Description

[Technical Field]

[0001] The present invention relates to a shielding member for a wire harness, a wire harness with a shielding member, and a method for shielding a wire harness. [Background technology]

[0002] With the advancement of research and development into autonomous driving and the increasing popularity of electric vehicles, it is expected that the productivity and reliability of the electrical components installed in vehicles will increase in the future. For example, there are increasing demands for productivity and reliability for the shielding materials that shield wire harnesses from the electromagnetic waves emitted by each electrical component. In order for the shielding material to shield the wire harness from electromagnetic waves, the wire harness must be surrounded by a conductive shielding material, and the shielding material must also be earthed. Therefore, there is a demand for shielding materials that offer excellent productivity and workability.

[0003] Some shielding members for wire harnesses provide a shielding effect by covering electric wires with braided wire (see, for example, Patent Document 1). Other known shielding members use conductive nonwoven fabric (see Patent Documents 2 and 3). However, the shielding members described in these documents shield the entire wire harness even when shielding is required only in specific areas, resulting in poor productivity because they shield even areas that do not require shielding. Another problem is that if a wire harness without a shielding member is installed in a vehicle and shielding becomes necessary, the existing wire harness must be removed and replaced with a wire harness that does have a shielding member.

[0004] Therefore, a structure is known that improves productivity by surrounding a specific section of the electric wire to be shielded with a shielding metal thin film, and shielding the electric wire by connecting the drain wire in contact with the metal thin film to ground (Patent Document 4). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-174444 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-47354 [Patent Document 3] Japanese Patent Application Laid-Open No. 2015-115361 [Patent Document 4] Japanese Patent Application Laid-Open No. 2016-48713 Summary of the Invention [Problem to be solved by the invention]

[0006] However, to ground the shielding member using the structure described in Patent Document 4, it is necessary to connect the drain wire to the ground connection part of the vehicle body panel or the on-board equipment via a ground lead wire equipped with a circular ground terminal and an extension joint. Furthermore, to attach the shielding member to an existing wire harness using the structure described in Patent Document 4, it is necessary to remove the wire harness from the vehicle body and surround it with a thin metal shielding film. Therefore, there is a problem in that the workability of attaching and grounding the shielding member is not sufficiently improved.

[0007] The present invention has been made to solve such problems, and its object is to provide a shielding member for a wire harness, a wire harness with a shielding member, and a shielding method for a wire harness that can improve productivity and workability. [Means for solving the problem]

[0008] The shielding member for a wire harness of the present invention is provided so as to cover a portion of a wire harness routed on the surface of a conductive vehicle body that constitutes a vehicle, and comprises a conductive nonwoven fabric that is a metal-plated nonwoven fabric, and the conductive nonwoven fabric is attached to the vehicle body so as to cover a portion of the wire harness, thereby sandwiching the wire harness together with the vehicle body, and is grounded to the vehicle body at the attachment position.

[0009] Furthermore, the wire harness with a shielding member of the present invention comprises a wire harness routed on the surface of a conductive body that constitutes a vehicle, and a shielding member comprising a conductive nonwoven fabric that is a metal-plated nonwoven fabric and is provided so as to cover a portion of the wire harness, and the conductive nonwoven fabric is attached to the vehicle body so as to cover a portion of the wire harness, thereby sandwiching the wire harness together with the vehicle body, and is grounded to the vehicle body at the attachment position on the vehicle body.

[0010] The method for shielding a wire harness of the present invention includes a first step of covering a portion of a wire harness routed on the surface of a conductive vehicle body that constitutes a vehicle with a conductive nonwoven fabric that is a metal-plated nonwoven fabric, and sandwiching the portion of the wire harness between the vehicle body and the conductive nonwoven fabric, and a second step of attaching the conductive nonwoven fabric to the surface of the vehicle body and grounding it to the vehicle body at the attachment position on the vehicle body. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a shielding member for a wire harness, a wire harness with a shielding member, and a shielding method for a wire harness that can improve productivity and workability. [Brief explanation of the drawings]

[Figure 5] FIG. 4 is a second diagram for explaining the procedure of the method for shielding a wire harness using the shielding member according to the embodiment of the present invention.

[0013] The present invention will be described below in accordance with preferred embodiments. Note that the present invention is not limited to the embodiments shown below and can be modified as appropriate without departing from the spirit of the present invention. In addition, in the embodiments shown below, some components are omitted from illustration and description, but it goes without saying that publicly known or well-known technologies are applied as appropriate to the details of the omitted technologies within the scope of the content described below.

[0014] First, the configuration of a wire harness with a shielding member including a shielding member for a wire harness according to this embodiment will be described with reference to Figs. 1 to 3. Fig. 1 is a perspective view showing a wire harness with a shielding member including a shielding member according to this embodiment. Fig. 2 is a view of the wire harness with a shielding member of Fig. 1 as seen from the longitudinal direction of a vehicle body. Fig. 3 is a view showing details of the conductive nonwoven fabric of Fig. 1. The wire harness with a shielding member 1 shown in Figs. 1 and 2 is a harness used to connect electrical equipment (not shown) mounted on a vehicle 7, and includes a wire harness 3 and a shielding member 21 (shielding member for a wire harness).

[0015] The wire harness 3 shown in FIGS. 1 and 2 is an assembly of electric wires that transmit power and electric signals between electrical components mounted on a vehicle 7, and terminals and connectors (not shown) attached to the ends of the electric wires. The wire harness 3 is routed on the surface of a conductive vehicle body 9 that constitutes the vehicle 7. In FIG. 2, the wire harness 3 is illustrated as an electric wire including a core wire 3a, which is a metal wire that transmits power and electric signals, and an insulating layer 3b that covers the core wire 3a to prevent short circuits. However, the configuration of the wire harness 3 is not limited to that shown in FIG. 2. For example, the wire harness 3 may be formed by bundling multiple electric wires with adhesive tape or the like, or by covering the electric wires with an insulating tube such as a corrugated tube. On the other hand, the wire harness 3 in this embodiment is preferably an unshielded wire harness that does not include a shielding member. If the wire harness 3 includes a shielding member, the wire harness 3 can be shielded from electromagnetic waves without using the wire harness 1 with a shielding member of the present invention. The vehicle body 9 is not particularly limited as long as it is a component that constitutes the vehicle 7 and is conductive. For example, a body shell made of steel plate can be used. 1 and 2 show an example in which an L-shaped plate is used as the structure of the vehicle body 9 at the position where the wire harness 3 is routed, but the structure of the vehicle body 9 at the portion where the wire harness 3 is routed is not limited to an L-shaped plate. Also, while an example in which the wire harness 3 is routed at a corner of the inner surface (the surface where the bending angle is acute) of the bent portion of the L-shaped plate is shown in FIGS. 1 and 2, the location where the wire harness 3 is routed is not particularly limited as long as it is on the surface of the vehicle body 9. Furthermore, the wire harness 3 may be fixed to the vehicle body 9 by a clamp or the like (not shown) as needed.

[0016] The shielding member 21 is a member that shields the wire harness 3 from electromagnetic waves and includes a conductive nonwoven fabric 5 and, if necessary, a fixing member 11. The conductive nonwoven fabric 5 shown in FIG. 3 is a conductive nonwoven fabric that has been metal-plated. The conductive nonwoven fabric 5 shown in FIG. 3 is a member that shields the wire harness 3 from electromagnetic waves when grounded to the vehicle body 9 and includes a nonwoven fabric 5a, a plated portion 5b (metal plating), and, if necessary, an adhesive layer 5c. The nonwoven fabric 5a is a sheet-like member in which fibers are intertwined without being woven, and has a predetermined thickness. As shown in FIG. 3(b), due to the manufacturing characteristics, the fibers of the nonwoven fabric 5a are formed as multiple layers in the thickness direction. The material of the fibers that make up the nonwoven fabric 5a is not particularly limited as long as it can be manufactured to a size that can cover the region Z (see FIG. 1), can be metal-plated, and does not easily deteriorate in the usage environment of the wire harness 1 with a shielding member. For example, examples of fiber materials include polyethylene terephthalate (PET), polypropylene (PP), nylon, acrylic, glass fiber, carbon fiber, aramid fiber, and polyarylate fiber.

[0017] The plating portion 5b is a conductive metal (metal plating) that coats the fibers F that make up the nonwoven fabric 5a. The plating portion 5b is not particularly limited as long as it can absorb electromagnetic waves while grounded and does not easily peel off from the nonwoven fabric 5a. For example, the plating material can be one or more metals or alloys selected from the group consisting of copper, silver, gold, nickel, chromium, tin, zinc, palladium, rhodium, ruthenium, antimony, bismuth, germanium, cadmium, cobalt, and indium. The plating portion 5b may be formed as a single layer on the fibers F that make up the nonwoven fabric 5a, or may be formed as multiple layers. Therefore, the plating portion 5b may be formed, for example, with copper (first layer) and tin (second layer) on the fibers F that make up the nonwoven fabric 5a.

[0018] The conductive nonwoven fabric 5 may be formed by forming plated portions 5b on the fibers F and then entangling the fibers F to form the nonwoven fabric 5a, or by forming the nonwoven fabric 5a and then forming the plated portions 5b. A specific plating method is chemical plating such as electroless plating. A more specific plating method involves first immersing the fibers F or nonwoven fabric 5a in a treatment tank filled with a supercritical fluid or subcritical fluid (e.g., supercritical carbon dioxide) containing an organometallic complex of a plating catalyst metal, such as palladium. Next, the treatment tank is decomposed by thermal reduction by reducing the pressure and heating, and the plating catalyst metal is precipitated on the surface of the fibers F or nonwoven fabric 5a. Finally, chemical plating such as electroless plating is performed using the plating catalyst metal as a catalyst to form plated portions 5b on the fibers F or nonwoven fabric 5a.

[0019] The adhesive layer 5c is a layer for attaching and fixing the conductive nonwoven fabric 5 to the vehicle body 9 at the attachment position 15 (see FIG. 2), and is provided as needed. The adhesive layer 5c is provided between the conductive nonwoven fabric 5 and the vehicle body 9 in a state in which the conductive nonwoven fabric 5 is fixed to the vehicle body 9. Therefore, the adhesive layer 5c needs to be conductive in order to ground the conductive nonwoven fabric 5 to the vehicle body 9. A specific example of the adhesive layer 5c is an adhesive made of a conductive filler, a resin binder, or the like.

[0020] As shown in FIGS. 1 and 2 , the conductive nonwoven fabric 5 is provided so as to cover a part of the wire harness 3, in this case, a region Z which is a partial region in the axial direction of the wire harness 3. More specifically, the conductive nonwoven fabric 5 is attached to a vehicle body 9 so as to cover the region Z of the wire harness 3, thereby sandwiching the wire harness 3 together with the vehicle body 9. Furthermore, as shown in FIG. 2 , the conductive nonwoven fabric 5 is grounded to the vehicle body 9 at an attachment position 15 of the vehicle body 9. In the vehicle 7, the potential of the vehicle body 9 can be considered to be the potential in a grounded state (ground potential). Therefore, when the conductive nonwoven fabric 5 is grounded to the vehicle body 9, the potential of the conductive nonwoven fabric 5 also becomes the ground potential. Therefore, for example, the conductive nonwoven fabric 5 absorbs electromagnetic waves emitted by electrical components provided around the wire harness 3, thereby preventing the electromagnetic waves emitted by the electrical components from reaching the core wires 3 a of the wire harness 3, and thus shielding the wire harness 3 from the electromagnetic waves. Note that region Z is a region where, for example, electromagnetic waves emitted by electrical components provided around the wire harness 3 have an intensity that affects the signals and power transmitted by the wire harness 3, and more specifically, is the vicinity of the electrical components that emit electromagnetic waves. However, the conductive nonwoven fabric 5 not only prevents the electromagnetic waves emitted by the electrical components from reaching the wire harness 3, but also absorbs the electromagnetic waves emitted by the wire harness 3, thereby preventing the electromagnetic waves emitted by the wire harness 3 from reaching surrounding electrical components.

[0021] The fixing member 11 is a member that fixes the conductive nonwoven fabric 5 to the vehicle body 9 at the attachment position 15 and is provided as needed. FIGS. 1 and 2 illustrate an example of an adhesive tape such as vinyl tape that fixes the conductive nonwoven fabric 5 to the vehicle body 9 so as to straddle and cover them from above at the attachment position 15. Note that the fixing member 11 is not essential when the conductive nonwoven fabric 5 can be directly fixed to the vehicle body 9, such as when an adhesive layer 5c is provided on the attachment surface of the conductive nonwoven fabric 5 to the vehicle body 9. However, even when the adhesive layer 5c is provided, an adhesive tape may be used as the fixing member 11 to more securely fix the conductive nonwoven fabric 5 to the vehicle body 9. Furthermore, the member that fixes the conductive nonwoven fabric 5 to the vehicle body 9 is not limited to the adhesive layer 5c or the adhesive tape, and may be a conductive adhesive. When an adhesive is used, an uncured adhesive may be applied to at least one of the conductive nonwoven fabric 5 and the vehicle body 9, and then the conductive nonwoven fabric 5 and the vehicle body 9 are joined via the adhesive, and the adhesive may then be cured. The adhesive material may be the same as that of the adhesive layer 5c.

[0022] Whether to use the adhesive layer 5c, the fixing member 11, or an adhesive as a member for fixing the conductive nonwoven fabric 5 to the vehicle body 9 can be selected appropriately in consideration of the advantages of each. For example, when the adhesive layer 5c is used, it is advantageous in that the adhesive layer 5c is integrated with the conductive nonwoven fabric 5, and therefore there is no need to prepare a separate member for fixing the conductive nonwoven fabric 5 to the vehicle body 9. On the other hand, when the fixing member 11 is used, it is advantageous in that the fixing member 11 does not need to be conductive, and therefore an insulator can be selected as the material. Furthermore, when an adhesive is used, it is advantageous in that the conductive nonwoven fabric 5 can be adhered to the vehicle body 9 even if the conductive nonwoven fabric 5 does not have the adhesive layer 5c.

[0023] Although not shown in Figure 2, it is preferable to prevent electromagnetic waves from entering from both ends of the conductive nonwoven fabric 5 in the axial direction of the wire harness 3 by sealing the gap between the conductive nonwoven fabric 5 and the wire harness 3 with an adhesive layer 5c or adhesive tape.

[0024] As described above, the wire harness 1 with a shielding member and the shielding member 21 of this embodiment include the conductive nonwoven fabric 5 that covers a portion of the wire harness 3. Therefore, productivity can be improved compared to when the entire wire harness 3 is covered with the conductive nonwoven fabric 5. Furthermore, in the wire harness 1 with a shielding member and the shielding member 21 of this embodiment, the conductive nonwoven fabric 5 is attached to the vehicle body 9, and the wire harness 3 is sandwiched between the conductive nonwoven fabric 5 and the vehicle body 9, and the conductive nonwoven fabric 5 is grounded to the vehicle body 9 at attachment position 15. In this manner, the shielding member 21 shields the wire harness 3 from electromagnetic waves. In this configuration, the conductive nonwoven fabric 5 is grounded to the vehicle body 9 at attachment position 15, so that the conductive nonwoven fabric 5 serves as both the shielding member and the grounding member. Therefore, the shielding member 21 can be grounded simply by attaching the conductive nonwoven fabric 5 to the vehicle body 9 without using a drain wire, terminal, joint, or the like for grounding the shielding member 21, thereby improving workability when attaching the shielding member 21 to the wire harness 3. Furthermore, the shielding member 21 of this embodiment can also shield an existing wire harness 3 by covering it with the conductive nonwoven fabric 5. That is, the shielding member 21 of this embodiment can retrofit a shielding function to an existing wire harness 3 without removing the existing wire harness 3 from the vehicle body 9. Therefore, when a shielding function is required for an existing wire harness 3, it is not necessary to remove the wire harness 3 to attach the shielding member 21 or to replace the existing wire harness 3 with a wire harness having a shielding function. Therefore, the shielding member 21 of this embodiment improves the workability when attaching a shield structure to the wire harness 3. Furthermore, the wire harness 1 with a shielding member and the shielding member 21 of this embodiment sandwich the wire harness 3 between the vehicle body 9 and the conductive nonwoven fabric 5, thereby shielding the wire harness 3 from electromagnetic waves by having the vehicle body 9 assume part of the shielding function. Therefore, it is not necessary to completely surround the outer periphery of the wire harness 3 with the conductive nonwoven fabric 5, and the workability when attaching the shielding member 21 to the wire harness 3 is improved. The above is the description of the configuration of the wire harness 1 with the shielding member provided with the shielding member 21 according to this embodiment.

[0025] Next, a shielding method for a wire harness 3 using the shielding member 21 according to this embodiment will be described with reference to Fig. 1 and Figs. 4 to 6. Figs. 4 and 5 are first and second diagrams illustrating the procedure of the shielding method for a wire harness 3 using the shielding member 21. Fig. 6 is a third diagram illustrating the procedure of the shielding method for a wire harness 3 using the shielding member 21, and is a view of the vehicle body 9, wire harness 3, and conductive nonwoven fabric 5 in Fig. 5 as viewed from the longitudinal direction of the vehicle body 9. First, as shown in Fig. 4, it is assumed that the wire harness 3 is routed on the surface of a conductive vehicle body 9 that constitutes a vehicle 7. It is assumed that a region Z of this wire harness 3 needs to be shielded from electromagnetic waves for reasons such as being affected by electromagnetic waves emitted from surrounding electrical components.

[0026] In this case, as shown in FIGS. 5 and 6 , first, a region Z that is a part of the wire harness 3 is covered with a conductive nonwoven fabric 5, and a part of the wire harness 3 is sandwiched between the vehicle body 9 and the conductive nonwoven fabric 5 (first step). Next, the conductive nonwoven fabric 5 is attached to the surface of the vehicle body 9 and grounded to the vehicle body 9 at an attachment position 15 on the vehicle body 9 (second step). In the second step, if the conductive nonwoven fabric 5 has an adhesive layer 5c, the adhesive layer 5c is attached to the surface of the vehicle body 9, thereby fixing the conductive nonwoven fabric 5 to the surface of the vehicle body 9. At this time, if necessary, the conductive nonwoven fabric 5 may be fixed to the vehicle body 9 at the attachment position 15 using a fixing member 11 as shown in FIG. 1 . If the conductive nonwoven fabric 5 does not have the adhesive layer 5c, the conductive nonwoven fabric 5 is fixed to the vehicle body 9 at the attachment position 15 using the fixing member 11, or the conductive nonwoven fabric 5 is fixed to the vehicle body 9 via an adhesive. Furthermore, in the second step, if the surface of the vehicle body 9 is coated with an insulator such as paint, the insulator is removed from the attachment position 15 before attaching the conductive nonwoven fabric 5 to the surface of the vehicle body 9. The first step and the second step may be performed simultaneously. This completes the description of the shielding method for the wire harness 3 using the shielding member 21 according to this embodiment.

[0027] As described above, in the shielding method for the wire harness 3 according to the present embodiment, a portion of the wire harness 3 is covered with the conductive nonwoven fabric 5. Therefore, productivity can be improved compared to when the entire wire harness 3 is covered with the conductive nonwoven fabric 5. Furthermore, in the shielding method for the wire harness 3 according to the present embodiment, the conductive nonwoven fabric 5 is attached to the vehicle body 9, and the wire harness 3 is sandwiched between the conductive nonwoven fabric 5 and the vehicle body 9, and the conductive nonwoven fabric 5 is grounded to the vehicle body 9 at attachment position 15. In this way, the shielding member 21 shields the wire harness 3 from electromagnetic waves. By grounding the conductive nonwoven fabric 5 to the vehicle body 9 at attachment position 15, the conductive nonwoven fabric 5 serves as both a shielding member and a grounding member. Therefore, the shielding member 21 can be grounded by simply attaching the conductive nonwoven fabric 5 to the vehicle body 9 without using a drain wire, a terminal, a joint, or the like for grounding the shielding member 21. This improves workability when attaching the shielding member 21 to the wire harness 3. Furthermore, in the shielding method for the wire harness 3 according to the present embodiment, the existing wire harness 3 can also be shielded by covering it with the conductive nonwoven fabric 5. That is, in the shielding method for the wire harness 3 according to the present embodiment, a shielding function can be retrofitted to the existing wire harness 3 without removing it from the vehicle body 9. Therefore, when a shielding function is required for the existing wire harness 3, it is not necessary to remove the wire harness 3 to attach a shielding member or to replace the existing wire harness 3 with a harness having a shielding function. Therefore, the shielding method for the wire harness 3 according to the present embodiment improves the workability when attaching a shielding structure to the wire harness 3. Furthermore, in the shielding method for the wire harness 3 according to the present embodiment, the wire harness 3 is sandwiched between the vehicle body 9 and the conductive nonwoven fabric 5, so that part of the shielding function is taken on by the vehicle body 9, thereby shielding the wire harness 3 from electromagnetic waves. Therefore, it is not necessary to completely surround the outer periphery of the wire harness 3 with the conductive nonwoven fabric 5, and the workability when attaching the shielding member 21 to the wire harness 3 is improved. The above is the description of the shielding method for the wire harness 3 using the shielding member 21 according to this embodiment.

[0028] Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and modifications may be made without departing from the spirit of the present invention, and other techniques may be appropriately combined to the extent possible. Furthermore, publicly known or well-known techniques may be combined to the extent possible.

[0029] For example, in the above embodiment, the adhesive layer 5c, the fixing member 11, and the adhesive are exemplified as means for fixing the conductive nonwoven fabric 5 to the vehicle body 9 at the attachment position 15, but clips or the like may also be used. [Explanation of symbols]
