Description

  The present invention relates to a band clip and a wire harness including the same.

  Conventionally, a band clip is used to route a wire harness in a vehicle. A conventional general band clip has a band body and a clip body. The band main body includes a band portion and a band portion fixing portion that fixes the base end of the band portion and locks the distal end side. The clip main body includes a dish part integral with the band part fixing part, a column part integral with the dish part, and an anchor part integral with the column part.

  The band clip configured as described above cannot be applied because the anchor portion does not reach the mounting hole at a location where the separation distance from the mounting hole of the support panel to the wire bundle is large.

  Specifically, in the wiring route of the wire bundle in the vehicle, the height level of the part having the mounting hole of the support panel falls more greatly than the height level of the other part offset in the wiring direction. There is a place. In other words, the distance from the support panel to the wire bundle is large at the position of the support panel mounting hole, and the distance from the support panel mounting hole to the wire bundle is small at the position offset from the support panel mounting hole. It is in. When the conventional general band clip is applied to the mounting hole in this situation and the anchor portion is brought closer, the position offset from the position held by the band main body in the wire bundle is in the middle of the approach. Will first abut against the part offset from the mounting hole. For this reason, an anchor part does not reach an attachment hole and the conventional band clip cannot be applied.

  In the above case, conventionally, for example, a band clip shown in Patent Document 1 can be applied. The band clip 36 shown in FIG. 7 has substantially the same configuration as that shown in Patent Document 1, and the band main body 37 and the clip main body 38 are offset in the horizontal direction and relatively relative to the vertical direction. It is slidably connected.

  The band clip 36 has a wire bundle 33 in which the branch line 35 extends upward from the trunk line 34 and the trunk line 34 has a large diameter portion 34a and a small diameter portion 34b. This is applied when it is necessary to route the cable so that the distance from the support panel 31 to the wire bundle becomes small. That is, the band clip 36 holds the electric wire bundle 33 by the band main body 37 at a position corresponding to the large diameter portion 34a, and the clip main body 38 is attached to the mounting hole 32 provided at a position corresponding to the small diameter portion 34b. The band main body 37 side is mounted so as to be pushed down relative to the clip main body 38 side.

Japanese Patent Laying-Open No. 2015-53783

  However, in the technique described in Patent Document 1, the band main body 37 is offset from the clip main body 38 in the horizontal direction, and has a cantilever structure that is slidably connected only on one side surface of the slide connecting portion. It was. For this reason, in order to cope with the difference in height level (step) between the mounting hole 32 of the support panel and the wire bundle 33 to be routed, when the band body 37 is pushed down and slid downward at the slide connecting portion, There was a concern that excessive stress was concentrated on the anchor portion and the anchor portion was damaged. There is also a problem that the band main body 37 and the clip main body 38 are separated by exceeding the stroke limit due to the operation of pushing down the band main body 37. Furthermore, as the band main body 37 is pushed down, the engagement area at the slide connecting portion is reduced, so that it is difficult to secure the holding force at the slide connecting portion.

  The present invention has been made to solve the above-described problems, and it is difficult for components to be damaged or separated when a wire bundle is routed on a support panel having a step having a low mounting hole. And it aims at providing the band clip which improved the retention strength of the connection part, and a wire harness provided with the same.

  In order to achieve the above object, a band clip according to the present invention includes a band unit wound around a wire bundle and a band unit fixing unit that fixes a base end of the band unit and locks a distal end side. A clip main body that is locked to the mounting hole of the support panel by the anchor portion and the dish portion, and a connection portion that connects the band main body and the clip main body and that can change a connection length. The portion includes a fixing block provided integrally with the dish portion, and a slide block formed integrally with the band portion fixing portion, in which a concave portion into which the fixing block is fitted is formed, and the fixing The block is formed with a plurality of ridge portions parallel to each other on both side surfaces, and the slide block is a groove portion that engages with the ridge portions on the inner surface of the recess corresponding to the both side surfaces of the fixed block. Formed, The concave portion and the Kitotsu ridge portion, the slide block is deeply fitted to the opposite direction can be slid in a direction to the fixed block is configured to engage impossible slide.

  With this configuration, the wire body is held by the band body with the slide block being pulled out from the fixed block to the maximum, the anchor portion is locked to the mounting hole of the support panel, and the slide block is pushed down, so that the desired The electric wire bundle can be held at the height position. That is, as the slide block is pushed down, the engagement area between the slide block and the fixed block increases, so that it is easy to ensure the holding force at the connecting portion. In addition, since the ridges are formed on both side surfaces of the fixed block and are configured to engage with the ridges on the slide block side, as described in Patent Document 1, it is cantilevered only on one side. The holding force at the connecting portion is improved as compared with the configuration in which the slide is connected. Moreover, since the band main body and the slide main body are not offset in the horizontal direction, stress does not concentrate on the anchor portion. Thereby, when performing the wiring work of the wire bundle on the support panel having a step, the possibility that the clip body is damaged can be reduced. Moreover, in the wire bundle routing operation, the slide block is pushed down and slides in the direction of deeply fitting into the fixed block, so that the band main body and the clip main body are not separated by the routing operation.

  In addition, a first lock portion is formed on an upper portion of another side surface of the fixed block, and the first lock portion is formed on an inner surface lower portion of the concave portion of the slide block corresponding to the first lock portion of the fixed block. It is good also as a structure in which the 2nd lock part latched releasably was formed.

  With this configuration, the slide block is held in a releasable state in a state where the slide block is pulled out from the fixed block to the maximum extent. Thereby, it is possible to prevent the slide block from slipping out of the fixed block and sliding in the direction in which the slide block is deeply fitted into the fixed block before the wire bundle routing operation.

  The wire harness according to the present invention includes an electric wire and the band clip, and the electric wire is held by the band main body of the band clip.

  According to the present invention, there is provided a band clip in which parts are not easily damaged or separated when a wire bundle is routed on a stepped support panel having a low mounting hole, and the holding power of the connecting portion is improved. The wire harness provided with can be provided.

And. The anchor portion 21 has a slightly larger diameter at the rear end than the attachment hole 4, and when inserted into the attachment hole 4, the outer peripheral portion can be elastically deformed to pass through the attachment hole 4. It hits the periphery of the hole 4 so that it cannot come out. The dish portion 23 is on the side opposite to the anchor portion 21, and the outer edge portion abuts against the support panel 3 to support the clip body 20.

  The connection part 26 connects the band main body 10 and the clip main body 20, and has a configuration in which the connection length can be changed. The connection length refers to the length of the connection portion 26 in the vertical direction. Since the connection length can be changed, the distance from the clip body 20 to the band body 10 can be adjusted.

  The connecting portion 26 is formed of a resin fixed block 24 provided integrally with the plate portion 23 and a recess 16 into which the fixed block 24 is fitted, and is formed of resin formed integrally with the band portion fixing portion 12. And a slide block 14. By changing the depth of fitting between the fixed block 24 and the slide block 14, the connection length can be changed.

  Specifically, the fixed block 24 is formed with a plurality of ridges 25 parallel to each other on both side surfaces 24a, 24a. Further, the slide block 14 is formed with a concave strip portion 15 that engages with the convex strip portion 25 on the inner surface of the concave portion 16 corresponding to each of the both side surfaces 24 a and 24 a of the fixed block 24.

  The fixed block 24 is a rectangular parallelepiped block having the same width as the plate portion 23 (width in the Y direction in FIG. 3A). This width of the fixed block 24 may be narrower or wider than the width of the dish portion 23 depending on the holding force required for the connecting portion 26.

  The slide block 14 has a recess 16 in which the fixed block 24 is fitted. Specifically, the slide block 14 has a rectangular parallelepiped recess 16 into which a rectangular parallelepiped block of the fixed block 24 can be fitted with a gap fit.

  Further, the protruding strip portion 25 on the fixed block 24 side and the concave strip portion 15 on the slide block 14 side are slidable in a direction in which the slide block 14 is deeply fitted into the fixed block 24 and cannot slide in the opposite direction. Configured to match.

  As shown in FIG. 3 (b), the plurality of ridge portions 25 on the fixed block 24 side have a substantially saw-toothed cross section with a tooth tip pointing downward. Specifically, each ridge portion 25 constitutes one peak of a sawtooth by a substantially horizontal surface 25a and an inclined surface 25b.

  As shown in FIG. 5B, the plurality of concave strips 15 on the slide block 14 side have a shape corresponding to the plurality of convex strips 25 having a substantially sawtooth cross section on the fixed block 24 side. Specifically, each concave strip 15 is configured such that one peak of a sawtooth fits between a substantially horizontal surface 15a and an inclined surface 15b.

  In the direction in which the slide block 14 is deeply fitted into the fixed block 24, the protruding strip 25 on the fixed block 24 side slides the inclined surface 25b on the inclined surface 15b of the concave strip 15 on the slide block 14 side. It can be slid by getting over it. On the other hand, in the opposite direction, the ridge 25 on the fixed block 24 side is in a state of abutting the substantially horizontal surface 25a against the substantially horizontal surface 15a of the recess 15 on the slide block 14 side. It cannot be slid.

  In this embodiment, although the cross-sectional shape of the protruding item | line part 25 and the recessed item part 15 is a substantially sawtooth shape, a shape is not limited to this. Any cross-sectional shape can be used with the tooth tip facing downward. In short, any cross-sectional shape can be used as long as the slide block 14 can slide in a direction that fits deeply into the fixed block 24 and cannot slide in the opposite direction. It may be.

Next, a configuration for locking the slide block 14 in a state where it is pulled out from the fixed block 24 to the maximum will be described.
As shown in FIG. 3B, a first lock portion 28 is formed on the upper portion of another side surface 24 b of the fixed block 24. Further, as shown in FIG. 5 (b), the second lock that is releasably locked to the first lock portion 28 at the lower part of the inner surface of the concave portion 16 of the slide block 14 corresponding to the first lock portion 28 of the fixed block 24. A portion 18 is formed.

  Specifically, the first lock portion 28 on the fixed block 24 side has two convex portions provided at predetermined intervals in the vertical direction, and the second lock portion 18 on the slide block 14 side has the first lock portion. It is one convex part latched in the concave part between the two convex parts of the part 28. FIG. Further, the first lock portion 28 may be two convex portions, and the second lock portion 18 may be one convex portion. Before the anchor portion 21 is locked to the mounting hole 4 of the support panel 3, the slide block 14 is pulled out from the fixed block 24 to the maximum extent. At this time, the convex portion of the second lock portion 18 on the slide block 14 side is fitted into the concave portion between the two convex portions of the first lock portion 28 on the fixed block 24 side to lock the state. . That is, the slide block 14 is prevented from coming out of the fixed block 24, and the slide block 14 is prevented from sliding in the direction of deeply fitting into the fixed block 24. When a predetermined external force acts downward on the slide block 14 in the locked state, the convex portion of the second lock portion 18 gets over the convex portion of the first lock portion 28 and can slide downward.

  The wire harness W according to the present embodiment of the present invention includes the wire bundle 2 and the band clip 1 described above, and the wire bundle 2 is held by the band main body 10 of the band clip 1.

Next, a method for routing the wire bundle 2 to the support panel 3 having a step using the band clip 1 according to the present embodiment will be described.
6A shows a state before the anchor portion 21 is inserted into the mounting hole 4 of the support panel 3, and FIG. 6B shows a state where the slide block 14 is pushed down after the insertion.

  First, as shown in FIG. 6A, before the attachment to the support panel 3, the band clip 1 is in a state in which the slide block 14 is pulled out to the fixed block 24 at the maximum at the connecting portion 26 under the action of the required external force. That is, the connection length is in the longest state. Further, the wire bundle 2 is held by the band portion 11.

  Next, as shown in FIG. 6B, the clip body 20 is locked in the mounting hole 4 of the support panel 3. At this time, the wire bundle 2 is not yet in contact with the high step portion of the support panel 3. Next, by pushing down the wire bundle 2, the slide block 14 slides in a direction in which the slide block 14 is fitted into the fixed block 24. The slide block 14 is slid into the fixed block 24 until the wire bundle 2 comes into contact with the high step portion of the support panel 3. In this way, the wiring step of the wire bundle 2 is eliminated within a range in which the slide block 14 can slide.

Next, functions and effects will be described.
As described above, in the band clip 1 according to the embodiment of the present invention, the electric wire bundle 2 is held by the band body 10 in a state where the slide block 14 is pulled out from the fixed block 24 to the maximum, and the anchor portion 21 is supported by the support panel. 3 to the mounting hole 4. Thereafter or simultaneously, the electric wire bundle 2 can be held at a desired height position by pushing down the slide block 14. As the slide block 14 is pushed down, the engagement area between the slide block 14 and the fixed block 24 increases, so that it is easy to ensure a sufficient holding force at the connecting portion 26.

  Further, since the convex strips 25 are formed on the both side surfaces 24a and 24a of the fixed block 24 and are configured to engage with the concave strips 15 on the slide block 14 side, as described in Patent Document 1, 1 is used. The holding force at the connecting portion 26 is improved as compared with the configuration in which the slide connection is performed in a cantilever manner only on the side surface.

  Moreover, since the band main body 10 and the clip main body 20 are not offset in the horizontal direction, stress does not concentrate on the anchor portion 21. Thereby, when performing the wiring operation | work of the wire bundle 2 with respect to the support panel 3 with a level | step difference, possibility that the clip main body 20 will be damaged can be reduced.

  Moreover, in the wiring work of the wire bundle 2, the slide block 14 is pushed down and slides in the direction of deeply fitting into the fixed block 24, so that the band main body 10 and the clip main body 20 may be separated in the wiring work. Absent.

  Before the wire bundle 2 is routed, the slide block 14 is pulled out from the fixed block 24 as much as possible, but this state can be released by locking the second lock portion 18 to the first lock portion 28. It is locked to. As a result, before the wire bundle 2 is routed, the slide block 14 does not come out of the fixed block 24, and the slide block 14 may accidentally slide in the direction of deeply fitting into the fixed block 24. Can be prevented.

  In addition, the wire harness W according to the present embodiment includes the wire bundle 2 and the band clip 1, and is configured to hold the wire bundle 2 by the band body 10 of the band clip 1. This produces the same effect as the above effect.

  The present invention has the effect that when connecting a wire bundle to a support panel having a step where the location of the mounting hole is low, the parts are hardly damaged or separated and the holding power of the connecting portion is improved. It is useful for a band clip and a wire harness provided with the same.
