The nonwoven material is a planar member 4 widening in a predetermined region. Since the electric wires 2 are installed in the vehicle in a state sandwiched between the planar members 4 having soundproof performance, the workability in the assembly work to the vehicle is improved. Moreover, the noise can be inhibited from transmitting inside the vehicle by the planar members 4 overlapped so as to sandwich the electric wires 2.

Description

  The present invention relates to a wire harness.

  A vehicle represented by an automobile is equipped with various electric transmission devices such as a motor, a fan, an electronic control unit for controlling them, various sensors, and a switch. In order to electrically connect each of these electric transmission devices, a wire harness composed of electric wires is disposed in each part of the vehicle.

  In addition, a soundproof material is installed on the floor portion of the passenger compartment of the vehicle. The floor portion has a structure in which a floor carpet is laid on an iron plate constituting a vehicle. For this reason, traveling sound (road noise), engine sound, and the like derived from contact between the tire and the road surface during traveling are easily transmitted to the vehicle interior through the floor portion. Therefore, in order to suppress the transmission of these sounds into the vehicle and realize a comfortable vehicle space with less noise, the soundproofing material is installed between the iron plate and the floor carpet.

  If such an electric wire and a soundproofing material are separately assembled to the vehicle, the assembling work will be troublesome. Here, Patent Document 1 discloses a wire harness having a structure in which an electric wire bundle is sandwiched between a base body which is a hard plate material and a covering body made of a nonwoven fabric having soundproofing properties. In the wire harness of Patent Document 1, a soundproof material (cover) and an electric wire are integrally assembled to a vehicle.

JP 2010-027242 A

  However, in the wire harness described in Patent Document 1, since one member of the two members sandwiching the electric wire is a hard plate material, the wire harness is not a specification having sufficient soundproofing properties. That is, even if the wire harness described in Patent Document 1 is mounted on a vehicle, the wire harness cannot sufficiently suppress noise from being transmitted to the vehicle interior.

  The present invention has been made in view of the above problems, and can improve the workability of the work of assembling the soundproofing material and the electric wire to the vehicle, and sufficiently suppress the sound from being transmitted to the inside of the vehicle. An object of the present invention is to provide a highly soundproof wire harness that can be used.

  In order to solve the above-mentioned problem, a wire harness according to a first aspect of the present invention is overlapped with an electric wire and a part of the electric wire sandwiched so that both ends of the electric wire are exposed, and in a region around the electric wire. A planar member made of a non-woven material spreading in a planar shape.

  A wire harness according to a second aspect of the present invention is the wire harness according to the first aspect of the present invention, wherein at least a part of the outer edge portion of the planar member is joined by hot pressing.

  A wire harness according to a third aspect of the present invention is the wire harness according to the first aspect of the present invention, characterized in that at least a part of the planar member sandwiching the electric wire is joined by hot pressing. To do.

  A wire harness according to a fourth invention is the wire harness according to any one of the first to third inventions, and is formed in contact with or integrally with the planar member. It further includes a positioning member that supports the extended electric wire and that can be fitted into a concave shape provided in the arrangement target site.

  According to the first invention, the wire harness has a structure in which planar members made of a non-woven material are overlapped with a part of the electric wire interposed therebetween. Since the electric wire is assembled to the vehicle in a state of being sandwiched between the non-woven material planar members having soundproofing properties, the workability of the electric wire and soundproofing material assembling work can be improved. Moreover, since the installation target part can be covered with the planar member made of the nonwoven material that is overlapped so as to sandwich a part of the electric wire, it is possible to sufficiently suppress the sound from being transmitted to the inside of the vehicle. .

  According to the second invention, since at least a part of the outer edge portion of the planar member is joined, it is possible to prevent the planar member from being turned up.

  According to 3rd invention, at least one part of the part which pinches | interposes an electric wire among planar members is joined by hot press. For this reason, while being able to maintain the state where the planar member pinched the electric wire, positioning of the electric wire with respect to the planar member can also be performed.

  According to the fourth invention, the positioning member is formed in contact with or integrally with the planar member, supports the electric wire extending from the planar member, and is a recess provided in the arrangement target site. It can be fitted into the shape. Since the positioning member supports the electric wire and is fitted into the concave shape, the positioning member and the electric wire are positioned with respect to the arrangement target site. Further, the positioning member is formed in contact with or integrally with the planar member. For this reason, when the planar member is disposed at a certain position with respect to the arrangement target site, the state where the electric wire is disposed at the certain position with respect to the planar member is maintained. For this reason, it becomes possible to position an electric wire with respect to an arrangement | positioning object site | part and a planar member.

It is a top view which shows the state in which the wire harness 1 was attached. It is a top view of the wire harness 1b which concerns on the 2nd Embodiment of this invention. It is a top view of the wire harness 1c which concerns on the 3rd Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.

<1. First Embodiment>
The wire harness 1 according to the first embodiment shown in FIG. 1 is electrically connected between the electric wire devices by connecting both ends thereof to electric devices mounted on a vehicle such as an inverter and a motor. Have a role to play. The wire harness 1 includes, for example, an electric wire bundle 3 in which a plurality of electric wires 2 are bundled, and a planar member 4 made of a non-woven material that covers the periphery of the electric wire bundle 3.

  First, the wire bundle 3 will be described. As shown in FIG. 1, the electric wire bundle 3 has a structure in which a plurality of electric wires 2 are bundled. The electric wire 2 has a structure in which a core wire which is a linear conductor is covered with an insulating coating made of an insulator such as a resin. At both ends of the electric wire 2, connection terminals are attached to the bare core wires from which the insulation coating has been removed. When the connection terminal attached to the electric wire 2 is connected to each electrical equipment via a connector or the like, the wire harness 1 is connected to each electrical equipment. The form of the electric wire 2 used for the electric wire bundle 3 may be a circular cross section or a form such as a flat cable. Moreover, in this Embodiment, although it is the electric wire bundle 3 comprised by the some electric wire 2, the electric wire which comprises the wire harness 1 may be single. Further, another optical cable may be disposed along the electric wire 2.

  A planar member 4 made of a non-woven material is attached so as to sandwich a part of the electric wire bundle 3. The planar member 4 spreads in a planar shape in a region around the wire bundle 3 by being attached to a part of the wire bundle 3. A part of the wire bundle 3 is a middle portion in the extending direction of the wire bundle 3 excluding both ends of the wire bundle 3. Therefore, when the planar member 4 is attached to the electric wire bundle 3, both ends of the electric wire bundle 3 extend from the planar member 4 and are exposed to the outside. Here, as shown in FIG. 1, the wire bundle 3 is composed of three wires 2.

  The nonwoven material includes intertwined basic fibers and an adhesive resin called a binder. The adhesive resin is a resin having a melting point (for example, about 110 ° C. to 150 ° C.) lower than the melting point of the basic fiber. Such a nonwoven fabric is heated to a temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin, so that the adhesive resin melts and melts into the gaps of the basic fibers. Thereafter, when the temperature of the nonwoven material is lowered to a temperature lower than the temperature of the adhesive resin, the adhesive resin is cured in a state in which the basic fibers existing around are bonded. Thereby, the shape of a nonwoven material becomes harder than the state before a heating, and is maintained by the shape shape | molded by the mold at the time of a heating.

  The adhesive resin is, for example, a granular resin or a fibrous resin. It is also conceivable that the adhesive resin is formed so as to cover the periphery of the core fiber. As described above, the fiber having a structure in which the core fiber is coated with the adhesive resin is referred to as a binder fiber. As the material of the core fiber, for example, the same material as the basic fiber is adopted.

  Further, the basic fiber only needs to maintain the fiber state at the melting point of the adhesive resin, and various fibers can be adopted in addition to the resin fiber. Further, as the adhesive resin, for example, a thermoplastic resin having a melting point lower than the melting point of the basic fiber is employed. As a combination of the basic fiber constituting the nonwoven material and the adhesive resin, for example, a resin fiber mainly composed of PET (polyethylene terephthalate) is adopted as the basic fiber, and copolymerization of PET and PEI (polyethylene isophthalate). It is conceivable that a resin is employed as the adhesive resin. In such a nonwoven material, the melting point of the basic fiber is about 250 ° C., and the melting point of the adhesive resin is about 110 ° C. to 150 ° C. Such a nonwoven material is heated to a temperature of about 110 ° C. to 250 ° C. in the formwork, so that the adhesive resin melts and binds the surrounding basic fibers, and is molded into a shape along the inner surface of the formwork. Is done. Then, after being heated, the nonwoven material is cured while maintaining the molded shape.

  In the present embodiment, the electric wire bundle 3 is sandwiched between one piece of non-woven material having a folded rectangular surface region. That is, one side portion of the four sides constituting the outer edge portion of the planar member 4 is a folded portion of the nonwoven material. The planar member 4 may have a structure in which the electric wire bundle 3 is sandwiched between two nonwoven materials having a predetermined surface region from a direction orthogonal to the surface region.

  The four side portions constituting the outer edge portion of the planar member 4 are referred to as one side portions 40a, 40b, 40c, and 40d, respectively. The planar member 4 is a member in which the one side portion 40a and the one side portion 40c face each other, and the one side portion 40b and the one side portion 40d face each other. Further, the one side portion 40d corresponds to a folded portion of the nonwoven material. The wire bundle 3 covered with such a planar member 4 is branched into a T-shape in the planar member 4 here. In the electric wire bundle 3, a linear portion extends outward from the one side portions 40a and 40c, and a portion branched from the intermediate portion extends from the one side portion 40b toward the outside. However, the laying mode and branching mode of the wire bundle 3 may be arbitrarily set according to the laying layout of the wire bundle 3 at other locations, the installation position of the electrical equipment that is the connection destination, and the like. Among the outer edge portions of the planar member 4, one side portion 40 b is joined by hot pressing. It is not always necessary to join the nonwoven material by hot pressing. For example, the non-woven material may be joined by using an adhesive, or the non-woven material may be joined by sewing. In addition, it can be said that the part hot-pressed as mentioned above is at least a part of the outer edge part of the planar member 4, and can also be regarded as at least a part of a part sandwiching the electric wire 2.

  The portion subjected to the hot press at the one side portion 40b of the planar member 4 is joined in an overlapped state by the adhesive resin, and is compressed and has a dense structure as compared with the portion not subjected to the hot press. . In the case of FIG. 1, only one electric wire 2 is disposed toward the one side portion 40 b, and the periphery of the one side portion 40 b where the electric wire 2 is disposed is in a state where no heat pressing is performed. That is, the hot press is performed only on both ends of the one side portion 40b. For this reason, the circumference | surroundings of the one side part 40b in which the electric wire 2 was arrange | positioned have thickness compared with the planar member 4 of the adjacent hot-pressed part. In addition, it is not always necessary to avoid the position of the planar member 4 sandwiching the electric wire 2, and the hot pressing may be performed on the entire one side portion 40b. In the following, the hot-pressed portion of such a non-woven material is referred to as a hot press portion 41, and the portion that is not subjected to the hot press is referred to as a non-hot press portion 42. Since the non-hot press part 42 is not heated, it has a buffering property. Accordingly, the wire bundle 3 is protected from surrounding impacts such as vibration. Moreover, the non-hot press part 42 of the planar member 4 is in a state having a large number of fine spaces partitioned by basic fibers. For this reason, the non-thermal press part 42 also has soundproofing, and the wire bundle 3 with which the wire harness 1 is provided is surrounded by the member which has soundproofing. However, the hot press part 41 can also maintain a state having a large number of fine spaces partitioned by basic fibers depending on the degree of heating and compression. For this reason, the heat press part 41 can also be set as the structure which exhibits soundproofing.

  Next, the hot press process will be described. The hot press apparatus 8 which performs hot press on the planar member 4 has a structure as shown in FIG. 2 as an example. As described above, the hot press device 8 includes the lower mold unit 81 and the upper mold unit 85.

  The lower mold unit 81 includes a lower mold member 82 and a heater 83. The lower mold member 82 is a long member formed of a material such as a metal having excellent thermal conductivity. The lower mold member 82 has a protrusion 821 that protrudes upward and is formed along the longitudinal direction. Of the surfaces constituting the protrusion 821, the shape of the contact surface with the upper mold unit 85 is rectangular. As shown in FIG. 2, the heater 83 is embedded in the lower mold member 82.

  The upper mold unit 85 includes an upper mold member 86 and a heater 87. The upper mold member 86 has a structure in which the lower mold member 82 is inverted, and is a long member formed of a material such as a metal having excellent thermal conductivity, like the lower mold member 82. The upper mold member 86 has a protrusion 861 that protrudes downward and is formed along the longitudinal direction. Of the surfaces constituting the protrusion 861, the shape of the contact surface with the lower mold unit 81 is rectangular like the protrusion 821. The heater 87 is embedded in the upper mold member 86 as shown in FIG.

  The heaters 83 and 87 that heat the surfaces of the protrusions 821 and 861 that are in contact with the planar member 4 are not necessarily embedded in the upper mold member 86 and the lower mold member 82, and the protrusions 821 and 861 are not necessarily embedded. As long as heat transfer is possible, the heaters 83 and 87 may be installed in any manner.

  The protrusions 821 and the protrusions are arranged along the longitudinal direction of the upper mold member 86 and the lower mold member 82 included in the hot press device 8 and the direction of one side of the outer edge portion of the planar member 4 on which the hot pressing is performed. One side part where the hot pressing of the planar member 4 is performed is set between 861 and 861. The protrusions 821 and 861 heated by the heaters 83 and 87 sandwich one side of the planar member 4. As described above, the protrusions 821 and 861 are pressed against the planar member 4, whereby the hot press portion 41 is formed on the planar member 4.

  The nonwoven material sandwiched between the protrusions 821 and 861 is lower than the melting point of the basic fibers contained in the nonwoven material by the heaters 83 and 87, and is lower than the melting point of the adhesive resin contained in the nonwoven material. Heated to a high temperature. The heating temperature, the heating time, and the press pressure are appropriately set according to the hardness required for the hot press unit 41. In general, in the hot pressing process, the higher the heating temperature, the longer the heating time, and the higher the applied pressure, the harder the non-woven material is molded into a member having a high shape retention performance.

  A positioning member 5 is attached to the wire bundle 3 extending from the joined planar member 4. Thereby, the positioning member 5 supports a part of the wire bundle 3. Note that the wire bundle 3 may be sandwiched between the planar members 4 after the positioning member 5 is attached to the wire bundle 3. The positioning member 5 is made of a material harder than the non-hot press part 42. In FIG. 1, the positioning member 5 is attached to the electric wire 2 extending from one side 40 a and one side 40 c among the four sides constituting the outer edge of the planar member 4. In the present embodiment, the positioning member 5 has a structure in contact with the planar member 4. That is, the positioning member 5 is attached to the wire bundle 3 at a position where it comes into contact with the planar member 4 with the wire bundle 3 being sandwiched between the planar members 4. In this state, the positioning member 5 and the planar member 4 are continuously connected, and the electric wire 2 is not exposed between the positioning member 5 and the planar member 4.

  When the positioning member 5 is made of a resin material such as plastic, a mold corresponding to the desired shape of the positioning member 5 is produced, and injection molding is performed using the mold, thereby positioning member 5 5 is produced. The positioning member 5 may be formed in a single cylindrical shape, or may be formed in a cylindrical shape that can be divided vertically. In the former case, the electric wire 2 is preferably inserted into the formed positioning member 5 so that the electric wire 2 is supported by the positioning member 5. In the latter case, after the electric wire 2 is sandwiched in a state where the cylindrical positioning member 5 is divided vertically, the positioning member 5 divided vertically is combined to form a lock structure or an adhesive tape, etc. Therefore, it is preferable that the electric wire 2 is supported by the positioning member 5 by maintaining the united state.

  The positioning member 5 can also be obtained by hot pressing a nonwoven material. An example of the hot press apparatus 9 for producing the positioning member 5 made of such a nonwoven material is shown in FIG.

  The hot press device 9 includes a lower die unit 91 and an upper die unit 95, as with the hot press device 8. The lower mold unit 91 includes a lower mold member 92 and a heater 93. The lower mold member 92 is a long member made of a metal having excellent thermal conductivity. The upper part of the lower mold member 92 is formed in a groove shape that is open at both ends in the longitudinal direction, and its cross-sectional shape is rectangular. The lower mold member 92 is a mold that forms a lower portion when the positioning member 5 is hot-pressed.

  The upper mold unit 95 includes an upper mold member 96 and a heater 97. The upper mold member 96 is a long member made of a material such as metal having excellent thermal conductivity. The upper mold member 96 protrudes in a shape that fits into the groove-shaped portion of the lower mold member 92. That is, the upper mold member 96 is a mold that forms an upper portion when the positioning member 5 is hot-pressed.

  The heaters 93 and 97 are embedded in the upper mold member 96 and the lower mold member 92, respectively. The heaters 93 and 97 are heating devices that heat the nonwoven material to a temperature lower than the melting point of the basic fiber and higher than the melting point of the adhesive resin via the lower mold member 92 and the upper mold member 96. The heaters 93 and 97 are not necessarily embedded in the upper mold member 96 and the lower mold member 92. As long as heat can be transferred to the outer surfaces of the upper mold member 96 and the lower mold member 92, the heaters 93 and 97 may be installed in any manner.

  As shown in FIG. 3, the nonwoven material covers the electric wire 2 in a state of being bent in a U shape, and is fitted into the groove-shaped portion of the lower mold member 92. At this time, the end of the non-woven material is in contact with the planar member 4. Then, the upper die member 96 is fitted into the lower die member 92 so that the hot pressing is performed. The heating temperature, the heating time, and the pressing pressure are appropriately set according to the hardness required for the positioning member 5.

  When the positioning member 5 is formed by hot pressing a non-woven material as described above, the formation of the positioning member 5 and the attachment of the positioning member 5 to the wire bundle 3 are performed at once by hot pressing. Is possible. Therefore, it is possible to reduce the labor of the work.

  In addition, the positioning member 5 is not limited to the above-described embodiment, and the positioning member 5 is prepared in advance by hot pressing a non-woven material, and the electric wire 2 is disposed in the hollow portion of the manufactured positioning member 5 so that the positioning member 5 5 may be attached to the electric wire 2.

  Further, the positioning member 5 attached to the electric wire 2 is arranged along the slope of a three-dimensional member (for example, the center console 100) which is an installation space of the vehicle in which the electric wire bundle 3 is arranged. And the recessed part shape in which the positioning member 5 can be engage | inserted, for example, the groove part 200 is provided in the site | part of such arrangement | positioning object. When the positioning member 5 is fitted into the groove portion 200, the positions of the positioning member 5 and the electric wire 2 with respect to the vehicle are determined.

  FIG. 4 shows a state in which the wire harness 1 according to the present invention is installed below the vehicle, specifically below the driver's seat. The wire harness 1 is provided at a position sandwiched between the door portion 110 and the center console 100, and one side portion 40d faces the side where the brake pedal 120 and the accelerator pedal 130 are provided. The shape of the planar member 4 is formed according to the shape of the space of the vehicle to which the soundproofing material is attached (that is, it is formed so as to fit in a wide range as much as possible within the installation space). In FIG. 4, the hatched area of the planar member 4 represents the hot press portion 41. A positioning member 5 is attached to the electric wires 2 on the center console 100 side and the door portion 110 side, and the positioning member 5 is fitted in the groove portion 200. The electric wire 2 (electric wire bundle 3) extending from the positioning member 5 is disposed along the vehicle body and connected to other electrical equipment. Thus, after the wire harness 1 provided with the planar member 4 is disposed on the iron plate constituting the floor member, the floor carpet is laid on the wire harness 1 so that the floor portion of the passenger compartment is configured. Is done.

  As described above, the wire harness 1 according to the present embodiment has a structure in which the planar member 4 having a predetermined surface region sandwiches the wire bundle 3. Since the wire bundle 3 can be installed in the installation space of the vehicle with the sheet member 4 sandwiched between the planar members 4, the workability of the work of assembling the soundproofing material and the wire to the vehicle is improved. At the same time, the wire bundle 3 is sandwiched between non-heated non-woven materials having soundproofing properties, and the planar member made of this non-woven material covers the floor which is the installation target part, so that the interior of the vehicle It is possible to sufficiently suppress the transmission of sound.

  Further, the positioning member 5 attached to the electric wire 2 is fitted into the groove portion 200 provided in the arrangement target, whereby the positions of the positioning member 5 and the electric wire 2 with respect to the arrangement target site are determined. Thereby, the electric wire 2 can be positioned in a fixed position with respect to the floor which is an arrangement | positioning object site | part. In addition, since the positioning member 5 is in contact with the planar member 4 that sandwiches the electric wire 2, the electric wire 2 becomes the planar member 4 when the planar member 4 is disposed at a certain position on the floor that is an arrangement target site. In contrast, it is in a state of being disposed at a fixed position. For this reason, it becomes possible to position the electric wire 2 with respect to the floor and the planar member 4 which are arrangement | positioning object site | parts.

  Moreover, since the hot press part 41 by which at least one part of the outer edge part of the planar member 4 was hot-pressed is formed, the rolling up of the planar member 4 can be suppressed.

  And since the heat press part 41 is formed in at least one part of the part which pinches | interposes an electric wire, while the planar member can maintain the state which pinched | interposed the electric wire, it also positions the electric wire with respect to a planar member. Can do.

  Moreover, since the electric wire bundle 3 (electric wire 2) is sandwiched between the planar members made of the non-woven material 40, a space for separately routing the electric wire bundle 3 (electric wire 2) is not required, thus saving space. To contribute.

<2. Second Embodiment>
Next, the wire harness 1b according to the second embodiment will be described with reference to FIG. In the following embodiments, the same components as those shown in the first embodiment are denoted by the same reference numerals, and only differences from the wire harness 1 of the first embodiment will be described. It shall be.

  The configuration of the wire harness 1b shown in FIG. 5 is simplified compared to the wire harness 1, and the planar member 4 sandwiches the wire bundle 3 diagonally. The wire harness 1b in the second embodiment is different from the first embodiment in the position of the planar member 4 joined by hot pressing. Specifically, as shown in FIG. 5, the hot pressing is performed on the whole or a part of the planar member 4 where the wire bundle 3 is sandwiched. The hatched area of the planar member 4 shown in FIG. 5 represents the entire position of the planar member 4 where the wire bundle 3 is sandwiched. In addition, the part of the position where the wire bundle 3 is sandwiched in the planar member 4 is always the position on both sides of the planar member 4 with the wire bundle 3 in the center, and includes the case of only one hatched area. Absent.

  Since the position where the electric wire bundle 3 is sandwiched is joined by hot pressing, the movement of the electric wire bundle 3 is restricted, so that the positional deviation of the electric wire bundle 3 relative to the planar member 4 can be suppressed. In particular, the positional deviation of the wire bundle 3 toward the one side 40b or the one side 40d can be suppressed. Further, by joining the planar member 4, it is possible to maintain a state in which the planar member 4 sandwiches the wire bundle 3.

  Thus, the wire harness 1b according to the second embodiment can more reliably prevent the positional deviation of the wire bundle 3 with respect to the planar member 4. The state in which the planar member 4 sandwiches the wire bundle 3 can also be maintained.

  However, it is not essential to join the planar member 4 by hot pressing at a position where the wire bundle 3 is sandwiched. Even when the planar member 4 is joined by hot pressing at a position where the wire bundle 3 is sandwiched, a part of the planar member 4 that sandwiches the wire bundle 3 (as in the first embodiment) ( In the first embodiment, it may be hot-pressed at a portion (at the outer edge of the planar member 4).

<3. Third Embodiment>
Next, the structure of the wire harness 1c according to the third embodiment will be described with reference to FIG. In the following embodiments, the same constituent elements as those shown in the first embodiment and the second embodiment are denoted by the same reference numerals, and the first embodiment and the second embodiment. Only points different from the wire harnesses 1 and 1b of the embodiment will be described.

  The wire harness 1c according to the third embodiment has a structure in which the overlapped planar member 4 is connected by folding or joining at any position of the outer edge portion of the planar member 4. That is, when the planar member 4 is formed by folding one sheet of non-woven material, three sides (one side portions 40a, 40b, 40c) excluding the one side portion 40d that is the folded portion are hot-pressed. In addition, when the two planar members 4 are overlapped and joined, all four sides constituting the outer edge portion of the planar member 4 are joined by hot pressing. FIG. 6 shows a state in which the four sides constituting the outer edge portion are hot-pressed. You may perform a hot press one side part also including the position which pinches | interposes the electric wire 2 among the planar members 4. FIG.

  As described above, since the outer edge portion of the planar member 4 is joined to the wire harness 1c, the planar member 4 can be reliably prevented from turning up from the outer edge portion of the planar member 4. Moreover, since the position which pinches | interposes the electric wire bundle 3 of the outer edge part of the planar member 4 is joined by hot press, the position shift of the electric wire bundle 3 with respect to the planar member 4 can also be suppressed reliably.

  Thus, since the wire harness 1c according to the third embodiment can reliably prevent the planar member 4 from turning up, the state in which the planar member 4 sandwiches the wire bundle 3 is more reliably maintained. be able to. Further, the positional deviation of the wire bundle 3 with respect to the planar member 4 can also be reliably suppressed.

  But it is not essential that the outer edge part of the planar member 4 is joined by hot press. Further, even when the outer edge portion of the planar member 4 is joined by hot pressing, only a part of the outer edge portion of the planar member 4 is joined by hot pressing as in the first embodiment. It may be.

<4. Modification>
In addition, this invention is not limited to the said embodiment.

  The wire harness 1 according to the first embodiment may be in a form in which the positioning member 5 is not attached to the electric wire 2. In the wire harness 1b according to the second embodiment and the wire harness 1c according to the third embodiment, the positioning member 5 may not be attached to the electric wire 2. That is, the wire harness 1 may have a structure in which the planar member 4 made of a non-woven material sandwiches the electric wire 2.

  Moreover, in the said embodiment, although the positioning member 5 was a form which contact | connects the planar member 4, it is not restricted to such a form. The positioning member 5 and the planar member 4 may be integrally formed. For example, the non-woven material constituting the planar member 4 partially extends toward the end of the electric wire 2, and the extending non-woven material covers the periphery of the electric wire 2 to form the positioning member 5. It may be in the form. Further, the end of the positioning member 5 may be sandwiched between the overlapped planar members 4. As described above, the end portion of the positioning member 5 is sandwiched between the planar members 4. For example, the positioning member 5 is first attached to the wire bundle 3 at an interval narrower than the width of the planar member. The shaped member 4 is obtained by being attached so as to sandwich the end portion of the positioning member 5 and the wire bundle 3 between the positioning members 5. Furthermore, in this case, the planar member 4 may be hot pressed in a state where the end portion of the positioning member 5 is sandwiched between the planar members 4. Alternatively, the positioning member 5 may be joined to the planar member 4 with an adhesive or the like. As described above, when the planar member 4 and the positioning member 5 are integrally formed, the positional deviation of the wire bundle 3 can be more reliably suppressed.

  Moreover, in the said embodiment, although the structure where the wire harness 1 to which the planar member 4 was attached was provided under the driver's seat is shown, it is not restricted to such a form. The wire harness 1 can be disposed at any position as long as the soundproofing material of the vehicle is disposed.
