Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a partially flattened wire harness and a wire holder used therein.

[Conventional technology]

For example, a wire harness for an automobile door must be installed in a narrow space within the door frame, so the conventional wire harnesses are complicated and time-consuming, and have low productivity.

Therefore, we installed the wire harness for the door on the cover plate inside the door (
There is a method of providing a flat trim board (Japanese Unexamined Patent Publication No. 61-9111).

However, since this method uses a bonding agent to flatten the electric wire, special equipment such as a bonding agent drying device is required, which limits the manufacturing location and increases costs. Also,
This is difficult in that cracks are likely to occur when branching and fixing branch lines from the main line depending on the arrangement of electrical components.

On the other hand, in order to partially flatten the wire, a plastic wire protector a as shown in FIG. 7 has conventionally been used.

This protector a consists of a gutter-shaped main body and a lid C. The main body has mounting plates d for fixing electric wires at both ends, and the main body and the lid C are provided with locking means consisting of a locking pawl e and a locking frame e2.

However, since the wire protector a is made of plastic in advance to match the shape of the installation space of a specific vehicle body, it is not versatile and is inconvenient. Furthermore, since the wire protector a is not equipped with a locking means for individual wires, a plurality of wires are stored in the wire protector all at once after the wiring is completed, and fixed to the mounting plate d by wrapping tape or the like. In order to avoid being unable to store the cable, extra length must be allowed for the wire, which results in wasted materials.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and there is no need to use a bonding agent or expensive special equipment to flatten the wire harness, and there is no need to use a bonding agent or expensive special equipment to flatten the wire harness. It is an object of the present invention to provide a method for manufacturing a wire harness that can take a free wiring configuration including branching out of the wire section, and a wire holder used therein.

[Means for Solving the Problems] In order to achieve the above-mentioned problems, the method for manufacturing a partially flattened wire harness of the present invention includes forming a U-shaped wire holding groove with an open top on a wiring table. In the method of manufacturing a wire harness, a plurality of wire locking pins are set upright, and a plurality of wires are sequentially hung in the wire holding groove one by one and routed along a predetermined route. A wire holder equipped with a means for locking a plurality of electric wires in a flat shape is removably attached to the wire holder, and the wire holder is used to lock a part of the wire in a flat shape at the same time as the wire is routed. Features.

In addition, the wire holder used for this purpose is provided with a plurality of wire clamping arms extending from one side of the board toward the other at appropriate intervals, and at least one of the opposing surfaces of the wire clamping arms and the board. It has a structure in which a plurality of wire check claws are provided in multiple stages.

The above configuration will be specifically described below with reference to drawings showing examples.

[Example] In Fig. 1, ``■'' is a wiring stand, on which a plurality of wire locking pins 2 are erected. The wire locking pins 2 are provided in advance along the two-dimensional path of a desired wire harness, and are each provided with a U-shaped wire holding groove 3 with an open upper end at the top.

4 is a wire holder for holding a part of the wire in a flat shape. As shown in FIGS. 2 and 3, this wire holder 4 is provided with a plurality of wire holding arms 6 on one side of a synthetic resin substrate 5 extending toward the other side at appropriate intervals. A plurality of electric wire non-return claws 7 are provided protruding in multiple stages on the inner surface of the arm 6 and the substrate surface facing the arm 6, respectively. Board 5
The length of the wire clamping arms 6 and the pitch between the wire clamping arms 6 can be freely selected. Moreover, the electric wire non-return claw 7 may be provided to protrude from either the electric wire clamping arm 6 or the substrate surface.

Furthermore, hook pieces 8 that engage with the wire holding grooves 3 of the wire locking pins 2 are provided at both ends on the side of the rising base 6a of the wire holding portion 6 of the board 5, and as shown in FIG. Ingredients 4
It is preferable to temporarily hold the wire between the wire locking bins 2. In place of the hook piece 8, a positioning groove 8' may be provided in a recess as shown in FIG. In addition, when the board 5 is formed to be long, it is preferable to provide a plurality of hook pieces 8 or positioning grooves 8' at appropriate intervals.

The base plate 5 and the wire clamping arm 6 of the wire holder 4 may be formed separately, and the two may be connected by screws, nuts, dovetail and dovetail fitting, or the like.

(Function) To manufacture a wire harness, as shown in Fig. 1, first, one electric wire W is routed along a predetermined route from one electric wire locking pin 2° to the other pin 2□. The length of the electric wire W is determined in advance, and there are terminals (not shown) at both ends.
