[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes: [1] A wire harness comprising: an electric wire member having an electric wire and a braided member formed by braiding conductive wires; and an earth terminal, wherein the braided member has a tubular portion covering the outer periphery of the electric wire; and an earth wire that is gathered from the end of the tubular portion, extends separably from the electric wire, and is connected to the earth terminal; and the wire harness comprises a holder fixed to the electric wire, and the holder has an earth wire holding portion that holds a part of the extending direction of the earth wire.
[0010] With this configuration, the ground wire holding portion is provided on the holder fixed to the electric wire, so the position of the ground wire relative to the electric wire can be stabilized, which stabilizes the impedance between the tubular portion of the braided member and the ground terminal connected to the ground member, thereby stabilizing the shielding performance.
[0011] [2] In the above [1], the wire harness may further include a tubular outer casing member covering the outer periphery of the electric wire member, and the holder may be attached to an attachment end portion which is one end portion of the outer casing member in the longitudinal direction.
[0012] According to this configuration, the holder having the ground wire holding portion is attached to the attachment end portion, which is one end portion of the exterior member in the longitudinal direction, thereby making it possible to hold the ground wire extending from the braided member near the end portion of the exterior member in the longitudinal direction.
[0013] [3] In the above [2], the holder may include a cylindrical insertion portion inserted into the inside of the outer casing member and a flange portion extending outward from the insertion portion, the electric wire is passed through the inside of the insertion portion, and the flange portion may face the mounting end portion in the longitudinal direction of the outer casing member.
[0014] According to this configuration, the flange portion of the holder can prevent the electric wire from interfering with the mounting end portion of the exterior member. [4] In the above [3], the earth wire holding portion may be formed so as to penetrate the insertion portion in the radial direction, and the earth wire may be passed from the inner side to the outer side of the insertion portion.
[0015] According to this configuration, the earth wire can be passed through the insertion portion of the holder and outwardly of the insertion portion. [5] In the above item [4], the exterior member may have a slit through which the earth wire is passed.
[0016] According to this configuration, the earth wire can be passed through the slit in the exterior member and along the outer periphery of the exterior member. [6] In the above item [5], the earth wire holding portion may have a positioning portion that is inserted into the slit and engages with the slit in the circumferential direction.
[0017] With this configuration, the positioning portion of the ground wire holding portion engages with the slit in the exterior member in the circumferential direction, thereby determining the relative position of the ground wire holding portion and the slit in the exterior member in the circumferential direction, thereby making it possible to determine the position of the slit in the exterior member in the circumferential direction relative to the electric wire member, i.e., the position where the ground wire is drawn out.
[0018] [7] In any of the above [2] to [6], the wire harness may further include a fastening member that fixes the holder to the electric wire, and the holder may have a fixing piece that is fastened and fixed together with the electric wire by the fastening member.
[0019] According to this configuration, the holder is fixed to the electric wire by the fastening member, so that the holder and the earth wire held in the earth wire holding portion of the holder can be held more stably.
[0020] [8] In the above [1], the electric wires may be provided in plurality, the holder may be a cable tie that ties the plurality of electric wires together, the cable tie having a band portion that wraps around the outer circumference of the electric wires, and a lock portion that is integrally formed at the base end of the band portion in the longitudinal direction and into which the band portion is inserted from the tip end to be locked, and the earth wire holding portion may be provided on the lock portion.
[0021] According to this configuration, the position of the ground wire relative to the electric wires can be stabilized by the ground wire holding portion provided on the cable tie that ties together the electric wires. [Details of the embodiments of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for the sake of convenience of explanation, some of the configuration may be exaggerated or simplified. Furthermore, the dimensional proportions of each part may differ from one drawing to another.
[0022] (First embodiment) A first embodiment of the wire harness will be described below. 1 is installed in a vehicle to electrically connect on-board devices provided in the vehicle. The wire harness 10 includes an electric wire member 11, an exterior member 12 that covers the outer periphery of the electric wire member 11, a holder 13 attached to the exterior member 12, and a ground terminal 14.
[0023] (electric wire member 11) The electric wire member 11 has an electric wire 21 and a braided member 22 that covers the outer periphery of the electric wire 21. 2, the wire harness 10 includes, for example, a plurality of electric wires 21. The wire harness 10 of the present embodiment includes, for example, two electric wires 21. The electric wire 21 includes a core wire 23 and an insulating coating 24 that covers the outer periphery of the core wire 23.
[0024] The core wire 23 may be, for example, a stranded wire made by twisting together a plurality of conductive wires, a columnar conductor made of a single columnar metal rod with a solid interior, or a tubular conductor with a hollow interior. The core wire 23 may be, for example, a combination of multiple types of conductors such as a stranded wire, a columnar conductor, and a tubular conductor. Examples of columnar conductors include a single core wire and a bus bar. The material of the core wire 23 may be, for example, a copper-based or aluminum-based metal material.
[0025] The insulating coating 24, for example, covers the entire outer periphery of the core wire 23. The insulating coating 24 is made of an insulating material such as a synthetic resin. For example, a synthetic resin containing a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene as a main component is used as the material for the insulating coating 24. As the material for the insulating coating 24, one type of material may be used alone, or two or more types of materials may be used in appropriate combination.
[0026] (braided member 22) Braided member 22 is made by weaving conductive wires. Each drawing schematically illustrates the state in which the wires of braided member 22 are woven. Braided member 22 can be made of a metal material such as a copper or aluminum material.
[0027] The braided member 22 has a tubular portion 25 that covers the outer periphery of the electric wire 21, and a ground wire 26 that is gathered from an end of the tubular portion 25 in the longitudinal direction and extends separably from the electric wire 21. The tubular portion 25 of this embodiment covers two electric wires 21 together. That is, the braided member 22 of this embodiment is a multi-core lumped shielding member. The ground wire 26 is gathered from an end of the tubular portion 25 in the longitudinal direction and twisted to form a single conductor, and can be bent in a direction different from the extension direction of the electric wires 21.
[0028] (Earth terminal 14) As shown in FIG. 1 , a ground terminal 14 made of a conductor is attached to the tip of the ground wire 26. The ground terminal 14 can be made of, for example, a copper-based or aluminum-based metal material. The ground terminal 14 is electrically connected to the ground wire 26 by, for example, crimping. The ground terminal 14 is electrically connected to a ground member such as a vehicle body panel (not shown) by being fixed to the ground member. As a result, the braided member 22 including the ground wire 26 is grounded to the ground member through the ground terminal 14.
[0029] (Exterior member 12) 1 and 2, the exterior member 12 is formed in a tubular shape that covers the outer periphery of the electric wire member 11. The exterior member 12 protects the electric wire member 11. The exterior member 12 is formed in, for example, a cylindrical shape. The exterior member 12 is provided so as to cover, for example, a part of the outer periphery of the electric wire member 11 in the longitudinal direction.
[0030] The exterior member 12 is, for example, a corrugated tube having a bellows structure in which large diameter portions 31 and small diameter portions 32 having a diameter smaller than that of the large diameter portions 31 are alternately connected along its length. That is, the bellows structure allows the exterior member 12 to be easily bent. Examples of materials that can be used for the exterior member 12 include synthetic resins such as polyolefin, polyamide, polyester, and ABS resin.
[0031] The exterior member 12 has a slit 33 extending along the length direction in a part of the circumferential direction. The slit 33 is formed, for example, over the entire length of the exterior member 12. This allows the exterior member 12 to be attached to the electric wire member 11 from the outside of the electric wire member 11. In other words, the exterior member 12 can be attached to the electric wire member 11 later through the slit 33. For example, after a part of the electric wire member 11 has been processed, the exterior member 12 can be arranged so as to cover the outer periphery of the electric wire member 11 from the outside of the electric wire member 11.
[0032] (Holder 13) As shown in FIG. 1 , the holder 13 is attached to the mounting end 12a, which is one end in the longitudinal direction of the exterior member 12. The holder 13 is made of resin. Examples of materials that can be used for the holder 13 include synthetic resins such as polypropylene, polyamide, and polyacetal. The holder 13 prevents contact between the electric wire 21 and the mounting end 12a of the exterior member 12, for example. In other words, the holder 13 protects the electric wire 21.
[0033] As shown in FIGS. 1 and 3, the holder 13 includes, for example, an insertion portion 41, a flange portion 42, a fixing piece 43, and a ground wire holding portion 44. The insertion portion 41 is cylindrical. The insertion portion 41 is inserted into the interior of the exterior member 12 from the attachment end 12a along the longitudinal direction of the exterior member 12. The outer circumferential surface of the insertion portion 41 contacts the inner circumferential surface of the exterior member 12. When the exterior member 12 is a corrugated tube, the outer circumferential surface of the insertion portion 41 contacts the inner circumferential surface of the small diameter portion 32 of the exterior member 12.
[0034] The insertion portion 41 has a locking protrusion (not shown) that protrudes from the outer circumferential surface of the insertion portion 41. The locking protrusion hooks onto the inner circumferential surface of the exterior member 12 in the length direction of the exterior member 12. This prevents the insertion portion 41 from slipping out of the exterior member 12. If the exterior member 12 is a corrugated tube, the locking protrusion of the insertion portion 41 hooks onto, for example, a step between the small diameter portion 32 and the large diameter portion 31 on the inner circumferential surface of the exterior member 12. Each electric wire 21 is passed inside the insertion portion 41.
[0035] The flange portion 42 extends outward from the insertion portion 41. The insertion portion 41 has a first end 41a, which is one end of the insertion portion 41 in the axial direction, and a second end 41b, which is the end opposite the first end 41a in the axial direction. The flange portion 42 is provided at the first end 41a of the insertion portion 41. The flange portion 42 is formed, for example, in a ring shape that is continuous around the entire circumference of the insertion portion 41. The flange portion 42 faces the mounting end 12a of the exterior member 12 in the length direction of the exterior member 12. That is, the flange portion 42 is interposed between each electric wire 21 and the mounting end 12a. This prevents each electric wire 21 from interfering with the mounting end 12a.
[0036] (Earth wire holding part 44) The earth wire holding portion 44 is provided in, for example, the insertion portion 41 of the holder 13. The earth wire holding portion 44 is formed, for example, so as to radially penetrate a peripheral wall that forms the insertion portion 41. The earth wire holding portion 44 has, for example, a slit shape that extends from the second end 41b of the insertion portion 41 along the axial direction of the insertion portion 41. In other words, the earth wire holding portion 44 opens in the axial direction of the insertion portion 41 at the second end 41b of the insertion portion 41. The earth wire holding portion 44 clamps a portion of the earth wire 26 in the extending direction.
[0037] The ground wire 26 is passed from the inner periphery side to the outer periphery side of the insertion portion 41. The ground wire 26 is also passed through a slit 33 in the exterior member 12. That is, the ground wire 26 is drawn from the inner periphery side of the insertion portion 41 to the outer periphery side of the exterior member 12 through the ground wire holding portion 44 and the slit 33 in the exterior member 12. The slit 33 in the exterior member 12 may be closed, for example, by wrapping tape around it, in a portion of the exterior member 12 other than the portion where the holder 13 is attached.
[0038] (Fixed piece 43 and fastening member 51) The fixing pieces 43 of the holder 13 extend from the flange portion 42 along the longitudinal direction of the exterior member 12. The flange portion 42 is provided between the fixing pieces 43 and the insertion portion 41. The fixing pieces 43 are fastened and fixed together with the electric wires 21 by the fastening members 51. When viewed from the axial direction of the insertion portion 41, the fixing pieces 43 have, for example, an arc shape centered on the axis of the insertion portion 41. The fastening members 51 fasten each electric wire 21 to the fixing pieces 43 in a state in which each electric wire 21 contacts the inner surface of the fixing piece 43.
[0039] 1, the wire harness 10 includes fastening members 51 that fasten the holder 13 to the electric wires 21. The fastening members 51 are, for example, adhesive tape or cable ties. The fastening members 51 fasten the fixing pieces 43 of the holder 13 and the electric wires 21 together from the outer periphery. This fixes the electric wires 21 to the fixing pieces 43.
[0040] The operation of the first embodiment will be described. A holder 13 is provided at a position on the braided member 22 where the ground wire 26 is to be provided. The holder 13 is fixed to each electric wire 21 at a fixing piece 43, and is also attached to the mounting end 12a of the exterior member 12. The ground wire 26 is held by a ground wire holding portion 44 of the holder 13. Then, the ground terminal 14 attached to the ground wire 26 is fixed to the grounding member. As a result, the braided member 22 effectively suppresses noise radiation from the electric wire 21.
[0041] The effects of the first embodiment will be described. (1-1) The holder 13 fixed to the electric wire 21 has a ground wire holding portion 44 that holds a part of the ground wire 26 in the extending direction. According to this configuration, the ground wire holding portion 44 is provided on the holder 13 fixed to the electric wire 21, so the position of the ground wire 26 relative to the electric wire 21 can be stabilized. This stabilizes the impedance between the tubular portion 25 of the braided member 22 and the ground terminal 14 connected to the ground member. This stabilizes the shielding performance.
[0042] (1-2) The wire harness 10 includes a cylindrical exterior member 12 that covers the outer periphery of the electric wire member 11. The holder 13 having the ground wire holding portion 44 is attached to an attachment end 12a, which is one end in the longitudinal direction of the exterior member 12. This allows the ground wire 26 extending from the braided member 22 to be held near the end in the longitudinal direction of the exterior member 12.
[0043] (1-3) The holder 13 includes a cylindrical insertion portion 41 that is inserted inside the exterior member 12, and a flange portion 42 that extends radially outward from the insertion portion 41. The electric wire 21 is passed through the inside of the insertion portion 41. The flange portion 42 faces the mounting end portion 12a in the length direction of the exterior member 12. With this configuration, the flange portion 42 of the holder 13 can prevent the electric wire 21 from interfering with the mounting end portion 12a of the exterior member 12.
[0044] (1-4) The earth wire holding portion 44 is formed to penetrate radially through the insertion portion 41. The earth wire 26 is passed through from the inner periphery to the outer periphery of the insertion portion 41. This configuration allows the earth wire 26 to pass through the insertion portion 41 of the holder 13 to the outer periphery of the insertion portion 41.
[0045] (1-5) The exterior member 12 has a slit 33 through which the ground wire 26 passes. With this configuration, the ground wire 26 can be passed through the slit 33 of the exterior member 12 and out the outer periphery of the exterior member 12.
[0046] (1-6) The wire harness 10 includes a fastening member 51 that fastens the holder 13 to the electric wire 21. The holder 13 has a fixing piece 43 that is fastened and fixed together with the electric wire 21 by the fastening member 51. According to this configuration, the holder 13 is fixed to the electric wire 21 by the fastening member 51, and therefore the holder 13 and the earth wire 26 held in the earth wire holding portion 44 of the holder 13 can be held more stably.
[0047] (Second embodiment) Hereinafter, a second embodiment of the wire harness will be described. In this embodiment, differences from the first embodiment will be mainly described, and the same reference numerals will be used to designate the same or corresponding components as those in the first embodiment, and some or all of the description of the components will be omitted.
[0048] As shown in Fig. 4, the wire harness 10A of the second embodiment includes a cable tie 60 serving as a holder fixed to the electric wires 21. The cable tie 60 is made of, for example, a synthetic resin. The cable tie 60 bundles a plurality of electric wires 21. The cable tie 60 is configured to be attachable to the electric wires 21 from the outside of the electric wires 21.
[0049] The cable tie 60 has a band portion 61 that wraps around the outer circumference of the electric wire 21, and a locking portion 62 that is integrally formed at the base end of the band portion 61 in the longitudinal direction and into which the band portion 61 is inserted from the tip end and locked.
[0050] The band portion 61 is long and flexible, and has a plurality of protrusions (not shown) arranged in parallel in the longitudinal direction of the band portion 61. The locking portion 62 has a locking portion main body 62a and an extending portion 62b extending from the locking portion main body 62a in the longitudinal direction of the electric wire member 11. The band portion 61 is inserted into the locking portion main body 62a. The locking portion main body 62a is engaged with the convex portion of the band portion 61 so as to restrict movement of the band portion 61 in the removal direction, which is the opposite direction to the insertion direction, when the band portion 61 is passed through. The band portion 61 is inserted from its tip end into the locking portion main body 62a and engaged, thereby fastening the plurality of electric wires 21 together from the outer periphery. This bundles the plurality of electric wires 21.
[0051] The binding band 60 has a ground wire holding portion 63 that holds a portion of the ground wire 26 in the extending direction. The ground wire holding portion 63 is provided, for example, on the extending portion 62b of the locking portion 62. The extending portion 62b faces the tubular portion 25 of the braided member 22 in a direction perpendicular to the longitudinal direction of the electric wire member 11.
[0052] The ground wire holding portion 63 is formed to penetrate the extending portion 62b in a direction perpendicular to the longitudinal direction of the electric wire member 11. The ground wire holding portion 63 has, for example, a slit shape extending along the longitudinal direction of the electric wire member 11. The ground wire holding portion 63 is open in the longitudinal direction of the electric wire member 11 at the tip of the extending portion 62b in the longitudinal direction of the electric wire member 11. The ground wire holding portion 63 clamps a part of the ground wire 26 in the extending direction.
[0053] The effects of the second embodiment will be described. (2-1) The cable tie 60 fixed to the electric wire 21 has a ground wire holding portion 63 that holds a part of the ground wire 26 in the extending direction. With this configuration, the cable tie 60 fixed to the electric wire 21 is provided with the ground wire holding portion 63, so the position of the ground wire 26 relative to the electric wire 21 can be stabilized. This stabilizes the impedance between the tubular portion 25 of the braided member 22 and the ground terminal 14 connected to the ground member. This stabilizes the shielding performance.
[0054] (2-2) The binding band 60 has a band portion 61 that wraps around the outer periphery of the electric wires 21, and a locking portion 62 that is integrally formed at the base end of the band portion 61 in the longitudinal direction and into which the band portion 61 is inserted and locked from the tip end. The ground wire holding portion 63 is provided on the locking portion 62. With this configuration, the ground wire holding portion 63 provided on the binding band 60 that binds multiple electric wires 21 can stabilize the position of the ground wire 26 relative to the electric wires 21.
[0055] (Other embodiments) The above-described embodiments can be modified as follows: The above-described embodiments and the following modifications can be combined with each other within the scope of technical compatibility.
[0056] The configuration of the holder 13, such as its shape, is not limited to that of the first embodiment, but can be changed as appropriate depending on the configuration of the wire harness 10. 5, the earth wire holding portion 44 of the holder 13 may have a positioning portion 71 that is inserted into the slit 33 of the exterior member 12. The positioning portion 71 protrudes, for example, from each of a pair of clamping portions 44a that clamp the earth wire 26 in the earth wire holding portion 44 toward the outer periphery of the insertion portion 41. The earth wire holding portion 44 also clamps the earth wire 26 at the positioning portion 71, for example.
[0057] The positioning portion 71 is inserted into the slit 33 and thereby engages with the slit 33 in the circumferential direction of the exterior member 12. This determines the relative position of the exterior member 12 and the holder 13 in the circumferential direction of the exterior member 12. Therefore, it is possible to determine the position of the slit 33 in the circumferential direction relative to the wire member 11, i.e., the lead-out position of the earth wire 26.
[0058] In the first embodiment, the ground wire holding portion 44 of the holder 13 may be formed as a hole that radially penetrates the peripheral wall that forms the insertion portion 41. In other words, the ground wire holding portion 44 may have a shape that does not open in the axial direction of the insertion portion 41.
[0059] In the first embodiment, the earth wire holding portion 44 may be provided on a portion of the holder 13 other than the insertion portion 41, for example, on the flange portion 42. In the first embodiment, the flange portion 42 of the holder 13 may be provided partially in the circumferential direction of the insertion portion 41.
[0060] In the first embodiment, the exterior member 12 of the wire harness 10 may be, for example, a pipe-like member having a uniform diameter in the length direction, other than the corrugated tube. In the first embodiment, instead of the slits 33 in the exterior member 12, for example, through holes that penetrate the peripheral wall of the exterior member 12 in the radial direction may be provided. In this case, the ground wire 26 is drawn out to the outer periphery of the exterior member 12 through the through holes in the exterior member 12.
[0061] The wire harness 10A of the second embodiment may include an exterior member such as a corrugated tube that covers the outer periphery of the tubular portion 25 of the braided member 22, or may not include the exterior member.
[0062] The number of electric wires 21 is not limited to that in the above-described embodiments, and may be one or three or more. In the above embodiments, the ground terminal 14 is crimped to the ground wire 26, but this is not limiting. For example, the ground terminal 14 may be connected to the ground wire 26 by other means, such as welding or screwing.
[0063] Although not specifically mentioned in the above embodiments, the earth wire 26 may be insulated, for example, by wrapping insulating tape around its outer periphery. The embodiments and modifications disclosed herein are illustrative in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is defined by the claims, and it is intended to include all modifications within the meaning and scope of the claims. [Explanation of symbols]
