[0039] Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiments. In addition, the constituent elements of the following embodiments include elements that can be easily replaced by those skilled in the art, or substantially the same elements.

[0040] [Example]

[0041] Figure 1 、 Figure 2 The wire harness WH of this embodiment shown is installed in a vehicle, for example. The wire harness WH bundles multiple wiring members W used for power supply and signal communication, for example, to connect various devices installed in the vehicle. Connectors and other devices electrically connect the wiring members W to the devices. The wire harness WH of this embodiment includes: multiple conductive wiring members W; and a molded component 1 integrally disposed around the wiring members W, bundling the wiring members W.

[0042] The wiring material W is, for example, an insulated wire formed by covering a core wire W1, which is a bundle of multiple conductive metal wires, with an insulating sheath W2. Alternatively, the wiring material W may be a bundle of multiple insulated wires. Alternatively, the wiring material W may be an insulated metal rod formed by covering a conductive metal rod with an insulating sheath. The molded component 1 covers the wiring material W and is integrally provided with the wiring material W, serving as an exterior component for the wiring material W. The wiring harness WH may also include various other components, such as a corrugated tube, grommets, and an electrical junction box.

[0043] Furthermore, the molded component 1 of this embodiment includes, in addition to the portion covering the wiring material W, a plate-shaped anchor portion 12 for securing to the target location 100, thereby improving workability during vehicle installation. The various components of the molded component 1 will be described in detail below with reference to the various figures.

[0044] Here, the fixing target site 100 to which the anchor portion 12 is fixed is provided, for example, on a routing surface 101 of various structural components, such as a vehicle body, where the wire harness WH is routed. In this embodiment, the fixing target site 100 includes a fixing recess 102 formed in a recessed shape on the routing surface 101, into which the anchor portion 12 is inserted and fixed. The fixing recess 102 has a barbed portion 102b formed at the edge of an opening 102a on the routing surface 101 side. The barbed portion 102b is formed in a claw-like shape at the edge of the opening 102a, protruding from a side wall 102c of the fixing recess 102 toward the inside of the opening 102a.

[0045] Specifically, if Figure 1 、 Figure 2As shown, the molded component 1 is constructed to include: a main body 11, an anchor portion 12, and a connecting portion 13. The molded component 1 is formed of an elastic resin material (for example, ethylene propylene diene monomer (EPDM)) with low rigidity and high flexibility, such as rubber or thermoplastic elastomer. In the molded component 1, the elastic resin material is molded by injection molding or the like, and is integrally arranged around the plurality of wiring materials W in a manner that bundles the plurality of wiring materials W, so that the main body 11, the anchor portion 12, the connecting portion 13, and other parts are directly integrally molded with the wiring materials W. Therefore, the wire harness WH can have flexibility together with the molded component 1. Here, as an example, the main body 11, the anchor portion 12, the connecting portion 13, and other parts in the molded component 1 are formed into a straight line along the extension direction X of the wiring material W.

[0046] The main body 11 covers the exterior of the wiring material W and constitutes the primary portion that functions as an exterior component for the wiring material W. The main body 11 is positioned along the extension direction X of the plurality of wiring materials W and holds the plurality of wiring materials W in a bundled manner. Typically, the main body 11 covers and protects the plurality of wiring materials W and restricts the path along which the plurality of wiring materials W are laid. The main body 11 covers and buries portions of the plurality of wiring materials W.

[0047] As an example, Figure 1 As shown, the main body 11 of this embodiment is formed in a substantially cylindrical shape, with the direction along the axis C being aligned with the extending direction X of the wiring material W. The main body 11 is provided so as to cover the entire circumference of each wiring material W. The plurality of wiring materials W are arranged within the main body 11 around the axis C, which is the cylindrical shape of the main body 11.

[0048] The insulating covering portion W2 constituting the wiring material W is typically an insulating covering member provided over substantially the entire length of the wiring material W in the extending direction X. In contrast, the main body portion 11 is a protective member provided locally at a necessary location in the wiring material W, further outside the insulating covering portion W2 serving as such a covering member, for the purposes of protecting the wiring material W, regulating its path, and the like.

[0049] The anchor portion 12 is formed into a plate shape and is fixed to the target fixing portion 100. It constitutes a secondary portion that functions as an exterior component of the wiring material W. The anchor portion 12 is formed into a plate shape so as to be elastically deformable along the plate thickness direction Y. Furthermore, the anchor portion 12 can be inserted into a fixing recess 102 formed in the target fixing portion 100 and fixed.

[0050] The anchor portion 12 of this embodiment is formed into a substantially rectangular plate shape with the plate thickness direction Y being perpendicular to the extending direction X of the wiring material W, and is located opposite to the main body 11 in the plate thickness direction Y. Here, the anchor portion 12 is connected to the main body 11 via the connecting portion 13. In addition, as an example, Figure 2 As shown, the anchor portion 12 of this embodiment is provided along the outer peripheral surface of the main body 11 over substantially the entire length thereof in the extending direction X of the wiring material W. The anchor portion 12 is inserted into and secured in the fixing recess 102, thereby securing the entire molded component 1 including the main body 11 to the fixing target portion 100.

[0051] The connecting portion 13 is a portion that connects the main body 11 and the anchor portion 12. The connecting portion 13 is located between the main body 11 and the anchor portion 12 in the plate thickness direction Y of the anchor portion 12, and functions as a portion that connects the main body 11 and the anchor portion 12 along the plate thickness direction Y. Here, the connecting portion 13 is formed as a portion that is narrowed between the main body 11 and the anchor portion 12 in the molded component 1 so as not to hinder the elastic deformation of the anchor portion 12 along the plate thickness direction Y. As an example, Figure 2 As shown, the connection portion 13 of this embodiment is provided along the outer peripheral surface of the main body portion 11 over substantially the entire length in the extending direction X of the wiring material W, similarly to the anchor portion 12 .

[0052] As an example, the molded component 1 constructed as described above is Figure 1 The illustrated layout fixing method is fixed to the fixing target portion 100. In this case, the molded component 1 is inserted into the fixing recess 102 by bending the anchor portion 12 while elastically deforming in the plate thickness direction Y and pressing it into the fixing recess 102.

[0053] And, in Figure 1 In the illustrated arrangement and fixing method, when the anchor portion 12 of the molded component 1 is inserted into the fixing recess 102, the elastically deformed anchor portion 12 returns to its original shape, resting on the bottom wall 102d of the fixing recess 102. Furthermore, in this state, the plate-shaped end 12a of the anchor portion 12 of the molded component 1 is engaged with the barb-shaped portion 102b formed at the edge of the opening 102a of the fixing recess 102. This structure prevents the anchor portion 12 from being removed from the fixing recess 102 even when an external force acts in a direction that would cause the anchor portion 12 to separate from the fixing recess 102, by hooking and engaging the barb-shaped portion 102b. As a result, the molded component 1 can maintain its fixation to the target site 100 via the anchor portion 12.

[0054] The wire harness WH described above protects the wiring material W and restricts the routing path of the wiring material W by virtue of the main body 11 of the molded component 1, which is integrally formed to cover the wiring material W. In this configuration, the wire harness WH is inserted and secured into the fixing recess 102 of the fixing target portion 100 while elastically deforming the anchor portion 12 of the molded component 1. This allows the entire molded component 1 to be fixedly supported to the fixing target portion 100, such as the routing surface 101, via the anchor portion 12. As a result, the wire harness WH can be appropriately routed to a predetermined location in the vehicle while reducing work hours and ensuring adequate workability, compared to, for example, a method of fixing the wiring material W to the fixing target portion 100 by separately attaching a fixing member such as a band clip or a clip.

[0055] Furthermore, the wire harness WH can fix the main body 11 of the molded component 1 to the fixing target portion 100 via the anchor portion 12 while the main body 11 is exposed from the fixing recess 102 rather than being housed in the fixing recess 102 .

[0056] Furthermore, the wire harness WH forms the molded component 1 through injection molding (molding) rather than extrusion. This allows, for example, the wiring material W to be directly formed into a molded component 1 of various shapes on a jig plate using a mold during the manufacturing process. This eliminates the need for manual assembly of protective components such as protectors, allowing the wire harness WH to be automatically manufactured using various manufacturing equipment. Consequently, the manufacturing efficiency of the wire harness WH is improved, and injection molding (molding) on a jig plate can facilitate automation of the manufacturing process.

[0057] In the wire harness WH described above, the molded component 1 includes a connecting portion 13 that connects the main body 11 and the anchor portion 12. With this configuration, the wire harness WH, with the connecting portion 13 interposed between the main body 11 and the anchor portion 12, can be configured so that the anchor portion 12 is less likely to interfere with the main body 11 when elastically deforming in the plate thickness direction Y. As a result, the wire harness WH can be properly routed while ensuring adequate workability.

[0058] Furthermore, in the wire harness WH described above, when the anchor portion 12 is inserted into the fixing recess 102, the plate-shaped end portion 12a of the anchor portion 12 is locked with the barb-shaped portion 102b formed on the edge of the opening 102a of the fixing recess 102. This configuration prevents the anchor portion 12 from being removed from the fixing recess 102 by hooking and locking the plate-shaped end portion 12a with the barb-shaped portion 102b, even when an external force acts on the molded component 1 in a direction that would cause the anchor portion 12 to be removed from the fixing recess 102. As a result, the wire harness WH can maintain the molded component 1 secured to the fixing target portion 100 via the anchor portion 12, thereby maintaining a properly routed state.

[0059] It should be noted that the wire harness according to the embodiment of the present invention described above is not limited to the above embodiment, and various modifications can be made within the scope of the claims.

[0060] While the above description describes that the main body 11, anchor 12, and connecting portion 13 of the molded component 1 are formed linearly along the extending direction X of the wiring material W, the present invention is not limited thereto. The molded component 1 may also be formed such that the main body 11, anchor 12, and connecting portion 13 are bent or curved according to the routing path of the wiring material W.

[0061] In the above description, anchor portions 12 and connecting portions 13 are provided along substantially the entire length of main body 11 in the extension direction X of wiring material W, but the present invention is not limited thereto. For example, multiple anchor portions 12 and connecting portions 13 may be provided locally at required locations in main body 11 and spaced apart along extension direction X.

[0062] In the above description, the main body 11 is described as being provided so as to cover the entire circumference of each wiring member W. However, the present invention is not limited thereto. The main body 11 may not cover the entire circumference of each wiring member W, and may be formed, for example, to partially cover the wiring member W along its circumference.

[0063] In the above description, the anchor portion 12 is formed into a substantially rectangular plate shape with the plate thickness direction Y being perpendicular to the extending direction X of the wiring material W. However, the present invention is not limited thereto and the anchor portion 12 may be formed into a plate shape other than a rectangle.

[0064] In the above description, as an example, the molded component 1 is described as follows. Figure 1 The example of the layout fixing method is fixed to the fixed object part 100, but is not limited to this. Figure 3 、 Figure 4 Another example of the arrangement and fixing method will be described.

[0065] Figure 3 The wire harness WHA according to the illustrated modification differs from the aforementioned wire harness WH in the shape of the applied fixing portion 100A and the method of routing and fixing the molded component 1. Fixing portion 100A to which wire harness WHA is applied differs from fixing portion 100 described above in that fixing recess 102A is deeper than fixing recess 102 described above and that barbed portions 102b are absent. The remaining structures of wire harness WHA and fixing portion 100A are substantially the same as those of wire harness WH and fixing portion 100.

[0066] As an example, the molded component 1 of the wire harness WHA of this modification is Figure 3 The illustrated layout fixing method is fixed to the fixing target portion 100A. In this case, the molded component 1 is inserted into the fixing recess 102A by pressing the anchor portion 12 into the fixing recess 102A with each plate-shaped end portion 12a being bent while elastically deforming toward the bottom wall 102d, with the anchor portion 12 connected to the connecting portion 13 as the base point.

[0067] Furthermore, the molded part 1 is Figure 3 In the illustrated arrangement and fixing method, when the anchor portion 12 is inserted into the fixing recess 102A and elastically deformed, the plate-shaped ends 12a of the anchor portion 12 contact the inner wall surface, i.e., the side walls 102c, of the fixing recess 102A. Furthermore, in this state, the plate-shaped ends 12a of the anchor portion 12 are pressed against the side walls 102c due to the elastic restoring force of the molded component 1. In other words, in this state, the anchor portion 12 is bent into a roughly V-shape and pressed into the fixing recess 102A, and is positioned slightly spaced from the bottom wall 102d of the fixing recess 102A. With this configuration, even when an external force acts in a direction that would cause the anchor portion 12 to separate from the fixing recess 102A, the molded component 1 can prevent the anchor portion 12 from separating from the fixing recess 102A due to the frictional resistance generated between the plate-like end portions 12a and the side walls 102c. As a result, the molded component 1 can maintain its fixation to the fixing target portion 100A via the anchor portion 12.

[0068] Even the wire harness WHA described above can be appropriately routed to a predetermined position of the vehicle, similarly to the wire harness WH described above.

[0069] In this case, while the anchor portion 12 is inserted into the fixing recess 102A and elastically deformed, the wire harness WHA described above contacts the side wall 102c of the fixing recess 102A. This structure allows the wire harness WHA to prevent the anchor portion 12 from being removed from the fixing recess 102A, even when an external force acts on the molded component 1 in a direction that would cause the anchor portion 12 to be removed from the fixing recess 102A. The frictional resistance generated between the plate-shaped end portions 12a and the side walls 102c prevents the anchor portion 12 from being removed from the fixing recess 102A. As a result, the wire harness WHA maintains the molded component 1 secured to the fixing target portion 100A via the anchor portion 12, maintaining its proper routing.

[0070] Figure 4 The wire harness WHB according to the illustrated modified example differs from the aforementioned wire harness WHA in that it includes a molded component 1B in place of the molded component 1, and in the method of routing and securing molded component 1B. Molded component 1B differs from molded component 1 in that connecting portion 13B is formed relatively longer than connecting portion 13. The remaining structures of the wire harness WHB, molded component 1B, and connecting portion 13B are substantially the same as those of the wire harness WHA, molded component 1, and connecting portion 13.

[0071] As an example, the molded component 1B of the wire harness WHB according to this modification is Figure 4 The illustrated routing and fixing method is fixed to the target fixing portion 100A. In this case, the molded component 1B is pressed into the fixing recess 102 with the anchor portion 12 bent in the opposite direction to that of the wire harness WHA described above. Specifically, the molded component 1B is inserted into the fixing recess 102A by elastically deforming the anchor portion 12 while bending the plate-like ends 12a toward the opening 102a, with the anchor portion 12 being connected to the connecting portion 13B as the starting point.

[0072] Furthermore, the molded part 1B is Figure 4 In the example of the layout and fixing method, Figure 3Similar to the case of the anchor portion 12 inserted into the fixing recess 102A and elastically deformed, the plate-shaped ends 12a of the anchor portion 12 contact the inner wall surface of the fixing recess 102A, namely the side walls 102c. Furthermore, in this state, the plate-shaped ends 12a of the anchor portion 12 are pressed against the side walls 102c by the elastic restoring force of the molded component 1B. In other words, in this state, the anchor portion 12 is bent into a substantially V-shape and pressed into the fixing recess 102A, and is positioned slightly spaced from the bottom wall 102d of the fixing recess 102A. With this structure, even when an external force acts in a direction that would cause the anchor portion 12 to detach from the fixing recess 102A, the frictional resistance generated between the plate-shaped ends 12a and the side walls 102c prevents the anchor portion 12 from detaching from the fixing recess 102A. Furthermore, in this case, the folded-back plate-like ends 12a of the molded component 1B face the opening 102a. Therefore, when the anchor portion 12 moves toward the opening 102a and attempts to separate from the fixing recess 102A, the folded-back plate-like ends 12a themselves resist the movement of the anchor portion 12 toward the expanded state accompanying the pulling action, thereby further preventing separation from the fixing recess 102A. As a result, the molded component 1B can maintain its fixation to the fixing target portion 100A via the anchor portion 12.

[0073] The wire harness WHB described above can also be appropriately routed at a predetermined position in the vehicle, similar to the wire harnesses WH and WHA described above. Furthermore, in this case, similar to the wire harness WHA described above, the wire harness WHB can maintain the state in which the molded component 1B is fixed to the fixing target portion 100A via the anchor portion 12, thereby maintaining the appropriately routed state.

[0074] In the above description, the molded components 1 and 1B are described as including the connecting portions 13 and 13B. However, the present invention is not limited thereto and may be configured without the connecting portions 13 and 13B.

[0075] Figure 5The wire harness WHC according to the illustrated modification differs from the aforementioned wire harness WH in that it includes a molded component 1C without connecting portions 13, 13B, etc., instead of the molded component 1, and in the shape and layout of the fixed portion 100C used. The fixed portion 100C to which the wire harness WHC is applied differs from the aforementioned fixed portion 100 in that the depth of the fixed recess 102C is deeper than the fixed recess 102 described above. Furthermore, the depth of the fixed recess 102C is shallower than the fixed recess 102A described above. The remaining structures of the wire harness WHC and the fixed portion 100C are substantially the same as those of the wire harness WH and the fixed portion 100.

[0076] Furthermore, the molded component 1C of this variation differs from the aforementioned molded component 1 in that it lacks the connecting portion 13 and includes an anchor portion 12C in place of the anchor portion 12. Specifically, the anchor portion 12C of this variation is directly connected to the outer peripheral surface of the main body 11, not via connecting portions 13, 13B, etc. The anchor portion 12C of this variation protrudes from the main body 11 in a direction perpendicular to the extension direction X and the plate thickness direction Y. Here, the anchor portion 12C is formed to protrude from the outer peripheral surface of the main body 11 in a plate-like shape, positioned so as to contact the outer peripheral surface of the main body 11. The remaining structures of the molded component 1C and the anchor portion 12C are substantially the same as those of the molded component 1 and the anchor portion 12.

[0077] As an example, the molded component 1C of the wire harness WHC according to this modification is Figure 5 The illustrated routing and fixing method is fixed to the fixing target portion 100C. In this case, similar to the case of the wire harness WH described above, the molded component 1C is bent while elastically deforming in the plate thickness direction Y and pressed into the fixing recess 102C, so that the anchor portion 12C is inserted into the fixing recess 102C.

[0078] And, in Figure 5In the illustrated arrangement and fixing method, the molded component 1C returns to its original shape after elastically deforming the anchor portion 12C while it is inserted into the fixing recess 102C. Furthermore, in this state, the molded component 1C is held by the plate-shaped end 12a of the anchor portion 12C being engaged with the barbed portion 102b formed at the edge of the opening 102a of the fixing recess 102C, with the barbed portion 102b sandwiched between the plate-shaped end 12a and the main body 11. In other words, in this state, the molded component 1C is fixed in position with the barbed portion 102b sandwiched between the plate-shaped end 12a and the main body 11, and is positioned slightly spaced from the bottom wall 102d of the fixing recess 102C. With this configuration, even when an external force acts in a direction that would cause the anchor portion 12C to separate from the fixing recess 102C, the plate-shaped end portion 12a is hooked and locked onto the barb-shaped portion 102b, thereby preventing the anchor portion 12C from separating from the fixing recess 102C. As a result, the molded component 1C can maintain its fixation to the fixing target site 100C via the anchor portion 12C.

[0079] Even the wire harness WHC described above can be appropriately routed to a predetermined position of the vehicle, similarly to the wire harnesses WH, WHA, and WHB described above.

[0080] In this case, the wire harness WHC described above is formed so that the anchor portion 12C protrudes from the main body portion 11. With this structure, the wire harness WHC can fix the position of the molded component 1C by, for example, sandwiching the barb-shaped portion 102b of the fixing recess 102C between the plate-shaped end portion 12a of the anchor portion 12C and the main body portion 11, thereby maintaining a properly routed state.

[0081] While the above description describes that the main body 11 of the molded components 1, 1B, and 1C is formed in a substantially cylindrical shape, with the direction along the axis C being aligned with the extending direction X of the wiring material W, the present invention is not limited thereto. The main body 11 may be formed, for example, in a polygonal column shape, or may be formed in an irregular shape depending on the shape of obstacles surrounding the main body 11 so as not to interfere with the obstacles.

[0082] Figure 6The wire harness WHD according to the illustrated modification differs from the aforementioned wire harness WH in that it includes a molded component 1D in place of the molded component 1, and in the shape of the applied fixing portion 100C and the method of routing and fixing the molded component 1D. The remaining structure of the wire harness WHD is substantially the same as that of the wire harness WH. Furthermore, the fixing portion 100C applied to the wire harness WHD has the same structure as the fixing portion 100C applied to the aforementioned wire harness WHC.

[0083] Furthermore, the molded component 1D of this modified example differs from the molded component 1 described above in that it includes a main body 11D in place of the main body 11. The main body 11D of this modified example differs from the main body 11 in that it is formed in a substantially quadrangular prism shape, with the direction along the axis C corresponding to the direction X along which the wiring material W extends. Here, the main body 11D is provided so as to cover the entire circumference of each wiring material W. Multiple wiring materials W are arranged within the main body 11D around the axis C of the quadrangular prism, which is the shape of the main body 11D. The remaining structures of the molded component 1D and the main body 11D are substantially the same as those of the molded component 1 and the main body 11.

[0084] As an example, the molded component 1D of the wire harness WHD according to this modification is Figure 6 The illustrated routing and fixing method is fixed to the fixing target portion 100C. In this case, similar to the case of the wire harness WH described above, the molded component 1D is bent while elastically deforming in the plate thickness direction Y and pressed into the fixing recess 102C, so that the anchor portion 12 is inserted into the fixing recess 102C.

[0085] And, in Figure 6In the illustrated arrangement and fixing method, the molded component 1D is held in place by having the anchor portion 12 inserted into the fixing recess 102C. The elastically deformed anchor portion 12 returns to its original shape. Furthermore, in this state, the molded component 1D is held in place by having the plate-shaped end 12a of the anchor portion 12 engage with the barbed portion 102b formed at the edge of the opening 102a of the fixing recess 102C, with the barbed portion 102b sandwiched between the plate-shaped end 12a and the outer surface of the main body 11D facing the anchor portion 12. In other words, in this state, the molded component 1D is fixed in place by having the barbed portion 102b sandwiched between the plate-shaped end 12a and the outer surface of the main body 11D facing the anchor portion 12, and is positioned slightly spaced from the bottom wall 102d of the fixing recess 102C. With this configuration, even when an external force acts in a direction that would cause the anchor portion 12 to separate from the fixing recess 102C, the molded component 1D can prevent the anchor portion 12 from separating from the fixing recess 102C by hooking and locking the plate-shaped end portion 12a with the barb-shaped portion 102b. As a result, the molded component 1D can maintain its fixation to the fixing target site 100C via the anchor portion 12.

[0086] Even the wire harness WHD described above can be appropriately routed to a predetermined position of the vehicle, similarly to the wire harnesses WH, WHA, WHB, and WHC described above.

[0087] In this case, the wire harness WHD described above can, for example, positionally fix the molded component 1D by sandwiching the barbed hook-shaped portion 102b of the fixing recess 102C between the plate-shaped end portion 12a of the anchor portion 12 and the outer surface of the main body 11D opposite to the anchor portion 12, thereby maintaining a properly laid state.

[0088] The wire harness of the present embodiment can also be configured by appropriately combining the components of the above-described embodiments and modified examples.
