2. Description of the Related Art Conventionally, a wire harness is generally assembled as follows. That is, an electric wire support tool for supporting an electric wire forming a wire harness is arranged at a predetermined position on an assembly drawing board, an electric wire cut into a predetermined length is received by the support tool, and the electric wire support tool is provided along the support tool. By arranging the wires two-dimensionally, a branch-shaped electric wire bundle is formed according to the purpose. Then, the outer circumference of the electric wire bundle is bound with tape or the like so that the electric wire bundle is not separated, and external parts such as clamps, protectors and connectors are attached as necessary.

In recent years, for example, in wire harnesses for automobiles, since the number of electric components used has increased,
The branch shape has become very complicated. For this reason, in some cases, it is necessary to manufacture a wire harness that is not only two-dimensionally branched but also three-dimensionally branched. In this case, form the wire harness two-dimensionally,
Deforming it into the finally required three-dimensional shape causes an inconvenience that the number of man-hours for the work is increased and the electric wire is twisted and an unreasonable force is applied. In addition, if the bundle of electric wires once taped is forcibly bent, various problems occur such that the accuracy of the three-dimensional dimensions of the wire harness deteriorates and the appearance of the wire harness also deteriorates.

In order to solve such a problem, there has been proposed an electric wire support tool capable of laying an electric wire three-dimensionally from the beginning and assembling a wire harness into a predetermined three-dimensional shape. FIG. 8 is a perspective view showing a state in which the wire bundles E1, E2, and E3 that form the wire harness WH are laid using a conventional wire support for three-dimensional wiring.

The electric wire bundle E1 is a trunk electric wire bundle which constitutes the wire harness WH, and the electric wire bundles E2 and E3 are branched electric wire bundles branched from the trunk electric wire bundle E1. The bundles of electric wires E1 and E2 are laid in the horizontal direction on the same plane by the support tool 2 arranged on the assembly drawing board 1. Further, reference numeral 3 is an electric wire support for three-dimensionally arranging the electric wire bundle E3. With this wire support 3, the wire bundle E
3 is erected upward from the plane including the bundled electric wire bundles E1 and E2 and wired.

Then, after the electric wire is passed between the bent portion support members 5 to be laid in the horizontal direction, the electric wire is bent by the bent portion support member 5 and rises upward to support the connector C attached to the tip of the electric wire. Hook on the member 6. Thereby, the wire harness WH can be laid in a desired three-dimensional shape.

[0007]

However, the wiring work for bending the electric wire by the bending portion support member 5 and raising it upward is much more difficult than the work for wiring the electric wire along the assembly drawing board 1. It's hard to work. Moreover, when arranging a large number of electric wires that constitute the trunk electric wire bundle E1 that does not need to be vertically raised, the support 4 and the tip support member 6 are higher in height than other electric wire supports, and therefore work is performed. Get in the way.

Further, after arranging the electric wires three-dimensionally,
Although taping is performed to bind the wire bundle E3, the support 4 is an obstacle during the taping work, which makes the work difficult. Due to these various problems, there is a new problem that the workability of assembling the wire harness is poor.

Therefore, an object of the present invention is to provide an electric wire support for three-dimensional wiring which can improve the workability of forming a wire harness into a three-dimensional shape.
