Description

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

A long wire harness that electrically connects electrical devices mounted on a vehicle is a two-dimensional or three-dimensionally complicated wiring route that combines straight portions and curved portions. It is wired and attached to the vehicle body panel via a band clamp, for example as disclosed in US Pat.

The band clamp disclosed in Patent Document 1 will be described in detail. The band clamp can hold the wire harness by winding a strip-shaped band around the wire harness and inserting the tip of the band into a buckle connected to the base of the band and tightening the buckle. Then, the wire harness can be fixed to the vehicle body panel by inserting and fixing the fixing member (anchor) of the band clamp holding the wire harness into the through hole of the vehicle body panel.

2. Description of the Related Art In recent years, with an increase in the number of electric devices mounted on a vehicle, the amount of electric current required for the vehicle has also increased, and accordingly, the wire diameter of the wire harness has also increased. On the other hand, by making the wire harness a flat electric wire, it is possible to suppress the enlargement of the wire harness.

However, when the flat electric wire is held by the band clamp described above, a gap is generated between the flat electric wire and the band portion, and the flat electric wire cannot be firmly held. Further, when the band portion is tightly tightened to firmly hold the flat electric wire, the flat electric wire is curved in the plate thickness direction along the arc-shaped band portion. Therefore, there is a problem that the advantage of the flat electric wire cannot be obtained.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a band clamp and a flat electric wire with a band clamp capable of firmly holding a flat electric wire while maintaining the shape of the flat electric wire.

The present invention includes a vehicle body fixing portion fixed to a vehicle body panel of a vehicle, a band portion holding the flat electric wire along the outer surface of the flat electric wire routed to the vehicle, at least a part of the band portion and the A connecting portion that connects with a vehicle body fixing portion, and a band locking portion that locks and fixes the band portion that holds the flat electric wire, wherein the band locking portion extends at least in the width direction of the held flat electric wire. A band clamp located on one side.

Further, the present invention includes a flat electric wire routed in a vehicle, a vehicle body fixing portion fixed to a vehicle body panel of the vehicle, a band portion holding the flat electric wire along an outer surface, and at least a part of the band portion and the vehicle body fixing portion. and a band clamp for locking and fixing the band portion in a state where the flat electric wire is held, wherein the band locking portion holds A flat electric wire with a band clamp is arranged on at least one side in the width direction of the flat electric wire.

The vehicle body fixing portion includes, for example, an anchor that is inserted into an insertion hole provided in the vehicle body panel and fixed, a stud bolt that is fixed by inserting a bolt fixed to the vehicle body panel, and the like.
The above-mentioned at least a part of the band portion includes a case where one band portion is connected to the connecting portion, or a plurality of band portions at least partially connected to the connecting portion. For example, when it is composed of one band portion connected to the connecting portion by being inserted into the connecting portion, or when it is composed of a plurality of band portions connected to the connecting portion, It includes a case where it is composed of a band portion connected to a connecting portion and a band portion not connected to the connecting portion.

The band engaging 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 described above refers to the longitudinal direction in an orthogonal cross section perpendicular to the longitudinal direction of the flat electric wire. That is, the band engaging portion is arranged on at least one of the longitudinally opposite sides of the flat electric wire in the orthogonal cross section.

The flat electric wire may be held by the band portion such that the width direction is parallel to the vehicle body panel, or held by the band portion so that the width direction is upright with respect to the vehicle body panel. Including cases.
Along the outer surface of the flat electric wire described above means along at least a part of the outer surface of the flat electric wire along the width direction. That is, it includes the case where it is along the surface along the width direction in the orthogonal cross section of the flat electric wire, or the case where it is not along the surface.

According to this invention, by locking and fixing the band portion with the band locking portion, the flat electric wire can be held so that the band portion follows the outer surface of the flat electric wire. It is possible to prevent the flat electric wire from bending in the plate thickness direction. As a result, the shape of the flat electric wire can be maintained, and the flat electric wire can be fixed at a predetermined position in the vehicle without applying a load to the flat electric wire. Therefore, it is possible to obtain the effect of the flat electric wire that the height of the flat electric wire in the plate thickness direction is suppressed and the heat dissipation is improved. In addition, maintaining the shape of a flat electric wire here means preventing bending to such an extent that the flat electric wire's effect, such as heat dissipation, is produced.

As an aspect of the present invention, the band portion may hold the flat electric wire 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. Therefore, it is possible to effectively utilize the vehicle space around the routed flat electric wires.

Further, as an aspect of the present invention, the band portion may have a bending promoting portion that promotes bending on at least the other side in the width direction.
The above-mentioned at least the other side in the width direction means a case in which the other side in the width direction and one side, that is, a side on which the band engaging portion is arranged also have a bending promoting portion, or a case in which the entire band portion has a bending promoting portion. Including the case of having a song promotion part.

According to this invention, at least on the other side in the width direction, the band portion can be bent along the contour of the other side in the width direction of the flat electric wire. That is, since the band portion can be laid along a part of the surface along the transverse direction in the orthogonal cross section of the flat electric wire, it is possible to suppress the formation of a gap between the band portion and the flat electric wire. can be securely held by the band.

Further, when the bending facilitating portion is provided not only on the other side in the width direction but also on one side, the band portion can be bent to match the outer surface of the flat electric wire also on the one side in the width direction of the band portion. Therefore, since the band portion can be bent along the outer surface of the flat electric wire in both width directions, the flat electric wire can be held by the band portion more reliably.

Further, as a mode of the present invention, the bending promoting portion may be configured by a groove extending along the longitudinal direction of the flat electric wire on the outer surface of the band portion.
The song promoting part may be singular or plural. Further, when there are a plurality of the bending-enhancing portions, the depth of the grooves of the bending-enhancing portions may be uniform along the longitudinal direction of the band, including the case where they are arranged at equal intervals or uneven intervals. Including case or non-uniform case.

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. In addition, when a large number of bending promoting portions are arranged along the longitudinal direction of the band portion, even for various flat electric wires having different plate thicknesses and lengths in the width direction, along the outer surface of the flat electric wire, can bend the band.

Further, as a mode of the present invention, the band portion is provided with a locking piece, the band locking portion has an insertion hole through which the band portion is inserted, and the locking piece in the band portion is inserted into the insertion hole. and a to-be-locked portion that locks may be provided.

According to the present invention, by simply pulling at least the band portion inserted through the insertion hole to one side in the width direction, the band locking portion is locked and fixed to the band portion while preventing unintended loosening of the tightening of the band portion on the flat electric wire. can. Therefore, the operation of holding the flat electric wire in the band portion can be performed efficiently.

Further, as an aspect of the present invention, the locking piece may be provided on the outer surface of the band portion that holds the flat electric wire.
The outer surface of the band portion mentioned above refers to a surface opposite to a surface facing the flat electric wire in a state in which the flat electric wire is held by the band portion.

According to this invention, the band locking portion can be locked and fixed to the band portion more reliably.
More specifically, since the band portion is bent inward in the plate thickness direction of the flat electric wire and inserted into the insertion hole, the band portion receives a reaction force directed outward in the plate thickness direction inside the insertion hole. works. Due to this reaction force, the inner surface side of the band engaging portion in the plate thickness direction and the outer surface of the band portion are reliably brought into contact with each other, so that the engaging piece and the engaged portion can be more reliably engaged.

Further, as an aspect of the present invention, the band engaging portion is configured separately from the band portion, and the insertion hole in the band engaging portion is formed by two of the band portions protruding at least on one side in the width direction. may be inserted through each end.

The above-mentioned two ends on at least one side in the width direction means that both ends of one band portion connected to the connecting portion protrude to one side in the width direction, or are connected to the connecting portion. When the ends of two band portions connected to each other, or the ends of one band portion connected to the connecting portion and one band portion not connected to the connecting portion are projected to one side in the width direction and so on.
The band portion and the band engaging portion may be configured such that the band portions inserted through the insertion holes are engaged one by one, or two band portions are inserted through the insertion holes, respectively, so that the two band portions are engaged with the band. It includes a configuration that locks and fixes together with the stop portion.

According to this invention, by inserting the two end portions protruding to one side in the width direction into the respective insertion holes and pulling them to one side in the width direction, the band portions arranged in the plate thickness direction of the flat electric wire are secured. The band portion and the band locking portion can be collectively locked and fixed while holding the flat electric wire in the flat wire. Therefore, the operation of holding the flat electric wire in the band portion can be efficiently performed.

Further, since the band engaging portion is separate from the band portion, the band engaging portion can be arranged at the central portion of the flat electric wire in the plate thickness direction regardless of the plate thickness of the flat electric wire. Therefore, it is possible to more reliably prevent bending of the flat electric wire due to tightening of the flat electric wire by the band portion.

Further, as an aspect of the present invention, the locking pieces may be arranged on the same side of the locking pieces at the two ends inside the band locking portion.
The phrase "the locking pieces at the two ends may be arranged on the same side" means that the locking pieces at the two ends are both arranged inside or outside the inside of the band locking portion. In other words, when the locking piece is arranged in a plane-symmetrical position with respect to the locking piece of the other band portion, or when the locking piece and the locking piece of the other band portion are arranged on the band portion It includes the case where it is deviated along the longitudinal direction of the

According to the present invention, the band engaging portion can be used even if it is reversed in the plate thickness direction of the flat electric wire, so that the efficiency of the assembly work for assembling the band engaging portion to the band portion can be improved.

Further, as an aspect of the present invention, the band portion may be provided with a protrusion projecting from an inner surface toward the flat electric wire in a state in which the flat electric wire is held.
According to the present invention, the flat electric wire can be prevented from being displaced in the longitudinal direction and the width direction by the contact of the convex portion with the outer surface of the flat electric wire. In addition, when the protrusion functions as a locking piece, the band is locked and fixed to the band locking portion while preventing the flat wire from being displaced by inserting the band into the insertion hole. can.

In this manner, 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 . A reaction force directed outward in the height direction H is generated in 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 locked to the locked portion 52 more reliably.

Thereby, the flat electric wire 100 can 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 having a substantially flat orthogonal cross section. Therefore, the band portion 30 can hold the flat electric wire 100 while maintaining the shape of the flat electric wire 100 .

A first locking portion 312 and a 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, even if the band engaging portion 50 is reversed in the height direction H, it can be used.

Furthermore, since the band locking portion 50 is configured separately from the first band portion 31 and the second band portion 32, the first band portion 31 and the second band portion 32 are inserted into the insertion holes 51 and 51. By doing so, the band locking portion 50 can be arranged at the central portion in the height direction H of the flat electric wire 100 .

If the band locking portion 50 is arranged with one side in the height direction H, one of the first band portion 31 and the second band portion 32 is excessively curved compared to the other, and the width of the flat electric wire 100 is reduced. A gap is likely to occur between the band portion 30 and the flat electric wire 100 at the end portion in the direction W. Further, when the band portion 30 is tightened more, the flat electric wire 100 may be bent along the height direction H.

However, by arranging the band locking portion 50 at the central portion of the flat electric wire 100 in the height direction H, the first band portion 31 and the second band portion 32 bend substantially the same. As a result, a gap is less likely 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 .

Further, even when the band portion 30 is tightened more, one of the first band portion 31 and the second band portion 32 can be prevented from bending more than the other. The application of an external force in the 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.

Furthermore, since the first band portion 31 is provided with the first bending promoting portion 311 on one side in the width direction W of the flat electric wire 100, the band locking portion 50 is moved to the other side in the width direction W. Thereby, the first band portion 31 can be bent along the outer surface of the flat electric wire 100 on the one end side in the width direction W.

Similarly, since the second band portion 32 is provided with the second bending promoting portion 321 on one side in the width direction W of the flat electric wire 100, the band locking portion 50 is moved to the other side in the width direction W. By doing so, the second band portion 32 can be bent along the outer surface on the one end side in the width direction W of the flat electric wire 100 .

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 held in the thickness direction (height direction H) of the flat electric wire 100. It can be arranged in the central portion, and can prevent the flat electric wire 100 from being subjected to a load in the counter-insertion direction Hu or the insertion direction Hd. Therefore, it is possible to more reliably prevent the flat electric wire 100 from bending in the height direction H while firmly holding the flat electric wire 100 .
