Description

本発明はワイヤハーネス用のバンドクリップに関し、詳しくは、自動車等に配索するワイヤハーネスに取り付けられて車体の取付穴にクリップを挿入係止するバンドクリップにおいて、ワイヤハーネスに斜め方向の引っ張り力が作用してクリップに回転モーメントが作用してもクリップが取付穴から離脱しないようにするものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band clip for a wire harness, and more specifically, in a band clip that is attached to a wire harness routed in an automobile or the like and inserts and locks the clip into a mounting hole of a vehicle body, This prevents the clip from being detached from the mounting hole even if a rotational moment acts on the clip.

従来、この種のワイヤハーネス用のバンドクリップは種々提案されている。例えば、特開２０１０−１５１１７４号公報で本出願人が提案している図８に示すバンドクリップ１００は、締結バンド１０２を本体１０３から突設したワイヤハーネス取付部１０１と、該ワイヤハーネス取付部１０１と一体成形したクリップ１０５とからなる。該クリップ１０５は本体１０３の外面に突設した皿部１１０から左右一対の支柱部１１１Ａ、１１１Ｂを突設し、該一対の支柱部１１１Ａと１１１Ｂの突出端を連結する架橋部１１２に、短手方向（幅方向）Ｙの両側で且つ長手方向Ｘで左右に位相させて一対の羽根部１１３Ａ、１１３Ｂを基部側の皿部１１０に向けて折り返し状に突設し、各羽根部１１３Ａ、１１３Ｂの外面にそれぞれ係止爪１１４Ａ、１１４Ｂを設けている。また、羽根部１１３Ａと１１３Ｂの隣接する内側端同士を連結する中央連結部１１６を設けている。   Conventionally, various band clips for this type of wire harness have been proposed. For example, the band clip 100 shown in FIG. 8 proposed by the present applicant in Japanese Patent Application Laid-Open No. 2010-151174 includes a wire harness mounting portion 101 in which a fastening band 102 is projected from a main body 103, and the wire harness mounting portion 101. And the clip 105 integrally formed. The clip 105 has a pair of left and right support pillars 111A and 111B protruding from a dish part 110 protruding from the outer surface of the main body 103, and a bridging part 112 connecting the protruding ends of the pair of support pillars 111A and 111B. A pair of blade portions 113A and 113B are projected in a folded manner toward the base portion 110 on both sides of the direction (width direction) Y and in the longitudinal direction X to the left and right, and the blade portions 113A and 113B Locking claws 114A and 114B are provided on the outer surface, respectively. Moreover, the center connection part 116 which connects the adjacent inner ends of blade part 113A and 113B is provided.

前記バンドクリップ１００は締結バンド１０２を図８（Ｃ）に示すようにワイヤハーネス１２０の電線群に巻き付けた後、本体１０３のバンド貫通穴１０３ａに通し、締結バンド１０２に設けた係止溝１０２ａにバンド貫通穴１０３ａに突設した係止片を係止してワイヤハーネス１２０に締結している。ワイヤハーネス１２０を自動車の車体に沿って配索し、車体Ｐに予め設けている長円状の取付穴Ｈにクリップ１０５を挿入し、羽根部１１３Ａ、１１３Ｂを取付穴Ｈに撓ませて押し込み、係止爪１１４Ａ、１１４Ｂを取付穴Ｈの長手方向Ｘの周縁に係止して、取付穴Ｈに固定している。   The band clip 100 wraps the fastening band 102 around the wire group of the wire harness 120 as shown in FIG. 8C, and then passes through the band through hole 103a of the main body 103, and into the locking groove 102a provided in the fastening band 102. The locking piece protruding from the band through hole 103 a is locked and fastened to the wire harness 120. The wire harness 120 is routed along the vehicle body of the automobile, the clip 105 is inserted into an oval mounting hole H provided in advance in the vehicle body P, and the blade portions 113A and 113B are bent and pushed into the mounting hole H. The locking claws 114 </ b> A and 114 </ b> B are locked to the peripheral edge in the longitudinal direction X of the mounting hole H and fixed to the mounting hole H.

前記バンドクリップ１００は羽根部１１３Ａと１１３Ｂとを中央連結部１１６で連結しているため、ワイヤハーネス１２０に短手方向Ｙの引張力が作用し、羽根部１１３Ａ、１１３Ｂが短手方向の一方側に傾く力が作用しても、中央連結部１１６による戻し方向の引張力で羽根部の傾きが抑制され、羽根部の係止爪による取付穴への係止力を保持することができる。   In the band clip 100, since the blade portions 113A and 113B are connected by the central connecting portion 116, a tensile force in the short direction Y acts on the wire harness 120, and the blade portions 113A and 113B are on one side in the short direction. Even if a force that inclines is exerted, the inclination of the blade portion is suppressed by the pulling force in the return direction by the central connecting portion 116, and the locking force to the mounting hole by the locking claw of the blade portion can be maintained.

特開２０１０−１５１１７４号公報JP 2010-151174 A

しかしながら、前記バンドクリップ１００に対して、図９に示すように、クリップ１０５の取付穴Ｈの鉛直方向Ｚに対して傾斜した引張力が作用すると、一対の羽根部１１３Ａ、１１３Ｂの係止爪１１４Ａ、１１４Ｂの取付穴Ｈに対する係止力のみで保持することになる。よって、ワイヤハーネス側からクリップ１０５に対して鉛直方向の強い引張力が作用すると、羽根部１１３Ａ、１１３Ｂが互いに中心に向かって撓み、係止爪１１４Ａ、１１４Ｂが取付穴Ｈの周縁から外れてクリップ１０５が取付穴Ｈから抜ける恐れがある。   However, when a tensile force inclined with respect to the vertical direction Z of the attachment hole H of the clip 105 is applied to the band clip 100 as shown in FIG. 9, the locking claws 114A of the pair of blade portions 113A and 113B are applied. , 114B is held only by the locking force with respect to the mounting hole H. Therefore, when a strong tensile force in the vertical direction acts on the clip 105 from the wire harness side, the blade portions 113A and 113B bend toward each other, and the locking claws 114A and 114B are detached from the peripheral edge of the mounting hole H. There is a possibility that 105 may come out of the mounting hole H.

本発明は前記した問題に鑑みてなされたもので、バンドクリップに対して鉛直方向の引張力が負荷された場合に、クリップの取付穴に対する係止力を高め、取付穴からの離脱を防止することを課題としている。   The present invention has been made in view of the above-described problem, and when a tensile force in the vertical direction is applied to the band clip, the locking force with respect to the attachment hole of the clip is increased and the separation from the attachment hole is prevented. It is an issue.

前記課題を解決するため、本発明は、締結バンドを設けたワイヤハーネス取付部から突設する一対の支柱部の突出端を連結する架橋部に、短手方向の両側で且つ長手方向の左右に位相させて一対の羽根部を前記ワイヤハーネス取付部側の基部側に向けて折り返し状に突設し、各羽根部の外面に係止爪を設け、該係止爪を車体の取付穴の周縁に係止するバンドクリップにおいて、
前記一対の羽根部の係止爪を前記隣接する支柱部側の外向きで且つ前記基部側に向けて傾斜させていることを特徴とするワイヤハーネス用のバンドクリップを提供している。 In order to solve the above-mentioned problems, the present invention provides a bridging portion that connects the protruding ends of a pair of support columns protruding from a wire harness mounting portion provided with a fastening band, on both sides in the short direction and on the left and right in the longitudinal direction. A pair of blade portions are projected in a folded manner toward the base side on the wire harness mounting portion side in phase, and locking claws are provided on the outer surface of each blade portion, and the locking claws are arranged at the periphery of the mounting hole of the vehicle body. In the band clip locked to
There is provided a band clip for a wire harness characterized in that locking claws of the pair of blade portions are inclined outward toward the adjacent support column and toward the base.

前記した羽根部の外面に設ける係止爪は、羽根部の外面にＶ形状の切込を設けて三角形状の係止爪としている。
前記のように、一対の羽根部の各係止爪を、隣接する支柱部側が基部側に向かうように傾斜（言わば、外下向き傾斜）させると、一対の羽根部の係止爪は同一方向に向けて傾斜する方向となる。係止爪を前記のように傾斜させると、鉛直方向の引張負荷がかかると、クリップに回転モーメントが発生し、羽根部は傾斜させた方向に倒れ隣接する外側の支柱部に押し当てられる。このように、クリップが引き抜かれる方向の鉛直方向の負荷が作用すると、羽根部が支柱部に向かって倒れ、支柱部に押し当てられるようにしているため、取付穴から抜き出るのを抑止でき、取付穴へのクリップの保持力を高めることができる。 The locking claw provided on the outer surface of the blade part described above is a triangular locking claw provided with a V-shaped cut on the outer surface of the blade part.
As described above, when the locking claws of the pair of blade portions are inclined (in other words, outwardly inclined) so that the adjacent support column portions are directed toward the base side, the locking claws of the pair of blade portions are in the same direction. It becomes the direction which inclines toward. When the locking claw is tilted as described above, when a tensile load in the vertical direction is applied, a rotational moment is generated in the clip, and the blade portion falls in the tilted direction and is pressed against the adjacent outer support column portion. In this way, when a vertical load in the direction in which the clip is pulled out acts, the blade part falls toward the column part and is pressed against the column part, so that it can be prevented from being pulled out from the mounting hole, The holding force of the clip in the mounting hole can be increased.

前記係止爪の傾斜角度は３゜〜１０゜の範囲としていることが好ましい。
前記傾斜角度を３゜未満と傾斜角度を小さくすると、鉛直方向に引抜力が作用した時に羽根部に生じる回転モーメントは小さくなり支柱部へと倒れ込まなくなる。一方、傾斜角度を１０゜以上とすると、通常の鉛直方向の係止状態で係止爪が取付穴の周縁に接触する面積が小さくなり、通常の係止力が小さくなるか、係止爪の支柱部側の外側部の挿入力が過大となる。 The inclination angle of the locking claw is preferably in the range of 3 ° to 10 °.
When the inclination angle is less than 3 ° and the inclination angle is reduced, the rotational moment generated in the blade portion when a pulling force is applied in the vertical direction is reduced, and it does not fall into the column portion. On the other hand, when the inclination angle is 10 ° or more, the area where the locking claw contacts the periphery of the mounting hole in the normal vertical locking state is reduced, and the normal locking force is reduced or the locking claw The insertion force on the outer side on the column side becomes excessive.

前記各羽根部に上下複数段の前記係止爪を設け、これら複数段の係止爪は平行に傾斜させていることが好ましい。
このように、係止爪を複数段とすることで、取付穴を設けた車体の板厚に対応させることができる。 It is preferable that a plurality of upper and lower stages of the locking claws are provided on each blade portion, and the plurality of stages of locking claws are inclined in parallel.
Thus, by making the latching claws into a plurality of stages, it is possible to correspond to the plate thickness of the vehicle body provided with the mounting holes.

前記ワイヤハーネス取付部は前記締結バンドを突設した本体部の外面に皿部を突設し、該皿部の底面より前記一対の支柱部を突設し、かつ、前記一対の羽根部は互いに近接内側端で且つ前記皿部側端を中央連結部で連結していることが好ましい。
前記した中央連結部を設けると、クリップに短軸方向の引張力が作用した時にクリップを取付穴から抜き出にくくできる。 The wire harness mounting part projects a dish part on the outer surface of the main body part projecting the fastening band, projects the pair of column parts from the bottom surface of the dish part, and the pair of blade parts mutually It is preferable that the near inner end and the dish part side end are connected by a central connecting part.
Providing the above-described central connecting portion makes it difficult to pull out the clip from the mounting hole when a tensile force in the short axis direction acts on the clip.

さらに、前記傾斜させる係止爪は、前記取付穴の周縁の裏面側に引っ掛かる突出量を支柱部側の外側を小さくすると共に内側に向けて漸次大としていることが好ましい。
これは、図１０に示すように、バンドクリップ１００の長手方向Ｘの引張力が負荷された時、クリップ１０５は長手方向Ｘに傾き、傾いた側の羽根部１１３Ｂの係止爪１１４Ｂがダレて内側縁Ｅが破損し、保持力が小さくなる問題がある。
この問題を解決するために、前記のように、破損し易い内側部分の突出量を予め大きくしておくことで、保持力を維持することができる。 Furthermore, it is preferable that the locking claw to be tilted gradually increases the amount of protrusion hooked on the back side of the peripheral edge of the mounting hole toward the inner side while reducing the outer side on the column part side.
As shown in FIG. 10, when the tensile force in the longitudinal direction X of the band clip 100 is applied, the clip 105 is inclined in the longitudinal direction X, and the locking claw 114B of the inclined blade portion 113B is sag. There is a problem that the inner edge E is broken and the holding force is reduced.
In order to solve this problem, as described above, the holding force can be maintained by increasing the protrusion amount of the inner portion that is easily damaged.

前記のように、本発明に係わるバンドクリップは羽根部に設ける係止爪を皿側の基部側へと外下向きに傾斜させているため、バンドクリップに鉛直方向の引抜力が作用した時に、羽根部に回転モーメントが発生し、羽根部を隣接する支柱部に押し当てるように倒すことができる。よって、係止爪が車体の取付穴の周縁から外れて、クリップが取付穴から抜けることを防止でき、クリップの保持力を高めることができる。   As described above, since the band clip according to the present invention has the locking claw provided on the blade portion inclined outward and downward toward the base side on the plate side, when the vertical pulling force acts on the band clip, the blade clip A rotational moment is generated in the portion, and the blade portion can be tilted so as to press against the adjacent strut portion. Therefore, it can prevent that a latching nail | claw remove | deviates from the periphery of the attachment hole of a vehicle body, and a clip remove | deviates from an attachment hole, and can improve the retention strength of a clip.

前記係止爪１６、１７の傾斜角度θは３゜〜１０゜の範囲とし、本実施形態では５゜としている。また、羽根部１４と支柱部１１の隙間寸法および羽根部１５と支柱部１２の隙間寸法は同寸で０．３ｍｍ〜１ｍｍで、本実施形態では０．６ｍｍとしている。   The inclination angle θ of the locking claws 16 and 17 is in the range of 3 ° to 10 °, and in this embodiment is 5 °. Moreover, the clearance dimension between the blade | wing part 14 and the support | pillar part 11 and the clearance gap dimension of the blade | wing part 15 and the support | pillar part 12 are 0.3 mm-1 mm with the same dimension, and are 0.6 mm in this embodiment.

前記構成としたバンドクリップ１は図４に示すように、締結バンド６をワイヤハーネスＷ／Ｈを構成する電線群Ｗに巻き付け、本体５のバンド貫通穴５ａに通し、バンド貫通穴５ａ内で係止溝６ａに係止片を係止してワイヤハーネスＷ／Ｈに固定している。
該ワイヤハーネスＷ／Ｈを車体の配索経路に沿って配索し、車体Ｐに設けた長円形状の取付穴Ｈに前記バンドクリップ１のクリップ３を架橋部１３側から押し込み、羽根部１４、１５の係止爪１６、１７を取付穴Ｈの内周縁に係止して固定している。 As shown in FIG. 4, the band clip 1 configured as described above is wound around the wire group W constituting the wire harness W / H, passed through the band through hole 5a of the main body 5, and engaged in the band through hole 5a. A locking piece is locked in the stop groove 6a and fixed to the wire harness W / H.
The wire harness W / H is routed along the routing route of the vehicle body, the clip 3 of the band clip 1 is pushed into the oval mounting hole H provided in the vehicle body P from the bridging portion 13 side, and the blade portion 14 , 15 locking claws 16, 17 are locked to the inner peripheral edge of the mounting hole H and fixed.

詳細には、本実施形態では、最下段の係止爪１６（１６−１）が取付穴Ｈの対向する一方の長辺ｈａの左側に係止し、最下段の係止爪１７（１７−１）が取付穴Ｈの対向する他方の長辺ｈｂの右側に係止している。また、取付穴Ｈの左右の短辺側の円弧部の内面に沿って支柱部１１、１２が内嵌している。係止爪１６、１７はいずれも外下方向に傾斜させているため、係止爪１６は支柱部１１に隣接する外側部１６ｕが取付穴Ｈの周縁に最も強い力で係止され、同様に係止爪１７は支柱部１２に隣接する外側部１７ｕが取付穴の周縁に最も強い力で係止される。なお、係止爪１６、１７の傾斜角度は５゜程度とゆるやかにしているため、内側部１６ｉ、１７ｉも取付穴Ｈの周縁にしっかりと係止される。   More specifically, in the present embodiment, the lowermost locking claw 16 (16-1) is locked to the left side of one long side ha of the mounting hole H, and the lowermost locking claw 17 (17-). 1) is locked to the right side of the other long side hb of the mounting hole H facing each other. Further, the support columns 11 and 12 are fitted along the inner surfaces of the arc portions on the left and right short sides of the mounting hole H. Since the locking claws 16 and 17 are both inclined outward and downward, the locking claw 16 has its outer portion 16u adjacent to the support column 11 locked to the periphery of the mounting hole H with the strongest force. As for the latching claw 17, the outer side part 17u adjacent to the support | pillar part 12 is latched by the strongest force to the periphery of an attachment hole. In addition, since the inclination angle of the locking claws 16 and 17 is as gentle as about 5 °, the inner portions 16i and 17i are also firmly locked to the periphery of the mounting hole H.

前記のようにクリップ３が取付穴Ｈに係止している状態で、バンドクリップ１の締結バンド６で締結されたワイヤハーネスＷ／Ｈから図５に示すように、取付穴Ｈの鉛直方向Ｚの引張力が負荷され、クリップ３が取付穴Ｈから引き抜き方向に引っ張られる場合がある。その場合、係止爪１６、１７を外下向きに傾斜させているため、係止爪１６、１７に鉛直方向の引き抜き力が作用せず、図５（Ｃ）に示すように、傾斜させた方向に羽根部１４、１５を倒し込み、クリップ全体に回転モーメントが生じ、支柱部１１、１２は取付穴Ｈの周縁に押し当てられる。その結果、支柱部１１、１２と取付穴Ｈの周縁が干渉し、クリップ３が取付穴Ｈから外れるのを防止する。   From the wire harness W / H fastened by the fastening band 6 of the band clip 1 with the clip 3 locked in the mounting hole H as described above, as shown in FIG. May be pulled, and the clip 3 may be pulled from the mounting hole H in the pulling direction. In that case, since the latching claws 16 and 17 are inclined outward and downward, the pulling force in the vertical direction does not act on the latching claws 16 and 17, and the inclined direction as shown in FIG. The blade portions 14 and 15 are tilted down, and a rotational moment is generated in the entire clip, so that the column portions 11 and 12 are pressed against the peripheral edge of the mounting hole H. As a result, the pillars 11 and 12 and the periphery of the mounting hole H interfere with each other, and the clip 3 is prevented from being detached from the mounting hole H.

図６および図７に第２実施形態のバンドクリップを示す。
第２実施形態のバンドクリップでは、羽根部１４、１５に設けた係止爪１６、１７の突出量を長手方向Ｘの内外方向で均等とせず、内側部１６ｉ、１７ｉを大とし、外側部１６ｕ、１７ｕが小さくなるように円弧状（または傾斜状）としている。具体的には、係止爪１６、１７の従来の外形ライン（図中、二点鎖線で示す）に対して、内側部１６ｉ、１７ｉは肉盛りして突出量を大とし、外側部１６ｕ、１７ｕは削って突出量を小としている。 これにより、係止爪１６、１７が取付穴Ｈと係止した時、係止爪１６、１７の外側部の取付穴周縁との引掛量は少なくなるが、内側部１６ｉ、１７ｉの引掛量を大としている。 6 and 7 show a band clip of the second embodiment.
In the band clip of the second embodiment, the protrusions of the locking claws 16 and 17 provided on the blade portions 14 and 15 are not made uniform in the inner and outer directions in the longitudinal direction X, the inner portions 16i and 17i are made larger, and the outer portions 16u. , 17u are arcuate (or inclined) so as to be small. Specifically, the inner portions 16i and 17i are thickened to increase the protruding amount with respect to the conventional outline lines of the locking claws 16 and 17 (indicated by a two-dot chain line in the figure), and the outer portions 16u, 17u is sharpened to reduce the protruding amount. As a result, when the locking claws 16 and 17 are locked with the mounting holes H, the amount of hooking between the outer side of the locking claws 16 and 17 and the peripheral edge of the mounting hole is reduced, but the hooking amounts of the inner portions 16i and 17i are reduced. It ’s big.

係止爪１６、１７は第１実施形態と同様に外下向きに傾斜させており、他の構成も第１実施形態と同様としている。   The locking claws 16 and 17 are inclined outward and downward in the same manner as in the first embodiment, and other configurations are the same as in the first embodiment.

前記のように、係止爪１６、１７の突出量を均等とせずに、支柱部１１、１２に近接する外側部１６ｕ、１７ｕを予め小さくしておくと、バンドクリップ１が長手方向Ｘに引張られてクリップ３が長手方向Ｘに傾いた時、係止爪１６、１７の外側部１６ｕ、１７ｕが取付穴Ｈの周縁で削られるのが防止できる。   As described above, if the outer portions 16u and 17u adjacent to the support columns 11 and 12 are made small in advance without making the protruding amounts of the locking claws 16 and 17 uniform, the band clip 1 is pulled in the longitudinal direction X. Thus, when the clip 3 is inclined in the longitudinal direction X, the outer portions 16u and 17u of the locking claws 16 and 17 can be prevented from being scraped at the periphery of the mounting hole H.

さらに、本発明のバンドクリップは前記第１、第２実施形態に限定されず、羽根部１４、１５とを連結する中央連結部を無くしても良いし、羽根部１４、１５の内外端縁に補強用突起を設けてもよい。   Furthermore, the band clip of the present invention is not limited to the first and second embodiments, and the central connecting portion that connects the blade portions 14 and 15 may be eliminated, and the inner and outer edges of the blade portions 14 and 15 may be eliminated. A reinforcing protrusion may be provided.
