Description

本発明は、例えば自動車などに装備されるパネルの取付け孔に嵌着して、パネルにホースやワイヤハーネス等を固定するのに用いられる樹脂クリップに関し、特にパネルの取付け孔に挿入する部分の出代を少なくすることができる樹脂クリップに関するものである。   The present invention relates to a resin clip that is used to fix a hose, a wire harness, or the like to a panel by being fitted into a mounting hole of a panel mounted on, for example, an automobile. The present invention relates to a resin clip that can reduce the cost.

自動車の車体や内装などのパネルには、ホースやワイヤハーネス等の各種部品を固定するための取付け孔が設けられている。そして、この取付け孔にパネルの片側から樹脂クリップを嵌着させ、この樹脂クリップを介して、各種部品のパネルへの固定が行われている。   Mounting holes for fixing various parts such as a hose and a wire harness are provided in a panel of an automobile body or interior. A resin clip is fitted into the mounting hole from one side of the panel, and various parts are fixed to the panel via the resin clip.

樹脂クリップは、例えば特許文献1に開示されている部品取付脚などに見られるように、パネルの片面に当接する基板部と、この基板部から延出されてパネルの取付け孔に挿入される脚部とを有し、脚部が、基板部から脚部挿入方向に延出される支柱と、この支柱の先端部から、一段曲げ形状で、基板部に向けて外方に広がるように傾斜して取付け孔より広幅に延出される一対の係止片とを有している。   For example, as seen in the component mounting leg disclosed in Patent Document 1, the resin clip has a board part that contacts one side of the panel and a leg that extends from the board part and is inserted into the mounting hole of the panel. And a leg portion extending in the leg insertion direction from the substrate portion, and the tip portion of the pillar is inclined in a one-step bent shape so as to spread outward toward the substrate portion. And a pair of locking pieces extending wider than the mounting hole.

樹脂クリップの脚部をパネルの片面側から取付け孔に差し込むと、係止片の一段曲げ部より先の傾斜部が取付け孔によって内方に押され、この傾斜部が一段曲げ部を曲げ支点として内方に押し撓められる。そして基板部がパネルの片面に当接したとき、傾斜部が外方に弾性復元し、係止片がパネルの裏面に係合することで、脚部が抜け止めされて、樹脂クリップが取付け孔に嵌着するようになっている。   When the leg part of the resin clip is inserted into the mounting hole from one side of the panel, the inclined part ahead of the one-step bending part of the locking piece is pushed inward by the mounting hole, and this inclined part uses the one-step bending part as a bending fulcrum. It is pushed and bent inward. When the board part comes into contact with one side of the panel, the inclined part is elastically restored outward, and the locking piece engages with the back side of the panel, so that the leg part is prevented from coming off and the resin clip is attached to the mounting hole. It is supposed to be fitted in.

特許第2818138号公報Japanese Patent No. 2818138

かかる樹脂クリップでは、パネルの取付け孔に挿入する脚部の出代が少ないものほど、嵌着に際し、パネルの裏面側に必要な隙間が少なくて済むため望ましい。   In such a resin clip, it is preferable that the leg portion inserted into the mounting hole of the panel has a small allowance because a necessary gap is small on the back surface side of the panel at the time of fitting.

しかし、既存製品から係止片を従来の一段曲げ形状としたまま脚部の出代を少なくすると、それに伴って係止片の荷重点から曲げ支点(一段曲げ部)までの距離が短くなり、脚部の挿入抵抗が増加するため、脚部が挿入しにくくなったり、場合によっては挿入不能になるという問題があった。   However, if the length of the leg portion is reduced while keeping the locking piece in the conventional one-step bending shape from the existing product, the distance from the load point of the locking piece to the bending fulcrum (one-step bending portion) is shortened accordingly, Since the insertion resistance of the leg portion is increased, there is a problem that the leg portion becomes difficult to insert or in some cases cannot be inserted.

本発明は、上記のような問題に鑑みてなされたもので、パネルの取付け孔に挿入する脚部の挿入抵抗が増加するのを抑えながら、該脚部の出代を少なくすることができる樹脂クリップを提供することを目的としている。   The present invention has been made in view of the above-described problems, and is a resin that can reduce the protrusion of the leg while suppressing an increase in the insertion resistance of the leg inserted into the mounting hole of the panel. The purpose is to provide clips.

上記課題を解決するための手段としての請求項1に係る発明の構成は、取付け孔を有するパネルの上記取付け孔に嵌着される樹脂クリップであって、上記パネルの片面に係合する基板部と、上記基板部から延出されて上記取付け孔に挿入される脚部とを有し、上記脚部が、上記基板部から脚部挿入方向に延出される支柱と、上記支柱の先端部から、多段曲げ形状で、上記基板部に向けて外方に広がるように傾斜して上記取付け孔より広幅に延出される一対の係止片とを有していることを特徴とするものである。   According to a first aspect of the present invention, there is provided a resin clip that is fitted into the mounting hole of a panel having a mounting hole, and is a substrate portion that engages with one side of the panel. And a leg portion that extends from the substrate portion and is inserted into the mounting hole, the leg portion extending from the substrate portion in the leg insertion direction, and a tip portion of the pillar In addition, it has a multi-stage bent shape, and has a pair of locking pieces that are inclined so as to spread outward toward the substrate portion and extend wider than the mounting hole.

The distance from the bending fulcrum can be increased, and the leg allowance can be reduced while suppressing the insertion resistance of the leg from increasing.

請求項2に係る発明の構成は、請求項1に係る発明の構成である樹脂クリップにおいて、上記係止片が、根元側にいくにつれて薄肉になっていくことを特徴とするものである。   According to a second aspect of the present invention, there is provided a resin clip according to the first aspect of the present invention, wherein the locking piece is thinned toward the root side.

請求項2に係る発明の構成を採用することにより、係止片の最初の曲げ部より根元側の基部を剛性の低い弱断面部とし、脚部挿入時、係止片が取付け孔によって内方に押されたとき、係止片は弱断面部より先の部分がその弱断面部を曲げ支点として内方に撓むので、既存製品から係止片を従来の一段曲げ形状としたまま脚部の出代を少なくした樹脂クリップに比べて、係止片の荷重点と曲げ支点との間の距離を長くすることができ、脚部の挿入抵抗が増加するのを抑えながら、脚部の出代を少なくすることができる。   By adopting the configuration of the invention according to claim 2, the base portion on the base side from the first bent portion of the locking piece is a weak cross-sectional portion having low rigidity, and when the leg portion is inserted, the locking piece is inward by the mounting hole. When it is pushed, the portion of the locking piece ahead of the weak cross section bends inward with the weak cross section as a bending fulcrum, so that the leg piece remains in the conventional one-step bent shape from the existing product. Compared to a resin clip with a reduced allowance, the distance between the load point of the locking piece and the bending fulcrum can be increased, and the increase in leg insertion resistance can be suppressed while suppressing the increase in leg insertion resistance. The bill can be reduced.

また、係止片の最初の曲げ部より先の傾斜部の途中に応力集中を起こす形状変化部、つまり曲げ部を設けても、要するに係止片を多段曲げ形状としても、内面リブによって安定して係止片全体で脚部引抜き方向の荷重を受け持つことができ、係止片の引抜きに対する強度低下を回避することができる。
By adopting the configuration of the invention according to claim 3, when the leg piece is inserted, when the locking piece is pushed inward by the mounting hole, the stress is concentrated on the base part on the base side from the first bent part of the locking piece. By doing so, the part of the locking piece is bent inward with the base part as the bending fulcrum, so that the locking part of the locking piece from the existing product has been kept in the conventional one-step bending shape, and the leg allowance has been reduced. Compared to the resin clip, the distance between the load point of the locking piece and the bending fulcrum can be increased, and the rise of the leg can be reduced while suppressing the insertion resistance of the leg from increasing. it can.
In addition, even if a shape change part that causes stress concentration in the middle of the inclined part ahead of the first bent part of the locking piece, that is, a bending part, in short, even if the locking piece has a multistage bending shape, it is stabilized by the inner rib. Thus, the entire locking piece can handle the load in the leg pulling direction, and a reduction in strength against the pulling of the locking piece can be avoided.

以下、本発明を実施するための形態を図面に基づいて説明する。本実施形態に係る樹脂クリップは、車両用ワイヤハーネスのベルトクランプに実施したものである。   Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The resin clip according to the present embodiment is implemented on a belt clamp of a vehicle wire harness.

図1乃至図3に示すように、ベルトクランプ1は、ベルト10、バックル20、及び本実施形態に係る樹脂クリップ30を、合成樹脂材によって一体に成形してなるものである。このベルトクランプ1は、図4に示すように、ベルト10及びバックル20によってワイヤハーネス2を結束し、図8に示すように、自動車の車体や内装などのパネル3の配線箇所に設けられた取付け孔4に樹脂クリップ30を嵌着することで、この樹脂クリップ30を介して、パネル3の配線箇所にワイヤハーネス2を留め付けることができる。   As shown in FIGS. 1 to 3, the belt clamp 1 is formed by integrally molding a belt 10, a buckle 20, and a resin clip 30 according to the present embodiment with a synthetic resin material. As shown in FIG. 4, the belt clamp 1 binds the wire harness 2 with a belt 10 and a buckle 20, and as shown in FIG. 8, the belt clamp 1 is provided at a wiring location of a panel 3 such as a car body or interior of an automobile. By fitting the resin clip 30 in the hole 4, the wire harness 2 can be fastened to the wiring portion of the panel 3 through the resin clip 30.

図1乃至図3に示すように、ベルト10は、一定の幅で真直ぐに延びる帯状に形成されて可撓性を有し、その基端部11はバックル20に結合され、先端部12は自由端になっている。ベルト10の片面には、係合歯列13がベルト10の長さ方向に沿って一定のピッチで形成されている。また、ベルトクランプ1で結束したワイヤハーネス2がその長さ方向にずれ動くのを防止するためのリブ14が係合歯列13の両側に形成されている。   As shown in FIGS. 1 to 3, the belt 10 is formed in a belt shape having a certain width and extending straight, has flexibility, and its base end portion 11 is coupled to a buckle 20, and the tip end portion 12 is free. At the end. On one side of the belt 10, engagement teeth 13 are formed at a constant pitch along the length direction of the belt 10. In addition, ribs 14 are formed on both sides of the engaging tooth row 13 for preventing the wire harness 2 bound by the belt clamp 1 from shifting in the length direction.

図1乃至図3に示すように、バックル20は、その内部がベルト10を通すための挿通路21となった箱形状に形成され、その挿通路21の一端はバックル20の前側面に開口されてベルト挿入口22になり、他端はバックル20の後側面に開口されてベルト引出し口23になっている。このバックル20の上面後端部にベルト10の基端部11が結合され、ベルト10の係合歯列13及びリブ14が形成された片面が前方に向けられている。一方、樹脂クリップ30は、バックル20の下側に形成されている。   As shown in FIGS. 1 to 3, the buckle 20 is formed in a box shape having an insertion passage 21 through which the belt 10 passes, and one end of the insertion passage 21 is opened on the front side surface of the buckle 20. Thus, the belt insertion port 22 is formed, and the other end is opened on the rear side surface of the buckle 20 to form a belt drawing port 23. The base end portion 11 of the belt 10 is coupled to the rear end portion of the upper surface of the buckle 20, and one side of the belt 10 on which the engagement tooth row 13 and the rib 14 are formed is directed forward. On the other hand, the resin clip 30 is formed below the buckle 20.

また、バックル20は、その天板部24の前端部から折返し部25を介して天板部24の内側(挿通路21の上部)に延出される可撓性を有する片持ち梁状の係合片26を有している。この係合片26の先端部には、ベルト10の係合歯列13に係合する2つの係合爪27が下方に向けて突出形成されている。そして、バックル20の挿通路21は、係合片26の下面とバックル20の内底面との間において、ベルト挿入口22からベルト引出し口23に向けてベルト10を通すことができる。係合爪27は、係合片26の上方への撓み、下方への弾性復元を利用して、ベルト10を引き締めるときの係合歯列13の通過は許容し、その逆方向の係合歯列13の通過は阻止する。   Further, the buckle 20 has a flexible cantilever-like engagement extending from the front end portion of the top plate portion 24 to the inside of the top plate portion 24 (upper portion of the insertion path 21) via the folded portion 25. It has a piece 26. Two engaging claws 27 that engage with the engaging tooth row 13 of the belt 10 are formed to protrude downward at the tip of the engaging piece 26. The insertion path 21 of the buckle 20 can pass the belt 10 from the belt insertion port 22 toward the belt drawing port 23 between the lower surface of the engagement piece 26 and the inner bottom surface of the buckle 20. The engaging claw 27 allows the passage of the engaging tooth row 13 when the belt 10 is tightened by using the upward bending of the engaging piece 26 and the elastic recovery downward, and the engaging teeth in the opposite direction. The passage of row 13 is blocked.

ベルトクランプ1によるワイヤハーネス2の結束作業は、ベルト10の係合歯列13及びリブ14が形成された前面と、バックル20の上面とを、ワイヤハーネス2の結束箇所の外周面に対向させ、ベルト10をワイヤハーネス2の外周に巻き付けると共に、該ベルト10をその先端部12からバックル20の挿通路21に通して引き締める。この引き締めに伴ってベルト10の係合歯列13がバックル20における係合片26の係合爪27を乗り越えて通過しており、所定の引き締め状態において相互が係合し、ベルト10が抜け止めされて、ベルト10とバックル20とがロックされる。これによって、図4に示すように、ワイヤハーネス2がベルト10及びバックル20によって結束される。   The binding work of the wire harness 2 by the belt clamp 1 is performed such that the front surface of the belt 10 on which the engagement tooth row 13 and the rib 14 are formed and the upper surface of the buckle 20 are opposed to the outer peripheral surface of the binding portion of the wire harness 2. The belt 10 is wound around the outer periphery of the wire harness 2, and the belt 10 is tightened through the insertion path 21 of the buckle 20 from the front end portion 12 thereof. As a result of this tightening, the engagement teeth row 13 of the belt 10 passes over the engagement claws 27 of the engagement pieces 26 in the buckle 20 and is engaged with each other in a predetermined tightening state, so that the belt 10 is prevented from coming off. Thus, the belt 10 and the buckle 20 are locked. As a result, the wire harness 2 is bound by the belt 10 and the buckle 20 as shown in FIG.

図5(A),図6,図8に示すように、パネル3の取付け孔4に嵌着される樹脂クリップ30は、パネル3の片面に係合する基板部40と、基板部40から延出されて取付け孔4に挿入される脚部50とを有し、脚部50が、基板部40から脚部挿入方向に向けて延出される支柱60と、支柱60の先端部から基板部40に向けて外方に広がるように傾斜して取付け孔4より広幅に延出される一対の係止片70とを有して構成されている。   As shown in FIGS. 5A, 6, and 8, the resin clip 30 that is fitted into the mounting hole 4 of the panel 3 includes a substrate portion 40 that engages with one side of the panel 3, and extends from the substrate portion 40. A leg portion 50 that is taken out and inserted into the mounting hole 4, the leg portion 50 extends from the substrate portion 40 in the leg insertion direction, and the substrate portion 40 from the tip end portion of the pillar 60. And a pair of locking pieces 70 that are inclined so as to spread outwardly and extend wider than the mounting hole 4.

図5(A)に示すように、この樹脂クリップ30は、その脚部50の出代h1を図5(A)の仮想線で示す既存製品30Aの脚部の出代h2より少なくしたものであって、その際に、係止片70を従来の一段曲げ形状から後述する二段以上の多段曲げ形状としたものであり、係止片70は、支柱60の先端部から、二段以上の多段曲げ形状で、基板部40に向けて外方に広がるように傾斜して取付け孔4より広幅に延出されている。図7に、図5の左側の係止片70を拡大してハッチングを省略した状態で示し、図5(A),図6,図8、及び図7を参照しながら係止片70の構造を説明する。なお、図5の左右一対の係止片70は支柱60の軸芯線61を対称軸として軸対称構造を有している。   As shown in FIG. 5 (A), the resin clip 30 has a leg portion 50 with an allowance h1 less than an allowance h2 of the leg portion of the existing product 30A indicated by the phantom line in FIG. 5 (A). In this case, the locking piece 70 is changed from a conventional one-stage bent shape to a multi-stage bent shape of two or more stages, which will be described later. It is a multi-stage bent shape, and is inclined so as to spread outward toward the substrate portion 40 and extends wider than the mounting hole 4.

One bent portion is added to the first inclined portion (first inclined portion) 73 one by one. For example, in the case of a three-stage bent shape, one intermediate bent portion is added to the first inclined portion 73, and the intermediate bent portion becomes a second-stage bent portion, which is continuously provided at the tip of the second-stage bent portion. The inclined part to be used becomes the second inclined part. The second-stage bent portion 74 and the second inclined portion 75 become a third-stage bent portion and a third inclined portion, respectively. In the case of a four-step bent shape, two intermediate bent portions are added to the first inclined portion 73, of which the bent portion on the base side of the locking piece 70 becomes a second-stage bent portion, and the second-stage bent portion.

The inclined portion becomes the third inclined portion. The second-stage bent portion 74 and the second inclined portion 75 become a fourth-stage bent portion and a fourth inclined portion, respectively.

また、係止片70はその二段曲げ形状(多段曲げ形状)において、一段目曲げ部(最初の曲げ部)72より根元側の基部71における支柱60との角部内面に付けられる丸み71aより先の先端部71bの肉厚T1を、一段目曲げ部(最初の曲げ部)72より先の第一傾斜部73及び第二傾斜部75それぞれの肉厚T2及びT3(最初の傾斜部から最終の傾斜部までのそれぞれの傾斜部の肉厚)より薄くしてある。より具体的には、第二傾斜部75の肉厚T3より第一傾斜部73の肉厚T2が薄く(最終の傾斜部から最初の傾斜部にいくにつれてそれぞれの傾斜部の肉厚が薄くなり)、その第一傾斜部(最初の傾斜部)73の肉厚T2より基部71における先端部71bの肉厚T1が薄くなっている。つまり係止片70は、その根元側にいくにつれて薄肉になっている。   Further, in the two-stage bent shape (multi-stage bent shape), the locking piece 70 has a round 71a attached to the inner surface of the corner portion of the base portion 71 of the base portion 71 on the base side with respect to the first-stage bent portion (first bent portion) 72. The thicknesses T1 and T3 of the first inclined part 73 and the second inclined part 75 ahead of the first-stage bent part (first bent part) 72 are set to the thickness T1 of the tip part 71b. (Thickness of each inclined part up to the inclined part). More specifically, the thickness T2 of the first inclined portion 73 is thinner than the thickness T3 of the second inclined portion 75 (the thickness of each inclined portion becomes thinner as going from the final inclined portion to the first inclined portion). ), The thickness T1 of the tip 71b of the base 71 is thinner than the thickness T2 of the first inclined portion (first inclined portion) 73. That is, the locking piece 70 becomes thinner as it goes to the base side.

さらに、係止片70はその二段曲げ形状(多段曲げ形状)において、一段目曲げ部(最初の曲げ部)72より根元側の基部71における先端部71bの内面から第2傾斜片部(最終の傾斜部)75の内面にわたる内面リブ76を設けている。   Further, in the two-stage bent shape (multi-stage bent shape), the locking piece 70 has a second inclined piece (final) from the inner surface of the tip 71b at the base 71 on the base side from the first-stage bent (first bent) 72. The inner surface rib 76 is provided over the inner surface of the inclined portion.

また、係止片70の二段曲げ形状(多段曲げ形状)において、一段目曲げ部(最初の曲げ部)72より根元側の基部71と第二傾斜部(最終の傾斜部)75とをそれぞれ真直ぐに延長して直接連設させたときにできる一段曲げ形状での一段曲げ部の外面角部を、図7の斜線で示すように、斜めに落とし、該一段曲げ形状での一段曲げ部の肉厚を薄くするように、一段目曲げ部(最初の曲げ部)72より根元側の基部71と第二傾斜部(最終の傾斜部)75とを一段目曲げ部(最初の曲げ部)72、第一傾斜部(最初の傾斜部)73、及び二段目曲げ部(最終の曲げ部)74を介して連設している。   Further, in the two-stage bending shape (multi-stage bending shape) of the locking piece 70, the base portion 71 and the second inclined portion (final inclined portion) 75 on the base side from the first-stage bent portion (first bent portion) 72 are respectively provided. As shown by the diagonal lines in FIG. 7, the outer surface corners of the one-step bent portion formed in the one-step bent shape formed when extending straight and continuously connected are slanted, and the one-step bent portion of the one-step bent shape is dropped. The base portion 71 and the second inclined portion (final inclined portion) 75 on the base side from the first-stage bent portion (first bent portion) 72 are connected to the first-stage bent portion (first bent portion) 72 so as to reduce the thickness. The first inclined portion (first inclined portion) 73 and the second-stage bent portion (final bent portion) 74 are connected.

上記構成を有する樹脂クリップ30では、係止片70は支柱60の先端部から、二段以上の多段曲げ形状で、基板部40に向けて外方に広がるように傾斜して取付け孔4より広幅に延出されており、脚部挿入時、取付け孔4によって内方に押される係止片70の第二傾斜部(最終の傾斜部)75のパネル3に対する傾斜角度θ2を、既存製品30Aから係止片を従来の一段曲げ形状としたまま脚部の出代を少なくした図5(A)の仮想線で示す樹脂クリップ30Bの一段曲げ形状の係止片における一段曲げ部より先の傾斜部のパネル3に対する傾斜角度θ2に比べて小さくすることなく、樹脂クリップ30Bに比べて、係止片70の一段目曲げ部(最初の曲げ部)72より根元側の基部71の長さを短くすることができ、つまり樹脂クリップ30Bに比べて、係止片70の一段目曲げ部(最初の曲げ部)72を係止片70の根元に近い位置に設定することができるので、樹脂クリップ30Bに比べて、係止片70の荷重点Pから曲げ支点(この場合一段目曲げ部(最初の曲げ部)72)までの距離を長くすることができ、脚部50の挿入抵抗が増加するのを抑えながら、或いは、脚部50の挿入抵抗を増加させることなく、脚部50の出代を少なくh1(h2>h1)にすることができる。
なお、係止片70の一段目曲げ部72より先の傾斜部(第一傾斜部73及び第二傾斜部75)(最初の傾斜部から最終の傾斜部までのそれぞれの傾斜部)のパネル3に対する傾斜角度(傾斜角度θ1及び傾斜角度θ2)は、樹脂クリップ30Bの係止部の一段曲げ部から先の傾斜部のパネル3に対する傾斜角度θ2と同様に、既存製品30Aの係止片の一段曲げ部から先の傾斜部のパネル3に対する傾斜角度θ3より小さい(θ3>θ2>θ1)。
In the resin clip 30 having the above-described configuration, the locking piece 70 has a multi-stage bending shape of two or more steps from the front end portion of the support column 60 and is inclined so as to spread outward toward the substrate portion 40 and wider than the mounting hole 4. The inclination angle θ2 of the second inclined portion (final inclined portion) 75 of the locking piece 70 that is pushed inward by the mounting hole 4 at the time of insertion of the leg portion with respect to the panel 3 is determined from the existing product 30A. An inclined portion ahead of the one-step bent portion in the one-step bent engagement piece of the resin clip 30B shown by the phantom line in FIG. The length of the base portion 71 on the base side from the first-stage bent portion (first bent portion) 72 of the locking piece 70 is shortened as compared with the resin clip 30B without reducing the inclination angle θ2 with respect to the panel 3. That is, resin clip 3 Compared to 0B, the first-stage bent portion (first bent portion) 72 of the locking piece 70 can be set at a position close to the root of the locking piece 70, so that the locking piece 70 is compared to the resin clip 30B. The distance from the load point P to the bending fulcrum (in this case, the first-stage bending portion (first bending portion) 72) can be increased, and the increase in insertion resistance of the leg portion 50 is suppressed, or the leg portion Without increasing the insertion resistance of 50, the allowance of the leg 50 can be reduced and h1 (h2> h1).
In addition, the panel 3 of the inclination part (the 1st inclination part 73 and the 2nd inclination part 75) (each inclination part from the 1st inclination part to the last inclination part) ahead of the 1st stage bending part 72 of the latching piece 70 is shown. The inclination angle (inclination angle θ1 and inclination angle θ2) with respect to is similar to the inclination angle θ2 with respect to the panel 3 of the first inclined portion from the one-step bent portion of the engaging portion of the resin clip 30B. It is smaller than the inclination angle θ3 with respect to the panel 3 of the inclined portion from the bent portion (θ3>θ2> θ1).

また、係止片70の二段以上の多段曲げ形状において、係止片70は根元側にいくにつれて薄肉になっており、係止片70の一段目曲げ部(最初の曲げ部)72より根元側の基部71を剛性の低い弱断面部77とし、脚部挿入時、係止片70の第二傾斜部(最終の傾斜部)75が取付け孔4によって内方に押されたとき、係止片70は弱断面部70より先の部分72,73,74,75が該弱断面部77を曲げ支点として内方に撓むので、樹脂クリップ30Bに比べて、係止片70の荷重点Pと曲げ支点(弱断面部77)との間の距離を長くすることができ、脚部50の挿入抵抗が増加するのを抑えながら、或いは、脚部50の挿入抵抗を増加させることなく、脚部50の出代を少なくh1(h2>h1)にすることができる。   Further, in the multi-stage bent shape of the locking piece 70 having two or more steps, the locking piece 70 becomes thinner as it goes to the root side, and the root is formed from the first-stage bent portion (first bent portion) 72 of the locking piece 70. When the base portion 71 on the side is a weak cross-sectional portion 77 with low rigidity and the second inclined portion (final inclined portion) 75 of the locking piece 70 is pushed inward by the mounting hole 4 when the leg portion is inserted, In the piece 70, the portions 72, 73, 74, 75 ahead of the weak cross section 70 bend inward with the weak cross section 77 as a bending fulcrum, so that the load point P of the locking piece 70 is larger than that of the resin clip 30B. The distance between the fulcrum and the bending fulcrum (weak cross section 77) can be increased, and the leg can be prevented from increasing the insertion resistance of the leg 50 or without increasing the insertion resistance of the leg 50. It is possible to make h1 (h2> h1) with less allowance for the portion 50.

さらに、係止片70の二段以上の多段曲げ形状において、係止片70は一段目曲げ部(最初の曲げ部)72より根元側の基部71における先端部71bの内面から第2傾斜片部(最終の傾斜部)75の内面にわたる内面リブ76を設けており、係止片70の基部71における先端部71bを剛性の低い弱断面部77とし、脚部挿入時、係止片70の第二傾斜部(最終の傾斜部)75が取付け孔4によって内方に押されたとき、該弱断面部77に応力集中させることで、係止片70は弱断面部70より先の部分72,73,74,75が該弱断面部77を曲げ支点として内方に撓むので、樹脂クリップ30Bに比べて、係止片70の荷重点Pと曲げ支点(弱断面部77)との間の距離を長くすることができ、脚部50の挿入抵抗が増加するのを抑えながら、或いは、脚部50の挿入抵抗を増加させることなく、脚部50の出代を少なくh1(h2>h1)にすることができる。
また、係止片70の一段目曲げ部72より先の傾斜部(第一傾斜部73及び第二傾斜部75)(最初の傾斜部から最終の傾斜部までの傾斜部)の途中に応力集中を起こす形状変化部、つまり一つ以上の曲げ部(中間の曲げ部や最終の曲げ部)を設けても、要するに係止片70を二段以上の多段曲げ形状としても、内面リブ76によって安定して係止片70全体で脚部引抜き方向の荷重を受け持つことができ、係止片70の引抜きに対する強度低下を回避することができる。
Further, in the multi-stage bending shape of the locking piece 70 having two or more steps, the locking piece 70 is a second inclined piece portion from the inner surface of the tip 71b in the base portion 71 on the base side from the first-stage bending portion (first bending portion) 72. (Final inclined portion) An inner surface rib 76 extending over the inner surface of 75 is provided, and the distal end portion 71b of the base portion 71 of the locking piece 70 is a low-rigidity weak cross-sectional portion 77. When the two inclined portions (final inclined portions) 75 are pushed inward by the attachment holes 4, stress is concentrated on the weak cross-sectional portion 77, so that the locking piece 70 is a portion 72, which is ahead of the weak cross-sectional portion 70. 73, 74, and 75 bend inward with the weak cross section 77 as a bending fulcrum, and therefore, between the load point P of the locking piece 70 and the bending fulcrum (weak cross section 77) as compared with the resin clip 30B. The distance can be increased and the increase in insertion resistance of the leg 50 is suppressed. Alternatively, or without increasing the insertion resistance of the leg portion 50, the allowance of the leg portion 50 can be reduced to h1 (h2> h1).
Further, stress is concentrated in the middle of the inclined portion (the first inclined portion 73 and the second inclined portion 75) (the inclined portion from the first inclined portion to the final inclined portion) ahead of the first-stage bent portion 72 of the locking piece 70. Even if one or more bent portions (intermediate bent portion or final bent portion) are provided, or the locking piece 70 has a multi-stage bent shape of two or more steps, the inner rib 76 can stabilize the shape. Thus, the entire locking piece 70 can handle the load in the leg drawing direction, and a decrease in strength of the locking piece 70 with respect to the drawing can be avoided.

また、上記構成を有する樹脂クリップ30では、係止片70は支柱60の先端部から、二段曲げ形状で、基板部40に向けて外方に広がるように傾斜して取付け孔4より広幅に延出されており、係止片70の一段目曲げ部72より根元側の基部71における支柱60との角部内面に付けられる丸み71aより先の先端部の肉厚T1を第一傾斜部72及び第二傾斜部75のそれぞれの肉厚T2及びT3より薄くすると共に、基部71における先端部71aの内面から第2傾斜片部75の内面にわたる内面リブ76を設けており、係止片70の基部71における先端部71aを剛性の低い弱断面部77とし、脚部挿入時、係止片70の第二傾斜部75が取付け孔4によって内方に押されたとき、該弱断面部77に応力集中させることで、係止片70は弱断面部77より先の部分72,73,74,75がその弱断面部77を曲げ支点として内方に撓むので、樹脂クリップ30Bに比べて、係止片70の荷重点Pと曲げ支点(弱断面部77)との間の距離を長くすることができ、脚部50の挿入抵抗が増加するのを抑えながら、或いは、脚部50の挿入抵抗を増加させることなく、脚部50の出代を少なくh1(h2>h1)にすることができる。
また、係止片70の一段目曲げ部72より先の傾斜部(第一傾斜部73及び第二傾斜部75)の途中に応力集中を起こす形状変化部、つまり二段目曲げ部74を設けても、要するに係止片70を二段曲げ形状としても、内面リブ76によって安定して係止片70全体で脚部引抜き方向の荷重を受け持つことができ、係止片70の引抜きに対する強度低下を回避することができる。
さらに、係止片70の二段曲げ形状は、二段以上の多段曲げ形状の中で最もシンプルな形状(構造)であり、樹脂クリップ30を容易に製造し、安価に提供することができる。
なお、係止片70の一段目曲げ部72より先の傾斜部(第一傾斜部73及び第二傾斜部75)のパネル3に対する傾斜角度(傾斜角度θ1及び傾斜角度θ2)は、樹脂クリップ30Bの一段曲げ部から先の傾斜部のパネル3に対する傾斜角度(図ではθ2)と同様に、既存製品30Aの一段曲げ部から先の傾斜部のパネル3に対する傾斜角度θ3より小さい(θ3>θ2>θ1)。
Further, in the resin clip 30 having the above-described configuration, the locking piece 70 has a two-stage bent shape from the tip end portion of the support column 60 and is inclined so as to spread outward toward the substrate portion 40 so as to be wider than the mounting hole 4. The first inclined portion 72 has a wall thickness T1 at the tip end thereof beyond the rounded portion 71a attached to the inner surface of the corner portion with the support 60 in the base portion 71 on the base side from the first-stage bent portion 72 of the locking piece 70. And an inner surface rib 76 extending from the inner surface of the distal end portion 71a to the inner surface of the second inclined piece portion 75 in the base portion 71, so as to be thinner than the respective thicknesses T2 and T3 of the second inclined portion 75. The distal end portion 71a of the base portion 71 is a weak cross-sectional portion 77 having low rigidity. When the second inclined portion 75 of the locking piece 70 is pushed inward by the mounting hole 4 when the leg portion is inserted, Locking piece 7 by concentrating stress Since the portions 72, 73, 74, 75 ahead of the weak cross section 77 bend inward with the weak cross section 77 as a bending fulcrum, the bending point and the load point P of the locking piece 70 are bent as compared with the resin clip 30B. The distance between the fulcrum (weak cross section 77) can be increased and the leg 50 can be prevented from increasing the insertion resistance of the leg 50 or without increasing the insertion resistance of the leg 50. Can be reduced to h1 (h2> h1).
In addition, a shape changing portion that causes stress concentration, that is, a second-stage bending portion 74 is provided in the middle of the inclined portion (first inclined portion 73 and second inclined portion 75) ahead of the first-stage bent portion 72 of the locking piece 70. In short, even if the locking piece 70 is formed in a two-stage bent shape, the entire inner surface of the locking piece 70 can stably handle the load in the leg pull-out direction by the inner rib 76, and the strength of the locking piece 70 against pulling out can be reduced. Can be avoided.
Further, the two-stage bent shape of the locking piece 70 is the simplest shape (structure) of the two or more multi-stage bent shapes, and the resin clip 30 can be easily manufactured and provided at low cost.
The inclination angle (inclination angle θ1 and inclination angle θ2) of the inclined portion (first inclined portion 73 and second inclined portion 75) ahead of the first-stage bent portion 72 of the locking piece 70 with respect to the panel 3 is the resin clip 30B. Similarly to the inclination angle (θ2 in the figure) of the first inclined portion to the panel 3 of the previous inclined portion, the inclination angle θ3 of the existing product 30A from the first bent portion to the panel 3 of the previous inclined portion is smaller (θ3>θ2>). θ1).

May be extended with an inclination angle (an inclination angle smaller than an inclination angle θ1 of the first inclined portion (first inclined portion) 73 with respect to the panel 3). Further, the tip 71b of the base 71, the first inclined portion (first inclined portion) 73, and the second inclined portion (final inclined portion) 75 (however, excluding the distal end portion beyond the engagement step portion described later) The first inclined portion 73 has a thickness T2 that is thinner than the thickness T3 of the second inclined portion 75 (each from the final inclined portion to the first inclined portion). The thickness T1 of the distal end portion 71b of the base 71 is thinner than the thickness T2 of the first inclined portion (first inclined portion) 73. As described above, the thickness may be decreased gradually from the second inclined portion (final inclined portion) 75 to the distal end portion 71b of the base 71, or may be continuously reduced.

また、内面リブ76は、係止片70の幅方向中央部に形成され、その表面76aは平らな四角形に形成され、断面形状は基部71における先端部71bの内面から第2傾斜片部(最終の傾斜部)75の内面にわたる中凹状で二段(多段)に曲げられた内面と、内面リブ76の表面76aとの隙間を埋めるように高さの低い略三角形状に形成されている。そして、係止片70の内面は、内面リブ76を設けた幅方向中央部において基部71における先端部71bの内面上に角部78を有して一段曲げ形状に形成され、内面リブ76のない幅方向両端部において二段曲げ形状(多段曲げ形状)に形成されている。係止片70は、具体的には、弱断面部77より先の部分72,73,74,75が該弱断面部77の内面角部78を曲げ支点として内方に撓む。   Further, the inner rib 76 is formed at the center in the width direction of the locking piece 70, the surface 76 a is formed in a flat quadrangle, and the cross-sectional shape is the second inclined piece (final part) from the inner surface of the tip 71 b in the base 71. The inclined portion is formed in a substantially triangular shape with a low height so as to fill a gap between the inner surface bent in two steps (multi-step) and the surface 76a of the inner rib 76. The inner surface of the locking piece 70 is formed in a one-step bent shape with a corner portion 78 on the inner surface of the distal end portion 71 b of the base portion 71 at the center in the width direction where the inner surface rib 76 is provided, and without the inner surface rib 76. It is formed in a two-step bending shape (multi-step bending shape) at both ends in the width direction. Specifically, in the locking piece 70, the portions 72, 73, 74, 75 ahead of the weak cross-section portion 77 bend inward with the inner corner portion 78 of the weak cross-section portion 77 as a bending fulcrum.

And a hole wall engaging surface 79b facing the wall surface. In addition, the hole wall locking surface 79b is also formed as a middle convex curved surface curved in the width direction so as to follow the arc portion extending in the minor axis direction of the attachment hole 4.

ベルトクランプ1によるワイヤハーネス2のパネル3への留め付け作業は、樹脂クリップ30の脚部50をパネル3の上面側から取付け孔4に差し込む。これにより、脚部50が取付け孔4に挿入されるのに伴って、係止片70の第二傾斜部(最終の傾斜部)75が取付け孔4によって内方に押され、係止片70の弱断面部77より先の部分72,73,74,75が該弱断面部77の内面角部78を曲げ支点として内方に撓められる。そして、基板部40のフランジ42の先端部がパネル3の上面における取付け孔4の開口周辺部に当接したとき、係止片70の係合段部79におけるパネル抜止め面79aが取付け孔4を通過し、その係合段部79が取付け孔4に挿入されることで、係止片70の弱断面部77より先の部分72,73,74,75が該弱断面部77の内面角部78を曲げ支点として外方に弾性復元し、係合段部79における孔壁係止面79bが係止片70の弾性力によって取付け孔4の壁面に弾性的に圧接される。   To fasten the wire harness 2 to the panel 3 with the belt clamp 1, the leg portion 50 of the resin clip 30 is inserted into the mounting hole 4 from the upper surface side of the panel 3. Accordingly, as the leg portion 50 is inserted into the mounting hole 4, the second inclined portion (final inclined portion) 75 of the locking piece 70 is pushed inward by the mounting hole 4, so that the locking piece 70. The portions 72, 73, 74 and 75 ahead of the weak cross section 77 are bent inward with the inner surface corner 78 of the weak cross section 77 as a bending fulcrum. When the front end portion of the flange 42 of the substrate portion 40 comes into contact with the periphery of the opening of the mounting hole 4 on the upper surface of the panel 3, the panel retaining surface 79 a in the engaging step portion 79 of the locking piece 70 is attached to the mounting hole 4. And the engaging step 79 is inserted into the mounting hole 4, so that the portions 72, 73, 74, 75 ahead of the weak cross section 77 of the locking piece 70 are the inner surface angles of the weak cross section 77. The hole 78 is elastically restored outward with the portion 78 as a bending fulcrum, and the hole wall locking surface 79b of the engagement step 79 is elastically pressed against the wall surface of the mounting hole 4 by the elastic force of the locking piece 70.

また、脚部50をさらに取付け孔4に挿入する。すると、基板部40のフランジ42が広がりながらその先端部がパネル3の上面における取付け孔4の開口周辺部に弾性的に圧接される。そして、樹脂クリップ30の脚部50をさらに取付け孔4に挿入し、基板部40のフランジ42がそれ以上広がることができないところまでパネル3の上面に押し付けて、手を離すと、フランジ42の弾性力によって脚部50が取付け孔4から抜ける方向に戻り始める。この脚部50の抜け動作に伴って、係合段部79におけるパネル抜止め面79aがパネル3の裏面における取付け孔4の開口縁部に押し付けられて係合し、その係合段部79が取付け孔4に係合することで、脚部50が抜け止めされて、パネル3が基板部40と係合片70との間で挟持され、樹脂クリップ30がパネル3の嵌着される。   Further, the leg portion 50 is further inserted into the mounting hole 4. Then, while the flange 42 of the base plate part 40 is expanded, the tip part thereof is elastically pressed against the peripheral part of the opening of the mounting hole 4 on the upper surface of the panel 3. Then, when the leg portion 50 of the resin clip 30 is further inserted into the mounting hole 4 and pressed against the upper surface of the panel 3 until the flange 42 of the substrate portion 40 can no longer expand, and the hand is released, the elasticity of the flange 42 is obtained. Due to the force, the leg portion 50 starts to return in the direction of coming out of the mounting hole 4. As the leg 50 is pulled out, the panel retaining surface 79a of the engaging step 79 is pressed against the opening edge of the mounting hole 4 on the back surface of the panel 3 and the engaging step 79 is engaged. By engaging with the attachment hole 4, the leg portion 50 is prevented from coming off, the panel 3 is sandwiched between the substrate portion 40 and the engagement piece 70, and the resin clip 30 is fitted to the panel 3.

これによって、ベルト10及びバックル20によって結束されたワイヤハーネス2が、樹脂クリップ30を介して、パネル3の配線箇所に留め付けられる。このとき、基板部40のフランジ42は、パネル3の面直方向の樹脂クリップ30のガタ付きを防止すると共に、ベルトクランプ1の取付け姿勢を安定させる機能を果たすと共に、取付け孔4の周囲のシール機能を果たす。係合片70の係合段部79は、樹脂クリップ30の軸芯線61を取付け孔4の中心に一致させる芯合わせ(長径方向及び短径方向の両方向の位置決め)機能を果たし、ベルトクランプ1の取付け姿勢をさらに安定させる。支柱60の基部における横断面形状をT字形にする、基板41の下面と支柱60の左右側面との角部に形成されたリブ62は、樹脂クリップ30がその軸芯線61を中心に回転するのを規制する回り止めとなり、ベルト10とバックル20によって結束されたワイヤハーネス2をその長さ方向を取付け孔4の長径方向に一致させ、保持する機能を果たす。また、基板部40のフランジ42は、パネル3の厚さが変化しても、そのパネル3の厚さに対応して係合段部79におけるパネル抜止め面79aをパネル3の裏面における取付け孔4の開口縁部に押し付けて係合させるので、同じ樹脂クリップ30で厚さの異なる数種のパネル3に対応可能とする機能を果たす。なお、係合片70の係合段部79は、階段状に多段複数を形成してもよく、パネル3の厚さが変化しても、そのパネル3の厚さに対応したいずれかの係合段部79のパネル抜止め面79aがパネル3の裏面における取付け孔4の開口縁部に押し付けて係合するため、同じ樹脂クリップ30で厚さの異なる数種のパネル3に対応可能とする機能を果たす。   As a result, the wire harness 2 bound by the belt 10 and the buckle 20 is fastened to the wiring portion of the panel 3 via the resin clip 30. At this time, the flange 42 of the base plate portion 40 prevents the play of the resin clip 30 in the direction perpendicular to the panel 3 and functions to stabilize the mounting posture of the belt clamp 1 and seals around the mounting hole 4. Fulfills the function. The engagement step portion 79 of the engagement piece 70 performs a centering function (positioning in both the major axis direction and the minor axis direction) for aligning the axial core 61 of the resin clip 30 with the center of the mounting hole 4. Further stabilize the mounting posture. The ribs 62 formed at the corners of the bottom surface of the substrate 41 and the left and right side surfaces of the support column 60 that make the cross-sectional shape at the base of the support column 60 T-shaped are such that the resin clip 30 rotates about its axis 61. The wire harness 2 bound by the belt 10 and the buckle 20 has a function of holding the wire harness 2 with its length direction aligned with the long diameter direction of the mounting hole 4. Further, the flange 42 of the board portion 40 has a panel retaining surface 79a in the engaging step portion 79 corresponding to the thickness of the panel 3 even if the thickness of the panel 3 changes. Since it presses and engages with the opening edge part of 4, the function which makes it possible to respond | correspond to several types of panels 3 from which thickness differs with the same resin clip 30 is fulfill | performed. Note that the engagement step portion 79 of the engagement piece 70 may be formed in a plurality of steps, and even if the thickness of the panel 3 changes, any one of the engagement step portions 79 corresponding to the thickness of the panel 3 is obtained. Since the panel retaining surface 79a of the stepped portion 79 is pressed and engaged with the opening edge of the mounting hole 4 on the back surface of the panel 3, the same resin clip 30 can be used for several types of panels 3 having different thicknesses. Fulfills the function.

そして、上記のとおり、樹脂クリップ30は、脚部50の挿入抵抗が増加するのを抑えながら、或いは、脚部50の挿入抵抗を増加させることなく、脚部50の出代を少なくh1(h2<h1)にしたので、嵌着に際し、パネル3の裏面側に必要な隙間が少なくて済み、省スペース化などによって裏面側に他の構造が接近して配置されているパネル3に対してワイヤハーネス2を留め付けることができる。   And as above-mentioned, the resin clip 30 reduces h1 (h2) with little protrusion of the leg part 50, suppressing the insertion resistance of the leg part 50 increasing, or without increasing the insertion resistance of the leg part 50. <H1), it is possible to reduce the necessary gap on the back surface side of the panel 3 when fitting, and wire is attached to the panel 3 in which other structures are arranged close to the back surface side due to space saving or the like. The harness 2 can be fastened.

以上、本発明に係る樹脂クリップの一実施形態を説明したが、本発明はそれに限定されるものではなく、特許請求の範囲に記載された発明の範囲内で適宜変更することができるものである。   As mentioned above, although one Embodiment of the resin clip concerning this invention was described, this invention is not limited to it, It can change suitably within the range of the invention described in the claim. .

例えば、本実施形態に係る樹脂クリップ30は、車両用ワイヤハーネスのベルトクランプに実施したが、この種のベルトクランプには、一体型とセパレート型があり、その一体型の一例がベルトクランプ1である。つまりベルト10とバックル20からなるクランプ本体を樹脂クリップ30の基板部40上に一体成形する。一方、セパレート型は、クランプ本体を樹脂クリップ30とは別に一体成形し、樹脂クリップ30の基板部40上には、係合片26を有しておらず、内部が単にベルト10を通すためだけの挿通路21となった箱形状を一体成形する。このセパレート型では、クランプ本体のベルト10を樹脂クリップ30側の箱形状に通した状態で、ワイヤハーネス2を結束することで、一体型と同様に、クランプ本体によって結束されたワイヤハーネス2が、樹脂クリップ30を介して、パネル3に留め付けられる。このように、樹脂クリップ30は、一体型とセパレート型、いずれのベルトクランプにも実施することができる。また、クランプ以外に、様々なパネル取付け対象部品の保持具に対して実施することができる。このとき、基板部40のフランジ42や係止片70の係合段部79などは任意に省略することができる。つまり樹脂クリップ30は、厚さが同じパネル3にだけ対応する場合、基板部40をパネル3の取付け孔4より大きな基板41によって形成しておくことで、パネル3を基板41の下面と係止片70の第二傾斜部75の先端面との間に挟持して、パネル3に嵌着することができる。   For example, the resin clip 30 according to the present embodiment is applied to a belt clamp of a vehicle wire harness, but this type of belt clamp includes an integrated type and a separate type, and an example of the integrated type is the belt clamp 1. is there. That is, the clamp body composed of the belt 10 and the buckle 20 is integrally formed on the substrate portion 40 of the resin clip 30. On the other hand, in the separate type, the clamp body is integrally formed separately from the resin clip 30, and the engagement piece 26 is not provided on the substrate portion 40 of the resin clip 30. The box shape that becomes the insertion passage 21 is integrally formed. In this separate type, by binding the wire harness 2 in a state where the belt 10 of the clamp main body is passed through the box shape on the resin clip 30 side, the wire harness 2 bound by the clamp main body, like the integrated type, It is fastened to the panel 3 via the resin clip 30. As described above, the resin clip 30 can be applied to any one of a belt clamp and an integral type. Moreover, it can implement with respect to the holder of various panel attachment object components other than a clamp. At this time, the flange 42 of the board part 40, the engagement step part 79 of the locking piece 70, and the like can be arbitrarily omitted. That is, when the resin clip 30 corresponds only to the panel 3 having the same thickness, the substrate portion 40 is formed by the substrate 41 larger than the mounting hole 4 of the panel 3 so that the panel 3 is locked to the lower surface of the substrate 41. It can be sandwiched between the front end surface of the second inclined portion 75 of the piece 70 and can be fitted to the panel 3.
