Description

本発明は、自動車等の車両に備えられるワイヤーハーネスを車体に締結固定するために用いられるワイヤーハーネス用締結具に係り、詳しくは、車両解体時にワイヤーハーネスを車体から簡易に取り外し可能にするために、容易に分断可能にしたワイヤーハーネス用締結具に関する。   The present invention relates to a wire harness fastener used for fastening and fixing a wire harness provided in a vehicle such as an automobile to a vehicle body, and more specifically, in order to easily remove the wire harness from the vehicle body when the vehicle is disassembled. The present invention relates to a fastener for a wire harness that can be easily divided.

この種のワイヤーハーネス用締結具としては、例えば、図３３、図３４に示すような合成樹脂製のものが公知である（例えば、特許文献１参照。）。このワイヤーハーネス用締結具１は、ワイヤーハーネスＷＨを結束するための可撓性を有するバンド２と、バンド２とは別体に形成され車体Ｂ側の取付孔３に差し込み固定される固定部４とからなっている。バンド２の基端部にはバンド２の先端側を挿通させて抜け止め状に係止させる挿通係止孔５を有するヘッド部６を一体に形成し、このヘッド部６に係合突起７を設ける一方、固定部４に、係合突起７が着脱可能に嵌合する嵌合孔８を設けている。
そして、このように構成されたワイヤーハーネス用締結具１は、車両解体時に、固定部４からヘッド部６を引き離す方向に引っ張ることで、嵌合孔８から係合突起７が外され、ワイヤーハーネスＷＨを車体Ｂから容易に取り外すことができる、というものである。 As this type of fastener for a wire harness, for example, a synthetic resin as shown in FIGS. 33 and 34 is known (see, for example, Patent Document 1). The wire harness fastener 1 includes a flexible band 2 for binding the wire harness WH, and a fixing portion 4 that is formed separately from the band 2 and is inserted into and fixed to the mounting hole 3 on the vehicle body B side. It is made up of. The base portion of the band 2 is integrally formed with a head portion 6 having an insertion locking hole 5 that is inserted into the distal end side of the band 2 and locked in a retaining manner, and an engagement protrusion 7 is formed on the head portion 6. On the other hand, the fixing portion 4 is provided with a fitting hole 8 into which the engaging protrusion 7 is detachably fitted.
And the fastener 1 for wire harnesses comprised in this way pulls the engagement protrusion 7 from the fitting hole 8 by pulling in the direction which pulls the head part 6 away from the fixing | fixed part 4 at the time of vehicle disassembly, and a wire harness The WH can be easily detached from the vehicle body B.

特開平１１−２１５６６７号公報JP-A-11-215667

しかしながら、上記公知のワイヤーハーネス用締結具では、車両解体時に、嵌合孔８から係合突起７を引き出す方向が、真直ぐではなく斜めとなる場合、引き離し力が有効に作用せず、容易に分離できない虞があり、ヘッド部６の引き離し方向が真直ぐな方向に特定されるという取扱い上不利な面があった。また、ワイヤーハーネスを車体から取り外してもバンドはワイヤーハーネスに巻き付けられたままの状態にあるため、車体からのワイヤーハーネスの取り外し後、さらに、ワイヤーハーネスからバンドを取り外す必要があるという問題もあった。   However, in the known wire harness fastener, when the direction in which the engaging protrusion 7 is pulled out from the fitting hole 8 is not straight but oblique when the vehicle is disassembled, the pulling force does not act effectively and is easily separated. There is a possibility that it cannot be performed, and there is a disadvantage in handling that the direction in which the head portion 6 is separated is specified as a straight direction. There was also a problem that after removing the wire harness from the vehicle body, it was necessary to remove the band from the wire harness after the wire harness was removed from the vehicle body. .

本発明は、このような問題を解消するためになされたものであり、その目的とするところは、何れの方向に引き離し力が作用しても容易に分断させることができてワイヤーハーネスを車体から取り外すことができるうえ、同時にワイヤーハーネスからバンドを取り外すこともでき、これらの取り外し作業、解体作業性の向上を図れるワイヤーハーネス用締結具を提供することにある。   The present invention has been made to solve such a problem, and the object of the present invention is to easily divide the wire harness from the vehicle body regardless of the direction in which the pulling force acts. It is possible to remove the band from the wire harness at the same time, and to provide a wire harness fastener capable of improving the removal work and the dismantling workability.

本発明は、請求項１に記載のように、発明の内容を理解し易くする為に図１〜図３２に付した符号を参照して説明すると、ワイヤーハーネス（ＷＨ）を結束するための可撓性を有するバンド（１１）と、バンド（１１）の基端部に一体に連設され、バンド（１１）の先端側を挿通させて抜け止め状に係止させる挿通係止孔（１２）を貫通状に形成したヘッド部（１３）とを備えている合成樹脂製のワイヤーハーネス用締結具において、ヘッド部（１３）に、車体側の取付孔（１４）に差し込み固定される固定部（１５）が一体に設けられ、ヘッド部（１３）の、バンド（１１）の基端部との連設部であって挿通係止孔（１２）を囲む周壁部（１６）に、一対の脆弱部（１７，１７、２３，２３、２４，２４、２６，２６、２８,２８）が孔貫通方向に沿って形成されていることに特徴を有するものである。   If the present invention is described with reference to the reference numerals attached to FIGS. 1 to 32 for easy understanding of the contents of the invention, the wire harness (WH) can be bound. A flexible band (11) and an insertion locking hole (12) that are integrally connected to the base end of the band (11) and that are inserted in the distal end side of the band (11) and locked in a retaining shape. In a fastener for a wire harness made of a synthetic resin having a head portion (13) formed in a penetrating shape, a fixed portion (inserted into a mounting hole (14) on the vehicle body side and fixed to the head portion (13) ( 15) is provided integrally, and a pair of fragile parts are formed in the peripheral wall portion (16) which is a continuous portion of the head portion (13) with the base end portion of the band (11) and surrounds the insertion locking hole (12).

As shown in FIGS. 7 and 8, a plurality of engagement teeth 18 are arranged at a predetermined pitch in the longitudinal direction on the inner surface side of the band 11. As shown in FIGS. 2 to 4, the head portion 13 integrally connected to the base end portion of the band 11 has a peripheral wall portion 16 surrounding the insertion locking hole 12 having a quadrangular cross section through which the distal end side of the band 11 is inserted. Have. The peripheral wall portion 16 includes a lower wall portion 16a, a pair of left and right side wall portions 16b and 16c erected perpendicularly from the lower wall portion 16a, and an upper wall connecting the upper end portions of the side wall portions 16b and 16c. 16d. The upper wall portion 16 d is formed integrally with the base end portion of the band 11. On the inner surface of the upper wall portion 16d, when the band 11 is inserted from the distal end portion 11a thereof into the insertion locking hole 12 in the arrow X direction (see FIG. 6), the engaging teeth 18 cannot be pulled out in the anti-insertion direction. Engaging serrated locking claws 19 (see FIG. 7) are integrally formed.

図２〜図４に示すように、ヘッド部１３において、側壁部１６ｂ，１６ｃの各上端部と連結される上壁部１６ｄの左右両端部には一対の脆弱部１７,１７が挿通係止孔１２の貫通方向（孔貫通方向）に沿って形成されて、ワイヤーハーネスＷＨを車体Ｂから引き離す力で、上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が破断し易くしている。すなわち、脆弱部１７は、上壁部１６ｄの前後方向（孔貫通方向）の幅を側壁部１６ｂ，１６ｃの前後方向長さよりも狭くする形状に形成するとともに、この幅狭の上壁部１６ｄの、側壁部１６ｂ，１６ｃと連設する左右端部のそれぞれの壁厚は、上壁部１６ｄの他の壁厚よりも薄く形成する左右一対の薄肉部２０，２０を有するように構成することによって、上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が破断し易くしている。更に、脆弱部１７は、図２に示すように、幅狭形状の上壁部１６ｄの左右の薄肉部２０，２０のうち、いずれか一方の薄肉部２０の前端部、および他方の薄肉部２０の後端部にそれぞれ平面視においてＶ形状の切欠部２１を上壁部１６ｄの平面視において対角線上に位置するように形成することで、該切欠部２１，２１を発端として上壁部１６ｄの左右の薄肉部２０，２０が容易に分断できるようにしている。   As shown in FIGS. 2 to 4, in the head portion 13, a pair of fragile portions 17, 17 are inserted into the left and right end portions of the upper wall portion 16 d connected to the upper end portions of the side wall portions 16 b, 16 c. 12 is formed along the penetration direction (hole penetration direction) of 12 and the connecting portion between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c is a force that pulls the wire harness WH away from the vehicle body B. It is easy to break. That is, the fragile portion 17 is formed in a shape in which the width in the front-rear direction (hole penetration direction) of the upper wall portion 16d is narrower than the length in the front-rear direction of the side wall portions 16b, 16c. The respective wall thicknesses of the left and right end portions connected to the side wall portions 16b and 16c are configured to have a pair of left and right thin portions 20 and 20 formed thinner than the other wall thicknesses of the upper wall portion 16d. The connecting portions between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c are easily broken. Further, as shown in FIG. 2, the fragile portion 17 includes a front end portion of one of the thin portions 20 and 20 on the left and right of the narrow-shaped upper wall portion 16 d, and the other thin portion 20. By forming the V-shaped cutout portion 21 at the rear end portion so as to be located diagonally in the plan view of the upper wall portion 16d in the plan view, the cutout portions 21 and 21 are used as starting points of the upper wall portion 16d. The left and right thin portions 20, 20 can be easily divided.

ヘッド部１３の下壁部１６ａの下面側には、図６のように、車体Ｂ側の取付孔１４に差し込み固定される固定部１５が一体に設けられ、この固定部１５は下壁部１６ａの下面側に一体に形成された傘型の鍔部１５ａと、この鍔部１５ａの下面側に下向きに一体に突設されたステム部１５ｂと、ステム部１５ｂの先端より上向きに拡開状に突設した左右一対の弾性係止片１５ｃ，１５ｃとを備えている。   On the lower surface side of the lower wall portion 16a of the head portion 13, as shown in FIG. 6, a fixing portion 15 that is inserted into and fixed to the mounting hole 14 on the vehicle body B side is integrally provided. The fixing portion 15 is integrally provided with the lower wall portion 16a. Umbrella-shaped collar portion 15a formed integrally on the lower surface side, a stem portion 15b integrally projecting downward on the lower surface side of the collar portion 15a, and an expanding shape upward from the tip of the stem portion 15b A pair of left and right elastic locking pieces 15c, 15c are provided.

次に、上記構成のワイヤーハーネス用締結具１０を用いてワイヤーハーネスＷＨを車体Ｂに締結固定する要領、および車両解体時にワイヤーハーネスＷＨを車体Ｂから取り外す要領について説明する。   Next, a procedure for fastening and fixing the wire harness WH to the vehicle body B using the wire harness fastener 10 having the above configuration and a procedure for removing the wire harness WH from the vehicle body B when the vehicle is disassembled will be described.

先ず、ワイヤーハーネス用締結具１０でワイヤーハーネスＷＨを車体Ｂに締結固定するには、図１、図５、図６に示すように、バンド１１をワイヤーハーネスＷＨの外周に巻き付け、バンド１１の先端部をヘッド部１３の挿通係止孔１２に挿通させて該バンド１１の係合歯１８を挿通係止孔１２内の係止爪１９に抜け止め状に係止させて締結する。   First, in order to fasten and fix the wire harness WH to the vehicle body B with the wire harness fastener 10, the band 11 is wound around the outer periphery of the wire harness WH as shown in FIGS. The portion is inserted into the insertion locking hole 12 of the head portion 13, and the engagement teeth 18 of the band 11 are locked to the locking claw 19 in the insertion locking hole 12 so as not to come off.

また、図６に示すように、車体Ｂ側の取付孔１４に、固定部１５のステム部１５ｂが差し込まれると、弾性係止片１５ｃ，１５ｃが取付孔１４の周縁に係止されて、鍔部１５ａと弾性係止片１５ｃの先端部との間で車体Ｂの一部が挟持され、これによりワイヤーハーネスＷＨが車体Ｂに装着固定される。   Further, as shown in FIG. 6, when the stem portion 15b of the fixing portion 15 is inserted into the mounting hole 14 on the vehicle body B side, the elastic locking pieces 15c and 15c are locked to the periphery of the mounting hole 14, A part of the vehicle body B is sandwiched between the portion 15a and the tip of the elastic locking piece 15c, whereby the wire harness WH is attached and fixed to the vehicle body B.

次に、車両解体時、ワイヤーハーネスＷＨを車体Ｂから取り外すには、ワイヤーハーネスＷＨにフック部材等を引っ掛けて、ワイヤーハーネスＷＨを車体Ｂから引き離す。すると、ヘッド部１３の側壁部１６ｂ，１６ｃの各上端部と上壁部１６ｄの左右両端部との間に形成されている脆弱部１７，１７が、ワイヤーハーネスＷＨを車体Ｂから引き離す力で、図７、図８に示すように、破断される。この破断によりバンド１１の基端部と一体の上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が分離して、バンド１１とヘッド部１３とが分断するとともに、挿通係止孔１２が破壊する。これによりワイヤーハーネスＷＨを車体Ｂから取り外すことができると同時に、ワイヤーハーネスＷＨからバンド１１を取り外すことができる。   Next, in order to remove the wire harness WH from the vehicle body B when the vehicle is disassembled, a hook member or the like is hooked on the wire harness WH, and the wire harness WH is pulled away from the vehicle body B. Then, the fragile portions 17 and 17 formed between the upper ends of the side wall portions 16b and 16c of the head portion 13 and the left and right end portions of the upper wall portion 16d are the forces that pull the wire harness WH away from the vehicle body B. As shown in FIG. 7 and FIG. As a result of this breakage, the connecting portion between the left and right end portions of the upper wall portion 16d integral with the base end portion of the band 11 and the upper end portions of the side wall portions 16b and 16c is separated, and the band 11 and the head portion 13 are separated. The insertion locking hole 12 is destroyed. Thereby, the wire harness WH can be removed from the vehicle body B, and at the same time, the band 11 can be removed from the wire harness WH.

また、ヘッド部１３の側壁部１６ｂ，１６ｃの各上端部と上壁部１６ｄの左右両端部との間の薄肉部２０による脆弱部１７，１７に加わる破断力は、ワイヤーハーネスＷＨの引き離し方向によって、略変わらず、例えば、斜め前方向からあるいは斜め後ろ方向から引き離されても、常に引き裂く方向の力として作用するので、容易に、この脆弱部１７からバンド１１とヘッド部１３とを分断させることができる。このため、ワイヤーハーネスＷＨをフック部等で引っ掛けて、ワイヤーハーネスＷＨを車体Ｂから引き離す方向に引っ張る簡便な解体作業でも容易に分解できる。   Further, the breaking force applied to the fragile portions 17, 17 by the thin wall portion 20 between the upper end portions of the side wall portions 16b, 16c of the head portion 13 and the left and right end portions of the upper wall portion 16d depends on the direction in which the wire harness WH is pulled away. The band 11 and the head portion 13 can be easily separated from the fragile portion 17 because the force always acts as a tearing force even when pulled away from the diagonally forward direction or diagonally backward direction. Can do. For this reason, it can be easily disassembled even by a simple disassembly operation in which the wire harness WH is hooked by a hook portion or the like and pulled in a direction in which the wire harness WH is pulled away from the vehicle body B.

幅狭形状の上壁部１６ｄの左右の薄肉部２０，２０による脆弱部１７，１７のうち、いずれか一方の薄肉部２０による脆弱部１７の前端部、および他方の薄肉部２０による脆弱部１７の後端部にそれぞれ切欠部２１を形成しているので、ワイヤーハーネスＷＨを車体Ｂから引き離す力が作用すると、切欠部２１に応力が集中して、該切欠部２１を発端として薄肉部２０による脆弱部１７が容易に破断する。また、切欠部２１，２１は上壁部１６ｄの平面視において対角線上に位置するように相互に前後反対方向に向くように形成しているので、前方向又は後ろ方向の一方向からのワイヤーハーネスＷＨを車体Ｂから引き離す力で、一方の薄肉部２０が破断されにくい場合でも、他方の薄肉部２０が破断して、バンド１１とヘッド部１３とを容易に分離させることができる。   Of the fragile portions 17 and 17 due to the left and right thin portions 20 and 20 of the narrow-walled upper wall portion 16d, the front end portion of the fragile portion 17 due to any one thin portion 20 and the fragile portion 17 due to the other thin portion 20. Since the notch portions 21 are formed at the rear end portions, when a force for pulling the wire harness WH away from the vehicle body B is applied, stress concentrates on the notch portion 21, and the thin wall portion 20 starts with the notch portion 21 as a starting point. The fragile portion 17 is easily broken. Moreover, since the notches 21 and 21 are formed so as to be opposite to each other in the front-rear direction so as to be located diagonally in a plan view of the upper wall portion 16d, the wire harness from one direction in the front direction or the rear direction Even when one thin portion 20 is not easily broken by the force of pulling WH away from the vehicle body B, the other thin portion 20 is broken and the band 11 and the head portion 13 can be easily separated.

図９〜図１４は、ワイヤーハーネス用締結具１０の他の実施例（請求項１，２、請求項５に記載の発明の実施例）を示すものであり、図１〜図８に示す上記実施例とは脆弱部の構成を相違し、その他の構成は上記実施例のものと同様であるので、同一部材に同一符号を付して説明を省略し、以下、相違する脆弱部の構成のみについて説明する。   FIGS. 9-14 shows the other Example (Embodiment of invention of Claim 1, 2, 5) of the fastener 10 for wire harnesses, The said shown in FIGS. The configuration of the fragile portion is different from that of the embodiment, and the other configurations are the same as those of the above-described embodiment. Therefore, the same reference numerals are assigned to the same members, and the description thereof is omitted. Will be described.

この実施例では、図９〜図１４に示すように、ヘッド部１３において、左右の側壁部１６ｂ，１６ｃの各前後端にはそれぞれ側面視において「く」の字形状の切欠部２２,２２が、各側壁部１６ｂ，１６ｃの前後方向幅寸法が小さくなるように切欠部２２，２２の先細端部２２ａ，２２ａ同士を対向させた対称位置に形成されていて、これら先細端部２２ａ，２２ａ同士間に、幅狭状の脆弱部２３，２３が設けられている。   In this embodiment, as shown in FIGS. 9 to 14, in the head portion 13, the front and rear ends of the left and right side wall portions 16 b and 16 c are respectively provided with “<”-shaped cutout portions 22 and 22 in a side view. The tapered end portions 22a and 22a of the cutout portions 22 and 22 are formed at symmetrical positions so that the width dimensions in the front-rear direction of the side wall portions 16b and 16c are reduced, and the tapered end portions 22a and 22a are in contact with each other. A narrow fragile portion 23, 23 is provided between them.

このように構成されたワイヤーハーネス用締結具１０では、ワイヤーハーネスＷＨを車体Ｂから引き離す力が作用すると、左右の側壁部１６ｂ，１６ｃに形成された脆弱部２３，２３としての幅狭部に応力が集中して該幅狭部が容易に破断される（図１３、図１４参照）。この破断によりバンド１１とヘッド部１３とが分断するとともに、挿通係止孔１２が破壊する。これによりワイヤーハーネスＷＨを車体Ｂから取り外すことができると同時に、ワイヤーハーネスＷＨからバンド１１を取り外すことができる。   In the wire harness fastener 10 configured as described above, when a force for pulling the wire harness WH away from the vehicle body B is applied, stress is applied to the narrow portions as the fragile portions 23 and 23 formed on the left and right side wall portions 16b and 16c. As a result, the narrow portion is easily broken (see FIGS. 13 and 14). The band 11 and the head portion 13 are divided by this breakage, and the insertion locking hole 12 is broken. Thereby, the wire harness WH can be removed from the vehicle body B, and at the same time, the band 11 can be removed from the wire harness WH.

また、ヘッド部１３の側壁部１６ｂ，１６ｃに前後一対の切欠部２２，２２により形成された脆弱部２３の幅狭部に加わる破断力は、ワイヤーハーネスＷＨの引き離し方向によって、略変わらず、例えば、斜め前方向から或いは斜め後ろ方向から引き離されても、常に引きちぎる方向の力として作用するので、容易に、この脆弱部２３からバンド１１とヘッド部１３とを分断させることができる。   Further, the breaking force applied to the narrow portion of the fragile portion 23 formed by the pair of front and rear cutout portions 22 and 22 on the side wall portions 16b and 16c of the head portion 13 does not substantially change depending on the pulling direction of the wire harness WH. The band 11 and the head portion 13 can be easily separated from the fragile portion 23 because it always acts as a force in a tearing direction even when pulled away from the diagonally forward direction or diagonally backward direction.

図１５〜図２０は、ワイヤーハーネス用締結具１０の更に他の実施例（請求項１〜４、請求項８に記載の発明の実施例）を示すものであり、図１〜図８に示す上記実施例とは脆弱部の構成を相違し、その他の構成は上記実施例のものと同様であるので、同一部材に同一符号を付して説明を省略し、以下、相違する脆弱部の構成のみについて説明する。   15 to 20 show still another embodiment (embodiment of the invention described in claims 1 to 4 and claim 8) of the fastener 10 for wire harness, and are shown in FIGS. The configuration of the fragile portion is different from that of the above-described embodiment, and the other configurations are the same as those of the above-described embodiment. Only that will be described.

この実施例では、図１５〜図２０に示すように、ヘッド部１３において、左右の側壁部１６ｂ，１６ｃに形成される脆弱部２４，２４は、側面視において「く」の字形状の内側切欠部２５ａと外側切欠部２５ｂが各側壁部１６ｂ，１６ｃの厚さ方向寸法が小さくなるように各切欠部２５ａ，２５ｂの先細端部２５ｃ，２５ｄ同士を平面視で重複する位置まで切り欠き形成することにより、上下斜めに位置する薄肉部２４ａ，２４ａを有する形に形成されている。   In this embodiment, as shown in FIGS. 15 to 20, in the head portion 13, the fragile portions 24, 24 formed on the left and right side wall portions 16 b, 16 c The tapered end portions 25c and 25d of the cutout portions 25a and 25b are cut out to a position where they overlap in a plan view so that the portion 25a and the outer cutout portion 25b have a smaller dimension in the thickness direction of the side wall portions 16b and 16c. By this, it is formed in the form which has the thin part 24a, 24a located diagonally up and down.

このように構成されたワイヤーハーネス用締結具１０では、ワイヤーハーネスＷＨを車体Ｂから引き離す力が作用すると、左右の側壁部１６ｂ，１６ｃに形成された薄肉部２４ａ，２４ａに応力が集中して該薄肉部２４ａ，２４ａが容易に破断される（図１９、図２０参照）。この破断によりバンド１１とヘッド部１３とが分断するとともに、挿通係止孔１２が破壊する。これによりワイヤーハーネスＷＨを車体Ｂから取り外すことができると同時に、ワイヤーハーネスＷＨからバンド１１を取り外すことができる。   In the wire harness fastener 10 configured as described above, when a force for pulling the wire harness WH away from the vehicle body B acts, stress concentrates on the thin wall portions 24a and 24a formed on the left and right side wall portions 16b and 16c. The thin portions 24a and 24a are easily broken (see FIGS. 19 and 20). The band 11 and the head portion 13 are divided by this breakage, and the insertion locking hole 12 is broken. Thereby, the wire harness WH can be removed from the vehicle body B, and at the same time, the band 11 can be removed from the wire harness WH.

また、ヘッド部１３の側壁部１６ｂ，１６ｃに形成された薄肉部２４ａ，２４ａに加わる破断力は、ワイヤーハーネスＷＨの引き離し方向によって、略変わらず、例えば、斜め前方向から或いは斜め後ろ方向から引き離されても、常に引き裂く方向の力として作用するので、容易に、バンド１１とヘッド部１３とを分断させることができる。   Further, the breaking force applied to the thin wall portions 24a and 24a formed on the side wall portions 16b and 16c of the head portion 13 is not substantially changed depending on the pulling direction of the wire harness WH. For example, the breaking force is pulled away from the diagonally forward direction or diagonally backward direction. Even if this occurs, it always acts as a force in the tearing direction, so that the band 11 and the head portion 13 can be easily separated.

図２１〜図２６は、ワイヤーハーネス用締結具１０の更に他の実施例（請求項１、３、請求項７に記載の発明の実施例）を示すものであり、図１〜図８に示す上記実施例とは脆弱部の構成を相違し、その他の構成は上記実施例のものと同様であるので、同一部材に同一符号を付して説明を省略し、以下、相違する脆弱部の構成のみについて説明する。   21 to 26 show still another embodiment of the wire harness fastener 10 (embodiments of the invention described in claims 1, 3 and 7), and are shown in FIGS. 1 to 8. The configuration of the fragile portion is different from that of the above-described embodiment, and the other configurations are the same as those of the above-described embodiment. Only that will be described.

この実施例では、図２１〜図２６に示すように、ヘッド部１３において、側壁部１６ｂ，１６ｃの各上端部と連結される上壁部１６ｄの左右両端部に脆弱部２６，２６が挿通係止孔１２の貫通方向（孔貫通方向）に沿って形成されて、ワイヤーハーネスＷＨを車体Ｂから引き離す力で、上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が破断し易くしている。すなわち、脆弱部２６は、上壁部１６ｄの前後方向（孔貫通方向）の幅を側壁部１６ｂ，１６ｃの前後方向長さよりも狭くする形状に形成するとともに、この幅狭形状の上壁部１６ｄの、側壁部１６ｂ，１６ｃと連設する左右端部のそれぞれの壁厚は上壁部１６ｄの他の壁厚よりも薄く形成する左右一対の薄肉部２７，２７を有するように構成することによって、上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が破断し易くしている。   In this embodiment, as shown in FIGS. 21 to 26, in the head portion 13, the fragile portions 26 and 26 are inserted into the left and right end portions of the upper wall portion 16d connected to the upper end portions of the side wall portions 16b and 16c. The connection between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c is formed along the penetration direction (hole penetration direction) of the stop hole 12 and pulls the wire harness WH away from the vehicle body B. The part is easy to break. That is, the fragile portion 26 is formed in a shape in which the width in the front-rear direction (hole penetration direction) of the upper wall portion 16d is narrower than the length in the front-rear direction of the side wall portions 16b, 16c. The wall thicknesses of the left and right end portions connected to the side wall portions 16b and 16c are configured to have a pair of left and right thin portions 27 and 27 formed thinner than other wall thicknesses of the upper wall portion 16d. The connecting portions between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c are easily broken.

このように構成されたワイヤーハーネス用締結具１０では、ワイヤーハーネスＷＨを車体Ｂから引き離す力が作用すると、左右の側壁部１６ｂ，１６ｃに形成された薄肉部２７，２７に応力が集中して該薄肉部２７，２７が容易に破断される（図２５、図２６参照）。この破断によりバンド１１とヘッド部１３とが分断するとともに、挿通係止孔１２が破壊する。これによりワイヤーハーネスＷＨを車体Ｂから取り外すことができると同時に、ワイヤーハーネスＷＨからバンド１１を取り外すことができる。   In the wire harness fastener 10 configured as described above, when a force for pulling the wire harness WH away from the vehicle body B acts, stress concentrates on the thin wall portions 27 and 27 formed on the left and right side wall portions 16b and 16c. The thin portions 27 are easily broken (see FIGS. 25 and 26). The band 11 and the head portion 13 are divided by this breakage, and the insertion locking hole 12 is broken. Thereby, the wire harness WH can be removed from the vehicle body B, and at the same time, the band 11 can be removed from the wire harness WH.

また、ヘッド部１３の側壁部１６ｂ，１６ｃに形成された薄肉部２７，２７に加わる破断力は、ワイヤーハーネスＷＨの引き離し方向によって、略変わらず、例えば、斜め前方向から或いは斜め後ろ方向から引き離されても、常に引き裂く方向の力として作用するので、容易に、バンド１１とヘッド部１３とを分断させることができる。   Further, the breaking force applied to the thin portions 27 and 27 formed on the side wall portions 16b and 16c of the head portion 13 does not substantially change depending on the direction in which the wire harness WH is separated, for example, from the diagonally forward direction or diagonally backward direction. Even if this occurs, it always acts as a force in the tearing direction, so that the band 11 and the head portion 13 can be easily separated.

図２７〜図３２は、ワイヤーハーネス用締結具１０の更に又、他の実施例（請求項１、２、請求項６に記載の発明の実施例）を示すものであり、図１〜図８に示す上記実施例とは脆弱部の構成を相違し、その他の構成は上記実施例のものと同様であるので、同一部材に同一符号を付して説明を省略し、以下、相違する脆弱部の構成のみについて説明する。   27 to 32 show still another embodiment (embodiment of the invention described in claims 1, 2, and 6) of the wire harness fastener 10, and FIGS. The configuration of the fragile portion is different from that of the above-described embodiment, and the other configurations are the same as those of the above-described embodiment. Therefore, the same reference numerals are assigned to the same members, and the description thereof is omitted. Only the configuration will be described.

この実施例では、図２７〜図３２に示すように、ヘッド部１３において、側壁部１６ｂ，１６ｃの各上端部と連結される上壁部１６ｄの左右両端部に脆弱部２８，２８が挿通係止孔１２の貫通方向（孔貫通方向）に沿って形成されて、ワイヤーハーネスＷＨを車体Ｂから引き離す力で、上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が破断し易くしている。すなわち、脆弱部２８は、上壁部１６ｄの前後方向（孔貫通方向）の幅を側壁部１６ｂ，１６ｃの前後方向長さよりも狭くする形状に形成し、また幅狭形状の上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部のうち、いずれか一方の連結部の前端部および後端部に、また他方の連結部の前端部および後端部にそれぞれ平面視においてＶ形状の切欠部２９を形成することで、該切欠部２９，２９を発端として上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が容易に分断できるようにしている。なお、この実施例において、幅狭形状の上壁部１６ｄの側壁部１６ｂ，１６ｃと連設する左右端部のうち、いずれか一方の端部の壁厚は上壁部１６ｄの他の壁厚よりも薄く形成する薄肉部３０（図２８参照）を有するものとすること、あるいは両方の端部の壁厚は上壁部１６ｄの他の壁厚よりも薄く形成する薄肉部３０を有するものとすることが好ましい。   In this embodiment, as shown in FIGS. 27 to 32, in the head portion 13, the weak portions 28, 28 are inserted into the left and right end portions of the upper wall portion 16d connected to the upper ends of the side wall portions 16b, 16c. The connection between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c is formed along the penetration direction (hole penetration direction) of the stop hole 12 and pulls the wire harness WH away from the vehicle body B. The part is easy to break. That is, the weak part 28 is formed in a shape in which the width in the front-rear direction (hole penetration direction) of the upper wall part 16d is narrower than the length in the front-rear direction of the side wall parts 16b, 16c. Of the connecting portions between the left and right end portions and the upper end portions of the side wall portions 16b and 16c, the front end portion and the rear end portion of one of the connecting portions, and the front end portion and the rear end portion of the other connecting portion are respectively flat. By forming the V-shaped cutout portion 29 as viewed, the connecting portion between the left and right end portions of the upper wall portion 16d and the upper end portions of the side wall portions 16b and 16c can be easily divided starting from the cutout portions 29 and 29. I am doing so. In this embodiment, the wall thickness of either one of the left and right end portions connected to the side wall portions 16b, 16c of the narrow-shaped upper wall portion 16d is the other wall thickness of the upper wall portion 16d. A thin-walled portion 30 (see FIG. 28) that is formed thinner than the upper-wall portion 16d, or a thin-walled portion 30 that is formed thinner than the other wall thicknesses of the upper wall portion 16d. It is preferable to do.

このように構成されたワイヤーハーネス用締結具１０では、ワイヤーハーネスＷＨを車体Ｂから引き離す力が作用すると、左右の切欠部２９，２９に応力が集中して上壁部１６ｄの左右両端部と側壁部１６ｂ，１６ｃの各上端部との連結部が容易に破断される（図３１、図３２参照）。この破断によりバンド１１とヘッド部１３とが分断するとともに、挿通係止孔１２が破壊する。これによりワイヤーハーネスＷＨを車体Ｂから取り外すことができると同時に、ワイヤーハーネスＷＨからバンド１１を取り外すことができる。   In the wire harness fastener 10 configured as described above, when a force for pulling the wire harness WH away from the vehicle body B acts, stress concentrates on the left and right cutout portions 29, 29, and both left and right end portions and side walls of the upper wall portion 16d. The connection part with each upper end part of the parts 16b and 16c is easily fractured (see FIGS. 31 and 32). The band 11 and the head portion 13 are divided by this breakage, and the insertion locking hole 12 is broken. Thereby, the wire harness WH can be removed from the vehicle body B, and at the same time, the band 11 can be removed from the wire harness WH.

また、ヘッド部１３の上壁部１６ｄに形成された切欠部２９，２９に加わる破断力は、ワイヤーハーネスＷＨの引き離し方向によって、略変わらず、例えば、斜め前方向から或いは斜め後ろ方向から引き離されても、常に引き裂く方向の力として作用するので、容易に、バンド１１とヘッド部１３とを分断させることができる。   Further, the breaking force applied to the notches 29, 29 formed in the upper wall portion 16d of the head portion 13 does not substantially change depending on the direction in which the wire harness WH is separated, for example, from the diagonally forward direction or from the diagonally backward direction. However, since it always acts as a force in the tearing direction, the band 11 and the head portion 13 can be easily separated.

なお、本発明のワイヤーハーネス用締結具は自動車等の車両以外に、ＯＡ機器等各種産業機械・機器類に備えられるワイヤーハーネスの締結具にも適用できることは言うまでもない。   In addition, it cannot be overemphasized that the fastener for wire harnesses of this invention is applicable also to the fastener of the wire harness with which various industrial machines and apparatuses, such as OA apparatus, are equipped other than vehicles, such as a motor vehicle.
