The X direction and the Y direction shown in FIG. 6 coincide with the X direction and the Y direction shown in FIG. 5, and the Z direction shows a direction penetrating upward in FIG. Note that FIG. 6 is an explanatory diagram schematically shown, and therefore the sizes, positional relationships, and the like of the various structures in FIG. 6 are not accurately illustrated.

  Hereinafter, with reference to FIG.5 and FIG.6, the protection method of the wire harness 30 by the UV hardening sheet 2 of Embodiment 2 is demonstrated.

  First, the UV cured sheet 2 of Embodiment 2 shown in FIG. 5 is prepared in a state before ultraviolet irradiation.

  After that, the plurality of fold lines 21 are folded so that the UV curable sheet 2 is convex in different directions (one is in the + Z direction and the other is in the −Z direction) at the adjacent fold lines 21 and 21. Thus, the zigzag accordion-shaped UV cured sheet 2 is obtained as in the case of the first embodiment shown in FIG.

  At this time, as in the first embodiment, a wire harness penetration area, which is a space area into which the wire harness 30 can be inserted, is formed by the wire harness penetration opening 12a of each unit protection surface 2a.

  And in the several unit protection surface 2a, after inserting the wire harness 30 in the wire harness through-hole 12a, disperse | distributing a part of electric wire bundle of the wire harness 30 from the slit part 12b, after Embodiment 1 shown in FIG. Similarly to the case, the entire UV cured sheet 2 is slightly stretched in the X direction to set the final bellows form.

  Then, as shown in FIG. 6, it completes by attaching the connector 31 to the edge part of the wire harness 30, etc. FIG. FIG. 5 shows a case where the XY plane is the installation surface. Therefore, the distance from the installation surface to the wire harness 30 can be secured by the plurality of unit protection surfaces 2a, and the wire harness 30 can be protected.

  As described above, in the UV curable sheet 2 according to the second embodiment, the wire harness is set along the Y direction (+ Y direction) which is an extension direction from each slit portion 12b of each of the plurality of unit protective surfaces 2a after being set in the bellows shape. 30 can be inserted, and finally the wire harness 30 can be disposed through the wire harness through-hole 12a.

  Accordingly, the wire harness 30 is held by the plurality of unit protection surfaces 2a while holding the wire harness 30 in a form in which the wire harness penetration ports 12a are penetrated in the plurality of unit protection surfaces 2a of the UV curable sheet 2 in a cured state. The outer peripheral region can be protected from the outside.

  As a result, the UV curable sheet 2 according to the second embodiment obtains the UV curable sheet 2 capable of protecting various wire harnesses 30 in various spaces at a relatively low cost, like the UV curable sheet 1 according to the first embodiment. There is an effect that can be.

  Further, in the second embodiment, the UV curable sheet 2 having the bellows shape is inserted into the wire harness through-hole 12a by inserting the wire harness 30 from the slit portions 12b of each of the plurality of unit protective surfaces 2a along the Y direction. Since the harness 30 can be inserted, there is an effect that the insertion work of the wire harness 30 into the wire harness through-hole 12a can be performed relatively easily.

  Furthermore, since the formation width DB2 of the slit portion 12b in the X direction which is the formation width direction is set narrower than the formation width DA2 in the X direction of the wire harness through-hole 12a, the wire harness 30 is inserted into the wire harness through-hole 12a. It can prevent reliably that the wire harness 30 moves to the slit part 12b again from the wire harness penetration port 12a after doing.

<Embodiment 3>
FIG. 7 is a plan view showing the configuration of a UV cured sheet according to Embodiment 3 of the present invention. As shown in the figure, the UV curable sheet 3 is composed of a plurality of unit protective surfaces 3a (3a1, 3a2) formed continuously in the X direction. The plurality of unit protective surfaces 3a include a plurality of paired unit protective surfaces 3a1 and 3a2 adjacent to each other.

  Each of the plurality of unit protective surfaces 3a (3a1, 3a2) has a substantially square shape, and has a circular wire harness through-hole 13a in the central region.

  Similar to the UV curable sheets 1 and 2, the UV curable sheet 3 is provided between adjacent unit protective surfaces 3a (3a1) and 3a (3a2) and includes a plurality of fold lines 21 each of which can be folded along the Y direction. In addition.

  Furthermore, a part of the wire harness through-hole 13a is used as a connecting portion 13c, and extends from the connecting portion 13c in the X direction (the unit protective surface 3a1 is the -X direction and the unit protective surface 3a2 is the + X direction). A slit portion 13b is further provided so as to open the side where the fold line 21 exists.

  That is, each of the pair of unit protective surfaces 3a1 and 3a2 is an opening formed by a slit portion 13b provided to face the fold line 21 in the center and a wire harness through-hole 13a connected by the slit portion 13b and the connecting portion 13c. Part 13 is provided.

  And formation width DB3 of the slit part 13b in the Y direction which is the formation width direction of the slit part 13b is set narrower than formation width DA3 (diameter) in the Y direction of the wire harness through-hole 13a.

  The UV curable sheet 3, like the UV curable sheets 1 and 2, zigzags by folding a plurality of fold lines 21 so that different directions are convex between the adjacent fold lines 21 and 21 before ultraviolet irradiation. Shaped bellows form is feasible.

  Therefore, the wire harness 30 can be protected similarly to the UV cured sheet 2 of the second embodiment shown in FIGS. 5 and 6. However, the insertion method of the wire harness 30 into the wire harness through-hole 13a is slightly different.

  That is, after inserting the wire harness 30 into the wire harness through-hole 13a along the Z direction (− direction) while partially dispersing the wire bundle of the wire harness 30 from the slit portion 13b in the plurality of unit protection surfaces 3a1 and 3a2. As in the case of the first embodiment shown in FIG. 3, the entire UV cured sheet 3 is slightly stretched in the X direction to set the final bellows form.

  Subsequently, the UV curable sheet 3 is irradiated with ultraviolet rays so that the UV curable sheet 3 is cured and fixed in the final bellows form.

  Then, it completes by attaching the connector 31 to the edge part of the wire harness 30, etc. like the UV hardening sheet 2 shown in FIG.

  As described above, in the UV curable sheet 3 of the third embodiment, after setting the bellows form, the wire harness 30 is inserted along the Z direction which is the extending direction from each slit portion 13b of the plurality of unit protection surface pairs 3a. And finally, the wire harness 30 can be inserted into the wire harness through-hole 13a.

  Therefore, a plurality of unit protective surface pairs 3a are held while the wire harness 30 is held in a form in which the wire harness through holes 13a of the plurality of unit protective surfaces 3a (3a1, 3a2) of the UV cured sheet 3 in a cured form are passed. The outer peripheral area of the wire harness 30 can be protected from the outside by each.

  Therefore, the UV curable sheet 3 can be made relatively inexpensive as the UV curable sheet 3 capable of protecting various wire harnesses 30 in various spaces, like the UV curable sheets 1 and 2 of the first and second embodiments. There is an effect that can be obtained.

  Further, in the third embodiment, the UV curable sheet 3 having a bellows shape is inserted into the wire harness through-hole 13a by inserting the wire harness 30 along the Z direction from the slit portions 13b of the plurality of unit protective surfaces 3a1 and 3a2. Since the wire harness 30 can be penetrated into the wire harness 30, the wire harness 30 can be penetrated relatively easily.

  Furthermore, since the formation width DB3 of the slit portion 13b in the formation width direction which is the Y direction is set to be narrower than the formation width DA3 of the wire harness through-hole 13a, the wire harness after inserting the wire harness 30 into the wire harness through-hole 13a. It can prevent reliably that 30 moves to the slit part 13b again from the wire harness through-hole 13a.

  Each of the plurality of unit protection surfaces 4a has a substantially square shape, and has a circular wire harness through hole 14a in the central region.

  Similar to the UV curable sheets 1 to 3, the UV curable sheet 4 further includes a plurality of fold lines 21 that are provided between the adjacent unit protective surfaces 4 a and 4 a and can be folded along the Y direction.

  Furthermore, a part of the wire harness through-hole 14a is used as a connecting portion 14c and extends from the connecting portion 14c in the Y direction (-Y direction) as an extension direction so that one side of each unit protection surface 4a is opened. The slit portion 14b is further provided. That is, each unit protection surface 4a has the opening part 14 which consists of the wire harness penetration port 14a and the slit part 14b which were connected by the connection part 14c.

  And the minimum formation width DB41 in the connection part 14c of the slit part 14b in the X direction which is the formation width direction of the slit part 14b is set sufficiently narrower than the formation width DA3 of the wire harness through-hole 14a. Furthermore, the formation width of the slit portion 14b has a taper shape that becomes wider from the minimum formation width DB41 in the -Y direction that is the extension direction, and finally has the same maximum formation width DB42 (the same as the formation width DA4 of the wire harness through-hole 14a). Set to a slightly narrow width).

  Like the UV curable sheets 1 to 3, the UV curable sheet 4 is zigzag by folding a plurality of fold lines 21 so that the opposite directions are convex between the adjacent fold lines 21 and 21 before ultraviolet irradiation. Shaped bellows form is feasible.

  Therefore, the wire harness 30 can be protected in substantially the same manner as the UV cured sheet 2 of the second embodiment shown in FIGS.

  That is, after inserting the wire harness 30 into the wire harness through-hole 14a while partially dispersing the wire bundle of the wire harness 30 along the Y direction from the slit portion 14b in the plurality of unit protection surfaces 4a, as shown in FIG. As in the case of the first embodiment, the entire UV cured sheet 4 is slightly stretched in the X direction to set the final bellows form.

  Subsequently, the UV curable sheet 4 is irradiated with ultraviolet rays so that the UV curable sheet 4 is cured and fixed in the final bellows form.

  As described above, in the UV curable sheet 4 of the fourth embodiment, after the bellows shape is set, the Y direction (the insertion direction is the + Y direction) that is an extension direction from each slit portion 14b of the plurality of unit protection surfaces 4a. The wire harness 30 can be inserted in the wire harness through-hole 14a along.

  Therefore, while holding the wire harness 30 in a form in which the wire harness through-holes 14a of the plurality of unit protection surfaces 4a of the cured UV cured sheet 4 are penetrated, the plurality of unit protection surfaces 4a respectively The outer peripheral region can be protected from the outside.

  As a result, the UV curable sheet 4 is relatively inexpensive as the UV curable sheet 4 capable of protecting various wire harnesses 30 in various spaces, like the UV curable sheets 1 to 3 of the first to third embodiments. There is an effect that can be obtained.

  Further, in the fourth embodiment, the UV curable sheet 4 having the bellows form is inserted into the wire harness through-hole 14a by inserting the wire harness 30 along the Y direction from the slit portions 14b of the plurality of unit protective surfaces 4a. Since the harness 30 can be penetrated, the wire harness 30 can be penetrated relatively easily.

  Furthermore, since the minimum formation width DB41 of the slit portion 14b in the formation width direction which is the Y direction is set sufficiently narrower than the formation width DA3 of the wire harness through-hole 14a, the wire harness 30 is inserted into the wire harness through-hole 14a. Later, the wire harness 30 can be reliably prevented from moving again from the wire harness through-hole 14a to the slit portion 14b.

  In addition, the slit portion 14b has a tapered shape in which the formation width in the X direction, which is the formation width direction, becomes wider from DB41 to DB42 as it goes from the connecting portion 14c in the Y direction (-Y direction) that is the extension direction. The insertion process of the wire harness 30 along the Y direction from the slit portion 14b into the wire harness through-hole 14a can be performed more easily.

  Therefore, the wire harness 30 can be protected in substantially the same manner as the UV cured sheet 2 of the second embodiment shown in FIGS.

  That is, after inserting the wire harness 30 into the wire harness through-hole 15a while partially dispersing the wire bundle of the wire harness 30 from the slit portion 15b in the plurality of unit protection surfaces 5a, the wire harness 30 of the first embodiment shown in FIG. Similarly to the case, the entire UV cured sheet 5 is slightly stretched in the X direction to set the final bellows form.

  Subsequently, the UV cured sheet 5 is irradiated with ultraviolet rays so that the UV cured sheet 5 is cured and fixed in the final bellows form.

  As described above, in the UV curable sheet 5 according to the fifth embodiment, after the bellows shape is set, the Y direction (the insertion direction is the + Y direction) that is an extension direction from the slit portions 15b of the plurality of unit protective surfaces 5a. The wire harness 30 can be inserted in the wire harness through-hole 15a along.

  Therefore, the outer periphery of the wire harness 30 is retained by each of the plurality of unit protective surfaces 5a while holding the wire harness 30 in a form in which the wire harness through hole 15a is penetrated in each unit protective surface 5a of the cured UV cured sheet 5. The area can be protected from the outside.

  As a result, the UV curable sheet 5 is relatively inexpensive as the UV curable sheet 5 capable of protecting various wire harnesses 30 in various spaces, like the UV curable sheets 1 to 4 of the first to fourth embodiments. There is an effect that can be obtained.

  Further, in the fifth embodiment, the UV curable sheet 5 having the bellows form is inserted into the wire harness through-hole 15a by inserting the wire harness 30 along the Y direction from the slit portions 15b of the plurality of unit protective surfaces 5a. Since the harness 30 can be inserted, the wire harness 30 can be penetrated relatively easily.

  Further, in the fifth embodiment, the connecting portion 15c is provided with a predetermined distance ΔD shifted from the center position 15x of the wire harness through-hole 15a in the X direction, which is the formation width direction. Therefore, the wire harness 30 is placed in the wire harness through-hole 15a. After insertion, the possibility that the wire harness 30 moves from the wire harness through-hole 15a to the slit portion 15b can be effectively suppressed.

<Others>
Since the UV curable sheets 1 to 5 of Embodiments 1 to 5 have circular wire harness through-holes 11a to 15a on the unit protective surfaces 1a to 5a, respectively, the cross-sectional shape is circular. The necessary wire harness 30 can be protected with good stability.

  The embodiment described above may be modified so that the unit protective surfaces 1a to 5a have an elliptical wire harness through hole. In this case, there is an effect that the wire harness that needs to have an elliptical cross-sectional shape can be protected with good stability, for example, it is necessary to reduce the thickness of the wire harness in a predetermined direction.

  Moreover, in embodiment mentioned above, although it fixed in the bellows form regarding UV hardening sheet 1-5, the example which arrange | positions XY plane on an installation surface was shown, However, It is not limited to this, XZ plane or YZ plane Of course, the above-described effects can be obtained even if the wire harness 30 is arranged on the installation surface, and the wire harness 30 can be protected from the interference on the installation surface.

  Moreover, in embodiment mentioned above, although the wire harness 30 which consists of an electric wire bundle exposed as a linear body was shown, the wire harness by which the electric wire bundle was tape-wrapped previously may be sufficient.
