Description

[Technical field]

[0001] The present invention relates to a fixing band and a flat band clamp for attaching a wire harness to be routed in a vehicle, for example, to a vehicle body. [Background technology]

[0002] For example, as a tool for wiring a wire harness in a vehicle, as disclosed in Patent Document 1, a band clamp consisting of a harness holding portion that holds the wire harness and an insertion and fixing portion that is attached to a predetermined mounting location on the vehicle, or a fixing band such as a cable tie that bundles the harness between clamps attached to predetermined locations on the vehicle are used.

[0003] A wire harness bound by the band clamp or fixing band as described above is bound to have a circular cross section by tightening the band. In today's vehicles, the number of cables has increased and the diameter of the cables has become larger due to the increase in electrical equipment, so the cross-sectional shape of the wire harnesses bundled with band clamps or fixing bands has become larger. On the other hand, the space required for routing the wire harness among the numerous devices arranged therein is becoming narrower, making it more difficult to route the wire harness along a desired path. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-150840 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned problems, the present invention has an object to provide a fixing band and a flat band clamp that can route a long body bundle even in a route with a narrow routing space. [Means for solving the problem]

[0006] The present invention relates to a fixing band that has a band portion that wraps a plurality of elongated bodies together and a buckle portion that restricts movement of the band portion in a loosening direction, and that wraps and secures a plurality of the elongated bodies together, the fixing band having a first restricting portion that extends in a first intersecting direction that intersects with the longitudinal direction of the elongated bodies, and a second restricting portion that intersects with the longitudinal direction and extends in a second intersecting direction that intersects with the first intersecting direction relative to the first restricting portion, the first restricting portion being configured by the buckle portion, or being disposed closer to the buckle portion than the second restricting portion. The second restricting portion is provided with a node portion that is deformable toward the elongated body in the second intersecting direction. It is characterized by being a fixed band.

[0007] The long body refers to a long object such as a coated electric wire, a wire harness made up of coated electric wires, or an optical fiber that is arranged to connect devices together. The buckle portion may be configured as the first restricting body, or may be configured separately from the first restricting body.

[0008] According to the present invention, a long body bundle can be routed even in a route having a narrow routing space. In detail, when the long bodies are wound and fixed with the band part, two directions in the cross section of the long body bundle can be restricted by a first restricting part extending in a first intersecting direction intersecting with the longitudinal direction and constituted by the buckle part or disposed closer to the buckle part than the second restricting part, and a second restricting part extending in a second intersecting direction intersecting with the first intersecting direction relative to the first restricting part. Therefore, the long body bundle can be made lower in height and / or narrower in width than when bundled into a circular cross section, and can be routed even in a route with a narrow routing space.

[0009] The second restricting portion is provided with a node portion that is deformable toward the elongated body in the second intersecting direction. This allows the device to conform to the cross-sectional shape of the long body bundle while holding the long body bundle, so that the long body bundle can be held firmly regardless of the cross-sectional diameter of the long body bundle.

[0010] As an aspect of the invention, the length of the first regulating portion in the extension direction may be longer than the length of the second regulating portion in the extension direction, and may be formed to be longer than the cross-sectional diameter of a bundle of elongated bodies formed by bundling multiple elongated bodies without any bias.

[0011] According to this invention, the cross-sectional shape of the long body bundle expands in the first intersecting direction, but can be made low-profile in the second intersecting direction. In other words, the long body bundle can be held in a wide, flat shape in the first intersecting direction, and the long body bundle can be arranged in a low-height arrangement space with the second intersecting direction facing the height direction.

[0012] In another aspect of the present invention, the length of the second regulating portion in the extension direction may be longer than the length of the first regulating portion in the extension direction, and may be longer than the cross-sectional diameter of a bundle of elongated bodies formed by bundling multiple elongated bodies without any bias.

[0013] According to this invention, although the cross-sectional shape of the long body bundle expands in the second intersecting direction, it can be made low-profile in the first intersecting direction. In other words, the long body bundle can be held in a wide, flat shape in the second intersecting direction, and the long body bundle can be arranged so that the first intersecting direction faces the width direction even in a narrow arrangement space.

[0014] As a further aspect of the present invention, the second restricting portion may be configured to be movable in the second intersecting direction relative to the first restricting portion. According to this invention, even if the cross-sectional shape of the long body bundle is small relative to the regulated space regulated by the first regulating portion and the second regulating portion, for example because the number of long bodies to be bundled is small or the cross-sectional diameter is thin, the second regulating portion can move toward the second intersecting direction relative to the first regulating portion and firmly hold the long bodies while being regulated in the second intersecting direction by the second regulating portion.

[0015] As a further aspect of the invention, the first restricting portion and the second restricting portion may be provided with a connecting portion that movably connects the second restricting portion to the first restricting portion in the second intersecting direction. According to this invention, the first and second restricting portions are movable in a connected state, so that the long body bundle can be reliably restricted in the first intersecting direction and the second intersecting direction.

[0016] In another aspect of the present invention, an opposing regulating portion may be provided that is arranged at a position opposite the first regulating portion in the band portion in a wound state, extends in a third intersecting direction that intersects the longitudinal direction, and faces the first regulating portion.

[0017] The third intersecting direction may be the same as the first intersecting direction, or may be the same as the first intersecting direction but at a different angle. According to this invention, since the elongate body restricted by the second restricting portion can be further restricted by the opposing restricting portion, the cross-sectional shape of the elongate body bundle can be restricted more reliably.

[0018] In another aspect of the present invention, a third regulating portion extending in the second intersecting direction may be provided at a position opposite the second regulating portion across the first regulating portion, and the third regulating portion may be formed shorter than the second regulating portion.

[0019] The second restriction portion and the third restriction portion may extend in parallel, or may extend in the same direction but at different angles. According to this invention, the long body bundle can be more reliably restricted in the second intersecting direction by both the second restricting portion and the third restricting portion provided on both sides of the first restricting portion.

[0020] The present invention is also characterized in that it is a band clamp comprising the above-mentioned fixing band and an insertion and fixing portion that is provided on the buckle portion and is inserted into a mounting hole provided at a mounting location for fixing. According to this invention, the insertion and fixing portion can be inserted into the attachment hole and fixed to the attachment location in a state in which the cross-sectional shape of the long body bundle is restricted in the first intersecting direction and the second intersecting direction.

[0021] As a further aspect of the present invention, the insertion fixing portion may be integrally formed with the buckle portion. According to this invention, the insertion and fixing portion which is integrally formed with the buckle portion can be easily inserted into the mounting hole and fixed to the mounting location.

[0022] As a further aspect of the present invention, the insertion fixing portion may be configured to be detachable from the buckle portion. According to this invention, by attaching an insertion and fixing part that corresponds to the mounting hole, even if the mounting hole is of a different type, the appropriate insertion and fixing part can be inserted into the mounting hole and easily fixed to the mounting location. In addition, the number of parts can be reduced compared to when a band clamp having an insertion and fixing part suitable for each different type of mounting hole is prepared, and versatility is improved by attaching multiple types of insertion and fixing parts.

[0023] The present invention also provides a fixing band which has a band portion which wraps around multiple long bodies and a buckle portion which regulates movement of the band portion in the loosening direction, and which wraps and fixes multiple long bodies together, and which is characterized in that it has a regulating portion which extends in a cross direction which intersects with the longitudinal direction of the long bodies, and the length of the regulating portion which extends in the cross direction is longer than the cross-sectional diameter of the bundle of long bodies which is formed by bundling multiple long bodies together without bias.

[0024] According to the present invention, the cross-sectional shape of the long body bundle can be made compact in both the longitudinal direction and the transverse direction compared to the case where the long body bundle is bundled in a circular shape. Therefore, by orienting the compact bundled direction in a narrow direction, the wiring can be performed even in a narrow wiring space. Effect of the Invention

[0025] According to the present invention, it is possible to provide a fixing band and a flat band clamp that can route a long body bundle even in a route having a narrow routing space. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] An embodiment of the present invention will now be described with reference to the drawings. First, the outline of the flat band clamp 1 will be briefly described with reference to FIGS.

[0028] FIG. 1 shows a schematic oblique view of a flat band clamp 1 holding a wire harness 100, FIG. 2 shows a front view of the flat band clamp 1 holding a wire harness 100, and FIG. 3 shows an explanatory diagram of the flat band clamp 1. Specifically, FIG. 3(a) shows a vertical cross-sectional view of the flat band clamp 1, and FIG. 3(b) shows a view taken along the line AA in FIG. 3(a).

[0029] The longitudinal direction of the wire harness 100 is defined as the longitudinal direction L, the direction perpendicular to the longitudinal direction L and in which the anchor portion 31 described later is inserted into the mounting hole 201 is defined as the height direction H, and the direction perpendicular to the longitudinal direction L and the height direction H is defined as the width direction W. Moreover, one side in the width direction W (the left side in FIG. 2) is defined as a first width direction Wf, and the other side (the right side in FIG. 2) is defined as a second width direction Ws.

[0030] The flat band clamp 1 is a jig that attaches and fixes the wire harness 100 to a predetermined position (attachment hole 201) in the vehicle 200. The wire harness 100 is configured by bundling together a plurality of long electric wires 101, one end of which is connected to an electronic device, a battery, or the like (not shown).

[0031] The flat band clamp 1 is composed of a fixing band 2 that holds the wire harness 100 and an insertion fixing portion 3 that is attached to a mounting hole 201 that is a predetermined mounting location in a vehicle 200.

[0032] The fixing band 2 has a band part 21 that winds a wire harness 100 in which a plurality of long electric wires 101 are bundled together, and a buckle part 22 that restricts movement of the band part 21 in the loosening direction, and winds the plurality of electric wires 101 together and fixes them as the wire harness 100.

[0033] More specifically, the fixing band 2 is composed of a buckle portion 22 that extends in a width direction W perpendicular to the longitudinal direction L of the wire harness 100 and functions as a first regulating body, a side regulating body 24 that is pivotally connected by a hinge 23 provided in the first width direction Wf of the buckle portion 22 and functions as a second regulating body, and a band portion 21 extending from the first width direction Wf of the side regulating body 24.

[0034] The buckle portion 22, which restricts the movement of the band portion 21 in the loosening direction and also functions as a first restricting body, is rectangular in plan view, longer in the width direction W than in the longitudinal direction L, as shown in Fig. 3(b), and is a plate-like body that is thicker than the thickness of the band portion 21, and has an insertion hole 221 therein for inserting the band portion 21. Although not shown, the insertion hole 221 is provided with a slip-out prevention piece that prevents the inserted band portion 21 from slipping out.

[0035] 2, the length of the buckle portion 22 in the width direction W is longer than an imaginary cross-sectional diameter D of an imaginary circle C of the wire harness 100 in which the electric wires 101 are bundled without being biased. In this embodiment, the buckle portion 22 is formed with a length in the width direction W of about 1.5 of the imaginary cross-sectional diameter D.

[0036] The side regulating body 24, which functions as the second regulating body, is pivotally connected to the buckle portion 22 by the hinge 23, and is therefore configured to be switchable between an unfolded state in which it extends in the width direction W relative to the buckle portion 22, as shown in Figure 3(a), and a folded state pivoted by the hinge 23, as shown in Figure 2.

[0037] The side restriction body 24 is formed so that the length in the width direction W in the unfolded state is shorter than that of the buckle portion 22 and shorter than the above-mentioned imaginary cross-sectional diameter D. In this embodiment, the side restriction body 24 is formed so that the length in the width direction W is approximately 1 / 2 of the imaginary cross-sectional diameter D. In the above-described folded state, the side restriction body 24 folded with respect to the buckle portion 22 extending in a width direction W perpendicular to the longitudinal direction L faces a height direction H intersecting the longitudinal direction L and the width direction W.

[0038] The band portion 21 is a strip-shaped body having a width approximately half the length of the buckle portion 22 in the longitudinal direction L, has flexibility, and is provided so as to protrude from the upper surface of one end side of the side restriction body 24. The band portion 21 wound around the outside of the wire harness 100 is formed to have a length longer than the outer periphery of the wire harness 100. Further, the band portion 21 is formed with a locking groove in which a slip-out prevention piece (not shown) provided in the insertion hole 221 is locked when the band portion 21 is inserted into the insertion hole 221.

[0039] The insertion and fixing portion 3 is for attaching the fixing band 2 to an attachment hole 201 of the vehicle 200, and is provided on a rear surface 22a of the buckle portion 22. The insertion fixing portion 3 includes an anchor portion 31 and a slide fixing portion 32 that fixes the anchor portion 31 to the back surface 22 a of the buckle portion 22 .

[0040] The anchor portion 31 is provided with, for example, an insertion shaft portion that is inserted into the mounting hole 201, and a locking arm portion that spreads out in the width direction W from the insertion shaft portion and locks onto the peripheral portion of the mounting hole 201, and by inserting the insertion shaft portion into the mounting hole 201, the locking arm portion can lock onto and be fixed to the peripheral portion of the mounting hole 201. Note that the structure of the anchor portion 31 is not limited to the above-mentioned structure, and may be, for example, a clip-like structure.

[0041] The slide fixing portion 32 is for fixing the anchor portion 31 to the buckle portion 22 , and is provided on the back surface 22 a of the buckle portion 22 . The slide fixing portion 32 provided on the back surface 22a of the buckle portion 22 can fix the anchor portion 31 by sliding the anchor portion 31 in the width direction W.

[0042] In the flat band clamp 1 configured in this manner, the anchor portion 31 is slid in the width direction W onto the slide fixing portion 32 provided on the back surface 22a of the buckle portion 22, and the anchor portion 31 is fixed to the back surface 22a of the buckle portion 22 to form the insertion fixing portion 3. At this time, the anchor portion 31 is attached in accordance with the size and mounting structure of the mounting hole 201 of the vehicle 200 to which the anchor portion 31 is to be attached.

[0043] Then, the wire harness 100 is placed on the upper surface 22b of the buckle portion 22 in the unfolded state shown in Fig. 3. At this time, the multiple electric wires 101 constituting the wire harness 100 are separate and independent. In order to bundle up the electric wires 101 arranged on the upper surface 22b of the buckle portion 22 and wind them with the band portion 21, the side restriction body 24 is bent with respect to the buckle portion 22 at the hinge 23, and the band portion 21 is wound around the outer periphery of the electric wires 101. Then, the band portion 21 is inserted into the insertion hole 221 from the second width direction Ws of the buckle portion 22 and tightened, whereby the wire harness 100 composed of the electric wires 101 can be flattened by the fixing band 2 and held by the fixing band 2.

[0044] As described above, the insertion and fixing portion 3 of the flat band clamp 1 holding the wire harness 100 with the fixing band 2 is inserted from the height direction H into the mounting hole 201 of the vehicle 200 to be mounted, and the flat band clamp 1 holding the wire harness 100 is fixed to the vehicle 200, thereby completing the fixing of the wire harness 100 to the vehicle 200.

[0045] The flat band clamp 1 thus configured includes a band portion 21 for winding a plurality of long electric wires 101 together, and a buckle portion 22 for restricting movement of the band portion 21 in the slack direction, and has a fixing band 2 for winding and fixing a plurality of electric wires 101 together. The fixing band 2 of the flat band clamp 1 has the buckle portion 22 extending in a width direction W intersecting with the longitudinal direction L of the electric wires 101, and a side restricting body 24 extending in a height direction H intersecting with the longitudinal direction L and intersecting with the width direction W relative to the buckle portion 22.

[0046] Therefore, the flat band clamp 1 can route the wire harness 100 even in a route where the routing space is narrowed. In detail, when the electric wires 101 are wound and fixed by the band portion 21, the two directions of the width direction W and the height direction H in the cross section of the wire harness 100 can be restricted by the buckle portion 22 extending in the width direction W intersecting with the longitudinal direction L and the side restricting body 24 extending in the height direction H intersecting with the width direction W with respect to the buckle portion 22. Therefore, the height can be reduced compared to the case where the wire harness 100 is bundled into a circular cross section, that is, the wire harness 100 can be held in a flat shape wide in the width direction W. Therefore, the wire harness 100 can be routed even in a route with a narrow routing space.

[0047] Moreover, the flat band clamp 1 includes the above-mentioned fixing band 2 and the insertion and fixing portion 3 that is provided on the buckle portion 22 and is inserted into and fixed to the mounting hole 201 provided in the vehicle 200, so that the insertion and fixing portion 3 can be inserted into the mounting hole 201 and fixed to the vehicle 200 while restricting the cross-sectional shape of the wire harness 100 in the width direction W and height direction H. Therefore, in the state of being fixed to the vehicle 200, the height and width of the wire harness 100 can be restricted by the buckle portion 22 and the side restriction body 24.

[0048] In addition, the length in the width direction W of the buckle portion 22 is longer than the length in the height direction H of the side regulating body 24, and is also longer than the imaginary cross-sectional diameter D of the wire harness 100 in which multiple electric wires 101 are bundled together without any bias. Therefore, although the flat band clamp 1 expands in the width direction W in the cross-sectional shape of the wire harness 100, it can be made low-profile in the height direction H, so that the wire harness 100 can be routed such that the height direction H faces the height direction even in a low-height routing space.

[0049] Furthermore, since the insertion and fixing portion 3 is configured to be detachable from the buckle portion 22, by attaching an insertion and fixing portion 3 (anchor portion 31) that corresponds to the mounting hole 201, the appropriate insertion and fixing portion 3 (anchor portion 31) can be inserted into the mounting hole 201 and easily fixed to the mounting location, even if the type of mounting hole 201 is different.

[0050] In addition, the number of parts can be reduced compared to preparing a band clamp having an insertion fixing portion 3 (anchor portion 31) suitable for each different type of mounting hole 201, and versatility is improved by attaching multiple types of insertion fixing portions 3 (anchor portions 31).

[0051] In addition, the buckle portion 22 and the side regulating body 24 are provided with a hinge 23 that movably connects the side regulating body 24 to the buckle portion 22 in the height direction H, so that the buckle portion 22 and the side regulating body 24 can move in a connected state, and the wire harness 100 can be reliably regulated in the width direction W and the height direction H.

[0052] In the above-mentioned flat band clamp 1, a buckle portion 22 is provided that is longer in the width direction W than the imaginary cross-sectional diameter D of the wire harness 100 in which multiple electric wires 101 are bundled together in a circular cross-section, and a side regulating body 24 that is shorter than the buckle portion 22 is pivotally connected via a hinge 23. However, as in the flat band clamp 1a, which is a modified example of the flat band clamp 1 shown in Figure 4, an insertion fixing portion 3 may be provided on the side regulating body 24 that is shorter in length than the buckle portion 22.

[0053] 4 shows a front view of the flat band clamp 1a of the modified example. In the following description of the flat band clamp 1a, the same components as those of the flat band clamp 1 described above are given the same reference numerals and the description thereof will be omitted.

[0054] In the flat band clamp 1a, a buckle portion 22 having an insertion hole 221 is pivotally connected by a hinge 23 to a side restriction body 24 provided with an insertion fixing portion 3. In this flat band clamp 1a, in the deployed state, the length of the side restriction body 24 in the width direction W is shorter than the length of the buckle portion 22 and shorter than the imaginary cross-sectional diameter D of the imaginary circle C. The buckle portion 22 extending in the height direction H in the folded state is longer than the side restriction body 24 and is longer than the diameter D of an imaginary cross section.

[0055] The flat band clamp 1a configured in this manner has the same effect as the flat band clamp 1 described above, and the length of the side regulating body 24 is shorter than the length of the buckle portion 22 and shorter than the imaginary cross-sectional diameter D of the wire harness 100 in which the multiple electric wires 101 are bundled without being biased, so that the cross-sectional shape of the wire harness 100 expands in the height direction H but can be made low in the width direction W. That is, the flat band clamp 1a can hold the wire harness 100 in a flat shape that is wide in the height direction H. Therefore, even in a narrow wiring space, the wire harness 100 can be wired with the width direction W facing the width direction.

[0056] Second embodiment Next, a flat band clamp 1b according to a second embodiment shown in FIG. 5 will be described. 5 shows a front view of the flat band clamp 1b of the second embodiment. In the following description of the flat band clamp 1b, the same components as those of the flat band clamp 1 described above are given the same reference numerals and the description thereof will be omitted.

[0057] The flat band clamp 1b of the second embodiment includes an opposing regulating body 25 in addition to the configuration of the flat band clamp 1 described above. In detail, in contrast to the above-mentioned flat band clamp 1 having a band portion 21, a buckle portion 22 and a side regulating body 24, the flat band clamp 1b of the second embodiment has an opposing regulating body 25 that extends in the width direction W above the wire harness 100 when the wire harness 100 is held.

[0058] The opposing restriction body 25 is formed to be longer than the side restriction body 24 and shorter than the buckle portion 22. The opposing restriction body 25 is formed to be longer than an imaginary cross-sectional diameter D of the imaginary circle C. In the above-mentioned flat band clamp 1, the side regulating body 24 is pivotally connected to the buckle portion 22 by a hinge 23 provided in the first width direction Wf, but in the flat band clamp 1b, the band portion 21 extends from the first width direction Wf of the buckle portion 22, and the side regulating body 24 and the opposing regulating body 25 are inserted through the band portion 21 and fixed to the band portion 21 by adhesion, welding, or the like. That is, in the flat band clamp 1b, the side regulating body 24 and the opposing regulating body 25 are movably connected by the band portion 21 extending from the first width direction Wf of the buckle portion 22.

[0059] In addition, whereas the flat band clamp 1 is equipped with an insertion fixing portion 3 to which the anchor portion 31 can be attached and detached by a slide fixing portion 32 provided on the back surface 22a of the buckle portion 22, in the flat band clamp 1b, the anchor portion 31 is provided directly on the back surface 22a of the buckle portion 22 to form the insertion fixing portion 3.

[0060] In the flat band clamp 1b configured in this manner, similarly to the flat band clamp 1 described above, multiple electric wires 101 constituting the wire harness 100 are arranged on the upper surface 22b of the buckle portion 22, and the band portion 21 to which the side regulating body 24 and the opposing regulating body 25 are fixed is wound around the outside of the multiple electric wires 101 bundled together, and inserted from the end of the insertion hole 221 in the second width direction Ws of the buckle portion 22 and fixed.

[0061] As described above, the flat band clamp 1b is positioned at a position opposite the buckle portion 22 in the band portion 21 in the wound state, extends in a width direction W intersecting the longitudinal direction L, and is provided with an opposing regulating body 25 opposite the buckle portion 22.

[0062] Therefore, in addition to the effects achieved by the flat band clamp 1 described above, the flat band clamp 1b can further regulate the electric wires 101, which are regulated by the side regulating body 24, with the opposing regulating body 25, so that the cross-sectional shape of the wire harness 100 can be more reliably regulated. In detail, the flat band clamp 1b can regulate the height and width of the wire harness 100 with the buckle portion 22 and the side regulating body 24 in a state fixed to the vehicle 200, and furthermore, the opposing regulating body 25 can more reliably regulate the height of the wire harness 100 held in a flat shape.

[0063] Furthermore, since the side regulating body 24 can move in the height direction H relative to the buckle portion 22, even if the cross-sectional shape of the wire harness 100 is small relative to the regulated space regulated by the buckle portion 22 and the side regulating body 24, for example, because the number of wires 101 to be bundled is small or the imaginary cross-sectional diameter D is narrow, the side regulating body 24 can move in the height direction H relative to the buckle portion 22 and firmly hold the wire harness 100 while being regulated in the height direction H by the side regulating body 24.

[0064] Furthermore, since the insertion and fixing portion 3 is integrally formed with the buckle portion 22, the insertion and fixing portion 3 integrally formed with the buckle portion 22 can be inserted into the mounting hole 201 and easily fixed to the mounting location. In the flat band clamp 1b, the opposing regulating body 25 and the buckle portion 22 may be in the same direction as described above, or may be in the same direction but at different angles.

[0065] Third embodiment Next, a flat band clamp 1c according to a third embodiment shown in FIG. 6 will be described. 6 shows a front view of the flat band clamp 1c of the third embodiment. In the following description of the flat band clamp 1c, the same components as those of the flat band clamp 1 described above are denoted by the same reference numerals and the description thereof will be omitted.

[0066] A flat band clamp 1c of the third embodiment includes, in addition to the configuration of the flat band clamp 1 described above, a side restriction body 26 also in the second width direction Ws. More specifically, whereas the above-described flat band clamp 1 includes a band portion 21, a buckle portion 22, and a side restriction body 24, a flat band clamp 1c of the third embodiment includes a side restriction body 26 extending in the height direction H.

[0067] The side restriction body 26 is formed shorter than the imaginary cross-sectional diameter D of the buckle portion 22, the side restriction body 24, and the imaginary circle C, and includes an insertion hole 261 through which the band portion 21 passes. In the above-mentioned flat band clamp 1, the side regulating body 24 is pivotally connected to the buckle portion 22 by a hinge 23 provided in the first width direction Wf, but the flat band clamp 1c does not have a hinge 23, and flexible thin-walled portions 27 are provided at both ends of the buckle portion 22 in the width direction W, and the side regulating body 24 and the side regulating body 26 are movably connected to the buckle portion 22 by the flexible thin-walled portions 27. In addition, in the flat band clamp 1c, similarly to the above-mentioned flat band clamp 1b, an anchor portion 31 is provided directly on the back surface 22a of the buckle portion 22 to form the insertion fixing portion 3.

[0068] In the flat band clamp 1c thus configured, similarly to the flat band clamp 1 described above, the multiple electric wires 101 constituting the wire harness 100 are arranged on the upper surface 22b of the buckle portion 22, the side restriction body 24 in the first width direction Wf is pivoted in the height direction H, and the band portion 21 to which the side restriction body 26 is fixed is wound around the outside of the multiple electric wires 101 together. Also, in the second width direction Ws, the side restriction body 26 is pivoted in the height direction H, and the band portion 21 wound around the outside of the multiple electric wires 101 is inserted into the insertion hole 261 and inserted from the end of the insertion hole 221 in the second width direction Ws of the buckle portion 22 and fixed.

[0069] In addition, the flat band clamp 1c has a flexible thin portion 27 extending in the height direction H at a position opposite the side regulation body 24 across the buckle portion 22, and the flexible thin portion 27 is formed shorter than the side regulation body 24.

[0070] Therefore, in addition to the effects achieved by the flat band clamp 1 described above, the flat band clamp 1c can more reliably regulate the wire harness 100 in the height direction H by both the side regulating bodies 24 and the flexible thin-walled portions 27 provided on both sides of the buckle portion 22.

[0071] In detail, when the flat band clamp 1c is fixed to the vehicle 200, the height and width of the wire harness 100 can be restricted by the buckle portion 22 and the side regulating body 24, and further, the width of the wire harness 100 held in a flat shape can be more reliably restricted by the side regulating body 26.

[0072] In addition, the buckle portion 22 and the side regulating body 24 are provided with a flexible thin-walled portion 27 that movably connects the side regulating body 24 to the buckle portion 22 in the height direction H, and therefore the buckle portion 22 and the side regulating body 24 can move in a connected state, thereby reliably regulating the wire harness 100 in the width direction W and the height direction H.

[0073] The side restriction bodies 24 and 26 may extend parallel to each other in the height direction H, or may extend at different angles. In addition, the buckle portion 22 may be constructed of a simple plate-like body, and the insertion hole 261 of the side regulating body 26 may be provided with an anti-slip piece (not shown) that prevents the inserted band portion 21 from slipping out, and the buckle portion may be formed by the side regulating body 26.

[0074] (Fourth embodiment) Next, a flat band clamp 1d according to a fourth embodiment shown in FIG. 7 will be described. 7 shows a front view of the flat band clamp 1d of the fourth embodiment. In the following description of the flat band clamp 1d, the same components as those of the flat band clamp 1 described above are denoted by the same reference numerals and the description thereof will be omitted.

[0075] The flat band clamp 1d of the fourth embodiment is configured with a flexible side restriction body 24X in which a hinge 28 is provided near the center of the side restriction body 24 in the flat band clamp 1 described above. More specifically, the flexible side restriction body 24X is configured to be a center-folding type in which restriction pieces 241 each having a length approximately half that of the side restriction body 24 in the flat band clamp 1 are connected to each other by a hinge 28.

[0076] In the flat band clamp 1d configured in this manner, similarly to the flat band clamp 1, the wire harness 100 is placed on the upper surface 22b of the buckle portion 22 in the unfolded state, and is wound around the band portion 21. The flexible side regulating body 24X is bent at the hinge 23 with respect to the buckle portion 22, and the band portion 21 is wound around the outer periphery of the plurality of wires. At this time, the flexible side regulating body 24X is bent in the middle at the hinge 28, and the wires are bundled and arranged along the side of the electric wires 101. Then, the band portion 21 is inserted into the insertion hole 221 from the other end side of the buckle portion 22. Then, by tightening the band portion 21, the wire harness 100 composed of the plurality of electric wires 101 can be held by the fixing band 2.

[0077] Then, the insertion and fixing portion 3 of the flat band clamp 1 holding the fixing band 2 and the wire harness 100 is inserted from the height direction H into the mounting hole 201 of the vehicle 200 to be mounted, and the flat band clamp 1 holding the wire harness 100 is fixed to the vehicle 200, thereby completing the fixing of the wire harness 100 to the vehicle 200.

[0078] The flat band clamp 1d has a hinge 28 on the flexible side regulating body 24X that can deform toward the electric wire 101 in the height direction H. Therefore, in addition to the effects achieved by the flat band clamp 1 described above, the flat band clamp 1d can conform to the cross-sectional shape of the wire harness 100 while holding the wire harness 100, thereby enabling the wire harness 100 to be held firmly regardless of its size.

[0079] In other words, like the flat band clamp 1, the flat band clamp 1d can hold the wire harness 100 in a wide flat shape in the width direction W, and when fixed to the vehicle 200, the height and width of the wire harness 100 can be regulated by the buckle portion 22 and the flexible side regulating body 24X.

[0080] In addition, in the flexible side regulating body 24X, the regulating pieces 241 may be connected to each other by the flexible thin-walled portion 27 so as to be able to fold in half, or the band portion 21 may be inserted into the regulating pieces 241 and fixed to the band portion 21 through which the regulating pieces 241 are inserted, so that the regulating pieces 241 are able to fold in half.

[0081] Fifth embodiment Next, a flat band clamp 1e according to a fifth embodiment shown in FIG. 8 will be described. 8 shows a front view of the flat band clamp 1e of the fifth embodiment. In the following description of the flat band clamp 1e, the same components as those of the flat band clamp 1 described above are denoted by the same reference numerals and the description thereof will be omitted.

[0082] A flat band clamp 1e of the fifth embodiment does not include the side restriction body 24 of the flat band clamp 1 described above, and is composed of a fixing band 2 composed of a band portion 21 and a buckle portion 22, and an insertion fixing portion 3. More specifically, the band portion 21 extends from a first width direction Wf of the buckle portion 22 which is long in the width direction W.

[0083] In the flat band clamp 1e configured in this manner, similarly to the flat band clamp 1, the wire harness 100 is placed on the upper surface 22b of the buckle portion 22 and wound with the band portion 21. Then, the band portion 21 is inserted into the insertion hole 221 from the second width direction Ws of the buckle portion 22. Then, by tightening the band portion 21, the wire harness 100 composed of a plurality of electric wires 101 can be flattened by the fixing band 2 and held by the fixing band 2.

[0084] Then, the insertion and fixing portion 3 of the flat band clamp 1 holding the wire harness 100 with the fixing band 2 is inserted from the height direction H into the mounting hole 201 of the vehicle 200 to be mounted, and the flat band clamp 1 holding the wire harness 100 is fixed to the vehicle 200, thereby completing the fixing of the wire harness 100 to the vehicle 200.

[0085] The flat band clamp 1e, like the flat band clamp 1 described above, can flatten the wire harness 100 and hold it firmly. In other words, like the flat band clamp 1, the flat band clamp 1e can hold the wire harness 100 in a wide flat shape in the width direction W, and when fixed to the vehicle 200, the width of the wire harness 100 can be regulated by the buckle portion 22.

[0086] In the configuration of the present invention and the above-mentioned embodiment, the long body corresponds to the electric wire 101, Similarly, The band section corresponds to band section 21. The buckle portion corresponds to the buckle portion 22, The fixed band corresponds to the fixed band 2. The longitudinal direction corresponds to the longitudinal direction L, The first transverse direction corresponds to the width direction W, The first restricting portion corresponds to the buckle portion 22, The second intersecting direction corresponds to the height direction H, The second restricting portion corresponds to the side restricting body 24, The long bundle corresponds to wire harness 100, The cross-sectional diameter corresponds to the imaginary cross-sectional diameter D, The connecting portion corresponds to the hinge 23 and the flexible thin portion 27. The joint corresponds to the hinge 28, The third transverse direction corresponds to the width direction W; The opposing regulating portion corresponds to the opposing regulating body 25, The third restricting portion corresponds to the side restricting body 26, The insertion and fixing part corresponds to the insertion and fixing part 3, The flat band clamps correspond to the flat band clamps 1, 1a, 1b, 1c, 1d, and 1e, The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0087] For example, in the above description, the flat band clamp 1 is constituted by the fixing band 2 and the insertion fixing portion 3, but as shown in FIG. 9, it may be constituted by only the fixing band 2 without the insertion fixing portion 3. The fixing band 2 not including the insertion fixing portion 3 can make the height direction H of the wire harness 100 held in a flat shape more compact than when bundled in a circular shape, similar to the flat band clamp 1. Therefore, by orienting the compact bundled direction in a narrow direction, the wire harness can be wired even in a narrow wiring space.

[0088] Specifically, for example, by using the above-mentioned fixing band 2 to hold the space between the flat band clamps 1 of the wire harness 100 held at intervals by the flat band clamps 1 in the vehicle 200, the flat shape of the entire wire harness 100 can be maintained and the width and height of the wire harness 100 can be regulated by the buckle portion 22 and the side regulating body 24, allowing the wire harness 100 to be routed in a narrow routing space.

[0089] As a modified example of the fixing band 2, similar to the flat band clamp 1e, a fixing band 2a not including the side restriction body 24 may be used as shown in FIG. Like the fixing band 2, the fixing band 2a can also make the height direction H of the wire harness 100 held in a flat shape more compact than when bundled in a circular shape. Therefore, by orienting the compact bundling direction in a narrow direction, the wire harness can be wired even in a narrow wiring space.

[0090] Specifically, for example, by holding the flat band clamps 1 of the wire harness 100 held at intervals by the flat band clamps 1 in the vehicle 200 with the above-mentioned fixing band 2a, the flat shape of the entire wire harness 100 can be maintained and the width of the wire harness 100 can be restricted by the buckle portion 22, allowing the wire harness 100 to be routed in a narrow routing space.

[0091] In the above description, the wire harness 100 bundling the electric wires 101 is held by the fixing band 2, but the fixing band 2 can hold a long object such as an optical fiber that is routed to connect devices together. In the above description, a buckle portion 22 is provided that functions as a first regulating portion that regulates the width of the wire harness 100. However, the buckle portion having an anti-pullout piece that prevents the inserted band portion 21 from slipping out and a plate-like body that functions as the first regulating portion may be constructed separately, and the plate-like body that functions as the first regulating portion may be positioned on the buckle portion side relative to the side regulating body 24.

[0092] Furthermore, the hinge 23 and the flexible thin portion 27 in the above description may be interchanged, or the band portion 21 may be inserted and fixed in place of the hinge 23 and the flexible thin portion 27 to allow movement. Also, the insertion and fixing portion 3 in which the anchor portion 31 is detachably attached to the buckle portion 22 by the slide fixing portion 32 may be interchanged with the insertion and fixing portion 3 in which the anchor portion 31 is fixed to the buckle portion 22.
