Description

[Technical Field]

[0001] The present invention relates to a protector and a wire harness. [Background technology]

[0002] As an example of a technology relating to a conventional wire harness protector, Patent Document 1 discloses a protector that includes a case provided with a storage space for storing a folded portion of a wiring material to be routed in a vehicle, and a cover attached to the case so as to cover the storage space from one side in the stacking direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-143606 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the wire harness described in the above-mentioned Patent Document 1, for example, grease is applied inside the case to enable the wiring material to slide smoothly, but because there is a gap between the inner corners between the bottom wall and the peripheral wall of the case and the wiring material, the grease is not stretched by the wiring material, and there is a risk of grease accumulation occurring.

[0005] The present invention has been made in view of the above circumstances, and has an object to provide a protector and a wire harness that can easily spread grease and can prevent the occurrence of grease accumulation. [Means for solving the problem]

[0006] In order to achieve the above object, the protector according to the present invention includes a case having a bottom wall extending along an extension direction and a peripheral wall protruding from a peripheral edge of the bottom wall to one side in a stacking direction intersecting the extension direction, the case having a storage space provided inside the peripheral wall for storing a folded portion of a wiring material to be routed in a vehicle, and a cover attached to the case so as to cover the storage space from one side in the stacking direction, the case and the cover having a connector that connects the storage space to the outside and allows the wiring material to be introduced into the storage space or drawn out of the storage space. A pair of openings is provided, and the peripheral wall includes a first peripheral wall located on one side of the width direction intersecting the extension direction and the stacking direction, connected to one end of the folded portion of the wiring material and facing a first straight portion extending along the extension direction, and a second peripheral wall located on the other side of the width direction, connected to the other end of the folded portion of the wiring material and facing a second straight portion extending along the extension direction, and the inner corners between the bottom wall and the first peripheral wall and the inner corners between the bottom wall and the second peripheral wall are each formed in a curved shape along the outer peripheral surface of the wiring material. [Effects of the Invention]

[0007] In the protector and wire harness according to the present invention, the inner corners between the bottom wall and the first peripheral wall of the case and the inner corners between the bottom wall and the second peripheral wall are each formed into a curved shape that follows the outer circumferential surface of the wiring material. With this configuration, the protector and wire harness can, for example, bring the inner corners of the case and the wiring material into close contact via grease, thereby reducing the gap between each of the inner corners and the wiring material. As a result, the protector and wire harness have the effect of making it easier to spread the grease and suppressing the occurrence of grease accumulation. [Brief explanation of the drawings]

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially identical. Note that in this specification, ordinal numbers are used only to distinguish between parts, members, portions, positions, directions, etc., and do not indicate order or priority.

[0010] [Embodiment] FIG. 1 is a perspective view of a wire harness WH to which a protector 1 according to an embodiment is applied. The protector 1 of the present embodiment shown in FIG. 1 is incorporated into the wire harness WH to be installed in a vehicle. Here, the wire harness WH is, for example, a composite component made up of multiple wiring materials W used for power supply and signal communication to connect various devices installed in the vehicle, and the multiple wiring materials W are connected to the various devices using connectors or the like. The wire harness WH of the present embodiment includes a conductive wiring material W and a protector 1 that protects the wiring material W. The protector 1 accommodates and protects a portion of the wiring material W, which is installed in, for example, a sliding seat or sliding door (not shown) installed in the vehicle, as an excess length. The wire harness WH may further include various other components, such as a corrugated tube, a grommet, an electrical connection box, a fixture, and a connector.

[0011] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "extension direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "stacking direction Z." Here, the extension direction X, width direction Y, and stacking direction Z are approximately perpendicular to one another. The extension direction X typically corresponds to the longitudinal direction of the protector 1, the insertion direction of the wiring material W into the protector 1, the longitudinal direction of the vehicle, etc. The width direction Y typically corresponds to the width direction of the case 10 and the cover 20 (see FIG. 3 ) in the protector 1, the vertical direction of the vehicle, etc. The stacking direction Z typically corresponds to the stacking direction of the case 10 and the cover 20 in the protector 1, the thickness direction of the protector 1, the width direction of the vehicle, etc. Furthermore, unless otherwise specified, the directions used in the following description will be described as directions when the protector 1 is assembled to the vehicle.

[0012] The wiring material W supplies power to electrical equipment installed in a sliding seat in a vehicle, for example. The wiring material W includes, for example, an electric wire bundle E1 in which a plurality of electric wires E (see FIG. 3) are bundled together, and a corrugated tube C as a tubular exterior material that covers the electric wire bundle E1. The wiring material W has relatively high flexibility and good bendability in an installed state in which the corrugated tube C is attached to the electric wire bundle E1. When the wiring material W of this embodiment is bent by applying an external force from a natural state (approximately straight state) in which no external force is applied, in an installed state in which the corrugated tube C is attached to the electric wire bundle E1, the bent portion elastically deforms, and an elastic reaction force is generated in the bent portion, causing it to return to its original state.

[0013] With a portion of the wiring material W housed in a housing space 4 (see FIG. 2) provided inside the protector 1, a portion of the wiring material W is introduced into the inside of the protector 1 as the sliding seat moves in one of the sliding directions, and is drawn out to the outside of the protector 1 as the sliding seat moves in the other of the sliding directions. One end of the wiring material W is electrically connected to an electrical component provided in the sliding seat, and the other end is electrically connected to a battery or the like mounted on the vehicle.

[0014] The protector 1 extends along the extension direction X and has a pair of openings 2 and 3 at one end in the extension direction X. The wiring material W is inserted through each of the openings 2 and 3 when the protector 1 is in a state in which a portion of the wiring material W is housed inside the protector 1. When the slide sheet slides in one direction, the wiring material W is introduced through one of the openings 2, and when the slide sheet slides in the other direction, the wiring material W is drawn out from the opening 2. When the wiring material W is in a state in which a portion of the wiring material W is housed inside the protector 1, one end of the wiring material W can be moved in and out of the protector 1 via the opening 2. On the other hand, when the wiring material W is in a state in which a portion of the wiring material W is housed inside the protector 1, the other end of the wiring material W is restricted from being moved in and out of the protector 1 via the opening 3. The protector 1 is installed, for example, in a vertical position with the width direction Y of the case 10 and cover 20 (described later) aligned along the vertical direction (the vehicle up-down direction), and a pair of mounting portions 14, 16 provided at both ends in the extension direction X are fastened to the vehicle body by fastening members such as bolts.

[0015] FIG. 2 is a perspective view of the case 10 of the protector 1, and FIG. 3 is a cross-sectional view of the wire harness WH. As shown in FIGS. 2 and 3, the protector 1 includes, for example, a case 10 and a cover 20. The case 10 and the cover 20 are formed, for example, from an insulating synthetic resin or the like. The cover 20 is assembled to the case 10 in a stacked state on one side of the case 10 in the stacking direction Z. The case 10 and the cover 20 are formed separately from each other and are integrated with each other, for example, by a claw engagement (snap fit) using a locking mechanism 30. The protector 1 is formed into a substantially rectangular parallelepiped shape as a whole by assembling the case 10 and the cover 20 to each other. The case 10 is also referred to as a base, etc.

[0016] The case 10 has, for example, a bottom wall 11 and a peripheral wall 12 provided on the peripheral edge of the bottom wall 11. The bottom wall 11 and the peripheral wall 12 are structures for partitioning the above-mentioned storage space 4 as the internal space of the protector 1. The storage space 4 is a space in which the wiring material W is stored. The bottom wall 11 is formed, for example, in a flat plate shape and extends along the extension direction X. A plurality of beads 18 (see FIG. 1 ) protruding along the stacking direction Z are provided on the outer surface of the bottom wall 11. The plurality of beads 18 are intended to reinforce the case 10 and are formed, for example, in a lattice shape extending along the extension direction X and the width direction Y.

[0017] The peripheral wall 12 protrudes from the peripheral edge of the bottom wall 11 to one side in the stacking direction Z. The peripheral wall 12 includes, for example, a first peripheral wall 12a located on one side in the width direction Y, a second peripheral wall 12b located on the other side in the width direction Y, and a third peripheral wall 12c located on the other end side in the extension direction X (the side opposite the openings 2 and 3). The first peripheral wall 12a and the second peripheral wall 12b extend linearly along the extension direction X. The third peripheral wall 12c is connected to the other ends of the first peripheral wall 12a and the second peripheral wall 12b in the extension direction X and is curved in an arc shape (semicircular shape) convex toward the other side in the extension direction X. The peripheral wall 12 is also referred to as a case-side peripheral wall, and the bottom wall 11 is also referred to as a case-side bottom wall.

[0018] Furthermore, one end of the case 10 in the extension direction X is provided with a wiring routing portion 15 through which the wiring material W is routed. The wiring routing portion 15 is connected to one end of the first peripheral wall 12a in the extension direction X and is curved in an arc shape (semicircular shape) while being convex toward one side in the extension direction X. The wiring routing portion 15 has a substantially U-shaped cross section that opens toward one side in the stacking direction Z (the cover 20 side), and is overlapped in the stacking direction Z with a wiring routing portion (not shown) on the cover 20 side. The internal spaces of the pair of wiring routing portions 15 function as insertion spaces through which the wiring material W is inserted, and one end of the insertion space forms the opening 2 described above, and the other end communicates with the storage space 4 described above.

[0019] A pair of mounting portions 14, 16 are provided at both ends of the case 10 in the extension direction X. The mounting portion 14 is provided in a state of protruding from the third peripheral wall 12c toward the other side in the extension direction X (the side opposite the openings 2, 3) and is overlapped in the stacking direction Z with a mounting portion (not shown) on the cover 20 side. The pair of mounting portions 14 are provided with mounting holes 14a through which fastening members such as bolts for fastening the protector 1 to the vehicle body pass in the stacking direction Z. The mounting portion 16 is provided at one end of the bottom wall 11 in the extension direction X and is overlapped in the stacking direction Z with a mounting portion (not shown) on the cover 20 side. The pair of mounting portions 16 are provided with mounting holes 16a through which fastening members such as bolts for fastening the protector 1 to the vehicle body pass in the stacking direction Z.

[0020] Additionally, a middle wall portion 15a of the wiring routing portion 15 described above is provided around the mounting portion 16. The middle wall portion 15a protrudes from the bottom wall 11 toward one side in the stacking direction Z (toward the cover 20) and is curved in an arc shape so as to connect the opening 2 and the opening 3 described above. The opening 2 is provided at one end of the middle wall portion 15a opposite to the accommodation space 4, and the opening 3 is provided at the other end of the middle wall portion 15a facing the accommodation space 4. Additionally, a protrusion 17 protruding from the bottom wall 11 toward one side in the stacking direction Z is provided at the other end of the middle wall portion 15a. The protrusion 17 is, for example, a portion that engages or fits into an annular recess formed on the outer peripheral surface of the corrugated tube C described above.

[0021] In this embodiment, the case 10 is provided with a plurality of protrusions 17 spaced apart from one another in the extension direction X. In this configuration, the other end of the wiring material W to which the corrugated tube C is attached is fixed to the case 10 by engagement between the plurality of protrusions 17 and an annular recess formed on the outer circumferential surface of the corrugated tube C. As a result, while the wiring material W is partially housed inside the protector 1, the other end of the wiring material W is restricted from moving the corrugated tube C into and out of the protector 1 through the opening 3. Note that, with respect to the other end of the wiring material W, a plurality of electric wires E inside the corrugated tube C can be pulled out to the outside of the protector 1 through the opening 3.

[0022] The cover 20 (see FIG. 3) is assembled to the case 10 and covers (closes) the storage space 4 of the case 10. The cover 20 has, for example, a cover-side bottom wall 21 and a cover-side peripheral wall 22 provided on the peripheral edge of the cover-side bottom wall 21. The cover-side bottom wall 21 and the cover-side peripheral wall 22 are structures for partitioning the storage space 4 as the internal space of the protector 1. The cover-side bottom wall 21 is formed, for example, in a flat plate shape and extends along the extension direction X so as to face the bottom wall 11 of the case 10. Similar to the case 10, a plurality of lattice-shaped beads protruding along the stacking direction Z may be provided on the outer surface of the cover-side bottom wall 21.

[0023] The cover-side peripheral wall 22 protrudes from the peripheral edge of the cover-side bottom wall 21 toward the other side in the stacking direction Z (toward the case 10). The cover-side peripheral wall 22 includes, for example, a cover-side first peripheral wall 22a located on one side in the width direction Y, a cover-side second peripheral wall 22b located on the other side in the width direction Y, and a cover-side third peripheral wall (not shown) connected to the cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b. The cover-side first peripheral wall 22a and the cover-side second peripheral wall 22b extend linearly along the extension direction X. The cover-side first peripheral wall 22a is overlapped on the outside of the case 10-side first peripheral wall 12a, and the cover-side second peripheral wall 22b is overlapped on the outside of the case 10-side second peripheral wall 12b. The cover-side third peripheral wall is overlapped on the outside of the case 10-side third peripheral wall 12c. The cover-side first peripheral wall 22a faces, for example, the floor surface of the vehicle.

[0024] The locking mechanism 30 has, for example, a claw portion provided on the case 10 side and a locking hole provided on the cover 20 side. The claw portion has a locking surface facing the other side in the stacking direction Z, and the locking hole has a locked surface facing the locking surface in the stacking direction Z. In the locking mechanism 30, the locking hole is locked (engaged) with the claw portion from the outside in the width direction Y. Then, by engaging the locking surface of the claw portion with the locked surface of the locking hole, movement (detachment) of the cover 20 to one side in the stacking direction Z relative to the case 10 is restricted.

[0025] The storage space 4 is formed within the protector 1 and communicates with the outside via a pair of openings 2 and 3 (see FIG. 2). When viewed from the stacking direction Z, the wiring material W arranged in the storage space 4 has a first straight portion W1 and a second straight portion W2, which are linearly arranged on both sides in the width direction Y, and a folded portion W3, which connects the first straight portion W1 and the second straight portion W2 and is folded back, arranged at the center in the width direction Y. The folded portion W3 is a portion of the wiring material W accommodated in the storage space 4 that is folded back in a U-shape from one side to the other in the extension direction X. The first straight portion W1 is a portion of the wiring material W accommodated in the storage space 4 that is connected to one end of the folded portion W3 and extends along the extension direction X so as to face the first peripheral wall 12a. The second straight portion W2 is a portion of the wiring material W accommodated in the accommodation space portion 4 that is connected to the other end of the folded portion W3 and extends along the extension direction X so as to face the second peripheral wall 12b.

[0026] The folded portion W3 moves along the extension direction X, for example, as the sliding sheet slides. Specifically, when the folded portion W3 is inserted into or removed from the opening 2 as the sliding sheet slides, it can move along the extension direction X between a first position P1 adjacent to the middle wall portion 15a of the wiring routing portion 15 and a second position P2 adjacent to the third peripheral wall 12c of the peripheral wall 12. As the sliding sheet slides, the wiring material W slides between the first position P1 and the second position P2 within the storage space 4. For this reason, grease G is applied to the outer peripheral surface C1 (see FIG. 3) of the wiring material W that slides within the storage space 4 to ensure smooth sliding.

[0027] Here, in this embodiment, the inner corners 13 between the bottom wall 11 and the first peripheral wall 12a and the inner corners 13 between the bottom wall 11 and the second peripheral wall 12b are each formed in a curved shape along the outer peripheral surface C1 of the wiring material W. That is, in this embodiment, when grease G is not applied (interposed) between the wiring material W and the inner corners 13, each inner corner 13 is formed in a shape that closely contacts the outer peripheral surface C1 of the wiring material W without any gaps. In other words, the inner corners 13 are provided with a convex portion that protrudes in a curved shape from a substantially right-angled base toward the wiring material W. The inner corners 13 are formed in a continuously curved shape so as to extend between one end and the other end of the first peripheral wall 12a and the second peripheral wall 12b in the extension direction X. Furthermore, in this embodiment, the inner corners 13 are formed in a curved shape along the outer peripheral surface C1 of the corrugated tube C of the wiring material W.

[0028] In addition, in this embodiment, the inner corner 13 between the bottom wall 11 and the third peripheral wall 12c is also formed in a curved shape along the outer peripheral surface C1 of the wiring material W. That is, in this embodiment, the inner corner 13 is formed in a curved shape continuously along the peripheral edge of the case 10, in other words, along the first peripheral wall 12a, the second peripheral wall 12b, the third peripheral wall 12c, and the wiring routing portion 15 (see FIG. 2). The inner corner 13 between the bottom wall 11 and each of the first peripheral wall 12a, the second peripheral wall 12b, the third peripheral wall 12c, and the wiring routing portion 15 is the portion where the wiring material W slides along the extension direction X as the slide sheet slides.

[0029] Therefore, according to this embodiment, the curved inner corner 13 enlarges the corner R of the case 10, increasing the contact area with the wiring material W, and thus reducing the gap between the inner corner 13 and the wiring material W. This prevents the grease G from being stretched by the wiring material W, thereby preventing grease accumulation at the inner corner 13. Furthermore, since the gap between the inner corner 13 and the wiring material W can be reduced, for example, there is an advantage in that the amount of grease G to be applied can be reduced. Even if the amount of grease G applied is reduced, the grease G is firmly stretched by the wiring material W, allowing the wiring material W to slide smoothly in the same manner (equivalently) as in the prior art. Furthermore, since grease accumulation is also eliminated, for example, even when the case 10 and the cover 20 are installed in a vertical position with the width direction Y of the case 10 and the cover 20 aligned vertically (the vehicle up-and-down direction), leakage of grease G from between the case 10 and the cover 20 can be prevented.

[0030] As described above, the protector 1 and the wire harness WH of this embodiment include a case 10 having a bottom wall 11 and a peripheral wall 12 protruding from the peripheral edge of the bottom wall 11 to one side in the stacking direction Z, and provided with a storage space 4 on the inside of the peripheral wall 12 for storing a folded portion W3 of a wiring material W to be routed in a vehicle, and a cover 20 attached to the case 10 so as to cover the storage space 4 from one side in the stacking direction Z. The case 10 and the cover 20 are provided with a pair of sleeves that communicate the storage space 4 with the outside and through which the wiring material W is introduced into the storage space 4 or drawn out of the storage space 4. The case 10 has openings 2 and 3, and the peripheral wall 12 includes a first peripheral wall 12a located on one side in the width direction Y and facing a first straight portion W1 connected to one end of the folded portion W3 of the wiring material W and extending along the extension direction X, and a second peripheral wall 12b located on the other side in the width direction Y and facing a second straight portion W2 connected to the other end of the folded portion W3 of the wiring material W and extending along the extension direction X. The inner corners 13 between the bottom wall 11 and the first peripheral wall 12a and the inner corners 13 between the bottom wall 11 and the second peripheral wall 12b are each formed in a curved shape along the outer circumferential surface C1 of the wiring material W. With this configuration, the protector 1 and the wire harness WH, for example, have the inner corners 13 of the case 10 in close contact with the wiring material W via grease G, thereby reducing the gap between each of the inner corners 13 and the wiring material W. As a result, the protector 1 and the wire harness WH can easily spread the grease G and can also suppress the occurrence of grease accumulation.

[0031] Furthermore, in the protector 1 and the wire harness WH of this embodiment, the peripheral wall 12 includes a third peripheral wall 12c that is connected to the first peripheral wall 12a and the second peripheral wall 12b and faces the folded-back portion W3, and the inner corner 13 between the bottom wall 11 and the third peripheral wall 12c is also formed in a curved shape that follows the outer peripheral surface C1 of the wiring material W. With this configuration, the protector 1 and the wire harness WH, for example, have the inner corner 13 between the bottom wall 11 and the third peripheral wall 12c and the wiring material W tightly contact each other via the grease G, which in turn makes it easier to spread the grease G and further suppresses the occurrence of grease accumulation.

[0032] Furthermore, in the protector 1 and the wire harness WH of this embodiment, the wiring material W includes a plurality of electric wires E and a cylindrical corrugated tube C that houses the plurality of electric wires E, and the inner corners 13 are each formed into a curved surface that follows the outer circumferential surface C1 of the corrugated tube C. With this configuration, the protector 1 and the wire harness WH, for example, allow the inner corners 13 of the case 10 to tightly contact the corrugated tube C via grease G, thereby reducing the gap between each of the inner corners 13 and the corrugated tube C. As a result, the protector 1 and the wire harness WH make it easier to spread the grease G and can suppress the occurrence of grease accumulation.

[0033] In the present embodiment, the inner corner 13 of the case 10 is formed in a curved shape along the outer peripheral surface C1 of the corrugated tube C, but the present invention is not limited to this example and may be formed in a curved shape along the outer peripheral surface of the wire E or wire bundle E1 of the wiring material W. Also, the inner corner 13 between the bottom wall 11 and the third peripheral wall 12c of the case 10 may be formed at a substantially right angle instead of being curved along the outer peripheral surface C1 of the wiring material W. Also, the protector 1 may be installed in a horizontal position, for example, with the width direction Y of the case 10 and the cover 20 aligned horizontally (the vehicle width direction).

[0034] While the embodiments of the present invention have been described above, they are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications of each configuration, shape, and the like (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
