  However, since the conventional wire harness 501 has fixed the plurality of clamps 509 one by one by tape winding, it is difficult to manually remove the clamp 509 by pulling it from the vehicle. For this reason, the hook 507 is hooked on the eye 505 or the like and peeled off by a large traction machine such as a crane truck. However, disassembly using such a large traction machine takes time for disassembly and is easy. There was a problem that the dismantling property was low, such as not being dismantled and the wire harness 501 after being dismantled being destroyed and not becoming homogeneous.

  The present invention has been made in view of the above situation, and the object thereof is to attach a wire harness with a clamp and a wire harness with a clamp that can be easily detached without using a large traction machine when the vehicle is disassembled. The object is to provide a method for removal from the body.

The above object of the present invention is achieved by the following configuration.
(1) A wire harness is sheathed by a single-sided self-adhesive sheet that holds a plurality of clamps at a predetermined pitch in accordance with the mounting position of the body to be attached, and is drilled in the single-sided self-adhesive sheet to pass through the support shaft of the clamp. In the sheet hole, a slit in a direction perpendicular to the longitudinal direction of the long pedestal portion of the clamp held between the single-sided self-adhesive sheets is continuously formed. Harness.

According to this wire harness with a clamp, the single-sided self-adhesive sheet that sheathes the wire harness holds the clamp. That is, the pedestal portion sandwiched directly or indirectly between the single-sided self-adhesive sheets in the state where the longitudinal direction is perpendicular to the slits cannot be removed from the slits, and the clamp is held by the single-sided self-adhesive sheet. A wire harness is attached to a to-be-attached body via a single-sided self-adhesive sheet because a clamp is latched by a to-be-attached body.
When the single-sided self-adhesive sheet and the clamp are relatively rotated and the longitudinal direction of the pedestal matches the slit of the single-sided self-adhesive sheet, the pedestal can be removed from the slit, and the clamp is detached from the single-sided self-adhesive sheet. Thereby, the wire harness can be detached from the attached body together with the single-sided self-adhesive sheet while the clamp is left on the attached body.

(2) A method of removing a wire harness with a clamp from a clamped body that removes a wire harness covered by a single-sided self-adhesive sheet holding the clamp from a clamp locked in a clamp hole of the mounted body, The single-sided self-adhesive sheet for inserting the longitudinal axis of the long pedestal portion of the clamp held between the single-sided self-adhesive sheet by rotating the single-sided self-adhesive sheet and the clamp relative to each other. The single-sided self-adhesive sheet is pulled and the wire harness is removed from the attached body together with the single-sided self-adhesive sheet after being matched with the slit formed continuously in the sheet hole formed in the sheet. How to remove from the mounting body.

  According to this method of removing the wire harness with clamp from the attached body, the single-sided self-adhesive sheet in the vicinity of the clamp is grasped together with the wire harness, rotated relative to the clamp, and the slit is made to coincide with the longitudinal direction of the base portion of the clamp. In this state, when the single-sided self-adhesive sheet is pulled, the pedestal portion held by being directly or indirectly sandwiched by the single-sided self-adhesive sheet comes out of the slit, and the single-sided self-adhesive sheet is locked to the attached body. Remove from the clamp. Thereby, the wire harness can be detached from the attached body together with the single-sided self-adhesive sheet while leaving the clamp on the attached body.

  According to the wire harness with a clamp and the method for removing the wire harness with a clamp from the attached body according to the present invention, it is easy to remove the wire harness from the attached body. As a result, when the vehicle is disassembled, the wire harness can be easily removed without using a large traction machine.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a wire harness with a clamp according to an embodiment of the present invention.
The wire harness with clamp 11 has a wire harness 17 covered with a single-sided self-adhesive sheet 15 holding a plurality of clamps 13 at a predetermined pitch. The wire harness 17 is composed of a plurality of trunk lines 19 and a branch section 21 branched from the trunk section 19, and the terminal section 19a of the trunk section 19 and the terminal section 21a of the branch section 21 are connected to a vehicle (not shown). A connector 23 connected to the mounted auxiliary machine or the like is attached.

As shown in FIG. 4, the single-sided self-adhesive sheet 15 used in the present embodiment can bond its own adhesive surfaces (back surfaces) to each other by self-adhesion. That is, it is possible to simply apply the adhesive surfaces (rear surfaces) together without using glue or a binding tape. The single-sided self-adhesive sheet 15 has a surface material 22 laminated on the surface of a sheet base material 28 made of PP (polypropylene) foam, and a special pressure-sensitive adhesive layer 25 laminated on the back surface. Kraft paper, liner board, PET (polyethylene terephthalate) film, PP film, non-woven fabric, etc. can be used for the surface material 22. Tensile strength is 49 N / cm width in the vertical direction, 23 N / cm width in the horizontal direction (according to JIS K-6767), and tear strength is 7.8 N in the vertical direction and 6.8 N in the horizontal direction (JIS K- 6767), water vapor permeability is 0.0052 g / cm ² · 24 hrs (FS-101B), and initial adhesive strength is 2.5 N / cm width (T-type peel test). As this single-sided self-adhesive sheet 15, for example, Cro-nel (registered trademark) manufactured by Crowell, Inc. of the United States can be used.

FIG. 2 is a perspective view of the clamp 13 shown in FIG.
The clamp 13 held by the wire harness with clamp 11 has an oval base 29 having convex pieces 27 at both ends in the longitudinal direction. In addition, the pedestal portion 29 is not limited to an oval shape, but may be another long shape such as a rectangle as long as the length in the longitudinal direction is longer than the short direction (width direction). Although the convex piece 27 may be omitted, the convex piece 27 substantially enlarges the area of the seal surface pressure generating portion 29a in the pedestal portion 29 so that the holding force of the clamp 13 with respect to the single-sided self-adhesive sheet 15 is increased. Can be increased. A support shaft 31 is erected on the seal surface pressure generating portion 29a, which is one surface of the pedestal portion 29, and a pair of elastic locking claws 33 are formed at the tip thereof.

3 is an enlarged view of a portion C in FIG. 1, and FIG. 4 is a view taken in the direction of arrows EE in FIG.
In the present embodiment, the single-sided self-adhesive sheet 15 includes a first single-sided self-adhesive sheet material 35 and a second single-sided self-adhesive sheet material 37 (see FIGS. 5 and 6). The first single-sided self-adhesive sheet material 35 is a sheet in which a special adhesive layer 25 is laminated on the back side, and the outer shape is pre-wired except for the free terminal portions 19a and 21a in the vicinity of the connector 23 other than the F portion in FIG. The harness 17 is formed in a path shape. Similarly to the first single-sided self-adhesive sheet material 35, the second single-sided self-adhesive sheet material 37 is a sheet in which the special adhesive layer 25 is laminated on the back surface, and the first single-sided self-adhesive sheet material 35 and the adhesive surface It is formed into a shape in which the (back) surfaces are combined. A sheet hole 39 is formed at a predetermined position of the second single-sided self-adhesive sheet material 37. The elastic locking claw 33 and the support shaft 31 of the clamp 13 are inserted into the sheet hole 39. The second single-sided self-adhesive sheet material 37 having the clamp 13 inserted through the sheet hole 39 constitutes a clamp / sheet assembly.
The outer shapes of the first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37 are not limited to the parts such as the main line part 19 and the branch part 21, but can be varied depending on the purpose and application. Molded.
As shown in F part of FIG. 1, the connector 23 and the terminal part 21 a are made rigid by forming the single-sided self-adhesive sheet 15 into a shape that collectively encloses the connector 23 and the terminal part 21 a of the wire harness 17. Or the terminal portion 21a can be protected from contact with the mounted body 41 or the like. Of course, the single-sided self-adhesive sheet 15 can also be formed in a shape that collectively encloses all the connectors 23 and the terminal portions 19a, 21a of the wire harness 17.

  In the clamp 13, the support shaft 31 and the elastic locking claw 33 are inserted into the sheet hole 39 of the second single-sided self-adhesive sheet material 37. Therefore, in C part and D part shown in FIG. 1, the pedestal part 29 is directly sandwiched and held between the second single-sided self-adhesive sheet material 37 and the first single-sided self-adhesive sheet material 35 ( (See FIG. 4). The pedestal portion 29 sandwiched between the second single-sided self-adhesive sheet material 37 and the first single-sided self-adhesive sheet material 35 is not directly adhered to the special adhesive layer 25 of these single-sided self-adhesive sheet materials 35 and 37, and therefore is constant. When the moment is applied, rotation about the support shaft 31 becomes possible.

  The clamp 13 is held in different forms. For example, the wire harness 17 and the clamp 13 can be vertically stacked and attached. A part and B part shown in FIG. 1 correspond to this attachment part. In this case, the pedestal 29 is indirectly sandwiched between the first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37 via the wire harness 17 in the clamp 13. Alternatively, the position of the seat hole 39 may be shifted (offset) from the wiring position X of the wire harness 17, and the wire harness 17 and the clamp 13 may be mounted side by side. In this case, as described above, the pedestal portion 29 of the clamp 13 is directly sandwiched between the first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37. Since the clamp 13 is offset from the wiring position X of the wire harness 17 (a separation distance indicated by Δt in FIG. 1), the height of the clamp 13 and the height of the wire harness 17 are not integrated, The mounting height of the wire harness 17 can be kept low. The C part and D part shown in FIG. 1 correspond to this attachment part.

  In the single-sided self-adhesive sheet 15 of the present embodiment, a configuration using two first single-sided self-adhesive sheet materials 35 and a second single-sided self-adhesive sheet material 37 will be described. The wire harness 11 is not limited to this, and the first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37 can be used as long as the wire harness 17 is packaged by a single-sided self-adhesive sheet. Even if the wire harness 17 is sandwiched between a single unit and the adhesive surfaces are bonded together, the same action and effect can be obtained.

  The support shaft 31 of the clamp 13 inserted through the sheet hole 39 is preferably thinner than the diameter of the sheet hole 39 so that the pitch can be adjusted. In this case, as shown in FIGS. 4 and 8, a gap 38 is generated between the sheet hole 39 and the support shaft 31, so that the clamp 13 can move with respect to the sheet hole 39, and fine adjustment of the clamp pitch, etc. Is possible. The sheet hole 39 may be a long hole that is long in the pitch adjusting direction. However, the basic position of the sheet hole 39 is integrally positioned by pressing or the like when the outer shape of the second single-sided self-adhesive sheet material 37 is formed. As a result, the clamp position is positioned with extremely high accuracy compared to the conventional manual attachment of the clamp 13.

  In this way, the wire harness with clamp 11 is wire harnessed by the single-sided self-adhesive sheet 15 that holds the plurality of clamps 13 at a predetermined pitch in accordance with the mounting position of the mounted body 41 (see FIG. 4) such as a body or a door. 17 will be packaged.

  By the way, in the sheet hole 39 formed in the single-sided self-adhesive sheet 15 through which the support shaft 31 of the clamp 13 is inserted, a slit 43 in a direction orthogonal to the longitudinal direction of the pedestal 29 of the clamp 13 is provided, as shown in FIG. Are formed continuously. In the present embodiment, the slit 43 is a central position in the longitudinal direction of the pedestal portion 29, and a pair of slits are continuously formed in a direction orthogonal to the longitudinal direction. The slit 43 is a cut in which the slit base end 45 is opened to the sheet hole 39, and the sheet hole 39 can be enlarged by rolling the both side pieces 47 sandwiching the slit 43.

  Further, in the present embodiment, small slits 51 that are orthogonal to each other are formed continuously at the slit tip 49 of each slit 43. That is, the slits 43 are each formed in a T shape. The small slits 51 make it easier for the side pieces 47 to bend in the slits 43, and as a result, the pedestal 29 is easily detached.

  In the state shown in FIG. 3 in which the small slit 51 and the distal end side (slit distal end portion 49 side) of the slit 43 are attached with the clamp 13 in a direction in which the longitudinal direction of the pedestal portion 29 is orthogonal to the slit 43, single-sided self-adhesion. The single-sided self-adhesive sheet materials 35 and 37 of the sheet 15 are joined and not opened by the special adhesive layer 25.

Next, a method for assembling the clamped wire harness 11 will be described with reference to FIGS.
FIG. 5 is an exploded view of the wire harness 11 with a clamp shown in FIG. 1, and FIG. 6 is an exploded cross-sectional view of a surface in a direction perpendicular to the wire harness 17 in the vicinity of the clamp 13 in part A shown in FIG.
In order to assemble the wire harness 11 with a clamp, first, the second single-sided self-adhesive sheet 37 is laid on a work table or the like. The second single-sided self-adhesive sheet material 37 has the special adhesive layer 25 on top. The wire harness 17 is placed on the second single-sided self-adhesive sheet material 37 as an underlay. The clamp 13 is inserted through the sheet hole 39 of the second single-sided self-adhesive sheet material 37 in advance, but the clamp 13 may be inserted through the sheet hole 39 and assembled together with the wire harness 17 placed thereon.

  If the wire harness 17 is mounted, the 1st single-sided self-adhesive sheet material 35 will be covered from the top. The first single-sided self-adhesive sheet material 35 has the special adhesive layer 25 facing down. The first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37 are pressure-bonded in a state where the wire harness 17 and the pedestal 29 of the clamp 13 are sandwiched. Thereby, a plurality of clamps 13 are attached at a predetermined pitch, and at the same time, the wire harness with clamp 11 in which the wire harness 17 is sandwiched and held by the single-sided self-adhesive sheet 15 is completed (see FIG. 1).

Next, the removal method from the to-be-attached body 41 of the wire harness 11 with a clamp which has the said structure is demonstrated.
7 is a plan view after rotation of the single-sided self-adhesive sheet of FIG. 3, FIG. 8 is a cross-sectional view taken along the line F-F of FIG. 7, and FIG.
It is desired that various parts can be easily removed from the vehicle body (highly easy to disassemble) when the vehicle is disassembled. The wire harness 17 is no exception. In the wire harness with clamp 11 having the above configuration, the single-sided self-adhesive sheet 15 that sheathes the wire harness 17 holds the clamp 13. And the elastic latching claw 33 of the clamp 13 is latched by the to-be-attached body 41, and the wire harness 17 is attached to the to-be-attached body 41 via the single-sided self-adhesive sheet 15. FIG.

  For this reason, when the vehicle is disassembled, the single-sided self-adhesive sheet 15 in the vicinity of the clamp 13 is grasped together with the wire harness 17 and rotated relative to the clamp 13 and sandwiched between the single-sided self-adhesive sheet 15 as shown in FIGS. The slit 43 is aligned with the longitudinal direction of the oval pedestal portion 29 of the clamp 13 held in this manner. In this state, when the single-sided self-adhesive sheet 15 is pulled in the direction of arrow D, as shown in FIG. 8, both side pieces 47 of the second single-sided self-adhesive sheet material 37 are moved to the arrows U1, U2 by the pedestal 29 of the clamp 13. Each is beaten in the direction. Then, as shown in FIG. 9, the pedestal 29, which is directly held between the first single-sided self-adhesive sheet material 35 and the second single-sided self-adhesive sheet material 37, comes out of the slit 43, and the single-sided self-adhesive sheet 15 is disengaged from the clamp 13 locked to the mounted body 41. Thereby, the wire harness 17 is very easily detached from the attached body 41 together with the single-sided self-adhesive sheet 15 while leaving the clamp 13 on the attached body 41.

  Thus, by rotating the single-sided self-adhesive sheet 15 relative to the clamp 13 and aligning the slit 43 with the longitudinal direction of the pedestal part 29, the pedestal part 29 can come out of the slit 43, and from the single-sided self-adhesive sheet 15 The clamp 13 is released. The relative rotation of the single-sided self-adhesive sheet 15 and the clamp 13 not only rotates the single-sided self-adhesive sheet 15 relative to the clamp 13 attached to the attachment body 41 as described above, but also the first single-sided self-adhesive sheet 15. One-side self-adhesion is achieved by turning the exposed pedestal portion 29 by breaking the portion corresponding to the pedestal portion 29 of the adhesive sheet material 35, or picking the elastic locking claw 33 from the back side of the mounted body 41 and turning the clamp 13 The sheet 15 and the clamp 13 may be rotated relative to each other. By turning the elastic locking claw 33, it is possible to remove the attached body 41 from the back side. When the first single-sided self-adhesive sheet material 35 is torn and the pedestal portion 29 is exposed, the pedestal portion 29 is placed on the surface of the first single-sided self-adhesive sheet material 35 in order to make the position of the pedestal portion 29 easier to find. A mark indicating the position may be provided.

  Therefore, according to the wire harness 11 with a clamp and the method for removing the wire harness 11 with a clamp from the attached body 41 according to the present embodiment, the wire harness 17 can be easily detached from the attached body 41. As a result, when the vehicle is disassembled, the wire harness 17 can be easily detached from the vehicle body without using a large traction machine.
