[0053] [Implementation Method]

[0054] The wire harness manufacturing method involved in this embodiment manufactures... Figure 1 The wire harness WH is shown. Below, firstly, regarding... Figure 1 The basic structure of the wire harness WH shown in the figure will be explained, and then the wire harness manufacturing method will be explained in detail.

[0055] Figure 1The wiring harness WH shown, for example, is used to connect various devices mounted in a vehicle. Multiple wiring materials W used for power supply and signal communication are bundled into a single assembly, and the multiple wiring materials W are connected to each device via connectors or the like. The wiring harness WH in this embodiment includes wiring materials W, a protective component 1, and a bundling component 2. Furthermore, the wiring harness WH can also be configured to include various components such as cable loops, electrical junction boxes, fasteners, and connectors.

[0056] The wiring material W is, for example, an insulated wire formed by wrapping the core wire with an insulating sheath, which is obtained by bundling multiple conductive metal wires together. The wiring material W can also be formed by bundling multiple insulated wires. Alternatively, the wiring material W can be an insulated metal rod formed by wrapping a conductive metal rod with an insulating sheath. The protective component 1 is assembled to the wire harness WH, and the wiring material W is inserted and laid inside it, thereby externally mounting the wiring material W, protecting the wiring material W inside, and restricting the wiring path of the wiring material W. The protective component 1 is also called an external component or a protector. Here, the wiring path of the wiring material W in the protective component 1 is described as a straight path along a third direction Z, but it is not limited to this; it can also be a curved or zigzag path. The bundling component 2 bundles the wiring material W inside the protective component 1 to the protective component 1. The bundling component 2 is, for example, a so-called bundling strap, configured to include a head 2a and a strap portion 2b extending from the head 2a. The binding component 2 secures the wiring material W to the protective component 1 by locking the tape portion 2b, which is wrapped around the wiring material W and the protective component 1, at the head 2a.

[0057] Furthermore, for the wire harness WH shown in this embodiment, the protective member 1 has a temporary holding cutout 30 and a temporary holding protrusion 40 that temporarily hold the strap portion 2b of the bundling member 2 when the wiring material W is wired inside, thereby improving the workability when wiring and bundling the wiring material W. Hereinafter, the structure of the protective member 1 will be described in detail with reference to the figures.

[0058] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the protective component 1 includes a main body 10, an insertion hole 20, a temporary holding cutout 30, and a temporary holding protrusion 40. These components of the protective component 1, including the main body 10, the insertion hole 20, the temporary holding cutout 30, and the temporary holding protrusion 40, are integrally formed from an insulating resin material.

[0059] In the protective component 1, the main body 10 constitutes the primary component for protecting the wiring material W inside the wiring and restricting the wiring path. The main body 10 is formed in a generally groove shape, forming a wiring space SP inside. Specifically, the main body 10 is configured to include a bottom 11 and sidewalls 12. The bottom 11 is formed as a plate with its thickness direction along the first direction X. The bottom 11 is formed in a shape corresponding to the shape of the required wiring space SP, and here it extends linearly along the third direction Z. The sidewalls 12 protrude to one side from the bottom 11 and are formed as plates. Here, a pair of sidewalls 12 are provided at intervals in the second direction Y. The sidewalls 12 are respectively provided at the ends of the bottom 11 in the second direction Y.

[0060] The internal space of the main body 10, enclosed by the bottom 11 and a pair of sidewalls 12, constitutes the wiring space SP. The wiring space SP is for the wiring material W to be inserted and is the space where the wiring material W is located. The bottom 11 and the pair of sidewalls 12 form a straight wiring path.

[0061] Furthermore, the main body 10 forms a pair of wiring openings 13 and 14 and an opening 15 via a bottom 11 and a pair of sidewalls 12. Wiring openings 13 and 14 are openings through which wiring material W, which is wired into the wiring space SP, is inserted, and are formed at both ends of the main body 10 in the third direction Z. Wiring openings 13 and 14 are formed from the ends of the bottom 11 and the pair of sidewalls 12 in the third direction Z, and open along the third direction Z. Opening 15 is an opening for wiring the wiring material W into the wiring space SP, and is formed in the main body 10 opposite to the bottom 11 along the first direction X. Opening 15 is formed from the ends of the pair of sidewalls 12 on the side opposite to the bottom 11, and opens along the first direction X towards the side opposite to the bottom 11. In other words, the main body 10 can be said to have an opening 15 in the wiring space SP that opens to one side along the first direction X.

[0062] In addition, the protective component 1 may also have a cover component. After the wiring material W is wired in the wiring space SP and secured by the binding component 2, the cover component blocks the opening 15 of the main body 10.

[0063] The insertion hole 20 is formed through the main body 10 and is a hole through which the binding member 2 can be inserted throughout the wiring space SP. The insertion hole 20 is configured to be located on the wiring path of the wiring material W in the wiring space SP. That is, here, the insertion hole 20 is configured to be located on the wiring path formed by the wiring opening 13 and the wiring opening 14, and a binding member 2 for binding and fixing the wiring material W wired on the wiring path to the main body 10 is provided. The insertion hole 20 is provided at the bottom 11 of the main body 10 in a position sandwiched between a pair of sidewall portions 12. The insertion hole 20 is formed through the bottom 11 in a first direction X, connecting the inside and outside of the wiring space SP. A pair of insertion holes 20 are provided for each binding member 2. The pair of insertion holes 20 are formed at intervals in the bottom 11 along a direction that intersects with the wiring path of the wiring material W, which is here the second direction Y. Here, a pair of through holes 20 are formed at the ends of each side wall portion 12 of the bottom 11, and are formed in a generally rectangular shape that allows the strap portion 2b of the binding member 2 to be inserted. In addition, here, the pair of through holes 20 are formed in a position opposite to each other along the second direction Y, but they can also be formed in a position offset from each other along the third direction Z within the range that allows one binding member 2 to be inserted.

[0064] The temporary holding cut 30 is formed as a recess at its end 12a on the side of the opening 15 in the first direction X of the main body 10. This cut allows the binding member 2 to pass through the wiring space SP both inside and outside when the binding member 2 is inserted into the insertion hole 20. The temporary holding cut 30 and the temporary holding protrusion 40 together constitute the temporary holding portion 50. The temporary holding portion 50 is the portion that can temporarily hold the end of the strap portion 2b of the binding member 2 when the binding member 2 is inserted into the insertion hole 20.

[0065] Specifically, a temporary holding slit 30 is formed at the end 12a of the side wall portion 12 in the first direction X, on the side of the opening 15. The temporary holding slit 30 is formed to extend concavely from the end 12a of the side wall portion 12 in the first direction X toward the bottom 11. In other words, the temporary holding slit 30 can also be said to be formed by penetrating the side wall portion 12 in the second direction Y, connecting the inside and outside of the wiring space portion SP. By providing one temporary holding slit 30 for each of the pair of side wall portions 12, a pair of temporary holding slits 30 are provided in the second direction Y, separated by the wiring space portion SP. The pair of temporary holding slits 30 are formed at intervals along the direction intersecting the wiring path of the wiring material W, i.e., the second direction Y, and are arranged along the second direction Y, separated by a pair of insertion holes 20. Here, the pair of temporary holding slits 30 are each formed at the end 12a of each side wall portion 12 in the first direction X, and are formed into a generally rectangular shape that allows the strap portion 2b of the binding member 2 to be inserted. In addition, here, a pair of temporary holding cuts 30 are formed in a position opposite each other along the second direction Y, but they can also be formed in a position that is offset from each other along the third direction Z within the range that allows each end of the binding member 2, which is inserted into the insertion hole 20, to be inserted.

[0066] The temporary holding protrusion 40 is formed by protruding from the main body 10 toward the temporary holding cutout 30, and hooks and temporarily holds the binding member 2 when it is inserted into the temporary holding cutout 30. As described above, the temporary holding protrusion 40 and the temporary holding cutout 30 together constitute the temporary holding part 50.

[0067] Specifically, a temporary holding protrusion 40 is formed on the side wall portion 12 constituting the main body portion 10. More specifically, the temporary holding protrusion 40 is formed to protrude from the side wall portion 12 toward the inside of the temporary holding cutout portion 30 when viewed along the second direction Y (in other words, when viewed from the front view of the temporary holding cutout portion 30). Here, the temporary holding protrusion 40 protrudes outward from the outer surface of the side wall portion 12 (the surface opposite to the wiring space portion SP side) in the second direction Y, and is formed in a claw shape by protruding toward the temporary holding cutout portion 30 along the third direction Z. The temporary holding protrusion 40 is configured to hook and temporarily hold the strap portion 2b of the binding member 2 through the claw shape. A pair of temporary holding protrusions 40 are provided opposite each other in the third direction Z, separated by the temporary holding cutout portion 30.

[0068] One of the pair of temporary retaining protrusions 40 is located on the third-direction Z side relative to the temporary retaining incision 30, protruding from the edge of the sidewall portion 12 forming the temporary retaining incision 30 to the other side along the third-direction Z. The other of the pair of temporary retaining protrusions 40 is located on the other side of the third-direction Z relative to the temporary retaining incision 30, protruding from the edge of the sidewall portion 12 forming the temporary retaining incision 30 to one side along the third-direction Z.

[0069] Each temporary holding protrusion 40 is formed with a tapering shape towards its protruding end 40a. The protruding ends 40a of a pair of temporary holding protrusions 40 are arranged at a distance G1 along the third direction Z, to the extent that the strap portion 2b of the binding member 2 can pass through. In other words, in each temporary holding protrusion 40, the amount of protrusion from the edge of the sidewall portion 12 along the third direction Z is set such that the distance G1 between the protruding ends 40a along the third direction Z is a distance to the extent that the strap portion 2b can pass through.

[0070] Here, a pair of temporary holding protrusions 40 constitute a temporary holding portion 50. That is, a temporary holding portion 50 is composed of a temporary holding cutout 30 and a pair of temporary holding protrusions 40. Furthermore, as described in the explanation of the pair of temporary holding cutouts 30, the temporary holding portions 50 are provided in pairs in the second direction Y, separated by the wiring space portion SP, by providing one of each of the pair of sidewall portions 12. In other words, the combination of the temporary holding cutout 30 constituting the temporary holding portion 50 and the temporary holding protrusions 40 is provided in pairs in the second direction Y, separated by the wiring space portion SP.

[0071] Next, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The manufacturing method (wire harness manufacturing method) for the wire harness WH constructed as described above will be explained. In the following explanation, ... Figure 4 The following explanation is based on the flowchart, with appropriate reference to other diagrams. The manufacturing method of the wire harness WH described below can be performed manually by operators using various devices, equipment, and jigs, or it can be automated using various manufacturing devices.

[0072] The manufacturing method of the wire harness WH in this embodiment includes: a insertion process (step S1), a temporary holding process (step S2), a wiring process (step S3), and a bundling process (step S4). Here, the manufacturing method of the wire harness WH will be described in the case where it is performed manually by an operator.

[0073] First, such as Figure 5As shown, as part of the insertion process, the operator inserts the strapping member 2 into the insertion hole 20 (step S1). Here, the strapping member 2 inserts the end portion of the strap 2b from the wiring space SP side into one of the insertion holes 20. Then, the strapping member 2 folds the end portion of the strap 2b back outside the wiring space SP and inserts the end portion of the strap 2b towards the wiring space SP side relative to the other insertion hole 20. In this state, the strapping member 2 is in a state where the strap 2b is inserted into the pair of insertion holes 20 and folded back into a roughly U-shape. In addition, in this state, the end portion of the strap 2b of the strapping member 2 is located near a temporary holding part 50, and the end portion on the head 2a side is located near another temporary holding part 50.

[0074] Next, as a temporary holding process, the operators, such as Figure 5 As shown by the middle arrow, each end of the strap portion 2b of the binding member 2, which is inserted through the insertion hole 20, is inserted into the temporary holding cutout portion 30 constituting each temporary holding portion 50. Then, as... Figure 6 As shown, the operator hooks each end of the strap portion 2b of the bundling member 2, which is inserted through the temporary holding slit 30, onto the temporary holding protrusion 40 constituting each temporary holding portion 50, thereby temporarily holding it at the temporary holding protrusion 40 (step S2). Here, the end portion of the strap portion 2b of the bundling member 2 is led out from the wiring space portion SP side to one side via the opening 15 along the first direction X, and folded back to the other side along the first direction X. Moreover, the bundling member 2 is temporarily held at the temporary holding protrusion 40 by pressing the folded end of the strap portion 2b into the temporary holding slit 30 constituting a temporary holding portion 50 and hooking it onto the temporary holding protrusion 40. Similarly, the binding member 2 is temporarily held in the temporary holding protrusion 40 by extending the end of the head 2a side of the strap 2b out from the wiring space SP side in the first direction X along the opening 15, pressing it into and inserting it into the temporary holding cutout 30 that constitutes another temporary holding part 50, and hooking it onto the temporary holding protrusion 40.

[0075] In this state, the protective member 1 and the binding member 2 constitute the protective member assembly 100. That is, the protective member assembly 100 includes: a protective member 1 capable of housing wiring material W; and a binding member 2 capable of binding the wiring material W, which is housed inside the protective member 1, to the protective member 1. As described above, in this state, the insertion hole 20 is fully inserted through the binding member 2 throughout the wiring space SP, and the temporary holding cutout 30 is also fully inserted through the binding member 2. Furthermore, the temporary holding protrusion 40 hooks onto and temporarily holds the binding member 2 while it is inserted through the temporary holding cutout 30.

[0076] Next, as Figure 7 As shown, as part of the wiring process, the operator lays the wiring material W in the wiring space SP while the bundling member 2 is temporarily held by the temporary holding protrusion 40 (step S3). Here, the wiring material W is stored in the wiring space SP through the opening 15, and in the wiring space SP, the wiring is laid on the wiring path formed by the wiring openings 13 and 14.

[0077] Next, as Figure 1 As shown, in the bundling process, the operator removes the end of the bundling member 2 from the temporary holding protrusion 40, and uses the bundling member 2 to bundle the wiring material W, which is in the wiring space SP, to the main body 10 (step S4). Here, with the strap 2b wrapped around the wiring material W and the bottom 11 of the main body 10 via the insertion hole 20, the end of the strap 2b is secured to the head 2a, thereby bundling and fixing the wiring material W to the bottom 11. Thus, the operator ends the manufacturing method of the wire harness WH. In this state, the insertion hole 20 is inserted through the bundling member 2 throughout the wiring space SP, while the temporary holding cut 30 and the temporary holding protrusion 40 are removed.

[0078] The manufacturing method described above, the wire harness WH, the protective component assembly 100, and the protective component 1, before routing the wiring material W into the wiring space SP of the main body 10, insert the end of the binding member 2, which is inserted through the insertion hole 20, into the temporary holding cutout 30 provided at the end 12a on the opening 15 side of the main body 10, and temporarily hold it in the temporary holding protrusion 40, thereby improving the workability when routing and binding the wiring material W. That is, by temporarily holding the end of the binding member 2 in the temporary holding protrusion 40, the manufacturing method, the wire harness WH, the protective component assembly 100, and the protective component 1 can prevent the end of the binding member 2 from falling into the wiring space SP and being pressed under the wiring material W when routing the wiring material W into the wiring space SP. Therefore, when wiring the wiring material W in the wiring space SP, the manufacturing method, wiring harness WH, protective component assembly 100, and protective component 1 ensure that the bundling member 2 does not obstruct the wiring and that unnecessary time is saved by pulling out the bundling member 2 that is pressed under the wiring material W. Furthermore, after wiring the wiring material W in the wiring space SP, the manufacturing method, wiring harness WH, protective component assembly 100, and protective component 1 allow the bundling member 2, which is temporarily held in the temporary holding protrusion 40, to be removed and the wiring material W to be bundled and fixed to the protective component 1. As a result, the manufacturing method, wiring harness WH, protective component assembly 100, and protective component 1 described above improve the workability of wiring and bundling the wiring material W, thereby properly bundling the wiring material W.

[0079] In the manufacturing method, wire harness WH, protective component assembly 100, and protective component 1 described above, a pair of temporary holding protrusions 40 are provided opposite each other in each temporary holding portion 50, separated by a temporary holding cutout 30. According to this structure, the protective component 1 can reliably and temporarily hold the end of the binding member 2 inserted into the temporary holding cutout 30 using the pair of temporary holding protrusions 40. Furthermore, with this structure, the protective component 1 can be configured to easily hold the end of the binding member 2 temporarily from the opening 15 side to the temporary holding protrusion 40, and to easily detach the end of the binding member 2 temporarily held in the temporary holding protrusion 40 from the opening 15 side. As a result, the manufacturing method, wire harness WH, protective component assembly 100, and protective component 1 described above can further improve the workability of wiring and bundling the wiring material W, and more appropriately bundle the wiring material W.

[0080] Furthermore, in the manufacturing method, wire harness WH, and protective component 1 described above, a combination of a temporary holding cutout 30 and a temporary holding protrusion 40 constituting a temporary holding portion 50 is provided across the wiring space portion SP. With this structure, the protective component 1 can temporarily hold the two ends of the binding component 2, which is inserted into the insertion hole 20, via the temporary holding protrusion 40. In this respect, the manufacturing method, wire harness WH, protective component assembly 100, and protective component 1 described above can further improve the workability when wiring and binding the wiring material W, and can bind the wiring material W more appropriately.

[0081] Furthermore, the wire harness manufacturing method, wire harness, protective component assembly, and protective component involved in the above-described embodiments of the present invention are not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

[0082] In the above description, the case where the protective component 1 is an external component or a protector has been described, but it is not limited thereto. For example, it may also be configured as part of a housing such as an electrical junction box.

[0083] In the above description, the case where a pair of temporary holding protrusions 40 are provided across the temporary holding cutouts 30 is described, but this is not a limitation; at least one pair is sufficient. Similarly, in the above description, the case where a combination of a pair of temporary holding cutouts 30 and temporary holding protrusions 40 is provided across the wiring space SP is described, but this is not a limitation; at least one set is sufficient.

[0084] The spacing G1 between the protruding ends 40a of the pair of temporary retaining protrusions 40 described above can be appropriately changed according to the width of the strap portion 2b of the binding member 2 applied to the protective member 1. Figure 8 , Figure 9 In the modified example shown, the protective member 1A has a pair of temporary holding protrusions 40Aa formed such that the distance G2 between the protruding ends 40Aa is relatively large compared to the distance G1 between the protruding ends 40Aa of the pair of temporary holding protrusions 40. That is, the protruding ends 40Aa of the pair of temporary holding protrusions 40Aa are located at a distance G2 along the third direction Z, such that the width of the strap portion 2b of the strapping member 2 is wider than that of the strapping member 2. In other words, in each temporary holding protrusion 40A, the amount of protrusion from the edge of the sidewall portion 12 along the third direction Z is set such that the distance G2 between the protruding ends 40Aa and each other along the third direction Z is such that the distance is wide enough for the strap portion of the strapping member to pass through. Even in this case, the protective member 1A, as described above, can properly strap the wiring material W and can properly temporarily hold the strapping member 2 according to the width of the strap portion 2b of the strapping member 2 applied thereto.

[0085] The temporary holding protrusion 40 described above is formed in the form of a claw, protruding from the outer surface of the side wall portion 12 (the side opposite to the wiring space portion SP side) outward in the second direction Y, and protruding along the third direction Z towards the temporary holding cutout portion 30. However, it is not limited to this. Figure 10 , Figure 11 In the modified example shown, the protective member 1B has a pair of temporary holding protrusions 40B that protrude inward in the second direction Y from the inner surface of the sidewall portion 12 (the surface on the side of the wiring space portion SP) and protrude in the third direction Z toward the temporary holding cutout portion 30, forming a claw shape. Furthermore, although the shape of the insertion hole 20 in this modified example is slightly different from that in the embodiment described above, it is essentially the same structure. Even in this case, the protective member 1B can still properly secure the wiring material W as described above.

[0086] The wire harness manufacturing method, wire harness, protective component assembly, and protective component involved in this embodiment can also be constructed by appropriately combining the constituent elements of the embodiments and variations described above.
