[0044] 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 in the following embodiments include elements that can be easily replaced by those skilled in the art, or substantially the same elements.

[0045] [Implementation Method]

[0046] The present embodiment relates to a wiring harness. In the following description, the first direction among the mutually intersecting first direction, second direction and third direction is referred to as the "extension direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the extension direction X, the width direction Y and the height direction Z are mutually orthogonal. The extension direction X is equivalent to the extension direction and the length direction of the flexible substrate of the trunk module. The width direction Y is equivalent to the width direction of the flexible substrate of the trunk module. The height direction Z is equivalent to the thickness direction of the flexible substrate of the trunk module. The width direction Y and the height direction Z are equivalent to the intersection direction intersecting with the extension direction X. In addition, the directions used in the following description represent the directions in the state where the parts are assembled to each other unless otherwise specified. In addition, the orthogonal mentioned here includes substantially orthogonal.

[0047] A wire harness according to the first embodiment will be described.

[0048] Figure 1 1 is a perspective view of a wire harness WH according to the first embodiment, and shows a state in which the wire harness WH is assembled in a vehicle 100. For example, the wire harness WH is installed inside an instrument panel 110 of the vehicle 100 for use. The instrument panel 110 is an interior panel disposed at the front of the vehicle interior along the vehicle width direction in a manner facing the driver's seat and the passenger seat of the vehicle 100. Figure 1In the figure, the instrument panel 110 is indicated by a double-dotted chain line. The wire harness WH connects the devices mounted on the vehicle 100 and is used for power supply and signal communication. A reinforcement 111 is provided inside the instrument panel 110. The reinforcement 111 is a structural component or a reinforcing component provided inside the instrument panel 110, and is provided along the vehicle width direction (extension direction X). The reinforcement 111 is also referred to as a reinforcement, a reinforcement, a reinforcement, etc. The reinforcement 111 is, for example, composed of a hollow metal tube, and flanges 112 are formed at both ends. One flange 112 is fixed to the left side of the vehicle body 100, and the other flange 112 is fixed to the right side of the vehicle body 100.

[0049] The wiring harness WH includes a trunk module 10 and a plurality of branch modules 20. The trunk module 10 is a wiring module having a plurality of transmission lines or wirings extending in the same direction, for example, connected to a control unit, etc. The trunk module 10 includes a flexible substrate 11 and a plurality of trunk side connectors 12. The flexible substrate 11 is a planar circuit body that forms a circuit in a planar shape, and is called a flexible printed wiring board (FPC (Flexible Printed Circuits: Flexible Printed Circuit)), which is a printed wiring substrate with flexibility. The planar shape mentioned here also includes a substantially planar shape. The flexible substrate 11 is formed, for example, by bonding a base film, a conductor foil, and a covering layer via an adhesive layer. The conductor foil is a wiring pattern of the flexible substrate 11, and constitutes a wiring portion of the flexible substrate 11. The flexible substrate 11 can be a single-sided substrate having a wiring pattern only on one side of the base film, or a double-sided substrate having a wiring pattern on both sides of the base film. In addition, the flexible substrate 11 can be installed with electrical components such as resistors and capacitors on the wiring pattern, or it can be installed without electrical components.

[0050] Here, the trunk module 10 is connected to an ECU (Electronic Control Unit) 51 via any one of a plurality of trunk side connectors 12, and is connected to a branch module 20 via another trunk side connector 12. The ECU 51 here is a first control unit, typically a regional ECU that uniformly controls devices in a peripheral area (region) of the instrument panel 110, but is not limited thereto. The trunk side connector 12 is a connector mounted on an end of the flexible substrate 11.

[0051] The plurality of branch line modules 20 are wiring modules each having one end connected to the trunk line side connector 12 of the trunk line module 10 and the other end connected to various electronic devices 40 in the vehicle 100. The branch line modules 20 are each configured to include: a plurality of wiring materials 21 having electrical conductivity (see Figure 2); a first branch line side connector 22, which is provided at one end of the plurality of wiring materials 21, and is mechanically and electrically connected to each trunk line side connector 12; a second branch line side connector 23, which is provided at the other end of the plurality of wiring materials 21, and is mechanically and electrically connected to various electronic devices 40 in the vehicle 100. The wiring material 21 is, for example, an electric wire having a conductor portion formed by twisting a plurality of linear metal wires and an insulating covering portion covering the outer side of the conductor portion. In addition, the wiring harness WH may also have a special wire 30. The special wire 30 is an electric wire that transmits a signal or power that is difficult to properly transmit in the flexible substrate 11, such as a signal for high-speed communication or a large current power. The special wire 30 is laid, for example, along the reinforcement 111.

[0052] Figure 2 FIG. 1 is a schematic top view of the wire harness WH. The flexible substrate 11 is formed as a whole in a rectangular shape that is long in the vehicle width direction. That is, the flexible substrate 11 has a pair of first end portions 11a as long sides and a pair of second end portions 11b as short sides. The first end portions 11a are the front and rear ends of the flexible substrate 11 (in the vehicle front and rear direction). Figure 2 The second end 11b is the end of the flexible substrate 11 in the vehicle width direction (in the width direction Y). Figure 2 In the present embodiment, the plurality of trunk line side connectors 12 are provided at least one at each of the first end 11a and the second end 11b of the flexible substrate 11.

[0053] Specifically, the trunk module 10 has, for example, seven trunk side connectors 12. Moreover, here, four trunk side connectors 12 are provided at intervals from each other in the vehicle width direction at one of the pair of first end portions 11a, and one trunk side connector 12 is provided at the other. In addition, one trunk side connector 12 is provided at one of the pair of second end portions 11b, and one trunk side connector 12 is provided at the other. Six of these trunk side connectors 12 are connected to the branch module 20 via the above-mentioned branch side first connector 22, and the remaining one is connected to the ECU 51 via the ECU side connector. In addition, specifications such as the number of poles of the trunk side connector 12, the configuration of the trunk side connector 12 in the flexible substrate 11, etc. can be appropriately changed according to the installation position of the wire harness WH in the vehicle 100, etc.

[0054] exist Figure 1 In the embodiment, the flexible substrate 11 is arranged along the reinforcing member 111 and assembled to the reinforcing member. For example, the flexible substrate 11 may be directly assembled to the reinforcing member 111 or assembled via other components. The flexible substrate 11 may be assembled to the reinforcing member 111 such that the back side faces the surface of the reinforcing member 111.

[0055] One end of the flexible substrate 11 extends to the position of one end 111A of the reinforcement 111, and the other end extends to the position between the central position 111B and the other end 111C of the reinforcement 111. For example, one end of the flexible substrate 11 extends beyond the position of one end 111A of the reinforcement 111 to the position of the ECU 51. In addition, the other end of the flexible substrate 11 extends to the position beyond the central position 111B of the reinforcement 111 and is connected to the first wire module 201. The first wire module 201 is a part of the branch module 20 and has a wiring material 21 as an electric wire. After the first wire module 201 is wired along the reinforcement 111, it is detached from the reinforcement 111 and connected to the ECU 52. The ECU 52 is a second control unit, and is typically a regional ECU that uniformly controls the devices in the peripheral area (ゾーン) of the instrument panel 110, but is not limited to this.

[0056] Next, the assemblability of the wire harness WH according to the present embodiment will be described.

[0057] like Figure 1 As shown, the wire harness WH involved in this embodiment uses a flexible substrate 11 in the trunk module 10. Moreover, the flexible substrate 11 is arranged and assembled along the reinforcement 111. Therefore, the wire harness WH involved in this embodiment can eliminate the three-dimensional wiring of the flexible substrate 11, and the assembly of the flexible substrate 11 becomes easy. That is, the wire harness WH involved in this embodiment does not need to perform three-dimensional wiring of the flexible substrate 11, so the flexible substrate 11 with low rigidity and strength can be easily assembled. Therefore, the wire harness WH involved in this embodiment can improve the assemblability.

[0058] In addition, the wire harness WH according to the present embodiment can reduce or thin the installation space of the trunk module 10 by assembling the flexible substrate 11 along the surface of the reinforcement member 111. Therefore, the interior space of the vehicle can be effectively utilized.

[0059] In the wire harness WH involved in the present embodiment, the flexible substrate 11 is set from one end 111A of the reinforcement 111 to the position between the central position 111B and the other end 111C in the trunk module 10. That is, the wire harness WH involved in the present embodiment can suppress the use of the high-cost flexible substrate 11 by using the flexible substrate 11 locally relative to the reinforcement 111 in the trunk module 10, and can be formed thinner in the height direction at the driver's seat and the central position. Therefore, the wire harness WH involved in the present embodiment can achieve the miniaturization of the instrument panel 110. That is, the wire harness WH involved in the present embodiment can reduce or thin the installation space of the wire harness WH in the interior of the instrument panel 110, in the area between the back of the steering wheel and the center of the vehicle. Therefore, the wire harness WH involved in the present embodiment can help to suppress the height of the instrument panel 110.

[0060] As described above, the wire harness WH of the present embodiment can eliminate three-dimensional wiring of the flexible substrate 11 by assembling the flexible substrate 11 to the reinforcing member 111, thereby facilitating assembly of the flexible substrate 11. Therefore, the wire harness WH according to the present embodiment can improve assemblability.

[0061] In addition, the wire harness WH of this embodiment can suppress the use of the high-cost flexible substrate 11 by locally using the flexible substrate 11 relative to the reinforcement 111 in the trunk module 10, and can be formed thinner in the height direction at the driver's seat and the central position, thereby realizing the miniaturization of the instrument panel 110.

[0062] Next, a wire harness according to a second embodiment will be described.

[0063] Figure 3 1 is a perspective view of a wire harness WHA according to a second embodiment, and shows a state in which the wire harness WHA is assembled in a vehicle 100. The wire harness WHA according to the second embodiment is configured substantially the same as the wire harness WH according to the first embodiment, but the installation range of the flexible substrate 11 with respect to the reinforcement 111 in the trunk module 10 is different. That is, in the wire harness WHA according to the second embodiment, the flexible substrate 11 is arranged from the position of one end 111A of the reinforcement 111 to the position of the other end 111C. That is, the flexible substrate 11 is provided in the entire section of the reinforcement 111. Here, the entire section includes substantially the entire section.

[0064] A first wire module 201 is connected to the other end of the flexible substrate 11, and a second wire module 202 is connected to one end. The first wire module 201 and the second wire module 202 are wiring modules that use the wiring material 21 as a wire as a transmission line. The first wire module 201 is connected to the flexible substrate 11 at the position of the end 111C of the reinforcement 111, and is configured to be separated from the reinforcement 111, for example, connected to the ECU 52. The second wire module 202 is connected to the flexible substrate 11 at the position of the end 111A of the reinforcement 111, and is configured to be separated from the reinforcement 111, for example, connected to the ECU 51.

[0065] The wire harness WHA according to the second embodiment has excellent assembly properties and can be easily assembled to a vehicle. That is, the wire harness WHA according to the second embodiment has high wiring properties by applying the flexible substrate 11 to the linear section of the reinforcement 111 in the trunk module 10, thereby achieving good vehicle mounting.

[0066] As described above, the wire harness WHA according to the second embodiment can improve assemblability by using the flexible substrate 11 in the section laid on the reinforcement 111 in the trunk module 10 .

[0067] Next, a wire harness WHB according to a third embodiment will be described.

[0068] Figure 4 : is a perspective view of a wire harness WHB according to the third embodiment, and shows a state of being assembled in a vehicle 100. The wire harness WHB according to the third embodiment is substantially similar to the wire harness WH according to the first embodiment, except that the setting range of the flexible substrate 11 relative to the reinforcement 111 in the trunk module 10 is different. Figure 4 As shown, in the wire harness WHB according to the third embodiment, the flexible substrate 11 is provided throughout the trunk module 10 . For example, when the trunk module 10 is provided from the ECU 51 to the ECU 52 , the flexible substrate 11 is provided throughout the section between the ECU 51 and the ECU 52 .

[0069] The flexible substrate 11 has a straight portion 11C and a bent portion 11D. The straight portion 11C is a portion formed in a straight line shape and is arranged with respect to the entire section from one end 111A to the other end 111C of the reinforcement 111. The bent portion 11D is a portion where the end of the straight portion 11C is folded back and arranged downward, and the end is connected to the ECU 51 or ECU 52. The bent portion 11D is, for example, a portion where the end of the straight portion 11C is folded back obliquely and bent downward to extend.

[0070] The wire harness WHB involved in the third embodiment provides the flexible substrate 11 throughout the entire section of the trunk module 10, thereby reducing the number of trunk side connectors 12 mounted on the flexible substrate 11. In addition, the wire harness WHB involved in the third embodiment provides the flexible substrate 11 throughout the entire section of the trunk module 10, thereby making the trunk module 10 thinner. That is, the trunk module 10 has a plurality of transmission lines, so if the wires are bundled to form it, it will be large-scale and thick. In contrast, in the wire harness WHB involved in the third embodiment, it can be made thinner than in the case where the trunk module 10 is bundled to form it.

[0071] As described above, the wire harness WHB according to the third embodiment can reduce the number of connector connection locations by providing the flexible substrate 11 throughout the entire section of the trunk module 10 .

[0072] Next, a wire harness according to a fourth embodiment will be described.

[0073] Figure 5: is a stereoscopic view of a wire harness WHC involved in a fourth embodiment, showing a state of being assembled in a vehicle 100. The wire harness WHC involved in the fourth embodiment is constructed in substantially the same manner as the wire harness WHA involved in the second embodiment described above, and differs in that it includes a first protective plate 61. That is, the wire harness WHC involved in the fourth embodiment includes a first protective plate 61 for protecting a flexible substrate 11 in a trunk module 10. The first protective plate 61 is a rectangular plate body extending long in one direction, and is formed of a material having higher rigidity than the flexible substrate 11. For example, the first protective plate 61 is formed of a resin. More specifically, the first protective plate 61 is formed of a resin having polyethylene as a main component, and is plastically deformed. That is, the first protective plate 61 can maintain the deformed shape when deformed according to the installation location.

[0074] like Figure 6 As shown, the first protective plate 61 is formed to be the same size or substantially the same size as the flexible substrate 11, and is disposed on the reinforcing member 111 side of the flexible substrate 11. For example, the flexible substrate 11 is attached to the first protective plate 61 using an adhesive, a double-sided tape, or the like. Figure 7 As shown, the first protection plate 61 is attached to the reinforcement member 111 using, for example, a clamp 63. The clamp 63 is inserted into the reinforcement member 111 and fixed to the reinforcement member 111. In addition, the clamp 63 is attached to the first protection plate 61 by bonding or tape winding.

[0075] The flexible substrate 11 is arranged, for example, from one end 111A to the other end 111C of the reinforcing member 111. That is, the flexible substrate 11 is provided in the entire section of the reinforcing member 111. Alternatively, the flexible substrate 11 may be provided in a partial section of the reinforcing member 111.

[0076] The wire harness WHC according to the fourth embodiment can protect the flexible substrate 11 by attaching the first protection plate 61 to the flexible substrate 11. In addition, in the wire harness WHC according to the fourth embodiment, the flexible substrate 11 is attached to the reinforcement 111 via the first protection plate 61, so the attachment state of the flexible substrate 11 is stable. In addition, since the flexible substrate 11 is in a plate shape, the first protection plate 61 can be formed in a plate shape and formed in a simple shape, and the protector of the flexible substrate 11 can be provided at low cost. In addition, the wire harness WHC according to the fourth embodiment can easily bend and hold the first protection plate 61 by forming the first protection plate 61 from resin, and can improve the assembly property to the reinforcement 111. In addition, the wire harness WHC according to the fourth embodiment can stably assemble the flexible substrate 11 by attaching the first protection plate 61 to the flexible substrate 11, so that it is easy to automatically assemble it to the vehicle.

[0077] As described above, the wire harness WHC according to the fourth embodiment includes the first protection plate 61 attached to the flexible substrate 11 , thereby being able to physically protect the flexible substrate 11 and being able to be appropriately assembled to the reinforcement member 111 .

[0078] Furthermore, the wire harness WHC according to the fourth embodiment includes the clamp 63 fixed to the reinforcement member 111 , and thus the flexible substrate 11 can be attached to the reinforcement member 111 using the clamp 63 .

[0079] Next, a wire harness according to a fifth embodiment will be described.

[0080] Figure 8 It is a stereoscopic view of the wire harness WHD involved in the fifth embodiment. The wire harness WHD involved in the fifth embodiment is constructed in substantially the same manner as the wire harness WHC involved in the fourth embodiment described above, and differs in that it includes a second protective plate 62. That is, the wire harness WHD involved in the fifth embodiment includes a second protective plate 62 for protecting the flexible substrate 11 in the trunk module 10. The second protective plate 62 is a rectangular plate body extending longer in one direction, and is formed of a material having higher rigidity than the flexible substrate 11. For example, the second protective plate 62 is formed of a resin. More specifically, the second protective plate 62 is formed of a resin having polyethylene as a main component, and is plastically deformed. That is, the second protective plate 62 can maintain the deformed shape when deformed according to the installation location.

[0081] like Fig. 9 as well as Fig.10 As shown, the second protective plate 62 is formed to be the same size or substantially the same size as the flexible substrate 11, and is arranged on the side of the flexible substrate 11 opposite to the reinforcing member 111. That is, the second protective plate 62 and the first protective plate 61 sandwich and protect the flexible substrate 11. For example, the second protective plate 62 is attached to the flexible substrate 11 using an adhesive, a double-sided tape, etc. In addition, an adhesive tape 64 is wound around the first protective plate 61 and the second protective plate 62. Through the adhesive tape 64, the first protective plate 61, the second protective plate 62 and the flexible substrate 11 are integrated, and the first protective plate 61 and the second protective plate 62 are prevented from being separated from the flexible substrate 11.

[0082] The flexible substrate 11 is arranged, for example, from one end 111A to the other end 111C of the reinforcing member 111. That is, the flexible substrate 11 is provided over the entire section of the reinforcing member 111. Alternatively, the flexible substrate 11 may be provided over a portion of the reinforcing member 111.

[0083] The wire harness WHD according to the fifth embodiment has the effects of the wire harness WHC according to the third embodiment, and further includes the second protection plate 62 that clamps and protects the flexible substrate 11 together with the first protection plate 61, thereby more reliably protecting the flexible substrate 11. In addition, the wire harness WHD according to the fifth embodiment can prevent the first protection plate 61 and the second protection plate 62 from falling off from the flexible substrate 11 by winding the mounting tape 64 around the first protection plate 61 and the second protection plate 62.

[0084] As described above, the wire harness WHD according to the fifth embodiment includes the second protection plate 62 that sandwiches and protects the flexible substrate 11 together with the first protection plate 61 , and thus can reliably protect the flexible substrate 11 .

[0085] Next, a wire harness according to a sixth embodiment will be described.

[0086] Fig.11 : is a perspective view of a wire harness WHE according to the sixth embodiment. The wire harness WHE according to the sixth embodiment is substantially similar to the wire harness WHD according to the fifth embodiment, but differs in that the flexible substrate 11 is arranged throughout the entire section of the reinforcement 111 and the flexible substrate 11 is arranged beyond the range of the reinforcement 111. In addition, in the wire harness WHE according to the sixth embodiment, the first protection plate 61 and the second protection plate 62 are also assembled to sandwich the flexible substrate 11 for the flexible substrate 11 arranged beyond the range of the reinforcement 111.

[0087] like Fig.12 As shown, the flexible substrate 11 of the wire harness WHE has a straight portion 11C and a bent portion 11D. The straight portion 11C is a portion formed in a straight line shape, and is arranged with respect to the entire section from one end 111A to the other end 111C of the reinforcement 111. The bent portion 11D is a portion in which the end of the straight portion 11C is folded back and arranged downward. The bent portion 11D is, for example, an end of the straight portion 11C is folded back obliquely and bent downward to extend.

[0088] The wire harness WHE according to the sixth embodiment provides the flexible substrate 11 throughout the trunk module 10, thereby reducing the number of trunk side connectors 12 mounted on the flexible substrate 11. In addition, the wire harness WHE according to the sixth embodiment provides the flexible substrate 11 throughout the trunk module 10, thereby making the trunk module 10 thinner.

[0089] like Fig.13As shown, the first protection plate 61 has a straight portion 61A and a bent portion 61B along the flexible substrate 11 having a straight portion 11C and a bent portion 11D. The straight portion 61A is a portion formed in a straight line shape, and is arranged with respect to the entire section from one end 111A to the other end 111C of the reinforcement member 111. The bent portions 61B are provided at both ends of the straight portion 61A, and are portions that are bent at each end and hang down downward.

[0090] In addition, the second protection plate 62 has a straight portion 62A and a bent portion 62B along the flexible substrate 11 having a straight portion 11C and a bent portion 11D, similarly to the first protection plate 61. The straight portion 62A is a portion formed in a straight line shape, and is arranged with respect to the entire section from one end 111A to the other end 111C of the reinforcement 111. The bent portions 62B are provided at both ends of the straight portion 62A, and are portions that are bent at each end and hang down downward.

[0091] Such first protection plate 61 and second protection plate 62 can sandwich and protect the flexible substrate 11 having the straight portion 11C and the bent portion 11D.

[0092] As described above, the wire harness WHE according to the sixth embodiment can reliably protect the flexible substrate 11 even when the flexible substrate 11 is bent by including the first protection plate 61 and the second protection plate 62 that sandwich and protect the flexible substrate 11 .

[0093] In addition, when the flexible substrate 11 is bent, the first protection plate 61 and the second protection plate 62 are bent in accordance with the bent shape of the flexible substrate 11 to clamp and protect the flexible substrate 11. Therefore, the wire harness WHE according to the sixth embodiment can reliably protect the flexible substrate 11.

[0094] The above examples illustrate the embodiments of the present invention, but the above embodiments are only examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other ways, and various omissions, substitutions, combinations, and changes can be made without departing from the scope of the main purpose of the invention. In addition, the specifications of various structures, shapes, etc. (structure, type, direction, form, size, length, width, thickness, height, quantity, configuration, position, material, etc.) can be appropriately changed for implementation.
