Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the wire harness as described above, there is a large space between the rear end portion of the connector and the protector, so that the wire is allowed to extend in a diagonal direction rearward from the rear end portion of the connector. Therefore, there is a risk that a large force is applied to the rear end portion of the connector from the wire, particularly when the wire is a thick wire for high voltage. This causes, for example, deformation of the water stop rubber interposed between the connector housing of the connector and the wire, and ultimately deteriorates the water tightness of the connector.

[0005] An object of the present disclosure is to provide a wire harness and a protector capable of suppressing a large force from being applied to the rear end portion of the connector from the wire.

Means for Solving the Problems

[0006] The wire harness of the present disclosure comprises a wire harness with a connector having a connector and a wire led out in a rearward direction from the connector, and a protector having a mounting portion attached to the connector and a curved portion that contacts the wire and curves the wire so that it is led out in a direction different from the rearward direction, wherein the protector comprises a first mounting portion that constitutes at least a part of the mounting portion, a first rearward extension portion that extends from the first mounting portion in the rearward direction, and a first curved portion that extends from the first rearward extension portion so as to contact the outer diameter side of the curved portion of the wire and constitutes at least a part of the curved portion, and a cable tie that is passed through a band hole provided in the first cover and fastens the first cover and the wire so that the wire extends in the rearward direction from the connector. [Effects of the Invention]

[0007] The wire harness and protector of this disclosure can prevent excessive force from being applied to the rear end of the connector by the electric wire. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The wire harness in this disclosure is [1] A wire with a connector having a connector and a wire led out in the rear direction from the connector, and a protector having a mounting portion attached to the connector and a curved portion that contacts the wire and curves the wire so that it is led out in a direction different from the rear direction, wherein the protector has a first cover and a cable tie, the first cover having a first mounting portion that constitutes at least a part of the mounting portion, a first rear extension portion that extends from the first mounting portion in the rear direction, and a first curved portion that extends from the first rear extension portion so as to contact the outer diameter side of the curved portion of the wire and constitutes at least a part of the curved portion, and the cable tie fastens the first rear extension portion and the wire so that the wire extends from the connector in the rear direction.

[0010] In this configuration, the first rear extension and the wire are secured together by a cable tie so that the wire extends backward from the connector. Therefore, the wire can be directed backward from the connector without rattling. Thus, it is possible to effectively suppress the application of a large force from the wire to the rear end of the connector.

[0011] [2] In the above [1], the protector has a second cover, the second cover having a second mounting portion which constitutes a part of the mounting portion, a second rear extension which extends from the second mounting portion in the rearward direction and, together with the first rear extension, restricts the path of the electric wire so that the electric wire extends from the connector in the rearward direction, and a second curved portion which extends from the second rear extension along the inner diameter side of the curved portion of the electric wire and constitutes a part of the curved portion.

[0012] According to this configuration, the first and second extensions restrict the path of the wire so that it extends backward from the connector. Therefore, even if the cable tie loosens, for example, it is possible to prevent a large force from being applied from the wire to the rear end of the connector. In addition, the second cover protects the inner diameter side of the curved portion of the wire.

[0013] [3] In [1] or [2] above, the first cover may have a band hole for passing the binding band. According to this configuration, since the first cover has a band hole for passing the binding band, the first rear extension and the electric wire can be suitably bound while preventing the displacement of the binding band.

[0014] [4] In any one of [1] to [3] above, a plurality of electric wires may be arranged in parallel, and the binding band may be provided for each electric wire. According to this configuration, since the binding band is provided for each electric wire, each of the electric wires can be firmly bound to the first rear extension.

[0015] [5] In any one of [1] to [3] above, a plurality of electric wires are arranged in parallel, and one binding band may be provided for the plurality of electric wires, and one binding band may bind the plurality of electric wires and the first rear extension.

[0016] According to this configuration, since one binding band binds the plurality of electric wires and the first rear extension, for example, the number of components can be reduced as compared with the case where the binding band is provided for each electric wire. [6] In any one of [1] to [5] above, the connector may include a connector housing that houses an end portion of the electric wire, and a water-stop rubber interposed between the connector housing and the electric wire at a rear end portion of the connector housing.

[0017] According to this configuration, since the connector has a water-stop rubber interposed between the connector housing and the electric wire at the rear end portion of the connector housing, it is possible to suppress a large force from being applied to the water-stop rubber from the electric wire at the rear end portion of the connector. Therefore, the deformation of the water-stop rubber can be suppressed, and thus the water-tightness of the connector can be ensured well.

[0018] The protector of the present disclosure [7] A protector having an attachment portion attached to the connector in a wire with a connector having a connector and a wire led out rearward from the connector, and a bending portion that contacts the wire to bend the wire in a drawing direction different from the rearward direction, the protector having a first cover and a binding band, the first cover having a first attachment portion that constitutes at least a part of the attachment portion, a first rearward extension portion extending rearward from the first attachment portion, and a first bending portion extending from the first rearward extension portion to contact the outer diameter side of the curved portion of the wire and constituting at least a part of the bending portion, and the binding band binding the first rearward extension portion and the wire so that the wire extends rearward from the connector.

[0019] According to the same configuration, the binding band binds the first rearward extension portion and the wire so that the wire extends rearward from the connector. Therefore, the wire can be directed rearward from the connector without rattling. Therefore, it is possible to preferably suppress a large force being applied to the rear end portion of the connector from the wire.

[0020] [Details of the Embodiment of the Present Disclosure] A specific example of the wire harness 11 of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be exaggerated or simplified. Also, the dimensional ratios of each part may be different in each drawing. "Parallel", "orthogonal", and "true circle" in this specification include not only the cases of being exactly parallel, orthogonal, or a true circle, but also the cases that are generally parallel, orthogonal, or a true circle within the range where the operational effects of the present embodiment are achieved. Note that the present invention is not limited to these examples, and is shown by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included.

[0021] (Configuration of Wire Harness 11) As shown in Figures 1 and 2, the wire harness 11 comprises a wire with a connector 12 and a protector 13. The wire harness 11 is a high-voltage component used to electrically connect electrical equipment such as inverters and high-voltage batteries installed in hybrid vehicles and electric vehicles, for example. The figures show a first axis X, a second axis Y perpendicular to the first axis X, and a third axis Z perpendicular to both the first axis X and the second axis Y. The figures also show a rearward direction X1, which is one direction in the front-rear direction along the first axis X, and an outward direction Y1, which is one direction in the up-down direction along the second axis Y.

[0022] (Configuration of the wire with connector 12) As shown in Figures 1 and 2, the wire with connector 12 has a connector 14 and two wires 15 led out from the connector 14 in the rear direction X1.

[0023] As shown in Figures 3 and 4, the electric wire 15 is a covered electric wire having a core wire 15a and an insulating coating 15b covering the outer circumference of the core wire 15a. As the core wire 15a, for example, a stranded wire made by twisting together multiple metal strands or a single-core wire made of a single conductor can be used. As the material of the core wire 15a, for example, a metal material such as copper or aluminum can be used. The insulating coating 15b covers the outer surface of the core wire 15a around its entire circumference. The insulating coating 15b is made of an insulating resin material. The cross-sectional shape of the electric wire 15 is circular.

[0024] As shown in Figure 3, the connector 14 comprises a connector housing 16 and a waterproof rubber seal 17. The connector housing 16 is made of a resin material. The connector housing 16 accommodates and holds the ends of the two electric wires 15. The waterproof rubber seal 17 is interposed between the connector housing 16 and the electric wires 15 at the rear end of the connector housing 16, preventing liquid from entering the inside of the connector housing 16 from the outside. The connector housing 16 also holds connection terminals (not shown) that are connected to the core wires 15a. The connector 14 is configured to be matable with an external connector (not shown), and when the external connector is mated, the connection terminals are connected to the terminals of the external connector.

[0025] (Protector 13 configuration) As shown in Figures 1 and 3, the protector 13 has a mounting portion 18 that is attached to the connector 14 and a curved portion 19 that contacts the electric wire 15 and curves the electric wire 15 so that it is pulled out in a direction Y1 different from the rear direction X1.

[0026] More specifically, as shown in Figures 1 to 5, the protector 13 has a first cover 21, a second cover 22, and cable ties 23. In this embodiment, a cable tie 23 is provided for each wire 15, and the protector 13 has two cable ties 23.

[0027] (Structure of Cover 21) As shown in Figure 3, the first cover 21 has a first mounting portion 24, a first extension portion 25, and a first curved portion 26. The first cover 21 is made of a resin material. The first mounting portion 24 constitutes a part of the mounting portion 18. The first mounting portion 24 is formed to cover half of the outer circumference of the rear end of the connector housing 16 and has locking claws 24a (see Figure 2) at both ends in the circumferential direction.

[0028] The first extension portion 25 extends in the rearward direction X1 from the first mounting portion 24. The first extension portion 25 has two first extension recesses 25a (see Figure 4), the same number as the number of electric wires 15. The cross-sectional shape of the first extension recesses 25a is an arc shape.

[0029] The first curved portion 26 extends from the first extended portion 25 so as to contact the outer diameter side of the curved part of the electric wire 15 and constitutes a part of the curved portion 19. The first curved portion 26 has two first curved recesses 26a, the same number as the electric wires 15. The cross-sectional shape of the first curved recesses 26a is an arc shape. At least a portion of the electric wire 15 will be accommodated in the first extended recess 25a and the first curved recess 26a.

[0030] Furthermore, as shown in Figure 5, the first tip portion 26b of the first curved portion 26 has an engaging groove 26c as an engaging portion. The engaging groove 26c extends along the pulling direction Y1 to the tip of the first curved portion 26. In this embodiment, the engaging groove 26c is provided on both sides of the first tip portion 26b in the direction in which the electric wires 15 are laid side by side (width direction along the third axis Z). More specifically, the engaging groove 26c is provided not only on both sides of the first tip portion 26b in the direction in which the electric wires 15 are laid side by side (width direction along the third axis Z), but also at positions that sandwich each of the electric wires 15. In other words, there is a pair of engaging grooves 26c for each first curved recess 26a and for each electric wire 15, and there are a total of four provided on the first tip portion 26b.

[0031] Furthermore, as shown in Figure 4, the first cover 21 has band holes 27 for passing cable ties 23 through. The band holes 27 penetrate vertically through the first extension 25. There is a pair of band holes 27 for each first extension recess 25a and for each electric wire 15, with a total of four band holes provided in the first extension 25.

[0032] (Structure of Cover 2, Section 22) As shown in Figure 3, the second cover 22 has a second mounting portion 28, a second extension portion 29, and a second curved portion 30. The second cover 22 is made of a resin material. The second mounting portion 28 constitutes a part of the mounting portion 18. The second mounting portion 28 is formed to cover half of the outer circumference of the rear end of the connector housing 16 and has locking pieces 28a (see Figure 2) at both ends in the circumferential direction. The locking pieces 28a of the second mounting portion 28 are locked to the locking claws 24a so that the second mounting portion 28 covers the entire circumference of the rear end of the connector housing 16 together with the first mounting portion 24. As a result, the mounting portion 18, which is composed of the first mounting portion 24 and the second mounting portion 28, is attached to the connector 14 by sandwiching the rear end of the connector housing 16.

[0033] The second extension portion 29 extends in the rearward direction X1 from the second mounting portion 28. The second extension portion 29 has two second extension recesses 29a, the same number as the number of electric wires 15. The cross-sectional shape of the second extension recesses 29a is an arc shape. Together with the first extension portion 25, the second extension portion 29 restricts the path of the electric wires 15 so that they extend in the rearward direction X1 from the connector 14. That is, the first extension recess 25a of the first extension portion 25 and the second extension recess 29a of the second extension portion 29 extend in the rearward direction X1 while surrounding the electric wires 15, thereby restricting the path of the electric wires 15 so that they extend straight in the rearward direction X1 from the connector 14.

[0034] The second curved portion 30 extends from the second extended portion 29 along the inner diameter side of the curved part of the electric wire 15 and forms part of the curved portion 19. The second curved portion 30 has two second curved recesses 30a, the same number as the electric wire 15. The cross-sectional shape of the second curved recess 30a is an arc shape. At least a portion of the electric wire 15 will be accommodated in the second extended recess 29a and the second curved recess 30a. The curved portion 19, formed by the first curved portion 26 and the second curved portion 30, curves around the electric wire 15 and comes into contact with the electric wire 15, causing the electric wire 15 to curve toward the exit direction Y1.

[0035] Furthermore, as shown in Figure 5, the second tip portion 30b of the second curved portion 30 has an engaging projection 30c as an engaging portion. The engaging projection 30c extends along the pulling direction Y1 to the tip of the second curved portion 30. In this embodiment, the engaging projection 30c is provided on both sides of the second tip portion 30b in the direction in which the electric wires 15 are laid side by side (width direction along the third axis Z). More specifically, the engaging projection 30c is provided not only on both sides of the second tip portion 30b in the direction in which the electric wires 15 are laid side by side (width direction along the third axis Z), but also at positions that sandwich each of the electric wires 15. In other words, there is a pair of engaging projections 30c for each second curved recess 30a and for each electric wire 15, and there are a total of four on the second tip portion 30b. The engaging projection 30c fits into the engaging groove 26c when the second cover 22 is moved upward relative to the first cover 21. As a result, the engaging projection 30c engages with the engaged groove 26c in the front-rear direction. By engaging with the engaged groove 26c, the engaging projection 30c suppresses deformation of the first tip portion 26b in the rearward direction X1. That is, although the first tip portion 26b may be subjected to a large force in the rearward direction X1 from the curved electric wire 15, the engagement of the engaging projection 30c with the engaged groove 26c suppresses deformation of the first tip portion 26b in the rearward direction X1. In addition, the first tip portion 26b and the second tip portion 30b are prevented from separating and opening up in the front-rear direction.

[0036] (Configuration of cable tie 23) As shown in Figures 3 and 4, the cable tie 23 fastens the first rear extension 25 of the first cover 21 and the electric wire 15 so that the electric wire 15 extends in the rear direction X1 from the connector 14. Specifically, the cable tie 23 has a flexible, supple strip-shaped portion 23a and a locking portion 23b provided at the longitudinal end of the strip-shaped portion 23a. The locking portion 23b locks the strip-shaped portion 23a by restricting its movement in the opposite direction to the direction of passing it through, i.e., in the direction of pulling it out, while the strip-shaped portion 23a is passing through two band holes 27 and covering the first rear extension 25 and the electric wire 15. A cable tie 23 is provided for each wire 15, and each wire 15 is secured to the first extension portion 25. As a result, the wire 15 is in close contact with the first extension recess 25a of the first extension portion 25. That is, the wire 15 is interposed with a small gap between the first extension recess 25a and the second extension recess 29a, but is positioned to be in close contact with the first extension recess 25a. As a result, the wire 15 is maintained in a state where it extends straight toward the rear X1 without rattling.

[0037] Next, a method for manufacturing the wire harness 11 configured as described above and its operation will be explained. The method for manufacturing the wire harness 11 includes a bundling step of bundling the first extension 25 and the electric wire 15 with a cable tie 23 before assembling the second cover 22 to the first cover 21, and an assembly step of assembling the second cover 22 to the first cover 21 after the bundling step.

[0038] In this way, by first securing the first extension 25 and the electric wire 15 with the cable tie 23, the assembly of the second cover 22 to the first cover 21 becomes easier. That is, if the electric wire 15 is not secured to the first extension 25 by the cable tie 23, the electric wire 15 may be positioned so as to float above the first extension recess 25a of the first cover 21, potentially creating resistance to the assembly of the second cover 22. In contrast, if the electric wire 15 is secured to the first extension 25 by the cable tie 23, the electric wire 15 is in contact with the first extension recess 25a, thus not creating resistance to the assembly of the second cover 22, and improving the ease of assembly of the second cover 22 to the first cover 21. With the protector 13 attached to the connector-equipped electric wire 12 in this way, the electric wire 15 first extends in the rearward direction X1 from the connector 14, and then curves and is pulled out in the outward direction Y1.

[0039] Next, the effects of the above embodiment are described below. (1) The protector 13 has a cable tie 23. The cable tie 23 fastens the first rear extension 25 and the electric wire 15 so that the electric wire 15 extends in the rear direction X1 from the connector 14. This allows the electric wire 15 to be directed in the rear direction X1 from the connector 14 without rattling. This effectively prevents a large force from being applied to the rear end of the connector 14 by the electric wire 15. In addition, for example, vibration of the electric wire 15 can be suppressed inside the protector 13.

[0040] Since the connector 14 has a waterproof rubber 17 interposed between the connector housing 16 and the electric wire 15 at the rear end of the connector housing 16, it is possible to suppress the application of a large force from the electric wire 15 to the waterproof rubber 17 at the rear end of the connector 14. Therefore, deformation of the waterproof rubber 17 can be suppressed, and consequently, good watertightness of the connector 14 can be ensured.

[0041] (2) The protector 13 has a second cover 22. The first rear extension 25 and the second rear extension 29 restrict the path of the electric wire 15 so that it extends in the rear direction X1 from the connector 14. Therefore, even if the cable tie 23 loosens, for example, it is possible to prevent a large force from being applied from the electric wire 15 to the rear end of the connector 14. The second cover 22 also protects the inner diameter side of the curved portion of the electric wire 15. Furthermore, in the configuration with the second cover 22, the assembly of the second cover 22 to the first cover 21 becomes easier by first securing the first rear extension 25 and the electric wire 15 with the cable tie 23. In other words, the cable tie 23 plays a role in improving the ease of assembly of the second cover 22.

[0042] (3) The first cover 21 has a band hole 27 for passing the cable tie 23 through, so that the first extension 25 and the electric wire 15 can be suitably fastened together while preventing the cable tie 23 from shifting position.

[0043] (4) Since a cable tie 23 is provided for each wire 15, each wire 15 can be firmly bound to the first extension 25. This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0044] In the above embodiment, the cable tie 23 is provided for each electric wire 15, but the invention is not limited to this, and one cable tie 23 may be used to fasten multiple electric wires 15 and the first extension 25 together.

[0045] For example, as shown in Figure 6, one cable tie 23 may be provided for every two wires 15, and one tie may be used to fasten both wires 15 and the first extension 25. In this example, the cable tie 23 fastens the first extension 25 and the two wires 15 by passing the strip portion 23a through all four band holes 27 and covering the first extension 25 and the two wires 15 before passing it through the lock portion 23b. This reduces the number of parts compared to the case where a cable tie 23 is provided for each wire 15.

[0046] In the above embodiment, the engaged portion and the engaging portion are an engaged groove 26c and an engaging projection 30c extending along the pulling direction Y1, but the embodiment is not limited to this, and may be changed to, for example, an engaged hole and an engaging claw that catches on the engaged hole. Conversely, the engaging portion may be an engaging groove and the engaged portion may be an engaged projection.

[0047] In the above embodiment, the engaging grooves 26c and engaging projections 30c are provided not only on both sides in the parallel arrangement direction of the multiple electric wires 15 at the first tip portion 26b and the second tip portion 30b, but also at positions that sandwich each of the electric wires 15. However, the embodiment is not limited to this, and the position and number may be changed. For example, the engaging grooves 26c and engaging projections 30c may be provided only on both sides in the parallel arrangement direction of the multiple electric wires 15 at the first tip portion 26b and the second tip portion 30b. Alternatively, for example, the engaging grooves 26c and engaging projections 30c may be provided only in the middle of the parallel arrangement direction of the multiple electric wires 15 at the first tip portion 26b and the second tip portion 30b.

[0048] In the above embodiment, the protector 13 is shown to have a second cover 22, but it is not limited to this, and may not have a second cover 22. In this case, the first mounting portion 24 of the first cover 21 needs to be modified to a configuration that allows it to be attached to the connector 14 independently, regardless of the second mounting portion 28.

[0049] In the above embodiment, the first tip portion 26b of the first curved portion 26 has an engagement groove 26c, and the second tip portion 30b of the second curved portion 30 has an engagement projection 30c. However, the embodiment is not limited to this, and the engagement groove 26c and the engagement projection 30c may not be present.

[0050] In the above embodiment, the first cover 21 is provided with a band hole 27 for passing the cable tie 23 through, but it is not limited to this, and it may be configured without a band hole 27. In this case, for example, the cable tie 23 may be used to fasten the entire first cover 21 to the electric wire 15 without passing it through the band hole 27.

[0051] In the above embodiment, the connector 14 is assumed to have a watertight rubber 17 interposed between the connector housing 16 and the electric wire 15, but it is not limited to this, and a configuration without the watertight rubber 17 is also possible. Even in this case, it is possible to suppress the application of a large force from the electric wire 15 to the rear end of the connector 14, thereby suppressing damage to the connector housing 16, for example.

[0052] In the above embodiment, the rearward direction X1 and the exit direction Y1 of the electric wire 15 are assumed to be orthogonal directions, but the invention is not limited to this, and the exit direction Y1 may be in a different direction from the rearward direction X1.

[0053] In the above embodiment, the wire 12 with a connector has two wires 15, but it is not limited to this, and it may have only one wire 15, or it may have three or more wires 15. [Explanation of Symbols]
