transmission members 36 in a state where they are positioned two-dimensionally while being kept flat. The base member 32 may have a three-dimensional shape, such as having a wall partially erected thereon.

[0047] The linear transmission member 36 is fixed to the base member 32. The fixing method may be contact-site fixing, non-contact-site fixing, or a combination of both. Contact-site fixing refers to fixing the linear transmission member 36 and the base member 32 by adhering their contacting portions. Non-contact-site fixing refers to fixing other than contact-site fixing. For example, sewing thread, another base material, adhesive tape, or the like may be used to press the linear transmission member 36 toward the base member 32, or sewing thread, another base material, adhesive tape, or the like may be used to surround the linear transmission member 36 and the base member 32, sandwiching the linear transmission member 36 and the base member 32, thereby maintaining the linear transmission member 36 and the base member 32 in a fixed state. The following description will be given assuming that the linear transmission member 36 and the base member 32 are in a contact-site fixing state. The descriptions regarding contact-site fixing are also applicable to non-contact-site fixing unless inapplicable.

[0048] The contact area may be fixed by indirect fixation, direct fixation, or a combination of both in different areas. Here, indirect fixation refers to the linear transmission member 36 and the base member 32 being indirectly fixed to each other via an intermediary such as an adhesive, pressure-sensitive adhesive, double-sided adhesive tape, or hook-and-loop fastener. Direct fixation refers to the linear transmission member 36 and the base member 32 being directly fixed to each other without the use of a separate adhesive or the like. Direct fixation may involve, for example, melting a resin contained in at least one of the linear transmission member 36 and the base member 32 to fix them together. The following description will be given assuming that the linear transmission member 36 and the base member 32 are directly fixed to each other. All descriptions of direct fixation are also applicable to indirect fixation unless they are inapplicable.

[0049] When such a direct fixation state is formed, the resin may be melted by, for example, heat or a solvent. That is, the direct fixation state may be a state of direct fixation by heat or a state of direct fixation by a solvent. Preferably, the state of direct fixation by heat is used.

[0050] The means for achieving this direct fixation is not particularly limited, and various means can be used, including known means such as welding, fusion, and welding. For example, when forming a direct fixation by heat through welding, various welding means can be used, such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding. When a direct fixation is achieved by these means, the linear transmission member 36 and the base member 32 are directly fixed by that means. Specifically, for example, when a direct fixation is achieved by ultrasonic welding, the linear transmission member 36 and the base member 32 are directly fixed by ultrasonic welding. The portion where the direct fixation is achieved by heat through welding (the fixed portion between the linear transmission member 36 and the base member 32) is referred to as a welded portion, and the portion fixed by ultrasonic welding may be referred to as an ultrasonic welded portion, and the portion fixed by heat and pressure welding may be referred to as a heat and pressure welded portion, etc.

[0051] In the case of direct fixation, only the resin contained in the coating of the linear transmission member 36 may be melted, or only the resin contained in the base member 32 may be melted. In these cases, the melted resin may adhere to the outer surface of the other, forming a relatively clear interface. Also, in the case of direct fixation, both the resin contained in the coating of the linear transmission member 36 and the resin contained in the base member 32 may be melted. In this case, the two resins may mix together and not form a clear interface. In particular, when the coating of the linear transmission member 36 and the base member 32 contain resins that are easily miscible with each other, such as the same resin material, the two resins may mix together and not form a clear interface.

[0052] In this embodiment, the linear transmission member 36 is fixed to the base member 32 at the contact portion and directly fixed thereto via the fused portion 36d, that is, the contact portion is directly fixed thereto.

[0053] The flat wiring member 30 may include a cover 34. The cover 34 is fixed to the base member 32 so as to cover the linear transmission member 36.

[0054] The cover 34 is, for example, a sheet molded separately from the linear transmission member 36. The material constituting the cover 34 is not particularly limited, but like the base member 32, the cover 34 may be formed from a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PP (polypropylene). Also, like the base member 32, the cover 34 may be a fiber material having fibers such as a nonwoven fabric, woven fabric, or knitted fabric, or may be a non-fibrous material.

[0055] The cover 34 may have the same shape as the base member 32, may extend larger than the base member 32, or may be sized to fit within the base member 32. In this embodiment, the cover 34 is formed in the same shape as the base member 32, and is placed on the base member 32 with both side edges of the cover 34 aligned along both side edges of the base member 32.

[0056] The structure for fixing the cover 34 to the base member 32 is not particularly limited. For example, the cover 34 may be fused to the base member 32. The fusion may be performed by ultrasonic welding, heat and pressure welding, hot air welding, or high-frequency welding. The cover 34 may also be fixed to the base member 32 by adhesive, double-sided tape, sewing, or the like.

[0057] The cover 34 is fixed to the base member 32 in both outer regions of the region where the multiple linear transmission members 36 are lined up. In other words, both sides of the cover 34 are fixed to both sides of the base member 32. Between the fixing points on both sides, the multiple linear transmission members 36 are arranged side by side between the base member 32 and the cover 34. Note that the cover 34 is not directly fixed to the multiple linear transmission members 36.

[0058] A through hole 38 is formed in the flat wiring member 30. The through hole 38 is a hole formed for holding by a holding member 40 for a flat wiring member.

[0059] The through holes 38 are formed in the outer regions of the plurality of linear transmission members 36 of the base member 32. In this embodiment, the covers 34 are overlapping and joined to both outer regions of the base member 32. Therefore, the through holes 38 are formed to penetrate the base member 32 and the covers 34. The through holes 38 are formed, for example, in the shape of a rectangular hole. The through holes 38 may also be formed in other shapes, for example, in the shape of a circular hole, an elliptical hole, or a polygonal hole.

[0060] The flat wiring member 30 may have an uncut tongue piece 39 extending from the periphery of the through hole 38. The uncut tongue piece 39 is a portion of the base member 32 and the cover 34 that extends into the region inside the through hole 38.

[0061] For example, the through-holes 38 are formed by partially punching out the base member 32 and the cover 34 with a punching blade or the like. If the punched portions were completely separated from the base member 32 and the cover 34, scrap would be generated from the punched portions, requiring time and effort for waste disposal. Therefore, when forming the through-holes 38, a portion around the through-holes 38 is cut out and the remaining portion is left uncut. As a result, the portion that extended into the through-holes 38 remains connected to the base member 32 or the cover 34 as part of the periphery of the through-hole 38. This portion is the uncut tongue 39. For example, the uncut tongue 39 is cut off from the base member 32 or the cover 34 at three sides of the rectangular through-hole 38 and remains connected to the base member 32 or the cover 34 at the other side. This other side is, for example, a side of the periphery of the through-hole 38 that is located near a side edge of the base member 32.

[0062] The through-hole 38 can be opened by bending the remaining tongue piece 39 at the base end. In addition, when the through-hole 38 is open, the remaining tongue piece 39 can remain connected to a part of the main edge of the through-hole 38. This eliminates the need for waste disposal due to punching.

[0063] In this embodiment, the cover 34 covers the base member 32, and therefore the remaining tongue piece 39 has a two-piece structure consisting of a portion corresponding to the base member 32 and a portion corresponding to the cover 34. If the cover 34 were omitted, the remaining tongue piece 39 would have a single-piece structure corresponding to the base member 32.

[0064] The flat wiring member 30 is not limited to the above configuration. The flat wiring member 30 may be a wiring member in which a plurality of linear conductors are insulated from one another by an insulating member and maintained in a flat state, such as an FPC (Flexible Printed Circuit) or an FFC (Flexible Flat Cable). That is, the flat wiring member may be a wiring member in which a plurality of linear conductors are insulated from one another and maintained in a flat form, and which is formed with an overall thickness smaller than its width.

[0065] <Retaining member for flat wiring components> The flat wiring member holding member 40 is a component that holds the flat wiring member 30. The flat wiring member 30 may be a component that is integrally molded from the same resin using a mold.

[0066] The flat wiring member holding member 40 includes a holding portion 42 including a holding base 44 and a pressing portion 50 .

[0067] The holding base 44 includes a base body 46 and a through-hole locking portion 48 .

[0068] The base body 46 is formed in a shape having a holding surface 46f, for example, a plate shape. The plate shape of the base body 46 may be any shape, for example, an elliptical, circular, or rectangular shape. In this embodiment, the base body 46 is formed in an elliptical plate shape. The holding surface 46f is formed as a flat surface.

[0069] The penetrating locking portion 48 protrudes from the holding surface 46f of the base body 46. The penetrating locking portion 48 protrudes in a direction perpendicular to the holding surface 46f. The position of the penetrating locking portion 48 is, for example, near one end of the holding surface 46f.

[0070] The pressing portion 50 is a portion that sandwiches the flat wiring member 30 between itself and the base main body 46. The pressing portion 50 has a mating locking portion 52 with which the through-hole locking portion 48 can be locked. With the flat wiring member 30 placed on the holding surface 46f, the through-hole locking portion 48 is inserted into the through-hole 38 of the flat wiring member 30. The through-hole locking portion 48 protrudes upward from the flat wiring member 30. The pressing portion 50 is placed on the holding surface 46f of the base main body 46 in a position facing the flat wiring member 30 with the flat wiring member 30 interposed therebetween. In this state, the through-hole locking portion 48 locks into the mating locking portion 52. Then, the flat wiring member 30 is sandwiched between the base main body 46 and the pressing portion 50.

[0071] The holding portion 42 may include a hinge 43 that connects the base main body 46 and the pressing portion 50 so that they can be opened and closed. The hinge 43 connects the portion of the base main body 46 opposite the penetrating locking portion 48 to the end of the pressing portion 50. The hinge 43 is a resin portion that is formed thinner than the base main body 46 and the pressing portion 50 so that it can be deformed.

[0072] The position of the holding portion 50 can be changed so as to be openable and closable relative to the base body 46, centering on the hinge 43. The position where the holding portion 50 faces the holding surface 46f of the base body 46 is the closed position. The position where the holding portion 50 is rotated around the hinge 43 so that the holding portion 50 is retracted from the position facing the holding surface 46f is the open position.

[0073] The pressing portion and the base body may be prepared as separate components and may be joined together by engaging the penetrating locking portion 48 with the mating locking portion 52. In this case, the holding portion may have multiple combinations of penetrating locking portions and mating locking portions.

[0074] In this embodiment, the flat wiring member holding member 40 further includes a fixing portion 60.

[0075] The fixing portion 60 protrudes from the base body 46. The fixing portion 60 is a portion that is fixed to a fixed object 10. The fixed object 10 is, for example, a part of a vehicle.

[0076] For example, the fixing portion 60 may have a structure including a pillar portion 62 and a locking piece 64 .

[0077] The pillar portion 62 is a long, thin portion that protrudes from a portion of the base body 46 opposite the holding surface 46f toward the opposite side of the holding surface 46f. In this embodiment, in order to mold the locking piece 64 using a mold, a long, thin opening 64h for mold removal is formed in the center of the base body 46. Both side portions of the base end of the pillar portion 62 are supported by the inner surface of the opening 64h at longitudinally intermediate positions of the opening 64h.

[0078] A pair of locking pieces 64 are supported on the pillar portion 62 so as to be able to elastically deform. The pair of locking pieces 64 are located on opposite sides of the pillar portion 62. In other words, the pillar portion 62 is located between the pair of locking pieces 64. The locking pieces 64 extend from the tip to the base end of the pillar portion 62, gradually moving away from the pillar portion 62. A locking recess 64g is formed on the outer portion of the tip of the locking piece 64.

[0079] A disc spring 47 is supported on the base body 46. The disc spring 47 extends outward from the base end of the pillar portion 62.

[0080] When the fixing portion 60 is inserted into the fixing hole 12 of the fixing object 10, the pair of locking pieces 64 come into contact with the periphery of the fixing hole 12 and elastically deform in a direction approaching the column portion 62. When the locking recesses 64g of the pair of locking pieces 64 pass through the fixing hole 12, the pair of locking pieces 64 elastically return to their original shape. Then, the locking recesses 64g of the pair of locking pieces 64 lock onto the periphery of the fixing hole 12 from the opposite side to the base body 46. In addition, the disc spring 47 elastically comes into contact with the fixing object 10 from the base body 46 side, at the periphery of the fixing hole 12. As a result, the fixing object 10 is sandwiched between the locking pieces 64 and the disc spring 47 around the periphery of the fixing hole 12, and the fixing portion 60 is fixed to the fixing object 10.

[0081] The fixing portion 60 may be formed on the pressing portion 50.

[0082] Furthermore, the structure of the fixing portion for fixing to the fixing object is not limited to the above example. For example, the fixing portion may have a so-called tree-shaped clip structure, or may have a structure that is fixed to a stud bolt fixed to the vehicle.

[0083] Furthermore, the portion for fixing to the vehicle does not have to be formed directly on the holding portion, but may be a portion formed on various components fixed to the vehicle, such as a protector for protecting electric wires.

[0084] <Sandwich structure> The structure in which the holding portion 42 sandwiches and holds the flat wiring member 30 will be described in more detail.

[0085] As described above, the hinge 43 and the through-locking portion 48 are located at opposite ends of the base body 46 .

[0086] The through-locking portion 48 includes a pillar portion 48a that protrudes from the base body 46 and a locking projection 48b that protrudes from the pillar portion 48a.

[0087] The pillar portion 48a is formed, for example, in the shape of a rectangular plate. The pillar portion 48a extends perpendicular to the holding surface 46f. The width direction of the pillar portion 48a is aligned with the direction of the rotation axis of the pressing portion 50 formed by the hinge 43.

[0088] The locking protrusion 48b protrudes outward from one main surface of the tip of the pillar 48a. The locking protrusion 48b has an inclined surface that reduces the protruding dimension of the locking protrusion 48b toward the tip of the pillar 48a. The surface of the locking protrusion 48b facing the base end of the pillar 48a is formed in a plane perpendicular to the pillar 48a.

[0089] The locking protrusion 48b preferably protrudes from the peripheral edge of the through-hole 38 on the opposite side to the portion where the remaining tongue piece 39 is connected.

[0090] In this embodiment, the remaining tongue piece 39 is connected to the periphery of the through-hole 38 on the outer side in the width direction of the base member 32. Therefore, when the penetrating locking portion 48 passes through the through-hole 38, the remaining tongue piece 39 is located closer to the hinge 43 than the pillar portion 48a.

[0091] Therefore, the locking protrusion 48b is formed so as to protrude from the pillar portion 48a on the side opposite to the hinge 43. In other words, the locking protrusion 48b locks with the mating locking portion 52 of the pressing portion 50 on the side opposite to the hinge 43.

[0092] As described above, the remaining tongue piece 39 and the locking protrusion 48b are arranged on opposite sides of the pillar portion 48a. This makes it difficult for the remaining tongue piece 39 to get caught between the locking portion between the locking protrusion 48b and the mating locking portion 52, allowing the locking protrusion 48b to be more reliably locked to the mating locking portion 52.

[0093] The pressing portion 50 includes a pressing portion main body 54 and a mating locking portion 52 .

[0094] The pressing portion main body 54 is formed in a plate shape connected to the base main body 46 via the hinge 43. A bent portion 54V may be present between the portion of the pressing portion main body 54 connected to the hinge 43 and the opposite end thereof. The portion of the pressing portion main body 54 closer to the base end than the bent portion 54V may be formed as an inclined portion 54a, and the portion closer to the tip end than the bent portion 54V may be formed as a horizontally opposed portion 54b. When the through-locking portion 48 is locked with the mating locking portion 52, the inclined portion 54a may be inclined with respect to the holding surface 46f, and the horizontally opposed portion 54b may be closer to a horizontal position with respect to the holding surface 46f than the inclined portion 54a. This makes it easier to ensure a gap between the holding surface 46f and the horizontally opposed portion 54b that allows the flat wiring member 30 to be placed therein.

[0095] An opening 54h is formed in the widthwise middle of the pressing portion main body 54, and an elastic pressing piece 55 is formed so as to be positioned within the opening 54h in a plan view. The base end of the elastic pressing piece 55 is continuous with the edge of the opening 54h on the hinge 43 side. The elastic pressing piece 55 extends from the base end toward the holding surface 46f as it moves toward the through-hole locking portion 48. In other words, the base end of the elastic pressing piece 55 is contained within the opening 54h. The elastic pressing piece 55 protrudes from within the opening 54h toward the holding surface 46f as it moves toward the tip end. The elastic pressing piece 55 can be elastically deformed, with its base end as a support point, to change the amount of protrusion relative to the pressing portion main body 54.

[0096] With the flat wiring member 30 placed on the holding surface 46f, the pressing portion 50 is positioned opposite the holding base 44, and the through-hole locking portion 48 locks into the mating locking portion 52. At this time, the elastic pressing piece 55 elastically deforms in accordance with the thickness of the flat wiring member 30. Therefore, regardless of the thickness of the flat wiring member 30, the elastic pressing piece 55 can press the flat wiring member 30 toward the holding surface 46f between the through-hole locking portion 48 and the hinge 43.

[0097] The elastic pressing piece 55 may be omitted.

[0098] The mating locking portion 52 is connected to the pressing portion main body 54 on the opposite side to the hinge 43 .

[0099] The mating locking portion 52 has a locking hole 52h through which the through-locking portion 48 passes. In this embodiment, the mating locking portion 52 protrudes beyond the outward surface of the pressing portion main body 54. The locking hole 52h is formed so as to penetrate from the surface of the mating locking portion 52 on the holding surface 46f side to the opposite side. When the through-locking portion 48 passes through the locking hole 52h, the locking protrusion 48b locks onto the outward surface of the mating locking portion 52.

[0100] The locking hole 52h has an opening 52ha that opens to the base body 46 side and receives the penetrating locking portion 48.

[0101] The mating locking portion 52 has a recess 52g adjacent to the opening 52ha that accommodates the remaining tongue piece 39. The recess 52g is a portion of the locking hole 52h that is wider than the outer opening that the locking protrusion 48b engages with. In this embodiment, the remaining tongue piece 39 is located closer to the hinge 43 than the through-locking portion 48, and therefore the recess 52g is located adjacent to the hinge 43 side of the opening 52ha.

[0102] When the through-locking portion 48 is inserted into the locking hole 52h, the remaining tongue piece 39 is pushed aside by the through-locking portion 48. This allows the remaining tongue piece 39 to fit into the recess 52g. Therefore, the remaining tongue piece 39 is unlikely to get between the through-locking portion 48 and the locking hole 52h and interfere with the locking of the through-locking portion 48. Furthermore, the remaining tongue piece 39 is unlikely to get between the holding surface 46f and the pressing portion main body 54 and interfere with the approach of the pressing portion main body 54 to the holding surface 46f. This allows the through-locking portion 48 to be smoothly locked with the mating locking portion 52.

[0103] It is preferable that the remaining tongue piece 39 is formed to have an extension length that does not reach the locking protrusion 48b. For example, it is preferable that the remaining tongue piece 39 is formed to have a length that is shorter than the distance between the holding surface 46f and the locking protrusion 48b.

[0104] Furthermore, the mating locking portion 52 has a guide surface 53g adjacent to the opening 52ha on the opposite side from the hinge 43. The guide surface 53g is formed on a surface that extends outward from the opening 52ha toward the opposite side from the hinge 43.

[0105] When the pressing portion 50 is rotated around the hinge 43 to move from the open position to the closed position, the tip of the penetrating locking portion 48 comes into contact with the guide surface 53g. The tip of the penetrating locking portion 48 is then pressed toward the hinge 43 by the guide surface 53g. This allows the locking protrusion 48b to easily move toward the hinge 43, making it easier for the penetrating locking portion 48 to pass through the locking hole 52h.

[0106] <Example of manufacturing method> An example of a method for manufacturing the wiring module 20 will be described.

[0107] First, the flat wiring member 30 and the flat wiring member holding member 40 are prepared.

[0108] A through hole 38 is formed in the base member 32 of the flat wiring member 30. A remaining tongue piece 39 extends from a portion of the periphery of the through hole 38. The remaining tongue piece 39 is connected to the periphery of the through hole 38 at a portion close to one of the side edges of the base member 32, and is separated from the base member 32 at other portions. For example, the remaining tongue piece 39 is connected to the base member 32 at a portion close to the side edge of the base member 32, and extends toward the center of the base member 32 in the width direction.

[0109] The through holes 38 may be formed at any position and in any number in the flat wiring member 30. For example, the through holes 38 may be formed at any position depending on the desired position and number of the flat wiring member 30 to be held by the holding member 40.

[0110] The holding member 40 is in a state where the pressing portion 50 is open relative to the holding base 44.

[0111] A portion of the flat wiring member 30 that is to be held by the holding member 40 is placed on the holding surface 46f of the holding member 40. For example, a portion of the flat wiring member 30 that is outside the through-hole 38 is placed on the holding surface 46f. At this time, the penetrating locking portion 48 is passed through the through-hole 38. Then, the remaining tongue piece 39 is pressed by the penetrating locking portion 48 and bent up. Note that either the base member 32 or the cover 34 of the flat wiring member 30 may face the holding surface 46f.

[0112] Then, the pressing portion 50 is rotated around the hinge 43 and pressed onto the holding base 44. As a result, the tip of the through-locking portion 48 comes into contact with the guide surface 53g, and the through-locking portion 48 is bent toward the hinge 43. This makes it easier for the through-locking portion 48 to enter the locking hole 52h. Finally, the locking protrusion 48b comes out of the locking hole 52h and locks with the mating locking portion 52 from the side opposite the base member 32.

[0113] When the through-locking portion 48 is passed through the mating locking portion 52, the remaining tongue piece 39 enters the recess 52g, making it difficult for the remaining tongue piece 39 to enter the locking hole 52h together with the through-locking portion 48. If the remaining tongue piece 39 were to enter the locking hole 52h together with the through-locking portion 48, elastic deformation of the through-locking portion 48 within the locking hole 52h would be hindered. Therefore, by the remaining tongue piece 39 entering the recess 52g, the through-locking portion 48 can smoothly elastically deform within the locking hole 52h and smoothly lock with the mating locking portion 52.

[0114] Furthermore, if the remaining tongue piece 39 is positioned on the locking protrusion 48b side of the through-hole locking portion 48, there is a possibility that the remaining tongue piece 39 will be interposed between the through-hole locking portion 48 and the mating locking portion 52 on the locking protrusion 48b side. In this case, there is a possibility that the engagement allowance of the locking protrusion 48b with the mating locking portion 52 will be reduced. If the remaining tongue piece 39 is positioned on the opposite side of the locking protrusion 48b with respect to the through-hole locking portion 48, the remaining tongue piece 39 will be less likely to interfere with the engagement between the locking protrusion 48b and the mating locking portion 52.

[0115] Furthermore, as the pressing portion 50 approaches the holding base 44, the elastic pressing piece 55 comes into contact with the flat wiring member 30. As the pressing portion 50 approaches the holding base 44, the elastic pressing piece 55 elastically deforms so as to enter the opening 54h. In other words, as the pressing portion 50 approaches the holding base 44, the elastic pressing piece 55 is pressed toward the opening 54h by the flat wiring member 30, and the amount of protrusion of the elastic pressing piece 55 from the pressing portion main body 54 becomes smaller.

[0116] When the locking protrusion 48b is locked with the mating locking portion 52, a space corresponding to the thickness of the sandwiched portion of the flat wiring member 30 is provided between the tip of the elastic pressing piece 55 and the holding surface 46f. In this state, the elastic pressing piece 55 presses the flat wiring member 30 against the holding surface 46f.

[0117] The flat wiring member 30 is firmly held by being sandwiched between the holding surface 46f and the elastic pressing piece 55. Furthermore, the flat wiring member 30 is pressed against the holding surface 46f by the elastic pressing piece 55, so the flat wiring member 30 is held in a fixed position with the holding surface 46f as a reference.

[0118] <Effects, etc.> With the wiring module 20 and the flat wiring member holder 40 configured as described above, when the through-hole locking portion 48 penetrates the flat wiring member 30, the through-hole locking portion 48 locks with the mating locking portion 52, sandwiching the flat wiring member 30 between the base body 46 and the pressing portion 50. This allows the flat wiring member 30 to be held regardless of its width, shape, etc. Therefore, the flat wiring member holder 40 is not a dedicated component for holding flat wiring members 30 of a predetermined width, but can be used as a general-purpose component for holding flat wiring members 30 of various widths and shapes. Furthermore, the design of the holder 40 can be easily adapted to components of wiring support components and the like of various shapes as a configuration for holding various portions of the flat wiring member 30. Therefore, the flat wiring member 30 can be easily held even if the shape, such as the width, of the flat wiring member 30 is changed.

[0119] Furthermore, since the base body 46 and the holding portion 50 are connected by the hinge 43, the base body 46 and the holding portion 50 can be easily handled as a unit.

[0120] Furthermore, the mating locking portion 52 has a recess 52g adjacent to the opening 52ha that accommodates the remaining tongue piece 39 extending from the periphery of the through hole 38. Therefore, even if the remaining tongue piece 39 is left behind when forming the through hole 38 in the flat wiring member 30, the remaining tongue piece 39 can escape into the recess 52g. This makes it less likely that the remaining tongue piece 39 will interfere with the locking of the through locking portion 48 and the mating locking portion 52, and the through locking portion 48 and the mating locking portion 52 can be more reliably locked together.

[0121] Furthermore, the locking protrusion 48b of the through-hole locking portion 48 protrudes from the periphery of the through-hole 38 on the opposite side from the portion where the remaining tongue piece 39 continues. Therefore, the locking protrusion 48b can lock with the mating locking portion 52 on the opposite side from the remaining tongue piece 39. This makes it difficult for the remaining tongue piece 39 to get into the locking portion between the locking protrusion 48b and the mating locking portion 52. This allows the through-hole locking portion 48 to be securely locked by the mating locking portion 52.

[0122] Furthermore, a fixing portion 60 protrudes from the base body 46, and the fixing portion 60 is fixed to the fixing object 10. For example, by inserting the fixing portion 60 into the fixing hole 12 and fixing it, the flat wiring member 30 is held in a fixed position relative to the fixing object.

[0123] Furthermore, the holding member 40 can easily fix the flat wiring member 30 including, for example, the base member 32 and the plurality of linear transmission members 36 .

[0124] In this case, the base member 32 and the pressing portion 50 can hold the flat wiring member 30 by sandwiching and holding the outer regions of the plurality of linear transmission members 36 of the base member 32. Because it is not necessary to sandwich the linear transmission members 36, the holding portion can be made thin, and localized force does not need to be applied to the linear transmission members 36.

[0125] Alternatively, a part of the flat wiring member 30 may protrude outward, and the holding member 40 may hold the part protruding outward.

[0126] [Embodiment 2] A description will now be given of a flat wiring member holding member 140 and a wiring module 120 according to embodiment 2. Fig. 5 is a perspective view showing the flat wiring member holding member 140. Fig. 6 is a cross-sectional view showing the wiring module 120. In the description of this embodiment, components similar to those described so far are given the same reference numerals and descriptions thereof will be omitted.

[0127] The flat wiring member holding member 140 includes a holding base 144 , a pressing portion 50 , and an additional pressing portion 150 .

[0128] The holding base 144 is formed in an elongated shape and includes a base body 146, the through-locking portion 48, and an additional through-locking portion 148.

[0129] The base body 146 is formed in the shape of an elongated plate, one of whose main surfaces is a holding surface 146f. The through-locking portion 48 is located near one longitudinal end of the base body 146. The holding portion 50 is supported on one longitudinal end of the base body 146 via a hinge 43 so as to be openable and closable. Note that the holding portion 50 does not necessarily have to have the inclined portion 54a.

[0130] Therefore, similarly to the first embodiment, one side portion of the flat wiring member 30 is sandwiched and held between one end of the base body 146 and the pressing portion 50.

[0131] An additional through-locking portion 148 projects from the other longitudinal end of the holding base 144. The additional through-locking portion 148 has the same configuration as the through-locking portion 48.

[0132] The flat wiring member holding member 140 further includes an additional pressing portion 150 that sandwiches the flat wiring member 30 between itself and a portion of the base body 146 near the other longitudinal end. The additional pressing portion 150 includes a mating additional locking portion 152 with which the additional through-locking portion 148 can be locked. The additional pressing portion 150 has the same configuration as the pressing portion 50, and the mating additional locking portion 152 has the same configuration as the mating locking portion 52. The additional pressing portion 150 is supported on the other longitudinal end of the base body 146 via a hinge 143 so as to be openable and closable.

[0133] The additional holding portion 150 including the additional penetrating locking portion 148 and the opposing additional locking portion 152 may have a plane-symmetrical shape with respect to the holding portion 50 including the penetrating locking portion 48 and the opposing locking portion 52, with a plane that crosses the longitudinal center of the base body 146 as the plane of symmetry.

[0134] The fixing portion 60 protrudes from the longitudinal intermediate portion of the base main body 146 on the opposite side to the holding surface 146f. Therefore, the longitudinal intermediate portion of the holding base 144 can be supported on the fixed object 10 by the fixing portion 60.

[0135] A longitudinal intermediate portion of the flat wiring member 30 is placed on the holding surface 146f of the base body 146. At this time, the longitudinal direction of the flat wiring member 30 is oriented perpendicular to the longitudinal direction of the base body 146. A portion of the flat wiring member 30 located on one outer side relative to the plurality of linear transmission members 36 is disposed on one longitudinal end portion of the base body 146, and a portion of the flat wiring member 30 located on the other outer side relative to the plurality of linear transmission members 36 is disposed on the other longitudinal end portion of the base body 146. The plurality of linear transmission members 36 are disposed between the through-hole locking portion 48 and the additional through-hole locking portion 148.

[0136] When the penetrating locking portion 48 rotates from the open position to the closed position around the hinge 43, one widthwise side portion of the flat wiring member 30 is sandwiched between one longitudinal end of the base body 146 and the pressing portion 50, as described in embodiment 1. When the additional penetrating locking portion 148 rotates from the open position to the closed position around the hinge 143, the other widthwise side portion of the flat wiring member 30 is sandwiched between the other longitudinal end of the base body 146 and the additional pressing portion 150, as described above.

[0137] When attention is paid to the configuration of one longitudinal end side of the base body 146 and the configuration of the other longitudinal end side of the base body 146, the flat wiring member 30 can be held regardless of the width, shape, etc. of the flat wiring member 30. For example, a change in the width of the flat wiring member 30 can be accommodated by simply changing the design of the length of the base body 146, without changing the shapes of the pressing portion 50, the penetrating locking portion 48, the additional pressing portion 150, and the additional penetrating locking portion 148. Therefore, even if the shape of the flat wiring member 30, such as the width, is changed, the flat wiring member 30 can be easily held by changing the length of the base body 146.

[0138] Furthermore, the flat wiring member 30 can be firmly held at both ends of the base body 146 in the longitudinal direction.

[0139] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
