  The present invention relates to a binding band for fastening a linear object.

  Patent Document 1 discloses a binding band that forms a linear portion in the cross-sectional shape of a wire harness. The binding band of Patent Document 1 is a band clip including a band-shaped band portion, a main body portion, and a vehicle fixing portion, and the band portion is provided with two bending promotion portions, and between the two bending straight portions. A straight line promoting portion is provided. And two bending promotion parts are each distribute | arranged to the both sides of the linear part of a wire harness, and a linear acceleration part is distribute | arranged along the linear part of a wire harness.

JP2015-1000022

  However, in the case of the conventional band clip, the positions of the two bending promoting portions in the band portion are fixed. For this reason, it may be difficult to cope with the diameter of the wire harness. For example, when the wire harness is relatively thin, it may be difficult to firmly tighten the wire harness. In addition, if the wire harness is thicker than the width between the bend promoting portions, the wire harness cannot be properly accommodated between the two bend promoting portions, which may make it difficult to appropriately flatten the wire harness.

  Then, an object of this invention is to provide the binding band which can be tightened firmly, flattening a linear thing.

  In order to solve the above problems, a first aspect is a binding band wound around a linear object, wherein a band part extending in a band shape and one end of the band part are connected, and an intermediate part of the band part And a tubular member having a through hole through which the band portion is inserted.

  Moreover, a 2nd aspect is a binding band of a 1st aspect, Comprising: Two said cylindrical members are attached with the space | interval provided in the said band part.

  Moreover, a 3rd aspect is a binding band of a 1st aspect or a 2nd aspect, Comprising: The said cylindrical member is formed with rubber | gum.

  Moreover, a 4th aspect is a binding band any one of the 1st aspect to the 3rd aspect, Comprising: The said cylindrical member is provided so that a sliding contact movement is possible with respect to the said band part.

  Moreover, a 5th aspect is a wire harness with an exterior member, Comprising: The wire harness, the exterior member attached to the outer peripheral part of the said wire harness, and any one binding band of the 1st aspect to the 4th aspect, A projecting piece projecting in the extending direction of the exterior member is provided at an end of the exterior member, and the band portion of the binding band is wound around the outer periphery of the wire harness, The band is fixed to the band fixing portion of the binding band while being passed through an insertion hole formed in the protruding piece.

  According to the binding band of the first aspect, the rigidity of the band portion to which the cylindrical member is attached can be increased by inserting the cylindrical member into the band portion. Thereby, when a band part is wound around a linear object, a linear object can be planarized in the location where the cylindrical member of the band part was attached. Further, by attaching the tubular member to the band portion, it can be firmly tightened regardless of the diameter of the linear object.

  According to the binding band of the second aspect, the linear object can be flattened by sandwiching the linear object between the two cylindrical members.

  According to the binding band of the third aspect, by forming the cylindrical member with rubber, it is possible to increase the frictional force between the cylindrical member and the linear object. Shifting can be suppressed. Moreover, when a linear object is comprised with the several wire, it can bind suitably, suppressing the lateral shift of each wire.

  According to the binding band of the fourth aspect, the cylindrical member can be moved along the band portion, and can be easily fixed at an arbitrary position. Thereby, the cylindrical member can be positioned at an appropriate position and applied to the linear object.

  According to the wire harness with an exterior member of the fifth aspect, the rigidity of the band part to which the cylindrical member is attached can be increased by inserting the cylindrical member into the band part. Thereby, when a band part is wound around a linear object, a linear object can be planarized in the location where the cylindrical member of the band part was attached. Further, by attaching the tubular member to the band portion, it can be firmly tightened regardless of the diameter of the linear object. Furthermore, since the projecting piece can be firmly attached to the wire harness, the projecting piece can be shortened.

In the drawings, the size and number of each part may be exaggerated or simplified as necessary for easy understanding.

<1. First Embodiment>
FIG. 1 is a schematic side view showing a binding band 10 of the embodiment. FIG. 2 is a schematic cross-sectional view showing the band fixing portion 14 of the embodiment. FIG. 3 is a schematic perspective view showing the tubular member 20 of the embodiment. FIG. 4 is a schematic side view showing an example of attachment of the binding band 10 of the embodiment.

<Binding band 10>
The binding band 10 is a member fixed to the linear object by fastening the linear object. Here, the case where it fixes to the linear part of the wire harness 90 as a linear object is demonstrated. However, the linear object is not limited to the wire harness. The wire harness 90 includes a plurality of electric wires for supplying power or communicating signals, and is used as a wiring material for connecting electrical devices in a vehicle such as an automobile.

  The binding band 10 includes a band portion 12, a band fixing portion 14, and a cylindrical member 20.

<Band part 12>
The band part 12 is a member extending in a band shape and is a part wound around the wire harness 90. The base end portion of the band portion 12 is connected to the band fixing portion 14. A plurality of locking grooves 122 are formed on the surface of the intermediate portion near the tip of the band portion 12. Here, the locking groove 122 is a V-shaped groove extending in the width direction of the band portion 12 in a sectional view.

<Band fixing part 14>
The band fixing part 14 is a part having a three-dimensional shape in which a band insertion hole 140 is formed. Here, the band fixing | fixed part 14 is formed in the square cylinder shape, and the square hole-shaped band penetration hole 140 is formed in the center part. The band portion 12 is inserted from one end side opening of the band insertion hole 140 toward the other end side opening.

  As shown in FIG. 1, in this example, the axial direction of the band insertion hole 140 is a direction intersecting with the direction in which the band portion 12 extends (specifically, a direction orthogonal to each other). It is good.

  As shown in FIG. 2, the band fixing portion 14 includes a band locking portion 142 inside the band insertion hole 140. The band locking portion 142 extends while being inclined with respect to the axial direction of the band insertion hole 140 from the position near the opening on the one end side of the band insertion hole 140 toward the opening on the other end side.

  A locking claw 144 is provided at the tip of the band locking portion 142. Here, three locking claws 144 are provided. The locking claw 144 is formed in a triangular projection shape in a sectional view. Each of the locking claws 144 is formed in a protruding shape extending toward the other side opening of the band insertion hole 140. The band locking portion 142 preferably includes three locking claws 144, but this is not essential.

  When the band portion 12 is inserted from the one end side opening of the band insertion hole 140 toward the other end side opening, the base end side portion of the band locking portion 142 is elastically deformed, whereby each of the locking claws 144 is The locking groove 122 of the band part 12 is easily climbed over. On the other hand, when the band portion 12 is pulled back from the other end side opening of the band insertion hole 140 to the one end side opening, each of the locking claws 144 is caught in the locking groove 122 of the band portion 12, so It is difficult to cross. As a result, the band portion 12 inserted through the band insertion hole 140 is prevented from being detached from the band insertion hole 140. By this action, the intermediate portion of the band portion 12 (the portion where the locking groove 122 is formed) is fixed to the band fixing portion 14.

<Cylindrical member 20>
The cylindrical member 20 is a member formed in a cylindrical shape, and a circular through hole 22 is formed at the center. The cylindrical member 20 is a part attached to the band part 12. The cylindrical member 20 presses the wire harness 90 and flattens the wire harness 90 as will be described later.

  The inner dimension of the through-hole 22 of the cylindrical member 20 is preferably a size that allows the band portion 12 to be inserted. For example, by making the inner dimension of the through hole 22 larger than the width of the band part 12, the tubular member 20 may be freely movable on the band part 12. When the cylindrical member 20 is configured to be elastically deformable, the inner dimension of the through hole 22 may be smaller than the width of the band portion 12. In this case, the band portion 12 may be inserted through the through hole 22 whose inner dimension is increased by crushing the cylindrical member 20.

  Further, the inner dimension of the through hole 22 is preferably such that the cylindrical member 20 can move while being in sliding contact with the band portion 12. Thereby, in the band part 12, while being able to move the cylindrical member 20 to arbitrary positions, the cylindrical member 20 can be stably fixed in the position after a movement. That is, the cylindrical member 20 can be easily positioned.

  In the binding band 10, two cylindrical members 20 are attached to one band portion 12 with a gap therebetween. However, only one cylindrical member 20 or three or more cylindrical members 20 may be provided for one band portion 12.

  Of the band portion 12, the portion where the tubular member 20 is attached is less likely to deform than the portion where the tubular member 20 is not attached. Thereby, as shown in FIG. 4, the cylindrical member 20 presses the wire harness 90 over the longitudinal direction. Therefore, the wire harness 90 can be flattened, whereby the diameter of the wire harness can be reduced. In particular, as shown in FIG. 4, the wire harness 90 can be flattened by pressing the wire harness 90 in a state where the pair of cylindrical members 20 are arranged to face each other.

  Moreover, by providing the tubular member 20 in the binding band 10, the wire harness 90 can be firmly tightened while flattening the wire harness regardless of the diameter of the wire harness 90.

  Moreover, the cylindrical member 20 can be comprised so that attachment or detachment is possible by setting the internal dimension of the cylindrical member 20 to the dimension which the cylindrical member 20 can extract from the band part 12. FIG. For example, a plurality of types of cylindrical members 20 having different dimensions in the longitudinal direction (the axial direction of the through hole 22) may be prepared, and the band member 12 may be selectively attached from these. Regardless of the diameter of the wire harness 90, the wire harness 90 can be suitably flattened by changing the dimensions of the cylindrical member 20 attached to the band portion 12. Further, the width of the flattened portion of the wire harness 90 can be changed.

  The tubular member 20 is preferably formed of rubber. The hardness of the rubber in this case is not particularly limited, but is preferably 60 to 80 degrees (conforming to JIS K 6253), for example. By forming the cylindrical member 20 with such a relatively hard rubber, the wire harness 90 can be suitably flattened.

  Further, when the cylindrical member 20 is formed of rubber, the frictional force of the cylindrical member 20 with respect to the wire harness 90 is increased. Thereby, the cylindrical member 20 can be stably fixed to a fixed position with respect to the wire harness 90. Moreover, when the wire harness 90 is comprised with the some electric wire (wire material), when the cylindrical member 20 presses the wire harness 90, the horizontal shift | offset | difference of the some electric wire which contact | connects the cylindrical member 20 among several electric wires is carried out. Can be suppressed. Thereby, it can suppress that the some electric wire bound is displaced mutually. Thus, by restraining the positional deviation of the electric wires, it is possible to omit the wire harness 90 from being separately bound by tape winding or the like.

  A plurality of convex portions may be formed on the surface of the cylindrical member 20. The size of the protrusion formed on the surface of the cylindrical member 20 is not particularly limited. For example, as shown in an enlarged view in FIG. It is done. By providing a plurality of convex portions, the frictional force of the tubular member 20 against the wire harness 90 can be increased.

  It is also conceivable that the cylindrical member 20 is formed of a material other than rubber (resin, metal, wood, etc.). In particular, when the tubular member 20 is formed of a material other than rubber, the wire harness 90 can be suitably flattened by forming a plurality of convex portions 202 on the surface.

  Further, as the tubular member 20, a heat shrinkable tube (a tube that shrinks in the radial direction by heating) may be employed. A heat-shrinkable tube may be disposed at a required position of the band portion 12 and then heat-shrinked to fix the heat-shrinkable tube at that position.

  Although not shown, the band fixing part 14 in the binding band 10 may be provided with a vehicle fixing part for fixing the binding band 10 to the vehicle. The vehicle fixing portion may have a structure described in Patent Document 1, for example. Specifically, the vehicle fixing portion may include a locking structure that locks against a hole formed in the vehicle. The wire harness 90 can be fixed to the vehicle by attaching the binding band 10 including the vehicle fixing portion to the wire harness 90.

<Wire harness 100 with exterior member>
Drawing 5 is an outline front view showing wire harness 100 with an exterior member of an embodiment. FIG. 6 is a schematic perspective view showing the exterior member 30 of the embodiment. FIG. 7 is a front view showing the exterior member 30 of the embodiment. 5-7, only the one end side of the exterior member 30 is shown, However, The exterior member 30 may be provided with the same structure also in the other end side.

  As illustrated in FIG. 5, the wire harness 100 with an exterior member includes a binding band 10, an exterior member 30, and a wire harness 90.

<Exterior member 30>
The exterior member 30 is a member that is attached to the outer peripheral portion of the wire harness 90 for the purpose of protecting the wire harness 90 or restricting the path. Specifically, the exterior member 30 includes a pair of plate-like portions 32 a and 32 a and a projecting piece portion 34. The exterior member 30 may be formed of resin (polyvinyl chloride, polypropylene, etc.), rubber, or the like. Moreover, the exterior member 30 may be obtained by hot pressing a nonwoven fabric. Hot pressing refers to molding by inserting a non-woven fabric, which is an object to be processed, into which an adhesive resin is added, between molds and applying pressure to the mold in a heated state. By hot pressing, the basic fibers contained in the nonwoven fabric are bonded to each other by the adhesive resin. Thereby, the nonwoven fabric is formed into a fixed shape.

  The pair of plate-like portions 32 a and 32 a are portions formed in a plate shape extending along the wiring path of the wire harness 90. Here, the pair of plate-like portions 32a and 32a are formed in a flat plate shape. As for a pair of plate-shaped part 32a, 32a, the edge part along a longitudinal direction is mutually connected. As shown in FIG. 7, the pair of plate-like portions 32 a and 32 a are connected so as to intersect in an L shape (here, orthogonal) in a front view, and a part of the periphery of the wire harness 90 is formed. cover. In addition, the shape of the exterior member 30 is not limited to L shape in front view, as shown in FIG. 7, For example, you may form in U shape or cyclic | annular form in front view.

  The projecting piece 34 is a portion that protrudes in the extending direction of the exterior member 30 at the end of the exterior member 30. Here, the protruding piece portion 34 is a portion protruding from one end portion of one plate-like portion 32a out of the pair of plate-like portions 32a, 32a, and is a portion formed in a rectangular plate shape. Note that the projecting piece portion 34 may also be formed on the other end side of the exterior member 30.

  The projecting piece portion 34 is provided with a binding band fixing portion 340. The binding band fixing portion 340 is a portion formed in a rectangular parallelepiped shape, and is provided on the outer side of the projecting piece portion 34 (that is, the surface opposite to the surface facing the wire harness 90). However, the position where the binding band fixing part 340 is provided is not limited to this.

  The binding band fixing part 340 is provided to fix the binding band 10. Specifically, the binding band fixing part 340 is formed with an insertion hole 342 through which the band part 12 is inserted.

  As shown in FIG. 5, the exterior member 30 is attached to the wire harness 90 via the binding band 10. Specifically, the exterior member 30 is applied to the outer peripheral portion of the wire harness 90, and in this state, the band in which the pair of tubular members 20 and 20 are attached to the portion of the wire harness 90 that protrudes from the tip of the exterior member 30. Part 12 is wound. And after inserting the front-end | tip part of the band part 12 into the insertion hole 342 of the binding band fixing | fixed part 340, and inserting it in the band fixing | fixed part 14 of the binding band 10, the wire harness 90 and the protruding piece part 34 are bound to the binding band. 10 and integrated. In this way, the exterior member 30 is attached to the wire harness 90.

  When routing the wire harness 90 to the vehicle, the wire harness 90 may not be routed in a circular shape in order to avoid interference with other members in the routing space. In the case of the wire harness 100 with the exterior member, since the tubular member 20 of the binding band 10 presses the wire harness 90, the portion of the wire harness 90 that protrudes from the exterior member 30 can be flattened. Therefore, the wire harness 90 can be routed according to the constraints of the routing space.

  By providing the tubular member 20 on the binding band 10, the wire harness 90 can be firmly tightened. For this reason, the exterior member 30 can be firmly attached to the wire harness 90 by using the binding band 10. For example, when the exterior member 30 is attached to the wire harness 90 by tape winding as in the prior art, the length of the projecting piece portion 34 needs to be formed long in order to secure the length of the tape winding. . On the other hand, when the binding band 10 is used, the protruding length of the protruding piece 34 can be shortened.

  As described above, by firmly tightening the wire harness 90 with the binding band 10, it is possible to suppress the lateral displacement of the plurality of electric wires constituting the wire harness 90. Furthermore, by increasing the frictional force on the surface of the cylindrical member 20, it is possible to further suppress the lateral displacement of the plurality of electric wires. Therefore, tape winding or the like for bundling electric wires can be omitted at the portion applied to the protruding piece 34 of the wire harness 90.

  Although the present invention has been described in detail, 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. The configurations described in the above embodiments and modifications can be appropriately combined or omitted as long as they do not contradict each other.
