[0003] Japanese Patent Application Laid-Open No. 2000-268899

[0004] It is desirable to suppress the generation of waste when changing a wire harness from a packaged form to a wired form.

[0005] Therefore, an object of the present disclosure is to suppress the generation of waste when a wire harness is changed from a packaged form to a wired form.

[0006] The packaged wire harness of the present disclosure is a packaged wire harness including a wire harness including a first path portion and a second path portion, and a temporary fastening tape including a first winding portion wound around the first path portion, a second winding portion wound around the second path portion, and a connecting portion connecting the first winding portion and the second winding portion.

[0007] The wiring configuration wire harness of the present disclosure is a wiring configuration wire harness including: a wire harness including a first path portion and a second path portion; a first temporary fastening tape remaining portion including a first winding portion wound around the first path portion and a first connecting partial disconnection portion extending from the first winding portion; and a second temporary fastening tape remaining portion including a second winding portion wound around the second path portion and a second connecting partial disconnection portion extending from the second winding portion and disconnected from the first connecting partial disconnection portion.

[0008] According to the present disclosure, generation of waste is suppressed when a wire harness is changed from a packaged form to a wired form.

Fig. 3 is a schematic diagram showing a packaged wire harness. Fig. 4 is a partially enlarged view of Fig. 3. Fig. 5 is a cross-sectional view taken along line V-V in Fig. 4. Fig. 6 is an explanatory diagram showing an example of the work of assembling a packaged wire harness into a vehicle.

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The packaged wire harness of the present disclosure is as follows.

[0012] (1) A packaged wire harness including a wire harness including a first path portion and a second path portion, and a temporary fastening tape including a first winding portion wound around the first path portion, a second winding portion wound around the second path portion, and a connecting portion connecting the first winding portion and the second winding portion.

[0013] According to the present disclosure, in the packaged form, the first path portion and the second path portion are maintained in a connected state via the temporary fixing tape. This prevents the wire harness from becoming tangled or from having a portion of the wire harness get caught on another portion. This makes it easy to handle the packaged wire harness. Furthermore, by severing the connecting portion, the packaged wire harness can be unwound and changed to the wiring form. At this time, in the wiring form, the first winding portion and a portion of the connecting portion remain on the first path portion side, and the second winding portion and the remaining portion of the connecting portion remain on the second path portion. This prevents waste from being generated when the wire harness is changed from the packaged form to the wiring form.

[0014] (2) In the packaged wire harness of (1), the connecting portion may be formed with a breakable portion that is processed to be easily broken.

[0015] In this case, the connecting portion can be broken at the breaking processed portion, which makes it easier to stabilize the shape of the portion of the temporary fixing tape that remains in the first path portion and the shape of the portion that remains in the second path portion.

[0016] (3) In the packaging form wire harness of (1) or (2), the first path portion may be a trunk portion, the second path portion may be a branch portion branching from the trunk portion and thinner than the trunk portion, the branch portion having at least one support point that is supported at a fixed position in a vehicle, and the second winding portion may be wound around the branch portion at a position excluding the at least one support point.

[0017] The branch wire portion, except for at least one support location, may swing on the vehicle and come into contact with the vehicle. The second winding portion, which is wound around the branch wire portion at a position other than the at least one support location, can prevent the branch wire portion from coming into direct contact with the vehicle.

[0018] (4) In the packaging form wire harness of any one of (1) to (3), the first path portion may be a trunk portion, the second path portion may be a branch portion branching from the trunk portion and thinner than the trunk portion, and the second winding portion may be wound between a base end and a tip end of the branch portion.

[0019] The portion of the branch wire between the base end and the tip end may swing and come into contact with the vehicle. The second winding portion wound between the base end and the tip end of the branch wire can prevent the branch wire from coming into direct contact with the vehicle.

[0020] (5) In the wire harness of any one of (1) to (4), the first winding portion may be a portion wound around the first path portion one or more times but less than two times, and the second winding portion may be a portion wound around the second path portion one or more times but less than two times.

[0021] This allows the first winding portion to be formed by winding the tape around the first path portion one or more times but less than two times, and the second winding portion to be formed by winding the tape around the second path portion one or more times but less than two times. Therefore, the wire harness can be easily temporarily fastened with the temporary fastening tape and packed.

[0022] (6) In the packaging form wire harness of (5), the first winding portion may include a pair of first end portions that face each other in the circumferential direction on the outer periphery of the first path portion, the second winding portion may include a pair of second end portions that face each other in the circumferential direction on the outer periphery of the second path portion, and the connecting portion may be a portion in which a one-side connecting portion that connects one of the pair of first end portions to one of the pair of second end portions and a other-side connecting portion that connects the other of the pair of first end portions to the other of the pair of second end portions are attached to each other at their surfaces.

[0023] In this case, the first winding portion is likely to remain in the first path portion and the second winding portion is likely to remain in the second path portion, because the first and second winding portions are easily temporarily fastened with a temporary fastening tape to form a packaged wiring harness, even if the first and second winding portions are severed.

[0024] (7) In the packaging form wire harness according to any one of (1) to (6), the temporary fixing tape may be formed by a self-fusing tape.

[0025] In this way, the first and second winding portions formed by the self-fusing tape can easily protect the wire harness.

[0026] The wiring form wire harness of the present disclosure is as follows.

[0027] (8) A wiring configuration wire harness including: a wire harness including a first path portion and a second path portion; a first temporary fixing tape remaining portion including a first winding portion wound around the first path portion and a first connecting partial cut portion extending from the first winding portion; and a second temporary fixing tape remaining portion including a second winding portion wound around the second path portion and a second connecting partial cut portion extending from the second winding portion and cut from the first connecting partial cut portion.

[0028] According to the present disclosure, in the packaged form, the first path portion and the second path portion are maintained in a connected state by leaving the first connection partial disconnection portion and the second connection partial disconnection portion in the state before separation. This prevents the wire harness from becoming tangled or one part of the wire harness from getting caught on another part. This makes it easy to handle the packaged wire harness. Then, by separating the first connection partial disconnection portion and the second connection partial disconnection portion, the packaged wire harness can be unwrapped and changed to a wiring form. At this time, in the wiring form, the remaining part of the first temporary fixing tape remains on the first path portion side, and the remaining part of the second temporary fixing tape remains on the second path portion side. This prevents waste from being generated when changing the wire harness from the packaged form to the wiring form.

[0029] [Details of the embodiment of the present disclosure] Specific examples of the packaged wire harness and the wiring wire harness of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0030] [Embodiments] Hereinafter, a packaged wire harness and a wired wire harness according to embodiments will be described. Fig. 1 is a schematic diagram showing a wire harness 10 wired in a vehicle 1. Fig. 2 is an explanatory diagram showing problems in a packaged form. Fig. 3 is a schematic diagram showing a packaged wire harness 10P. Fig. 4 is a partially enlarged view of Fig. 3, and Fig. 5 is a cross-sectional view taken along line V-V in Fig. 4. Note that in each drawing, the outline of the wire harness 10 may be depicted regardless of the number of electric wires included in the wire harness 10.

[0031] The wire harness 10 is a wiring member that electrically connects electrical components 16A, 16B, and 16C to one another in the vehicle 1. The wire harness 10 includes a plurality of electric wires 11 (see FIG. 5 ). The electric wires 11 may be signal wires, power wires, or earth wires. The wire harness 10 may also include optical fiber cables.

[0032] The plurality of electric wires 11 are branched and bundled according to the positions of the electric components 16A, 16B, 16C to be connected and according to wiring routes that can be set in the vehicle 1. Connectors 12A, 12B, 12C are connected to the ends of the plurality of electric wires 11, and the electric wires 11 are connected to the electric components 16A, 16B, 16C via the connectors 12A, 12B, 12C, respectively (see FIG. 1 ).

[0033] The wire harness 10 is deployed in accordance with the positions and wiring paths of the electrical components 16A, 16B, and 16C when installed in the vehicle 1. In the vehicle, the wire harness 10 is arranged along the wiring path set in the vehicle, and the connectors 12A, 12B, and 12C at the ends are arranged at positions connectable to the electrical components 16A, 16B, and 16C to be connected thereto.

[0034] The wire harness 10 is rolled or bent into a state suitable for storage, transportation, etc. before being installed in the vehicle 1. The state in which the wire harness 10 is rolled or bent into a state suitable for storage, transportation, etc. is a packaged wire harness 10P.

[0035] The packaged wire harness 10P is more compact than the wire harness 10 that is unfolded along a wiring path in a vehicle. The packaged wire harness 10P can be stored or transported in a small area.

[0036] The wire harness 10 includes a first path portion 13 and a second path portion 14. In the present embodiment, the wire harness 10 includes the first path portion 13 as a main wire portion 13 and the second path portion 14 as a branch wire portion 14.

[0037] That is, the wire harness 10 has a plurality of electric wires 11 bundled together while branching out. The bundling member for bundling the plurality of electric wires 11 may be, for example, an adhesive tape, a cable tie, a protective tube, or a resin protector. For example, the main wire portion 13 is a portion that contains the greatest number of electric wires 11. The branch wire portion 14 is a portion from the main wire portion 13 where a portion of the electric wires 11 included in the main wire portion 13 branches off from the remaining portion. In other words, the branch wire portion 14 is a portion that branches out from the main wire portion 13. It is assumed that the branch wire portion 14 is thinner than the main wire portion 13. In this embodiment, an example is shown in which one branch wire portion 14 branches out from one main wire portion 13.

[0038] It is also conceivable that a plurality of branch wire portions branch off from the trunk wire portion. It is also conceivable that the branch wire portion is further divided into a plurality of branch wire portions. The first path portion and the second path portion may be different path portions in the wire harness, and may be portions that can maintain the wire harness in a compact form by holding the different path portions close to each other. For example, the first path portion and the second path portion may be different portions in the trunk wire portion. The first path portion and the second path portion may be two different branch wire portions branching off from the trunk wire portion.

[0039] In this embodiment, connectors 12A and 12C are connected to both ends of trunk line 13. Branch line 14 branches off from the middle of trunk line 13 in the longitudinal direction. For example, branch line 14 branches off and extends from a portion of trunk line 13 closer to connector 12A. Connector 12B is connected to the tip of branch line 14.

[0040] When the wire harness 10 is packaged, it is assumed that, for example, a portion of the trunk portion 13 near the connector 12C is rolled up ( FIG. 2 ). In this case, if the branch portion 14 is free relative to the trunk portion 13, the branch portion 14 may approach the rolled portion of the trunk portion 13 (see the branch portion 14 indicated by the two-dot chain line in FIG. 2 ). In this case, the branch portion 14 may wrap around or become entangled with the trunk portion 13. Furthermore, the connector 12B may get caught on the connector 12C or on a clamp component or other exterior component attached to the trunk portion 13 for securing the vehicle. Furthermore, if the trunk portion 13 has a branch portion other than the branch portion 14, the branch portion 14 may get entangled with the other branch portion.

[0041] In these cases, the wire harness 10 must be unfolded from its packaged form to its wired form while untangling any windings or tangles in the branch wires and removing any snags between components, which can make the unfolding process cumbersome.

[0042] Therefore, in the packaging form, it is assumed that the branch wire portion 14 is temporarily fixed to another portion of the wire harness 10, for example, the middle portion in the longitudinal direction of the trunk wire portion 13. In this case, free movement of the branch wire portion 14 is restricted during storage or transportation, and the branch wire portion 14 is less likely to be tangled or caught on another portion of the wire harness 10.

[0043] To temporarily fasten the branch wire portion 14, it is conceivable to use a slit tape as disclosed in Patent Document 1, or to use a strip-shaped hook and loop fastener having a hook surface and a loop surface.

[0044] However, the slit tape disclosed in Patent Document 1 is wound around both the main wire and the branch wire at the same time, and is assumed to be removed from both the main wire and the branch wire after temporary fixing. Therefore, no measures are taken to prevent the slit tape from remaining on the main wire and the branch wire. As a result, the slit tape generates waste when wiring the wire harness.

[0045] Furthermore, the strip-shaped hook-and-loop fastener can be repeatedly attached and detached. Therefore, if the hook-and-loop fastener is collected when wiring the wire harness after the temporary fastening is completed, the hook-and-loop fastener can be reused. However, it may be difficult to completely collect and reuse the hook-and-loop fastener. Furthermore, the hook-and-loop fastener may become attached to a part having a loop surface in the vehicle, such as a carpet. If the hook-and-loop fastener becomes attached to the carpet, it may cause pilling of the carpet.

[0046] In the present disclosure, when the wire harness 10 is changed from a packaged form to a wiring form, the following temporary fixing tape 20 is used to temporarily fix the branch wire portion 14 to the trunk wire portion 13 in order to suppress the generation of waste.

[0047] That is, the packaged wire harness 10P includes the wire harness 10 and the temporary fixing tape 20.

[0048] The temporary fixing tape 20 includes a first wrapped portion 22 , a second wrapped portion 24 , and a connecting portion 26 .

[0049] The first winding portion 22 is a portion wound around the main line portion 13 as a first path portion. The second winding portion 24 is a portion wound around the branch line portion 14 as a second path portion. The connecting portion 26 is a portion connecting the first winding portion 22 and the second winding portion 24.

[0050] Here, "wound" may be considered to mean surrounding the entire circumference of the target portion. For example, first winding portion 22 may be a portion that surrounds the entire circumference of main wire portion 13. Also, second winding portion 24 may be a portion that surrounds the entire circumference of branch wire portion 14. "Wrapping" first winding portion 22 or second winding portion around a target portion may be understood to mean "wrapping" the first winding portion 22 or second winding portion around the target portion one or more times.

[0051] The temporary fixing tape 20 may be formed, for example, by an adhesive tape having a strip-shaped substrate and an adhesive layer. The adhesive layer of the adhesive tape can adhere to the surface of the trunk wire portion 13 or the branch wire portion 14. The adhesive layers of the adhesive tape can adhere to each other. Furthermore, the adhesive layer of the adhesive tape can adhere to the strip-shaped substrate from the side opposite the adhesive layer. Such an adhesive tape may be, for example, a PVC (polyvinyl chloride) tape.

[0052] The temporary fixing tape 20 may be a self-fusing tape. The self-fusing tape is a tape that self-fuse and is made of, for example, butyl rubber. The self-fusing tape can self-fuse at the contact points between the self-fusing tapes. The self-fusing tape is generally 0.5 mm or more thick, which is thicker than PVC tape. By using a self-fusing tape as the temporary fixing tape 20, the protection effect of the trunk wire portion 13 and the branch wire portion 14 is also enhanced.

[0053] The first winding portion 22 may be a portion wound one or more times but less than two times around the trunk portion 13. The first winding portion 22 may be configured to wind only one time around the trunk portion 13, i.e., to surround the trunk portion 13 exactly once. The first winding portion 22 does not have to be wound around the trunk portion 13 in a three-dimensional spiral.

[0054] The second winding portion 24 may be a portion wound one or more times but less than two times around the branch wire portion 14. The second winding portion 24 may be configured to wind only one time around the branch wire portion 14, i.e., to surround the branch wire portion 14 exactly once. The second winding portion 24 does not have to be wound around the branch wire portion 14 in a three-dimensional spiral.

[0055] If the first winding portion 22 and the second winding portion 24 are configured to be wrapped around the main line portion 13 or the branch line portion 14 one or more times but less than two times, the wrapping can be performed more easily than when the tape is wrapped around the target portion in a three-dimensional spiral shape.

[0056] However, the first and second wrapping portions may be portions in which the tape is wrapped around the target portion in a three-dimensional spiral shape.

[0057] The connecting portion 26 may have the following configuration: The first winding portion 22 includes a pair of first end portions 22e1, 22e2 that face each other in the circumferential direction on the outer periphery of the main wire portion 13.

[0058] The second winding portion 24 includes a pair of second end portions 24e1, 24e2 that face each other in the circumferential direction on the outer periphery of the branch wire portion 14.

[0059] The connecting portion 26 includes a one-side connecting portion 27 and a second-side connecting portion 28. The one-side connecting portion 27 is a rectangular portion connecting the first end 22e1, which is one of the pair of first end portions 22e1, 22e2, to the second end 24e1, which is one of the pair of second end portions 24e1, 24e2. The other-side connecting portion 28 is a rectangular portion connecting the first end 22e2, which is the other of the pair of first end portions 22e1, 22e2, to the second end 24e2, which is the other of the pair of second end portions 24e1, 24e2.

[0060] The one-side connecting portion 27 and the other-side connecting portion 28 have the same shape and are overlapped between the first winding portion 22 and the second winding portion 24. The one-side connecting portion 27 and the other-side connecting portion 28 are opposed to each other with their surfaces facing each other and adhered to each other. Preferably, the entire area of ​​the one-side connecting portion 27 and the entire area of ​​the other-side connecting portion 28 face each other and are adhered to each other. If the temporary fixing tape 20 is an adhesive tape, the one-side connecting portion 27 and the other-side connecting portion 28 may be adhered to each other via an adhesive layer. If the temporary fixing tape 20 is a self-fusing tape, the one-side connecting portion 27 and the other-side connecting portion 28 may be adhered to each other by self-fusing.

[0061] The temporary fixing tape 20 temporarily fixes the branch wire portion 14 to the trunk wire portion 13, for example, as follows.

[0062] That is, the branch wire portion 14 is disposed so as to extend along the main wire portion 13. It is preferable that a gap be provided between the branch wire portion 14 and the main wire portion 13.

[0063] The tape is folded back at a middle portion in the longitudinal direction, with a parallel arrangement of trunk portion 13 and branch portion 14 disposed therebetween. For example, trunk portion 13 is disposed at the folded portion. The folded portion is wound around trunk portion 13 once.

[0064] Branch wire portion 14 is disposed at a position spaced apart from trunk wire portion 13. Branch wire portion 14 is sandwiched between two portions of the tape that are distant from the folded-back portion. Each of the two portions of the tape that are distant from the folded-back portion is wound halfway around branch wire portion 14. Thus, the tape as a whole is wound one turn around branch wire portion 14, surrounding the entire circumference of branch wire portion 14.

[0065] Both ends of the portion of the tape that is wound one full turn around the trunk wire portion 13 are first ends 22e1, 22e2 that face each other on the branch wire portion 14 side. One end of each of two portions of the tape that are wound half a turn around the branch wire portion 14 is second ends 24e1, 24e2 that face each other on the trunk wire portion 13 side. The portion of the tape located between the first end 22e1 and the second end 24e1 is one-side connecting portion 27, and the portion of the tape located between the first end 22e1 and the second end 24e1 is one-side connecting portion 27. One-side connecting portion 27 and other-side connecting portion 28 can face each other and be in surface contact with each other between the trunk wire portion 13 and the branch wire portion 14. One-side connecting portion 27 and other-side connecting portion 28 are overlapped so as to be in surface contact with each other, and these portions are joined together.

[0066] The tape is cut so as to extend from the branch wire portion 14 on the side opposite to the main wire portion 13. The ends of the tape are overlapped so as to be in surface contact with each other, and the overlapping portions are joined to form the outer joint end portion 29.

[0067] When the temporary fixing tape 20 is formed of an adhesive tape, the adhesive tape can be attached to the surfaces of the trunk wire portion 13 and the branch wire portion 14 via the adhesive layer. In addition, the adhesive tapes can also be attached to each other via the adhesive layer. Therefore, the temporary fixing state is maintained.

[0068] When the temporary fixing tape 20 is formed from a self-fusing tape, the self-fusing tape can self-fuse at least at the connecting portion 26 and the outer joint end portion 29. As a result of the tape portions being kept joined together at the connecting portion 26 and the outer joint end portion 29, the first wrapping portion 22 is kept wound around the trunk wire portion 13, and the second wrapping portion 24 is kept wound around the branch wire portion 14. Note that the self-fusing tape can be fused to the trunk wire portion 13 or the branch wire portion 14 depending on the relationship between the material of the self-fusing tape and the surface material (coating material) of the trunk wire portion 13 or the branch wire portion 14, etc.

[0069] The winding configuration of the temporary fixing tape 20 around the trunk wire portion 13 and the branch wire portion 14 is not limited to the above example. For example, the outer joint end portion 29 may be wound around the second winding portion 24. Also, the inner end portion of the tape may be on the surface of the trunk wire portion 13 or the branch wire portion 14, and the intermediate portion of the tape in the longitudinal direction may be located on the inner end portion of the tape. The outer end portion of the tape may be located on the intermediate portion of the tape in the longitudinal direction.

[0070] The connecting portion 26 may have a breakable portion 26L formed therein, which is made to be easily broken. The breakable portion 26L is a portion of the connecting portion 26 that is made to be more easily broken than other portions. The breakable portion 26L is formed, for example, along the width direction of the connecting portion 26. The breakable portion 26L may be, for example, a portion in which a plurality of holes or slits are formed intermittently. The breakable portion 26L may be a portion in which a single slit is formed along the width direction of the connecting portion 26.

[0071] The breaking portion 26L is preferably formed at a position away from the portion of the connecting portion 26 that continues to the first winding portion 22 and the second winding portion 24. The breaking portion 26L may be formed at a center position between the first winding portion 22 and the second winding portion 24.

[0072] The position of the first winding portion 22 on the trunk portion 13 and the position of the second winding portion 24 on the branch portion 14 are arbitrary. For example, the first winding portion 22 and the second winding portion 24 may be set at positions that allow the branch portion 14 to be held along the trunk portion 13.

[0073] When the branch wire portion 14 has at least one support point that is supported at a fixed position on the vehicle 1, the second winding portion 24 may be wound around a position of the branch wire portion 14 excluding the at least one support point. For example, the base end of the branch wire portion 14 that connects to the trunk wire portion 13 is support point 14a. It is assumed that the trunk wire portion 13 is fixed with a clamp or the like to prevent it from moving on the vehicle 1. Furthermore, since the trunk wire portion 13 itself is assumed to have a certain degree of rigidity, it is also supported at a fixed position on the vehicle 1 between the fixed points of the trunk wire portion 13. It is also assumed that the base end of the branch wire portion 14 that connects to the trunk wire portion 13 is also a support point that is supported at a fixed position on the vehicle 1. Furthermore, the tip end of the branch wire portion 14 is connected to an electrical component 16B via a connector 12B. The electrical component 16B itself is fixed at a fixed position on the vehicle 1 with a screw or the like. Therefore, the tip end of the branch wire portion 14 is also an example of support point 14b. It is also conceivable that a band clamp or a sleeve clamp is attached to the longitudinal intermediate portion of the branch line portion 14, and the longitudinal intermediate portion of the branch line portion 14 is fixed to the vehicle via the clamp. The portion of the branch line portion 14 where the clamp is attached can also be an example of a support portion.

[0074] It is considered that the branch wire portion 14 itself is thinner than the trunk wire portion 13 and is more likely to deform. For this reason, it is considered that the portion of the branch wire portion 14 between the support points 14a and 14b will deform and move within the vehicle 1 and come into contact with the vehicle 1. For example, it is considered that the longitudinal middle portion of the branch wire portion 14 will swing between its base end and tip end and come into contact with the vehicle 1.

[0075] When the second winding portion 24 is wound around the branch wire portion 14 excluding the support locations 14a and 14b, the second winding portion 24 can prevent the branch wire portion 14 from coming into direct contact with the vehicle 1. This allows the second winding portion 24 to protect the branch wire portion 14 from the vehicle 1. Furthermore, if the second winding portion 24 is softer than the surface of the branch wire portion 14, rattle noise caused by contact between the branch wire portion 14 and the vehicle 1 can be suppressed.

[0076] Considering that the base end and tip end of the branch wire portion 14 are support points 14a, 14b, it is preferable that the second winding portion 24 be wound between the base end and tip end of the branch wire portion 14. The second winding portion 24 may be more likely to move toward the center between the base end and tip end, making it more likely to come into contact with the vehicle 1. For this reason, it is preferable that the second winding portion 24 be provided near the center of the branch wire portion 14. For example, the second winding portion 24 may be provided in a central, equal-divided region when the branch wire portion 14 is divided into thirds, or in a central, equal-divided region when the branch wire portion 14 is divided into fifths. For example, the second winding portion 24 may be provided in the longitudinal center of the branch wire portion 14.

[0077] Furthermore, if the second winding portion 24 is provided at a position away from the tip of the branch wire portion 14, it is easy to grasp the area of ​​the branch wire portion 14 that is closer to the tip than the second winding portion 24 and separate it from the main wire portion 13.

[0078] An example of the work of converting the packaged wire harness 10P into the wired wire harness 10W and assembling it into the vehicle 1 will be described.

[0079] As described above, in the packaged wire harness 10P, the branch wire portions 14 are temporarily fixed to the trunk wire portion 13 by the temporary fixing tape 20. Therefore, the branch wire portions 14 are held in a fixed position relative to the trunk wire portion 13. Therefore, even if the trunk wire portion 13 is bent or rolled into a compact shape, the branch wire portions 14 are unlikely to become entangled or caught on other parts of the wire harness 10.

[0080] As shown in Fig. 6, the packaged wire harness 10P is brought near an assembly target inside the vehicle 1, and the connecting portion 26 is severed. For example, a portion of the branch wire portion 14 that is distal to the connecting portion 26 is grasped with the worker's hand H, and the branch wire portion 14 is pulled in a direction away from the trunk wire portion 13. As a result, the second winding portion 24 is pulled away from the first winding portion 22, and the connecting portion 26 is severed. The connecting portion 26 is severed along the breaking portion 26L.

[0081] Branch line 14 is moved in a direction away from trunk line 13. Connector 12B at the tip of branch line 14 is connected to electrical component 16B as a connection target.

[0082] The other connectors 12A, 12C may be connected to the electrical components 16A, 16C either before or after the link 26 is severed.

[0083] As described above, the packaged wire harness 10P is changed into the wired wire harness 10W by cutting the connecting portion 26.

[0084] In the wiring-type wire harness 10W, a part of the temporary fixing tape 20 remains on the trunk portion 13 as the first path portion as a first temporary fixing tape remaining portion 120. The first temporary fixing tape remaining portion 120 includes the first winding portion 22 and a first connecting partial cut portion 122 extending from the first winding portion 22. The first connecting partial cut portion 122 is a portion of the connecting portion 26 that is cut off at the break processing portion 26L and remains connected to the first winding portion 22 side.

[0085] The first wrapped portion 22 of the remaining first temporary fixing tape portion 120 remains wrapped around the main wire portion 13. Furthermore, the first partially cut connecting portion 122 is in a state where two portions of the tape are surface-bonded to each other. For this reason, the remaining first temporary fixing tape portion 120 does not separate from the main wire portion 13, and is likely to remain attached to the main wire portion 13.

[0086] In the wiring-type wire harness 10W, the remaining part of the temporary fixing tape 20 remains on the branch line portion 14 as the second path portion as a second temporary fixing tape remaining part 130. The second temporary fixing tape remaining part 130 includes the second winding portion 24 and a second connecting partial cut part 132 extending from the second winding portion 24. The second connecting partial cut part 132 is a part of the connecting portion 26 that is cut off at the break processing part 26L and remains connected to the second winding portion 24 side.

[0087] The second wrapped portion 24 of the remaining second temporary fixing tape portion 130 remains wrapped around the branch wire portion 14. Furthermore, the second connecting partial cut portion 132 is in a state where two portions of the tape are surface-bonded to each other. Therefore, the remaining second temporary fixing tape portion 130 also does not separate from the branch wire portion 14 and is likely to remain attached to the branch wire portion 14.

[0088] According to the packaged wire harness 10P configured as described above, in the packaged form, the trunk portion 13 as the first path portion and the branch portion 14 as the second path portion are kept connected via the temporary fixing tape 20. This prevents the wire harness 10 from becoming tangled or from having a portion of the wire harness 10 get caught on another portion. This makes the packaged wire harness 10P easy to handle. Then, by cutting the connecting portion 26, the packaged wire harness 10P is unwound and changed into the wired wire harness 10W. At this time, in the wired form, the first winding portion 22 and a portion of the connecting portion 26 remain on the trunk portion 13 side, and the second winding portion 24 and the remaining portion of the connecting portion 26 remain on the branch portion 14. This prevents waste from being generated when the wire harness 10 is changed from the packaged form to the wired form.

[0089] Furthermore, when the breakable portion 26L is formed in the connecting portion 26, it becomes easier to stabilize the shape of the portion of the temporary fixing tape 20 that remains in the trunk portion 13 and the shape of the portion that remains in the branch portion 14. For example, the base of the connecting portion 26 on the side of the first winding portion 22 or the second winding portion 24 is less likely to tear, and the first winding portion 22 or the second winding portion 24 is less likely to tear, so each portion of the temporary fixing tape 20 can remain stably in the trunk portion 13 and the branch portion 14.

[0090] Furthermore, when the first path portion is the trunk portion 13 and the second path portion is the branch wire portion 14, there is a possibility that the branch wire portion 14, except for at least one of the support locations 14a and 14b, may swing in the vehicle 1 and come into contact with the vehicle 1. Therefore, if the second winding portion 24 is wound around the branch wire portion 14 at a position other than the support locations 14a and 14b, the branch wire portion 14 can be prevented from coming into direct contact with the vehicle 1. In other words, the first winding portion 22 and the second winding portion 24 can fulfill the role of protecting the wire harness 10. In this case, it may be possible to omit a protective member or a fixing part for the wire harness 10.

[0091] Furthermore, the portion of branch wire portion 14 between the base end and the tip end may swing and come into contact with vehicle 1. Second winding portion 24 wound between the base end and the tip end of branch wire portion 14 can prevent branch wire portion 14 from coming into direct contact with vehicle 1.

[0092] Furthermore, if the first winding portion 22 is a portion wound around the trunk wire portion 13 one or more but less than two turns, and the second winding portion 24 is a portion wound around the branch wire portion 14 one or more but less than two turns, the first winding portion 22 and the second winding portion 24 can be formed by winding the tape one or more but less than two turns. Therefore, the wire harness 10 can be easily temporarily fastened with the temporary fastening tape 20 and packed.

[0093] Furthermore, the connecting portion 26 is a portion in which the one-side connecting portion 27 connecting one first end 22e1 of the first winding portion 22 to one second end 24e1 of the second winding portion 24 and the other-side connecting portion 28 connecting the other first end 22e2 of the first winding portion 22 to the other second end 24e2 of the second winding portion 24 are adhered face-to-face, so that the wire harness 10 can be easily temporarily fastened with the temporary fastening tape 20 and packaged. Even if the connecting portion 26 is severed, different portions of the tape tend to remain adhered to each other, and the first winding portion 22 and the second winding portion 24 do not open. Therefore, the first winding portion 22 tends to remain on the trunk wire portion 13, and the second winding portion 24 tends to remain on the branch wire portion 14.

[0094] Furthermore, when the temporary fixing tape 20 is formed of a self-fusing tape, the first wrapping portion 22 and the second wrapping portion 24 formed of the self-fusing tape can easily protect the wire harness 10 .

[0095] Furthermore, in the wiring-type wire harness 10W in which the connecting portion 26 is severed, a first temporary fixing tape remaining portion 120 including the first winding portion 22 and a first connecting partial disconnection portion 122 extending from the first winding portion 22 remains in the main wire portion 13, and a second temporary fixing tape remaining portion 130 including the second winding portion 24 and a second connecting partial disconnection portion 132 extending from the second winding portion 24 and severed from the first connecting partial disconnection portion 122 remains in the branch wire portion 14. Therefore, the first temporary fixing tape remaining portion 120 and the second temporary fixing tape remaining portion 130 are likely to remain in the wire harness 10, and the generation of waste is more reliably suppressed.

[0096] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory.
