Description

[Technical Field]

[0001] The present invention relates to a wire harness. [Background technology]

[0002] A conventional wire harness is disclosed in Patent Document 1. This wire harness includes a wire harness body, a connection terminal, and a waterproof member.

[0003] The connection terminal is provided at one end of the wire harness body, and the waterproof member is attached to the wire harness body along the extension thereof.

[0004] The watertight member has a mounting portion that is mounted around the wire harness body and an expanded diameter portion whose base end is connected to the mounting portion. The expanded diameter portion expands in diameter toward its tip and protrudes beyond the outer periphery of the wire harness body.

[0005] In this wire harness, water running down the wire harness main body is caught by the enlarged diameter portion of the watertight member along the way, which prevents the water running down the wire harness main body from flowing downstream of the watertight member, thereby preventing the water running down the wire harness main body from entering the connection terminal provided at one end of the wire harness main body.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-143798 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the conventional wire harnesses, the waterproofing member is provided as a separate component, which increases the number of components and increases costs. In addition, the waterproofing member is made of elastomer and is an integrally molded component of the mounting portion and the enlarged diameter portion, making its manufacture cumbersome.

[0008] The present invention has been made in view of the above-described conventional circumstances, and an object to be achieved is to provide a wire harness that can be manufactured inexpensively and easily. [Means for solving the problem]

[0009] The wire harness of the present invention comprises: a wire harness main body; a connection terminal provided at one end of the wire harness main body; a label attached to the wire harness main body at a position adjacent to the connection terminal and displaying information about the wire harness main body; and a wire harness to be routed in a specific posture inside a vehicle, The label has a covering portion that covers an outer peripheral surface of the wire harness main body and an extending portion that extends integrally from the covering portion, In the wire harness in the specific position, the extension portion extends downward from the covering portion.

[0010] In the wire harness of the present invention, the label attached to the wire harness main body at a position adjacent to the connection terminal has a covering portion that covers the outer peripheral surface of the wire harness main body and an extending portion that extends integrally from the covering portion. Moreover, when the wire harness is routed in a vehicle in a specific posture, the extending portion extends downward from the covering portion.

[0011] With this configuration, when water adhering to the wire harness main body flows down the wire harness main body and reaches the label, the water is guided from the outer peripheral surface of the wire harness main body through the covering portion to the extension portion, and then flows down along the extension portion and falls from the extension portion. This prevents water flowing down the wire harness main body from reaching the wire harness main body downstream of the label. As a result, water flowing down the wire harness main body can be prevented from entering the connection terminal provided at one end of the wire harness main body.

[0012] In this way, with this wire harness, the waterproof function is provided in the label that is usually attached to the wire harness body, so there is no need to add a waterproof member as a separate part, and the label itself is easy to manufacture.

[0013] Therefore, the wire harness of the present invention can be manufactured inexpensively and easily.

[0014] The label may have a rectangular substrate having information displayed on a first surface thereof and an adhesive layer provided on a second surface of the substrate facing away from the first surface. The substrate may have a first end located on one end of the rectangular shape, a second end located on the other end of the rectangular shape, and an intermediate portion located between the first end and the second end. The covering portion may be formed by wrapping the intermediate portion around the wire harness main body, and the extension portion may be formed by overlapping the first end and the second end. Preferably, the adhesive layer seals the outer peripheral surface of the wire harness main body and the second surface.

[0015] In this case, the label can be attached to the wire harness main body by a simple operation. That is, the label can be attached to the wire harness main body by wrapping the intermediate portion of the substrate around the outer peripheral surface of the wire harness main body while overlapping the first and second end portions of the substrate, bonding the intermediate portion of the substrate to the outer peripheral surface of the wire harness main body with the adhesive of the adhesive layer, and bonding the first and second end portions of the substrate with the adhesive of the adhesive layer. Furthermore, since the adhesive layer seals the gap between the outer peripheral surface of the wire harness main body and the second surface of the substrate, it is possible to reliably prevent water running down the outer peripheral surface of the wire harness main body from flowing downstream of the label.

[0016] The label preferably has a protrusion integrally protruding from the covering portion on the opposite side to the extending portion, and the protrusion can be formed by folding the intermediate portion at the center and overlapping the folded portions.

[0017] In this case, the protrusions can block water running down the outer circumferential surface of the wire harness body, thereby more reliably preventing the water from running downstream of the label. Furthermore, when wrapping the intermediate portion of the base material around the outer circumferential surface of the wire harness body, the protrusions can be easily formed by folding the intermediate portion at the center and overlapping the folded portions.

[0018] In the wire harness in the specific position, the wire harness body may have a raised region rising from the connection terminal, and the label attachment position on the wire harness body is preferably in the raised region.

[0019] In this case, water flowing down the rising region of the wire harness main body descends toward the connection terminal, but because the label is attached midway down the rising region, the water flowing down the rising region can be guided from the outer peripheral surface of the wire harness main body to the extension portion via the covering portion. This prevents water flowing down the rising region of the wire harness main body from flowing downstream of the label. As a result, water flowing down the wire harness main body can be prevented from entering the connection terminal provided at one end of the wire harness main body. [Effects of the Invention]

[0022] Hereinafter, first and second embodiments of the present invention will be described with reference to the drawings.

[0023] As shown in Fig. 1, a wire harness 1 of Example 1, which is an example of a specific aspect of the "wire harness" of the present invention, is routed inside a vehicle 10. In this example, the vehicle 10 is an electric vehicle. Note that the vehicle 10 may also be a gasoline vehicle, a hybrid vehicle, or the like.

[0024] The left side of the paper in FIG. 1 is defined as the front of the wire harness 1, and the right side of the paper in FIG. 1 is defined as the rear of the wire harness 1. The up-down direction of the paper in FIG. 1 coincides with the vertical direction. The front-rear and up-down directions shown in FIG. 2 and subsequent figures are all shown corresponding to FIG. 1. Note that these directions are examples for the sake of convenience of explanation, and the posture of the wire harness 1 is changed appropriately depending on the manner in which it is mounted on the vehicle 10. However, the wire harness 1 of this embodiment is routed inside the vehicle 10 in a specific posture in which the wire harness main body 20 rises from the first connection terminal 71, as will be described later.

[0025] The vehicle 10 has a dash panel 11 and an instrument panel 12.

[0026] The dash panel 11 divides the interior of the vehicle 10 into an engine compartment 10a side located in front of the dash panel 11 and a passenger compartment 10b side located behind the dash panel 11.

[0027] The instrument panel 12 is disposed behind the dash panel 11. The compartment 10b is located behind the instrument panel 12. That is, a part of the space on the compartment 10b side behind the dash panel 11 is defined as an instrument panel interior 10c, which is the interior of the instrument panel 12, and the compartment 10b behind the instrument panel interior 10c.

[0028] The engine compartment 10a is equipped with a traction motor (not shown) as a power source for the vehicle 10, and a battery 13. Note that the engine compartment 10a may be equipped with an internal combustion engine instead of the traction motor, or may be equipped with an internal combustion engine together with the traction motor.

[0029] The first electronic device 14, the second electronic device 15, and the wire harness 1 are installed inside the instrument panel 10c. The first electronic device 14 is located lower than the second electronic device 15 inside the instrument panel 10c.

[0030] In this embodiment, the first electronic device 14 is an ECU (electronic control unit, electronic control computer), and the second electronic device 15 is a terminal box. The second electronic device 15 is electrically connected to the battery 13. The wire harness 1 electrically connects the first electronic device 14 and the second electronic device 15.

[0031] The second electronic device 15, which serves as a terminal box, supplies power from the battery 13 to the first electronic device 14 via the wire harness 1. The second electronic device 15 also distributes the power supplied from the battery 13 to various other electronic devices (not shown) mounted on the vehicle 10 via other wire harnesses (not shown). Furthermore, the second electronic device 15 transmits and receives various signals to the first electronic device 14 and the various other electronic devices mounted on the vehicle 10 via other wire harnesses (not shown).

[0032] The wire harness 1 includes a wire harness main body 20, a first connection terminal 71, a second connection terminal 72, and a label 30.

[0033] 3, the wire harness main body 20 has a core 21 made of a conductive material and a coating 22 made of an insulating material. A first connection terminal 71 is connected to one end of the core 21, and a second connection terminal 72 is connected to the other end of the core 21. That is, the first connection terminal 71 is provided at one end of the wire harness main body 20, and the second connection terminal 72 is provided at the other end of the wire harness main body 20. The first connection terminal 71 is connected to a first mating terminal (not shown) provided on the first electronic device 14. The second connection terminal 72 is connected to a second mating terminal (not shown) provided on the second electronic device 15.

[0034] In this manner, the wire harness 1 is connected to the first electronic device 14 and the second electronic device 15 and is routed inside the vehicle 10. As shown in Fig. 1 , the wire harness 1 routed inside the vehicle 10 is in a specific posture in which the wire harness main body 20 rises from the first connection terminal 71 toward the second connection terminal 72. That is, in this specific posture, the entire wire harness main body 20 is in an ascending region in which it rises from the first connection terminal 71 toward the second connection terminal 72.

[0035] The label 30 is attached to the wire harness main body 20 at a position adjacent to the first connection terminal 71. When the wire harness 1 is routed in the vehicle 10 in a specific posture, the wire harness main body 20 is raised from the first connection terminal 71, and therefore the attachment position of the label 30 on the wire harness main body 20 is in the raised region of the wire harness main body 20.

[0036] Here, the position adjacent to the first connection terminal 71 includes a position where the label 30 is close to but separated from the first connection terminal 71, a position where the label 30 is in contact with the first connection terminal 71, and also a position where the distance from the first connection terminal 71 to the label 30 is a predetermined distance L (see FIG. 2). The value of the predetermined distance L can be appropriately set within a range of, for example, 1 cm to 20 cm depending on various conditions such as how easily the wire harness main body 20 is wetted. In this embodiment, the value of L is set to about 1 to 2 cm.

[0037] As shown in FIG. 2, the label 30 has a covering portion 31 and an extending portion 32.

[0038] The covering portion 31 covers the outer peripheral surface 20a of the wire harness main body 20. The entire inner surface of the covering portion 31 is in close contact with the outer peripheral surface 20a of the wire harness main body 20 via an adhesive layer 42 described later, and no gap is provided between the inner surface of the covering portion 31 and the outer peripheral surface 20a of the wire harness main body 20.

[0039] The extension portion 32 extends integrally from the covering portion 31. When the wire harness 1 is in a specific posture, the extension portion 32 extends downward from the covering portion 31. The extension portion 32 also has a display portion 33 that displays information about the wire harness main body 20 and the wire harness 1.

[0040] As shown in FIG. 3, the label 30 has a substrate 41 and an adhesive layer .

[0041] The base material 41 has flexibility and water resistance to such an extent that it can be wrapped around the wire harness main body 20. The base material 41 may be made of paper, but in this embodiment it is made of synthetic resin. Specifically, the base material 41 is made of a resin sheet such as polyester or polyethylene terephthalate. Note that, from the viewpoint of enhancing the water-stopping effect of the label 30, a water-repellent coating layer may be formed on a first surface 41a (described later) of the base material 41, as necessary.

[0042] The thickness of the base material 41 can be set as appropriate, but is preferably as thick as possible within the range in which it can be wound around the wire harness main body 20. If the thickness of the base material 41 in the covering portion 31 is increased, the effect of blocking water flowing down the wire harness main body 20 is improved.

[0043] The base material 41 has a rectangular shape. Specifically, the base material 41 has a strip shape with a length two to three times the circumferential length of the wire harness main body 20. The base material 41 has a first end portion 411 located at one end in the longitudinal direction, a second end portion 412 located at the other end in the longitudinal direction, and an intermediate portion 413 located between the first end portion 411 and the second end portion 412. The covering portion 31 is formed by wrapping the intermediate portion 413 around the wire harness main body 20, and the extending portion 32 is formed by overlapping the first end portion 411 and the second end portion 412. The length of the intermediate portion 413 is set according to the circumferential length of the wire harness main body 20 so that the covering portion 31 is appropriately formed by the intermediate portion 413.

[0044] The substrate 41 has a first surface 41a and a second surface 41b facing away from the first surface 41a.

[0045] The display portion 33 is formed on the first surface 41a of the base material 41. On the display portion 33, information relating to the wire harness main body 20 and the wire harness 1, such as identification information such as a part number and a serial number, and characters and symbols relating to information on a connection partner, etc., are printed.

[0046] The adhesive layer 42 is formed on the second surface 41b of the base material 41. The adhesive layer 42 is laminated with a uniform thickness over the entire second surface 41b. The outer peripheral surface 20a of the wire harness main body 20 and the second surface 41b at the intermediate portion 413 of the base material 41 are bonded together by the adhesive layer 42, and the second surface 41b at the first end portion 411 of the base material 41 and the second surface 41b at the second end portion 412 are bonded together by the adhesive layer 42. As a result, the adhesive layer 42 seals the gap between the outer peripheral surface 20a of the wire harness main body 20 and the second surface 41b of the base material 41, i.e., the gap between the outer peripheral surface 20a of the wire harness main body 20 and the inner surface of the label 30.

[0047] Here, the wire harness 1 may be submerged in water inside the instrument panel 10c, which is inside the vehicle 10 and outside the passenger compartment 10b. In this case, if the wire harness main body 20 is in a specific position in which the first connection terminal 71 is raised, as in this embodiment, water adhering to the wire harness main body 20 may flow down along the wire harness main body 20 and enter the first connection terminal 71. If the first connection terminal 71 is submerged in water, the electrical connection between the first connection terminal 71 and the first mating terminal may corrode, resulting in a poor connection.

[0048] In this regard, in this wire harness 1, the label 30 is attached to the rising region of the wire harness main body 20 of the wire harness 1 in the specific posture. That is, water running down the rising region of the wire harness main body 20 descends toward the first connection terminal 71, and the label 30 is attached midway down the rising region. The covering portion 31 of the label 30 covers the outer peripheral surface 20a of the wire harness main body 20. Moreover, when the wire harness 1 is in the specific posture, the extending portion 32 of the label 30 extends downward from the covering portion 31.

[0049] Therefore, even if the wire harness 1 is submerged in water, once water flowing down the wire harness main body 20 reaches the label 30, the water is guided from the outer peripheral surface 20a of the wire harness main body 20 via the covering portion 31 to the extending portion 32, and then flows down along the extending portion 32 and falls from the extending portion 32. As a result, water that has flowed down the rising region of the wire harness main body 20 can be prevented from reaching the wire harness main body 20 downstream of the label 30, and thus water flowing down the wire harness main body 20 can be prevented from entering the first connection terminal 71.

[0050] Furthermore, if the wire harness main body 20 located between the label 30 and the first connection terminal 71 is exposed to water, the water may infiltrate the first connection terminal 71. In this regard, in the wire harness 1, the label 30 is attached to the wire harness main body 20 at a position close to the first connection terminal 71. More specifically, the distance between the label 30 and the first connection terminal 71 is set to a predetermined distance L of about 1 to 2 cm. Therefore, the wire harness main body 20 located between the label 30 and the first connection terminal 71 is unlikely to be exposed to water. As a result, there is little risk that water adhering to the wire harness main body 20 will infiltrate the first connection terminal 71 due to the wire harness main body 20 located between the label 30 and the first connection terminal 71 being exposed to water.

[0051] Furthermore, in this wire harness 1, since the label 30 has a waterproof function, there is no need to add a waterproof member as a separate component. The label 30 can be prepared by simply changing the size and shape of a label that is originally attached to the wire harness body 20 to display identification information, etc., of the wire harness 1. Therefore, the label 30 itself can be easily manufactured.

[0052] Furthermore, by wrapping the intermediate portion 413 of the substrate 41 around the outer peripheral surface 20a of the wire harness main body 20 while overlapping the first end portion 411 and the second end portion 412 of the substrate 41, the intermediate portion 413 of the substrate 41 and the outer peripheral surface 20a of the wire harness main body 20 are adhered with the adhesive of the adhesive layer 42, and the first end portion 411 and the second end portion 412 of the substrate 41 are adhered with the adhesive of the adhesive layer 42, thereby enabling the label 30 to be attached to the wire harness main body 20 with a simple process.

[0053] Therefore, the wire harness 1 can be manufactured inexpensively and easily.

[0054] In particular, in this wire harness 1, the adhesive layer 42 seals the gap between the outer surface 20a of the wire harness main body 20 and the second surface 41b of the base material 41, so that water running down the outer surface 20a of the wire harness main body 20 can be reliably prevented from spreading downstream of the label 30.

[0055] Example 2 As shown in FIGS. 4 and 5, the wire harness 2 of the second embodiment has a label 50 instead of the label 30 in the wire harness 1 of the first embodiment.

[0056] The label 50 has a covering portion 51, an extending portion 52, and a protruding portion 54. The label 50 also has a base material 61 and an adhesive layer 62. The base material 61 has a first end portion 611 located at one end in the longitudinal direction, a second end portion 612 located at the other end in the longitudinal direction, and an intermediate portion 613 located between the first end portion 611 and the second end portion 612. Compared to the base material 41 in the wire harness 1 of Example 1, the length of the base material 61 in the longitudinal direction is increased by a predetermined amount due to the length of the intermediate portion 613 being increased in order to form the protruding portion 54. The extending portion 52 has a display portion 53 similar to the display portion 33 in the wire harness 1 of Example 1.

[0057] The protrusion 54 protrudes integrally from the covering portion 51 on the side opposite to the extending portion 52. That is, in a specific posture of the wire harness 1 in which the wire harness main body 20 rises from the first connection terminal 71, the protrusion 54 protrudes upward from the covering portion 51.

[0058] The protrusion portion 54 is formed by folding the middle portion 613 in the center and overlapping the folded portion 614, and the covering portion 51 is formed by wrapping the remaining portion of the middle portion 613 around the wire harness main body 20, and the extension portion 52 is formed by overlapping the first end portion 611 and the second end portion 612.

[0059] The base material 61 has a first surface 61a and a second surface 61b facing away from the first surface 61a. The display unit 53 is formed on the first surface 61a of the base material 61. The adhesive layer 62 is formed on the second surface 61b of the base material 61. The adhesive layer 62 is laminated with a uniform thickness over the entire second surface 61b.

[0060] The outer peripheral surface 20a of the wire harness main body 20 and the second surface 61b of the intermediate portion 613 of the substrate 61 other than the folded portion 614 are bonded together by the adhesive layer 62, the second surfaces 61b of the intermediate portion 613 at the folded portions 614 are bonded together by the adhesive layer 62, and the second surface 61b of the first end portion 611 of the substrate 61 and the second surface 61b of the second end portion 612 are bonded together by the adhesive layer 62. As a result, the adhesive layer 62 seals the gap between the outer peripheral surface 20a of the wire harness main body 20 and the second surface 61b of the substrate 61, i.e., the gap between the outer peripheral surface 20a of the wire harness main body 20 and the inner surface of the label 50.

[0061] In this wire harness 2, the water running down the outer peripheral surface 20a of the wire harness main body 20 is blocked by the protrusions 54, so that the water can be prevented from running to the wire harness main body 20 downstream of the label 50 with even higher reliability.

[0062] Furthermore, when the intermediate portion 613 of the base material 61 is wound around the wire harness main body 20, the intermediate portion 613 is bent at the center and the bent portion 614 is overlapped, so that the protrusion 54 can be easily formed.

[0063] The other configurations and effects are the same as those of the first embodiment.

[0064] The present invention has been described above in accordance with Examples 1 and 2, but it goes without saying that the present invention is not limited to the above Examples 1 and 2, and can be modified and applied as appropriate within the scope of the invention.

[0065] For example, in Examples 1 and 2, the wire harness main body 20 has a core 21 made of a conductive material covered with a coating 22 made of an insulating material, but the present invention is not limited to this. The wire harness main body may be, for example, a bundle of electric wires, each of which has a core made of a conductive material covered with a coating made of an insulating material, and the bundle is covered with a tube made of an insulating material. In this case, a connection terminal may be provided at the end of each electric wire.

[0066] In addition, in the first and second embodiments, the wire harness 1 is used to supply power to the first electronic device 14, but the present invention is not limited to this. For example, the wire harness of the present invention may be applied to various signal communications with the first electronic device 14, or the wire harness of the present invention may be applied to both power supply and various signal communications with the first electronic device 14.

[0067] Furthermore, in the first and second embodiments, the wire harness 1 is routed in the interior 10c of the instrument panel 12, which is an internal space of the instrument panel 12 that is a non-wet area inside the vehicle 10 that is unlikely to be splashed with water, but the present invention is not limited thereto. For example, the present invention may be applied to a wire harness routed in a space behind a console box, an internal space of a door panel, or inside a power compartment.

[0068] In addition, in the first and second embodiments, the wire harnesses 1 and 2 connect the ECU as the first electronic device 14 and the terminal box as the second electronic device 15, but the present invention is not limited to this. The present invention can be applied to wire harnesses for connecting various electronic devices mounted on a vehicle to each other, or to wire harnesses for connecting to other wire harnesses. For example, the present invention may be applied to a wire harness for connecting a charging inlet and a battery.

[0069] Furthermore, in Examples 1 and 2, the specific posture is such that the entire wire harness main body 20 is an ascending region, but the present invention is not limited to this. For example, the specific posture may be such that a part of the entire wire harness main body has a descending region or a horizontal region. In this case, assuming that the connection terminal provided at one end of the wire harness main body is the downstream side, the descending region or the horizontal region may be located upstream of the ascending region where the label is attached.

[0070] In Examples 1 and 2, one label 30, 50 is wrapped around the wire harness main body 20, but the present invention is not limited to this. For example, from the viewpoint of improving the waterproofing effect of the label, multiple labels may be wrapped around the wire harness main body in multiple layers to increase the thickness of the covering portion, etc.

[0071] In the first and second embodiments, the labels 30 and 50 attached to the wire harness main body 20 are longer in the direction intersecting the extending direction of the wire harness main body 20 than in the extending direction of the wire harness main body 20, but the present invention is not limited to this. For example, the labels attached to the wire harness main body may be shorter in the direction intersecting the extending direction of the wire harness main body than in the extending direction of the wire harness main body, or may be of the same length in both directions. [Industrial Applicability]

[0072] The present invention can be used in vehicles such as transport vehicles and industrial vehicles in addition to passenger cars. [Explanation of symbols]
