Wire harness layout structure

Abstract

This invention provides a wiring harness layout structure that reduces the overall height of the wiring harness in a way that allows the wiring harness to be assembled to the side of the vehicle body, and makes the assembly operation of the wiring harness to the side of the vehicle body easier. The wiring harness layout structure includes a wiring harness (W), a plate-shaped member (100) of the vehicle body, a main body (4) that engages with the plate-shaped member at its base end and extends along the plate-shaped member toward the front end, and an anti-detachment part (5) that prevents the wiring harness, which is accommodated in the gap (S) between the plate-shaped member and the main body, from detaching from the front end of the main body. The wiring harness accommodated in the gap is prevented from detaching at the front end of the main body by the anti-detachment part, which rotates with its accommodation. Moreover, through a series of rotations of the anti-detachment part up to the accommodation, the upper part (53) of the rotating body of the anti-detachment part, which was previously located at the highest position in the height direction (Z) from the main surface (100a) of the plate-shaped member, moves to a lower position, thus reducing the overall height of the layout structure (1).

Description

Technical Field

[0001] This invention relates to the wiring structure of wire harnesses. Background Technology

[0002] In vehicles, to secure wiring harnesses to the vehicle body, a clamping member is used that integrally comprises a holding part for holding the wiring harness and a locking part for assembly to the side of the vehicle body. The clamping member is bundled and held together with the wiring harness by a binding member such as adhesive tape, and in this bundled and held state, the locking part is inserted into a fixing hole on the side of the vehicle body for assembly to the side of the vehicle body.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2017-44243 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, a wiring harness is a bundle of multiple wires, including signal wires and power wires, bound together with tape or similar materials, and its cross-section is roughly circular. Such wiring harnesses are widely used in modern vehicles. In recent years, in order to ensure more interior space, there has been a desire to lay the wiring harness at a lower height from the main surface of the plate-like component when assembling it on the side of the vehicle body.

[0008] However, for example, if the wire harness is flattened from above to form a horizontally extended low-height state, and then assembled onto a plate-like member on the vehicle body side using a clamping member as in Patent Document 1, the low-height wire harness becomes a state where the outer periphery is surrounded by the clamping member and is uniformly pressed from the outer periphery towards the center of the inner periphery. As a result, the cross-section of the low-height wire harness approaches the original circular state, and the low-height state cannot be maintained. Furthermore, in the case of Patent Document 1, since the buckle securing the clamping member that surrounds the wire harness in a loop is located directly below the engaging portion of the assembly part that forms the plate-like member assembled towards the vehicle body side, the height of the clamping member itself increases, hindering the overall low-height design of the wire harness layout.

[0009] The problem to be solved by the present invention is to make the overall structure of the wiring harness lower in the form of assembling the wiring harness on the side of the vehicle body, and to make the assembly of the wiring harness easier.

[0010] means for solving problems

[0011] The wiring harness layout structure used to solve the above problems is characterized by,

[0012] The wiring harness layout structure includes:

[0013] The main body has its base end connected or snap-fitted to a plate-like portion disposed on the side of the vehicle body, and its front end extends along the main surface of the plate-like portion, capable of accommodating the wire harness from the front end towards the base end in a gap formed between the main body and the main surface; and

[0014] An anti-detachment part, located at the front end of the main body, prevents the wire harness contained within the gap from detaching from the gap.

[0015] The anti-detachment part integrally includes a rotating shaft portion connected to the main body portion and a rotating body connected to the rotating shaft portion.

[0016] The rotating body has:

[0017] The pressing plate extends from the rotating shaft into the gap;

[0018] The upper part of the rotating body extends from the rotating shaft in the opposite direction to the pressing piece, and is located above the rotating shaft in the height direction from the main surface of the plate-shaped part; and

[0019] The lower part of the rotating body is integrally connected to the upper part of the rotating body and is located lower than the rotating shaft.

[0020] The surface extending from the upper part of the rotating body to the lower part of the rotating body, opposite to the gap, is configured as a guide slope inclined in a manner opposite to the main surface of the plate-shaped part.

[0021] When a wire bundle with a thickness greater than the height of the gap is inserted into the gap, by pressing the wire bundle against the guide slope, a rotation is generated in the rotating body around the rotation axis, causing the pressing plate to face the main body side within the gap, the upper part of the rotating body to face the main surface side of the plate-like part, and the lower part of the rotating body to face the inside of the gap. As a result, the wire bundle enters between the lower part of the rotating body and the main surface of the plate-like part in a manner that is flattened and reduced in height by the guide slope. The lower part of the rotating body is then pushed upwards towards the pressing plate side, allowing it to enter the gap.

[0022] Upon entry, the wire harness enters between the pressing piece and the main surface of the plate-like portion, thereby preventing the rotation of the rotating body about the rotation axis from causing the pressing piece to face the main surface of the plate-like portion.

[0023] When the wire harness is contained within the gap, the lower part of the rotating body is released from the upward pushing state towards the pressing plate and returns to the position of blocking the inlet into the gap, forming an anti-detachment state for the contained wire harness. On the other hand, the pressing plate remains in a state where the wire harness has entered the lower side of the pressing plate, thus continuing the reverse rotation prevention state of the rotating body. Furthermore, through the rotation of the rotating body up to this point, the upper part of the rotating body remains at a position lower than the position at the beginning of the rotation.

[0024] According to the structure of the present invention described above, since the wire harness is not held at a certain height above the plate-shaped portion as in the conventional case, but is instead placed directly above the plate-shaped portion, the laying structure can be made lower in height. Furthermore, according to the structure of the present invention, the main body portion extending across the plate-shaped portion has a rotating body (anti-detachment part) provided at its front end side. By pressing the rotating body in a predetermined direction, it is rotated, thereby forming an entry point into the gap (wire harness receiving space) between the plate-shaped portion and the main body portion. Thus, the wire harness can be easily entered and accommodated in the gap simply by pressing the rotating body in a predetermined direction. Moreover, when the wire harness is accommodated in the gap, the rotating body (anti-detachment piece) automatically blocks the entry point to prevent detachment, and prevents the rotating body (pressing piece) from rotating in the opposite direction to itself, thus stabilizing and maintaining this anti-detachment state. Furthermore, when the rotating body is pressed in a specified direction by the wire harness, the pressing acts on the guide ramp, thereby flattening the wire harness downwards and making it easier to reduce its height, allowing it to be accommodated in a gap at this reduced height. In other words, since the reduction of the wire harness and assembly are carried out simultaneously by utilizing the guide ramp, the assembly operation becomes very easy.

[0025] The pressing plate can maintain the position of pressing the wire harness downwards in the accommodated state. With this structure, the position of the wire harness can be stabilized without deviation and accommodated within the gap between the plate-shaped portion and the main body. Furthermore, it can reliably prevent the reverse rotation of the rotating body.

[0026] The device includes a pad portion disposed within the gap between the pressing piece and the main surface, and clamped by the main surface and the accommodated wire harness in the accommodated state. According to this structure, the wire harness can be accommodated in the gap between the plate-shaped portion and the main body portion in a manner that protects the wire harness from the effects of unevenness formed on the main surface of the plate-shaped portion.

[0027] The rotating body can have a reverse rotation preventing part, which can prevent reverse rotation relative to the rotation that causes the upper part of the rotating body to face downwards, the lower part of the rotating body to face the gap side, and the pressing piece to face the main body side, before the wire harness is received. According to this structure, since the rotation of the rotating body to an unnecessary area can be prevented, damage caused by unnecessary rotation can be prevented.

[0028] The main body has a front end portion that is less rigid than the base end and thus more flexible. When the lower part of the rotating body is in the upward-pushing state, the front end portion of the main body can flex and deform together with the lower part of the rotating body. When a wire harness is accommodated in the gap between the plate-like part and the main body, the lower part of the rotating body needs to be pushed upward by the wire harness. If the structure is configured such that not only the lower part of the rotating body itself flexes and is pushed upward, but the front end of the main body also flexes and is pushed upward, it is easier to form an entry point for the wire harness into the gap. On the other hand, by setting the base end side to have high rigidity, a certain height of the gap can be reliably ensured. Attached Figure Description

[0065] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0066] like Figure 1 As shown, the wiring harness W layout structure 1 of the embodiment includes: a long strip-shaped wiring harness W; a plate-shaped member 100 (plate-shaped portion) disposed on the vehicle body; a main body 4, the base end of which is connected or snapped to the plate-shaped member 100 and extends along the main surface 100a of the plate-shaped member 100 toward the front end, capable of accommodating the wiring harness W from the front end of the main body 4 in a gap S provided between the main body 4 and the main surface 100a; and an anti-detachment portion 5, which prevents the wiring harness W accommodated in the gap S from detaching from the front end of the main body 4. The wiring harness W accommodated in the gap S is prevented from detaching at the front end of the main body 4 by the anti-detachment portion 5, which is configured as a rotating part that rotates with its accommodation, and is maintained in a state that prevents the anti-detachment portion 5 from rotating in the opposite direction. Furthermore, by a series of rotations accompanying the anti-detachment part 5, the part of the anti-detachment part 5 located at the highest position from the main surface 100a of the plate member 100 in the overall layout structure 1 (upper part of the rotating body 53) moves to a lower position, thereby forming an overall low-height layout structure 1.

[0067] The wiring harness W is a flexible wiring harness composed of multiple wires such as signal lines and power lines, and has a circular cross-section (see reference). Figure 5 The well-known wiring harness. In wiring harness W, such as... Figure 5 When the thickness (height) shown is larger than the height dimension h of the gap S, in forming the wiring structure 1 of the wire harness W, that is, when the wire harness W is accommodated in the gap S, it becomes a low-height state that is flattened and expands in the lateral width direction while its height is reduced (see reference). Figure 1 Furthermore, the wire harness W of the present invention is not limited to having a thickness (height) greater than the gap S; it can also be a wire harness with a height lower than the gap S. Additionally, the wiring structure 1 of the present invention is a structure that can accommodate long, strip-shaped wiring components such as flat cables and flat-plate wiring to replace the wire harness W.

[0068] First, using Figures 2 to 4 right Figure 1 The state of the wire harness W before its layout structure 1 is formed, before it is contained in the gap S, is explained.

[0069] exist Figure 1 In the arrangement structure 1, a clamping member 2, which integrally comprises a main body 4 and an anti-detachment part 5, is used. For example... Figure 3 As shown, the clamping member 2 integrally comprises a main body 4, an anti-detachment part 5, and a locking part 3 that inserts into and locks into a fixing hole 101 provided in the vehicle body. The clamping member 2 here is a resin injection molded body, which can hold the wire harness W by clamping it between the plate-shaped member 100 and the main body 4.

[0070] If the engaging portion 3 is inserted into the fixing hole 101, the elastic locking piece 31 is locked relative to the peripheral portion 102 of the fixing hole 101 from the deeper side of the insertion direction I, thus preventing it from falling out. Its peripheral portion 102 is clamped between the elastic locking piece 31 and the disc-shaped portion 32. As a result, the clamping member 2 is fixed to the plate-shaped member 100. In addition, the engaging portion 3 may not be formed in the center of the main body portion 4, but may be formed at a position offset to one end (the main body base end portion 4B side).

[0071] In the fixed state where the engaging portion 3 is inserted and fixed relative to the plate-shaped member 100, the main body portion 4 extends along the main surface 100a of the plate-shaped member 100 in the insertion direction I of the engaging portion 3, forming a gap S between the main body portion 4 and the main surface 100a. Figure 4 As shown, the main body 4 here has: a main body base end portion 4B, which extends from the bottom 3B of the engaging portion 3 (in the insertion direction I (refer to) Figure 3 The opposite end of the plate member 100 extends obliquely upward relative to the main surface 100a of the plate member 100; and the main body extension 4C extends from the main body base end 4B at a distance of a predetermined height h from the main surface 100a of the plate member 100 (see reference). Figure 5 It extends in parallel. In addition, the main body extension 4C can be shaped to form a gap S between itself and the main surface 100a, and does not have to be parallel to the main surface 100a.

[0072] In addition, such as Figure 4 As shown, the base end of the main body 4, which extends from the base end 4B to the extension 4C, has higher rigidity than the front end 4CA, which is located further forward. Here, the base end of the main body 4, where the rib 4L is formed, has higher rigidity, while the front end 4CA, where the rib 4L is not formed, has lower rigidity and is more prone to bending.

[0073] The anti-detachment part 5 integrally includes a rotating shaft part 500 connected to the front end side of the main body part 4 and a rotating body 50 connected to the rotating shaft part 500.

[0074] The rotating shaft portion 500 is the fulcrum for rotating the rotating body 50. It connects to the front end of the main body portion 4, forming a flexible connection portion that is most easily flexed within the entire clamping member 2. For example... Figure 4 As shown, the rotating shaft portion 500 is configured to extend in a straight line diagonally downwards from the front end of the main body portion 4 in the extending direction Y, and flexes and deforms within its length range. By generating this flexing and deformation, the rotating body 50 can be rotated. However, since the rotation is generated by flexing, the position of the rotation axis may slightly shift before, during, and after rotation depending on the state of flexing. Alternatively, the rotating shaft portion 500 can be set at a predetermined fixed position so that the rotating body 50 rotates around it without producing such a shift.

[0075] Furthermore, in this invention, rotating the rotating body 50 around the rotating shaft portion 500 includes cases where the rotating body 50 is rotated by arbitrarily generated deflection in the length direction of the rotating shaft portion 500, as in this embodiment, allowing for slight positional offset of the rotation axis that may occur at this time. On the other hand, it also includes cases where the rotation axis is set at a predetermined fixed position, and the rotating body 50 is rotated around the rotation axis at that fixed position.

[0076] The rotating body 50 integrally includes: a pressing piece 51 that extends from the rotating shaft portion 500 into the gap S; an anti-detachment piece 52 located at the front end of the main body portion 4 in the gap S; and an upper rotating body portion 53 located in the height direction Z from the main surface 100a of the plate member 100 at a position higher than the main body portion 4 and the rotating shaft portion 500.

[0077] The pressing sheet 51 is formed as an elastic sheet such that, in a fixed state relative to the plate-like member 100, it extends obliquely downward from the rotation shaft portion 500 toward the base end side of the main body portion 4, abutting or approaching the main surface 100a of the plate-like member 100, and extending linearly toward the base end side of the main body portion 4 in a manner that bends from there and is parallel to the main surface 100a. The bent portion 51B is formed with a thin wall, so that it is easier to flex than other sections in the length direction of the pressing sheet 51.

[0078] The anti-detachment piece 52 is formed as an elastic piece in the following way: when the clamping member 2 is fixed relative to the plate member 100, the elastic piece is located on the deeper side of the extension direction Y than the pressing piece 51, and extends obliquely downward from the deeper side of the extension direction Y toward the front side and abuts or approaches (here, abuts) the main surface 100a of the plate member 100 more than the rotating shaft portion 500.

[0079] The upper part 53 of the rotating body is formed here as a connecting part that connects the pressing piece 51 and the anti-detachment piece 52 at a higher position (upper side) in the height direction Z when fixed relative to the plate-shaped member 100. It is located at a position higher than the main body 4 and the rotating shaft 500. The upper part 53 of the rotating body extends obliquely upward from the rotating shaft 500 side of the pressing piece 51 toward the front end side (the deeper side in the extension direction Y) of the main body 4, reaching a position higher than the main body 4 and the rotating shaft 500 (upper side), and is connected to the anti-detachment piece 52 constituting the lower part of the rotating body on its lower side.

[0080] Furthermore, in the rotating body 50, the surface 5g from the upper part 53 of the rotating body to the anti-detachment piece 52, which is opposite to the gap S side, is set as a guide slope 5g that is inclined in a manner opposite to the main surface 100a. Here, the guide slope 5g is formed as a flat surface that descends obliquely downward from a position (upper side) higher than the main body part 4 and the rotating shaft part 500 at an acute angle relative to the main surface 100a.

[0081] Additionally, the rotating body 50 has a reverse rotation preventing part 54, which is in the state before the wire harness W is received (see reference). Figure 4 The reverse rotation prevents the upper part 53 of the rotating body from rotating downwards, the anti-detachment piece 52 from rotating towards the gap S, and the pressing piece 51 from rotating towards the main body 4. The reverse rotation preventing part 54 is provided in a form that protrudes from the upper part 53 of the rotating body, in a manner that is close to and opposite to the rotating shaft part 500 on the front end side of the main body 4 (the deeper side in the extension direction Y).

[0082] Next, using Figure 1 as well as Figures 5 to 7 right Figure 1 The steps for forming the wiring harness layout structure are explained.

[0083] like Figure 5 As shown, when the wire harness W is accommodated in the gap S, the wire harness W is pressed against the guide slope 5g towards the gap S, causing the rotating body 50 to rotate around the rotating shaft portion 500. Thus, the rotating body 50 rotates such that the upper part 53 of the rotating body faces downwards, the anti-detachment piece 52 faces the gap S side, and the pressing piece 51 faces the gap S side at an angle upwards. At this time, as... Figure 6 As shown, the wire harness W is deformed in a way that reduces its height by being flattened by the guide slope 5g, as... Figure 7 As shown, it enters between the anti-detachment piece 52 and the main surface 100a. At this time, the anti-detachment piece 52 is pushed upward in the form of flexural deformation (elastic deformation), thereby forming an inlet E into the gap S, through which the wire harness W can enter the gap S.

[0084] In addition, when the anti-detachment tablet 52 is in the pushed-up state (refer to...) Figure 7 When the main body 4 does not have ribs 4, the front end 4CA of the main body 4 can also flex and deform together with the anti-detachment piece 52. This ensures that the inlet E is in the height direction Z (refer to...). Figure 4 It is wider on top.

[0085] like Figure 6 as well as Figure 7 As shown, when the wire harness W enters the inlet E, it enters the lower side of the pressing plate 51, which rises towards the main body 4 due to the rotation of the rotating body 50. Therefore, even if the rotating body 50 were to rotate in the opposite direction (reverse rotation), the pressing plate 51 would come into contact with the wire harness W located on the side of its reverse rotation direction, thus preventing any degree of reverse rotation.

[0086] Furthermore, the pressing piece 51 here is maintained in a flexed state where its front end is pressed against the main body 4, causing the bending angle of the bent portion 51B to increase. Thus, the pressing piece 51 is maintained in a clamping state between the main body 4 and the wire harness W, and furthermore, the pressing piece 51 is maintained in a state of pressing the wire harness W downwards, preventing the rotating body 50 from rotating in the opposite direction.

[0087] like Figure 1 As shown, with the wire harness W fully contained within the gap S, the anti-detachment tab 52... Figure 7 The upward-pushing state shown is released (the upward-pushing state is lifted) and the device returns to the position that seals the inlet E of the entry gap S, forming an anti-detachment state for the contained wire harness W. On the other hand, the pressing plate 51 remains in the state where the wire harness W enters the lower side of the pressing plate 51, thus continuing the reverse rotation prevention state of the rotating body 50. As a result, the anti-detachment state of the wire harness W is maintained.

[0088] Furthermore, even in this containment state (refer to...) Figure 1 At this point, the pressing piece 51 also maintains a clamping state between the main body 4 and the wire harness W. In other words, the pressing piece 51 maintains a downward pressing state on the wire harness W, preventing the rotating body 50 from rotating in reverse and suppressing the positional displacement of the contained wire harness W.

[0089] Additionally, in this containment state (refer to...) Figure 1 Under these conditions, the upper part 53 of the rotating body, which has moved downwards due to the rotation of the rotating body 50 up to this point, remains at a position higher than when the rotation began (see reference). Figure 5The upper part 53 of the rotating body, which has moved downwards through the rotation up to this point, maintains a position in the height direction Z that is the same as or lower than one or both of the main body 4 and the rotating shaft 500 (lower side). Here, the upper part 53 of the rotating body is at a position higher than the highest position (rib 4L) of the main body 4 (height h0: refer to...). Figure 5 The state of the rotating body 50 is changed to a position lower than the highest position (rib 4L) (height h1: reference). Figure 7 It moves to a position almost at the same height as the rotating shaft 500. Therefore, Figure 1 The wiring harness W shown is arranged in a way that the clamping member 2 is lower in height than before it accommodates the wiring harness W (before the rotation of the rotating body 50 begins).

[0090] In addition, such as Figure 1 As shown, the highest position in the rotating body 50 in this accommodated state is the front end of the reverse rotation blocking part 54. This front end is also maintained at the same position as one or both of the main body 4 and the rotating shaft part 500 in the height direction Z, or at a position lower than one or both of them. In other words, by entering the aforementioned accommodated state, the entire rotating body 50, including the upper part 53 of the rotating body which is higher than the main body 4 and the rotating shaft part 500, becomes at the same height as at least one of the main body 4 and the rotating shaft part 500, or at a position lower than at least one of them, thus reducing the height of the clamping member 2.

[0091] Additionally, the wiring harness W here utilizes Figure 5 A wire harness with a thickness greater than the height dimension h of the gap S, but not greater than the height dimension h of the gap S, can also be arranged in a manner similar to that described above using the guide slope 5g, forming a layout structure that accommodates the gap S. However, when in the accommodated state, if the wire harness W has a certain thickness or more, it can form a reverse rotation prevention state that presses against the pressing plate 51 in the accommodated state. But if it does not have a certain thickness or more, although a reverse rotation prevention state based on the pressing plate 51 is formed, it may not be in the state of pressing against the pressing plate 51.

[0092] Thus, the wiring harness W layout structure 1 of the above embodiment (refer to...) Figure 1It includes: a main body 4, the base end of which is connected or engaged with a plate-shaped member 100 (plate-shaped part) provided on the vehicle body side, and the front end of which extends along the main surface 100a of the plate-shaped member 100, and is able to accommodate the wire harness W from the front end to the base end in the gap S formed between the main body 4 and the main surface 100a; and an anti-detachment part 5, which is provided on the front end of the main body 4, and is able to prevent the wire harness W accommodated in the gap S from detaching from the gap S. The anti-detachment part 5 integrally includes a rotating shaft part 500 connected to the main body part 4 and a rotating body 50 connected to the rotating shaft part 500. The rotating body 50 includes: a pressing piece 51 that extends from the rotating shaft part 500 into the gap S; an upper rotating body part 53 that extends from the rotating shaft part 500 in the opposite direction to the pressing piece 51 and is located above the rotating shaft part 500 in the height direction from the main surface 100a of the plate member 100; and a lower rotating body part (here, the anti-detachment piece 52) that is integrally connected to the upper rotating body part 53 and is located below the rotating shaft part 500. The surface 5g of the lower rotating body part (anti-detachment piece 52) that is opposite to the gap S from the upper rotating body part 53 is set as a guide slope 5g that is inclined in a manner opposite to the main surface 100a of the plate member 100. When a wire harness W with a thickness greater than the height of the gap S is inserted into the gap S, by pressing the wire harness W against the guide slope 5g, a rotation is generated in the rotating body 50 around the rotating axis 500, causing the pressing piece 51 to face the main body 4 in the gap S, the upper part of the rotating body 53 to face the main surface 100a of the plate member 100, and the lower part of the rotating body (anti-detachment piece 52) to face the inside of the gap S. As a result, the wire harness W enters between the lower part of the rotating body (anti-detachment piece 52) and the main surface 100a of the plate member 100 in a form that is flattened by the guide slope 5g and reduced in height. The lower part of the rotating body (anti-detachment piece 52) is pushed upward toward the pressing piece 51 so that it can enter into the gap S. During this entry, the wire harness W enters between the pressing piece 51 and the main surface 100a of the plate member 100, thereby preventing the rotation of the rotating body 50 about the rotation axis 500, which causes the pressing piece 51 to face the main surface 100a of the plate member 100. With the wire harness W contained in the gap S, the lower part of the rotating body (anti-detachment piece 52) is released from the above-mentioned upward push state and rotates back to the position that blocks the inlet E of the gap S, forming an anti-detachment state for the contained wire harness W. On the other hand, the pressing piece 51 is maintained in the state where the wire harness W enters the lower side of the pressing piece 51, thus continuing the reverse rotation prevention state of the rotating body 50. Furthermore, the upper part 53 of the rotating body is maintained at a lower position in the height direction Z than before the rotation started (at the beginning). Specifically, it is maintained at the same position as one or both of the main body part 4 and the rotating shaft part 500 in the height direction Z, or at a lower position than one or both of them.The above structure achieves a low-height layout of wire harness W.

[0093] The above describes one embodiment of the present invention, but this is merely an example. The present invention is not limited thereto. Various modifications, such as additions and omissions, can be made based on the knowledge of those skilled in the art, as long as they do not depart from the spirit of the claims.

[0094] Hereinafter, embodiments different from the above embodiments and variations thereof will be described. Furthermore, parts having common functions with the above embodiments will be labeled with the same reference numerals, and detailed descriptions will be omitted. Additionally, the above embodiments, the following variations, and other embodiments can be appropriately combined and implemented without causing technical inconsistencies.

[0095] In this invention, the gap S provided between the main body 4 and the main surface 100a does not necessarily mean that the main body 4 and the main surface 100a are directly sandwiched together by them. As long as it is a space formed within the interval between the main body 4 and the main surface 100a in the height direction Z that can accommodate the wire harness W, it is acceptable. For example, even if the main body 4 and the main surface 100a are divided vertically, as long as there is a gap S on either the upper or lower side, it is acceptable.

[0096] Furthermore, in this invention, when the engaging portion 3 is provided, its formation position can be set to a position where it connects to the main body portion 4. Moreover, this connection position becomes the base end portion of the main body portion 4.

[0097] Furthermore, in this invention, the plate-shaped member 100 (plate-shaped part), the engaging part 3, the main body part 4, the anti-detachment part 5, and further, the pad part 6 described later (see reference) Figure 8 as well as Figure 9 The structural elements of the arrangement structure 1, such as the main body 4, the anti-detachment part 5, and the rotating shaft part 500, can exist as independent components or be integrated as a whole. For example, it can be a structure that can be freely assembled by engaging and locking the main body 4, the anti-detachment part 5, and the rotating shaft part 500.

[0098] The plate-shaped portion in this invention is a plate-shaped portion provided on the side of the vehicle body. In this sense, it is not only a plate-shaped portion provided on the vehicle body like the plate-shaped member 100 in the above embodiment, but also a plate-shaped portion of a part assembled on the vehicle body or a plate-shaped portion of a part to be assembled on the vehicle body (e.g., a protective member for a component that protects wiring, a door trim member for an inner lining component on the inside of a door, etc.).

[0099] use Figure 8 as well as Figure 9A first variation of the above embodiment will be described. In the first variation, the wiring structure 1 of the wire harness W includes a pad portion 6 disposed within the gap S between the pressing piece 51 and the main surface 100a. This pad portion 6 is located in a position where it is held between the main surface 100a and the accommodated wire harness W in the receiving state. Figure 9 As shown, in the first modified example, the pad portion 6 extends from the base end 4B of the main body toward the gap S and is arranged to be placed on the main surface 100a. When the wire harness W enters the gap S, the wire harness W, which pushes the anti-detachment piece 52 upward, rises from the main surface 100a toward the pad portion 6 and is accommodated in the gap S in the risen state.

[0100] use Figure 10 as well as Figure 11 A second variation of the above embodiment will be described. In the second variation, the wiring structure 1 of the wire harness W is configured such that the engaging part 3 is omitted, and the main body 4 and the anti-detachment part 5 constitute part of the plate-shaped member 100 (plate-shaped part). In this case, the main body 4 can be configured as a member that is fixed and integrated with the plate-shaped member 100 by welding or fusion, and there is no member independent of the plate-shaped member 100, such as the clamping member 2. In the case of the second variation, the main body 4 is configured such that its base end side (4B) is connected to the plate-shaped member 100, it stands upright from the plate-shaped member 100 and bends at its front end, extending along the main surface 100a of the plate-shaped member 100 toward the front end side.

[0101] use Figure 12 as well as Figure 13 A third variation of the above embodiment will be described. In the third variation, the main body 4 of the wiring structure 1 of the wire harness W is shaped like an inverted U. One straight section of the U and the bottom of the U (the left end of the main body 4 in the figure) are located on the main surface 100a side of the plate member 100 (plate part) as the main body base end 4B of the main body 4. The other straight section, which extends from the bottom of the U opposite to it, extends along the main surface 100a as the main body extension 4C of the main body 4. An anti-detachment part 5 is provided at the front end of the main body extension 4C. Furthermore, the main body base end 4B constituting one of the straight sections of the U also functions as the pad part 6 in the first variation, becoming a part that bears the functions of both.

[0102] In the above embodiments and variations, the figures illustrating the examples are schematic representations to a certain extent. In particular, the number, configuration, arrangement, and cross-sectional shape of the wiring within the harness W are depicted in an overly orderly manner, but are not necessarily accurately depicted.

Claims

1. A wiring harness layout structure, characterized in that, The wiring harness layout structure includes: The main body has its base end connected or snapped to a plate-shaped part disposed on the side of the vehicle body, and its front end extends along the main surface of the plate-shaped part, so that the wire harness can be accommodated from the front end to the base end in the gap formed between the main body and the main surface; as well as An anti-detachment part, located at the front end of the main body, prevents the wire harness contained within the gap from detaching from the gap. The anti-detachment part integrally includes a rotating shaft portion connected to the main body portion and a rotating body connected to the rotating shaft portion. The rotating body has: The pressing plate extends from the rotating shaft into the gap; The upper part of the rotating body extends from the rotating shaft in the opposite direction to the pressing piece and is located above the rotating shaft in the height direction from the main surface of the plate-shaped part. as well as The lower part of the rotating body is integrally connected to the upper part of the rotating body and is located lower than the rotating shaft. The surface extending from the upper part of the rotating body to the lower part of the rotating body, opposite to the gap, is configured as a guide slope inclined in a manner opposite to the main surface of the plate-shaped part. When a wire bundle with a thickness greater than the height of the gap is inserted into the gap, by pressing the wire bundle against the guide slope, a rotation is generated in the rotating body around the rotation axis, causing the pressing plate to face the main body side within the gap, the upper part of the rotating body to face the main surface side of the plate-like part, and the lower part of the rotating body to face the inside of the gap. As a result, the wire bundle enters between the lower part of the rotating body and the main surface of the plate-like part in a manner that is flattened and reduced in height by the guide slope. The lower part of the rotating body is then pushed upwards towards the pressing plate side, allowing it to enter the gap. Upon entry, the wire harness enters between the pressing piece and the main surface of the plate-like portion, thereby preventing the rotation of the rotating body about the rotation axis from causing the pressing piece to face the main surface of the plate-like portion. When the wire harness is contained within the gap, the lower part of the rotating body is released from the upward pushing state towards the pressing plate and returns to the position of blocking the inlet into the gap, forming an anti-detachment state for the contained wire harness. On the other hand, the pressing plate remains in a state where the wire harness has entered the lower side of the pressing plate, thus continuing the reverse rotation prevention state of the rotating body. Furthermore, through the rotation of the rotating body up to this point, the upper part of the rotating body remains at a position lower than the position at the beginning of the rotation.

2. The wiring harness layout structure according to claim 1, characterized in that, The pressing tab remains in the receiving state to press the wire harness downwards.

3. The wiring harness layout structure according to claim 1, characterized in that, The wiring harness layout structure includes a pad portion, which is disposed within the gap between the pressing piece and the main surface, and is clamped by the main surface and the accommodated wiring harness in the accommodated state.

4. The wiring harness layout structure according to claim 1, characterized in that, The rotating body has a reverse rotation preventing part, which can prevent reverse rotation relative to the rotation that causes the upper part of the rotating body to face downward, the lower part of the rotating body to face the gap side, and the pressing piece to face the main body side before the wire harness is received.

5. The wiring harness layout structure according to claim 1, characterized in that, The main body has a front end portion that is less rigid than the base end and is more easily flexed. When the lower part of the rotating body is in the upward pushing state, the front end portion of the main body can flex and deform together with the lower part of the rotating body.
