Has been. Further, in the natural state, both the bellows portions are expanded and deformed into an inverted C shape as shown in FIGS. 1 and 2, and the both locking claws 19a and 19a are held close to each other.

  On the other hand, the extruding portion 16 is formed in substantially two flat plate shapes, and a space portion 16a that secures inward elastic deformation is formed in the center of the inside. , 19 are located directly above the locking claws 19a, 19a. The extrusion portion 16 is integrally provided with protrusions 16b and 16 that are engaged with the concave portion of the bellows portion when the leg pieces 19 and 19 are inserted into the fixing holes 3a on both outer surfaces. On both sides, convex portions 16c and 16c that push the both locking claws 19a and 19a open are provided.

  Hereinafter, the operation of the present embodiment will be described.

  First, in order to attach a wire harness fastener to the fixing hole 3a of the vehicle body panel 3, as shown in FIG. 1, the leg pieces 19, 19 of the clip 2 are held from the locking claws 19a, 19a by holding the fastener body 1. When the fastener body 1 is pushed down as it is against the outer hole edge of the fixing hole 3a, as shown in FIG. 3, the distal end portion of the push-out portion 16 enters between the bellows portions and the locking claws 19a, 19a, and both legs. The leg pieces 19, 19 as a whole enter the fixing hole 3 a in order from the locking claws 19 a, 19 a while spreading the pieces 19, 19.

  At this time, the connecting pieces 18 and 18 are deformed into a flat shape following the shape of the upper surface of the vehicle body panel 3, and the support legs 17 and 17 are also crushed and deformed by pressing part of the upper surface on the lower surface of the base portion 4.

  In this state, on the fastener body 1 side, both supports 5 and 5 are elastically deformed in the diameter increasing direction and the opening 10 is opened, and the upper end of the holding part 7 is also open. A plurality of (in this case, eight) wire harnesses H are collectively inserted into the holding portion 7 from the opening 10.

  Next, when the fingers 5d and 5d of the supports 5 and 5 are grasped with two fingers of one hand and the supports 5 and 5 are deformed in the diameter-reducing direction, as shown in FIG. 5b and 5b are overlapped with each other, and the locking claw 6b engages in the locking groove 6a and is engaged in a resilient state, and the both 5 and 5 are connected and locked.

  At this time, along with the inward deformation of the supports 5, 5, as shown in FIG. 4, the end edge of the support protrusion 12 comes into contact with the opposing contact surface 13 and ends of the holding portion 7. The parts 7b and 7b are brought into contact with each other. At the same time, both the support arms 8 and 8 rotate outwardly so that the one end portions 8a and 8a are pushed and opened from each other with the other end portions 8b and 8b being fixed ends as fulcrums. 9 end edges 9a, 9a move in the abutting direction to press both side portions of the holding portion 7 in a direction close to each other. For this reason, the holding part 7 is elastically deformed so as to be reversed inward from the vicinity of both side parts, becomes an inverse Ω shape, and closes the opening 10 side. As a result, the entire wire harness H is held in an enclosed state on the rhombus-shaped bottom portion 7 a side of the holding portion 7.

  At this time, since the fastener body 1 is slightly lifted, on the clip 2 side, as shown in FIG. 4, the support legs 17 and 17 and the connecting pieces 18 and 18 are restored to their original shapes, and both The pawls 19a, 19a are pushed outward by the both convex portions 16c, 16c of the pushing portion 16 and are locked to the lower hole edge of the fixing hole 3a.

  As described above, in the present embodiment, when the supports 5 and 5 are connected and locked by the lock mechanism 6, the holding portion 7 clamps the entire wire harness H by the support arms 8 and 8 and the protrusions 9 and 9. Since it is wrapped in a state and held in a bundled state, the wire harness H can be securely and firmly held. Therefore, even if the atmospheric temperature of the vehicle body becomes high, it is possible to stably hold each wire harness H for a long period without the support members 5 and 5 being deformed and separated.

  In particular, by holding each wire harness H in a bundled state, an outward reaction force (resistance force) is generated from each wire harness H, and the support arms 8 and 8 and the protrusions 9 and 9 against the reaction force are generated. Since the holding force increases, the holding force increases.

  In addition, since both the supports 7 and 7 can be locked with one touch, the work of fastening the wire harness H becomes extremely easy, and the work efficiency can be improved.

  Further, in the present embodiment, the work for reducing the diameter of both the supports 5 and 5 is performed by the two finger-hanging portions 5d and 5d, so that this work can be easily performed.

  Further, as described above, the opening portion 10 side of the holding portion 7 is closed by both protrusions 9 and 9 so that the entire wire harness H is surrounded on the bottom portion 7a side of the holding portion 7 so that the wire harness H is It becomes possible to hold more securely and firmly.

  In particular, the support arms 8 and 8 are pressed so as to sandwich both side portions of the holding portion 7 on the bottom portion 7a side, and the wire harness H in the holding portion 7 is directly sandwiched. Holding power increases. Therefore, the wire harness H can be automatically and securely held firmly.

  Further, both the outer support 7 and the upper support 7, as shown by the arrows in FIG. 4, are fixed to each support 7, 7 by the firm engagement between the locking groove 6 a and the locking claw 6 b of the lock mechanism 6. Even if a pulling force is applied, a reliable locked state can be obtained. In particular, in a state in which the supports 5 and 5 are locked, the support protrusion 12 elastically contacts the contact surface 13 and opens in the locking groove 6a and the lock claw 6b in the direction of opening (the direction of the small arrow in FIG. 4). Since the force acts, the locking force between the locking groove 6a and the locking claw 6b becomes sufficiently large.

  On the other hand, in order to release the locks of both supports 5, 5, for example, a tip of a flathead screwdriver or the like is inserted between the bottom surface of the release protrusion 11 and the top surface of one support body 5 and lifted to release the release protrusion 11. Is opened, the locking force of the locking groove 6a with respect to the lock claw 6b is released, and the connection lock state of the supports 5 and 5 can be easily released. For this reason, it becomes possible to easily replace the wire harness H.

  Further, in a state where the respective wire harnesses H are held, both the supports 5 and 5 are deformed to reduce their diameters, and the fastener body 1 becomes compact. For this reason, it is possible to prevent interference between the outer surfaces of the supports 5 and 5 and other vehicle body parts around them, and it is possible to freely attach the wire harness fastener even in a narrow place, which is versatile. improves.

  And in the dismantling of the vehicle body, when separating the wire harness H and the wire harness fastener for recycling, as shown in FIG. 5, when the fastener body 1 is strongly pulled upward (arrow direction), The latching claws 19a, 19a of the clip 2 are hooked on the lower hole edge of the fixing hole 3a and elastically deformed inward from each other through the dovetail grooves 19b, 19b between the bellows portions. For this reason, the respective locking claws 19a, 19a can come out of the fixing hole 3a relatively easily. This facilitates separation work for recycling.

  Due to the elastic deformation action of the support legs 17 and 17 and the connecting pieces 18 and 18 of the stem portion 15, as shown in FIG. 6, it is possible to sufficiently cope with the vehicle body panel 3 having different plate thicknesses L and L1. is there.

  Moreover, it is possible to hold regardless of the number of the wire harnesses H. For example, as shown in FIG. 7, when there is one wire harness H, as shown in FIG. As shown in FIG. 10, in the case of four wires, the number of wires such as six as shown in FIG. 10 is determined by the holding portion 7 via the support arms 8 and 8 and the protrusions 9 and 9. Since the harness H is supported in the surrounding state, it can be always firmly and securely held.

  That is, the holding part 7 always holds each wire harness H in a surrounding state while the basic shape of the rhombus changes the inner angle depending on the number of the wire harnesses H, so that the holding force becomes high. Even if a strong upward force is applied, the projections 9 and 9 do not slip out.

  FIGS. 11 to 14 show a first embodiment corresponding to the invention described in claim 2, and the basic configuration of the base 4 of the fastener body 1, both supports 5, 5, the lock mechanism 6, the clip 2, etc. Since this is the same as the previous embodiment, a specific description thereof will be omitted.

  That is, a pair of locking grooves 20, 20 are formed on the inner upper surface of the base 4 on the both supports 5, 5 side, and on the inner surfaces facing the both supports 5, 5, a wire harness is used on the inside. A pair of semicircular arc-shaped holding parts 21 and 21 for inserting and holding two cables K and K are provided.

  The locking grooves 20 and 20 are continuously formed and formed in a substantially rectangular long groove shape, and folded-back protrusions 20a and 20a are integrally formed on each inner end edge.

  Each of the holding portions 21 and 21 has a semicircular inner diameter slightly smaller than the outer diameter of the cables K and K so as to hold the cables K and K in a pinched state. In addition, projecting portions 22, 22 projecting substantially in abutment with each other are integrally formed on the opposing inner surfaces of the supports 5, 5 on the base 4 side. The cables K, K are connected to the lower surfaces of the front ends of the protrusions 22, 22 through the protrusions 22, 22 with the elastic deformation of the supports 5, 5 in the direction of diameter reduction. Locking protrusions 22a and 22a, which are a pair of locking portions that are locked to the locking grooves 20 and 20 when moved in the direction of the base 4, are integrally provided.

  Further, the protrusions 22 and 22 are such that when the locking protrusions 22a and 22a are locked in the locking grooves 20 and 20, the tip surfaces 22b and 22b of the protrusions 22 and 22 are elastic. It is comprised so that it may collide with a contact state.

  The support protrusions 12 are provided in the vicinity of the opening 10 on the inner surface of the support 5 on the one side, as in the previous embodiment, while the support protrusion 12 is provided on the inner surface of the support 5 on the other side. A contact surface 13 on which the support protrusion 12 can be elastically contacted is formed.

  Hereinafter, the operation of the present embodiment will be described. First, as shown in FIGS. 12 and 13, the base 4 is attached to the vehicle body panel 3 by the clip 2 via the fixing hole 3 a as in the previous embodiment. After fixing, when both supports 5 and 5 are naturally deformed in advance in the diameter increasing direction and the opening 10 is opened, the two cables K and K are bundled by hand and the opening is left as it is. 10 is pushed into each holding part 21, 21 and held.

  Thereafter, when the finger-hanging portions 5d and 5d of both the supports 5 and 5 are picked with fingers and forcedly deformed inward (in the direction of diameter reduction), as shown in FIG. At the same time, the locking projections 22a and 22a of the projections 22 and 22 are engaged to obtain an engaged state, and the tip edges 22b and 22b of the projections 22 and 22 are abutted against each other. The

  When this abutment is performed, a reaction force substantially outward (in the direction of the arrow in FIG. 14) acts on each projection 22 and 22, and each reaction force acts on each locking projection 22a and 22a. Communicated. For this reason, the locking protrusions 22a and 22a are strongly locked to the protrusions 20a and 20a by increasing the locking force in the reaction force directions with respect to the locking grooves 20 and 20, respectively. To do. For this reason, the internal cables K, K can be firmly held in combination with the strong locking force of the lock mechanism 6 due to the elastic contact between the support protrusion 12 and the contact surface 13.

  Moreover, the cables K and K can be firmly held by simply elastically deforming the two supports 5 and 5 in the direction of diameter reduction with each other, so that the fastening operation becomes extremely easy. Since the other configuration is the same as that of the previous embodiment, the same effect can be obtained.

  16 to 19 show a second embodiment of the invention of claim 2, the basic configuration is substantially the same as that of the first embodiment except for the difference between the supports 5 and 5. In the point which provided the one holding | maintenance part 31 collectively.

  That is, the fastener body 1 is formed to be small in the radial direction as a whole, the width length W of the base portion 4 is set to be shorter than the previous one, and the opposing widths of the supports 5 and 5 are also set to be small. A pair of semicircular arc-shaped holding portions 31a, 31a constituting the one holding portion 31 is formed on each inner surface.

  The pair of engaging grooves 20 and 20 and the pair of protrusions 22 and 22 are the same as those in the first embodiment except that the length direction is shortened.

  Therefore, according to this embodiment, as shown in FIGS. 17 to 19, after the base portion 4 is fixed to the vehicle body panel 3 by the clip 2 through the fixing holes 3a as described above, both supports When 5 and 5 are naturally deformed in advance in the diameter-enlarging direction and the opening 10 is opened, one cable K is directly pushed from the opening 10 between the holding portions 31a and 31a and held. Let

  Thereafter, when the finger-holding portions 5d and 5d of both the supports 5 and 5 are picked with fingers and forcedly deformed inward (in the direction of reduced diameter), as shown in FIG. At the same time, the locking projections 22a and 22a of the projections 21 and 21 are engaged to obtain an engaged state, and at the same time, the leading edges 22b and 22b of the projections 22 and 22 are abutted against each other. The

  When this abutment is performed, a reaction force substantially outward (in the direction of the arrow in FIG. 19) acts on each of the protrusions 21 and 21, and each reaction force acts on each of the locking protrusions 22a and 22a. Communicated. For this reason, the locking protrusions 22a and 22a are strongly locked to the protrusions 20a and 20a by increasing the locking force in the reaction force directions with respect to the locking grooves 20 and 20, respectively. To do. For this reason, the internal cable K can be firmly held in combination with the strong locking force of the lock mechanism 6 due to the elastic contact between the support protrusion 12 and the contact surface 13.

  In addition, since the cable K can be firmly held only by the operation of elastically deforming both the supports 5 and 5 in the direction of diameter reduction, the fastening operation becomes extremely easy.

  The present invention is not limited to the configuration of each of the embodiments described above. For example, the fastener body 1 can be applied not only to the clip 2 having the above configuration but also to various clips. A double-sided adhesive tape may be bonded to the lower surface and fixed with a double-sided tape applied to the target member. In addition, the target member is not limited to a vehicle body, and can be applied to any device or device such as a home appliance or office equipment.

  In addition, the wire harness may be of any type, and can be applied to various types regardless of the outer diameter.

  Further, as means for elastically deforming both supports 5 and 5 in the direction of diameter reduction, the wire harness H can be used in addition to pinching both finger-hanging portions 5d and 5d and elastically deforming inward as in the above-described embodiments. It is also possible to deform the supports 5 and 5 in the direction of diameter reduction by using a force for pushing the cable K from the opening 10 into the holding parts 7, 21, 31 from above.

  In addition, each of the supports 5 and 5 is not elastically deformed, but one side is fixed, and only the other side is elastically deformed inward to be locked to the support 5 on one side. It is also possible.
