[0001] This invention relates to wire harnesses. Background Technology
[0002] Conventionally, as disclosed in Patent Document 1, it is known to use wiring components that assemble cylindrical electromagnetic wave absorbing components on multiple wires covered by a braided shield. This wiring component has a positioning member that fixes the relative positions of the electromagnetic wave absorbing component and the braided shield. The positioning member of the wiring component is fixed to the vehicle body by a bracket. Existing technical documents Patent documents
[0003] Patent Document 1: Japanese Patent Application Publication No. 2015-198042 Summary of the Invention The problem that the invention aims to solve
[0004] In the case of Patent Document 1, the position fixing member secures the braided shielding from the outside, thereby fixing the relative positions of the electromagnetic wave absorbing component and the braided shielding. Therefore, when the bracket is fixed to the vehicle body, a load or stress is sometimes applied to the braided shielding from the position fixing member. In this case, if a load or stress is applied to the braided shielding from the position fixing member with the electromagnetic wave absorbing component as a base, the braided shielding may be damaged.
[0005] The purpose of this specification is to provide a wire harness that prevents damage to the braided parts at the wire section equipped with electromagnetic wave absorbing components. Solution for solving the problem
[0006] The wiring harness that solves the aforementioned problem comprises: an electric wire; a cylindrical first protective member for housing the electric wire; a cylindrical second protective member coaxially disposed with the first protective member to house the electric wire together with the first protective member; and an outer member fixed at both ends to the ends of the first protective member and the second protective member, respectively, and housing the electric wire inside. The electric wire has an electric wire body, an electromagnetic wave absorbing member assembled to the electric wire body, and a braid covering the outer periphery of the electric wire body and the electromagnetic wave absorbing member. The outer member is directly or indirectly fixed to the assembly destination in a state that allows the electric wire portion equipped with the electromagnetic wave absorbing member to be moved and housed. Invention Effects
[0007] This instruction helps to prevent damage to the braided parts of wires equipped with electromagnetic wave absorbing components. Attached Figure Description
[0008] Figure 1 This is a schematic diagram showing an assembly example of the wire harness in the first embodiment. Figure 2 It is a 3D diagram of the wire harness. Figure 3 This is a cross-sectional view of the wire harness. Figure 4 This is a cross-sectional view of the wire harness in the second embodiment. Figure 5 It is a three-dimensional diagram of the fixed component. Figure 6 This is a cross-sectional view of the wire harness according to the third embodiment. Detailed Implementation
[0009] First, the implementation methods described herein will be listed and explained. [1] The wire harness described herein includes: an electric wire; a cylindrical first protective member for housing the electric wire; a cylindrical second protective member disposed coaxially with the first protective member to house the electric wire together with the first protective member; and an outer member fixed at both ends to the ends of the first protective member and the second protective member, respectively, and housing the electric wire inside. The electric wire has an electric wire body, an electromagnetic wave absorbing member assembled to the electric wire body, and a braid covering the outer periphery of the electric wire body and the electromagnetic wave absorbing member. The outer member is directly or indirectly fixed to the assembly destination in a state in which the part of the electric wire to which the electromagnetic wave absorbing member is assembled can be moved to house it.
[0010] According to the structure of this example, the external component that allows the movable storage of the wire portion equipped with the electromagnetic wave absorbing component is directly or indirectly fixed to the assembly destination. Therefore, when the wire harness is fixed to the assembly destination, it is less likely to apply assembly loads or stresses to the braided parts located on the surface of the electromagnetic wave absorbing component. Thus, it is less likely to damage the braided parts at the wire portion equipped with the electromagnetic wave absorbing component.
[0011] [2] In [1] above, the outer component has an outer component protrusion for direct fixation to the assembly destination. According to this structure, since no other components are needed for fixing the wire harness to the assembly destination, it helps to simplify the assembly structure of the wire harness.
[0012] [3] In [1] above, the outer component has an outer component protrusion for fixing to the fixing component, and the fixing component has a fixing component protrusion and a recess, the fixing component protrusion for fixing to the assembly destination, and the recess for engaging with the outer component protrusion. According to this structure, the wire harness can be assembled to the assembly destination using conventionally used fixing components. Furthermore, it is not necessary to make significant changes to the shape or structure of the assembly destination fixed by the fixing component.
[0013] [4] In [3] above, the fixing member has a recess near its end in the main body portion that supports the base end of the protrusion of the fixing member, and a fixing portion is formed on the opposite side of the recess in the main body portion. The fixing portion fixes the end of the outer member to the end of one of the first protective member and the second protective member. According to this structure, the wire harness can be fixed to the assembly destination by using a so-called cantilever wire harness clamp. Therefore, it helps to simplify the assembly structure of the wire harness.
[0014] [5] In [1] above, the fixing member includes a first fixing member and a second fixing member, wherein the first fixing member fixes one end of the outer component to the end of the first protective component, and the second fixing member fixes the other end of the outer component to the end of the second protective component. According to this structure, a common wire harness clamp can be used as the fixing member. Therefore, it helps to simplify the assembly structure of the wire harness.
[0015] [6] In any of [1] to [5] above, the electromagnetic wave absorbing member is formed in a ring shape, and the wire body passes through a hole in the center of the electromagnetic wave absorbing member. According to this structure, since the electromagnetic wave absorbing member can be used to surround a predetermined part of the wire body from the circumference, electromagnetic wave leakage is less likely to occur.
[0016] [Details of the implementation methods described in this specification] (First Embodiment) The first embodiment of this description is described below with reference to the accompanying drawings. Furthermore, the invention is not limited to these illustrations, but is shown by way of the claims and is intended to encompass all variations within the meaning and scope of the claims. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Additionally, the dimensional ratios of the various parts sometimes differ from the actual values.
[0017] (Wire harness 1) like Figure 1 As shown, vehicle 2 includes a wiring harness 1 as part of its electrical wiring. The wiring harness 1 includes, for example, wires 5 and a cylindrical wire protection section 6. The wires 5 are electrically connected to a first electrical mounting member 3 and a second electrical mounting member 4 provided on vehicle 2, and the wire protection section 6 houses the wires 5. The wire protection section 6 is routed, for example, with a portion exposed from the vehicle floor surface to the outside. The wiring harness 1 is formed, for example, into a two-dimensional or three-dimensional path.
[0018] (First protective component 9, second protective component 10) like Figure 2As shown, the wire harness 1 includes a first protective member 9, a second protective member 10, and an outer component 11. In this example, the first protective member 9, the second protective member 10, and the outer component 11 constitute the wire protection section 6.
[0019] The first protective member 9 is formed as a cylindrical shape, specifically a generally cylindrical shape, that houses the wire 5 internally. The first protective member 9 is, for example, a corrugated pipe. The first protective member 9 is formed, for example, in a manner that surrounds the entire circumferential area of the wire 5. The first protective member 9 is formed along its length direction (…). Figure 2 The first protective member 9 is alternately arranged with convex and concave corrugations (in the X-axis direction). The material of the first protective member 9 can be either a conductive resin material or a non-conductive resin material. For example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin are used.
[0020] The second protective member 10 is coaxially arranged with the first protective member 9 to house the wire 5 together with the first protective member 9. In this example, the second protective member 10 uses the same component as the first protective member 9, specifically a corrugated pipe. Therefore, since the second protective member 10 uses the same component as the first protective member 9, its description is omitted. The first protective member 9 and the second protective member 10 are arranged at a predetermined interval.
[0021] (External component 11) The outer component 11 is fixed at both ends to the ends of the first protective component 9 and the second protective component 10, respectively, and the wire 5 is housed inside the outer component 11. The outer component 11 is provided in such a way that it is mounted on the ends of the first protective component 9 and the second protective component 10. The outer component 11 is formed into a generally cylindrical shape with openings at both ends. Specifically, the first protective component 9 is fitted into the opening 11a at one end of the outer component 11, and the second protective component 10 is fitted into the opening 11b at the other end. The outer component 11 is formed such that the central portion bulges outward radially by a predetermined amount compared to both ends.
[0022] The outer component 11 may be made of a relatively hard elastic material. The elastic material may be a rubber or elastomer, such as ethylene-propylene-diene rubber. Thus, the outer component 11 may be made of resin or rubber.
[0023] One end of the external component 11 is fixed to the first protective component 9 by the first fastener 12, and the other end is fixed to the second protective component 10 by the second fastener 13. The first fastener 12 and the second fastener 13 are, for example, binding straps made of resin or metal. In addition, the first fastener 12 and the second fastener 13 may also be tightening rings, tape components, etc.
[0024] The first fastener 12 and the second fastener 13 are assembled in such a way that they fasten each end of the outer component 11 from the outer periphery. Specifically, the first fastener 12 and the second fastener 13 are liquid-tightly fixed to the outer peripheral surface of the outer component 11. Therefore, water and the like can be prevented from seeping in through the gap between the first protective member 9 and the outer component 11 and the gap between the second protective member 10 and the outer component 11.
[0025] (Wire 5) like Figure 3 As shown, the wire 5 includes a wire body 15, an electromagnetic wave absorbing member 16 mounted on the wire body 15, and a braided member 17 covering the outer periphery of the wire body 15 and the electromagnetic wave absorbing member 16. The wire 5 is housed inside the first protective member 9, the second protective member 10, and the outer member 11. The wire 5 is, for example, a high-voltage wire that applies high voltage and high current.
[0026] The wire body 15 is, for example, a wire structure having a core wire surrounded by an insulating sheath. The core wire may be, for example, stranded wire, cylindrical conductor, tubular conductor, or combinations thereof. The core wire material may be, for example, copper-based, aluminum-based, or other metallic materials. The insulating sheath may be, for example, made of an insulating material such as synthetic resin. The insulating sheath material may be, for example, a synthetic resin whose main component is a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene.
[0027] The main body of the wire 15 can be one or multiple wires. The main body of the wire 15 can be an electromagnetic shielding structure or a non-electromagnetic shielding structure.
[0028] (Electromagnetic wave absorbing component 16) like Figure 3 As shown, the electromagnetic wave absorbing member 16 is disposed within the outer casing 11 of the wire body 15. The outer surface of the electromagnetic wave absorbing member 16 is covered by braid 17. The electromagnetic wave absorbing member 16 is formed as a cylinder with holes 18 through which the wire body 15 passes. The electromagnetic wave absorbing member 16 is, for example, formed as a generally cylindrical shape. The electromagnetic wave absorbing member 16 is disposed separately from the first protective member 9 and the second protective member 10. The electromagnetic wave absorbing member 16 absorbs, for example, a portion of the electromagnetic waves emitted from the wire body 15. The electromagnetic waves are, for example, electromagnetic noise.
[0029] The electromagnetic wave absorbing component 16 is, for example, a ring-shaped magnetic core. The magnetic core absorbs electromagnetic waves emitted from the wire body 15 and converts them into mechanical energy such as vibration or heat energy. As a result, the electromagnetic waves emitted from the wire body 15 are less likely to affect surrounding equipment.
[0030] A magnet core is, for example, a shaped body containing a soft magnetic material. Examples of soft magnetic materials include iron (Fe), ferroalloys, and ferrites. Examples of ferroalloys include Fe-silicon (Si) alloys and Fe-nickel (Ni) alloys. Magnet cores may use ferrite cores, amorphous cores, or permalloy cores. Ferrite cores may be composed of soft ferrites exhibiting soft magnetism. Examples of soft ferrites include ferrites containing nickel (Ni) and zinc (Zn) or ferrites containing manganese (Mn) and zinc (Zn). The material of the magnet core is appropriately selected, for example, according to the frequency band of electromagnetic noise that needs to be reduced.
[0031] (Knitted piece 17) like Figure 3 As shown, the braided component 17 is formed in a cylindrical shape to cover both the wire body 15 and the electromagnetic wave absorbing member 16. The braided component 17 extends, for example, along the length of the wire body 15. Figure 3 The wire body 15 is formed in such a way that it surrounds the main body of the wire (in the X-axis direction) for approximately its entire length. The braid 17 is formed, for example, such that the outer diameter of the portion covering the electromagnetic wave absorbing member 16 is larger than the outer diameter of the other portions. The wire body 15, which is equipped with the electromagnetic wave absorbing member 16 and the braid 17, is housed in an internal space 19 formed by the first protective member 9, the second protective member 10, and the outer member 11.
[0032] Examples of braided components 17 include braided components made of multiple metal wires, and braided components made by combining metal wires and resin wires. The metal wires may be made of copper-based or aluminum-based metals. The resin wires may be made of reinforcing fibers with excellent insulation and shear resistance, such as para-aramid fibers.
[0033] (Structure for fixing wire harness 1 to assembly destination 21) like Figure 2 and Figure 3 As shown, the outer casing 11 can movably store the wire portion equipped with the electromagnetic wave absorbing member 16 (hereinafter referred to as the absorbing portion 22). Corresponding to the portion equipped with the electromagnetic wave absorbing member 16, the absorbing portion 22 is formed with a larger diameter compared to other portions of the wire 5. Furthermore, the absorbing portion 22 refers to the portion of the wire 5 composed of the wire body 15, the electromagnetic wave absorbing member 16, and the braid 17.
[0034] The outer component 11 is directly or indirectly fixed to the assembly destination 21. In this example, the outer component 11 is directly fixed to the assembly destination 21. Specifically, the outer component 11 has an outer component protrusion 23 for direct fixing to the assembly destination 21. The head of the outer component protrusion 23 is, for example, formed with a generally trapezoidal cross-section. The outer component protrusion 23 engages with a recess 24 formed in the assembly destination 21. The recess 24 is, for example, a through hole. The assembly destination 21 is, for example, the vehicle body.
[0035] (The role of the implementation method) Next, the function of this embodiment will be explained. like Figure 3 As shown, the structure for fixing the wire harness 1 to the assembly destination 21 is a structure for fixing the outer component 11 to the assembly destination 21. The outer component 11 can movably house the wire 5 at the location where the electromagnetic wave absorbing component 16 is located. Thus, in this example, the portion of the wire 5 where the electromagnetic wave absorbing component 16 is located, i.e., the absorbing part 22, is not fixed relative to the outer component 11 and is allowed to move inside the outer component 11. Specifically, the absorbing part 22 is arranged with a predetermined gap between it and the inner peripheral surface of the outer component 11.
[0036] However, in the case of a structure where the absorbent portion 22 is fastened and fixed to the assembly destination 21 using a bracket or the like, the load generated during the fixing operation when the bracket is fixed to the assembly destination 21 is applied to the braided part 17 of the absorbent portion 22, potentially causing damage to the braided part 17. On the other hand, in this example, the absorbent portion 22 is not tightly fixed to the outer component 11. Therefore, during the fixing operation of the wire harness 1 to the assembly destination 21, the load or stress generated by the outer component 11 is less likely to be applied to the braided part 17 of the absorbent portion 22. Therefore, the braided part 17 is less likely to be damaged.
[0037] (Effects of the implementation method) Based on the structure of the above-described embodiments, the following results can be obtained. (1-1) The wire harness 1 includes a wire 5, a cylindrical first protective member 9, a cylindrical second protective member 10, and an outer member 11. The first protective member 9 houses the wire 5. The second protective member 10 is coaxially arranged with the first protective member 9 to house the wire 5 together with the first protective member 9. The two ends of the outer member 11 are fixed to the ends of the first protective member 9 and the second protective member 10, respectively, and the wire 5 is housed inside the outer member 11. The wire 5 has a wire body 15, an electromagnetic wave absorbing member 16 assembled to the wire body 15, and a braided piece 17 covering the outer periphery of the wire body 15 and the electromagnetic wave absorbing member 16. The outer member 11 is directly fixed to the assembly destination 21 in a state that allows it to be moved to house the wire portion (absorbing part 22 in this example) equipped with the electromagnetic wave absorbing member 16.
[0038] According to the structure of this example, the outer component 11, which allows for the movable storage of the wire portion equipped with the electromagnetic wave absorbing member 16, is directly fixed to the assembly destination 21. Therefore, when the wire harness 1 is fixed to the assembly destination 21, it is less likely to apply assembly load or stress to the braided piece 17 located on the surface of the electromagnetic wave absorbing member 16. Thus, it is less likely to damage the braided piece 17 at the wire portion equipped with the electromagnetic wave absorbing member 16.
[0039] (1-2) The outer component 11 has an outer component protrusion 23 for direct fixation to the assembly destination 21. According to this structure, since no other components are needed for fixing the wire harness 1 to the assembly destination 21, it helps to simplify the assembly structure of the wire harness 1.
[0040] (1-3) The electromagnetic wave absorbing member 16 is formed in a ring shape, and the wire body 15 passes through the hole 18 in the center of the electromagnetic wave absorbing member 16. According to this structure, since the electromagnetic wave absorbing member 16 can surround a predetermined part of the wire body 15 from the circumference, electromagnetic wave leakage is not easily generated.
[0041] (Second Implementation) Next, the second embodiment will be described. Furthermore, the second embodiment is an example of a structure in which the assembly structure of the wire harness 1 of the first embodiment is indirectly fixed using the fixing member 30. Therefore, the same reference numerals are used for parts that are the same as in the first embodiment, and descriptions are omitted; only the different parts are described in detail.
[0042] (Structure for fixing wire harness 1 to assembly destination 21) like Figure 4 As shown, the outer component 11 is indirectly fixed to the assembly destination 21 via the fixing member 30. Specifically, the outer component 11 has an outer component protrusion 31 for fixing to the fixing member 30. In addition, the outer component protrusion 31 may be the same as the outer component protrusion 23 in the first embodiment.
[0043] like Figure 5 As shown, the fixing member 30 has a fixing member protrusion 32 and a recess 33. The fixing member protrusion 32 is used to fix to the assembly destination 21, and the recess 33 is used to engage with the outer component protrusion 31. The head of the fixing member protrusion 32 is, for example, formed with a generally trapezoidal cross-section. The base end of the fixing member protrusion 32 is, for example, supported by the main body portion 34 of the fixing member 30. The main body portion 34 is, for example, formed in a plate shape, and the fixing member protrusion 32 is formed on its upper surface. The fixing member protrusion 32 is, for example, positioned near the center of the upper surface of the main body portion 34. The recess 33 is positioned near the end of the main body portion 34. The recess 33 is, for example, a through hole.
[0044] The fixing member 30 has a fixing part 35, which fixes the end of the outer member 11 to the first protective member 9. The fixing part 35 has, for example, a strap structure. The fixing part 35 is located on the opposite side of the recess 33 in the main body 34. Thus, the fixing member 30 may also have an eccentric clamping member with the fixing part 35 located near the end of the main body 34.
[0045] like Figure 4 As shown, one end of the outer component 11 is fixed to the first protective component 9 by the fixing part 35 of the fixing member 30. The other end of the outer component 11 is fixed to the second protective component 10, for example, by a predetermined fastener 36. In this example, the fastener 36 is preferably a cable tie. Thus, one end of the outer component 11 is fixed to the first protective component 9 by the fixing part 35 of the fixing member 30, and the other end is fixed to the second protective component 10 by the fastener 36.
[0046] (The role of the implementation method) like Figure 4 As shown, in this example, the outer casing 11, which allows the wire 5 to be movably housed at the location where the electromagnetic wave absorbing member 16 is located, is mounted to the fixing member 30, and the fixing member 30 is fixed to the assembly destination 21. Thus, in this example, the absorbing part 22 is not fixed to the outer casing 11, and therefore allows movement within the outer casing 11. Therefore, when assembling the wire harness 1 to the assembly destination 21, the assembly load or pressure is less likely to be applied to the braided part 17 of the absorbing part 22. Therefore, the braided part 17 is less likely to be damaged.
[0047] Furthermore, the wire harness 1 is fixed to the assembly destination 21 by a fixing member 30, rather than by an external mounting member 11. Therefore, as the fixing member 30, components not previously used, such as wire harness clamps, can be used, so there is no need to make major changes to the structure or shape of the assembly destination 21. In addition, because wire harness clamps with proven practical applications can be used, the wire harness 1 is less likely to detach from the assembly destination 21.
[0048] (Effects of the implementation method) In addition to the effects described in the first embodiment, the following effects can also be obtained based on the structure of the above embodiments.
[0049] (2-1) The outer component 11 has an outer component protrusion 31, which is used to fix it to the fixing component 30. The fixing component 30 has a fixing component protrusion 32 and a recess 33. The fixing component protrusion 32 is used to fix it to the assembly destination 21, and the recess 33 is used to engage with the outer component protrusion 31. In this way, the outer component 11 is indirectly fixed to the assembly destination 21 via the fixing component 30 in a state that allows the wire portion (absorbing portion 22 in this example) on which the electromagnetic wave absorbing component 16 is mounted to be moved and stored. According to this structure, the wire harness 1 can be assembled to the assembly destination 21 by using the conventionally used fixing component 30. In addition, it is not necessary to make major changes to the shape or structure of the assembly destination 21 to which the fixing component 30 is fixed.
[0050] (2-2) The fixing member 30 has a recess 33 near its end in the main body 34 that supports the base end of the fixing member protrusion 32. A fixing part 35 is formed on the opposite side of the recess 33 in the main body 34. The fixing part 35 fixes the end of the outer member 11 to the end of one of the first protective member 9 and the second protective member 10 (in this example, the first protective member 9). With this structure, the wire harness 1 can be fixed to the assembly destination 21 by using a so-called cantilever wire harness clamp. Therefore, it helps to simplify the assembly structure of the wire harness 1.
[0051] (Third Implementation) Next, the third embodiment will be described. Furthermore, the third embodiment will only describe the parts that differ from the first and second embodiments.
[0052] (Structure for fixing wire harness 1 to assembly destination 21) like Figure 6 As shown, both ends of the outer component 11 are fixed to the first protective component 9 and the second protective component 10 by fixing members 40, which are separate from the outer component 11. Thus, the fixing member 40 in this example includes a first fixing member 41 and a second fixing member 42. The first fixing member 41 fixes one end of the outer component 11 to the end of the first protective component 9, and the second fixing member 42 fixes the other end of the outer component 11 to the end of the second protective component 10.
[0053] The first fixing member 41 and the second fixing member 42 are preferably, for example, wire harness clamps. In the case of a wire harness clamp, the first fixing member 41 has a strap portion 41a for fixing one end of the outer member 11 to the first protective member 9 and a protrusion 41b for fixing to the assembly destination 21. In the case of a wire harness clamp, the second fixing member 42 has a strap portion 42a for fixing the other end of the outer member 11 to the second protective member 10 and a protrusion 42b for fixing to the assembly destination 21.
[0054] (The role of the implementation method) like Figure 6 As shown, in this example, one end of the outer member 11 is fixed to the first protective member 9 using the first fixing member 41, and the other end of the outer member 11 is fixed to the second protective member 10 using the second fixing member 42. Furthermore, the wire harness 1 is assembled to the assembly destination 21 by fixing the first fixing member 41 and the second fixing member 42 to the assembly destination 21. Thus, in this example, the absorbent portion 22 is not fixed to the outer member 11, and therefore allows movement within the outer member 11. Therefore, when assembling the wire harness 1 to the assembly destination 21, the assembly load or pressure is less likely to be applied to the braided portion 17 of the absorbent portion 22. Therefore, the braided portion 17 is less likely to be damaged.
[0055] Furthermore, in this example, conventionally used components such as wire harness clamps can be used as the fixing member 40, so there is no need to make major changes to the shape or structure of the assembly destination 21. In addition, because a wire harness clamp with practical application results can be used, the wire harness 1 is less likely to fall off the assembly destination 21. Furthermore, a general-purpose wire harness clamp with a protruding part and a strap part can also be used as the fixing member 40.
[0056] (Effects of the implementation method) In addition to the effects described in the first and second embodiments, the following effects can also be obtained based on the structure of the above embodiments.
[0057] (3-1) The fixing member 40 includes a first fixing member 41 and a second fixing member 42. The first fixing member 41 fixes one end of the outer component 11 to the end of the first protective member 9, and the second fixing member 42 fixes the other end of the outer component 11 to the end of the second protective member 10. According to this structure, a common wire harness clamp can be used as the fixing member 40. Therefore, it helps to simplify the assembly structure of the wire harness 1.
[0058] (Other implementation methods) Furthermore, this embodiment can be implemented in the following variations. This embodiment and the following variations can be combined with each other within the scope of technical non-contradiction.
[0059] ■ In various embodiments, the electromagnetic wave absorbing member 16 is not limited to a ring shape formed throughout the entire circumference; for example, it may also be a shape formed on a portion of the circumference. ■ In various embodiments, the electromagnetic wave absorbing member 16 may be, for example, a structure in which a magnet core is assembled into a retainer.
