  Hereinafter, the wire harness using the protective material for wire harnesses which concerns on embodiment, its manufacturing method, and the protective material for wire harnesses are demonstrated.

<Protective material for wire harness>
First, the protective material 10 for wire harnesses is demonstrated (refer FIG. 2, FIG. 3). The wire harness protective material 10 is a member that protects the electric wire 1 in a tubular form covering the periphery of the electric wire 1.

  For convenience of explanation, the wire 1 to be protected will be described. The electric wire 1 is an electric wire incorporated in a wire harness mounted on a vehicle such as an automobile, and may be either an electric wire bundle in which a plurality of electric wires are bundled or a single electric wire. The electric wire 1 has a portion that comes into contact with a peripheral member depending on the routing route, and wear may be caused by vibration of the vehicle. The wire harness protective material 10 is a member for protecting such a portion of the electric wire 1.

  The protective material 10 for wire harnesses is composed of a net-like sheet body formed by intersecting a plurality of vertical wires 4 and a plurality of horizontal wires 6 which are thermoplastic resin wires in a mesh shape (see FIG. 1). ).

  Here, the protective material 10 for wire harnesses comprised of a net-like sheet body is formed of polypropylene (PP). But the material of the protective material 10 for wire harnesses is not restricted to a polypropylene, Polyethylene (PE), polyvinyl chloride (PVC), etc. can be employ | adopted for others.

  A net-like sheet body is manufactured as follows, for example. That is, on the outer peripheral side of the vertical line mold in which a plurality of substantially circular grooves are formed in a spiral shape on the outer peripheral portion of the columnar body, a plurality of circular cross sectional views are substantially circular on the inner peripheral portion of the cylindrical body. The horizontal line mold in which the groove is formed is fitted so as to be relatively rotatable, and the molten resin is pushed out through each groove part while the vertical line mold and the horizontal line mold are relatively rotated. A cylindrical body is formed in which a plurality of vertical wires 4 and a plurality of horizontal wires 6 on the outer peripheral side are bonded at intersections. The cylindrical body is cooled in water or the like to maintain the shape, and is formed as a net-like sheet body by cutting a part in the circumferential direction with a cutting blade. This net-like sheet body is formed in a continuous band shape, and is used by being cut according to the size of the protective material 10 for wire harness.

  The protective material 10 for wire harness has the bending part 12 by which the net-shaped sheet body was bend-deformed and formed in the convex shape or the concave shape (refer FIG. 3). The bent portion 12 is formed in at least one place in the circumferential direction of the wire harness protective material 10 that is bent into a cylindrical shape (see FIGS. 2 and 6). That is, the bent portion 12 is provided so as to extend in the central axis direction in a state where the wire harness protective material 10 is bent into a cylindrical shape. The term “extending in the direction of the central axis” here is not limited to the case of being parallel to the central axis, but also includes the case of extending in the central axis direction while being inclined in one circumferential direction with respect to the central axis. That is, in the wire harness 120 to be described later, when the strip-shaped wire harness protective material 10 is wound around the electric wire 1 in a spiral shape, the extending direction of the wire harness protective material 10 is inclined with respect to the circumferential direction. As a result, the bent portion 12 is inclined with respect to the central axis. Therefore, the bent portion 12 may be inclined with respect to the central axis within a range inclined by spiral winding.

  The wire harness protective material 10 has a rectangular shape in plan view as a whole, and the bent portions 12 and the flat portions 14 are alternately formed. More specifically, a plurality of bent portions 12 and flat portions 14 are formed in parallel (here, at equal intervals) (see FIG. 3). Here, the bent portion 12 and the flat portion 14 extend along one end side and the other end side of the rectangular shape, and are alternately formed in parallel in a direction connecting the one end side and the other end side.

  The bent portion 12 is formed in a triangular wave-like convex shape in a cross-sectional view orthogonal to the extending direction. This bent portion 12 has a height in the inner and outer directions in the form in which the wire harness protective material 10 is bent, and when wear occurs due to contact with a peripheral member, the bent portion 12 is between the distal end portion and the proximal end portion. Thus, the reachable distance is secured in the inner and outer directions, thereby contributing to the improvement of protection performance. That is, generally, the wear of the wire harness protective material 10 is caused by rubbing due to vibration or the like in a state where the surface of the peripheral member is in contact with the outer peripheral portion of the wire harness protective material 10, so that the bent portion 12 is formed. In this position, a reachable distance corresponding to the height of the bent portion 12 is ensured, and the electric wire 1 can be protected with durability against wear.

  Moreover, the flat part 14 is a part which connects the edge parts (base end part) of the adjacent bending part 12 in substantially linear form (refer FIG. 3). And if the protective material 10 for wire harnesses is bent, the flat part 14 will curve along the circumferential direction of a bending form.

  The distance between the bent portions 12, that is, the number in the circumferential direction of the wire harness protective material 10 bent into a cylindrical shape is difficult to bend due to the diameter of the wire 1 to be protected, the thickness dimension of the net-like sheet body, the material, and the like. It may be determined in consideration of the amount of material (material cost) and the protection performance by securing the reach distance. From the viewpoint of improving the ease of bending deformation and the protection performance, it is preferable that more bent portions 12 are formed, but it is preferable to determine the balance with the amount of material used. Further, the height dimension of the bent portion 12 may be determined in the same manner.

  For example, when the diameter of the electric wire 1 to be protected is 5 mm (32 mm), the wire harness protective material 10 has a 2.6 mm (4.4 mm) interval between the vertices of the bent portions 12 and the height dimension of the bent portions 12. Can be set to 1.2 mm (2.8 mm).

  And if this wire harness protective material 10 is bent into a cylindrical shape, the outer peripheral portion has a longer extending path than the inner peripheral portion of the bent form, so that a circumferential compressive force is applied to the inner peripheral portion and the outer peripheral portion. A circumferential tensile force acts on the. Here, since the inner peripheral side portion of the bent portion 12 is shortened in the circumferential direction when the wire harness protective material 10 is bent (that is, the adjacent flat portions 14 are close to each other), the inner peripheral portion of the bent portion 12 is The bending difficulty due to the path difference between the outer peripheral portion and the outer peripheral portion is suppressed, and the flat portions 14 on both sides of the bent portion 12 are easily bent along the outer peripheral portion of the electric wire 1 (see FIG. 7). That is, the protective material 10 for wire harnesses can smoothly bend and deform when it is attached to the electric wire 1 by starting from the bent portions 12 formed in plurality and suppressing difficulty in bending.

  But the protective material 10 for wire harnesses is not restricted to the said structure. That is, the number of the bent portions 12 is not limited to the case where a plurality of the bent portions 12 are formed in the circumferential direction of the wire harness protective material 10 in a form bent into a cylindrical shape, and only one bent portion 12 may be provided.

  Moreover, the structure of the protective material 110 for wire harnesses as shown in FIG. 4, FIG. 8 is also employable. The protective member 110 for the wire harness has the flat portion 14 omitted, and a plurality of bent portions 12 are continuously formed in parallel. That is, the wire harness protective material 110 has a continuous triangular wave shape in a cross-sectional view orthogonal to the extending direction of the bent portion 12.

  When the wire harness protective material 110 is bent into a cylindrical shape, the inner peripheral side portion of the bent portion 12 is shortened in the circumferential direction (that is, the proximal end portions of the adjacent bent portions 12 are close to each other) and the outer periphery. The side portions are enlarged in the circumferential direction (that is, the front ends of the adjacent bent portions are separated in the circumferential direction). Thereby, the protective material 110 for wire harnesses can bend and bend smoothly when the wire harness is mounted on the electric wire 1 by bending each bent portion 12 as a starting point and suppressing the bending difficulty.

  Moreover, the protective material 10 for wire harnesses has a rectangular shape in plan view as a whole, and the bent portion 12 and the flat portion 14 extending along one end side and the other end side are connected in a direction connecting the one end side and the other end side. Although the shapes provided alternately in parallel have been described, the present invention is not limited to this. That is, the configuration of the wire harness protective material 210 having the bent portion 212 and the flat portion 214 formed to be inclined with respect to one end side and the other end side of the net-like sheet body can also be employed (see FIG. 5). . Such a protective material 210 for wire harness is good to be used for the wire harness 120a mentioned later (refer FIG. 16).

  Further, the bent portion 12 is not limited to a convex shape having a triangular wave shape in a sectional view, and may be a convex shape having a rectangular wave shape or a sine wave shape in a sectional view. Moreover, the bending part 12 is not restricted to the convex shape which becomes convex toward the outer peripheral side, The concave shape which becomes convex toward the inner peripheral side may be sufficient. In this case, the flat part 14 is located in the outer peripheral part.

<Manufacturing method>
Next, the manufacturing method of the said protective material 10 for wire harnesses is demonstrated (refer FIGS. 10-13).

  In this production method, the step (a) of heating the net-like sheet formed of the above-mentioned thermoplastic resin, and the net-like sheet that is heated and plastically deformed in the step (a) are bent to form a convex shape. Or the protective material 10 for wire harnesses is manufactured through the process (b) which forms a concave-shaped bending part (here several). In addition, a process (a) may be performed previously and a process (a) and a process (b) may be performed in parallel.

  Here, the example which performs a process (a) and a process (b) in parallel is demonstrated. That is, the net-like sheet body spreading in a planar shape is sandwiched across the entire central axis direction of the tubular form at two spaced intervals (see FIG. 11). Next, the two sandwiched portions are brought close to each other and the portion between the sandwiched portions is loosened and bent. The bent portion is further sandwiched in the approaching direction and bent and deformed, and the portion is heated to plastically deform the net-like sheet (see FIG. 12). Then, the bending part 12 is formed by canceling the clamping force (see FIG. 13). Subsequently, a plurality of bent portions 12 may be formed at equal intervals in the same procedure as described above. The protective material 10 for wire harnesses is manufactured by the above process.

  This operation can also be performed by the following apparatus, for example. In other words, a pair of chuck mechanisms 50 with a heating plate are provided at an interval so as to oppose the heating plate, and one chuck mechanism 50 is disposed so as to be capable of moving relative to and away from the other chuck mechanism 50. The feed roller 60 is configured to feed the net-like sheet body 50. Then, the net-like sheet body is fed by the feed roller 60 (see FIG. 10), the net-like sheet body is sandwiched by the pair of chuck mechanisms 50, and the pair of chuck mechanisms 50 are relatively moved in this state (see FIG. 11). In addition, the net-like sheet body is bent between them and is plastically deformed in a state of being bent by being sandwiched between opposed heating plates (see FIG. 12).

  Further, the protective material 10 for the wire harness sandwiches the net-like sheet body from both sides in the thickness direction by a pair of dies having alternately a triangular wave surface and a flat surface for forming the bent portion 12 and the flat portion 14. It can also be manufactured by press molding. In this case, the pair of molds themselves may be heated and press-molded, or the net-like sheet body may be pre-heated with a heater or the like and then press-molded. And the protective material 10 for wire harnesses is manufactured by plastically deforming a net-like sheet body in the form in which the bending part 12 was formed. The above-described wire harness protective material 210 can also be formed by changing the extending direction of the surface for forming the bent portion 212 and the flat portion 214 from the mold.

  Molding by a mold can also be realized by a mechanism in which a net-like sheet body is sandwiched between a pair of roller-shaped molds having surfaces for forming the bent portion 12 and the flat portion 14 on the outer peripheral surface. it can.

  Here, the temperature which heats a net-like sheet body in a process (a) is the temperature (temperature near melting | fusing point) which becomes soft to such an extent that a net-like sheet body can be plastically deformed. Here, polypropylene (PP) is used as the material for the net-like sheet body, and since the melting point is 125 ° C., the temperature of the heating plate or heater is set to the same or higher temperature (for example, 180 ° C.). Then, the net-like sheet body is heated to around 125 ° C. by adjusting the heating time.

  Moreover, the protective material 110 for wire harnesses described above is manufactured by bending and deforming the net-like sheet body and continuously forming the bent portions 12 in parallel in the step (b). The wire harness protective material 110 can be manufactured using a mold (not shown) having a continuous triangular wave surface for forming the continuous bent portion 12.

<Wire harness>
Next, the wire harness 20 using the wire harness protective material 10 described above will be described (see FIG. 14). The wire harness 20 includes an electric wire 1 and a protection unit 22.

  The protection part 22 is formed by bending the wire harness protection material 10 into a cylindrical shape covering the periphery of the electric wire 1 in a posture in which the bent part 12 is along the central axis direction of the electric wire 1. More specifically, the protective part 22 has a wire harness protective material 10 formed in a rectangular shape with respect to the part where one end side part of the electric wire 1 is already wound around the electric wire 1. It is formed by being wound in a shape overlapping the radial direction of the electric wire 1 (see FIGS. 6 and 14). The part that overlaps the part already wound around the electric wire 1 in the protective part 22 is either a form in which the bent parts 12 overlap, a form in which the flat parts 14 overlap, or a form in which the bent parts 12 and the flat parts 14 overlap each other. It is good that the protective material 10 for wire harness is wound so that it may become a form of this. And the protection part 22 is formed in the circumference | surroundings of the electric wire 1 by maintaining the shape bent by the tape 30 around the wire harness protective material 10 wound around the electric wire 1 from the outer peripheral side. (See FIG. 6).

  Moreover, the protective material 210 for wire harnesses may be wound around the electric wire 1 like the above (illustration omitted). Also in this case, in the protection part 22, the part where the wire harness protection material 210 is overlapped with the part already wound around the electric wire 1 is such that the bent part 212 and the flat part 214 overlap each other in the radial direction of the electric wire 1. It is wrapped so that

  Moreover, the wire harness 20a which has the protection part 22a formed by the protective material 110 for wire harnesses being wound around the electric wire 1 similarly to the above can also be comprised (refer FIG. 8). In this case, in the protective portion 22a, the portion overlapping the portion already wound around the electric wire 1 is in a form in which the bent portions 12 overlap with each other in the radial direction of the electric wire 1 so as to protect the wire harness protective material 110. Should be wrapped around.

  In addition, as shown in FIG. 15, the wire harness 120 can be configured by adopting a protection portion 122. The protection part 122 is formed by winding the wire harness protection material 10 formed in an elongated band shape around the electric wire 1 in a spiral shape. More specifically, the protection portion 122 is formed by connecting the wire 1 to the portion in which the edge on the one side in the width direction is already wound around the wire 1 every time the wire strip protection material 10 is wound once. It is good to be formed by being wound in a shape overlapping in the radial direction. Moreover, the protective material 10 for wire harnesses is good to be wound with the bending part 12 and the flat part 14 overlapping with respect to the part already wound around the electric wire 1. FIG. Since the wire harness protective material 10 that forms the main protective portion 122 has a shape in which the bent portion 12 and the flat portion 14 extend in a straight line parallel to the one end portion and the other end portion, Each bent portion 12 extends while being inclined in one circumferential direction with respect to the central axis direction of the electric wire 1.

  Further, when the wire harness protective member 210 formed in the shape of an elongated band is wound around the electric wire 1 in a spiral manner, the bent portion 212 and the flat portion 214 extend substantially parallel to the central axis direction of the electric wire 1. The protection part 122a of a form can be comprised (refer FIG. 16). In this case as well, the strip-shaped wire harness protective material 210 is formed by being wound on the edge on one side in the width direction so that the bent portion 212 and the flat portion 214 overlap each other in the radial direction of the electric wire 1. It is good to be.

  Moreover, the wire harness which has the protection part which covers the circumference | surroundings of the electric wire 1 can also be comprised using the strip | belt-shaped wire harness protective material 110 (illustration omitted). This protective portion is formed by winding a strip-shaped wire harness protective material 110 around the electric wire 1 in the same manner as the protective portion 122. In this case, in the protective portion, the portion overlapping the portion already wound around the electric wire 1 is such that the bent portions 12 are the diameter of the electric wire 1 at the edge portion on one side in the width direction of the protective material 110 for the wire harness. The wire harness protective material 110 may be wound around so as to overlap in the direction.

  According to the wire harness protective material 10 according to the above-described embodiment, the plurality of vertical wires 4 and the plurality of horizontal wires 6 are configured to intersect each other in a mesh shape, and are bent and deformed to form a triangular wave-like convex shape. Since it has a part, it is easy to bend and it is possible to improve the attachment workability to the electric wire 1. Moreover, according to the structure by which the bending part 12 was formed in multiple numbers in parallel, it can bend more smoothly and the attachment workability | operativity with respect to the electric wire 1 can be improved more.

  Moreover, according to the protective material 110 for wire harnesses in which a plurality of the bent portions 12 are continuously formed in parallel, in the form covering the periphery of the electric wire 1, the reach distance in wear due to contact with peripheral members is continuously increased. It can be ensured and contributes to improvement of protection performance.

  Moreover, according to the wire harness 20 using the protective material 10 for wire harnesses, the protective material 10 for wire harnesses is in the cylinder shape which covers the circumference | surroundings of the electric wire 1 in the attitude | position in which the bending part 12 extends in the extension direction of the electric wire 1. Since it is bent, the bending portion 12 is bent as a starting point, and the bending portion 12 expands and contracts in the circumferential direction, thereby suppressing the difficulty of bending due to the path difference between the outer peripheral portion and the inner peripheral portion. Therefore, the wire harness 20 can be configured by easily attaching the wire harness protective material 10 to the electric wire 1.

  Moreover, the protective material 10 for wire harnesses formed in the rectangular shape is wound around the electric wire 1 in such a shape that a portion on one end side is overlapped with a portion on the other end side in the radial direction of the electric wire 1. Thus, according to the wire harness 20 in which the protection part 22 is formed, the bent part 12 extends along the extending direction of the electric wire 1, and the electric wire 1 can be held linearly.

  Moreover, according to the wire harness 120 in which the protection part 122 is formed by forming the protective material for the wire harness in the shape of an elongated band and spirally wound around the wire 1, the wire harness 120 is adjacent to the extending direction of the wire 1. When the protective material 10 for wire harnesses is relatively displaced, the protected electric wire 1 is easily bent.
