Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
FIG. 1 shows a schematic perspective view of a protector 1 according to the first embodiment, and specifically shows a schematic perspective view of the protector 1 with a clip 20 attached to a protector body 10. FIG. 2(a) shows a schematic perspective view of the anchor portion 30 side of the clip 20 of the first embodiment, and FIG. 2(b) shows a schematic perspective view of the clip body portion 40 side of the clip 20 of the first embodiment. .

FIG. 3 shows a schematic perspective view of the state before the clip 20 is attached to the attachment hole 12 in the protector main body 10. FIG. 4(a) shows a schematic perspective view of the clip 20 attached to the protector body 10 before the locking portion 44 is formed, and FIG. 4(b) shows a sectional view of the same state. FIG. 5(a) shows a schematic perspective view of the clip 20 attached to the protector main body 10 after the locking portion 44 is formed, and FIG. 5(b) shows a sectional view of the same state.

In FIG. 1, the clip 20 attached to one of the two attachment holes 12 provided in the protector body 10 is illustrated in a see-through state. Also, in FIG. 1, the wire harness WH inserted into the internal space S of the protector body 10 is illustrated in a see-through state.

The protector 1 is constructed by attaching a clip 20 to an attachment hole 12 in a protector main body 10 having a rectangular cylindrical shape.
The protector main body 10 is a rectangular cylindrical body having a substantially square shape when viewed from the side, and has an internal space S penetrating in the longitudinal direction L therein. This internal space S is a space through which the wire harness WH is inserted in the longitudinal direction L.

As shown in FIG. 1, the longitudinal direction of the protector body 10, which is an inverted rectangular tube, is defined as the longitudinal direction L, and the direction perpendicular to the longitudinal direction L is defined as the width direction W. The direction in which the clip 20 is inserted into the mounting hole 12 of the protector body 10 is defined as the insertion direction I.

The protector main body 10 is constructed by bending a resin sheet. In detail, the protector body 10, which is a rectangular cylindrical body with a substantially square shape when viewed from the side, is made by folding a continuous resin sheet at each side, overlapping one side and welding the same. It is composed of

In this embodiment, the upper surface member 11 and the opposing bottom surface are overlapped, but one side of the pair of side surfaces may be overlapped. Alternatively, a plurality of consecutive surfaces may be stacked.

The density of the thermoplastic resin foam sheet constituting the protector body 10 is not particularly limited, but for example, it is possible to prevent anisotropy in mechanical properties, that is, to make the mechanical properties isotropic, giving freedom in designing the protector body 10. In order to further improve the strength against the stress in the WH direction of the wire harness housed in the protector main body 10, the range is preferably 200 Kg/m ³ or more and 1000 Kg/m ³ or less, and has both light weight and mechanical strength. From the viewpoint of further improving the balance, the range 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 main body 10 is not particularly limited, but may have, for example, ease of bending and mechanical strength, especially mechanical strength against stress in the WH direction of the wire harness housed in the protector main body 10. In order to further improve the balance with strength, the thickness 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. Moreover, 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 main body 10 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 body 10 is not particularly limited, and the lower limit is 800 cells 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 above-mentioned cell number density may be, for example, 1010 cells/mm ³ or less, from the viewpoint of more reliably obtaining excellent mechanical strength.
Each surface of the protector main body 10, which is constructed by folding a resin sheet as described above, including the upper surface member 11, is configured in a plate shape.

As described above, a plurality of mounting holes 12 are provided at predetermined intervals in the longitudinal direction L in the upper surface member 11 of the protector main body 10 which is made of a resin sheet and has a rectangular cylindrical shape. Although two attachment holes 12 are provided in this embodiment, an appropriate number of clips 20 can be attached depending on various conditions such as the length of the protector body 10 and the weight of the wire harness WH inserted into the internal space S. The number of attachment holes 12 may be provided as many as necessary.

The attachment hole 12 is a substantially rectangular opening in plan view that penetrates the upper surface member 11 in the thickness direction, that is, in the insertion direction I. In other words, the mounting hole 12 has a substantially rectangular shape in plan view, and has a rotation preventing shape that is not a perfect circle.As will be described in detail later, this makes it possible to prevent the clip 20 from rotating.

As shown in FIG. 2, the clip 20 that is attached to the attachment hole 12 in the upper surface member 11 has an anchor part 30 that is inserted into an anchor hole (not shown) provided in a predetermined attachment location such as the engine room of a vehicle, and The clip main body part 40 is inserted into the hole 12.

The anchor part 30 has a generally dish-shaped dish part 31 that is pressed against the vehicle body panel when the anchor part 30 is attached to the anchor hole, and an insertion locking part 32 that extends from the center of the dish part 31 and is inserted into the anchor hole and locked. The tip of the insertion locking part 32 has a locking arm 33 that extends in an inverted V shape toward the dish part 31. When the anchor part 30 is configured in this way and attached to the anchor hole, the locking arm 33 flexes and passes through the anchor hole, and the anchor part 30 is attached so that the vehicle body panel is sandwiched between the dish part 31 and the locking arm 33.

The clip main body 40 is made of polypropylene, a thermoplastic resin, and as shown in Figure 2, is composed of an insert 41 formed to a predetermined length and a temporary fastening portion 42 that protrudes from the tip portion of the insert 41 in a direction intersecting the insertion direction I.
Among the directions perpendicular to the insertion direction I, the long side direction of the insert 41 having a generally rectangular shape in a plan view is defined as a long side direction X, and the short side direction of the insert 41 is defined as a short side direction Y (see FIG. 2).

The insert body 41 has a substantially rectangular rod shape when viewed from above, and is formed in a shape corresponding to the attachment hole 12 . Further, the length of the insert body 41 in the insertion direction I is longer than the plate thickness of the upper surface member 11, and the width in the long side direction X and the short side direction Y is longer than the long side and short side of the mounting hole 12. It is formed slightly smaller. Note that the tip of the insert body 41 in the insertion direction I is formed with a tapered portion 411 whose width in the long side direction X tapers toward the tip.

The temporary fixing portions 42 are provided on both sides of the long side portion of the insert body 41 in a plan view, and are formed to protrude toward the short side direction Y. The temporary fixing parts 42 are formed such that the distance from the top of one temporary fixing part 42 to the top of the other temporary fixing part 42 is slightly longer than the length of one side of the attachment hole 12.

In addition, each temporary fixing part 42 has a chevron-shaped cross-sectional shape along the insertion direction I, and the slope angle of the slope on the distal end side in the insertion direction I is gentler than the slope angle of the slope surface on the rear end side in the insertion direction I. is formed. Each temporary fixing part 42 is formed at a position where the distance between the rear end and the end of the insert body 41 in the insertion direction I is slightly smaller than the thickness of the upper surface member 11. In other words, the distance between the rear end of the temporary fixing part 42 and the dish part 31 of the anchor part 30 is narrower than the length of the attachment hole 12 along the insertion direction I.

In the clip main body 40, the insert 41 and the temporary fastening part 42 are entirely made of a molten material such as a thermoplastic resin material that melts at a predetermined temperature. That is, by heating at a temperature exceeding the melting point, the molten body can be melted and deformed, and by stopping the heating in the deformed state, the heated part can be maintained in the shape after deformation.
More specifically, by applying heat of 150 to 160° C., the entire insert body 41 and temporary fixing portion 42 can be melted and deformed.

As shown in FIG. 3, the clip 20 configured in this manner can be moved along the insertion direction I with respect to the attachment hole 12 of the upper surface member 11, so that the clip body 40 can be inserted into the attachment hole 12. Can be done. Note that the peripheral edge of the plate-shaped attachment hole 12 is pressed by the temporary attachment portion 42 and deforms when the clip main body portion 40 is passed through the attachment hole 12 .

When the temporary fastening portion 42 penetrates the mounting hole 12, as shown in Figures 4(a) and 4(b), the temporary fastening portion 42 protruding in the short side direction Y engages with the periphery of the mounting hole 12, and the clip 20 is temporarily fastened to the protector body 10.

Here, since the width of the insert body 41 in the long side direction In the temporarily fastened state in which the insert body 41 is locked to the inner surface of the attachment hole 12, a slight gap is formed between the insert body 41 and the inner surface of the attachment hole 12.

Further, the surface of the dish portion 31 of the anchor portion 30 on the protector main body 10 side is in contact with the peripheral edge of the attachment hole 12 on the opposite side from the temporary fixing portion 42. That is, the dish portion 31 functions as a regulating body that regulates the insertion position of the insert body 41 into the attachment hole 12. In addition, since the distance between the rear end of the temporary fixing part 42 and the dish part 31 of the anchor part 30 is narrower than the thickness of the top member 11, the temporary fixing part 42 and the dish part 31 are connected to the periphery of the mounting hole 12 in the top member 11. It is in a state where the parts are held in place.

Then, in the clip main body 40 temporarily fixed to the peripheral edge of the attachment hole 12, the heated portion 43 of the insert 41 that protrudes from the attachment hole 12 toward the distal end side in the insertion direction I is melted, so that the locking portion 44 (see FIGS. 5(a) and 5(b)), and the attachment of the clip 20 to the protector body 10 can be completed.

Specifically, the heated portion 43 is heated and melted by a heater or the like from the distal end side in the insertion direction I, and the heated portion 43 is compressed and deformed toward the protector main body 10. As a result, a part of the heated portion 43 enters the gap between the mounting hole 12 and the insert body 41 and is deformed so as to expand the periphery of the mounting hole 12 and extend in a plane direction along the periphery of the mounting hole 12. A plate-shaped locking portion 44 is formed.

The locking part 44 formed in this way is locked to the peripheral edge of the mounting hole 12 so as to cover the mounting hole 12, and is also in contact with the peripheral edge of the mounting hole 12 on the opposite side from the temporary fastening part 42. The peripheral edge of the attachment hole 12 is held between the contacting surface of the plate portion 31 on the protector main body 10 side.

Furthermore, by forming the locking portion 44 by melting the heated portion 43, a part of the melted heated portion 43 enters the gap between the mounting hole 12 and the insert body 41, and is inserted in the temporary state. The gap formed on the tip side in direction I can be filled (see FIG. 5(a)).

Furthermore, as the heated portion 43 melts, at least a portion of the peripheral edge and inner surface of the mounting hole 12 is also melted, so that the locking portion 44 formed from the heated portion 43 and the peripheral edge of the mounting hole 12 are melted. It can be welded to the inner surface.

Specifically, since the protector body 10 is made of a thermoplastic resin foam sheet, the peripheral edge and inner surface of the mounting hole 12 that come into contact with the heated portion 43 are melted together with the heated portion 43. Thereafter, by stopping the heating of the heated portion 43, the melted peripheral edge and inner surface portion of the attachment hole 12 and the locking portion 44 formed from the heated portion 43 can be welded together.

In this way, the protector 1 with the clip 20 attached to the top member 11 of the protector body 10 has the wire harness WH inserted into the internal space S of the protector body 10. Then, the protector 1 with the wire harness WH inserted into the internal space S can be attached to the specified installation location by inserting the anchor portion 30 of the clip 20 into an anchor hole (not shown) provided in a specified installation location such as the engine room of the vehicle. This allows the wire harness WH that passes through the internal space S of the protector 1 to be routed along a specified routing path, and the wire harness WH that passes through the internal space S can be protected.

In this way, the protector 1 includes the protector body 10 that is attached to a predetermined anchor hole, and the clip 20 that is attached to the attachment hole 12 in the protector body 10, projects toward the anchor hole, and attaches the protector body 10 to the anchor hole. It consists of The clip 20 is provided with an insert 41 that is inserted into the attachment hole 12, and the insert 41 is made of a molten material that melts at a predetermined temperature. Then, in the insert body 41 inserted into the mounting hole 12, the molten material is melted to form a locking part 44, and the locking part 44 locks in the mounting hole 12, and the clip 20 is inserted into the mounting hole 12. installed.

Thereby, the attachment stability of the clip 20 to the protector main body 10 can be improved.
In detail, since the locking part 44 is formed by melting the tip of the locking part 44, which is a molten body, the locking part 44 can be attached to the peripheral edge of the mounting hole 12 without being affected by tolerances. It can be locked without any gaps.

In addition, when the tip portion of the insert 41 inserted into the mounting hole 12 melts, a portion of the molten insert 41 (molten material) travels along the insert 41, and at least a portion of the gap between the insert 41 and the mounting hole 12 is filled with the molten material. In other words, at least a portion of the gap between the insert 41 and the mounting hole 12 is filled with the molten material.

In this way, the clip 20 is attached to the attachment hole 12 without any gap by the locking portion 44 made of a thermoplastic resin material, so that relative movement of the clip 20 with respect to the attachment hole 12 is suppressed. Therefore, rattling of the clip 20 can be suppressed. Thereby, the attachment stability of the clip 20 to the protector main body 10 can be improved.

Further, the locking portion 44 protrudes in a direction intersecting the penetrating direction of the mounting hole 12 and is locked to the peripheral edge of the mounting hole 12 . As a result, the clip 20 can be attached to the protector main body 10 without providing any special configuration to the attachment hole 12, simply by providing the locking portion 44 protruding in the cross direction. This allows the overall configuration to be simplified.

Further, since the mounting hole 12 has a substantially rectangular shape in plan view and has a non-rotation prevention shape that is not a perfect circle, it is possible to prevent the clip 20 attached to the protector main body 10 from rotating, and the clip 20 relative to the protector main body 10 can be prevented from rotating. The mounting stability can be further improved.

To be more specific, the shape of the mounting hole 12 is not a perfect circle, and has a rotation-preventing shape in which a distance from the center of gravity of the mounting hole 12 is different from other parts when viewed from above. As a result, the rotation of the melted insert 41 is regulated so that a portion of the insert 41 has substantially the same shape as the attachment hole 12 . In other words, the locking part 44, which is formed by melting a part of the insert 41, is configured so that the gap between the insert 41 and the mounting hole 12 is filled with the molten material. The insert body 41 has substantially the same shape as the mounting hole 12 . Thereby, the insert body 41 (locking portion 44) can be prevented from rotating with respect to the attachment hole 12, and the stability of the clip 20 with respect to the protector main body 10 can be improved.

Further, since the insert body 41 has a substantially rectangular shape in plan view and has a shape corresponding to the mounting hole 12 which has a substantially rectangular shape in plan view, the gap between the insert body 41 and the mounting hole 12 can be reduced. Thereby, the gap created between the insert body 41 and the attachment hole 12 can be reliably filled with the molten insert body 41, and rattling and rotation of the clip 20 with respect to the protector body 10 can be suppressed. Also, when the clip 20 is attached to the protector main body 10, rattling and rotation of the clip 20 is suppressed, and the workability of the attaching operation can be improved.

Further, the clip 20 is provided with a plate portion 31 that is disposed at the rear of the insert body 41 in the insertion direction I and that regulates the insertion position of the insert body 41 into the mounting hole 12. Since the attachment hole 12 is sandwiched, rattling of the clip 20 can be further suppressed.

Furthermore, since at least a portion of the melted portion on the protector body 10 that melts as the heated portion 43 melts is welded to the locking portion 44, the clip 20 can be attached to the protector body 10 more stably. Therefore, the attachment stability of the clip 20 to the protector body 10 can be further improved.

In addition, a temporary fixing portion 42 is provided at the tip of the insert body 41 and protrudes in a direction intersecting the penetrating direction of the mounting hole 12 (insertion direction I) and is locked to the peripheral edge of the mounting hole 12. When the insert body 41 is inserted into the attachment hole 12, the insert body 41 can be temporarily fixed to the attachment hole 12 by the temporary attachment part 42. This eliminates the need for the operator to support the clip 20 when melting the heated portion 43. Therefore, the workability of the mounting work can be improved.

Further, in a method of fixing the protector body 10 in which a clip 20 is attached to the protector body 10 to be attached to a predetermined anchor hole, and the protector body 10 is attached to the anchor hole via the clip 20, the insert body 41 is attached to the attachment hole 12. The clip 20 is attached by inserting the insert body 41, melting the insert body 41 to form a locking portion 44, and locking the locking portion 44 in the mounting hole 12. Thereby, the fixing structure of the protector main body 10 described above can be efficiently obtained.

Furthermore, a temporary fixing part 42 is provided at the distal end portion of the insert body 41 so as to protrude in a transverse direction intersecting the penetrating direction of the mounting hole 12 and to be locked to the peripheral edge of the mounting hole 12 . Then, in the fixing method, the insert body 41 is inserted into the mounting hole 12, the temporary fixing part 42 is locked to the peripheral edge of the mounting hole 12, and the insert body 41 is melted to form the locking part 44, The clip 20 is attached to the mounting hole 12 by locking the locking portion 44 to the mounting hole 12.

Thereby, when the insert body 41 is inserted into the attachment hole 12, the insert body 41 can be temporarily fixed to the attachment hole 12 by the temporary fixing portion 42. This eliminates the need for the operator to support the clip 20 when melting the heated portion 43. Therefore, the workability of the mounting work can be improved, and the above-described fixing structure for the mounted member can be efficiently obtained.

In addition, the protector body 10 is lightweight and made of a resin sheet with high deformability, so it is easy to handle, and the insert body 41 is provided on the upper surface member 11 of the protector body 10 made of a resin sheet. The clip 20 can be attached by easily inserting it into the attached attachment hole 12.

Furthermore, since the protector main body 10 is constructed by bending a plate-shaped resin sheet with high workability, the protector main body 10 having a desired three-dimensional shape can be easily constructed.

Next, a protector 1a according to a second embodiment will be described with reference to FIGS. 6 and 7.
Note that FIG. 6(a) shows a cross-sectional plan view of the clip 20a attached to the protector main body 10a before the locking portion 44a is formed, and FIG. 6(b) shows a cross-sectional front view of the same state. FIG. 7(a) shows a cross-sectional plan view after the locking portion 44a is formed in the clip 20a attached to the protector main body 10a, and FIG. 7(b) shows a cross-sectional front view of the same state.

Further, in the following description, the same components as those of the protector 1 described above are given the same reference numerals, and the explanation thereof will be omitted, and the different components will be explained in detail.
As shown in FIGS. 6 and 7, the protector 1a is composed of a protector main body 10a and a clip 20a. In the protector main body 10a, recesses 13 are formed on each surface of the inner surface of the attachment hole 12. Further, the insert body 41a in the clip 20a is formed to be shorter than the hole length of the attachment hole 12. The insert body 41a is configured such that, when inserted into the attachment hole 12, the tip end is located closer to the tip side in the insertion direction I than the recess 13 in the attachment hole 12.

When the insert 41a of the clip 20 thus configured is inserted into the mounting hole 12, the heated portion 43, which is the tip of the insert 41a in the insertion direction I, is melted to form the locking portion 44a so that the heated portion 43 fits into each recess 13. At this time, the heated portion 43 deforms so as to spread over the inner surface of the mounting hole 12, forming the locking portion 44a in a shape corresponding to the recess 13, and each locking portion 44a can be locked into each recess 13 (see Figures 7(a) and 7(b)).

In such a protector 1a, a recess 13 is formed on the inner surface of the attachment hole 12, and a locking portion 44a is formed in a shape corresponding to the recess 13 and is locked in the recess 13. Thereby, the locking portion 44a can be locked in the recess 13 formed on the inner surface of the mounting hole 12 without the distal end portion of the insert body 41a protruding from the mounting hole 12 toward the distal end side in the insertion direction I. Therefore, it is possible to prevent the insert body 41a from interfering with other members, and it is possible to improve the attachment stability of the clip 20 to the protector main body 10a.

Next, a protector 1b according to a third embodiment will be described with reference to FIGS. 8 and 9.
In addition, FIG. 8 shows a plan view of the protector main body 10b, FIG. 9(a) shows a plan view after forming the locking part 44 in the clip 20b attached to the protector main body 10b, and FIG. 9(b) shows a cross-sectional view of the same state.

In the following description, the same components as those of the protector 1 described above will be denoted by the same reference numerals and the description thereof will be omitted, and only the different components will be described in detail.
The protector 1b is composed of a protector body 10b and a clip 20b.

In the protector main body 10b, as shown in FIG. 8, a plurality of recesses 13b are formed at the peripheral edge of the attachment hole 12 on the front surface of the upper surface member 11 in the insertion direction I.
By melting the heated portion 43 with the insert 41 of the clip 20b configured as described above inserted into the mounting hole 12, the tip of the upper surface member 11 in the insertion direction I is melted, as shown in FIG. 9(a). A deformed plate-shaped locking portion 44 is formed so as to widen the peripheral edge of the attachment hole 12 on the side surface.

At this time, the locking portion 44b that has expanded into a planar plate shape is formed with a convex locking portion 45 so as to fit into each recess 13b, and each convex locking portion 45 locks in each recess 13b. . As a result, the locking portion 44 locks with the protector main body 10b, and the convex locking portions 45 lock with each recess 13b.

In the protector 1b configured in this way, a recess 13b is formed at the peripheral edge of the mounting hole 12, and the molten material is melted to form a convex locking portion 45 as a second locking portion having a shape corresponding to the recess 13b. Then, the convex locking portion 45 locks in the recess 13b. As a result, the clip 20b can be attached to the protector body 10b by the locking part 44 and the convex locking part 45, and rattling of the clip 20b can be further suppressed, and the protector body 10b can be stably attached to the anchor hole. can.

Next, a protector 1c according to a fourth embodiment will be described with reference to FIG. 10.
Note that FIG. 10 shows a cross-sectional view of the clip 20c attached to the protector main body 10 after the locking portion 44 is formed.

In the following description as well, the same components as those of the protector 1 described above are given the same reference numerals, and the explanation thereof will be omitted, and the different components will be explained in detail.

As shown in FIG. 10, the protector 1c is composed of a protector body 10, a clip 20c, and a length adjustment sleeve 50.

In the clip 20c, the insert body 41c is formed longer than the insert body 41, and has an uninserted portion 412c that is not inserted into the attachment hole 12 on the rear end side in the insertion direction I.

The length adjustment sleeve 50 is a substantially cylindrical member, and is attached to the uninserted portion 412c of the insert body 41c in a state where it is inserted into the uninserted portion 412c. This length adjustment sleeve 50 is formed with a length corresponding to the length of the uninserted portion 412c, and the front end side surface in the insertion direction I is aligned with the peripheral edge of the mounting hole 12 on the rear end side of the insertion direction I. The rear end side surface in the insertion direction I is in contact with the dish portion 31 . As a result, even when a force along the insertion direction I is applied to the insert body 41c, the length adjustment sleeve 50 has one surface in contact with the peripheral edge of the mounting hole 12 and the other surface in contact with the dish portion 31. Therefore, relative movement of the insert body 41c in the insertion direction I with respect to the attachment hole 12 is restricted.

In the protector 1c, the length adjustment sleeve 50 is inserted into the insert 41c, and the clip 20c is inserted into the attachment hole 12 of the protector body 10, and the heated portion 43 is melted in the same manner as described above. A locking portion 44 can be formed. Thereby, the clip 20c can be attached to the protector main body 10.

In this way, the insert 41c of the protector 1c has a non-inserted portion 412c at the rear end side in the insertion direction I that is not inserted into the mounting hole 12, and a length adjustment sleeve 50 is attached to the non-inserted portion 412c, which abuts the peripheral portion of the mounting hole 12 at the rear end side in the insertion direction I. This improves the attachment stability of the clip 20 to the protector body 10a, regardless of the thickness of the protector body 10, etc.

In more detail, depending on the thickness of the protector body 10, not all of the insert 41c may be inserted into the mounting hole 12, but a portion may be left uninserted in the mounting hole 12. Since a length adjustment sleeve 50 is attached to such an uninserted portion 412c, the relative movement of the insert in the insertion direction can be restricted. Therefore, regardless of the thickness of the protector body 10, the attachment stability of the clip 20 to the protector body 10a can be improved.

Next, a protector 1d according to a fifth embodiment will be described with reference to FIG. 11.
Note that FIG. 11 shows a cross-sectional view after the locking portion 44 is formed in the clip 20d attached to the protector main body 10d.

In the following description as well, the same components as those of the protector 1 described above are given the same reference numerals, and the explanation thereof will be omitted, and the different components will be explained in detail.

As shown in Figure 11, the protector 1d is composed of a protector body 10d and a clip 20d.

The protector main body 10d is provided with a mounting hole 12d that penetrates the upper surface member 11 along a direction inclined with respect to the thickness direction of the upper surface member 11.
The clip 20c is provided with an insert 41d that is inclined with respect to the dish portion 31 at the same angle of inclination as the angle of inclination of the attachment hole 12d. Therefore, when the insert body 41d is inserted into the attachment hole 12d, the dish portion 31 comes into contact with the peripheral edge of the attachment hole 12d in a state parallel to the upper surface member 11. Therefore, as described above, by forming the locking portion 44 by melting the heated portion 43, even if the mounting hole 12d is inclined, the locking portion 44 and the plate portion 31 can be mounted. The hole 12d can be sandwiched.

In such a protector 1d, the mounting hole 12d is configured as an inclined through hole whose penetration direction is inclined with respect to the thickness direction of the upper surface member 11, and the insert body 41d is inserted into the mounting hole 12d which is the inclined through hole. has been done. As a result, rotation around the thickness direction of the insert body 41d inserted into the mounting hole 12d, which is an inclined through hole, is restricted.

Next, a protector 1e according to a sixth embodiment will be described with reference to FIGS. 12 and 13.
Note that FIG. 12 shows a cross-sectional view of the clip 20e attached to the protector body 10e before forming the locking part 44e, and FIG. 13 shows a cross-sectional view of the clip 20e attached to the protector body 10e after forming the locking part 44e. A cross-sectional view is shown.

In the following description as well, the same components as those of the protector 1 described above are given the same reference numerals, and the explanation thereof will be omitted, and the different components will be explained in detail.
As shown in FIG. 12, the protector 1e is composed of a protector main body 10e and a clip 20e.

The protector body 10e is provided with two attachment holes 12e that penetrate the protector body 10 along the insertion direction I.
The clip 20e is provided with two insertion pieces 413e corresponding to the insertion body 41e. This insertion piece 413e is provided at a position corresponding to each attachment hole 12e, and is formed longer than the hole length of each attachment hole 12e.

In the protector 1e in which the clip 20e configured as described above is attached to the protector main body 10e, as shown in FIG. A locking portion 44e is formed by deforming the peripheral edge of the locking portion 44e so as to expand. The locking portion 44e is integrally formed by the melted insertion pieces 413e colliding with each other between the two attachment holes 12e and being partially welded to each other.

Such a protector 1e is provided with a plurality of attachment holes 12e, and the insert body 41e is provided with a plurality of insertion pieces 413e corresponding to the attachment holes 12e, each of which is inserted into each of the plurality of attachment holes 12e. Thereby, each insertion piece 413e can function as a rotation stopper when the insert body 41e rotates around the other insertion piece 413e. This can prevent the insert 41e from rotating with respect to the attachment hole 12e.

In addition, since each of the locking portions 44e formed from each insertion piece 413e is partially welded to each other, the locking portions 44e are more easily locked into the mounting hole 12e than when they are separate. is made stronger.

In the correspondence between the configuration of this invention and the above-described embodiments, the mounting location of this invention corresponds to the anchor hole,
Similarly below,

Although the temporary fixing portion corresponds to the temporary fixing portion 42, the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

In the above description, the entire insert 41 is made of a molten material that melts at a predetermined temperature, but this is not necessarily limited to this, and it is sufficient that at least the tip portion of the insert 41 in the insertion direction is made of a molten material, and the range made of the molten material may be changed as appropriate. In addition, the entire portion of the insert 41 made of the molten material may be used to form the locking portion, or only a portion of it may be melted to form the locking portion.

In addition, the hole shape of the mounting hole 12 is rectangular, and the insert 41 is also rectangular, but this is not necessarily limited to this. For example, the hole shape of the mounting hole 12 may be a perfect circle, and even if the hole shape is designed to prevent rotation, it is not limited to a rectangle, and may be changed appropriately to various shapes such as an H shape that can prevent the insert from rotating. Furthermore, the shape of the insert 41 may be different from the hole shape of the mounting hole 12, and even if it corresponds to the hole shape of the mounting hole 12, it may be a shape that fits into part of the mounting hole 12 and prevents rotation, rather than being a similar shape to the mounting hole 12.

In the above description, a small gap is formed between the insert 41 and the inner surface of the mounting hole 12, and a part of the molten heated portion 43 is inserted into the gap. However, this is not necessarily limited to this, and the insert 41 may be inserted into the mounting hole 12 without any gap.

Furthermore, in the above description, as the heated portion 43 melts, at least part of the peripheral edge and inner surface of the attachment hole 12 is melted and welded to the locking portion 44 formed from the heated portion 43. However, it is not necessarily limited to this. For example, the protector body 10 may be made of a material that is difficult to melt, so that at least a portion of the peripheral edge or inner surface of the attachment hole 12 does not melt as the heated portion 43 melts.

Furthermore, in the above description, the dish portion 31 functions as a restricting body that restricts the insertion position of the insert 41 into the mounting hole 12, and the peripheral portion of the mounting hole 12 is clamped between the locking portion 44 and the dish portion 31, but this is not necessarily limited to this. The peripheral portion of the mounting hole 12 does not necessarily have to be clamped between the dish portion 31 and the locking portion 44, and a structure equivalent to a restricting body does not necessarily have to be provided.

In the above description, the clip body 40 is provided with a temporary fastening portion 42, but this is not necessarily limited to this. The configuration of the temporary fastening portion 42 may be modified as appropriate as long as it protrudes in a direction intersecting the penetrating direction of the mounting hole 12 and can be engaged with the peripheral portion of the mounting hole 12, and the temporary fastening portion 42 does not necessarily have to be provided.

Furthermore, the locking manner of the locking portion is not necessarily limited to that shown in the above explanation, and the locking manner of the locking portion may be any configuration as long as it locks with the mounting hole. Good too.
For example, in the protector 1, a plate-shaped locking portion 44 extending in a plane direction along the peripheral edge of the mounting hole 12 is formed as a locking portion that locks on the peripheral edge of the mounting hole 12. It may be changed as appropriate as long as it protrudes in the intersecting direction. For example, a rod-shaped locking portion extending in the long side direction X or the short side direction Y may be formed in the attachment hole 12.

For example, in the protector 1a, the locking portion 44a that locks into the recess 13 formed on the inner surface of the mounting hole 12 is formed, but the invention is not limited to this. A concave portion into which the convex portion fits may be formed as a portion.

For example, in the protector 1b, the recess 13b is provided at the peripheral edge of the attachment hole 12, and the convex locking portion 45 that locks in the recess 13b is formed as the second locking portion, but the invention is not necessarily limited to this. It is also possible to form a convex part instead of a concave part on the peripheral edge of the mounting hole 12, and to form a concave part into which the convex part fits as the second locking part. A concave portion or a convex portion may be formed on the inner surface of the attachment hole 12, and a second locking portion that is engaged with the concave portion or the convex portion may be formed. Alternatively, a concave portion or a convex portion may be formed on both the peripheral edge and the inner surface of the mounting hole 12, and a locking portion that locks with each may be formed.

Alternatively, the peripheral edge of the attachment hole 12 may be recessed relative to other parts, and the heated portion 43 melted within the recessed area may be expanded to form the locking portion 44. Thereby, the locking part 44 does not protrude with respect to the surroundings, and interference of the insert body 41 with other members can be avoided. In addition, at this time, if the peripheral edge of the mounting hole 12 is recessed in accordance with the shape of the intended locking part and a locking part with the same shape as the recessed area is formed, wobbling of the clip 20 can be further reduced. It can be suppressed.

Further, in the above description, the height adjustment sleeve 50 is a substantially cylindrical member, and the surface on the distal end side in the insertion direction I is in contact with the peripheral edge of the mounting hole 12 on the rear end side in the insertion direction I. The structure is such that the surface on the rear end side is in contact with the dish portion 31. However, the configuration of the height adjustment sleeve 50 is not necessarily limited to this, and may be modified as appropriate as long as it is attached to the uninserted portion 412c and comes into contact with the peripheral edge of the attachment hole 12 on the rear end side of the insertion direction I. You may.

Furthermore, regarding the method of attachment to the uninserted part 412c, it is possible not only to insert the insert body 41c in advance, but also to provide a slit and pass the insert body 41c inside through the slit, or to construct the uninserted part 412c with a divided member. Alternatively, the insert body 41c may be sandwiched between the insert body 41c.

Furthermore, in the above description, the entire mounting hole 12d is an inclined through hole that is inclined with respect to the thickness direction, but this is not necessarily the case. It is also possible to have a zigzag shape composed of an inclined portion that is inclined with respect to the thickness direction, and the insert body 41c may be inserted up to at least the inclined portion.

Further, although the insert body 41c is configured to be inclined with respect to the dish portion 31, an insert body that is not inclined with respect to the dish portion 31 may be made to be inclined with respect to the thickness direction as it is inserted into the attachment hole 12d. good.
Furthermore, in the above description, the protector 1e has a configuration in which two attachment holes 12e are provided, but the present invention is not necessarily limited to this, and three or more attachment holes 12e may be provided. Further, the number of insertion pieces 413e does not necessarily have to be the same as the number of attachment holes 12e, and the locking portions 44e formed from each insertion piece 413e do not need to be welded to each other. In addition, each insertion piece 413 can be bent toward each other, and by bending each insertion piece 413 toward each other and welding the abutting ends to each other, the insertion pieces 413 can be locked to the peripheral edge of the mounting hole 12e. Good too.

In the above description, the clip 20 is attached to the attachment hole 12 provided in the upper surface member 11 of the protector body 10, but the clip 20 may be attached to the side or bottom surface of the protector body 10. Furthermore, the clips 20 may be attached to different surfaces of the protector body 10.

Although the protector main body 10 has a rectangular cylindrical shape in the rectangular shape, it may be a polygonal cylindrical body such as a rectangular cylindrical shape or a triangular cylindrical shape with a flat rectangular cross section, or it may be cylindrical. Furthermore, it may have a rectangular U-shaped cross section or an L-shaped cross section.
Furthermore, although the clip 20 is provided with the convex locking portion 45 and the positioning recess 121 is formed in the mounting hole 12, the clip 20 may be provided with a convex locking portion and the positioning recess formed in the attachment hole 12.

In the above description, the clip body 40 is made of polypropylene, but it may be made of other thermoplastic resins. For example, it may be polyamide or polycarbonate. Furthermore, these thermoplastic resins may be changed as appropriate depending on the environment in which the clip 20 is placed.
