[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2004-236447 Summary of the Invention

[0006] Problems to be solved by the invention

[0007] However, a wiring harness is a bundle of multiple wires, including signal lines and power lines, bound and held together with tape or the like, and having a generally circular cross-section. While such wiring harnesses are widely used in current vehicles, in recent years, there has been a desire for a structure that allows them to be laid out at a lower height to ensure greater interior space.

[0008] To address this, Patent Document 1 describes a wiring structure that flattens a wire harness to achieve a lower profile. However, currently, a single wire clip is desired to extend over a longer length of the wire harness, thereby lowering the height of the wire harness. Therefore, one approach is to extend the portion of the wire clip that holds the wire harness longer along the length of the harness. However, simply extending the length only results in increased material consumption and waste.

[0009] An object of the present invention is to realize a new wire harness bundling structure that allows a wire harness having a circular cross section to be stably lowered over a wider range in its longitudinal direction with less waste.

[0010] Means for solving the problem and effects of the invention

[0011] A wire harness bundling structure for solving the above-mentioned problem comprises a wire harness, a wire clamp, and a bundling member, wherein the wire harness has a circular cross-section, the wire clamp has an engaging portion for mounting on a vehicle body, and holds the wire harness in a manner such that the wire harness is flattened and spread out in a lateral width direction to reduce its height, and the bundling member holds and bundles the held wire harness and a portion of the wire clamp.

[0012] It is characterized by:

[0013] The wire clamp has:

[0014] a plate-shaped placement portion having a placement surface on which the wire harness is placed and having a width in the lateral direction wider than that of the wire harness; and

[0015] The pressing portion includes a pair of pressing main bodies and opposing extensions, wherein the pair of pressing main bodies extend across the wire harness placed on the placing surface and are arranged opposite to each other in the longitudinal direction thereof, and can press and clamp the wire harness against the placing surface so that the wire harness is spread out on the placing surface in the transverse direction to achieve a low height state in which its height is reduced, and the opposing extensions extend from the pair of pressing main bodies in a manner close to each other.

[0016] The binding member binds the placing portion and the opposed extending portions together with the wire harness in the low-height state between the opposed portions of the pair of pressing main bodies.

[0017] According to the structure of the present invention described above, the wire harness is pressed against the loading surface by the bundling member and the two pressing bodies, thereby being spread out in the lateral width direction and reducing its height (a flattened state). This low-height state is maintained by the bundling force of the bundling member. This allows the low-height state of the wire harness to be formed and maintained widely across a long area, including the pressing sections of the two pressing bodies and the bundling section formed therebetween by the bundling member. Furthermore, since only opposing extensions are formed between the opposing portions of the two pressing bodies, the pressing portion is not simply formed wide in the longitudinal direction of the wire harness, but is instead formed in a shape that eliminates unnecessary portions. Furthermore, the bundling force of the bundling member that maintains the low-height state, i.e., the pressing force of the bundling member that presses the wire harness against the loading surface, is effectively transmitted to the two pressing bodies via the opposing extensions.

[0018] Furthermore, in the structure of the present invention described above, if the bundling component is a tape component having an adhesive surface provided on one main surface, the structure of bundling the opposing extension portions between the opposing portions of the two pressing main bodies can make the bonding area between the tape component and the wiring harness wider in the lateral width direction during bundling, thereby also preventing the wiring harness from shifting in its longitudinal direction.

[0019] Furthermore, the wiring harness of the present invention is a wiring bundle composed of multiple wires and having a circular cross-section, which differs from a wiring harness that is pre-determined to be low in height, such as flat cables or planar wiring. However, while the wiring harness bundling structure of the present invention does not include the use of flat cables or planar wiring in place of the wiring harness, it does not necessarily preclude their use.

[0020] The cable clamp includes a temporary assembly unit that temporarily assembles the pressing portion and the loading portion, which hold the low-profile wire harness, into a temporary assembled state; and a height-changing unit that can change the height from the loading surface to the pressing portion. By bundling the loading portion and the opposing extension portion with the low-profile wire harness in the temporary assembled state using the bundling member, the height-changing unit can be set to a state in which height-changing is prohibited. With this structure, the low-profile (flattened) state can be easily achieved and maintained by sandwiching a circular-cross-section wire harness between the loading and pressing portions of the cable clamp. Furthermore, the temporary assembled state facilitates subsequent bundling operations using the bundling member. Furthermore, the height-changing unit allows the height of the space between the pressing portion and the loading portion to be varied, thereby facilitating temporary assembly operations. Furthermore, the variable height allows for handling wire harnesses of varying thicknesses. Furthermore, the binding of the binding member inhibits the harness from changing height, and the binding force maintains the harness at its lowest possible height. In other words, the harness is not deformed to a predetermined lower height, but rather deformed to the lowest possible height and maintained in that state.

[0021] The height changing unit has a flexible connecting portion connecting the carrier portion and the pressing portion at one end side in the transverse direction, and the temporary assembly unit has an assembly portion assembling the carrier portion and the pressing portion at the other end side in the transverse direction. Through this assembly, the wire harness in the low-height state sandwiched between the carrier portion and the pressing portion can be maintained so as not to fall off the carrier surface. According to this structure, since the pressing portion and the carrier portion are connected at one end side and assembled at the other end side, the temporary assembly state can be easily formed by rotating the pressing portion with the connected one end side as a rotation fulcrum so that the other end approaches the carrier portion, and the simultaneous lowering of the pressing wire harness also becomes easier.

[0022] The opposing extension portions may constitute a bridge portion connecting the pair of pressing portions disposed opposite to each other in the longitudinal direction. According to this configuration, the pressing portion having two pressing main bodies is formed of a single component, thereby facilitating temporary assembly work.

[0023] The pressing portion may include a biting portion that protrudes further toward the loading surface than the pressing surface of the main pressing portion that presses the wire harness. This configuration allows the biting portion of the pressing portion to bite into the wire harness in the provisionally assembled state, pressing the wire harness more strongly against the loading portion. Furthermore, the wire harness in the aforementioned low-profile state is held in place by the biting portion, thereby preventing it from shifting in the lateral width direction.

[0024] The outer surface of the opposing extension, located on the side opposite the inner surface that presses the wire harness, is located at the same height as the surface of the pressing body portion's pressing surface on the wire harness, located on the opposing extension's side in the transverse direction. For example, the outer surface of the opposing extension can be located on a continuous surface (e.g., coplanar with the pressing surface) that extends from the pressing body portion's pressing surface on the wire harness. With this configuration, the height of the wire harness bundling structure does not increase in the area where the bundling member passes over the opposing extension, thereby contributing to a lower height. Furthermore, considering the case where the outer surface of the opposing extension is located further away from the loading surface than the pressing surface of the pressing body portion, when a bundling member with an adhesive surface formed on its back, such as a tape, is wound around it, the bundling member will adhere (closely contact) to the outer surface of the opposing extension, but will not adhere to the outer surface areas of the wire harness adjacent to it, causing it to float. According to the above-mentioned structure, the bundling component can be adhered (closely attached) to such an outer surface area without floating, and a more secure bundling and holding can be achieved. In addition, the outer surface of the opposing extension portion can be located at a lower position in the height direction relative to the surface of the end portion of the pressing surface of the pressing body portion that is located on the side of the opposing extension portion in the horizontal width direction. In this case, the bundling component with an adhesive surface formed on the back side, such as a tape, can be adhered at least to the outer surface of the wire harness without floating, so that a secure bundling and holding can be achieved. These structures that form the outer surface of the opposing extension portion at the same level as the pressing surface of the pressing body portion or at a height lower than the same level also form the above-mentioned biting portion, so that the effects of both can be achieved at the same time, which is more convenient.

[0070] Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

[0071] like Figure 1 as well as Figure 2 As shown, the wire harness bundling structures 1A and 1B of the first embodiment include a wire harness W (see Figure 5 as well as Figure 10 ), a wire clamp 2 and a bundling component 10, the wire harness W has a circular cross-section, the wire clamp 2 has a snap-fit ​​portion 3 for mounting on the vehicle body, on the other hand, the wire clamp 2 holds the wire harness W in a form of flattening the wire harness W and spreading it in the transverse width direction Y to reduce its height, and the bundling component 10 bundles and holds the wire harness W held by the wire clamp 2 and a portion of the wire clamp 2.

[0072] The wiring harness W is a flexible wiring harness composed of a plurality of wirings such as signal lines and power lines, and has a circular cross section (see FIG. Figure 5 as well as Figure 10 ) of the known wire harness, when forming the bundled structure 1A, 1B of the wire harness, the wire harness W is flattened and expanded in the lateral width direction, becoming a low height state with a reduced height (refer to Figure 1 as well as Figure 2 The wire harness W of the present invention is different from a wire harness that has a low height before forming the above-mentioned bundling structure, such as a flat cable or a flat-plate wiring.

[0073] In addition to the above-mentioned engaging portion 3, the wire clamp 2 also includes Figure 3 As shown, a placement portion 4, a pressing portion 5, a connecting portion 6, and an assembly portion 7 are also integrally provided.

[0074] like Figure 4 As shown, the engaging portion 3 is inserted into and locked in a fixing hole 101 provided in the vehicle body, and is formed to protrude from the back surface 4s behind the loading surface 4p of the loading portion 4. When the engaging portion 3 is inserted into the fixing hole 101, it engages the elastic locking piece 31 from the inner side of the insertion direction I toward the peripheral portion 102 of the fixing hole 101, thereby preventing it from coming out. The peripheral portion 102 is fixed between the elastic locking piece 31 and the disc-shaped portion 32.

[0075] In addition, if Figure 1 and Figure 2 As shown, the engaging portion 3 is on the back side 4s of the mounting portion 4 (see Figure 3 ) is formed at a position offset to one side in the longitudinal direction X from the bundling position (bundling section) 10X of the bundling member 10.

[0076] like Figure 5 as well as Figure 10 As shown, the loading portion 4 is formed into a flat plate having a loading surface 4p, and the loading surface 4p loads the wire harness W having a circular cross section. The loading surface 4p is a flat surface, and is formed to have a dimension in the lateral width direction Y that is wider than the wire harness W having a circular cross section. Figure 3 As shown, the placement surface 4p is formed so that the dimension in the longitudinal direction X of the wire harness W is wider than the lateral dimension thereof.

[0077] In the following, the longitudinal direction of the wire harness W placed on the placement surface 4p is referred to as the longitudinal direction X, the vertical direction relative to the placement surface 4p is referred to as the height direction Z, and the width direction of the placement surface 4p and the wire harness W, which are perpendicular to these directions, is referred to as the transverse direction Y. Here, the placement surface 4p is located on a plane parallel to a plane including the longitudinal direction X and the transverse direction Y.

[0078] The pressing portion 5 Figure 5 as well as Figure 10 The wire harness W having a circular cross section on the mounting surface 4p shown is as shown in FIG. Figure 6 as well as Figure 11 As shown in FIG. 4 , the pressing portion 5 is pressed against the loading surface 4p. Thus, the pressing portion 5 can set the wire harness W to a low height state (flat state) in which its height is reduced by spreading it out along the lateral width direction Y on the loading surface 4p. Figure 3 As shown, the pressing portion 5 here integrally includes pressing main body portions 50 , 50 and opposing extending portions 51 , 52 .

[0079] like Figure 8 and Figure 13 As shown, the main body parts 50, 50 are pressed to be placed on the placement surface 4p (refer to Figure 6 as well as Figure 11 ) are arranged in pairs in a manner opposite to each other in the longitudinal direction X of the harness W, and are each in the shape of a flat plate thinner than the mounting portion 4. The main body portions 50, 50 are pressed to cross the harness W having a circular cross section on the mounting surface 4p (refer to Figure 5 、 Figure 10 ) is configured in the form of a , and the wire harness W can be pressed in the form of being sandwiched between it and the mounting portion 4 to be set to the above-mentioned low height state (flat state).

[0080] In addition, the pressing body parts 50, 50 here have lower rigidity than the placing part 4 and have flexibility. Figure 11 As shown, the pressing body portions 50 , 50 are capable of bending along the outer surface of the wire harness W in the extending direction thereof.

[0081] like Figure 3 As shown, the facing extension portions 51, 52 extend from the pair of pressing body portions 50, 50 so as to approach each other. Here, the facing extension portions 51, 52 constitute a bridge portion connecting the pair of pressing body portions 50, 50 in the longitudinal direction X.

[0082] like Figure 8 and Figure 13As shown, the opposing extension portion 51 is provided so as to extend along the longitudinal direction X from a portion of the entire extension direction (lateral width direction Y) of the pair of pressing main bodies 50, 50. Here, the opposing extension portion 51 is offset toward one end side (YA) of the pair of pressing main bodies 50, 50 in the lateral width direction Y. More specifically, the opposing extension portion 51 is provided at the end portion of the one end side (YA), and can press the wire harness W on the placement surface 4p against the placement surface 4p together with the pressing main bodies 50, 50.

[0083] In addition, if Figure 3 As shown, the pressing portion 5 has a bite portion 51V that protrudes further toward the placement surface 4p than the pressing surface 50p of the wire harness W on the pressing body portion 50, 50. Figure 14 As shown, when the pressing body parts 50, 50 press the harness W on the loading surface 4p onto the loading surface 4p, the biting part 51V can bite into the harness W. The biting part 51V here is formed by pressing the main body parts 50, 50 on both sides of the opposing extension part 51 along the longitudinal direction X (refer to Figure 3 )Extended form settings.

[0084] In addition, if Figure 7 and Figure 12 As shown, the outer surface 51s of the opposing extension portion 51 on the side opposite to the inner surface (bite portion 51V) on the side pressing the wire harness W is aligned with the surface 50p1 of each pressing surface 50p of the pressing main body 50, 50 at the end portion on the opposite extension portion 51 side in the transverse width direction Y (see FIG. Figure 6 and Figure 11 ) are located at the same position (height). Here, the outer surface 51s and the surface 50p1 are located on the same plane F. Further, Figure 7 In the embodiment, the outer surface 51s and the pressing surfaces 50p are located on the same plane F. Figure 12 In the embodiment, the outer surface 51s and the pressing surfaces 50p are located on the same continuous surface R that is smoothly continuous.

[0085] like Figure 6 and Figure 11 As shown, the opposite extension portion 52 (refer to Figure 3 ) The other end side (YB) of the pair of pressing main body parts 50, 50 in the transverse direction Y is provided on the outer side of the transverse direction Y of the harness W on the placing surface 4p, as shown Figure 3 As shown, the facing extension portion 52 includes a pressing portion side engaging portion 75 described later at the center of the facing extension portion 52 in its own extending direction (longitudinal direction X).

[0086] like Figure 3As shown, the connecting portion 6 connects the loading portion 4 and the pressing portion 5 at one end side (YA) in the transverse width direction Y. The connecting portion 6 here is respectively provided corresponding to the paired pressing body portions 50, 50, and is provided so as to be connected to the loading portion 4. The connecting portion 6 has flexibility so as to be able to change the height from the loading portion 4 (loading surface 4p) to the pressing portion 5 at one end side (YA) in the transverse width direction Y. Specifically, the connecting portion 6 has one or more flexible portions that are more easily flexible than other portions in the longitudinal direction from the loading portion 4 to the pressing portion 5, so that the change in height from the loading portion 4 to the pressing portion 5 is greater at one end side (YA) in the transverse width direction Y than at the other end side (YB).

[0087] like Figure 7 and Figure 12 As shown, when the connecting portion 6 is temporarily assembled, the bending portion 6C is mainly bent. However, the connecting portion 6 can be bent in all sections in the longitudinal direction. As a result, the pressing portion 5 (pressing surface 50p) can be bent in the transverse width direction Y (refer to Figure 6 and Figure 11 ) changes to a higher position in the height direction Z from the mounting surface 4p (a position farther from the mounting surface 4p) compared to its position at the other end side (YB).

[0088] In addition, if Figure 7 as well as Figure 12 As shown, the flexible portion 6C (first flexible portion) is formed in the middle section (here, the curved section) from the placement section 4 to the pressing section 5 of the connecting portion 6. In the entire section from the placement section 4 to the pressing section 5, the flexible portion 6C is most easily flexible due to its thin wall.

[0089] In addition, when the connecting portion 6 is not loaded (not deformed), Figure 5 and Figure 10 As shown, the connecting portion 6 extends outward from the receiving portion 4 in the transverse direction Y (one end side (YA)), bends at its front end in the height direction Z, and connects to the pressing portion 5, forming an overall L-shaped shape. The connecting portion 6 is connected to the receiving portion 4 in a substantially straight line in the substantially transverse direction Y, and is also connected to the pressing portion 5 in a substantially straight line in the height direction Z.

[0090] like Figure 6 and Figure 11As shown, the assembly portion 7 can be set to a temporary assembly state in which the loading portion 4 and the pressing portion 5 are assembled at the other end side (YB) in the transverse width direction Y. Through this assembly (temporary assembly state), the wire harness W in a low-height state sandwiched between the loading portion 4 and the pressing portion 5 can be maintained in this low-height state so as not to fall off the loading surface 4p. The assembly portion 7 here includes a pressing portion side locking portion 75 provided on the pressing portion 5 at the other end side (YB) in the transverse width direction Y, and a loading portion side locking portion 74 provided on the loading portion 4. These locking portions 74 and 75 form a temporary assembly state in a form in which they are always locked to each other.

[0091] The pressing portion side locking portion 75 is Figure 6 and Figure 11 In the provisionally assembled state shown, the other end side (YB) in the transverse direction Y extends from the pressing portion 5 toward the receiving portion 4, and a locking claw is formed at its front end, protruding toward the one end side (YA). Meanwhile, the receiving portion-side locking portion 74 protrudes from the receiving portion 4 toward the pressing portion 5 in the provisionally assembled state described above at the other end side (YB) in the transverse direction Y, and a locking claw is formed at the other end side (YB) in the transverse direction Y, which is positioned higher in the height direction Z than the pressing portion-side locking portion 75.

[0092] The tying member 10 is positioned between the opposing portions of the pair of pressing main bodies 50, 50. Figure 9 and Figure 14 As shown, the mounting portion 4 and the opposing extension portion 51 are bundled with the wire harness W so that Figure 8 and Figure 13 The placing portion 4 (placement surface 4p (refer to Figure 9 and Figure 14 The wire harness W, which is pressed by the pressing portion 5 and lowered to a lower height, is pressed by the pressing portion 5 to an even lower height. The bundling member 10 is a flexible, long strip-shaped member thinner than the pressing body 50, 50, and is a tape member having an adhesive surface on the side facing the bundling object (the inner peripheral surface when wound around the bundling object).

[0093] use Figures 5 to 9 and Figures 10 to 14 illustrate Figure 1 and Figure 2 The formation order of the bundling structure of the wire harness.

[0094] First, if Figure 5 and Figure 10 As shown, the wire harness W having a circular cross section is placed on the placement surface 4 p of the placement portion 4 .

[0095] Next, if Figure 6 and Figure 7 and Figure 11 and Figure 12As shown, the pressing portion 5 is tilted so that the connecting portion 6 (mainly the flexure 6C) is bent and deformed, pressing the wire harness W on the placement surface 4p against the placement surface 4p. As a result, the wire harness W having a circular cross-section is sandwiched between the pressing portion 5 and the placement portion 4, spreading out along the transverse direction Y on the placement surface 4p to a reduced height (flattened state).

[0096] At this time, the pressing portion side locking portion 75 is looped under the placing portion side locking portion 74 to be locked, thereby achieving a temporary assembled state in which the placing portion 4 and the pressing portion 5 are assembled. As a result, the wire harness W is annularly surrounded in the aforementioned low-height state, and is held so as not to fall out between the placing portion 4 and the pressing portion 5.

[0097] Furthermore, when the pressing portion 5 is tilted, the connecting portion 6 is bent, thereby increasing the height of the one end side (YA) in the lateral direction Y. This allows the pressing portion side locking portion 75 to move deeper toward the other end side (YB) in the lateral direction Y, allowing the pressing portion side locking portion 75 to be moved around to the lower side of the placement portion side locking portion 74, thereby achieving the aforementioned locked state (temporarily assembled state).

[0098] In addition, Figure 6 In the temporary assembly state, since the diameter of the wire harness W is small, the biting portion 51V is in contact with the loading surface 4p. This contact state is a state in which an external force is intentionally and continuously applied to press the pressing portion 5 downward. When the external force is removed, the deflection of the flexure 6C is eliminated, and the loading portion 4 and the pressing portion 5 are separated at one end side (YA) in the transverse width direction Y. If the connecting portion 6 is further bent as a whole, the loading portion 4 and the pressing portion 5 can be further separated at one end side (YA). That is, Figure 6 The provisional assembly state is a state in which the height from the placement portion 4 (placement surface 4 p ) to the pressing portion 5 can be changed at one end side (YA) in the transverse direction Y by bending the connecting portion 6 .

[0099] On the other hand, Figure 11 In the case of the temporary assembly state, since the diameter of the wire harness W is large, the bite portion 51V abuts against the wire harness W and does not abut against the loading surface 4p. When the connection portion 6 is bent in the temporary assembly state (locked state), it cannot return to the position in which it is in contact with the wire harness. Figure 10 The same state is maintained, but the bending state is maintained, and the bending portion 6C is maintained in a state where the height of the pressing portion 5 relative to the loading portion 4 can maintain the temporary assembly state (it can also be not bent). In this state, by applying an external force to press the pressing portion 5 downward, the biting portion 51V can bite into the wire harness W in the form of bending the connecting portion 6, and the pressing surface 50p is brought into contact with the wire harness W. That is, Figure 11The provisional assembly state is also a state in which the height from the placement portion 4 (placement surface 4 p ) to the pressing portion 5 can be changed at one end side (YA) in the transverse direction Y by bending the connection portion 6 .

[0100] In addition, Figure 11 In the temporary assembly state, the pair of pressing main body parts 50, 50 are in a state of bending in the form of close contact with the outer surface of the wire harness W in their respective extension directions. This deformation also helps Figure 11 In the provisional assembly state, the height from the placement portion 4 (placement surface 4p) to the pressing portion 5 is changed at one end side (YA) in the transverse direction Y.

[0101] In this way, Figure 6 and Figure 11 In the temporary assembly state shown, due to the bending of the connecting portion 6 and the pressing body portions 50, 50, the height from the placing portion 4 (placing surface 4p) to the pressing portion 5 can be changed at one end side (YA) in the transverse direction Y. Figure 9 and Figure 14 ) The placing portion 4 and the opposing extension portions 51, 52 are strongly bundled with the wire harness W between the opposing portions of the pair of pressing main bodies 50, 50 to prevent the height change. By bundling, the height change between the placing portion 4 and the pressing portion 5 is prevented while the wire harness W is kept in close contact with the placing portion 4 and the pressing portion 5. As a result, a Figure 1 and Figure 2 The bundled structures 1A and 1B of the wire harness W are shown.

[0102] like Figure 9 As shown, Figure 1 The bundling structure 1A is in a state where the bite portion 51V contacts the loading surface 4p and the height from the loading portion 4 to the pressing portion 5 is at its lowest. Since the outer surface 51s of the opposing extension portion 51 and the pressing surface 50p of the pressing body portion 50, 50 are located on the same plane F, the bundling member 10 is in a bundling state in which the outer surface 51s of the opposing extension portion and the outer surface of the wire harness W are bonded in a straight line. Figure 5 The wire harness W having a circular cross-section is in a state of minimum height.

[0103] like Figure 14 As shown, Figure 2The bundling structure 1B is in a state where the biting portion 51V further bites into the wire harness W and presses the pressing surfaces 50p of the main body portions 50, 50 to press the wire harness W, and the height from the placement portion 4 to the pressing portion 5 is maintained at a lower level. Since the outer surface 51s of the opposing extension portion 51 and the base end side region 50p1 of the pressing surfaces 50p, 50p are located on substantially the same plane F, the bundling member 10 adheres the outer surface 51s of the opposing extension portion 51 and the outer surface of the wire harness W so that the two are linearly continuous. Furthermore, the portions of the pressing surfaces 50p, 50p that are closer to the front end side (the other end side (YB) in the transverse width direction Y) than the base end side region 50p1 are continuous to the region 50p2 that is smoothly curved in a continuous form from the base end side region 50p1 and the region 50p3 that is flatly inclined further forward, and the outer surface of the wire harness W pressed by these surfaces also becomes the same continuous surface R as these surfaces, so the above-mentioned bundling component 10 is bonded to the outer surface of the wire harness W that is pressed by these surfaces 50p1, 50p2, 50p3 and is located on the same continuous surface R as these surfaces. That is, the bundling component 10 is in a bundling state in which it is bonded without steps across the outer surface 51s of the opposing extension portion 51 and the outer surface of the wire harness W that is smoothly continuous from this outer surface 51s. By this bundling state, the outer surface of the wire harness W is maintained. Figure 10 The wire harness W having a circular cross-section is in a state of minimum height.

[0104] In addition, in the first embodiment, the above-mentioned assembly portion 7 functions as a temporary assembly unit that puts the pressing portion 5 and the loading portion 4 that clamp the wire harness W in a low-height state into a temporary assembly state, and the above-mentioned connecting portion 6 functions as a height changing unit that can change the height from the loading surface 4p to the pressing portion 5.

[0105] Furthermore, in the bundling structures 1A and 1B of the first embodiment, the height changing unit (connecting portion 6) is located outside the wire harness W placed on the placement surface 4p in the transverse direction Y, and more specifically, outside the placement surface 4p in the transverse direction Y. Therefore, the height changing unit itself does not contribute to an increase in the height of the bundling structures 1A and 1B. The temporary assembly unit (assembly portion 7) is also located outside the wire harness W placed on the placement surface 4p in the transverse direction Y, and more specifically, outside the placement surface 4p in the transverse direction Y. Therefore, the temporary assembly unit itself does not contribute to an increase in the height of the bundling structures 1A and 1B.

[0106] In addition, in the bundling structures 1A and 1B of the first embodiment, as Figure 4 As shown, the binding member 10 (see FIG. 1 ) is pressed between the main body portions 50 and 50 on the back side 4s of the placement portion 4. Figure 9 and Figure 14) is formed in the bundling area, with protrusions 4T (ribs) extending in the transverse direction Y. The bundling member 10 constituting the tape member is bonded to the protrusions 4T. The protrusions 4T are formed in a plurality (here, three) in the longitudinal direction X, thereby increasing rigidity compared to other areas and preventing the receiving portion 4 from deflecting due to the bundling force of the bundling member 10.

[0107] While one embodiment of the present invention has been described above, this is merely an example and 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 without departing from the scope of the claims.

[0108] The following describes embodiments that differ from the above-described embodiment and variations of these embodiments. Parts that share the same functions as the above-described embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted. The above-described embodiment, the following variations, and other embodiments may be implemented in appropriate combinations within the scope of not creating technical conflicts.

[0109] For example, the connecting portion 6 and the assembling portion 7 may be omitted, and the placing portion 4 and the pressing portion 5 may be separated.

[0110] In addition, the opposing extension portions 51 only need to extend from the pair of pressing main body portions 50 in a manner close to each other, such as Figure 22 As shown in the modified example, it is not necessary to connect them. In addition, the pair of pressing main body parts 50 only needs to have one or more opposing extension parts. For example, Figure 23 As shown in the modified example, the opposing extension portion 51 may be omitted, and only the opposing extension portion 52 may be provided. Furthermore, the outer surface 51s of the opposing extension portion 51 may be positioned lower in the height direction Z than the surface of the end portion of the main body 50, 50 located on the opposing extension portion 51 side in the transverse direction Y, which presses against the wire harness W. In this case, the binding member 10, such as an adhesive tape, whose back surface forms the adhesive surface, can be bonded to at least the outer surface of the wire harness W without lifting.

[0111] The binding member 10 may be a band-like member such as a binding tape instead of a tape member. However, considering its thickness (height), a tape-like member is preferable.

[0112] Hereinafter, a second embodiment of the present invention will be described with reference to the accompanying drawings.

[0113] As in the first embodiment, Figure 15As shown, the wire harness bundling structure 1C of the second embodiment also includes a wire harness W, a wire clamp 2, and a bundling member 10. The wire harness W has a circular cross-section, and the wire clamp 2 has an engaging portion 3 for mounting to a vehicle body. On the other hand, the wire clamp 2 holds the wire harness W in a manner such that the wire harness W is flattened and spread out in the transverse direction Y to reduce its height. The bundling member 10 bundles and holds the wire harness W held by the wire clamp 2 and a portion of the wire clamp 2.

[0114] The wire harness W and the binding member 10 are the same as those in the first embodiment. Figure 16 In the wiring clip 2 shown, the pressing body parts 50, 50 of the pressing part 5 have higher rigidity than those in the first embodiment and are less likely to bend.

[0115] like Figure 16 As shown, the connecting portion 6 is provided at one end side (YA) in the transverse direction Y. Figures 17 to 19 As shown, the connecting portion 6 has a flexible portion 6E (here, one) that is more easily bent than other portions from the loading portion 4 to the pressing portion 5, thereby enabling the height from the loading portion 4 to the pressing portion 5 to vary. By bending the flexible portion 6E when the temporary assembly is formed, the position of the pressing portion 5 can be changed in the height direction Z at one end side (YA) in the transverse direction Y. Specifically, the connecting portion 6 is formed into a U-shape or V-shape (here, a U-shape) that extends outward from the loading portion 4 in the transverse direction Y and is connected to the pressing portion 5 in a manner that folds back at its front end. The flexible portion 6E is provided at this folded portion (specifically, at its vertex) as a flexible portion related to the height change at one end of the pressing portion 5 in the transverse direction Y. On the other hand, as a flexible portion unrelated to the above-mentioned height change, the connecting portion 6 has a flexible portion 6F that is more easily bent than the flexible portion 6E at the connection portion with the pressing portion 5. The flexible portion 6F functions as a rotation axis that can rotate the pressing portion 5 around itself.

[0116] like Figures 17 to 19 As shown, the assembly portion 7 includes a pressing portion side locking portion 75 provided on the pressing portion 5 at the other end side (YB) in the transverse width direction Y and a loading portion side locking portion 74 provided on the loading portion 4. These locking portions 74 and 75 are arranged opposite to each other in the height direction Z from the loading surface 4p, and can form Figure 18 When the pressing portion 5 and the placing portion 4 are separated by a predetermined distance d in the height direction Z at the other end side (YB), the locking portions 74 and 75 in the temporary assembly state lock with each other to prevent the pressing portion 5 from being separated from the placing portion 4. On the other hand, when the pressing portion 5 and the placing portion 4 are within the predetermined distance d in the height direction Z at the other end side (YB), the locking portions 74 and 75 in the temporary assembly state face each other with a gap therebetween, so that the position of the pressing portion 5 at the other end side (YB) can be changed in the height direction Z.

[0117] Thus, in the second embodiment, both the connecting portion 6 and the assembly portion 7 function as a height-changing unit capable of changing the height from the placement surface 4p to the pressing portion 5. That is, the heights of the placement portion 4 and the pressing portion 5 can be changed at both the one end side (YA) and the other end side (YB) in the transverse direction Y.

[0118] use Figures 17 to 21 illustrate Figure 15 The formation order of the wire harness bundling structure 1C.

[0119] First, if Figure 17 As shown, the wire harness W having a circular cross section is placed on the placement surface 4 p of the placement portion 4 .

[0120] Next, if Figure 18 and Figure 19 As shown, the pressing portion 5 is tilted and rotated, primarily to deform the flexure 6F, pressing the wire harness W on the placement surface 4p against the placement surface 4p. As a result, the wire harness W, which has a circular cross-section, is sandwiched between the pressing portion 5 and the placement portion 4, spreading out in the transverse direction Y on the placement surface 4p, resulting in a reduced height (flattened state). The height of the wire harness W, which originally had a circular cross-section, is reduced to less than half.

[0121] At this time, the pressing portion side locking portion 75 is wound around the lower side of the placing portion side locking portion 74 to be in a locked state or an opposing state, thereby achieving a temporary assembled state in which the placing portion 4 and the pressing portion 5 are assembled. As a result, the wire harness W is annularly surrounded in the above-mentioned low-height state, and is thus held between the placing portion 4 and the pressing portion 5 so as not to fall out.

[0122] Furthermore, when the pressing portion 5 is tilted and rotated as described above, the flexible portion 6F, which is most easily flexible in the connecting portion 6, bends first. When the above-described locked state is established from this position, the flexible portion 6E and other parts of the connecting portion 6 can also be bent as needed. This allows the pressing portion-side locking portion 75 to move deeper toward the other end (YB) in the transverse direction Y, allowing the pressing portion-side locking portion 75 to bend around to the bottom of the placement portion-side locking portion 74.

[0123] exist Figure 18 In the case of the temporary assembly state, since the diameter of the wire harness W is relatively small, the biting portion 51V does not bite deeply into the wire harness W, and the pressing surface 50p does not contact the wire harness W. On the other hand, the locking portions 74 and 75 are in a mutually locked state. By intentionally applying an external force to press the pressing portion 5 downward in this state, as shown in FIG. Figure 20As shown, the biting portion 51V bites deeply into the wire harness W, and the pressing surface 50p can be brought into contact with the wire harness W. At this time, at one end side (YA) in the transverse direction Y, the flexible portion 6E is bent, and the height from the placement portion 4 to the pressing portion 5 is lowered. At the other end side (YB), the locking portions 74 and 75 are separated and brought into a state of facing each other with a gap therebetween.

[0124] In this way, in the temporary assembly state, the height from the loading portion 4 (loading surface 4p) to the pressing portion 5 can be changed on both sides of one end side (YA) and the other end side (YB) in the transverse width direction Y by bending the connecting portion 6 (flexure portion 6E). Therefore, in order to prohibit this height change, the loading portion 4 and the opposing extension portions 51, 52 are strongly bundled together with the wiring harness W by the bundling component 10 between the opposing parts of the paired pressing main body portions 50. By this bundling, the height change between the loading portion 4 and the pressing portion 5 is prohibited in a state where the wiring harness W is lowered, and the wiring harness W is maintained in close contact with the loading portion 4 and the pressing portion 5. By this bundling, a Figure 15 The bundled structure 1C of the wire harness is shown.

[0125] In addition, Figure 15 In the bundled structure 1C of the wire harness shown, Figure 21 As shown, the outer surface 51s of the opposing extension portion 51 is located on a continuous surface (here, the same plane F) that is smoothly continuous from the pressing surface 50p of the pressing main body portion 50, 50, so the above-mentioned bundling component 10 can bond the outer surface 51s of the opposing extension portion and the outer surface of the wire harness W pressed by the pressing surface 50p in a straight line without steps.

[0126] In addition, the wiring harness W ratio Figure 17 When the wire harness shown is thicker, in the provisional assembly state, the biting portion 51V may bite deeply into the wire harness W, the pressing surface 50p may contact the wire harness W, and the locking portions 74 and 75 may always be locked to each other.

[0127] The figures illustrating the above embodiments are schematic to some extent, and in particular, the number of wires within the wire harness W and their arrangement and layout are not necessarily accurately depicted. For example, in the cross-section of each wire harness W, when bundled with the bundling member 10, some wires within the wire harness W may be inserted inside the U-shaped or V-shaped connecting portion 6.
