Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wire harness in which a large number of electric wire groups are wound with a tape to be focused and protected, and when double tape winding is required, it is possible to confirm at a glance that the wire is wound twice. .
[0002]
[Prior art]
Conventionally, the wire harness of the wire harness W / H that is routed in an automobile is often bundled and protected by tape winding, but when important wires are included or when waterproofing is required to be ensured To ensure that the wires are protected from external interference and flooding, the tape is double wrapped.
[0003]
In this case, when the sections A to B of the wire harness W / H are wound once with the tape 1 as shown in FIG. Since the tape 1 wound on the wire cannot be visually checked, in the conventional inspection of the electric wire double winding operation, a part of the tape 2 wound second time is peeled to confirm the presence of the first tape 1. The method has been taken.
[0004]
However, according to such a tape winding electric wire protection structure, in order to confirm the presence of the first winding tape 1 in the inspection as described above, it takes time and effort to peel off the tape 2 wound from above the tape 1, Moreover, when the tape 2 once wound is peeled off and then wound again, the adhesive strength of the peeled tape 2 is deteriorated, and in particular, the end of the peeled tape 2 is easily turned over.
[0005]
For example, in Japanese Utility Model Publication No. 64-009315, as shown in FIG. 4, sections A ′ to B ′ in which both ends of sections A to B in which electric wires are double-taped are respectively extended are blue tape 3. The section A to B that should be double protected from above is wound twice using a tape of a color other than blue, for example, the black tape 4. Thus, by making the color of the tape 3 of the first roll and the tape 4 of the second roll different from each other, it is possible to indicate that the tape is wound twice without peeling off the tape 4 wound on the second roll. It can be confirmed at a glance.
[0006]
[Problems to be solved by the invention]
However, when tapes having different colors are used as described above, the different color tapes are located adjacent to each other, and the color difference is too conspicuous from the outside. Usually, the wire harness is wound with black tape so as not to be noticeable. However, when a tape of a different color is wound only for confirmation of double tape winding, the wire harness is not preferable in appearance.
[0007]
This invention is made | formed in view of the said problem, and makes it a subject to enable it to confirm double tape winding, without being conspicuous on an external appearance.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention focuses and protects a group of electric wires constituting a wire harness routed in an automobile by double winding with a tape,
The first tape is wound by extending the required dimension from both ends of the double winding section, and the second winding tape is wound around the double winding section, and the first winding is wound from both ends of the second winding tape. The tape is exposed,
While the tapes used for the first and second rolls are both black, the first roll and the second roll of black are made different from non-glossy and glossy , and the tape is double-wound. Provided is a wire harness that can be confirmed as being connected.
[0009]
As described above, both the color of one turn th tape and two-th-turn of the tape to expose are less noticeable wire harness itself as black color, but different in appearance the eyes a roll first and second spool As you can see, there is a difference between no gloss and gloss . Thereby, the inspector can confirm the presence of the exposed first winding tape from the outside without conspicuous the difference between the wire harness itself and the first and second winding tapes.
[0010]
Thus, the color of the tape is a black tape that is widely used for binding wire harnesses . Specifically, after a glossy black tape is wound around the wire harness W / H so as to protrude from both sides of the tape double winding section of the wire harness W / H, one end of the tape wound around the first winding is exposed. Start winding a glossy black tape as the second tape in the tape double winding section, double-wrap the tape so that the other end of the first tape is exposed. Wound around the section.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a wire harness W / H to be routed in an automobile is wound with a black tape 10 without gloss of the first roll and a black tape 11 with gloss of the second roll around the double tape winding section. ing. Each of these tapes 10 and 11 is made of a vinyl tape, and is made of an adhesive tape in which an adhesive is applied to one surface on the inner surface side.
[0012]
The glossy black tape 10 of the first roll and the black tape 11 of the second roll are wound in a double half wrap between the double tape winding sections AB.
The glossy black tape 10 of the first winding is wound in the section A′-B ′ having a width substantially equal to the tape width from both ends of the double tape winding section AB. The black tape 11 without gloss is exposed from both ends of the black tape 11.
[0013]
Specifically, as shown in FIG. 2 (A), from the starting point A ′ extended by a length L from one end A of the double tape winding sections A to B, the first glossy black tape 10 is attached to the outer periphery of the electric wire group. Half wrap around the surface and wind in the direction indicated by the arrow in the figure.
As shown in FIG. 2 (B), the winding is completed at the end point B ′ extended by the length L from the other ends B of the double tape winding sections A to B, and the first tape winding operation is completed.
[0014]
Next, as shown in FIG. 2 (C), using the glossy black tape 11 of the second winding, the outer peripheral surface of the first tape 10 starting from one end A of the double tape winding sections A to B Then, the section A-B is double-wrapped with the tapes 10 and 11.
[0015]
By winding the tapes 10 and 11 as described above, the tapes 10 and 11 are double-wound in the double tape winding section A-B, and the first glossless tape 10 of the length L is exposed on both sides thereof. It is assumed that
[0016]
With the tape winding structure, the tapes are wound twice in the protection sections A to B where the wire harness W / H is wound with the double tape, but at the both ends of the glossy glossy tape 11 of the second roll. The first glossless glossless tape 10 is exposed for a length L, and the gloss of both tapes 10 and 11 can be visually confirmed from the outside. Therefore, the presence of the glossless tape 10 wound in the first roll can be visually confirmed from the outside without removing the tape 11 with the second roll gloss. And since the tape 10 of the 1st roll and the tape 11 of the 2nd roll are the same black, the external appearance problem that the difference in the color of a tape stands out does not arise.
[0018]
【The invention's effect】
As is clear from the above description, according to the present invention, in the double winding section of the tape, it is possible to visually confirm whether the double winding operation of the tape is performed without removing the second tape. it can.
In addition, since the first and second tapes have the same color, there is an advantage that the wire harness is not conspicuous when arranged in an automobile.
[0019]
If the color of the tape is black, since it is a widely used tape, there is an advantage that the portion for visual confirmation is not particularly noticeable.
