Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire arranging jig for concentrating a plurality of electric wires including a specific electric wire and a wire arranging method using the wire arranging jig. This is to enable positioning and holding in the central portion.

[0002]

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

[0003]

In the wire harness formed by bundling a large number of electric wires as described above, it is absolutely necessary to avoid short-circuiting with the vehicle body panel, for example, a battery to which a constant voltage is applied. It is preferable that the power supply line directly connected to the power supply line is located in the central part of the cross section and not in the outer peripheral part of the bundled electric wire group. That is, since a large amount of current is flowing through the power supply line, it is preferable to position the power supply line at a central position where disconnection is less likely to occur due to interference from a vehicle panel or the like.

However, in the conventional wire harness bundling method shown in FIG. 11, a large number of electric wires W are randomly inserted from the upper end opening into the electric wire insertion portion 2a of the wiring jig 2, and the above-mentioned power source is used. No means for positioning and holding the specific electric wire, which is desired to be positioned at the center position of the wire or the like, at the center of the electric wire group is provided. When laying wires, it is only necessary for the worker to bundle them while positioning the specific wires in the center, but if you do not know which wire is the specific wire, you cannot position these specific wires in the center. Absent. On the other hand, when recognizing the specific electric wires and positioning the specific electric wires at the central position when binding them with the tape 3, since the number of the specific electric wires is usually plural, while positioning the plural specific electric wires at the center. It is not easy to unite.

Therefore, conventionally, as shown in FIG. 12, a specific electric wire WS which is desired to be positioned at the center of the cross section of the wire harness.
However, the problem that the wire may be located on the outer peripheral portion of the wire harness cannot be reliably solved.

To address the above-mentioned problems, the present applicant has previously proposed that FIG.
As shown in FIG. 3 and FIG. 14, a wiring jig 4 for positioning the specific electric wire W-S at the center of the general electric wire W and binding the wire harness is proposed. (Practical application 5-3917

In this state, as shown in FIG. 13 (B), the half cylinders 4A and 4B are closed and engaged, and the specific electric wire W-S is positioned in the center to form a stratified state. Then, as shown in FIGS. 14A and 14B, the wiring jig 4 is slid along the electric wire W, and the outer periphery of the electric wire W after passing through the wiring jig 4 is covered with an adhesive tape. Partial winding is performed by 3, and the wire harnesses are aligned and layered for bundling.

However, in the wire arranging jig 4, if there is a branch point in the wire W that has been laid, the pair of half cylinders 4A and 4B are disengaged and once removed from the wire W. It is necessary to avoid branch points. further,
After avoiding the branching point, the wiring jig 4 must be attached to the electric wire again, which causes a problem of poor workability.

The present invention has been made in view of the above problems, and in a wire group, a specific wire is located at the center of a cross section of a wire harness and is simply laid in a state surrounded by other general wires.

The electric wire holding portion 12 is integrally formed of a flexible material having elasticity or elasticity such as rubber via the connecting portion 13.

The small-diameter cylindrical portion 10a is set to have an appropriate axial length in consideration of workability, and a slit 10b extending along the axial direction is provided at the upper end of the peripheral edge thereof. A pair of connecting pieces 10c-1 and 10c-2 protruding outward in the radial direction are provided in parallel along both edges of the slit 10b.

One of the connecting pieces 10c is one of the connecting pieces 10c.
-1 is provided with a tongue-shaped outer peripheral wall 10d from its outer end so that the outer peripheral wall 10d surrounds the outer periphery of the small diameter cylindrical portion 10a with a required space (length of the connecting piece 10c). The large-diameter cylindrical portion 10e is formed by bending the other connecting piece 10c-2 in the opposite direction. The space between the outer peripheral surface of the small-diameter cylindrical portion 10a and the inner peripheral surface of the large-diameter cylindrical portion 10e is the general electric wire holding portion 12, and the tip of the general electric wire holding portion 12 and the other connecting piece 10c-2. The gap between the two is used as a general electric wire insertion opening 14.

Next, a wiring process for forming a wire harness using the wiring jig 10 will be described. First, all the electric wires that converge as a wire harness, that is, the specific electric wires WS and the general electric wires W are laid by the wiring jig 2 shown in FIG. 11 attached on the assembly drawing board.

Although the partial winding is performed in the illustrated embodiment, rough winding or half lap winding may be performed instead of partial winding. By the sliding operation of the wiring jig 10, the specific electric wire W-S is inserted through the specific electric wire holding portion 11 of the wiring jig 2 and the general electric wire W is inserted through the general electric wire holding portion 12 to perform the wiring repair. In the electric wire of the part where the tool 10 is slid, the specific electric wire W-S can be reliably positioned at the center of the general electric wire W.

When the wiring jig 10 comes to the position of the branch electric wire W'while the wiring jig 10 is sliding, the outer peripheral wall 10d of the wiring jig 10 is opened as shown in FIG. By extending the wire arrangement jig 10 to the wire, the wire laying jig 10 can be passed through the branching point without being removed from the electric wire W.

As described above, the wire laying jig 10 is partially wound by sliding the wire laying jig 10 with the adhesive tape 3, and this work is performed on the entire wire to lay the wire laying jig 1.
Remove 0 from the wire. The wiring jig 10 is used as a protector for arranging the formed wire harness on a mounted panel such as a vehicle without fixing the wire W to the wire W by fixing the wire W with a tape. Is also good.

As is apparent from the above description, in the wire harness wiring jig of the present invention, the small-diameter tubular portion is located at the center of the large-diameter tubular portion formed by curving the outer peripheral wall, and the small-diameter tubular portion is formed. Since the portion serves as the specific electric wire holding portion and the large-diameter tubular portion serves as the general electric wire holding portion, the wired specific electric wire can be reliably arranged at the center of the general electric wire.

The wire harness formed by using the above wiring jig is formed by sliding along the electric wire from the above-mentioned state and partially winding and binding the electric wire at the passing portion with an adhesive tape. Therefore, the specific electric wire is located at the center of the general electric wire in every part.

Further, since the large-diameter cylindrical portion forming the general electric wire holding portion is formed by bending the outer peripheral wall made of a flexible material, it is possible to perform the sliding work of the wiring jig as described above. When it is located at the location of the branch electric wire, the wiring jig can be passed through without removing the electric wire by removing the curvature of the outer peripheral wall. Therefore, it is not necessary to perform extra work for removing the wiring jig from the wired electric wire, so that workability can be improved.

Furthermore, when the specific electric wire holding portion and the general electric wire holding portion are formed as separate bodies which can be detached and attached, the above-mentioned general electric wire holding portion can be removed from the wire harness in which the wiring jig is formed. It is only necessary to separate the outer peripheral wall that constitutes it. Therefore, the workability of removing the wiring jig can be improved, and the displacement from the center position of the specific wire due to the forcible removal of the wiring jig can be prevented.
