Description

[Technical field]

[0001] The present invention relates to a wire harness. [Background technology]

[0002] For wire harnesses, exterior materials are essential to protect the electric wires from external structures such as steel plates of a vehicle. In conventional wire harnesses, various types of exterior materials are used to protect the electric wires. For example, the wire harness described in Patent Document 1 includes an electric wire bundle and a molded body integrally provided on a mounting portion that is a part of the axial direction of the electric wire bundle, and the molded body is made of a thermoplastic resin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-160568 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional wire harnesses, there are many types of exterior members, and many of them cannot be attached to the electric wires without human hands. In other words, there are many types of exterior members, but some of them require manual adjustment of the position of the wiring material such as the electric wires to be placed in an appropriate position on the exterior member. For this reason, there is room for improvement in the conventional wire harness in terms of attachment of the exterior member to the wiring material.

[0005] The present invention has been made in consideration of the above, and aims to provide a wire harness in which the arrangement position of the wiring material relative to the outer casing member can be easily positioned at an appropriate position and the outer casing member can be attached to the wiring material. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the wire harness of the present invention comprises a conductive wiring material and a molded member that covers the wiring material and is integral with the wiring material, and the molded member has a plurality of slits formed from the outer surface of the molded member toward the side where the wiring material is located. Effect of the Invention

[0007] In the wire harness according to the present invention, the molded member that covers the wiring material and is integral with the wiring material has a plurality of slits formed from the outer surface of the molded member toward the side where the wiring material is located. Therefore, when the molded member that is the exterior member of the wiring material is molded using a metal mold, the rib for forming the slits of the molded member in the metal mold can regulate the position of the wiring material relative to the molded member. As a result, by molding the molded member using a metal mold, the wiring material can be placed at an appropriate position in the molded member without manually adjusting the position of the wiring material while covering any position of the wiring material with the molded member. As a result, the effect is achieved that the placement position of the wiring material relative to the molded member that is the exterior member of the wiring material can be easily placed at an appropriate position, and the molded member can be attached to the wiring material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] FIG. 1 is a perspective view of a wire harness WH according to an embodiment. FIG. 2 is a side view of the wire harness WH shown in FIG. 1. The wire harness WH according to the present embodiment is arranged in a vehicle or the like. The wire harness WH is, for example, a bundle of wiring materials W used for power supply and signal communication for connection between devices mounted on a vehicle, and is configured to electrically connect the wiring materials W to each device using a connector or the like. The wire harness WH includes a plurality of wiring materials W having electrical conductivity, and a molded member 1 integrally provided around the plurality of wiring materials W so as to bundle the plurality of wiring materials W. The wire harness WH may further include various components such as exterior members such as a corrugated tube, a resin tape, and a protector, an electrical connection box, and a fixing device.

[0011] The wiring material W is composed of, for example, a metal rod, an electric wire, an electric wire bundle, etc. The metal rod is a rod-shaped member having electrical conductivity. The electric wire is a conductor portion (core wire) made of a plurality of conductive metal strands. The electric wire bundle is a bundle of such electric wires. Each wiring material W may be covered with an insulating coating portion.

[0012] The molded member 1 is provided as an exterior member for the wiring materials W. The molded member 1 is provided around the wiring materials W to cover the wiring materials W so as to bundle them along a predetermined direction in which the wiring materials W extend (hereinafter referred to as the extension direction X). The molded member 1 is formed of an insulating elastic resin material (e.g., ethylene-propylene-diene rubber (EPDM) or the like) having low rigidity and high flexibility, such as rubber or a thermoplastic elastomer. The molded member 1 is provided integrally around the wiring materials W so that the elastic resin material bundles the wiring materials W by molding. Therefore, the wire harness WH can have flexibility together with the molded member 1. The molded member 1 covers a portion of the wiring materials W collectively, and the portion of the wiring materials W is buried. In addition, the covering portion that constitutes the wiring material W is typically an insulating covering member provided over the entire length of the wiring material W, whereas the molded member 1 is a protective member that is provided further outside of such a covering member at a necessary location on the wiring material W for protecting the wiring material W, regulating the route, etc.

[0013] In this embodiment, the molded member 1 is formed in a substantially cylindrical shape with the axial direction being along the extension direction X of the wiring material W. A plurality of wiring materials W are arranged inside the molded member 1 around the axis of the cylinder that is the shape of the molded member 1.

[0014] Furthermore, in the molded member 1 according to this embodiment, a protrusion 5, which is a gate mark when the molded member 1 is formed by injection molding, protrudes from the outer surface 2 of the molded member 1 and is formed on a part of the outer surface 2. That is, the protrusion 5 formed on the outer surface 2 of the molded member 1 is a mark of a resin material injected into a mold 20 (see FIG. 6) when the molded member 1 is injection molded using the mold 20. The protrusion 5 is formed on the outer surface 2 near the center of the molded member 1 in the extension direction X of the wiring material W.

[0015] The molded member 1 has a plurality of slits 3 formed from an outer surface 2 of the molded member 1 toward the side where the wiring material W is located. In other words, the molded member 1 covers the plurality of wiring materials W, and the wiring materials W are disposed inside the molded member 1, so that the plurality of slits 3 formed in the molded member 1 are formed from the outer surface 2 of the molded member 1 toward the inside of the molded member 1.

[0016] The multiple slits 3 thus formed in the molded member 1 are formed such that the longitudinal direction of the slits 3 is perpendicular to the extension direction X of the wiring material W. In other words, each slit 3 is formed such that the width direction of the slit 3 is the extension direction X of the wiring material W.

[0017] The slits 3 are formed on both sides of the wiring material W in the molded member 1. Specifically, a plurality of slits 3 are formed on both sides of the wiring material W in a direction perpendicular to the extension direction X of the wiring material W, including the direction in which the protrusion 5 is formed. The slits 3 formed on both sides of the wiring material W are formed at positions different from each other in the extension direction X of the wiring material W.

[0018] In other words, when the slits 3 formed on both sides of the wiring material W are defined as the first slits 3a, and the slits 3 formed on the side opposite to the side where the protrusion 5 is located relative to the wiring material W are defined as the second slits 3b, the first slits 3a and the second slits 3b are located at different positions in the extension direction X of the wiring material W. In this embodiment, the first slits 3a and the second slits 3b formed in the molded member 1 are alternately formed in the extension direction X of the wiring material W.

[0019] Further, the first slits 3a are arranged at equal intervals on both sides of the protrusion 5 in the extension direction X of the wiring material W. Similarly, the second slits 3b are arranged at equal intervals on both sides of the protrusion 5 in the extension direction X of the wiring material W.

[0020] 3 is a cross-sectional view taken along line AA in FIG. 1. FIG. 4 is a perspective view of the main part including the cross-section taken along line BB in FIG. 1. FIG. 5 is a perspective view of the main part including the cross-section taken along line CC in FIG. 1. The slits 3 formed in the molded member 1, both the first slit 3a and the second slit 3b, are formed in a range of half the circumference of the molded member 1, that is, in a range of about 180°, centered on the axis of the cylinder, which is the shape of the molded member 1, when viewed in the extension direction X of the wiring material W. In this way, the first slit 3a and the second slit 3b formed in the range of half the circumference of the cylinder are formed at different positions in the circumferential direction centered on the axis of the cylinder, and are formed in a range that does not substantially overlap with each other in the circumferential direction.

[0021] In addition, the shape of the bottom 3c of the slit 3 of both the first slit 3a and the second slit 3b is formed in a substantially arc shape that is concentric with the outer surface 2 of the molded member 1 when viewed in the extension direction X of the wiring material W. Furthermore, the depth of the slit 3 from the outer surface 2 of the molded member 1 to the bottom 3c of the slit 3 is shallower than the depth from the outer surface 2 of the molded member 1 to the position where the wiring material W is arranged. In other words, the wiring material W is arranged at a position deeper from the outer surface 2 of the molded member 1 than the depth from the outer surface 2 of the molded member 1 to the bottom 3c of the slit 3.

[0022] Therefore, the resin material forming the molded member 1 is interposed between the wiring material W arranged inside the molded member 1 and the bottom 3c of the slit 3. As a result, even at the position where the slit 3 is formed in the extension direction X of the wiring material W, the wiring material W is not exposed in the slit 3 and is arranged inside the molded member 1 while being covered with the resin material forming the molded member 1.

[0023] FIG. 6 is a perspective view of a die 20 used to mold the molded member 1. FIG. 7 is a perspective view showing a state where the upper die 20a and the lower die 20b of the die 20 shown in FIG. 6 are separated. FIG. 8 is a perspective view of the upper die 20a and the lower die 20b shown in FIG. 7 as viewed from the lower die 20b side. The molded member 1 of the wire harness WH is molded using a die 20 having a molding section 21 for molding the molded member 1. In this embodiment, the die 20 has an upper die 20a and a lower die 20b, and when molding the molded member 1, molding is performed with the upper die 20a and the lower die 20b overlapping in the vertical direction. That is, the upper die 20a is overlapped from above with the lower die 20b.

[0024] A plurality of positioning pins 25 are arranged on the opposing surfaces of the upper and lower dies 20a and 20b to align the upper and lower dies 20a and 20b when they are overlapped. The positioning pins 25 are arranged on the lower die 20b by fitting into the lower die 20b, and are formed on the surface of the lower die 20b facing the upper die 20a, protruding toward the side where the upper die 20a is located. The upper die 20a is formed with positioning holes 26 at positions corresponding to the positioning pins 25, and when the upper die 20a and the lower die 20b are overlapped during molding of the molded member 1, the positioning is performed by inserting the positioning pins 25 into the positioning holes 26.

[0025] The molding portion 21 for molding the molded member 1 is formed in both the upper die 20a and the lower die 20b. In detail, the first molding portion 21a, which is the molding portion 21, is formed on the surface of the upper die 20a facing the lower die 20b, and the second molding portion 21b, which is the molding portion 21, is formed on the surface of the lower die 20b facing the upper die 20a. The first molding portion 21a and the second molding portion 21b are formed in a shape that can mold the outer surface 2 of the molded member 1. The first molding portion 21a and the second molding portion 21b are each formed in a shape that can mold the outer surface 2 of the molded member 1 in a range of about 180° in the circumferential direction of the cylinder, which is the shape of the molded member 1.

[0026] Ribs 22 for forming slits 3 in the molded member 1 are arranged in the molding section 21 of the metal mold 20. A first rib 22a, which is a rib 22 for forming the first slit 3a in the molded member 1, is arranged in the first molding section 21a, and a second rib 22b, which is a rib 22 for forming the second slit 3b in the molded member 1, is arranged in the second molding section 21b. The first rib 22a and the second rib 22b are formed at a certain height from the surface that forms the outer surface 2 of the molded member 1 in the first molding section 21a and the second molding section 21b, respectively.

[0027] The upper die 20a is also formed with an insertion hole 20aa for inserting a nozzle (not shown) of an injection device (not shown) when injecting a resin material into the die 20 during molding of the molded member 1. The insertion hole 20aa is formed as a hole communicating with the first molding portion 21a from the surface of the upper die 20a opposite to the surface facing the lower die 20b.

[0028] Next, the molding of the molded member 1 using the metal mold 20 will be described. FIG. 9 is a cross-sectional view of the metal mold 20 shown in FIG. 6 at the position of the wire harness WH. When molding the molded member 1 using the metal mold 20, the upper metal mold 20a and the lower metal mold 20b are overlapped in a state in which the wiring material W passes through the inside of the first molding portion 21a of the upper metal mold 20a and the second molding portion 21b of the lower metal mold 20b. At that time, since the first rib 22a is formed in the first molding portion 21a of the upper metal mold 20a and the second rib 22b is formed in the second molding portion 21b of the lower metal mold 20b, the wiring material W is arranged inside the molding portion 21 without being biased toward the upper metal mold 20a side or the lower metal mold 20b side.

[0029] That is, since the first molding portion 21a has the first rib 22a, the movement of the wiring material W toward the side where the upper mold 20a is located is restricted by the first rib 22a, and the deviation of the wiring material W toward the direction closer to the upper mold 20a is restricted by the first rib 22a. Similarly, since the second molding portion 21b has the second rib 22b, the movement of the wiring material W toward the side where the lower mold 20b is located is restricted by the second rib 22b, and the deviation of the wiring material W toward the direction closer to the lower mold 20b is restricted by the second rib 22b.

[0030] In addition, since the first rib 22a and the second rib 22b are formed at a constant height from the surface forming the outer surface 2 of the molded member 1 in the first molded portion 21a and the second molded portion 21b, the deviation of the wiring material W in each direction perpendicular to the extension direction X of the wiring material W is also restricted by the first rib 22a and the second rib 22b. As a result, the wiring material W arranged inside the molded portion 21 is arranged at a position near the axis of the cylinder, which is the shape of the molded member 1.

[0031] When molding the molded member 1 using the metal mold 20, the wiring material W is passed inside the molding portion 21 in this manner, and the upper metal mold 20a and the lower metal mold 20b are overlapped, and the molten resin material is injected into the molding portion 21. The resin material is injected into the molding portion 21 by inserting a nozzle of an injection device into an insertion hole 20aa formed in the upper metal mold 20a, and injecting the molten resin material from the nozzle, thereby injecting the resin material into the molding portion 21. As a result, the resin material is filled into the space formed by the first molding portion 21a of the upper metal mold 20a and the second molding portion 21b of the lower metal mold 20b.

[0032] The resin material filled in the molding section 21 hardens by cooling over time. As a result, the resin material is formed into the molded member 1 that covers the wiring material W arranged inside. When the resin material in the molding section 21 hardens to form the molded member 1, the upper metal mold 20a and the lower metal mold 20b are separated from each other to remove the molded member 1 formed by the metal mold 20.

[0033] Here, since the resin material is not filled at the position of the rib 22 formed in the molding portion 21 of the mold 20, the portion where the rib 22 is arranged in the molding portion 21 is formed as a slit 3 in the molded member 1. That is, the portion where the first rib 22a is arranged in the first molding portion 21a is formed as a first slit 3a in the molded member 1, and the portion where the second rib 22b is arranged in the second molding portion 21b is formed as a second slit 3b in the molded member 1. As a result, a plurality of slits 3 aligned in the extension direction X of the wiring material W are formed in the molded member 1 molded by the mold 20. Note that, depending on the position of the wiring material W when the molded member 1 is injection molded with respect to the wiring material W, a part of the wiring material W may be in contact with the rib 22 during molding, and a part of the wiring material W may be exposed to the bottom 3c side in the slit 3.

[0034] The wire harness WH having the molded member 1 thus molded using the metal mold 20 is routed in any part of a vehicle or the like. At that time, the molded member 1 is easily flexible due to the presence of the multiple slits 3. Therefore, the wire harness WH can be easily routed by bending the molded member 1 as necessary depending on the surrounding conditions of the part of the wire harness WH where the molded member 1 is to be disposed.

[0035] In addition, since the molded member 1 has the protrusions 5, when the molded member 1 is to be placed at a desired position, the positioning can be determined by the protrusions 5. This allows the molded member 1 to be placed at an appropriate position when the wire harness WH is routed.

[0036] In the wire harness WH according to the above embodiment, the molded member 1, which covers the wiring material W and is integral with the wiring material W, has a plurality of slits 3 formed from the outer surface 2 of the molded member 1 toward the side where the wiring material W is located. Therefore, when the molded member 1 is molded using the metal mold 20, the rib 22 for forming the slits 3 of the molded member 1 in the metal mold 20 can regulate the position of the wiring material W relative to the molded member 1. As a result, by molding the molded member 1 using the metal mold 20, the wiring material W can be placed at an appropriate position in the molded member 1 without manually adjusting the position of the wiring material W while covering any position of the wiring material W with the molded member 1. As a result, the wiring material W can be easily placed at an appropriate position relative to the molded member 1, and the molded member 1 can be attached to the wiring material W.

[0037] In addition, since the slits 3 formed in the molded member 1 are perpendicular to the extension direction X of the wiring material W, the molded member 1 can be easily bent in a direction perpendicular to the extension direction X of the wiring material W. As a result, when the molded member 1 is injection molded for the wiring material W, the ribs 22 forming the slits 3 can more effectively suppress the wiring material W from coming apart. In addition, when the molded member 1 is arranged at an arbitrary position, the molded member 1 can be bent as necessary to improve the ease of arrangement. As a result, the ease of wiring the wire harness WH can be improved.

[0038] In addition, since the slits 3 are formed on both sides of the wiring material W in the molded member 1, the molded member 1 can be easily bent toward the side where both slits 3 are arranged. In other words, since the molded member 1 has the first slit 3a and the second slit 3b formed on the opposite sides of the molded member 1, when the molded member 1 is injection molded with respect to the wiring material W, the first rib 22a forming the first slit 3a and the second rib 22b forming the second slit 3b can more suitably suppress the scattering of the wiring material W from both sides. In addition, since the molded member 1 has the first slit 3a and the second slit 3b, it can be easily bent toward the side where the first slit 3a is arranged and the side where the second slit 3b is arranged. As a result, since the molded member 1 can be bent in a plurality of directions when arranging the molded member 1 at an arbitrary position, the arrangement of the molded member 1 can be improved. As a result, the ease of wiring the wire harness WH can be improved.

[0039] In addition, since the slits 3 on both sides of the wiring material W are formed at different positions in the extension direction X of the wiring material W, the slits 3 can be easily provided on both sides of the wiring material W. This allows the molded member 1 to be easily bent in multiple directions, improving the ease of arrangement when arranging the molded member 1 at an arbitrary position. As a result, the ease of wiring the wire harness WH can be improved.

[0040] In addition, the first slits 3a and the second slits 3b formed in the molded member 1 are alternately formed in the extension direction X of the wiring material W, so that the bendability of the molded member 1 can be improved when bending the molded member 1. In other words, the first slits 3a and the second slits 3b are alternately formed in the extension direction X of the wiring material W, so that the molded member 1 can be bent with a small radius of curvature when bending. This improves the ease of arrangement when arranging the molded member 1 at an arbitrary position. As a result, the ease of wiring the wire harness WH can be improved.

[0041] [Variations] In the above embodiment, the slits 3 formed in the molded member 1 are formed in a direction perpendicular to the extension direction X of the wiring material W, but the slits 3 may be formed in other directions. FIG. 10 is a plan view of the molded member 1 in which the slits 3 are inclined with respect to the extension direction X of the wiring material W, which is a modification of the wire harness WH according to the embodiment. FIG. 11 is a plan view of the molded member 1 in which the second slits 3b are inclined in the same direction as the first slits 3a, which is a modification of the wire harness WH according to the embodiment. FIG. 12 is a plan view of the molded member 1 in which the second slits 3b are inclined in a direction different from the first slits 3a, which is a modification of the wire harness WH according to the embodiment. The multiple slits 3 formed in the molded member 1 may be formed, for example, inclined with respect to the extension direction X of the wiring material W and the direction perpendicular to the extension direction X of the wiring material W, as shown in FIGS. 10 to 12. In other words, the multiple first slits 3a formed in the molded member 1 may be formed at an angle with respect to the extension direction X of the wiring material W and a direction perpendicular to the extension direction X of the wiring material W, as shown in Figure 10.

[0042] In this case, the second slit 3b formed on the side opposite to the side on which the first slit 3a is formed in the molded member 1 may be inclined in the same direction as the first slit 3a with respect to the extension direction X of the wiring material W, as shown in Figure 11, or the second slit 3b may be inclined in a direction different from the direction in which the first slit 3a is inclined with respect to the extension direction X of the wiring material W, as shown in Figure 12.

[0043] The slits 3 of the molded member 1 are formed at an incline with respect to the extension direction X of the wiring material W, so that when bending the molded member 1, it is possible to bend the molded member 1 in an oblique direction according to the inclination direction of the slits 3. As a result, when, for example, a plurality of slits 3 are inclined in the same direction with respect to the extension direction X of the wiring material W, the molded member 1 can be bent in a spiral shape as a whole by bending the molded member 1 in the same oblique direction for each position of the slits 3. Since the bending direction of the molded member 1 can be made oblique by inclining the slits 3 with respect to the extension direction X of the wiring material W in this way, it is possible to bend the molded member 1 according to the arrangement position of the molded member 1 by inclining the slits 3 according to the arrangement position of the molded member 1. Therefore, it is possible to improve the arrangement when arranging the molded member 1 at an arbitrary position. As a result, it is possible to improve the ease of wiring the wire harness WH.

[0044] In addition, when the slits 3 are formed at an angle with respect to the extension direction X of the wiring material W, all of the slits 3 formed in the molded member 1 do not have to be inclined with respect to the extension direction X of the wiring material W. Of the multiple slits 3 formed in the molded member 1, some of the slits 3 may be inclined with respect to the extension direction X of the wiring material W, and other slits 3 may be perpendicular to the extension direction X of the wiring material W. Since the slits 3 formed in the molded member 1 affect the bending direction of the molded member 1, it is preferable that the multiple slits 3 are formed at an appropriate angle for each slit 3 depending on the arrangement position and arrangement form of the molded member 1.

[0045] In the above embodiment, the slits 3 are formed on both sides of the wiring material W in the molded member 1, but the slits 3 may be formed only on one side of the molded member 1 in a direction perpendicular to the extension direction X of the wiring material W. FIG. 13 is a side view of the molded member 1 in which the second slits 3b are formed, which is a modified example of the wire harness WH according to the embodiment. The multiple slits 3 formed in the molded member 1 may be, for example, as shown in FIG. 13, in which the first slits 3a are not formed and only the second slits 3b are formed. The molded member 1 can ensure the ease of bending by forming the second slits 3b on one side of the molded member 1 in a direction perpendicular to the extension direction X of the wiring material W.

[0046] In addition, since the slit 3 is not formed at the other side of the molded member 1 in the direction perpendicular to the extension direction X of the wiring material W, the protective performance of the wiring material W can be improved on the side where the slit 3 is not formed. As a result, when the side on which the protective performance of the wiring material W in the molded member 1 is to be improved is determined, the slit 3 is not formed on the side on which the protective performance is to be improved, and the slit 3 is formed only on the opposite side, thereby achieving both the protective performance of the wiring material W and the ease of bending the molded member 1. As a result, it is possible to achieve both the protective performance of the wiring material W by the molded member 1 and the ease of wiring the wire harness WH.

[0047] In the above-described embodiment, the slits 3 formed in the molded member 1 are formed over the entire range in the extension direction X of the wiring material W, but the slits 3 do not have to be formed over the entire range of the molded member 1. Fig. 14 is a plan view of the molded member 1 in which a fixing portion 10 for attaching the molded member 1 to an attachment target portion is disposed, which is a modified example of the wire harness WH according to the embodiment. When the molded member 1 is provided with the fixing portion 10 for attaching the molded member 1 to an attachment target portion as shown in Fig. 14, it is preferable that the slits 3 are formed at a position other than the position where the fixing portion 10 is disposed in the molded member 1.

[0048] In this case, the attachment target portion is a portion of the vehicle where the molded member 1 is attached. The fixing portion 10 is made of, for example, a clamp or clip, and can be attached to the attachment target portion directly or by using a bolt or the like. The fixing portion 10 does not have to be a separate body from the molded member 1, and may be formed integrally with the molded member 1.

[0049] In this way, the fixing portion 10 is disposed in the molded member 1, and the slit 3 is not provided at the position where the fixing portion 10 is disposed in the molded member 1, thereby ensuring strength in the vicinity of the fixing portion 10 in the molded member 1. This ensures the attachment strength when the molded member 1 is attached to the attachment target portion by the fixing portion 10.

[0050] In addition, by forming the slit 3 at a position other than the position where the fixing portion 10 is arranged in the molded member 1, the bias of the wiring material W can be restricted by the rib 22 that forms the slit 3 in the mold 20. This allows the wiring material W to be arranged at an appropriate position in the molded member 1. In addition, by forming the slit 3 at a position other than the position where the fixing portion 10 is arranged in the molded member 1, the molded member 1 can be easily bent, so that the arrangement of the molded member 1 can be improved. As a result, the arrangement position of the wiring material W relative to the molded member 1 can be easily arranged at an appropriate position, and the molded member 1 can be attached to the wiring material W, and the mounting strength of the molded member 1 and the ease of wiring the wire harness WH can be improved.

[0051] In the above embodiment, six first slits 3a and seven second slits 3b are formed in the molded member 1, but the numbers of the first slits 3a and the second slits 3b may be other than these. In the above embodiment, the first slits 3a and the second slits 3b are arranged at equal intervals on both sides of the protrusion 5 in the extension direction X of the wiring material W, but the first slits 3a and the second slits 3b do not have to be arranged at equal intervals.

[0052] In the above embodiment, the first slit 3a is formed on the upper side and the second slit 3b is formed on the lower side when the side where the protrusion 5 is located in the molded member 1 is defined as the upper side, but the first slit 3a and the second slit 3b may be formed at positions other than the upper side and the lower side. When the side where the protrusion 5 is located in the molded member 1 is defined as the upper side, the first slit 3a and the second slit 3b may be formed on the side opposite to each other. It is preferable that the first slit 3a and the second slit 3b are appropriately arranged depending on the position where the molded member 1 is arranged and the bending manner of the molded member 1 according to the arrangement form.

[0053] In the above-described embodiment, the molded member 1 directly covers the wiring material W, but the molded member 1 may cover the wiring material W covered with an insulating coating or an outer coating. As long as the molded member 1 can cover a portion of the wiring material W, it does not matter whether the wiring material W itself has an insulating coating or an outer coating.

[0054] The wire harness according to the embodiment and the modified example of the present invention described above is not limited to the embodiment and the modified example described above, and various modifications are possible within the scope of the claims. The wire harness according to the embodiment and the modified example may be configured by appropriately combining the components of the embodiment and the modified example described above.
