[0048] Hereinafter, with reference to the drawings, the wiring structure of the wire harness according to the embodiment of the present invention will be described in detail. In addition, the present invention is not limited to this embodiment. In addition, the constituent elements in the following embodiments include elements that can be easily conceived by those skilled in the art or substantially the same elements.

[0049] [Embodiment]

[0050] Refer to Figures 1 to 6 , and the embodiment will be described. This embodiment relates to the wiring structure of a wire harness. Figure 1 is an exploded perspective view of the wiring structure of the wire harness according to the embodiment, Figure 2 is a top view of the wiring structure of the wire harness according to the embodiment, Figure 3 is a perspective view of the wiring structure of the wire harness according to the embodiment, Figure 4 and Figure 5 is an exploded perspective view of the wiring structure of the wire harness according to the embodiment, Figure 6 is a diagram for explaining the deformation of the bent portion.

[0051] AsFigure 1 As shown, the wiring structure 1 of the harness involved in the embodiment has a harness 2 and a protector 3. The harness 2 connects a plurality of bus bars 110 to a connector 130. The wiring structure 1 of the harness is applicable to, for example, a battery pack 200 having a battery module 210. In this case, the harness 2 can be used as an element of the bus bar module 100.

[0052] The battery module 210 has a plurality of battery cells 220. The plurality of battery cells 220 are arranged along the first direction X. The bus bar module 100 has a plurality of bus bars 110, a housing 120, a harness 2, a connector 130, and a protector 3. The bus bar 110 can be connected to the electrodes of the battery cells 220. The bus bar 110 connects, for example, the electrodes of two adjacent battery cells 220.

[0053] The housing 120 houses a part of the plurality of bus bars 110 and the harness 2. The housing 120 is formed of, for example, an insulating synthetic resin. The housing 120 has a holding portion for holding the bus bars 110. The plurality of bus bars 110 are arranged and held by the housing 120 in the first direction X. The housing 120 is fixed to the first surface 210a of the battery module 210 in a state of holding the plurality of bus bars 110. The first surface 210a is the surface on which the electrodes of the battery cells 220 are arranged, and is, for example, a side surface of the battery module 210.

[0054] The harness 2 is, for example, a wire harness having a plurality of wires. The wires of the harness 2 are, for example, coated wires having a core wire and an insulating layer covering the core wire. The harness 2 is routed from the housing 120 to the connector 130. The harness 2 may also have a tubular outer member for housing the plurality of wires. The outer member can prevent the plurality of wires from spreading and prevent interference from peripheral components to the wires. The plurality of wires include a detection line W1 connected to the bus bar 110. In the case where the bus bar module 100 includes a thermistor, the plurality of wires may also have a detection line connected to the thermistor.

[0055] The connector 130 is connected to the end of the harness 2 and engages with a monitoring unit 230. The monitoring unit 230 can be fixed relative to the first surface 210a of the battery module 210. The monitoring unit 230 can be, for example, detachably attached to the first surface 210a of the battery module 210. The monitoring unit 230 can also be fixed to the battery module 210 by fastening members such as bolts. In this case, by removing the fastening members, the monitoring unit 230 can be detached from the battery module 210. The monitoring unit 230 is arranged side by side with the housing 120 of the bus bar module 100.

[0056] In this embodiment, the connector 130 engages with the fixed monitoring unit 230 along the first direction X. However, the engaging direction of the connector 130 with respect to the monitoring unit 230 is not limited to the first direction X.

[0057] In this specification, the direction in which the housing 120 and the monitoring unit 230 are arranged side by side is referred to as the side-by-side direction Z. The side-by-side direction Z is orthogonal to the first direction X. The side-by-side direction Z is, for example, the width direction in which the electrodes are arranged in one battery cell 220. The direction orthogonal to both the first direction X and the side-by-side direction Z is referred to as the second direction Y. The housing 120 and the monitoring unit 230 face the battery module 210 in the second direction Y.

[0058] The monitoring unit 230 is a device that monitors the state of the battery module 210. The monitoring unit 230 is connected to the bus bar 110 and the thermistor via the wire harness 2. The monitoring unit 230 has a connector corresponding to the connector 130. The connector 130 of the bus bar module 100 is inserted into the monitoring unit 230 and connected to the connector of the monitoring unit 230.

[0059] The wire harness 2 is laid between the housing 120 and the monitoring unit 230 in a substantially U-shaped bend. The protector 3 is a protective component that protects the wire harness 2. The protector 3 of the present embodiment can protect the wire harness 2 while ensuring the freedom of the wiring position and the wiring path of the wire harness 2, as described below.

[0060] As Figure 1 shown, the protector 3 includes a first protector 10, a second protector 20, and a guide member 30. The wire harness 2 has a protected portion 4 and an exposed portion 5. The protected portion 4 is the portion protected by the protector 3. The exposed portion 5 is the portion that protrudes from the protector 3 and is exposed to the external space.

[0061] The protected portion 4 has a first portion 41 and a second portion 42. The first portion 41 is housed in the first protector 10 of the protector 3 and is protected by the first protector 10. The second portion 42 is housed in the second protector 20 of the protector 3 and is protected by the second protector 20.

[0062] The exposed portion 5 has a first exposed portion 51, a second exposed portion 52, and a third exposed portion 53. The first exposed portion 51 protrudes from the first protector 10 toward the bus bar 110. The first exposed portion 51 is the portion of the wire harness 2 that extends between the first protector 10 and the housing 120. The second exposed portion 52 protrudes from the second protector 20 toward the connector 130. The second exposed portion 52 is the portion that extends between the second protector 20 and the connector 130. The third exposed portion 53 is exposed to the external space between the first protector 10 and the second protector 20. The third exposed portion 53 is bent in a substantially U shape and extends from the first protector 10 to the second protector 20.

[0063] The first protector 10 and the second protector 20 are formed of an insulating synthetic resin, for example. The first protector 10 is formed in a cylindrical shape. The shape of the exemplary first protector 10 is a square cylindrical shape. The outer side surface of the first protector 10 has two protrusions 11. The two protrusions 11 are arranged along the axial direction of the first protector 10. The shape of the protrusion 11 is, for example, a cylindrical shape with a widened end.

[0064] The second protector 20 is formed in a cylindrical shape. The shape of the exemplary second protector 20 is a square cylindrical shape. The outer side surface of the second protector 20 has one protrusion 21. The shape of the protrusion 21 is, for example, a cylindrical shape with a widened end.

[0065] The guiding member 30 is formed of synthetic resin, metal, etc., for example. The guiding member 30 has a main body 31, two engaging holes 32, one guiding hole 33, and an engaging portion 34. The main body 31 has a flat plate shape. The shape of the main body 31 in plan view is, for example, a rectangle.

[0066] The engaging holes 32 and the guiding hole 33 are through holes penetrating the main body 31. The engaging holes 32 correspond to the protrusions 11 of the first protector 10. The engaging holes 32 are disposed at the ends in the length direction of the main body 31. The two engaging holes 32 are arranged in a direction orthogonal to the length direction of the main body 31. The shape of the engaging holes 32 is, for example, circular. The guiding hole 33 is a long hole extending along the length direction of the main body 31. The guiding hole 33 guides the protrusion 21 of the second protector 20.

[0067] The engaging portion 34 engages with the wall portion of the device or the like. The engaging portion 34 is, for example, fitted into a recess provided in the frame of the battery pack 200. The engaging portion 34 is disposed at the end of the main body 31 on the side opposite to the side of the engaging holes 32. The guiding hole 33 extends between the engaging portion 34 and the engaging holes 32.

[0068] As Figure 1 shown, the portion of the wire harness 2 between the housing 120 and the connector 130 is inserted into the first protector 10 and the second protector 20. The second protector 20 is disposed on the connector 130 side with respect to the first protector 10. In other words, the second portion 42 protected by the second protector 20 is closer to the connector 130 than the first portion 41 protected by the first protector 10. The two protrusions 11 of the first protector 10 are inserted into the corresponding engaging holes 32 of the guiding member 30. By fitting the two protrusions 11 into the two engaging holes 32, the first protector 10 is fixed to the guiding member 30.

[0069] The protrusion 21 of the second protector 20 is inserted into the guiding hole 33 of the guiding member 30 and is guided by the guiding hole 33. The guiding member 30 assembled to the two protectors 10, 20 is connected to the wall portion or the like through the engaging portion 34. The engaging portion 34 may be supported by the wall portion or the like in such a manner that the main body 31 can swing.

[0070] The first protector 10 and the second protector 20 of the present embodiment are arranged on the second surface 210b of the battery module 210. The second surface 210b is a surface different from the first surface 210a and is a surface orthogonal to the first surface 210a. The second surface 210b is, for example, the end surface in the first direction X of the battery module 210.

[0071] The first protector 10 and the second protector 20 extend along the second surface 210b in the second direction Y. In addition, the two protectors 10 and 20 are arranged side by side in the side-by-side direction Z. The first exposed portion 51 protrudes from the first protector 10 toward the second direction Y. The second exposed portion 52 protrudes from the second protector 20 toward the second direction Y. The first exposed portion 51 and the second exposed portion 52 are arranged side by side in the side-by-side direction Z and face each other in the side-by-side direction Z. That is, the protector 3 houses the protected portion 4 in such a manner that the first exposed portion 51 and the second exposed portion 52 extend side by side.

[0072] The first exposed portion 51 is disposed while being bent along one side of the corner where the first surface 210a and the second surface 210b intersect. The second exposed portion 52 is disposed while being bent along the above-mentioned corner.

[0073] As Figure 2 shown, the first protector 10 is held by the guide member 30. The first protector 10 is fixed at a prescribed position in the side-by-side direction Z. The second protector 20 can move in the side-by-side direction Z while being guided by the guide member 30. The second protector 20 relatively moves with respect to the first protector 10 while sliding the protrusion 21 along the guide hole 33. The guide hole 33 enables the protrusion 21 to move to the first side Z1 in the side-by-side direction Z and enables the protrusion 21 to move to the second side Z2 in the side-by-side direction Z. The first side Z1 is the side where the second protector 20 is away from the first protector 10. The second side Z2 is the side where the second protector 20 approaches the first protector 10.

[0074] By moving the second protector 20, the interval Dt between the first exposed portion 51 and the second exposed portion 52 changes. That is, the protector 3 is configured to be able to change the interval Dt between the first exposed portion 51 and the second exposed portion 52.

[0075] Since the interval Dt is variable, the wiring harness 2 can change the wiring position and the wiring path according to the position of the connector 130 in the side-by-side direction Z. For example, the protector 3 can cope with a plurality of battery modules 210 having different relative positions of the monitoring unit 230 with respect to the housing 120 in the side-by-side direction Z. That is, according to the wiring structure 1 of the wiring harness according to the present embodiment, even when the relative position of the monitoring unit 230 with respect to the housing 120 is different in the side-by-side direction Z, the connector 130 can be fitted to the monitoring unit 230.

[0076] In addition, according to the wiring structure 1 of the wiring harness according to the present embodiment, the connector 130 can be fitted to the monitoring unit 230 that is not fixed to the battery module 210. For example, after the connector 130 is fitted to the monitoring unit 230, the monitoring unit 230 can be fixed to the battery module 210. The wiring structure 1 of the wiring harness can also be configured to be able to fit the connector 130 to the monitoring unit 230 outside the battery pack 200, for example.

[0077] The movable range of the second exposed portion 52 in the side-by-side direction Z can be set according to the length and position of the guide hole 33. The length of the third exposed portion 53 can include a surplus length that allows the second protector 20 to move along the guide hole 33.

[0078] In Figure 3 the other protector 3 according to the embodiment is shown. Figure 3 the protector 3 of Figure 1 has a housing portion 60 instead of the guide member 30 of the protector 3 of Figure 3 The housing portion 60 of

[0079] is a groove member having a groove shape. The housing portion 60 allows the first protector 10 and the second protector 20 to move relative to each other in the side-by-side direction Z.

[0080] The first side wall 61 is disposed on the second surface 210b of the battery module 210. The second side wall 62 is disposed at an interval from the first side wall 61. The size of the gap between the first side wall 61 and the second side wall 62 is such that the first protector 10 and the second protector 20 are opposed to each other in the side-by-side direction Z and allows relative movement of the two protectors 10, 20.

[0081] The bottom wall 63 connects the ends of the first side wall 61 and the second side wall 62 on the second side Z2. The end of the housing portion 60 on the first side Z1 is open toward the first side Z1. That is, the first side wall 61, the second side wall 62, and the bottom wall 63 form a substantially U-shaped groove that opens toward the first side Z1.

[0082] The first protector 10 and the second protector 20 are housed in the housing space 64 between the first side wall 61 and the second side wall 62. The first protector 10 and the second protector 20 are formed in a cylindrical shape. The shapes of the two protectors 10, 20 are, for example, square cylindrical shapes. In this case, one side surface of the first protector 10 and the second protector 20 faces the first side wall 61, and the other side surface faces the second side wall 62. Minute gaps are provided between the two protectors 10, 20 and the two side walls 61, 62. The two protectors 10, 20 can move along the juxtaposed direction Z while sliding relative to the two side walls 61, 62.

[0083] In Figure 3 the protector 3, the first protector 10 does not have the protrusion 11, and the second protector 20 does not have the protrusion 21. In the two protectors 10, 20, the opposing surfaces facing the side walls 61, 62 may be flat surfaces. The opposing surfaces of the protectors 10, 20 may also have ribs that reduce the contact area with the side walls 61, 62. The side walls 61, 62 may also have ribs that reduce the contact area with the protectors 10, 20. The side walls 61, 62 may also have ribs that guide the protectors 10, 20. In this case, the guide ribs may extend along the juxtaposed direction Z.

[0084] The first protector 10 and the second protector 20 extend in the second direction Y and are juxtaposed in the juxtaposed direction Z in the housing portion 60. The first protector 10 houses the first part 41 of the protected portion 4. The second protector 20 houses the second part 42 of the protected portion 4. The first exposed portion 51 protrudes from the first protector 10 toward the second direction Y. The second exposed portion 52 protrudes from the second protector 20 toward the second direction Y. The first exposed portion 51 and the second exposed portion 52 are juxtaposed in the juxtaposed direction Z and face each other in the juxtaposed direction Z. That is, Figure 3 the protector 3 causes the first exposed portion 51 and the second exposed portion 52 to extend side by side.

[0085] The bottom wall 63 can support the first protector 10. For example, when the juxtaposed direction Z is the vertical direction and the second side Z2 is the lower side, the bottom wall 63 can support the first protector 10 from below.

[0086] The first protector 10 and the second protector 20 can move along the juxtaposed direction Z inside the housing portion 60. The first side wall 61 and the second side wall 62 guide the protectors 10, 20 and allow the protectors 10, 20 to move along the juxtaposed direction Z. Therefore, Figure 3 the protector 3 is configured to be able to change the interval Dt between the first exposed portion 51 and the second exposed portion 52. The two protectors 10, 20 can move in the juxtaposed direction Z, so that the connector 130 has high followability with respect to the monitoring unit 230.

[0087] InFigure 4 Other protectors 3 related to the embodiment are shown. Figure 4 The protector 3 has a protector main body 71 and a cover 72. The protector main body 71 is disposed on the second surface 210b of the battery module 210. The monitoring unit 230 and the housing 120 are disposed on the first surface 210a of the battery module 210. The protector main body 71 has a bottom wall 73, a first side wall 74a, a second side wall 74b, a third side wall 74c, and a partition wall 75. Figure 4 The shape of the illustrated bottom wall 73 is substantially rectangular.

[0088] The first side wall 74a, the second side wall 74b, and the third side wall 74c stand up from the edge of the bottom wall 73 toward the first direction X. The first side wall 74a and the second side wall 74b face each other in the side-by-side direction Z. The third side wall 74c connects the ends of the first side wall 74a and the second side wall 74b in the second direction Y and extends in the side-by-side direction Z. The bottom wall 73 and the three side walls 74a, 74b, 74c form a housing space 77 for housing the protected portion 4.

[0089] Engaging portions 76 are respectively provided on the side walls 74a, 74b, 74c. The partition wall 75 projects from the bottom wall 73 toward the first direction X and extends in the second direction Y. A gap through which the protected portion 4 can pass is provided between the end of the partition wall 75 and the third side wall 74c. The partition wall 75 divides the interior of the housing space 77 into a first space portion 77a and a second space portion 77b. The first space portion 77a is the space portion located on the second side Z2 with respect to the partition wall 75. The second space portion 77b is the space portion located on the first side Z1 with respect to the partition wall 75.

[0090] The protected portion 4 is bent into a substantially U shape so as to be wound around the partition wall 75 and housed in the housing space 77. The protected portion 4 has a first extension portion 43 and a second extension portion 44. The first extension portion 43 is the portion extending in the first space portion 77a. The second extension portion 44 is the portion extending in the second space portion 77b. In the side-by-side direction Z, the width of the second space portion 77b is wider than the width of the first space portion 77a. That is, the movable region of the second extension portion 44 in the side-by-side direction Z is wider than the movable region of the first extension portion 43.

[0091] The cover 72 is engaged with the protector main body 71 along the first direction X and covers the housing space 77. The cover 72 has a plate shape, covers the housing space 77 from the first direction X, and faces the bottom wall 73. A plurality of engaging portions 78 are provided at the edge of the cover 72. The engaging portion 78 is engaged with the engaging portion 76 of the protector main body 71.

[0092] The first exposed portion 51 protrudes from the first space portion 77a toward the second direction Y. That is, the first exposed portion 51 extends between the first extension portion 43 and the housing 120. The second exposed portion 52 protrudes from the second space portion 77b toward the second direction Y. That is, the second exposed portion 52 extends between the second extension portion 44 and the connector 130. The first exposed portion 51 and the second exposed portion 52 are arranged side by side in the side-by-side direction Z and face each other in the side-by-side direction Z. That is, Figure 4 The protector 3 of Figure 4 houses the protected portion 4 in such a manner that the first exposed portion 51 and the second exposed portion 52 extend side by side.

[0093] Figure 4 The protector 3 of Figure 4 allows the protected portion 4 to deform in the accommodation space 77. For example, the protector 3 allows the protected portion 4 to deform in the accommodation space 77 in a manner following the change in the interval Dt between the first exposed portion 51 and the second exposed portion 52. The interval Dt between the two exposed portions 51, 52 changes, for example, when the connector 130 is fitted to the monitoring unit 230. Figure 4 The protector 3 of Figure 4 can allow the deformation of the wire harness 2 so that the connector 130 can be fitted to the monitoring unit 230 at different positions in the side-by-side direction Z.

[0094] In addition, according to Figure 4 the protector 3 of Figure 4 , the monitoring unit 230 can be fixed to the battery module 210 after the connector 130 is fitted to the monitoring unit 230. The protector 3 can also be configured, for example, to be able to fit the connector 130 to the monitoring unit 230 outside the battery pack 200.

[0095] In Figure 5 Figure 5 shows another protector 3 according to the embodiment. Figure 5 The protector 3 of Figure 5 has a protector main body 81 and a cover 82. The protector main body 81 is disposed on the second surface 210b of the battery module 210. The monitoring unit 230 and the housing 120 are disposed on the first surface 210a of the battery module 210. The protector main body 81 has a bottom wall 83, a first side wall 84a, a second side wall 84b, and a third side wall 84c. Figure 5 The bottom wall 83 shown in Figure 5 has a tapered shape. More specifically, the shape of the bottom wall 83 in plan view is a tapered shape with the largest opening width from which the two exposed portions 51, 52 protrude. The shape of the bottom wall 83 is, for example, a substantially V-shaped.

[0096] The first side wall 84a, the second side wall 84b, and the third side wall 84c stand up from the edge of the bottom wall 83 toward the first direction X. The first side wall 84a and the second side wall 84b face each other in the juxtaposed direction Z. The third side wall 84c connects the ends of the first side wall 84a and the second side wall 84b in the second direction Y and extends in the juxtaposed direction Z. The bottom wall 83 and the three side walls 84a, 84b, 84c form a housing space 87 for housing the protected portion 4. The interval between the two side walls 84a, 84b widens as it moves away from the third side wall 84c along the second direction Y. Engagement portions 86 are provided on the side walls 84a, 84b, 84c respectively.

[0097] The protected portion 4 is housed in the housing space 87 while being bent into a substantially U shape or while being bent into a substantially V shape. In the case where the wire harness 2 is composed of a plurality of electric wires, the protected portion 4 may also be housed in the housing space 87 while being bent into a substantially U shape. Figure 5 The illustrated wire harness 2 is a flat wiring component such as a flexible printed circuit board. The flat wiring component can be housed in the housing space 87 while being bent into a substantially V shape.

[0098] In Figure 5 the wire harness 2, the protected portion 4 has a first bent portion 45 and a second bent portion 46. The first bent portion 45 is the bent portion closer to the first exposed portion 51 among the two bent portions 45, 46. The second bent portion 46 is the bent portion closer to the second exposed portion 52 among the two bent portions 45, 46.

[0099] The cover 82 engages with the protector main body 81 along the first direction X and covers the housing space 87. The cover 82 has a plate shape, covers the housing space 87 from the first direction X, and faces the bottom wall 83. A plurality of engagement portions 88 are provided at the edge of the cover 82. The engagement portion 88 engages with the engagement portion 86 of the protector main body 81.

[0100] The first exposed portion 51 and the second exposed portion 52 project from the housing space 87 toward the second direction Y. The first exposed portion 51 and the second exposed portion 52 are arranged in the juxtaposed direction Z and face each other in the juxtaposed direction Z. That is, Figure 5 the protector 3 houses the protected portion 4 in such a manner that the first exposed portion 51 and the second exposed portion 52 extend side by side.

[0101] Figure 5 the protector 3 allows the protected portion 4 to deform in the housing space 87. For example, the protector 3 allows the protected portion 4 to deform in the housing space 87 in a manner that follows the change in the interval Dt between the first exposed portion 51 and the second exposed portion 52. Figure 6The deformation of the second bent portion 46 is shown. The second bent portion 46 is folded back between the first portion 46a and the second portion 46b. The first portion 46a is the portion connected to the first bent portion 45. The second portion 46b is the portion connected to the second exposed portion 52.

[0102] The protected portion 4 is deformed in such a way that the angle θ of the second bent portion 46 increases or decreases. The angle θ is the angle formed by the extending direction of the first portion 46a and the extending direction of the second portion 46b. On Figure 6 the left side of, the second bent portion 46 when the angle θ is a relatively small value θ1 is shown, and on Figure 6 the right side of, the second bent portion 46 when the angle θ is a relatively large value θ2 is shown.

[0103] When the second exposed portion 52 approaches the first exposed portion 51 along the side-by-side direction Z, the protected portion 4 is deformed in such a way that the angle θ decreases. On the other hand, when the second exposed portion 52 moves away from the first exposed portion 51 along the side-by-side direction Z, the protected portion 4 is deformed in such a way that the angle θ increases.

[0104] In addition, when the interval Dt between the first exposed portion 51 and the second exposed portion 52 increases or decreases, the protected portion 4 can also change the interval between the two bent portions 45 and 46. For example, when the second exposed portion 52 approaches the first exposed portion 51 along the side-by-side direction Z, the protected portion 4 can also be deformed in such a way as to widen the interval between the two bent portions 45 and 46. For example, when the second exposed portion 52 moves away from the first exposed portion 51 along the side-by-side direction Z, the protected portion 4 can also be deformed in such a way as to narrow the interval between the two bent portions 45 and 46.

[0105] In this way, Figure 5 the protector 3 allows the protected portion 4 to be deformed in the accommodation space 87 in such a way as to follow the change in the interval Dt between the first exposed portion 51 and the second exposed portion 52. The interval Dt between the two exposed portions 51 and 52 changes, for example, when the connector 130 is engaged with the monitoring unit 230. Figure 5 The protector 3 can allow the deformation of the wire harness 2, so that the connector 130 can be engaged with the monitoring unit 230 at different positions in the side-by-side direction Z.

[0106] In addition, according to Figure 5 the protector 3, after the connector 130 is engaged with the monitoring unit 230, the monitoring unit 230 can be fixed to the battery module 210. The wiring structure 1 of the wire harness can also be configured, for example, to be able to engage the connector 130 with the monitoring unit 230 outside the battery pack 200.

[0107] As described above, the wiring structure 1 of the wiring harness according to the present embodiment includes a wiring harness 2 and a protector 3. The wiring harness 2 includes a detection line W1 that connects the bus bar 110 and the connector 130. The wiring harness 2 has a protected portion 4 protected by the protector 3, a first exposed portion 51, and a second exposed portion 52. The first exposed portion 51 protrudes from the protector 3 toward the bus bar 110. The second exposed portion 52 protrudes from the protector 3 toward the connector 130.

[0108] The protector 3 houses the protected portion 4 in such a manner that the first exposed portion 51 and the second exposed portion 52 extend side by side. The protector 3 is configured to be able to change the interval Dt between the first exposed portion 51 and the second exposed portion 52. The wiring structure 1 of the wiring harness according to the present embodiment can change the interval Dt between the first exposed portion 51 and the second exposed portion 52, and can improve the workability when the connector 130 is engaged with the mating connector.

[0109] Figure 1 The protector 3 includes a first protector 10, a second protector 20, and a guide member 30. The first protector 10 houses a portion of the protected portion 4 that is connected to the first exposed portion 51. The second protector 20 houses a portion of the protected portion 4 that is connected to the second exposed portion 52. The guide member 30 guides the first protector 10 and the second protector 20 so that the first protector 10 and the second protector 20 can move relative to each other in the side-by-side direction Z. With such a structure, the trajectories of the relative movement of the two protectors 10 and 20 can be controlled.

[0110] Figure 3 The protector 3 includes a first protector 10, a second protector 20, and a housing portion 60. The first protector 10 houses a portion of the protected portion 4 that is connected to the first exposed portion 51. The second protector 20 houses a portion of the protected portion 4 that is connected to the second exposed portion 52. The housing portion 60 houses the first protector 10 and the second protector 20 so that the first protector 10 and the second protector 20 move relative to each other in the side-by-side direction Z.

[0111] Figure 4 The protector 3 has a housing space 77 for housing the protected portion 4. The protector 3 allows the protected portion 4 to deform in the housing space 77 in such a manner as to follow the change in the interval Dt between the first exposed portion 51 and the second exposed portion 52. Similarly, Figure 5 The protector 3 has a housing space 87 for housing the protected portion 4. The protector 3 allows the protected portion 4 to deform in the housing space 87 in such a manner as to follow the change in the interval Dt between the first exposed portion 51 and the second exposed portion 52. The protected portion 4 deforms inside the housing spaces 77 and 87, so that the wiring harness 2 is less likely to interfere with surrounding components.

[0112] In addition, the shape of the protected portion 4 in the accommodation spaces 77 and 78 is not limited to a U shape or a V shape. The protected portion 4 may, for example, have a meandering shape including a plurality of bent portions, or may have other shapes. The protected portion 4 may also have a plurality of bent portions in the accommodation spaces 77 and 78. The extending direction of the protected portion 4 changes at each bent portion. The shape of each bent portion may be a U shape or a V shape.

[0113] The contents disclosed in the above-described embodiments can be appropriately combined and implemented.
