Description

The present invention relates to, for example, a band clamp for attaching a wire harness to a vehicle body, a wire harness held by the band clamp, and a harness manufacturing method using the band clamp.

For example, as a jig for wiring a wire harness to a vehicle, a band clamp is used that includes a harness holding portion that holds the wire harness and a vehicle attachment portion that is attached to a predetermined attachment location on the vehicle. The harness holding portion of the band clamp is composed of a band portion wound around the outer circumference of the wire harness and a buckle portion fixing the band portion while being wound around the wire harness.

The band clamp can hold the wire harness by fixing the band portion with the buckle portion while being wound around the wire harness. The wire harness can be routed in the vehicle by using such a band clamp and attaching the vehicle mounting portion to a position on the wiring route in the vehicle body while the wire harness is held by the harness holding portion.

A wire harness consists of a cable bundled with multiple electric wires, and is a component that connects to a predetermined connection destination (electronic equipment, battery, etc.). Depending on the situation, the connection mode may have to be changed. Therefore, the wire harness has a group of electric wires that serve as a trunk (trunk line) and a group of electric wires that are smaller than the trunk line and branch from the trunk line (branch lines). A branch line is branched from the main line and connected to the corresponding connection destination. In a wire harness having this main line and branch lines, it is required to hold not only the main line but also the branch lines together.

As such a band clamp, for example, Patent Literature 1 discloses a band clamp in which a clip-shaped elastic piece for attaching and detaching a branch wire is protruded from the outer periphery of the band portion. According to the band clamp disclosed in Patent Literature 1, it is possible to collectively hold the branch wires with the band clamp by holding the branch wires with the clip-shaped elastic pieces while holding the trunk wires with the band portion. It is

However, since the band clamp is configured to hold the branch wire with a clip-shaped elastic piece, the holding force is not strong, and there is a risk that the branch wire may fall off the elastic piece due to vibrations during transportation or wiring work. there were.

Therefore, it is envisioned that not only the trunk line but also the branch lines will be wrapped together and fixed by the band part, using the function of the band clamp, which fixes the band part while it is wound around the wire harness by the buckle part. According to this, although there is no risk of the branch line falling off, there is a risk that the branch line will be displaced in the circumferential direction of the main line during or after fixing with the band portion. Therefore, due to such misalignment of the branch wire, the position of the branch wire in the circumferential direction is different at each fixing point with the band clamp, resulting in excess slack in the branch wire or a short length due to kinking. , there was a risk that the wiring work would be hindered.

SUMMARY OF THE INVENTION In view of the above-described problems, an object of the present invention is to provide a band clamp, a wire harness, and a method of manufacturing a harness that can suppress drop-off and displacement of branch wires.

A band clamp of the present invention is a band clamp comprising a harness holding portion for holding a wire harness and a vehicle mounting portion for mounting at a predetermined mounting location in a vehicle, wherein the wire harness is attached to a main line and from the main line. The harness holding portion includes a band portion wound around the outer circumference of the wire harness along which the branch wire is along the main line, and the band portion fixed while being wound around the wire harness. and a buckle portion, and on the inner surface of the band portion, a plurality of convex portions extending in a crossing direction crossing the longitudinal direction of the band portion are provided at predetermined intervals in the longitudinal direction. and

The above-mentioned predetermined interval is not necessarily limited to being larger than the diameter of the branch wire, and may be smaller than the diameter of the branch wire. At least part of the branch wire can be received between the protrusions even if the diameter of the branch wire is smaller than the diameter of the branch wire. It is possible to suppress positional deviation of the line in the circumferential direction.

According to this invention, the band portion can be wound around the outer circumference of the trunk line and fixed with the buckle portion in a state where the branch line is arranged between the convex portions adjacent in the longitudinal direction. Thereby, not only the trunk line but also the branch line can be held by the band portion, and the branch line can be prevented from falling off. positional deviation in the circumferential direction can be suppressed.

As an aspect of the present invention, the convex portion may be provided in a predetermined range on the base portion side of the band portion on the buckle portion side.
According to this invention, since the distal end side of the band portion opposite to the base portion side is used for fixing the band portion by the buckle portion, the convex portion provided on the base side of the band portion is It is possible to prevent obstruction of fixing of the band portion by the buckle portion.

As an aspect of the present invention, the predetermined range in which the convex portion is provided in the band portion may be a range having a length of half or less of the band portion.
According to the present invention, it is possible to further prevent the convex portion from hindering the fixing of the band portion by the buckle portion.

As a mode of this invention, the buckle side convex part may be provided in the side where the band part holds the wire harness in the buckle part.
According to this aspect of the invention, since the buckle portion is provided with the buckle-side convex portion, the branch wire can be arranged in a manner capable of suppressing displacement in the circumferential direction, even at the portion of the trunk line facing the buckle portion. . As a result, it is possible to more flexibly deal with the arrangement of the branch lines.

As an aspect of the present invention, the crossing direction is defined as a first crossing direction, and the convex portion is defined as a first convexity, and is provided on the inner surface of the band portion in a second crossing direction crossing the first crossing direction. A second protrusion may be provided.

According to the present invention, while the first protrusion suppresses the positional deviation of the branch wire in the circumferential direction, the second protrusion can be made to bite into the trunk line, thereby preventing the longitudinal positional deviation of the trunk line. can be suppressed.

As an aspect of the present invention, the first protrusion and the second protrusion may be integrally formed.
The above-mentioned integrally formed includes the case where the first convex portion and the second convex portion are connected at a part thereof, for example, the first convex portion and the second convex portion It includes a case where they are united to form an S-shape, a U-shape, an H-shape, an L-shape, or the like.

According to the present invention, since the first protrusion and the second protrusion are integrally formed, even if a force acting on the outer side in the circumferential direction acts on the first protrusion in contact with the branch wire. , the first protrusion is reinforced by the second protrusion, and deformation of the first protrusion to the outer side in the circumferential direction is suppressed. Accordingly, it is possible to further restrict the movement of the branch wire in the circumferential direction by the first convex portion, thereby further suppressing the displacement of the branch wire in the circumferential direction.

As an aspect of the present invention, the second convex portion may be arranged so as to straddle the first convex portion in the second intersecting direction.
According to the present invention, since a T-shaped or cross-shaped convex portion is formed by the first convex portion and the second convex portion, the branch line is arranged between the second convex portions. It is possible to suppress positional displacement of the branch wires in the circumferential direction.

Further, by forming the first convex portion and the second convex portion to have a T-shaped or cross-shaped convex portion, it is possible to suppress the load on the trunk line while suppressing the positional deviation in the longitudinal direction of the trunk line. .
More specifically, when the band portion is wound around the trunk line, the area in contact with the trunk line can be increased compared to the case where only the second convex portion abuts on the trunk line. When the strength of the force with which the band portion tightens the trunk line is the same, the larger the contact area, the more the depth of the convex portion biting into the trunk line is suppressed. Therefore, by arranging the second convex portion astride the first convex portion in the second intersecting direction to form a T-shaped or cross-shaped convex portion, the positional deviation in the longitudinal direction of the trunk can be reduced. It is possible to suppress the load on the main line while suppressing the load.

As a mode of this invention, the first protrusion and the second protrusion may be separated from each other.
According to the present invention, since there is a spaced region between the first convex portion and the second convex portion, the combination of the band portion can be reduced, and the first convex portion and the second convex portion are provided. However, the operation of winding the band portion around the main line can be easily performed.

As an aspect of the present invention, a space may be formed between the first protrusions spaced apart by a predetermined distance in the longitudinal direction, and the second protrusion may be arranged in the space.
According to the present invention, when the branch wire is arranged in the space portion, the first protrusion can restrict the movement of the branch wire in the circumferential direction, and the second protrusion can be bitten into the branch wire. Therefore, the movement of the branch wire in the longitudinal direction can also be restricted.

As a mode of this invention, the second convex portion may be arranged in one of the intervals adjacent in the longitudinal direction.
According to this invention, compared with the spacing part where the second protrusion is placed, the spacing part where the second protrusion is not placed can be easily deformed. And, it is possible to easily perform the work of winding the band portion around the main line even though the second convex portion is provided.

Further, in the case where the second protrusion is formed integrally with the first protrusion to suppress deformation of the first protrusion in the circumferential direction, the interval for arranging the branch line The space can be efficiently used by alternately providing the portions and the spacing portions provided with the second protrusions to reinforce the first protrusions.

As an aspect of the present invention, the second convex portion may be formed such that an orthogonal cross section orthogonal to the first cross direction is tapered toward the projecting direction.
According to the present invention, since the second protrusion tapers in the projecting direction, when the branch line is arranged on the second protrusion, the second protrusion protrudes without being tapered. , the range in which the second protrusion bites into the branch wire can be suppressed, and the load on the branch wire can be suppressed.

Further, when the first convex portion and the second convex portion are provided apart from each other, the second convex portion has a tapered shape. Therefore, even when the band portion is bent, the first convex portion The second convex portion is less likely to come into contact with the portion, and inhibition of bending of the band portion can be suppressed.

As an aspect of the present invention, the harness holding portion and the vehicle attachment portion may be configured separately.
According to this invention, the convex portion can be arranged at a position corresponding to the branch line.

More specifically, the arrangement of the branch line with respect to the main line is generally determined based on the vehicle mounting portion. It is preferable to dispose the convex portion at the position of the branch line determined in this way. However, there are various positions where the branch lines should be arranged, and it may be difficult to provide the convex portions so as to cover all of them.

On the other hand, by configuring the harness holding portion and the vehicle mounting portion separately, the arrangement of the harness holding portion with respect to the vehicle mounting portion can be adjusted. Accordingly, the harness holding portion can be flexibly arranged according to the arrangement of the branch wire determined based on the vehicle mounting portion, and the convex portion can be arranged at a position corresponding to the branch wire. .

Further, according to the present invention, the harness holding portion of the band clamp described above holds the trunk line and the branch line, and the branch line along the axial direction of the trunk line is located on the opposite side of the vehicle mounting portion in the cross section of the trunk line. It is characterized by being a wire harness arranged in a half cross section range of.

Further, according to the present invention, the harness holding portion of the band clamp described above holds the trunk line and the branch line, and the branch line along the axial direction of the trunk line is located on the side of the cross section of the trunk line on which the vehicle mounting portion is located. It is characterized by being a wire harness arranged in a half cross section range of.

According to these inventions, the band portion can be wound around the outer periphery of the trunk line and fixed with the buckle portion in a state in which the branch line is arranged between the convex portions adjacent in the longitudinal direction. Thereby, the wire harness can be routed by surely arranging the branch wire in the half cross-sectional range on the side where the vehicle mounting portion is present in the cross section of the trunk line or on the opposite side.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
First, the band clamp 1 of the first embodiment will be briefly described with reference to FIGS. 1 to 4. FIG. 1 shows a schematic perspective view of the band clamp 1 in use, FIGS. 2 and 3 each show an explanatory view of the band clamp 1, and FIG. 4 shows an explanatory view of the band clamp 1 in use.

Specifically, FIG. 1 is a schematic perspective view showing a state in which a wire harness 100 is held by a band clamp 1 and the band clamp 1 holding the wire harness 100 is attached to a predetermined attachment location 201 in a vehicle 200. FIG.

Moreover, FIG. 2 shows an explanatory view of the band clamp 1 in a state in which the band portion 10 constituting the band clamp 1 is unfolded. FIG. 2(a) shows a front view of the band clamp 1 in the same state (a view of the band clamp 1 from the axial direction of the wire harness 100 when attached to the wire harness 100), and FIG. The top view of the band clamp 1 in the same state (viewed from the radially inner side when wound around the wire harness 100) is shown.

FIG. 3 shows a cross-sectional view for explaining the internal structure of the buckle portion 20 with the band portion 10 fixed, and FIG. 4 shows the band clamp 1 with the band portion 10 wound around the wire harness 100 and fixed. The front view (the figure which looked at the band clamp 1 from the axial direction of the wire harness 100) is shown.

As shown in FIG. 1, the wire harness 100 is composed of a cable in which a plurality of electric wires are bundled, and one end of which is connected to a predetermined connection destination (electronic equipment, battery, etc.). In this wire harness 100, the connection mode may be changed according to the specification of the connection destination and the specification/destination of the vehicle body. Therefore, the wire harness 100 has a trunk line 110 that is a group of electric wires serving as a trunk, and branch lines 120 that are a group of electric wires that are smaller in diameter than the trunk line 110 and can branch from the trunk line 110 as necessary. A line 120 runs along the line. By adopting such a configuration, it is possible to branch off the corresponding branch line 120 from the trunk line 110 and change the connection mode according to the connection destination and the specification/destination of the vehicle body.

The band clamp 1 is a jig for fixing the wire harness 100 to the vehicle 200, and is used to route the wire harness 100 to the vehicle. This band clamp 1 is composed of a harness holding portion 2 that holds a wire harness 100 and a vehicle mounting portion 3 that is mounted to a mounting portion 201 . The vehicle mounting portion 3 is configured by an anchor that is inserted into the mounting portion 201 of the vehicle 200 .

With such a band clamp 1, as shown in FIG. can be fixed against

As shown in FIGS. 2A and 2B, the harness holding portion 2 includes a band portion 10 wound around the outer circumference of the wire harness 100 and a buckle portion fixing the band portion 10 while being wound around the wire harness 100. 20.

Specifically, the band portion 10 is provided with an engaged portion 11 to be engaged with the buckle portion 20 on the distal end side thereof. The engaged portion 11 is configured by forming a plurality of engaged projections 11 a continuously in the longitudinal direction L of the band portion 10 . As shown in FIG. 3, the buckle portion 20 is formed with an insertion hole 21 through which the band portion 10 can be inserted. 22 are formed.

The band portion 10 and the buckle portion 20 configured in this way are connected to the wire harness 100 by engaging the engaging protrusions 22 with any engaged protrusions 11 a of the band portion 10 inserted through the insertion holes 21 . can be fixed in a state in which the band portion 10 is wrapped around the .

In the harness holding portion 2 configured as described above, the band portion 10 is provided with the convex portion 30 so that not only the trunk line 110 but also the branch line 120 can be wrapped together by the band portion 10 . As a result, with respect to the wire harness 100 in which the branch wire 120 runs along the trunk line 110, the branch wire 120 can be prevented from falling off.

More specifically, the convex portion 30 extends in the cross direction X that intersects the longitudinal direction L of the band portion 10 on the inner surface of the band portion 10, which is the inner surface in the radial direction when the wire harness 100 is wound. In addition, a plurality of them are provided in the longitudinal direction L at predetermined intervals. Specifically, six protrusions 30 are provided, and five spacings 31 are provided when the spacings 31 are between the protrusions 30 spaced apart by a predetermined distance in the longitudinal direction L. .

Describing the shape of the projections 30 , in the band clamp 1 , the cross direction X is a direction perpendicular to the longitudinal direction L, and each projection 30 is formed over the entire length of the band portion 10 in the cross direction X. Each projection 30 is provided with a projection height that does not exceed the diameter of the branch wire 120 . In addition, each convex portion 30 is provided in a predetermined range on the base side of the band portion 10 on the side of the buckle portion 20, more specifically, in a range Lb having a length equal to or less than half the total length La of the band portion 10. . The interval between the convex portions 30 (in other words, the width of the interval portion 31 in the longitudinal direction L) is larger than the diameter of the branch wire 120 .

When winding the band portion 10 around the wire harness 100, the band clamp 1 having such a convex portion 30 holds the band portion 10 in a state where the branch wire 120 is arranged in the interval portion 31 as shown in FIG. It is wrapped around the outer circumference of 110 and fixed with the buckle part 20 . As a result, the protrusions 30 are arranged on both the left and right sides of the branch line 120 .

Also, in FIG. 4, the branch line 120 is arranged in the space 31 closest to the base, but the position on the peripheral surface of the trunk line 110 where the branch line 120 should be arranged may be a position closer to the tip side. When the position where the branch line 120 should be arranged changes, the branch line 120 can be arranged in the space part 31 corresponding to the position.

According to the band clamp 1 configured in this manner, the band portion 10 can be wound around the outer periphery of the trunk wire 110 and fixed with the buckle portion 20 in a state where the branch wire 120 is arranged in the interval portion 31 . As a result, not only the main line 110 but also the branch line 120 are held by the band portion 10, and the branch line 120 can be prevented from falling off. 120 in the circumferential direction C can be suppressed.

Further, while the engaged portion 11 on the distal end side of the band portion 10 is used for fixing the band portion 10 by the buckle portion 20, the convex portion 30 extends over a predetermined range on the base portion side, particularly half the total length La of the band portion 10. It is in the following length range Lb. Therefore, it is possible to prevent the convex portion 30 from hindering the fixing of the band portion 10 by the buckle portion 20 .

Since the band clamp 1 is provided with two or more spacing portions 31, the spacing portion 31 for arranging the branch wire 120 is selected according to the position on the peripheral surface of the main line 110 where the branch wire 120 is to be arranged. , and the positional relationship between the main line 110 and the branch line 120 can be flexibly accommodated.

Therefore, when the band clamp 1 is attached to the wire harness 100 by appropriately changing the interval 31 in which the branch wires 120 are arranged, the trunk wire 110 and the branch wires 120 can be held by the harness holding portion 2 of the band clamp 1 . In addition, the branch line 120 along the axial direction of the trunk line 110 is attached to the trunk line 110 by the wire harness 100 arranged in the half cross-sectional range on the opposite side of the vehicle mounting portion 3 in the cross section of the trunk line 110 or by the harness holding portion 2 of the band clamp 1. 110 and branch line 120 can be held. Therefore, it is possible to obtain the wire harness 100 in which the branch wire 120 along the axial direction of the trunk line 110 is arranged in the half-sectional range of the cross section of the trunk line 110 on the side where the vehicle mounting portion 3 is located.

In the wire harness 100 to which the band clamp 1 is attached in this way, even if the arrangement of the branch wires 120 is different, the branch wires 120 can be arranged at the intervals 31 according to the arrangement. Therefore, the wire harness 100 in which the branch wire 120 is surely arranged in a necessary range, such as the side where the vehicle attachment portion 3 is present or the opposite side in the cross section of the trunk line 110 , can be routed in the vehicle 200 .

Next, a band clamp 1a according to a second embodiment shown in FIGS. 5 and 6 will be described.
FIG. 5 shows an explanatory view of the band clamp 1a of the second embodiment. Specifically, FIG. 5(a) shows the inner surface side of the band clamp 1a in a state in which the band portion 10 constituting the band clamp 1a is unfolded. A schematic perspective view is shown, and FIG. 5(b) shows a front view of the band clamp 1a. FIG. 6 shows an explanatory view of the state of use of the band clamp 1a of the second embodiment, specifically, a front view of the band clamp 1a of the second embodiment in which the band portion 10 is wound around the wire harness 100 and fixed. indicates

The band clamp 1a has a configuration similar to that of the band clamp 1 described above, and provides similar effects, but has a characteristic configuration that provides additional effects. In the following, in the band clamp 1a, the same components as those of the band clamp 1 are denoted by the same reference numerals, and the description thereof is omitted, and the characteristic structure will be described in detail. In the description of other embodiments that will be described later, similarly, the characteristic configuration of each embodiment will be described.

As shown in FIGS. 5 and 6, the band clamp 1a includes, on the inner surface of the band portion 10, a first convex portion 40 extending in a first intersecting direction X1 that intersects the longitudinal direction L of the band portion 10; A second protrusion 50 is provided extending in a second cross direction X2 crossing the first cross direction X1.

The first convex portion 40 includes a one-side first convex portion 41 extending from one side of the band portion 10 in the first intersecting direction X1 to the intermediate portion, and a first convex portion 41 extending from the other side of the band portion 10 in the first intersecting direction X1 to the intermediate portion. It is composed of the other side first convex portion 42 . The first protrusions 41 on one side and the first protrusions 42 on the other side are alternately provided in the longitudinal direction L at predetermined intervals.

The second convex portion 50 is located between the first convex portions separated by a predetermined interval in the longitudinal direction L, more specifically, between the adjacent one side first convex portion 41 and the other side first convex portion 42. is provided in the spacing portion 43 . The one-side first convex portion 41 and the other-side first convex portion 42 and the second convex portion 50 are separated from each other by a predetermined distance along the longitudinal direction L. That is, the one-side first convex portion 41 and the other-side first convex portion 42 are separated from the second convex portion 50 .

The second convex portion 50 has an orthogonal cross section perpendicular to the first cross direction X1 that is tapered toward the projecting direction. Specifically, the second convex portion 50 has an arc shape when viewed from the front. It is formed in a kamaboko shape. Then, as shown in FIG. 5B, the second protrusion 50 has a maximum protrusion height lower than the protrusion height of the first protrusion 40 .

In the band clamp 1a having such a second convex portion 50, as shown in FIG. 5B, the branch wire 120 is brought into contact with the second convex portion 50 existing in the interval portion 43 where the branch wire 120 is arranged. In this state, the band portion 10 is wrapped around the outer circumference of the main line 110 and fixed with the buckle portion 20 . Since the maximum protrusion height of the second protrusion 50 is lower than the protrusion height of the first protrusion 40, as shown in FIG. The wire harness 100 is held by the band clamp 1a in a state in which the first convex portions 40 are arranged on both sides of the wire harness 120 in the circumferential direction C. As shown in FIG.

According to the band clamp 1a configured in this way, as shown in FIG. positional deviation in the circumferential direction C can be suppressed. In addition, since the branch wire 120 is held by the band portion 10 in a state in which the second convex portion 50 extending in the second crossing direction X2 orthogonal to the axial direction of the branch wire 120 is in contact with the branch wire 120, the branch wire 120 positional deviation in the axial direction can also be suppressed.

In addition, since there is a separation area between the first protrusion 40 and the second protrusion 50, the band section 10 can be easily deformed in this separation area. In particular, in the band clamp 1a, since the second convex portion 50 is tapered, even when the band portion 10 is bent, the second convex portion 50 is less likely to come into contact with the first convex portion 40. Inhibition of bending of the portion 10 can be further suppressed. As a result, the operation of winding the band portion 10 around the main line 110 can be easily performed.

Next, a band clamp 1b of a third embodiment shown in FIGS. 7 and 8 will be described.
FIG. 7 shows an explanatory view of the band clamp 1b of the third embodiment. Specifically, FIG. 7(a) shows the inner surface side of the band clamp 1b in a state in which the band portion 10 constituting the band clamp 1b is unfolded. A schematic perspective view is shown, and FIG. 7(b) shows a front view of the band clamp 1b in the same state. FIG. 8 shows an explanatory view of the state of use of the band clamp 1b of the third embodiment, specifically, a front view of the band clamp 1b of the third embodiment in which the band portion 10 is wound around the wire harness 100 and fixed. indicates

As shown in FIGS. 7 and 8, the band clamp 1b is provided with a plurality of, specifically five, integral projections 60 having a substantially S-shape at predetermined intervals in the longitudinal direction L. ing. In the band clamp 1b, the branch wire 120 is arranged between the adjacent integral convex portions 60, and the band portion 10 is wound around the outer periphery of the main wire 110 and fixed with the buckle portion 20.例文帳に追加

Specifically, the integral protrusion 60 includes two first protrusions 40 extending in a first cross direction X1 that intersects the longitudinal direction L of the band portion 10, and two first protrusions 40 extending in the first cross direction. and a second convex portion 50a extending in a second crossing direction X2 crossing X1.

Like the band clamp 1a, the first protrusion 40 is composed of a first protrusion 41 on one side and a first first protrusion 42 on the other side. are provided alternately in the longitudinal direction L at predetermined intervals.

The second convex portion 50a extends along the longitudinal direction L so as to connect the end portion of the first convex portion 41 on the intermediate portion side to the end portion on the intermediate portion side of the first convex portion 42 on the other side. are set up. That is, the first convex portion 40 and the second convex portion 50a connect the first convex portion 41 on the one side and the first convex portion 42 on the other side, which are provided at a predetermined interval in the longitudinal direction L, with the second convex portion 50a. A portion 50a is integrally formed.

In other words, in the spacing portion 43 that is the space between the one-side first convex portion 41 and the other-side first convex portion 42, the one-side first convex portion 41 and the other-side first convex portion 41 forming the integrated convex portion 60 The second protrusions 50a are arranged in the first spacing section 44 between the protrusions 42, and the second protrusions 50a are arranged in the second spacing section 45 between the adjacent integrated protrusions 60. not The branch wire 120 can be arranged in the second spacing portion 45 where the second convex portion 50a is not arranged.

With such a band clamp 1a, when the band portion 10 is wound around the wire harness 100, as shown in FIG. and fixed with the buckle part 20. As a result, the first protrusions 40 are arranged on both sides in the circumferential direction C of the branch line 120 . Also, in FIG. 8, the branch wire 120 is arranged in the second spacing portion 45 closest to the distal end side, but the branch wire 120 can be arranged in the second spacing portion 45 corresponding to the position where the branch wire 120 should be placed. I'm trying

The integral projections 60 (the three integral projections 60 on the base side in FIG. 8) other than the integral projection 60 having the first projection 40 that abuts the branch wire 120 are connected to the band portion 10 by the trunk line 110. When it is wrapped around the outer circumference of the main line 110, it bites into the main line 110.例文帳に追加

According to the band clamp 1b configured in this manner, the first protrusions 40 arranged on both sides of the branch wire 120 in the circumferential direction C suppress the positional deviation of the branch wire 120 in the circumferential direction C, while the branch wire 120 is The integral projections 60 other than the integral projections 60 used for suppressing positional deviation can be made to bite into the trunk line 110 .

As a result, it is possible to suppress the displacement of the main line 110 in its axial direction. In particular, the integral convex portion 60 includes a second convex portion 50a extending in the second cross direction X2 perpendicular to the axial direction of the main line 110, and the second convex portion 50a effectively suppresses positional displacement in the axial direction. works.

In addition, since the first convex portion 40 and the second convex portion 50a are integrally formed, the first convex portion 40 is reinforced by the second convex portion 50a, and the first convex portion 40 abuts on the branch wire 120. Even if a force in the circumferential direction C outer side acts on the first convex portion 40, deformation in the circumferential direction C outer side can be suppressed. As a result, the movement of the branch wire 120 in the circumferential direction C can be further restricted by the first convex portion 40, and the displacement of the first convex portion 40 in the circumferential direction C can be further suppressed.

Since the second convex portion 50a is arranged only in the first interval portion 44, which is one of the interval portions 43 adjacent to each other in the longitudinal direction L, the second convex portion 50a is provided to reinforce the first convex portion 40. The first spacing portions 44 for arranging the branch wires 120 and the second spacing portions 45 for arranging the branch wires 120 are provided alternately. This allows efficient use of space.

Further, since the second spacing portion 45 in which the second convex portion 50a is not arranged can be easily deformed, the main line 110 of the band portion 10 can be deformed even though it has the first convex portion 40 and the second convex portion 50a. It is possible to easily perform the winding work to.

Next, a band clamp 1c of a fourth embodiment shown in FIGS. 9 and 10 will be described.
FIG. 9 shows an explanatory view of the band clamp 1c of the fourth embodiment. Specifically, FIG. 9(a) shows the inner surface side of the band clamp 1c in a state in which the band portion 10 constituting the band clamp 1c is unfolded. A schematic perspective view is shown, and FIG. 9(b) shows a front view of the band clamp 1c in the same state. FIG. 10 shows an explanatory view of the state of use of the band clamp 1c of the fourth embodiment, specifically, a front view of the band clamp 1c of the fourth embodiment in which the band portion 10 is wound around the wire harness 100 and fixed. indicates

As shown in FIG. 9(a), the band clamp 1c is arranged such that integral protrusions 60a each having a substantially T-shape are arranged in the longitudinal direction L while being alternately turned upside down. Specifically, the integrated convex portion 60a is composed of the first convex portion 40 and the second convex portion 50b extending in the second cross direction X2. The second projecting portion 50b is formed integrally with the first projecting portion 40, and is arranged across the first projecting portion 40 in the second cross direction X2. That is, the second protrusions 50b are formed to extend from the ends of the first protrusions 40 on the intermediate portion side toward both sides in the second cross direction X2.

Further, as shown in FIG. 9B, the second convex portion 50b is formed such that the orthogonal cross section perpendicular to the first cross direction X1 is tapered toward the projecting direction. Specifically, the second convex portion 50b is formed so as to form a curved surface 51 concave inward from the first convex portion 40 to the outer side in the second cross direction X2 when viewed from the front. In other words, the slope of the curved surface 51 is configured to become gentle toward the outer side in the second intersecting direction X2. The curved surface 51 has a curvature larger than that of the branch wire 120 , and is provided so that the branch wire 120 arranged in the interval portion 43 is in contact with the inner surface of the band portion 10 .

In the band clamp 1c having such a second convex portion 50b, when the band portion 10 is wound around the wire harness 100, the branch wire 120 is arranged in the space portion 43 between the adjacent first convex portions 40. Then, the band portion 10 is wound around the outer periphery of the main line 110 and fixed with the buckle portion 20 . As a result, as shown in FIG. 10, the curved surface 51 receives the peripheral surface of the branch wire 120, and the first protrusions 40 are arranged on both sides of the branch wire 120 in the peripheral direction C, and the band clamp 1c is attached to the band clamp 1c. A wire harness 100 is held.

According to the band clamp 1c configured in this way, the branch wire 120 can be placed between the second protrusions 50b while the second protrusions 50b straddle the gaps 43 where the branch wires 120 are arranged. can be placed. Thereby, the branch wire 120 can be arranged in each space portion 43, and the arrangement of the branch wire 120 can be flexibly handled as compared with the band clamp 1b.

In addition, since the second protrusions 50b are tapered, even when the branch line 120 is arranged between the second protrusions 50b, the amount of the second protrusions 50b biting into the trunk line 110 can be suppressed. can reduce the load on In particular, since the curved surface 51 of the second convex portion 50b is concave inward, the curved surface 51 can receive the peripheral surface of the branch line 120, and the load on the trunk line 110 can be further suppressed.

Furthermore, when the band portion 10 is wrapped around the outer circumference of the trunk wire 110 and fixed with the buckle portion 20 in a state where the branch wire 120 is arranged in the space portion 43, the peripheral surface of the branch wire 120 is received by the curved surface 51, and the branch wire is The first protrusions 40 are arranged on both sides of the circumferential direction C of 120 . Thereby, the positional deviation of the branch wire 120 in the circumferential direction C can be suppressed.

In this manner, the band clamp 1c can more flexibly accommodate the arrangement of the branch wires 120 while suppressing the positional deviation of the branch wires 120 in the circumferential direction C.

In addition, as described above, the second convex portion 50b can suppress the displacement of the main line 110 in the axial direction. By forming the substantially T-shaped integral protrusion 60a, the substantially T-shaped integral protrusion 60a is larger than the area of the region where only the second protrusion 50b contacts the trunk line 110 and the trunk line 110 is deformed. The area of the region where the main line 110 is deformed by coming into contact with is larger. As a result, when the band portion 10 is tightened with the same force, the depth of the convex portion biting into the main line 110 is suppressed. Therefore, the load on the main line 110 can be suppressed.

Next, a band clamp 1d of a fifth embodiment shown in FIGS. 11 to 14 will be described.
11A and 11B are explanatory diagrams of a band clamp 1d of the fifth embodiment, specifically, FIG. 11A is an explanatory diagram of a harness holding portion 2d, and FIG. 11B is an explanatory diagram of a vehicle attachment portion 3a. Figure shows. 12 and 13 are explanatory diagrams showing a state in which the harness holding portion 2d is connected to the vehicle mounting portion 3d in a predetermined positional relationship.

As shown in FIG. 11, unlike the band clamp 1, the band clamp 1d is composed of a harness holding portion 2d and a vehicle mounting portion 3d which are separately constructed. Specifically, as shown in FIG. 11A, the harness holding portion 2d includes a band portion 10 and a buckle portion 20, and as shown in FIG. An insertion hole 70 is formed through which it can be inserted. In addition, two convex portions 30 are provided on the inner surface of the harness holding portion 2d with a predetermined interval along the longitudinal direction L, and one interval portion 31 is formed.

As shown in FIGS. 12 and 13, the harness holding portion 2d and the vehicle mounting portion 3d fix the band portion 10 with the buckle portion 20 while the band portion 10 is inserted through the insertion hole 70 of the vehicle mounting portion 3d. By doing so, the harness holding portion 2d is connected to the vehicle mounting portion 3d.

With this configuration, the band clamp 1 d can hold the wire harness 100 by arranging the spacing portion 31 in accordance with the position of the branch wire 120 . That is, in the band clamp 1d, the spacing portion 31 is arranged according to the position of the branch wire 120 on the peripheral surface of the main wire 110, and the band portion 10 can be inserted through the insertion hole 70 of the vehicle attachment portion 3d from this arrangement. . By fixing the band portion 10 with the buckle portion 20 in this state, the wire harness 100 can be held by arranging the spacing portions 31 according to the positions of the branch wires 120 on the peripheral surface of the trunk wire 110 . can.

To give a specific example, as shown in FIG. 12(a), when the branch line 120 is arranged at a position immediately adjacent to the vehicle mounting portion 3d on the right side in the drawing, the spacing portion 31 is positioned at a position corresponding to the branch line 120. , the band portion 10 is inserted through the insertion hole 70 from the right side in the drawing and fixed to the buckle portion 20 . Further, as shown in FIG. 12(b), when the branch wire 120 is arranged at a position immediately adjacent to the left side of the vehicle mounting portion 3d in the figure, while arranging the spacing portion 31 at a position corresponding to the branch wire 120, , the band portion 10 is inserted through the insertion hole 70 from the left side in the drawing and fixed to the buckle portion 20 .

13(a) and 13(b), when the branch line 120 is arranged on the side opposite to the vehicle attachment portion 3d, the spacing portion 31 is positioned at a position corresponding to the branch line 120. are arranged, the band portion 10 inserted through the insertion hole 70 is fixed to the buckle portion 20 . In this case, even if the band portion 10 is inserted through the insertion hole 70 from the right side in the drawing as shown in FIG. Even if the wire harness 100 is inserted, the wire harness 100 can be held by arranging the spacing portion 31 according to the position of the branch wire 120 . Therefore, the mounting work can be performed from the side that is easier for the worker to work on.

Thus, according to the band clamp 1d, the harness holding portion 2d can be flexibly arranged according to the arrangement of the branch wire 120, and the spacing portion 31 can be arranged at a position corresponding to the branch wire 120.

Although not shown in the drawing, an identification portion indicating that there is a space portion 31 on the inner surface side is provided at a position corresponding to the space portion 31 on the outer surface of the harness holding portion 2d. Even when working while looking at the outer surface side, the position of the spacing portion 31 can be identified. The configuration of the identification portion is not particularly limited, and examples thereof include marks such as characters and symbols, cutouts, and the like.

Furthermore, an example of a method for manufacturing the wire harness 100 using such a band clamp 1d will be described with reference to FIG. Briefly, it is a method for manufacturing a wire harness 100 configured along a wiring route defined in a wiring board 300, and in the wiring board 300 in which the wiring route of the wire harness 100 is defined, the wiring route Attach the band clamp 1d to a predetermined location on the top. The trunk line 110 and the branch line 120 are placed along the band clamp 1d, and the trunk line 110 and the branch line 120 are held by the band clamp 1d.

Here, FIG. 14 shows an explanatory diagram of the state of use of the band clamp 1d of the fifth embodiment, and more specifically, an explanatory diagram showing the process of attaching the band clamp 1d of the fifth embodiment to the wire harness 100. .

First, as shown in FIG. 14( a ), the vehicle attachment portion 3 d is attached to a predetermined location on the wiring board 300 . Subsequently, as shown in FIG. 14(b), the trunk line 110 is wired to the vehicle attachment portion 3d, and the branch line 120 is wired to a predetermined position with respect to the cross section of the trunk line 110 with respect to the branch line 120. .

Then, as shown in FIG. 14(c), the spacing portion 31 is arranged at the position of the routed trunk line 110, and the band portion 10 is inserted through the insertion hole 70 of the vehicle mounting portion 3d. Further, as shown in FIG. 14(d), the band portion 10 is fixed by the buckle portion 20 while the trunk line 110 is tightened by the band portion 10, and the harness holding portion 2d is connected to the vehicle mounting portion 3d.

As a result, the routed trunk line 110 and branch line 120 can be held by the harness holding portion 2d and fixed to the vehicle mounting portion 3d.

The wire harness 100 can be manufactured by performing this work at each location on the routing board 300 . By such a method, it is possible to efficiently manufacture the wire harness 100 in which the trunk line 110 is prevented from coming off and being displaced by the band clamp 1d.

The present invention is not limited to the configurations of the above-described embodiments, and many embodiments can be obtained.

For example, the distance between the convex portion 30, the first convex portion 40 (the first convex portion 41 on one side and the first convex portion 42 on the other side), the second convex portions 50, 50a, and 50b, and the height of the protrusion, which have been particularly described in the above description. The height (or maximum projecting height), shape, number, range provided on the band portion 10, extension length/position, crossing direction, etc. are only examples. Therefore, without being limited to this, any change may be made as appropriate as long as it is possible to prevent the branch line 120 from coming off or being misaligned, and the trunk line 110 from being misaligned.

For example, the distance between the projections 30 and the first projections 40 is not limited to being larger than or substantially equal to the diameter of the branch wire 120 . For example, if the distance between the projections 30 and the first projections 40 is set to be smaller than the diameter of the branch wire 120, a portion of the branch wire 120 may be spaced between the projections 30 and the first projections 40 instead of the entire width of the branch wire 120. The positional deviation of the branch wire 120 may be suppressed by receiving it in between.

The protrusion heights of the protrusions 30 and the first protrusions 40 may also exceed the diameter of the branch wire 120 . Further, if the distance between the projections 30 and the first projections 40 is smaller than the diameter of the branch wire 120 , the branch wire 120 may be positioned at the harness holding portion 2 depending on the projection height and distance of the projections 30 and the first projections 40 . In some cases, it contacts only the convex portion 30 or the first convex portion 40 without contacting the inner surface of the .

In this case, the convex portion 30 and the first convex portion 40 may strongly bite into the branch wire 120 and apply a strong load. Therefore, when the branch wire 120 is received in the spacing portion 31 or the spacing portion 43, the protrusion height of the protrusion 30 or the first protrusion 40 is adjusted so that the branch wire 120 contacts the inner surface of the harness holding portion 2. It may be determined according to For example, the larger the distance, the larger the projection height, and the smaller the distance, the smaller the projection height.

Moreover, the shape of the convex portion 30 and the first convex portion 40 is not limited to a rectangular parallelepiped shape or a tapered shape, and may be changed as appropriate. The tapered shape is also not limited to the specific shape described above, and is not particularly limited as long as it tapers in the projecting direction, such as a triangular shape. Moreover, the load on the main line 110 and the branch line 120 may be suppressed by rounding the corner portions.

The number of protrusions 30, first protrusions 40, second protrusions 50, 50a, and 50b may be any number as long as the number of protrusions 30 and first protrusions 40 is two or more. When the projections 50, 50a, 50b are provided, the number thereof should be one or more.

The range on the band portion 10 where the convex portion 30, the first convex portion 40, the second convex portions 50, 50a, and 50b are provided does not have to be the predetermined range on the base side, and is provided over the predetermined range on the tip side. good too. Also, regarding the length and position of these extensions, for example, the convex portion 30 extends over the entire length of the band portion 10 in the cross direction X, and the first convex portion 40 extends at either end of the band portion 10 in the cross direction X. to the intermediate portion of the band portion 10, but the present invention is not limited to the above-described configuration and can be changed as appropriate. Furthermore, even when the first convex portion 40 and the second convex portions 50, 50a, 50b are integrally formed, the mode of integral formation is not limited to the above-described one, and can be changed as appropriate.

In the above description, the intersecting direction X and the first intersecting direction X1 are the directions perpendicular to the longitudinal direction L, and the second intersecting direction X2 is the direction parallel to the longitudinal direction L. may be a direction intersecting 0 to 90° with respect to . Also, the first crossing direction X1 and the second crossing direction X2 are not limited to being perpendicular to each other as described above, and may be crossed at a desired angle other than 0° and 90°.

For example, FIG. 15 shows a specific example in which the shape, extension length/position, crossing direction, etc. of the protrusion 30, the first protrusion 40, and the second protrusions 50, 50a, and 50b are different from those described above. Description will be made with reference to FIGS.

For example, as shown in FIG. 15, instead of the convex portion 30, a convex portion 30a tapered toward the projecting direction in a front view may be used (an example of shape change). As a result, it is possible to suppress the protrusion 30 a from biting into the branch wire 120 while suppressing the positional deviation of the branch wire 120 .

Further, as shown in FIG. 16, the extension length and position of the first projection 40 are changed to form a first projection 40a extending over the entire length of the band portion 10 in the cross direction X, and a second projection 50a. may be integrally formed to form a substantially H shape (an example of changing the extension length and position). As a result, the movement of the branch wire 120 in the circumferential direction C can be restricted over the entire length of the band portion 10 in the cross direction X, and the positional deviation of the branch wire 120 can be further suppressed.

Furthermore, in addition to the first convex portion 40a, as shown in FIG. and the first and second protrusions 40a and 50c may be integrated to form a substantially N-shaped shape (extending length/position, An example of changing the cross direction). As a result, the extension direction (intersecting direction) of the second protrusions 50c is inclined with respect to the direction in which the band portion 10 is bent. It is possible to suppress the influence on the winding work.

Further, as shown in FIG. 18, unlike the band clamp 1b, the one-side first protrusions 41 and the other-side first protrusions 42 are not provided alternately one by one. 41 and two of the other-side first protrusions 42 may be provided alternately. As a result, the second convex portion 50a is formed over the first convex portion 41 on the one side and the first convex portion 42 on the other side.

In this case, the S-shaped convex portion integrally formed by the first convex portion 41 on one side, the first convex portion 42 on the other side, and the second convex portion 50a is formed in the longitudinal direction L while being inverted one by one. will be lined up. By doing so, the movement of the branch wire 120 in the circumferential direction C can be restricted by the one-side first protrusions 41 or the other-side first protrusions 42 facing each other in the longitudinal direction L. As a result, as shown in FIG. 7, the movement of the branch wire 120 in the circumferential direction C is restricted by the one-side first convex portion 41 and the other-side first convex portion 42 that are not opposed to each other. can be further suppressed.

Further, as shown in FIG. 19, in the band clamp 1c, instead of the first convex portion 40, a first convex portion 40b formed to straddle the second convex portion 50b is integrated with the second convex portion 50b. It may be made to exhibit the shape of an approximately cross. Thereby, the movement of the branch wire 120 in the circumferential direction C can be restricted between the first protrusions 40b facing each other in the longitudinal direction L. Therefore, as shown in FIG. 9, compared to the case where the movement of the branch wire 120 in the circumferential direction C is restricted by the one-side first convex portion 41 and the other-side first convex portion 42 that are not opposed to each other, the branch wire 120 can be further suppressed.

In addition, the shapes in which the first convex portion and the second convex portion are integrally formed include, in addition to the shapes exemplified in the above description, a V-shape, a U-shape, an L-shape, and the like. , may adopt various shapes.

Further, in the above description, the second convex portion 50b of the band clamp 1c is configured to have a tapered shape, but this is not necessarily the case. As shown in FIG. 50d. In this case, if the branch wire 120 is arranged between the adjacent second protrusions 50d, the positional deviation of the branch wire 120 in the circumferential direction C can be suppressed by the second protrusions 50d.

Moreover, as shown in FIG. 21 , in the buckle portion 20 , a buckle-side convex portion 80 may be provided on the side where the harness holding portion 2 holds the wire harness 100 . As a result, the branch line 120 can be arranged on the portion of the trunk line 110 facing the buckle portion 20 in such a manner that displacement in the circumferential direction C can be suppressed by the buckle-side convex portion 80 provided on the buckle portion 20 . As a result, the branch line 120 can be arranged more flexibly.

In the above description, the harness holding portion 2d includes the band portion 10 and the buckle portion 20 as the configurations of the harness holding portion 2d and the vehicle mounting portion 3d that are separately configured. A configuration in which an insertion hole 70 through which the band portion 10 can be inserted is formed in the vehicle mounting portion 3d is adopted, and the arrangement of the harness holding portion 2d with respect to the vehicle mounting portion 3d can be adjusted. However, it is not necessarily limited to this configuration, and another configuration that can adjust the arrangement of the harness holding portion 2d with respect to the vehicle mounting portion 3d may be employed, or the harness holding portion 2d and the vehicle mounting portion 3d are simply configured separately. It can be a thing. Also, the insertion hole 70 may be provided with a structure corresponding to the engaging protrusion 22 in the buckle portion 20 so that the band portion 10 can also be fixed by the insertion hole 70 .

In addition, you may combine suitably the another embodiment mentioned above in the possible range.
