Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, in conventional wire harnesses, before being installed in the reinforcement's harness routing space, all the harnesses, depending on the required number of circuits, are bundled together in a way that conforms to the spatial shape of the harness routing space. For example, all the harnesses are bundled together with tape. In this case, for example, all the harnesses are placed on a jig plate to conform to the spatial shape of the harness routing space, and tape is wrapped around all the harnesses on the jig plate to bundle them together in a way that conforms to the spatial shape of the harness routing space. In another example, all the harnesses are divided into multiple sub-harnesses, each containing at least one harness, and these multiple sub-harnesses are first formed. Then, in this wire harness, all the sub-harnesses are bundled together with tape. In this case, all the sub-harnesses are pre-formed on a jig plate to conform to the spatial shape of the harness routing space. In this process, for sub-harnesses comprising multiple harnesses, the multiple harnesses are bundled together with tape. Then, in this wire harness, all sub-harnesses are repositioned on a jig plate to match the spatial shape of the harness routing space, and all sub-harnesses on the jig plate are bundled together by wrapping tape around them to match the spatial shape of the harness routing space. Thus, conventional wire harnesses require a wire harness manufacturing process as exemplified above, and a wire harness installation process in which the assembled wire harness is installed inside the reinforcement. Therefore, conventional wire harnesses involve numerous work processes, and from the perspective of productivity, there is room for improvement.

[0005] Therefore, the object of the present invention is to provide a method for manufacturing a wire harness and a wire harness that can improve productivity. [Means for solving the problem]

[0006] The wire harness manufacturing method according to the present invention comprises a sub-harness manufacturing step of manufacturing a plurality of sub-harnesses each comprising at least one harness, and a sub-harness installation step of installing all of the sub-harnesses in a harness routing space inside a reinforcement to which one end and the other end are fixed to a vehicle body, wherein the sub-harness manufacturing step involves manufacturing a plurality of sub-harnesses each comprising one harness or a plurality of harnesses bundled together so as not to come undone, or manufacturing at least one sub-harness each comprising one harness and a plurality of harnesses bundled together so as not to come undone, and the sub-harness installation step involves installing all of the sub-harnesses manufactured in the sub-harness manufacturing step one by one into the harness routing space.

[0007] The wire harness according to the present invention comprises a plurality of sub-harnesses, each having at least one harness, wherein the plurality of sub-harnesses are configured by comprising a plurality of sub-harnesses, each having one harness or a plurality of harnesses bundled together so as not to come undone, or by comprising at least one sub-harness, each having one harness and a plurality of harnesses bundled together so as not to come undone, and all of the sub-harnesses are installed in a harness routing space inside a reinforcement, one end of which is fixed to the vehicle body, in a manner that allows for relative displacement between them within that space. [Effects of the Invention]

[0008] In conventional wire harness manufacturing methods, after manufacturing all the sub-harnesses, all of these sub-harnesses are bundled together with an outer covering or clamp, and then this integrated set of sub-harnesses is installed in the harness routing space of the reinforcement. In contrast, the wire harness manufacturing method according to the present invention does not require the process of bundling all the sub-harnesses together with an outer covering or clamp, thus improving productivity compared to conventional wire harness manufacturing methods. Furthermore, the wire harness manufacturing method according to the present invention allows the reinforcement to be used as a jig for installing the sub-harnesses, and does not require forks or other devices for restricting the routing of the sub-harnesses erected on the jig plate, thus improving productivity compared to conventional wire harness manufacturing methods. Moreover, the wire harness according to the present invention is manufactured using this highly productive manufacturing method and does not require outer coverings or clamps to bundle all the sub-harnesses together, thus contributing to cost reduction.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, a method for manufacturing a wire harness and an embodiment of the wire harness according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited by this embodiment.

[0011] [Embodiment] A method for manufacturing a wire harness and an embodiment of the wire harness according to the present invention will be described based on FIGS. 1 to 3.

[0012] Reference numeral 1 in FIGS. 1 and 2 indicates the wire harness of this embodiment. This wire harness 1 includes a plurality of sub-harnesses 10 each including at least one harness 11 (from FIGS. 1 to 3). The harness 11 refers to an electric wire (including shielded wires, twisted wires, enameled wires, etc.) or a communication line, regardless of its type and size. In the wire harness 1, all the sub-harnesses 10 are installed in a harness routing space 20a inside a reinforcement 20 in a vehicle such as an automobile (FIGS. 1 and 2). The manufacturing method of this wire harness 1 includes a sub-harness manufacturing process for manufacturing a plurality of the sub-harnesses 10, and a sub-harness installation process for installing all the sub-harnesses 10 in the harness routing space 20a of the reinforcement 20 whose one end and the other end are fixed to the vehicle body. The sub-harness 10 is routed along the inner wall surface of the harness routing space 20a between one end and the other end of the reinforcement 20.

[0013] This wire harness 1 may be composed of the sub-harnesses 10, or may include the reinforcement 20 as one of its own constituent elements in addition to the sub-harnesses 10. The wire harness 1 illustrated here includes the reinforcement 20 as one of its own constituent elements, and can also be called a wire harness 1 with a reinforcement 20, a wire harness assembly, or a wire harness module.

[0014] The reinforcement 20 refers to vehicle body components such as instrument panel reinforcements and bumper reinforcements. Instrument panel reinforcements are support components that support the instrument panel, monitors and gauges installed in the center cluster, the dashboard, displays installed in front of the dashboard, and the steering column. The sub-harness 10 is responsible for supplying power to these components and for communication between these components and control devices. The instrument panel reinforcement is positioned between the instrument panel and the front bulkhead, extending in the vehicle width direction. For example, in the case of instrument panel reinforcements, one end and the other end in the direction of extension are fixed to the left and right A-pillars, respectively, and the fixing parts such as brackets are extended toward the dash panel or cowl inner panel and fixed to the dash panel or cowl inner panel. Bumper reinforcements are reinforcing components intended to protect the vehicle body. This bumper reinforcement is positioned inside the front and rear bumpers of the vehicle, extending in the width direction of the vehicle. The bumper reinforcement is fixed at one end and the other end in its extending direction to, for example, the side members. The sub-harness 10 is responsible for communication between, for example, sensors installed on the bumper and control devices.

[0015] Here, an instrument panel reinforcement is shown as an example of the reinforcement 20. This reinforcement 20 may be molded from a metal material or from a synthetic resin material.

[0016] This reinforcement 20 comprises a reinforcement body 21 having a harness routing space 20a and a harness insertion opening 20b for inserting the sub-harness 10 into the harness routing space 20a, which are formed between one end and the other (Figures 1 and 2).

[0017] Furthermore, the reinforcement 20 has a harness pull-out section 22 for pulling out the sub-harness 10 from the harness routing space 20a (Figures 1 and 2). This harness pull-out section 22 protrudes from the reinforcement body 21. For example, this harness pull-out section 22 has a harness pull-out space 22a that connects the harness routing space 20a with the outside of the harness routing space 20a, and a harness insertion opening 22b for inserting the sub-harness 10 into the harness pull-out space 22a (Figure 2). The harness pull-out space 22a and the harness insertion opening 22b are formed between one end and the other end of the harness pull-out section 22 in the direction of pulling out the sub-harness 10.

[0018] For example, the reinforcement body 21 is formed in a semi-cylindrical shape with a cross-section perpendicular to the vehicle width direction being a semi-circular arc shape, or in a semi-square cylindrical shape extending between one end and the other. Also, for example, the harness pull-out section 22 is formed in a semi-cylindrical shape with a cross-section perpendicular to the pull-out direction of the sub-harness 10 being a semi-circular arc shape, or in a semi-square cylindrical shape extending along the pull-out direction of the sub-harness 10. The reinforcement body 21 shown here is formed in a semi-cylindrical shape. Also, the harness pull-out section 22 shown here is formed in a semi-cylindrical shape. In this reinforcement 20, the harness insertion opening 22b of the harness pull-out section 22 is located on the same plane as the harness insertion opening 20b of the reinforcement body 21. Furthermore, in this reinforcement 20, four harness outlets 22 (first harness outlet 22A, second harness outlet 22B, third harness outlet 22C, and fourth harness outlet 22D) are provided protruding from the reinforcement body 21 (Figures 1 and 2).

[0019] For example, the reinforcement body 21 has two fixing pieces 23 formed at one end and two at the other end for fixing to the left and right A-pillars (Figures 1 and 2). The reinforcement body 21 is connected by inserting the male threaded portion (not shown) of a male threaded member through the through hole 23a of the pair of fixing pieces 23 at one end and screwing that male threaded portion into the female threaded portion of the A-pillar on the left side of the vehicle, and by inserting the male threaded portion of a male threaded member through the through hole 23a of the pair of fixing pieces 23 at the other end and screwing that male threaded portion into the female threaded portion of the A-pillar on the right side of the vehicle.

[0020] Multiple sub-harnesses 10 are configured by comprising multiple sub-harnesses 10 each having one harness 11, or multiple harnesses 11 bundled together so as not to come undone, or by comprising at least one sub-harness 10 each having one harness 11 and at least one sub-harness 10 each having multiple harnesses 11 bundled together so as not to come undone. Therefore, in the sub-harness manufacturing process, multiple sub-harnesses 10 each having one harness 11, or multiple sub-harnesses 10 each having multiple harnesses 11 bundled together so as not to come undone, are manufactured, or at least one sub-harness 10 each having one harness 11 and at least one sub-harness 10 each having multiple harnesses 11 bundled together so as not to come undone.

[0021] In the sub-harness 10, multiple harnesses 11 are bundled together, for example, with a tape 12 wrapped around them (Figure 3).

[0022] The sub-harness 10 has a main line 13 and branch lines 14 that branch off from the main line 13 (Figures 1 and 2). The sub-harness 10 may also have another branch line (hereinafter also called a "sub-branch line") 15 that further branches off from its branch line (hereinafter also called a "main branch line") 14 (Figures 1 and 2).

[0023] Furthermore, the sub-harness 10 is equipped with connectors 16 at the ends of its branch lines (main branch line) 14 and sub-branch line 15 (Figures 1 and 2). These connectors 16 may be either male or female connectors that connect to various components such as monitors and displays, or they may be intermediate connectors. A circuit board with functions such as control and wireless communication may be assembled into the sub-harness 10.

[0024] Furthermore, this sub-harness 10 may also have an exterior component (for example, a protective component such as a protector or corrugated tube) 17 attached to its branch wire (main branch wire) 14 and sub-branch wire 15 (Figures 1 and 2).

[0025] In the sub-harness manufacturing process, the sub-harness 10 is manufactured in a shape that matches the spatial shape of the harness routing space 20a so that the sub-harness 10 is aligned with the harness routing space 20a between one end and the other end of the reinforcement 20. Here, the main line 13 of the sub-harness 10 is manufactured in a shape that matches the spatial shape of the harness routing space 20a. Then, in this sub-harness manufacturing process, the branch lines (main branch lines) 14 of the sub-harness 10 are manufactured in a shape that matches the position and route of the harness outlet 22 of the reinforcement 20 and the connection position of the terminal connector 16 to the mating end. Furthermore, in this sub-harness manufacturing process, the secondary branch lines 15 of the sub-harness 10 are manufactured in a shape that matches the connection position of the terminal connector 16 to the mating end.

[0026] In this sub-harness manufacturing process, connectors 16 are connected to the ends of the branch wires (main branch wires) 14 and the sub-branch wires 15, and exterior members 17 are attached to the branch wires (main branch wires) 14 and the sub-branch wires 15 as needed.

[0027] The wire harness 1 illustrated here includes three types of sub-harnesses 10: a first sub-harness 10A, a second sub-harness 10B, and a third sub-harness 10C (Figures 1 and 2).

[0028] The first sub-harness 10A includes a main line 13, main branch lines 14 branched from the main line 13 (first main branch line 14A, second main branch line 14B, third main branch line 14C, and fourth main branch line 14D), one sub-branch line 15 branched from the first main branch line 14A and one sub-branch line 14B, and two sub-branch lines 15 branched from the third main branch line 14C (Figures 1 and 2). Connectors 16 are connected to the terminals of the first main branch line 14A, the second main branch line 14B, the third main branch line 14C, the fourth main branch line 14D, and each sub-branch line 15 in the first sub-harness 10A. Furthermore, exterior members 17 are appropriately attached to the main branch lines 14 and sub-branch lines 15 in the first sub-harness 10A.

[0029] The second sub-harness 10B has a main line 13 and main branch lines 14 (first main branch line 14A, second main branch line 14B, and third main branch line 14C) branched from the main line 13 (Figures 1 and 2). Connectors 16 are connected to each end of the first main branch line 14A, the second main branch line 14B, and the third main branch line 14C of this second sub-harness 10B.

[0030] The third sub-harness 10C has a main line 13 and main branch lines 14 (first main branch line 14A and second main branch line 14B) branched from the main line 13 (Figures 1 and 2). Connectors 16 are connected to the respective ends of the first main branch line 14A and the second main branch line 14B in this third sub-harness 10C. In addition, an outer covering member 17 is attached to the second main branch line 14B in this third sub-harness 10C.

[0031] In wire harness 1, the sub-harness 10 is installed in the harness routing space 20a and assembled to the reinforcement 20, and the reinforcement 20 is also used as a jig for assembling the sub-harness 10.

[0032] For example, the manufacturing method of this wire harness 1 includes a jig installation step in which the reinforcement 20 is installed as a jig on a base (not shown) such as a jig plate. For example, in this jig installation step, the reinforcement 20 is installed on the base with the harness insertion opening 20b facing towards the user (in other words, towards the worker).

[0033] In the sub-harness installation process, all sub-harnesses 10 manufactured in the sub-harness manufacturing process are installed one by one into the harness routing space 20a of the reinforcement 20 (Figures 1 and 2).

[0034] In this sub-harness installation process, first, the main line 13 of the first sub-harness 10A is inserted into the harness routing space 20a from the harness insertion port 22b of the reinforcement body 21, and the first main branch line 14A, the second main branch line 14B, the third main branch line 14C, and the fourth main branch line 14D of the first sub-harness 10A are inserted into the harness routing space 22a from the respective harness insertion ports 22b of the first to fourth harness outlet sections 22A-22D (Figures 1 and 2). Next, in this sub-harness installation process, the main line 13 of the second sub-harness 10B is inserted into the harness routing space 20a from the harness insertion port 22b of the reinforcement body 21, and the first main branch line 14A, the second main branch line 14B, and the third main branch line 14C of the second sub-harness 10B are inserted into the harness routing space 22a from the respective harness insertion ports 22b of the first, second, and fourth harness outlet sections 22A, 22B, and 22D (Figures 1 and 2). In this sub-harness installation process, the main line 13 of the third sub-harness 10C is inserted into the harness routing space 20a from the harness insertion port 22b of the reinforcement body 21, and the first main branch line 14A and the second main branch line 14B of the third sub-harness 10C are inserted into the harness routing space 22a from the respective harness insertion ports 22b of the second and fourth harness outlet sections 22B and 22D (Figures 1 and 2).

[0035] In the sub-harness installation process, in all steps of installing all sub-harnesses 10 (first sub-harness 10A, second sub-harness 10B, third sub-harness 10C), the main branch lines 14 (first main branch line 14A, second main branch line 14B, third main branch line 14C, and fourth main branch line 14D) and sub-branch lines 15 are pulled out from the outlets of their respective harness outlets 22 (first harness outlet 22A, second harness outlet 22B, third harness outlet 22C, and fourth harness outlet 22D) (Figure 1). Therefore, all connectors 16 are located outside the harness routing space 20a and the harness outlet space 22a.

[0036] All sub-harnesses 10 (first sub-harness 10A, second sub-harness 10B, third sub-harness 10C) are installed in the harness routing space 20a and the harness exit space 22a in a manner that allows for relative displacement between them within those spaces. However, for the main branch line 14, positional displacement at its end may be suppressed, for example, by wrapping tape around the end on the exit side of the harness exit section 22.

[0037] The wire harness 1 produced in this manner has the following advantages compared to conventional wire harnesses. For example, in the conventional wire harness manufacturing method, after manufacturing all the sub-harnesses 10, all of these sub-harnesses 10 are bundled together with an outer covering member or clamp, and these integrated sub-harnesses 10 are then installed in the harness routing space 20a and harness exit space 22a of the reinforcement 20. In contrast, the manufacturing method of the wire harness 1 of this embodiment does not require the process of bundling all the sub-harnesses 10 together with an outer covering member or clamp, thus improving productivity compared to the conventional wire harness manufacturing method. Furthermore, the manufacturing method of the wire harness 1 of this embodiment allows the reinforcement 20 to be used as a jig for installing the sub-harnesses, eliminating the need for forks or the like for routing the sub-harnesses 10 that are erected on a jig plate, thus improving productivity compared to the conventional wire harness manufacturing method. Furthermore, the wire harness 1 of this embodiment is manufactured using this highly productive manufacturing method, and since it does not require an outer covering or clamps to bundle all the sub-harnesses 10 together, it contributes to weight reduction and cost reduction.

[0038] Furthermore, since the manufacturing method of the wire harness 1 in this embodiment involves installing each sub-harness 10 one by one into the harness routing space 20a and harness exit space 22a of the reinforcement 20, it is also possible to accommodate automatic routing of the sub-harnesses 10. For example, in this manufacturing method, if the harness routing space 20a is linear or substantially linear, it becomes easy to accommodate automatic routing of the sub-harnesses 10.

[0039] Furthermore, the wire harness 1 in this embodiment is a single component integrated with the reinforcement 20, and since it can be managed as a single component in the factory, it becomes possible to reduce the number of part numbers to be managed and the amount of storage space required for parts. Therefore, the wire harness 1 in this embodiment can improve productivity.

[0040] Furthermore, the wire harness 1 of this embodiment only requires assembling this single component, which integrates the harness components and the reinforcement 20, to the vehicle body. Since both the harness components and the reinforcement 20 can be assembled at the same time, productivity can be improved. In this case, the wire harness 1 of this embodiment involves assembling the reinforcement 20, which has higher rigidity and a more stable shape compared to the harness components, to the vehicle body, thus enabling automated assembly to the vehicle body.

[0041] [Example 1] Reference numeral 2 in Figure 4 indicates the wire harness of this modified example. The wire harness 2 of this modified example corresponds to the wire harness 1 of the previously described embodiment, in which the reinforcement 20 is replaced with the reinforcement 120 described below.

[0042] The reinforcement 120 in this modified example comprises a reinforcement body 121 having a harness routing space 120a and a harness insertion opening 120b for inserting the sub-harness 10 into the harness routing space 120a, which are formed between one end and the other. The reinforcement 120 in this modified example also has a harness pull-out section 122 for pulling the sub-harness 10 out of the harness routing space 120a. This reinforcement 120 has a modified shape of the harness routing space 120a compared to the reinforcement 20 of the embodiment. The harness pull-out section 122 is, for example, similar to the harness pull-out section 22 of the embodiment and is projected from the reinforcement body 121.

[0043] In this modified example, the harness routing space 120a has multiple layers of harness housing grooves (first harness housing groove 123a, second harness housing groove 123b, and third harness housing groove 123c) extending from the bottom towards the harness insertion opening 120b. The width of these first harness housing grooves 123a, second harness housing groove 123b, and third harness housing groove 123c narrows towards the bottom and extends between one end and the other end of the reinforcement body 121. In the harness routing space 120a, the first harness housing groove 123a, the lowest layer at the bottom, has the narrowest groove width, the second harness housing groove 123b, the middle layer, has a wider groove width than the first harness housing groove 123a, and the third harness housing groove 123c, the uppermost layer, has a wider groove width than the second harness housing groove 123b.

[0044] In the harness routing space 120a of this modified example, one sub-harness 10 may be accommodated in each harness housing groove (first harness housing groove 123a, second harness housing groove 123b, and third harness housing groove 123c). In this case, it is desirable that each of the multiple sub-harnesses 10 be formed with a shape that matches the groove width and groove depth of each harness housing groove. For example, it is desirable that the sub-harness 10 be sandwiched between a pair of side walls located in the groove width direction within the harness housing groove. As a result, in the reinforcement 120 of this modified example, the sub-harness 10 can be held within the harness housing groove, so it is not necessary to prepare a holding member or the like to hold the sub-harness 10 in the harness routing space 120a. Furthermore, in the reinforcement 120 of this modified example, entanglement between the sub-harnesses 10 can be suppressed.

[0045] In addition, in the harness routing space 120a of this modified example, multiple sub-harnesses 10 may be housed in harness housing grooves with wider groove widths (for example, the third harness housing groove 123c).

[0046] In this modified example, the reinforcement 120 has multiple harness housing grooves (first harness housing groove 123a, second harness housing groove 123b, and third harness housing groove 123c) formed inside the reinforcement body 121, so it is desirable to mold it from a synthetic resin material.

[0047] Thus, the manufacturing method of the wire harness 2 and the wire harness 2 of this modified example not only provide the same effects as the manufacturing method of the wire harness 1 and the wire harness 1 of the embodiment, but also provide a function to hold the sub-harness 10 in the harness routing space 120a and a function to prevent entanglement.

[0048] The harness housing groove may be provided in the harness routing space (not shown) inside the harness pull-out section 122.

[0049] [Differentiation 2] Reference numeral 3 in Figure 5 indicates the wire harness of this modified example. The wire harness 3 of this modified example corresponds to the wire harness 2 of the previously described modified example 1, in which the reinforcement 120 is replaced with the reinforcement 220 described below.

[0050] In the first modified example, the reinforcement 120 holds the sub-harness 10 in the harness routing space 120a by clamping it between a pair of side walls within the harness housing grooves (first harness housing groove 123a, second harness housing groove 123b, and third harness housing groove 123c). The reinforcement 220 in this modified example further enhances the sub-harness 10 holding function.

[0051] The reinforcement 220 of this modified example includes a reinforcement body 221 having a harness routing space 220a and a harness insertion opening 220b for inserting the sub-harness 10 into the harness routing space 220a, which are formed between one end and the other. The reinforcement 220 of this modified example also has a harness pull-out section 222 for pulling the sub-harness 10 out of the harness routing space 220a. The harness routing space 220a of this modified example is provided with harness housing grooves (first harness housing groove 223a, second harness housing groove 223b, and third harness housing groove 223c) similar to the harness routing space 120a of Modified Example 1. Furthermore, the harness pull-out section 222 is projected from the reinforcement body 221, for example, in the same way as the harness pull-out section 22 of the embodiment, as in Modified Example 1.

[0052] In this modified wire harness 3, a harness locking member 230 that locks the movement of the sub-harness 10 toward the harness insertion port 220b is assembled in the harness routing space 220a.

[0053] The harness locking member 230 has a harness locking portion 231 for locking the sub-harness 10. This harness locking portion 231 is a flexible spring portion that extends in the groove width direction of the harness housing grooves (first harness housing groove 223a, second harness housing groove 223b, and third harness housing groove 223c).

[0054] The harness locking member 230 has projections 232 at one end and the other end of the harness locking portion 231 in the extending direction, for securing the harness locking portion 231 within the harness routing space 220a. These projections 232 are formed, for example, in a polygonal shape (in this case, a triangular prism shape) with the extending direction of the harness housing groove as their axial direction.

[0055] Each side wall of the harness housing groove (first harness housing groove 223a, second harness housing groove 223b, and third harness housing groove 223c) has a projection housing groove 224 formed therein for fitting and holding the projection 232. This projection housing groove 224 is provided for each harness housing groove.

[0056] In the example shown in the figure, the respective projections 232 of the harness locking member 230 are fitted into the pair of projection housing grooves 224 in the second harness housing groove 223b, thereby locking the first sub-harness 10A and the second sub-harness 10B, which are housed in the first harness housing groove 223a and the second harness housing groove 223b, to the harness locking portion 231.

[0057] Here, the harness locking member 230 may be provided with different lengths of harness locking portion 231 for each harness housing groove. Also, since the harness locking portion 231 of the harness locking member 230 is flexible, it may be shared among multiple layers of harness housing grooves according to the difference in groove width between adjacent layers of harness housing grooves.

[0058] In this modified wire harness 3, the combination of the harness locking member 230 and the pair of projection-receiving grooves 224 may be arranged at multiple locations along the routing path of the sub-harness 10. Alternatively, in this modified wire harness 3, the harness locking member 230 and the projection-receiving grooves 224 may be extended along the routing path of the sub-harness 10 between one end and the other end of the reinforcement body 221, and the harness locking member 230 may be used as a cover to cover the sub-harness 10 from the harness insertion opening 220b side.

[0059] Thus, the manufacturing method of the wire harness 3 and the wire harness 3 of this modified example not only provide the same effects as the manufacturing method of the wire harness 2 and the wire harness 2 of Modified Example 1, but also enhance the function of holding the sub-harness 10 within the harness routing space 220a. Furthermore, the manufacturing method of the wire harness 3 and the wire harness 3 of this modified example can hold the sub-harness 10 within the harness routing space 220a without having to clamp the sub-harness 10 between the pair of side walls of the harness housing groove, as is the case with the wire harness 2 of Modified Example 1.

[0060] Furthermore, the harness locking member 230 and the projection housing groove 224 may be provided in the harness routing space (not shown) inside the harness pull-out section 222.

[0061] [Difference 3] Reference numeral 4 in Figures 6 and 7 indicates the wire harness of this modified example. The wire harness 4 of this modified example corresponds to the wire harness 1 of the previously described embodiment, in which the reinforcement 20 is replaced with the reinforcement 320 described below.

[0062] The reinforcement 320 of this modified example comprises a reinforcement body 321 having a harness routing space 320a and a harness insertion opening 320b for inserting the sub-harness 10 into the harness routing space 320a formed between one end and the other, and a cover 322 that is assembled and fixed to the reinforcement body 321 to cover all the sub-harnesses 10 and close the harness insertion opening 320b (Figures 6 and 7). The reinforcement body 321 and the cover 322 are assembled together in the completed assembly position to form a cylindrical shape.

[0063] The reinforcement body 321 and cover 322 shown here are formed in a semi-cylindrical shape with a cross-section perpendicular to the vehicle width direction being a semi-circular arc. The reinforcement body 321 and cover 322 come into contact with each other in the assembled position to form a cylindrical shape. The reinforcement body 321 and cover 322 are fixed to each other in the assembled position, for example, by screw fastening.

[0064] Furthermore, the reinforcement 320 of this modified example has a harness pull-out section 320c formed for pulling out the sub-harness 10 from the harness routing space 320a (Figures 6 and 7). This harness pull-out section 320c has a harness pull-out space 320d that connects the harness routing space 320a with the outside of the harness routing space 320a, and a harness insertion opening 320e for inserting the sub-harness 10 into the harness pull-out space 320d (Figure 7). The harness pull-out space 320d and the harness insertion opening 320e are formed between one end and the other end of the harness pull-out section 320c in the direction of pulling out the sub-harness 10.

[0065] The harness lead-out portion 320c is formed in a cylindrical or semi-cylindrical shape with the direction of lead-out of the sub-harness 10 as its axial direction. The harness lead-out portion 320c shown here is formed in a cylindrical shape with the direction of lead-out of the sub-harness 10 as its axial direction. For example, this harness lead-out portion 320c has a first sub-displacement lead-out portion 323 protruding from the reinforcement body 321 and a second sub-displacement lead-out portion 324 protruding from the cover 322 (Figures 6 and 7). The first sub-displacement lead-out portion 323 and the second sub-displacement lead-out portion 324 are formed in a semi-cylindrical shape with a cross-section perpendicular to the direction of lead-out of the sub-harness 10 being a semi-circular arc shape. The first sub-displacement lead-out portion 323 and the second sub-displacement lead-out portion 324 are brought into contact with each other to form a cylindrical shape. In the harness pull-out section 320c, a harness pull-out space 320d and a harness insertion opening 320e are provided in the first branch pull-out section 323. In the reinforcement 320, four of these harness pull-out sections 320c are provided.

[0066] The reinforcement 320 shown here comprises a first reinforcement member 320A having a reinforcement body 321 and a first sub-reduced protrusion 323, and a second reinforcement member 320B having a cover 322 and a second sub-reduced protrusion 324 (Figures 6 and 7). In this reinforcement 320, when the first reinforcement member 320A and the second reinforcement member 320B are assembled to their final position, the reinforcement body 321 and the cover 322 form a cylindrical shape, and the paired first sub-reduced protrusion 323 and second sub-reduced protrusion 324 also form a cylindrical shape. The first reinforcement member 320A in this example is molded to have the same shape as the reinforcement 20 of the embodiment. Therefore, the first reinforcement member 320A has two fixing pieces 325 formed at one end and the other end of the reinforcement body 321, similar to the fixing pieces 23 in the embodiment, for fixing to the left and right A-pillars (Figures 6 and 7).

[0067] The manufacturing method of the wire harness 4 in this modified example includes a cover assembly step in which the cover 322 is attached to the reinforcement body 321 after the sub-harness installation step is completed. For example, in the sub-harness installation step of this modified example, all sub-harnesses 10 (first sub-harness 10A, second sub-harness 10B, third sub-harness 10C) are inserted into the harness routing space 320a and the harness pulling-out space 320d from the harness insertion port 320b of the reinforcement body 321 and the harness insertion port 320e of the first branching outlet 323.

[0068] In the cover assembly process, the cover 322 is assembled to the reinforcement body 321, and this cover 322 covers all of the sub-harnesses 10 and closes the harness insertion openings 320b and 320e.

[0069] Thus, the manufacturing method of the wire harness 4 and the wire harness 4 of this modified example not only provide the same effects as the manufacturing method of the wire harness 1 and the wire harness 1 of the embodiment, but also allow the sub-harness 10 to be secured in the harness routing space 320a and the harness exit space 320d by the cover 322. Therefore, the wire harness 4 of this modified example does not require a harness housing groove that has a function of holding the sub-harness 10, as in the wire harnesses 2 and 3 of modified examples 1 and 2, nor does it require a harness locking member 230, as in the wire harness 3 of modified example 2.

[0070] Furthermore, in this modified example, the manufacturing method of the wire harness 4 and the wire harness 4 cover the root ends of the main line 13 and main branch lines 14 (first main branch line 14A, second main branch line 14B, third main branch line 14C, and fourth main branch line 14D) with the reinforcement body 321 and cover 322, so there is no need to assemble protective members such as protectors on the root ends of the main line 13 and main branch lines 14. In other words, in this modified example, the wire harness 4 can utilize the reinforcement 320 as a protective member on the root ends of the main line 13 and main branch lines 14. Therefore, the manufacturing method of the wire harness 4 and the wire harness 4 in this modified example can reduce costs while improving productivity.

[0071] Furthermore, in this modified example, the wire harness 4 has the main line 13 and the main branch line 14 covered with reinforcement 320 at their bases, which reduces the number of visual inspection items and improves the appearance.

[0072] [Differentiation Example 4] Reference numeral 5 in Figure 8 indicates the wire harness of this modified example. The wire harness 5 of this modified example corresponds to the wire harness 1 of the embodiment described above, in which the sub-harness 10 is replaced with the sub-harness 410 described below, and the reinforcement 20 is replaced with the reinforcement 420 described below.

[0073] In this modified example, the sub-harness 410, when the sub-harness 10 of the embodiment is equipped with multiple harnesses 11, restricts the arrangement of the multiple harnesses 11 as follows.

[0074] In this modified example, the sub-harness 410, when comprising multiple harnesses 11, is formed in a planar shape by arranging the multiple harnesses 11 in a direction perpendicular to the axis and bundling them together, or / or in a planar shape by dividing the multiple harnesses 11 into multiple layers, arranging each layer perpendicular to the axis, and then stacking each layer together (Figure 8). Therefore, in the manufacturing process of the sub-harness in this modified example, a sub-harness 410 in a planar shape by arranging the multiple harnesses 11 in a direction perpendicular to the axis and bundling them together, or / or in a planar shape by dividing the multiple harnesses 11 into multiple layers, arranging each layer perpendicular to the axis, and then stacking each layer together, is manufactured.

[0075] For example, in the sub-harness manufacturing process, one end of each of the two threads 412 is tied together, one thread 412 is passed over the first harness 11, and the other thread 412 is passed under the first harness 11. Subsequently, in the sub-harness manufacturing process, one thread 412 is passed under the second harness 11, and the other thread 412 is passed over the second harness 11, one thread 412 is passed over the third harness 11, and the other thread 412 is passed under the third harness 11. In the sub-harness manufacturing process, this is repeated for all harnesses 11, and the other ends of the two threads 412 that have passed over the top and bottom of the last harness 11 are tied together. In this way, a planar sub-harness 410 is manufactured using the two threads 412 (Figure 9).

[0076] Furthermore, for example, in the sub-harness manufacturing process, all of the harnesses 11, one or more layers, are placed in a mold, and the liquid synthetic resin material poured into the mold is cured. In this way, the sub-harness manufacturing process produces a planar sub-harness 410 in which all of the harnesses 11 are held in the cured mold resin 413 (Figure 10).

[0077] Furthermore, for example, in the sub-harness manufacturing process, a planar sub-harness 410 (Figure 11) is manufactured by gluing or welding all of one layer of harnesses 11 onto one sheet member 414. Alternatively, in the sub-harness manufacturing process, all of the first layer of harnesses 11 is glued or welding onto the first sheet member 414, and then the second sheet member 414 is glued or welding onto all of the first layer of harnesses 11. In this sub-harness manufacturing process, all of the second layer of harnesses 11 is glued or welding onto the second sheet member 414, and this process may be repeated for the number of layers.

[0078] Next, the reinforcement 420 of this modified example includes a reinforcement body 421 having a harness routing space 420a and a harness insertion opening 420b for inserting a sub-harness 410 into the harness routing space 420a, which are formed between one end and the other (Figure 8). This reinforcement 420 may further include a cover 422 that is assembled and fixed to the reinforcement body 421 to cover all the sub-harnesses 410 and close the harness insertion opening 420b (Figure 8). The reinforcement 420 shown here includes both the reinforcement body 421 and the cover 422.

[0079] In this reinforcement 420, for example, a first sub-sub In the reinforcement 420, when the first reinforcement member 420A and the second reinforcement member 420B are in the assembled position, a cylindrical harness pull-out portion 420c is formed by bringing the first and second discounted pull-out portions 423 and 424 into contact (Figure 8), and the sub-harness 410 of the harness routing space 420a is pulled out from this harness pull-out portion 420c.

[0080] In this modified example, the harness routing space 420a has at least one plane extending between one end and the other end of the reinforcement body 421 in the reinforcement 420, which serves as the mounting surface 425 for the sub-harness 410 (Figure 8). This mounting surface 425 is the bottom surface of the harness routing space 420a, which is positioned opposite the harness insertion opening 420b with the harness routing space 420a in between. For example, in this modified example, the reinforcement body 421 and the cover 422 are formed in a divided shape along the vehicle width direction such that when they are brought into contact with each other in the assembled position, their cross-section perpendicular to the vehicle width direction forms a rectangular tube shape. As a result, in the reinforcement body 421, the bottom surface is formed as the mounting surface 425 having at least one plane.

[0081] In the sub-harness installation process of this modified example, multiple planar sub-harnesses 410 are stacked one by one on the installation surface 425 parallel to the plane of the harness routing space 420a. As a result, the multiple planar sub-harnesses 410 are stacked one by one parallel to the plane of the harness routing space 420a (Figure 8).

[0082] Specifically, for example, the mounting surface 425 is formed by a single plane (mounting surface 425A) extending between one end and the other end of the reinforcement body 421 in the reinforcement 420 (Figure 12). In the sub-harness manufacturing process, a sub-harness 410 is manufactured in a planar form in which multiple harnesses 11 are arranged on the same plane and bundled together, or / or in a planar form in which multiple harnesses 11 are divided into multiple layers, each layer is arranged on the same plane, and each layer is stacked and bundled together, in accordance with the shape of the mounting surface 425A. Therefore, a sub-harness 410 comprising multiple harnesses 11 is formed in a planar form in which multiple harnesses 11 are arranged on the same plane and bundled together, or / or in a planar form in which multiple harnesses 11 are divided into multiple layers, each layer is arranged on the same plane, and each layer is stacked and bundled together, in accordance with the shape of the mounting surface 425A.

[0083] Furthermore, for example, the mounting surface 425 is formed by multiple planes 425a, 425b, 425c, 425d, and 425e arranged one by one, intersecting each other between one end and the other end of the reinforcement body 421 in the reinforcement 420 (mounting surface 425B) (Figure 13). In the sub-harness manufacturing process, a sub-harness 410 is manufactured in a planar form, with multiple planar sections 410a, 410b, 410c, 410d, and 410e provided parallel to each of the planes 425a, 425b, 425c, 425d, and 425e of the mounting surface 425B.

[0084] Thus, the manufacturing method of the wire harness 5 and the wire harness 5 of this modified example not only provide the same effects as the manufacturing method of the wire harness 1 and the wire harness 1 of the embodiment, and the manufacturing method of the wire harness 4 and the wire harness 4 of the modified example 3, but also allow for a reduction in size in the stacking direction by smoothing the installation surface 425 (425A, 425B) and stacking the sub-harness 410 in a planar form parallel to the plane of the installation surface 425.

[0085] [Difference 5]

[0086] Reference numeral 6 in Figures 14 and 15 indicates the wire harness of this modified example. The wire harness 6 of this modified example corresponds to the wire harness 1 of the previously described embodiment, which is equipped with at least one of the sub-harness 10 of this embodiment and the planar sub-harness 410 of the modified example 4 described above, and the reinforcement 20 is replaced with the reinforcement 520 described below.

[0087] The reinforcement 520 in this modified example includes a reinforcement body 521 having a harness routing space 520a and a harness insertion opening 520b for inserting sub-harnesses 10,410 into the harness routing space 520a, formed between one end and the other (Figures 14 and 15). This reinforcement 520 may further include a cover 522 that is assembled and fixed to the reinforcement body 521 to cover all sub-harnesses 10,410 and close the harness insertion opening 520b (Figure 14). The reinforcement 520 shown here includes both the reinforcement body 521 and the cover 522.

[0088] The reinforcement body 521 shown here has a harness outlet 523 for pulling out the sub-harnesses 10,410 from the harness routing space 520a (Figures 14 and 15). In addition, this reinforcement body 521 has a pair of fixing pieces 524 formed at one end and the other end, similar to the reinforcement body 21 of the embodiment (Figure 14).

[0089] In this modified example, the harness routing space 520a has a plurality of partition walls 525 spaced apart from each other, extending between one end and the other end of the reinforcement body 521 (Figures 14 and 15). The reinforcement body 521 shown here has five partition walls 525. The reinforcement body 521 has one harness outlet 523 on the outside of the partition walls 525 at both ends, and one harness outlet 523 is provided between two adjacent partition walls 525 at two locations.

[0090] Each of the multiple partition walls 525 has a guide groove 526 formed therein to form a group of guide grooves 526Gr for guiding the sub-harnesses 10,410 routed between one end and the other end of the reinforcement body 521 (Figures 14 and 15). In the group of guide grooves 526Gr, each guide groove 526 is arranged in a row between one end and the other end of the reinforcement body 521.

[0091] The guide groove group 526Gr is composed of multiple guide grooves 526 formed with the same groove shape. The sub-harness 10,410 is formed to match the groove shape of each guide groove 526 in the guide groove group 526Gr so that it can be positioned within the groove of that guide groove 526. Therefore, in the sub-harness manufacturing process of this modified example, a sub-harness 10,410 with such a shape is manufactured.

[0092] In this modified example, the harness routing space 520a is provided with one guide groove group 526Gr, which consists of the guide grooves 526 (Figures 14 and 15). Therefore, all sub-harnesses 10,410 are housed in their respective guide grooves 526 of this guide groove group 526Gr. For example, in the sub-harness installation process, all sub-harnesses 10,410 manufactured in the sub-harness manufacturing process are installed one by one into their respective guide grooves 526Gr of the guide groove group 526Gr.

[0093] In this modified example, guide grooves 526 are formed in a rectangular shape with a straight bottom surface, and a planar sub-harness 410, in which multiple harnesses 11 are arranged along the straight bottom surface, is housed in each guide groove 526 (Figure 16). Here, two layers of the planar sub-harness 410 are housed, and three sub-harnesses 10 are placed on top of them.

[0094] The manufacturing method of the wire harness 6 and the wire harness 6 of this modified example can achieve the same effects as the manufacturing method of the wire harness 1 and the wire harness 1 of the embodiment by providing the guide groove group 526Gr in the harness routing space 520a in this manner.

[0095] [Modification 6]

[0096] Reference numeral 7 in Figures 17 and 18 indicates the wire harness of this modified example. The wire harness 7 of this modified example corresponds to the wire harness 6 of the previously described modified example 5, in which the reinforcement 520 is replaced with the reinforcement 620 described below.

[0097] The reinforcement 620 in this modified example comprises a reinforcement body 621 having a harness routing space 620a and a harness insertion opening 620b for inserting sub-harnesses 10,410 into the harness routing space 620a, which are formed between one end and the other (Figures 17 and 18). This reinforcement 620 may further include a cover 622 that is assembled and fixed to the reinforcement body 621 to cover all sub-harnesses 10,410 and close the harness insertion opening 620b (Figure 17). The reinforcement 620 shown here comprises both the reinforcement body 621 and the cover 622.

[0098] The reinforcement body 621 shown here has a harness outlet 623 for pulling out the sub-harnesses 10,410 from the harness routing space 620a (Figures 17 and 18). In addition, this reinforcement body 621 has a pair of fixing pieces 624 formed at one end and the other end, similar to the reinforcement body 521 of the embodiment (Figure 17).

[0099] The harness routing space 620a in this modified example has multiple partition walls 625, each having a guide groove formed for forming a group of guide grooves, similar to the harness routing space 520a in Modified Example 5 (Figures 17 and 18). However, unlike the harness routing space 520a in Modified Example 5, the harness routing space 620a in this modified example has multiple groups of guide grooves. All sub-harnesses 10,410 are accommodated at least one per group of guide grooves in each group of guide grooves. Therefore, in the sub-harness installation process, all sub-harnesses 10,410 are installed at least one per group of guide grooves in each group of guide grooves.

[0100] In this example, a first guide groove group 626Gr is provided, consisting of a plurality of first guide grooves 626 arranged between one end and the other end of the reinforcement body 621, and a second guide groove group 627Gr is provided, consisting of a plurality of second guide grooves 627 arranged between one end and the other end of the reinforcement body 621 (Figures 17 and 18).

[0101] Each partition wall 625 is provided with a first guide groove 626 whose bottom surface is formed in a straight rectangular shape, and a second guide groove 627 whose bottom surface is formed in an arc shape (Figure 18). The first guide groove 626 accommodates a sub-harness 410 in a planar form in which multiple harnesses 11 are arranged along the straight line of the bottom surface. On the other hand, the second guide groove 627 accommodates a sub-harness 10 in which multiple harnesses 11 are bundled together in a cylindrical shape.

[0102] For example, in the wire harness 7 of this modified example, one planar sub-harness 410 is housed in each first guide groove 626 of the first guide groove group 626Gr, and one cylindrical sub-harness 10 is housed in each second guide groove 627 of the second guide groove group 627Gr (Figure 19). In addition, in the wire harness 7 of this modified example, multiple (in this case, four) planar sub-harnesses 410 are housed in layers in each first guide groove 626 of the first guide groove group 626Gr, and one cylindrical sub-harness 10 is housed in each second guide groove 627 of the second guide groove group 627Gr (in this case, six) (Figure 20).

[0103] The manufacturing method of the wire harness 7 and the wire harness 7 of this modified example can achieve the same effects as the manufacturing method of the wire harness 6 and the wire harness 6 of Modified Example 5.

[0104] Furthermore, the manufacturing method and wire harness 7 of this modified example may accommodate wiring materials other than the sub-harnesses 10 and 410 routed in the harness routing space 620a. For example, the manufacturing method and wire harness 7 of this modified example can accommodate the sub-harnesses 10 and 410 in each guide groove of a certain group of guide grooves, and wiring materials other than the sub-harnesses 10 and 410 in each guide groove of a different group of guide grooves, thus allowing for the classification of wiring materials to be accommodated for each group of guide grooves.
