Modes for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The exterior member of the present disclosure is as follows.

[0011] (1) It includes a cylindrical portion for passing a wiring member, and the cylindrical portion includes a first bellows portion in which first ridges and first valleys are alternately arranged in the axial direction of the cylindrical portion, and a second bellows portion in which second ridges and second valleys are alternately arranged in the circumferential direction of the cylindrical portion, and is formed of an elastic material.

[0012] (1) According to the exterior member, the first bellows portion is provided to facilitate bending the exterior member along the axial direction. By providing a second bellows portion different from the first bellows portion on the exterior member, the expandability of the exterior member is enhanced.

[0013] (2) In the exterior member of (1), the cylindrical portion includes a first cylindrical portion having a square cross-section. The first cylindrical portion includes a pair of first wall portions and a pair of second wall portions that connect the pair of first wall portions. The first bellows portion may be provided on the pair of first wall portions, and the second bellows portion may be provided on the pair of second wall portions. Thereby, the first bellows portion and the second bellows portion can be provided separately, and it is difficult for the second bellows portion to inhibit the bending of the first cylindrical portion by the first bellows portion.

[0014] (3) In the exterior member of (2), the second bellows portion is provided at an intermediate portion of the pair of second wall portions, and the first bellows portion may extend to an end portion outside the second bellows portion among the pair of second wall portions. Thereby, when the first cylindrical portion is bent at the first bellows portion, large wrinkles are less likely to occur.

[0015] (4) In the exterior member of (3), the end portion of the first trough portion may be continuous with the second trough portion. Thereby, while suppressing that the internal space becomes too small, the expandability of the exterior member can be enhanced.

[0016] (5) In the exterior member of (4), the end portion of the first peak portion may be continuous with the second peak portion. Thereby, while suppressing the protruding amount of the second peak portion on the outer surface of the exterior member, the expandability of the exterior member can be enhanced.

[0017] (6) In the exterior member of any one of (2) to (5), the cylindrical portion may include a second cylindrical portion provided with only the second bellows portion among the first bellows portion and the second bellows portion. Thereby, also for the second cylindrical portion that does not require bending along the axial direction, the expandability can be enhanced by the second bellows portion.

[0018] (7) In the exterior member of (6), the second bellows portion may be provided over the entire cylindrical portion along the axial direction. Thereby, the entire cylindrical portion along the axial direction can be expanded using the second bellows portion.

[0019] (8) Further, the wire harness of the present disclosure is a wire harness including any one of the exterior members (1) to (7), a wiring member passed through the cylindrical portion, and a connector provided at an end of the wiring member. According to this wire harness, since the expandability of the exterior member is enhanced, the connector can be enlarged.

[0020] [Details of Embodiments of the Present Disclosure] Specific examples of the exterior member and the wire harness of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0021] [Embodiment 1] Hereinafter, the exterior member and the wire harness according to Embodiment 1 will be described.

[0022] [Exterior Member] FIG. 1 is a perspective view showing an exterior member 10 according to Embodiment 1. FIG. 2 is a plan view showing the exterior member 10 according to Embodiment 1. FIG. 3 is a side view showing the exterior member 10 according to Embodiment 1. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 2. FIG. 5 is a cross-sectional view taken along line V-V of FIG. 2. FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 2.

[0023] The exterior member 10 is externally mounted on a wiring member 30 (see FIG. 7 described later). The exterior member 10 includes a cylindrical portion 12 for passing the wiring member 30. The cylindrical portion 12 is formed of an elastic material.

[0024] The cylindrical portion 12 includes a first bellows portion 15 and a second bellows portion 18. The first bellows portion 15 is a portion where first peak portions 16 and first valley portions 17 are alternately arranged in the axial direction of the cylindrical portion 12. The second bellows portion 18 is a portion where second peak portions 19 and second valley portions 20 are alternately arranged in the circumferential direction of the cylindrical portion 12. The first bellows portion 15 exhibits a waveform along the axial direction of the cylindrical portion 12, and the second bellows portion 18 exhibits a waveform along the circumferential direction of the cylindrical portion 12.

[0025] The cylindrical portion 12 includes a first cylindrical portion 21 and a second cylindrical portion 22. The first cylindrical portion 21 is a cylindrical portion provided with both the first bellows portion 15 and the second bellows portion 18. The second cylindrical portion 22 is a cylindrical portion provided with only the second bellows portion 18 out of the first bellows portion 15 and the second bellows portion 18.

[0026] A portion of the first cylindrical portion 21 where the first peak portion 16 is located may be regarded as a large-diameter cylindrical portion, and a portion where the first valley portion 17 is located may be regarded as a small-diameter cylindrical portion. The diameter of the large-diameter cylindrical portion is larger than the diameter of the small-diameter cylindrical portion. Here, the inner diameter of the large-diameter cylindrical portion is made to be about the same as the outer diameter of the small-diameter cylindrical portion. In the first cylindrical portion 21, the small-diameter cylindrical portion and the large-diameter cylindrical portion are continuously alternated in the axial direction to form the bellows shape of the first bellows portion 15. The first cylindrical portion 21 provided with the first bellows portion 15 is capable of expanding and contracting in the length direction and bending and deforming in the width direction.

[0027] The first bellows portion 15 for bending is not provided in the second cylindrical portion 22. For this reason, the second cylindrical portion 22 is more difficult to expand and contract in the length direction and bend and deform in the width direction than the first cylindrical portion 21. The second cylindrical portion 22 is a cylindrical portion in which a certain cross-sectional shape extends axially in a long shape. The length of the second cylindrical portion 22 in the axial direction is not particularly limited, but may be, for example, longer than one large-diameter cylindrical portion or small-diameter cylindrical portion in the first cylindrical portion 21.

[0028] Here, the cylindrical portion 12 has a rectangular cross-section. The cylindrical portion 12 has a pair of first wall portions 13 and a pair of second wall portions 14. The pair of second wall portions 14 connect the pair of first wall portions 13. In a state where it is arranged on the vehicle, the pair of second wall portions 14 are arranged vertically apart from each other.

[0029] As shown in FIG. 4, the cross-section of the cylindrical portion 12 may be rectangular. Here, in the cross-section of the cylindrical portion 12, the first wall portion 13 is longer than the second wall portion 14. In the rectangle of the cross-section of the cylindrical portion 12, the first wall portion 13 forms the long side, and the second wall portion 14 forms the short side. The cross-section of the cylindrical portion 12 may be square, circular, or oval, etc.

[0030] The first bellows part 15 is provided on a pair of first wall parts 13 in the first cylindrical part 21. The second bellows part 18 is provided on a pair of second wall parts 14 in the first cylindrical part 21 and a pair of second wall parts 14 in the second cylindrical part 22. The second bellows part 18 is provided at an intermediate part along the direction (the left - right direction of the paper surface in Fig. 4) connecting the pair of first wall parts 13 among the second wall parts 14. The second bellows part 18 is not provided at both end parts of the second wall parts 14 that are continuous with the first wall parts 13.

[0031] In the first cylindrical part 21, the first bellows part 15 extends to the end parts outside the second bellows part 18 among the pair of second wall parts 14. In the first cylindrical part 21, the first bellows part 15 is provided at both end parts of the pair of second wall parts 14 that are continuous with the first wall parts 13. In the circumferential direction of the first cylindrical part 21, the end part of the first bellows part 15 is connected to the second bellows part 18.

[0032] Here, in the second wall part 14, the height of the first peak part 16 and the height of the second peak part 19 are the same. However, the height of the first peak part 16 and the height of the second peak part 19 may be different. Similarly, in the second wall part 14, the depth of the first trough part 17 and the depth of the second trough part 20 are the same. However, the depth of the first trough part 17 and the depth of the second trough part 20 may be different.

[0033] In the second wall part 14, the end part of the first trough part 17 is continuous with the second trough part 20. One end part of the first trough part 17 is continuous with the second trough part 20 outside one of the pair of second wall parts 14. The other end part of the first trough part 17 is continuous with the second trough part 20 outside the other of the pair of second wall parts 14. In the cross - section at the position of the first trough part 17 shown in Fig. 4, the second wall part 14 is continuous with the first wall part 13 at the position of the second trough part 20.

[0034] In the second wall portion 14, the end of the first peak portion 16 is continuous with the second peak portion 19. One end of the first peak portion 16 is continuous with the second peak portion 19 outside one of the pair of second wall portions 14. The other end of the first peak portion 16 is continuous with the second peak portion 19 outside the other of the pair of second wall portions 14. In the cross-section at the position of the first peak portion 16 shown in FIG. 5, the second wall portion 14 is continuous with the first wall portion 13 at the position of the second peak portion 19.

[0035] The second bellows portion 18 is provided over the entire length of the cylindrical portion 12 along the axial direction. Each of the second peak portions 19 and each of the second valley portions 20 in the second bellows portion 18 are continuous over the entire length of the cylindrical portion 12 along the axial direction. However, the second bellows portion 18 may not be provided over the entire length of the cylindrical portion 12 along the axial direction. The cylindrical portion 12 may have a cylindrical portion where the second bellows portion 18 is not provided.

[0036] As shown in FIG. 6, in each of the upper and lower second wall portions 14 in the second cylindrical portion 22, the number of the second valley portions 20 is larger than the number of the second peak portions 19. Here, in each second wall portion 14, four second valley portions 20 are provided and three second peak portions 19 are provided. In the direction connecting the pair of first wall portions 13 (the left-right direction of the paper surface in FIG. 6), the second valley portions 20 are located on both outer sides of the second bellows portion 18. Therefore, the end portion of the second wall portion 14 where the second bellows portion 18 is not provided extends from the second valley portion 20 toward the first wall portion 13. However, the number of the second peak portions 19 and the number of the second valley portions 20 are not limited to the above-described numbers and can be set as appropriate. For example, the number of the second peak portions 19 may be larger than the number of the second valley portions 20, and in the second cylindrical portion 22, the end portion of the second wall portion 14 where the second bellows portion 18 is not provided may extend from the second peak portion 19 toward the first wall portion 13.

[0037] In the cross-sectional shape of the small-diameter cylindrical portion shown in Fig. 4, the arrangement of the second peak portion 19 and the second valley portion 20 is the same as that of the cross-sectional shape of the second cylindrical portion 22 shown in Fig. 6. In the cross-sectional shape of the large-diameter cylindrical portion shown in Fig. 5, the end portion of the second wall portion 14 where the second bellows portion 18 is not provided extends from the second peak portion 19 toward the first wall portion 13. In the cross-sectional shape of the large-diameter cylindrical portion shown in Fig. 5, the number of the second valley portions 20 is two less than the number of the second valley portions 20 in the cross-sectional shape of the second cylindrical portion 22 shown in Fig. 6.

[0038] Here, the period of the first bellows portion 15 (the interval between the tops of two adjacent first peak portions 16) is longer than the period of the second bellows portion 18 (the interval between the tops of two adjacent second peak portions 19). However, the period of the first bellows portion 15 may be the same as or shorter than the period of the second bellows portion 18. The length of the second cylindrical portion 22 in the axial direction may be about one to four periods of the first bellows portion 15.

[0039] The first cylindrical portion 21 and the second cylindrical portion 22 are provided at different positions from each other along the axial direction of the cylindrical portion 12. The first cylindrical portion 21 forms a part along the axial direction of the cylindrical portion 12, and the second cylindrical portion 22 forms the other part. Here, the first cylindrical portion 21 and the second cylindrical portion 22 are adjacent to each other in the axial direction. The first cylindrical portion 21 forms a part including one end portion of the cylindrical portion 12, and the second cylindrical portion 22 forms a part including the other end portion of the cylindrical portion 12. The first cylindrical portion 21 forms most of the cylindrical portion 12. The second portion may form both ends of the cylindrical portion 12, and the first cylindrical portion 21 may form the portion between the second cylindrical portions 22 at both ends. The cylindrical portion 12 may include only the first cylindrical portion 21 without including the second cylindrical portion 22.

[0040] The exterior member 10 is, for example, an injection-molded product. The exterior member 10 may be, for example, an injection-molded product made of a single material. That is, the exterior member 10 may be composed only of the elastic material that is the material of the cylindrical portion 12. The exterior member 10 may have a portion formed of a material different from the elastic material that is the material of the cylindrical portion 12 at a portion other than the cylindrical portion 12.

[0041] The elastic material that is the material of the cylindrical portion 12 is a flexible material such as rubber or elastomer. The elastic material may be, for example, an olefin-based thermoplastic elastomer (TPO) or ethylene propylene rubber (EPDM).

[0042] The thickness dimension of the wall portion in the cylindrical portion 12 is not particularly limited and can be set as appropriate. For example, the thickness dimension of the wall portion in the cylindrical portion 12 may be about 0.3 mm to 2 mm.

[0043] The length dimension of the cylindrical portion 12 is not particularly limited and can be set as appropriate according to the use and length dimension of the wiring member 30 to be passed through. For example, when the wiring member 30 is stretched between the vehicle body B and the slide door D as shown in FIG. 7, the length dimension of the cylindrical portion 12 has a length dimension that can accommodate the opening and closing of the slide door D.

[0044] <Wire harness> FIG. 7 is a perspective view showing the wire harness 100. In FIG. 7, a part of the vehicle body B and a part of the slide door D are shown by a two-dot chain line. FIG. 7 shows the front-rear direction, the up-down direction, and the inside-outside direction of the vehicle. The slide door D shown in FIG. 7 is located on the left side of the vehicle and opens and closes in the front-rear direction. In FIG. 7, the wire harness 100 shown by the solid line is in the form when the slide door D is in the closed state, and the wire harness 100 shown by the two-dot chain line is in the form when the slide door D is in the open state. FIG. 8 is a perspective view showing the exterior member 10 and the guide 40. In FIG. 8, the exterior member 10 is cut at an intermediate portion along the longitudinal direction to show the guide 40. Also, in FIG. 8, a part of the link 41 of the guide 40 is disassembled.

[0045] The wire harness 100 includes an exterior member 10, a wiring member 30, and a connector 32. The wiring member 30 is passed through the cylindrical portion 12 of the exterior member 10. The wiring member 30 is a transmission member that transmits electric power or signals. The wiring member 30 is an electric wire or an optical fiber, etc. One or a plurality of wiring members 30 are provided. The connectors 32 are provided at one end and the other end of the wiring member 30, respectively.

[0046] Here, as shown in FIG. 7, the wire harness 100 is spanned between the body B and the slide door D of the automobile. The wiring member 30 supplies power to a load or the like provided on the slide door D, and sends a signal between the load on the slide door D side and the load on the body B side. The wire harness 100 further includes a guide 40, a body fixture 50, and a door fixture 52.

[0047] The guide 40 is capable of bending and deforming according to the opening and closing of the slide door D. The wiring member 30 is passed through the guide 40. The exterior member 10 is externally mounted on the guide 40 to protect the wiring member 30 and the guide 40. The exterior member 10 and the wiring member 30 deform according to the bending deformation of the guide 40. The guide 40 is located inside the first cylindrical portion 21. The guide 40 may be the same as or smaller than the inner surface of the first cylindrical portion 21. In this case, the guide 40 does not expand the exterior member 10, and the exterior member 10 does not press the guide 40. The guide 40 includes a plurality of links 41.

[0048] Each link 41 is made of, for example, synthetic resin. Each link 41 has, for example, a cylindrical shape. The internal space of each link 41 is an insertion space for inserting the wiring member 30. As shown in FIG. 8, the plurality of links 41 are sequentially connected in a row. The internal spaces of adjacent links 41 communicate with each other. Also, adjacent links 41 are relatively rotatable.

[0049] Each link 41 has a main body cylindrical portion 42, two pairs of protruding plate portions 43, 44, a connecting protrusion 45, and a connecting hole 46. A pair of protruding plate portions 43 protrude from one side of the main body cylindrical portion 42, and a pair of protruding plate portions 44 protrude from the other side. The connecting protrusion 45 is provided on the pair of protruding plate portions 43. The protruding plate portion 43 and the protruding plate portion 44 are offset in the plate thickness direction. The connecting protrusion 45 protrudes, for example, from the main surface of the protruding plate portion 43 along the plate thickness direction toward the side where the corresponding protruding plate portion 44 is located. A connecting hole 46 is formed in each of the pair of protruding plate portions 44. The connecting hole 46 penetrates the protruding plate portion 44 in the plate thickness direction, for example. The protruding plate portion 43 of one link 41 and the protruding plate portion 44 of the adjacent pair of links 41 overlap, and the connecting protrusion 45 of one link 41 fits into the connecting hole 46 of the other link 41. Thereby, the connecting protrusion 45 and the connecting hole 46 function as a shaft portion and a bearing portion, and the adjacent pair of links 41 are rotatably connected.

[0050] The central axis of the connecting hole 46 is the rotation axis in the link 41. Here, the main body cylindrical portion 42 is square cylindrical, and the rotation axis extends in the long side direction of the main body cylindrical portion 42. In a state where the exterior member 10 is externally mounted on the guide 40, the long side direction of the first cylindrical portion 21 is along the long side direction of the main body cylindrical portion 42. The exterior member 10 bends such that the short side direction of the first cylindrical portion 21 becomes the radial direction with respect to the center of curvature.

[0051] The body fixture 50 fixes one end portion of the wire harness 100 to the body B. The door fixture 52 fixes the other end portion of the wire harness 100 to the sliding door D. For example, one end of the exterior member 10 and one end of the guide 40 are supported by the body fixture 50. One end of the wiring member 30 extends from the body fixture 50, and the connector 32 at one end is connected to the mating connector provided on the body B. For example, the other end of the exterior member 10 and the other end of the guide 40 are supported by the door fixture 52. The other end of the wiring member 30 extends from the door fixture 52, and the connector 32 at the other end is connected to the mating connector provided on the sliding door D.

[0052] The cylindrical portion 12 is formed as an elongated cylindrical shape as a whole that can surround the entire length and circumference of the guide 40. For example, the second cylindrical portion 22 is supported by the body fixture 50 and the door fixture 52. The guide 40 is passed through the exterior member 10 such that the rotation axis of the link 41 extends in the direction connecting the pair of second wall portions 14. In a state where the wire harness 100 is spanned between the body B and the slide door D, the rotation axis of the guide 40 is oriented to extend along the vertical direction. The bridging portion between the body fixture 50 and the door fixture 52 of the wire harness 100 is defined as a floating section that moves as the slide door D opens and closes.

[0053] <Method for manufacturing a wire harness> First, the end portion of the wiring member 30 is connected to the connector 32, and the guide 40 is externally fitted to the wiring member 30. Hereinafter, the one in which the end portion of the wiring member 30 is connected to the connector 32 and the guide 40 is externally fitted to the wiring member 30 is defined as the wire harness main body. When the wire harness main body is completed, next, the wire harness main body is inserted through the exterior member 10.

[0054] Here, since the exterior member 10 is not provided with a slit along the axial direction, it is impossible to cut open the exterior member 10. The exterior member 10 is expanded by a jig or the like so that the internal space expands. For example, the second cylindrical portion 22 is expanded as shown by the phantom line in FIG. 6. In this state, the wire harness main body is inserted into the exterior member 10 from one end portion. When one of the two connectors 32 comes out of the exterior member 10 and the other connector is inserted through the exterior member 10 up to the portion in front of it, the insertion of the wire harness main body into the exterior member 10 is completed. Thereafter, the expanded state of the exterior member 10 is released and returned to the state shown by the solid line in FIG. 6.

[0055] The body fixture 50 and the door fixture 52 may be attached to the wire harness main body after the insertion of the wire harness main body into the exterior member 10 is completed. The body fixture 50 and the door fixture 52 may be attached to the wire harness main body before the insertion of the wire harness main body into the exterior member 10 is completed when they can be passed through the exterior member 10.

[0056] When the wire harness main body is inserted into the exterior member 10 and the attachment between the body fixture 50 and the door fixture 52 is completed, the wire harness 100 is completed. When the wire harness 100 is arranged in the vehicle, usually, the exterior member 10 is in a non-expanded state.

[0057] <Effect, etc.> According to the exterior member 10 and the wire harness 100 configured as described above, the first bellows portion 15 is provided to facilitate bending the exterior member 10 along the axial direction. Since the exterior member 10 is provided with a second bellows portion 18 different from the first bellows portion 15, the expandability of the exterior member 10 is enhanced.

[0058] Also, the first bellows portion 15 is provided on the pair of first wall portions 13, and the second bellows portion 18 is provided on the pair of second wall portions 14. Thereby, the first bellows portion 15 can be provided separately from the second bellows portion 18, and the second bellows portion 18 is less likely to inhibit the bending of the first cylindrical portion 21 by the first bellows portion 15.

[0059] Also, the second bellows portion 18 is provided at the intermediate portion of the pair of second wall portions 14, and the first bellows portion 15 extends to the end portion outside the second bellows portion 18 among the pair of second wall portions 14. Thereby, when the first cylindrical portion 21 is bent by the first bellows portion 15, large wrinkles are less likely to occur.

[0060] Also, the end portion of the first valley portion 17 is continuous with the second valley portion 20. Thereby, while suppressing the internal space from becoming too small, the expandability of the exterior member 10 can be enhanced.

[0061] Also, the end portion of the first peak portion 16 is continuous with the second peak portion 19. Thereby, while suppressing the protruding amount of the second peak portion 19 on the outer surface of the exterior member 10, the expandability of the exterior member 10 can be enhanced.

[0062] Further, the cylindrical portion 12 includes a second cylindrical portion 22 in which only the second bellows 18 of the first bellows 15 and the second bellows 18 is provided. Thereby, even for the second cylindrical portion 22 that does not require bending along the axial direction, the expandability is enhanced by the second bellows 18.

[0063] Further, the second bellows 18 is provided along the axial direction over the entire cylindrical portion 12. Thereby, the entire cylindrical portion 12 along the axial direction can be expanded using the second bellows 18.

[0064] Further, according to the wire harness 100, since the expandability of the exterior member 10 is enhanced, the connector 32 can be enlarged.

[0065] More specifically, by enhancing the expandability of the exterior member 10, more multi-circuit wiring members 30 can be passed through the exterior member 10. For example, among the members passed through the exterior member 10, the member with the largest cross-sectional shape can be the connector 32. The cross-sectional shape of the connector 32 increases as the number of circuits of the wiring member 30 increases. By enhancing the expandability of the exterior member 10, it becomes possible to pass a larger connector 32. As shown in FIG. 6, the connector 32 may be, for example, larger than the cylindrical portion 12 in the non-expanded state and may be able to pass through the cylindrical portion 12 when the cylindrical portion 12 expands.

[0066] Furthermore, one type of exterior member 10 may be externally mounted on wire harness bodies with different numbers of circuits. That is, the same-sized exterior member 10 may be externally mounted on a plurality of types of wire harness bodies with different connector 32 sizes. In this case, when the size of the connector 32 that can be passed through one type of exterior member 10 increases, it becomes possible for one type of exterior member 10 to correspond to more types with different numbers of circuits.

[0067] [Appendix] Note that the respective configurations described in the above embodiments and respective modification examples can be appropriately combined as long as they do not contradict each other.
