<First Embodiment>
First, the configuration of the wire harness 10 according to the first embodiment of the present invention will be described with reference to FIGS. The wire harness 10 includes an electric wire 9 and a wiring tool 1. The wiring tool 1 is a member that is attached to the electric wire 9 and holds the electric wire 9 in a desired shape and protects the electric wire 9.

The first member 2 is a plate-like member on which a first pasting surface 412 including at least one of a loop surface 401 and a hook surface 402 constituting the pasting surface of the surface fastener 4 is formed. Further, the second member 3 is a member in which a second pasting surface 422 including at least the other of the loop surface 401 and the hook surface 402 constituting the pasting surface of the surface fastener 4 is formed.

  The loop surface 401 is a surface raised in a loop shape, and the hook surface 402 is a surface raised in a hook shape. When the raised portion of the hook surface 402 and the raised portion of the loop surface 401 are intertwined, the first application surface 412 and the second application surface 422 are maintained in an attached state.

  In this embodiment, each of the 1st sticking surface 412 and the 2nd sticking surface 422 is a sticking surface in which both the loop surface 401 and the hook surface 402 were formed. It is also conceivable that the first pasting surface 412 includes only one of the loop surface 401 and the hook surface 402 and the second pasting surface 422 includes only the other.

  The second member 3 is united with the first member 2 by the second bonding surface 422 being bonded to the first bonding surface 412 of the first member 2. In addition, the electric wire 9 passes between the first member 2 and the second member 3 in a state where the first member 2 and the second member 3 pass between the portions where the first attachment surface 412 and the second attachment surface 422 are attached. The shape is held by the two members 3.

  More specifically, in the wiring tool 1, the first member 2 is a plate-like member having irregularities, and includes a substrate portion 20 and a plurality of hollow raised portions 21. Moreover, the board | substrate part 20 contains the trough part 22 which makes the trough of a some hollow part. 1-3, the electric wire 9 is arrange | positioned along the trough part 22 of the 1st member 2. As shown in FIG. In the example shown in FIGS. 3 and 4, the substrate portion 20 has a flat plate shape, but it is also conceivable that the substrate portion 20 has an uneven plate shape.

  The first pasting surface 412 is formed at the top of each of the plurality of raised portions 21. In the example shown in FIGS. 3 and 4, a first surface fastener sheet 41, which is a sheet-like surface fastener material on which a first sticking surface 412 is formed, is bonded to the flat surface on the top of the raised portion 21.

  Since the tops of the plurality of raised portions 21 are formed flush with each other, the first pasting surface 412 formed separately in a plurality of regions is also formed flush with each other.

  The first surface fastener sheet 41 has a flexible sheet-like base portion 411, one of the front and back surfaces of the base portion 411 is the first sticking surface 412, and the other surface is the raised portion 21. Bonded to the top of the head.

  In the example shown in FIGS. 1 and 2, the plurality of raised portions 21 are formed side by side at equal intervals in each of the two intersecting directions R1 and R2. Accordingly, the valley portion 22 forms a lattice-like path along a plurality of parallel lines in each of the two directions R1 and R2 that intersect. In the example shown in FIGS. 1 and 2, the two directions R1 and R2 intersect at an angle of 90 °.

  The shape of the raised portion 21 is, for example, a cylindrical shape, a prismatic shape, or a shape of the remaining portion obtained by removing a part of the pyramid shape from the top of the pyramid. The shape of the raised portion 21 shown in FIGS. 1 to 4 is generally the shape of the remaining portion obtained by removing a portion of the regular quadrangular pyramid shape from the top of the regular quadrangular pyramid, but the side portion has a corner. It forms a rounded smooth surface. From the viewpoint of preventing damage to the electric wire 9, it is desirable that no corner is formed on the side surface of the raised portion 21.

  The substrate portion 20 and the raised portion 21 that are the remaining portions of the first member 2 excluding the first hook-and-loop fastener sheet 41 are integrally formed members of synthetic resin. For example, the substrate portion 20 and the raised portion 21 are synthetic resin members such as polypropylene (PP) or polyamide (PA).

  Further, the second member 3 in the present embodiment is a plate-like member in which a second pasting surface 422 is formed on the surface facing the first member 2. For example, the second pasting surface 422 is formed on the entire surface of the second member 3 that faces the entire first pasting surface 412 of the first member 2.

  In the example shown in FIGS. 3 and 4, the second surface fastener sheet 42, which is a sheet-shaped surface fastener material on which the second pasting surface 422 is formed, is the side corresponding to the first member 2 in the flat plate-like substrate portion 30. It is glued to the surface. The second surface fastener sheet 42 has a flexible sheet-like base portion 421, and one surface of the base portion 421 is a second sticking surface 422.

  The substrate portion 30 of the second member 3 is a synthetic resin member such as polypropylene (PP) or polyamide (PA).

FIG. 7 is a cross-sectional view of a portion of the wire harness 10 </ b> A that holds the electric wire 9. FIG. 8 is a cross-sectional view of the wire 9 and the wiring tool 1 </ b> A when assembled to the wire 9. Moreover, FIG. 7 is sectional drawing in the IV-IV plane shown by FIG.

  The wiring tool 1A includes a first member 2A and a second member 3A. The first member 2 </ b> A and the second member 3 </ b> A are maintained in a combined state by the hook-and-loop fastener 4. A part of the electric wire 9 is sandwiched between the first member 2 </ b> A and the second member 3 </ b> A so that the shape is maintained and protected.

  In the wiring tool 1 </ b> A, the first member 2 </ b> A has a flat plate-like substrate portion 20 in which a first pasting surface 412 is formed on one entire surface. In the example shown in FIGS. 3 and 4, a first surface fastener sheet 41, which is a sheet-like surface fastener material on which a first pasting surface 412 is formed, is bonded to one surface of the substrate portion 20.

  On the other hand, the second member 3A is a sheet-like member having flexibility, and a second pasting surface 422 is formed on the entire one surface thereof. In the example shown in FIGS. 7 and 8, the second member 3 </ b> A is the second surface fastener sheet 42 itself that is a sheet-like surface fastener material.

  As shown in FIGS. 1 and 2, a plurality of through holes are formed in the region where the first pasting surface 412 is formed in the first member 2 </ b> A. For convenience, the through hole of the first member 2 </ b> A is referred to as a first through hole 24. Similarly, a plurality of through holes are formed also in the region where the second pasting surface 422 is formed in the second member 3A. For convenience, the through hole of the second member 3 </ b> A is referred to as a second through hole 34.

  In a state where the first member 2A and the second member 3A are overlapped, each of the plurality of first through holes 24 and each of the plurality of second through holes 34 communicate with each other. The first through hole 24 and the second through hole 34 are formed along a plurality of paths including the branching portion.

  In the example shown in FIGS. 5 and 6, the plurality of first through holes 24 and the plurality of second through holes 34 communicating therewith are formed side by side at equal intervals in each of the two intersecting directions R1 and R2. Therefore, the 1st through-hole 24 and the 2nd through-hole 34 form the grid | lattice-like path | route along the some parallel straight line in each of two directions R1 and R2 which cross | intersect. 5 and 6, the two directions R1 and R2 intersect at an angle of 90 °.

  Further, the second through hole 34 formed in the second member 3A is formed larger than the first through hole 24 formed in the first member 2A.

  Next, an example of a procedure for attaching the wiring tool 1A to the electric wire 9 will be described with reference to FIG. In the example shown below, the figure board 8 is used. The plate 8 includes a base portion 80 on which a flat upper surface is formed, and a plurality of pins 81 that stand up along the upper surface of the base portion 80. The plurality of pins 81 are thick enough to pass through each of the plurality of first through holes 24, and are formed in the same positional relationship as the positional relationship of the plurality of first through holes 24.

  First, the first member 2A is placed on the drawing board 8 in a state where each of the plurality of pins 81 of the drawing board 8 passes through the first through holes 24 of the first member 2A. Thereby, each of the plurality of pins 81 stands up from each of the plurality of first through holes 24 in the flat first member 2A. In this state, the plurality of pins 81 function as protrusions that guide the route of the electric wires 9 instead of the raised portions 21 in the wiring tool 1.

  Next, the electric wire 9 is placed on the first member 2A. At that time, the electric wire 9 is placed on the first member 2 </ b> A in a state along any one of the plurality of paths formed by the plurality of pins 81. Therefore, the electric wire 9 is disposed along the first through hole 24 in the first member 2A.

  Next, the second member 3 </ b> A is overlaid on the first member 2 </ b> A and the electric wire 9 with each of the plurality of pins 81 of the drawing plate 8 penetrating the second through holes 34 of the second member 3 </ b> A. Further, the second sticking surface 422 of the second member 3A is stuck to the first sticking surface 412 of the first member 2A. Finally, the first member 2A and the second member 3A in a state of sandwiching the electric wire 9 are removed from the drawing board 8.

  By the procedure shown above, the 2nd member 3A will be in the state united with 1st member 2A because the 2nd sticking surface 422 has stuck to the 1st sticking surface 412. FIG. The electric wire 9 is sandwiched between the first member 2A and the second member 3A.

  In the wire harness 10A obtained by the procedure shown above, the electric wire 9 is a portion where the first application surface 412 and the second application surface 422 are bonded between the combined first member 2A and second member 3A. In a state of passing between the first member 2A and the second member 3A, the shape is maintained and protected.

<Effect>
In the wire harnesses 10, 10 </ b> A, the electric wire 9 has a first application surface 412 and a second application surface 422 in the surface fastener 4 between the first members 2, 2 </ b> A and the second members 3, 3 </ b> A combined by the surface fastener 4. The shape is held by these two members while passing between the pasted portions.

  That is, the first member 2, 2 </ b> A and the second member 3, 3 </ b> A surround the periphery of the electric wire 9 by the portion facing the electric wire 9 and the portion where the hook-and-loop fastener 4 is attached on both sides of the electric wire 9. The wire 9 is protected and the shape of the wire 9 is maintained.

  Moreover, since the 1st member 2,2A and the 2nd member 3,3A are fastened to the electric wire 9 by sticking the surface fastener 4 previously formed in both members, in order to attach the wiring tools 1, 1A to the electric wire 9 It is not necessary to attach other parts such as the necessary adhesive tape or binding belt.

  As described above, if the wire harness 10 or 10A is employed, the electric wire 9 is held and protected in a desired shape by the wiring tool 1 or 1A, and further the wiring tool 1 or 1A is attached to the electric wire 9. It is possible to reduce the number of parts and work man-hours required for attachment.

  Moreover, in the wiring tool 1, the 2nd sticking surface 422 of the 2nd member 3 functions as a shock absorbing material. Similarly, in the wiring tool 1A, the first sticking surface 412 of the first member 2A and the second sticking surface 422 of the second member 3A function as cushioning materials. Therefore, generation | occurrence | production of the noise by the electric wire 9 and the wiring tools 1 and 1A receiving a vibration is suppressed.

  Further, in the first member 2 of the wiring tool 1, the valley portions 22 forming the valleys of the plurality of raised portions 21 form a plurality of selectable paths. That is, the plurality of raised portions 21 function as protrusions that guide a plurality of selectable paths. Therefore, the wiring tool 1 can be applied to wire harnesses having various specifications in which the route of the electric wire 9 is different. Therefore, the freedom degree of design of a wire harness increases.

  Furthermore, in the wiring tool 1, the raised portion 21 and the valley portion 22 in the first member 2 can be easily obtained by vacuum forming a flat resin member. Vacuum molding is preferable in that it can be realized more simply than injection molding.

  On the other hand, in the wiring tool 1A, it is possible to pass a plurality of pins 81 that guide the route of the electric wire 9 into the region where the bonding surfaces of the first member 2A and the second member 3A constituting the wiring tool 1A are formed. A plurality of through holes 24 and 34 are formed. In this case, in the operation of arranging the electric wire 9 on the first member 2A and the operation of overlapping the second member 3A thereon, the positioning of the first member 2A, the second member 3A and the electric wire 9 is facilitated, which is preferable. .

  By the way, when the 2nd sticking surface 422 is affixed on the 1st sticking surface 412, since a part of 2nd member 3A curves along the electric wire 9, the position of the 2nd through-hole 34 with respect to the 1st through-hole 24 is the position. A little off. For this reason, when the second through hole 34 is small, the edge of the second through hole 34 is caught by the positioning pin 81, and the attachment of the hook-and-loop fastener 4 is inhibited.

  However, in the wiring tool 1A, the second through hole 34 is formed larger than the first through hole 24 so as to have sufficient play. As a result, the second member 3 </ b> A is stuck to the first member 2 </ b> A without being caught by the pin 81 of the plate 8.
