DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tying tool for collecting a plurality of electric wires including a specific electric wire.
The present invention relates to a wire harness holder capable of positioning and holding a specific electric wire at the center of a cross section of a general electric wire, and more particularly to improvement of workability of an operation of inserting a specific electric wire and a general electric wire into each holding portion of a binding device.

[0002]

2. Description of the Related Art Conventionally, a wire harness for a vehicle is shown in FIG.
As shown in the figure, the wiring jigs 2 are protruded and attached at required positions on the upper surface of the wiring harness assembling board 1, and the required electric wires W are inserted into the electric wire insertion portions 2 a of these wiring jigs 2.
In this state, the wire group has been manufactured by winding and binding the outer peripheral surface of the wire group with a bonding material such as an adhesive tape 3 while lifting the wire group from the wire insertion portion 2a.

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

[0004] On the other hand, the present applicant has previously disclosed in
Japanese Patent Application Laid-Open No. -122135 proposes a tying tool capable of tying a specific electric wire in a group of electric wires at a center of a cross section of a wire harness and tying it around another general electric wire.

[0005]

FIG. 8 and FIG. 9 (A),
(B) shows an example of the binding device according to the above-mentioned Japanese Patent Application Laid-Open No. 7-122135. The tying tool 5-1 shown in FIG.
An annular general electric wire holding portion 5A partially having a notch 5a for inserting an electric wire, and a shaft portion 5 from an inner surface of the general electric wire holding portion 5A.
and a circular specific wire holding portion 5B partially having a notch 5b for inserting a specific wire protruding therethrough, and the small-diameter specific wire holding portion 5B is provided at the center of the large-diameter general wire holding portion 5A. In addition, 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 device 5-1, the notches 5a, 5b of the general electric wire holding portion 5A and the specific electric wire holding portion 5B are provided.
Since the widths a1 and a2 of the entrance are smaller than the inner widths b1 and b2, first, the notch 5b is manually expanded to insert a specific electric wire, and then the notch 5a is manually expanded to insert a general electric wire. Work is difficult. In addition, this binding tool 5-
When the wire harness W / H is manufactured by using the wire harness 1, it is necessary to wind and fix the wire group around the tying tool 5-1 so that the wires do not come off from the notches 5 a and 5 b. However, when this tape winding is performed, there is a possibility that the electric wires are offset in the general electric wire holding portion 5A or the specific electric wire holding portion 5B, and the tape winding operation itself is difficult.

Further, in a tying member 5-2 shown in FIG. 9A, the upper portion 5e of the general electric wire holding portion 5A is divided and connected to be openable and closable by a hinge portion 5f. 5a is expanded, but the notch 5 of the specific electric wire holding portion 5B is provided.
Since the width of b is narrow, as in the case of the tying tool 5-1 shown in FIG. 8 described above, it is necessary to push the notches 5a and 5b by hand to insert the electric wires, which makes the operation difficult. is there.
Further, in this binding jig, when the hinge 5f is bent to close the lid, there is a possibility that a general electric wire may be caught.

Further, a tying member 5 shown in FIG.
In 3, after inserting the specific electric wire W2 into the specific electric wire holding portion 5B from the elastic slit portion 5g and closing the specific electric wire holding portion 5B, the general electric wire holding portion 5A is further inserted while being passed through the general electric wire W1. A two-stage operation of closing the electric wire holding portion 5A is required, and it is difficult to insert the electric wires W1 and W2.
