Description

TECHNICAL FIELD The present disclosure relates to wire harnesses and methods of manufacturing wire harnesses.

Conventionally, there is a wire harness that includes a housing that holds a connector and an electric wire that is electrically connected to the connector at one end. Such wire harnesses are sometimes arranged in places where water droplets adhere to the surfaces of electric wires in vehicles such as automobiles. Therefore, the wire harness may include a draining portion for suppressing water droplets from reaching the connector along the electric wire, as described in Patent Document 1, for example.

A wire harness described in Patent Document 1 includes a housing that holds a connector, and a wire having one end electrically connected to a wire-side connector. The electric wire is electrically connected to the connector via the electric wire-side connector by electrically connecting the electric wire-side connector to the connector. The housing has a hook portion on which an electric wire is hooked. The hook portion has a shape in which a part of the ring is interrupted. An electric wire extending from a wire-side connector electrically connected to the connector is once hooked on a hook portion located below the connector, then folded back upward below the hook portion, and then folded again. hooked on the hook. Thus, the wire loop formed below the hook functions as a drainer. Water droplets adhering to the surface of the electric wire travel along the surface of the electric wire and reach the draining portion, and then drop from the lowest point in the draining portion. Therefore, water droplets adhering to the wire are prevented from reaching the connector, and corrosion of the electrical connection portion between the connector and the wire-side connector is suppressed.

By the way, it is difficult for the wire harness described in Patent Literature 1 to be provided with a draining portion unless it is provided with a housing having a hook portion. Therefore, if the housing of a wire harness mounted on a vehicle of a vehicle type that has already been mass-produced does not have a hook portion, it is difficult for the wire harness to have the draining portion described in Patent Document 1. . In order for a wire harness mounted on a vehicle of a vehicle type that has already been mass-produced to have a draining portion described in Patent Document 1, for example, the housing included in the wire harness is changed to a housing having a hook portion. It will be. However, if the housing is changed, there is a concern that the manufacturing apparatus for manufacturing the housing will be changed or the shape of the vehicle body will be changed. Therefore, it is not easy to provide the draining portion described in Patent Document 1 in a wire harness mounted on a vehicle of a vehicle type that has already been mass-produced. Therefore, it is desired to easily provide a draining portion to wire harnesses mounted on vehicles of vehicle models that have already been mass-produced.

[Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure are listed and described.
The wire harness of the present disclosure includes:
[1] at least one electric wire having one end electrically connected to a connector; a housing that holds the connector and is fixed to a first fixing target; a regulating member arranged along the direction in which the electric wire extends and fixed to the electric wire so as not to move relative to the electric wire; a fixing member fixed to a certain second fixing target, wherein the electric wire traces the electric wire from one end of the electric wire to which the connector is electrically connected to the other end of the electric wire. At least 1 The electric wire of the book has a folding point at which the electric wire is folded at a portion between the fixed start point of the electric wire and the connector electrically connected to the electric wire, and the electric wire extends in the extending direction of the electric wire. An end of the regulating member in a direction toward the connector along the direction in which the electric wire extends is defined as a first end, an end of the regulating member opposite to the first end is defined as a second end, and the second end is defined as the second end. Assuming that the direction from the to the first end is defined as a reference direction, in the fixed state, the position of the folding point in the reference direction is located further than the connector electrically connected to the electric wire having the folding point. It is a wire harness on the front side in the reference direction.

According to this configuration, when the wire harness is arranged such that the folding point is located vertically below the connector to which the wire having the folding point is electrically connected, the wire harness adheres to the surface of the wire. Water droplets move downward along the surface of the wire. Then, the water droplet separates from the electric wire near the turning point of the electric wire and falls. In this way, the portion of the wire between the fixation start point and the connector functions as a draining portion that prevents water droplets adhering to the wire from reaching the connector.

The positional relationship between the first fixed target and the second fixed target is constant. Therefore, in the fixed state, the housing and the fixed member have a constant positional relationship. Moreover, since the restricting member is fixed to the electric wire so as not to move relative to the electric wire, the positional relationship with the electric wire is constant. Furthermore, since the fixing member cannot move relative to the electric wire and the regulating member, the positional relationship between the electric wire and the regulating member is constant. For these reasons, in the fixed state, the connector held by the housing and the fixing start point have a fixed positional relationship. As a result, the length of the wire between the fixed starting point and the connector electrically connected to the wire does not change. When the electric wire has a turn-around point in the fixed state, the turn-around point is positioned between the connector electrically connected to the electric wire having the turn-around point and the fixing start point. Therefore, if the housing is fixed to the first fixing object and the fixing member is fixed to the second fixing object, the part between the fixation start point of the electric wire and the connector electrically connected to the electric wire can be fixed. A turn-around point is formed that is located forward of the connector in the reference direction.

Also, the regulating member is fixed to the electric wire. Therefore, in a wire harness mounted on a product that has already been mass-produced, the restricting member can be fixed to the electric wire without changing the shape of the housing. After the regulating member is fixed to the electric wire of the wire harness mounted on the already mass-produced product, the wire harness is fixed, so that the wire harness can be easily provided with the draining portion. Therefore, it is possible to easily provide a draining portion even for products that have already been mass-produced.

[2] It is preferable that the fixing member has a tightening portion that surrounds and tightens the electric wire and the regulating member collectively.
According to this configuration, the fixing member can be easily attached to the wire and the restricting member by the tightening portion so as not to move relative to each other.

[3] When a plurality of the electric wires are provided, the fixing start point closest to the first end is a first fixation start point, and the electric wire having the first fixation start point is a first electric wire, the plurality of the electric wires The electric wire includes a second electric wire different from the first electric wire, and in the fixed state, the first electric wire has the folding point, and the second electric wire is fixed to the regulating member of the electric wire. When the fixing start point of the second electric wire is defined as a second fixing start point, the second fixing start point includes the second end and the first fixing start point in the reference direction. It is preferable that the connector is positioned between the fixing start point and the proximal end of the branch line, and the connector is electrically connected to the distal end of the branch line.

According to this configuration, the branch line is branched from the portion of the electric wire fixed to the regulating member. Therefore, in the fixed state, the position of the base end of the branch line is easily determined.
[4] In the fixed state, the second electric wire has the folding point, and in the fixed state, the position of the folding point of the second electric wire in the reference direction is the tip of the branch line. It is preferably on the front side in the reference direction from the connector electrically connected to the .

According to this configuration, if the housing is fixed to the first fixing target and the fixing member is fixed to the second fixing target, the connector electrically connected to the branch line can be attached to the branch line forward in the reference direction. A folding point located on the side is formed. Therefore, in the fixed state, the branch wire can function as a draining portion that prevents water droplets adhering to the second wire from reaching the connector.

[5] It is preferable to have a first tape member for fixing the branch line in a branched state from a portion of the electric wire extending along the regulating member, and a second tape member for fixing the regulating member to the electric wire. .

According to this configuration, the second tape member is a tape member different from the first tape member that fixes the branch line in a branched state. Therefore, compared to the case where the tape member for fixing the branch line in a branched state and the tape member for fixing the regulating member to the electric wire are the same tape member, the wire harness can be easily manufactured.

[6] The electric wire having the fixing start point closest to the first end has the folding point in the fixed state, and the position of the folding point in the reference direction is the same as that of the housing. It is preferably on the front side in the reference direction.

According to this configuration, the wire harness is arranged so that the turn-back point of the electric wire having the fixing start point closest to the first end is positioned vertically below the connector to which the electric wire is electrically connected. is arranged, it is possible to suppress the adhesion of water droplets that have separated from the wire near the turning point of the wire and dropped to the housing. Therefore, it is possible to further prevent water droplets from reaching the connector.

[7] It is preferable that the regulating member has a rod shape extending linearly.
According to this configuration, the regulating member has a simple shape of a linearly extending bar. Therefore, the restricting member can be manufactured easily. In addition, it is easy to fix the regulating member to the electric wire.

The manufacturing method of the wire harness of the present disclosure includes:
[8] A method of manufacturing a wire harness comprising: a plurality of electric wires having one end electrically connected to a connector; and a housing that holds the connector and is fixed to a first fixing target, an aligning step of aligning the plurality of electric wires so as to form a branch line branching from the main line; a first fixing step of winding a first tape member around the region to fix the branch line in a state in which the branch line is branched from the main line; After arranging the branch line in the area including the branched portion of the main line, the second tape member is wrapped around the main line and the regulating member to make the regulating member immovable relative to the main line. a second fixing step of fixing; and after the second fixing step, moving a fixing member fixed to a second fixing target having a fixed positional relationship with the first fixing target relative to the electric wire and the regulating member. The method of manufacturing a wire harness includes a mounting step of mounting the connector in an impossibly mounted state, and a connector holding step of holding the connector in the housing.

According to this configuration, in the first fixing step, the second fixing step is performed after the first tape member is used to fix the branch line in a branched state from the main line. Therefore, when performing the second fixing step, the branch line is maintained in a state of being branched from the main line. Therefore, it is easy to perform the work of winding the second tape member around the main line and the regulating member and fixing the regulating member to the main line. As described above, the wire harness manufactured by this manufacturing method can be easily provided with a draining portion even for products that have already been mass-produced.

[Details of the embodiment of the present disclosure]
A specific example of the wire harness and the wire harness manufacturing method of the present disclosure will be described below with reference to the drawings. The present invention is not limited to these examples, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims. Also, in the accompanying drawings, the dimensional ratios of components may differ from those in reality or in other figures.

An embodiment of a wire harness and a method for manufacturing the wire harness will be described below.
(Configuration of wire harness 10)
As shown in FIG. 1, the wire harness 10 includes at least one electric wire 11, a restricting member 12, a fixing member 13, and a housing . The wire harness 10 is for electrically connecting electrical devices mounted on a vehicle, for example, an automobile. The posture of the wire harness 10 shown in FIGS. 1 to 3 is the posture when the wire harness 10 is attached to the vehicle body of an automobile.

The wire harness 10 may include multiple electric wires 11 . The wire harness 10 includes, for example, four electric wires 11 . Each electric wire 11 is, for example, a covered electric wire having a core wire made of a conductor and an insulating coating covering the outer periphery of the core wire. Three of the four electric wires 11 are the first electric wires 11a to 11c. The remaining one electric wire 11 is a second electric wire 11d which is a different electric wire 11 from the first electric wires 11a to 11c.

A connector 15 is electrically connected to one end of each electric wire 11 . First connectors 15a to 15c are electrically connected to one ends of the first electric wires 11a to 11c, respectively. A second connector 15d is electrically connected to one end of the second electric wire 11d.

The first electric wires 11a to 11c and the second electric wires 11d constitute, for example, a wire bundle 23 having a trunk line 21 and branch lines 22. As shown in FIG. The first electric wires 11a to 11c and the second electric wires 11d are collectively bundled over a predetermined range in the extending direction of the first electric wires 11a to 11c and the second electric wires 11d. The second electric wire 11d has a branch line 22 branched from the first electric wires 11a to 11c extending as the main line 21. As shown in FIG. A second connector 15 d is electrically connected to the tip of the branch line 22 .

As shown in FIGS. 1 and 2, the regulating member 12 is arranged along the direction in which the wire 11 extends. The regulating member 12 has greater rigidity than the electric wire 11 . The regulating member 12 has a rigidity capable of suppressing bending of the portion of the electric wire 11 fixed to the regulating member 12 . For example, the regulating member 12 has greater rigidity than the trunk line 21 . As a material of the regulation member 12, for example, a synthetic resin such as polypropylene can be used. Note that the material of the regulating member 12 may be a material other than the synthetic resin as long as the rigidity of the regulating member 12 is greater than the rigidity of the electric wire 11 .

The restricting member 12 has, for example, a rod shape extending linearly. The restricting member 12 is arranged with respect to the electric wire 11 so that the extending direction of the restricting member 12 , that is, the longitudinal direction of the restricting member 12 is along the extending direction of the electric wire 11 . Also, the restricting member 12 is arranged in contact with at least one electric wire 11 . For example, the regulating member 12 is arranged along the main line 21 . Further, the regulating member 12 is arranged, for example, so as to be adjacent to a portion of the main line 21 including the location where the branch line 22 branches. That is, the branch line 22 may branch from a portion of the electric wire 11 extending along the restricting member 12 .

The wire harness 10 may have the first tape member 31 . The first tape member 31 fixes the branch line 22 in a branched state from the portion of the electric wire 11 extending along the restricting member 12 . For example, the first tape member 31 is wound around a portion of the trunk line 21 where the branch line 22 branches and a base end region of the branch line 22 . The first tape member 31 is, for example, an adhesive tape. Note that the first tape member 31 may be a non-adhesive tape as long as it can fix the branch line 22 in a branched state from the trunk line 21 .

The wire harness 10 may have a second tape member 32 . The second tape member 32 fixes the regulating member 12 to the wire 11 so as not to move relative to it. In this way, the restricting member 12 may be fixed to the wire 11 by, for example, the second tape member 32 so as not to move relative to it. The second tape member 32 is, for example, an adhesive tape. The second tape member 32 is, for example, spirally wound around the outer periphery of the main line 21 and the regulation member 12 .

Here, among both ends of the regulating member 12 in the direction in which the electric wire 11 extends, the end in the direction toward the connector 15 along the direction in which the electric wire 11 extends is referred to as a first end 12a. Furthermore, let the end opposite to the 1st end 12a be the 2nd end 12b among the both ends of the control member 12 in the direction where the electric wire 11 is extended. That is, the second end 12b is the end in the direction away from the connector 15 along the direction in which the electric wire 11 extends, among both ends of the regulating member 12 in the direction in which the electric wire 11 extends.

A direction from the second end 12b to the first end 12a is defined as a reference direction X1. For example, the reference direction X1 is the direction from the second end 12b to the first end 12a along the direction in which the portion of the main line 21 to which the restricting member 12 is fixed extends.

The second tape member 32 may fix the regulation member 12 to the main line 21 from the second end 12b to the first end 12a, for example. In addition, the second tape member 32 is wound around the electric wire 11 and the regulation member 12 while avoiding the branch line 22 . In a region from the second end 12b to the base end of the branch line 22 along the reference direction X1, the regulating member 12 is fixed to the first electric wires 11a to 11c and the second electric wire 11d. In the area from the base end of the branch line 22 to the first end 12a along the reference direction X1, the regulating member 12 is fixed to the first electric wires 11a to 11c. The base end of the branch line 22 is positioned, for example, within the range between the first end 12a and the second end 12b in the reference direction X1. The branch line 22 branches from a portion of the electric wire 11 fixed to the regulating member 12 .

The first electric wire 11a is fixed to the regulating member 12 when the first electric wire 11a is traced from one end of the first electric wire 11a to which the first connector 15a is electrically connected to the other end. has a first fixed starting point P1 from which The first fixation start point P1 is a point where fixation of the first electric wire 11a by the second tape member 32 starts at the first electric wire 11a when the first electric wire 11a is traced from the first connector 15a toward the regulating member 12. be. The first fixing start point P1 is located, for example, in the vicinity of a portion of the first electric wire 11a that is aligned with the first end 12a in a direction orthogonal to the reference direction X1.

Similarly, the first electric wire 11b reaches the regulating member 12 when following the first electric wire 11b from one end of the first electric wire 11b to which the first connector 15b is electrically connected to the other end of the first electric wire 11b. has a first fixation start point P2 from which fixation of . Also, the first electric wire 11c is connected to the regulating member 12 when the first electric wire 11c is traced from one end of the first electric wire 11c to which the first connector 15c is electrically connected to the other end. It has a first fixation start point P3 where fixation begins. The first fixing start point P2 is located, for example, in the vicinity of a portion of the first electric wire 11b that is aligned with the first end 12a in a direction orthogonal to the reference direction X1. The first fixation start point P3 is, for example, a point in the first electric wire 11c that is aligned with the first end 12a in a direction perpendicular to the reference direction X1. Note that the first fixed start points P1 to P3 have the same position in the reference direction X1.

The second electric wire 11d is fixed to the regulating member 12 when the second electric wire 11d is traced from one end of the second electric wire 11d to which the second connector 15d is electrically connected to the other end. has a second fixed starting point P4 from which The second fixation start point P4 is a point where fixation of the second electric wire 11d by the second tape member 32 starts at the second electric wire 11d when the second electric wire 11d is traced from the second connector 15d toward the regulating member 12. be. The second fixed start point P4 is positioned, for example, between the second end 12b and the first fixed start points P1 to P30 in the reference direction X1. Also, the second fixed starting point P4 is located at the proximal end of the branch line 22, for example.

The second fixed start point P4 is located on the rear side in the reference direction X1 relative to each of the first fixed start points P1 to P3. Among the four fixed starting points P1 to P4, the first fixed starting points P1 to P3 are located closest to the first end 12a. That is, among the four fixed start points P1 to P4, the first fixed start points P1 to P3 are closest to the first end 12a in the reference direction X1. Further, among the four fixed start points P1 to P4, the first fixed start points P1 to P3 are positioned furthest forward in the reference direction X1.

As shown in FIGS. 2 and 3, the vehicle body has a first fixed target 61 and a second fixed target 62 for attaching the wire harness 10 to the vehicle body. The second fixed target 62 is located away from the first fixed target 61 . The first fixed target 61 and the second fixed target 62 have a fixed positional relationship. The first fixed object 61 is, for example, a part of a vehicle body panel. Also, the second fixed object 62 is, for example, a part of the vehicle body panel.

The fixing member 13 is attached to the wire 11 and the restricting member 12 so as not to move relative to each other. Furthermore, the fixed member 13 is fixed to the second fixed object 62 . The fixing member 13 has, for example, a base portion 41 , a tightening portion 42 and a fixing portion 43 .

The tightening portion 42 has a belt shape, for example. One end of the tightening portion 42 is fixed to the base portion 41 . For example, the tightening portion 42 is wound around the electric wire 11 and the restricting member 12 so as to collectively surround the electric wire 11 and the restricting member 12 near the second end 12b. The tightening portion 42 surrounds the electric wire 11 and the regulating member 12, and the other end region of the tightening portion 42 is fixed to the base portion 41 by uneven engagement between the hole and the protrusion. The tightening portion 42 tightens the wire 11 and the restricting member 12, for example. In this manner, the fixing member 13 may be attached to the wire 11 and the restricting member 12 by the tightening portion 42 .

The fixing portion 43 may be provided integrally with the base portion 41 . The fixed part 43 has, for example, a mounting post 44 , an engaging claw 45 and an elastic piece 46 . The mounting post 44 protrudes from the base 41, for example, along a direction orthogonal to the reference direction X1. The fixed portion 43 has, for example, two engaging claws 45 . It should be noted that only one of the two engaging claws 45 is shown in FIG. The other engaging claw 45 is positioned on the back side of the mounting post 44 in the plane of the drawing. Each engaging claw 45 extends from the distal end of the mounting support 44 toward the proximal end of the mounting support 44 . Each engaging claw 45 extends away from the mounting post 44 from the proximal end of each engaging claw 45 toward the distal end. Each engaging claw 45 is elastically deformable in a direction in which the tip of each engaging claw 45 approaches the mounting post 44 .

The elastic piece 46 extends from the base end region of the mounting post 44 toward the outer circumference of the mounting post 44 . The elastic piece 46 has, for example, a flange shape surrounding the base end of the mounting support 44 . The tip of the elastic piece 46 is positioned closer to the tip of the mounting post 44 than the base end of the elastic piece 46 in the projecting direction of the mounting post 44 from the base portion 41 . In the brim-shaped elastic piece 46 , the proximal end of the elastic piece 46 is the inner peripheral edge of the elastic piece 46 , and the tip of the elastic piece 46 is the outer peripheral edge of the elastic piece 46 . The elastic piece 46 is elastically deformable so that the tip of the elastic piece 46 moves along the direction from the tip to the base end of the mounting post 44 with respect to the base end of the elastic piece 46 .

The fixing member 13 is fixed to the second fixing target 62 by fixing the fixing portion 43 to the second fixing target 62 . The second fixed target 62 has, for example, a through hole (not shown). The fixing portion 43 is fixed to the second fixing target 62 by inserting the mounting post 44 and the engaging claw 45 into the through hole. For example, when the mounting post 44 and the engaging claw 45 are inserted into the through hole, the elastic piece 46 and the engaging claw 45 sandwich the portion of the second fixed object 62 around the through hole. . Therefore, the fixing member 13 is positioned with respect to the second fixing target 62 in the projecting direction of the mounting support 44 from the base 41 .

As shown in FIG. 3 , the housing 14 is fixed to the first fixed target 61 . The housing 14 has, for example, a fixing portion 51 fixed to the first fixing target 61 . The housing 14 has, for example, two fixing portions 51 . Since each fixing portion 51 has the same configuration as that of the fixing portion 43, description of each fixing portion 51 is omitted.

The housing 14 is fixed to the first fixed target 61 by fixing each fixing portion 51 to the first fixed target 61 . The first fixed object 61 has, for example, two through holes (not shown). The two through holes are, for example, separated in the vertical direction of the vehicle. Each fixing part 51 is fixed to the first fixing target 61 by inserting the mounting strut 44 and the engaging claw 45 of each fixing part 51 into the two through holes.

As shown in FIGS. 1 and 3, the housing 14 may have receiving holes 52a and 52b. Here, in the wire harness 10, the state in which the housing 14 is fixed to the first fixed target 61 and the fixing member 13 is fixed to the second fixed target 62 is hereinafter referred to as a "fixed state". In the fixed state, the accommodation holes 52a and 52b are separated from each other in the reference direction X1. A second connector 15d is inserted into the receiving hole 52a. The first connector 15a is inserted into the receiving hole 52b. The housing 14 holds the second connector 15d inside the housing hole 52a and holds the first connector 15a inside the housing hole 52b.

The housing 14 may have connector holding portions 53a and 53b. The connector holding portions 53a and 53b are positioned on the outer peripheral surface of the housing 14, for example. In the fixed state, the connector holding portion 53a and the connector holding portion 53b are separated from each other in the reference direction X1. The connector holding portion 53a holds the first connector 15b. The connector holding portion 53b holds the first connector 15c. For example, each of the connector holding portions 53a and 53b has an elastically deformable engaging claw (not shown). The first connector 15b is fixed to the engaging claws of the connector holding portion 53a by snap-fitting, for example.

By the way. That is, the first folding point P11 is a portion of the first electric wire 11a between the first fixing start point P1 and the first connector 15a where the first electric wire 11a is folded back in the direction opposite to the reference direction X1. The position of the first turn-back point P11 in the reference direction X1 is forward of the first connector 15a in the reference direction X1. A portion of the first electric wire 11a between the first fixation starting point P1 and the first connector 15a, which has a J shape, for example, is a draining portion 16a.

Similarly, each of the first electric wires 11b and 11c is folded back at a portion between the first fixing start points P2 and P3 of each of the first electric wires 11b and 11c and the first connectors 15b and 15c. It has first folding points P12 and P13. The position of the first turn-back point P12 in the reference direction X1 is forward of the first connector 15b in the reference direction X1.

In the fixed state, the positions of the first folding points P11 to P13 in the reference direction X1 are, for example, forward of the housing 14 in the reference direction X1. That is, the positions of the first turnaround points P11 to P13 in the reference direction X1 may be on the front side in the reference direction X1 from the front end of the housing 14 in the reference direction X1.

Further, in the fixed state, the portion of the second electric wire 11d between the second fixing start point P4 and the second connector 15d is, for example, a U-shape or a J-shape that bulges forward in the reference direction X1, or It becomes a V-shaped folded back shape. Then, in the fixed state, the second electric wire 11d is, for example, at a second folding point P14 at which the second electric wire 11d is folded back to a portion between the second fixing start point P4 of the second electric wire 11d and the second connector 15d. have The length of the portion of the second electric wire 11d between the second fixing start point P4 and the second connector 15d is set, for example, to a length at which the second folding point P14 is formed in the fixed state. .

(Manufacturing method of wire harness 10)
A method of manufacturing the wire harness 10 will be described.
(Alignment process)
As shown in FIG. 4, for example, first, an aligning step is performed to align the plurality of electric wires 11 so that a trunk line 21 and branch lines 22 branching from the trunk line 21 are formed. A connector 15 is electrically connected to one end of each electric wire 11 aligned in the alignment process. In the aligning step, for example, the three first electric wires 11a to 11c and one second electric wire 11d are aligned so that the branch wire 22 is branched. The first electric wires 11a to 11c and the second electric wires 11d are aligned on a jig (not shown) so that the portion forming the main line 21 extends linearly. The second electric wires 11 d are arranged on a jig (not shown) so that the branch wires 22 are branched from the main wire 21 . In FIG. 4, since the electric wire 11 is illustrated in a fixed state, the first electric wires 11a to 11c are illustrated in a folded state. However, in the aligning process, the first electric wires 11a to 11c are arranged linearly without being folded back, for example.

When the aligning process is completed, the plurality of electric wires 11 are aligned with the main line 21 extending straight and the branch lines 22 branching off from the main line 21 . For example, the plurality of electric wires 11 are maintained in an aligned state by a jig. The first electric wires 11a to 11c are linearly aligned in a range from one end to which the first connectors 15a to 15c are electrically connected to a predetermined position on the other end side.

(First fixing step)
After the aligning step, a first fixing step of fixing the branch line 22 in a branched state from the main line 21 is performed. For example, the alignment process is followed by the first fixing process. In the first fixing step, the first tape member 31 is wound around the portion where the branch line 22 of the main line 21 diverges and the base end region of the branch line 22 in the plurality of electric wires 11 aligned in the alignment step. The first tape member 31 fixes the branch line 22 in a branched state from the trunk line 21 . The first tape member 31 may be wound in any manner as long as it can fix the branch line 22 in a branched state from the trunk line 21 .

When the first fixing step is completed, the first tape member 31 is wound around the portion of the trunk line 21 where the branch line 22 branches and the base end region of the branch line 22 . The first tape member 31 fixes the branch line 22 in a branched state from the trunk line 21 .

(Second fixing step)
As shown in FIG. 5, after the first fixing step, the second fixing step of fixing the restricting member 12 to the main line 21 so as not to move relative to each other is performed. For example, the first fixing step is followed by the second fixing step. When starting the second fixing process, the electric wire 11 after the completion of the first fixing process is placed on the workbench. A second fixing step is performed on a workbench. In FIG. 5, since the electric wire 11 is illustrated in a fixed state, the first electric wires 11a to 11c are illustrated in a folded state. However, when the second fixing step is performed, the first electric wires 11a to 11c are, for example, arranged straight without being folded back.

In the second fixing step, first, the regulating member 12 is arranged in a region of the main line 21 including the branched portion of the branch line 22 . At this time, the regulating member 12 is positioned in the extending direction of the trunk line 21 with respect to the trunk line 21 using, for example, a positioning jig (not shown). The positioning jig defines, for example, the distance between the first end 12a of the regulating member 12 and the first connectors 15a-15c electrically connected to the first electric wires 11a-11c. The regulating member 12 is arranged, for example, so that the longitudinal direction of the regulating member 12 substantially coincides with the direction in which the main line 21 extends. Further, the regulating member 12 is placed in contact with the main line 21 at the positioned location.

After that, the second tape member 32 is wrapped around the trunk line 21 and the restricting member 12 to fix the restricting member 12 to the trunk line 21 so as not to move relative to the trunk line 21 . The second tape member 32 is, for example, spirally wound around the outer peripheries of the main line 21 and the regulation member 12 . Also, the second tape member 32 is wound, for example, in a range including a range between the first end 12a and the second end 12b in the direction in which the trunk line 21 extends. Also, the second tape member 32 is wound around the electric wire 11 and the regulation member 12 while avoiding the branch line 22 .

When the second fixing step is completed, the restricting member 12 is fixed to the main line 21 by the second tape member 32 so as not to move relative to it.
(Mounting process)
After the second fixing step, a mounting step of mounting the fixing member 13 fixed to the second fixing target 62 to the electric wire 11 and the restricting member 12 so as not to move relative to each other is performed. In addition, in FIG. 5, the fixing member 13 is illustrated with a two-dot chain line. For example, the mounting process is performed after the second fixing process.

In the mounting step, the tightening portion 42 is mounted on the electric wire 11 and the restricting member 12 . For example, the tightening portion 42 is wound around the outer circumferences of the electric wire 11 and the restricting member 12 by one turn. Then, the tightening portion 42 is fixed to the base portion 41 while tightening the wire 11 and the restricting member 12 by the tightening portion 42 . When the mounting process is finished, the fixing member 13 is mounted on the wire 11 and the restricting member 12 so as not to move relative to each other.

(connector holding process)
Next, a connector holding step for holding the connector 15 in the housing 14 is performed. For example, the connector holding process is performed after the mounting process. The housing 14 is manufactured and prepared in advance before the connector holding process is started. In the connector holding step, the connector 15 connected to each electric wire 11 is held by the housing 14 .

As shown in FIG. 3, for example, the second connector 15d is inserted into the accommodation hole 52a. Also, the first connector 15a is inserted into the accommodation hole 52b. Also, the first connectors 15b and 15c are fixed to the connector holding portions 53a and 53b, respectively. The order in which the housing 14 holds the first connectors 15a to 15c and the second connector 15d does not matter.

When the connector holding step is accommodated, the connector 15 electrically connected to each of the wires 11 is held by the housing 14 .
The wire harness 10 is completed when the aligning process, the first fixing process, the second fixing process, the mounting process, and the connector holding process are completed. The positional relationship between the housing 14 and the regulating member 12 is not fixed until the completed wire harness 10 is fixed.

(Action of Embodiment)
The operation of this embodiment will be described.
As shown in FIGS. 1 to 3, when attaching the wire harness 10 to the vehicle body, an operator fixes each of the fixing portions 51 to the first fixing target 61, whereby the housing 14 is attached to the first fixing target 61. fixed. Further, the worker fixes the fixing member 13 to the second fixing target 62 by fixing the fixing portion 43 to the second fixing target 62 . As a result, the wire harness 10 is fixed.

Since the positional relationship between the first fixed object 61 and the second fixed object 62 in the vehicle body is constant, the positional relationship between the housing 14 and the fixed member 13 is constant when the wire harness 10 is in the fixed state. Moreover, the fixing member 13 is attached to the electric wire 11 and the restricting member 12 so as not to move relative to each other. Therefore, the positional relationship between the fixing member 13 and the wire 11 and between the fixing member 13 and the restricting member 12 is constant. Furthermore, since the regulating member 12 has greater rigidity than the electric wire 11, it is difficult to deform in the fixed state. Therefore, the positional relationship between the fixing member 13 and each of the first fixing start points P1 to P3 and the second fixing start point P4 is constant. For these reasons, when the wire harness 10 is in the fixed state, the first turn-back point P11 is formed between the first fixing start point P1 and the first connector 15a in the first electric wire 11a. Similarly, first folding points P12 and P13 are formed at portions between the first fixing start points P2 and P3 and the first connectors 15b and 15c on the first electric wires 11b and 11c. Also, a second folding point P14 is formed at a portion between the second fixing start point P4 and the second connector 15d in the second electric wire 11d.

In the fixed state, the reference direction X1 generally coincides with, for example, the downward direction of the vehicle. Then, in the fixed state, the first folding point P11 is located below the first connector 15a in the vertical direction of the vehicle. Similarly, in the fixed state, the first folding points P12 and P13 of each of the first electric wires 11b and 11c are closer to the vehicle than the first connectors 15b and 15c to which the first electric wires 11b and 11c are electrically connected, respectively. in the up-down direction. Similarly, in the fixed state, the second return point P14 of the second electric wire 11d is located below the second connector 15d to which the second electric wire 11d is electrically connected in the vertical direction of the vehicle. In the fixed state, each of the water draining portions 16a to 16d is curved so as to protrude downward in the vertical direction of the vehicle.

Water droplets may adhere to the surface of the electric wire 11 when the electric wire 11 is exposed to liquid such as rainwater or dew condensation occurs on the surface of the electric wire 11 . For example, water droplets adhering to the first electric wire 11a move along the surface of the first electric wire 11a to near the first turning point P11 located below. After that, the water droplet falls from the first electric wire 11a near the first turn-around point P11 of the first electric wire 11a. Therefore, water droplets adhering to the surface of the first electric wire 11a are prevented from reaching the first connector 15a along the surface of the first electric wire 11a. Similarly, when water droplets adhere to the surfaces of the first electric wires 11b, 11c and the second electric wire 11d, the water droplets adhered to the electric wires 11b to 11d move downward along the surfaces of the electric wires 11b to 11d. After that, the water droplets fall from the vicinity of the turning points P12 to P14 of the electric wires 11b to 11d, respectively. Thus, the draining function is exhibited in the draining portions 16a to 16d.

Effects of the present embodiment will be described.
(1) The wire harness 10 includes at least one electric wire 11 having one end electrically connected to the connector 15 , and the housing 14 holding the connector 15 and fixed to the first fixing target 61 . ing. The wire harness 10 also includes a regulating member 12 that has greater rigidity than the electric wire 11 and is arranged along the direction in which the electric wire 11 extends and is fixed to the electric wire 11 so as not to move relative to the electric wire 11 . Furthermore, the wire harness 10 includes a fixing member 13 that is attached to the electric wire 11 and the restricting member 12 so as not to move relative to each other, and is fixed to a second fixing target 62 that has a fixed positional relationship with the first fixing target 61. there is Each electric wire 11 has a fixing start point P1 where fixing to the regulating member 12 starts when each electric wire 11 traces from one end of each electric wire 11 to which the connector 15 is electrically connected to the other end. ~P4. When the housing 14 is fixed to the first fixed target 61 and the fixed member 13 is fixed to the second fixed target 62, each electric wire 11 is fixed at the fixing start points P1 to P4 of each electric wire 11 and each electric wire 11 Each electric wire 11 has folding points P11 to P14 at portions between it and the connector 15 electrically connected to it. Among both ends of the regulating member 12 in the direction in which the electric wire 11 extends, the end facing the connector 15 along the direction in which the electric wire 11 extends is the first end 12a, and the end of the regulating member 12 opposite to the first end 12a is the second end. 12b. Further, the direction from the second end 12b to the first end 12a is defined as a reference direction X1. In the fixed state, the positions of the folding points P11 to P14 in the reference direction X1 are forward in the reference direction X1 from the connector 15 electrically connected to the electric wire 11 having the folding points P11 to P14.

According to this configuration, when the wire harness 10 is arranged such that the folding point P11 is positioned vertically below the connector 15 to which the wire 11 having the folding point P11 is electrically connected, the wire Water droplets adhering to the surface of wire 11 move downward along the surface of wire 11 . Then, the water droplet separates from the electric wire 11 near the turning point P11 of the electric wire 11 and falls. Thus, the portion of the electric wire 11 between the fixing start point P1 and the connector 15 functions as a draining portion 16 a that prevents water droplets adhering to the electric wire 11 from reaching the connector 15 . Similarly, for each electric wire 11 having folding points P12 to P14, the portion between the fixing start points P2 to P4 of each electric wire 11 and the connector 15 suppresses water droplets adhering to the electric wire 11 from reaching the connector 15. They function as drainers 16b to 16d.

The positional relationship between the first fixed target 61 and the second fixed target 62 is constant. Therefore, in the fixed state, the positional relationship between the housing 14 and the fixed member 13 is constant. Moreover, since the restricting member 12 is fixed to the electric wire 11 so as not to be relatively movable, the positional relationship with the electric wire 11 is constant. Furthermore, since the fixing member 13 cannot move relative to the electric wire 11 and the restricting member 12, the positional relationship with the electric wire 11 and the restricting member 12 is constant. For these reasons, in the fixed state, the connector 15 held by the housing 14 and the fixing start points P1 to P4 have a fixed positional relationship. As a result, the length of the portion between the fixed start points P1 to P4 of each electric wire 11 and the connector 15 electrically connected to each electric wire 11 does not change. When each electric wire 11 has folding points P11 to P14 in a fixed state, each folding point P11 to P14 corresponds to the fixing starting points P1 to P4 of each electric wire 11 and the connector 15 electrically connected to each electric wire 11. located in the part between Therefore, by fixing the housing 14 to the first fixed target 61 and fixing the fixing member 13 to the second fixed target 62, the fixing start points P1 to P4 of the electric wires 11 and the electric wires 11 are electrically connected. Folding points P11 to P14 located forward of the connector 15 in the reference direction X1 are formed in the portion between the connector 15 and the connector 15. As shown in FIG.

Moreover, the regulation member 12 is fixed to the electric wire 11 . Therefore, in a wire harness mounted on a product that has already been mass-produced, the restricting member 12 can be fixed to the electric wire without changing the shape of the housing 14 . For example, in a wire harness mounted on a vehicle of a model that has already been mass-produced, the restricting member 12 can be fixed to the electric wire without changing the shape of the housing 14 . After fixing the regulating member 12 to the electric wire of the wire harness mounted on the vehicle of the vehicle type which has already been mass-produced, the wire harness can be easily provided with a draining part by fixing the wire harness. Therefore, it is possible to easily provide the water draining portion even for vehicles of vehicle types that have already been mass-produced.

Moreover, when mounting a wire harness including the housing 14 on a vehicle, generally, the housing 14 is fixed to the first fixed object 61 and the electric wire 11 is fixed to the second fixed object 62 . Therefore, in many cases, the wire harness originally includes the fixing member 13 . Therefore, if the fixing member 13 originally provided in the wire harness is attached not only to the electric wire 11 but also to the restricting member 12, there is no need to newly add the fixing member 13. - 特許庁In this case, it is possible to more easily provide the water draining portion even for vehicle models that have already been mass-produced.

(2) The fixing member 13 has a tightening portion 42 that collectively surrounds and tightens the electric wire 11 and the restricting member 12 . According to this configuration, the fixing member 13 can be easily attached to the wire 11 and the restricting member 12 by the tightening portion 42 so as not to move relative to each other.

(3) The wire harness 10 has a plurality of electric wires 11 . The fixing starting points closest to the first end 12a are first fixing starting points P1 to P3, and the electric wires 11 having the first fixing starting points P1 to P3 are first electric wires 11a to 11c. The plurality of electric wires 11 includes a second electric wire 11d different from the first electric wires 11a-11c. In the fixed state, the first electric wires 11a-11c have turn points P11-P13, respectively. The second electric wire 11 d has a branch line 22 branched from the portion of the electric wire 11 fixed to the regulating member 12 . The fixing starting point of the second electric wire 11d is defined as a second fixing starting point P4. The second fixed start point P4 is positioned between the second end 12b and the first fixed start points P1 to P3 in the reference direction X1, and is positioned at the base end of the branch line 22. As shown in FIG. A connector 15 is electrically connected to the tip of the branch line 22 .

According to this configuration, the branch line 22 branches from the portion of the electric wire 11 fixed to the restricting member 12 . Therefore, in the fixed state, the position of the proximal end of the branch line 22 is easily fixed.
(4) In the fixed state, the second electric wire 11d has a second folding point P14. In the fixed state, the position of the second folding point P14 in the reference direction X1 is forward of the connector 15 electrically connected to the tip of the branch line 22 in the reference direction X1.

According to this configuration, the second turn-around point P14 is positioned between the second fixing start point P4 of the second electric wire 11d and the connector 15 electrically connected to the second electric wire 11d. The second fixed starting point P4 is positioned at the proximal end of the branch line 22. As shown in FIG. Furthermore, a connector 15 is electrically connected to the tip of the branch line 22 . Therefore, the second turning point P14 is located on the branch line 22. As shown in FIG. Therefore, if the housing 14 is fixed to the first fixed target 61 and the fixing member 13 is fixed to the second fixed target 62 , the branch line 22 has more power than the connector 15 electrically connected to the branch line 22 . A second turn-around point P14 is formed on the front side in the reference direction X1. Therefore, in the fixed state, the branch wire 22 can function as a draining portion 16d that prevents water droplets adhering to the second wire 11d from reaching the connector 15. As shown in FIG.

(5) The wire harness 10 has the first tape member 31 for fixing the branch wire 22 in a branched state from the portion of the electric wire 11 extending along the restricting member 12 . Furthermore, the wire harness 10 has a second tape member 32 that fixes the restricting member 12 to the electric wire 11 .

According to this configuration, the second tape member 32 is a tape member different from the first tape member 31 that fixes the branch line 22 in a branched state. Therefore, the wire harness 10 can be manufactured more easily than when the tape member for fixing the branch line 22 in a branched state and the tape member for fixing the regulation member 12 to the electric wire 11 are the same tape member. .

(6) The wires 11a to 11c having the fixed start points P1 to P3 closest to the first end 12a among the fixed start points P1 to P4 have turn points P11 to P13, respectively, in the fixed state. Further, in the fixed state, the positions of the turning points P11 to P13 of the electric wires 11a to 11c in the reference direction X1 are forward of the housing 14 in the reference direction X1.

According to this configuration, the wire harness 10 is arranged such that the turn-back points P11 to P13 of the electric wires 11a to 11c are located vertically below the connector 15 to which the electric wires 11a to 11c are electrically connected. When this is done, it is possible to prevent water droplets that have separated from the electric wires 11a to 11c and fallen near the turning points P11 to P13 of the electric wires 11a to 11c from adhering to the housing . Therefore, it is possible to further prevent water droplets from reaching the connector 15 .

(7) The regulating member 12 has a rod shape extending linearly. According to this configuration, the restricting member 12 has a simple shape of a linearly extending bar. Therefore, the regulation member 12 can be manufactured easily. Moreover, it is easy to fix the regulation member 12 to the electric wire 11 .

(8) In the fixed state, the positions of the respective first fixing start points P1 to P3 in the reference direction X1 are on the front side of the housing 14 in the reference direction X1. According to this configuration, the turn-around points P11 to P14 of the electric wires 11a to 11c can be easily provided at positions forward of the housing 14 in the reference direction X1 in the fixed state.

(9) A method for manufacturing a wire harness 10 including a plurality of electric wires 11 having one end electrically connected to a connector 15, and a housing 14 that holds the connector 15 and is fixed to the first fixing target 61. is. The manufacturing method includes an alignment step of aligning a plurality of electric wires 11 so as to form a trunk line 21 and branch lines 22 branching from the trunk line 21 . In this manufacturing method, after the alignment process, the first tape member 31 is wound around the portion where the branch line 22 diverges from the trunk line 21 and the base end region of the branch line 22 to fix the branch line 22 in a branched state from the trunk line 21. A first fixing step is provided. In this manufacturing method, after the first fixing step, the regulating member 12 having rigidity greater than that of the electric wire 11 is arranged in the region including the branched portion of the branch wire 22 of the main wire 21, and then the 2. A second fixing step of winding the tape member 32 around the main line 21 and the regulating member 12 collectively to fix the regulating member 12 to the main line 21 so as not to move relative to each other. In the manufacturing method, after the second fixing step, the fixing member 13 fixed to the second fixing target 62 having a fixed positional relationship with the first fixing target 61 is made immovable relative to the electric wire 11 and the regulating member 12. It has a mounting process for mounting. The manufacturing method includes a connector holding step of holding the connector 15 on the housing 14 .

According to this configuration, in the first fixing step, the second fixing step is performed after fixing the branch line 22 in a branched state from the main line 21 by the first tape member 31 . Therefore, when performing the second fixing step, the branch line 22 is kept branched from the trunk line 21 . Therefore, the operation of winding the second tape member 32 around the trunk line 21 and the regulation member 12 to fix the regulation member 12 to the trunk line 21 can be easily performed.

(10) The wire harness 10 is formed with draining portions 16a to 16d in a fixed state. Therefore, there is no need to worry about deformation of the draining portions 16a to 16d when the wire harness 10 is transported. In addition, even if a surrounding object is caught in the portion forming the draining portions 16a to 16d of the electric wire 11 after the wire harness 10 is assembled to the vehicle body, the length of the portion forming the draining portions 16a to 16d of the electric wire 11 is not sufficient. Hard to change. Therefore, the draining function of the wire harness 10 is prevented from being impaired.

This embodiment can be implemented with the following modifications. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
- In the manufacturing method of the wire harness 10 of the said embodiment, the connector holding process is performed after the mounting process. However, the connector holding step may be performed immediately before any one of the aligning step, the first fixing step, the second fixing step and the mounting step.

- The shape of the regulating member 12 is not limited to a linearly extending rod shape. The regulating member 12 may have any shape as long as it can suppress deformation of the portion of the electric wire 11 fixed to the regulating member 12 . For example, the regulating member 12 may have a non-linear shape such as a curved shape or a wavy shape when viewed in a direction orthogonal to the reference direction X1.

- In the fixed state, the positions of the first fixing start points P1 to P3 in the reference direction X1 may be on the rear side in the reference direction X1 from the end of the housing 14 in the reference direction X1. However, the position of the first folding point P11 in the reference direction X1 is forward of the first connector 15a in the reference direction X1. Similarly, the positions of the first turn-back points P12 and P13 in the reference direction X1 are also forward of the first connectors 15b and 15c in the reference direction X1.

- In the fixed state, if the position of the first folding point P11 in the reference direction X1 is forward of the first connector 15a in the reference direction X1, then the end of the housing 14 in the reference direction X1 is positioned in the reference direction X1. It may be on the rear side. The same applies to the positions of the first turn-back points P12 and P13 in the reference direction X1.

- The wire harness 10 may not include the first tape member 31 .
- The member which fixes the regulation member 12 to the electric wire 11 relatively non-movably is not restricted to the 2nd tape member 32. As shown in FIG. For example, the restricting member 12 may be fixed to the electric wire 11 by a binding band so as not to move relative to each other.

- In the fixed state, the second electric wire 11d may not have the second folding point P14. For example, the branch line 22 may extend linearly from the second fixed starting point P4 to the second connector 15d. Also, the position of the second fixing start point P4 in the reference direction X1 may be the same position as the second connector 15d or may be on the rear side of the second connector 15d in the reference direction X1.

- The branch line 22 may branch from a portion of the main line 21 to which the restricting member 12 is not fixed.
- The wire harness 10 may have a plurality of second electric wires 11 d having branch wires 22 . When the wire harness 10 has a plurality of second electric wires 11d having branch wires 22, the position of the second fixing start point of each second electric wire 11d may be shifted in the reference direction X1. Moreover, the wire harness 10 does not necessarily have to include the second electric wire 11d as long as it includes at least one first electric wire.

- The fixing member 13 may not have the tightening portion 42 . For example, instead of the tightening portion 42, the fixing member 13 may have a mounting portion extending from the base portion 41 in the direction along the reference direction X1. In this case, the wire harness 10 has a binding member that collectively binds the mounting portion, the electric wire 11 and the restricting member 12 . Examples of binding members include adhesive tapes and binding bands. By binding the mounting portion together with the electric wire 11 and the regulating member 12 by the binding member, the fixing member 13 having the mounting portion is mounted on the electric wire 11 and the regulating member 12 so as not to move relative to each other.

- The wire harness 10 may have a plurality of fixing members 13 .
- In the above-described embodiment, the wire harness 10 has three first electric wires 11a to 11c. However, the wire harness 10 only needs to have at least one first electric wire.

- The shape of the housing 14 is not limited to that of the above embodiment as long as it can hold the connector 15 . Also, the method by which the housing 14 holds the connector 15 is not limited to the shape of the above embodiment. For example, the housing 14 may hold the connector 15 by sandwiching the connector 15 .

- The first fixed target 61 is not limited to a part of the vehicle body panel. The first fixed object 61 may be, for example, something that the vehicle body has other than the vehicle body panel. For example, the first fixed object 61 may be a bracket fixed to the vehicle body panel. The same applies to the second fixed target 62 as well.

- In the wire harness 10 of the above-described embodiment, one end of each electric wire 11 is directly electrically connected to the connector 15 held in the housing 14 . However, each wire 11 has a wire-side connector electrically connected to one end of each wire 11 and is electrically connected to a connector 15 held in a housing 14 . It may be electrically connected to the connector 15 via.

Technical ideas that can be grasped from the above embodiment and modifications will be described.
