DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire holder for binding and holding a solid transmission line such as an electric wire or an optical fiber and a hollow wire such as a tube in combination.

[0002]

2. Description of the Related Art In recent years, transmission wires such as a wire bundle and an optical fiber bundle for vehicles, and a bundle of piping for liquid or compressed air (air) are bound and fixed to a desired mounting surface. Holders such as band clips are widely used.
Especially in wire harnesses installed in vehicles,
BACKGROUND ART Band clips are often used to fix branch lines routed to each electric or electronic component with several wires, including a trunk line portion where a large amount of wires are converged.

[0003] On the other hand, as a wire rod routed in a vehicle,
In addition to the above-mentioned wire harness, for example, a tube pipe having a hollow structure for sending a window washer liquid from a washer tank to a washer nozzle is provided. These tube pipes are usually attached to the wire harness along the wiring harness wiring route,
Alternatively, the attachment is performed so as to be bound together with the wire harness. In particular, in the case of binding together with the wire harness, it can be carried out in the manufacturing process of the wire harness, so that there is an advantage that the number of work steps can be reduced. That is, as shown in FIG. 4A, after the electric wire 11 is put into the U jig 13 installed on a predetermined wiring route on the wiring harness assembly drawing board, the tube piping 12 such as a washer tube is put in, As shown in FIG. 4B, binding and fixing are performed by the band clip 1 '. Here, the order in which the electric wires 11 and the tube piping 12 are put into the U jig 13 may be such that the tube piping 12 is first.

[0004]

As described above, FIG.
A wire harness in which the tube pipe 12 is bound and fixed together with the electric wires 11 is obtained by the band clip 1 ′ and the binding tape 14 as shown in (a), but tens to hundreds of the electric wires 11 are securely bound. Therefore, it is necessary to increase the tightening force of the band clip 2 by the band clip 1. For this reason, the tube portion 12 tied to the band clip 1 ′ together with the electric wire 11 also has the band portion 2.
The pressing force accompanying the tightening acts on the band portion 2. In particular, since the pressing force is in contact with the inner peripheral surface of the band portion 2 on which the tightening force is directly applied, the cross-sectional shape is deformed as shown in FIG. The cross-sectional area (hollow area) of the hollow portion is reduced.
In general, the tube pipe 12 for a window washer is formed by connecting a plurality of pipes through joints everywhere.
There was a problem that the internal pressure was increased and liquid leaked from the joint.

[0005] Such a problem is particularly caused by a hollow wire (tube tube or the like) having a hollow structure which is relatively easily deformed by an external pressure.
Because it is sandwiched between a solid structure wire (such as an electric wire or an optical fiber) whose hand shape is not easily deformed by external pressure and the band of the hand clip, the tightening force of the band directly acts on the wire having a hollow structure. However, for example, when the number of electric wires is large, since the tube pipe is divided between the electric wires and penetrated, the reduction in the hollow area due to the deformation can be suppressed to a small value. On the other hand, when the tube pipe cannot be pierced even if it is divided between the wires according to the tightening of the band, for example, when the number of wires is small or the outer diameter of the wires is large, the hollow area is small. The decrease has been found to be significant.

An object of the present invention is to solve such a problem and to provide a wire holder which can suppress the collapse of the tube pipe due to the tightening force when the tube pipe is bound together with the electric wire. I have.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a band-shaped band portion is inserted into a band locking portion and a wire is bound by an inner peripheral surface of the band portion. In the holder for holding a wire, the second wire having a hollow structure, which is bound and held on the inner peripheral surface of the band portion together with the first wire having a solid structure, is connected to the inner periphery related to the binding of the band portion. It is characterized in that a protection portion for holding against the pressing force in the direction is provided.

[0008] With such a configuration, the protection portion holds the tube pipe (second wire) so as not to deform against the pressing force generated due to the tightening of the band portion.
The clamping force of the band portion does not directly act on the tube piping sandwiched between the band portion and the electric wire (first wire material), the collapse of the tube piping is suppressed, and the liquid leakage due to the reduction of the hollow area. Can be prevented.

Further, since the tube pipe can be attached to the band clip fixed to the clip jig provided on the wire harness assembly drawing board in advance and bound together with the electric wire, the tube pipe arranged in the electric wire bundle can be attached. The binding position can be kept constant, and a wire harness having uniform quality can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a first embodiment of a band clip according to claim 1 of the present invention. In FIG. 1A, a band clip 1 has a band portion 2 for converging a wire such as an electric wire, the band portion 2 is wound around the wire, and the inserted band portion 2 is locked and fixed at an arbitrary tightening position. Locking portion (band locking portion) 3, a clip portion 4 for engaging and fixing the bound wire at a predetermined position on a vehicle body or the like, and a locking portion 2 on the inner peripheral side of a binding circle formed by the band portion 2. It has a pipe holding part (protection part) 5 that projects from the lower part and holds a hollow wire (second wire) such as a tube pipe. Here, the pipe holding part 5 is formed to have a curved surface on the inner surface side corresponding to the shape of the tube pipe to be held in advance. Further, the member constituting the pipe holding portion 5 is formed so as to have sufficient rigidity so as not to be deformed by at least a pressing force generated by tightening the band portion 2 at the time of binding the wires.

FIG. 1B shows a state in which wires are bound by the band clip 1 shown in FIG. As shown in the drawing, a plurality of electric wires (first wires) 11 and a tube pipe 12 such as a washer tube are bound by a binding circle formed by the band portion 2. Tube piping 12
Is held by a pipe holding section 5 provided below the lock section 3 of the band clip 1 and has rigidity.
Accordingly, even when the band portion 2 is fastened, the band portion 2 is bound in the wire 11 even if the wire portion 11 is inserted into the wire 11.

As described above, the tube pipe 12 bound together with the electric wire 11 is held by the pipe holding section 5 having rigidity, the hollow shape thereof is protected, and the tube pipe 12 is held as the band section 2 is tightened. Since the wire 11 is inserted into the wire 11 together with the pipe holding part 5, the pressing force generated between the wire 11 and the band 2 due to the tightening of the band 2 is not directly applied to the tube 12. Therefore, it is possible to suppress the state where the cross-sectional shape of the tube pipe 12 is crushed and the hollow area is reduced, and it is possible to prevent liquid leakage due to an increase in the internal pressure of the tube pipe 12.

Next, a wire harness manufacturing process using the band clip 1 shown in FIG. 1A will be described with reference to FIG. First, as shown in FIG. 2A, the band clip 1 is previously fixed to a clip jig 15 installed together with the U jig 13 of the wire harness assembly drawing board, and a tube is attached to the pipe holding portion 5 of the band clip 1. Holds the pipe 12. Next, the electric wire 1 is set on the U jig 13 by a predetermined wiring route.
2 is inserted, the clip jig 15 is moved to a predetermined mounting position as shown in FIG.
2 and the electric wire 11 are bound.

According to such a wire harness assembling step, the tube pipe 12 is held in advance by the pipe holder 5 of the band clip 1 fixed to the clip jig 15 provided on the wire harness assembly drawing board, 11 can be bound together, so that the binding position of the tube pipes 12 arranged in the bundle of electric wires 11 can always be constant. Therefore, it can be arranged at an arbitrary binding position where deformation of the tube pipe 12 due to bending of the wire harness or the like can be reduced, and a uniform and high-quality wire harness with a tube pipe can be provided.

FIG. 3 shows another embodiment of the wire binding device according to the first aspect of the present invention. In the band clip 1 shown in FIG. 3A, the pipe mounting direction of the pipe holding section 5 a protruding from the lower part of the lock section 3 is the same as the direction in which the tightening force generated by the band section 2 is generated (inner circumferential direction). Are characterized by being provided differently. for that reason,
According to the pipe holding portion 5a having such a configuration, the tube pipe 12 can be held and protected in the same manner as in the above-described embodiment, and a member is interposed between the tube pipe 12 and the electric wire 11 to be opened in the inner circumferential direction. Since the tube pipe 12 does not directly contact the electric wire 11,
The pressing force generated by the tightening of the band portion 2 does not act.

In the band clip 1 shown in FIG. 3 (b), as in the embodiment shown in FIG. 3 (a), the pipe mounting direction of the pipe holding section 5b provided below the lock section 3 is It is characterized by being provided so as to be different from the inner circumferential direction and being provided with a plurality of curved surface shapes so as to hold a plurality of tube pipes 12. Here, the inner diameters of the plurality of curved surface shapes may be the same, or may have different inner diameters as shown in the drawing.

According to the pipe holder 5b having such a configuration, the tube pipe 1 is formed into a curved shape corresponding to the number or the outer diameter of the tube pipes 12 bound together with the electric wires 11.
2 can be held, so that the tube pipe 12 can be appropriately protected against the pressing force generated due to the binding of the band portion 2. Further, in the band clip 1 shown in FIG. 3C, the pipe holding portion 5c is formed integrally with the lower portion of the lock portion 3, and the band portion extends from below the pipe holding portion 5c (the lower end of the lock portion 3). It has a characteristic shape.

According to the pipe holder 5c having such a configuration, the tube pipe 12 bound together with the electric wire 11 is
Since the band can be arranged in a bound state in which the band is not divided into the band formed by the band 2, that is, substantially outside the band formed by the band 2, the band is generated with the band 2 tightened. The tube can appropriately hold and protect the gap 12 without being affected by the pressing force.

In the above-described embodiment, a configuration is shown in which the pipe holding portion for protecting and holding the tube pipe is provided below the lock portion. However, the present invention is not limited to this. If provided on the inner peripheral side of the binding circle formed by the band portion, it may be provided on the band portion.
In the above embodiment, a washer tube is shown as a wire having a hollow structure. However, the present invention is not limited to this, and may be an air pipe for sending compressed air (air) or the like. It can be applied favorably to a wire rod having a hollow structure that has higher deformability than a wire rod of an actual structure and that may possibly hinder the lubrication of the object to be delivered due to deformation of the hollow part. Needless to say.

[0020]

As described above, according to the band clip according to the first aspect of the present invention, the protection portion holds the tube pipe so as not to deform the tube pipe against the pressing force caused by the tightening of the band portion. The clamping force of the band portion does not directly act on the tube piping sandwiched between the band portion and the electric wire, thereby suppressing the collapse of the tube piping and preventing the liquid leakage due to the reduction of the hollow area. it can.

In addition, since the tube pipe can be attached to the band clip fixed to the clip jig provided on the wire harness assembly drawing board in advance and bound together with the electric wire, the tube pipe arranged in the electric wire bundle can be attached. The binding position can be kept constant, and a wire harness having uniform quality can be provided.
