Summary of Invention

Problems to be Solved by the Invention

[0004] By the way, in a wire harness that routes the harness main body in the inner space of the reinforcement, the harness main body can be protected by such an arrangement. However, in the case where the harness main body is routed along the outer wall surface of the reinforcement, the conventional wire harness requires that the harness main body be covered with a protective member such as a protector and then assembled to the outer wall surface of the reinforcement.

[0005] Accordingly, an object of the present invention is to provide a wire harness capable of easily protecting a harness main body on the outer wall surface of a reinforcement.

Means for Solving the Problems

[Effects of the Invention]

[0009] An embodiment of the wire harness according to the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention.

[0010] [Embodiment] One embodiment of the wire harness according to the present invention will be described with reference to Figures 1 to 10.

[0011] Reference numeral 1 in Fig. 1 and Fig. 2 indicates the wire harness of the present embodiment. This wire harness 1 includes a harness main body 10, and a reinforcement 20 whose one end and the other end are fixed to a vehicle body of a vehicle such as an automobile. The harness main body 10 is routed along the reinforcement 20 and assembled to the reinforcement 20. Therefore, this wire harness 1 can also be referred to as the wire harness 1 with the reinforcement 20, a wire harness assembly, or a wire harness module.

[0012] The harness main body 10 includes a plurality of harnesses 11 (Fig. 3 and Fig. 4). The harnesses 11 refer to electric wires (including shielded wires, twisted wires, enameled wires, etc.) and communication lines, and there is no limitation on their type or size.

[0013] For example, the harness main body 10 is obtained by winding a tape around a plurality of harnesses 11 bundled in a cylindrical shape to integrate them (Fig. 3), or by preparing a plurality of sub-harnesses each formed by bundling a plurality of harnesses 11 together, and winding a tape around the plurality of sub-harnesses bundled in a cylindrical shape to integrate them (not shown). Although the illustration of the tape is omitted in Fig. 1 and Fig. 2, such a cylindrical harness main body 10 is illustrated.

[0014] Further, the harness main body 10 may be formed by arranging a plurality of harnesses 11 flat in a direction perpendicular to the axis and bundling them together while maintaining their planar form (Fig. 4). This harness main body 10 may be formed by bundling the plurality of harnesses 11 in the planar form together with a thread or the like, or may be formed by pouring a liquid synthetic resin into a mold in which the plurality of harnesses 11 in the planar form are placed and solidifying the resin. Further, the harness main body 10 may be formed by adhering the plurality of harnesses 11 in the planar form onto one sheet using an adhesive or a welding technique, or may be formed by sandwiching the plurality of harnesses 11 in the planar form between two sheets and bonding or welding the two sheets together with an adhesive.

[0015] The harness body 10 has a main line 12 and branch lines 13 branched from the main line 12 (Figures 1 and 2). The harness body 10 may also have another branch line (hereinafter also called a "sub-branch line") 14 further branched from its branch line (hereinafter also called a "main branch line") 13 (Figures 1 and 2). The harness body 10 shown here has multiple branch lines (main branch lines) 13.

[0016] Furthermore, the harness body 10 is equipped with connectors 15 at the ends of its branch lines (main branch line) 13 and sub-branch line 14 (Figures 1 and 2). These connectors 15 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 harness body 10.

[0017] 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 harness body 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 harness body 10 is responsible for communication between, for example, sensors installed on the bumper and control devices.

[0018] This reinforcement 20 is made of synthetic resin, molded from synthetic resin material. Here, an instrument panel reinforcement is shown as an example of reinforcement 20.

[0019] The reinforcement 20 includes a reinforcement body 21 extending from one end to the other (Figures 1 and 2). The harness body 10 is routed along the outer wall surface 21a of the reinforcement body 21 (Figures 1 and 2). This outer wall surface 21a may be the upper wall surface of the reinforcement body 21 when mounted in a vehicle, or it may be the side wall surface of the reinforcement body 21 when mounted in a vehicle. Furthermore, this outer wall surface 21a may be the lower wall surface of the reinforcement body 21 when mounted in a vehicle, provided that a cover member 26, described later, is attached to it.

[0020] A harness routing space 22a is provided on the outer wall surface 21a of the reinforcement body 21, where the harness body 10 is installed (Figures 1 and 2). The main line 12 of the harness body 10 is installed in this harness routing space 22a. The main line 12 is routed within this harness routing space 22a from one end to the other end of the reinforcement body 21, and is pulled out from the harness routing space 22a from one end and the other end. The harness routing space 22a is formed with one end and the other end opening in the direction from which the main line 12 is pulled out.

[0021] The harness routing space 22a is formed between a pair of opposing wall surfaces 23a that are spaced apart on the outer wall surface 21a of the reinforcement body 21 (Figures 1 and 2). This pair of opposing wall surfaces 23a each extend in the direction of extension of the reinforcement body 21. An opening is formed between this pair of opposing wall surfaces 23a, along the direction of extension of the reinforcement body 21. This opening is a harness insertion port 22b for inserting the main wire 12 into the harness routing space 22a (Figures 1 and 2). The harness insertion port 22b shown here is formed between the tip portions of the pair of vertical walls 23 described below, which protrude from the outer wall surface 21a of the reinforcement body 21.

[0022] At least one of the pair of opposing wall surfaces 23a is the wall surface of a plate-shaped vertical wall 23 that protrudes from the outer wall surface 21a as part of the reinforcement body 21. In this example, a pair of vertical walls 23 protrude from the flat outer wall surface 21a of the reinforcement body 21 at the same height and spaced apart from each other (Figures 1 and 2). Therefore, the harness routing space 22a shown here is formed between the opposing wall surfaces 23a of the pair of vertical walls 23. However, if the outer wall surface 21a has a wall surface that can be used as one of the opposing wall surfaces 23a, the harness routing space 22a may also be formed between one of the opposing wall surfaces 23a and the other opposing wall surface 23a of the vertical wall 23 by providing a plate-shaped vertical wall 23 on the outer wall surface 21a that is spaced apart from and opposite to this one opposing wall surface 23a (not shown).

[0023] The reinforcement body 21 has fixing pieces formed at one end and the other end for fixing to the left and right A-pillars (not shown). The male threaded portion (not shown) of the male threaded member is inserted through the through hole of the fixing piece at one end of the reinforcement body 21 and screwed into the female threaded portion of the A-pillar on the left side of the vehicle, and the male threaded portion of the male threaded member is inserted through the through holes of the pair of fixing pieces at the other end and screwed into the female threaded portion of the A-pillar on the right side of the vehicle.

[0024] In this embodiment, the wire harness 1 restricts the path of the harness body 10 and suppresses interference between the harness body 10 and surrounding components by using a harness routing space 22a (i.e., a pair of vertical walls 23) provided on the outer wall surface 21a of the reinforcement body 21. Therefore, the wire harness 1 of this embodiment can protect the harness body 10 on the outer wall surface 21a of the reinforcement body 21 without using protective members such as protectors or corrugated tubes as in the past. Consequently, the wire harness 1 of this embodiment can prevent a deterioration in the quality of the harness body 10.

[0025] Here, the main wire 12 is sufficiently protected even if it is not protected by the vertical wall 23, as long as there are no surrounding components nearby that may cause interference. Therefore, the vertical wall 23 may be provided with an opening 23b, such as a notch, in the part facing such a part (Figure 5). As a result, the wire harness 1 of this embodiment can be made lighter overall by reducing the weight of the vertical wall 23.

[0026] Furthermore, in the wire harness 1 of this embodiment, since the reinforcement body 21 is made of synthetic resin, the vertical wall 23 can be molded together with the reinforcement body 21 during the molding process. Therefore, in the wire harness 1 of this embodiment, the harness routing space 22a can be formed inexpensively on the outer wall surface 21a of the reinforcement body 21. Moreover, since the wire harness 1 of this embodiment does not require protective members such as protectors or corrugated tubes as in the conventional method, it is possible to reduce costs by reducing the number of parts.

[0027] Furthermore, in this embodiment, if the positional displacement of the harness body 10 within the harness routing space 22a can be suppressed, for example, by sandwiching the harness body 10 between a pair of closely spaced opposing wall surfaces 23a, then the wire harness 1 does not require a holding member such as a clamp to hold the harness body 10 in the reinforcement body 21 within the harness routing space 22a. As a result, the wire harness 1 of this embodiment can improve the ease of assembly when assembling the harness body 10 to the reinforcement body 21.

[0028] Incidentally, the vertical wall 23 is provided with openings that divide the reinforcement body 21 into one side and the other side in the direction of extension, corresponding to the position of the branch lines (main branch lines) 13. These openings are branch line outlets 22c that bring out the branch lines (main branch lines) 13, which have been branched in the harness routing space 22a, to the outside of the harness routing space 22a (Figures 1 and 2). For example, the vertical wall 23 has branch line outlets 22c equal to the number of branch lines (main branch lines) 13.

[0029] The outer wall surface 21a of the reinforcement body 21 shown here is provided with a harness outlet 25 that connects the harness routing space 22a with the outside of the harness routing space 22a via its branch wire outlet 22c (Figures 1 and 2). This harness outlet 25 is formed of a pair of plate-shaped vertical walls that protrude from the outer wall surface 21a of the reinforcement body 21 at a distance from each other and at the same height. This harness outlet 25 is provided with a harness outlet space 25a that connects the harness routing space 22a with the outside of the harness routing space 22a via the branch wire outlet 22c, and a harness insertion opening 25b for inserting the branch wire (main branch wire) 13 into this harness outlet space 25a.

[0030] In the reinforcement 20, the harness lead-out portion 25 is also formed as part of the reinforcement body 21. Therefore, in this embodiment, the wire harness 1 can be formed together with the harness lead-out portion 25 during the molding process of the reinforcement body 21.

[0031] In this case, the wire harness 1 may have peripheral components positioned on the harness insertion port 22b, 25b side. In this case, the wire harness 1 requires measures to avoid interference between the peripheral components on the harness insertion port 22b, 25b side and the harness body 10. Therefore, the reinforcement 20 in this case is equipped with a cover member 26 that closes the harness insertion port 22b, 25b to avoid such interference (Figures 6 and 7).

[0032] The cover member 26 is molded from a synthetic resin material. This cover member 26 is held in place by a locking mechanism, such as a claw, at the respective ends of the reinforcing body 21 that protrude from the outer wall surface 21a of the pair of vertical walls 23 (not shown).

[0033] In this embodiment, the wire harness 1 can enhance the protective function of the harness body 10 by providing such a cover member 26 on the reinforcement 20. Furthermore, since this wire harness 1 only requires housing the harness body 10 in the harness routing space 22a and the harness exit space 25a and assembling the cover member 26 to the vertical wall 23, the assembly workability can be improved.

[0034] Furthermore, the wire harness 1 of this embodiment may consist of multiple cylindrical or planar harness bodies 10, and by assembling the cover member 26 to the reinforcement body 21, the multiple harness bodies 10 can be secured to the harness routing space 22a or harness exit space 25a without having to bundle them together with tape or the like (Figures 8 and 9).

[0035] Furthermore, in the harness body 10, branch lines (main branch lines) 13 are branched from the main line 12 in a direction different from that of the vertical wall 23. For example, when branching a branch line (main branch line) 13 towards the harness insertion opening 22b, the reinforcement 20 can be provided with branch line outlets 26a on the cover member 26 in addition to the vertical wall 23 (Figure 10).

[0036] [Differentiation] The wire harness 2 in this modified example corresponds to the wire harness 1 of the previously described embodiment, in which the reinforcement 20 is replaced with the following reinforcement 120 (Figures 11 to 13). On the other hand, in this modified example, for the sake of explanation, the same harness body 10 as in the embodiment is used.

[0037] The reinforcement 120 in this modified example comprises a reinforcement body 121 made of synthetic resin and a cover member 126 made of synthetic resin, similar to the reinforcement 20 in the embodiment (Figures 11 and 12).

[0038] In this modified example, the reinforcement body 121 is provided with a harness routing space 122a on its outer wall surface 121a, similar to the reinforcement body 21 of the embodiment (Figures 11 to 13), and fixing pieces (not shown) are provided at both ends. However, the harness routing space 122a in this modified example is formed between a pair of opposing wall surfaces 123a, similar to the harness routing space 22a of the embodiment, but the configuration related to this space is different from that of the reinforcement body 21 of the embodiment.

[0039] In this modified example, the outer wall surface 121a of the reinforcement body 121 is provided with multiple sets of plate-shaped vertical walls 123 having one opposing wall surface 123a and plate-shaped vertical walls 123 having the other opposing wall surface 123a, with gaps 124 in the extending direction of the reinforcement body 121 (Figures 12 and 13).

[0040] Each vertical wall 123 is formed in the shape of a rectangular plate with a plane that runs along the extending direction of the reinforcement body 121. Each vertical wall 123 protrudes from the flat outer wall surface 121a of the reinforcement body 121 at the same height and spaced apart from each other. A pair of vertical walls 123, whose opposing wall surfaces 123a face each other, are each formed in the same shape, and an opening 123b is formed between the tips of the protruding ends from the outer wall surface 121a (Figures 12 and 13). Here, all vertical walls 123 are formed in the same shape. And here, all gaps 124 are also formed in the same shape.

[0041] In this modified example, the harness routing space 122a is formed by arranging the space and gap 124 between a pair of opposing wall surfaces 123a alternately in the extending direction of the reinforcement body 121 for a number of combinations of pairs of vertical walls 123 (Figures 12 and 13). The harness insertion opening 122b in this modified example is formed by arranging the opening 123b and gap 124 between a pair of vertical walls 123 alternately in the extending direction of the reinforcement body 121 for a number of combinations of pairs of vertical walls 123 (Figures 12 and 13).

[0042] Thus, multiple pairs of vertical walls 123 form gaps 124 between adjacent vertical walls 123 in the extending direction of the reinforcement body 121. Here, these multiple gaps 124 are formed with spacing in the extending direction of the reinforcement body 121. Therefore, in the wire harness 2 of this modified example, the branch lines (main branch lines) 13 of the harness body 10 can be pulled out from the gaps 124 to the outside of the harness routing space 122a (Figures 11 and 12). Specifically, the branch lines (main branch lines) 13 are pulled out from the outside of the harness routing space 122a from between two adjacent vertical walls 123 in the extending direction of the reinforcement body 121 in the gaps 124.

[0043] The cover member 126 is held in place by multiple vertical walls 123 in multiple pairs of vertical walls 123, thereby closing the harness insertion opening 122b (Figures 11 and 12).

[0044] In this modified wire harness 2, the harness routing space 122a (in other words, multiple pairs of vertical walls 123) provided on the outer wall surface 121a of the reinforcement body 121 and the cover member 126 restrict the path of the harness body 10 and suppress interference of the harness body 10 with surrounding components. Therefore, in this modified wire harness 2, the harness body 10 can be protected on the outer wall surface 121a of the reinforcement body 121 without using protective members such as protectors or corrugated tubes as in the conventional method. Consequently, in this modified wire harness 2, the deterioration of the quality of the harness body 10 can be suppressed, just like in the wire harness 1 of the embodiment.

[0045] Furthermore, in this modified wire harness 2, since the reinforcement body 121 is made of synthetic resin, just like the wire harness 1 of the embodiment, the vertical wall 123 can be molded together with the reinforcement body 121 during the molding process. Therefore, in this modified wire harness 2, the harness routing space 122a can be formed inexpensively on the outer wall surface 121a of the reinforcement body 121. Moreover, since this modified wire harness 2 does not require protective members such as protectors or corrugated tubes as in the conventional method, it is possible to reduce costs by reducing the number of parts.

[0046] Furthermore, in the wire harness 2 of this modified example, multiple gaps 124 that can be used as branch line exit points are arranged at intervals in the extending direction of the reinforcement body 121. In particular, in this wire harness 2, multiple gaps 124 of the same size are arranged at equal intervals in the extending direction of the reinforcement body 121. Therefore, in the wire harness 2 of this modified example, for example, the branch line (main branch line) 13 can be pulled out of the harness routing space 122a from a gap 124 near the branching point of the branch line (main branch line) 13 from the main line 12. Moreover, even if the harness body 10 of this modified example is replaced with one of a different size or with a branch line (main branch line) 13 at a different branching point, the branch line (main branch line) 13 can still be pulled out of the harness routing space 122a from a nearby gap 124.

[0047] Furthermore, in the wire harness 2 of this modified example, as shown in Figure 14, for example, by simply changing the number of pairs of vertical walls 123, a harness routing space 122a corresponding to the length of the main wire 12 and the position of surrounding components can be formed. In this wire harness 2, it is sufficient to prepare cover members 126 that match the number of pairs of vertical walls 123. Therefore, the wire harness 2 of this modified example can reduce design man-hours compared to conventional cases that use protective members such as protectors or corrugated tubes.

[0048] Furthermore, in the modified wire harness 2, the harness body 10 can be adapted to different sizes (radial dimensions) by changing the cover member 126 without changing the vertical wall 123 on the reinforcement body 121 side. As an example, in this case, two cover members 126 are prepared: one that corresponds to a cylindrical harness body 10 with a circular cross-section (for convenience, referred to as "first harness body 10A") (Figure 15, cover member 126A), and one that corresponds to a cylindrical harness body 10 with a larger radial size in the circular cross-section (for convenience, referred to as "second harness body 10B") (Figure 16, cover member 126B). Each cover member 126A and 126B is provided with a plate-shaped lid portion 126a that closes the harness insertion opening 122b, and plate-shaped side wall portions 126b that protrude in the same direction from two edges of the lid portion 126a along the extending direction of the reinforcement body 121. In the cover members 126A and 126B, a locking mechanism (not shown) is provided at the tip of the side wall portion 126b in the direction of protrusion from the lid portion 126a. By changing the length of the protruding side wall portion 126b in each of the cover members 126A and 126B, and by providing a locking mechanism at the tip of the side wall portion 126b, the cover members 126A and 126B can accommodate harness bodies 10 (10AA, 10B) of different sizes (radial size). Note that the side wall portion 126b does not close the gap 124.

[0049] For example, the first harness body 10A has an outer diameter equal to the distance between a pair of opposing wall surfaces 123a. The harness routing space 122a has a depth equal to the outer diameter of the first harness body 10A. The cover member 126A covers the first harness body 10A, which is inserted into the harness routing space 122a in its cylindrical form.

[0050] On the other hand, the cover member 126B has a pair of side wall portions 126b that extend in a protruding direction relative to the cover member 126A, and a locking mechanism is provided at the tip, thereby moving the position of the lid portion 126a away from the harness insertion opening 122b relative to the cover member 126A. In other words, this cover member 126B effectively extends the depth of the harness routing space 122a compared to the case where the cover member 126A is used. The second harness body 10B in this example is capable of changing shape between a columnar shape with a circular cross-section and a columnar shape with an elliptical cross-section. Therefore, this second harness body 10B deforms into an elliptical columnar shape and is inserted between a pair of opposing wall surfaces 123a, causing it to protrude from the harness insertion opening 122b. However, the cover member 126B effectively deepens the harness routing space 122a, allowing the second harness body 10B that protrudes from the harness insertion opening 122b to be housed within the harness routing space 122a.

[0051] Furthermore, in this modified example, the outer wall surface 121a of the reinforcement body 121 is provided with a harness holding portion 128 for holding the harness body 10 (Figures 11 to 13). This harness holding portion 128 holds the main wire 12 of the harness body 10 that is drawn out from one end or the other end of the harness routing space 122a. This harness holding portion 128 is formed integrally with the outer wall surface 121a of the reinforcement body 121. In other words, this harness holding portion 128 is formed together with the reinforcement body 121 during the molding process. As a result, in this modified example of the wire harness 2, compared to one in which a separate harness holding member is attached to the outer wall surface 121a of the reinforcement body 121, the number of parts can be reduced and dimensional control can be made easier, leading to a reduction in cost.

[0052] For example, this harness holding portion 128 is like a so-called band clamp and has a band portion 128a that is wrapped around the main wire 12 and a main body portion 128b that holds the band portion 128a wrapped around the main wire 12 (Figures 11 to 13). In this harness holding portion 128, the main body portion 128b is formed integrally with the outer wall surface 121a of the reinforcement body 121, and the band portion 128a extends from this main body portion 128b.
