{First embodiment}
Hereinafter, the wire harness with a guide body according to the first embodiment will be described. FIG. 1 is a perspective view showing a wire harness 10 with a guide body according to the first embodiment, and FIGS. 2 and 3 are explanatory views showing an example of use of the wire harness 10 with a guide body.

  This wire harness 10 with a guide body is arrange | positioned between two members, and is used as wiring which electrically connects between the two members. The two members are generally in the relationship of the attached member 50 and the attaching member 60 attached to the attached member 50. An example of the attached member 50 is an instrument panel or the like. An example of the attachment member is a meter unit having a speedometer, a seat slide switch, a headlamp switch, a level switch for adjusting the optical axis of the headlight, and the like. In attaching these attachment members 60 to the attachment member 50, generally, after connecting the wiring to the attachment member 60 and the attachment member 50 at a position slightly away from the attachment member 60, the attachment member 60 is attached to the attachment member 60. The operation of attaching to the member to be attached 50 is performed. For this reason, in the state which attached the attachment member 60 to the to-be-attached member 50, the extra length arises in the said wiring material. Therefore, it is necessary to absorb the extra length of such wiring. This wire harness 10 with a guide body is used as a wiring material which can absorb such extra length.

  The guide-attached wire harness 10 includes a pair of non-woven members 20 and a wire harness 30.

  The non-woven member 20 is zigzag folded at a plurality of folds 22. More specifically, the non-woven member 20 is formed into a long band shape by hot pressing as described later, and a plurality of folds 22 are spaced along the longitudinal direction thereof. (Here, evenly spaced). Each fold 22 is formed so as to cross the non-woven member 20 in its width direction. The folds 22 are alternately folded in the opposite direction in the longitudinal direction of the non-woven member 20. A more specific processing example of the non-woven member 20 will be described later.

  The wire harness 30 has at least one electric wire 32. Here, the wire harness 30 has a plurality of electric wires 32 and is divided into two groups. The group 31 of one wire harness 30 is accommodated in the one nonwoven member 20 in a state along the longitudinal direction of the one nonwoven member 20. The group 31 of the other wire harness 30 is accommodated in the other nonwoven member 20 in a state along the longitudinal direction of the other nonwoven member 20. Here, the non-woven member 20 is hot-pressed in a state in which the electric wire 32 is disposed in the non-woven member 20, whereby the electric wire 32 is accommodated and held therein. A specific example of this method will be described later.

  But it is not essential that the wire harness 30 has the some electric wire 32, and what is necessary is just to have at least one electric wire 32. FIG. Moreover, the electric wire 32 does not need to be a thing with a circular cross section, For example, you may use the flat electric wire etc. which pinched | interposed the several core wire arrange | positioned in parallel with a pair of insulating film as an electric wire.

  Moreover, it is not essential that the electric wires 32 are accommodated in both of the pair of non-woven members 20, and the electric wires 32 may be accommodated only in one non-woven member 20. Further, it is not essential that the electric wire 32 is accommodated in the non-woven member 20, and the electric wire 32 may be laid on the outer surface of the non-woven member 20, or may be configured by a pair of non-woven members 20. The electric wire 32 may be attached to any part of the guide body 26 and the electric wire 32 may be supported along the guide body 26.

  Further, the pair of non-woven members 20 are combined so as to form a continuous rhombus frame, thereby forming a guide body 26 that can be expanded and contracted by changing the folding angle of each fold 22. Yes. In other words, the pair of non-woven members 20 are combined so as to form a kind of panda graph structure.

  More specifically, the electric wire 32 is accommodated in one side portion of the non-woven member 20, and the slit 24 is formed between the folds 22 of the non-woven member 20. The slit 24 is formed so as to go from the other side of the non-woven member 20 to one side along the width direction of the non-woven member 20. The slit 24 is formed on the other side of the non-woven member 20 with respect to the housing portion of the electric wire 32, and preferably has a length about half the width of the non-woven member 20.

  The pair of non-woven members 20 are formed by continuously fitting a plurality of rhombuses having apexes of two fitting portions of adjacent slits 24 and two opposing folds 22 by fitting the slits 24 together. It is formed. The guide body 26 is configured by combining the pair of non-woven members 20 in this way.

  The wire harness 10 with a guide body configured in this way is used as follows. That is, when attaching the attachment member 60 such as a meter unit to the attachment member 50 such as an instrument panel in the vehicle, one end of the wire harness with guide body 10 is connected to the electric device or wiring on the attachment member 50 side. The The connection here is made by connector connection or the like. But the wire harness 10 with a guide body is integrated as a part of the wire harness routed in the to-be-attached member 50, and the part corresponded to the wire harness 10 with a guide body is pulled out from the to-be-attached member 50 outside. May be.

  And the other end part of the wire harness 10 with a guide body is connected to the to-be-attached member 50 by a connector connection. Under the present circumstances, the length dimension of the wire harness 30 of the wire harness 10 with a guide body is set so that it may be longer than the length required for original wiring, ie, an extra length may arise. And in the state before attaching the attachment member 60 to the to-be-attached member 50, the wire harness 10 with a guide body can be expand | extended by enlarging the folding angle of the crease | fold 22 (refer FIG. 2). Thereby, the wire harness 10 with a guide body is pulled out from the attached member 50, and the connection work of the wire harness 10 with a guide body 10 and the attachment member 60 is performed in a state in which the handling performance of the wire harness 10 with a guide body is improved. Easy to do.

  On the other hand, when the attached member 50 is brought close to the attaching member 60, the wire harness with guide body 10 can be deformed by reducing the folding angle of the fold line 22. At this time, the guide body 26 has a kind of pantograph structure, and can be reduced and deformed while maintaining a rhombus, that is, maintaining a linear state (see FIG. 3). For this reason, the guide body 26 can maintain a linear state in a contracted state, and hardly hangs down in a U shape between the attached member 50 and the attaching member 60. Thereby, between the to-be-attached member 50 and the attachment member 60, the wire harness 10 with a guide body is maintained in the state which is hard to interfere with a surrounding member.

  With reference to FIGS. 4-8, the example of a manufacturing method of the said wire harness 10 with a guide body is demonstrated.

  First, a rectangular sheet-like nonwoven material 20a is prepared, and a group 31 of wire harnesses 30 is disposed on one main surface of the nonwoven material 20a (see FIG. 4).

  Here, as the nonwoven material 20a, a material in which main fibers and binder fibers are entangled with each other can be used. The main fiber is formed in a fiber shape and has a higher melting point than the binder described below. The binder fiber is formed, for example, by forming a binder layer on the outer periphery of the core fiber, and has a fiber shape as a whole. The melting point of the core fiber is higher than the melting point of the binder. That is, the binder is a resin having a lower melting point than the main fiber and the core fiber. Then, by heating the nonwoven material to a temperature lower than the melting point of the main fiber and the core fiber and higher than the melting point of the binder, the binder melts and penetrates between the main fiber and the core fiber. Thereafter, when the nonwoven material 20a becomes a temperature lower than the melting point of the binder, the binder is solidified in a state where the main fibers and the core fibers are bonded to each other. Thereby, a nonwoven material becomes harder than the state before a heating, and comes to be maintained in the shaping | molding shape at the time of a heating. Moreover, in the part which the nonwoven material 20a was mutually contacting, the nonwoven material 20a is joined by the binder solidified after melting.

  The main fiber only needs to maintain the fiber state at the melting point of the binder, and as the main fiber, various fibers can be used in addition to the resin fiber. Further, in the present embodiment, description will be made assuming that the main fiber and the core fiber are made of the same material, but these need only have melting points higher than the binder, and need not necessarily be made of the same material. Absent.

  Moreover, the binder does not necessarily need to be present in the form formed on the outer periphery of the core fiber as described above. It suffices that the binder itself is formed in a granular shape or a fiber shape and is mixed in the main fiber.

  Next, the nonwoven material 20a is folded in half so that the group 31 of the wire harness 30 is sandwiched in the nonwoven material 20a (see FIG. 5). At this time, the group 31 of the wire harness 30 is arranged in the half region on the fold 20b side of the folded nonwoven material 20a. Moreover, it is preferable to arrange the plurality of electric wires 32 belonging to the group 31 of the wire harness 30 in a parallel state so as to be as flat as possible.

  Next, the nonwoven material 20a is hot pressed (see FIG. 6). Here, hot pressing refers to molding the nonwoven material 20a by sandwiching the nonwoven material 20a, which is an object to be processed, between molds and applying pressure to the mold in a heated state. Here, for example, as shown in FIG. 9, hot pressing can be performed by sandwiching the nonwoven material 20a between a pair of molds 40 having a flat mold surface 40a. The mold 40 is provided with a heating unit 42 such as a heater, and the mold 40 can be heated by the heating unit 42.

  Thus, the non-woven material 20a is hot-pressed with the group 31 of the wire harness 30 sandwiched therebetween, so that it is processed into a flatter sheet shape, and the overlapping portion of the non-woven material 20a is joined to the inside. The non-woven member 20 holding the group 31 of the wire harness 30 can be obtained.

  When hot-pressing the nonwoven material 20a, the whole nonwoven material 20a may be hot-pressed, or the flat portion 21 excluding the portion that forms the folds 22 in the nonwoven material 20a may be hot-pressed. You may make it press. By making it like the latter, the crease | fold 22 can be easily formed in a later process. Here, the latter example will be described. Moreover, you may remove the part which accommodated the group 31 of the wire harness 30 among the nonwoven materials 20a from the object of a hot press.

  Next, slits 24 are formed between portions of the non-woven member 20 where the folds 22 are to be formed (see FIG. 7). The slit 24 can be formed with scissors, a cutter, a pressing blade, or the like. That is, the portion of the non-woven member 20 on the one side portion side is the electric wire housing portion 20A, and the side edge portion 20B that is hot-pressed to be flat on one side portion of the electric wire housing portion 20A is provided. The slit 24 is formed in the side edge portion 20B.

  Thereafter, the non-woven member 20 is folded to form a fold 22, and two non-woven members 20 folded in a zigzag are prepared.

  In forming the fold line 22, the non-woven member 20 may be simply folded by applying an external force, or may be hot pressed at the fold line 22. In the latter case, as shown in FIG. 10, in a state where the nonwoven member 20 is folded, the fold line 22 may be sandwiched between a pair of partially heated molds 140 and heated and pressurized. The mold 140 is also preferably heated by a heating unit 142 such as a heater. Thus, the non-woven member 20 can be firmly contracted and deformed by hot pressing the fold 22. Even when the crease 22 is not hot-pressed in this way, the non-woven member 20 and the electric wire 32 inside thereof can be crimped in the shrinking direction.

  Then, a pair of non-woven members 20 are arranged so that the folds 22 of each other face in opposite directions and the slits 24 of each other face each other, and the opposing slits 24 are fitted together (FIG. 8). reference). The fitting portion may be left as it is, or may be joined with an adhesive or the like. What is necessary is just to be able to change the crossing angle between the nonwoven members 20 in the fitting part.

  The wire harness 10 with a guide body is manufactured by the above.

  According to the wire harness with guide body 10 configured as described above, the pair of non-woven members 20 are arranged in a state where the respective folds 22 are shifted around the outer periphery (here, facing the outer periphery). In this state, the elongated guide body 26 that can be expanded and contracted is combined. For this reason, each non-woven member 20 complements each other, and the easiness of bending to a specific direction can be negated. Thereby, the guide body 26 becomes easy to expand and contract in a state where the linear state is maintained, and the extra length absorption state of the wire harness 30 can be stabilized. Thereby, interference with the surrounding member can be suppressed for the wire harness 10 with a guide body, and a contact sound, abrasion, damage, etc. can be suppressed.

  In particular, since the pair of non-woven members 20 form a continuous rhombus and are combined so as to constitute a guide body 26 that can be expanded and contracted by changing the folding angle of each fold line 22, a wire with a guide body The harness 10 can be expanded and contracted more reliably while maintaining a straight line state. Thereby, interference with a surrounding member as well as contact sound, wear, damage, etc. can be more reliably suppressed in the wire harness with guide body 10.

  Moreover, since the guide body 26 is comprised by forming the slit 24 in a pair of nonwoven members 20 and fitting each other slit 24 together, the said guide body 26 can be manufactured easily.

  Moreover, since the electric wire accommodating part 20A is provided in the one side part of the non-woven member 20, and the slit 24 is formed in the side edge part 20B hot-pressed in the one side part of the electric wire accommodating part 20A, the non-woven member 20 Thus, the slit 24 for combination can be easily formed while protecting the electric wire 32.

  Moreover, since the group 31 of the wire harness 30 is accommodated in the non-woven member 20, the extra length can be absorbed while protecting the electric wires 32 of the group 31 from being visible from the outside.

  Moreover, as a result of being able to absorb the extra length of the wire harness 30 as described above, the route design of the entire wire harness becomes simple, and the incorporation thereof becomes easy.

  In addition, the guide body 26 has an advantage that it can be manufactured in a state of being integrated with the wire harness 10 relatively easily by folding the nonwoven member 20 as appropriate and hot pressing.

{Second Embodiment}
The wire harness 210 with a guide body according to the second embodiment will be described. FIG. 11 is a partial perspective view showing a wire harness with guide body 210 according to the second embodiment.

  Similar to the first embodiment, the wire harness with guide body 210 is disposed between two members and used as a wiring for electrically connecting the two members. Examples of the two members and application examples thereof are as described in the first embodiment.

  The wire harness with guide body 210 includes a pair of non-woven members 220 and a wire harness 230 (see FIGS. 12 to 17).

  The non-woven member 220 is folded in a zigzag manner at a plurality of folds 222 as in the first embodiment. In the present embodiment, a more specific processing example of the non-woven member 220 will be described later.

  The wire harness 230 has at least one electric wire. Here, the wire harness 230 has a plurality of electric wires and is divided into two groups, as in the first embodiment. The group 231 of one wire harness 230 is accommodated in one nonwoven member 220, and the group 231 of the other wire harness 230 is accommodated in the other nonwoven member 220. A specific example in which the non-woven member 220 accommodates the group 231 of the wire harness 230 will be described later.

  However, as described in the first embodiment, the wire harness 230 has a plurality of electric wires, the electric wires are circular in cross section, and the electric wires are connected to both the pair of non-woven members 220. It is not essential that the wire is accommodated, the electric wire is accommodated in the non-woven member 220, or the like.

  The pair of non-woven members 220 are combined so as to form a long guide body 226. In the combined state, the pair of non-woven members 220 are combined so that the folds 222 are alternately folded in a state where the respective folds 222 are arranged so as to be shifted by 90 degrees around the center of the guide body 226.

  According to the wire harness 210 with a guide body according to the second embodiment, the folding angle of the fold 222 can be changed and expanded and deformed. At this time, both the non-woven members 220 are unlikely to bend in the extending direction (that is, the width direction) of the fold line 222, and are easily bent in a direction perpendicular to the direction. And since such a non-woven member 220 is combined in a state where the respective folds 222 are arranged so as to be shifted by 90 degrees around the center of the guide body 226, it is difficult to bend as a whole. ing. For this reason, the wire harness 210 with a guide body can be expanded and contracted while maintaining a linear state. Accordingly, as in the first embodiment, when the attachment member 60 is attached, the wire harness with guide body 210 is set in an extended state, thereby facilitating connection work between the wire harness with guide body 210 and the attachment member 60. In a state where the attached member 50 is attached to the attachment member 60, the wire harness with guide body 210 can be reduced and deformed while maintaining a straight state, and can maintain a state in which it is difficult to interfere with surrounding members. .

  With reference to FIGS. 12-17, the example of a manufacturing method of the said wire harness 210 with a guide body is demonstrated.

  First, two strip sheet-like nonwoven materials 220a are prepared, and a group 231 of wire harnesses 230 is disposed on one main surface of one nonwoven material 220a (see FIG. 12). The nonwoven material 220a used here is the same as that described in the first embodiment.

  Then, the other nonwoven material 220a is overlaid on one nonwoven material 220a, and the group 231 of the wire harness 230 is sandwiched between the two nonwoven materials 220a (see FIG. 13).

  Next, the nonwoven material 220a is hot pressed (see FIG. 14). As a result, the pair of non-woven materials 220a overlapped is processed into a flatter sheet, and the overlapping portions of the pair of non-woven materials 220a are joined to hold the group 231 of the wire harness 230 inside. A non-woven member 220 can be obtained.

  In addition, when hot-pressing the nonwoven material 220a, the whole nonwoven material 220a may be hot-pressed as in the first embodiment, or the fold 222 is formed in the nonwoven material 220a. Alternatively, the flat portion 221 excluding the portion to be hot-pressed may be hot pressed. Here, the latter example will be described. Moreover, the nonwoven material 220a may be hot-pressed only on the side portion.

  Next, two non-woven members 220 processed as described above are prepared, and arranged in an orthogonal state so that the ends thereof overlap each other (see FIG. 15).

  Then, one nonwoven member 220 is folded at the edge of the other nonwoven member 220 to form a fold 222, and the one nonwoven member 220 is folded on the other nonwoven member 220 (see FIG. 16). ).

  Similarly, the other non-woven member 220 is folded at the edge of one non-woven member 220 to form a fold 222, and the other non-woven member 220 is folded on one non-woven member 220 (FIG. 17). reference).

  When the above is repeated alternately, the non-woven members 220 are zigzag-folded at the plurality of folds 222, and the guide members 226 (in combination with the respective folds 222 being shifted by 90 degrees around the center). A guide-attached wire harness 210) is obtained.

  As in the first embodiment, the fold 222 may be formed by simply applying an external force to the non-woven member 220, or may be formed by hot pressing. Also good. In the latter case, the fold 222 may be formed by hot pressing before the two nonwoven members 220 are combined, or the folds 222 are sequentially hot when the two nonwoven members 220 are combined. It may be formed by pressing.

  According to the wire harness with guide body 210 configured as described above, the pair of non-woven members 220 are in a state where the respective folds 222 are shifted around the outer periphery (here, in a state where they are shifted by 90 degrees). ), And are combined so as to constitute an elongated guide body 226 that can be expanded and contracted. For this reason, the property of the ease of bending in a specific direction which each non-woven member 220 has can be mutually complemented and canceled. Thereby, the guide body 226 becomes easy to expand and contract in a state where the linear state is maintained, and the extra length absorption state of the wire harness 230 can be stabilized. Thereby, interference with the surrounding member can be suppressed for the wire harness 210 with a guide body, and a contact sound, abrasion, damage, etc. can be suppressed.

  Moreover, since the group 231 of the wire harness 230 is accommodated in the non-woven member 220, the extra length can be absorbed while protecting the wires of the group 231 from being seen from the outside.

  Moreover, as a result of the ability to absorb the extra length of the wire harness 230 as described above, the route design of the entire wire harness is simplified, and the incorporation thereof is also facilitated.

  Further, the guide body 226 has an advantage that it can be manufactured in a state of being integrated with the wire harness 210 relatively easily by folding the nonwoven member 220 as appropriate and hot pressing.

  FIGS. 18-21 is a figure which shows the example of a manufacturing method of the wire harness with a guide body which concerns on a modification.

  This modification is an example in which the wire harness 330 is not accommodated in the non-woven member 320.

  That is, two belt sheet-like nonwoven members 320 are prepared, and the wire harness 330 is disposed on one main surface of one nonwoven member 320 (see FIG. 18).

  Then, the end portion of the other non-woven member 320 is overlaid on the end portion of one non-woven member 320 and arranged in an orthogonal state (see FIG. 19).

  Thereafter, one non-woven member 320 is folded together with the wire harness 330 and is folded on the other non-woven member 320 (see FIG. 20).

  Next, the other nonwoven member 320 is folded on one nonwoven member 320 (see FIG. 21).

  When the above is repeated alternately, each non-woven member 320 is zigzag-folded at a plurality of folds 322, and the guide members (guides) are combined in a state where the respective folds 322 are shifted by 90 degrees around the center. Body wire harness) is obtained.

  In addition, the part except the crease | fold 322 among the said guide bodies is good to be processed into a thinner sheet-like shape by hot press. The processing may be performed in a state before combining the non-woven members 320 or in a subsequent state. Even after the two nonwoven members 320 are combined, hot pressing can be performed by using as thin a mold as possible.

  In addition, all or a part of the fold line 322 may be processed into a shape that maintains the folded state by hot pressing.

{Modifications}
In addition, the combination example of a pair of nonwoven members is not restricted to the said example. If the pair of non-woven members are combined so as to form an elongate guide body that can be expanded and contracted in a state in which the respective folds are shifted around the outer periphery, in a predetermined direction that each non-woven member exhibits Can be canceled each other, and as a result, it can be expanded and contracted in a straight line as much as possible.

  Moreover, each structure demonstrated by said each embodiment and modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
