JPH0648676Y2 - Winding shape of tape for wire harness focusing - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has a wire harness converging portion which needs to be wound twice with a tape for the purpose of preventing water leakage, and is wound twice without peeling the tape. The present invention relates to a winding shape of a tape which enables confirmation of work.

[Conventional technology]

There are points in the wire harness bundling that require double wrapping of the tape if necessary.

For example, as shown in FIG. 3, when the wire harness W is routed through the partition wall P that partitions the engine side and the passenger compartment side of the automobile, water droplets or the like that have entered the engine side from the outside The wire harness W is inserted into the tube T which is erected at the center of the side surface of the grommet G having elasticity so as not to enter the inside of the room, and the annular recess provided on the outer peripheral portion of the grommet G is formed in the partition wall P. Fit and partition P
The gap between the wire harness W and the wire harness W is sealed, and the tape is wound around the tube T and the wire harness W to ensure waterproofness, but the tape is wound twice to ensure the waterproofness.

In addition to ensuring the waterproofness as described above, for the purpose of protecting external damage,
The wire harness may be wound twice if necessary, but as shown in FIG.
When the section B is wound twice with a vinyl tape, it is wound once with a commonly used black tape, and then the same section is wound twice with a black tape, only the second tape 2 is visible on the surface, It is extremely difficult to inspect by visual inspection to confirm the completion of the double winding work, and a method of peeling off the double winding tape 2 to confirm the existence of the first tape has been adopted.

[Problems to be solved by the invention]

The conventional inspection method as described above has the following problems.

(A) The inspection work performed by peeling off a part of the wound tape is extremely inefficient and troublesome.

(B) When the tape that has been wound once is peeled off and rewound, the adhesive strength and appearance shape of the tape are deteriorated, and the peeled end is particularly likely to be turned over.

The present invention has been made in view of the above problems, and makes it possible to easily perform an inspection that has already been performed twice by visual inspection.

[Means for solving problems]

The present invention is used for the second tape winding, in which a section excluding a part of the first tape winding section is set as the second tape winding section in the focusing section where the same portion of the wire harness is tape-wound twice. The tape used is characterized by having a color different from that of the first tape.

[Action]

In the first tape winding inspection confirmation performed after the second tape winding has been performed, it is possible to check at a glance whether or not the colors of both tapes are present, so that the conventional peeling inspection is unnecessary.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

The same parts as those in the conventional example are designated by the same reference numerals.

In FIG. 1, assuming that the section of the wire harness W required to be wound twice is between A and B, a section including A and B is A ′ to B ′.
A vinyl tape of a color other than black, for example, blue, is wound around.

Next, when the black vinyl tape 2 is wound between A and B,
The tape winding part is blue between A and A'and between B and B ', and A to A'
The area between B becomes black.

Therefore, the presence of the blue and black tapes can be easily confirmed by simply glancing at the converging part of the wire harness W, and there is no possibility that the inspection operation time will be significantly shortened and the quality of the tape winding part will be deteriorated. .

FIG. 2 shows a double-winding converging section which is implemented for waterproofing between the grommet G and the wire harness W.

In such a case, it is possible to know easily that the double winding has already been performed both after the grommet G is fitted on the partition wall P and at the position separated from the partition wall B.

In the above embodiments, the first blue tape is exposed on both sides of the double-wound black tape, but the blue tape may be on one side, not necessarily on both sides.

Further, although the color of the first tape is blue and the color of the second tape is black, which is conventionally used, any color may be used as long as the colors of both tapes are different.

〔effect〕

(A) The time required to confirm the completion of double winding is significantly reduced.

(B) The conventional confirmation work is troublesome, and there is a drawback that it is difficult to judge whether or not the tape is rewound if the peeling amount of the tape is small. However, in the case of the present invention, it can be judged at a glance and accurately. Therefore, confirmation errors are reduced.

(C) If the tape is peeled and then rewound, the quality of the wound portion of the tape may be deteriorated, but it is completely eliminated by the present invention.
