[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.
[0010] The wiring components of this disclosure are as follows:
[0011] (1) A wiring member includes a base member and a plurality of linear transmission members arranged side by side on the base member. The plurality of linear transmission members includes at least one coated linear transmission member and a plurality of bare wires, and the coated linear transmission member is arranged between the plurality of bare wires.
[0012] (1) According to the wiring member of (1), since the wiring member includes bare wires, the member cost of the coating layer of the bare wires can be reduced as compared with the case of using coated wires instead of bare wires. Since the coated linear transmission member is arranged between the plurality of bare wires, the bare wires are prevented from being adjacent to each other, and an unintentional short circuit between the bare wires can be suppressed.
[0013] (2) In the wiring member of (1), the height of the coated linear transmission member from the placement surface of the base member may be higher than the height of the bare wire from the placement surface. Thereby, the coated linear transmission member between the bare wires can function as an insulating wall higher than the bare wires.
[0014] (3) In the wiring member of (2), the coated linear transmission member has a transmission line body and a coating layer covering the transmission line body, and in a direction perpendicular to the placement surface, the dimension of the transmission line body may be the same as or larger than the dimension of the bare wire. Thereby, the difference between the height of the coated linear transmission member from the placement surface of the base member and the height of the bare wire can be increased.
[0015] (4) In any one of the wiring members of (1) to (3), the at least one coated linear transmission member may include a first outer linear transmission member arranged outside one of the plurality of linear transmission members arranged in parallel on the base member and a second outer linear transmission member arranged outside the other. Thereby, the exposure of the bare wire to the side of the wiring member can be suppressed.
[0016] (5) In any one of the wiring members (1) to (4), in a plan view, it includes an intersection where the plurality of linear transmission members intersect with each other, and the intersection may include at least one of a group consisting of a first intersection where the bare wires intersect with each other, a second intersection where the bare wire and the coated linear transmission member intersect, and a third intersection where the coated linear transmission members intersect with each other. Thereby, compared with the case where no intersection is provided, the degree of freedom of the paths of the plurality of linear transmission members on the base member increases.
[0017] (6) In the wiring member of (5), the intersection may include the first intersection of the group. Thereby, compared with the case where the first intersection is not provided, the degree of freedom of the path of the bare wire on the base member increases.
[0018] (7) In the wiring member of (6), in the first intersection, an insulating sheet may be provided between the bare wires intersecting with each other. Thereby, the short - circuit between the bare wires at the first intersection can be suppressed by the insulating sheet.
[0019] (8) In the wiring member of (7), the insulating sheet may be partially provided in a region including the first intersection with respect to the base member. Thereby, the increase in the size of the insulating sheet can be suppressed.
[0020] (9) In the wiring member of (7) or (8), the insulating sheet may have higher insulation than the base member. Thereby, the insulating sheet can be made thinner than the base member, and an increase in the thickness of the wiring member can be suppressed.
[0021] In the wiring member of (10)(5), the intersection portion includes the first intersection portion and the second intersection portion from the group, and the first bare wire intersects the second bare wire and the first and second covered linear transmission members on both sides of the second bare wire, respectively, so that the first and second intersection portions are provided, and the height of the first and second covered linear transmission members from the arrangement surface of the base member is higher than the height of the second bare wire, and there may be a hollow space between the bare wires that intersect each other at the first intersection portion. This makes it possible to suppress short circuits between bare wires at the first intersection portion without providing an insulating sheet or the like.
[0022] In the wiring member of (11)(5), the intersection may include only the second intersection, only the third intersection, or only the second and third intersections from the group. This suppresses the provision of intersections between bare wires and makes it easier to suppress short circuits between bare wires.
[0023] In the wiring member of (12)(5), the intersection may include the first intersection, the second intersection, and the third intersection from the group. This increases the degree of freedom of the paths of the bare wire and the insulated linear transmission member on the base member.
[0024] (13) In any one of the wiring members of (1) to (12), a first wiring member and a second wiring member are stacked on top of each other, and each of the first wiring member and the second wiring member includes the base member and the plurality of linear transmission members, and the base member of the first wiring member may be in contact with at least one of the plurality of linear transmission members of the second wiring member. This makes it possible to use the base member of the first wiring member as a cover member for the plurality of linear transmission members of the second wiring member.
[0025] In the wiring member of (14)(13), the bare wire of the first wiring member and the bare wire of the second wiring member are provided with an intersection where they cross each other, and the base member of the first wiring member may be positioned between the bare wire of the first wiring member and the bare wire of the second wiring member at the intersection. This allows the base member to suppress short circuits between the bare wires at the intersection of the bare wires.
[0026] In the wiring member of (15), (13), or (14), the bare wire of the first wiring member and the insulated linear transmission member of the second wiring member may overlap with each other and extend in the same direction, and the insulated linear transmission member of the first wiring member and the bare wire of the second wiring member may also overlap with each other and extend in the same direction. This can suppress an increase in the thickness of the wiring member.
[0027] [Details of the embodiments of this disclosure] Specific examples of the wiring components of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to these examples, and all modifications are intended to be included in the meaning and scope equivalent to the claims, as indicated by the claims.
[0028] [Embodiment 1] The wiring member 10 according to Embodiment 1 will be described below. Figure 1 is a plan view showing the wiring member 10 according to Embodiment 1. Figure 2 is a cross-sectional view taken along the line II-II in Figure 1.
[0029] The wiring member 10 comprises a base member 20 and a plurality of linear transmission members 30. The base member 20 is formed in a flattened shape overall. The plurality of linear transmission members 30 are linear members that transmit electricity or light, etc. The plurality of linear transmission members 30 are arranged in a line on the base member 20. The wiring member 10 is maintained in a flattened shape by fixing the plurality of linear transmission members 30 to the base member 20.
[0030] The base member 20 is formed in a sheet shape. The base member 20 holds multiple linear transmission members 30 in an aligned state. Regarding the material constituting the base member 20, in this case, the base member 20 is formed of a resin material. The material constituting the base member 20 may be a material other than resin, such as metal or inorganic material.
[0031] The structure of the base member 20 may be a single-layer structure or a multi-layer structure of two or more layers. The structure of the layers in the base member 20 is not particularly limited. For example, the base member 20 may have a layer made of a sheet having a uniform solid cross-section (also called a non-foamed sheet or solid sheet). Alternatively, the base member 20 may have a layer made of a foamed sheet or the like. Alternatively, the base member 20 may have a layer made of a fibrous material sheet such as a knitted fabric, woven fabric, or nonwoven fabric.
[0032] The base member 20 may be made of a soft material. For example, the base member 20 may have flexibility that can follow the bending of the linear transmission member 30. The wiring member 10 may be bendable in the thickness direction (bending such that the folds are along the main surface of the base member 20).
[0033] Each of the multiple linear transmission members 30 includes at least one insulated linear transmission member 31 and a plurality of bare wires 36. The insulated linear transmission member 31 transmits electricity or light, etc. The bare wires 36 transmit electricity.
[0034] A bare wire 36 is a wire that does not have an insulating coating layer 33 covering the conductor. In the examples shown in Figures 1 and 2, the bare wire 36 is a stranded wire in which multiple strands 37 are twisted together. In the stranded wire, multiple strands 37 come together to form a single conductive path. The bare wire 36 may consist of only one strand 37.
[0035] The covered linear transmission member 31 has a transmission line body 32 and a covering layer 33 that covers the periphery of the transmission line body 32. The transmission line body 32 is the part that transmits electricity or light, etc. For example, in a covered electric wire 31, the conductor core wire corresponds to the transmission line body 32, and in an optical fiber, the core and cladding correspond to the transmission line body 32. Here, the covered linear transmission member 31 is a covered electric wire 31 having a conductor core wire 32 and an insulating covering layer 33 that covers the conductor core wire 32. In the example shown in Figure 2, the covered electric wire 31 is a general covered electric wire that does not have a shielding layer or the like around the insulating covering layer 33. The covered electric wire 31 may also be a shielded wire that has a shielding layer around the insulating covering layer 33. The covered linear transmission member 31 may also be an enameled wire, a nichrome wire (heating wire), or an optical fiber, etc.
[0036] The covered linear transmission member 31 is a single linear object with one transmission path. The covered linear transmission member 31 may also be a composite of multiple linear objects, each having a different transmission path (e.g., a twisted wire, a cable made by bundling multiple linear objects together and covering them with a sheath).
[0037] The linear transmission member 30 that transmits electricity may be various signal lines or various power lines. Part of the linear transmission member 30 that transmits electricity may be used as an antenna, coil, etc., that sends signals or power to or receives them from space.
[0038] A covered linear transmission member 31 is placed between multiple bare wires 36. The space between parallel bare wires 36 is designated as the placement space. The number of placement spaces is the number of parallel bare wires 36 minus 1. There may be one or more placement spaces. The covered linear transmission members 31 are placed in the placement spaces so that no bare wires 36 are adjacent to each other. If there are multiple placement spaces, a covered linear transmission member 31 is placed in each placement space. The number of covered linear transmission members 31 is equal to or greater than the number of placement spaces.
[0039] Here, only one insulated linear transmission member 31 is placed in one arrangement space. Bare wires 36 and insulated linear transmission members 31 are arranged alternately between one outer bare wire 36 and the other outer bare wire 36 along the parallel direction. This makes it possible to increase the ratio of bare wires 36 to multiple linear transmission members 30. Note that multiple insulated linear transmission members 31 may be placed in one arrangement space, and the insulated linear transmission members 31 may be adjacent to each other.
[0040] The covered linear transmission member 31 has a first outer linear transmission member 31L positioned on one outer side of a plurality of linear transmission members 30 arranged in parallel on the base member 20, and a second outer linear transmission member 31R positioned on the other outer side. Therefore, in this case, covered linear transmission members 31 are positioned on both sides of all parallel bare wires 36. The number of covered linear transmission members 31 is at least one greater than the number of bare wires 36, and at least two greater than the number of available spaces.
[0041] Here, the height of the covered linear transmission member 31 from the placement surface 23 of the base member 20 is higher than the height of the bare wire 36 from the placement surface 23. In the example shown in Figure 2, the covered linear transmission member 31 and the bare wire 36 are so-called round wires with a circular cross-section. Therefore, the height of the covered linear transmission member 31 and the bare wire 36 from the placement surface 23 is approximately the same as the thickness (diameter) of the covered linear transmission member 31 and the bare wire 36. The difference in height occurs because the covered linear transmission member 31 is thicker than the bare wire 36. It should be noted that there may be cases where the covered linear transmission member 31 or the bare wire 36 is not a round wire. For example, if the covered linear transmission member 31 is a so-called flat wire with a rectangular cross-section, and the long side is placed on the placement surface 23, the height of the covered linear transmission member 31 from the placement surface 23 will be approximately the same as the length of the short side of the flat wire.
[0042] Here, in the direction perpendicular to the placement surface 23, the dimensions of the transmission line body 32 are the same as or larger than the dimensions of the bare wire 36. In the example shown in Figure 2, since the insulated linear transmission member 31 and the bare wire 36 are round wires, the thickness of the transmission line body 32 is the same as or greater than the thickness of the bare wire 36, resulting in this dimensional difference in the direction perpendicular to the placement surface 23. As a result, the height of the insulated linear transmission member 31 from the placement surface 23 is higher than the height of the bare wire 36 from the placement surface 23 by the thickness of the insulation layer 33 or more.
[0043] The wiring member 10 may include wires designated as signal lines and wires designated as power lines. In the wiring member 10, all bare wires 36 may be signal lines. In the wiring member 10, all wires designated as signal lines may be bare wires 36. In the wiring member 10, some of the wires designated as signal lines may be bare wires 36 and other parts may be insulated wires 31. In the wiring member 10, all wires designated as power lines may be insulated wires 31.
[0044] The wiring member 10 may comprise a plurality of wires with different conductor sizes. In this disclosure, the smallest of the plurality of conductor sizes is referred to as the first conductor size, and the next smallest conductor size is referred to as the second conductor size. The bare wire 36 consists only of wires of the first conductor size, and wires of the second conductor size and larger conductor sizes may be insulated wires 31. All wires of the first conductor size may be bare wires 36. A portion of the wires of the first conductor size may be bare wires 36, and the other portion may be insulated wires 31.
[0045] Multiple linear transmission members 30 are members that connect parts to each other in a vehicle. For example, a connector 40 is provided at the end of each linear transmission member 30. The linear transmission member 30 is connected to the other part by connecting this connector 40 to a mating connector provided on the mating part. In other words, this wiring member 10 is used as a wiring member 10 that electrically (or optically) connects various parts to each other in a vehicle or the like. The connector 40 may be fixed to the base member 20. The ends of the linear transmission members 30 may extend outside the base member 20, and the connector 40 may be provided separately from the base member 20.
[0046] The connector 40 may include a terminal 41 and a connector housing 46. The terminal 41 has a first connection portion 42 that connects to a mating terminal in a mating connector and a second connection portion 43 that connects to a linear transmission member 30. The configuration of the first connection portion 42 can be set as appropriate, and for example, it may be a male terminal structure or a female terminal structure. The terminal 41 may include a terminal 41A for insulated wires 31 and a terminal 41B for bare wires 36, the shapes of which of the second connection portion 43 are different. In the terminal 41A for insulated wires 31, the second connection portion 43A has a wire barrel 44 that is crimped to the conductor core and an insulation barrel 45 that is crimped to the insulating coating layer 33. In the terminal 41B for bare wires 36, the second connection portion 43B has a wire barrel 44 but does not have an insulation barrel 45.
[0047] In the example shown in Figure 1, the insulated wire 31 and the bare wire 36 are connected to the same connector 40. The same insulated wire 31 and bare wire 36 may be connected to different connectors 40. In the example shown in Figure 1, the arrangement of the insulated wire 31 and bare wire 36 in the connector 40 is the same as the arrangement of the insulated wire 31 and bare wire 36 in the base member 20. The arrangement of the insulated wire 31 and bare wire 36 in the connector 40 is the same as the arrangement of the insulated wire 31 and bare wire 36 in the base member 20.
[0048] The paths of the multiple linear transmission members 30 are set according to the location of the component to which they are connected. By fixing the multiple linear transmission members 30 to the base member 20, the multiple linear transmission members 30 are kept in a state that follows the wiring path according to the location of the component to which they are connected. The multiple linear transmission members 30 may be fixed to the base member 20 in a manner in which branch lines branch off from a main line. It is sufficient that the wiring member 10 has a section in which the multiple linear transmission members 30 run parallel to each other.
[0049] The linear transmission member 30 only needs to be fixed to the base member 20, and the fixing structure of the linear transmission member 30 to the base member 20 is not particularly limited. For example, the linear transmission member 30 is fixed to the base member 20. Such fixing may be done by fixing at the contact point, fixing at the non-contact point, or a combination of both. Here, fixing at the contact point means that the parts where the linear transmission member 30 and the base member 20 come into contact are stuck together and fixed. Fixing at the non-contact point is a fixing method that is not fixed at the contact point, for example, by using sewing thread 51, a cover, adhesive tape, etc. to press the linear transmission member 30 toward the base member 20 or to sandwich the linear transmission member 30 and the base member 20 and maintain that state.
[0050] In the examples shown in Figures 1 and 2, the fixing portion 50 between the linear transmission member 30 and the base member 20 is shown in a state of non-contact fixing. In the examples shown in Figures 1 and 2, the linear transmission member 30 and the base member 20 are fixed by sewing thread 51. In other words, the fixing portion 50 is formed by sewing thread 51. The pitch of the sewing thread 51 can be set as appropriate. In the example shown in Figure 1, the pitch of the sewing thread 51 of the bare wire 36 and the pitch of the sewing thread 51 of the insulated wire 31 are the same. The pitch of the sewing thread 51 of the bare wire 36 and the pitch of the sewing thread 51 of the insulated wire 31 may be different from each other.
[0051] <First modified example of fixing the linear transmission member 30 and the base member 20> Figure 3 is a cross-sectional view showing a first modified example of how the linear transmission member 30 and the base member 20 are fixed together. In this modified example, the same reference numerals are used for components that have been described previously, and their descriptions are omitted. The same applies to the descriptions of each embodiment and each modified example below.
[0052] In the example shown in Figure 3, the fixing portion 50A between the linear transmission member 30 and the base member 20 is in a state of contact fixation. This contact fixation can be indirect, direct, or a combination of both in different regions. Indirect fixation means that the linear transmission member 30 and the base member 20 are indirectly attached and fixed via an adhesive, tack, double-sided adhesive tape, etc., provided between them. Direct fixation means that the linear transmission member 30 and the base member 20 are directly attached and fixed without the use of a separate adhesive. In direct fixation, for example, the resin contained in at least one of the linear transmission member 30 and the base member 20 may be melted to cause them to stick together and be fixed.
[0053] In forming the state of direct fixation of the contact area, the resin may be melted by heat, for example, or by a solvent. In other words, the state of direct fixation of the contact area may be a state of direct fixation of the contact area by heat, or a state of direct fixation of the contact area by a solvent. Preferably, the state of direct fixation of the contact area by heat is preferred.
[0054] The means used to form the state of direct contact fixation at the contact points are not particularly limited, and known means such as welding, fusion, and other welding methods can be used. For example, when forming the state of direct contact fixation at the contact points by heat through welding, various welding methods such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding can be employed. When the state of direct contact fixation at the contact points is formed by these means, the linear transmission member 30 and the base member 20 are in a state of direct contact fixation at the contact points by those means. Specifically, for example, when the state of direct contact fixation at the contact points is formed by ultrasonic welding, the linear transmission member 30 and the base member 20 are in a state of direct contact fixation at the contact points by ultrasonic welding. In the example shown in Figure 3, the linear transmission member 30 and the base member 20 are in a state of direct contact fixation at the contact points.
[0055] When the linear transmission member 30 and the base member 20 are in a state of direct contact fixation, the base member 20 may have a two-layer structure including a first layer 21 and a second layer 22. The first layer 21 is a fixing layer. The linear transmission member 30 is directly fixed to the contact layer. The fixing layer includes a resin material, preferably a thermoplastic resin material. The resin material of the fixing layer softens and is directly fixed to the fixing mating surface at the contact point. The type of such resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used. It is preferable that the coating layer 33 also has the same resin material as the fixing layer. One surface of the first layer 21 is used as one main surface of the base member 20.
[0056] The second layer 22 is an additional layer. The second layer 22 may be made of a different material or have a different structure than the fixed layer. The second layer 22 enhances the functions of the fixed layer or adds functions to the base member 20 that are not present in the fixed layer. The material constituting the second layer 22 may be a metal, an inorganic material, or the like, in addition to the material described for the fixed layer. One surface of the second layer 22 becomes the other main surface of the base member 20.
[0057] The first layer 21 and the second layer 22 are fixed together while the other surface of the first layer 21 and the other surface of the second layer 22 are in contact. The manner in which the first layer 21 and the second layer 22 are fixed together is not particularly limited, but it is preferable that they be fixed by direct fixing at the contact points or indirect fixing at the contact points. For example, if at least one of the first layer 21 and the second layer 22 is a sheet with voids on its surface, such as a fibrous sheet or a foamed sheet, then a resin material or adhesive can be filled into the voids and fixed together. This produces a so-called anchoring effect, firmly fixing the first layer 21 and the second layer 22 together.
[0058] Here, the first layer 21 is described as a solid sheet made of resin, and the second layer 22 is described as a fibrous sheet. Here, the first layer 21 and the second layer 22 are described as being directly fixed at the contact area. That is, the resin of the first layer 21 penetrates between the fibers of the second layer 22 while in a fluid state, and then hardens. As a result, the state in which the resin of the first layer 21 penetrates between the fibers of the second layer 22 is maintained, and the first layer 21 and the second layer 22 are firmly fixed together.
[0059] The first layer 21 and the second layer 22 may be formed to the same size (same planar shape). One of the first layer 21 and the second layer 22 may be formed to be larger than the other. The entire contact area of the first layer 21 and the second layer 22 may be fixed. Only a portion of the contact area of the first layer 21 and the second layer 22 may be fixed. For example, the base member 20 may be a soft member, such as the first layer 21 being a solid sheet made of a soft resin such as soft PVC, and the second layer 22 being a nonwoven fabric made of PET.
[0060] In the case of direct fixing of the contact points, it is preferable that the coating layer 33 of the coated linear transmission member 31 and the first layer 21 contain the same resin as their main component. This allows both the coating layer 33 of the coated linear transmission member 31 and the first layer 21 to soften and bond with the other's resin. Also, in the case of direct fixing of the contact points, the resin of the first layer 21 softens and bonds with the stranded wire. In the example shown in Figure 3, the bare wire 36 is not a stranded wire but consists of a single strand 37. The stranded wire may be fixed to the base member 20 at the contact points.
[0061] In the case of fixing the contact points, each of the multiple linear transmission members 30 may be fixed to the base member 20 in a continuous manner along its entire longitudinal direction. Each of the multiple linear transmission members 30 may be fixed to the base member 20 at multiple points spaced apart along its longitudinal direction. Multiple linear transmission members 30 may be fixed to the base member 20 at the same position along its longitudinal direction. Multiple linear transmission members 30 may be fixed to the base member 20 at different positions along its longitudinal direction. In a single linear transmission member 30, the spacing between multiple fixing points may be the same or different.
[0062] <Second modified example of fixing the linear transmission member 30 and the base member 20> Figure 4 is a cross-sectional view showing a second modified example of how the linear transmission member 30 and the base member 20 are fixed together.
[0063] In the example shown in Figure 4, the fixing method between the bare wire 36 and the base member 20 is different from the fixing method between the insulated linear transmission member 31 and the base member 20. The bare wire 36 is fitted with a fixing part 50 that is fixed at a non-contact point, while the insulated linear transmission member 31 is fitted with a fixing part 50A that is fixed at a contact point. The fixing part 50 of the bare wire 36 is fixed to the base member 20 with sewing thread 51, similar to the example shown in Figure 2. The fixing part 50A of the insulated linear transmission member 31 is directly fixed at the contact point to the base member 20, similar to the example shown in Figure 3. However, the combination of the fixing part of the insulated linear transmission member 31 and the fixing part of the bare wire 36 can be set as appropriate.
[0064] <Effects of Embodiment 1> As described above, the wiring member 10, by including bare wires 36, can reduce the material cost by eliminating the need for the coating layer 33 of the bare wires 36 compared to the case where insulated wires 31 are used instead of bare wires 36. Since insulated linear transmission members 31 are placed between multiple bare wires 36, the bare wires 36 are prevented from being adjacent to each other, thereby preventing unintended short circuits between the bare wires 36. In addition, because there is no coating layer on the bare wires 36, the width dimension (the distance between the first outer linear transmission member 31L and the second outer linear transmission member 31R) when multiple linear transmission members 30 are lined up can be reduced compared to the case where insulated wires are used instead of bare wires 36. This allows the width dimension of the base member 20 to be reduced, thereby reducing the material cost.
[0065] Furthermore, the height of the covered linear transmission member 31 from the placement surface 23 is higher than the height of the bare wire 36 from the placement surface 23. As a result, the covered linear transmission member 31 between the bare wires 36 can function as an insulating wall that is higher than the bare wire 36. This makes it difficult for conductive dust or debris to come into contact with the bare wire 36 on the other side of the covered linear transmission member 31 when it straddles the covered linear transmission member 31 and the bare wire 36 on one side of the covered linear transmission member 31.
[0066] Furthermore, in the direction perpendicular to the placement surface 23, the dimensions of the transmission line body 32 of the covered linear transmission member 31 are the same as or larger than the dimensions of the bare wire 36. This allows for a large difference between the height of the covered linear transmission member 31 from the placement surface 23 and the height of the bare wire 36.
[0067] At least one covered linear transmission member 31 includes a first outer linear transmission member 31L positioned on one outer side of a plurality of linear transmission members 30 arranged in parallel on the base member 20, and a second outer linear transmission member 31R positioned on the other outer side. This prevents the bare wire 36 from being exposed on the side of the wiring member 10.
[0068] [Embodiment 2] A wiring member according to Embodiment 2 will now be described. Figure 5 is a plan view showing a wiring member 110 according to Embodiment 2. Figure 6 is a cross-sectional view along the line VI-VI in Figure 5.
[0069] The wiring member 110 has intersections where multiple linear transmission members 30 intersect each other in a plan view. In this disclosure, the intersection where bare wires 36 intersect each other is referred to as the first intersection 60. In this disclosure, the intersection where bare wires 36 intersect each other is referred to as the second intersection 61. The second intersection 61 may be a second intersection 61L where the bare wires 36 are located closer to the base member 20 (lower) than the covered linear transmission members 31, or a second intersection 61U where the covered linear transmission members 31 are located closer to the base member 20 (lower) than the bare wires 36. In the second intersection 61U, the bare wires 36 are located further away from the base member 20 (upper) than the covered wires 31. In this disclosure, the intersection where covered linear transmission members 31 intersect each other is referred to as the third intersection 62. The intersection in the wiring member 110 includes at least one of the group consisting of a first intersection 60, a second intersection 61, and a third intersection 62. In the example shown in Figure 5, the intersection includes the first intersection 60, the second intersection 61, and the third intersection 62.
[0070] In the example shown in Figure 5, bare wire 36A intersects with bare wire 36B and insulated wire 31B. Also, insulated wire 31A intersects with bare wire 36B and insulated wire 31B. The intersection of bare wire 36A and bare wire 36B is the first intersection 60. The intersection of bare wire 36A and insulated wire 31B is the second intersection 61U, and the intersection of insulated wire 31A and bare wire 36B is the second intersection 61L. The intersection of insulated wire 31A and insulated wire 31B is the third intersection 62.
[0071] As shown in Figure 6, bare wire 36A intersects with bare wire 36B and insulated wires 31B on both sides of bare wire 36B, respectively, forming a first intersection 60 and a second intersection 61U. The height of the insulated wires 31B from the placement surface 23 of the base member 20 is higher than the height of bare wire 36B. At the second intersections 61U adjacent to the first intersection 60, bare wire 36A is supported in contact with the insulated wires 31B. At the first intersection 60, bare wire 36A is supported above bare wire 36B with a gap between them. At the first intersection 60, the intersecting bare wires 36A and 36B do not touch each other. Also, there is a hollow space between bare wires 36A and 36B. Thus, even when bare wires 36A and 36B cross each other, if they can maintain a distance from each other sufficient to insulate them without touching, it is not necessary to provide an insulating sheet 70 or the like between the bare wires 36A and 36B.
[0072] In the example shown in Figure 5, the intersection is provided for the linear transmission members 30 to branch off from each other. Specifically, bare wire 36A and insulated wire 31A intersect with bare wire 36B and insulated wire 31B in order to branch off from bare wire 36B and insulated wire 31B. On one end of the intersection, bare wire 36A and insulated wire 31A run parallel to bare wire 36B and insulated wire 31B. On the other end of the intersection, bare wire 36A and insulated wire 31A extend in a different direction from bare wire 36B and insulated wire 31B. The intersection may also be provided to change the arrangement of the linear transmission members 30 in the parallel direction.
[0073] In this embodiment, the linear transmission member 30 is not folded back together with the base member 20 to form an intersection. At least one of the pair of linear transmission members 30 that constitute the intersection is not folded back together with the base member 20, but instead individually changes its path on the base member 20.
[0074] [First modified example of Embodiment 2] Figure 7 is a plan view showing a first modified example of the wiring member 110 according to Embodiment 2. Figure 8 is a cross-sectional view along the line VIII-VIII in Figure 7.
[0075] The wiring member 110A shown in Figure 7 includes an insulating sheet 70 placed between the bare wires 36 that intersect each other at the first intersection 60.
[0076] The insulating sheet 70 is partially provided on the base member 20 in the region including the first intersection 60. In the example shown in Figure 7, this region includes the second intersection 61 adjacent to the first intersection 60. This region also includes the second intersection 61U where the bare wire 36 forming the first intersection 60 intersects with the insulated wire 31B adjacent to the first intersection 60. This region also includes the second intersection 61L and the third intersection 62 where the insulated wire 31A, which runs parallel to the bare wire 36 forming the first intersection 60, intersects with the bare wire 36B and the insulated wire 31B. The region on which the insulating sheet 70 is provided may include only the first intersection 60, excluding the second intersection 61 and the third intersection 62. The region on which the insulating sheet 70 is provided may include only the first intersection 60 and the second intersection 61L, excluding the second intersection 61U and the third intersection 62. The area where the insulating sheet 70 is provided may not include the second intersection 61L and the third intersection 62, but may include only the first intersection 60 and the second intersection 61U.
[0077] The insulating sheet 70 may have higher insulating properties than the base member 20. For example, if the nonwoven fabric of the base member 20 is made of PET and the insulating sheet 70 is a nonwoven fabric mixed with aramid fibers or glass fibers, the insulating properties of the insulating sheet 70 can be made higher than those of the base member 20.
[0078] [Second modified example of Embodiment 2] Figure 9 is a plan view showing a second modified example of the wiring member 110 according to Embodiment 2. Figure 10 is a cross-sectional view along line XX in Figure 9.
[0079] The intersection may be configured so as not to include the first intersection 60. The intersection of the wiring member 110B according to the second modified example does not include the first intersection 60, but includes only the second intersection 61 and the third intersection 62. The intersection may not include the first intersection 60 and the third intersection 62, but include only the second intersection 61. The intersection may not include the first intersection 60 and the second intersection 61, but include only the third intersection 62.
[0080] <Effects of Embodiment 2 and its Modified Versions> The wiring members 110, 110A, and 110B according to Embodiment 2 and its modified form can also provide the same effects as the wiring member 10 according to Embodiment 1.
[0081] Furthermore, with wiring members 110, 110A, and 110B, since they have intersections where multiple linear transmission members 30 intersect each other in a plan view, the degree of freedom of the paths of the multiple linear transmission members 30 on the base member 20 is increased compared to cases where no intersections are provided.
[0082] Furthermore, according to the wiring members 110 and 110A, the intersection includes a first intersection 60. This increases the degree of freedom of the path of the bare wire 36 on the base member 20 compared to the case where the first intersection 60 is not provided.
[0083] Furthermore, according to the wiring members 110 and 110A, the intersection includes a first intersection 60, a second intersection 61, and a third intersection 62. This increases the degree of freedom in the paths of the bare wires 36 and the insulated linear transmission members 31 on the base member 20.
[0084] Furthermore, according to the wiring member 110, the height of the insulated wires 31B adjacent to the bare wire 36B from the placement surface 23 is higher than the height of the bare wire 36B from the placement surface 23, and at the first intersection 60, there is a hollow space between the bare wires 36A and 36B that intersect each other. As a result, short circuits between the bare wires 36A and 36B at the first intersection 60 can be suppressed without providing an insulating sheet 70 or the like.
[0085] Furthermore, according to the wiring component 110A, the insulating sheet 70 can suppress short circuits between the bare wires 36 at the first intersection 60.
[0086] Furthermore, according to the wiring member 110A, the insulating sheet 70 is partially provided in the region including the first intersection 60 with respect to the base member 20, thus preventing the insulating sheet 70 from becoming too large.
[0087] Furthermore, according to the wiring member 110A, the insulating sheet 70 has higher insulating properties than the base member 20, so the insulating sheet 70 can be made thinner than the base member 20, thereby suppressing an increase in the thickness of the wiring member 10.
[0088] Furthermore, the wiring component 110B helps to prevent intersections between bare wires 36, making it easier to prevent short circuits between bare wires 36.
[0089] [Embodiment 3] A wiring member according to Embodiment 3 will now be described. Figure 11 is a plan view showing a wiring member 210 according to Embodiment 3. Figure 12 is a cross-sectional view along the line XII-XII in Figure 11.
[0090] The wiring member 210 comprises a first wiring body 11 and a second wiring body 12 that are stacked on top of each other. Each of the first wiring body 11 and the second wiring body 12 includes a base member 20 and a plurality of linear transmission members 30. The base member 20 of the first wiring body 11 is in contact with at least one of the plurality of linear transmission members 30 of the second wiring body 12. In the stacked portion of the first wiring body 11 and the second wiring body 12, in the example shown in Figure 12, the insulated wires 31 overlap with each other, and the bare wires 36 overlap with each other. In the example shown in Figure 12, the base member 20 of the first wiring body 11 is in contact with the insulated wires 31 of the second wiring body 12. The base member 20 of the first wiring body 11 may have higher insulating properties than the base member 20 of the second wiring body 12. The nonwoven fabric of the base member 20 of the first wiring body 11 may be configured in the same way as the nonwoven fabric of the insulating sheet 70.
[0091] The first wiring body 11 and the second wiring body 12 are stacked in the portion that extends along the same path. In the example shown in Figure 11, the first wiring body 11 and the second wiring body 12 branch off midway, and the stacked state is resolved. The wiring member 210 is provided with a stacked extension portion in which the first wiring body 11 and the second wiring body 12 are stacked and extend along the same path, and an individual extension portion in which the first wiring body 11 and the second wiring body 12 extend individually without being stacked. The first wiring body 11 and the second wiring body 12 may remain stacked from one end to the other without branching midway. The wiring member 210 does not necessarily have an individual extension portion.
[0092] The wiring member 210 includes an intersection where the bare wires 36 of the first wiring body 11 and the bare wires 36 of the second wiring body 12 intersect. As shown in Figure 11, when the first wiring body 11 bends and branches off from a common path with the second wiring body 12, the bare wires 36 of the first wiring body 11 and the bare wires 36 of the second wiring body 12 intersect, forming a first intersection 60. At the first intersection 60, the base member 20 of the first wiring body 11 is located between the bare wires 36 of the first wiring body 11 and the bare wires 36 of the second wiring body 12.
[0093] [First modified example of Embodiment 3] Figure 13 is a cross-sectional view showing a first modified example of the wiring member 210 according to Embodiment 3.
[0094] In the wiring member 210A according to the first modified example, the bare wires 36 of the first wiring body 11 and the insulated linear transmission members 31 of the second wiring body 12 overlap each other and extend in the same direction, and the insulated linear transmission members 31 of the first wiring body 11 and the bare wires 36 of the second wiring body 12 overlap each other and extend in the same direction. In the example shown in Figure 13, the first wiring body 11 is deformed so that the insulated wires 31 of the first wiring body 11 fit into the space above the bare wires 36 of the second wiring body 12 and into the space between the insulated wires 31.
[0095] <Effects of Embodiment 3 and its Modified Versions> The wiring members 210 and 210A according to Embodiment 3 and its modified form can also obtain the same effects as the wiring member 10 according to Embodiment 1. In particular, because there is no coating layer on the bare wire 36, the width dimension (the distance between the first outer linear transmission member 31L and the second outer linear transmission member 31R) when multiple linear transmission members 30 are arranged side by side can be reduced compared to the case where coated wires are used instead of bare wires 36. As a result, the number of linear transmission members that can be arranged side by side on a single base member having a predetermined width dimension can be increased. As a result, it may be possible to reduce the number of layers in the laminated portion compared to the case where coated wires are used instead of bare wires 36, and thus the cost of the members can be reduced.
[0096] Furthermore, according to the wiring members 210 and 210A, the base member 20 of the first wiring body 11 can be used as a cover member for the multiple linear transmission members 30 of the second wiring body 12.
[0097] Furthermore, according to the wiring member 210, at the intersection where the bare wires 36 of the first wiring body 11 and the bare wires 36 of the second wiring body 12 intersect, the base member 20 of the first wiring body 11 is positioned between the bare wires 36 of the first wiring body 11 and the bare wires 36 of the second wiring body 12. As a result, at the intersection where the bare wires 36 intersect, the base member 20 can suppress short circuits between the bare wires 36.
[0098] Furthermore, with the wiring member 210A, since the insulated linear transmission member 31 and the bare wire 36 overlap between different wiring bodies, it is possible to suppress an increase in the thickness of the wiring member 10.
[0099] [Note] In the above wiring members 10, 110, 110A, and 110B, a cover member is not provided to cover the linear transmission member 30 from the side opposite to the base member 20. In the wiring members 10, 110, 110A, and 110B, a cover member may be provided to cover the linear transmission member 30 from the side opposite to the base member 20. The same applies to the first wiring body 11 in the laminated portion of the above wiring member 210. Such a cover member may be fixed to the base member 20, rather than being fixed to the linear transmission member 30. The cover member may be in contact with the linear transmission member 30, but not fixed.
[0100] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of Symbols]
