[Details of the embodiment of the present disclosure]
A specific example of the wiring member of the present disclosure will be described below with reference to the drawings. The present invention is not limited to these exemplifications, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.

[Embodiment 1]
The wiring member according to the first embodiment will be described below. FIG. 1 is a schematic cross-sectional view showing a wiring member 10 according to Embodiment 1. FIG. FIG. 2 is a partially enlarged view of FIG.

The wiring member 10 includes a linear transmission member 20 , a sheet member 30 to which the linear transmission member 20 is fixed, and a cover 50 fixed to the sheet member 30 .

The linear transmission member 20 may be any linear member that transmits electricity, light, or the like. The linear transmission member 20 includes a transmission line body 22 and a coating 24 covering the transmission line body 22 . For example, the linear transmission member 20 may be a general electric wire having a core wire and a coating around the core wire, or may be a shielded wire, an enameled wire, a nichrome wire, an optical fiber, or the like. For example, when the linear transmission member 20 is a general electric wire, the core wire of the general electric wire corresponds to the transmission line main body 22 , and the insulating coating covering the core wire of the general electric wire corresponds to the coating 24 . An insulating coating in a general electric wire is formed by, for example, extruding a resin material such as PVC (polyvinyl chloride) or PE (polyethylene) around a core wire. Various signal lines and various power lines may be used as the linear transmission member 20 for transmitting electricity. A linear transmission member 20 that transmits electricity may be used as an antenna, a coil, or the like that transmits or receives signals or power to or from space.

Here, a plurality of (11 in FIG. 1) linear transmission members 20 are fixed to the sheet material 30 in parallel. The number of linear transmission members 20 may be one or plural. The linear transmission member 20 may be fixed on the sheet material 30 so as to extend along a curved path. A plurality of linear transmission members 20 may be fixed to the sheet material 30 so as to branch off in the middle. A plurality of linear transmission members 20 may be fixed to the sheet material 30 so as to intersect in the middle.

The sheet material 30 is a sheet-like member to which the linear transmission member 20 is fixed on its main surface. By fixing the linear transmission member 20 on the main surface of the sheet material 30, the linear transmission member 20 is held along a predetermined path on the main surface. The sheet material 30 may be flexible enough to be easily bent, or it may be a member having sufficient rigidity to maintain a certain shape.

The sheet of material 30 includes a first securing portion 34 and a second securing portion 36 . The linear transmission member 20 is fixed to the sheet material 30 by directly fixing the covering 24 of the linear transmission member 20 to the first fixing portion 34 . The cover 50 is fixed to the sheet material 30 by directly fixing the cover 50 to the second fixing portion 36 .

Direct fixation means that two members to be fixed are directly attached and fixed without interposing an adhesive or the like separately provided. In direct fixation, for example, it is conceivable that only the resin contained in one of the two members to be fixed is melted to stick and fix, or that the resin contained in both of the two members to be fixed is melted. It is also conceivable that it sticks and is fixed by. In the former case, the melted resin may stick to the other outer surface and become solidified, forming a relatively sharp interface. In the latter case, both resins may mix and form no sharp interface. In particular, when the resins contained in the two members are resins that are easily compatible, such as the same resin material, the two resins may be mixed and a clear interface may not be formed.

Means for forming a directly fixed state are not particularly limited, and various means including known means such as welding, fusing, and welding can be used. For example, when forming a directly fixed state by heat by welding, various welding means such as ultrasonic welding, heating and pressure welding, hot air welding, and high frequency welding can be employed. Further, when a directly fixed state is formed by these means, the two members are brought into a directly fixed state by the means. Specifically, for example, when a directly fixed state is formed by ultrasonic welding, the two members are directly fixed by ultrasonic welding. A portion directly fixed by heat by welding may be referred to as a welded portion, a portion fixed by ultrasonic welding may be referred to as an ultrasonic welded portion, and a portion fixed by heat and pressure welding may be referred to as a heat and pressure welded portion. .

In this example, a first fixing portion 34 and a second fixing portion 36 are provided on one main surface 31 of the sheet material 30 . The linear transmission member 20 is directly fixed to a first fixing portion 34 provided on one main surface 31 of the sheet material 30 . Also, the cover 50 is directly fixed to the second fixing portion 36 provided on the one main surface 31 of the sheet material 30 .

Here, the sheet material 30 has a configuration in which a first fixing portion 34 and a second fixing portion 36 are laminated. A second fixing portion 36 on one main surface 31 of the sheet material 30 is formed so as to partially overlap the first fixing portion 34 . The first fixing portion 34 is a sheet-like member. For example, the first fixing portion 34 is formed in an elongated rectangular shape. The linear transmission member 20 is directly fixed to one main surface 31 of the first fixing portion 34 . The second fixing portion 36 is a sheet-like member formed narrower than the first fixing portion 34 . Here, on one main surface of the first fixing portion 34, the second fixing portion 36 is fixed in an overlapping state at a position avoiding the portion where the linear transmission member 20 is fixed. A cover 50 is directly fixed to one main surface of the second fixing portion 36 .

The manner in which the first fixing portion 34 and the second fixing portion 36 are fixed is not particularly limited, and may be directly fixed or adhesively fixed via an interposition such as an adhesive or double-sided adhesive tape. may be In the example shown in FIG. 2, the first fixing portion 34 and the second fixing portion 36 are directly fixed.

The cover 50 is made of a material different from that of the coating 24 . The cover 50 covers the linear transmission member 20 from the side opposite to the sheet material 30 . Cover 50 includes a body portion 52 and a fixing portion 54 . The body portion 52 is a portion that covers the linear transmission member 20 from the side opposite to the sheet material 30 . The fixed portion 54 is a portion that extends from the body portion 52 and is directly fixed to the sheet material 30 . Here, the body portion 52 collectively covers the plurality of linear transmission members 20 . The fixed portion 54 extends from the edge of the body portion 52 and is directly fixed to the sheet material 30 at the edge of the sheet material 30 . Here, the cover 50 is formed so as to have higher rigidity than the sheet material 30 . The cover 50 can maintain the shape of the wiring member 10 as much as possible.

Since the linear transmission member 20 is directly fixed to the first fixing portion 34, the first fixing portion 34 is more directly fixed to the covering 24 of the linear transmission member 20 than the second fixing portion 36. It is considered a material suitable for

The fact that the first fixing portion 34 is more suitable for direct fixing to the linear transmission member 20 than the second fixing portion 36 can be understood as follows. That is, when the linear transmission member 20 having the same configuration is fixed to the first fixing portion 34 and the second fixing portion 36 under the same conditions, the linear transmission member 20 with respect to the first fixing portion 34 The fixing force is greater than the fixing force of the linear transmission member 20 to the second fixing portion 36 . When direct fixing is adopted as in this example, the fixing force when at least one of the resin surface of the coating 24 and the resin surface of the first fixing portion 34 melts and solidifies and sticks to each other is At least one of the resin surface of the coating 24 and the resin surface of the second fixing portion 36 is melted and solidified, and it may be considered that the fixing force is greater than that in the case where the two are stuck together.

The material constituting the first fixing portion 34 is not particularly limited as long as it satisfies the above conditions, and may be selected in relation to the material constituting the coating 24 . The coating 24 and the first fixing portion 34 are preferably made of the same resin or a similar resin. For example, if the coating 24 is made of resin whose main component is PVC, the first fixing portion 34 may also be made of resin whose main component is PVC.

The first fixing portion 34 is a solid sheet-like member whose interior is evenly filled. This is so that when the first fixing portion 34 and the linear transmission member 20 are directly fixed to each other, the fixing force can be increased even if the contact area between the two becomes small. In particular, since the linear transmission member 20 has a circular cross section, the contact area between the linear transmission member 20 and the first fixing portion 34 tends to be small.

If a material suitable for fixing the linear transmission member 20 is used as the first fixing portion 34 , it may not be suitable for fixing to the cover 50 . Therefore, the second fixing portion 36 is provided so that it can be well fixed to the cover 50 . That is, the second fixing portion 36 is a member that is more suitable for direct fixing to the cover 50 than the first fixing portion 34 .

The fact that the second fixing portion 36 is more suitable for direct fixing to the cover 50 than the first fixing portion 34 can be understood as follows. That is, when the cover 50 having the same configuration is fixed to the first fixing portion 34 and the second fixing portion 36 under the same conditions, the fixing force of the cover 50 to the second fixing portion 36 is It is to be larger than the fixing force of the cover 50 to the fixing portion 34 . When direct fixing is employed as in this example, the fixing force when at least one of the resin surface of the cover 50 and the resin surface of the second fixing portion 36 melts and solidifies and sticks to each other is At least one of the resin surface of the cover 50 and the resin surface of the first fixing portion 34 may be considered to be larger than the fixing force when the two melt and solidify and stick to each other.

The material and structure of the second fixing portion 36 are not particularly limited as long as they satisfy the above conditions, and may be selected in relation to the material and structure of the cover 50 . Due to the space 38 formed in the second fixing part 36 here, the second fixing part 36 is more suitable than the first fixing part 34 for direct fixing to the cover 50 . That is, the cover 50 is directly fixed so as to fill at least part of the space 38 . This creates an anchoring effect between the cover 50 and the second securing portion 36 with the cover 50 directly secured to the second securing portion 36 . In other words, the cover 50 and the second fixing portion 36 are fixed mainly by a physical action called an anchor effect. This allows for a wider range of materials to choose from.

Since the second fixing portion 36 is more suitable for direct fixing to the cover 50 than the first fixing portion 34, it does not mainly use physical action such as an anchor effect, but hydrogen bonding, Van der Waals force, and the like. A method that mainly utilizes a chemical action may also be used. For example, the second fixing portion 36 is made of the same resin material as the cover 50 or a similar resin material, and the first fixing portion 34 is made of a different resin material having low adhesion to the cover 50. Thus, it may be considered that the second fixing portion 36 is chemically more suitable than the first fixing portion 34 for direct fixing to the cover 50 .

The form of the space 38 in the second fixing portion 36 is not particularly limited. For example, the member forming the second fixing portion 36 may be a porous member such as a nonwoven fabric or a resin foam, and each hole of the porous portion may be the space 38 . Further, for example, the member forming the second fixing portion 36 may be a mesh-like member so that the mesh is the space 38 . Further, for example, the member forming the second fixing portion 36 may be a knitted fabric, a woven fabric, or the like, so that a space 38 may be formed between the threads forming the knitted fabric or the woven fabric. Further, for example, a space 38 may be formed by forming a groove, a dent, a notch, or the like on the surface of the solid sheet-like second fixing portion 36, or by forming a hole penetrating the second fixing portion 36. . By filling at least a part of the space 38 with the resin forming the cover 50, an anchor effect is generated between the cover 50 and the second fixing portion 36, and the cover 50 and the second fixing portion 36 are fixed. firmly fixed. At this time, the cover 50 and the second fixing portion 36 are preferably in surface contact over an area larger than the area where one linear transmission member 20 contacts the first fixing portion 34 .

If the second fixing portion 36 has the space 38, the material forming the second fixing portion 36 is not particularly limited. At least part of the space 38 should remain until the melted material of the cover 50 enters the space 38 when directly fixed. For example, the melting point of the material forming the second fixing portion 36 should be about the same as or higher than the melting point of the material of the cover 50 . As a result, it is possible to prevent the second fixing portion 36 from melting before the cover 50 and the space 38 in the second fixing portion 36 being filled with the second fixing portion 36 and disappearing entirely. It is not essential that the melting point of the material forming the second fixing portion 36 is the same as or higher than the melting point of the material forming the cover 50 . Even if the melting point of the material forming the second fixing portion 36 is lower than the melting point of the material forming the cover 50, when the cover 50 and the second fixing portion 36 are directly fixed, the second fixing portion At least a portion of the space 38 can remain until melted material of the cover 50 enters the space 38 upon direct fastening, such as by heating 36 intensively.

It is conceivable that the second fixing portion 36 is made of, for example, PET (polyethylene terephthalate), and the cover 50 is made of nylon, PET, PP (polypropylene), or the like.

The cover 50 is a solid sheet-like member, closed-cell foam, or the like, and is formed to be harder than the sheet material 30 and has high rigidity. For example, the cover 50 is a solid sheet-like member made of a material such as nylon, PET, or PP, or a closed-cell foam, and the sheet material 30 is a solid sheet-like member made of soft PVC and PET. It is a soft member laminated with a nonwoven fabric.

Preferably, the first fixing portion 34 and the second fixing portion 36 are fixed before the cover 50 is fixed to the second fixing portion 36 . The first fixing portion 34 and the second fixing portion 36 may be directly fixed, or may be pasted together with an interposition such as an adhesive or double-sided adhesive tape. In the example shown in FIG. 2, the solid sheet-like first fixing portion 34 fills a part of the space 38 (the space 38 on the side of the first fixing portion 34) in the second fixing portion 36, which is a non-woven fabric. , the first fixing part 34 and the second fixing part 36 are directly fixed. At this time, with the first fixing portion 34 and the second fixing portion 36 fixed, a space 38 remains on the second fixing portion 36 on the side opposite to the first fixing portion 34 side. It is said that By filling the remaining space 38 with the resin forming the cover 50, the cover 50 and the second fixing portion 36 are directly fixed.

The cover 50 and the second fixing portion 36 are directly fixed by being sandwiched between the pressure members 80 and 82 and being pressurized and heated. At least one of the pressure members 80, 82 may be a heating member. When the cover 50 and the second fixing portion 36 are sandwiched between the pressure members 80 and 82, the first fixing portion 34 is also sandwiched.

According to the wiring member 10, the cover 50 is directly fixed to the second fixing portion 36 of the sheet material 30, which is easier to directly fix to the cover 50 than the first fixing portion 34. The cover 50 made of a material different from the coating 24 of the linear transmission member 20 can be satisfactorily attached to the sheet material 30 to which the coating 24 is directly fixed.

A space 38 is formed in the second fixing portion 36 , and the cover 50 is directly fixed so as to fill the space 38 . Therefore, the anchor effect caused by filling the space 38 causes the second fixing portion 36 to move from the first fixing portion 36 to the first fixing portion 36 . It becomes easier to directly fix the cover 50 than the fixing portion 34 .

The linear transmission member 20 is directly fixed to a first fixing portion 34 provided on one main surface 31 of the sheet material 30 , and the cover 50 is a second fixing portion provided on one main surface 31 of the sheet material 30 . Since it is fixed directly to the portion 36, it is not necessary to fix the linear transmission member 20 and the cover 50 on separate major surfaces of the sheet material 30. FIG. On the other hand, since the second fixing portion 36 on the main surface 31 is formed so as to partially overlap the first fixing portion 34, the amount of the second fixing portion 36 used can be reduced.

In the description of this embodiment, the same reference numerals are given to the same components as those described so far, and the description thereof will be omitted. The same applies to the description of each embodiment below.

In this example, the sheet member 130 also has a first fixing portion 134 and a second fixing portion 136 on one main surface 31 . In this example, the first fixing portion 134 on the one main surface 31 partially overlaps the second fixing portion 136 . Specifically, the first fixing portion 134 is, for example, a sheet-like member formed in an elongated rectangular shape. The second fixing portion 136 is a sheet-like member formed in an elongated rectangular shape that is wider than the first fixing portion 134 . Then, the first fixing portion 134 is partially overlaid on one main surface of the second fixing portion 136 and fixed.

In the example shown in FIG. 3, the first fixing portion 134 is fixed to the intermediate portion of one main surface of the second fixing portion 136 while avoiding the side edges. A first fixing portion 134 appears in the middle portion in the width direction of one main surface 31 of the sheet material 130 . A side edge portion of the one main surface of the second fixing portion 136 appears at an end portion in the width direction of the one main surface 31 of the sheet material 130 . A plurality of linear transmission members 20 are directly fixed to the first fixing portion 134 in a row, and the side edge portion of the cover 50 is directly fixed to the side edge portion of one main surface of the second fixing portion 136. .

When the first fixing portion 134 on the one main surface 31 partially overlaps the second fixing portion 136 in this manner, the amount of the first fixing portion 134 used can be reduced.

In the example shown in the second embodiment, there may be a portion where the first fixing portion 134 is not provided in the widthwise intermediate portion of the one main surface 31 of the sheet material 130 . That is, a plurality of narrow first fixing portions 134 may be provided while being spaced apart from the second fixing portion 136 in the width direction. In this case, the intermediate portion of the one main surface of the second fixing portion 136 appears on the one main surface 31 of the sheet material 130 . At this time, the widthwise intermediate portion of the cover 50 may be directly fixed to the intermediate portion of the one main surface of the second fixing portion 36 appearing on the one main surface 31 of the sheet member 130 .

A wiring member according to Embodiment 3 will be described. FIG. 4 is a schematic cross-sectional view showing the wiring member 210 according to the third embodiment.

In this example as well, the sheet material 230 is provided with a first fixing portion 234 and a second fixing portion 236 on one main surface 31 . In this example, a first fixing portion 234 and a second fixing portion 236 are provided on one main surface 31 by partially folding back a sheet-like member forming the sheet material 230 .

Specifically, the sheet material 230 includes a laminated portion 40 in which a first layer forming a first fixing portion 234 and a second layer forming a second fixing portion 236 are laminated. A portion of the laminated portion 40 is folded back on one main surface side of the laminated portion 40 . As a result, the sheet material 230 having the first fixing portion 234 and the second fixing portion 236 provided on the one main surface 31 is formed.

Here, as the sheet-like member before being folded back, a sheet-like member formed so that the laminated portion 40 spreads uniformly is used. That is, the sheet-shaped member forming the first layer and the sheet-shaped member forming the second layer are formed to have the same size and are laminated so that there is no protruding portion to form the laminated portion 40 as a whole. A sheet member is used.

Here, in the laminated portion 40, the layers are laminated so that the first layer forms one main surface and the second layer forms the other main surface. An end portion of the laminated portion 40 is folded back to one main surface side so that the first layer is on the inside. As a result, on the one main surface 31 of the sheet material 230, a first fixing portion 234 appears in the middle portion in the width direction, and a second fixing portion 236 appears in the end portions in the width direction. A plurality of linear transmission members 20 are directly fixed to the first fixing portion 234 in a row, and the side edge portion of the cover 50 is directly fixed to the side edge portion of the one main surface 31 of the second fixing portion 236. there is

A folded portion 42 in which a portion of the laminated portion 40 is folded back is maintained in a folded shape by, for example, being directly fixed to the cover 50 . Further, for example, the folded portion 42 is maintained in a folded shape due to the crease. A folded shape maintaining portion that maintains the folded shape may be separately provided in the folded portion 42 . As the folded shape maintaining portion, for example, the surfaces facing each other in the folded portion 42 (the main surfaces of the first layer in the example shown in FIG. 3) are directly fixed to each other, or an inclusion such as an adhesive or double-sided adhesive tape is used. It is possible to employ a configuration in which the adhesive is fixed through the . Further, for example, as the folded shape maintaining portion, a configuration in which both sides of the folded portion 42 sandwiching the crease are sewn with a thread or the like, or a configuration in which the portions are fastened with a stapler or the like can be adopted.

In this way, the sheet material 230 includes the laminated portion 40 in which the first layer forming the first fixing portion 234 and the second layer forming the second fixing portion 236 are laminated, and part of the laminated portion 40 is laminated.

Also, the cover 350 is directly fixed to the second fixing portion 336 provided on the other main surface 32 of the sheet material 330 . At this time, the shape of the fixing portion 354 of the cover 350 is different from the shape of the fixing portion 54 of the cover 50 . The fixed portion 354 extends from the edge portion of the main body portion 52 toward the other main surface 32 . At this time, the fixing portion 354 is connected to the main body portion 52 and includes a base end portion 355 covering the one main surface 31 of the sheet material 330, a tip end portion 356 covering the other main surface 32 of the sheet material 330, the base end portion 355 and the tip end portion. 356 and a connecting portion 357 that connects 356 . The connecting portion 357 is bent from the one main surface 31 side of the sheet material 330 toward the other main surface 32 side. The distal end portion 356 is directly fixed to the second fixing portion 336 provided on the other main surface 32 of the sheet member.

A first fixing portion 334 is provided on one main surface 31 of the sheet material 330 , and a second fixing portion 336 is provided on the other main surface 32 . As the sheet material 330, a sheet-like member similar to the sheet-like member before being folded in the third embodiment is used. That is, as the sheet material 330, a sheet-like member in which a first layer forming the first fixing portion 334 and a second layer forming the second fixing portion 336 are laminated and the laminated portion spreads uniformly is used as it is. there is Thus, in this example, as the sheet material 330, the laminated portion 40 in which the first layer forming the first fixing portion 334 and the second layer forming the second fixing portion 336 are laminated is a sheet that spreads uniformly. The shaped member can be used as it is.

As the sheet material 330, a sheet material other than the sheet-like member in which the laminated portion 40 spreads uniformly may be employed. For example, the sheet material 30 described in the first embodiment may be used in the opposite direction to the front and back. Further, for example, the sheet members 130 and 230 described in the second and third embodiments may be used with their front and back directions unchanged.

The distal end portion 356 of the fixing portion 354 is preferably fixed directly to a position avoiding the portion overlapping the linear transmission member 20 in the second fixing portion 336 provided on the other main surface 32 of the sheet material 330 . This is because when the cover 350 and the sheet material 330 are directly fixed, the linear transmission member 20 does not need to be sandwiched between the pressure members 80 and 82 as shown in FIG.

A base end portion 355 of the fixing portion 354 may or may not be directly fixed to the one main surface 31 of the sheet material 330 . For example, when the cover 350 and the sheet material 330 are directly fixed, as shown in FIG. can be

In the example shown in FIG. 5 , on the one main surface 31 of the sheet material 330 , the portion of the fixing portion 354 that faces the base end portion 355 is the first fixing portion 334 . In this case, when sheet material 330 and cover 350 are directly fixed on one main surface 31 of sheet material 330 , the fixing strength is It becomes weaker than the fixing strength of the fixed portion (the portion where the second fixing portion 336 and the tip portion 356 are directly fixed). When the cover 350 of this example is adopted as the sheet material 330 for the sheet material 130 described in the second embodiment, one main surface 31 of the sheet material 130 faces the base end portion 355 of the fixed portion 354 . The part is the second fixing part 336 . In this case, when sheet material 130 and cover 350 are directly fixed on one main surface 31 of sheet material 130 , the fixing strength is The fixing strength can be about the same as that of the fixed portion (the portion where the second fixing portion 136 and the distal end portion 356 are directly fixed).

When the fixing portion 354 of the cover 350 is fixed to the other main surface 32 of the sheet material 330 as in this example, the projection dimension of the fixing portion 354 in the front-rear direction of the body portion 52 of the cover 350 increases. At this time, if the base material of the cover 350 is a sheet-like member having high rigidity, the projecting dimension of the fixing portion 354 in the front and back direction of the main body portion 52 in the cover 350 is increased, so that the rigidity of the wiring member 310 is increased. This makes it easier to maintain the shape of the wiring member 310 .

Note that the configurations described in the above embodiments and modifications can be appropriately combined as long as they do not contradict each other.
