Description

  The present invention relates to a routing tool with a binding band, in which the routing tool is inserted through the band portion of the binding band.

  2. Description of the Related Art Conventionally, cable ties with a binding band have been widely used for the wiring of automobile wire harnesses and the like. For example, as shown in FIG. 1 of International Publication No. WO2008 / 093705 (Patent Document 1), the binding band and the band portion of the binding band are inserted into such a routing tool with a binding band. It is comprised including the routing tool provided with the band part penetration hole. The routing tool has a base part provided with a band part insertion hole and a projecting part projecting from the base part. As an example of the projecting part, the routing tool is fitted into an insertion hole penetrating a vehicle body panel or the like. And a cable holding portion for inserting and holding a long member such as a cable. A clip, which is a projecting portion projecting from the base, is fitted into a through-hole of a fixing member such as a vehicle body panel to hold a bound body such as a wire harness to which a binding band is bound at a specific position of the vehicle. can do. Moreover, a cable can be routed along a bound body such as a wire harness by fitting a cable or the like into a cable holding portion protruding from the base.

  By the way, in the routing tool with a binding band described in Patent Document 1, a hemispherical convex portion is projected in the band portion insertion hole, and after the binding band is wound around a binding body such as a wire harness, The routing tool can be temporarily fixed at a predetermined position on the binding band by the contact friction between the hemispherical protrusion and the band portion while allowing the routing tool to slide in the length direction of the binding band. Has been.

  However, in the conventional structure described in Patent Document 1, the positioning (temporary fixing) of the routing tool in the length direction of the band portion of the binding band is performed by a hemispherical protrusion protruding from the band insertion hole. Since it was only contact, there was a possibility that the routing tool could not be stably fixed temporarily at a desired position. In addition, there is a possibility that a bundled body such as a wire harness arranged due to vibrations during traveling of the vehicle may rattle, and in such a case, there is a risk that the routing tool may be displaced from a desired position. is there.

International Publication No. WO2008 / 093705

  The present invention has been made in the background of the above-described circumstances, and the problem to be solved is that the routing device is more stable with respect to the band portion of the binding band wound around the binding member such as the wire harness. Another object of the present invention is to provide a novel cable tie with a binding band that can be firmly held.

  In a first aspect of the present invention, in the routing device with a binding band formed by inserting a routing tool into the band portion of the binding band, the routing tool is a band portion through which the band portion of the binding band is inserted. A base portion having an insertion hole and a projecting portion projecting from the base portion are configured, and in both opening portions of the band portion insertion hole, toward the plate thickness direction of the band portion to be inserted. A protruding portion that protrudes and extends in the plate width direction of the band portion is provided.

  According to this aspect, in both openings of the band part insertion hole provided in the base part of the routing tool with the binding band, the plate of the band part protrudes in the thickness direction of the band part to be inserted. A ridge extending in the width direction is provided. As a result, as compared with the case where a hemispherical protrusion is provided in the band part insertion hole as in the prior art and the point is only in point contact with the band part, the projecting part has both openings of the band part insertion hole. In FIG. 3, the band portion is in line contact with the band portion in a direction orthogonal to the length direction of the band portion. Therefore, since the protruding portion extending in the direction orthogonal to the moving direction of the routing tool can contact the band portion with a large area and obtain a large frictional resistance, the band portion of the routing tool can be surely secured with a simple structure. Therefore, temporary fixing to the band portion of the routing tool can be realized with higher certainty as compared with the conventional structure. In addition, since the band portion and the routing tool are not concavo-convexly fitted, it is possible to slide the routing tool in the length direction of the band portion of the binding band as in the prior art.

  A second aspect of the present invention is the one described in the first aspect, wherein the protruding portion of the routing tool is a cable holding portion through which a cable is inserted.

  According to this aspect, since the protruding portion that protrudes from the base portion of the routing tool is configured by the cable holder, the circumference of the binding band that is bound around the binding object such as the wire harness. It is possible to temporarily fix the routing tool at a predetermined position and hold the cable there. At that time, the routing tool can be moved to a desired position on the circumference of the binding band, and the routing tool can be stably and temporarily fixed to the desired position by the frictional resistance between the ridge portion and the band portion. It can be advantageously and stably held at a predetermined position of the bundled body.

  A third aspect of the present invention is the one described in the first aspect, wherein the protruding portion of the routing tool is a clip portion that is fitted into a through hole of a fixing member.

  According to this aspect, since the projecting portion projecting from the base portion of the routing tool is configured by the clip portion that is fitted into the through hole of the fixing member such as the vehicle body panel, the routing tool with the binding band is provided. A wire harness or the like that is a bundled body to be bound can be advantageously fixed at a predetermined position of the vehicle. At that time, the wiring tool can be moved to a desired position on the circumference of the binding band, and the wiring tool can be stably and temporarily fixed to the desired position by the frictional resistance between the ridge portion and the band portion. Etc. can be advantageously and stably performed.

  According to the present invention, at both openings of the band portion insertion hole provided in the base portion of the routing tool of the binding band-attached routing tool, the band portion plate projects in the thickness direction of the band portion to be inserted. A ridge extending in the width direction is provided. Thereby, compared with the case where a hemispherical projection is provided in the band portion insertion hole as in the prior art and is only in point contact with the band portion, it comes into line contact with the band portion. . Therefore, since the protruding portion extending in the direction orthogonal to the moving direction of the routing tool can contact the band portion with a large area to obtain a large frictional resistance, the provisional design against the band portion of the routing tool can be obtained with a simple structure. Fixing can be realized with higher certainty than the conventional structure. In addition, since the band portion and the routing tool are not concavo-convexly fitted, it is possible to slide the routing tool in the length direction of the band portion of the binding band as in the prior art.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, FIG. 1 shows a cable tie 10 with a binding band as a first embodiment of the present invention. The linking tool 10 with a binding band is configured by inserting a routing tool 16 through a band portion 14 of a binding band 12. In the following description, “upper” means the upper side in FIG. 1, “lower” means the lower side in FIG. 1, “front” means the right side in FIG. 1, and “rear” means the left side in FIG. Shall.

  As shown in FIGS. 2 to 6, the routing tool 16 includes a base portion 20 having a band portion insertion hole 18 through which the band portion 14 of the binding band 12 is inserted, and a protrusion projecting from the base portion 20. This is configured to include a cylindrical cable holding portion 22 into which a later-described cable 74 is inserted and held. Note that the routing tool 16 is integrally formed by injection molding or the like with a synthetic resin such as polypropylene (PP) or polyamide (PA).

  The base 20 is provided with a rectangular flat plate-shaped bottom wall 24 and a top wall 26, which are substantially the same shape, arranged at positions where they overlap each other in plan view, and extend in the vertical direction at substantially four corners. (See FIG. 6). Thereby, the base portion 20 is configured with a band portion insertion hole 18 penetrating in the front-rear direction and through which the band portion 14 of the binding band 12 is inserted and held. Further, in both opening portions 30 of the band portion insertion hole 18, a length dimension that does not reach the bottom wall 24 from the upper wall 26, and the thickness direction of the band portion 14 to be inserted (in FIG. 6, perpendicular to the paper surface). A substantially flat ridge portion 32 that protrudes toward the plate width direction of the band portion 14, that is, extends over the entire length of the opening portion 30 in the width direction (left and right direction in FIG. 6). (See FIG. 6).

  On the other hand, as shown in FIG. 3, the cable holding portion 22, which is a protruding portion, extends from the front end portion 34 of the bottom wall 24 of the base portion 20 in an arc shape in a side view and extends with a dimension L <b> 1. One cylindrical forming portion 36 and a rearward end portion 38 which is the other end portion of the base portion 20 are extended in an arc shape in a side view in a longer dimension than the first cylindrical forming portion 36: L2 (L2> L1) And a second tubular forming portion 40 that extends. A cylindrical space 42 is constituted by a region surrounded by the first cylindrical forming portion 36 and the second cylindrical forming portion 40.

  As shown in FIGS. 2 to 3, an opening that opens forward is formed between the opposing surfaces of the distal end portion of the first tubular forming portion 36 and the distal end portion of the second tubular forming portion 40. 44 is defined. In addition, a stopper projection 46 that projects into the cylindrical space 42 is provided at the tip of the first cylindrical forming portion 36. The retaining protrusion 46 is formed in a flat plate shape, and is integrally connected to the distal end portion of the first cylindrical forming portion 36 at a substantially central portion on the upper surface 48 side which is one surface of the retaining protrusion 46. On the other hand, the lower surface 50 which is the other surface of the retaining protrusion 46 is inclined so as to approach a first presser plate portion 56 which will be described later as it goes inward in the cylindrical space 42.

  On the other hand, the distal end portion of the second tubular forming portion 40 is protruded into the tubular space 42 and curved downwardly in a convex shape in a side view connected to the inner wall 54 of the second tubular forming portion 40. A flat first presser plate portion 56 is provided. Further, in the vicinity of the inner wall 54 of the second tubular forming portion 40 to which the first presser plate portion 56 is connected, in a side view projecting obliquely forward and upward toward the first tubular forming portion 36. A flat plate-like second presser plate portion 58 that is convexly curved upward is provided. The second presser plate portion 58 has a free end at the tip, and can be elastically deformed in a direction away from the first presser plate portion 56. In addition, an inclined protrusion 60 that is inclined forward and obliquely upward toward the base portion 20 side is provided at the distal end portion of the second pressing plate portion 58. In the present embodiment, the base 20 (the bottom wall 24, the top wall 26), the cable holding part 22 (the first cylindrical forming part 36, the second cylindrical forming part 40, the retaining protrusion 46, the first retaining part 46). The presser plate portion 56 and the second presser plate portion 58) are both formed with the same width dimension: W (see FIG. 4).

  As shown in FIG. 1, the binding band 12 includes a band portion 14 having a long and flat plate shape with a rectangular cross section, and a head portion 62 is integrated with one end portion in the length direction of the band portion 14. Is formed. As is well known, the binding band 12 is integrally formed of a synthetic resin material, and the band portion 14 can be bent and deformed. In addition, a large number of serrated locking projections 66 are formed side by side in the longitudinal direction of the band portion 14 on one side 64 which is one side in the thickness direction of the band portion 14. On the other hand, an insertion hole 68 is formed in the head portion 62, and a locking piece 70 is provided so as to protrude into the insertion hole 68. Then, the locking piece 70 is locked to the locking protrusion 66 of the band portion 14 by bending the band portion 14 in a ring shape and inserting the tip portion into the insertion hole 68. Further, since the locking projection 66 has a sawtooth shape, the locking action of the locking piece 70 with respect to the locking projection 66 functions only in the direction in which the band portion 14 is pulled out from the insertion hole 68, and the band portion 14. Can be locked by being tightened so as not to be released.

  Next, as shown in FIG. 7, the routing tool 16 is bound and fixed to the wire harness 72 by using the routing tool 10 with a binding band having the above-described structure. More specifically, the band part 14 of the binding band 12 inserted and arranged in the band part insertion hole 18 of the routing tool 16 is wound around a predetermined position of the wire harness 72 that is a binding object and then locked to the head part 62. By doing so, the routing tool 16 can be fastened and fixed to the wire harness 72. In addition, although illustration is abbreviate | omitted, the binding band 12 after fixation cuts off the front-end | tip part of the band part 14, and can prevent a contact with another member. Further, in this state, the routing tool 16 is not concavo-convexly fitted to the band portion 14 of the binding band 12, so that it can slide on the band portion 14 of the binding band 12. It has become. In addition, although the routing tool 16 is not concavo-convexly fitted to the band portion 14, the protrusions 32 projecting from both openings 30 of the band portion insertion hole 18 of the base portion 20 have a sawtooth shape of the band portion 14. Therefore, the sliding protrusion 66 has a certain amount of sliding resistance. Therefore, the routing tool 16 is arranged at a predetermined position by sliding on the band portion 14 of the binding band 12 and the wire harness 72 (band portion) is caused by the frictional resistance against the band portion 14 of the protrusion 32. 14) It can be held at a predetermined position above.

  Finally, as shown in FIG. 8, the cable 74 is inserted and held with respect to the cable holding portion 22 of the routing tool 16 arranged and held in a desired position on the wire harness 72 in this manner. It is like that. Here, the cable 74 refers to a long covered electric wire or an optical fiber. First, as shown in FIG. 8A, the cable 74 is inserted into the opening 44 of the cable holding unit 22. At this time, the lower surface 50 of the retaining projection 46 provided at the distal end portion of the first tubular forming portion 36 is inclined so as to approach the first presser plate portion 56 toward the inside of the tubular space 42. Thus, the cable 74 can be promptly guided to the first presser plate portion 56 side in the cylindrical space 42. Here, since the extension dimension L2 of the second cylindrical forming part 40 is longer than the extension dimension L1 of the first cylindrical forming part 36, the second cylindrical forming part 40 The elastic deformation can be easily performed as compared with the first cylindrical forming portion 36. Therefore, as shown in FIG. 8B, the cable 74 can be easily inserted into the cylindrical space 42 by the second cylindrical forming portion 40 being elastically deformed. Yes. Further, when the cable 74 is pushed in the depth direction of the cylindrical space 42, the cable 74 comes into contact with the inclined protrusion 60 of the second presser plate portion 58 as shown in FIGS. Thus, the distal end portion of the second pressing plate portion 58 is surely elastically deformed toward the base portion 20 side. This advantageously prevents the cable 74 from being erroneously inserted into the cylindrical space 42 formed on the base 20 side of the second presser plate portion 58. As a result, as shown in FIG. 8D, the cable 74 inserted into the cylindrical space 42 through the opening 44 of the cable holding portion 22 is connected to the first presser plate portion 56 and the second presser foot. It is sandwiched and held between the plate portions 58.

  According to the binding band-equipped routing tool 10 having such a structure, the band portion 14 to be inserted is inserted into both openings 30 of the band portion insertion hole 18 penetrating the base portion 20 of the routing tool 16. A substantially flat protrusion 32 that protrudes in the plate thickness direction and extends over the entire length of the band portion 14 in the plate width direction, that is, the width direction of the opening 30 is provided. As a result, as compared with the conventional case where a hemispherical protrusion is provided in the band part insertion hole and is only in point contact with the band part, the protrusion 32 is formed on both the band part insertion holes 18. The opening 30 is in line contact with the band portion 14 in a direction orthogonal to the insertion direction of the band portion 14. Therefore, since the protruding portion 32 extending in the direction orthogonal to the moving direction of the routing tool 16 can contact the band portion 14 in a wide area to obtain a large frictional resistance, the routing is reliably performed with such a simple structure. The longitudinal displacement of the band portion 14 of the tool 16 can be prevented, and the temporary fixing of the routing tool 16 to the band portion 14 can be realized with higher certainty than the conventional structure. Moreover, since the band portion 14 and the routing tool 16 are not concavo-convexly fitted, it is possible to slide the routing tool 16 on the band portion 14 of the binding band 12 as in the prior art. -ing

  Next, with reference to FIGS. 9 to 10, the binding band-equipped routing tool 76 as the second embodiment of the present embodiment will be described in detail. Regarding members and parts having the same structure as the above embodiment, In the drawings, the same reference numerals as those in the above embodiment are attached, and detailed description thereof is omitted. In the present embodiment, an embodiment different from the above-described embodiment is shown in that the projecting portion projecting from the base portion 20 of the routing tool 78 is the clip portion 80.

  More specifically, as shown in FIGS. 9 to 10, the clip portion 80 includes a rectangular tube-like locking column 82 that opens on the side surface, and an arrow-like shape provided at the protruding end of the locking column 82. A pair of locking wings 84 and 84 are provided so as to be folded and projecting. Further, as shown in FIG. 10, the pair of locking wings 84, 84 spreads to the vehicle body 86 when the clip portion 80 is fitted into the through hole 88 of the vehicle body 86, which is a fixing member, for example. It is used to prevent slipping by engaging. Therefore, the wire harness 72 or the like is advantageously fixed at a predetermined position of the vehicle body 86 by binding the binding band 12 of the routing band-equipped routing tool 76 of the present embodiment to the wire harness 72 or the like to be bound. It can be done. In addition, as in the first embodiment, the routing tool 78 is moved to a desired position on the circumference of the binding band 12, and the desired resistance is applied by the frictional resistance between the routing tool 78 and the band portion 14. Since the routing tool 78 can be stably and temporarily fixed at the position, routing of the wire harness 72 and the like can be performed advantageously and stably. In FIG. 10, the vehicle body 86 and the through hole 88 are indicated by virtual lines for easy understanding.

  As mentioned above, although several embodiment of this invention has been described, this is an illustration to the last, Comprising: This invention is not limited at all by the specific description in this embodiment. For example, in the above-described embodiment, the protrusion 32 is provided over the entire length in the width direction of the opening 30, but is provided with a length that does not reach the entire length in the width direction of the opening 30. Alternatively, a plurality of openings 30 may be provided apart from each other in the width direction of the opening 30. Furthermore, in the said embodiment, although the protrusion part 32 was made into flat plate shape, as long as it does not carry out uneven | corrugated fitting to the latching protrusion 66 of the band part 14, things of arbitrary cross-sectional shapes, such as a mushroom cross-sectional shape, are used It can be adopted.
