[0003] [Patent Document 1] Japanese Patent Publication No. 2020-124073 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the outer casing member through which the electric wire is inserted is formed, for example, in a cylindrical shape with a larger diameter than the electric wire, excess parts such as wrinkles and slack may occur around the circumference of the outer casing member, and the presence of these excess parts may cause variations in the assembly positions of each component.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] [Embodiment] Fig. 1 is a perspective view schematically showing a sunroof of an automobile in which a wire harness according to an embodiment is arranged. Fig. 2 is an exploded perspective view of the wire harness according to an embodiment. Fig. 3 is a plan view of a protector body of the wire harness. Fig. 4 is a sectional perspective view of the protector body shown in Fig. 3. Fig. 5 is an assembled sectional view of the wire harness.

[0011] As shown in FIG. 1 , the wire harness WH of this embodiment electrically connects, for example, the vehicle body and a sunroof (glass window) 100 of a vehicle, and is used for power supply and signal communication. The sunroof 100 is a mobile object mounted on the roof of the vehicle body and electrically slides relative to the vehicle body. The sunroof 100 has electrical devices 100a, such as switches and motors, that are operated by power supplied from the vehicle battery. As shown in FIGS. 1 and 2 , the wire harness WH has electric wires 1, a leaf spring member 2, an exterior member 3, a protector (holding member) 4, and a connector 5. In this embodiment, the protector 4 of the wire harness WH is attached to the sunroof 100 by, for example, engaging grooves 4c formed on both sides of the protector 4 with claws of a bracket (not shown). The connector 5 provided at the end of the electric wire 1 leading out from the protector 4 is coupled to a mating connector and connected to the electrical device 100a.

[0012] In the following description, for convenience, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "width direction X," the second direction will be referred to as the "axial direction Y," and the third direction will be referred to as the "height direction Z." The width direction X, the axial direction Y, and the height direction Z are typically perpendicular to (intersect with) one another. Here, the axial direction Y corresponds to the sliding movement direction of the sunroof 100 described above and corresponds to the axial direction of the protector 4 attached to the sunroof 100. The width direction X and the height direction Z correspond to the width direction and height direction of the protector 4 attached to the sunroof 100. The height direction Z also includes a state in which the protector 4 is turned upside down.

[0013] The electric wire 1 is a flexible conductive member. The electric wire 1 has a conductor portion (core wire) made of a plurality of conductive metal wires covered with an insulating coating portion. In this embodiment, as shown in FIG. 2, the wire harness WH is configured to include two electric wires 1.

[0014] The leaf spring member 2 is a band-shaped elastic member that extends along the electric wire 1 and regulates the path of the electric wire 1.

[0015] The exterior member 3 is flexible. In this embodiment, the exterior member 3 is formed by weaving insulating fibers into a cylindrical (tube-like) shape, and has, for example, an oval cross-sectional shape. As shown in FIG. 2 , the electric wire 1 and the leaf spring member 2 are inserted into the exterior member 3. The electric wire 1 and the leaf spring member 2 are inserted into the exterior member 3 together in a state where they are overlapped in the height direction Z. Ends of the electric wire 1 and the leaf spring member 2 are led out from an end 3a of the exterior member 3.

[0016] The end portions 21 of the leaf spring member 2 have a convex shape that protrudes in the width direction X that intersects with the axial direction Y. Specifically, the leaf spring member 2 has cutout portions 22 that are formed by partially cutting out both ends of the leaf spring member 2 in the width direction, and these cutout portions 22 cause the end portions 21 of the leaf spring member 2 to have a convex shape that protrudes relatively in the width direction X. Note that the end portions 21 of the leaf spring member 2 may have a convex shape that protrudes relatively in the width direction X, and both ends of the width direction may also have a convex shape that protrudes in the width direction.

[0017] As shown in Fig. 1, the protector 4 is made of insulating synthetic resin and has a hollow, generally rectangular cylindrical shape. The protector 4 introduces the electric wire 1, the leaf spring member 2, and the exterior member 3 through an inlet 4a provided at one axial end thereof, and leads the electric wire 1 out through an outlet 4b provided at the other axial end thereof. In this embodiment, as shown in Fig. 2, the protector 4 routes the electric wire 1, the leaf spring member 2, and the exterior member 3, and also integrally holds the end 3a of the exterior member 3 and the portions of the electric wire 1 and the leaf spring member 2 that lead out from the end 3a of the exterior member 3 inside thereof.

[0018] The protector 4 includes a protector main body (main body) 10 and a lid portion 30. The protector main body 10 has a first side surface 11, a second side surface 12, and a third side surface 13. In the example shown in FIG. 2, the second side surface 12 and the third side surface 13 of the protector main body 10 face each other, and the surface (lower surface) facing the first side surface 11, which serves as the upper surface, is open, forming a U-shape. The protector main body 10 has a wiring space 14 formed by the first side surface 11, the second side surface 12, and the third side surface 13. The wiring space 14 routes the electric wire 1, the leaf spring member 2, and the exterior member 3 along the axial direction Y. In this case, the electric wire 1 and the leaf spring member 2 are inserted into the exterior member 3 in a state where they are overlapped with each other so that the leaf spring member 2 faces the protector main body 10. Therefore, the electric wire 1 is located on the lid portion 30 side of the exterior member 3.

[0019] The lid portion 30 is formed in a plate shape, and in the example of FIG. 2 , it is attached to the surface (underside) facing the first side surface portion 11 of the protector body 10 to close the above-mentioned wiring space 14. In this embodiment, the lid portion 30 is attached to the protector body 10 by being fitted to the second side surface portion 12 and the third side surface portion 13 of the protector body 10. The lid portion 30 includes a base portion 31, a first fitting base portion 32, a second fitting base portion 33, a plurality of first protrusions 34 and second protrusions 35, and a pair of fitting pieces 36. When the protector body 10 and the lid portion 30 are fitted together, the base portion 31 closes the wiring space 14 and forms the side surface of the protector 4.

[0020] The first fitting base 32 and the second fitting base 33 are arranged side by side in the axial direction Y on the upper surface 31a of the base portion 31 (the surface facing the wiring space 14 of the protector body 10). The first fitting base 32 is formed on the inlet 4a (FIG. 1) side in the axial direction Y of the protector 4, and the second fitting base 33 is formed on the outlet 4b side. The first fitting base 32 and the second fitting base 33 have outer surfaces that are the same shape as the inner surfaces of the second side surface 12 and the third side surface 13, and are fitted between the second side surface 12 and the third side surface 13. In this embodiment, when the upper surface 31a of the base portion 31 is used as a reference, the upper surface 32a of the first insertion base portion 32 (the surface facing the wiring space portion 14 of the protector main body 10) is formed at a higher height position in the height direction Z than the upper surface 33a of the second insertion base portion 33 (the surface facing the wiring space portion 14 of the protector main body 10).

[0021] The first protrusions 34 and the second protrusions 35 are erected from the upper surface of the first fitting base portion 32 (the surface facing the wiring space 14 of the protector body 10) so as to protrude toward the protector body 10. As shown in FIG. 5 , the first protrusions 34 and the second protrusions 35 engage with the exterior member 3 routed in the wiring space 14, thereby fixing the exterior member 3 within the protector 4. Specifically, since the exterior member 3 is formed by knitting resin fibers, the tips of the first protrusions 34 and the second protrusions 35 pierce (penetrate) the gaps between the stitches of the exterior member 3, thereby locking the exterior member 3. Note that, although the exterior member 3 is formed by knitting resin fibers in this embodiment, it may be formed of any flexible material (such as synthetic rubber) as long as it can be locked onto the tips of the first protrusions 34 and the second protrusions 35, or the tips of the first protrusions 34 and the second protrusions 35 may be locked into grooves in a corrugated tube.

[0022] In this embodiment, the first protrusion 34 is formed on the introduction port 4a side in the axial direction Y of the protector 4, and the second protrusion 35 is formed closer to the center in the axial direction Y than the first protrusion 34. The first protrusion 34 is formed on the outer side in the width direction X of the protector 4, and the second protrusion 35 is formed closer to the center (inner side) in the width direction X than the first protrusion 34. The height positions of the tips of the multiple first protrusions 34 and second protrusions 35 in the height direction Z of the protector 4 differ depending on the formation positions of each protrusion. In the example of FIG. 2 , the height positions of the tips of the first protrusion 34 and the second protrusion 35 in the height direction Z are different. For example, when the leaf spring member 2 routed in the routing space portion 14 is used as a reference, the height position of the tip of the first protrusion 34 is lower than that of the second protrusion 35. In this way, the height positions of the tips of the multiple first protrusions 34 and second protrusions 35 in the height direction Z of the protector 4 differ depending on the formation position of each protrusion, so that even if excess portions such as wrinkles or slack occur in the circumferential direction of the exterior member 3, the components can be properly assembled. Furthermore, even if the exterior member 3 is pulled, the first protrusions 34 and second protrusions 35 having different heights distribute stress, preventing excessive load from being applied to these protrusions or the exterior member 3.

[0023] The pair of fitting pieces 36 are arranged side by side in the width direction X with the first fitting base portion 32 in between, and stand on the upper surface 31a of the base portion 31. The pair of fitting pieces 36 are also formed on the second fitting base portion 33 side of the first fitting base portion 32 in the axial direction Y. These fitting pieces 36 are fitted into recesses 15 formed on the inner surfaces of the second side surface portion 12 and the third side surface portion 13 of the protector body 10.

[0024] 3 and 4, the protector body 10 has a recess 15 and a protrusion 16 formed on the inner surface exposed to the wiring space 14. The protrusion 16 is formed on the outlet 4b (FIG. 1) side in the axial direction Y of the protector 4, and protrudes toward the lid 30. As shown in FIG. 5, the protrusion 16 is formed opposite to the upper surface 33a of the second fitting base 33 of the lid 30, and clamps a part of the electric wire 1 that is led out from the end 3a of the exterior member 3 and routed in the wiring space 14 between the protrusion 16 and the upper surface 33a of the second fitting base 33.

[0025] In this embodiment, the electric wire 1 is disposed closer to the lid 30 than the leaf spring member 2, and the protrusion 16 protrudes from the protector body 10 toward the lid 30. Therefore, when the electric wire 1 is sandwiched between the protrusion 16 and the upper surface 33a of the second fitting base 33, the electric wire 1 can be easily separated from the leaf spring member 2. Therefore, for example, it is possible to prevent the electric wire 1 from coming into contact with the end of the leaf spring member 2, and to make the electric wire 1 less likely to be damaged. Furthermore, as shown in FIGS. 4 and 5 , the surface of the protrusion 16 facing the electric wire 1 in the axial cross section is curved. Therefore, when the electric wire 1 is sandwiched between the protrusion 16 and the upper surface 33a of the second fitting base 33, it is possible to prevent the electric wire 1 from being damaged by the sandwiching.

[0026] As shown in FIG. 5 , the recess 15 is formed between the protruding portion 16 and the first protrusion 34 and the second protrusion 35 provided on the lid portion 30 in the axial direction Y. The recess 15 is formed on each inner surface of the second side surface portion 12 and the third side surface portion 13, and engages with the convex end 21 of the leaf spring member 2 to position the end 21 of the leaf spring member 2 in the axial direction Y. When assembling the wire harness WH, the electric wire 1 and the leaf spring member 2 inserted through the exterior member 3 are placed in the wiring space 14, and the convex end 21 of the leaf spring member 2 is engaged with the recess 15 of the protector body 10. This makes it easy to position the end 21 of the leaf spring member 2 in the axial direction Y, and the electric wire 1, the leaf spring member 2, and the exterior member 3 can be assembled to the protector body 10. Furthermore, a pair of fitting pieces 36 provided on the lid portion 30 are fitted into the recess 15. As a result, by assembling the cover portion 30 to the protector body 10, the end portion 21 of the leaf spring member 2 is prevented from coming off the recessed portion 15, and the leaf spring member 2 can be fixed to the protector 4.

[0027] Incidentally, the exterior member 3 through which the electric wires 1 and the leaf spring members 2 are inserted is formed, for example, in a cylindrical shape with a larger diameter than the electric wires 1 and the leaf spring members 2. Therefore, excess portions such as wrinkles and slack are generated in the circumferential direction of the exterior member 3, and the presence of these excess portions may cause variations in the assembly positions of the components (the electric wires 1, the leaf spring members 2, and the exterior member 3) within the protector 4. Furthermore, the wire harness WH according to this embodiment connects, for example, the vehicle body side to the sunroof 100, and the position and shape of the wire harness WH fluctuate following the sliding movement of the sunroof 100. For this reason, it is desirable to assemble the components of the wire harness WH within the protector 4 in an appropriate positional relationship in order to ensure stable operation.

[0028] Next, a structure for assembling each component (electric wire 1, leaf spring member 2, and exterior member 3) in the protector 4 in the proper positional relationship will be described. Fig. 6 is a schematic diagram showing the positional relationship of each component assembled to the protector body. In Fig. 6, the cover is not shown and the protector is shown upside down compared to Fig. 2.

[0029] As shown in Figures 3, 4, and 6, the protector main body 10 is configured to include a defining portion 17 and an accommodating recess 18 formed on the inner surface exposed to the wiring space portion 14. The defining portion 17 and the accommodating recess 18 are provided on the opposite side of the first protrusion 34 and the second protrusion 35 in the height direction Z. As shown in Figure 6, the defining portions 17 are formed on both sides of the inner surface of the first side surface portion 11 in the width direction X, and support both ends in the width direction X of the leaf spring member 2 routed in the wiring space portion 14 via the exterior member 3. Furthermore, the defining portions 17 define the height position of the leaf spring member 2 within the protector main body 10 (protector 4) in the height direction Z.

[0030] In this embodiment, as shown in Fig. 1, the leaf spring member 2 is curved in a substantially U-shape outside the protector 4 together with the electric wire 1 and the exterior member 3. That is, the leaf spring member 2 is folded back in the axial direction Y outside the protector 4 and passes below the protector 4 in the height direction Z. Therefore, a biasing force generated by the bending acts on the end of the leaf spring member 2, and as shown in Fig. 6, this biasing force F constantly presses the leaf spring member 2 inside the protector main body 10 (protector 4) against the defining portion 17. This allows the height position of the leaf spring member 2 inside the protector 4 to be aligned with the position (reference position) of the defining portion 17.

[0031] As shown in FIG. 6 , the accommodating recess 18 is a recess that is located between a pair of defining portions 17 and is formed farther away from the leaf spring member 2 in the height direction Z than the defining portions 17. As described above, the accommodating recess 18 accommodates excess portions 3b, such as wrinkles or slack, that occur in the circumferential direction of the exterior member 3. In a configuration without an accommodating recess, the excess portions 3b of the exterior member 3 are interposed between the leaf spring member 2 and the defining portions 17, making it impossible to position the leaf spring member 2 at the reference position, resulting in variations in the assembly positions of the various components. Furthermore, the excess portions 3b of the exterior member 3 may prevent the cover 30 from being properly attached.

[0032] In this embodiment, the accommodating recess 18 is provided, which is located between the pair of defining portions 17 and is formed further away from the leaf spring member 2 in the height direction Z than the defining portions 17. Therefore, if an excess portion 3b such as wrinkles or slack occurs in the circumferential direction of the exterior member 3, for example, this excess portion 3b is accommodated in the accommodating recess 18. Therefore, regardless of the excess portion 3b, the height position of the leaf spring member 2 can be aligned to the reference position, the cover portion 30 can be properly attached, and each member can be assembled in a proper positional relationship.

[0033] Next, modified examples of the accommodating recess will be described. Figures 7 and 8 are schematic diagrams showing the positional relationship of each component assembled to a protector main body having an accommodating recess according to a modified example. In Figures 7 and 8, the lid is also omitted from the illustration, and the accommodating recess is shown upside down compared to Figure 2. Figure 6 describes an accommodating recess formed in a plane substantially parallel to an imaginary plane connecting the pair of defining portions 17, 17, but the shape and depth of the accommodating recess can also be changed as appropriate.

[0034] For example, as shown in FIG. 7, the protector main body 10A (protector 4A) may have an accommodating recess 18A having an arc-shaped bottom surface (top surface) between a pair of defining portions 17, 17. Also, as shown in FIG. 8, the protector main body 10B (protector 4B) may have an accommodating recess 18B having a trapezoidal bottom surface (top surface) between a pair of defining portions 17, 17. The shape and depth of these accommodating recesses 18A, 18B are selected depending on the size of the surplus portion 3b expected to be generated in the circumferential direction of the exterior member 3. Even in such a modified example, regardless of the surplus portion 3b, the height position of the leaf spring member 2 within the protector 4 can be aligned to a reference position, the cover portion 30 can be properly attached, and the various components can be assembled in the proper positional relationship.

[0035] As described above, the wire harness WH according to the present embodiment includes the flexible electric wires 1, the leaf spring members 2 that extend along the electric wires 1 and regulate the path of the electric wires 1 and have elasticity, the flexible exterior member 3 through which the electric wires 1 and the leaf spring members 2 are inserted, and the protector 4 that integrally holds the end 3 a of the exterior member 3 and the portions of the electric wires 1 and the leaf spring members 2 that are led out from the end 3 a of the exterior member 3, and the protector 4 is configured to hold the electric wires 1, the leaf spring members 2, and the exterior member 3 in an axial direction Y. The protector 4 includes a protector body 10 having a wiring space 14 in which the leaf spring member 2 is arranged, and a lid portion 30 attached to the protector body 10 and closing the wiring space 14. The wiring space 14 is provided with a pair of regulating portions 17 that support both widthwise ends of the routed leaf spring member 2 via an exterior member 3 and regulate the height position of the leaf spring member 2 within the protector 4 in a height direction Z that intersects with the axial direction Y, and an accommodating recess 18 that is located between the pair of regulating portions 17, 17 and accommodates a circumferential excess portion 3b of the exterior member 3.

[0036] According to this configuration, even if excess portions 3b such as wrinkles or slack occur in the circumferential direction of the exterior member 3, these excess portions 3b are accommodated in the accommodating recess 18, so that regardless of the excess portions 3b, the height position of the leaf spring member 2 can be positioned at the reference position which is the determining portion 17, and each member can be assembled in an appropriate positional relationship.

[0037] Furthermore, in the wire harness WH according to this embodiment, the leaf spring member 2 is curved in a substantially U-shape outside the protector 4, and is pressed against the defining portion 17 via the exterior member 3 by the biasing force of the leaf spring member 2, and is supported by the defining portion 17. According to this configuration, the biasing force generated by the bending of the leaf spring member 2 acts on the end of the leaf spring member 2, and the leaf spring member 2 in the protector 4 is constantly pressed against the defining portion 17 by this biasing force. Therefore, the height position of the leaf spring member 2 in the protector 4 can be aligned with the position (reference position) of the defining portion 17.

[0038] Moreover, in the wire harness WH according to this embodiment, the protector 4 has a plurality of first protrusions 34 and second protrusions 35 that protrude from the cover portion 30 toward the protector body 10 and lock the exterior member 3 on the opposite side of the defining portion 17 in the height direction Z. According to this configuration, the exterior member 3, whose movement in the height direction Z is restricted by the defining portion 17, can be locked by the first protrusions 34 and the second protrusions 35.

[0039] In the wire harness WH according to the present embodiment, the exterior member 3 is formed by tubularly weaving insulating fibers. With this configuration, the tips of the first protrusions 34 and the second protrusions 35 penetrate (penetrate) the gaps between the stitches of the exterior member 3, thereby locking the exterior member 3.

[0040] The wire harness WH according to the embodiment of the present invention described above is not limited to the above embodiment, and various modifications are possible within the scope of the claims. For example, in the present embodiment, the protrusion 16 that clamps a portion of the electric wire 1 is provided on the protector body 10, but this is not limited thereto, and the protrusion may protrude from the lid portion 30 toward the protector body 10. Furthermore, although the lid portion 30 is provided with a plurality of first protrusions 34 and second protrusions 35 that engage the exterior member 3, the first protrusions 34 and second protrusions 35 may be provided from the protector body 10 toward the lid portion 30.

[0041] In addition, in the present embodiment, the exterior member 3 has been described as being formed by weaving insulating fibers into a cylindrical shape, but this is not limiting and, for example, a flexible rubber-based material may be used as long as it can be engaged with the first protrusions 34 and the second protrusions 35. Also, the exterior member 3 may be configured to have a plurality of grooves that engage with the tips of the protrusions, like a corrugated tube.

[0042] In this embodiment, the height position of the tip of the first protrusion 34 and the second protrusion 35 in the height direction Z is based on the leaf spring member 2, but this is not limited to this and, for example, the top surface 32a of the first fitting base portion 32 of the lid portion 30 may be based on the height position. In this case, the tip of the first protrusion 34 is higher in height position than the second protrusion 35.

[0043] Furthermore, in the present embodiment, a structure has been described in which the biasing force of the leaf spring member 2 is used to press the leaf spring member 2 against the defining portion 17 via the exterior member 3, but the present invention is not limited to this, and for example, a structure may be adopted in which a portion of the first protrusion 34 and the second protrusion 35 are extended until their tips reach the leaf spring member 2, and the first protrusion 34 and the second protrusion 35 press the leaf spring member 2 against the defining portion 17 via the exterior member 3. Furthermore, for example, a structure may be adopted in which the leaf spring member 2 is pressed against the defining portion 17 via the exterior member 3 by fastening the exterior member 3, through which the electric wire 1 and the leaf spring member 2 are inserted, and the protector body with a band.

[0044] Furthermore, in this embodiment, the sunroof 100 has been described as a moving body to which the wire harness WH is provided, but it goes without saying that it may also be provided in, for example, a sliding door. [Explanation of symbols]
