Description

  The present invention relates to a wire harness fixing clip for fixing a wire harness to a mounting portion provided on a vehicle body.

  Conventionally, a wire harness fixing clip for fixing, for example, a wire harness connected to an ignition device of an engine of a vehicle to a plate-like mounting portion provided on a steering member which is a skeleton member for increasing the strength of the vehicle body, for example. Is known (for example, see Patent Document 1).

  The wire harness fixing clip includes an annular holding portion that holds the wire harness, and a clip body provided on the holding portion. When fixing the wire harness to the attachment portion, the clip body is coupled to the attachment portion while the wire harness is held by the holding portion. Thereby, a wire harness is fixed to an attaching part via the clip for wire harness fixation.

  However, the wire harness fixed to the attachment portion may bend toward the attachment portion according to the wiring path, for example, and interfere with the edge portion of the attachment portion. For this reason, for example, when the wire harness is repeatedly rubbed against the edge portion of the attachment portion by vibration applied during traveling of the vehicle, the wire harness is damaged by the frictional force generated between the wire harness and the edge portion of the attachment portion.

Therefore, in order to prevent the wire harness from interfering with the edge of the attachment portion, it is conceivable to attach a dedicated protective member for protecting the wire harness to the wire harness separately from the wire harness fixing clip. . According to this, the protective action of the protective member prevents the wire harness bent toward the attachment portion from interfering with the edge portion of the attachment portion, so that the wire harness is damaged due to interference with the edge portion of the attachment portion. Can be prevented.
JP 2000-115964 A (page 3-4, FIG. 1)

  However, in order to prevent the wire harness from interfering with the edge of the mounting portion, it is necessary to attach the protective member dedicated to the wire harness separately from the wire harness fixing clip, which increases the number of parts and the number of construction steps. However, the manufacturing cost and the construction time are increased.

  Then, the objective of this invention is providing the clip for wire harness fixation which can prevent interference of the wire harness to the edge part of an attaching part, without causing the increase in manufacturing cost and construction time.

  In order to solve the above-described problem, the invention according to claim 1 is a wire harness fixing clip for fixing a wire harness connected to an electric device mounted on a vehicle to an attachment portion provided on a vehicle body. An annular holding portion for holding the wire harness, and a clip main body provided on the holding portion and coupled to the attachment portion, and the attachment portion includes the attachment portion. An interference preventing member is provided for preventing the wire harness held by the holding portion from interfering with an edge portion of the mounting portion when the clip main body is coupled to the mounting portion.

  The invention according to claim 2 is the invention according to claim 1, wherein the interference preventing member is made of a flexible plate-like member and extends along the wire harness held by the holding portion, and The holding portion is formed so as to be disposed between the wire harness and the attachment portion in a state where the clip main body is coupled to the attachment portion.

  According to a third aspect of the present invention, in the first aspect of the present invention, the attachment portion has a plate shape, and the clip main body is provided on an outer peripheral surface of the holding portion and is inserted into the holding portion. A plate-like base that extends along the insertion direction of the wire harness, a column that rises from the base toward the outside of the holding part, passes through the attachment part through an opening formed in the attachment part, and Extending from the tip of the column part to the edge of the opening on the surface of the mounting part opposite to the surface facing the holding part, the distance from the pillar part is gradually increased and the tip of the opening is extended. A pair of elastically deformable locking claws locked to the edge portion, and the interference prevention member is made of a flexible plate-like member, and is attached to the wire harness held by the holding portion. The clip body extending along and to the mounting portion As in a bound form is disposed between the wire harness and the mounting portion, characterized in that it is formed in the base.

  According to a fourth aspect of the present invention, in the invention of the first to third aspects, the clip body is locked to the mounting portion so as to temporarily fix the wire harness held by the holding portion to the mounting portion. A possible hook is formed.

  According to the structure of Claim 1, the wire harness hold | maintained at the holding | maintenance part to the holding | maintenance part for hold | maintaining a wire harness, or an attachment part is combined with the attachment part. Because interference prevention members are provided to prevent interference with the edge of the mounting part in the state, even if the wire harness is bent toward the mounting part according to the wiring route, the wire harness is attached. Interference with the edge of the part is prevented. Therefore, it is possible to prevent the conventional wire harness from being damaged due to the wire harness interfering with the edge of the mounting portion.

  In addition, since the interference prevention member is provided in the holding part of the clip for fixing the wire harness or the clip main body, a conventional protective member is used to prevent the interference of the wire harness to the edge of the attachment part. Since it is not necessary to attach to the wire harness separately from the harness fixing clip, it is possible to reduce the number of parts and the number of construction steps as compared with the conventional case, and thus it is possible to reliably suppress the increase in manufacturing cost and construction time. .

  According to the configuration described in claim 2, the interference preventing member can be configured by a flexible plate-like member, and extends along the wire harness held by the holding portion and is clip body to the mounting portion. It can form in a holding part so that it may be arranged between a wire harness and an attaching part in the combined state.

  According to the configuration described in claim 3, the interference preventing member can be formed of a flexible plate-like member, extends along the wire harness held by the holding portion, and the clip main body to the attachment portion. The clip body can be formed at the base of the clip body so as to be disposed between the wire harness and the mounting portion.

  According to the configuration of the fourth aspect, since the clip body is formed with a hook that can be locked to the mounting portion so as to temporarily fix the wire harness held by the holding portion to the mounting portion. If the wire harness is temporarily fixed to the mounting part before the electrical equipment to which the wire harness is connected is mounted on the vehicle in the manufacturing factory, a dedicated member for temporary fixing is provided separately from the wire harness fixing clip. The wire harness can be temporarily fixed to the mounting portion without using it. Thereby, the increase in the manufacturing cost by manufacturing the member only for temporary fixation separately from the clip for wire harness fixation can be suppressed reliably.

  The present invention will be described with reference to the illustrated embodiments.

  FIG. 1 shows a wire harness fixing clip 11 according to the present invention for fixing a wire harness 10 connected to an ignition device of an engine (not shown) of a vehicle to a steering member (not shown) provided at the front of the vehicle. An applied example is shown. As is well known in the art, the steering member is a skeleton member that extends along the vehicle width direction and increases the rigidity of the front portion of the vehicle.

  The steering member is provided with an attachment portion 13 for attaching the wire harness fixing clip 11. The attachment portion 13 has a plate shape, and in the illustrated example, is provided on the steering member so as to protrude from the steering member toward the front of the vehicle. An opening 14 formed so as to penetrate the mounting portion 13 in the thickness direction of the mounting portion is formed.

  As shown in FIG. 1, the wire harness fixing clip 11 according to the present invention includes an annular holding portion 15 for holding the wire harness 10, and a clip body provided on the holding portion and coupled to the attachment portion 13. 16.

  In the example shown in the figure, the holding portion 15 is composed of an insulation lock band 17. As is well known in the art, the insulation lock band 17 is a bundling member formed of an elastic resin material such as polypropylene, and is provided at an elongated band portion 18 and one end 18a of the band portion. It has a cylindrical insertion portion 19 that allows insertion. A plurality of protrusions 20 are formed on one surface of the band 18 along the longitudinal direction of the band 18. The insertion part 19 has a locking part (not shown) that can be locked to each protrusion 20 of the band part when the band part 18 is inserted into the insertion part. The locking portion has a locking function that allows movement of the band portion 18 in the insertion portion 19 in the insertion direction and prevents movement of the band portion 18 in the direction opposite to the insertion direction. The insulation lock band 17 is formed in an annular shape by inserting the band portions 18 into the respective insertion portions 19, and the tightening amount to the wire harness can be adjusted in a state where the wire harness 10 is inserted inward.

  The clip main body 16 includes a plate-like base portion 21 provided in the belt portion 18 of the insulation lock band 17 and a column portion 22 rising from the base portion toward the outside of the insulation lock band 17 that forms an annular shape.

  In the illustrated example, the base portion 21 has a rectangular plane, and the base portion 21 is provided in the belt portion so that the longitudinal direction thereof is orthogonal to the longitudinal direction of the belt portion 18 of the insulation lock band 17. That is, the base 21 is disposed so as to extend along the extending direction of the wire harness 10 held by the insulation lock band 17. A pair of edge portions 21a facing each other in the longitudinal direction of the base portion 21 is provided with a leaf spring portion 23 that can be elastically deformed.

  In the illustrated example, each leaf spring portion 23 is formed integrally with the base portion 21, and extends from each edge portion 21 a of the base portion 21 in the rising direction of the column portion 22 while gradually increasing the interval. Each leaf spring portion 23 is elastically deformed so that each tip 23a abuts on the attachment portion 13 and the distance between the attachment portions 13 increases toward the attachment portion 13 when the clip body 16 is coupled to the attachment portion 13. (See FIG. 2).

  The column portion 22 of the clip body 16 has a length that allows the attachment portion 13 to pass through the opening 14 from one side thereof (the upper side of the attachment portion 13 when viewed in FIG. 1) through the opening 14. In the illustrated example, the column portion 22 is formed integrally with the base portion 21.

  Furthermore, the clip body 16 includes a pair of elastically deformable locking claws 24. As shown in FIG. 3, the locking claws 24 extend from the tip end 22 a of the column portion 22 toward the edge portion 14 a of the opening 14 of the attachment portion 13 while gradually increasing the interval therebetween. Each locking claw 24 is formed integrally with the column portion 22 in the illustrated example. The clip main body 16 is coupled to the mounting portion 13 by the locking claws 24 being locked from the other side of the mounting portion 13 to the edge portion 14a of the opening 14 at the tip 24a.

  When the wire harness 10 is fixed to the attachment portion 13, the wire harness 10 is held by tightening the wire harness 10 with the belt portion 18 of the insulation lock band 17, and then the locking claws 24 of the clip body 16 are opened to the opening of the attachment portion 13. The clip body 16 is pushed into the opening 14 so as to be pressed against the edge 14 a of the 14. At this time, as described above, each locking claw 24 can be elastically deformed, so that when pressed against the edge portion 14a of the opening 14, each tip 24a bends so as to approach the column portion 22. . Thereby, each latching claw 24 can get over the edge portion 14 a of the opening 14 as the clip body 16 is pushed into the opening 14. When each of the locking claws 24 gets over the edge portion 14a of the opening 14, it returns to an unloaded state due to its elastic reaction force, and from each other side of the mounting portion 13 to the edge portion 14a of the opening 14 at each tip 24a. Locked. Thus, when a pulling force is applied to the clip body 16 in the direction of withdrawal from the opening 14, each locking claw 24 is received by the edge portion 14 a of the opening 14, so that the clip body 16 is not pulled out from the opening 14. Be blocked.

  Thereby, the wire harness fixing clip 11 is coupled to the attachment portion 13, and the wire harness 10 held by the insulation lock band 17 is fixed to the attachment portion 13 via the wire harness fixing clip 11.

  In the state in which the clip body 16 is coupled to the mounting portion 13, as described above, the leaf spring portions 23 are elastically deformed so that the distance between them is widened toward the mounting portion 13. The spring force acts in the direction of pulling out the column portion 22 from the opening 14 from each leaf spring portion 23. Thereby, in the coupling state of the clip main body 16 to the attachment portion 13, the edge portion 14 a of the opening 14 is sandwiched between each locking claw 24 and each leaf spring portion 23. The rattling between 13 is more reliably prevented.

  The wire harness fixing clip 11 according to the present invention prevents the wire harness 10 held by the insulation lock band 17 from interfering with the edge portion 13a of the attachment portion 13 when the clip body 16 is coupled to the attachment portion 13. The interference prevention member 25 is provided.

  As shown in FIGS. 1 and 2, the interference preventing member 25 is a plate-shaped member having a rectangular plane and having flexibility. At the center of the interference preventing member 25, an opening 26 that allows the base portion 21 of the clip body 16 and each leaf spring portion 23 to pass is formed so as to extend along the longitudinal direction of the interference preventing member 25. The interference preventing member 25 is disposed so as to surround the base portion 21 and each leaf spring portion 23 so that the longitudinal direction thereof coincides with the longitudinal direction of the base portion 21 and the base portion 21 and each leaf spring portion 23 are exposed from the opening 26. ing. Thereby, the interference prevention member 25 extends along the extending direction of the wire harness 10 between the wire harness 10 held by the insulation lock band 17 and the attachment portion 13 in a state where the wire harness 10 is fixed to the attachment portion 13. Are arranged as follows. The length of the interference preventing member 25 is set to a length in which both end portions 25a protrude from the both edge portions 13a of the mounting portion 13 to the outside of the mounting portion 13 when the clip body 16 is coupled to the mounting portion 13. ing. In the illustrated example, the interference prevention member 25 is formed integrally with the band portion 18 of the insulation lock band 17.

  For example, when the wire harness 10 is bent toward the mounting portion 13 while being held by the insulation lock band 17 as shown in FIG. 3 according to the wiring path of the wire harness 10, the interference preventing member 25 is as described above. Moreover, since the wire harness 10 extends along the extending direction of the wire harness 10 between the wire harness 10 held by the insulation lock band 17 and the attachment portion 13, the wire harness is bent toward the attachment portion 13. The interference preventing member 25 is bent and deformed toward the mounting portion 13 by the pressing force received from 10 toward the mounting portion 13. At this time, as described above, since the opening 26 formed in the interference prevention member 25 has a size that allows the base 21 and the plate spring portions 23 to be inserted, the interference prevention member 25 toward the attachment portion 13 can be provided. The bending deformation is not hindered by the base portion 21 and each leaf spring portion 23. Further, as described above, the length of the interference prevention member 25 is set such that both end portions 25 a protrude from both edge portions 13 a of the attachment portion 13, so that the interference prevention member 25 moves to the attachment portion 13. The edge portion 13a of the attachment portion 13 is partially covered with the end portion 25a of the interference preventing member 25 by being bent and deformed toward the surface. This prevents the wire harness 10 bent toward the attachment portion 13 from interfering with the edge portion 13 a of the attachment portion 13.

  Thus, since the wire harness 10 is prevented from interfering with the edge portion 13a of the attachment portion 13 by the interference preventing member 25 provided in the belt portion 18 of the insulation lock band 17 for holding the wire harness 10. For example, even if the wire harness 10 is bent toward the attachment portion 13 according to the wiring path of the wire harness 10, the wire harness 10 can be prevented from interfering with the edge portion 13 a of the attachment portion 13.

  Therefore, it is possible to prevent the conventional wire harness 10 from being damaged due to the wire harness 10 interfering with the edge portion 13a of the attachment portion 13.

  Further, as described above, since the interference preventing member 25 is provided in the band portion 18 of the insulation lock band 17, in order to prevent the wire harness 10 from interfering with the edge portion 13a of the mounting portion 13, as in the conventional case. Since it is not necessary to attach a protective member to the wire harness 10 separately from the wire harness fixing clip 11, the number of parts and the number of construction steps can be reduced as compared with the conventional case, and therefore the manufacturing cost and the construction time are increased. It can be surely suppressed.

  In the present embodiment, the example in which the interference preventing member 25 is provided in the band portion 18 of the insulation lock band 17 is shown, but instead, for example, as shown in FIG. 21 can be provided on a pair of leaf spring portions 23 provided on the plate 21.

  In the example shown in FIG. 4, the interference preventing member 25 includes a pair of wing members 27 provided at the tip 23 a of each leaf spring portion 23. Each wing member 27 is provided at the distal end 28 a of the extension portion 28 extending in parallel to the base portion 21 in a direction away from the central portion of the distal end 23 a of each leaf spring portion 23, and orthogonal to the longitudinal direction of the base portion 21. And a plate-like plate portion 29 arranged in parallel to the base portion 21, and each of the extension portion 28 and the plate portion 29 forms a T shape as a whole. The length dimension of each extending portion 28 and the width dimension of each plate portion 29 are determined so that each plate portion 29 is entirely or partially separated from both edge portions 13 a of the attachment portion 13 in a state where the clip body 16 is coupled to the attachment portion 13. Each is set so as to protrude.

  According to the configuration shown in FIG. 4, when the wire harness 10 is bent toward the attachment portion 13 while being held by the insulation lock band 17, the extending portion 28 of each wing member 27 is attached according to the bending of the wire harness 10. It is bent and deformed toward the portion 13. Thereby, since the edge 13a of the attachment part 13 is partially covered with the plate part 29 of the wing member 27, the wire harness 10 is prevented from interfering with the edge 13a of the attachment part 13.

  For example, in the configuration shown in FIG. 4, as shown in FIG. 5, the wire harness 10 is temporarily attached to the attachment portion 13 on one edge portion 21 b of a pair of edge portions different from the respective edge portions 21 a of the base portion 21. A hook 30 for fixing can be provided. The hook 30 is provided on the one edge portion 21 b of the base portion 21 so as not to prevent the insertion of the wire harness 10 into the insulation lock band 17 and the coupling of the clip body 16 to the attachment portion 13. In the illustrated example, the hook 30 includes a protruding portion 31 protruding from the one edge portion 21b, and a locking portion 32 formed at a tip 31a of the protruding portion. The locking portion 32 can be locked to the edge portion 14 a of the opening 14 of the attachment portion 13.

  For example, in a vehicle manufacturing factory, before the ignition device to which the wire harness 10 is connected is mounted on the vehicle, the wire harness 10 is brought into contact with or caught on a component (not shown) provided on the vehicle. In order to prevent damage or disconnection of the wire 10, it is necessary to temporarily fix the wire harness 10 to the mounting portion 13.

  For this reason, conventionally, although not shown, the wire harness 10 is packed into a bag, or a band member is wound around the wire harness 10 and the hook member is hooked on the band member. Although it was hung, it is necessary to manufacture a temporary fixing dedicated member such as the bag, the band member, and the hook member separately from the wire harness fixing clip 11, which increases the manufacturing cost. .

  On the other hand, according to the example shown in FIG. 5, since the hook for temporarily fixing the wire harness 10 to the mounting portion 13 is formed on the base portion 21 of the clip body 16 as described above, the wire harness fixing The wire harness 10 held by the insulation lock band 17 can be temporarily fixed to the attachment portion 13 without using a conventional temporary fixing dedicated member separately from the clip 11. Thereby, the increase in the manufacturing cost by manufacturing the member only for temporary fixation separately from the clip 11 for wire harness fixation can be suppressed reliably. In the example shown in FIG. 5, the example in which the hook 30 is provided on the base portion 21 is shown, but instead, the hook 30 can be provided on a portion other than the base portion 21 of the clip body 16.

  Further, in the present embodiment, an example in which the insulation lock band 17 is used for the holding portion 15 for holding the wire harness 10 has been shown, but instead, for example, a hose band-like binding whose inner diameter can be adjusted by a worm gear system. A member can be used for a holding part.

  Furthermore, in the present embodiment, the example in which the present invention is applied to fix the wire harness 10 connected to the ignition device of the engine to the mounting portion 13 provided in the steering member is shown. A wire harness connected to an in-vehicle device other than the engine ignition device is fixed to an attachment portion provided on a skeleton member other than the steering member or an attachment portion provided on a vehicle body constituent member other than the skeleton member. The present invention can be applied to.
