[0010] [Description of the 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 a 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 cutting the connecting portion, the packaged wire harness can be unwrapped 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, and the shape of the portion of the temporary fixing tape remaining in the first path portion and the shape of the portion remaining in the second path portion can be easily stabilized.

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

[0017] The branch wire portion, except for at least one support location, may swing around on the vehicle and come into contact with the vehicle. The second winding portion, which is wound around the branch wire portion at a location 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 packaged 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 packaged wire harness of any one of (1) to (4), the first winding portion may be a portion wound around the first path portion by one or more turns but less than two turns, and the second winding portion may be a portion wound around the second path portion by one or more turns but less than two turns.

[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 where 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 together at their surfaces.

[0023] In this case, the connecting portion is formed by bonding the surfaces of the one-side connecting portion and the other-side connecting portion together, so the wire harness can be easily temporarily fixed with temporary fixing tape and packed. Furthermore, even if the connecting portion is severed, 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.

[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 form 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 the 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 embodiments 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] [Embodiment] The following describes a packaged wire harness and a wired wire harness according to an embodiment. Fig. 1 is a schematic diagram showing a wire harness 10 wired in a vehicle 1. Fig. 2 is an explanatory diagram showing problems with 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 VV 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 include an optical fiber cable.

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

[0033] When the wire harness 10 is installed in the vehicle 1, it is deployed in accordance with the positions and wiring paths of the electrical components 16A, 16B, and 16C. 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 where they can be connected to the electrical components 16A, 16B, and 16C to which they are to be connected.

[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 deployed 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 that branches out from the main wire portion 13 at a point where a portion of the electric wires 11 included in the main wire portion 13 branches out from the remaining portion. That is, 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 possible that a plurality of branch wire portions branch off from the main wire portion. It is also possible that the branch wire portion further branches off 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 main wire portion. The first path portion and the second path portion may be two different branch wire portions branching off from the main 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 main wire portion 13 near the connector 12C is rolled up ( FIG. 2 ). In this case, if the branch wire portion 14 is free relative to the main wire portion 13, the branch wire portion 14 may approach the rolled-up portion of the main wire portion 13 (see the branch wire portion 14 indicated by the two-dot chain line in FIG. 2 ). In this case, the branch wire portion 14 may wind around the main wire portion 13 or become entangled with the main wire portion 13. Furthermore, the connector 12B may get caught on the connector 12C or on a clamp component for securing the vehicle or other exterior component attached to the main wire portion 13. Furthermore, if the main wire portion 13 has a branch wire other than the branch wire portion 14, the branch wire portion 14 may get entangled with the other branch wire.

[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, it is assumed that in the packaging form, 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 become tangled or caught on other portions 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 wired 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 .

[0049] The first winding portion 22 is a portion wound around the main wire portion 13 as a first path portion. The second winding portion 24 is a portion wound around the branch wire portion 14 as a second path portion. The connecting portion 26 is a portion that connects 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" it 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. A self-fusing tape is a tape that self-fuse, and is made of, for example, butyl rubber. A self-fusing tape can self-fuse at the contact points between self-fusing tapes. A self-fusing tape is generally 0.5 mm or more thick, which is thicker than a PVC tape. Using a self-fusing tape as the temporary fixing tape 20 also enhances the protection effect of the trunk wire portion 13 and the branch wire portion 14.

[0053] The first wound portion 22 may be a portion wound one or more times but less than two times around the trunk portion 13. The first wound portion 22 may be configured to make only one turn around the trunk portion 13, i.e., to surround the trunk portion 13 exactly once. The first wound 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 wound around the main line portion 13 or the branch line portion 14 one or more times but less than two times, the winding 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 where 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 wound 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 a first end 22e1, which is one of the pair of first end portions 22e1, 22e2, to a 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 a first end 22e2, which is the other of the pair of first end portions 22e1, 22e2, to a 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 faces facing each other and adhering 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 are opposed to each other and adhering 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, branch wire portion 14 is arranged along main wire portion 13. It is preferable to provide a gap between branch wire portion 14 and main wire portion 13.

[0063] The tape is folded back at the 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 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 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 that is located between first end 22e1 and second end 24e1 is one-side connecting portion 27, and the portion of the tape that is located between first end 22e1 and 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 trunk wire portion 13 and 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 the main wire portion 13. The two ends of the tape are overlapped so as to be in surface contact, and the portions are joined together 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 main 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 main 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 main 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 portions 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 processed to be easily broken. The breakable portion 26L is a portion of the connecting portion 26 that is processed to be easier to break 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 main wire portion 13 and the position of the second winding portion 24 on the branch wire 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 wire portion 14 to be held along the main wire portion 13.

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

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

[0075] When second winding portion 24 is wound around a portion of branch wire portion 14 excluding support locations 14a and 14b, second winding portion 24 can prevent branch wire portion 14 from coming into direct contact with vehicle 1. This allows second winding portion 24 to protect branch wire portion 14 from vehicle 1. Furthermore, if second winding portion 24 is softer than the surface of branch wire portion 14, rattling noise caused by contact between branch wire portion 14 and 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, equally divided region when the branch wire portion 14 is divided into thirds, or in a central, equally 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 second winding portion 24 is provided at a position away from the tip of branch wire portion 14, it is easy to separate branch wire portion 14 from main wire portion 13 by grasping the area of ​​branch wire portion 14 closer to the tip than second winding portion 24.

[0078] An example of work for 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 tangled 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 portion 14 is moved in a direction away from trunk line portion 13. Connector 12B at the tip of branch line portion 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, by cutting the connecting portion 26, the packaged wire harness 10P is changed into the wired wire harness 10W.

[0084] In the wiring-type wire harness 10W, a part of the temporary fixing tape 20 remains on the main line 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 breaking processed 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 breaking processed 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. For this reason, 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 state, 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 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 state, 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 state to the wired state.

[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 serve to protect 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, which is 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 main wire portion 13 one or more times but less than two times, and the second winding portion 24 is a portion wound around the branch wire portion 14 one or more times but less than two times, the first winding portion 22 and the second winding portion 24 can be formed by winding the tape one or more times but less than two times. Therefore, the wire harness 10 can be easily temporarily fastened with the temporary fastening tape 20 and packed.

[0093] Furthermore, in the connecting portion 26, the one-side connecting portion 27 connecting the first end 22e1 of the first winding portion 22 to the second end 24e1 of the second winding portion 24 and the other-side connecting portion 28 connecting the first end 22e2 of the first winding portion 22 to the second end 24e2 of the second winding portion 24 are joined together at their surfaces. This allows the wire harness 10 to 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 are likely to remain attached to each other, and the first winding portion 22 and the second winding portion 24 are not opened. Therefore, the first winding portion 22 is likely to remain on the trunk wire portion 13, and the second winding portion 24 is likely 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 disconnected 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. [Explanation of symbols]
