Description

本発明は、自動車の車体等の被取付部材に対して、ワイヤハーネスを取り付けるためのワイヤハーネス用クランプに関するものである。 The present invention relates to a wire harness clamp for attaching a wire harness to a member to be attached such as an automobile body.

従来より、自動車の車体を構成する各種パネルに対して、ワイヤハーネスを取り付けるためのワイヤハーネス用クランプが種々提案されている。
例えば、車体パネルに形成された係止孔に差し込むことによって係止される係止部と、この係止部が裏面中央部に設けられると共に、この係止部の基端部に皿状のシール部材が一体に成形されたワイヤハーネス固定片とから構成されたワイヤハーネスクランプがある（例えば、特許文献１参照。）。
そして、このワイヤハーネス固定片の表面側にワイヤハーネスを巻きテープ等で固定して、係止部を車体パネルに形成された係止孔に差し込むことによって、ワイヤハーネスを車体パネルに取り付けることができると共に、車体パネルと係止部の基端部周囲との隙間をシール部材によって塞いで防水することが可能となる。 Conventionally, various wire harness clamps for attaching a wire harness to various panels constituting a vehicle body have been proposed.
For example, a locking portion that is locked by being inserted into a locking hole formed in the vehicle body panel, and the locking portion is provided at the center of the back surface, and a dish-like seal is provided at the base end of the locking portion. There is a wire harness clamp composed of a wire harness fixing piece in which members are integrally formed (see, for example, Patent Document 1).
And a wire harness can be attached to a vehicle body panel by fixing a wire harness to the surface side of this wire harness fixing piece with a winding tape etc., and inserting a latching | locking part in the latching hole formed in the vehicle body panel. At the same time, the gap between the vehicle body panel and the periphery of the proximal end portion of the locking portion can be sealed with a seal member for waterproofing.

特開平１０−１４０６２号公報（段落（０００８）〜（００１４）、図１〜図３）Japanese Patent Laid-Open No. 10-14062 (paragraphs (0008) to (0014), FIGS. 1 to 3)

しかしながら、前記特許文献１に記載されたワイヤハーネスクランプでは、係止部を係止孔に取り付け後、引き回し作業等によってワイヤハーネスに荷重がかかった場合には、ワイヤハーネス固定部が一様に撓んでしまう。このため、係止部の基端部周縁部分も弾性変形してシール部材と車体パネルとの密着度が低下し、防水性能が低下する虞があるという問題がある。 However, in the wire harness clamp described in Patent Document 1, when a load is applied to the wire harness by a routing operation or the like after the locking portion is attached to the locking hole, the wire harness fixing portion is uniformly bent. I'll be stuck. For this reason, there also exists a problem that the base end part peripheral part of a latching | locking part may also elastically deform, the adhesiveness of a sealing member and a vehicle body panel may fall, and waterproof performance may fall.

そこで、本発明は、上述した問題点を解決するためになされたものであり、係止部を係止孔に取り付け後、引き回し作業等によってワイヤハーネスに荷重がかかっても、シール部材と被取付部材との密着度を維持し、防水性能の低下を防止することが可能となるワイヤハーネス用クランプを提供することを目的とする。 Therefore, the present invention has been made to solve the above-described problems, and after the locking portion is attached to the locking hole, even if a load is applied to the wire harness due to a routing operation or the like, the sealing member and the mounted member are provided. An object of the present invention is to provide a wire harness clamp that can maintain a close contact with a member and prevent a decrease in waterproof performance.

前記目的を達成するため請求項１に係るワイヤハーネス用クランプは、ワイヤハーネスを一方の面に固定可能な細長平板状の基板部と、前記基板部の前記一方の面に対向する他方の面の長手方向略中央部に設けられて被取付部材に形成された係止孔に差し込むことによって弾性的に係止される係止部と、前記係止部の基端部において前記基板部の他方の面と一体に成形されて、前記係止部を前記係止孔に係止した場合に、前記被取付部材と該係止部の基端部周囲との隙間を塞ぐように圧着される皿状のシール部材と、を備え、前記基板部は、前記一方の面の前記皿状のシール部材の投影部分に長手方向に沿って相対向するように立設された少なくとも一対の補強リブを有し、該基板部は、前記一対の補強リブよりも長手方向両外側の部分が、前記ワイヤハーネスに固定されることを特徴とする。 In order to achieve the above object, a wire harness clamp according to claim 1 includes an elongated flat plate-like substrate portion capable of fixing the wire harness to one surface, and the other surface opposite to the one surface of the substrate portion. A locking portion that is provided in a substantially central portion in the longitudinal direction and is elastically locked by being inserted into a locking hole formed in the attached member; and the other end of the substrate portion at the base end portion of the locking portion A dish-shaped plate that is molded integrally with a surface and is crimped so as to close a gap between the attached member and the base end portion of the locking portion when the locking portion is locked in the locking hole. And the substrate portion has at least a pair of reinforcing ribs erected so as to face each other along the longitudinal direction of the projection portion of the dish-shaped seal member on the one surface. The base plate portion has portions on both outer sides in the longitudinal direction from the pair of reinforcing ribs. Characterized in that it is fixed to the serial wire harness.

また、請求項２に係るワイヤハーネス用クランプは、請求項１に記載のワイヤハーネス用クランプにおいて、前記一対の補強リブは、前記皿状のシール部材の投影部分よりも長手方向両外側まで延びて立設されていることを特徴とする。 Moreover, the clamp for wire harnesses according to claim 2 is the clamp for wire harnesses according to claim 1, wherein the pair of reinforcing ribs extend to both outer sides in the longitudinal direction from the projected portion of the dish-shaped seal member. It is characterized by being erected.

前記構成を有する請求項１に係るワイヤハーネス用クランプでは、基板部のシール部材の投影部分、つまり、シール部材に対向する部分の曲げ強度を、長手方向に沿って立設された相対向する一対の補強リブによって大きくすることができる。これにより、ワイヤハーネスを基板部の一対の補強リブよりも長手方向両外側の部分にテープ巻き等で固定することによって、係止部を被取付部材の係止孔に取り付け後、引き回し作業等によってワイヤハーネスに荷重がかかった状態になっても、基板部の一対の補強リブが形成された部分の撓み量の減少化を図ることができる。従って、係止部を被取付部材の係止孔に取り付け後、引き回し作業等によってワイヤハーネスに荷重がかかった状態になっても、基板部のシール部材に対向する部分の撓みを抑え、シール部材と車体パネル等の被取付部材との密着度を維持し、防水性能の低下を防止することが可能となる。 In the wire harness clamp according to claim 1 having the above-described configuration, the bending strength of the projected portion of the sealing member of the substrate portion, that is, the portion facing the sealing member, is set to be opposed to each other along the longitudinal direction. The reinforcing rib can be enlarged. As a result, the wire harness is fixed to the outer portions in the longitudinal direction from the pair of reinforcing ribs of the substrate portion by tape winding or the like. Even when a load is applied to the wire harness, it is possible to reduce the amount of bending of the portion of the substrate portion where the pair of reinforcing ribs are formed. Therefore, after the locking portion is attached to the locking hole of the mounted member, even when the load is applied to the wire harness due to the routing operation or the like, the bending of the portion facing the sealing member of the substrate portion is suppressed, and the sealing member It is possible to maintain the close contact between the vehicle body panel and the mounted member and prevent the waterproof performance from deteriorating.

また、請求項２に係るワイヤハーネス用クランプでは、一対の補強リブは、シール部材の投影部分よりも長手方向両外側まで延びて立設されているため、基板部のシール部材の投影部分よりも外側の部分まで、つまり、シール部材に対向する部分よりも外側の部分までの曲げ強度を、長手方向に沿って立設された相対向する一対の補強リブによって大きくすることができる。これにより、ワイヤハーネスを基板部の一対の補強リブよりも長手方向両外側の部分にテープ巻き等で固定することによって、係止部を被取付部材の係止孔に取り付け後、引き回し作業等によってワイヤハーネスに荷重がかかった状態になっても、基板部のシール部材に対向する部分の撓みを更に抑え、シール部材と車体パネル等の被取付部材との密着度を維持し、防水性能の低下を確実に防止することが可能となる。 Further, in the wire harness clamp according to claim 2, the pair of reinforcing ribs are erected so as to extend to both outer sides in the longitudinal direction from the projected portion of the seal member. The bending strength up to the outer portion, that is, the portion outside the portion facing the seal member can be increased by a pair of opposing reinforcing ribs erected along the longitudinal direction. As a result, the wire harness is fixed to the outer portions in the longitudinal direction from the pair of reinforcing ribs of the substrate portion by tape winding or the like. Even when a load is applied to the wire harness, the bending of the portion of the board facing the sealing member is further suppressed, the degree of adhesion between the sealing member and the mounted member such as the vehicle body panel is maintained, and the waterproof performance is reduced. Can be reliably prevented.

As shown in FIG. A substantially I-shaped insertion head 11 and a distal end portion of the insertion head 11 are extended obliquely outward from both sides in the longitudinal direction of the substrate portion 3 toward the substrate portion 3, toward the insertion head 11 side. It is comprised from a pair of elastic locking piece 12 which can be elastically deformed in the direction to adjoin. Each of the elastic locking pieces 12 is formed in a substantially vertically long square shape when viewed from the front, and is engaged with a locking hole 101 (see FIG. 5) of the attached member 100 at the front end portion on the side of the substrate portion 3 as described later. A locking projection 13 having a substantially triangular side cross section is provided to protrude outward at a predetermined height.

また、基板部３の長手方向に沿った両側面部には、後述のシール部材７の横長皿状のリップ部８の投影形状にほぼ重なるように外側方向に延出された一対の張出部１４、１４が設けられている。
また、基板部３の係止部２が設けられた片側面には、係止部２の投影形状の周縁部分から基板部３の長手方向の各端縁部までの約１／３の部分において、それぞれ全幅に渡って所定高さ（例えば、約０．７ｍｍの高さである。）低くなった段差部１５が形成されている。 Further, a pair of overhanging portions 14 extending outwardly so as to substantially overlap a projected shape of a horizontally long dish-shaped lip portion 8 of a seal member 7 to be described later is formed on both side surface portions along the longitudinal direction of the substrate portion 3. , 14 are provided.
Further, on one side surface of the board part 3 where the locking part 2 is provided, in a portion of about 1/3 from the projected peripheral edge part of the locking part 2 to each edge part in the longitudinal direction of the board part 3 The step portions 15 are formed to be lower by a predetermined height (for example, a height of about 0.7 mm) over the entire width.

また、段差部１５の長手方向外側の各端縁部から基板部３の長手方向の各端縁部までの約１／２の部分において、幅方向中央部から全幅の約半分の幅寸法で、所定高さ（例えば、約０．７ｍｍの高さである。）低くなった各段差部１６が形成されている。また、各段差部１６の中央部には、断面円形の各貫通孔１７が穿設されている。
また、基板部３は、係止部２が設けられた片側面の平面視長手方向の両側端縁部において、後述のように被取付部材１００に当接される各当接部１８、１８が、全幅に渡って、所定高さ（例えば、高さ約１．５ｍｍ〜２ｍｍである。）突設されている。 In addition, in about a half portion from each edge portion on the outer side in the longitudinal direction of the step portion 15 to each edge portion in the longitudinal direction of the substrate portion 3, the width dimension is about half of the full width from the center portion in the width direction. Each step 16 having a predetermined height (for example, a height of about 0.7 mm) is formed. Further, each through hole 17 having a circular cross section is formed in the center of each stepped portion 16.
Further, the substrate portion 3 has contact portions 18 and 18 that are in contact with the attached member 100 as will be described later, at both side edge portions in the longitudinal direction of one side surface where the locking portion 2 is provided. A predetermined height (for example, a height of about 1.5 mm to 2 mm) is provided over the entire width.

また、基板部３の係止部２が設けられていない裏側面（図２中、上側面である。）には、基板部３の長手方向に沿った両側縁部に一対の補強リブ２１が所定高さ（例えば、約１ｍｍ〜２ｍｍの高さである。）立設されている。尚、段差部１５の厚さと補強リブ２１の高さとの合計寸法は、基板部３の長手方向両端部のビニールテープ５等が巻回される部分の厚さ寸法よりも大きくなるように形成されている。 Further, a pair of reinforcing ribs 21 are provided on both side edges along the longitudinal direction of the substrate portion 3 on the back side surface (the upper side surface in FIG. 2) where the locking portion 2 of the substrate portion 3 is not provided. A predetermined height (for example, a height of about 1 mm to 2 mm) is provided. In addition, the total dimension of the thickness of the step portion 15 and the height of the reinforcing rib 21 is formed to be larger than the thickness dimension of the portion around which the vinyl tape 5 or the like at both ends in the longitudinal direction of the substrate portion 3 is wound. ing.

また、基板部３には、係止部２を被取付部材１００に係止したときに、係止部２の基端部周囲と被取付部材１００との隙間を塞ぐように圧着される横長皿状のリップ部８が中央に形成されたシール部材７が、段差部１５及び各段差部１６の面と一体に成形されている。例えば、シール部材７は、エラストマ樹脂等のシールに適した柔軟性を有する素材にて、２色成形等により、基板部３と一体に成形されている。 Further, when the locking portion 2 is locked to the mounted member 100, the horizontally long plate that is crimped to the substrate portion 3 so as to close the gap between the base end portion of the locking portion 2 and the mounted member 100. A seal member 7 having a lip portion 8 formed at the center is formed integrally with the surface of the step portion 15 and each step portion 16. For example, the seal member 7 is made of a material having flexibility suitable for sealing, such as an elastomer resin, and is integrally formed with the substrate portion 3 by two-color molding or the like.

このシール部材７は、基板部３と一体化されている平板部９と、係止部２の基端部の外周部において横長皿状をしたリップ部８とを備えている。また、リップ部８は、横長皿状の外側リップ８Ａと、この外側リップ８Ａの内側に設けられた横長皿状の内側リップ８Ｂとから構成されている。そして、外側リップ８Ａ及び内側リップ８Ｂは、外方に向かって広がり、係止部２の各係止突起１３の外側突出端に対向する高さまで突出するように設けられている。 The seal member 7 includes a flat plate portion 9 integrated with the substrate portion 3 and a lip portion 8 having a horizontally long plate shape at the outer peripheral portion of the base end portion of the locking portion 2. The lip portion 8 is composed of a horizontally long dish-shaped outer lip 8A and a horizontally long dish-shaped inner lip 8B provided inside the outer lip 8A. The outer lip 8 </ b> A and the inner lip 8 </ b> B are provided so as to expand outward and to protrude to a height that faces the outer protruding end of each locking protrusion 13 of the locking portion 2.

次に、上記のように構成されたワイヤハーネス用クランプ１を被取付部材１００の係止孔１０１に差し込んで使用する使用状態について図５に基づいて説明する。図５はワイヤハーネス用クランプ１の使用状態を説明する一部切り欠き側面図である。
図５に示すように、先ず、ワイヤハーネス４を基板部３の係止部２が設けられていない裏側面に押し付けた状態で、基板部３の各補強リブ２１が形成されていない長手方向両端部分とワイヤハーネス４に、ビニールテープ５等を巻き付けて固定する。 Next, a usage state in which the wire harness clamp 1 configured as described above is used by being inserted into the locking hole 101 of the attached member 100 will be described with reference to FIG. FIG. 5 is a partially cutaway side view for explaining the usage state of the wire harness clamp 1.
As shown in FIG. 5, first, in the state where the wire harness 4 is pressed against the back side surface of the board part 3 where the locking part 2 is not provided, both longitudinal ends of the board part 3 where the reinforcing ribs 21 are not formed. A vinyl tape 5 or the like is wound around the portion and the wire harness 4 and fixed.

その後、車体パネル等の被取付部材１００に穿設された係止孔１０１に係止部２の嵌入頭部１１を差し込む。これによって一対の弾性係止片１２が内側に撓んで係止孔１０１を通過し、各係止突起１３の内方側に傾斜した基板部３側の傾斜面が係止孔１０１の縁に弾性的に当接して、係止部２が係止孔１０１に弾性的に係止される。また、基板部３の長手方向両端縁部に突設された各当接部１８が被取付部材１００の下面に当接される。 Thereafter, the fitting head portion 11 of the locking portion 2 is inserted into the locking hole 101 formed in the attached member 100 such as a vehicle body panel. As a result, the pair of elastic locking pieces 12 bend inward and pass through the locking holes 101, and the inclined surfaces on the side of the substrate portion 3 that are inclined inwardly of the locking projections 13 are elastic to the edges of the locking holes 101. The locking portion 2 is elastically locked to the locking hole 101. In addition, each contact portion 18 projecting from both edge portions in the longitudinal direction of the substrate portion 3 is in contact with the lower surface of the attached member 100.

また、シール部材７のリップ部８の各リップ８Ａ、８Ｂの外周縁部分は、弾性変形して係止孔１０１の周縁部に圧着される。従って、係止孔１０１からの水の侵入防止、つまり、被取付部材１００の上下面間の防水性が確保される。
また、基板部３の中央部分の曲げ強度、つまり、係止部２の基端部の周縁部分における曲げ強度は、一対の補強リブ２１及び各張出部１４によって、ビニールテープ５等が巻き付けられている部分の曲げ強度よりも大きくなっている。 In addition, the outer peripheral edge portions of the lips 8A and 8B of the lip portion 8 of the seal member 7 are elastically deformed and are crimped to the peripheral edge portion of the locking hole 101. Therefore, the intrusion prevention of water from the locking hole 101, that is, the waterproof property between the upper and lower surfaces of the attached member 100 is ensured.
Further, the bending strength of the central portion of the substrate portion 3, that is, the bending strength at the peripheral edge portion of the base end portion of the locking portion 2 is wound around the vinyl tape 5 or the like by the pair of reinforcing ribs 21 and the overhang portions 14. It is larger than the bending strength of the part.

このため、図５に示すように、ワイヤハーネス用クランプ１を被取付部材１０１に取り付け後、引き回し作業等によってワイヤハーネス４に荷重がかかった状態になっても、基板部３の一対の補強リブ２１が形成された部分の長手方向外側部分、つまり、ビニールテープ５等が巻き付けられた部分が撓んで、各補強リブ２１及び各張出部１４に挟まれた中央部分の撓み量の減少化を図ることができる。 For this reason, as shown in FIG. 5, even after the wire harness clamp 1 is attached to the attached member 101, the pair of reinforcing ribs of the substrate portion 3 even if the wire harness 4 is loaded by a routing operation or the like. The outer portion in the longitudinal direction of the portion formed with 21, that is, the portion around which the vinyl tape 5 or the like is wound is bent, and the amount of bending of the central portion sandwiched between the reinforcing ribs 21 and the overhang portions 14 is reduced. Can be planned.

従って、係止部２を被取付部材１００の係止孔１０１に取り付け後、引き回し作業等によってワイヤハーネス４に荷重がかかった状態になっても、シール部材７のリップ部８に対向する基板部３の中央部分の撓みを抑え、シール部材７のリップ部８と車体パネル等の被取付部材１００との密着度を維持し、防水性能の低下を防止することが可能となる。 Accordingly, after the locking portion 2 is attached to the locking hole 101 of the mounted member 100, the substrate portion that faces the lip portion 8 of the seal member 7 even when a load is applied to the wire harness 4 due to a routing operation or the like. 3, the degree of adhesion between the lip portion 8 of the seal member 7 and the mounted member 100 such as the vehicle body panel can be maintained, and the deterioration of the waterproof performance can be prevented.

次に、実施例２に係るワイヤハーネス用クランプ３１について図６及び図７に基づいて説明する。尚、以下の説明、図６及び図７において、上記図１乃至図５の実施例１に係るワイヤハーネス用クランプ１の構成等と同一符号は、該実施例１に係るワイヤハーネス用クランプ１の構成等と同一あるいは相当部分を示すものである。

実施例２に係るワイヤハーネス用クランプ３１の構成は、上記実施例１に係るワイヤハーネス用クランプ１の構成とほぼ同じ構成である。
但し、図６に示すように、ワイヤハーネス用クランプ３１は、係止部２が設けられていない裏側面（図６中、上側面である。）に、上記一対の補強リブ２１に替えて、シール部材７の横長皿状のリップ部８に対向する平面視長四角形の対向部分３２の厚さが、この対向部分３２の長手方向両外側部分の厚さよりも全幅に渡って、所定高さ（例えば、約１ｍｍ〜２ｍｍの高さである。）大きくなるように形成されている。 The configuration of the wire harness clamp 31 according to the second embodiment is substantially the same as the configuration of the wire harness clamp 1 according to the first embodiment.
However, as shown in FIG. 6, the wire harness clamp 31 is replaced with the pair of reinforcing ribs 21 on the back side surface (the upper side surface in FIG. 6) where the locking portion 2 is not provided. The thickness of the opposed portion 32 having a rectangular shape in plan view facing the horizontally-long dish-shaped lip portion 8 of the seal member 7 has a predetermined height (over the entire width of the opposite portion 32 in the longitudinal direction). For example, the height is about 1 mm to 2 mm.) It is formed to be large.

また、基板部３の係止部２が設けられていない裏側面には、対向部分３２の長手方向両外側部分のビニールテープ５等が巻回される部分に、この対向部分３２と同じ高さになるように、基板部３の長手方向に対して直角方向の全幅に渡って立設されて、ワイヤハーネス４に当接する幅狭の当接用リブ３３がそれぞれ一対ずつ設けられている。 In addition, on the back side surface of the substrate portion 3 where the engaging portion 2 is not provided, the portion where the vinyl tape 5 or the like on the both outer sides in the longitudinal direction of the facing portion 32 is wound is the same height as the facing portion 32. As shown, a pair of narrowing ribs 33 that stand up over the entire width in the direction perpendicular to the longitudinal direction of the substrate portion 3 and abut against the wire harness 4 are provided.

次に、上記のように構成されたワイヤハーネス用クランプ３１を被取付部材１００の係止孔１０１に差し込んで使用する使用状態について図７に基づいて説明する。
図７に示すように、先ず、ワイヤハーネス４を基板部３の係止部２が設けられていない裏側面に形成された各当接用リブ３３と対向部分３２とに押し付けた状態で、基板部３の対向部分３２が形成されていない長手方向両端部分とワイヤハーネス４に、ビニールテープ５等を巻き付けて固定する。 Next, a usage state in which the wire harness clamp 31 configured as described above is used by being inserted into the locking hole 101 of the attached member 100 will be described with reference to FIG.
As shown in FIG. 7, first, in the state where the wire harness 4 is pressed against each abutment rib 33 and the facing portion 32 formed on the back side surface of the substrate portion 3 where the locking portion 2 is not provided. A vinyl tape 5 or the like is wound around and fixed to both ends in the longitudinal direction where the facing portion 32 of the portion 3 is not formed and the wire harness 4.

その後、車体パネル等の被取付部材１００に穿設された係止孔１０１に係止部２の嵌入頭部１１を差し込んで、係止部２を係止孔１０１に弾性的に係止する。また、基板部３の長手方向両端縁部に突設された各当接部１８が被取付部材１００の下面に当接される。
また、シール部材７のリップ部８の各リップ８Ａ、８Ｂの外周縁部分は、弾性変形して係止孔１０１の周縁部に圧着される。従って、係止孔１０１からの水の侵入防止、つまり、被取付部材１００の上下面間の防水性が確保される。 Thereafter, the fitting head 11 of the locking portion 2 is inserted into the locking hole 101 formed in the attached member 100 such as a vehicle body panel, and the locking portion 2 is elastically locked to the locking hole 101. In addition, each contact portion 18 projecting from both edge portions in the longitudinal direction of the substrate portion 3 is in contact with the lower surface of the attached member 100.
In addition, the outer peripheral edge portions of the lips 8A and 8B of the lip portion 8 of the seal member 7 are elastically deformed and are crimped to the peripheral edge portion of the locking hole 101. Therefore, the intrusion prevention of water from the locking hole 101, that is, the waterproof property between the upper and lower surfaces of the attached member 100 is ensured.

また、基板部３の中央部分の曲げ強度、つまり、係止部２の基端部の周縁部分における曲げ強度は、対向部分３２及び各張出部１４によって、ビニールテープ５等が巻き付けられている部分の曲げ強度よりも大きくなっている。 Further, the bending strength of the central portion of the substrate portion 3, that is, the bending strength at the peripheral edge portion of the base end portion of the locking portion 2, the vinyl tape 5 or the like is wound by the facing portion 32 and each overhanging portion 14. It is larger than the bending strength of the part.

このため、図７に示すように、ワイヤハーネス用クランプ３１を被取付部材１０１に取り付け後、引き回し作業等によってワイヤハーネス４に荷重がかかった状態になっても、基板部３の対向部分３２が形成された部分の長手方向外側部分、つまり、ビニールテープ５等が巻き付けられた部分が撓んで、対向部分３２及び各張出部１４に挟まれた中央部分の撓み量の減少化を図ることができる。 For this reason, as shown in FIG. 7, even when the wire harness clamp 31 is attached to the attachment member 101 and the wire harness 4 is loaded by a routing operation or the like, the opposing portion 32 of the board portion 3 is The outer portion in the longitudinal direction of the formed portion, that is, the portion around which the vinyl tape 5 or the like is wound bends, and the amount of bending at the center portion sandwiched between the opposed portion 32 and each overhang portion 14 can be reduced. it can.

次に、実施例３に係るワイヤハーネス用クランプ４１について図８及び図９に基づいて説明する。尚、以下の説明、図８及び図９において、上記図１乃至図５の実施例１に係るワイヤハーネス用クランプ１の構成等と同一符号は、該実施例１に係るワイヤハーネス用クランプ１の構成等と同一あるいは相当部分を示すものである。
図８は実施例３に係るワイヤハーネス用クランプ４１の係止部２を下側にした状態の外観斜視図である。図９は実施例３に係るワイヤハーネス用クランプ４１の使用状態を説明する一部切り欠き側面図である。 Next, the wire harness clamp 41 according to the third embodiment will be described with reference to FIGS. In the following description and FIGS. 8 and 9, the same reference numerals as those of the wire harness clamp 1 according to the first embodiment shown in FIGS. 1 to 5 denote the wire harness clamp 1 according to the first embodiment. It shows the same or corresponding parts as the configuration.
FIG. 8 is an external perspective view of the state in which the locking portion 2 of the wire harness clamp 41 according to the third embodiment is on the lower side. FIG. 9 is a partially cutaway side view illustrating the usage state of the wire harness clamp 41 according to the third embodiment.

実施例３に係るワイヤハーネス用クランプ４１の構成は、上記実施例１に係るワイヤハーネス用クランプ１の構成とほぼ同じ構成である。
但し、図８に示すように、ワイヤハーネス用クランプ４１は、係止部２が設けられていない裏側面（図８中、上側面である。）に、上記一対の補強リブ２１に替えて、シール部材７の横長皿状の外側リップ部８Ａの投影部分の長手方向両端縁部において、全幅に渡って，所定深さ（例えば、厚さの約半分の深さである。）の断面半円形状の一対の溝部４２が形成されている。 The configuration of the wire harness clamp 41 according to the third embodiment is substantially the same as the configuration of the wire harness clamp 1 according to the first embodiment.
However, as shown in FIG. 8, the wire harness clamp 41 is replaced with the pair of reinforcing ribs 21 on the back side surface (the upper side surface in FIG. 8) where the locking portion 2 is not provided. A semicircular cross-section having a predetermined depth (for example, about half the thickness) over the entire width at both ends in the longitudinal direction of the projected portion of the horizontally long dish-shaped outer lip portion 8A of the seal member 7. A pair of shaped groove portions 42 is formed.

次に、上記のように構成されたワイヤハーネス用クランプ４１を被取付部材１００の係止孔１０１に差し込んで使用する使用状態について図９に基づいて説明する。
図９に示すように、先ず、ワイヤハーネス４を基板部３の係止部２が設けられていない裏側面に押し付けた状態で、基板部３の各溝部４２が形成されていない長手方向両端部分とワイヤハーネス４に、ビニールテープ５等を巻き付けて固定する。 Next, a use state in which the wire harness clamp 41 configured as described above is used by being inserted into the locking hole 101 of the attached member 100 will be described with reference to FIG. 9.
As shown in FIG. 9, first, both end portions in the longitudinal direction where the groove portions 42 of the substrate portion 3 are not formed in a state where the wire harness 4 is pressed against the back side surface of the substrate portion 3 where the engaging portion 2 is not provided. The vinyl harness 5 is wrapped around the wire harness 4 and fixed.

また、基板部３の中央部分における長手方向端縁部の曲げ強度、つまり、各溝部４２における曲げ強度は、中央部分の曲げ強度及びビニールテープ５等が巻き付けられている部分の曲げ強度よりも小さくなっている。 Further, the bending strength of the edge portion in the longitudinal direction in the central portion of the substrate portion 3, that is, the bending strength in each groove portion 42 is smaller than the bending strength of the central portion and the bending strength of the portion around which the vinyl tape 5 or the like is wound. It has become.

このため、図９に示すように、ワイヤハーネス用クランプ４１を被取付部材１０１に取り付け後、引き回し作業等によってワイヤハーネス４に荷重がかかった状態になっても、基板部３の中央部分の長手方向外側端縁部に形成された溝部４２を境にしてビニールテープ５等が巻き付けられた部分だけが撓んで、中央部分の撓み量の減少化を図ることができる。 For this reason, as shown in FIG. 9, after the wire harness clamp 41 is attached to the attached member 101, even if a load is applied to the wire harness 4 by a routing operation or the like, Only the portion around which the vinyl tape 5 or the like is wound is bent at the groove portion 42 formed on the outer edge in the direction, so that the amount of bending at the center portion can be reduced.
