Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool for focusing a plurality of electric wires including a specific electric wire, and more specifically,
TECHNICAL FIELD The present invention relates to a wire harness holder capable of positioning and holding a specific electric wire in the center of a cross section of a general electric wire, and particularly to improving workability of the work of inserting the specific electric wire and the general electric wire into respective holding portions of the binding tool.

[0002]

2. Description of the Related Art Conventionally, a wire harness for a vehicle is shown in FIG.
As shown in FIG. 3, the wiring jig 2 is projected and attached at a required position on the upper surface of the wiring harness assembly drawing board 1, and the required electric wire W is inserted into the electric wire insertion portion 2 a of these wiring jigs 2.
In this state, the outer peripheral surface of the electric wire group is wound and bound with a binding material such as the adhesive tape 3 while lifting the electric wire group from the electric wire insertion portion 2a.

In the wire harness W / H formed by bundling a large number of electric wires W as described above, it is necessary to surely prevent noise from entering, or it is absolutely necessary to avoid short circuit with the vehicle body panel. There is a certain electric wire (specific electric wire). For example, when a key is inserted into a vehicle, a power line directly connected to a battery for constantly applying voltage to a lamp system such as a headlamp, an electric door lock system, and a twisted wire for a speaker are included in the specific wire. is there. It is preferable that this type of electric wire is located in the central portion of the cross section in the electric wire group in which the specific electric wire and the electric wires other than the specific electric wire (general electric wire) are bundled, and not in the outer peripheral portion. That is, it is preferable that these wires are located at the center position of the cross section of the wire harness W / H where disconnection is less likely to occur due to interference from the vehicle panel or the like. It is possible to prevent noise from being generated.

On the other hand, the applicant of the present invention has previously described in Japanese Patent Laid-Open No.
In Japanese Patent Laid-Open No. 122135, there is proposed a binding tool capable of binding a specific electric wire in the electric wire group in the center of the cross section of a wire harness and enclosing it with other general electric wires.

[0005]

Problems to be Solved by the Invention FIGS. 8 and 9 (A),
(B) shows an example of a binding tool according to Japanese Patent Laid-Open No. 7-122135. The binding tool 5-1 shown in FIG.
An annular general electric wire holding portion 5A having a notch 5a for inserting an electric wire, and a shaft portion 5 from the inner surface of the general electric wire holding portion 5A.
and a ring-shaped specific electric wire holding portion 5B partially having a notch 5b for inserting a specific electric wire protruding through c, and the small diameter specific electric wire holding portion 5B is provided at the center of the large diameter general electric wire holding portion 5A. While being positioned, a general electric wire accommodation space is provided between the outer peripheral surface of the specific electric wire holding portion 5B and the inner peripheral surface of the general electric wire holding portion 5A.

However, in the above-mentioned binding tool 5-1, the notches 5a and 5b of the general electric wire holding portion 5A and the specific electric wire holding portion 5B are formed.
Since the inlet widths a1 and a2 are narrower than the internal widths b1 and b2, first, the notch 5b needs to be widened by hand to insert the specific electric wire, and then the notch 5a needs to be widened manually to insert the general electric wire. Is difficult to work with. Also, this tying tool 5-
When the wire harness W / H is manufactured using No. 1, it is necessary to tape-wrap the wire group before and after the binding tool 5-1 so that each wire does not come off from each notch 5a, 5b. However, when this tape winding is performed, there is a risk that the electric wires will be offset in the general electric wire holding portion 5A and the specific electric wire holding portion 5B, and the tape winding operation itself will be difficult.

Furthermore, in the binding tool 5-2 shown in FIG. 9 (A), the upper portion 5e of the general electric wire holding portion 5A is divided and is openably and closably connected by the hinge portion 5f, and the notch of the general electric wire holding portion 5A is formed. 5a is widened, but notch 5 of specific electric wire holding portion 5B
Since the width of b is narrow, it is necessary to push the notches 5a and 5b by hand to insert the electric wire, as in the case of the binding tool 5-1 shown in FIG. is there.
Further, in this binding jig, when the hinge 5f is bent to close the lid, the general electric wire may be caught.

Furthermore, the tying member 5-shown in FIG.
In 3, the specific electric wire W2 is inserted from the elastic slit portion 5g into the specific electric wire holding portion 5B to close the specific electric wire holding portion 5B, and then the general electric wire holding portion 5A is inserted while passing through the general electric wire W1. The two-step work of closing the electric wire holding portion 5A is required, and the work of inserting the electric wires W1 and W2 is difficult.

The present invention has been made in order to solve the problem in the conventional wire harness bundling jig as described above, in which the important electric wires are arranged in the central portion of the wire harness and the general electric wires are arranged around them. It is an object of the present invention to provide a wire harness binding jig that can be bound in a state where the wire harness is bound and can be bound efficiently.
