MODE FOR CARRYING OUT THE INVENTION

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring member of the present disclosure is as follows.

[0011] (1) It includes at least one first coated electric wire, at least one second coated electric wire, and at least a first sheet to which the first coated electric wire is fixed. A first hole is formed in the first sheet, and a connection portion where the core wire of the first coated electric wire and the core wire of the second coated electric wire are connected is located in a region where the first hole is formed. In the region where the first hole is formed, the first coated electric wire and the second coated electric wire can be connected. It becomes easy to connect the coated electric wires to each other at a certain position on the sheet.

[0012] (2) In the connection part, the core wires may be welded to each other. Thereby, in the connection part, parts for connecting the core wires to each other become unnecessary.

[0013] (3) The connection part may be provided in the middle part of the first covered electric wire. Thereby, an intermediate splice can be easily provided at a certain position of the sheet.

[0014] (4) The connection part may be provided at the end of the first covered electric wire. Thereby, the ends of the electric wires can be connected.

[0015] (5) At the end of the first covered electric wire, there is a covering layer on the tip side of the core wire, and the covering layer may be fixed to the first sheet. Thereby, it is easy to position the core wire at the end of the first covered electric wire at the position of the first hole.

[0016] (6) The core wire of the first covered electric wire and the core wire of the second covered electric wire may intersect. Thereby, it is easy to connect the core wires to each other.

[0017] (7) The second covered electric wire may be fixed to the first sheet. Thereby, electric wires fixed to the same sheet can be connected.

[0018] (8) It may further include a second sheet to which the second covered electric wire is fixed, a second hole is formed in the second sheet, and the first sheet and the second sheet may be laminated so that the first hole and the second hole overlap. Thereby, electric wires fixed to different sheets can be connected.

[0019] (9) The first sheet and the second sheet may extend in a direction intersecting each other from the position of the connection part. Thereby, a branch extending in a different direction is easily formed.

[0020] (10) A plurality of the connection parts may be provided, and the plurality of connection parts may be arranged in a stepped manner. Thereby, it is possible to suppress the crossing of the coating layer of the first coated wire and the coating layer of the second coated wire. Thereby, it is possible to suppress an increase in the thickness dimension of the wiring member.

[0021] (11) It further includes at least one linear transmission member, the linear transmission member is fixed to the first sheet, not connected to the first coated wire and the second coated wire, the second coated wire extends from the connection part to one side, and the linear transmission member may be arranged on the other side with respect to the connection part. Thereby, it is possible to suppress the linear transmission member from crossing the first coated wire and the second coated wire. Thereby, it is possible to suppress an increase in the thickness dimension of the wiring member.

[0022] (12) The first sheet and the second sheet may extend in the same direction from the position of the connection part. Thereby, it is possible to connect wires arranged in different layers among wires extending in the same direction.

[0023] (13) An insulating cover part covering the connection part may be provided. Thereby, it is possible to suppress a short circuit at the connection part.

[0024] (14) The insulating cover part may include a part formed by folding back a part of the first sheet. Thereby, the insulating cover part can be easily provided.

[0025] (15) A bending region part including a part that bends and extends along the first coated wire is provided on the first sheet, and the insulating cover part may be provided at a part that bends inward among the bending region parts. The bending region part is likely to have a poor sheet yield. By providing the insulating cover part at a part that bends inward among the bending region parts, it is possible to improve the sheet yield.

[0026] (16) A plurality of the first holes are formed in the first sheet, and the insulating cover portion may partition the connection portion at a position between the plurality of the first holes. Thereby, short-circuiting between the plurality of connection portions is suppressed.

[0027] [Details of Embodiments of the Present Disclosure] A specific example of the wiring member of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0028] [Embodiment 1] Hereinafter, the wiring member 10 according to Embodiment 1 will be described. FIG. 1 is a plan view showing the wiring member 10 according to Embodiment 1. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is an explanatory view showing a state of manufacturing the wiring member 10 according to Embodiment 1. Note that the cover 40 is omitted in FIG. 1.

[0029] The wiring member 10 includes a plurality of coated electric wires 20, a sheet 30, and a cover 40. The sheet 30 is formed in a flat shape as a whole. By fixing the plurality of coated electric wires 20 on the sheet 30, the wiring member 10 is kept in a flat form. What is obtained by fixing the coated electric wire 20 to the sheet 30 may be referred to as a wiring body 12. The cover 40 covers the coated electric wire 20 from the side opposite to the sheet 30.

[0030] The plurality of coated electric wires 20 are members for electrically connecting components in a vehicle. For example, a connector is provided at an end of the coated electric wire 20. By connecting this connector to a connector provided on the counterpart component, the coated electric wire 20 is connected to the counterpart component. That is, the present wiring member 10 is used as a wiring member 10 for electrically connecting various components in a vehicle or the like. The connector may be fixed to the sheet 30.

[0031] The routes of the plurality of coated electric wires 20 are set according to the positions of the components to be connected and the like. By fixing the plurality of coated electric wires 20 to the sheet 30, the plurality of coated electric wires 20 are kept in a state along the wiring routes according to the positions of the components to be their respective connection destinations and the like. The plurality of coated electric wires 20 may be fixed to the sheet 30 in a manner in which a branch line portion branches from a main line portion.

[0032] The coated electric wire 20 includes a core wire 22 and a coating layer 24. The core wire 22 has one or a plurality of strands. The strands are formed by linearly forming a conductor such as copper or aluminum. The coating layer 24 covers the periphery of the core wire 22. The coating layer 24 is an insulator such as resin. The coating layer 24 is formed, for example, by extruding a softened insulating material around the core wire 22.

[0033] The coated electric wire 20 may be various signal wires or various power lines. A part of the coated electric wire 20 or the like may be used as an antenna, a coil, etc. that sends or receives signals or power to / from space.

[0034] Six coated electric wires 20 are illustrated in FIG. 1. When it is necessary to distinguish the six coated electric wires 20, they may be referred to as coated electric wires 20a1 - 20a6.

[0035] The sheet 30 keeps the plurality of coated electric wires 20 arranged side by side. The plurality of coated electric wires 20 are fixed on the main surface of the sheet 30. The sheet 30 may be a resin sheet. For example, the sheet 30 may be formed of a resin such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. Also, the sheet 30 may be a non-woven fabric or a foam sheet, etc. Further, the sheet 30 may have a single-layer structure or a multi-layer structure. Also, the sheet 30 may have a metal layer. The sheet 30 is an example of the first sheet.

[0036] The covered electric wire 20 only needs to be fixed to the sheet 30, and the fixing mode of the covered electric wire 20 to the sheet 30 is not particularly limited. Such a fixing mode may be contact part fixing, non-contact part fixing, or both may be used in combination. Here, the contact part fixing means that the part where the covered electric wire 20 and the sheet 30 are in contact is adhered and fixed. Also, the non-contact part fixing is a fixing mode that is not contact part fixing. For example, a sewing thread, a cover, an adhesive tape, etc. press the covered electric wire 20 toward the sheet 30 or sandwich the covered electric wire 20 and the sheet 30 and maintain them in that state. Hereinafter, it will be described on the assumption that the covered electric wire 20 and the sheet 30 are in a state of contact part fixing.

[0037] As such a mode of contact part fixing, it may be indirect contact part fixing, direct contact part fixing, or both may be used in combination in different regions. Here, the indirect contact part fixing means that the covered electric wire 20 and the sheet 30 are indirectly adhered and fixed through an adhesive, an adhesive agent, a double-sided adhesive tape, etc. provided therebetween. Also, the direct contact part fixing means that the covered electric wire 20 and the sheet 30 are directly adhered and fixed without passing through an adhesive agent or the like provided separately. In the direct contact part fixing, for example, it is conceivable that the covered electric wire 20 and the sheet 30 are adhered and fixed by melting the resin contained in at least one of them.

[0038] When forming such a state of direct contact part fixing, it is also conceivable that the resin is melted by heat, for example, or melted by a solvent. That is, the state of direct contact part fixing may be a state of direct contact part fixing by heat or a state of direct contact part fixing by a solvent. Preferably, it is a state of direct contact part fixing by heat.

[0039] At this time, the means for forming the directly fixed state of the contact portion is not particularly limited, and known means such as welding, fusion bonding, and soldering can be used. For example, when forming the directly fixed state of the contact portion by heat through welding, various welding means such as ultrasonic welding, heat-pressure welding, hot air welding, and high-frequency welding can be adopted. Further, when the directly fixed state of the contact portion is formed by these means, the covered wire 20 and the sheet 30 are in the directly fixed state of the contact portion by that means. Specifically, for example, when the directly fixed state of the contact portion is formed by ultrasonic welding, the covered wire 20 and the sheet 30 are in the directly fixed state of the contact portion by ultrasonic welding.

[0040] Hereinafter, the covered wire 20 and the sheet 30 will be described as being in the directly fixed state of the contact portion.

[0041] Each covered wire 20 may be fixed at a plurality of positions spaced apart along the longitudinal direction from the sheet 30. Each covered wire 20 may be continuously fixed to the sheet 30 along the longitudinal direction as a whole. Here, since the covering layer 24 in the covered wire 20 and the sheet 30 are directly fixed at the contact portion, the portion of the covered wire 20 fixed to the sheet 30 is the portion where the covering layer 24 is provided.

[0042] Holes 32 are formed in the sheet 30. The holes 32 are formed at positions offset laterally from the path along which the covered wire 20 extends straight in the sheet 30. In the portion of the sheet 30 where the holes 32 are formed, the width dimension is partially larger compared to the portion where the holes 32 are not formed. Further, a plurality of holes 32 are concentrated and arranged at one location. Thereby, it is easy for the plurality of holes 32 to be covered by one insulating cover portion. Of course, the holes 32 may be on the path along which the covered wire 20 extends straight. Also, a plurality of holes 32 may be dispersedly arranged. Four holes 32 are shown in FIG. 1. When it is necessary to distinguish the four holes 32, they may be referred to as holes 32a1 - 32a4.

[0043] The connection part 26 is located in the region where the hole 32 is formed. The connection part 26 is a part where the core wires 22 in the plurality of covered electric wires 20 are electrically connected. In FIG. 1, two connection parts 26 are shown. When it is necessary to distinguish between the two connection parts 26, they may be referred to as connection parts 26a1 and 26a2.

[0044] In the connection part 26a1, the covered electric wires 20a1, 20a2, and 20a3 are connected. The covered electric wires 20a1, 20a2, and 20a3 are connected in the middle part. Here, when the covered electric wire 20 is connected in the middle part, it means a case where both ends of the covered electric wire 20 are connected to different connection destinations respectively. In the middle part of each of the covered electric wires 20a1, 20a2, and 20a3, the core wire 22 is exposed by being stripped or the like. And these exposed core wires 22 are connected to form the connection part 26. The connection part 26a1 is located in the region where the hole 32a1 is formed.

[0045] That the connection part 26 is located in the region where the hole 32 is formed means that in a plan view, the connection part 26 is located at the position of the hole 32, and also means that in a plan view, the connection part 26 is located at the periphery of the hole 32. At a position close to the exposed core wire 22, the covering layer 24 is fixed to the periphery of the hole 32 in the sheet 30. The exposed core wire 22 including the connection part 26 is not fixed to the sheet 30 and can move. For this reason, the connection part 26 may be located at a position slightly deviated from the hole 32 in a plan view. Note that the connection part 26 may be located inside the hole 32 or outside the hole 32 in the thickness direction of the sheet 30.

[0046] In the connection part 26a2, the covered electric wires 20a4 and 20a5 are connected. The covered electric wires 20a4 and 20a5 are connected in the middle part. In the middle part of each of the covered electric wires 20a4 and 20a5, the core wire 22 is exposed by being stripped or the like. And these exposed core wires 22 are connected to form the connection part 26a2. The connection part 26a2 is located in the region where the hole 32a3 is formed.

[0047] At each connection part 26, the core wires 22 of the plurality of covered electric wires 20 cross each other. Here, the core wires 22 cross each other because the plurality of covered electric wires 20 cross the hole 32 while changing the arrangement. Hereinafter, an example of the connection part 26a1 will be described.

[0048] In the example shown in FIG. 1, regarding the connection part 26a1, on the left side of the hole 32a1, the covered electric wires 20a1, 20a2, 20a3 are arranged in this order from top to bottom. On the right side of the hole 32a1, the covered electric wires 20a1, 20a2, 20a3 are arranged in the order of the covered electric wires 20a3, 20a2, 20a1 from top to bottom. As a result, the directions in which the respective covered electric wires 20a1, 20a2, 20a3 cross the hole 32a1 can be different, and the core wires 22 of the covered electric wires 20a1, 20a2, 20a3 can cross at the position of the hole 32a1. The covered electric wires 20a3, 20a2, 20a1 return to the order of the covered electric wires 20a1, 20a2, 20a3 from top to bottom in the portion beyond the right side of the hole 32a1. For this reason, the covered electric wires 20a1, 20a2, 20a3 cross each other at a part of the covering layer 24 in order to return the arrangement order. However, the covered electric wires 20a3, 20a2, 20a1 may extend in this order from top to bottom in the portion beyond the right side of the hole 32a1.

[0049] The core wires 22 are welded to each other at each connection part 26. Thereby, the core wires 22 are maintained in a connected state. Such a welding method is not particularly limited, and various welding methods such as ultrasonic welding, resistance welding, and laser welding can be adopted. Further, the connection mode between the core wires 22 is not limited to welding, and various connection modes can be adopted. For example, the core wires 22 may be connected by crimping terminals to the core wires 22.

[0050] In the connection part 26, the core wires 22 are connected to each other as follows, for example. An example of the connection part 26a2 will be described. First, the coated electric wires 20a4 and 20a5 are wired and fixed on the sheet 30 along a predetermined path. At this time, the predetermined path includes a path that crosses the hole 32a3. That is, the coated electric wires 20a4 and 20a5 are arranged so as to cross the hole 32a3. The portions of the coated electric wires 20a4 and 20a5 that cross the hole 32a3 are not fixed to the sheet 30. The peripheral portions of the hole 32a3 of the coated electric wires 20a4 and 20a5 are fixed to the sheet 30. Also, the portions of each of the coated electric wires 20a4 and 20a5 that cross the hole 32a3 are stripped. As a result, the core wires 22 are exposed at the portions of each of the coated electric wires 20a4 and 20a5 that cross the hole 32a3. Also, the exposed core wires 22 are positioned so as to cross the hole 32a3. In this state, a connecting jig is applied to the core wires 22 of the coated electric wires 20a4 and 20a5, and the core wires 22 of the coated electric wires 20a4 and 20a5 are connected.

[0051] Such a jig varies depending on the connection method. For example, when the connection method is ultrasonic welding, the jig is the horn and anvil of an ultrasonic welder. Also, for example, when the connection method is a terminal, the jig is the crimper and anvil of a terminal crimping machine. Since the core wire 22 is located at the position of the hole 32, at the position of the hole 32, these jigs can sandwich the core wire 22 from both sides in the thickness direction of the sheet 30.

[0052] In FIG. 1, the region where the core wire 22 of the coated electric wire 20 is exposed is larger than the hole 32. That is, the core wire 22 is also exposed at the portion of the coated electric wire 20 that is located at the periphery of the hole 32. The region where the core wire 22 of the coated electric wire 20 is exposed may be the same as or smaller than the hole 32.

[0053] One of the coated electric wires 20a1, 20a2, and 20a3 is the first coated electric wire, and another one is the second coated electric wire. Similarly, one of the coated electric wires 20a4 and 20a5 is the first coated electric wire, and another one is the second coated electric wire. At least one first coated electric wire may be included. At least one second coated electric wire may be included.

[0054] There are holes 32a2 and 32a4 where the connecting portion 26 is not located. However, the holes 32a2 and 32a4 where the connecting portion 26 is not located may not exist. The connecting portion 26 may be located in all the holes 32.

[0055] The coated electric wire 20a6 is not connected to the coated electric wires 20a1, 20a2, 20a3, 20a4, and 20a5 at a certain position of the sheet 30. The coated electric wire 20a6 is an example of a linear transmission member that is not connected to the first coated electric wire and the second coated electric wire at a position where the sheet 30 is located. The linear transmission member may be, in addition to the above-mentioned coated electric wire 20, a bare wire, a shielded wire, a twisted wire, an enameled wire, a nichrome wire, a coaxial wire, an optical fiber, or the like. The linear transmission member may be a linear member that transmits electricity, light, or the like. The linear transmission member may be a single linear object or a composite of a plurality of linear objects (such as a twisted wire, a cable formed by aggregating a plurality of linear objects and covering this with a sheath). At least one linear transmission member may be included.

[0056] The cover 40 may be entirely overlapped with the sheet 30 or partially overlapped with it. The cover 40 may be a resin sheet. For example, the cover 40 may be formed of a resin such as PVC, PE, PP, or PET, similar to the sheet 30. One of the sheet 30 and the cover 40 may be softer than the other. Here, the softness, or conversely, the hardness may be evaluated by, for example, Rockwell hardness. For example, the cover 40 may be formed of a material such as rigid PVC, nylon, PET, or PP, and may be a soft member in which a sheet-like member formed of soft PVC and a non-woven fabric formed of PET are laminated.

[0057] The wiring member 10 is provided with an insulating cover portion that covers the connection portion 26. The insulating cover portion includes a portion formed by folding back a part of the sheet 30. In this example, the cover 40 covers the side of the sheet 30 where the covered electric wire 20 is disposed. The folded piece 34 of the sheet 30 covers the side of the sheet 30 where the covered electric wire 20 is not disposed. Therefore, the insulating cover portion includes the cover 40 and the folded piece 34 of the sheet 30.

[0058] The folded piece 34 is folded along the fold line L. The portion of the sheet 30 to which the covered electric wire 20 is fixed may be referred to as an electric wire fixing portion. Here, the folded piece 34 is provided adjacent to the portion of the sheet 30 where the hole 32 is formed along the width direction. The folded piece 34 may be provided adjacent to the portion of the sheet 30 where the hole 32 is formed along the longitudinal direction. Also, two folded pieces 34 may be provided, and the two folded pieces 34 may cover the portion of the sheet 30 where the hole 32 is formed from both sides.

[0059] The fixing manner of the sheet 30 and the cover 40 is not particularly limited, and the above various fixing manners of the sheet 30 and the covered electric wire 20 can be adopted. The fixing manner of the sheet 30 and the cover 40 may be the same as or different from the fixing manner of the sheet 30 and the covered electric wire 20.

[0060] The fixing manner of the electric wire fixing portion and the folded piece 34 is not particularly limited, and the above various fixing manners of the sheet 30 and the covered electric wire 20 can be adopted. The fixing manner of the electric wire fixing portion and the folded piece 34 may be the same as or different from the fixing manner of the sheet 30 and the covered electric wire 20, and the fixing manner of the sheet 30 and the cover 40.

[0061] According to the wiring member 10 configured as described above, the covered electric wires 20 can be connected in the region where the hole 32 is formed. It becomes easy to connect the covered electric wires 20 at a certain position of the sheet 30. Also, the covered electric wires 20 fixed to the same sheet 30 can be connected. Further, since the core wires 22 of the covered electric wires 20 intersect, it is easy to connect the core wires 22.

[0062] Also, since the core wires 22 are welded to each other at the connection part 26, parts for connecting the core wires 22 to each other are not required at the connection part 26. However, at the connection part 26, the core wires 22 may be connected to each other using separate parts such as terminals.

[0063] Since the connection part 26 is provided in the middle part of the covered electric wire 20, an intermediate splice can be easily provided at a certain position of the sheet 30. Note that one of the covered electric wires 20a1 - 20a3 may have its end connected at the connection part 26. Similarly, one of the covered electric wires 20a4, 20a5 may have its end connected at the connection part 26.

[0064] Also, since the insulating cover part is provided, a short circuit can be suppressed at the connection part 26. Also, since the insulating cover part includes a part formed by folding back a part of the sheet 30, the insulating cover part can be easily provided.

[0065] [Embodiment 2] The wiring member according to Embodiment 2 will be described. FIG. 4 is a plan view showing the wiring member 110 according to Embodiment 2. FIG. 5 is a cross-sectional view taken along the line V - V of FIG. 4. FIG. 6 is an explanatory view showing a state of manufacturing the wiring member 110 according to Embodiment 2. In the description of the present embodiment, the same reference numerals are given to the same components as those described so far, and the description thereof is omitted.

[0066] The wiring member 110 includes a plurality of wiring bodies 12b and 12c. The wiring body 12b includes a plurality of covered electric wires 20b1 - 20b12 and a sheet 30b. The wiring body 12c includes a plurality of covered electric wires 20c1 - 20c11 and a sheet 30c. A part of the plurality of wiring bodies 12b and 12c are laminated.

[0067] In the wiring body 12b, twelve coated electric wires 20b1 - 20b12 are shown. The twelve coated electric wires 20b1 - 20b12 are divided into three groups of the following coated electric wire groups G1, G2, and G3. That is, the coated electric wire group G1 is a group of coated electric wires 20 in which the core wire 22 is exposed in the middle part. One coated electric wire 20b1 belongs to the coated electric wire group G1. The coated electric wire group G2 is a group of coated electric wires 20 in which the core wire 22 is exposed at the end. Nine coated electric wires 20b2 - 20b10 belong to the coated electric wire group G2. The coated electric wires 20b2 - 20b7 and the coated electric wires 20b8 - 20b10 extend in opposite directions from the connection part 26. The coated electric wire group G3 is a group of coated electric wires 20 in which the core wire 22 is not exposed at a certain position of the sheet 30. It is possible that a connector to which the end of the coated electric wire group G3 is connected is arranged on the sheet 30. Two coated electric wires 20b11 and 20b12 belong to the coated electric wire group G3.

[0068] Holes 32b are formed in the sheet 30b. Eleven holes 32b are shown in FIG. 6. The eleven holes 32b are formed at positions corresponding to the exposed core wires 22 in the coated electric wires 20b1 - 20b10. Two holes 32b are formed at positions corresponding to the exposed core wire 22 in the coated electric wire 20b1.

[0069] In the wiring body 12c, eleven coated electric wires 20c1 - 20c11 are shown. All of the eleven coated electric wires 20c1 - 20c11 belong to the coated electric wire group G2. Holes 32c are formed in the sheet 30c. Eleven holes 32c are shown in FIG. 6. The eleven holes 32c are formed at positions corresponding to the exposed core wires 22 in the coated electric wires 20c1 - 20c11. The holes 32b and the holes 32c are arranged in the same sequence. Thereby, the sheets 30b and 30c can be laminated so that all of the corresponding holes 32b and 32c overlap each other.

[0070] The covered wire 20b1 is connected to covered wires 20c1 and 20c2. Covered wires 20c3 - 20c11 are respectively connected to covered wires 20b2 - 20b10. Each connection part 26 is provided at the end of the covered wire 20. The end of the covered wire 20 refers to the part where no connection destination is provided beyond it.

[0071] A plurality of connection parts 26 are arranged in a stepped manner. The connection part 26 between the covered wire 20b1 and the covered wires 20c1 and 20c2 is at the top. The connection parts 26 of the covered wires 20b2 - 20b7 and the covered wires 20c3 - 20c8 are arranged on the left side of the top. The connection parts 26 of the covered wires 20b2 - 20b7 and the covered wires 20c3 - 20c8 are separated from the top along the longitudinal direction of the sheet 30b as they are separated from the top along the width direction of the sheet 30b. Also, the connection parts 26 of the covered wires 20b8 - 20b10 and the covered wires 20c9 - 20c11 are arranged on the right side of the top. The connection parts 26 of the covered wires 20b8 - 20b10 and the covered wires 20c9 - 20c11 are separated from the top along the longitudinal direction of the sheet 30b as they are separated from the top along the width direction of the sheet 30b.

[0072] The number of connection parts 26 arranged on both sides of the top is different, but they may also be the same. Also, in the sheet 30b, the width dimensions of the parts extending on both sides of the top are different. That is, in the example shown in FIG. 4, since the number of connection parts 26 on the right side of the top is small, the width dimension of the part extending on the right side of the top in the sheet 30b is smaller than the width dimension of the part extending on the left side of the top. In the sheet 30b, the width dimensions of the parts extending on both sides of the top may also be the same.

[0073] Sheet 30b and sheet 30c extend from the position of the connection part 26 in directions intersecting each other. Thereby, it becomes easy to branch the wiring bodies 12b and 12c in different directions. Here, a hole 32b is formed in the middle part in the longitudinal direction of sheet 30b. A hole 32c is formed at the longitudinal end of sheet 30c. Sheet 30c extends in a direction (here, a direction perpendicular) intersecting the longitudinal direction of sheet 30b. Of course, in sheet 30b, the hole 32b may be formed at the position of the end of sheet 30b. In this case, a plurality of wiring bodies 12 are connected at the positions of the ends. Also, in sheet 30c, the hole 32c may be formed at the position of the middle part of sheet 30c. In this case, a plurality of wiring bodies 12 are connected at the positions of the middle parts.

[0074] All the coated electric wires 20c1 - 20c11 located at the end of sheet 30c are connected to the coated electric wires 20b1 - 20b10. Thereby, the connection part 26 between the wiring body 12b and the wiring body 12c can substitute for the part where so-called wire-to-wire connection is made using a connector.

[0075] The coated electric wires 20c1 - 20c11 extend from the connection part 26 to one side (the lower side in FIG. 4). The coated electric wires 20b11 and 20b12 are arranged on the other side (the upper side in FIG. 4) with respect to the connection part 26. That is, in the wiring body 12b, the coated electric wires 20b11 and 20b12 not used for connection with the wiring body 12c are arranged at positions shifted laterally when viewed from the longitudinal direction with respect to all the holes 32b used for connection with the wiring body 12c. Thereby, the coated electric wires 20b11 and 20b12 not used for connection with the wiring body 12c are suppressed from intersecting the coated electric wires 20c1 - 20c11.

[0076] The insulating cover portion partitions the connection portion 26 at a position between a plurality of holes 32 in one sheet 30. Here, as shown in FIG. 5, the cover 40 is joined to a portion between the holes 32 in the sheet 30c (joint portion A1). Also, the folded portion in the sheet 30b is joined to a portion between the holes 32 in the sheet 30b (joint portion A2). Further, here, a portion between the holes 32 in the sheet 30b and a portion between the holes 32 in the sheet 30c are joined (joint portion A3). From these, it is possible to suppress the direct contact and short circuit between the plurality of connection portions 26. Further, it is also possible to suppress the short circuit between the plurality of connection portions 26 via water or the like.

[0077] Also, with the wiring member 110 configured as described above, the coated electric wires 20 can be connected to each other in the region where the holes 32 are formed. It becomes easy to connect the coated electric wires 20 to each other at a certain position of the sheet 30.

[0078] Also, according to the wiring member 110, the coated electric wires 20 fixed to different sheets 30b and 30c can be connected to each other. Also, since the connection portion 26 is provided at the end of the coated electric wire 20, the ends of the electric wires can be connected. Also, since the sheet 30b and the sheet 30c extend in a direction intersecting each other from the position of the connection portion 26, a branch extending in a different direction is easily formed.

[0079] Also, since a plurality of connection portions 26 are provided and the plurality of connection portions 26 are arranged in a stepped manner, it is possible to suppress the intersection of the coated electric wires 20b1 - 20b10 and the coated electric wires 20c1 - 20c11 at the position of the coating layer 24. Thereby, it is possible to suppress an increase in the thickness dimension of the wiring member 110. However, the plurality of connection portions 26 do not necessarily have to be arranged in a stepped manner. Also, although the plurality of connection portions 26 are arranged in a stepped manner from the top to both sides, they may be arranged in a stepped manner only on one side from the top.

[0080] Since the covered electric wires 20c1-20c11 extend to one side from the connection part 26 and the covered electric wires 20b11, 20b12 are arranged on the other side with respect to the connection part 26, it is possible to suppress the covered electric wires 20b11, 20b12 from crossing the covered electric wires 20c1-20c11. Thereby, it is possible to suppress an increase in the thickness dimension of the wiring member 110.

[0081] Since the insulating cover part partitions the connection part 26 at positions between the plurality of holes 32, it is possible to suppress a short circuit between the plurality of connection parts 26.

[0082] Note that the wiring bodies 12b and 12c are overlapped along the thickness direction such that the sheet 30c is interposed between the covered electric wires 20b1-20b12 and the covered electric wires 20c1-20c11. The wiring bodies 12b and 12c may be overlapped along the thickness direction such that the sheets 30b and 30c are not interposed between the covered electric wires 20b1-20b12 and the covered electric wires 20c1-20c11. The wiring bodies 12b and 12c may be overlapped along the thickness direction such that the sheet 30b is interposed between the covered electric wires 20b1-20b12 and the covered electric wires 20c1-20c11. The wiring bodies 12b and 12c may be overlapped along the thickness direction such that both the sheets 30b and 30c are interposed between the covered electric wires 20b1-20b12 and the covered electric wires 20c1-20c11.

[0083] [Embodiment 3] The wiring member according to Embodiment 3 will be described. FIG. 7 is a plan view showing the wiring member 210 according to Embodiment 3. FIG. 8 is an explanatory view showing a state of manufacturing the wiring member 210 according to Embodiment 3. In the description of the present embodiment, the same components as those described so far are denoted by the same reference numerals and the description thereof is omitted.

[0084] The wiring member 210 has two stacked wiring bodies 12d and 12e. The wiring body 12d includes a plurality of coated electric wires 20d1 - 20d4 and a sheet 30d. The wiring body 12e includes a plurality of coated electric wires 20e1 - 20e4 and a sheet 30e. In this example, the sheet 30d and the sheet 30e extend in the same direction from the position of the connection part 26.

[0085] The four coated electric wires 20d1 - 20d4 include two coated electric wires 20d1 and 20d2 belonging to the coated electric wire group G1, one coated electric wire 20d3 belonging to the coated electric wire group G2, and one coated electric wire 20d4 belonging to the coated electric wire group G3. The four coated electric wires 20e1 - 20e4 include one coated electric wire 20e1 belonging to the coated electric wire group G1, two coated electric wires 20e2 and 20e3 belonging to the coated electric wire group G2, and one coated electric wire 20e4 belonging to the coated electric wire group G3. The coated electric wires 20d1 and 20e1 are connected. The coated electric wires 20d2 and 20e2 are connected. The coated electric wires 20d3 and 20e3 are connected.

[0086] At the ends of the coated electric wires 20d3, 20e2, and 20e3, there is a coating layer 24 on the tip side of the core wire 22. The coating layer 24 on the tip side of the core wire 22 at the end of the coated electric wire 20 is sometimes referred to as the tip coating layer 25. The tip coating layer 25 is fixed to the sheets 30d and 30e. Thereby, at positions on both sides adjacent to the exposed core wire 22, the coating layers 24 and 25 are fixed to the sheet 30, so that the exposed core wire 22 at the end of the coated electric wire 20 is also easily positioned at a position crossing the hole 32.

[0087] The tip covering layer 25 is formed as follows, for example. That is, usually when the covering layer 24 is stripped at the end of the covered wire 20, first a cut is formed at an intermediate position of the covering layer 24, and the tip-side covering layer 24 is separated. Then the separated tip-side covering layer 24 is shifted to the tip side of the core wire 22 and eventually comes off the core wire 22. Here, the separated tip-side covering layer 24 is not removed from the core wire 22 but is stopped in a state of being shifted to the tip side of the core wire 22. Thereby, the tip covering layer 25 is formed. In this case, the tip covering layer 25 may have a portion that protrudes toward the tip side of the core wire 22 along the longitudinal direction and does not cover the core wire 22. A portion of the shifted tip-side covering layer 24 that does not cover the core wire 22 may be cut off. In this case, the tip covering layer 25 may cover the core wire 22 in all portions along the longitudinal direction.

[0088] Also, with the wiring member 210 configured as described above, the covered wires 20 can be connected to each other in the region where the hole 32 is formed. It becomes easier to connect the covered wires 20 to each other at a certain position of the sheet 30.

[0089] Also, according to the wiring member 210, there is a tip covering layer 25 on the tip side of the core wire 22 at the ends of the covered wires 20d3, 20e2, and 20e3. Since the tip covering layer 25 is fixed to the sheet 30, it is easy to position the core wire 22 at the end of the covered wire 20 at the position of the hole 32.

[0090] Also, since the sheet 30d and the sheet 30e extend in the same direction from the position of the connecting portion 26, the covered wires 20 arranged in different layers among the covered wires 20 extending in the same direction can be connected to each other.

[0091] Note that in this example, the core wires 22 connected at the connecting portion 26 do not intersect. The core wires 22 connected at the connecting portion 26 may intersect.

[0092] [Modification Example] FIG. 9 is a plan view showing a modified example of the wiring member 10 according to Embodiment 1. The wiring member 310 according to the modified example includes a laminated wiring body 12f and a wiring body 12g.

[0093] A bending region portion 36 is provided in the sheet 30f of the wiring body 12f. The bending region portion 36 is a portion including a portion that bends and extends along the covered electric wire 20. A folded piece 34 of the insulating cover portion is provided at a portion of the bending region portion 36 that bends inward (a portion located on the inner peripheral side in a plan view). Here, the bending region portion 36 is likely to have a poor yield of the sheet 30f. By providing an insulating cover portion at a portion of the bending region portion 36 that bends inward, the yield of the sheet 30f can be improved. Similarly, in the cover 340, the yield can be improved by providing an insulating cover portion at a portion of the bending region portion 36 that bends inward.

[0094] For the configuration of the wiring body 12f other than where the bending region portion 36 is provided, the same configuration as the wiring body 12 in Embodiment 1 can be adopted.

[0095] The covered electric wire 20g in the wiring body 12g is not connected to the covered electric wire 20f in another wiring body 12f at a certain position of the sheet 30g. In this way, the wiring member 310 may have a wiring body 12g that is not connected to another wiring body 12f laminated at a certain position of the sheet 30g. The configuration of this wiring body 12g is not limited to the one in which the covered electric wire 20 is fixed to the sheet 30. The wiring body 12g may be one in which the linear transmission members are kept arranged on the base. For example, the wiring body 12g may be a flexible flat cable (FFC), a flexible printed circuit board (FPC), or the like.

[0096] [Application Example] In Embodiment 2, for example, it is also conceivable that the wiring body 12b is a common wiring body 12 among vehicles with different vehicle types, grades, etc., and the wiring body 12c is a different wiring body 12 among vehicles with different vehicle types, grades, etc. In this case, among the plurality of covered electric wires 20b1-20b10, there may be those not connected to the covered electric wires 20c1-20c11. For example, among the 11 holes 32b shown in FIG. 6, only the core wires 22 of the covered electric wires 20b1-20b10 may be located, and the core wires 22 of the covered electric wires 20c1-20c11 may not be located.

[0097] In addition, the respective configurations described in the above embodiments and respective modification examples can be appropriately combined as long as they do not conflict with each other.
