Best Mode for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wire harness of the present disclosure is as follows.

[0011] (1) A connector for equipment connected to a connector of equipment, a connector for a first harness connected to a connector of a first counterpart wire harness, a connector for a second harness connected to a connector of a second counterpart wire harness, a first wiring for equipment connecting the connector for equipment and the connector for the first harness, a second wiring for equipment connecting the connector for equipment and the connector for the second harness, and a flat base member holding the first wiring for equipment and the second wiring for equipment. The first counterpart wire harness and the second counterpart wire harness are collectively connected to the equipment via the connector for equipment. Thereby, compared with the case where the first counterpart wire harness and the second counterpart wire harness are individually connected to the equipment, the number of connectors of the equipment can be reduced, and the equipment to which the wire harness is connected can be miniaturized. Further, since the first wiring for equipment and the second wiring for equipment are held by the flat base member, the intermediate wiring portion becomes flat, and the wire harness can be thinned.

[0012] (2) In the wire harness of (1), the distance between the first harness connector and the second harness connector may be shorter than either the distance between the device connector and the first harness connector or the distance between the device connector and the second harness connector. As a result, the first harness connector and the second harness connector can be arranged close to each other, facilitating the connection operation between the wire harness and the first mating wire harness and the second mating wire harness. Also, the first mating wire harness and the second mating wire harness can be easily connected to a remote device via the wire harness.

[0013] (3) In the wire harness of (2), the base member includes a first strip portion and a second strip portion longer than the first strip portion. The base end portion of the second strip portion extends in a direction intersecting the first strip portion from the middle portion of the first strip portion. The first harness connector is provided at one end of the first strip portion, the second harness connector is provided at the other end of the first strip portion, and the device connector is provided at the tip end portion of the second strip portion. The first device wiring may extend from the one end of the first strip portion toward the tip end of the second strip portion, and the second device wiring may extend from the other end of the first strip portion toward the tip end of the second strip portion. Thereby, the wire harness is easily connected to the first mating wire harness and the second mating wire harness extending from opposite sides.

[0014] (4) In the wire harness according to any one of (1) to (3), it may not be provided with a wiring for connecting the first harness connector and the second harness connector. As a result, since the wire harness does not connect the first mating wire harness and the second mating wire harness, the wire harness is simplified.

[0015] (5) In any one of the wire harnesses (1) to (4), the lengths of the wiring for the first device and the wiring for the second device may each be within 1 meter. Thereby, the wire harness can connect the device and the counterpart wire harness in a narrow area in the vehicle.

[0016] (6) In any one of the wire harnesses (1) to (5), the arrangement area in the vehicle is the rear area, the first harness connector may be a connector for the floor harness, and the second harness connector may be a connector for the rear harness. Thereby, in the rear area of the vehicle, the floor harness and the rear harness are connected to the device via the wire harness.

[0017] [Details of Embodiments of the Present Disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0018] [Embodiment 1] Hereinafter, the wire harness according to Embodiment 1 will be described. FIG. 1 is an explanatory diagram showing a wiring system 100 including a wire harness 30 in a vehicle 10. FIG. 2 is a plan view showing the wire harness 30 according to Embodiment 1. FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2. FIG. 4 is a perspective view showing a state where the wire harness 30 is arranged in the vehicle 10.

[0019] The wire harness 30 is arranged in the vehicle 10, for example. A plurality of counterpart wire harnesses 20 and devices 22 are also arranged in the vehicle 10. The wire harness 30 connects the plurality of counterpart wire harnesses 20 to the device 22. The wire harness 30 and the plurality of counterpart wire harnesses 20 are incorporated into the wiring system 100 of the vehicle 10. First, the wiring system 100 and the arrangement area of the wire harness 30 in the vehicle 10 will be described first.

[0020] <Wiring System 100> The wiring system 100 includes a wire harness 30 and a plurality of counterpart wire harnesses 20. The plurality of counterpart wire harnesses 20 are arranged in different areas from each other in the vehicle 10. The wire harness 30 is interposed between the plurality of counterpart wire harnesses 20 and the device 22, and connects each of the plurality of counterpart wire harnesses 20 and the device 22.

[0021] The arrangement area of the wire harness 30 in the vehicle 10 is an area corresponding to the arrangement areas of the plurality of counterpart wire harnesses 20. In view of the wire harness 30 being interposed between the plurality of counterpart wire harnesses 20, the arrangement area of the wire harness 30 is preferably an area close to the boundaries of the plurality of areas where the plurality of counterpart wire harnesses 20 are respectively arranged. For example, the arrangement area of the wire harness 30 is located between the areas where the plurality of counterpart wire harnesses 20 are arranged. Examples of the counterpart wire harness 20 include an engine room harness 20A, an instrument panel harness 20B, a door harness 20C, a floor harness 20D, a rear harness 20E, and the like. The engine room harness 20A is arranged in the engine room. The instrument panel harness 20B is arranged to extend along the instrument panel reinforcement 17. The door harness 20C is arranged on the door. The floor harness 20D is arranged along the floor panel 18. The rear harness 20E is arranged in an area behind the floor harness 20D. The rear harness 20E is connected to loads such as a rear lamp and a rear wiper, for example.

[0022] Note that in the present disclosure, the term "engine room" is a convenient name for the front compartment located in front of the passenger compartment, and it is not necessarily required that an engine be arranged in the engine room. Similarly, in the present disclosure, the term "engine room harness 20A" is a convenient name for the counterpart wire harness 20 arranged in the front compartment located in front of the passenger compartment.

[0023] The wiring system 100 further includes a wire harness 130 disposed in an area different from the wire harness 30. The wire harness 130 is interposed between a plurality of counterpart wire harnesses 20 and the device 122 to connect each of the plurality of counterpart wire harnesses 20 and the device 122. In the present embodiment, the wire harness 30 will be described, and the wire harness 130 will be described in Embodiment 2.

[0024] Here, the arrangement area of the wire harness 30 in the vehicle 10 is the rear area. Specifically, it is an area in the rear area that is close to the rear seat (for example, under the rear seat, behind, etc.) or an area such as the rear luggage. In FIG. 4, the case where the wire harness 30 is disposed at a position close to the rear seat is shown by a solid line, and the case where it is disposed in the rear luggage is shown by a two-dot chain line. When the arrangement area of the wire harness 30 is the rear area, the floor harness 20D and the rear harness 20E are assumed as the counterpart wire harnesses 20. For example, a rocker portion 18a is located at the side edge of the floor panel 18 in the vehicle. The end portion of the floor harness 20D that is connected to the wire harness 30 extends in the longitudinal direction of the vehicle along the rocker portion 18a.

[0025] In the present disclosure, when the arrangement areas of a plurality of counterpart wire harnesses 20, such as the floor harness 20D and the rear harness 20E, are divided in the longitudinal direction of the vehicle 10, the counterpart wire harness 20 disposed forward among the plurality of counterpart wire harnesses 20 may be referred to as the front harness. Also, the counterpart wire harness 20 disposed rearward of the front harness among the plurality of counterpart wire harnesses 20 may be referred to as the rear harness.

[0026] The arrangement area of the wire harness 30 is, for example, an area that is not easily accessible to the passengers during normal use of the vehicle 10. The device 22 is disposed in the same area as the arrangement area of the wire harness 30. The device 22 is an electrical device that is not operated by the passengers during normal use of the vehicle 10.

[0027] The device 22 is, for example, an ECU (Electronic Control Unit). In the vehicle 10, one central ECU and a plurality of zone ECUs may be provided. The zone ECUs are provided for each of a plurality of zones into which the vehicle 10 is divided. The zone ECU mainly performs control of the devices 22 existing within that zone. The central ECU coordinates the plurality of zone ECUs to realize control that collaborates throughout the vehicle 10. The device 22 may be, for example, a zone ECU. In this case, the control targets of the device 22 as the zone ECU are a plurality of devices such as the connection destinations of the floor harness 20D and the rear harness 20E.

[0028] However, the device 22 that is an ECU may be a general ECU other than the zone ECU. Also, the device 22 does not have to be an ECU, and may be, for example, a junction block (also referred to as an electrical connection box) or the like.

[0029] <Wire harness 30> The wire harness 30 includes a plurality of types of connectors 40, a plurality of wirings 50, and a base member 56.

[0030] The plurality of types of connectors 40 have mutually different connection destinations. The plurality of types of connectors 40 include a device connector 42 and a harness connector 44. The device connector 42 is connected to the connector 40 of the device 22. The harness connector 44 has a first harness connector 44X and a second harness connector 44Y. The first harness connector 44X is connected to the connector of the first counterpart wire harness 20X. The second harness connector 44Y is connected to the connector of the second counterpart wire harness 20Y.

[0031] In the example shown in FIG. 2, the various connectors 40 are one type of connector. That is, the device connector 42, the first harness connector 44X, and the second harness connector 44Y are each one type of connector. In the present disclosure, even for two or more connectors, if the connection destinations are the same, they shall be regarded as one type of connector. In other words, regardless of the number of connectors connected to the same device 22 or the same counterpart wire harness 20, they shall be regarded as one type of connector. Viewed another way, each of the plurality of types of connectors 40 may consist of one or more connectors (hereinafter sometimes referred to as split connectors). Each connector may include connectors having the same structure. Here, even if connectors have the same structure, if the connection destinations are different, they shall be regarded as different types of connectors.

[0032] At least one of the plurality of types of connectors 40 may have two or more split connectors. For example, the connector 40 with the largest number of poles among the plurality of types of connectors 40 (for example, the device connector 42) may have two or more split connectors. This facilitates the manufacture of the connector 40 with the largest number of poles among the plurality of types of connectors 40.

[0033] When the connector 40 includes a plurality of split connectors, it is preferable that the number of the plurality of types of connectors 40 is four or more and the number of split connectors is N or less. However, N is the number obtained by subtracting 2 from the number of types of the plurality of types of connectors 40 in the wire harness 30. This can reduce the number of sets of connectors to be fitted compared with the case where other types of connectors 40 are respectively connected to the connection counterpart of a certain type of connector 40. Specifically, here, the connectors 40 in the wire harness 30 are three types, namely the device connector 42, the first harness connector 44X, and the second harness connector 44Y. Therefore, it is preferable that the connectors 40 in the wire harness 30 do not include a plurality of split connectors.

[0034] Each connector 40 includes, for example, a connector terminal and a connector housing. The connector terminal is electrically connected to the end of the wiring 50. When the connector 40 is connected to the mating connector, the wiring 50 is electrically connected to the mating conductor via the connector terminal. The connector housing has insulation. The connector housing holds the connector terminals in a predetermined arrangement.

[0035] The plurality of wirings 50 includes a plurality of device wirings 51. The plurality of device wirings 51 has a first device wiring 51X and a second device wiring 51Y. The first device wiring 51X connects the device connector 42 and the first harness connector 44X. The second device wiring 51Y connects the device connector 42 and the second harness connector 44Y.

[0036] Here, only one device connector 42 is provided. A plurality of device connectors 42 may be provided. Also, the harness connectors 44 have only two, namely the first harness connector 44X and the second harness connector 44Y. Three or more harness connectors 44 may be provided. Also, the plurality of wirings 50 includes only the plurality of device wirings 51. The plurality of wirings 50 may include a wiring other than the device wiring 51. The plurality of device wirings 51 has only the first device wiring 51X and the second device wiring 51Y. The plurality of device wirings 51 may have a device wiring other than the first device wiring 51X and the second device wiring 51Y.

[0037] Here, the first mating wire harness 20X is the floor harness 20D, and the second mating wire harness 20Y is the rear harness 20E. Also, the first harness connector 44X is a connector for the floor harness 20D, and the second harness connector 44Y is a connector for the rear harness 20E. The first device wiring 51X connects the device connector 42 and the floor harness connector 44X. The second device wiring 51Y connects the device connector 42 and the rear harness connector 44Y.

[0038] Here, as the wiring 50, an electric wire 54 is provided. The electric wire 54 is a covered electric wire. The covered electric wire has a core wire 55a and a covering layer 55b that covers the periphery of the core wire 55a. The covered electric wire may have an extruded covering layer 55b. The covered electric wire may be an enameled electric wire. The covering layer 55b is provided separately from the base member 56. However, in the wire harness 30, an FFC (Flexible Flat Cable) or an FPC (Flexible Printed Circuit board) may be provided. In this case, the covering layer may also serve as the base member. That is, a covering layer as the base member may collectively cover a plurality of bare conductors as the wiring.

[0039] The base member 56 is a flat member. The base member 56 holds the first device wiring 51X and the second device wiring 51Y. The base member 56 may be a resin member, a metal member, or a composite member having both a resin part and a metal part. The base member 56 may be a flexible sheet member. The sheet member may be a sheet having a fiber material such as a non-woven fabric. The sheet member may be a sheet having a solid cross-section. The sheet member has flexibility that can follow the bending of the electric wire 54.

[0040] A plurality of electric wires 54 are arranged side by side on the main surface of the base member 56. By fixing each electric wire 54 to the base member 56, a parallel state is maintained. The fixing mode between the electric wire 54 and the base member 56 is not particularly limited and can be set as appropriate. For example, the electric wire 54 and the base member 56 may be fixed by fusion. In this case, the resin contained in at least one of the covering of the electric wire 54 and the main surface of the base member 56 melts and adheres to the surface of the other member for fixing. Also, for example, the electric wire 54 and the base member 56 may be attached by an adhesive or an adhesive material.

[0041] In the wire harness 30, the electric wires 54 are arranged so as not to cross each other on the base member 56. Thereby, an increase in the thickness of the wire harness 30 is suppressed. However, in the wire harness 30, a crossing portion where the electric wires 54 cross each other may be provided on the base member 56.

[0042] The base member 56 includes a first strip portion 57 and a second strip portion 58. A base end portion of the second strip portion 58 extends from an intermediate portion of the first strip portion 57 in a direction intersecting the first strip portion 57. The intersection of the first strip portion 57 and the second strip portion 58 is a branch portion. The second strip portion 58 is longer than the first strip portion 57. The base member 56 is formed in a T shape.

[0043] A first harness connector 44X is provided at one end portion of the first strip portion 57. A second harness connector 44Y is provided at the other end portion of the first strip portion 57. An equipment connector 42 is provided at a tip end portion of the second strip portion 58. A first equipment wiring 51X extends from one end portion of the first strip portion 57 toward the tip end portion of the second strip portion 58. A second equipment wiring 51Y extends from the other end portion of the first strip portion 57 toward the tip end portion of the second strip portion 58. The first equipment wiring 51X and the second equipment wiring 51Y extend from the tip end portion of the second strip portion 58 toward the base end portion of the second strip portion 58, and then branch and extend along the first strip portion 57 in opposite directions to each other.

[0044] As shown by the solid line in FIG. 4, when the wire harness 30 is disposed in the vicinity of the rear seat, for example, the first strip portion 57 may be disposed along the rocker portion 18a, and the second strip portion 58 may be disposed on the main body portion of the floor panel 18. The equipment connector 42 is connected to the equipment 22 at a position close to the main body portion of the floor panel 18. The first harness connector 44X is connected to the floor harness 20D at a position close to the rocker portion 18a, and the second harness connector 44Y is connected to the rear harness 20E. Usually, the rocker portion 18a is higher than the main body portion of the floor panel 18. For this reason, the position where the harness connector 44 is connected to the counterpart wire harness 20 and the position where the equipment connector 42 is connected to the equipment 22 are separated in the vertical direction.

[0045] As shown by the two-dot chain line in FIG. 4, when the wire harness 30 is disposed in the rear luggage compartment, for example, the first strip portion 57 may be disposed along the upper portion of the portion forming the rear wheel wheel house, and the second strip portion 58 and the equipment 22 may be disposed on the side panel. The first harness connector 44X is connected to the floor harness 20D at a position close to the upper portion of the portion forming the rear wheel wheel house, and the second harness connector 44Y is connected to the rear harness 20E. In the side panel, the equipment connector 42 is connected to the equipment 22. For this reason, the position where the harness connector 44 is connected to the counterpart wire harness 20 and the position where the equipment connector 42 is connected to the equipment 22 are separated in the vertical direction.

[0046] Also, as shown in FIG. 4, the wire harness 30 may be arranged on the vehicle 10 with the base member 56 bent in the thickness direction. The bending location and the number of bends in the base member 56 are not particularly limited and can be set as appropriate. In the example shown by the solid line in FIG. 4, the wire harness 30 is arranged with the base member 56 bent twice. The two bending locations are bent in opposite directions to each other. In the example shown by the dashed-dotted line in FIG. 4, the base member 56 is bent once and arranged. The wire harness 30 may be arranged with the second belt-like portion 58 bent. The position where the harness connector 44 is connected to the mating wire harness 20 and the position where the device connector 42 is connected to the device 22 are separated in the horizontal direction (in the example shown in FIG. 4, the left-right direction).

[0047] The distance between the first harness connector 44X and the second harness connector 44Y is shorter than either the distance between the device connector 42 and the first harness connector 44X or the distance between the device connector 42 and the second harness connector 44Y. Here, the distance between the first harness connector 44X and the second harness connector 44Y is approximately equal to the length dimension of the first belt-like portion 57. The distance between the device connector 42 and the first harness connector 44X and the distance between the device connector 42 and the second harness connector 44Y are approximately equal. The distance between the first harness connector 44X and the second harness connector 44Y, the distance between the device connector 42 and the first harness connector 44X, and the distance between the device connector 42 and the second harness connector 44Y are the distances in a state where the base member 56 is not bent in the thickness direction. The distance between the first harness connector 44X and the second harness connector 44Y, the distance between the device connector 42 and the first harness connector 44X, and the distance between the device connector 42 and the second harness connector 44Y may be the distances when arranged on the vehicle 10.

[0048] The wire harness 30 does not include wiring for connecting the first harness connector 44X and the second harness connector 44Y. The wire harness 30 does not include wiring for connecting multiple harness connectors 44 to each other. The wire harness 30 only includes equipment wiring 51 for connecting each of the multiple harness connectors 44 to the equipment connector 42.

[0049] The length of each of the first equipment wiring 51X and the second equipment wiring 51Y is within 1 meter. Here, the multiple electric wires 54 have approximately the same length dimension. The length dimension of each electric wire 54 is within 1 meter.

[0050] The multiple electric wires 54 include a highly rigid electric wire 54A and an electric wire 54B that is less rigid than the electric wire 54A. For example, the electric wire 54A is a thick electric wire such as a power line, and the electric wire 54B is a thin electric wire such as a signal line. Here, among the multiple electric wires 54 extending from the first harness connector 44X toward the equipment connector 42, at the bent portion when moving from the first strip portion 57 to the second strip portion 58, the electric wire 54A is located on the innermost peripheral side. The same applies to the multiple electric wires 54 extending from the second harness connector 44Y toward the equipment connector 42. As a result, in the second strip portion 58, the electric wires 54A are arranged at both side edges. For this reason, it becomes easier to grip the highly rigid electric wire 54A during the wiring operation of the second strip portion 58, and the handling of the second strip portion 58 becomes easier. However, among the multiple electric wires 54 extending from the first harness connector 44X toward the equipment connector 42, at the bent portion when moving from the first strip portion 57 to the second strip portion 58, the electric wire 54B may be located on the innermost peripheral side.

[0051] The connector 40 may be held by the base member 56. The electric wire 54 may extend from the end of the base member 56, and the connector 40 may be provided separately from the base member 56.

[0052] <Effect, etc.> According to the wire harness 30 configured as described above, the first partner wire harness 20X and the second partner wire harness 20Y are collectively connected to the device 22 via the device connector 42. As a result, compared to the case where the first partner wire harness 20X and the second partner wire harness 20Y are individually connected to the device 22, the number of connectors 40 of the device 22 can be reduced, and the device 22 to which the wire harness 30 is connected can be miniaturized. Further, since the first device wiring 51X and the second device wiring 51Y are held by the flat base member 56, the intermediate wiring portion becomes flat, and the wire harness 30 can be thinned.

[0053] Also, the distance between the first harness connector 44X and the second harness connector 44Y is shorter than either the distance between the device connector 42 and the first harness connector 44X or the distance between the device connector 42 and the second harness connector 44Y. As a result, the first harness connector 44X and the second harness connector 44Y can be arranged close to each other, facilitating the connection work between the first partner wire harness 20X and the second partner wire harness 20Y and the wire harness 30. Further, the first partner wire harness 20X and the second partner wire harness 20Y can be easily connected to a remote device 22 via the wire harness 30.

[0054] Also, the first device wiring 51X extends from one end of the first strip portion 57 toward the tip of the second strip portion 58, and the second device wiring 51Y extends from the other end of the first strip portion 57 toward the tip of the second strip portion 58. Thereby, the first partner wire harness 20X and the second partner wire harness 20Y extending from opposite sides and the wire harness 30 are easily connected.

[0055] Further, the wire harness 30 does not include wiring for connecting the first harness connector 44X and the second harness connector 44Y. As a result, since the wire harness 30 does not connect the first mating wire harness 20X and the second mating wire harness 20Y, the wire harness 30 is simplified.

[0056] The length of each of the first equipment wiring 51X and the second equipment wiring 51Y is within 1 meter. As a result, the wire harness 30 can connect the equipment 22 and the mating wire harness 20 in a narrow area in the vehicle 10.

[0057] Also, the placement area in the vehicle 10 is the rear area, the first harness connector 44X is a connector for the floor harness 20D, and the second harness connector 44Y is a connector for the rear harness 20E. As a result, in the rear area of the vehicle 10, the floor harness 20D and the rear harness 20E are connected to the equipment 22 via the wire harness 30.

[0058] [Embodiment 2] The wire harness 130 according to Embodiment 2 will be described. FIG. 5 is a perspective view showing how the wire harness 130 according to Embodiment 2 is arranged in the vehicle 10. FIG. 6 is a plan view showing the wire harness 130 according to Embodiment 2. FIG. 7 is an exploded plan view showing the wire harness 130 according to Embodiment 2. FIG. 8 is a cross-sectional view taken along line VIII-VIII of FIG. 6. In the description of the present embodiment, the same reference numerals are given to the same components as those described so far, and the description thereof is omitted.

[0059] The wire harness 130 connects a plurality of mating wire harnesses 20 to the equipment 122. The placement area of the wire harness 130 is different from the placement area of the wire harness 30. The placement area of the wire harness 130 is in front of the vehicle 10 compared to the placement area of the wire harness 30. The placement area of the wire harness 130 is the area where the dash panel 11 and the cowl side panel 15 intersect.

[0060] The dash panel 11 separates the engine room and the passenger compartment in the vehicle 10. The area in front of the dash panel 11 is the engine room, and the area behind the dash panel 11 is the passenger compartment. Usually, an instrument panel is provided behind the dash panel 11, and the instrument panel is exposed in the passenger compartment. The dash panel 11 includes a main body portion 12 and a protruding portion 13. The main surface of the main body portion 12 of the dash panel 11 extends in the left-right direction and the up-down direction in the vehicle 10. The protruding portion 13 is provided below the left-right ends of the main body portion 12. The protruding portion 13 is a portion that protrudes toward the passenger compartment side from the main body portion 12. The protruding portion 13 is a portion for providing a wheelhouse in the vehicle 10.

[0061] The cowl side panels 15 are connected to the dash panel 11 on each of the left and right sides of the dash panel 11. The main surface of the cowl side panel 15 extends in the front-rear direction and the up-down direction in the vehicle 10. In FIG. 1, the area where the cowl side panel 15 provided on the left side of the dash panel 11 intersects with the dash panel 11 is shown. The lower edge of the front side of the cowl side panel 15 is bent according to the protruding portion 13.

[0062] The end of the inner panel reinforcement 17 is fixed to the cowl side panel 15. The inner panel reinforcement 17 is provided between the dash panel 11 and the instrument panel. The inner panel reinforcement 17 is a bar-shaped member that is long in the left-right direction. Below the area where the dash panel 11 and the cowl side panel 15 intersect, a floor panel 18 is provided. The main surface of the floor panel 18 extends in the front-rear direction and the left-right direction in the vehicle 10.

[0063] The combination of a plurality of counterpart wire harnesses 20 connected to the wire harness 130 is different from the combination of a plurality of counterpart wire harnesses 20 connected to the wire harness 30. Some of the counterpart wire harnesses 20 may be connected to both the wire harness 30 and the wire harness 130. There may be no counterpart wire harness 20 connected to both the wire harness 30 and the wire harness 130.

[0064] Examples of the counterpart wire harness 20 connected to the wire harness 130 include an engine room harness 20A, an instrument panel harness 20B, a door harness 20C, and a floor harness 20D. The floor harness 20D is connected to both the wire harness 30 and the wire harness 130. The floor harness 20D is connected to the wire harness 130 in front of the area where it is disposed, and is connected to the wire harness 30 behind the area where it is disposed. As the counterpart wire harness 20 connected to the wire harness 130, a roof harness 20F may be assumed. The roof harness 20F is disposed on the roof.

[0065] The area where the wire harness 130 is disposed and the area where the engine room harness 20A is disposed are partitioned by the dash panel 11. Here, a through hole 14 is formed in the dash panel 11. The wire harness 130 and the engine room harness 20A are connected through the through hole 14. Similarly, the area where the wire harness 130 is disposed and the area where the door harness 20C is disposed are partitioned by the cowl side panel 15. Here, a through hole 16 is formed in the cowl side panel 15. The wire harness 130 and the door harness 20C are connected through the through hole 16. The roof is located above the area where the dash panel 11 and the cowl side panel 15 intersect. For example, the end of the roof harness 20F that is connected to the wire harness 130 extends along the A pillar 19 from the roof to the area where the dash panel 11 and the cowl side panel 15 intersect or the vicinity thereof.

[0066] Device 122 is a device provided separately from device 22. Device 122 is arranged in the same area as the arrangement area of wire harness 130. In the example shown in FIG. 1, device 122 is fixed to cowl side panel 15. Device 122 may be fixed to dash panel 11, in-panel reinforcement 17, floor panel 18, or the like.

[0067] Device 122 is a zone ECU different from device 22. In this case, the devices to be controlled by device 122 as the zone ECU are a plurality of devices at the connection destinations of engine room harness 20A, in-panel harness 20B, door harness 20C, and floor harness 20D. However, device 122 which is an ECU may be a general ECU other than the zone ECU. Also, device 122 does not have to be an ECU, and may be, for example, a junction block (also referred to as an electrical connection box, etc.).

[0068] Wire harness 130 includes device connector 142, a plurality of types of harness connectors 144, and a plurality of wirings 150. Here, as the plurality of types of harness connectors 144, an engine room harness connector 144A, an in-panel harness connector 144B, a door harness connector 144C, and a floor harness connector 144D are provided. The plurality of wirings 150 include a plurality of device wirings 151 and a through-circuit wiring 52. The device wiring 151 connects the device connector 142 and the harness connector 144. The through-circuit wiring 52 connects the harness connectors 144 to each other.

[0069] As shown in FIG. 7, here, as the wiring 151 for equipment, wiring 151A, 151B, 151C, and 151D for equipment are provided. The wiring 151A for equipment connects the connector 144A for the engine room harness and the connector 142 for equipment. The wiring 151B for equipment connects the connector 144B for the instrument panel harness and the connector 142 for equipment. The wiring 151C for equipment connects the connector 144C for the door harness and the connector 142 for equipment. The wiring 151D for equipment connects the connector 144D for the floor harness and the connector 142 for equipment. Note that each of the wirings 151A, 151B, 151C, and 151D for equipment may be one or a plurality of them.

[0070] As shown in FIG. 7, here, as the wiring 52 for the through circuit, wiring 52A, 52B, 52C, 52D, and 52E for the through circuit are provided. The wiring 52A for the through circuit connects the connector 144A for the engine room harness and the connector 144B for the instrument panel harness. The wiring 52B for the through circuit connects the connector 144A for the engine room harness and the connector 144D for the floor harness. The wiring 52C for the through circuit connects the connector 144B for the instrument panel harness and the connector 144C for the door harness. The wiring 52D for the through circuit connects the connector 144B for the instrument panel harness and the connector 144D for the floor harness. The wiring 52E for the through circuit connects the connector 144C for the door harness and the connector 144D for the floor harness. Note that each of the wirings 52A, 52B, 52C, 52D, and 52E for the through circuit may be one or a plurality of them.

[0071] Therefore, here, among the 10 paths between the 5 types of connectors 142 and 144, the wiring 150 is provided for 9 paths other than one path between the connector 144A for the engine room harness and the connector 144C for the door harness.

[0072] The four types of harness connectors 144, namely the engine room harness connector 144A, the instrument panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D, are all connected to the device connector 142 via the device wiring 151. Among the four types of harness connectors 144, namely the engine room harness connector 144A, the instrument panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D, six combinations are generated when two of them are selected. In any of the six combinations, one harness connector 144 can be the first harness connector, and the other harness connector 144 can be the second harness connector. Further, five combinations out of the six combinations, excluding the combination consisting of the engine room harness connector 144A and the door harness connector 144C, have the through-circuit wiring 52 for connecting the two types of harness connectors 144 in the combination. On the other hand, here, the wire harness 130 does not have the through-circuit wiring 52 for connecting the engine room harness connector 144A and the door harness connector 144C.

[0073] Here, the types of connectors in the wire harness 130 are the five types of the device connector 142, the engine room harness connector 144A, the instrument panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D. Therefore, when each of the device connector 142, the engine room harness connector 144A, the instrument panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D includes a plurality of split connectors, the number thereof is preferably three or less. For example, when the four counterpart wire harnesses 20, namely the engine room harness 20A, the instrument panel harness 20B, the door harness 20C, and the floor harness 20D, are respectively connected to the device 122, it is necessary to fit four sets of connectors. On the other hand, when the device connector 142 is composed of three or less split connectors, the number of sets of connectors to be fitted can be three or less.

[0074] The number of the counterpart wire harnesses 20 connected to the wire harness 130 is larger than the number of the counterpart wire harnesses 20 connected to the wire harness 30. Also, the number of the wirings 150 of the wire harness 130 is larger than the number of the wirings 50 of the wire harness 30. As shown in FIG. 7, here, a part of the plurality of wirings 150 is fixed to the base member 62 and grouped together to form a first wiring group 60. Also, another part of the plurality of wirings 150 is fixed to the base member 62 and grouped together to form a second wiring group 70. Of course, the plurality of wirings 150 may be grouped together without being formed into the first wiring group 60 and the second wiring group 70.

[0075] The way of dividing the plurality of wirings 150 into the first wiring group 60 and the second wiring group 70 is not particularly limited and can be set as appropriate. Here, based on the equipment wiring 151 and the through-circuit wiring 52, the plurality of wirings 150 are divided. Specifically, the majority of the first wiring group 60 is the equipment wiring 151. The majority of the second wiring group 70 is the through-circuit wiring 52. 60% or more of the first wiring group 60 may be the equipment wiring 151, 70% or more may be the equipment wiring 151, 80% or more may be the equipment wiring 151, 90% or more may be the equipment wiring 151. Also, all (100%) of the first wiring group 60 may be the equipment wiring 151. Similarly, 60% or more of the second wiring group 70 may be the through-circuit wiring 52, 70% or more may be the through-circuit wiring 52, 80% or more may be the through-circuit wiring 52, 90% or more may be the through-circuit wiring 52. Also, all (100%) of the second wiring group 70 may be the through-circuit wiring 52.

[0076] In the example shown in FIG. 7, all (100%) of the first wiring group 60 is the equipment wiring 151. Also, 90% or more of the second wiring group 70 is the through-circuit wiring 52. Among the equipment wirings 151, an equipment wiring 151A that connects the engine room harness connector 144A and the equipment connector 142 is provided in the second wiring group 70. The equipment wirings 151B, 151C, and 151D excluding the equipment wiring 151A among the equipment wirings 151 are provided in the first wiring group 60. All of the through-circuit wirings 52 are provided in the second wiring group 70.

[0077] The first wiring group 60 and the second wiring group 70 are each formed flat and laminated on each other. Here, the first wiring group 60 has a plurality of electric wires 61 and a flat base member 62 to which the plurality of electric wires 61 are fixed. The second wiring group 70 has a plurality of electric wires 71 and a flat base member 72 to which the plurality of electric wires 71 are fixed.

[0078] In the first wiring group 60, the electric wires 61 are arranged so as not to cross each other on the base member 62. Also in the second wiring group 70, the electric wires 71 are arranged so as not to cross each other on the base member 72. Thereby, an increase in the thickness of the first wiring group 60 and the second wiring group 70 is suppressed, and an increase in the thickness of the wire harness 130 formed by laminating the first wiring group 60 and the second wiring group 70 is suppressed. However, in at least one of the first wiring group 60 and the second wiring group 70, a crossing portion where the electric wires cross each other on the base member may be provided.

[0079] Here, a part of the wire harness 130 is arranged along the dash panel 11. The wiring portion extending from the engine room harness connector 144A is held so as to be arranged along the dash panel 11.

[0080] Another part of the wire harness 130 is arranged along the cowl side panel 15. The in - panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D are arranged in the height direction, and the wiring portions extending from each of the in - panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D are held so as to be arranged along the cowl side panel 15. Also, when the roof harness 20F is assumed as the mating wire harness 20, the roof harness connector 144F is provided as one of the plurality of types of harness connectors 144. The roof harness connector 144F may be arranged, for example, above the equipment connector 142, the engine room harness connector 144A, the in - panel harness connector 144B, the door harness connector 144C, and the floor harness connector 144D in the vehicle. The wiring connected to the roof harness connector 144F may extend vertically along the side of the equipment 122.

[0081] Between the portion of the wire harness 130 arranged along the dash panel 11 and the portion arranged along the cowl side panel 15, the electric wire 71 and the base member 72 are arranged in a state of being bent in the thickness direction. Here, the portion arranged along the dash panel 11 is only the second wiring group 70 out of the first wiring group 60 and the second wiring group 70. For this reason, the wire harness 130 is easily bent in the thickness direction between the portion arranged along the dash panel 11 and the portion arranged along the cowl side panel 15.

[0082] The base members 62 and 72 have path bending portions in the portions arranged along the cowl side panel 15. The path bending portions are formed in a shape bent along the protruding portion 13. By arranging the electric wires 61 and 71 along the path bending portions, it becomes easy to arrange the electric wires 61 and 71 along the protruding portion 13. For example, the wiring 150 extending toward the door harness connector 144C and the wiring 150 extending toward the floor harness connector 144D are arranged along the path bending portions. Branch portions are provided in the middle of the path bending portions in the base members 62 and 72. The wiring 150 extending toward the door harness connector 144C and the wiring 150 extending toward the floor harness connector 144D branch at the branch portions.

[0083] The first wiring group 60 and the second wiring group 70 are laminated so that the main surface of the base member 62 to which the electric wire 61 is fixed faces the main surface of the base member 62 to which the electric wire 71 is fixed. Thereby, the electric wires 61 and 71 are surrounded and protected by the base members 62 and 72. However, the first wiring group 60 and the second wiring group 70 may be laminated so that the main surface of the base member 62 to which the electric wire 61 is fixed faces the main surface of the base member 72 where the electric wire 71 is not fixed, or the main surface of the base member 72 to which the electric wire 71 is fixed faces the main surface of the base member 62 where the electric wire 61 is not fixed. Also, the first wiring group 60 and the second wiring group 70 may be laminated so that the main surface of the base member 62 where the electric wire 61 is not fixed faces the main surface of the base member 72 where the electric wire 71 is not fixed.

[0084] The base member 62 has an extension piece 62a. The extension piece 62a is provided on both sides of the portion where the electric wire 61 is arranged. The base member 72 also has a similar extension piece 72a. By fixing the extension piece 62a of the base member 62 and the extension piece 72a of the base member 72, the first wiring group 60 and the second wiring group 70 are fixed. However, the extension piece 62a of the base member 62 and the extension piece 72a of the base member 72 do not have to be fixed.

[0085] The length of each of the plurality of wirings 150 is within 1 meter. In the wire harness 130, the longest wiring 150 is the through-circuit wiring 52B that connects the engine room harness connector 144A and the floor harness connector 144D, or the through-circuit wiring 52C that connects the in-panel harness connector 144B and the floor harness connector 144D. The lengths of these through-circuit wirings 52B and 52C are within 1 meter.

[0086] Even with the wire harness 130 configured as described above, for effects other than those due to differences in the placement area, the same effects as those of the wire harness 30 can be obtained. According to the wire harness 130, in the area where the dash panel 11 and the cowl side panel 15 intersect, a plurality of mating wire harnesses 20 can be connected to the device 122.

[0087] [Modification Example] Modification examples of the wire harnesses 30 and 130 will be described. Hereinafter, a modification example of the wire harness 130 will be taken as an example for specific description, but unless there is a particular contradiction, it can also be applied to the wire harness 30.

[0088] FIG. 9 is a cross-sectional view showing a wire harness 230 according to a first modification example. FIG. 10 is an exploded plan view showing the wire harness 230 according to the first modification example.

[0089] The wire harness 230 according to the first modification example differs from the above-described wire harness 130 in that it further includes a rigid member 80. The rigid member 80 has higher rigidity than the sheet member. The rigid member 80 is more likely to hold the wiring forms of the first wiring group 60 and the second wiring group 70 than the sheet member. As a result, when the rigid member 80 is arranged in the vehicle 10, the wiring 150 can be arranged along a predetermined path. Such a rigid member 80 may be formed of, for example, metal or hard resin.

[0090] In the wire harness 230, the location where the rigid member 80 is provided is not particularly limited and can be set as appropriate. Here, the rigid member 80 is provided in a portion of the wire harness 230 that is arranged along the cowl side panel 15. The rigid member 80 is not provided in the portion of the wire harness 230 that is arranged along the dash panel 11.

[0091] The rigid member 80 is provided so as to cover the entire portion of the wire harness 230 that is arranged along the cowl side panel 15. The rigid member 80 may be provided so as to cover a part of the portion of the wire harness 230 that is arranged along the cowl side panel 15. For example, the rigid member 80 may be provided so as to cover the portion located upward along the vertical direction (here, the portion extending from the in-panel harness connector 144B and the portion extending from the device connector 142).

[0092] The rigid member 80 may be arranged between the wire harness 230 and the cowl side panel 15. The wire harness 230 may be arranged between the rigid member 80 and the cowl side panel 15.

[0093] The shape of the rigid member 80 is not particularly limited and can be set as appropriate. Here, the rigid member 80 has a trough shape having a bottom 81 and side walls 82. The first wiring group 60 and the second wiring group 70 are accommodated in the accommodation portion surrounded by the bottom 81 and the side walls 82. The rigid member 80 may have a lid that covers the opening of the accommodation portion. The rigid member 80 may have only the bottom 81 without having the side walls 82.

[0094] The wire harness 130 may include a rigid member 80 as a base member instead of a flexible sheet member, without including the flexible sheet member as a base member. In the rigid member 80, a partition wall may be provided between a pair of side walls 82. Thereby, a plurality of accommodating portions are provided in the rigid member. In this case, a part of a plurality of wirings may be accommodated in the first accommodating portion to form a first wiring group, and another part of the plurality of wirings may be accommodated in the second accommodating portion to form a second wiring group. Further, for example, the equipment wiring 151 and the through-circuit wiring 52 may be separately accommodated in a plurality of accommodating portions. Further, for example, the power line 461 and the signal line 471 may be separately accommodated in a plurality of accommodating portions.

[0095] FIG. 11 is a plan view showing a wire harness 330 according to a second modification.

[0096] In the wire harness 330 according to the second modification, the locations where the base members 362 and 372 are provided are different from the locations where the base members 62 and 72 are provided in the wire harness 130. Specifically, at corresponding locations of the first wiring group 360 and the second wiring group 370, a plurality of base members 362 and 372 are provided at intervals along the extending directions of the plurality of electric wires 71 and 61. Thereby, compared with the portion where the plurality of base members 362 and 372 are provided, the plurality of electric wires 71 and 61 are more likely to bend at the portion between the plurality of base members 362 and 372, and it is easier to absorb a path difference or an extra length. Thereby, the common wire harness 330 is more likely to be applied to vehicles of different sizes.

[0097] Here, in the middle part along the extending direction of the wiring 150, the section where the base members 356 and 362 are interrupted is provided in the portion of the wire harness 330 that is arranged along the cowl side panel 15 and extends in the vertical direction. In this case, the wire harness 330 is easily applicable to a plurality of types of vehicles having different height dimensions. In this case, the wire harness 330 is formed according to the vehicle with a large height. When the wire harness 330 is applied to a vehicle with a small height, the electric wires 71 and 61 are bent at the section where 362 and 372 are interrupted, and the extra length is absorbed. For example, the section where 362 and 372 are interrupted may be provided between the door harness connector 144C and the floor harness connector 144D.

[0098] FIG. 12 is an exploded plan view showing a wire harness 430 according to a third modification.

[0099] In the wire harness 430 according to the third modification, the method of dividing the first wiring group 460 and the second wiring group 470 is different from the method of dividing the first wiring group 60 and the second wiring group 70 in the wire harness 130. Here, based on whether the wiring 150 is a power line 461 or a signal line 471, it is sorted into the first wiring group 460 and the second wiring group 470. Specifically, the majority of the second wiring group 470 are signal lines 471. Also, the ratio of the power line 461 in the first wiring group 460 is higher than the ratio of the power line in the second wiring group 470. Thereby, many of the power line 461 and many of the signal line 471 can be separated.

[0100] The ratio of the power line 461 in the first wiring group 460 is not particularly limited and can be set as appropriate. For example, the ratio of the power line 461 in the first wiring group 460 may be 50% or more, or may be less than 50%. That is, the majority of the first wiring group 460 may be the power line 461 or the signal line.

[0101] Also, more than half of all the power lines in the wire harness 430 may be arranged in the first wiring group 460. More than half of all the signal lines in the wire harness 430 may be arranged in the second wiring group 470. The first wiring group 460 may or may not include signal lines. The second wiring group 470 may or may not include power lines.

[0102] In the example shown in FIG. 12, among the wiring 150 connected to the door harness connector 144C and the wiring 150 connected to the floor harness connector 144D, the power line 461 is provided in the first wiring group 460, and the signal line 471 is provided in the second wiring group 470. The power line 461A in the first wiring group 460 connects the door harness connector 144C and the floor harness connector 144D to the device connector 142 respectively. The power line 461B in the first wiring group 460 connects the door harness connector 144C and the floor harness connector 144D to the other harness connector 144 respectively. The signal line 471A in the second wiring group 470 connects the door harness connector 144C and the floor harness connector 144D to the device connector 142 respectively. The signal line 471B in the second wiring group 470 connects the door harness connector 144C and the floor harness connector 144D to the other harness connector 144 respectively.

[0103] FIG. 13 is a perspective view showing a wire harness 530 according to a fourth modification. FIG. 14 is an exploded perspective view showing the wire harness 530 according to the fourth modification.

[0104] In the wire harness 530 according to the fourth modification example, the shape of the connector 46 is different from the shape of the connector 40 in the wire harness 130. Specifically, at least one type of the plurality of types of connectors 46 is composed of a plurality of divided connectors 47 and 48. The plurality of divided connectors 47 and 48 includes a first divided connector 47 and a second divided connector 48. The wiring 150 of the first wiring group 60 is connected to the first divided connector 47. The wiring of the second wiring group 70 is connected to the second divided connector 48. As a result, compared with the case of the wire harness 130, it is less likely that either one of the wiring 150 of the first wiring group 60 and the wiring 150 of the second wiring group 70 is inserted into the connector 40 into which the other one of the wiring 150 of the first wiring group 60 and the wiring 150 of the second wiring group 70 has been inserted in advance. Thereby, it becomes easy to separately manufacture the first wiring group 60 and the second wiring group 70 and then combine them later to form the wire harness 530.

[0105] Here, the first divided connector 47 and the second divided connector 48 are combined to form a stacked connector 46. Therefore, here, at least one type of the plurality of types of connectors 46 is a stacked connector 46 composed of a plurality of divided connectors 47 and 48 combined with each other. The various connectors 40 may be divided in a manner other than the stacked connector 46. For example, the connector 142 for equipment may be divided into a plurality of divided connectors arranged in a direction intersecting the thickness direction. The two divided connectors may be connected to the equipment 122 without being combined.

[0106] FIG. 15 is a cross-sectional view showing a wire harness 630 according to the fifth modification example.

[0107] In the wire harness 630 according to the fifth modification example, the stacking mode of the first wiring group 60 and the second wiring group 70 is different from the stacking mode in the wire harness 130. In the portion where the first wiring group 60 and the second wiring group 70 are stacked, the wirings 150 of the first wiring group 60 and the wirings 150 of the second wiring group 70 are arranged shifted in the parallel direction so as not to stack on each other. Thereby, compared with the case where the wirings 150 of the first wiring group 60 and the wirings 150 of the second wiring group 70 are stacked on each other, the thickness of the wire harness 630 in which the first wiring group 60 and the second wiring group 70 are stacked becomes smaller. In addition, since the wiring 150 is suppressed from becoming multilayered, the wire harness 630 is likely to bend in the thickness direction. The stacking mode may be provided in a part of the wire harness 630 or may be provided in the whole. For example, the stacking mode may be provided in a portion extending from the door harness connector 144C of the wire harness 630.

[0108] In addition, at least a part of the plurality of types of connectors 40 may be standby connectors. For example, at least a part of the plurality of harness connectors 44 may be standby connectors. Thereby, it becomes easy to connect the counterpart wire harness to the harness connector 44.
