[Modes for carrying out the invention]

[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 comprising a plurality of wirings including a first wiring and a second wiring, and a plurality of sheaths covering at least some of the plurality of wirings, wherein the second wiring runs parallel to the first wiring in a first section and branches off from the first wiring at a first branching section, and the plurality of sheaths include a first sheath that covers the first wiring and the second wiring in the first section and a second sheath that covers the second wiring in a second section after the first branching section, and the first sheath and the second sheath are the same type of covering material formed from the same material.

[0012] According to the wiring component of (1), a portion of the long sheath, which includes the first and second sheaths, can be designated as the first sheath, and the other portion as the second sheath. This eliminates the need to provide another component such as a rubber hose in place of the sheath, thereby reducing costs.

[0013] (2) In the wiring member of (1), the plurality of wirings include a third wiring that runs parallel to the first wiring and the second wiring within the first sheath in the first section, and the second wiring and the third wiring run parallel to each other within the second sheath in the second section and may branch at a second branching section extending from the end of the second sheath. As a result, the second sheath functions as a protective material for the wiring between the first branching section and the second branching section.

[0014] (3) The wiring member of (1) or (2) may include a first resin molded part that covers the first wiring, the second wiring, the third wiring, the first sheath, and the second sheath at the first branching part, and a second resin molded part that covers the second wiring, the third wiring, and the second sheath at the second branching part. Since the materials of the first sheath and the second sheath are the same, it is easy to match the materials of the first resin molded part, the first sheath, and the second sheath with materials that are compatible with each other. Also, by making the material of the second resin molded part the same as the material of the first resin molded part, it is easy to match the materials of the second resin molded part and the second sheath with materials that are compatible with each other.

[0015] (4) In the wiring member of (3), the plurality of sheaths, the first resin molded portion, and the second resin molded portion may be formed of a urethane-based material. Thereby, the adhesiveness between the resin molded portion and the sheath is enhanced, and the water stoppage property between the resin molded portion and the sheath is enhanced.

[0016] (5) In the wiring member of (1), in the first branch portion, a resin molded portion covering the first wiring, the second wiring, the first sheath, and the second sheath may be provided. Thereby, since the materials of the first sheath and the second sheath are the same, it is easy to align the material of the first resin molded portion, the material of the first sheath, and the material of the second sheath with compatible materials.

[0017] (6) In the wiring member according to any one of (1) to (5), a trace of the first wiring removed may remain on the second sheath. Thereby, it becomes easy to determine that one original sheath was divided into the first sheath and the second sheath.

[0018] (7) Further, the manufacturing method of the wiring member of the present disclosure includes a step of preparing a cable including a plurality of wirings having a first wiring and a second wiring and a sheath covering the plurality of wirings, a step of cutting the sheath at an intermediate portion of the cable to divide it into a first sheath and a second sheath, and a step of removing the first wiring from the second sheath and branching it from the second wiring between the first sheath and the second sheath.

[0019] (7) According to the manufacturing method of the wiring member, a part of the sheath of the original cable can be used as the first sheath, and another part can be used as the second sheath. Thereby, it is not necessary to provide another member such as a rubber hose instead of the second sheath, and cost reduction can be achieved.

[0020] [Details of Embodiments of the Present 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.

[0021] [Embodiment 1] The wiring member 10 according to Embodiment 1 will be described below. Figure 1 is a perspective view showing the wiring member 10 according to Embodiment 1. Figure 2 is a plan view showing the wiring member 10 according to Embodiment 1. Figure 3 is an end view cut along the line III-III in Figure 1. Figure 4 is an end view cut along the line IV-IV in Figure 2. Figure 5 is an end view cut along the line VV in Figure 2.

[0022] The wiring component 10 comprises multiple wires and multiple sheaths. The wiring component 10 is placed, for example, in the undercarriage of a vehicle. The wiring component 10 connects the vehicle body equipment to the undercarriage equipment.

[0023] The multiple wirings include a first wiring 20 and a second wiring 30. Here, the multiple wirings also include a third wiring 40. The first wiring 20, the second wiring 30, and the third wiring 40 run parallel in the first section. The second wiring 30 and the third wiring 40 branch off from the first wiring 20 at the first branching point. The second wiring 30 and the third wiring 40 run parallel in the second section. The second wiring 30 and the third wiring 40 branch off at the second branching point.

[0024] Multiple sheaths cover at least some of the multiple wirings. The multiple sheaths include a first sheath 50 and a second sheath 54. The first sheath 50 covers the first wiring 20, the second wiring 30, and the third wiring 40 in the first section. The second sheath 54 covers the second wiring 30 and the third wiring 40 in the second section.

[0025] The first wiring 20 includes a plurality (in this case, a pair) of first insulated wires 21. Each first insulated wire 21 has a first core wire 22 and a first insulating sheath 23 covering the first core wire 22.

[0026] The second wiring 30 includes a plurality of second insulated wires 31 (in this case, a pair). Each second insulated wire 31 has a second core wire 32 and a second insulating sheath 33 covering the second core wire 32.

[0027] The third wiring 40 includes a plurality of third insulated wires 41 (in this case, a pair). Each third insulated wire 41 has a third core wire 42 and a third insulating sheath 43 covering the third core wire 42.

[0028] Each core wire 22, 32, and 42 is composed of one or more strands. The strands are made of a conductor such as copper, copper alloy, aluminum, or aluminum alloy. The strands may be twisted together.

[0029] Each insulating coating 23, 33, and 43 is formed by extruding resin around the core wires 22, 32, and 42. The type of resin is not particularly limited, but examples include polyvinyl chloride, polyolefin, or polyurethane.

[0030] The third wiring 40 includes a cable sheath 44 that covers a plurality of third insulated wires 41. The cable sheath 44 is formed by extruding resin onto the plurality of third insulated wires 41. The type of resin is not particularly limited, but examples include polyvinyl chloride, polyolefin, or polyurethane. With the cable sheath 44 provided, the third wiring 40 is considered to be a single cable. Hereinafter, the cable forming the third wiring 40 may be referred to as cable 40, using the same reference numeral as the third wiring 40.

[0031] The first wiring 20 and the second wiring 30 do not have cable sheath 44. Therefore, when the first sheath 50 is stripped, five wires are visible externally: two first insulated wires 21, two second insulated wires 31, and one cable 40.

[0032] The first insulated wire 21 is thinner than the second insulated wire 31. The third insulated wire 41 is the same thickness as the first insulated wire 21. Cable 40 is thicker than the first insulated wire 21. Cable 40 is thicker than the second insulated wire 31.

[0033] Two second insulated wires 31 and one cable 40 are arranged in a triangular shape in cross-section so as to be in contact with each other. One first insulated wire 21 is arranged so as to be in contact with one second insulated wire 31 and the cable 40. The other first insulated wire 21 is arranged so as to be in contact with the other second insulated wire 31 and the cable 40. The five wires are arranged in a pentagonal shape in cross-section.

[0034] Of the ends of the first insulated wire 21, the second insulated wire 31, and the cable 40, the end facing the first connector 11 is designated as one end, and the opposite end as the other end. In the first sheath 50, the end facing the first connector 11 is designated as one end 51, and the opposite end as the other end 52. In the second sheath 54, the end facing the first sheath 50 is designated as one end 55, and the opposite end as the other end 56.

[0035] The length from the other end of the first insulated wire 21 to the other end 52 of the first sheath 50 may be shorter than the length from the other end of the second insulated wire 31 to the other end 52 of the first sheath 50 and the length from the other end of the cable 40 to the other end 52 of the first sheath 50. The length from the other end of the first insulated wire 21 to the other end 52 of the first sheath 50 may be shorter than the length from the other end 56 of the second sheath 54 to the other end 52 of the first sheath 50. The length from the other end of the first insulated wire 21 to the other end 52 of the first sheath 50 may be shorter than the length from one end 55 of the second sheath 54 to the other end 56.

[0036] Here, the wiring member 10 includes intervening members 60 and 62. Intervening member 60 is interposed between the first sheath 50 and the plurality of wires. Intervening member 62 is interposed between the second sheath 54 and the plurality of wires. Intervening members 60 and 62 are, for example, sheet-like members that are vertically or spirally wound around the plurality of wires. Intervening members 60 and 62 are sometimes called retaining tape. Intervening members 60 and 62 may be, for example, nonwoven fabric, paper, or a solid sheet or foamed sheet made of resin.

[0037] Here, there is an empty space between the intervening members 60 and 62 and the wiring. The portion of the intervening member 60 that contacts the first insulated wire 21, the second insulated wire 31, and the cable 40 has a curved shape corresponding to the outer surfaces of the first insulated wire 21, the second insulated wire 31, and the cable 40, respectively. The portion of the intervening member 60 that does not contact the first insulated wire 21, the second insulated wire 31, and the cable 40 has a straight shape. The intervening member 60 is formed in a pentagonal shape when viewed in cross-section.

[0038] The wiring member 10 may include a second intervening member that fills the space between the intervening members 60 and 62 and the wiring. Such a second intervening member may be a fibrous member or the like that extending in the longitudinal direction of the wiring member 10. If the wiring member 10 includes the second intervening member, the intervening members 60 and 62 may have a shape that is close to a circle in cross-sectional view.

[0039] The first sheath 50 and the second sheath 54 are identical covering materials formed from the same material. The first sheath 50 and the second sheath 54 were originally a single sheath. The original sheath was cut in the middle and divided into the first sheath 50 and the second sheath 54. Identical covering materials are those that can be presumed to be the same covering material in this way. For example, the first sheath 50 and the second sheath 54 are formed by extruding resin around the first wiring 20, the second wiring 30, and the third wiring 40. The type of resin is not particularly limited, but examples include polyvinyl chloride, polyolefin, or polyurethane.

[0040] The second sheath 54 may have traces of the first wiring 20 being removed. For example, as shown in Figure 4, the intervening member 60 in the first sheath 50 has a pentagonal shape. As shown in Figure 5, the intervening member 62 in the second sheath 54 may also have a pentagonal shape. In this case, an unnatural empty space S remains inside the two corners 63 of the intervening member 62. That is, the two corners 63 of the intervening member 62 have an angular shape despite having an empty space S inside. Such corners 63 can be considered traces of the first wiring 20 being removed.

[0041] Multiple wires may be twisted together inside the sheath. For example, five wires, two first insulated wires 21, two second insulated wires 31, and one cable 40, may extend spirally along the extending direction of the wiring member 10 while maintaining a pentagonal arrangement. In this case, the two corners 63 may extend spirally along the extending direction of the second sheath 54.

[0042] Figure 6 is an end view showing a modified example of the traces left after removing the first wiring 20.

[0043] As shown in Figure 6, the second sheath 54 may have a force F that pushes the intervening member 62 and the multiple wires 30 and 40 radially inward. For example, during the extrusion molding of the sheath, the temperature of the sheath decreases from a flowable temperature to room temperature. This decrease in temperature can cause the sheath to contract, generating a force F. The second sheath 54 may be slightly compressed by the force F compared to the first sheath 50. Specifically, in the portion of the second insulated wire 31 and cable 40, the portion of the second insulated wire 31 and cable 40 resists the force F. On the other hand, there is no first insulated wire 21 inside the corner 63, and instead a space S exists. If the portion of the intervening member 62 and the second sheath 54 located outside the corner 63 cannot withstand the force F, the second sheath 54 may be compressed inward to fill the space S, as shown by the dashed line in Figure 6. At this time, the corner 63 of the intervening member 62 also deforms.

[0044] In this case, the curvature of the portion of the outer surface of the second sheath 54 located outside the corner 63 is different from the curvature of the portion located outside the second insulated wire 31 and the cable 40. The portion of the outer surface of the second sheath 54 located outside the corner 63 is a curvature change portion 57. Although a force F may also occur in the first sheath 50, the first sheath 50 can withstand the force F because of the presence of the first insulated wire 21.

[0045] Here, the wiring member 10 comprises a first resin molded part 70 and a second resin molded part 80. The first resin molded part 70 covers the first wiring 20, the second wiring 30, the third wiring 40, the first sheath 50, and the second sheath 54 at the first branching part. The second resin molded part 80 covers the second wiring 30, the third wiring 40, and the second sheath 54 at the second branching part.

[0046] The first resin molded section 70 holds the paths of the first section, the second section, and the first wiring 20 at the first branching section. The first resin molded section 70 has three extension outlets 71, 72, and 73. The first section extends from extension outlet 71, the second section extends from extension outlet 72, and the first wiring 20 extends from extension outlet 73. Here, the first sheath 50 extends from extension outlet 71, the second sheath 54 extends from extension outlet 72, and two first insulated wires 21 extend from extension outlet 73. Here, the path from the first branching section to extension outlet 73 is longer than the path from the first branching section to extension outlet 72.

[0047] Here, the first resin molded section 70 is formed in a T-shape. The first resin molded section 70 may be formed in a shape other than a T-shape. Here, the first resin molded section 70 is formed in a planar shape. Three paths connecting the three extension outlets 71, 72, and 73 from the first branching section are parallel to a single plane. The first resin molded section 70 may be formed in three dimensions.

[0048] A portion of the fixing piece B is also embedded in the first resin molded part 70. The fixing piece B is, for example, a bracket. One end of the bracket is fixed to the outer circumference of the other end 52 of the first sheath 50. The first resin molded part 70 also covers the one end of the bracket. The other end of the bracket extends out from the first resin molded part 70. A vehicle fixing part is provided at the other end of the bracket.

[0049] Here, the wiring member 10 includes a third resin molded portion 90. The third resin molded portion 90 is provided at one end 51 of the first sheath 50. Similar to the first resin molded portion 70, a part of the fixing piece B is embedded in the third resin molded portion 90. The fixing piece B is, for example, a bracket. One end of the bracket is fixed to the outer circumference of the first sheath 50. The first resin molded portion 70 also covers one end of the bracket. The other end of the bracket extends from the first resin molded portion 70. A vehicle fixing portion is provided at the other end of the bracket.

[0050] The second resin molded section 80 holds the paths of the second section, the second wiring 30, and the third wiring 40 at the second branching section. The second resin molded section 80 has three extension outlets 81, 82, and 83. The second section extends from extension outlet 81, the second wiring 30 extends from extension outlet 82, and the third wiring 40 extends from extension outlet 83. Here, the second sheath 54 extends from extension outlet 81, two second insulated wires 31 extend from extension outlet 82, and one cable 40 extends from extension outlet 83. Here, the path from the second branching section to extension outlet 82 is longer than the path from the second branching section to extension outlet 83.

[0051] Here, the second resin molded section 80 is formed in a T-shape. The second resin molded section 80 may be formed in a shape other than a T-shape. Here, the second resin molded section 80 is formed in a planar shape. The three paths connecting the three extension outlets 81, 82, and 83 from the second branching section are parallel to a single plane. The second resin molded section 80 may be formed in three dimensions.

[0052] Multiple sheaths, the first resin molded section 70, and the second resin molded section 80 are formed from a urethane-based material. This improves the adhesion between the first resin molded section 70, the first sheath 50, and the second sheath 54. It also improves the adhesion between the second resin molded section 80 and the second sheath 54.

[0053] Here, the wiring component 10 includes a first connector 11, a second connector 12, a third connector 13, and a sensor 14. One end of each of the first wire 20, second wire 30, and third wire 40 is connected to a common first connector 11. The other end of the first wire 20 is connected to the second connector 12. The other end of the second wire 30 is connected to the third connector 13. The other end of the third wire 40 is connected to the sensor 14. For example, the second connector 12 is connected to an ADS (Active Damper Suspension). The ADS changes the elastic force by means of hydraulics or pneumatics. The third connector 13 is connected to an EPB (Electric Parking Brake). The EPB prevents the wheels from rotating after the vehicle has stopped. The sensor 14 is, for example, an ABS (Anti-lock Brake System) sensor. The ABS sensor measures the rotational speed of the vehicle's wheels.

[0054] Here, the wiring member 10 includes a first connector cover 91, a second connector cover 92, and a third connector cover 93. The first connector cover 91 covers from the end of the first sheath 50 to the rear end of the first connector 11. The second connector cover 92 covers from the extension outlet 73 to the rear end of the second connector 12. The third connector cover 93 covers from the extension outlet 82 to the rear end of the third connector 13.

[0055] <Manufacturing method> The method for manufacturing the wiring member 10 will be explained with further reference to Figures 7 to 10. Figures 7 to 10 are plan views showing the manufacturing process of the wiring member 10. The method for manufacturing the wiring member 10 comprises a preparation step, a division step, and a branching step.

[0056] The preparation process, as shown in Figure 7, involves preparing a cable 16 that includes multiple wires and a sheath covering the multiple wires. For example, the cable 16 is cut to a predetermined length from a long base material. In the cable 16, the sheath 17 extends from one end to the other. The first wire 20, the second wire 30, and the third wire 40 extend inside the sheath 17 from one end to the other.

[0057] The splitting process involves cutting the sheath 17 in the middle of the cable 16 to divide it into a first sheath 50 and a second sheath 54. In Figure 7, arrows A1 to A4 indicate the points where the sheath 17 is cut. A portion of the sheath 17 is stripped off after cutting. Here, the sheath 17 is stripped off in the sections from arrow A1 to one end of the sheath 17 (the right end in Figure 7), between arrows A2 and A3, and from arrow A4 to the other end of the sheath 17 (the left end in Figure 7).

[0058] As shown in Figure 8, the sheath remains in the section between arrow A1 and arrow A2, becoming the first sheath 50. The sheath remains in the section between arrow A3 and arrow A4, becoming the second sheath 54. In Figure 8, the first wiring 20, the second wiring 30, and the third wiring 40 are exposed where the sheath 17 has been stripped.

[0059] The branching process involves removing the first wiring 20 from the second sheath 54 and branching the first wiring 20 into the second wiring 30 between the first sheath 50 and the second sheath 54, as shown in Figure 9. Here, two first insulated wires 21 are removed from the second sheath 54. At this time, the presence of intervening members 60 and 62 suppresses contact between the second sheath 54 and the first insulated wires 21. This makes it easier to remove the first insulated wires 21 from the second sheath 54. Also, the first insulated wire 21 is the smallest of the five wires inside the sheath. Therefore, compared to the second insulated wire 31 and the cable 40, the frictional force required when removing it is small, making it easier to remove.

[0060] In this configuration, the second sheath 54 does not have a slit along its entire length. The first insulated wire 21 is pulled out from the end of the second sheath 54 that is on the side of the first sheath 50. The second sheath 54 may have a slit along its entire length. If a slit is provided, it becomes easier to pull out the first insulated wire 21.

[0061] In Figure 8, the length of the first insulated wire 21 is the same as the length of the second insulated wire 31 and the length of the cable 40. If the required length of the first insulated wire 21 from the other end 52 of the first sheath 50 to the second connector 12 is shorter than the length of the second insulated wire 31 and the length of the cable 40, the first insulated wire 21 may be cut before being pulled out of the second sheath 54. This shortens the length of the first insulated wire 21 that needs to be pulled out of the second sheath 54. If the required length of the first insulated wire 21 from the other end 52 of the first sheath 50 to the second connector 12 is shorter than the length from the other end 52 of the first sheath 50 to the other end 56 of the second sheath 54, the cutting position of the first insulated wire 21 may be at the other end 56 of the second sheath 54.

[0062] In Figure 9, the first insulated wire 21 is branched from the second insulated wire 31 and the cable 40 between the first sheath 50 and the second sheath 54. In addition, the second insulated wire 31 and the cable 40 are branched from the other end 56 of the second sheath 54.

[0063] The manufacturing method for the wiring member 10 includes a terminal connection step, a molding step, and a cover step.

[0064] The terminal connection process involves connecting the ends of the first wire 20, the second wire 30, and the third wire 40. As shown in Figure 10, one end of the first wire 20, the second wire 30, and the third wire 40 are connected to the first connector 11. The other end of the first wire 20 is connected to the second connector 12. The other end of the second wire 30 is connected to the third connector 13. The end of the third wire 40 is connected to the sensor 14.

[0065] The molding process, as shown in Figure 10, involves forming the first resin molded section 70 and the second resin molded section 80. The third resin molded section 90 is also formed during this process.

[0066] In forming the first resin molded part 70, the portion from the other end 52 of the first sheath 50 to one end 55 of the second sheath 54 and the first insulated wire 21 extending from the other end 52 of the first sheath 50 are placed in the first mold. Then, a flowable resin is poured into the first mold. This forms the first resin molded part 70. Due to the heat of the flowable resin, parts of the first sheath 50 and the second sheath 54 melt and bond with the resin forming the first resin molded part 70. Here, since the first resin molded part 70, the first sheath 50 and the second sheath 54 are formed from a urethane-based material, the resin forming the first resin molded part 70 and the first sheath 50 and the second sheath 54 become one.

[0067] In forming the second resin molded part 80, the other end 56 of the second sheath 54 and the second insulated wire 31 and cable 40 extending from the other end 56 of the second sheath 54 are placed in the second mold. Then, a flowable resin is poured into the second mold. This forms the second resin molded part 80. Due to the heat of the flowable resin, a portion of the second sheath 54 melts and adheres to the resin forming the second resin molded part 80. Here, since the second resin molded part 80 and the second sheath 54 are formed from a urethane-based material, the resin forming the second resin molded part 80 and the second sheath 54 become one.

[0068] The covering process involves attaching the first connector cover 91, the second connector cover 92, and the third connector cover 93. The terminal connection process, the molding process, and the covering process can be performed in any order. For example, after the molding process, covers 91, 92, and 93 may be passed through the ends of the wiring 20, 30, and 40 and positioned on the resin molded parts 70, 80, and 90. After the terminal connection process, covers 91, 92, and 93 may be shifted and attached to the connectors 11, 12, and 13.

[0069] <Effects, etc.> With the wiring member 10 configured as described above, a portion of the long sheath, which includes the first sheath 50 and the second sheath 54, can be designated as the first sheath 50, and the other portion as the second sheath 54. This eliminates the need to provide another component, such as a rubber hose, in place of the sheath, thereby reducing costs.

[0070] Furthermore, the second wiring 30 and the third wiring 40 run parallel within the second sheath 54 in the second section and branch off at the second branching point extending from the end of the second sheath 54. As a result, the second sheath 54 functions as a protective material for the wiring between the first branching point and the second branching point.

[0071] Furthermore, the wiring member 10 comprises a first resin molded section 70 and a second resin molded section 80. Since the materials of the first sheath 50 and the second sheath 54 are the same, it is easy to select materials that are compatible with each other for the first resin molded section 70, the first sheath 50, and the second sheath 54. Also, by using the same material for the second resin molded section 80 as for the first resin molded section 70, it is easy to select materials that are compatible with each other for the second resin molded section 80 and the second sheath 54.

[0072] Furthermore, multiple sheaths, the first resin molded section 70, and the second resin molded section 80 are formed from a urethane-based material. This improves the adhesion between the resin molded section and the sheath, and enhances the watertightness between the resin molded section and the sheath.

[0073] The second sheath 54 shows traces of where the first wiring 20 was removed. This makes it easy to determine that the sheath of the original single cable 16 was divided into the first sheath 50 and the second sheath 54.

[0074] Furthermore, the manufacturing method for the wiring member 10 includes the steps of cutting the sheath in the middle of the cable 16 to divide it into a first sheath 50 and a second sheath 54, and removing the first wiring 20 from the second sheath 54 and branching it off from the second wiring 30 between the first sheath 50 and the second sheath 54. This makes it possible to use a portion of the original cable 16's sheath as the first sheath 50 and the other portion as the second sheath 54. This eliminates the need to provide another component such as a rubber hose in place of the second sheath 54, thereby reducing costs.

[0075] [Note] Although the resin molded sections 70 and 80 have been described as being provided, this is not an essential configuration. The resin molded sections 70 and 80 do not need to be provided. The shape of the branching section may be maintained by tape or a protector.

[0076] Up to this point, the wiring component 10 has been described as having 6 cores, but this is not a mandatory configuration. The wiring component 10 may have 8 cores or other configurations. The first wiring 20, the second wiring 30, or the third wiring 40 may each have 3 or more cores. Alternatively, the wiring component 10 may have a fourth wiring that branches off from the first wiring 20, the second wiring 30, and the third wiring 40. In this case, the branching position of the fourth wiring can be set as appropriate.

[0077] 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]
