Description

[Technical Field]

[0001] The present invention relates to a band clamp for fixing a flat electric wire to, for example, a vehicle body panel, and a flat electric wire with a band clamp. [Background technology]

[0002] A long wire harness electrically connecting electrical devices mounted on a vehicle is routed in a two-dimensional or three-dimensional complex routing path that combines straight and curved sections, and is attached to a body panel of the vehicle via a band clamp such as that disclosed in Patent Document 1.

[0003] The band clamp disclosed in Patent Document 1 will be described in detail. This band clamp can hold a wire harness by wrapping a strip-shaped band around the wire harness and inserting a tip end of the band into a buckle connected to the base end of the band and tightening it. Then, the fixing member (anchor) of the band clamp holding the wire harness is inserted into a through-hole in the vehicle body panel to fix the wire harness to the vehicle body panel.

[0004] In recent years, the amount of electric current required by vehicles has increased with the increase in the number of electrical devices installed in vehicles, and the diameter of the wires in the wire harnesses has also increased accordingly. However, by using flat wires in the wire harness, it is possible to prevent the wire harness from becoming too large.

[0005] However, when a flat electric wire is held by the above-mentioned band clamp, a gap occurs between the flat electric wire and the band portion, making it impossible to hold the flat electric wire firmly. Also, when the band portion is tightened to hold the flat electric wire firmly, the flat electric wire bends in the thickness direction along the arc-shaped band portion. This poses a problem in that the advantages of a flat electric wire cannot be obtained. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-282352 Summary of the Invention [Problem to be solved by the invention]

[0007] In view of the above-mentioned problems, an object of the present invention is to provide a band clamp and a flat electric wire with a band clamp that can firmly hold a flat electric wire while maintaining the shape of the flat electric wire. [Means for solving the problem]

[0008] The present invention provides a vehicle body fixing device that includes a vehicle body fixing portion that is fixed to a vehicle body panel of a vehicle, a band portion that holds a flat electric wire along an outer surface of the flat electric wire that is laid in the vehicle, a connecting portion that connects at least a part of the band portion to the vehicle body fixing portion, and a band locking portion that locks and fixes the band portion that holds the flat electric wire, and the band locking portion is arranged on at least one side in the width direction of the flat electric wire that it holds. The band portion is provided with a locking piece, and the band locking portion is provided with an insertion hole through which the band portion is inserted and a locked portion that locks with the locking piece of the band portion inserted into the insertion hole, the band locking portion is configured as a separate body from the band portion, and the insertion holes of the band locking portion are configured to respectively insert two ends of the band portion that protrude at least on one side in the width direction. It is a band clamp.

[0009] The present invention also provides a band clamp including a flat electric wire to be routed in a vehicle, a vehicle body fixing portion that is fixed to a vehicle body panel of the vehicle, a band portion that holds the flat electric wire along an outer surface, a connecting portion that connects at least a part of the band portion to the vehicle body fixing portion, and a band locking portion that locks and fixes the band portion in a state in which the flat electric wire is held, wherein the band locking portion is arranged on at least one side in a width direction of the flat electric wire to be held. The band clamp has a locking piece provided on the band portion, and the band locking portion has an insertion hole through which the band portion is inserted and an engaged portion that locks with the locking piece of the band portion inserted into the insertion hole, the band locking portion is configured as a separate body from the band portion, and the insertion holes in the band locking portion are inserted through two ends of the band portion that protrude at least on one side in the width direction. It is a flat wire with a band clamp.

[0010] The vehicle body fixing portion includes, for example, an anchor that is inserted into an insertion hole provided in a vehicle body panel for fixing, or a stud bolt that is inserted into a bolt fixed to the vehicle body panel for fixing. The above-mentioned "at least a portion of the band portion" includes a case where the band portion is composed of one band portion connected to the connecting portion, or a case where the band portion is composed of multiple band portions at least a portion of which is connected to the connecting portion. For example, this includes a case where the band portion is composed of one band portion that is connected to the connecting portion by being inserted into the connecting portion, a case where the band portion is composed of multiple band portions connected to the connecting portion, and a case where the band portion is composed of a band portion connected to the connecting portion and a band portion that is not connected to the connecting portion.

[0011] The band locking portion may be provided integrally with or separately from the band portion, or may be provided integrally with the connecting portion. The width direction of the flat electric wire refers to the longitudinal direction in an orthogonal cross section perpendicular to the longitudinal direction of the flat electric wire. That is, the band locking portion is disposed on at least one of both outer sides in the longitudinal direction of the orthogonal cross section of the flat electric wire.

[0012] The flat electric wire may be held by the band portion so that the width direction is parallel to the vehicle body panel, or may be held by the band portion so that the width direction is perpendicular to the vehicle body panel. The above-mentioned "along the outer surface of the flat electric wire" refers to a state along at least a part of the outer surface of the flat electric wire along the width direction, i.e., it includes a case where the wire is along a surface along the short direction of the orthogonal cross section of the flat electric wire, and a case where the wire is not along the surface.

[0013] The above-mentioned "at least two ends on one side in the width direction" includes cases where both ends of one band part connected to the connecting part protrude to one side in the width direction, cases where the ends of two band parts connected to the connecting part, or cases where one band part connected to the connecting part and the ends of one band part not connected to the connecting part protrude to one side in the width direction. The band portion and the band locking portion include a configuration in which each band portion inserted into the insertion hole is locked, and a configuration in which two band portions are inserted into the insertion holes respectively, so that the two band portions are locked and fixed together with the band locking portion.

[0014] According to this invention, by fastening the band portion with the band fastening portion, the band portion can hold the flat electric wire so that it conforms to the outer surface of the flat electric wire, thereby enabling the band portion to firmly hold the flat electric wire and preventing the flat electric wire from bending in the plate thickness direction. This allows the shape of the flat electric wire to be maintained and the flat electric wire to be fixed to a predetermined location on the vehicle without applying a load to the flat electric wire. Therefore, the height of the flat electric wire in the plate thickness direction can be reduced, and the effects of the flat electric wire, such as improved heat dissipation, can be obtained. Note that maintaining the shape of the flat electric wire here means preventing bending to an extent that the effects of the flat electric wire, such as heat dissipation, can be achieved.

[0015] In addition, a locking piece is provided on the band portion, and the band locking portion is provided with an insertion hole through which the band portion is inserted and an engaged portion that locks with the locking piece on the band portion inserted into the insertion hole.

[0016] As a result, by simply pulling the band portion that is inserted through the insertion hole to at least one side in the width direction, the band locking portion can be locked and fixed to the band portion while preventing unintended loosening of the band portion from tightening around the flat electric wire, thereby efficiently holding the flat electric wire in the band portion.

[0017] Furthermore, the band locking portion is formed separately from the band portion, and the insertion holes in the band locking portion respectively pass through the two ends of the band portion protruding on at least one side in the width direction.

[0018] With this, by inserting the two end portions protruding on one side in the width direction into the insertion holes and pulling them to one side in the width direction, the flat electric wire can be reliably held by the band portion arranged in the plate thickness direction of the flat electric wire, and the band portion and the band locking portion can be locked and fixed together. Therefore, the operation of holding the flat electric wire in the band portion can be performed efficiently.

[0019] Furthermore, since the band fastening portion is separate from the band portion, the band fastening portion can be positioned at the center of the flat electric wire in the thickness direction regardless of the thickness of the flat electric wire, which makes it possible to more reliably prevent the flat electric wire from being bent due to being fastened by the band portion.

[0020] As an aspect of the present invention, the band portion may hold the flat electric wires so that the width direction is parallel to the vehicle body panel. According to this invention, the flat electric wire can be routed so that the width direction of the flat electric wire is along the vehicle body panel, and therefore the vehicle space around the routed flat electric wire can be effectively utilized.

[0021] In another aspect of the present invention, the band portion may have a bending promoting portion for promoting bending on at least the other side in the width direction. The above-mentioned "at least the other side in the width direction" includes cases where the bending-promoting portion is present on one side as well as the other side in the width direction, i.e., the side where the band locking portion is located, or cases where the bending-promoting portion is present on the entire band portion.

[0022] According to this invention, at least on the other side in the width direction, the band portion can be bent to follow the outer shape of the other side in the width direction of the flat electric wire. That is, the band portion can be aligned with a part of the surface along the short direction in the orthogonal cross section of the flat electric wire, so that it is possible to prevent a gap from being formed between the band portion and the flat electric wire, and the flat electric wire can be reliably held by the band portion.

[0023] Furthermore, when a bending-promoting portion is provided on both the other and one widthwise side, the band portion can be bent to fit the outer surface of the flat electric wire on both widthwise sides of the band portion, so that the band portion can be bent along the outer surface of the flat electric wire on both widthwise sides, thereby more reliably holding the flat electric wire with the band portion.

[0024] In another aspect of the present invention, the bending promoting portion may be configured as a groove on the outer surface of the band portion along the longitudinal direction of the flat electric wire. The bending facilitating portion may be singular or plural. When there are plural bending facilitating portions, they may be arranged at equal or unequal intervals along the longitudinal direction of the band portion, and the depth of the grooves of the bending facilitating portions may be uniform or uneven.

[0025] According to this invention, the bending-promoting portion can be formed with a simple structure. Therefore, the band portion can be bent along the outer surface of the flat electric wire with a simple structure, and the flat electric wire can be held more firmly. Furthermore, when a large number of bending-promoting portions are arranged along the longitudinal direction of the band portion, the band portion can be bent along the outer surface of the flat electric wire even for various flat electric wires with different plate thicknesses and width lengths.

[0026] As another aspect of the present invention, the locking pieces may be provided on the outer surface of the band portion that holds the flat electric wires. The outer surface of the band portion mentioned above refers to the surface opposite to the surface facing the flat electric wires when the flat electric wires are held by the band portion.

[0027] According to this invention, the band fastening portion can be more reliably fastened and fixed to the band portion. In more detail, since the band portion is bent inward in the thickness direction of the flat electric wire and inserted into the insertion hole, a reaction force acts on the band portion in the thickness direction inside the insertion hole. This reaction force ensures that the inner surface of the band locking portion in the thickness direction and the outer surface of the band portion come into contact with each other, thereby more reliably locking the locking piece and the locked portion.

[0028] In another aspect of the present invention, the band locking portion may be formed separately from the band portion, and the insertion holes in the band locking portion may each receive two ends of the band portion protruding on at least one side in the width direction.

[0029] The above-mentioned "at least two ends on one side in the width direction" includes cases where both ends of one band part connected to the connecting part protrude to one side in the width direction, cases where the ends of two band parts connected to the connecting part, or cases where one band part connected to the connecting part and the ends of one band part not connected to the connecting part protrude to one side in the width direction. The band portion and the band locking portion include a configuration in which each band portion inserted into the insertion hole is locked, and a configuration in which two band portions are inserted into the insertion holes respectively, so that the two band portions are locked and fixed together with the band locking portion.

[0030] According to this invention, by inserting the two end portions protruding on one side in the width direction into the insertion holes and pulling them to one side in the width direction, the flat electric wire can be reliably held by the band portion arranged in the plate thickness direction of the flat electric wire, and the band portion and the band locking portion can be locked and fixed together. Therefore, the operation of holding the flat electric wire in the band portion can be performed efficiently.

[0031] Furthermore, since the band fastening portion is separate from the band portion, the band fastening portion can be positioned at the center of the flat electric wire in the thickness direction regardless of the thickness of the flat electric wire, which makes it possible to more reliably prevent the flat electric wire from being bent due to being fastened by the band portion.

[0032] As another aspect of the present invention, the locking pieces at the two ends may be arranged on the same side inside the band locking portion. The above-mentioned locking pieces at the two ends may be positioned on the same side means that the locking pieces at the two ends are both positioned on the inside or outside of the band locking portion, and also includes cases where the locking piece is positioned in a position that is symmetrical to the locking piece in the other band portion, or where the locking piece and the locking piece in the other band portion are offset along the longitudinal direction of the band portion.

[0033] According to this invention, the band fastening portion can be used even when it is inverted in the thickness direction of the flat electric wire, which improves the efficiency of the assembling work of assembling the band fastening portion to the band portion.

[0034] As another aspect of the present invention, the band portion may be provided with a protrusion that protrudes from an inner surface toward the flat electric wire when the band portion holds the flat electric wire. According to this invention, the protrusions abut against the outer surface of the flat electric wire, thereby preventing the flat electric wire from shifting in the longitudinal and width directions. Furthermore, when the protrusions function as locking pieces, by inserting the band part into the insertion hole, the band part can be locked and fixed to the band locking part while preventing the flat electric wire from shifting in the longitudinal and width directions. [Effects of the Invention]

[0035] According to the present invention, it is possible to provide a band clamp and a flat electric wire with a band clamp that can firmly hold a flat electric wire while maintaining the shape of the flat electric wire. [Brief explanation of the drawings]

[0037] An embodiment of the present invention will be described below with reference to the drawings. In the flat electric wire with a band clamp 1 of this embodiment, a flat electric wire 100 to be routed in a vehicle is held by a band clamp 10. The band clamp 10 that holds the flat electric wire 100 can be routed in the vehicle by being fixed to a body panel of the vehicle. Such a band clamp 10 and a flat electric wire with a band clamp 1 will be described with reference to Figs. 1 to 9.

Figure 6(a) shows an enlarged schematic cross-sectional view of the β portion in Figure 5(a), and Figure 6(b) shows an enlarged schematic cross-sectional view of the γ portion in Figure 5(a).

[0040] 7A and 7B are explanatory diagrams illustrating the configuration of the band locking portion 50, with FIG. 7A showing a rear view of the band locking portion 50 and FIG. 7B showing a cross-sectional view taken along the arrow BB in FIG. 7A. 8 and 9 are schematic cross-sectional views illustrating a method for holding the flat electric wire 100 in the band clamp 10. Note that Fig. 8 and Fig. 9 are schematic cross-sectional views corresponding to the cross-sectional view taken along the line AA in Fig. 4(a).

[0041] Fig. 8 and Fig. 9 will be described in detail. Fig. 8(a) shows a schematic cross-sectional view before the flat electric wire 100 is sandwiched between the first band portion 31 and the second band portion 32, and Fig. 8(b) shows a schematic cross-sectional view of the flat electric wire 100 sandwiched between the first band portion 31 and the second band portion 32. Fig. 9(a) shows a schematic cross-sectional view before the band fastening portion 50 is assembled to the first band portion 31 and the second band portion 32, and Fig. 9(b) shows a schematic cross-sectional view after the band fastening portion 50 is assembled to the first band portion 31 and the second band portion 32.

[0042] 1, the up-down direction is defined as a height direction H, and the longitudinal direction of the flat electric wire 100 is defined as an extension direction L. The height direction H and the extension direction L are perpendicular to each other. The direction perpendicular to the height direction H and the extension direction L is defined as a width direction W. The lower side along the height direction H is defined as an insertion direction Hd, and the upper side along the height direction H is defined as a counter-insertion direction Hu. The directions in FIG. 1 also apply to FIGS.

[0043] 1 and 2, the flat electric wire with band clamp 1 is composed of a flat electric wire 100 to be laid in a vehicle and a band clamp 10 that holds the flat electric wire 100. Note that in FIG. 1, for convenience, only one band clamp 10 is shown for the flat electric wire 100, but in reality, a plurality of band clamps 10 are fixed to the flat electric wire 100 along the extending direction L, and each band clamp 10 is fixed to a body panel of the vehicle.

[0044] 3, the flat electric wire 100 has a plurality of conductor electric wires 110, each of which is a bundle of conducting wires, arranged along the width direction W, and is covered with an insulating resin insulating coating 120. An orthogonal cross section of the flat electric wire 100, which is orthogonal to the extension direction L, is formed in a substantially flat plate shape with its long side aligned with the width direction W and its short side aligned with the height direction H.

[0045] 2, 4, and 5, the band clamp 10 has a vehicle body fixing portion 20 that is fixed to a vehicle body panel of a vehicle, a band portion 30 that holds the flat electric wire 100 that is routed in the vehicle, a connecting portion 40 that connects the vehicle body fixing portion 20 and the band portion 30, and a band locking portion 50 that locks and fixes the band portion 30 to fix the flat electric wire 100 to the band portion 30. Note that the band locking portion 50 is configured as a separate body from the band portion 30.

[0046] The vehicle body fixing portion 20 is a so-called anchor, and comprises an insertion shaft portion 21 extending in the insertion direction Hd, a pair of locking arms 22, 22 provided at the tip of the insertion shaft portion 21, and an elastic flange 23 having a spherical cross section.

[0047] 4(a), the locking arms 22, 22 have their tips connected to the tip of the insertion shaft portion 21 and extend in the width direction W. The locking arms 22, 22 gradually move away from the insertion shaft portion 21 from the tip side (insertion direction Hd side) to the base side (anti-insertion direction Hu side) of the insertion shaft portion 21.

[0048] The locking arms 22, 22 have locking claws 24 that bulge outward from the tip (end in the insertion direction Hd) of the insertion shaft portion 21. The locking claws 24 are provided with a step portion 241 that bulges outward and a tapered portion 242 that extends in the counter-insertion direction Hu. The tapered portion 242 is formed so that the thickness on the counter-insertion direction Hu side is thinner than the thickness in the insertion direction Hd.

[0049] When the locking arms 22, 22 configured in this manner are inserted into a through-hole provided in a vehicle body panel, the boundary between the step portion 241 and the tapered portion 242 of the locking claw 24 locks onto the edge of the through-hole on the side of the vehicle body panel in the insertion direction Hd, and the vehicle body panel abuts against the elastic flange 23 on the side of the vehicle body panel opposite to the insertion direction Hu. This allows the vehicle body fixing part 20 to be fixed to the vehicle body panel (not shown).

[0050] The band portion 30 is a flexible, strip-shaped band, and as shown in Figures 2, 4 and 5, is composed of two bands: a first band portion 31 provided on one side of the connecting portion 40 in the width direction W, and a second band portion 32 provided on the other side of the connecting portion 40 in the width direction W.

[0051] As shown in Fig. 4, the first band portion 31 extends from one side of the connecting portion 40 in the width direction W along the width direction W. The outer surface of this first band portion 31 is provided with a first bending promoting portion 311 that is recessed in the plate thickness direction, and a first locking portion 312 that protrudes outward from the outer surface.

[0052] The first bending promotion portion 311 is a groove formed by recessing the outer surface of the first band portion 31 in the thickness direction of the plate in a roughly triangular shape when viewed from the side, and as shown in Figures 4(b), 5(a) and 5(b), four of them are provided at equal intervals along the longitudinal direction of the first band portion 31 on the base end side of the first band portion 31 (the side connected to the connecting portion 40).

[0053] In this way, the first band portion 31 has the first bending promoting portion 311, which is recessed in a generally triangular shape in a side view in the plate thickness direction, on the outer surface thereof, so that the portion of the first band portion 31 where the first bending promoting portion 311 is provided is easier to bend than other portions. In other words, the portion on the base end side of the first bending promoting portion 311 forms a straight portion that is difficult to bend.

[0054] The first locking portion 312 is a locking portion that is inserted into the band locking portion 50 to lock and fix the band locking portion 50, and is provided closer to the tip side than the first bending promoting portion 311. 5(b), the first locking portion 312 has a first groove 312a, which is a slight recess in the outer surface, inside the width direction of the first band portion 31, and multiple first locking pieces 312b formed in a substantially triangular shape protruding from the first groove 312a toward the outer surface of the first band portion 31. The base end side of each of the first locking pieces 312b has a substantially right-angled triangular shape that is at a substantially right angle to the first groove 312a, and the apex of the triangle protrudes outward beyond the outer surface of the first band portion 31.

[0055] As shown in FIG. 4, the second band portion 32 is a band that is longer than the first band portion 31, extends from the other side of the connecting portion 40 along the width direction W, and has a curved base end portion so that the tip faces the anti-insertion direction Hu. The outer surface of this second band portion 32 is provided with a second bending promoting portion 321 that is recessed in the plate thickness direction, and a second locking portion 322 that protrudes outward from the outer surface, similar to the first band portion 31. In addition, the inner surface of the second band portion 32 is provided with a protrusion 323 that protrudes from the outer surface toward the inner surface.

[0056] The second bending promoting portions 321 are grooves formed by recessing the outer surface of the second band portion 32 in a generally triangular shape in a side view in the thickness direction, similar to the first bending promoting portions 311. As shown in Fig. 6(a), eight second bending promoting portions 321 are provided at equal intervals along the longitudinal direction of the second band portion 32 on the base end side of the second band portion 32 (the side connected to the connecting portion 40). As shown in Figure 6(b), four second bending promotion portions 321 are provided at equal intervals along the longitudinal direction of the second band portion 32, with a predetermined distance between them and the eighth second bending promotion portion 321 from the base end side.

[0057] That is, the second band portion 32 has a total of 12 second bending promoting portions 321 provided along the longitudinal direction of the second band portion 32, and the portions where the second bending promoting portions 321 are provided are easier to bend in the plate thickness direction than other portions. In other words, a straight portion is formed between the second bending promoting portion 321 on the base end side and the second bending promoting portion 321 on the tip end side, which is less likely to bend than the portions where the second bending promoting portions 321 are provided.

[0058] 6(b), the second locking portion 322 is a locking portion that is inserted into the band locking portion 50 to lock and secure the band locking portion 50, and is provided on the distal side of the second bending promoting portion 321 that is located on the distal side. This second locking portion 322 has the same configuration as the first locking portion 312.

[0059] That is, as shown in Figure 6(b), the second locking portion 322 is configured such that, inside the width direction of the second band portion 32, a second groove 322a is formed by slightly recessing the outer surface, and multiple second locking pieces 322b formed in an approximately triangular shape protrude from this second groove 322a toward the outer surface of the first band portion 31.

[0060] The convex portion 323 protrudes in a triangular shape in a side view from the inner surface of the second band portion 32. As shown in Figures 4 and 6(a), four convex portions 323 are provided on the inner surface of the second band portion 32. More specifically, there are four convex portions in total: one in the curved portion on the base end side of the second band portion 32, one inside the approximate center portion of the second bending promoting portion 321 provided on the base end side, and two between the second bending promoting portion 321 provided on the base end side and the second bending promoting portion 321 provided on the tip end side.

[0061] 4(a), 4(b), and 5(a), the connecting part 40 is a solid housing, and is integrally fixed to the vehicle body fixing part 20 so as to extend in the insertion direction Hd. Furthermore, on the side of the connecting part 40 opposite the insertion direction Hu, a first band part 31 is integrally connected to one side in the width direction W, and a second band part 32 is integrally connected to the other side in the width direction W so as to extend along the width direction W.

[0062] The surface (upper surface 40a) of this connecting portion 40 facing the anti-insertion direction Hu is a flat surface having a width shorter than the width of the flat electric wire 100, and a protrusion 41 that protrudes slightly toward the anti-insertion direction Hu is provided along the width direction W (see Figures 2, 4(b) and 5(a)).

[0063] The band locking portion 50, which is separate from the band portion 30, is a hollow housing having a width slightly larger than that of the band portion 30 and a height sufficient compared to the thickness of the band portion 30, as shown in Figures 1, 2 and 7, and has two insertion holes 51, 51 that penetrate in the depth direction (extension direction L) along the height direction H.

[0064] The insertion holes 51, 51 are through holes having a width approximately equal to that of the band portion 30 and a height approximately 1.5 times the plate thickness of the band portion 30, and allow the first band portion 31 and the second band portion 32 to pass through, respectively. As shown in FIG. 7(b), the outer inner walls 51a, 51a of the insertion holes 51, 51 are provided with locked portions 52 that lock with the first locking portion 312 and the second locking portion 322.

[0065] 7(b), the locked portion 52 is provided with a plurality of right-angled triangular locked pieces 521 that protrude from the outer inner walls 51a of the insertion holes 51 toward the inside of the band locking portion 50. More specifically, the locked pieces 521 have a substantially right-angled triangular cross section, having a surface on one side in the width direction W that is perpendicular to the outer inner wall 51a, and an inclined surface that slopes outward from the band locking portion 50 as it extends from the perpendicular surface toward the other side in the width direction W.

[0066] 7(b), the locked pieces 521, 521 formed inside the insertion holes 51, 51 are arranged so as to be plane-symmetrical with respect to a plane along the center of the height direction H of the band locking part 50. Therefore, the band locking part 50 has no directionality with respect to the height direction H, and can be used even if it is inverted in the height direction H.

[0067] Next, a method for holding the flat electric wire 100 with the band clamp 10 will be briefly described with reference to FIGS. First, the second band portion 32 is opened relative to the first band portion 31 so that the second band portion 32 extends in the anti-insertion direction Hu (see FIG. 8(a)), and the flat electric wire 100 is placed on the upper surface 40a so that the width of the flat electric wire 100 is along the width direction W. At this time, the protruding portion 41 abuts against the insertion direction Hd of the flat electric wire 100, so that displacement of the flat electric wire 100 can be prevented.

[0068] Then, the second band portion 32 is bent so that a tip end of the second band portion 32 extends to one side in the width direction W. Here, since the second bending promoting portion 321 is provided on the base end side of the second band portion 32, i.e., the other side in the width direction W, the second band portion 32 is bent along the outer peripheral surface of the flat electric wire 100 on the other side in the width direction W. In addition, the tip side of the second band portion 32 from the second bending promoting portion 321 on the base end side follows the outer surface of the flat electric wire 100 in the width direction W.

[0069] The protrusion 323 provided on the base end side of the second band portion 32 supports the bottom portion of the other end side in the width direction W of the flat electric wire 100, and the protrusion 323 provided on the second band portion 32 abuts against the outer peripheral surface of the flat electric wire 100 (see FIG. 8(b)). Therefore, movement of the flat electric wire 100 in the width direction W and the extending direction L can be restricted.

[0070] In this state, the tips of the first band portion 31 and the second band portion 32 are pulled inward in the height direction H (see Figure 9(a)) to the extent that the ends of the first band portion 31 and the second band portion 32 protruding to one side in the width direction W can be inserted into the insertion holes 51, 51, respectively.

[0071] Then, by moving the band locking portion 50 to the other side in the width direction W along the first band portion 31 and the second band portion 32, the band locking portion 50 is positioned on one side in the width direction W of the flat electric wire 100 held by the band portion 30 (see FIG. 9(b)). Here, the first locking piece 312b and the second locking piece 322b are substantially right-angled triangular with an inclined surface on one side in the width direction W, and the locked piece 521 is substantially right-angled triangular with an inclined surface on the other side in the width direction W, so that the band locking portion 50 can be moved to the other side in the width direction W and movement of the band locking portion 50 to one side in the width direction W can be restricted.

[0072] Further, a first locking portion 312 and a second locking portion 322 are provided on the outer surfaces of the first band portion 31 and the second band portion 32, respectively, and a locked portion 52 is provided on the outer inner wall 51a of the band locking portion 50. Here, by moving the band locking portion 50 to the other side in the width direction W, the first band portion 31 and the second band portion 32 are fastened toward the inside in the height direction H (toward the flat electric wire 100) on one side of the width direction W of the flat electric wire 100.

[0073] As described above, the first band portion 31 and the second band portion 32 are bent inward in the height direction H and inserted into the insertion hole 51, and therefore, inside the band locking portion 50, a reaction force acting outward in the height direction H is generated on the first band portion 31 and the second band portion 32. This reaction force presses the first band portion 31 and the second band portion 32 against the outer inner wall 51a. Therefore, the first locking portion 312 and the second locking portion 322 can be more reliably locked with the locked portion 52.

[0074] This allows the flat electric wire 100 to be sandwiched between the first band portion 31 and the second band portion 32 along the width direction W of the flat electric wire 100, whose orthogonal cross section is substantially flat. Therefore, the flat electric wire 100 can be held by the band portion 30 while maintaining the shape of the flat electric wire 100.

[0075] Furthermore, the first locking portion 312 and the second locking portion 322 that lock onto the band locking portion 50 are provided on the outer surfaces of the first band portion 31 and the second band portion 32. Therefore, the first locking portion 312 and the second locking portion 322 inserted into the band locking portion 50 are arranged symmetrically within the band locking portion 50, with the plane along the center of the band locking portion 50 in the height direction H as the plane of symmetry. Because the locked pieces 521, 521 that lock onto the first locking portion 312 and the second locking portion 322 are also arranged symmetrically with the plane along the center of the band locking portion 50 in the height direction H, the band locking portion 50 can be used even if it is inverted in the height direction H.

[0076] Furthermore, since the band locking portion 50 is configured separately from the first band portion 31 and the second band portion 32, by inserting the first band portion 31 and the second band portion 32 into the insertion holes 51, 51, the band locking portion 50 can be positioned in the central part of the height direction H of the flat electric wire 100.

[0077] If the band fastening portion 50 is biased to one side in the height direction H, one of the first band portion 31 and the second band portion 32 will bend more excessively than the other, and a gap will likely occur between the band portion 30 and the flat electric wire 100 at the end of the flat electric wire 100 in the width direction W. Furthermore, if the band portion 30 is tightened more, the flat electric wire 100 may bend along the height direction H.

[0078] However, by arranging the band locking portion 50 in the center portion in the height direction H of the flat electric wire 100, the first band portion 31 and the second band portion 32 are bent in approximately the same manner. This makes it difficult for a gap to occur between the band portion 30 and the flat electric wire 100, and the flat electric wire 100 can be firmly held by the band portion 30.

[0079] Furthermore, even when the band portion 30 is tightened, one of the first band portion 31 and the second band portion 32 can be prevented from bending more than the other, so that external forces acting on the flat electric wire 100 in the anti-insertion direction Hu or the insertion direction Hd can be suppressed, and the flat electric wire 100 can be prevented from bending in the anti-insertion direction Hu or the insertion direction Hd.

[0080] Furthermore, since the first band portion 31 has a first bending promotion portion 311 on one side in the width direction W of the flat electric wire 100, by moving the band locking portion 50 to the other side in the width direction W, the first band portion 31 can be bent along the outer surface of one end side of the flat electric wire 100 in the width direction W.

[0081] Similarly, the second band portion 32 has a second bending promotion portion 321 on one side of the width direction W of the flat electric wire 100, so that by moving the band locking portion 50 to the other side of the width direction W, the second band portion 32 can be bent along the outer surface of one end side of the width direction W of the flat electric wire 100.

[0082] Therefore, the flat electric wire 100 can be more reliably held by the first band portion 31 and the second band portion 32, and the band locking portion 50 can be more reliably positioned in the central portion of the flat electric wire 100 in the plate thickness direction (height direction H), preventing the flat electric wire 100 from being subjected to load in the anti-insertion direction Hu or the insertion direction Hd. Therefore, the flat electric wire 100 can be more reliably prevented from bending in the height direction H while being firmly held. The first band portion 31 and the second band portion 32 extending beyond the band fastening portion 50 in the width direction W are cut off at the end of the band fastening portion 50 on one side in the width direction W (not shown).

[0083] Furthermore, the band clamp 10 (flat electric wire 1 with band clamp) holding the flat electric wire 100 can be fixed to the vehicle panel by inserting the vehicle body fixing part 20 into a through-hole provided in the vehicle panel. This allows the flat electric wire 100 to be routed to the vehicle panel so that the width of the flat electric wire 100 is parallel to the vehicle panel.

[0084] In this way, the band clamp 10 has a vehicle body fixing portion 20 that is fixed to a vehicle body panel in a vehicle, a band portion 30 (first band portion 31 and second band portion 32) that holds the flat electric wire 100 along the outer surface of the flat electric wire 100 to be routed in the vehicle, a connecting portion 40 that connects the vehicle body fixing portion 20 to the first band portion 31 and the second band portion 32, and a band locking portion 50 that locks and fixes the band portion 30 that holds the flat electric wire 100, and the band locking portion 50 is arranged on one side in the width direction W of the flat electric wire 100 that it holds.

[0085] As a result, by fastening and fixing the band portion 30 with the band fastening portion 50, the first band portion 31 and the second band portion 32 can hold the flat electric wire 100 so that they are aligned with the outer surface of the flat electric wire 100. Therefore, the flat electric wire 100 can be firmly held by the band portion 30, and bending of the flat electric wire 100 in the plate thickness direction (height direction H) can be prevented. Therefore, the shape of the flat electric wire 100 can be maintained, the flat electric wire 100 can be fixed to a predetermined position on the vehicle without applying a load to the flat electric wire 100, the height of the flat electric wire 100 in the plate thickness direction can be reduced, and the effects of the flat electric wire 100 such as improved heat dissipation can be obtained.

[0086] Furthermore, the band portion 30 (the first band portion 31 and the second band portion 32) holds the flat electric wire 100 so that the width direction W is parallel to the vehicle body panel, thereby allowing the flat electric wire 100 to be routed so that the width direction W of the flat electric wire 100 is along the vehicle body panel. Therefore, the vehicle space around the routed flat electric wire 100 can be effectively utilized.

[0087] Furthermore, the second band portion 32 has a second locking portion 322 on the other side in the width direction W that promotes bending, so that the second band portion 32 can be bent on the other side in the width direction W in accordance with the outer shape of the other side in the width direction W of the flat electric wire 100.

[0088] In other words, since the second band portion 32 can be aligned along a portion of the surface of the flat electric wire 100 along the plate thickness direction, it is possible to prevent a gap from being formed between the second band portion 32 and the flat electric wire 100, and the flat electric wire 100 can be securely held by the first band portion 31 and the second band portion 32.

[0089] Furthermore, the first band portion 31 and the second band portion 32 are provided with a first locking portion 312 and a second locking portion 322 on one side in the width direction W. Therefore, the first band portion 31 and the second band portion 32 can be bent on one side in the width direction W of the first band portion 31 and the second band portion 32 to fit the outer surface of the flat electric wire 100.

[0090] Therefore, the first band portion 31 and the second band portion 32 can be bent along the outer surface of the flat electric wire 100 in both width directions W, and the flat electric wire 100 can be more securely held by the first band portion 31 and the second band portion 32.

[0091] Furthermore, the first locking portion 312 and the second locking portion 322 are configured as grooves formed by recessing the outer surfaces of the first band portion 31 and the second band portion 32, respectively, along the longitudinal direction (extension direction L) of the flat electric wire 100, thereby enabling the first locking portion 312 and the second locking portion 322 to be formed with a simple structure. Therefore, the first band portion 31 and the second band portion 32 can be bent along the outer surface of the flat electric wire 100 with a simple structure, enabling the flat electric wire 100 to be held more firmly.

[0092] Furthermore, since a large number of first locking portions 312 and second locking portions 322 are arranged along the longitudinal direction of the first band portion 31 and the second band portion 32, the first band portion 31 and the second band portion 32 can be bent along the outer surface of the flat electric wire 100 even for various flat electric wires 100 having different plate thicknesses and lengths in the width direction W.

[0093] Furthermore, the first band portion 31 and the second band portion 32 are provided with a first locking portion 312 and a second locking portion 322, and the band locking portion 50 is provided with insertion holes 51, 51 for inserting one end of the first band portion 31 and the second band portion 32, and locked portions 52, 52 that lock with the first locking portion 312 and the second locking portion 322 of the first band portion 31 and the second band portion 32 inserted into the insertion holes 51, 51.

[0094] As a result, by simply pulling the first band portion 31 and the second band portion 32 inserted into the insertion holes 51, 51 to one side in the width direction W, the first band portion 31 and the second band portion 32 can be locked and fixed to the band locking portion 50 while preventing unintended loosening of the fastening of the first band portion 31 and the second band portion 32 to the flat electric wire 100. Therefore, the operation of holding the flat electric wire 100 in the band portion 30 can be performed efficiently.

[0095] Furthermore, since the first locking portion 312 and the second locking portion 322 are provided on the outer surfaces of the first band portion 31 and the second band portion 32 that hold the flat electric wire 100, the first band portion 31 and the second band portion 32 can be more reliably locked and fixed to the band locking portion 50.

[0096] More specifically, since the first band portion 31 and the second band portion 32 are bent inward in the plate thickness direction of the flat electric wire 100 and inserted into the insertion hole 51, a reaction force acting outward in the plate thickness direction acts on the first band portion 31 and the second band portion 32 inside the insertion hole 51. This reaction force ensures that the inner surface (outer inner wall 51a) of the band locking portion 50 in the plate thickness direction and the outer surfaces of the first band portion 31 and the second band portion 32 are in contact with each other, so that the first locking portion 312 and the second locking portion 322 can be more reliably locked to the locked portion 52.

[0097] Furthermore, the band locking portion 50 may be constructed separately from the band portion 30, and the insertion holes 51, 51 in the band locking portion 50 may each be inserted with two ends of the first band portion 31 and the second band portion 32 protruding on at least one side of the width direction W.

[0098] As a result, by inserting the two end portions protruding on one side in the width direction W into the insertion holes 51, 51 and pulling them to one side in the width direction W, the flat electric wire 100 can be securely sandwiched and held by the first band portion 31 and the second band portion 32 arranged in the plate thickness direction (height direction H) of the flat electric wire 100, and the first band portion 31 and the second band portion 32 can be collectively locked and fixed to the band locking portion 50. Therefore, the operation of holding the flat electric wire 100 in the band portion 30 can be performed efficiently.

[0099] Furthermore, since the band fastening portion 50 is separate from the first band portion 31 and the second band portion 32, the band fastening portion 50 can be disposed in the central portion in the short direction of the orthogonal cross section of the flat electric wire 100, regardless of the plate thickness of the flat electric wire 100. Therefore, bending of the flat electric wire 100 due to fastening of the flat electric wire 100 by the first band portion 31 and the second band portion 32 can be more reliably prevented.

[0100] Furthermore, the first locking portion 312 provided on the first band portion 31 is disposed inside the band locking portion 50 so as to be plane-symmetrical with respect to the second locking portion 322 provided on the adjacent second band portion 32, so that the band locking portion 50 can be used even when it is inverted in the thickness direction of the flat electric wire 100. This improves the efficiency of the assembly work of assembling the band locking portion 50 to the first band portion 31 and the second band portion 32.

[0101] In addition, the second band portion 32 has a protrusion 323 that protrudes from the inner surface toward the flat electric wire 100 when holding the flat electric wire 100, and the protrusion 323 abuts against the outer surface of the flat electric wire 100, thereby preventing the flat electric wire 100 from shifting in the longitudinal direction and width direction W.

[0102] In correspondence between the configuration of this invention and the above-mentioned embodiment, The vehicle body fixing part corresponds to the vehicle body fixing part 20, and similarly The flat wire corresponds to the flat wire 100, The band portion corresponds to the band portion 30 (the first band portion 31 and the second band portion 32), The connecting portion corresponds to the connecting portion 40, The band locking portion corresponds to the band locking portion 50, The width direction corresponds to the width direction W, The band clamp is compatible with band clamp 10. The bending promoting portion corresponds to the first locking portion 312 and the second locking portion 322, The locking pieces correspond to the first bending promoting portion 311 and the second bending promoting portion 321, The insertion hole corresponds to the insertion hole 51, The locked portion corresponds to the locked portion 52, The protrusion corresponds to the protrusion 323, The flat electric wire with band clamp corresponds to the flat electric wire with band clamp 1, The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained.

[0103] For example, in this embodiment, the vehicle body fixing portion 20 is an anchor that is inserted into a through hole provided in the vehicle body panel to fix it, but it may also be a stud bolt that is inserted into a bolt fixed to the vehicle body panel to fix it.

[0104] In addition, in this embodiment, the band portion 30 is configured to have two bands, the first band portion 31 and the second band portion 32, connected to the connecting portion 40, but it is not necessary to have two bands. For example, the connecting portion 40 may have a locking insertion hole through which the band is inserted and locked, and one band portion 30 may be inserted into the locking insertion hole and wound around the connecting portion 40, or multiple band portions 30 may be connected to the connecting portion 40.

[0105] For example, as shown in Fig. 10(a), a flat electric wire with a band clamp 1x will be described, in which a flat electric wire 100 is held by a band clamp 10x. The band clamp 10x has a first band portion 31x and a second band portion 32x having the same configuration as the first band portion 31, which are connected to a connecting portion 40, and a third band portion 33x having substantially the same configuration as the first band portion 31x and separate from the connecting portion 40. The flat electric wire 100 is held by the first band portion 31x, the second band portion 32x, and the third band portion 33x.

[0106] A flat electric wire with a band clamp 1x will be briefly described below with reference to Fig. 10(a). Fig. 10(a) shows a schematic cross-sectional view of a band clamp 10x, which is another embodiment, corresponding to Fig. 8 and Fig. 9. In the band clamp 10x, the same components as those in the band clamp 10 are designated by the same reference numerals, and their description will be omitted.

[0107] As shown in FIG. 10(a), the band clamp 10x is made up of a vehicle body fixing portion 20, a connecting portion 40, a band locking portion 50, a first band portion 31x, a second band portion 32x, and a third band portion 33x. A first band portion 31x and a second band portion 32x, which have the same configuration as the first band portion 31, are connected to the connecting portion 40 along the width direction W. A first bending promoting portion 311 and a first locking portion 312 are provided on the outer surfaces of the first band portion 31x and the second band portion 32x.

[0108] Furthermore, the third band portion 33x, which is separate from the connecting portion 40, has third locking portions 332 provided at both longitudinal end portions corresponding to the first locking portions 312. Furthermore, the third band portion 33x has third bending promoting portions 331 corresponding to the first bending promoting portions 311 provided on the proximal end sides of the third locking portions 332.

[0109] In such a band clamp 10x, the flat electric wire 100 is placed on the connecting portion 40 (upper surface 40a), and the first band portion 31x and the third band portion 33x are fastened and fixed with the band fastening portion 50 on one side in the width direction W, and the second band portion 32x and the third band portion 33x are fastened and fixed with the band fastening portion 50 on the other side in the width direction W, so that the flat electric wire 100 can be held by the first band portion 31x, the second band portion 32x, and the third band portion 33x.

[0110] Here, the first band portion 31x and the second band portion 32x are aligned along the width of the flat electric wire 100 on the side in the insertion direction Hd, and the third band portion 33x is aligned along the width of the flat electric wire 100 on the side opposite to the insertion direction Hu. Therefore, the flat electric wire 100 is firmly held by the first band portion 31x, the second band portion 32x, and the third band portion 33x.

[0111] In addition, since the first band portion 31x, the second band portion 32x, and the third band portion 33x have the first bending promoting portion 311 and the third bending promoting portion 331, the flat electric wire 100 can be held more firmly along the outer surface of the flat electric wire 100.

[0112] In addition, the first band portion 31x and the third band portion 33x extending to one side in the width direction W from the band engaging portion 50, and the second band portion 32x and the third band portion 33x extending to the other side in the width direction W from the band engaging portion 50 are cut (not shown). This provides a band clamp-equipped flat electric wire 1x in which the flat electric wire 100 is held by the band clamp 10x, and the flat electric wire 100 can be fixed to the vehicle body panel.

[0113] Furthermore, in this embodiment, the band fastening portion 50 is provided separately from the band portion 30, but the band fastening portion 50 may be configured integrally with the band portion 30, for example, like a cable tie with a buckle. Even in this case, the band portion 30 can firmly hold the flat electric wire 100. Furthermore, the band fastening portion 50 may be provided integrally with the connecting portion 40.

[0114] In addition, in this embodiment, the flat electric wire 100 is held by the band portion 30 so that the width direction W is parallel to the vehicle body panel, but the flat electric wire 100 may be held by the band portion 30 so that the width direction W is perpendicular to the vehicle body panel. That is, as shown in the cross-sectional view of Fig. 10(b), the flat electric wire 100 may be held along the insertion direction (height direction H) of the vehicle body fixing portion 20. FIG. 10(b) shows a schematic cross-sectional view corresponding to FIG. 8 and FIG.

[0115] In addition, in this embodiment, the second bending promotion portion 321 is provided on both sides of the width direction W of the second band portion 32, but it is not necessarily necessary to provide it on both sides, and the second bending promotion portion 321 may be provided only on one side or the other side of the width direction W.

[0116] Furthermore, the first bending promoting portions 311 and the second bending promoting portions 321 do not need to be equally spaced along the longitudinal direction of the first band portion 31 and the second band portion 32, but may be arranged at unequal intervals, or may be provided over the entire first band portion 31 and the second band portion 32. Furthermore, the depth of the grooves of the first locking portion 312 and the second locking portion 322 do not need to be uniform, but may be uneven.

[0117] In addition, in this embodiment, the band locking portion 50 is configured to lock each of the first band portion 31 and the second band portion 32 inserted into the insertion hole 51, but the band portion 30 and the band locking portion 50 may be locked and fixed by inserting two band portions 30 (the first band portion 31 and the second band portion 32) into the insertion hole 51.

[0118] Furthermore, in this embodiment, the first locking portion 312 and the second locking portion 322 are provided on the outer surfaces of the first band portion 31 and the second band portion 32, but the first locking portion 312 and the second locking portion 322 may be provided on the inner surfaces of the first band portion 31 and the second band portion 32. In this case, the band locking portion 50 that is locked and fixed to the band portion 30 also has a locked portion 52 provided on the inner side in the height direction H.

[0119] Furthermore, when the convex portion 323 is made to function as the second locking portion 322, by inserting the second band portion 32 into the insertion hole 51, the second band portion 32 can be locked and fixed to the band locking portion 50 while preventing the flat electric wire 100 from shifting out of position.

[0120] Furthermore, in this embodiment, the first locking portion 312 and the second locking portion 322 are arranged so as to be plane-symmetrical inside the band locking portion 50, but for example, the first locking piece 312b and the second locking piece 322b may be arranged so as to be offset in the width direction W. In other words, the locked pieces 521, 521 provided inside the band locking portion 50 may be arranged so as to be offset from each other along the width direction W. [Explanation of symbols]
