Abstract

PROBLEM TO BE SOLVED: To prevent a exposed wire part from being conspicuous by applying a liquid of the same color as a binding tape to the outer peripheral surface on the exposed wire not concealed with the binding tape at the position where a trunk line and a branch line part from each other. SOLUTION: Black tapes T1 and T2 are wound around the trunk line W1 of a wire harness W/H and the branch line W2 led out from a branch position respectively in a half-wrapped form for binding. In other words, the tape T1 is wound around the trunk line X1 from one end thereof to the other along an arrow X direction, while being wound in a cross form at a position P for continuity to the other end. Also, the tape T2 is wound around the branch line W2 from the end thereof to the position P. Thus, an approximately triangular part 3 not covered with the tape T1 appears at the cross-wound position. A black coating liquid 5a of the same color as the tape is, therefore, sprayed to the part 3, or the part 3 is preliminarily covered with a sheet 6 of the same color, thereby keeping the part 3 not conspicuous.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile wire harness, and in particular, at a position where a trunk line and a branch line branch, the wire cannot be completely covered by winding a binding tape and the wire is exposed. It is intended to improve the part.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
In the wire harness W / H consisting of, the main line W1 and the branch line W2 branching from the main line W1 are wrapped with tapes respectively to cover them, thereby binding the electric wire group and protecting the electric wires. Usually, tape T for main line W1
1 is wound from one end toward the other end, and when the branch line W2 is at the branch position P, the tape T1 is twisted and continuously wound toward the other end. Also, branch line W2
Then, the tape T2 is continuously wound from the terminal side toward the branch position P.

As described above, when the tapes T1 and T1 are wound around the trunk line W1 and the branch line W2, at the branch position P, the tape T1 on the trunk line W1 side is twisted while the tape T2 on the branch line W2 side is wound. Since the wire can be wound only up to the base of the branch line W2, the electric wire of the trunk line W1 is exposed, and in particular, the part S on the side opposite to the branch side from the branch line W2 has a part 3 where the substantially triangular tape cannot be wound. The electric wire w is exposed at this portion 3.

[0004]

As described above, in the tape-wound main line W1 and branch line W2, the tape T
If there is an exposed portion 3 where 1 and T2 are not wound, the color of the electric wire w is different from that of the tapes T1 and T2, and the colors of the tapes T1 and T2 are usually black, and the colors of the electric wire w are yellow, red and green. As a result, the tapes T1 and T2 are not wound, which is a noticeable problem. Therefore,
Although it is desired to prevent the electric wire from being exposed, it is very difficult to completely remove the exposed portion 3 and cover the electric wire w in the operation of winding the tape.

The present invention has been made to solve the above problems, and an object thereof is to make an exposed portion of an electric wire, which is generated when a tape is twisted and wound around a branch line branching position, inconspicuous. There is.

[0006]

In order to achieve the above object, in the present invention according to claim 1, in a wire harness composed of a large number of electric wire groups, at a position where a branch line branches from a main line, from one side of the main line. The wound tape is wound at the branching position and wound on the other side so as to be continuous with the other side, while the tape is wound around the branch line from the branching position to the tip and exposed without being covered with the taped at the branching position. It is characterized in that a coating liquid of the same color as the tape is applied to the outer peripheral surface of the electric wire.

In the wire harness having the above structure, since the coating liquid of the same color as the tape is applied to the outer peripheral surface of the electric wire on which the tape is not wound, the electric wire is not conspicuous in appearance and is covered with the tape. It looks like

Further, in a wire harness according to a second aspect of the present invention, in a wire harness including a large number of electric wire groups, a tape is wound around the main line and the branch line to bind them together, and the branch line is branched off from the main line. Wrap a sheet of the same color as the tape wrapped around the wire harness from around the branch position to the entire outer peripheral surface of the main line,
It is characterized by covering a part of the wire so that it is not exposed.

A sheet of the same color as the tape is wound around the branch position before winding the tape, and then,
The tape to be wrapped around the wire harness trunk line may be loosely attached. Alternatively, the sheet of the same color may be wound around the branching position after the main line tape is twisted and wound. In this way, since the sheet of the same color as the tape is wound around the branching position around the entire outer peripheral surface of the main line, the electric wire is not exposed by being covered with the tape and the sheet.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a first embodiment, in which a black tape T is provided on each of a trunk line W1 of a wire harness W / H and a branch line W2 branched from a branch position P.
1. T1 and T2 are wrapped in a half wrap to be united.
That is, in the main line W1, the tape T1 is wound from one end to the other end in the direction indicated by the arrow X, and at the branch position P where the branch line W2 branches, the tape T1 is wound.
Is squeezed and made continuous to the other end. Further, the branch line W2 extends from the terminal side toward the branch position P and the tape T
2 is wrapped around.

The colors of the tapes T1 and T2 are not limited to black and may be gray or the like, but the tapes T1 and T2 have the same color. Also, the branch line W2 may be wound toward the terminal side from the branch position P.

As described above, the portion of the main line W1 which is laid at the branch position P is not covered with the tape T1, and in particular, the substantially triangular portion 3 is provided on the side opposite to the branch line branch side. Exists. Particularly, when the diameter of the branch line W2 is large, the exposed portion 3 is also large.

For the exposed portion 3, tapes T1, T
The black coating liquid 5a of the same color as 2 is sprayed from the spray 5 to apply the coating liquid 5a to the outer peripheral surface of the electric wire w of the above portion 3. Alternatively, a brush may be used instead of spraying.

Thus, when the coating liquid 5a is applied to the outer peripheral surface of the electric wire w in the exposed portion 3, the electric wire w has the same color as the tapes T1 and T2, and the electric wire w is exposed from the tape T1. , It becomes inconspicuous and the tape T1 appears to be wound.

2 to 5 show the second embodiment, and the second embodiment
In the embodiment, the sheet 6 shown in FIG. 2 is used. This sheet 6 is cut into a rectangular shape, and the opposite side 6
A semi-circular cutout is formed in a and 6b toward the center of the sheet to form cutouts 6c and 6d, and an adhesive is applied to one side of the sheet, and from the same black color as the tapes T1 and T2. Become.

As shown in FIG. 3, the sheet 6 is wound around the branch position P before the tape T is wound around the trunk line W1 and the branch line W2. At this time, as shown in FIG. 4, when the cutout portions 6c and 6d are attached so as to cover the branch position P of the branch line 2, the trunk line W1 at the branch position P is completely covered,
Moreover, the sheet 6 does not wrinkle.

As described above, the branch position P is covered with the sheet 6, the part 3 where the tape is not wound, which is generated when the tape is twisted, is covered in advance, and the electric wire w is covered. Then, as shown in FIG. 5, the main line W1 and the branch line W2
The tapes T1 and T2 are respectively wound around and in the same manner as in the first embodiment.

6 and 7 show a modification of the second embodiment, in which the tapes T1 and T2 are wound around the main line W1 and the branch line W2, the sheet 6 is wound around the branch position P, and the tape T1 is wound around. The uncovered portion 3 is covered so that the electric wire w is not exposed.

[0019]

As is apparent from the above description, in the invention according to claim 1, in the position where the branch line branches from the trunk line, the tape wound around the trunk line is exposed and is not covered with the tape and exposed. Since the same coating liquid as the tape is applied to the outer peripheral surface, the above-mentioned electric wires are not conspicuous, and it seems that all the electric wires at the branch position are wound with the tape.

In the invention according to claim 2, at the branch position of the main line from the branch position, a sheet of the same color as the tape wound around the wire harness is wound around the branch position of the branch line to the entire outer peripheral surface of the main line, to The part is covered so that it is not exposed. Therefore, there is an advantage that the electric wire is not exposed at the branch position and the appearance is improved, and the electric wire is protected by the sheet.
