Embodiments for Carrying Out the Invention

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The movable path regulating component for an electric wire of the present disclosure is as follows.

[0012] (1) A movable path regulating component for an electric wire that regulates the movable paths of at least one first electric wire and at least one second electric wire spanned between a first component and a second component that moves relative to the first component, the movable path regulating component for an electric wire including a main body component that is rotatably connected to another movable path regulating component for an electric wire, and a lid component that is separate from the main body component and is attached to the main body component. The main body component has an opening for accommodating the first electric wire and a first electric wire accommodation space that accommodates the at least one first electric wire in a penetrating state on the back side of the accommodation opening. The lid component has a lid main body portion that closes the accommodation opening and an additional enclosure portion that forms a second electric wire accommodation space for accommodating the at least one second electric wire in a penetrating state. The second electric wire accommodation space is partitioned from the first electric wire accommodation space by the lid main body portion.

[0013] According to this wire movable path regulating component, even if a second wire is added, the first wire based on the basic design is path-regulated within the first wire accommodation space. Therefore, the addition of the second wire hardly affects the movement of the first wire. Further, the second wire is path-regulated within a second wire accommodation space partitioned from the first wire accommodation space. The first wire is path-regulated within the first wire accommodation space, and separately from this, the second wire is path-regulated within the second wire accommodation space. Therefore, a change in the path length corresponding to a change in the paths of the first wire and the second wire is reduced. Thereby, variations in the loads acting on the first wire and the second wire when the paths of the first wire and the second wire change are reduced.

[0014] (2) The wire movable path regulating component according to (1), wherein the number of at least one second wire accommodated in the second wire accommodation space may be less than the number of at least one first wire accommodated in the first wire accommodation space. In this case, it is possible to easily add a smaller number of second wires.

[0015] (3) The wire movable path regulating component according to (1) or (2), wherein the main body component has locking portions located on both side portions of the accommodation opening, the lid main body component has a locked portion to which the locking portions are locked, and the additional enclosure portion may be located inside the locked portion. Thereby, the locked portion can be easily die-formed.

[0016] (4) The wire movable path regulating component according to any one of (1) to (3), wherein the lid component may have regulation shape surface symmetry with respect to a plane orthogonal to the width direction and regulation shape surface symmetry with respect to a plane orthogonal to the penetrating direction of the second wire accommodation space. Thereby, since the lid component can be attached to the main body component without worrying about the orientation, the assembly workability of the wire movable path regulating component is improved.

[0017] (5) A movable path regulating component for an electric wire according to any one of (1) to (4), wherein the length of the additional enclosure portion in the penetrating direction of the second electric wire accommodating space may gradually decrease as it moves away from the main body component. Thereby, when the movable path regulating component for an electric wire rotates with respect to another movable path regulating component for an electric wire, the additional enclosure portion is less likely to interfere with the other movable path regulating component for an electric wire.

[0018] (6) A movable path regulating component for an electric wire according to any one of (1) to (5), wherein a portion of the additional enclosure portion on the side opposite to the main body component may be formed in an arc shape when viewed along the penetrating direction of the second electric wire accommodating space. In this way, when a portion of the additional enclosure portion on the side opposite to the main body component is in an arc shape, it is easy to cover the movable path regulating component for an electric wire with an exterior component such as a rubber boot.

[0019] The path regulating wire harness of the present disclosure is as follows.

[0020] (7) A path regulating wire harness including a plurality of movable path regulating components for electric wires according to any one of (1) to (6), the at least one first electric wire, and the at least one second electric wire, wherein the plurality of movable path regulating components for electric wires are connected in a row so as to be rotatable relative to each other, the at least one first electric wire is accommodated in the plurality of movable path regulating components through the first electric wire accommodating space, and the at least one second electric wire is accommodated in the plurality of movable path regulating components through the second electric wire accommodating space.

[0021] Thereby, it is possible to easily cope with the addition of electric wires, and in the path regulating wire harness, when the paths of the first electric wire and the second electric wire change, variations in the loads acting on the first electric wire and the second electric wire are reduced.

[0022] [Details of Embodiments of the Present Disclosure] Specific examples of the movable path restricting component for an electric wire and the path restricting wire harness of the present disclosure will be described below with reference to the drawings. Note 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.

[0023] [Embodiment] Hereinafter, the movable path restricting component for an electric wire and the path restricting wire harness according to the embodiment will be described.

[0024] [Example of Application Target of Path Restricting Wire Harness] FIG. 1 is a schematic plan view showing a state in which a path restricting wire harness 20 is disposed between a vehicle body main body 10 and a slide door 14. In FIG. 1, the movement path of the slide door 14 when the slide door 14 is opened and closed is indicated by an arrow A. Further, the state change of the path restricting wire harness 20 accompanying the opening and closing of the slide door 14 is indicated by a two-dot chain line.

[0025] The relationship between the vehicle body main body 10 and the slide door 14 will be described. An automobile includes a vehicle body main body 10 and a slide door 14 provided on one side portion of the vehicle body main body 10. A boarding opening 11 through which a person can get on and off is provided on one side portion of the vehicle body main body 10. The slide door 14 is supported between a position (closed position P1) for closing the boarding opening 11 and a position (open position P2) for opening the boarding opening 11 by a slide support mechanism portion including a guide rail 12 and a movable support portion or the like that supports the slide door 14 in a movable state along the guide rail 12. In the present embodiment, the closed position P1 is located rearward of the open position P2.

[0026] The slide door 14 slides laterally of the vehicle body main body 10 to open and close the boarding opening 11. Here, the slide door 14 slides from the closed position P1 toward the open position P2 while being displaced outward in the vehicle width direction (see arrow A). The vehicle body main body 10 is an example of a first component, and the slide door 14 is an example of a second component that moves relative to the vehicle body main body 10.

[0027] The path regulation wire harness 20 is laid between the vehicle body main body 10 and the sliding door 14 as described above. When the sliding door 14 moves relative to the vehicle body main body 10, the path regulation wire harness 20 moves along with the movement of the sliding door 14. The movement range of the path at this time is regulated by the movable path regulation parts 30 for electric wires. Thereby, it is possible to prevent the path regulation wire harness 20 from interfering with the peripheral edge of the boarding opening 11 of the vehicle body main body 10 and the sliding door 14.

[0028] The first part and the second part to which the path regulation wire harness 20 is laid are not limited to the above example. The path regulation wire harness 20 is laid between the first part and the second part that moves relative to the first part. For example, the first part may be a vehicle body (for example, a floor), and the second part may be a sliding seat.

[0029] <Regarding the path regulation wire harness> FIG. 2 is a perspective view showing a part of the path regulation wire harness 20, and FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2. In FIG. 3, the state where the connected movable path regulation parts 30 for electric wires are rotated is shown by a two-dot chain line.

[0030] As shown in FIGS. 1 to 3, the path regulation wire harness 20 includes a plurality of movable path regulation parts 30 for electric wires, at least one first electric wire 22, and at least one second electric wire 24. In FIG. 2, a plurality of first electric wires 22 are shown as one bundle.

[0031] A plurality of movable path regulation parts 30 for electric wires are connected in a row so as to be rotatable relative to each other. In the present embodiment, adjacent movable path regulation parts 30 for electric wires are connected so as to be rotatable around one axis. For this reason, adjacent movable path regulation parts 30 for electric wires are in a state where rotation around an axis different from the one axis is regulated. By connecting a plurality of movable path regulation parts 30 for electric wires so as to be rotatable around an axis parallel to the one axis, the plurality of movable path regulation parts 30 for electric wires are connected so as to be able to bend on one plane, and bending in a direction hanging down from the one plane is suppressed.

[0032] Further, the rotation range around one axis is restricted between adjacent movable path regulating parts 30 for electric wires. Thereby, the bending direction and the bending range of the plurality of movable path regulating parts 30 for electric wires on the one plane are restricted. The configuration for restricting this rotation range will be described later.

[0033] The movable path regulating part 30 for electric wires has a first electric wire accommodating space 36 and a second electric wire accommodating space 64. The first electric wire accommodating space 36 and the second electric wire accommodating space 64 are adjacent to each other in a partitioned state.

[0034] The first electric wire 22 is a wiring member that electrically connects the electric parts on the vehicle body main body 10 side and the electric parts on the slide door 14 side. The first electric wire 22 may be one or a plurality of wires. The second electric wire 24 is a wiring member that electrically connects the electric parts on the vehicle body main body 10 side and the electric parts on the slide door 14 side. The second electric wire 24 may be one or a plurality of wires. The first electric wire 22 has, for example, a core wire 22a and an insulating coating 22b that covers the core wire 22a. The second electric wire 24 has, for example, a core wire 24a and an insulating coating 24b that covers the core wire 24a.

[0035] The first electric wire 22 is assumed to be a wiring material that connects the electric parts installed in the basic design stage of the automobile, for example. The second electric wire 24 is assumed to be a wiring material that is connected to the electric parts added by equipment addition or the like after the basic design stage of the automobile. For this reason, it is assumed that the number of the second electric wires 24 is smaller than the number of the first electric wires 22.

[0036] The first electric wire 22 is accommodated through each first electric wire accommodating space 36 in a plurality of movable path regulating parts 30 for electric wires arranged in a row. The second electric wire 24 is accommodated through each second electric wire accommodating space 64 in a plurality of movable path regulating parts 30 for electric wires arranged in a row. For this reason, the first electric wire 22 and the second electric wire 24 are path-regulated in separate spaces 36 and 64 of the plurality of movable path regulating parts 30 for electric wires while maintaining a parallel state.

[0037] The first electric wire 22 and the second electric wire 24 may be signal wires or power wires. The plurality of first electric wires 22 may be bundled in the form of a stranded wire or may be bundled in a state covered within a sheath. Similarly, the plurality of second electric wires 24 may also be bundled by being stranded or covered with a sheath. Further, the first electric wire 22 and the second electric wire 24 may include coaxial cables.

[0038] <Regarding the movable path regulating component for electric wires> The movable path regulating component 30 for electric wires will be described. FIG. 4 is an exploded perspective view showing the movable path regulating component 30 for electric wires. FIG. 5 is a At one end of FIG. 2 V-V cross-sectional view.

[0039] The movable path regulating component 30 for electric wires includes a main body component 32 and a lid component 50. The main body component 32 and the lid component 50 are components separately injection-molded with resin, for example.

[0040] The main body component 32 is rotatably connected to the main body component 32 of another movable path regulating component 30 for electric wires. The main body component 32 has a housing opening 38 and a first electric wire housing space 36. The housing opening 38 is an opening for housing the first electric wire 22 within the main body component 32. The first electric wire housing space 36 is a space for housing the first electric wire 22 in a penetrating state on the back side of the housing opening 38.

[0041] More specifically, the main body component 32 is a component integrally injection-molded with resin and includes a bottom piece 34 and a pair of side pieces 40.

[0042] The side piece 40 is formed in an elongated plate shape. A connecting recess 41 is formed at one end in the longitudinal direction of the side piece 40. In the present embodiment, the connecting recess 41 is a round through hole. The outer peripheral edge at one end in the longitudinal direction of the side piece 40 is formed into an arcuate edge 42 that protrudes outward.

[0043] A connecting protrusion 44 is formed on the outer-facing surface of the other end in the longitudinal direction of the side piece 40. In the present embodiment, the connecting protrusion 44 is a short cylindrical protrusion. The connecting protrusions 44 at the other ends in the longitudinal direction of the pair of side pieces 40 are fitted into the connecting recesses 41 at one ends in the longitudinal direction of the other pair of side pieces 40. Thereby, a plurality of adjacent main body parts 32 are connected so as to be rotatable around the central axis of the pair of connecting protrusions 44.

[0044] A guide surface 44g is formed on a portion of the tip surface of the connecting protrusion 44 closer to the other end in the longitudinal direction of the side piece 40, and the protruding length decreases as it goes toward the other end in the longitudinal direction of the side piece 40. For this reason, one end of the side piece 40 can easily ride onto the connecting protrusion 44 of the other side piece 40 by using the guide surface 44g of the connecting protrusion 44. Thereby, the connecting protrusion 44 can be easily fitted into the connecting recess 41.

[0045] The outer-facing surface of the other end in the longitudinal direction of the side piece 40 is recessed more than the outer-facing surface of one end in the longitudinal direction of the side piece 40. Thereby, when the One end is overlapped with the The other end outer surface of the other side piece 40, the step between the outer surface of one end of the side piece 40 and the One end outer surface of the other side piece 40 can be reduced.

[0046] The outer peripheral edge of the other end in the longitudinal direction of the side piece 40 is formed in a shape that restricts the rotation range with respect to the other side piece 40. In the present embodiment, the outer peripheral edge of the other end in the longitudinal direction of the side piece 40 has a first restricting edge 46a along the longitudinal direction of the side piece 40 and a second restricting edge 46b inclined with respect to the longitudinal direction of the side piece 40. The first restricting edge 46a and the second restricting edge 46b face opposite to each other.

[0047] When the connecting protrusion 44 is fitted into the connecting recess 41, the two side pieces 40 are connected. When the two side pieces 40 extend linearly, the first regulating edge 46a of one side piece 40 contacts the inward protrusion 45 of the other side piece 40 (the state shown by the solid line in FIG. 3). When the two side pieces 40 rotate relative to each other, the second regulating edge 46b of one side piece 40 contacts the bottom piece 34 of the other side piece 40 (the state shown by the two-dot chain line in FIG. 3). Therefore, the rotation range of the two side pieces 40 is restricted to the range where the two regulating edges 46a and 46b of one side piece 40 contact the inward protrusion 45 or the bottom piece 34 of the other side piece 40.

[0048] According to the required rotation range between adjacent side pieces 40, the shapes of the first regulating edge 46a and the second regulating edge 46b are set as appropriate.

[0049] The bottom piece 34 connects the one-side edges of the pair of side pieces 40. The first wire accommodation space 36 is a space surrounded by the bottom piece 34 and the pair of side pieces 40. The first wire accommodation space 36 is open on both sides in the longitudinal direction of the side piece 40. The direction passing through the both openings of the first wire accommodation space 36 is the penetration direction of the first wire accommodation space 36. This penetration direction is along the longitudinal direction of the side piece 40. The first wire 22 can be accommodated in the first wire accommodation space 36 in a penetrating state extending on both sides in the longitudinal direction of the side piece 40. The first wire accommodation space 36 is also open on the side opposite to the bottom piece 34. This opening is the accommodation opening 38 for accommodating the first wire 22. The first wire accommodation space 36 is located on the bottom piece 34 side, that is, the back side, with respect to the accommodation opening 38. The first wire 22 is accommodated in the first wire accommodation space 36 in a penetrating state through the accommodation opening 38.

[0050] On the other-side edges of the pair of side pieces 40, inward protrusions 45 protruding toward the center in the width direction of the pair of side pieces 40 are formed. The inward protrusions 45 are formed at the longitudinal middle portions of the other-side edges of the pair of side pieces 40. There is a gap between the tip ends of the pair of inward protrusions 45. The gap is set to a size that allows the first wire 22 to pass through.

[0051] The above-mentioned inward protruding portion 45 can be in contact with the above-mentioned first regulating edge 46a. The surface of the inward protruding portion 45 on the side opposite to the negative film 34 is formed as a support surface 45f along the longitudinal direction of the side piece 40 and the direction perpendicular to the side piece 40. The lid component 50 is stably supported on the support surface 45f.

[0052] The main body component 32 has locking protrusions 48 as locking parts located on both sides of the accommodating opening 38. Here, a long hole 45g is formed along the longitudinal direction of the side piece 40 in the middle part of the longitudinal direction of the inward protruding portion 45. A locking protrusion 48 as a locking part protrudes through the hole 45g from the other edge of the side piece 40. The locking protrusion 48 has a plate part 48a protruding outward in the width direction of the side piece 40 and a protrusion 48b protruding from the tip of the plate part 48a in the thickness direction of the plate part 48a. The plate part 48a is formed at a distance from the inner peripheral surface of the hole 45g and can be elastically deformed within the hole 45g. The protrusion 48b protrudes toward the outside of the pair of side pieces 40. The tip of the protrusion 48b is formed as a guide surface 48g whose height gradually decreases toward the tip of the plate part 48a.

[0053] The lid component 50 is a component integrally formed by a mold with resin separately from the main body component 32. The lid component 50 has a lid main body part 52 and an additional surrounding part 60.

[0054] The lid main body part 52 includes a plate-shaped part that closes the accommodating opening 38. The lid main body part 52 does not need to close the entire accommodating opening 38, and it is sufficient to close the accommodating opening 38 to prevent the first electric wire 22 from coming off from the accommodating opening 38. In the present embodiment, the lid main body part 52 closes the accommodating opening 38 at the part where the inward protruding portion 45 exists.

[0055] More specifically, the lid main body part 52 includes a rectangular plate-shaped part. The width of the lid main body part 52 is set to be larger than the interval between the pair of side pieces 40. The length of the lid main body part 52 is set to be long enough to cover the inward protruding portion 45. The lid main body part 52 can cover the accommodating opening 38 in a state of being placed on the support surfaces 45f of the pair of inward protruding portions 45.

[0056] The lid body 52 has positioning assistant protrusions 53 extending on the other side edge outward surfaces of the pair of side pieces 40. When the lid body 52 closes the storage opening 38, the pair of positioning assistant protrusions 53 come into contact with the outward surfaces of the pair of side pieces 40, thereby positioning the lid body 52 in the width direction.

[0057] The lid body 52 has a lock protrusion 48. Lock The locking portion has a locking hole 54. In this embodiment, the locking hole 54 is formed in a corner portion from the portion of the lid main body 52 that is placed on the support surface 45f to the positioning auxiliary protrusion 53. An edge 53a of the locking hole 54 formed in the positioning auxiliary protrusion 53 faces the protruding direction of the locking protrusion 48. Therefore, the protrusion 48b of the locking protrusion 48 engages with the edge 53a, thereby locking the lid main body 52 so that it does not come off from the other side edge of the side piece 40.

[0058] The lock hole 54 also extends to a portion of the lid body 52 that is placed on the support surface 45f. The lock protrusion 48 can elastically deform in the thickness direction of the plate 48a by using the portion of the lock hole 54 that extends onto the support surface 45f.

[0059] The pair of locking protrusions 48 are engaged with the pair of locking holes 54 to prevent them from coming off, thereby attaching the cover part 50 to the main body part 32. Note that the locking holes may be formed in the main body part, and the locking protrusions may be formed in the cover part.

[0060] The lid main body 52 has a pair of auxiliary pieces 55 that extend toward the bottom piece 34 inside the tip of the inward protrusion 45. When the lid part 50 is attached to the body part 32, the pair of auxiliary pieces 55 come into contact with the tip of the inward protrusion 45, thereby suppressing rattling of the lid main body 52 relative to the body part 32.

[0061] The additional enclosure portion 60 is a portion that forms a second wire accommodation space 64 for accommodating the second wire 24 in a penetrating state. The second wire accommodation space 64 is a space partitioned by the lid main body portion 52 from the first wire accommodation space 36.

[0062] In the present embodiment, the additional enclosure portion 60 has a pair of base end portions 61 and an enclosure main body portion 62.

[0063] The pair of base end portions 61 are located inside the pair of lock hole portions 54. The pair of base end portions 61 are long plate-shaped along the longitudinal direction of the side piece 40 and protrude to the side opposite to the main body component 32 with respect to the lid main body portion 52.

[0064] The enclosure main body portion 62 connects the tip ends between the pair of base end portions 61 at a position away from the lid main body portion 52. In the present embodiment, the enclosure main body portion 62 is formed in a plate shape that draws an arc shape convex to the side opposite to the bottom piece 34 when viewed along the longitudinal direction of the side piece 40. Therefore, in the present embodiment, the additional enclosure portion 60 forms a U shape in which the pair of base end portions 61 are continuous at both ends of the enclosure main body portion 62 when viewed along the longitudinal direction of the side piece 40.

[0065] Since the pair of base end portions 61 are located inside the pair of lock hole portions 54 and the enclosure main body portion 62 connects the pair of base end portions 61, the entire additional enclosure portion 60 is located inside the pair of lock hole portions 54.

[0066] It should be noted that it is not essential for the enclosure main body portion 62 to form a U shape when viewed along the longitudinal direction of the side piece 40. The enclosure main body portion 62 may be connected to the pair of base end portions 61 at an angle such as a right angle. The enclosure main body portion 62 may be in a flat plate shape or a V-shaped plate shape.

[0067] The space surrounded by the lid main body portion 52, the pair of base end portions 61, and the lid main body portion 52 is a second wire accommodation space 64 for accommodating the second wire 24. The second wire accommodation space 64 is open on both sides along the longitudinal direction of the side piece 40. The penetration direction of the second wire accommodation space 64 is along the longitudinal direction of the side piece 40. The second wire 24 is accommodated in the second wire accommodation space 64 in a penetrating state along the longitudinal direction of the side piece 40. The second wire accommodation space 64 is partitioned from the first wire accommodation space 36 by the lid main body portion 52.

[0068] Therefore, the first wire 22 is accommodated in the first wire accommodation space 36, and separately from this, the second wire 24 is accommodated in the second wire accommodation space 64. It is suppressed that the first wire 22 enters the second wire accommodation space 64 or the second wire 24 enters the first wire accommodation space 36.

[0069] As described above, it is assumed that the second wire 24 is less than the first wire 22. For this reason, when viewed along the longitudinal direction of the first wire 22 and the second wire 24, the second wire accommodation space 64 may be smaller than the first wire accommodation space 36. Thereby, a smaller number of the second wires 24 can be accommodated in a narrower space, and a larger number of The first electric wire 22 can be accommodated in a wider accommodation space.

[0070] As described above, the enclosure main body portion 62, which is the portion of the additional enclosure portion 60 on the side opposite to the main body component 32, is formed in an arc shape that protrudes outward when viewed along the penetration direction of the second wire accommodation space 64. For this reason, the height of the central portion in the width direction of the second wire accommodation space 64 is larger than that on both sides thereof.

[0071] The length of the additional enclosure portion 60 in the penetrating direction of the second wire accommodation space 64 is formed so as to gradually decrease as it moves away from the main body component 32. In the present embodiment, the pair of base end portions 61 are formed so as to gradually become narrower as they move away from the lid main body portion 52. The enclosure main body portion 62 is also formed so that its length gradually shortens as it moves away from the lid main body portion 52. For this reason, when viewing the additional enclosure portion 60 along the width direction of the lid main body portion 52, the additional enclosure portion 60 has a trapezoidal shape that gradually becomes narrower as it moves away from the lid main body portion 52.

[0072] For this reason, when the adjacent wire movable path regulating components 30 are rotated in the direction of approaching the enclosure main body portion 62, it becomes difficult for the adjacent enclosure main body portions 62 to interfere with each other. Thereby, the rotation range of the adjacent wire movable path regulating components 30 can be set large.

[0073] The lid component 50 has a regulated shape surface symmetry with respect to a plane orthogonal to its width direction. That is, the pair of positioning auxiliary protrusions 53 and the pair of lock hole portions 54 in the lid main body portion 52 are formed in a symmetric shape with respect to the left and right along the width direction. The additional enclosure portion 60 is also formed in a symmetric shape with respect to the left and right. Further, the lid component 50 has a regulated shape surface symmetry with respect to a plane orthogonal to the penetrating direction of the second wire accommodation space 64. That is, the pair of positioning auxiliary protrusions 53 and the pair of lock hole portions 54 in the lid main body portion 52 are formed in a symmetric shape with respect to the front and rear directions, which is the penetrating direction of the second wire accommodation space 64. The additional enclosure portion 60 is also formed in a symmetric shape with respect to the front and rear directions.

[0074] For this reason, even if the mounting orientation of the lid component 50 with respect to the main body component 32 is reversed left and right, the combined shape of the main body component 32 and the lid component 50 is the same shape. That is, considering the combination of the pair of lock protrusions 48 and the pair of lock hole portions 54, there are two possible mounting postures of the lid component 50 with respect to the main body component 32. In any posture, the combined shape of the main body component 32 and the lid component 50 is the same shape.

[0075] Here, the regulated shape surface symmetry means having surface symmetry with respect to the shape for restricting the paths of the electric wires 22 and 24. That is, it means having surface symmetry with respect to the functional part related to the function of keeping the lid component 50 in a state of accommodating the first electric wire 22 and the second electric wire 24 and restricting the range within which the movable path regulating component 30 for the electric wire rotates. Therefore, for example, regarding the shape part on the design of the lid component 50 that does not affect the above functions, it does not necessarily have to have the above surface symmetry.

[0076] <Operation of the Path-Regulating Wire Harness> An operation example of the path-regulating wire harness 20 will be described.

[0077] The path-regulating wire harness 20 is disposed so as to span between the vehicle body main body 10 and the sliding door 14. In this state, one end of the movable path regulating components 30 for the electric wires among the plurality of movable path regulating components 30 connected in a row is connected to the vehicle body main body 10. The other end of the movable path regulating components 30 for the electric wires among the plurality of movable path regulating components 30 is connected to the sliding door 14. As a result, the plurality of movable path regulating components 30 for the electric wires move so as to bend along with the opening and closing operation of the sliding door 14. Between adjacent movable path regulating components 30 for the electric wires, they are regulated to rotate around the axis of the pair of connecting protrusions 44. Also, between adjacent movable path regulating components 30 for the electric wires, the rotation range is regulated by the shapes of the first regulating edge 46a and the second regulating edge 46b. For this reason, the plurality of movable path regulating components 30 for the electric wires are path-regulated to bend in a predetermined bending form.

[0078] The first electric wire 22 and the second electric wire 24 can bend while being path-regulated by the plurality of movable path regulating components 30 along with the opening and closing of the sliding door 14. At this time, the first electric wire 22 is path-regulated by the plurality of first electric wire accommodating spaces 36 arranged in a row. The second electric wire 24 is path-regulated by the plurality of second electric wire accommodating spaces 64 arranged in a row adjacent to the first electric wire 22.

[0079] Note that the plurality of movable path restricting components 30 for electric wires connected in a row may be covered by an exterior member 70 formed in a cylindrical shape with rubber or the like (see FIGS. 1 and 5). The exterior member may be a member also called a rubber boot, for example.

[0080] If the first wire accommodation space 36 and the second wire accommodation space 64 are spaces that are continuous with each other, then the first wire 22 moves toward the second wire accommodation space 64 side, and the second wire 24 On the side of the first electric wire accommodation space 36 may move. In that case, the degree of freedom of the positions of the first wire 22 and the second wire 24 within the movable path restricting component 30 for electric wires increases. For this reason, when the path restricting wire harness 20 is in a bent state, an unstable state occurs in which the first wire 22 is located on the inner peripheral side or the second wire 24 is located on the inner peripheral side. Then, for each of the first wire 22 and the second wire 24, the change in the path length corresponding to the change in the path of the path restricting wire harness 20 may increase.

[0081] In the present embodiment, the first wire 22 is path-restricted by the first wire accommodation space 36, and the second wire 24 is path-restricted by the second wire accommodation space 64 adjacent to the first wire 22. Therefore, the first wire 22 and the second wire 24 are path-restricted within a limited range as compared with the case where the first wire accommodation space 36 and the second wire accommodation space 64 are continuous with each other. For this reason, it is possible to reduce the change in the path lengths of the first wire 22 and the second wire 24 due to the change in the path of the path restricting wire harness 20.

[0082] For this reason, it is easy to predict the required lengths of the first wire 22 and the second wire 24. Also, it is easy to predict the bending directions of the first wire 22 and the second wire 24 within the path restricting wire harness 20. For this reason, it becomes easy to predict the bending performance of the first wire 22 and the second wire 24. Note that the bending performance can be evaluated, for example, by the number of bending times until the first wire 22 and the second wire 24 reach disconnection when repeated bending is performed under conditions path-restricted by the movable path restricting component 30 for electric wires.

[0083] <Usage Example> The above-described route control wire harness 20 can be used, for example, in the following scenarios.

[0084] For example, in the basic design, assume that a route control wire harness including at least one first electric wire 22 and not including a second electric wire 24 is designed. The basic design is, for example, a design related to the initial model of an automobile. In the basic design, the electrical components incorporated in the sliding door 14 are set. As the route control wire harness corresponding to the basic design, a route design is made to control the bending of the first electric wire 22 connected to the electrical components incorporated in the sliding door 14. As this route control wire harness, a movable route control component for an electric wire in which the additional enclosure portion 60 in the above-described route control wire harness 20 is omitted is adopted.

[0085] After that, assume that an additional design is made to add electrical components to the sliding door 14. In this case, it becomes necessary to additionally control the route of the second electric wire 24 connected to the additional electrical components. The first electric wire accommodation space 36 is designed to control the route of the first electric wire 22 in the basic design. Therefore, there may be no remaining space for accommodating the second electric wire 24 in the first electric wire accommodation space 36. Also, if the second electric wire 24 is added to the first electric wire accommodation space 36, the behavior of the first electric wire 22 in the first electric wire accommodation space 36 may change, and the bending performance of the first electric wire 22 may change.

[0086] Therefore, as described above, the lid component 50 with the additional enclosure portion 60 is set. Instead of the lid component adopted in the basic design, the lid component 50 having the additional enclosure portion 60 is attached to the main body component 32. The main body component 32 is the same as the main body component 32 in the basic design.

[0087] In this case, for the first electric wire 22, the routing is regulated in the same way as in the basic design. Therefore, for the second electric wire 24, it is only necessary to predict the bending performance. Since the second electric wire 24 is routed within the second electric wire accommodation space 64 partitioned from the first electric wire accommodation space 36, the bending behavior of the second electric wire 24 is stable, and the variation in the path length due to bending is small. Therefore, it is easy to predict the bending performance due to the addition of the second electric wire 24.

[0088] <Effects, etc.> According to the movable routing regulation component 30 for electric wires and the routing regulation wire harness 20 configured as described above, even if the second electric wire 24 is added to the routing regulation wire harness based on the basic design, the first electric wire 22 is routed within the first electric wire accommodation space 36 based on the basic design. Therefore, the addition of the second electric wire 24 hardly affects the movement of the first electric wire 22. Also, the second electric wire 24 is routed within the second electric wire accommodation space 64 partitioned from the first electric wire accommodation space 36. Since the first electric wire 22 is routed within the first electric wire accommodation space 36 and the second electric wire 24 is routed within the second electric wire accommodation space 64, the ranges of the first electric wire 22 and the second electric wire 24 during routing changes are limited. Therefore, the change in the path length according to the routing changes of the first electric wire 22 and the second electric wire 24 is reduced. As a result, the variation in the loads acting on the first electric wire 22 and the second electric wire 24 when the routing of the first electric wire 22 and the second electric wire 24 changes is reduced. Consequently, it becomes easy to predict the bending performance of the first electric wire 22 and the second electric wire 24.

[0089] Also, since the main body component 32 can be diverted from that in the basic design, it is not necessary to start a new mold. For the lid main body 52 as well, it is only necessary to add the surrounding portion 60 to the shape in the basic design, so the design is easy.

[0090] Also, if the second electric wire 24 is less than the first electric wire 22, the second electric wire 24 can be easily added. Also, since the added second electric wire 24 is accommodated in the second electric wire accommodation space 64 smaller than the first electric wire accommodation space 36, the movable range during routing regulation of the second electric wire 24 is limited. Thereby, it becomes easier to predict the bending performance of the second electric wire 24.

[0091] In addition, since the additional surrounding portion 60 is provided inside the lock hole portion 54, the lock hole portion 54 can be easily formed by die casting without the additional surrounding portion 60 getting in the way.

[0092] In addition, since the lid component 50 has symmetry in the regulating shape surfaces in the left - right direction and the front - rear direction, the lid component 50 can be attached to the main body component 32 without worrying about the orientation.

[0093] In addition, the length of the additional surrounding portion 60 in the front - rear direction is set to gradually decrease as it moves away from the main body component 32. For this reason, when the movable path regulating component 30 for electric wires rotates with respect to the adjacent movable path regulating component 30 for electric wires, the additional surrounding portion 60 is less likely to interfere with the adjacent additional surrounding portion 60. Therefore, it is easy to set a large rotation range between adjacent movable path regulating components 30 for electric wires.

[0094] In addition, the portion of the additional surrounding portion 60 on the side opposite to the main body component 32 is formed in an arc shape. For this reason, when covering the outside of a plurality of movable path regulating components 30 for electric wires arranged in a row with the exterior member 70, the additional surrounding portion 60 is less likely to get caught on the exterior member 70, and it is easy to cover the exterior member 70 on the movable path regulating components 30 for electric wires. Also, The second electric wire 24 it is easy to maintain at the center in the width direction of the additional surrounding portion 60.

[0095] Note that the respective configurations described in the above - mentioned embodiments and each modification can be appropriately combined as long as they do not conflict with each other.
