Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness for protecting a bundle of a large number of electric wires by tape winding.
When double tape winding is required, the double winding can be confirmed at a glance.

[0002]

2. Description of the Related Art Conventionally, a group of wires of a wire harness W / H routed to an automobile are often bundled and protected by tape winding. However, when important wires are included, it is necessary to ensure waterproofness. In some cases, the tape is double wrapped to ensure that the wires are protected from external interferences and flooding.

In this case, as shown in FIG. 3, after the section A to B of the wire harness W / H is wound once with a tape 1, the same section A to B is wound twice with a tape 2 from above.
Since the first winding tape 1 cannot be visually observed from the outside, conventionally, in the inspection of the double winding operation of the electric wire, the first winding tape 1 is peeled off by removing a part of the second winding tape 2. Have been taken to confirm the existence of

However, according to such a tape-wound wire protection structure, as described above, in order to confirm the presence of the first tape 1 in the inspection, it is necessary to remove the tape 2 wound from the top of the tape 1. In other words, if the tape 2 once wound is peeled off and re-wound, the adhesive strength of the peeled tape 2 is deteriorated, and in particular, the end of the peeled tape 2 is easily turned up.

To solve the above problem, for example, Japanese Utility Model Laid-Open No. 64-0
In No. 09315, as shown in FIG. 4, a section A ′ in which both ends of sections A and B where the electric wire is double-taped is extended.
B ′ is wound once using a blue tape 3, and the sections A to B that are to be double protected from above are further wound twice using a tape of a color other than blue, for example, a black tape 4. . As described above, by making the colors of the first winding tape 3 and the second winding tape 4 different from each other, it is possible to confirm that the tape is double-wound without peeling off the second winding tape 4. So that they can be checked at a glance.

[0006]

However, when tapes of different colors are used as described above, tapes of different colors are located adjacent to each other, and the color difference is too noticeable from the outside. Normally, the wire harness is wrapped with black tape so as to be inconspicuous. However, if a different color tape is wrapped just to confirm double tape winding, the appearance of the wire harness is not preferable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to enable double tape winding to be confirmed inconspicuously in appearance.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method in which a group of wires constituting a wire harness routed in an automobile is double-wrapped with tape to protect the bundle. The second winding tape is wound around the above-mentioned double winding section while the second winding tape is wound around the both ends of the double winding section while extending the required length from both ends of the double winding section. The tape is exposed, and the tapes used in the first and second windings are made the same color. On the other hand, the tapes of the first and second windings have different colors, lightness and / or luster. It provides a wire harness having a configuration that can be confirmed to be double-wound.

As described above, the colors of the first tape and the second tape to be exposed are the same, but the saturation, lightness and / or luster of the tape can be confirmed so as to confirm the difference in appearance. Has a difference. Thereby, the presence of the exposed first-turn tape can be confirmed from the outside without making the difference between the first-turn and second-turn tapes noticeable.

[0010] Specifically, the color of the tape is preferably a black tape widely used for binding wire harnesses. That is, after winding a glossy black tape around the wire harness W / H so as to protrude on both sides of the tape double winding section of the wire harness W / H, one end of the tape wound in the first winding is exposed. Start winding a shiny black tape as the second tape in the double winding section of the tape, wind it in double half wrap, and wind it around the double winding section of the tape so that the other end of the first tape is exposed ing.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the wire harness W / H routed to the vehicle has a double tape winding section,
A first black glossy tape 10 and a second black glossy tape 11 are wound. Each of these tapes 10 and 11 is made of a vinyl tape and is made of an adhesive tape having an inner surface coated with an adhesive.

[0012] The first roll of the glossy black tape 10
And the glossy black tape 11 of the second winding is double half-wrapped between the double tape winding sections AB.
The above-mentioned first non-gloss black tape 10 is wound around a section A′-B ′ having a width substantially equal to the tape width from both ends of the double-tape winding section AB, and therefore, a second luster gloss. The first black glossy black tape 10 is exposed from both ends of the present black tape 11.

More specifically, as shown in FIG. 2A, from the starting point A ', which is extended from the one end A of the double tape winding section A to B by the length L, the first unpolished black tape 10 is connected to the electric wire. Half-wrapped around the outer peripheral surface of the group, and wound in the direction indicated by the arrow in the figure. As shown in FIG. 2 (B), winding is completed at an end point B 'which is extended by a length L from the other end B of the double tape winding section A to B, and the first winding operation of the tape is completed.

Next, as shown in FIG. 2 (C), using the glossy black tape 11 of the second winding, starting from one end A of the double tape winding section AB, the first winding of the tape 10 is started.
Half-wrap around the outer surface of the tape, tapes 10 and 11
, The section AB is wound in double half-wrap.

By winding the tapes 10 and 11 as described above, the double tape winding section AB becomes the tape 1
0 and 11 are double-wound, and the glossy tape 10 of the first turn is exposed on both sides by a length L.

With the above-described tape winding structure, the tape is double-wrapped in the protection sections A and B in which the wire harness W / H is double-taped, but the glossy glossy tape of the second winding is used. At the both ends of the first roll, the dull glossy tape 10 of the first winding is exposed by the length L, respectively,
The gloss of both tapes 10 and 11 can be visually confirmed from the outside.
Therefore, the presence of the glossy tape 10 wound in the first winding can be visually confirmed from the outside without peeling off the glossy tape 11 in the second winding. In addition, since the first winding tape 10 and the second winding tape 11 are the same black, there is no appearance problem that the difference in tape color is conspicuous.

The difference in appearance of the black tapes 10 and 11 of the first and second windings is not limited to the above-mentioned luster, but the saturation or lightness is different or these elements are combined. They may be different. Further, as long as the first and second winding tapes are of the same color, the tape is not limited to black, but may be dark blue or the like and have different lightness, gloss, and / or saturation.

[0018]

As is apparent from the above description, according to the present invention, in the double winding section of the tape, it is visually observed whether the double winding operation of the tape is performed without peeling off the second tape. You can check with. In addition, since the first and second winding tapes have the same color, there is an advantage that the wiring harness is not noticeable when the tape is installed in an automobile.

If the color of the tape is black, it is a general-purpose tape, so that there is an advantage that the portion for visual confirmation is not particularly noticeable.
