Description

  The present invention relates to a tape attachment structure for a wire harness, and more specifically, an adhesive tape is attached to a wire harness routed in a vehicle such as an automobile for fixing a vehicle body.

A wire harness to be routed in an automobile is preliminarily attached with a tape or band winding with an interval in the length direction, and is provided on a fixing member such as a body panel in an automobile assembly line. In many cases, the clamp is inserted and locked in the mounting hole and fixed to the vehicle body. Thus, when fixing a wire harness to a vehicle body using a clamp, it is necessary to provide a mounting hole in a vehicle body panel beforehand, and the manufacturing cost of a clamp starts.
Therefore, when the wiring harness has a flat upper surface, such as a body panel, and the wiring harness is mounted on the upper surface, or the wiring harness is routed between the upper and lower fixing materials In such a case, it is desired that the wire harness can be fixed to the vehicle body panel or the like using an adhesive tape without using a clamp.

  On the other hand, the applicant of the present invention disclosed in Japanese Patent Application Laid-Open No. 2004-320956 uses an adhesive tape for a roof harness routed between the lower surface of the roof panel and the upper surface of the ceiling material installed on the indoor side of the roof panel. Provides a structure to be fixed to the ceiling material. As shown in FIG. 8, the wire harness is fixed in a manner that the single-sided adhesive tape T1 is folded in two to fix the wire harness 100 between the adhesives on the inner surface, while the first double-sided adhesive tape T2 is attached to the ceiling material 101.

  In the wire harness vehicle body fixing structure using the adhesive tape of Patent Document 1, the single-sided adhesive tape T1 is wound around the required position of the wire harness 100 in advance in the wire harness assembly line, while the ceiling material 101 is first wound around the vehicle body assembly line. The second double-sided pressure-sensitive adhesive tapes T2 and T3 need to be adhesively fixed at required positions. As described above, it is necessary to pre-adhere and fix the first and second double-sided adhesive tapes T2 and T3 to the ceiling material 101 in the automobile assembly line. At that time, the first and second double-sided adhesive tapes T2 and T3 are attached. The position needs to be positioned.

  Furthermore, the second and third double-sided adhesive tapes T2 that are adhesively fixed to the ceiling material 101 at the positions corresponding to the single-sided adhesive tapes T1 wound around the wire harness 100 in the lengthwise direction, Although it is necessary to adhere to T3, there exists a possibility that it may adhere to the 2nd, 3rd double-sided adhesive tape T2, T3 of the position shifted in the length direction. In this way, when the positional deviation occurs between the wire-side adhesive tape T1 and the corresponding vehicle-side adhesive tape T1, T3, it is necessary to peel off the adhesive and start over, which is troublesome. is there.

  The present invention eliminates the need for attaching the adhesive tape on the vehicle harness side of the attachment of the wire harness side adhesive tape and the vehicle side adhesive tape. If the adhesive tape is previously attached to the wire harness side, An object is to enable the wire harness to be adhesively fixed to the required position via the adhesive tape.

  In order to solve the above-mentioned problems, as a first invention, a required portion in the length direction of the wire harness is arranged on one side of the length direction of the single-sided adhesive tape in a direction orthogonal to the length direction of the adhesive tape. A wire harness clamping / fixing portion that is folded back from the tip of the one side and is adhesively fixed by sandwiching the wire harness, and is folded back from the tip of the other side in the length direction of the adhesive tape so that both surfaces are non-adhesive surfaces A wire harness tape mounting structure is provided in which a peeling start portion is provided, an exposed adhesive surface is provided between the wire harness clamping and fixing portion and the peeling start portion, and the exposed adhesive surface is adhesively fixed to a material to be fixed. doing.

As described above, in the present invention, the single-sided adhesive tape is simply attached to the wire harness in advance, and the adhesive surface of the single-sided adhesive tape is not exposed to the outside until the wire harness is fixed to the vehicle body panel or the like. . That is,
Until the single-sided adhesive tape attached to the wire harness is adhesively fixed to a material to be fixed such as a vehicle body panel, the exposed adhesive surface is wound around the outer peripheral surface made of the non-adhesive surface of the wire harness clamping / fixing portion, or the exposed adhesive The surface is folded to make the outer surface non-adhesive.
With this configuration, the adhesive surface of the adhesive tape is used as the inner surface side until it is conveyed from the assembly line of the wire harness to the assembly line of the automobile and a single-sided adhesive tape (hereinafter abbreviated as adhesive tape) is adhesively fixed to the material to be fixed. Since it is not exposed to, it can hold | maintain, without adhering to another member. Further, when the exposed adhesive surface of the adhesive tape is exposed to the outer surface in order to fix the wire harness to the vehicle body panel or the like, the exposed adhesive surface can be easily exposed to the outside by pulling the peeling start portion.

  A pair of adhesive tape attachment portions to the wire harness is provided continuously or close to a required position in the length direction, and one adhesive tape projects the exposed adhesive surface to the right side of the wire harness, and the other adhesive tape. Preferably, the exposed adhesive surface protrudes to the left side of the wire harness, and the exposed adhesive surface protruded to the left and right is adhesively fixed to the material to be fixed.

  Moreover, as 2nd invention, the length direction of a wire harness is orthogonal to the length direction of this 1st adhesive tape on the upper surface of the center part of the length direction of a long 1st adhesive tape consisting of a single-sided adhesive tape. The wire harness is clamped by adhering and fixing the wire harness between the first and second adhesive tapes, by attaching a short second adhesive tape made of single-sided adhesive tape to the upper surface of the wire harness. A fixing portion is provided, and a peeling start portion is provided that is folded back from both ends in the length direction of the first adhesive tape so that both surfaces become non-adhesive surfaces, and between the wire harness sandwiching fixing portion and the peeling start portions at both ends A wire harness tape mounting structure is provided in which a pair of left and right exposed adhesive surfaces is provided on the adhesive and the exposed adhesive surfaces are adhesively fixed to a material to be fixed.

  In the tape mounting structure according to the second aspect of the invention, since the first adhesive tape can be provided with a pair of left and right exposed adhesive surfaces projecting on both the left and right sides of the wire harness, the left and right sides are continuous in the length direction of the wire harness. It is not necessary to provide a pair of adhesive tape mounting portions that protrude from each other.

The adhesive tape of the second invention is configured such that the exposed adhesive surfaces on both the left and right sides sandwiching the wire harness clamping / fixing portion are folded back to make the outer surface a non-adhesive surface until the adhesive tape is adhesively fixed to the fixed material.
With this configuration, the adhesive surface of the adhesive tape is the inner surface until it is conveyed from the assembly line of the wire harness to the assembly line of the automobile and the adhesive tape is adhesively fixed to the material to be fixed such as the vehicle body panel, as in the first invention. Since it is not exposed to the outside as a side, it can be held without sticking to other members. Further, when the left and right exposed adhesive surfaces are exposed to the outer surface, the left and right exposed adhesive surfaces can be easily exposed to the outside by pulling the peeling start portions at the left and right ends.

In both of the first invention and the second invention, the attachment site of the adhesive tape to the wire harness corresponds to the fixing position of the wire harness to the material to be fixed.
Thereby, when the adhesive tape previously attached to the wire harness is adhesively fixed to a fixed material such as a ceiling material, the wire harness is fixed to a predetermined position of the fixed material with the adhesive tape.

  As described above, in both the first and second inventions, it is only necessary to previously attach the adhesive tape to the wire harness, and it is not necessary to attach another adhesive tape to the vehicle-side fixing material in advance. Also, by attaching the adhesive tape mounting position to the wire harness with the fixing position of the wire harness to the fixed material, simply fixing the adhesive tape attached to the wire harness to the fixed material, The wire harness can be fixed to a predetermined fixing position of the material to be fixed via an adhesive tape. Therefore, parts cost and work cost can be greatly reduced.

A single-sided adhesive tape 2 (hereinafter abbreviated as “adhesive tape 2”) is attached to the wire harness 1 in the longitudinal direction in advance, and the roof harness 1 is fixed to a predetermined position of the ceiling material 3 using the adhesive tape 2. ing. That is, another adhesive tape is not attached in advance to the ceiling material 3 side.

1 to 5 show a first embodiment.
1st Embodiment is embodiment of the said 1st invention, and the adhesive tape 2 to be used is only one kind of adhesive tape which consists of a single-sided adhesive tape used widely, as shown in FIG. The adhesive tape 2 is provided with an adhesive layer 2b only on the inner surface (one surface) of a vinyl tape body 2a, and the outer surface (other surface) has no adhesive layer and is a non-adhesive surface. Hereinafter, the one surface provided with the adhesive layer 2b of the adhesive tape 2 is referred to as an adhesive surface 2S1, and the other surface is referred to as a non-adhesive surface 2S2.

  The pressure-sensitive adhesive tape 2 made of the single-sided pressure-sensitive adhesive tape is preliminarily attached to a required location spaced in the length direction with respect to the wire harness 1 in the wire harness assembly line by the procedure shown in FIGS. In FIG. 3, the adhesive surface 2S1 of the adhesive tape 2 is shown in white, and the non-adhesive surface 2S2 is shown in diagonal lines.

First, as shown in FIG. 3A, the adhesive tape 2 is cut at a required length L1. The length L1 is about 10 times the diameter of the wire harness 1, but may be 5 times or more. On the adhesive surface 2S1 of the adhesive tape 2, the wire harness 1 is arranged on one side in the length direction X in parallel with the width direction Y orthogonal to the length direction X, and the outer periphery of the wire harness 1 is shown by the adhesive layer 2b. Fix the middle and lower half circumferences.
The attachment position (P1) of the adhesive tape 1 with respect to the length direction of the wire harness 1 is a position corresponding to the position where the wire harness 1 is fixed to the ceiling material 3. The attachment position (P1) is specified in the work instruction sheet, and the worker confirms the attachment position while viewing the work instruction sheet and attaches it to the wire harness 1.

  Next, as shown in FIG. 3 (B) and FIG. 4 (A), the adhesive tape 2 is folded in half so as to sandwich the wire harness 1 from one end 2e in the length direction on the side where the wire harness 1 is disposed. The adhesive layer 2b on the inner surface (lower surface) of the folded piece 2c is fixed to the upper half periphery of the wire harness 1 in the figure, and the adhesive layer 2b at the tip of the folded piece 2c is not folded on the adhesive layer 2b. It adheres repeatedly. In this way, the length L2 of the wire harness is clamped and fixed with the peeling portion 10b that is fixed to the adhesive layer 2b so that the wire harness 1 is clamped between the adhesive layers 2b and is not easily separated. Part 10 is provided.

Further, the adhesive tape 2 is folded back from the other end 2f in the length direction of the adhesive tape 2 on the side where the wire harness 1 is not disposed, and the adhesive layer 2b of the folded piece is fixed to the adhesive layer 2b of the unfolded portion. And the short peeling start part 11 of length L3 which does not separate easily is provided.
Thereby, as shown in FIG. 3 (B), the wire harness sandwiching and fixing portion 10 and the peeling start portion 11 in which the outer surfaces of both the front and back surfaces are all non-adhesive surfaces 2S2 are provided at both ends in the length direction of the adhesive tape 2, An exposed adhesive surface 12 is provided in which the adhesive surface 2S1 having a length L4 is exposed to the outside. The length L4 of the exposed adhesive surface 12 is equal to or greater than the outer peripheral dimension of the wire harness 1.

  Next, as shown in FIGS. 3 (C) and 4 (B), the exposed adhesive surface 12 is wound around the outer periphery of the wire harness clamping / fixing portion 10 in a spiral shape. The exposed adhesive surface 12 that becomes the inner peripheral side in the wound state adheres to the outer peripheral surface of the non-adhesive surface 2S2 of the wire harness clamping and fixing portion 10. Even if it is going to wind the isolation start part 11 of the front end side, since the inner peripheral surface is the non-adhesive surface 2S2, it does not adhere to the non-adhesive surface of the outer peripheral surface of the wire harness clamping and fixing unit 10 and protrudes to the outer periphery.

  In the wire harness assembling process, the process is completed with the adhesive tape 2 shown in FIG. In this state, it is conveyed to the automobile assembly line, and the wire harness 1 is attached to the ceiling material 3 shown in FIG.

The terminal position of the wire harness 1 is positioned. Therefore, the position of the adhesive tape 2 attached in advance to the wire harness 1 is located at a place set as a position where the wire harness 1 is fixed to the ceiling material 3.

  In the vehicle mounting process of the wire harness, as shown in FIG. 3 (D), the worker pulls the peeling start portion 11 so as to be in the same state as in FIG. 3 (B). Pull out to the outside.

  Next, as shown in FIG. 1, the exposed adhesive surface 12 of the adhesive tape 2 is disposed toward the wire harness attachment surface 3 f of the ceiling material 3, and the exposed adhesive surface 12 is pressed against the ceiling material 3 to be adhesively fixed. At that time, as described above, since the adhesive tape 2 is attached in advance to the place where the wire harness 1 is fixed to the ceiling material 3, the adhesive tape 2 attached to the wire harness 1 is only adhesively fixed to the ceiling material 3. Thus, the wire harness 1 can be fixed via the adhesive tape 2 at the set position of the ceiling material 3.

The winding of the adhesive tape 2 around the wire harness 1 and the fixing to the ceiling material 3 with the adhesive tape 2 are specifically performed as shown in FIGS.
That is, the exposed adhesive surface 12 and the peeling start portion 11 of the adhesive tape 2 are not projected only on one side in the width direction orthogonal to the length direction of the wire harness 1 (for example, the left side of the wire harness 1). A pair of adhesive tape mounting portions are provided at positions that are continuous in the length direction of 1 or close to each other, one is an adhesive tape mounting portion A with the exposed adhesive surface 12 protruding on the left side, and the other is the exposed adhesive surface 12 on the right side. The adhesive tape mounting part B is made to protrude.
Thereby, the adhesive tape 2 is fixed to the ceiling material 3 on both the left and right sides of the wire harness 1, and the wire harness 1 is stably held on the ceiling material 3.

  As described above, the adhesive tape 2 attached in advance to the wire harness 1 can be used to fix the vehicle-side ceiling material 3 at a predetermined position. Therefore, it is not necessary to cross and cross-bond another double-sided pressure-sensitive adhesive tape to the ceiling material as in Patent Document 1, and the cost and the number of work of the pressure-sensitive adhesive tape can be greatly simplified.

FIG. 6 shows a modification of the first embodiment.
