Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for assembling wire harnesses in which a required number of electric wires are distributed and routed according to specifications using a required number of guide nails erected at predetermined positions on a board as a guide. Concerning convergence methods.

Conventionally, when assembling a wire harness for an automobile, as shown in FIG.
was installed, and using guide nails b as guides, the required number of electric wires c was distributed and wrapped in tape to the left and right according to the specifications. The bundle of wires must be lifted from the board a and the tape roll placed under it, which not only makes the tape winding work very troublesome and takes a long time, but also makes it difficult to wrap the bundled wires with tape during the work. There were defects such as sagging in areas that were not covered. Another drawback was that the tape-wrapped part became hard, making it difficult to assemble it into a car.

The present invention provides a method for converging electric wires that eliminates the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 2 to 4, 1, 1'...... are guide nails implanted on the above-mentioned board, and each of the guide nails 1, 1'...... has a forked shape on the upper part. Arm portions 2, 2' are formed.

The guide nails 1, 1' having such a configuration use their arms 2, 2' to sort the electric wires 3 according to the specifications, but in the present invention, the electric wires 3 are converged in advance. At least two of the above-mentioned guide nails are used to attach a flexible sheet-like material 4 made of foamed urethane or the like with adhesive applied to the surface.
are fixed with the tips of the guide nails 1, 1', etc. protruding from the surface of the sheet-like material 4. Then, the required number of electric wires 3 are distributed according to the specifications, and after the distribution is completed, the above-mentioned sheet-like material The object 4 covers the electric wire 3 and converges it.

The sheet-like material 4 is symmetrical along the insertion direction of the wires 3 (in the case of a branch, in the direction of the main line), with the sheet-like material 4 wrapping around the bundle of electric wires 3, and both sides 4a, 4b have both pieces 4a, 4
The holes 5a, 5 are scattered symmetrically with respect to each other in b.
a'......, 5b, 5b'...... are formed, respectively.

One of the holes 5a, 5a'..., 5b, 5b'...... is fixed with a predetermined guide nail 1, 1'...
... and its pair of arm portions 2, 2', and the pair of arm portions 2, 2' of the guide nails 1, 1'... ' is shaped so that it can be inserted.

Therefore, in order to wrap the electric wire 3 with the sheet-like material 4, first, a piece of the sheet-like material 4, for example 4a
The holes 5a, 5a'...... are inserted into the arm portions 2, 2'... of at least two predetermined guide nails 1, 1'....... At this time, the sheet-like material 4
The upper portions of the guide nails 1, 1', etc. are forked to form a pair of arm parts 2, 2', so the arm parts 2,
It is locked at 2'.

Next, after sorting the electric wires 3 according to the specifications, the piece 4b paired with the piece 4a was folded back, and the holes 5b, 5b'...... were locked with the holes 5a, 5a'... It is inserted into the arms 2, 2', and the wire 3 is covered with the surface coated with adhesive.

In addition, the adhesive is applied to the holes 5a, 5a'......, 5b, 5
It must be coated except for the area near b'...

After assembling the wire harness by converging all the predetermined convergence points using the method described above, guide nails 1,
A desired wire harness can be obtained by pulling out the wire harness and the sheet-like material 4 integrated therewith from 1'.

As described above, the convergence method of the present invention eliminates the need to lift each bundle of wires from the board and condense them, compared to conventional tape wrapping, which not only improves work efficiency but also prevents looseness in the bundle of wires. This also eliminates accidents such as injuries to workers' hands caused by guide nails.

Furthermore, since a flexible sheet-like material is used as the concentrator, the collision between the wire harness and the wall of the actual vehicle is buffered by the flexible sheet-like material, and the protection of the wire harness becomes even more reliable.

Furthermore, the wire harness has a flexible convergence, which greatly improves the workability of the equipment on actual vehicles.

In the present invention, an adhesive or magic tape may be applied to the surface of the sheet-like article instead of the adhesive.
