Details of Embodiment of Present Disclosure

Specific examples of a wiring member of the present disclosure are described hereinafter with reference to the drawings. The present disclosure is not limited to these examples, but is indicated by claims, and it is intended that meanings equivalent to claims and all modifications within a scope of claims are included.

A wiring member10according to an embodiment 1 is described hereinafter.FIG.1is a plan view illustrating the wiring member10according to the embodiment 1.FIG.2is a cross-sectional view of the wiring member10cut along a II-II line inFIG.1.FIG.3is an explanation diagram illustrating a manufacture of the wiring member10according to the embodiment 1. A cover40is omitted inFIG.1.

The wiring member10includes a plurality of cover wires20, a sheet30, and the cover40. The sheet30is formed into a flat shape as a whole. The plurality of cover wires20are fixed on the sheet30, thus the wiring member10is kept in a flat state, the cover wire20fixed to the sheet30is referred to as a wiring body12in some cases. The cover40covers the cover wire20from a side opposite to the sheet30.

The plurality of cover wires20are members electrically connecting components in a vehicle. A connector, for example, is provided on an end portion of the cover wire20. This connector is connected to a connector provided in the other side component, thus the cover wire20is connected to the other side component. That is to say, the present wiring member10is used as a wiring member10electrically connecting various types of component in a vehicle, for example. The connector may be fixed to the sheet30.

A route of the plurality of cover wires20is set in accordance with a position of a component as a connection destination of the cover wire20. The plurality of cover wires20are fixed to the sheet30, thus the plurality of cover wires20are kept in a form following a wiring route corresponding to a position of a component as a connection destination of each cover wire20. The plurality of cover wires20may be fixed to the sheet30in a state where a branch wire part is branched from a main wire part.

The cover wire20includes a core wire22and a covering layer24. The core wire22includes one or a plurality of strands. The strand is made up of a conductor such as copper or aluminum formed into a wire-like shape. The covering layer24covers around the core wire22. The covering layer24is an insulation body such as resin. The covering layer24is formed by extrusion molding a softened insulation material around the core wire22, for example.

The cover wire20may be various kinds of signal lines or various kinds of power lines. Some of the cover wires20, for example, may be used as an antenna or coil, for example, transmitting or receiving a signal or electrical power to or from a space.

FIG.1illustrates six cover wires20. The six cover wires20are referred to as cover wires20a1to20a6in some cases when they needs to be distinguished.

The sheet30keeps the plurality of cover wires20in a state be being arranged side by side. The plurality of cover wires20are fixed to a main surface of the sheet30. The sheet30may be a resin sheet. For example, the sheet30may be formed of resin such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET). The sheet30is also considered a non-woven cloth or a foamed sheet, for example. The sheet30may have a single layer structure, or may also have a multilayer structure. The sheet30may include a metal layer. The sheet30is an example of a first sheet.

A fixing state of fixing the cover wire20to the sheet30is not particularly limited as long as the cover wire20is fixed to the sheet30. Applicable as the fixing state are a contact area fixation and a non-contact area fixation, or both fixations may be used together. Herein, the contact area fixation indicates that a portion where the cover wire20and the sheet30have contact with each other is stuck and fixed. The non-contact area fixation is a fixing state which is not the contact area fixation, and indicates that a sewing thread, a cover, or an adhesive tape presses the cover wire20toward the sheet30or sandwiches the cover wire20and the sheet30to keep them in a fixing state. In the description hereinafter, the cover wire20and the sheet30are in the state of the contact area fixation.

Applicable as the configuration of the contact area fixation are a contact area indirect fixation and a contact area direct fixation, or both fixations may also be used together in different regions. Herein, the contact area indirect fixation indicates that the cover wire20and the sheet30are indirectly stuck and fixed via an adhesive agent, a gluing agent, and a double-sided adhesive tape provided therebetween. The contact area direct fixation indicates that the cover wire20and the sheet30are directly stuck and fixed without an intervention of the adhesive agent, for example, which is separately provided. Considered in the contact area direct fixation is that resin included in at least one of the cover wire20and the sheet30is melted, thus the cover wire20and the sheet30are stuck and fixed, for example.

In forming the state of such a contact area direct fixation, the resin is considered to be melted by heat or a solvent, for example. That is to say, the state of the contact area direct fixation may be the state of the contact area direct fixation by the heat or the state of the contact area direct fixation by the solvent. The contact area direct fixation by the heat is preferable.

At this time, a means of forming the state of the contact area direct fixation is not particularly limited, but a known means such as welding, fusion, and melting joint can be used. For example, when the state of the contact area direct fixation by the heat is formed by welding, various welding means such as ultrasonic welding, heating-pressurizing welding, hot air welding, and high frequency welding can be adopted. When the state of the contact area direct fixation is formed by these means, the cover wire20and the sheet30are in the state of the contact area direct fixation by these means. Specifically, when the state of the contact area direct fixation is formed by the ultrasonic welding, for example, the cover wire20and the sheet30are in the state of the contact area direct fixation by the ultrasonic welding.

In the description hereinafter, the cover wire20and the sheet30are in the state of the contact area direct fixation.

Each cover wire20may be fixed to the sheet30at a plurality of positions at intervals along a longitudinal direction. Each cover wire20may be wholly fixed to the sheet30continuously along a longitudinal direction. Herein, the covering layer24of the cover wire20and the sheet30are fixed by the contact area direct fixation, thus a portion of the cover wire20fixed to the sheet30is a portion where the covering layer24is provided.

A hole32is formed in the sheet30. The hole32is formed in a position in the sheet30deviating to a lateral side from a route along which the cover wire20extends straight. A width dimension of the sheet30is partially larger in a portion where the hole32is formed than in a portion where the hole32is not formed. The plurality of holes32are disposed collectively in one position. Accordingly, the plurality of holes32may be easily covered by one insulation cover part. Needless to say, the hole32may be located on the route along which the cover wire20extends straight. The plurality of holes32may be dispersedly disposed.FIG.1illustrates four holes32. When the four holes32need to be distinguished, they are referred to as the holes32a1to32a4in some cases.

A connection part26is located in a region where the hole32is formed. The connection part26is a portion where the core wires22in the plurality of cover wires20are electrically connected.FIG.1illustrates two connection parts26. When the two connection parts26need to be distinguished, they are referred to as the connection parts26a1and26a2in some cases.

The cover wires20a1,20a2, and20a3are connected in the connection part26a1. The cover wires20a1,20a2, and20a3are connected in an intermediate portion. Herein, a state where the cover wire20is connected in the intermediate portion indicates a case where both end portions of the cover wire20are connected to the other connection destination, respectively. Intermediate portions of the cover wires20a1,20a2, and20a3are peeled, thus the core wires22are exposed, for example. The exposed core wires22are connected to form the connection part26. The connection part26a1is located in a region where the hole32a1is formed.

A state where the connection part26is located in a region where the hole32is formed indicates that the connection part26is located in a position of the hole32in a plan view or the connection part26is located on a periphery of the hole32in a plan view. The covering layer24is fixed to the periphery of the hole32in the sheet30in a position near the exposed core wire22. The exposed core wire22including the connection part26is not fixed to the sheet30but can be moved. Thus, the connection part26may be located in a position slightly deviating from the hole32in a plan view. The connection part26may be located inside or outside the hole32in a thickness direction of the sheet30.

The cover wires20a4and20a5are connected in the connection part26a2. The cover wires20a4and20a5are connected in intermediate portions. The intermediate portions of the cover wires20a4and20a5are peeled, thus the core wires22re exposed, for example. The exposed core wires22are connected to form the connection part26a2. The connection part26a2is located in a region where the hole32a3is formed.

The core wires22of the plurality of cover wires20intersect with each other in each connection part26. Herein, the plurality of cover wires20changes their arrangement and cross the hole32, thus the core wires22intersect with each other. An example of the connection part26a1is described hereinafter.

In the example illustrated inFIG.1, the cover wires20a1,20a2, and20a3are arranged in this order from an upper side on a left side of the hole32a1in the connection part26a1. The cover wires20a1,20a2, and20a3are arranged in an order of the cover wires20a3,20a2, and20a1from the upper side on a right side of the hole32a1. Accordingly, directions in which each of the cover wires20a1,20a2, and20a3cross the hole32a1can be different from each other, thus the core wires22of the cover wires20a1,20a2, and20a3can cross each other at a position of the hole32a1. The order of the cover wires20a3,20a2, and20a1returns to the order of the cover wires20a1,20a2, and20a3from the upper side in a tip portion on the right side of the hole32a1. Thus, the cover wires20a1,20a2, and20a3cross each other at a portion where the covering layer24is located to return the arrangement order. However, the cover wires20a3,20a2, and20a1may extend in this order from the upper side in the tip portion on the right side of the hole32a1.

The core wires22are welded in each connection part26. Accordingly, the core wires22are kept in a state of being connected to each other. The welding method is not particularly limited, but various welding method such as ultrasonic welding, resistance welding, or laser welding can be adopted. The connection state of the core wires22is not limited to welding, but various types of connection state can be adopted. For example, a terminal may be crimped to the core wires22to connect the core wires22.

The core wires22are connected in the connection part26as described hereinafter, for example. An example of the connection part26a2is described hereinafter. Firstly, the cover wires20a4and20a5are wired and fixed on the sheet30along a predetermined route. At this time, the predetermined route includes a route crossing the bole32a3. That is to say, the cover wires20a4and20a5are disposed to cross the hole32a3. The portion of the cover wires20a4and20a5crossing the hole32a3is not fixed to the sheet30. A peripheral part of the hole32a3in the cover wires20a4and20a5is fixed to the sheet30. The portion of each of the cover wires20a4and20a5crossing the hole32a3is peeled. Accordingly, the core wire22of each of the cover wires20a4and20a5crossing the hole32a3is exposed. The exposed core wire22is positioned to cross the hole32a3. In this state, a jig for connection is placed on the core wires22of the cover wires20a4and20a5, thereby connecting the core wires22of the cover wires20a4and20a5.

The jig is different depending on a connection method. When the connection method is ultrasonic welding, for example, the jig is a horn and an anvil of a ultrasonic welding machine. When the connection method is a terminal, for example, the jig is a crimper and an anvil of a terminal crimper. The core wire22is located in a position of the hole32, thus these jigs can sandwich the core wires22from both sides in the thickness direction of the sheet30in a position of the hole32.

A region in the cover wire20where the core wire22is exposed inFIG.1is larger than the hole32. That is to say, the core wire22is exposed also in a portion of the cover wire20located on the periphery of the hole32. A region in the cover wire20where the core wire22is exposed may be equal to or smaller than the hole32.

One of the cover wires20a1,20a2, and20a3is a first cover wire, and the other one of them is a second cover wire. In the similar manner, one of the cover wires20a4and20a5is a first cover wire, and the other one of them is a second cover wire. It is sufficient that at least one first cover wire is included. It is sufficient that at least one second cover wire is included.

Herein, holes32a2and32a4where the connection part26is not located are provided. However, the holes32a2and32a4where the connection part26is not located need not be provided. The connection part26may be located in all of the holes32.

The cover wire20a6is not connected to the cover wires20a1,20a2,20a3,20a4, and20a5in a certain position in the sheet30. The cover wire20a6is an example of a wire-like transmission member which is not connected to the first cover wire and the second cover wire in a certain position where the sheet30is located. The wire-like transmission member may be a bare conductive wire, a shielded wire, a twisted wire, an enamel wire, a nichrome wire, a coaxial wire, or an optical fiber in addition to the cover wire20described above. The wire-like transmission member may be a wire-like member transmitting an electrical power or light, for example. The wire-like transmission member20may be a single wire-like object or a composite object of a plurality of wire-like objects (a twisted wire and a cable made up of a plurality of wire-like objects covered by a sheath). It is sufficient that at least one wire-like transmission member is included.

The cover40may be wholly or partially overlapped with the sheet30. The cover40may be a resin sheet. For example, the cover40may be formed by resin such as PVC, PE, PP, or PET in the manner similar to the sheet30. One of the sheet30and the cover40may be softer than the other one. The softness herein, or rigidity conversely, may also be evaluated by Rockwell hardness, for example. For example, it is applicable that the cover40is formed by a material such as rigid PVC, nylon, PET, or PP, and the sheet30is a soft member made up of a sheet-like member formed by soft PVC and a non-woven cloth formed by PET stacked on each other.

The wiring member10is provided with an insulation cover part covering the connection part26. The insulation cover part includes a portion formed by folding a part of the sheet30. In the present example, a side of the sheet30on which the cover wire20is disposed is covered by the cover40. A side of the sheet30on which the cover wire20is not disposed is covered by a fold piece34of the sheet30. Accordingly, the insulation cover part includes the cover40and the fold piece34of the sheet30.

The fold piece34is folded back along a fold line L. A portion of the sheet30where the cover wire20is fixed is referred to as an electrical wire fixing part in some cases. Herein, the fold piece34is provided adjacent to a portion of the sheet30where the hole32is formed along the width direction. The fold piece34may be provided adjacent to a portion of the sheet30where the hole32is formed along the longitudinal direction. It is also applicable that the two fold pieces34are provided and cover a portion of the sheet30where the hole32is formed from both sides.

The fixing state of the sheet30and the cover40is not particularly limited, however, various types of fixing state of the sheet30and the cover wire20described above can be adopted. The fixing state of the sheet30and the cover40may be the same as or different from the fixing state of the sheet30and the cover wire20.

The fixing state of the electrical wire fixing part and the fold piece34is not particularly limited, however, various types of fixing state of the sheet30and the cover wire20described above can be adopted. The fixing state of the electrical wire fixing part and the fold piece34may be the same as or different from the fixing state of the sheet30and the cover wire20and the fixing state of the sheet30and the cover40.

According to the wiring member10having the above configuration, the cover wires20can be connected in the region where the hole32is formed. The cover wires20are easily connected in a certain position in the sheet30. The cover wires20fixed to the same sheet30can be connected. The core wires22of the cover wires20intersect with each other, thus the core wire22can be easily connected.

The core wires22are welded in the connection part26, thus a component for connecting the core wires22is unnecessary in the connection part26. However, the core wires22may be connected using the other component such as a terminal in the connection part26.

The connection part26is provided in the intermediate portion of the cover wire20, thus an intermediate splice can be simply provided in a position where the sheet30is located. An end portion of one of the cover wires20a1to20a3may be connected in the connection part26. In the similar manner, an end portion of one of the cover wires20a4and20a5may be connected in the connection part26.

The insulation cover part is provided, thus a short circuit can be suppressed in the connection part26. The insulation cover part includes a portion formed by folding a part of the sheet30, thus the insulation cover part can be simply provided.

A wiring member according to an embodiment 2 is described.FIG.4is a plan view illustrating a wiring member110according to the embodiment 2.FIG.5is a cross-sectional view of the wiring member cut along a V-V line inFIG.4.FIG.6is an explanation diagram illustrating a manufacture of the wiring member110according to the embodiment 2. In the following description of the present embodiment, the same reference numerals are assigned to the similar constituent elements described above, and the description thereof will be omitted.

The wiring member110includes a plurality of wiring bodies12band12c. The wiring body12bincludes a plurality of cover wires20b1to20b12and a sheet30b. The wiring body12cincludes a plurality of cover wires20c1to20c11and a sheet30c. The plurality of wiring bodies12band12care partially stacked.

Twelve cover wires20b1to20b12are illustrated in the wiring body12b. The twelve cover wires20b1to20b12are divided into three groups of cover wire groups G1, G2, and G3described hereinafter. That is to say, the cover wire group G1is a group of the cover wire20in which the core wires22are exposed in the intermediate portions. One cover wire20b1belongs to the cover wire group G1. The cover wire group G2is a group of the cover wire20in which the core wires22are exposed in the end portions. Nine cover wires20b2to20b10belong to the cover wire group G2. The cover wires20b2to20b7and the cover wires20b8to20b10extend from the connection part26in directions opposite to each other. The cover wire group G3is a group of the cover wire20in which the core wires22are not exposed in a certain position of the sheet30. There is a case where a connector to which the end portion of the cover wire group G3is connected is disposed on the sheet30. Two cover wires20b11and20b12belong to the cover wire group G3.

A hole32bis formed in the sheet30b.FIG.6illustrates eleven holes32b. The eleven holes32bare formed in position corresponding to the exposed core wires22in the cover wires20b1to20b10. Two holes32bare formed in positions corresponding to the exposed core wires22in the cover wire20b1.

Eleven cover wires20c1to20c11are illustrated in the wiring body12c. All of the eleven cover wires20c11and20c11belong to the cover wire group G2. A hole32cis formed in the sheet30c.FIG.6illustrates eleven holes32c. The eleven holes32care formed in position corresponding to the exposed core wires22in the cover wires20c1to20c11. The hole32band the hole32care arranged in the same arrangement. Accordingly, the sheet30band the sheet30ccan be stacked so that all of the corresponding holes32band32coverlap with each other.

The cover wires20c1and10c2are connected to the cover wire20b1. The cover wires20c3to20c11are connected to the cover wires20b2to20b10, respectively. Each connection part26is provided on the end portion of the cover wire20. The end portion of the cover wire20indicates a portion where a connection destination is not provided on a further tip side thereof.

The plurality of connection parts26are arranged in a step-like form. The connection part26of the cover wire20b1and the cover wires20c1and20c2serves as a top part. Each connection part26of the cover wires20b2to20b7and the cover wires20c3to20c8is arranged on a left side of the top part. Each connection part26of the cover wires20b2to20b7and the cover wires20c3to20c8is located away from the top part along a longitudinal direction of the sheet30bwith a distance from the top part along a width direction of the sheet30b. Each connection part26of the cover wires20b8to20b10and the cover wires20c9to20c11are arranged on a right side of the top part. Each connection part26of the cover wires20b8to20b10and the cover wires20c9to20c11is located away from the top part along the longitudinal direction of the sheet30bwith a distance from the top part along the width direction of the sheet30b.

The number of the connection parts26disposed on both sides of the top part is different, but may be the same as each other. A width dimension of a portion extending to the both sides of the top part is different in the sheet30b. That is to say, in the example illustrated inFIG.4, the number of the connection parts26on the right side of the top part is smaller, thus the width dimension of a portion of the sheet30bextending to the right side of the top part is smaller than that of a portion thereof extending to the left side of the top part. The width dimension of the portion extending to the both sides of the top part may be the same in the sheet30b.

The sheet30band the sheet30cextend from the position of the connection part26in direction intersecting with each other. Accordingly, the wiring body12band the wiring body12ccan be easily branched in different directions. Herein, the hole32bis formed in the intermediate portion of the sheet30bin the longitudinal direction. The hole32cis formed in the end portion of the sheet30cin the longitudinal direction. The sheet30cextends in a direction intersecting with the longitudinal direction of the sheet30b(herein, a direction perpendicular to the longitudinal direction thereof). Needless to say, the hole32bmay be formed in a position of the end portion of the sheet30bin the sheet30b. In this case, the plurality of wiring bodies12are connected at positions of the end portions. The hole32cmay be formed in a position of the intermediate portion of the sheet30cin the sheet30c. In this case, the plurality of wiring bodies12are connected at positions of the intermediate portions.

All of the cover wires20c1to20c11located on the end portion of the sheet30care connected to the cover wires20b1to20b10. Accordingly, the connection part26of the wiring body12band the wiring body12ccan double for portion of a so-called wire-to-wire connection using a connector.

The cover wires20c1to20c11extend to one side (a lower side inFIG.4) from the connection part26. The cover wires20b11and10b12are disposed on the other side (an upper side inFIG.4) of the connection part26. That is to say, in the wiring body12b, the cover wires20b11and20b12which are not used for connection to the wiring body12care disposed in a position deviating to a lateral side of the all the holes32bused for connection to the wiring body12cwhen seen from the longitudinal direction. Accordingly, the intersection of the cover wires20b11and20b12which are not used for connection to the wiring body12cand the cover wires20c1to20c11is suppressed.

The insulation cover part partitions the connection part26in a position between the plurality of holes32in one sheet30. Herein, as illustrated inFIG.5, the cover40is joined to a portion of the sheet30cbetween the holes32(a joint part A1). A fold part in the sheet30bis joined to a portion of the sheet30bbetween the holes32(a joint part A2). Furthermore, a portion of the sheet30bbetween the holes32and a portion of the sheet30cbetween the holes32are joined (a joint part A3). Accordingly, a short circuit caused by a direct contact between the plurality of connection parts26is suppressed. Furthermore, a short circuit between the plurality of connection parts26via water, for example, is also suppressed.

Also according to the wiring member110having the above configuration, the cover wires20can be connected in the region where the hole32is formed. The cover wires20are easily connected in a certain position in the sheet30.

According to the wiring member110, the cover wires20fixed to the different sheets30band30ccan be connected. The connection part26is provided on the end portion of the cover wire20, thus the end portion of the electrical wire can be connected. The sheet30band the sheet30cextend from the position of the connection part26in directions intersecting with each other, thus the branch extending in the different direction is simply formed.

The plurality of connection parts26are provided, and arranged in the step-like form, thus the intersection of the cover wires20b1to20b10and the cover wires20c1to20c11at the position of the covering layer24is suppressed. Accordingly, increase in thickness dimension of the wiring member110can be suppressed. However, the plurality of connection parts26need not be arranged in a step-like form. The plurality of connection parts26are arranged in a step-like form on both sides from the top part, but may be arranged in a step-like form only on one side from the top part.

The cover wires20c1to20c11extend on one side from the connection parts26, and the cover wires20b11and20b12are disposed on the other side of the connection part26, thus the intersection of the cover wires20b11and20b12and the cover wires20c1to20c11is suppressed. Accordingly, increase in thickness dimension of the wiring member110can be suppressed.

The insulation cover part partitions the connection part26in a position between the plurality of holes32, thus a short circuit of the plurality of connection parts26is suppressed.

The wiring body12band the wiring body12eoverlap with each other so that the sheet30cintervenes between the cover wires20b1to20b12and the cover wires20c1to20c11along the thickness direction. The wiring body12band the wiring body12cmay overlap with each other so that the sheets30band30cdo not intervene between the cover wires20b1to20b12and the cover wires2001to20c11along the thickness direction. The wiring body12band the wiring body12cmay overlap with each other so that the sheet30bintervenes between the cover wires20b1to20b12and the cover wires20c1to20c11along the thickness direction. The wiring body12band the wiring body12cmay overlap with each other so that both the sheets30band30cintervene between the cover wires20b1to20b12and the cover wires20c1to20c11along the thickness direction.

A wiring member according to an embodiment 3 is described.FIG.7is a plan view illustrating a wiring member210according to the embodiment 3.FIG.8is an explanation diagram illustrating a manufacture of the wiring member210according to the embodiment 3. In the following description of the present embodiment, the same reference numerals are assigned to the similar constituent elements described above, and the description thereof will be omitted.

The wiring member210is made up of two wiring bodies12dand12estacked on each other. The wiring body12dincludes a plurality of cover wires20d1to20d4and a sheet30d. The wiring body12eincludes a plurality of cover wires20e1to20e4and a sheet30e. In the present example, the sheet30dand the sheet30eextend from the position of the connection part26in the same direction.

Four cover wires20d1to20d4include two cover wires20d1and20d2belonging to the cover wire group G1, one cover wire20d3belonging to the cover wire group G2, and one cover wire20d4belonging to the cover wire group G3. Four cover wires20e1to20e4include one cover wire20e1belonging to the cover wire group31, two cover wires20e2and20e3belonging to the cover wire group G2, and one cover wire20e4belonging to the cover wire group G3. The cover wires20d1and20e1are connected to each other. The cover wires20d2and20e2are connected to each other. The cover wires20d3and20e3are connected to each other.

The covering layer24is located closer to a tip side of the end portions of the cover wires20d3,20e2, and20e3than the core wire22. The covering layer24located closer to the tip side of the end portion of the cover wire than the core wire22is referred to as a tip covering layer25in some cases. The tip covering layer25is fixed to the sheets30dand30e. The covering layers24and25are fixed to the sheet30in the positions on both sides of the exposed core wire22, thus the exposed core wire22can be easily positioned in the position crossing the hole32also in the end portion of the cover wire20.

The tip covering layer25is formed as described hereinafter, for example. That is to say, normally, when the covering layer24is peeled in the end portion of the cover wire20, a cut line is firstly formed inn an intermediate position of the covering layer24, and the covering layer24on the tip side is separated. Then, the separated covering layer24on the tip side is moved to the tip side of the core wire22and comes out of the core wire22. Herein, the separated covering layer24on the tip side is not taken out of the core wire22but is stopped after being moved to the tip side of the core wire22. The tip covering layer25is thereby formed. In this case, the tip covering layer25may include a portion protruding to the tip side of the core wire22along the longitudinal direction and does not cover the core wire22. A portion of the moved covering layer24on the tip side which does not cover the core wire22may be removed. In this case, the tip covering layer25may cover the core wire22in the whole portion along the longitudinal direction.

Also according to the wiring member210having the above configuration, the cover wires20can be connected in the region where the hole32is formed. The cover wires20are easily connected in a certain position in the sheet30.

According to the wiring member210, the tip covering layer25is located closer to the tip side of the end portions of the cover wires20d3,20e2, and20e3than the core wire22. The tip covering layer25is fixed to the sheet30, thus the core wire22on the end portion of the cover wire20is easily positioned in the position of the hole32.

The sheet30dand the sheet30eextend from the position of the connection part26in the same direction, thus the cover wires20disposed on the different layers in the cover wires20extending in the same direction can be connected to each other.

In the present example, the core wires22connected in the connection part26do not intersect with each other. The core wires22connected in the connection part26may intersect with each other.

Modification Example

FIG.9is a plan view illustrating a modification example of the wiring member10according to the embodiment 1. A wiring member310according to the modification example includes a wiring body12fand a wiring body12gstacked on each other.

A bending region part36is provided in a sheet30fof the wiring body12f. The bending region part36is a portion including a portion extending to be bended along the cover wire20. The fold piece34of the insulation cover part is provided in a portion inwardly bended (a portion located on an inner periphery side in a plan view) in the bending region part36. Herein, a yield of the sheet30ftends to be reduced in the bending region part36. The insulation cover part is provided in the portion inwardly bended in the bending region part36, thus the yield of the sheet30fcan be improved. In the similar manner, also in a cover340, the insulation cover part is provided in the portion inwardly bended in the bending region part36, thus the yield of the sheet340can be improved.

A configuration similar to the wiring body12in the embodiment 1 can be adopted to a configuration of the wiring body12fexcept that the bending region part36is provided.

The cover wire20gof the wiring body12gis not connected to the cover wire20fof the other wiring body12fin a certain position in the sheet30g. In this manner, the wiring body12gwhich is not connected to the other wiring body12fmay be stacked in a certain position of the sheet30gin the wiring member310. The configuration of the wiring body12gis not limited to the configuration that the cover wire20is fixed to the sheet30. The wiring body12gmay have a configuration that wire-like transmission members are kept in a state of being arranged on a base. For example, the wiring body12gmay be a flexible flat cable (FFC) or flexible print circuits (FPC).

Application Example

It is also considered that in the embodiment 2, the wiring body12bserves as the wiring body12commonly used in vehicles of different types or grades, and the wiring body12cserves as the wiring body12different in vehicles of different types or grades. In this case, the plurality of cover wires20b1to20b10may include a cover wire which is not connected to the cover wires20c1to20c11. For example, it is also applicable that the eleven holes32billustrated inFIG.6may include a hole on which only the core wires22of the cover wires20b1to20b10are located, and the core wires22of the cover wires20c1to20c11are not located.

The configurations described in the embodiments and modification examples thereof can be appropriately combined as long as they are not contradictory.
