The cylindrical high-rigidity portion 20 is arranged in the shape of an inverted rectangular prism and has a rectangular cross section.

The plate-shaped low-rigidity portion 10 is a substantially belt-shaped plate material that is longer in the longitudinal direction L than in the width direction W and has a predetermined thickness in the height direction H, and is arranged along the longitudinal direction L.
The cylindrical high-rigidity part 20 includes a bottom part 23 that is continuous with the plate-like low-rigidity part 10 in the longitudinal direction L, an upper part 21 arranged at a predetermined interval in the height direction H with respect to the bottom part 23, and an upper surface. The portion 21 and the bottom portion 23 are formed into a cylindrical shape with a substantially square cross section, with side portions 22 connecting in the height direction H at both ends in the width direction W.

The cylindrical high-rigidity portion 20 is formed to have approximately the same length as the plate-like low-rigidity portion 10 in the longitudinal direction L.
Further, the cylindrical high-rigidity portion 20 having a cylindrical shape with a substantially square cross section has higher rigidity than the plate-like low-rigidity portion 10. Specifically, the moment of inertia (section modulus) of the cylindrical high-rigidity portion 20 is higher than the moment of inertia (section modulus) of the plate-like low-rigidity portion 10 .

The protector 1 constructed in this manner is constructed by subjecting the unfolded sheet 100 to a bending process, as shown in FIG. 1(c).
To be more specific, the unfolded sheet 100 includes approximately band-shaped low-rigidity forming portions 110 extending in the longitudinal direction L arranged on both sides of the longitudinal direction L, and high-rigidity forming portions 110 disposed between the low-rigidity forming portions 110. 120.

The high-rigidity forming part 120 constituting the cylindrical high-rigidity part 20 has surface forming parts 121 arranged in parallel in the width direction W, each having the same length in the width direction W as the low-rigidity forming part 110. As described above, the surface forming portions 121 are arranged in parallel in a number equal to the number of surfaces of the cylindrical high-rigidity portion 20 having a cylindrical cross section plus one surface. The high-rigidity part forming part 120 of this embodiment, which constitutes the cylindrical high-rigidity part 20 having a substantially square cross section, is constructed by arranging five surface forming parts 121 in parallel in the width direction W.

In this embodiment, among the five surface forming sections 121 arranged in parallel in the width direction W, the center surface forming section 121 in the width direction W and the low rigidity section forming section 110 are continuous.
The high-rigidity portion forming portion 120 of the developed sheet 100 configured as described above is subjected to a bending process using the broken line shown in FIG. 1(c) as a fold line. The high-rigidity forming part 120, which has one more surface than the cylindrical high-rigidity part 20, is bent to have an annular cross-section, and the surface-forming parts 121 at both ends in the width direction W are overlapped.

In the unfolded sheet 100 in which the low-rigidity part forming part 110 is continuous with the surface forming part 121 at the center in the width direction W, in the bottom part 23 continuous with the plate-like low-rigidity part 10 and the top part 21 facing in the height direction H, The surface forming portions 121 are laminated and overlapped to form a superposed portion 20X (see FIG. 1(b)).

Note that the cylindrical high-rigidity portion 20 obtained by bending the high-rigidity portion forming portion 120 includes a fixing portion (not shown) at the end of the high-rigidity portion forming portion 120 to fix the cylindrical shape formed by bending the high-rigidity portion forming portion 120. Alternatively, the cylindrical shape may be fixed by welding, tape fixing, or the like.

The spread sheet 100 is a plate-shaped thermoplastic resin foam sheet having a predetermined thickness and formed into the above-described shape.
The density of the resin sheet constituting the unfolded sheet 100 is not particularly limited, but for example, it can prevent anisotropy in mechanical properties, that is, make the mechanical properties isotropic and improve the degree of freedom in designing the protector 1. In addition, in order to further improve the strength against stress in the WH direction of the wire harness housed in the protector 1, it is preferably 200 Kg/m ³ or more and 1000 Kg/m ³ or less, further improving the balance between lightness and mechanical strength. From the point of view of this, it is more preferably 300 Kg/m ³ or more and 600 Kg/m ³ or less, and particularly preferably 350 Kg/m ³ or more and 550 Kg/m ^{3 or} less.

The thickness of the thermoplastic resin foam sheet constituting the protector 1 is not particularly limited, but it can be used, for example, to improve bendability and mechanical strength, especially mechanical strength against stress in the WH direction of the wire harness housed in the protector 1. In terms of further improving the balance, the range is preferably 0.50 mm or more and 4.0 mm or less, and particularly preferably 1.0 mm or more and 2.5 mm or less. Further, a non-foamed layer may be formed on both sides or one side of the thermoplastic resin foamed sheet. That is, the thermoplastic resin foam sheet may have a structure including a foam layer and a non-foam layer formed on the foam layer. By forming the non-foamed layer on the surface of the thermoplastic resin foam sheet, the mechanical strength of the protector 1 is improved, and the protection performance of the wire harness WH accommodated is further improved. The thickness of the non-foamed layer is not particularly limited, and may be, for example, 10 μm or more and 100 μm or less.

Further, the cell number density of the foam layer of the thermoplastic resin foam sheet constituting the protector 1 is not particularly limited, and the lower limit value is 800 cells/cell in order to more reliably prevent anisotropy of mechanical properties. mm ³ or more is preferable, and 1000 pieces/mm ³ or more is particularly preferable. On the other hand, the upper limit of the bubble number density is, for example, 1010 cells/mm ³ or less, from the viewpoint of more reliably obtaining excellent mechanical strength.
In the protector 1 constructed by bending a resin sheet as described above, the top surface portion 21, side surface portion 22, and bottom surface portion 23 that constitute the plate-like low-rigidity portion 10 and the cylindrical high-rigidity portion 20 are configured in a plate shape.

The protector 1, which is constructed by forming the above-described spread sheet 100 into the above-described shape and bending the high-rigidity portion forming portion 120, is placed on a part of the wire harness WH in the longitudinal direction L.

Specifically, the cylindrical high-rigidity portion 20 that sheathes the wire harness WH is sheathed by inserting the wire harness WH into the cylindrical interior. On the other hand, the plate-like low-rigidity part 10 is exteriorized by fixing the plate-like low-rigidity part 10 and the cylindrical high-rigidity part 20 with a tape or band (not shown) along the wire harness WH. That will happen.

The protector 1, which is externally wrapped around a part of the wire harness WH in the longitudinal direction L as described above, is constituted by a resin sheet, and the cylindrical high-rigidity part 20 and the plate-like low-rigidity part 10, which have different cross-sectional rigidities, are continuous. The first effect is that it can accommodate various route regulations and protection modes.

Note that the cylindrical high-rigidity portion 20 that sheathes the wire harness WH is sheathed by inserting the wire harness WH into the cylindrical interior. On the other hand, the plate-like low-rigidity part 10 is exteriorized by fixing the plate-like low-rigidity part 10 and the cylindrical high-rigidity part 20 with a tape or band (not shown) along the wire harness WH. That will happen.

More specifically, the cylindrical high-rigidity portion 20 can form an exterior portion that requires route regulation and reliable protection of the wire harness WH. Moreover, an exterior part can be formed in which the direction in which the wire harness WH is installed can be changed while the plate-like low-rigidity part 10 regulates the route. Therefore, it is possible to support various protection modes depending on the required purpose and wiring route.

Specifically, since the cylindrical high-rigidity portion 20 is cylindrical, it surrounds the outer periphery of the wire harness WH that is inserted through the cylindrical high-rigidity portion 20, and since it is highly rigid, it can provide reliable protection and route regulation.
On the other hand, since the plate-shaped low-rigidity part 10 is plate-shaped, it can protect one direction with respect to the wire harness WH by extending it along the wire harness WH. Moreover, since the plate-like low-rigidity part 10 is plate-shaped, the plate-like low-rigidity part 10, which has a lower rigidity than the cylindrical high-rigidity part 20, may be curved in the thickness direction or You can easily change the direction of its extension by twisting it. Therefore, the straight plate-like low-rigidity part 10 may be placed along the wire harness WH, but the wire harness WH can be attached to the plate-like low-rigidity part 10 whose extending direction is changed by curving or twisting the wire harness WH. By aligning the wire harness WH, the plate-like low-rigidity portion 10 can not only protect the wire harness WH from one direction but also regulate the route of the wire harness WH.

Further, the cylindrical high-rigidity portion 20 is configured to have an annular cross-section and is cylindrical surrounding the wire harness WH, and the plate-like low-rigidity portion 10 is a planar body portion having at least one surface along the wire harness WH. . Therefore, the protector 1 can surround the wire harness WH in all directions with the cylindrical high-rigidity portion 20 having a cylindrical cross section, and can reliably protect the wire harness WH. In addition, the plate-like low-rigidity portion 10 can provide the second effect of being able to protect only a required direction while keeping the wire harness WH along the wiring direction.

In addition, since the cylindrical high-rigidity portion 20 is formed with a polygonal cross section by bending a resin sheet, the third effect is that it can improve its workability while ensuring sufficient cross-sectional rigidity. can play.

In addition, the cylindrical high-rigidity portion 20 has an overlapping portion 20X in which the resin sheet overlaps on at least one side of the polygonal cross section formed by bending the resin sheet, and the plate-like low-rigidity portion 10 has an overlapping portion 20X in the polygonal cross-section formed by bending the resin sheet. Since the plate-shaped low-rigidity part 10 is connected to the bottom part 23 which is a non-overlapping part different from the overlapped part 20 The fourth effect of making it easier to change the installation direction of the wire harness WH can be achieved.

Further, the cylindrical high-rigidity portion 20 has a plurality of surfaces along the wire harness WH, and the plate-like low-rigidity portion 10 has fewer surfaces along the wire harness WH than the cylindrical high-rigidity portion 20. The fifth effect is that each of the plate-like low-rigidity part 10 and the cylindrical high-rigidity part 20 can be configured with a required rigidity depending on the mounting condition of the exterior part, the type of protection, etc.

Moreover, since the plate-like low-rigidity part 10 extends along the axial direction of the cylindrical high-rigidity part 20, a part of the linear wire harness WH can be reliably protected, and the wire harness The sixth effect is that the direction of the WH can be regulated, and the workability of the cylindrical high-rigidity portion 20 and the plate-like low-rigidity portion 10 can be improved.

In the protector 1 described above, a plate-like low-rigidity plate having approximately the same length as the cylindrical high-rigidity part 20 is provided on both sides of the cylindrical high-rigidity part 20 in the longitudinal direction L on one side Lf and on the other side Ls in the longitudinal direction. Although the plate-like low-rigidity parts 10 provided on one longitudinal side Lf and the other longitudinal side Ls of the cylindrical high-rigidity part 20 may have different lengths, or the plate-like low-rigidity parts 10 may have different lengths. 10 and the cylindrical high-rigidity portion 20 may have different lengths. Furthermore, the plate-like low-rigidity portion 10 may be provided only on one longitudinal side Lf or the other longitudinal side Ls of the cylindrical high-rigidity portion 20.

In the following description, components of the protector 1g that are the same as those of the protector 1 described above are given the same reference numerals and explanations thereof will be omitted, and components of the protector 1g that are different from those of the protector 1 will be described in detail.

In the protector 1 described above, the plate-like low-rigidity parts 10 were provided on both sides of the cylindrical high-rigidity part 20 in the longitudinal direction L, but the protector 1g has three cylindrical high-rigidity parts spaced apart from each other by a predetermined interval in the longitudinal direction L. 20, and a plate-like low-rigidity part 10 is arranged between the cylindrical high-rigidity parts 20 arranged in the longitudinal direction L.

As shown in FIG. 9, the developed sheet 100g constituting the above-mentioned protector 1g has high-rigidity forming portions 120 in which five surface forming portions 121 are arranged in parallel in the width direction W at predetermined intervals in the longitudinal direction L. The low-rigidity portion forming portion 110 is arranged between the high-rigidity portion forming portions 120. Among the five low-rigidity forming parts 110 disposed between the high-rigidity forming parts 120, the low-rigidity forming part 110 is continuous with the surface forming part 121 at the center in the width direction W.

The cylindrical high-rigidity portion 20 is constructed by bending the high-rigidity portion forming portion 120 of the developed sheet 100g constructed in this way along the folding line shown by the broken line in FIG. 20X.

Thereby, the first effect of the protector 1g of the eighth embodiment, which is that the support rigidity of the plate-like low-rigidity portion 10 can be ensured, can be achieved.

Furthermore, as described above, since the cylindrical high-rigidity part 20 is cylindrical, it surrounds the outer periphery of the wire harness WH that is inserted through it, and is highly rigid, so it is possible to perform reliable protection and route regulation. can.
On the other hand, since the plate-like low-rigidity part 10 is plate-shaped, it can protect one direction with respect to the wire harness WH by being placed along the wire harness WH, and the plate-like low-rigidity part 10 can be protected in the thickness direction. The direction of extension can be easily changed by bending the plate or twisting it in the thickness direction.

Therefore, by bending or twisting the plate-like low-rigidity portion 10 disposed between the cylindrical high-rigidity portions 20, the wire harness WH is laid along the plate-like low-rigidity portion 10 whose extension direction is changed. By doing so, the orientation and arrangement of the cylindrical high-rigidity section 20 on the other longitudinal side Ls can be changed with respect to the cylindrical high-rigidity section 20 on the one longitudinal side Lf.

Since it extends toward the cylindrical high-rigidity part 20f) of the cylindrical high-rigidity part 20h, a separate low-rigidity part forming part 110h is joined to the joint piece 24 of the cylindrical high-rigidity part 20h to form a plate-like low-rigidity part. 10h. Therefore, the low-rigidity portion forming portion 110h and the joining piece 24 come into surface contact, and compared to a structure in which the low-rigidity portion forming portion 110 and the cylindrical high-rigidity portion 20 are joined by butting each other, the plate-like low-rigidity portion 10h has a more reliable connection.
