[0003] [Patent Document 1] JP 2020-182322 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, electric wires to be provided in a wire harness are often prepared longer than a reference dimension. Furthermore, the prepared electric wires often vary in length. That is, the prepared electric wires often vary in the amount of excess length relative to the reference dimension. Therefore, if the prepared electric wires are used as is, there is a risk of variation in the length of the wire harness. For example, there is a risk of variation in the length of the portion of the electric wire that extends from the protector to the outside of the protector. Therefore, it has been desired to absorb the variation in the length of the electric wires in a wire harness provided with a protector.

[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The protector of the present disclosure includes: [1] A protector having a wire accommodating portion that accommodates a portion of the length of at least one electric wire therein, the wire accommodating portion having a slack absorbing portion that absorbs slack in the electric wire.

[0011] According to this configuration, the slack of the electric wire can be absorbed in the slack absorbing portion, thereby reducing the variation in the length of the portion of the electric wire that extends from the electric wire housing portion to the outside. In this way, the protector can absorb the variation in the length of the electric wire.

[0012] [2] It is preferable that the wire accommodating portion has a standard accommodating portion aligned with the slack absorbing portion in a direction in which the wire passes through the wire accommodating portion, a cross section perpendicular to the direction of passage in the internal space of the standard accommodating portion has a standard cross-sectional area corresponding to a transverse cross-sectional area of ​​the wire passing through the wire accommodating portion, and a cross section perpendicular to the direction of passage in the internal space of the slack absorbing portion has the standard cross-sectional area and an additional cross-sectional area for absorbing the slack of the wire.

[0013] According to this configuration, a cross section perpendicular to the passing direction in the internal space of the slack absorbing part has an additional cross-sectional area in addition to the reference cross-sectional area. Therefore, the cross section perpendicular to the passing direction in the internal space of the slack absorbing part has a larger area than a cross section perpendicular to the passing direction in the internal space of the reference housing part. The slack absorbing part can have a slack absorbing space that allows the path of the electric wire passing through the slack absorbing part to be lengthened within the slack absorbing part. Therefore, the length of the path of the electric wire can be changed within the slack absorbing part. That is, by arranging the electric wire so that it passes through the part corresponding to the additional cross-sectional area, the path of the part of the electric wire passing through the slack absorbing part can be lengthened. In this way, by adjusting the length of the part of the electric wire passing through the slack absorbing part, the slack of the electric wire can be easily absorbed in the slack absorbing part.

[0014] [3] A protector body having an electric wire accommodating portion with a groove-shaped accommodating recess in which a portion of the length of the electric wire is arranged and through which the electric wire passes, and a cover body covering an opening of the accommodating recess and constituting the electric wire accommodating portion together with the electric wire accommodating portion, wherein the width of the accommodating recess in the standard accommodating portion is a standard width corresponding to a cross-sectional area of ​​the electric wire passing through the electric wire accommodating portion, and the depth of the accommodating recess in the standard accommodating portion is a standard depth corresponding to the cross-sectional area, and the width of the accommodating recess in the slack absorbing portion is the standard width, and the depth of the accommodating recess in the slack absorbing portion has the standard depth plus an additional depth for absorbing the slack of the electric wire.

[0015] According to this configuration, the protector can absorb the excess length of the electric wire while preventing the protector from becoming large in the width direction of the accommodating recess. [4] It is preferable that the wire accommodating portion has two reference accommodating portions, a first reference accommodating portion extending linearly along a first axis and a second reference accommodating portion extending linearly along a second axis intersecting the first axis, and has the slack absorbing portion between the first reference accommodating portion and the second reference accommodating portion in the passing direction, and that the slack absorbing portion connects the first reference accommodating portion and the second reference accommodating portion.

[0016] According to this configuration, the slack absorbing portion is located at a portion corresponding to a bend in the electric wire accommodating portion. Therefore, the slack of the electric wire can be absorbed at a portion inside the electric wire accommodating portion where the direction of extension of the electric wire changes. Furthermore, it is easier to arrange the electric wire in the slack absorbing portion so as to absorb the slack of the electric wire, compared to a case where the slack absorbing portion extends linearly.

[0017] [5] It is preferable that the internal space of the accommodating recess in the slack absorption portion has a reference depth region, which is a region from the opening of the accommodating recess to the reference depth, and an additional depth region, which is a region from the end of the reference depth region opposite the opening to the additional depth, and that when the length of the electric wire is a reference length with no excess length, the part of the electric wire that passes through the slack absorption portion is located within the reference depth region, and when the length of the electric wire is a length that includes excess length in addition to the reference length, at least a part of the part of the electric wire that passes through the slack absorption portion is located in the additional depth region.

[0018] According to this configuration, when the length of the electric wire has an excess length, the excess length of the electric wire can be easily absorbed by disposing at least a part of the portion of the electric wire passing through the excess length absorbing portion in the additional depth region. Then, by adjusting the amount of the electric wire to be disposed in the additional depth region according to the length of the excess length of the electric wire, the path length of the electric wire in the excess length absorbing portion can be adjusted, so that excess lengths of different lengths can be easily absorbed.

[0019] [6] It is preferable that the additional depth region is a portion between the reference depth region and a bottom surface of the accommodating recess, and when the length of at least one of the electric wires is a length that includes the reference length plus a maximum length of excess length that can be absorbed in the excess length absorption portion, the portion of the at least one electric wire that passes through the excess length absorption portion is positioned in contact with the bottom surface of the accommodating recess.

[0020] With this configuration, the size of the protector in the depth direction of the accommodating recess can be reduced compared to when the portion of the electric wire having the maximum length that can be absorbed in the slack absorption section that passes through the slack absorption section does not contact the bottom surface of the accommodating recess.

[0021] The wire harness of the present disclosure includes: [7] A wire harness comprising the above protector and at least one electric wire, a portion of which in the longitudinal direction is accommodated inside the electric wire accommodating portion.

[0022] According to this configuration, in the wire harness, the protector can absorb variations in the length of the electric wires, and the same advantageous effects as those described above can be achieved. [Details of the embodiment of the present disclosure] Specific examples of the protector and wire harness of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In addition, the accompanying drawings may show components enlarged for ease of understanding. In the accompanying drawings, the dimensional ratios of the components may differ from the actual ones or from those in other drawings.

[0023] An embodiment of the protector and the wire harness will be described below. (Overall configuration of the wire harness 10) 1 and 2, the wire harness 10 includes at least one electric wire 20 and a protector 30 that protects the electric wire 20. The wire harness 10 includes, for example, three electric wires 20. The wire harness 10 is mounted on a vehicle such as an automobile. The wire harness 10 electrically connects two or more in-vehicle devices.

[0024] (Configuration of electric wire 20) 3, each electric wire 20 is, for example, an insulated electric wire having a conductive core wire 21 and an insulating coating 22 that surrounds the outer periphery of the core wire 21 and has insulating properties. Note that FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 2.

[0025] The core wire 21 may be, for example, a stranded wire made by stranding a plurality of metal wires, a columnar conductor made of a single metal rod having a solid interior, or a tubular conductor having a hollow interior. Also, the core wire 21 may be, for example, a combination of at least two of the stranded wire, the columnar conductor, and the tubular conductor. The material of the core wire 21 may be, for example, a copper-based or aluminum-based metal material.

[0026] The insulating coating 22, for example, covers the outer periphery of the core wire 21 over the entire circumferential direction around the center line L of the electric wire 20. The insulating coating 22 is made of, for example, a resin material having insulating properties.

[0027] For example, a connector (not shown) is provided at an end of each electric wire 20. The connector is electrically connected to, for example, a mating connector of an in-vehicle device. The electric wire 20 is electrically connected to the in-vehicle device via the connector.

[0028] 1, a center line L of the electric wire 20 is illustrated by a dashed line. The center line L is a line passing through the center of a cross section of the electric wire 20. A length direction X1 of the electric wire 20 is a direction in which the electric wire 20 extends and is a direction along the center line L.

[0029] The length of each electric wire 20 is either a standard length or a standard length plus an extra length. The standard length is a length that does not include an error. The extra length is a length that is added to the standard length within the tolerance range.

[0030] (Configuration of protector 30) The protector 30 accommodates a part of the electric wire 20 in the length direction X1 therein, thereby protecting the electric wire 20 arranged inside the protector 30. The protector 30 includes a protector body 31 and a cover body 32. The protector 30 is, for example, a resin molded product.

[0031] (Configuration of protector body 31) The protector body 31 has an electric wire arrangement portion 34 including an accommodating recess 33. The accommodating recess 33 is in the form of a groove through which the electric wire 20 passes. Inside the accommodating recess 33, a part of the electric wire 20 in the length direction X1 of the electric wire 20 is arranged.

[0032] Here, in the protector 30, the direction in which the electric wire 20 passes through the protector 30 is referred to as the passing direction X. The passing direction X is the same direction as the extension direction of the electric wire 20. That is, the passing direction X is a direction along the center line L. Incidentally, the passing direction X is a direction in which the electric wire 20 passes through the electric wire accommodating portion 50 described later. The arrow Y shown in the figure indicates the width direction of the accommodating recess 33. Hereinafter, the width direction of the accommodating recess 33 will be simply referred to as the "width direction Y". The width direction Y is a direction that perpendicularly intersects with the passing direction X. The arrow Z shown in the figure indicates the depth direction of the accommodating recess 33. Hereinafter, the depth direction of the accommodating recess 33 will be simply referred to as the "depth direction Z". The depth direction Z is a direction that perpendicularly intersects with the passing direction X and also perpendicularly intersects with the width direction Y. Unless otherwise specified, the directions used in the following description are directions in a state in which the parts are assembled together to form the wire harness 10.

[0033] As shown in Figs. 2 to 5, the electric wire placement section 34 has a gutter shape by having the accommodating recess 33. Fig. 4 is a cross-sectional view taken along line 4-4 in Fig. 2. Fig. 5 is a cross-sectional view taken along line 5-5 in Fig. 2. Both ends of the accommodating recess 33 in the passing direction X are open. One opening of the accommodating recess 33 in the passing direction X is a first passing opening 33a, and the other opening is a second passing opening 33b. The passing direction X is, for example, a direction from the first passing opening 33a to the second passing opening 33b.

[0034] The inner surface of the accommodating recess 33 has a bottom surface 33c and inner side surfaces 33d, 33e each extending along the passing direction X. The bottom surface 33c has, for example, a long strip shape in the passing direction X. The inner side surfaces 33d, 33e are located on both sides of the bottom surface 33c in the width direction Y. The inner side surface 33d and the inner side surface 33e face each other. The inner side surface 33d and the inner side surface 33e are, for example, parallel to each other. The width direction Y is the direction from one inner side surface 33d to the other inner side surface 33e.

[0035] The accommodating recess 33 has an opening 33f covered by the lid 32. The opening 33f is open in a direction perpendicular to the passage direction X. More specifically, the opening 33f is open in the opposite direction to the depth direction Z. The opening 33f is provided in the electric wire placement section 34 along the passage direction X from the first passage opening 33a to the second passage opening 33b. The depth direction Z is the direction from the opening 33f toward the bottom surface 33c.

[0036] As shown in Figs. 1 and 2, the protector body 31 has a first electric wire fixing portion 35 and a second electric wire fixing portion 36. The first electric wire fixing portion 35 and the second electric wire fixing portion 36 are located at both ends of the protector body 31 in the passing direction X. The first electric wire fixing portion 35 is one end of the electric wire arrangement portion 34 in the passing direction X, and protrudes from an end of the electric wire arrangement portion 34 where the first passing opening 33a is open. The second electric wire fixing portion 36 is the other end of the electric wire arrangement portion 34 in the passing direction X, and protrudes from an end of the electric wire arrangement portion 34 where the second passing opening 33b is open. The first electric wire fixing portion 35 and the second electric wire fixing portion 36 extend along the passing direction X.

[0037] As shown in FIG. 2, the wire harness 10 may include a first fixing member 11 for fixing the electric wire 20 to the first electric wire fixing portion 35. The wire harness 10 may also include a second fixing member 12 for fixing the electric wire 20 to the second electric wire fixing portion 36. The first fixing member 11 collectively surrounds a part of the electric wire 20 in the length direction X1 extending from the first passing opening 33a to the outside of the electric wire arrangement portion 34 and the first electric wire fixing portion 35. The first fixing member 11 suppresses a part of the electric wire 20 located inside the first fixing member 11 from moving relative to the first electric wire fixing portion 35. The second fixing member 12 collectively surrounds a part of the electric wire 20 in the length direction X1 extending from the second passing opening 33b to the outside of the electric wire arrangement portion 34 and the second electric wire fixing portion 36. The second fixing member 12 suppresses the movement of a portion of the electric wire 20 located on the inner side of the second fixing member 12 relative to the second electric wire fixing portion 36. As the first fixing member 11 and the second fixing member 12, for example, a cable tie or an adhesive tape can be used.

[0038] As shown in Fig. 1, the protector body 31 may have a first fixing portion 37 and a second fixing portion 38 for fixing the protector 30 to the vehicle body. The first fixing portion 37 and the second fixing portion 38 protrude from the outer surface of the electric wire arrangement portion 34 to the outside of the protector 30. The first fixing portion 37 is fixed to the vehicle body panel, for example, by being pressed into a fixing hole provided in the vehicle body panel. The second fixing portion 38 has a through hole 38a into which a bolt is inserted. The second fixing portion 38 is fixed to the vehicle body by a bolt and a nut inserted into the through hole 38a.

[0039] The protector body 31 may have a plurality of first engagement portions 39 for maintaining the cover 32 covering the opening 33f. The plurality of first engagement portions 39 protrude from the outer surface of the electric wire placement portion 34. Each of the first engagement portions 39 is located in the vicinity of the opening 33f.

[0040] (Configuration of the lid 32) 1, 2 and 3, the cover 32 is, for example, in the form of a plate extending along the passage direction X. The cover 32 is disposed on the protector body 31 so as to cover the opening 33f of the accommodation recess 33. The cover 32 is connected to the protector body 31 via, for example, a hinge 41. That is, the cover 32 and the protector body 31 may be integrally molded. The cover 32 covers the opening 33f when the hinge 41 is folded. The protector body 31 and the cover 32 may be separate bodies.

[0041] The cover 32 may have a plurality of second engagement portions 42 which respectively engage with the plurality of first engagement portions 39. The plurality of second engagement portions 42 are located at both ends of the cover 32 in the width direction Y. Each of the second engagement portions 42 engages with the corresponding first engagement portion 39 to maintain the cover 32 in a state in which the opening 33f is covered. The first engagement portions 39 and the second engagement portions 42 are engaged with each other by, for example, a snap fit.

[0042] (Configuration of electric wire housing 50) In a state where the opening 33f is covered by the lid 32, the lid 32, together with the electric wire placement portion 34, constitutes an electric wire accommodating portion 50 that accommodates a part of each electric wire 20 in the length direction X1 therein. The electric wire accommodating portion 50 is tubular through which each electric wire 20 penetrates. Each electric wire 20 passes through a space surrounded by the inner surface of the accommodating recess 33 and the inner surface of the lid 32. Furthermore, a part of each electric wire 20 in the length direction X1 is arranged in the space surrounded by the inner surface of the accommodating recess 33 and the inner surface of the lid 32. The inner surface of the lid 32 is the surface exposed to the inside of the accommodating recess 33 in the lid 32.

[0043] The electric wire accommodating portion 50 has a slack absorbing portion 51 that absorbs the slack of the electric wire 20. The electric wire accommodating portion 50 may have two reference accommodating portions, a first reference accommodating portion 52 and a second reference accommodating portion 53. Each of the first reference accommodating portion 52 and the second reference accommodating portion 53 is aligned with the slack absorbing portion 51 in the passing direction X. For example, the slack absorbing portion 51 is located between the first reference accommodating portion 52 and the second reference accommodating portion 53 in the passing direction X.

[0044] (Configuration of the first reference storage section 52) As shown in Figs. 2 and 3, the first reference accommodation portion 52 extends linearly along the first axis L1. The first axis L1 can be set arbitrarily. The first reference accommodation portion 52 has a tubular shape extending linearly along the first axis L1. The first reference accommodation portion 52 has a portion extending linearly along the first axis L1 in the electric wire placement portion 34 and a portion that closes the opening 33f of the corresponding portion in the cover body 32. For example, a predetermined area including the first passage opening 33a in the electric wire accommodation portion 50 is the first reference accommodation portion 52.

[0045] As shown in Fig. 3, a cross section perpendicular to the passing direction X in the internal space S1 of the first standard housing portion 52 has a reference cross-sectional area corresponding to the cross-sectional area of ​​the electric wire 20 passing through the electric wire housing portion 50. The reference cross-sectional area is an area having a size that does not allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X with respect to the first standard housing portion 52. However, the reference area may be an area having a size that allows the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X with respect to the first standard housing portion 52 to an extent that does not absorb the excess length of the electric wire 20. In other words, the reference area may be an area having a size that does not strictly allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X with respect to the first standard housing portion 52. Further, not only in this case, but also in a case where the reference area is an area of ​​a size that does not generally allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X relative to the first standard housing portion 52 within a range in which the operational effects of the present embodiment are achieved. In other words, the reference area is an area of ​​a size that does not allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X to an extent that the electric wire 20 absorbs the excess length of the electric wire 20 relative to the first standard housing portion 52 within a range in which the operational effects of the present embodiment are achieved. For example, the reference cross-sectional area is an area of ​​a size that maximizes the occupation area of ​​the electric wire 20 accommodated inside the first standard housing portion 52 in a cross section perpendicular to the passing direction X in the first standard housing portion 52 accommodating a part of the length direction X1 of the electric wire 20.

[0046] The cross-sectional area of ​​the internal space S1 perpendicular to the passage direction X is, for example, constant along the passage direction X. Also, the shape of the internal space S1 perpendicular to the passage direction X is, for example, constant along the passage direction X. The cross-section of the internal space S1 perpendicular to the passage direction X has, for example, a pentagonal shape.

[0047] The width W1 of the accommodating recess 33 in the first standard accommodating portion 52 is a standard width W corresponding to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating portion 50. Furthermore, the depth D1 of the accommodating recess 33 in the first standard accommodating portion 52 is a standard depth D corresponding to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating portion 50. The width W1 is the distance in the width direction Y between the inner side surface 33d and the inner side surface 33e in the first standard accommodating portion 52. The depth D1 is the distance in the depth direction Z between the opening 33f and the bottom surface 33c in the first standard accommodating portion 52.

[0048] The values ​​of the reference width W and the reference depth D are values ​​that do not allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X relative to the first reference housing portion 52. The reference width W and the reference depth D may be values ​​that do not strictly allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X relative to the first reference housing portion 52. In addition to this case, the reference width W and the reference depth D may also be values ​​that do not generally allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X relative to the first reference housing portion 52 within a range in which the effects of the present embodiment are achieved. In other words, the reference width W and the reference depth D may also be values ​​that do not allow the electric wire 20 to move in the internal space S1 in a direction intersecting the passing direction X to such an extent that the electric wire 20 absorbs the extra length of the electric wire 20 relative to the first reference housing portion 52 within a range in which the effects of the present embodiment are achieved.

[0049] For example, the reference width W and the reference depth D are set to values ​​that make the area of ​​a cross section perpendicular to the passing direction X in the internal space S1 of the first reference accommodation section 52 the reference cross-sectional area. For example, the reference width W and the reference depth D are set to values ​​that maximize the area occupied by the multiple electric wires 20 in the internal space S1 in a cross section perpendicular to the passing direction X in the internal space S1. The reference width W may be constant in the depth direction Z, or may vary depending on the position in the depth direction Z. For example, in the first reference accommodation section 52, the reference width W is a constant value in the depth direction Z. The reference depth D may be constant in the width direction Y, or may vary depending on the position in the width direction Y. For example, in the first reference accommodation section 52, the reference depth D is a constant value in the width direction Y.

[0050] 6, since the cross section perpendicular to the passing direction X in the internal space S1 has a reference cross-sectional area, the portion of each electric wire 20 disposed inside the first reference housing portion 52 is unlikely to move relative to the protector 30 in a direction perpendicular to the passing direction X. Therefore, the portion of each electric wire 20 disposed inside the first reference housing portion 52 is held by the first reference housing portion 52 in a state in which it extends linearly along the first axis L1, that is, in a state in which the center line L is parallel to the first axis L1. That is, the first reference housing portion 52 disposes the portion of each electric wire 20 disposed inside the first reference housing portion 52 linearly along the first axis L1.

[0051] Here, as shown in FIG. 3, one of the three electric wires 20 is designated as an electric wire 20a, another electric wire 20 is designated as an electric wire 20b, and the remaining electric wire is designated as an electric wire 20c. The electric wire 20a is the electric wire 20 that is closest to the inner surface 33d and closest to the inner surface of the cover body 32 among the three electric wires 20. The electric wire 20b is the electric wire 20 that is closest to the inner surface 33e among the three electric wires 20. The electric wire 20c is the electric wire 20 that is closest to the inner surface 33d and closest to the bottom surface 33c among the three electric wires 20. A part of the electric wire 20a in the length direction X1 is arranged inside the first reference housing portion 52, for example, in a state in contact with the inner surface 33d and the electric wires 20b and 20c. A part of the electric wire 20b in the length direction X1 is arranged inside the first reference housing portion 52, for example, in a state in contact with the inner surface 33e and the electric wire 20a. A portion of the electric wire 20c in the length direction X1 is disposed inside the first reference accommodation portion 52 in a state of contacting, for example, the bottom surface 33c, the inner surface 33d, and the electric wire 20a.

[0052] (Configuration of the second reference storage section 53) As shown in FIG. 2 and FIG. 5, the second reference housing portion 53 extends linearly along a second axis L2 intersecting with the first axis L1. The second axis L2 can be set arbitrarily as long as it intersects with the first axis L1. For example, the second axis L2 intersects with the first axis L1 perpendicularly. The second reference housing portion 53 has a tubular shape extending linearly along the second axis L2. The second reference housing portion 53 has a portion extending linearly along the second axis L2 in the electric wire placement portion 34 and a portion that closes the opening 33f of the portion in the cover body 32. For example, a predetermined area including the second passage opening 33b in the electric wire housing portion 50 is the second reference housing portion 53.

[0053] As shown in FIG. 5, a cross section perpendicular to the passing direction X in the internal space S2 of the second standard accommodating section 53 has a reference cross-sectional area according to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating section 50, similar to a cross section perpendicular to the passing direction X in the internal space S1 of the first standard accommodating section 52. The width W2 of the accommodating recess 33 in the second standard accommodating section 53 is a reference width according to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating section 50. The depth D2 of the accommodating recess 33 in the second standard accommodating section 53 is a reference depth according to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating section 50. The reference cross-sectional area, reference width, and reference depth in the second standard accommodating section 53 are set in the same spirit as the reference area, reference width W, and reference depth D in the first standard accommodating section 52. Therefore, detailed explanation of the reference cross-sectional area, reference width, and reference depth in the second standard accommodating section 53 will be omitted.

[0054] The reference cross-sectional area of ​​the cross section perpendicular to the passage direction X in the internal space S2 may be the same as or different from the reference cross-sectional area of ​​the cross section perpendicular to the passage direction X in the internal space S1. For example, the reference cross-sectional area of ​​the cross section perpendicular to the passage direction X in the internal space S2 is smaller than the reference cross-sectional area of ​​the cross section perpendicular to the passage direction X in the internal space S1. The reference width of the second reference accommodation section 53 may be the same as or different from the reference width W of the first reference accommodation section 52. For example, the reference width of the second reference accommodation section 53 is the same as the reference width W of the first reference accommodation section 52. The reference depth of the second reference accommodation section 53 may be the same as or different from the reference depth D of the first reference accommodation section 52.

[0055] The cross-sectional area of ​​the internal space S2 perpendicular to the passage direction X is, for example, constant along the passage direction X. Also, the shape of the internal space S2 perpendicular to the passage direction X is, for example, constant along the passage direction X. The cross-section of the internal space S2 perpendicular to the passage direction X has, for example, a rectangular shape.

[0056] A portion of the electric wire 20a in the longitudinal direction X1 is disposed inside the second reference accommodating portion 53, for example, in a state of contact with the inner side surface 33d and the electric wires 20b and 20c. A portion of the electric wire 20b in the longitudinal direction X1 is disposed inside the second reference accommodating portion 53, for example, in a state of contact with the inner side surface 33e and the electric wire 20a. A portion of the electric wire 20c in the longitudinal direction X1 is disposed inside the second reference accommodating portion 53, for example, in a state of contact with the bottom surface 33c, the inner side surface 33d, and the electric wire 20a.

[0057] (Configuration of slack absorbing portion 51) 2 and 4, the slack absorbing portion 51 connects the first reference accommodating portion 52 and the second reference accommodating portion 53. Since the first axis L1 and the second axis L2 intersect, the slack absorbing portion 51 corresponds to, for example, a bending corner between the first reference accommodating portion 52 and the second reference accommodating portion 53 in the electric wire accommodating portion 50. The electric wire accommodating portion 50 has, for example, an L-shaped tubular shape.

[0058] The slack absorbing portion 51 has a tubular shape extending along the passage direction X between the first reference accommodating portion 52 and the second reference accommodating portion 53. The slack absorbing portion 51 has a portion between a portion extending linearly along the first axis L1 and a portion extending linearly along the second axis L2 in the electric wire arrangement portion 34, and a portion that closes the opening 33f in the portion in the cover body 32 between the portions.

[0059] 4, a cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 has a reference cross-sectional area corresponding to the transverse cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating portion 50, and an additional cross-sectional area for absorbing the slack of the electric wire 20. For example, a cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 has a reference cross-sectional area in the first standard accommodating portion 52 and an additional cross-sectional area. A cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 may have a reference cross-sectional area in the second standard accommodating portion 53 and an additional cross-sectional area.

[0060] In FIG. 4, a dot is added to the portion corresponding to the reference cross-sectional area in the first reference housing portion 52. In a cross section perpendicular to the passing direction X in the internal space S3, the area of ​​the range from the inner surface of the cover body 32 to just before the bottom surface 33c corresponds to the reference cross-sectional area. In a cross section perpendicular to the passing direction X in the internal space S3, the area of ​​the range between the portion corresponding to the reference cross-sectional area and the bottom surface 33c corresponds to the additional cross-sectional area. Therefore, the cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 has a cross-sectional area larger than the cross section perpendicular to the passing direction X in the internal space S3 of the first reference housing portion 52 and the cross section perpendicular to the passing direction X in the internal space S2 of the second reference housing portion 53. In other words, the slack absorbing portion 51 is a portion of the electric wire housing portion 50 whose cross section perpendicular to the passing direction X in the internal space has an area larger than the reference cross-sectional area. The slack absorbing portion 51 is a portion in the electric wire accommodating portion 50, in which the area of ​​a cross section perpendicular to the passage direction X in the internal space is larger than the reference cross-sectional area to an extent that enables the path of the electric wire 20 to be changed in the internal space. The cross section perpendicular to the passage direction X in the internal space S3 has, for example, a rectangular shape.

[0061] The width W3 of the accommodating recess 33 in the slack absorbing portion 51 is, for example, a reference width W. Furthermore, the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 has a reference depth D and an additional depth Da for absorbing the slack of the electric wire 20. That is, the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 is a depth obtained by adding the additional depth Da to the reference depth D. The additional depth Da sets the size of the internal space S3 in the depth direction Z to a size that allows the path of the electric wire 20 to be changed. Since the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 has the additional depth Da in addition to the reference depth D, the electric wire 20 can move in the slack absorbing portion 51 in a direction perpendicular to the passing direction X, more specifically, in the depth direction Z.

[0062] The internal space S3 of the slack absorbing portion 51 is, for example, the same as the internal space of the accommodating recess 33 in the slack absorbing portion 51. The internal space of the accommodating recess 33 in the slack absorbing portion 51 has a reference depth region A1, which is a region from the opening 33f of the accommodating recess 33 to the reference depth D, and an additional depth region A2, which is a region from the end opposite the opening 33f in the reference depth region A1 to the additional depth Da. The additional depth region A2 is, for example, a portion between the reference depth region A1 and the bottom surface 33c of the accommodating recess 33. In FIG. 4, the reference depth region A1 corresponds to the region with dots. Also, in FIG. 4, the additional depth region A2 corresponds to the region with no dots between the reference depth region A1 and the bottom surface 33c in the internal space S3.

[0063] (Arrangement of the electric wire 20 in the slack absorbing portion 51 when the length of the electric wire 20 is the reference length) 4 and 6, when the length of each electric wire 20 is a reference length that does not include an excess length, the portion of the electric wire 20 that passes through the excess length absorbing portion 51 is disposed within the reference depth region A1. At this time, the electric wire 20 that passes through the excess length absorbing portion 51 has the shortest path length within the excess length absorbing portion 51. The electric wire 20 that passes through the excess length absorbing portion 51 is disposed in a straight line.

[0064] (Arrangement of the electric wire 20 in the slack absorbing portion 51 when the length of the electric wire 20 includes a slack portion) As shown in Fig. 4 and Fig. 7, when the length of the electric wire 20 is a length including an excess length in addition to the reference length, at least a part of the part of the electric wire 20 passing through the slack absorbing part 51 is arranged in the additional depth region A2. In Fig. 4, the electric wire 20 having a length including an excess length is illustrated by a two-dot chain line. When at least a part of the part of the electric wire 20 passing through the slack absorbing part 51 is arranged in the additional depth region A2, the electric wire 20 in the slack absorbing part 51 is arranged in a detour away from the cover 32 and close to the bottom surface 33c. Therefore, the path length of the electric wire 20 passing through the slack absorbing part 51 is longer than when the electric wire 20 is arranged in the reference depth region A1. The path length of the electric wire 20 passing through the slack absorbing part 51 is longer as the electric wire 20 approaches the bottom surface 33c in the depth direction Z.

[0065] For example, when the length of the electric wire 20b is a length that includes the standard length plus the maximum length of excess length that can be absorbed in the excess length absorbing section 51, the portion of the electric wire 20b that passes through the excess length absorbing section 51 is positioned in contact with the bottom surface 33c of the accommodating recess 33.

[0066] In addition, the electric wire 20 is pushed closer to the bottom surface 33c by an operator who attaches the protector 30 to the electric wire 20, so that at least a part of the electric wire 20 is disposed in the additional depth region A2. Then, the electric wire 20 is fixed to the protector 30 by the first fixing member 11 and the second fixing member 12, so that the electric wire 20 is maintained in a state in which the excess length is absorbed.

[0067] The effects of this embodiment will be described. (1) The protector 30 includes a wire accommodating portion 50 that accommodates a part of the wire 20 in the length direction X1. The wire accommodating portion 50 includes a slack absorbing portion 51 that absorbs the slack of the wire 20.

[0068] According to this configuration, the slack of the electric wire 20 can be absorbed in the slack absorbing portion 51. Therefore, it is possible to reduce the variation in the length of the portion of the electric wire 20 extending outward from the electric wire accommodating portion 50. In this manner, the protector 30 can absorb the variation in the length of the electric wire 20.

[0069] In general, a high-voltage electric wire used when supplying a high voltage such as a hundred and several tens of volts to a few hundreds of volts has a larger diameter than a low-voltage electric wire used when supplying a low voltage of a few volts to a dozen volts. Therefore, a high-voltage electric wire has higher rigidity than a low-voltage electric wire. When such a high-voltage electric wire has an excess length, even if the electric wire is pushed into a conventional protector that does not have an excess length absorbing portion 51 so as to absorb the excess length, there is a concern that the electric wire will jump out of the protector along the passing direction. In contrast, in this embodiment, since the protector 30 has the excess length absorbing portion 51, there is a space inside the protector 30 for arranging the excess length of the electric wire 20. Therefore, when the electric wire 20 is such a high-voltage electric wire, even if the electric wire 20 is arranged in the protector 30 in a state where it is bent into an L-shape, it is possible to prevent the electric wire 20 from jumping out in the passing direction X from at least one of the first passing opening 33a and the second passing opening 33b.

[0070] (2) The electric wire accommodating portion 50 has a first standard accommodating portion 52 and a second standard accommodating portion 53 aligned with the slack absorbing portion 51 in the passing direction X in which the electric wire 20 passes through the electric wire accommodating portion 50. A cross section perpendicular to the passing direction X in the internal space S1 of the first standard accommodating portion 52 has a standard cross-sectional area corresponding to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating portion 50. A cross section perpendicular to the passing direction X in the internal space S2 of the second standard accommodating portion 53 has a standard cross-sectional area corresponding to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating portion 50. A cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 has the standard cross-sectional area and an additional cross-sectional area for absorbing the slack of the electric wire 20.

[0071] According to this configuration, the cross section perpendicular to the passing direction X in the internal space S3 has an additional cross-sectional area in addition to the reference cross-sectional area. Therefore, the cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing part 51 has a larger area than the cross section perpendicular to the passing direction X in the internal space S1 of the first reference housing part 52. Also, the cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing part 51 has a larger area than the cross section perpendicular to the passing direction X in the internal space S2 of the second reference housing part 53. Then, the slack absorbing part 51 can have a slack absorbing space that enables the path of the electric wire 20 passing through the slack absorbing part 51 to be lengthened within the slack absorbing part 51. Therefore, the electric wire 20 can change the path length within the slack absorbing part 51. That is, by arranging the electric wire 20 so that it passes through the part corresponding to the additional cross-sectional area, the path of the part of the electric wire 20 passing through the slack absorbing part 51 can be lengthened. In this manner, by adjusting the length of the portion of the electric wire 20 passing through the slack absorbing portion 51 , the slack of the electric wire 20 can be easily absorbed by the slack absorbing portion 51 .

[0072] (3) The protector 30 includes a protector body 31 and a lid 32. The protector body 31 has an electric wire arrangement section 34 in which a part of the electric wire 20 in the length direction X1 is arranged and which includes a groove-shaped accommodating recess 33 through which the electric wire 20 passes. The lid 32 covers an opening 33f of the accommodating recess 33 and configures the electric wire accommodating section 50 together with the electric wire arrangement section 34. The width W1 of the accommodating recess 33 in the first standard accommodating section 52 is a reference width W according to the cross-sectional area of ​​the electric wire 20 passing through the electric wire accommodating section 50. The depth D1 of the accommodating recess 33 in the first standard accommodating section 52 is a reference depth D according to the cross-sectional area of ​​the electric wire 20. The width W3 of the accommodating recess 33 in the slack absorbing section 51 is the reference width W, and the depth D3 of the accommodating recess 33 in the slack absorbing section 51 has the reference depth D and an additional depth Da for absorbing the slack of the electric wire 20.

[0073] According to this configuration, the excess length of the wires 20 can be absorbed by the protector 30 while preventing the protector 30 from becoming large in size in the width direction Y of the accommodating recess 33. Furthermore, the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 can be changed according to the length of the slack of the electric wire 20 to be absorbed in the slack absorbing portion 51 without changing the shape of the lid 32. Therefore, when the protector body 31 and the lid 32 are separate bodies, even if the molding die for molding the protector body 31 is changed, the molding die for molding the lid 32 does not need to be changed. As a result, the manufacturing cost of the protector 30 can be reduced.

[0074] (4) The electric wire accommodating portion 50 has two reference accommodating portions: a first reference accommodating portion 52 extending linearly along the first axis L1, and a second reference accommodating portion 53 extending linearly along a second axis L2 intersecting the first axis L1. Furthermore, the electric wire accommodating portion 50 has a slack absorbing portion 51 between the first reference accommodating portion 52 and the second reference accommodating portion 53 in the passing direction X. The slack absorbing portion 51 connects the first reference accommodating portion 52 and the second reference accommodating portion 53.

[0075] According to this configuration, the slack absorbing portion 51 is located at a portion corresponding to a bend in the electric wire accommodating portion 50. Therefore, the slack of the electric wire 20 can be absorbed at a portion inside the electric wire accommodating portion 50 where the extending direction of the electric wire 20 changes. Then, it becomes easier to arrange the electric wire 20 in the slack absorbing portion 51 so as to absorb the slack of the electric wire 20, compared to a case where the first reference accommodating portion 52, the second reference accommodating portion 53, and the slack absorbing portion 51 extend along a single linear axis.

[0076] (5) The internal space of the accommodating recess 33 in the slack absorbing portion 51 has a reference depth region A1, which is a region from the opening 33f of the accommodating recess 33 to the reference depth D, and an additional depth region A2, which is a region from the end of the reference depth region A1 opposite the opening 33f to the additional depth Da. When the length of the electric wire 20 is a reference length that does not include an excess length, the portion of the electric wire 20 that passes through the slack absorbing portion 51 is disposed within the reference depth region A1. When the length of the electric wire 20 is a length that includes an excess length in addition to the reference length, at least a part of the portion of the electric wire 20 that passes through the slack absorbing portion 51 is disposed in the additional depth region A2.

[0077] According to this configuration, when the length of the electric wire 20 includes an excess length, by disposing at least a part of the portion of the electric wire 20 passing through the excess length absorbing portion 51 in the additional depth region A2, the excess length of the electric wire 20 can be easily absorbed. By adjusting the amount of the electric wire 20 to be disposed in the additional depth region A2 according to the excess length of the electric wire 20, the path length of the electric wire 20 in the excess length absorbing portion 51 can be adjusted, so that excess lengths of different lengths can be easily absorbed.

[0078] (6) The additional depth region A2 is a portion between the reference depth region A1 and the bottom surface 33c of the accommodating recess 33. When the length of the electric wire 20b is equal to the reference length plus the maximum length of excess length that can be absorbed in the excess length absorbing portion 51, the portion of the electric wire 20b that passes through the excess length absorbing portion 51 is disposed in contact with the bottom surface 33c of the accommodating recess 33.

[0079] According to this configuration, when the length of the electric wire 20b is a length that has the maximum excess length that can be absorbed in the excess length absorbing section 51, the size of the protector 30 in the depth direction Z can be prevented from increasing compared to when the part of the electric wire 20b that passes through the excess length absorbing section 51 does not contact the bottom surface 33c of the accommodating recess 33.

[0080] (7) The wire harness 10 includes the protector 30 and at least one electric wire 20, a part of which in the length direction X1 is accommodated inside the electric wire accommodating portion 50. According to this configuration, in the wire harness 10 including the protector 30, the protector 30 can absorb variations in the length of the electric wires 20.

[0081] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. When the length of the electric wire 20b is a standard length plus the maximum length that can be absorbed in the slack absorbing section 51, the portion of the electric wire 20b passing through the slack absorbing section 51 does not need to contact the bottom surface 33c of the accommodating recess 33.

[0082] The second axis L2 may intersect with the first axis L1 at an angle other than 90°. For example, the second axis L2 may intersect with the first axis L1 at an angle such that the electric wire receiving portion 50 forms a V-shaped tube.

[0083] The electric wire receiving portion 50 does not necessarily have to have either the first reference receiving portion 52 or the second reference receiving portion 53. The width W3 and the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 may be set based on the reference width and reference depth of the second reference accommodating portion 53 .

[0084] In the above embodiment, the width W3 of the accommodating recess 33 in the slack absorbing portion 51 is the reference width W. The depth D3 of the accommodating recess 33 in the slack absorbing portion 51 is the reference depth D plus the additional depth Da. However, the width W3 of the accommodating recess 33 in the slack absorbing portion 51 may be the reference width W plus the additional width for absorbing the slack of the electric wire 20. In this case, the depth D3 of the accommodating recess 33 in the slack absorbing portion 51 may be the reference depth D or the reference depth D plus the additional depth Da. In this way, the cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51 is larger in the width direction Y than at least the cross section perpendicular to the passing direction X in the internal space S1 of the first reference accommodating portion 52. That is, in the cross section perpendicular to the passing direction X in the internal space S3 of the slack absorbing portion 51, the additional cross-sectional area is added to the side of the reference cross-sectional area in the width direction Y. Even in this manner, the slack of the electric wire 20 can be absorbed in the slack absorbing portion 51 .

[0085] The shape of the first reference accommodating portion 52 is not limited to the shape in the above embodiment. The first reference accommodating portion 52 may have any shape as long as it can surround the outer circumference of at least one electric wire 20. For example, the shape of a cross section perpendicular to the passing direction X in the internal space S1 of the first reference accommodating portion 52 may be changed to any of a polygonal shape, a circular shape, an elliptical shape, a rounded rectangular shape, and any other arbitrary shape. The shape of the second reference accommodating portion 53 and the shape of the slack absorbing portion 51 may also be changed in a similar manner.

[0086] The electric wire housing 50 may have a plurality of slack absorbing portions 51. The electric wire housing 50 may have three or more reference housing portions. The shape of the protector 30 is not limited to that of the above embodiment. For example, the protector 30 may be composed of one tubular part. Also, for example, the protector 30 may not have either the first fixing portion 37 or the second fixing portion 38.

[0087] In the above embodiment, the passing direction X is the direction from the first passing opening 33a to the second passing opening 33b. However, the passing direction X may be the direction from the second passing opening 33b to the first passing opening 33a. Also, in the above embodiment, the width direction Y is the direction from the inner side surface 33d to the inner side surface 33e. However, the width direction Y may be the direction from the inner side surface 33e to the inner side surface 33d.

[0088] The wire harness 10 may include a plurality of protectors 30. The number of electric wires 20 included in the wire harness 10 is not limited to three, and may be one, two, or four or more. When the wire harness 10 includes a plurality of electric wires 20, the plurality of electric wires 20 may be different types of electric wires.

[0089] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
