It is a top view which shows the modification of the wiring member which concerns on 1st Embodiment.

{First embodiment}
A wiring member according to the first embodiment will be described below. FIG. 1 is a plan view showing a wiring member 10 according to the first embodiment. FIG. 2 is a cross-sectional view cut along line II-II of FIG.

The wiring member 10 is a member that is connected to a component mounted on a vehicle and transmits electricity and/or light to and/or from the component. The wiring member 10 includes a sheet material 20 and a linear transmission member 30 fixed on the sheet material 20 . A plurality of linear transmission members 30 are fixed to the sheet material 20 here. Thereby, the plurality of linear transmission members 30 are positioned.

Materials constituting the sheet material 20 are not particularly limited, and include resins such as PVC (polyvinyl chloride), PE (polyethylene), PET (polyethylene terephthalate), PP (polypropylene), and PA (polyamide). or may contain a metal such as aluminum or copper. The structure of the sheet material 20 is not particularly limited, and may be a fibrous material having fibers such as a woven fabric, a knitted fabric, or a non-woven fabric, or a non-fibrous material having no fibers, such as a member formed by extrusion molding or injection molding. There may be. When the sheet material 20 is a non-fiber material made by extrusion molding, injection molding, or the like, it may be a foam material that has been foam-molded, or may be a solid material that is uniformly solid without being foam-molded.

Moreover, the sheet material 20 may have only one layer, or may have a plurality of layers. When the sheet material 20 has multiple layers, the material, structure, etc. of each layer can be appropriately set. For example, the sheet material 20 may be formed by stacking a resin layer and a resin layer, may be formed by stacking a resin layer and a metal layer, or may be a stack of a metal layer and a metal layer. It can be anything. Further, the sheet material 20 may be formed by stacking a non-fiber layer and a non-fiber layer, may be formed by stacking a non-fiber layer and a fiber layer, or may be formed by stacking a fiber layer and a fiber layer. A layer of material and a layer of fabric may be superimposed.

Also, here, the sheet material 20 is formed in a shape in which a portion where the linear transmission member 30 is not arranged is cut out, but this is not an essential configuration. The sheet material 20 may have other shapes such as a trapezoidal shape, a parallelogram shape, and a rectangular shape. Preferably, the sheet material 20 is formed in a shape corresponding to the path of the linear transmission member 30. As shown in FIG.

The linear transmission member 30 may be any linear member that transmits electricity, light, or the like. For example, the linear transmission member 30 may be a general electric wire having a core wire and a coating around the core wire, or may be a bare conductor wire, a shielded wire, an enameled wire, a nichrome wire, an optical fiber, or the like.

Various signal lines and various power lines may be used as the linear transmission member 30 for transmitting electricity. A linear transmission member 30 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.

It is conceivable that the linear transmission member 30 includes a transmission line body 32 that transmits electricity or light, and a coating 34 that covers the transmission line body 32 . For example, when the linear transmission member 30 is a general electric wire, the transmission line main body 32 corresponds to the core wire, and the coating 34 corresponds to the insulating coating. Such a core wire includes one or more strands. The wire is made of a conductive material such as copper, copper alloy, aluminum, aluminum alloy, or the like. When the core wire is composed of a plurality of strands, it is preferable that the plurality of strands are twisted. Also, the insulating coating is formed by extruding a resin material such as PVC or PE around the core wire.

Each end of the linear transmission member 30 is connected to a connector C in the example shown in FIG. Such connector C is connected to a mating connector provided on a component mounted on the vehicle, or a mating connector provided at the end of the linear transmission member 30 extending from the component mounted on the vehicle. However, the end of the linear transmission member 30 may be connected to a connection partner without the connector C interposed.

In the example shown in FIG. 1, five linear transmission members 30 are provided, but this is not an essential configuration. The number of linear transmission members 30 may be 1 to 4, or may be 6 or more. Hereinafter, when the five linear transmission members 30 need to be distinguished, they may be referred to as linear transmission members 30a, 30b, 30c, 30d, and 30e.

Further, in the example shown in FIG. 1, the linear transmission member 30 has its intermediate portion fixed on the sheet material 20 and its end portion extends outward from the sheet material 20, but this is not an essential configuration. . An end portion of the linear transmission member 30 may be positioned on the sheet material 20 .

Further, in the example shown in FIG. 1, the linear transmission members 30 extend parallel to each other on the sheet material 20, but this is not an essential configuration. For example, the linear transmission members 30 may cross each other. Further, in the example shown in FIG. 1, the linear transmission member 30 is bent on the sheet material 20 and disposed. Particularly in the example shown in FIG. 1, branches are formed. However, it is not essential that the branch is formed and that the linear transmission member 30 is bent, and the route of the linear transmission member 30 can be set as appropriate.

The sheet material 20 and the linear transmission member 30 are directly fixed at their contact portions. Here, the direct fixation of the contact portion means that the sheet material 20 and the linear transmission member 30 are directly adhered and fixed without an adhesive or the like provided separately. In the direct fixation of the contact portion, for example, resin contained in at least one of the sheet material 20 and the linear transmission member 30 is melted to stick and fix.

In forming such a state in which the contact portion is directly fixed, the resin may be melted, for example, by heat or melted by a solvent. That is, the state of direct fixation of the contact portion may be the state of direct fixation of the contact portion by heat or the state of direct fixation of the contact portion by solvent. Preferably, the contact portion is directly fixed by heat.

At this time, the means for forming the state of direct fixation of the contact portion is not particularly limited, and various means including known means such as welding, fusing and welding can be used. For example, when the contact portion is directly fixed by heat by welding, various welding means such as ultrasonic welding, heat-pressure welding, hot-air welding, and high-frequency welding can be employed. Further, when the contact portion directly fixed state is formed by these means, the sheet material 20 and the linear transmission member 30 are brought into the contact portion directly fixed state by the means. Specifically, for example, when the contact portion directly fixed state is formed by ultrasonic welding, the sheet material 20 and the linear transmission member 30 are brought into the contact portion directly fixed state by ultrasonic welding. A portion (fixed portion between the sheet material 20 and the linear transmission member 30) in which a contact portion directly fixed by heat is formed by welding is called a welded portion, and a portion fixed by ultrasonic welding is an ultrasonic welded portion. A portion fixed by pressure welding may be referred to as a heat-pressure welded portion or the like.

In directly fixing the contact portion, only the resin contained in the sheet material 20 may be melted, or only the resin contained in the linear transmission member 30 may be melted. In these cases, the melted resin may become stuck to the outer surface of the other, forming a relatively sharp interface. In addition, both the resin contained in the sheet material 20 and the resin contained in the linear transmission member 30 may be melted in the direct fixation of the contact portion. In this case, both resins may mix and a clear interface may not be formed. In particular, when the sheet material 20 and the coating 34 of the linear transmission member 30 contain resins that are easily compatible, such as the same resin material, both resins may mix and a clear interface may not be formed.

For example, when the sheet material 20 and the linear transmission member 30 are fixed by ultrasonic welding, the sheet material 20 and the linear transmission member 30 are sandwiched between the horn H and the anvil A of the ultrasonic welding machine. It is conceivable to apply ultrasonic vibration by As a result, at least one of the sheet material 20 and the linear transmission member 30 melts due to the frictional heat generated at the interface between the sheet material 20 and the linear transmission member 30, and the sheet material 20 and the linear transmission member 30 are separated. is fixed. At this time, the example shown in FIG. 2 shows how the sheet material 20 and the linear transmission member 30 are sandwiched between the horn H and the anvil A of the ultrasonic welding machine and ultrasonically welded.

When the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions, the linear transmission member 30 is directly fixed at the contact portions to the sheet material 20 at three or more locations spaced apart in the longitudinal direction thereof. ing. Below, each contact portion directly fixed portion between each sheet material 20 and the linear transmission member 30 may be referred to as a spot fixing portion. For one linear transmission member 30, one spot fixing portion may be formed in sequence, or a plurality of spot fixing portions 50 may be formed at once.

In each drawing, reference numeral 50 indicates a position where a spot fixing portion is formed. In the following, this reference numeral 50 is assigned to the spot fixing portion and will be described as the spot fixing portion 50 . Here, in each drawing, the spot fixing portion 50 has a circular shape for the sake of convenience, but the shape of the spot fixing portion 50 is not limited to a circular shape. Further, in each drawing, for convenience, the spot fixing portions 50 are formed to have the same size (range), but the spot fixing portions 50 having different sizes (ranges) may be formed.

The distance between two contact portion direct fixing points (spot fixing portions 50) that are continuous in the longitudinal direction of the linear transmission member 30 among the contact portion directly fixing points (spot fixing portions 50) between the sheet material 20 and the linear transmission member 30 be a fixed interval D.

The wiring member 10 has portions with different fixed intervals D. As shown in FIG. Of the portions with different fixing intervals D, the portions with narrow fixing intervals D are portions where the fixing strength between the sheet material 20 and the linear transmission member 30 is desired to be increased. Of the portions with different fixing intervals D, the portion with the wide fixing interval D is a portion that does not require high fixing strength between the sheet material 20 and the linear transmission member 30 . By widening the fixing interval D, the number of spot fixing portions 50 is reduced, and the time required for manufacturing can be shortened.

Here, it is assumed that the fixing strength of each spot fixing portion 50 is the same. Therefore, the fixing strength between the sheet material 20 and the linear transmission member 30 mainly depends on the fixing interval D of the spot fixing portions 50 . However, spot fixing portions 50 having different fixing strengths may be formed. In particular, the fixing strength of the spot fixing portion 50 in a portion where high fixing strength is required, such as a portion with a narrow fixing interval D, is higher than the fixing strength of the spot fixing portion 50 in a portion where high fixing strength is not required, such as a portion with a wide fixing interval D. It is also conceivable that it is set higher than In order to increase the fixing strength of the spot fixing portion 50, the energy given when forming the spot fixing portion 50 can be increased by, for example, increasing the energy given per unit time or lengthening the time for which the energy is given. It is conceivable to make it larger.

Here, there is a portion where the fixed interval D is different between the terminal side portion 36 and the intermediate side portion 38 of the linear transmission member 30 . Specifically, the portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion of the terminal side portion 36 of the linear transmission member 30 at a distance wider than the fixed interval D1 is located closer to the terminal side portion 36 than the terminal side portion 36 . It resides in the medial side portion 38 .

As the fixed interval D1 of the terminal-side portion 36 to be compared, the fixed interval D located closest to the terminal side will be described. However, as the fixed interval D1 of the terminal side portion 36, the average value of the fixed interval D located closest to the terminal side and the adjacent fixed interval D may be considered, or the fixed interval D located closest to the terminal side may be used. and the fixed interval D next to it.

As the fixed interval D2 of the intermediate portion 38 to be compared, the maximum value among at least one fixed interval D2 in the intermediate portion 38 will be described.

The terminal-side portion 36 to be compared may be either the one terminal-side portion 36 or the other terminal-side portion 36. For example, it is conceivable that the fixed interval D is smaller. In other words, the portion where the sheet material 20 and the linear transmission member 30 are directly fixed to the contact portion at a distance wider than the fixing interval D1 in either of the terminal side portions 36 exists in the intermediate side portion 38 rather than the terminal side portion 36. It's fine if you do. Of course, there is a portion in which the sheet material 20 and the linear transmission member 30 are directly fixed to the contact portions at a distance wider than the fixing interval D1 in the both terminal side portions 36, in the middle side portion 38 rather than the terminal side portion 36. There may be.

More specifically, in the example shown in FIG. 1, both terminal side portions 36 of the linear transmission member 30a are formed with the same fixed interval D1. At this time, in the linear transmission member 30a, the fixed interval D2 at the intermediate side portion 38 is wider than the fixed interval D1 at the both terminal side portions 36. As shown in FIG. The same applies to the linear transmission members 30b, 30c, 30d and 30e.

The wiring member 10 is provided with a parallel assembly portion 12 and a spaced assembly portion 14 . The parallel assembly portion 12 and the spaced assembly portion 14 are portions that are assembled in different states when the wiring member 10 is assembled to the vehicle. The parallel assembly portion 12 and the spaced assembly portion 14 are provided continuously.

More specifically, the parallel assembly portion 12 is a portion that is assembled parallel to the peripheral member 80 when the wiring member 10 is assembled to the vehicle. On the other hand, the spaced mounting portion 14 is a portion that is mounted away from the peripheral member 80 when the wiring member 10 is mounted on the vehicle. The example shown in FIG. 1 is an example in which reinforcement is employed as the peripheral member 80 . The peripheral member 80 may be various panels, trims, pillars, etc. in addition to reinforcement. Note that the parallel assembly portion 12 may or may not be fixed to the peripheral member 80 . When the parallel assembly portion 12 is fixed to the peripheral member 80, the peripheral member 80 can be regarded as a member to be fixed.

Here, there is a portion where the fixing distance D differs between the parallel assembly portion 12 and the spaced assembly portion 14 . Specifically, there is a portion in the parallel assembly portion 12 where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion at a distance wider than the fixed interval D3 in the separate assembly portion 14 .

As the fixed interval D3 of the separated assembly portion 14 to be compared, the smallest fixed interval D in the separated assembly portion 14 will be described. However, as the fixed interval D3 of the separated assembly portion 14 to be compared, an average value of a plurality of fixed intervals D of the separated assembly portion 14 may be used.

As the fixed interval D4 of the parallel assembled portion 12 to be compared, the maximum value among at least one fixed interval D in the parallel assembled portion 12 will be described.

When there are a plurality of spaced assembling portions 14, the portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion with a spacing wider than the fixed space D3 in some of the spaced assembling portions 14 is parallel. It suffices if it exists in the assembly section 12 . It is preferable that the parallel assembly portion 12 has a portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions at intervals wider than the fixed interval D3 in all the separated assembly portions 14. .

More specifically, in the example shown in FIG. 1, the portion of the wiring member 10 that includes the end portions of the linear transmission members 30 is the spaced assembly portion 14, and the portion therebetween is the parallel assembly portion 12. . A fixed interval D3 in each spaced mounting portion 14 is formed in the same manner. At this time, in the linear transmission members 30a, 30b, 30c, 30d, and 30e, the fixing interval D4 in the parallel assembly portion 12 is wider than the fixing interval D3 in the spaced assembly portion 14. FIG.

The linear transmission member 30 has a bent portion 40 bent on the sheet material 20 .

Here, there is a portion apart from the curved portion 40 where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion at a distance wider than the fixed interval D5 at the curved portion 40 . The linear transmission member 30 has a linear portion 42 that extends linearly on the sheet material 20 . Here, there is a portion in the straight portion 42 where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion at a distance wider than the fixed distance D5 in the curved portion 40 .

Here, the fixing interval D5 in the curved portion 40 refers to the interval between two spot fixing portions 50 between which the curved portion 40 exists. For example, when the curved portion 40 has the spot fixing portion 50 , the space between the spot fixing portion 50 positioned on the curved portion 40 and the spot fixing portion 50 that is continuous therewith can be the fixed interval D5 in the curved portion 40 . In this case, there are a plurality of fixed intervals D in the curved portion 40 . Specifically, for example, in the linear transmission member 30 a , the curved portion 40 is formed at the portion from the parallel assembly portion 12 toward the spaced assembly portion 14 . At this time, one spot fixing portion 50 exists in the curved portion 40 . Therefore, the interval between the spot fixing portion 50 and the spot fixing portions 50 continuing on both sides can be the fixing interval D5 in the curved portion 40 . Further, for example, when the spot fixing portion 50 does not exist in the curved portion 40, the interval between the two spot fixing portions 50 formed at the position closest to the curved portion 40 and sandwiching the curved portion 40 is the curved portion 40. is a fixed interval D5 in . In this case, there is only one fixed spacing D5 in that bend 40 . Specifically, for example, in the linear transmission member 30 d , the curved portion 40 is formed in a portion extending from the parallel assembly portion 12 toward the spaced assembly portion 14 . At this time, the spot fixing portion 50 does not exist in the curved portion 40 of the linear transmission member 30d. Therefore, in the linear transmission member 30d, the interval between the two spot fixing portions 50 between which the curved portion 40 exists is the fixed interval D5 of the curved portion 40. As shown in FIG.

As the fixed interval D5 of the curved portion 40 to be compared, the smallest fixed interval D in the curved portion 40 will be described. However, as the fixed interval D5 of the curved portion 40 to be compared, an average value of a plurality of fixed intervals D5 of the curved portion 40 may be used.

As the fixed interval D6 of the straight portion 42 to be compared, the maximum value among at least one fixed interval D in the straight portion 42 will be described.

More specifically, in the example shown in FIG. 1, in the linear transmission member 30a, the fixed interval D6 at the straight portion 42 is wider than the fixed interval D5 at the curved portion 40. As shown in FIG. The same applies to the linear transmission members 30b, 30c, 30d and 30e.

When there are a plurality of curved portions 40, the straight portion 42 has a portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions at intervals wider than the fixed interval D5 in some of the curved portions 40. It's fine if you do. It is preferable that the linear portion 42 has a portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions at intervals wider than the fixed interval D5 in all the curved portions 40 .

In the example shown in FIG. 1, in the wiring member 10, the spot fixing portions 50 are formed at positions adjacent to the plurality of linear transmission members 30 extending in parallel. Such a wiring member 10 is formed, for example, by collectively fixing a plurality of linear transmission members 30 extending in parallel when forming one spot fixing portion 50 . For example, in the example shown in FIG. 2, ultrasonic vibration is applied to the sheet material 20 and the plurality of linear transmission members 30 sandwiched between the horn H and the anvil A, thereby forming a plurality of linear transmission members extending in parallel. A state in which the spot fixing portions 50 are collectively formed at adjacent positions of the transmission member 30 is shown.

According to the wiring member 10 configured as described above, in the wiring member 10 in which the sheet material 20 and the linear transmission member 30 are directly fixed to the contact portions with a space therebetween, portions with different fixing intervals D are formed. there is For this reason, by shortening the fixing interval D in a portion requiring high fixing strength and lengthening the fixing interval D in a portion not requiring high fixing strength, suitable fixing strength can be easily obtained at each portion.

Here, when the sheet material and the linear transmission member are wholly welded in one heating and pressurizing step, it is difficult to control the partially fixed state. Specifically, when a wiring member has a portion that requires high fixing strength and a portion that does not require high fixing strength, the conditions are set according to the portion that requires high fixing strength, and heat and pressure are applied. Welding may result in excessive quality in areas where high fixing strength is not required. In addition, if the conditions are not properly set, uneven fixing may occur, and sufficient fixing strength may not be obtained in areas where high fixing strength is required.

On the other hand, in the wiring member 10, since the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions with a space therebetween, the fixing at each portion is more difficult than in the case where the contact portions are directly fixed as a whole. Easy to control state. Specifically, since the spot fixing portions 50 are formed in a narrower range than in the case where the contact portion is directly fixed as a whole, it is easy to set conditions for one spot fixing portion 50, and fixation unevenness is less likely to occur. This makes it easier to obtain a suitable fixing strength for each part.

Further, since the linear transmission member 30 is connected when the wiring member 10 is assembled, the terminal side portion 36 is more often gripped or moved than the intermediate side portion 38 . In this manner, the fixing interval D1 of the terminal side portion 36, which is often handled frequently and requires a large force during handling, is relatively narrowed after the wiring member 10 is manufactured and before it is assembled to the vehicle. Therefore, at the terminal side portion 36, the linear transmission member 30 is less likely to peel off from the sheet material 20 during assembly.

In addition, since the separated assembly portion 14 is separated from the peripheral member 80 , it is more susceptible to vibration than the parallel assembly portion 12 . Even in this case, in the wiring member 10, since the fixing interval D3 is relatively narrow at the separate assembly portion 14, the linear transmission member 30 at the separate assembly portion 14 is less likely to peel off from the sheet material 20. FIG.

In addition, the linear transmission member 30 is likely to loosen at the curved portion 40 , and the linear transmission member 30 may be lifted from the sheet material 20 due to the loosening. Even in this case, in the wiring member 10 , since the fixing interval D5 is relatively narrow at the curved portion 40 , the curved portion 40 of the linear transmission member 30 can be prevented from floating from the sheet material 20 .

{Second embodiment}
A wiring member according to the second embodiment will be described. FIG. 3 is a side view showing the wiring member 110 according to the second embodiment. 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 wiring member 110 is provided with a curved assembly portion 16 and a straight assembly portion 18 . The curved assembly portion 16 and the straight assembly portion 18 are parts that are assembled in different states when the wiring member 110 is assembled to the vehicle. The curved assembly portion 16 and the straight assembly portion 18 are continuously provided.

More specifically, the bent assembly portion 16 is such that the longitudinal portion of the linear transmission member 30 is bent in the front and back directions of the sheet material 20 while the wiring member 110 is assembled to the vehicle. It is a part that can be assembled in a closed state.

The linear assembly portion 18 is a portion to which a longitudinal portion of the linear transmission member 30 is linearly assembled when the wiring member 110 is assembled to the vehicle. The straight assembly portion 18 is a portion other than the curved assembly portion 16, that is, the portion of the linear transmission member 30 along the longitudinal direction in the state that the wiring member 110 is assembled to the vehicle. It can also be said that it is a part that is assembled so as not to cause bending in the opposite direction.

In the example shown in FIG. 4, the wiring member 110 is assembled along the peripheral member 180 to produce the curved assembly portion 16 and the straight assembly portion 18 . Specifically, a step 182 is formed on the peripheral member 180 . The wiring member 110 is attached to the peripheral member 180 in such a manner that the longitudinal portion of the linear transmission member 30 climbs over the step 182 . As a result, the portion of the wiring member 110 that goes over the step 182 becomes the curved assembly portion 16 , and the portion extending away from the step 182 , that is, the portion before or after going over the step 182 becomes the straight assembly portion 18 .

Of course, it is conceivable that the wiring member 110 may have the curved assembly portion 16 and the straight assembly portion 18 other than the above. For example, while the wiring member 110 is bent, a path regulating member is attached to the bent portion, or two portions along the longitudinal direction of the wiring member 110 are fixed to different counterparts and the portion between them is bent. Also, curved joins 16 and straight joins 18 can occur.

It is preferable that the linear transmission member 30 extends linearly on the sheet material 20 before assembly in the curved assembly portion 16 and the straight assembly portion 18 . In other words, the portion where the linear transmission member 30 is linearly arranged on the flat sheet material 20 is assembled in a state of being bent in the front and back directions of the sheet material 20, and the curved assembly portion 16 and the A linear assembly portion 18 is preferred. Of course, the portion where the linear transmission member 30 is bent with respect to the flat sheet material 20 is assembled in a state of being bent in the front and back directions of the sheet material 20, and the curved assembly portion 16 and the straight assembly are assembled. It may be an attached portion 18 .

Here, there is a portion where the fixed interval D differs between the curved assembly portion 16 and the straight assembly portion 18 . Specifically, there is a portion in the linear assembly portion 18 where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions at intervals wider than the fixed interval D7 in the curved assembly portion 16 .

Here, the fixing interval D7 in the curved assembling portion 16 means the interval between two spot fixing portions 50 between which the curved assembling portion 16 exists. For example, when there is a spot fixing portion 50 in the curved assembly portion 16, the space between the spot fixing portion 50 located in the curved assembly portion 16 and the spot fixing portion 50 continuous with it is the fixed portion in the curved assembly portion 16. It can be the interval D7. In this case, there are a plurality of fixed intervals D in the curved assembly portion 16 . Specifically, for example, in the linear transmission member 30 f , the portion that gets over the step 182 is the curved assembly portion 16 . At this time, one spot fixing portion 50 exists in the song assembling portion 16 . Therefore, the interval between the spot fixing portion 50 and the spot fixing portions 50 continuing on both sides can be the fixed interval D7 in the curved assembling portion 16 . Further, for example, when the spot fixing portion 50 does not exist in the curved assembly portion 16, two spot fixing portions 50 formed at positions closest to the curved assembly portion 16 and sandwiching the curved assembly portion 16 are provided. is the fixed interval D7 in the curved assembly portion 16. As shown in FIG. In this case, there is only one fixed spacing D7 in that bend 40. FIG.

As the fixed interval D7 of the curved assembly portion 16 to be compared, the smallest fixed interval D in the curved assembly portion 16 will be described. However, as the fixed interval D7 of the curved assembly portion 16 to be compared, an average value of a plurality of fixed intervals D in the curved assembly portion 16 may be used.

As the fixed interval D8 of the linear assembly portion 18 to be compared, the maximum value of at least one fixed interval D in the linear assembly portion 18 will be described.

More specifically, in the example shown in FIG. 3, in the linear transmission member 30f, the fixing interval D8 at the linear assembly portion 18 is wider than the fixing interval D7 at the curved assembly portion 16. As shown in FIG.

When there are a plurality of curved assembling portions 16, the portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portion with a spacing wider than the fixed interval D7 in some of the curved assembling portions 16 is a straight line. It suffices if it exists in the assembly section 18 . It is preferable that the straight assembly portion 18 has a portion where the sheet material 20 and the linear transmission member 30 are directly fixed at the contact portions at intervals wider than the fixed interval D7 in all the curved assembly portions 16. .

In the curved assembly portion 16 , the longitudinal portion of the linear transmission member 30 is bent in the front and back directions of the sheet material 20 , so the linear transmission member 30 is easily lifted from the sheet material 20 . Even in this case, according to the wiring member 110, since the fixing interval D7 is relatively narrow at the curved assembly portion 16, it is possible to prevent the linear transmission member 30 from floating from the sheet material 20 at the curved assembly portion 16. .

{Modification}
FIG. 4 is a plan view showing a modification of the wiring member 10 according to the first embodiment.

Although the description has been made assuming that the spot fixing portions 50 are formed at adjacent positions of the plurality of linear transmission members 30 extending in parallel, this is not an essential configuration. The position where the spot fixing portion 50 is formed may be set for each linear transmission member 30 . For example, the spot fixing portion 50 is formed for each linear transmission member 30 by applying ultrasonic vibrations while the sheet material 20 and one linear transmission member 30 are sandwiched between the horn H and the anvil A. position can be set. When the spot fixing portions 50 are appropriately formed for each of the linear transmission members 30 in this way, the spot fixing portions 50 are placed at different positions with respect to the linear transmission members 30 extending parallel to each other, as in the wiring member 10A shown in FIG. can be formed.

Specifically, in the example shown in FIG. 4, the spot fixing portions 50 are formed at different positions with respect to the linear transmission member 30 extending parallel to the curved portion 40 and the straight portion 42 . In the example shown in FIG. 4, it can also be understood that the spot fixing portions 50 are formed at different positions with respect to the linear transmission member 30 extending parallel to the branch portion 19 .

In the first embodiment, the difference between the fixed interval D1 of the terminal side portion 36 and the fixed interval D2 of the intermediate side portion 38, the difference between the fixed interval D3 of the parallel assembly portion 12 and the fixed interval D4 of the separated assembly portion 14, Also, the difference between the fixed interval D5 of the curved portion 40 and the fixed interval D6 of the straight portion 42 coexisted, but one or two of them may be omitted. Further, the difference between the fixed interval D7 of the curved assembly portion 16 and the fixed interval D8 of the straight assembly portion 18 in the second embodiment is the difference between the three fixed intervals in the first embodiment (difference between D1 and D2). , the difference between D3 and D4 or the difference between D5 and D6).

Further, in the example described so far, the plurality of linear transmission members 30 have the same diameter, but one wiring member 10 may include linear transmission members 30 having different diameters.

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

The following aspects are disclosed in the specification and drawings.
A wiring member according to a first aspect includes a sheet material, and a linear transmission that extends on the sheet material and is directly fixed to the sheet material at three or more locations spaced apart in the longitudinal direction of the sheet material. wherein the space between two contact portion directly fixed portions that are continuous in the longitudinal direction of the linear transmission member among the contact portion directly fixed portions between the sheet material and the linear transmission member is defined as a fixed interval. , there are portions where the fixed intervals are different.
A wiring member according to a second aspect is the wiring member according to the first aspect, in which the sheet member and the linear transmission member are separated from each other at an interval wider than the fixed interval at the terminal side portion of the linear transmission member. A portion where is directly fixed to the contact portion exists in the intermediate side portion from the terminal side portion.
A wiring member according to a third aspect is the wiring member according to the first or second aspect, and includes a parallel assembly portion that is assembled in parallel with the peripheral member when assembled to the vehicle; A spaced assembly portion is provided so as to be assembled away from the peripheral member, and the sheet material and the linear transmission member are directly fixed at the contact portion at a space wider than the fixed space in the spaced assembly portion. A portion is present in the parallel assembly portion.
A wiring member according to a fourth aspect is the wiring member according to any one of the first to third aspects, wherein the linear transmission member has a curved portion that is bent on the sheet material, A portion where the sheet member and the linear transmission member are directly fixed at the contact portion at a distance wider than the fixing interval at the curved portion exists at a portion away from the curved portion.
A wiring member according to a fifth aspect is the wiring member according to any one of the first to fourth aspects, wherein the linear transmission member extends along the longitudinal direction in a state of being assembled to the vehicle. A curved assembling section in which a portion is bent in the front and back directions of the sheet material, and a straight assembling section in which a portion along the longitudinal direction of the linear transmission member is linearly assembled. is provided, and a portion in which the sheet material and the linear transmission member are directly fixed at the contact portion at a wider interval than the fixed interval in the curved assembly portion is present in the linear assembly portion.
According to each aspect, in the wiring member in which the sheet material and the linear transmission member are directly fixed at the contact portion with a space therebetween, portions with different fixed intervals are formed. For this reason, by shortening the fixing interval in portions requiring high fixing strength and lengthening the fixing interval in portions not requiring high fixing strength, it becomes easier to obtain suitable fixing strength in each portion.
Since the linear transmission member is connected when the wiring member is assembled, the terminal side portion is more often gripped or moved than the intermediate side portion. Even in this case, according to the second aspect, since the interval for directly fixing the contact portion between the sheet material and the linear transmission member at the terminal side portion is narrow, the linear transmission at the terminal side portion can be prevented during assembly or the like. The member becomes difficult to peel off from the sheet material.
A spaced assembly is more susceptible to vibration than a parallel assembly. Even in this case, according to the third aspect, the linear transmission member is less likely to peel off from the sheet material at the spaced assembly portion.
According to the fourth aspect, it is possible to suppress floating of the curved portion of the linear transmission member from the sheet material.
According to the fifth aspect, it is possible to prevent the linear transmission member from floating from the sheet material at the curved assembly portion.
Although the present invention has been described in detail as above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that numerous variations not illustrated can be envisioned without departing from the scope of the invention.
