Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness laying method and a wire laying jig for an electric wire for an important circuit, and in particular, an electric wire for an important circuit can be positioned and held at the center of an electric wire for a general circuit. To do so.

[0002]

2. Description of the Related Art Conventionally, a wire harness for a vehicle is shown in FIG.
As shown in FIG. 6, 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 wire group is wrapped and bound with a binding material such as tape 3 while lifting the wire group from the 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 flows through the power supply line, it is preferable to locate the power supply line at a central position where disconnection is less likely to occur due to interference from the vehicle panel or the like.

However, in the conventional method of binding a wire harness shown in FIG. 16, 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. There is no means for positioning and holding the important circuit electric wire to be positioned at the center position of the wire or the like at the center of the electric wire group. At the time of wiring work, the worker should bind the important circuit wires while centering them,
If it is not known which electric wire is the important circuit electric wire, it is not possible to center these electric wires for the important circuit. On the other hand, when the important circuit electric wires are recognized and the important circuit electric wires are attempted to be bundled by locating the important circuit electric wires at the center position when they are bound with the tape 3, the plural important circuit electric wires are usually provided. It is not easy to bind the electric wires while positioning them in the center.

Therefore, conventionally, as shown in FIG. 17, it is possible to surely solve the problem that the important circuit wire W-S to be located at the center of the cross section of the wire harness may be located at the outer peripheral portion of the wire harness. I couldn't.

To solve the above problem, a binding tool 4 dedicated to positioning the constant wire as shown in FIG. 18 has been proposed. (Actual Kaihei 1-222574) The above-mentioned binding tool 4 is provided with three projections 4b extending radially on the outer periphery of the substantially annular holding member 4a, and the holding circuit 4a is formed by a tape with the important circuit electric wire W-S accommodated therein. A wire harness in which the wires for the important circuit and the tie 4 are fixed to each other and the other wires W are arranged on the outer peripheral surface of the holding member 4a for the wires for the important circuit, and the outer circumferences of these wires to be bundled are bound by the tape 3. Is formed.

When the above-mentioned binding tool is used, a plurality of protrusions 4b
Since the tape 3 is wound around the outer peripheral surface of the wire harness, the outer diameter of the wire harness to be focused needs to correspond to the outer diameter of the binding tool 4. Therefore, there is a problem in that a large number of tying tools 4 that are separate parts must be prepared according to changes in the outer diameter of the wire harness. Further, since the holding member 4a has a large opening and is open outward, the important circuit wire W-S is more likely to come out than the holding member 4a, and it may not be possible to position and hold the wire at the center of the wire harness. Since there is no means for holding the electric wires W arranged on the outer periphery, there is a problem that it takes time and effort to wind the tape to bundle the whole electric wire group.

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

According to a fifth aspect of the present invention, after the adhesive sheets on both sides in the vertical direction are bonded to each other to form a sandwich, the upper and lower sides of the central portion where the electric wires for the important circuit are located and the outer periphery of the central portion are attached. Since the wire harness is wound so as to surround it and the adhesive tape is wound around and fixed to the outer peripheral surface of the wire harness, the wire harness can be changed from a flat shape to a circular cross section, and is preferably used in a place where the circular cross section is preferable at the time of wiring.

According to the sixth aspect, by moving the wire arranging jig, the position of the general circuit electric wire and the important circuit electric wire is restricted by the wire arranging jig even in a region other than the position restricted by the adhesive sheet. The important circuit electric wire can be positioned at the center of the general circuit electric wire and can be surrounded by the general circuit electric wire.

According to a seventh aspect of the present invention, the wiring jig has a structure in which an H-shaped substrate portion is provided at the upper end of a vertical shaft portion that is detachably fixed to the wiring drawing board. Grooves are provided in the vertical portions on both sides of the board portion, and electric wires are inserted into the groove portions and wired in a vertical parallel manner. Since it can be positioned in the center of the, the general circuit wires can be easily laid in parallel in the grooves on both sides in the vertical direction, and the center between the both sides of the general circuit wires can be easily The important circuit wire can be positioned at the position. In addition, the adhesive sheet can be easily attached to the electric wires for general circuits arranged in the vertical direction, and can be easily removed from the wiring jig, which facilitates the wiring work. According to the eighth aspect, since the wiring jig of the seventh aspect is movable, as described above, the position regulation of the electric wire can be easily performed even at a position other than the position where the electric wire is regulated by sticking the adhesive sheet. It can be carried out.
