Description

[Technical field]

[0001] The present invention relates to a harness routing structure and a position restricting body capable of preventing water from entering a connector attached to a wire harness. [Background technology]

[0002] Generally, a connector for connecting the wire harness to the electrical equipment is attached to the end of a wire harness that connects various electrical equipment mounted on a vehicle or the like. In recent years, with the increase in electrical equipment, connectors are fixed in various locations. For this reason, depending on the location of the connectors, liquid may get onto the wire harness due to water exposure or condensation. The liquid that gets onto the wire harness may flow along the wire harness toward the tip and may seep into the connector connected to the tip of the wire harness.

[0003] To address this problem, for example, Patent Document 1 discloses a wiring structure for a wire harness in which a wire harness bent back into a U-shape is fixed at a predetermined location so that a connector is disposed above a portion of the wire harness. This is said to prevent liquid that has flowed down the wire harness from flowing above the U-shaped bent portion, thereby preventing liquid from entering the connector.

[0004] However, in such a wire harness routing structure, the portion of the wire harness above a specified point may collapse toward the connector, and liquid that runs down the wire harness may drip near the connection portion of the wire harness with the connector or onto the connector. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2022-24901 Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a harness routing structure and a position regulating body that can prevent liquid from dripping down the wire harness and soaking a connector. [Means for solving the problem]

[0007] The present invention is a harness arrangement structure for wiring a wire harness having a connector attached to its tip, wherein the wire harness is formed with a bent portion that extends downward from a predetermined location and bends back at its tip end upward so as to position the connector below the predetermined location, and the portion of the wire harness that is arranged in the vertical direction from the base end side of the bent portion is a downward portion, and the portion of the wire harness that is arranged from the base end side of the bent portion is an upward portion, and a position regulating body is provided for regulating the relative positions of the downward portion and the upward portion, and the position regulating body is provided with a separation regulating portion that regulates the downward portion and the upward portion so as to separate them horizontally, and a tilt regulating portion that regulates the portion of the downward portion above the connector from tilting close to the connector.

[0008] The present invention is also characterized in that the wire harness is provided with a bent portion that extends downward from a predetermined location and bends its tip side upward so that a connector attached to the tip is positioned below the predetermined location, and the wire harness is provided with a downward portion that is arranged in the up-down direction on the base end side of the bent portion, and an upward portion on the tip side of the bent portion, the downward portion being provided with a separation control portion that controls the horizontal separation between the downward portion and the upward portion, and a tilt control portion that controls the portion of the downward portion above the connector from tilting close to the connector, and the position control body controls the relative positions of the downward portion and the upward portion.

[0009] The wire harness includes not only a bundle of insulated electric wires formed by bundling a plurality of insulated electric wires, or a single insulated electric wire, but also a communication cable such as an optical fiber cable for transmitting information, or a bundle of communication cables, and further includes a bundle of insulated electric wires and communication cables.

[0010] The specified location is a base end portion of the wire harness that is routed downward, and includes, for example, a base end portion of the wire harness that branches off from a main line formed by bundling a plurality of insulated electric wires, or a base end portion of the wire harness that is led downward from an electrical junction box.

[0011] According to the present invention, it is possible to prevent liquid running along the wire harness from unintentionally dripping onto the connector and causing the connector to become wet. In detail, the position of the upward and downward portions can be restricted by the position restricting body having the separation restricting portion and the fall restricting portion, so that the downward portion can be restricted from falling over so as to approach the connector above the connector with the downward portion and the upward portion of the bent wire harness being spaced apart from each other by a predetermined distance in the horizontal direction. This prevents the downward portion from covering the connector above, and prevents liquid running down the wire harness from dripping onto the connector or the vicinity of the connector and the connection portion of the wire harness. Therefore, it is possible to prevent liquid running down the downward portion from unintentionally dripping onto the connector and getting the connector wet.

[0012] As an aspect of the present invention, the separation control portion may be provided below the connector between the downward portion and the upward portion, and the tilt control portion may extend upward from the separation control portion along the downward portion.

[0013] According to this invention, the collapse prevention portion extending upward from the separation prevention portion can support the downward portion over a predetermined range in the vertical direction, thereby more reliably preventing the portion of the downward portion above the separation prevention portion from collapsing closer to the connector.

[0014] As a further aspect of the present invention, a restricting support portion may be provided that supports the falling-down restricting portion, and the restricting support portion may connect the separation restricting portion and the falling-down restricting portion. According to this invention, since the tilt prevention portion can be supported by the prevention support portion connected to the separation prevention portion, the downward portion can be more reliably prevented from tilting toward the connector.

[0015] In another aspect of the present invention, the regulating support portion is inclined so as to move away from the collapse regulating portion as it moves from the upper side to the lower side, and the lower end of the regulating support portion may be positioned below the connector.

[0016] According to this invention, the restricting and supporting portion, the separation restricting portion, and the collapse restricting portion are connected in a substantially triangular shape when viewed from a direction perpendicular to the horizontal direction and the up-down direction, so that the restricting and supporting portion can more firmly support the collapse restricting portion and more reliably restrict the downward portion from collapsing toward the connector.

[0017] In addition, since the lower end of the restricting support part is disposed below the connector, even if liquid that has run down the downward portion flows from the tilting restricting part to the restricting support part, the liquid can be guided below the connector, thereby more reliably preventing the connector from becoming wet.

[0018] As a further aspect of the present invention, the position restricting body may be provided with a protruding portion that protrudes upward between a lower end of the restricting support portion and the connector. According to this invention, the protrusion can prevent liquid that has flowed down the restricting support portion from flowing toward the connector, so that the connector can be reliably prevented from becoming wet.

[0019] As a further aspect of the present invention, a fixing means for fixing the position regulating body to the wire harness may be provided. The fixing means may be any means capable of fixing the position regulating body to the wire harness, and may include a tape, a cable tie, a band clamp, or the like.

[0020] According to the present invention, the position regulating body can be fixed to the wire harness via the fixing means, so that the position regulating body can be prevented from being unintentionally detached from the wire harness. Therefore, the downward portion of the wire harness can be kept prevented from falling toward the connector, and the connector can be reliably prevented from being wet.

[0021] As a further aspect of the present invention, the position restriction body may be provided with a fastening means restriction portion that restricts the position of the fastening means. According to this invention, since the position of the fixing means with respect to the position restriction body can be restricted, the fixing means can be held at a desired position on the position restriction body.

[0022] As a further aspect of the present invention, the position restricting body may be provided with a harness holding portion for holding the wire harness. According to the present invention, it is possible to prevent the position restriction body from unintentionally falling off the wire harness.

[0023] Furthermore, if the position regulating body and the wire harness are fixed by a fixing means, the position regulating body can be disposed at a desired position on the wire harness and the fixing means can be attached thereto, which makes it easy to fix the position regulating body to the wire harness.

[0024] As a further aspect of the present invention, the position regulating body may be formed by folding a resin sheet. The resin sheet is not particularly limited as long as it can be folded, and includes both thermoplastic resin sheets and thermosetting resin sheets. In addition, the resin sheet material is preferably a synthetic resin foam sheet material composed of a synthetic resin foam molded into a foamed or porous shape.

[0025] According to the present invention, since the resin sheet material can be easily processed, the position restricting member corresponding to the shape of the wire harness can be easily formed, thereby improving the productivity of the harness routing structure. Effect of the Invention

[0026] According to the present invention, it is possible to provide a harness routing structure and a position regulating body that can prevent liquid running down the wire harness from dripping onto the connector and becoming wet. [Brief description of the drawings]

[0028] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. Fig. 1 shows a schematic front view of the harness routing structure 1 as seen from one side in the depth direction D, Fig. 2 shows an explanatory diagram of the position regulating body 20, and Fig. 3 shows an explanatory diagram of the regulating body type 50.

[0029] 2 to 5 will be described in detail. Fig. 2(a) shows a front view of the position regulating body 20, and Fig. 2(b) shows a plan view of the position regulating body 20. Fig. 3(a) shows a plan view of the sheet material 40, and Fig. 3(b) shows a plan view of the regulating body mold 50 punched out from the sheet material 40. Fig. 4(a) shows a schematic perspective view of the regulating body mold 50 in the process of assembling the position regulating body 20, and Fig. 4(b) shows a schematic perspective view of the position regulating body 20 assembled by folding the regulating body mold 50. Fig. 5(a) shows a schematic front view of the harness routing structure 1, and Fig. 5(b) shows a cross-sectional view taken along the line AA in Fig. 5(a).

[0030] The dashed lines shown in Fig. 3(b) and Fig. 4(a) indicate imaginary mountain fold lines along which the regulating body mold 50 punched out from the sheet material 40 is mountain-folded or imaginary valley fold lines along which the regulating body mold 50 is valley-folded. In Fig. 5(b), the electrical equipment 30 is not shown. In Fig. 5(b) and Fig. 6, the tape T that wraps the branch wire 12 and the position regulating body 20 is not shown.

[0031] Here, in FIG. 1, the up-down direction in the figure is the height direction H, and the direction perpendicular to the height direction H and along the trunk line 11 is the wiring direction L. The direction perpendicular to the height direction H and the wiring direction L is the depth direction D. In FIG. 1, the upper side along the up-down direction is the upper side Hu, and the lower side is the lower side Hd. Similarly, the left side along the wiring direction L is the rear side La, and the right side is the front side Lb. The directions defined in FIG. 1 are the same in FIG. 2 and FIG. 4 to FIG. 6.

[0032] As shown in FIG. 1, the harness wiring structure 1 has a branch wire 12 extending from a main wire 11 arranged in a vehicle, a position control body 20 that controls the wiring path of the branch wire 12, and an electrical component 30 that is connected to the branch wire 12.

[0033] The trunk line 11 is a bundle of covered electric wires, each having a conductor surrounded by an insulating coating, and is arranged along the wiring direction L, and electrically connects the electrical equipment 30 mounted on the vehicle to other electrical equipment.

[0034] The branch wire 12 is a covered electric wire branched off from the trunk wire 11 toward the lower side Hd, and has a connector 13 attached to its tip for connection to the electrical equipment 30. Here, the point where the trunk wire 11 and the branch wire 12 branch off is referred to as a branch point 14.

[0035] The branch wire 12 will be described in detail. The branch wire 12 extends downward from the branch point 14 in a front view, and has a bent portion 121 that bends the tip side upward so that the connector 13 is disposed on the lower side Hd of the branch point 14.

[0036] Here, a portion on the base end side of the bent-back portion 121 and along the height direction H is referred to as a downward portion 122 , and a portion on the tip end side of the bent-back portion 121 is referred to as an upward portion 123 .

[0037] The length of the downward portion 122 in the height direction H is approximately twice the length of the upward portion 123 in the height direction H. Therefore, the connector 13 attached to the tip of the downward portion 122 is disposed on the lower side Hd of the branch point 14.

[0038] As shown in Figures 2(a) and 2(b), the position control body 20 has a shape combining an approximately triangular prism having a triangular shape when viewed from the front, which is arranged on the upper side Hu, and an approximately rectangular prism having a rectangular shape when viewed from the front, which is arranged on the lower side Hd.

[0039] In detail, the position regulating body 20 is integrally formed of a regulating body 21 which is a hollow rectangular column, an extending regulating portion 22 extending from the upper end of the rear side La of the regulating body 21 toward the upper side Hu, an inclined support portion 23 connecting the tip of the upper side Hu of the extending regulating portion 22 to the upper end of the front side Lb of the regulating body 21, a protruding wall portion 24 protruding from the upper end of the front side Lb of the regulating body 21 toward the upper side Hu, and an outer protruding portion 25 protruding outward in the wiring direction L from each vertex portion of the regulating body 21.

[0040] The regulating body 21 is a hollow prismatic body having a through hole having a rectangular shape in a plan view penetrating in the height direction H. In detail, the regulating body 21 is a prismatic body having a pair of side walls in the wiring direction L and a pair of side walls in the depth direction D, and the pair of side walls in the depth direction D and the side wall on the front side Lb are double walls formed by overlapping two side walls on the rear side La.

[0041] The length of the regulating body 21 along the wiring direction L is approximately twice the bending radius of the bent portion 121, and the length of the regulating body 21 along the height direction H is approximately twice the length along the wiring direction L. In addition, the length of the regulating body 21 along the depth direction D is slightly longer than the diameter of the branch wire 12 and approximately half the length of the regulating body 21 along the wiring direction L.

[0042] The extension restricting portion 22 is a plate-like member extending from an end portion of the rear side La of the restricting body 21 toward the upper side Hu. The length of the extension restricting portion 22 along the height direction H is approximately the same as the length of the restricting body 21 along the height direction H. In addition, the length of the extension restricting portion 22 along the depth direction D is shorter than the length of the restricting body 21 along the depth direction D and is approximately the same as the diameter of the branch wire 12.

[0043] The inclined support portion 23 is a plate-like member that inclines so as to move away from the extension restricting portion 22 as it approaches the downward side Hd, and connects an end portion of the upper side Hu of the extension restricting portion 22 to an inner wall of the front side Lb of the restricting body 21. The length and plate thickness of the inclined support portion 23 in the depth direction D are the same as the length and plate thickness of the extension restricting portion 22 in the depth direction D.

[0044] The protruding wall portion 24 is a plate-like member protruding from the outer wall of the front side Lb of the regulating body 21 toward the upper side Hu. The length of the protruding wall portion 24 in the depth direction D is approximately equal to the lengths of the extension regulating portion 22 and the inclined support portion 23 in the depth direction D. The plate thickness of the protruding wall portion 24 is also approximately equal to the plate thicknesses of the extension regulating portion 22 and the inclined support portion 23. The length of the protruding wall portion 24 in the height direction H is approximately half the length of the extension regulating portion 22 in the height direction H.

[0045] As shown in Fig. 2(b), the outer protrusion 25 is a plate-like body extending outward in the wiring direction L by a length substantially equal to the outer diameter of the branch wire 12. The plate thickness of the outer protrusion 25 is equal to the plate thickness of the extension restricting portion 22. The outer protrusions 25 thus configured are provided at each vertex of the restricting body 21 as described above. That is, the outer protrusions 25 are provided in pairs in the depth direction D.

[0046] The position regulating body 20 thus configured has flexibility allowing it to be bent, as shown in FIG. 3, and is assembled by folding a regulating body mold 50 that is punched out of an elastic sheet material 40.

[0047] The sheet material 40 is a thermoplastic resin foam sheet made of a synthetic resin foam molded into a foamed or porous shape, and has a predetermined rigidity as well as flexibility and plasticity. Since the sheet material 40 is configured in a sheet shape, it has excellent processability and is lighter than a molded resin (e.g., polypropylene) configured in the same shape as the position regulating body 20.

[0048] The density of the resin sheet constituting the sheet material 40 is not particularly limited, but for example, in order to prevent anisotropy of the mechanical properties, i.e., to make the mechanical properties isotropic and improve the freedom of design of the position control body 20, and also to further improve the strength against stress of the branch wire 12 regulated by the position control body 20, a density of 200 kg / m3 or more and 1000 kg / m3 or less is preferable, and in order to further improve the balance between light weight and mechanical strength, a density of 300 kg / m3 or more and 600 kg / m3 or less is more preferable, and a density of 350 kg / m3 or more and 650 kg / m3 or less is particularly preferable.

[0049] The thickness of the sheet material 40 is not particularly limited, but is preferably 0.50 mm or more and 4.0 mm or less, and particularly preferably 1.0 mm or more and 2.5 mm or less, from the viewpoint of further improving the balance between the ease of folding and the mechanical strength, in particular the mechanical strength against the stress on the branch wire 12 regulated by the position regulating body 20. The thermoplastic resin foamed sheet may have a non-foamed layer formed on both sides or one side.

[0050] That is, the sheet material 40 (thermoplastic resin foam sheet) may have a foam layer and a non-foam layer formed on the foam layer. The non-foam layer formed on the surface of the thermoplastic resin foam sheet improves the mechanical strength of the position regulating body 20. The thickness of the non-foam layer is not particularly limited, and may be, for example, 10 μm or more and 100 μm or less.

[0051] The bubble density of the foamed layer of the sheet material 40 is not particularly limited, and the lower limit is preferably 800 bubbles / mm3 or more, and particularly preferably 1000 bubbles / mm3 or more, from the viewpoint of more reliably preventing anisotropy of mechanical properties. On the other hand, the upper limit of the bubble density can be, for example, 1010 bubbles / mm3 or less, from the viewpoint of more reliably obtaining excellent mechanical strength.

[0052] As shown in Fig. 3(a), the sheet material 40 as described above has a strip-like rectangular shape, and a regulating body mold 50 is molded therein. The regulating body mold 50 will be described below with reference to Figs. 3(a) and 3(b). Here, the direction along the long side of the sheet material 40 is the longitudinal direction X, and the direction along the short side of the sheet material 40 is the short direction Y. The left side along the longitudinal direction X is one side Xa, and the right side along the longitudinal direction X is the other side Xb.

[0053] The regulating body mold 50 is integrally formed of a first rectangular mold 51 having a substantially rectangular shape, a first band-shaped mold 52 having a band shape along the longitudinal direction X, a second rectangular mold 53 having a substantially rectangular shape, and a second band-shaped mold 54 having a band shape along the longitudinal direction X. The first rectangular mold 51, the first band-shaped mold 52, the second rectangular mold 53, and the second band-shaped mold 54 are arranged in this order from one side Xa to the other side Xb.

[0054] The first rectangular mold 51 is composed of a rectangular first rectangular body 511 having a long side along the short direction Y and a short side along the longitudinal direction X, and four first extension portions 512 extending outward from the outer edge of the first rectangular body 511 in the longitudinal direction X.

[0055] The first rectangular body 511 corresponds to the side wall of the rear side La of the regulation body 21 and the outer walls at both ends in the depth direction D. That is, the first rectangular body 511 is rectangular in shape having a short side corresponding to the height of the regulation body 21 along the longitudinal direction X and a long side corresponding to the width of the side wall of the rear side La of the regulation body 21 and the inner walls disposed at both ends in the depth direction D along the transverse direction Y.

[0056] In addition, in the center portion of the longitudinal direction X of the first rectangular body 511, a pair of cutout portions 513, which are U-shaped cutouts opening outward in the lateral direction Y, are formed at a predetermined interval in the lateral direction Y. The cutout portions 513 are provided at an interval approximately equal to the width of the side wall of the rear side La of the regulation body 21.

[0057] The cut-out portion 513 thus provided in the first rectangular body 511 is composed of a pair of cuts along the short direction Y having a length equal to the thickness of the sheet material 40, and a cut that is cut so as to connect the inner ends in the longitudinal direction X of the cuts along the short direction Y.

[0058] The first extending portions 512 extend a predetermined length from both ends of the first rectangular main body 511 in the wiring direction L toward the outside, on the inside of the length along the depth direction D of the extension restricting portion 22 from both ends of the first rectangular main body 511 in the short side direction Y. That is, the first extending portions 512 are provided at positions corresponding to the notches 513 at the ends of the first rectangular main body 511 in the longitudinal direction X.

[0059] The first extending portion 512 configured in this manner is a strip-like rectangular shape having a long side along the longitudinal direction X and a short side along the lateral direction Y. The long side of the first extending portion 512 is approximately half the length of the first rectangular main body 511 along the longitudinal direction X, and the short side of the first extending portion 512 is sufficiently shorter than the long side of the first extending portion 512.

[0060] The first band-shaped mold 52 is formed in a band-like rectangular shape extending to the other side Xb from the central portion in the short-side direction Y of the first extending portion 512, more specifically, from between the first extending portions 512 extending in pairs on the other side Xb of the first rectangular main body 511. The long side of the first band-shaped mold 52 is the sum of the lengths of the extension restricting portion 22 and the inclined support portion 23, and the short side of the first band-shaped mold 52 is the same as the width of the extension restricting portion 22 (the length along the depth direction D).

[0061] The second rectangular mold 53 has substantially the same shape as the first rectangular mold 51, except that the second rectangular mold 53 does not have the notched portion 513 and the four corners of the first rectangular mold 51 are cut away. In detail, the second rectangular mold 53 is composed of a second rectangular main body 531 corresponding to the first rectangular main body 511 and a second extending portion 532 corresponding to the first extending portion 512.

[0062] As described above, the second rectangular body 531 has a rectangular shape with the four corners cut out, the same shape as the first rectangular body 511. Here, by cutting out the four corners of the second rectangular body 531, a protruding portion formed on the outer edge of the second rectangular body 531 in the short side direction Y is made into the insertion protruding portion 533. The length of the insertion protrusion 533 in the longitudinal direction X is equal to the length of the cutout 513 in the longitudinal direction X, and is configured so as to be press-fitted into the cutout 513 .

[0063] The second extending portion 532 has the same configuration as the first extending portion 512, and therefore a description thereof will be omitted here. In addition, the first band-shaped mold 52 connected to the second rectangular main body 531 is disposed between the second extending portions 532 on the one side Xa.

[0064] The second band-shaped mold 54, like the first band-shaped mold 52, is a band-like rectangular mold having a long side along the longitudinal direction X and a short side along the short direction Y, and extends from the central portion of the second rectangular main body 531 in the short direction Y toward the other side Xb. The long side of the second band-shaped mold 54 has a length equal to the sum of the height of the regulating body 21 and the height of the protruding wall portion 24, and the short side of the second band-shaped mold 54 has the same length as the short side of the first band-shaped mold 52.

[0065] The regulating body mold 50 thus punched out from the sheet material 40 can be folded at a predetermined location to form the position regulating body 20. Hereinafter, the imaginary mountain fold lines and imaginary valley fold lines for folding the regulating body mold 50 will be described with reference to FIG. 3(b).

[0066] 3(b), the first rectangular mold 51 has a first mountain fold line 61 that is a mountain fold line along the longitudinal direction X at the outer portion in the short side direction Y of the pair of cut portions 513. In addition, the first rectangular mold 51 has a first valley fold line 62 that is a valley fold line along the short side direction Y at the boundary portion between the first rectangular main body 511 and the first extending portion 512.

[0067] The first band-shaped mold 52 extending from the other side Xb of the first rectangular main body 511 has a second mountain fold line 63 that is mountain-folded along the short side direction Y at a position away from the boundary with the first rectangular main body 511 by a length substantially equal to the length of the first rectangular main body 511 along the longitudinal direction X. In addition, the first band-shaped mold 52 has a third mountain fold line 64 that is a mountain fold line that is mountain-folded along the short side direction Y at the boundary with the second rectangular mold 53.

[0068] The second rectangular mold 53 has a fourth mountain fold line 65 which is a pair of mountain fold lines along the longitudinal direction X so as to connect both ends of the first band-shaped mold 52 and the second band-shaped mold 54 in the longitudinal direction X. The second rectangular mold 53 also has a second valley fold line 66 which is a valley fold line along the transverse direction Y at the boundary between the second rectangular main body 531 and the second extending portion 532. The second rectangular mold 53 also has a third valley fold line 67 which is a valley fold line along the transverse direction Y at the boundary with the second band-shaped mold 54.

[0069] The position regulating body 20 can be assembled by folding the regulating body form 50 thus punched out from the sheet material 40 along the first mountain fold line 61, the first valley fold line 62, the second mountain fold line 63, the third mountain fold line 64, the fourth mountain fold line 65, the second valley fold line 66, and the third valley fold line 67. A method for assembling the position restriction body 20 will now be briefly described with reference to FIG.

[0070] First, the second rectangular body 531 is mountain-folded along the fourth mountain fold line 65 so that both end portions in the short side direction Y of the second rectangular body 531 are perpendicular to the center portion. In this manner, with the second rectangular mold 53 having a concave cross section, the first band-shaped mold 52 is mountain-folded along the second mountain fold line 63 and the third mountain fold line 64 so that the insertion protrusion 533 faces the cutout portion 513, and the insertion protrusion 533 is inserted into the cutout portion 513 (see FIG. 4(a)).

[0071] Next, the first rectangular body 511 is mountain-folded along the first mountain fold line 61 so that both end portions in the short side direction Y of the first rectangular body 511 overlap the outer surface of the second rectangular body 531 in the short side direction Y. Then, the second band-shaped mold 54 is valley-folded along the third valley fold line 67 so that it overlaps the outer surface of the central portion of the second rectangular body 531. As a result, the tip portion of the second band-shaped mold 54 protrudes beyond the connection portion between the second rectangular body 531 and the first band-shaped mold 52 (see FIG. 4(b)).

[0072] Finally, the first extending portion 512 and the second extending portion 532 are folded along the first valley fold line 62 and the second valley fold line 66, thereby assembling the position regulating body 20. More specifically, the base end portions of the first rectangular mold 51, the second rectangular mold 53, and the second band-shaped mold 54 in the regulating body mold 50 are folded to form the regulating body 21, which is a hollow prismatic body. The first band-shaped mold 52 in the regulating body mold 50 forms the extension regulating portion 22 and the inclined support portion 23 that form an acute angle, and the tip portion of the second band-shaped mold 54 forms the protruding wall portion 24 that protrudes from the regulating body 21 in the direction in which the extension regulating portion 22 and the inclined support portion 23 are arranged relative to the regulating body 21. The first extending portion 512 and the second extending portion 532 form the outer extending portion 25 that extends outward from each vertex of the prismatic body 21.

[0073] The position regulating body 20 formed by assembling the regulating body mold 50 punched out from the sheet material 40 in this manner is attached to the branch wire 12 and fixed with tape T to form the harness wiring structure 1, as shown in Figure 5. More specifically, the position regulating body 20 is disposed so that the outer protrusions 25 protrude along the wiring direction L in a front view, and the downward portion 122 is sandwiched between the outer protrusions 25 on the rear side La and moved to the downward side Hd. Then, the position regulating body 20 is disposed on the lower side Hd of the connector 13 and on the upper side Hu of the bent-back portion 121. At this time, the upward portion 123 is sandwiched between the outer protrusions 25 on the front side Lb (see FIG. 5(b)).

[0074] This allows the downward portion 122 and the upward portion 123 to be clamped by the outer protrusions 25 provided at each vertex of the regulating body 21, so that the position regulating body 20 can be attached to the branch wire 12 without the position regulating body 20 being misaligned relative to the branch wire 12.

[0075] After arranging the position regulating body 20 between the downward portion 122 and the upward portion 123, the tape T is wound around the outer protrusions 25 arranged to face each other along the height direction H. This ensures that the regulating body 21 is securely fixed to the branch wire 12, thereby preventing the position regulating body 20 from moving unintentionally in the height direction H. In addition, since the downward portion 122 and the upward portion 123 are sandwiched between the outer protrusions 25 provided on the upper side Hu and the lower side Hd, the position regulating body 20 can be prevented from rotating about a rotation axis along the wiring direction L or the height direction H.

[0076] In this way, since the regulating body 21, which is a rectangular column, is fixed on the side Hd below the connector 13 and on the side Hu above the bent-back portion 121, the downward portion 122 and the upward portion 123 can be prevented from approaching each other on the side Hd below the connector 13. In other words, on the side Hd below the connector 13, the distance between the downward portion 122 and the upward portion 123 can be maintained at a constant distance.

[0077] In addition, in a state where the restricting body 21 is fixed on the lower side Hd of the connector 13 and on the upper side Hu of the bent-back portion 121, the extension restricting portion 22 is disposed on the front side Lb of the downward portion 122. Therefore, it is possible to restrict the downward portion 122 from moving to the forward side Lb. This makes it possible to suppress the downward portion 122 from falling onto the upper side Hu of the connector 13 on the upper side Hu of the connector 13. Note that since the inclined support portion 23, which is on a straight line when viewed from the front, connects the end of the upper side Hu of the extension restricting portion 22 and the upper end of the forward side Lb of the restricting body 21, the inclined support portion 23 can support the extension restricting portion 22 even if an external force toward the forward side Lb acts on the extension restricting portion 22. Therefore, it is possible to further suppress the downward portion 122 from falling onto the connector 13.

[0078] In this way, the restricting body 21 can maintain a predetermined distance between the downward portion 122 and the upward portion 123, and the extension restricting portion 22 can prevent the downward portion 122 from falling toward the connector 13. For this reason, for example, even if the liquid W flows from the branch point 14 toward the downward portion 122, the liquid W (liquid W1) flows from the downward portion 122 to the bent portion 121 and drips from the curved portion of the bent portion 121 toward the downward side Hd, as shown in FIG.

[0079] In addition, the protruding wall portion 24 is disposed on the rear side La of the connector 13. Therefore, even if the liquid W (assumed to be liquid W2) flows from the downward portion 122 toward the connector 13 along the extension restricting portion 22, the protruding wall portion 24 can block the liquid W2 flowing toward the front side Lb below the connector 13. As a result, the liquid W2 flows along the restricting body 21 toward the lower side Hd and drips from the curved portion of the bent-back portion 121 toward the lower side Hd. Therefore, the liquid W can be prevented from entering the connector 13.

[0080] In this way, in the harness arrangement structure 1 in which the branch wire 12 having the connector 13 attached to its tip is arranged, the branch wire 12 is formed with a bent portion 121 which extends downward from the branch point 14 to the downward side Hd and bends the tip side toward the upward side Hu so as to position the connector 13 on the lower side Hd of the branch point 14. The branch wire 12 has a portion arranged along the height direction H on the base end side of the bent portion 121 as a downward portion 122, and a portion on the tip side of the bent portion 121 as an upward portion 123, and a position restricting body 20 is provided which restricts the relative positions of the downward portion 122 and the upward portion 123. The position restricting body 20 is provided with a restricting body 21 which restricts the downward portion 122 and the upward portion 123 to be separated from each other in the arrangement direction L, and an extension restricting portion 22 which restricts the portion of the downward portion 122 on the upper side Hu of the connector 13 from falling close to the connector 13.

[0081] The harness routing structure 1 and the position regulating body 20 configured in this manner can prevent the liquid W running down the branch wire 12 from unintentionally dripping onto the connector 13 and causing the connector 13 to become wet. In detail, the position of the downward portion 122 and the upward portion 123 can be regulated by the position regulating body 20 having a regulating body 21 and an extension regulating portion 22, so that with the downward portion 122 and the upward portion 123 of the bent back branch wire 12 spaced a predetermined distance apart in the wiring direction L, the downward portion 122 can be prevented from falling close to the connector 13 on the upper side Hu above the connector 13.

[0082] This prevents the downward portion 122 from covering the upper side Hu of the connector 13, and prevents the liquid W running down the branch wire 12 from dripping onto the connector 13 or the vicinity of the connection portion of the branch wire 12 with the connector 13. Therefore, it is possible to prevent the liquid W running down the downward portion 122 from unintentionally dripping onto the connector 13 and causing the connector 13 to become wet.

[0083] Furthermore, the restricting body 21 is provided between the downward portion 122 and the upward portion 123, on the lower side Hd of the connector 13, and the extending restricting portion 22 extends from the restricting body 21 to the upper side Hu along the downward portion 122. This allows the extending restricting portion 22 extending from the restricting body 21 to the upper side Hu to support the downward portion 122 over a predetermined range along the height direction H. This makes it possible to more reliably restrict the portion of the downward portion 122 on the upper side Hu than the restricting body 21 from falling toward the connector 13.

[0084] Furthermore, an inclined support portion 23 is provided to support the extension restricting portion 22, and the inclined support portion 23 connects the restricting body 21 and the extension restricting portion 22. As a result, the extension restricting portion 22 can be supported by the inclined support portion 23 connected to the restricting body 21, so that the downward portion 122 can be more reliably prevented from falling toward the connector 13.

[0085] In addition, the inclined support portion 23 is inclined so as to move away from the extension restriction portion 22 as it moves from the upper side Hu to the lower side Hd, and the lower end of the inclined support portion 23 is positioned below the connector 13 on the side Hd. As a result, the inclined support portion 23, the restriction body 21, and the extension restriction portion 22 are connected in a substantially triangular shape when viewed from a direction perpendicular to the wiring direction L and the height direction H, so that the inclined support portion 23 can more firmly support the extension restriction portion 22. Therefore, the downward portion 122 can be more reliably restricted from collapsing toward the connector 13.

[0086] In addition, since the lower end of the inclined support portion 23 is disposed on the side Hd below the connector 13, even if the liquid W that has run down the downward portion 122 flows from the extension restricting portion 22 to the inclined support portion 23, the liquid W can be guided to the side Hd below the connector 13. Therefore, the connector 13 can be more reliably prevented from becoming wet.

[0087] Furthermore, the position regulating body 20 is provided with a protruding wall portion 24 that protrudes toward the upper side Hu between the lower end of the inclined support portion 23 and the connector 13. As a result, the protruding wall portion 24 can prevent the liquid W that has flowed down the inclined support portion 23 from flowing toward the connector 13, thereby reliably preventing the connector 13 from becoming wet.

[0088] In addition, tape T is provided to fix position regulating body 20 to branch wire 12. This allows position regulating body 20 to be fixed to branch wire 12 via tape T, thereby preventing position regulating body 20 from unintentionally coming off branch wire 12. This makes it possible to maintain a state in which downward portion 122 of branch wire 12 is restricted from falling toward connector 13, and reliably prevents connector 13 from becoming wet.

[0089] Furthermore, since the position control body 20 is provided with an outer protrusion 25 that regulates the position of the tape T, the position of the tape T relative to the position control body 20 can be regulated, so that the tape T can be held at the desired position on the position control body 20.

[0090] Furthermore, since the position restriction body 20 is provided with the outer protrusion 25 that holds the branch wire 12, it is possible to prevent the position restriction body 20 from unintentionally falling off the branch wire 12. Furthermore, when fixing the position regulating body 20 and the branch wire 12 with the tape T, the position regulating body 20 can be disposed at a desired position on the branch wire 12 and the tape T can be attached. In other words, the task of fixing the position regulating body 20 to the branch wire 12 can be easily performed.

[0091] Moreover, the position regulating body 20 is formed by folding the sheet material 40. Since the sheet material 40 can be easily processed, the position regulating body 20 can be easily formed in accordance with the shape of the branch wire 12. Therefore, the productivity of the harness routing structure 1 can be improved.

[0092] In the configuration of the present invention and the correspondence between the above-mentioned embodiment, the connector of the present invention corresponds to the connector 13, and the same applies below. The wire harness supports 12 branches. The harness arrangement structure corresponds to harness arrangement structure 1.

[0093] For example, in this embodiment, the branch wire 12 is a single insulated electric wire extending from the trunk wire 11 which is a bundle of insulated electric wires, but it may also be a bundle of insulated electric wires extending from the trunk wire 11, a communication cable such as an optical fiber cable for transmitting information, or a bundle of communication cables. Although the branch line 12 is led out from the trunk line 11, it may be led out from an electric junction box, an electric component, or the like.

[0094] Furthermore, the tape T may be a cable tie, a band clamp, or the like, as long as it can fix the position regulating body 20 to the branch wire 12. Further, the inclined support portion 23 is integrally connected to an end portion of the upper side Hu of the extension restricting portion 22, but may be connected to the inside of the extension restricting portion 22 in the height direction H. Note that the inclined support portion 23 does not necessarily have to be inclined as long as it connects the extension restricting portion 22 and the restricting body 21. Further, the inclined support portion 23 is connected to the upper end of the extension restricting portion 22, but may be connected to a location other than the end portion of the extension restricting portion 22, for example, a central portion of the extension restricting portion 22 in the height direction H and an end portion of the restricting body 21 on the front side Lb. Further, the position regulating body 20 is assembled by folding the regulating body mold 50 punched out from the sheet material 40, but it may be a resin molded product. [Explanation of symbols]
