DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness convergence section wound around a wire harness a plurality of times at the same position.

[0002]

2. Description of the Related Art Conventionally, in converging a wire harness, a tape must be double-wound as necessary. For example, as shown in FIG. 3, when a wire harness 2 is provided to penetrate a partition wall 1 that separates an engine side and a cabin side of an automobile, in order to prevent water droplets and the like entering the engine side from entering the cabin side. An elastic grommet 3 having a tube 3A formed in the center portion is fitted into a hole formed in the partition wall 1, a wire harness 2 is passed through the grommet 3, and further a gap between the tube 3A of the grommet 3 and the wire harness 2. Is wound on tape. In this case, double wrap the tape to ensure waterproofness,
In order to be able to visually confirm that this has been performed reliably, for example, as disclosed in Japanese Utility Model Publication No. 6-48676, the tape 4 used for the first tape winding and the second tape 4 are used. The tape 5 used for the tape winding is made of a different color from each other, and the winding start positions are shifted from each other. That is, as shown in FIG. 3, when the twice-wound section of the wire harness 2 is between A and B,
The once winding section is a section A 'to B' longer than the section between A and B.
To

[0003]

According to the above construction, the tape 4 used for the first tape winding and the tape 5 used for the second tape winding are of different colors, and each of the windings is started at the beginning of each winding. Since the position is shifted, whether or not the tape is double-wound can be surely confirmed visually. However, it is difficult to confirm how the first tape winding is performed. For example, a part where the first tape winding must be half-wrapped in the entire area is not wrapped due to an operation mistake or the like ( When the portion 6) shown in FIG. 4 occurs, it cannot be confirmed because it is hidden by the second tape winding. For this reason, a product that cannot obtain sufficient waterproofness may be produced, and it has been difficult to secure stable quality.

[0004] Further, a step of shifting the winding start position is required in the case of mechanical winding, resulting in a time loss, and there is a possibility that productivity may be reduced as compared with a case where the winding start position is not shifted.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wire harness convergence portion that can reliably achieve waterproofness and improve productivity.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire harness convergence section which is wound twice on the same portion of a wire harness, and a second time.
This is achieved by a wire harness converging section, wherein the wound tape winding layer has translucency. First time
The wound tape wound layer is preferably a tape wound layer for which the winding state needs to be confirmed. It is preferable to use a transparent tape as the translucent tape.
According to this configuration, the same portion of the wire harness is used twice.
Twice out of the tape winding layers taping over the
Since the tape wound layer to be wound on the eye is made of a tape having a light transmitting property, the tape is wound for the second time through this outer tape winding layer .
The winding state of the tape winding layer to be cut can be confirmed. Then, since the tape wound first time can be seen through the tape wound second time, there is no need to shift the first tape winding start position and the second tape winding start position.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a wire harness focusing section 10 of the present embodiment. The wire harness concentrating portion 10 of this embodiment is formed by winding the same portion of the wire harness 2 twice with tape. In addition,
In FIG. 1, the same parts as those in FIG. 3 described above are denoted by the same reference numerals. In FIG. 1, the lower tape 4 used for the first winding of the tape is entirely colored, and the upper tape 11 used for the second winding of the tape is translucent. In this case, by making the upper tape 11 transparent, the winding state of the lower tape 4 can be checked through this. Thereby, for example, the lower tape 4
Can be confirmed through the upper tape 11 even if there is a portion that is not wrapped due to a work error or the like where the entire area must be half-wrapped. As a result, good / bad can be easily determined,
Product quality can be improved.

Further, by making the upper tape 11 transparent, it is possible to visually check whether or not the double winding is reliably performed. This eliminates the need to shift the winding start position of the lower tape 4 and the winding start position of the upper tape 11. As a result, in the case of mechanical winding, the step of shifting the winding start position is not required, so that there is no time loss and productivity is improved as compared with the case where the tape winding start position is shifted. In this way, by using a transparent upper tape 11 used for the second tape winding, the winding state of the lower tape 4 can be easily visually checked through the upper tape 11. Also, it can be checked at the same time whether double winding is being performed. Therefore, the quality and productivity can be improved in the manufacture of the wire harness convergence unit 10.

On the other hand, FIG. 2 is a diagram showing a case where the wire harness focusing section 10 of the embodiment is applied to an automobile. Parts common to those in FIG. 3 described above are denoted by the same reference numerals. As shown in this figure, even after the grommet 3 is fitted to the partition wall 1 or even from a position away from the partition wall 1, the winding state of the lower tape 4 can be easily visually checked through the upper tape 11. Can be. Also, it can be checked at the same time whether or not the double winding of the lower tape 4 and the upper tape 11 is performed.

[0010] In the above-described embodiment, the double winding is used, but the winding may be twice or more. in this case,
All of the tape winding layer outside the tape winding layer whose winding state is desired to be checked may be wound with a transparent tape. In the above embodiment, the lower tape 4 used for the first tape winding is colored as a whole, but this is for the purpose of easily confirming the winding state. If the state can be confirmed, it may be transparent. Also,
In the above embodiment, the lower tape 4 used for the second tape winding is made of a transparent material. However, the material may be colored if it is not transparent and is translucent so that the opposite side can be seen through. Absent. In the above embodiment, the lower tape 4
Although the winding start position of the upper tape 11 and the upper tape 11 are matched, the winding start position is not necessarily limited to this, and the winding start position may be shifted as necessary.

[0011]

As described above, according to the present invention,
Tape winding wound on the second time among the tape winding layer is a tape wound over twice the same position of the wire harness
Layer is made of translucent tape, through which
The winding state of the tape winding layer wound first time can be easily checked visually, so the tape wound first time
It is possible to easily determine whether the winding state of the wrapping layer is good or bad, thereby improving the quality of the product. Then, since the tape used for the first tape winding can be seen through the tape used for the second tape winding, the tape can be doubled without shifting the first tape winding start position and the second tape winding start position. You can check the winding. Further, in the case of mechanical winding, since the step of shifting the winding start position is not required, productivity can be improved as compared with the case where the tape winding start position is shifted.
