Description

本発明は電子機器等のシャーシに電子部品やケーブル等を実装するために用いる固定具に関し、特にシャーシの表面側からの取り外しを容易に行うことが可能な固定具に関するものである。   The present invention relates to a fixture used for mounting an electronic component, a cable, or the like on a chassis of an electronic device or the like, and more particularly to a fixture that can be easily detached from the surface side of the chassis.

電子機器を組み立てる場合には、パネル、シャーシ、基板等の組立基板(以下、これらをシャーシと称する)に電子部品を取り付けたり、ケーブル等の配線部品を延設配置する必要があり、そのために実装用部品が用いられる。例えば、シャーシの表面に沿って複数本のケーブルを並列状態に延設配置する場合には、複数本のケーブルを結束した状態でシャーシへの取着を行うケーブルタイが用いられる。従来のケーブルタイの一例を図8に示す。ケーブルタイ1Aは、複数本のケーブルを結束するために他端が自由端とされたバンド41と、前記バンド41の基端が連結され、バンド41を先端から挿通させたときに当該バンド41に設けられた図には表れない鋸歯に嵌合してバンド41の抜け出しを防止する係止歯を備えるロック部42を備えている。また、前記ロック部42の下面には嵌合部50が設けられており、この嵌合部50は、下方に突出したポスト51の両側に矢尻型に張り出した一対の嵌合片52を有しており、シャーシ2の表面側から嵌合片52をシャーシ2に設けた嵌合穴3内に挿入すると、一対の嵌合片52は弾性により縮径されて嵌合穴3を通され、通過後は弾性復帰して拡径することで嵌合片52の末端部に設けた段部52aが嵌合穴3の内縁部に嵌合する。また、嵌合片52に対向して設けられているハ字状をした一対の脚片55がシャーシ2の表面側に当接することで、前記段部52aと嵌合穴3との嵌合状態が保持される。このような嵌合部を備える固定具としては、例えば特許文献1に記載のものがある。
特開平9−242936号公報
When assembling electronic equipment, it is necessary to attach electronic parts to an assembly board such as a panel, chassis, and board (hereinafter referred to as a chassis) and to arrange wiring parts such as cables in an extended manner. Parts are used. For example, when a plurality of cables are arranged to extend in parallel along the surface of the chassis, a cable tie that attaches to the chassis in a state in which the plurality of cables are bundled is used. An example of a conventional cable tie is shown in FIG. The cable tie 1A has a band 41 whose other end is a free end for bundling a plurality of cables and a base end of the band 41, and the band 41 is inserted into the band 41 when the band 41 is inserted from the tip.

Japanese Patent Laid-Open No. 9-242936

ところで、近年における家電製品、OA機器、自動車、電子機器全般において環境問題の解決策として環境配慮型製品の販売が義務付けられている中で、例えば、電子機器に内装したプリント基板や配線を電子機器のシャーシやパネル等から解体してリユース(再利用)することが要求されている。特に、解体作業を容易に行うために、工具等を用いることなく容易に解体することが要求されている。しかしながら、図8に示した従来の嵌合部の構造では、嵌合片52を手や工具等を用いて縮径させてシャーシ2の嵌合穴3から引き出すことが必要であり、この場合嵌合片52が小さくて掴み難いためにその操作が困難であるという問題がある。また、シャーシ2の裏面側で嵌合片32を縮径させる必要があり、作業性が悪いという問題もある。   By the way, in recent years home appliances, office automation equipment, automobiles, and electronic devices are generally required to sell environmentally conscious products as a solution to environmental problems. For example, printed circuit boards and wirings embedded in electronic devices are used as electronic devices. It is required to be disassembled and reused from the chassis and panels. In particular, in order to easily perform the dismantling work, it is required to dismantle easily without using a tool or the like. However, in the structure of the conventional fitting portion shown in FIG. 8, it is necessary to reduce the diameter of the fitting piece 52 using a hand or a tool and pull it out from the fitting hole 3 of the chassis 2. There is a problem that the operation is difficult because the combined piece 52 is small and difficult to grasp. Moreover, it is necessary to reduce the diameter of the fitting piece 32 on the back surface side of the chassis 2, and there is a problem that workability is poor.

このような問題に対し、本願出願人は特願2003−72332において、シャーシの表面側から容易に着脱を可能にした固定具を提案している。この固定具はケーブルクランプに用いた例を示しており、図9に嵌合部の構造をケーブルクランプ1Bに適用した例を示している。基本的な構成は図8のケーブルタイ1Aの嵌合部50の構成と同じであるため等価な部分には同一符号を付しているが、ケーブルを支承するための枠状をした保持部10の支承片11の下面からポスト51が下方に突出され、このポスト51の先端に一対の嵌合片52を有している。これらの嵌合片52の各先端には連結片53を介して支承片11の両側に沿って上方に延長された解除片54が形成されている。そのため、シャーシ2の嵌合穴3に嵌合部50を嵌合した状態においても、図9に矢印で示すようにシャーシ2の表面側から一対の解除片54を指操作して内側に変形させることで、この解除片54に連結片53を介して連結されている嵌合片52を一体的に内側に変形してその径寸法を縮小することができ、固定具をシャーシ2の嵌合穴3から取り外すことが可能になる。   In response to such a problem, the applicant of the present application has proposed a fixture that can be easily attached and detached from the surface side of the chassis in Japanese Patent Application No. 2003-72332. This fixing tool shows the example used for the cable clamp, and the example which applied the structure of the fitting part to the cable clamp 1B in FIG. 9 is shown. Since the basic configuration is the same as the configuration of the fitting portion 50 of the cable tie 1A in FIG. 8, the same reference numerals are given to equivalent portions, but the frame-shaped holding portion 10 for supporting the cable. A post 51 protrudes downward from the lower surface of the support piece 11 and has a pair of fitting pieces 52 at the tip of the post 51. A release piece 54 extending upward along both sides of the support piece 11 is formed at each end of the fitting piece 52 via a connecting piece 53. Therefore, even when the fitting portion 50 is fitted in the fitting hole 3 of the chassis 2, the pair of release pieces 54 are deformed inward by finger operation from the surface side of the chassis 2 as shown by arrows in FIG. Thus, the fitting piece 52 connected to the release piece 54 via the connecting piece 53 can be integrally deformed inward to reduce its diameter, and the fixture can be used as a fitting hole in the chassis 2. 3 can be removed.

しかし、この提案した固定具について本発明者がさらに検討を加えたところ、改善すべき点が明らかになった。これは、シャーシ2に装着された固定具は、通常では保持部10の両端面は両嵌合片を結ぶ線に対して垂直な方向に向けられているが、支持しているケーブルやその他の部品に外力が加えられたときに、図10(a)のように保持部10が水平方向の時計方向に捩じり変形されると、保持部10が大きな角度まで回転され、ポスト51が嵌合片52の内側に当接される状態となる。そのため、この状態で解除片54を内側に向けて変形しても、嵌合片52は当接状態にあるポスト51によって内側方向への変形、すなわち縮径が阻止されてしまい、嵌合片52を嵌合穴3から引き出すことが困難になる。これは図10(b)に示すように反対方向の反時計方向に捩じり回転された場合も同じである。   However, when the inventor further examined the proposed fixture, points to be improved became clear. This is because the fixing device mounted on the chassis 2 is normally oriented so that both end faces of the holding portion 10 are perpendicular to the line connecting both fitting pieces, When an external force is applied to the part, if the holding portion 10 is twisted and deformed clockwise in the horizontal direction as shown in FIG. 10A, the holding portion 10 is rotated to a large angle and the post 51 is fitted. It will be in the state contact | abutted to the inner side of the joining piece 52. FIG. Therefore, even if the release piece 54 is deformed inward in this state, the fitting piece 52 is prevented from being deformed inward, that is, reduced in diameter by the post 51 in a contact state. It becomes difficult to pull out from the fitting hole 3. This is the same when twisted and rotated counterclockwise as shown in FIG. 10B.

本発明の目的は、このような固定具における捩じり方向での変形が要因となってシャーシからの取り外しが困難になることを未然に防止した固定具を提供するものである。   An object of the present invention is to provide a fixture that prevents the fixture from being difficult to be removed from the chassis due to deformation in the twisting direction.

本発明は、シャーシに部品を保持させるための保持部と、保持部と一体に設けられ、シャーシに設けられた嵌合穴に嵌合して保持部をシャーシに固定するための嵌合部とを備える固定具において、嵌合部は保持部の一側から下方に向けて突出されたポストと、ポストの先端部に設けられ、外径方向に弾性変形して嵌合穴に嵌合される矢尻型をした一対の嵌合片と、嵌合片の先端部からそれぞれ保持部の両側面に沿って延設され、手操作されたときに一対の嵌合片を内径方向に弾性変形して嵌合穴との嵌合から離脱させるための一対の解除片と、解除片の一部に基端部が連結され先端部がシャーシの表面に当接可能な一対の脚片と、ポストまたは保持部の少なくとも一方に形成され、ポスト又は保持部が解除片に対して捩じり方向に回転されたときに嵌合片あるいは解除片に当接してその回転量を規制するためのストッパとを備えることを特徴とする。   The present invention includes a holding portion for holding a component in the chassis, a fitting portion that is provided integrally with the holding portion, and that fits into a fitting hole provided in the chassis and fixes the holding portion to the chassis. In the fixing device, the fitting portion is provided at a post projecting downward from one side of the holding portion, and at a tip portion of the post, and is elastically deformed in the outer diameter direction and fitted into the fitting hole. A pair of arrowhead-shaped fitting pieces, and extending from the front end of the fitting piece along both side surfaces of the holding portion, and when manually operated, the pair of fitting pieces are elastically deformed in the inner diameter direction. A pair of release pieces for disengagement from the fitting hole, a pair of leg pieces whose base end portion is connected to a part of the release pieces and whose distal end portion can contact the surface of the chassis, and a post or holding Formed on at least one of the parts, and the post or the holding part is rotated in the twisting direction with respect to the release piece In contact with the fitting piece or release piece to come, characterized in that it comprises a stopper for restricting the amount of rotation.

本発明によれば、嵌合部に設けた一体の解除片を両外側から指で摘んで嵌合片を内径方向に弾性変形させることでシャーシの嵌合穴から固定具を容易に取り外すことが可能になる。また、保持部に加えられた外力によって保持部が捩じり回転された場合にストッパにより保持部またはポストの回転量を抑制し、ポストと嵌合片あるいは解除片との干渉を防止し、解除片による固定具の取り外しを確保することが可能になる。   According to the present invention, it is possible to easily remove the fixture from the fitting hole of the chassis by holding the integral release piece provided in the fitting portion with fingers from both outsides and elastically deforming the fitting piece in the inner diameter direction. It becomes possible. In addition, when the holding part is twisted and rotated by an external force applied to the holding part, the amount of rotation of the holding part or post is suppressed by the stopper to prevent interference between the post and the fitting piece or release piece, and release It becomes possible to ensure the removal of the fixture by the piece.

本発明におけるストッパは保持部の捩じり方向の一方向の回転量を規制する第1のストッパがポストに形成され、当該捩じり方向の反対方向の回転量を規制する第2のストッパが保持部に形成されることが好ましい。   In the stopper according to the present invention, a first stopper that restricts the amount of rotation of the holding portion in one direction of twisting is formed on the post, and a second stopper that restricts the amount of rotation in the opposite direction of the twisting direction is provided. It is preferable to be formed in the holding part.

次に、本発明の実施形態を図面を参照して説明する。図1は本発明の固定具をシャーシの表面に沿ってケーブルを延設支持するためのケーブルクランプに適用した実施例1の斜視図である。また、図2(a),(b)は正面図と側面図、図3(a),(b)は図2(a)のAA線拡大断面図、BB線拡大断面図である。これらの図において、ケーブルクランプは1は、図外のケーブルをクランプするための保持部10と、この保持部10をシャーシ2に取着するために、当該シャーシ2に設けられた嵌合穴3に嵌合される嵌合部20とで構成されており、両部は樹脂成形により一体に形成されている。   Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a first embodiment in which the fixture of the present invention is applied to a cable clamp for extending and supporting a cable along the surface of a chassis. FIGS. 2A and 2B are a front view and a side view, and FIGS. 3A and 3B are an AA line enlarged cross-sectional view and a BB line enlarged cross-sectional view of FIG. In these drawings, a cable clamp 1 includes a holding portion 10 for clamping a cable (not shown), and a fitting hole 3 provided in the chassis 2 for attaching the holding portion 10 to the chassis 2. And both parts are integrally formed by resin molding.

前記保持部10は、ほぼ上向きU字型をした支承片11と、この支承片11の一端に連結されて前記支承片11の開口を開閉可能にされ、先端に小U字型をしたロック片13を有するヒンジ片12と、前記支承片11の他端に設けられて前記ロック片13を着脱可能にロックするロック体14とを備えている。この保持部10ではヒンジ片12を開いた状態で開口を通して支持するケーブルを支承片11内に内挿し、その後ヒンジ片12を閉じてロック片13をロック体14に係合することで支承片11からのケーブルの脱落を防止する。また、ロック片13を指で操作してロック体14とのロックを解除することでケーブルを支承片11内から取り出すことが可能である。   The holding portion 10 includes a support piece 11 having a substantially upward U shape, and a lock piece connected to one end of the support piece 11 so as to be able to open and close the opening of the support piece 11 and having a small U shape at the tip. 13 and a lock body 14 provided at the other end of the support piece 11 and detachably locks the lock piece 13. In this holding portion 10, a cable that supports the opening through the opening with the hinge piece 12 opened is inserted into the support piece 11, and then the hinge piece 12 is closed and the lock piece 13 is engaged with the lock body 14 to thereby engage the support piece 11. Prevents cables from falling off. Further, the cable can be taken out from the support piece 11 by operating the lock piece 13 with a finger to release the lock with the lock body 14.

前記嵌合部20は前記支承片11の略中央の下面から所要の長さで下方に突出した概ね細長い板状のポスト21を備えている。前記ポスト21の下側の先端部にはそれぞれ径方向に弾性変形可能な一対の嵌合片22,22が連結されており、全体として矢尻型に形成されている。前記一対の嵌合片22,22の外側面は前記ポスト21を中心とした円弧状にされ、円形の輪郭の一部を構成するようになっている。また、前記一対の嵌合片22,22の拡径された各端部にはそれぞれ板厚の小さい連結片23,23が一体に連結形成されており、当該先端部の外側面には前記連結片23,23と嵌合片22,22との板厚の差に相当する径方向の段部22a,22aが形成されている。   The fitting portion 20 includes a substantially elongated plate-like post 21 that protrudes downward from the lower surface of the substantially center of the support piece 11 by a predetermined length. A pair of fitting pieces 22, 22 that are elastically deformable in the radial direction are connected to the lower end portion of the post 21, and are formed in an arrowhead shape as a whole. The outer side surfaces of the pair of fitting pieces 22 and 22 are formed in a circular arc shape with the post 21 as a center, and constitute a part of a circular outline. In addition, connecting pieces 23 and 23 having a small plate thickness are integrally connected to the end portions of the pair of fitting pieces 22 and 22 whose diameters are enlarged, and the connecting surface is formed on the outer surface of the tip portion. Step portions 22a and 22a in the radial direction corresponding to the difference in plate thickness between the pieces 23 and 23 and the fitting pieces 22 and 22 are formed.

前記一対の連結片23,23の上端部には、それぞれ前記支承片11の両側面に沿って幾分外側に湾曲された状態で上方に向けて延設された一対の解除片24,24が連結されている。また、前記一対の解除片24,24が前記連結片23,23に連結されている箇所には、それぞれ両外方向の幾分下方に向けて傾斜した状態でほぼ真直に突出された一対の脚片25,25が一体に形成されている。この一対の脚片25,25の各先端部は通常では前記嵌合片22,22の段部22a,22aよりもシャーシ2の板厚に対応して若干上方に位置されている。また、前記一対の解除片24,24の上端部24a,24aは若干薄肉に形成されるとともにそれぞれ内側に向けられ、前記支承片11の各外側面に対して若干の間隔をおいて対峙されるように位置されている。   At the upper ends of the pair of connecting pieces 23, 23, there are a pair of release pieces 24, 24 extending upward in a state of being curved somewhat outward along both side surfaces of the support piece 11. It is connected. In addition, a pair of legs projecting substantially straight in a state in which the pair of release pieces 24, 24 are connected to the connecting pieces 23, 23, respectively, in a state of being inclined slightly downward in both outward directions. The pieces 25 and 25 are integrally formed. The tip portions of the pair of leg pieces 25, 25 are usually positioned slightly above the step portions 22a, 22a of the fitting pieces 22, 22 corresponding to the plate thickness of the chassis 2. Further, the upper end portions 24a, 24a of the pair of release pieces 24, 24 are formed to be slightly thin and directed inward, and are opposed to each outer surface of the support piece 11 with a slight gap. Is located so that.

ここで、図4(a)に要部の一部破断斜視図を示すように、前記ポスト21は、その長さ方向の上部の両側縁、換言すれば前記連結片の上端部が対向配置される領域にそれぞれ互いに反対方向を向けてほぼ直角方向に突出された一対の第1ストッパ26,26が一体に形成されている。これらの第1ストッパ26,26は、上端部から所要の長さまでは一定の突出寸法であり、それよりも下側の領域では突出寸法が漸減するようなテーパ状に形成されている。そして、これら第1ストッパ26,26の最大の突出寸法は、前記ポスト21が水平方向に所定の角度まで捩じられて回転されたとき、すなわちこの角度は支承片11の両側部が前記解除片24に当接されることがない角度まで回転されたときに各第1ストッパ26,26がそれぞれ連結片23,23の一側部に当接される寸法に設定されている。   Here, as shown in FIG. 4 (a), which is a partially broken perspective view of the main part, the post 21 is arranged so that both side edges of the upper part in the length direction, in other words, the upper end part of the connecting piece are opposed to each other. A pair of first stoppers 26 and 26 projecting in a substantially right angle direction opposite to each other are formed integrally with each other. The first stoppers 26 and 26 are formed in a tapered shape that has a constant protruding dimension from the upper end portion to a required length and gradually decreases in the lower region. The maximum projecting dimensions of the first stoppers 26 and 26 are such that when the post 21 is rotated by being twisted to a predetermined angle in the horizontal direction, that is, both sides of the support piece 11 are the release pieces. Each of the first stoppers 26 and 26 is set to a size that abuts against one side portion of the connecting pieces 23 and 23 when rotated to an angle that does not abut against 24.

また、図4(b)に同じく要部の一部破断斜視図を示すように、前記保持部10、ここでは前記支承片11の側縁に沿った部分で前記第1ストッパ26,26とは回転方向に反対側でかつ前記ポスト21を中心とした点対称位置にはそれぞれ第2ストッパ15,15が一体に形成されている。これらの第2ストッパ15,15は前記したようにポスト21と共に支承片11が前記所定の角度まで捩じられて回転されたときに前記連結片23,23あるいはこれにつながる解除片24,24の一側部が当接されるように、前記支承片11の幅寸法に基づいて計算された所定位置に設定されている。   Also, as shown in FIG. 4B, a partially broken perspective view of the main part, the first stoppers 26, 26 are defined by the holding part 10, here along the side edge of the support piece 11. Second stoppers 15 and 15 are integrally formed at point-symmetrical positions on the opposite side in the rotational direction and with the post 21 as the center. These second stoppers 15 and 15 are connected to the connecting pieces 23 and 23 or the releasing pieces 24 and 24 connected thereto when the support piece 11 is rotated to the predetermined angle together with the post 21 as described above. It is set at a predetermined position calculated based on the width dimension of the support piece 11 so that one side portion is brought into contact therewith.

以上の構成のケーブルクランプ1によれば、ケーブルクランプ1をシャーシ2の嵌合穴3に取着する際には、嵌合部20をシャーシ2の上面側から嵌合穴3に挿入する。このように挿入することにより、図5(a)のように、嵌合部20の一対の嵌合片22,22は内径方向に弾性変形されて縮径され、嵌合穴3内への挿入を可能にする。そして、嵌合片22,22が嵌合穴3を貫通すると、嵌合片22,22は弾性力によって復元して外径方向に拡径し、段部22a,22aがシャーシ2の下面において嵌合穴3の内縁部に係合する。また、これと同時に一対の脚片25,25の先端部がシャーシ2の表面に弾性的に当接され、嵌合部20を上方に付勢するため、前記段部22a,22aを嵌合穴3の内縁部に対して押圧することになり、係合状態を保持することになる。これにより、ケーブルタイ1を上方に引っ張った場合でも、段部22a,22aと嵌合穴3との係合によって嵌合部20が嵌合穴3から挿脱されることがなく、ケーブルクランプ1をシャーシ2に固定することができる。図6その装着状態の要部の斜視図である。   According to the cable clamp 1 having the above configuration, when the cable clamp 1 is attached to the fitting hole 3 of the chassis 2, the fitting portion 20 is inserted into the fitting hole 3 from the upper surface side of the chassis 2. By inserting in this way, as shown in FIG. 5A, the pair of fitting pieces 22, 22 of the fitting portion 20 is elastically deformed in the inner diameter direction to be reduced in diameter, and inserted into the fitting hole 3. Enable. When the fitting pieces 22, 22 pass through the fitting hole 3, the fitting pieces 22, 22 are restored by elastic force and expanded in the outer diameter direction, and the stepped portions 22 a, 22 a are fitted on the lower surface of the chassis 2. Engage with the inner edge of the hole 3. At the same time, the tip portions of the pair of leg pieces 25, 25 are elastically contacted with the surface of the chassis 2 to urge the fitting portion 20 upward, so that the stepped portions 22a, 22a are fitted into the fitting holes. 3 will be pressed against the inner edge portion, and the engaged state will be maintained. Thus, even when the cable tie 1 is pulled upward, the fitting portion 20 is not inserted into and removed from the fitting hole 3 due to the engagement between the step portions 22a and 22a and the fitting hole 3, and the cable clamp 1 Can be fixed to the chassis 2. 6 is a perspective view of the main part in the mounted state.

しかる上で、図示は省略するが、保持部10のヒンジ片12を開いてシャーシ2の上面上に延設しようとするケーブルを支承片11内にに内挿し、ヒンジ片12を閉じてロック片13をロック体14に係合させることでケーブルを保持してシャーシ2の表面上に延設支持させることになる。なお、先にケーブルを支承片11内に保持させた上で、嵌合部20を嵌合穴3に挿入して嵌合取着するようにしてもよい。   Therefore, although illustration is omitted, the hinge piece 12 of the holding portion 10 is opened and a cable to be extended on the upper surface of the chassis 2 is inserted into the support piece 11, and the hinge piece 12 is closed and the lock piece is closed. By engaging 13 with the lock body 14, the cable is held and extended and supported on the surface of the chassis 2. In addition, after the cable is first held in the support piece 11, the fitting portion 20 may be inserted into the fitting hole 3 to be fitted and attached.

一方、シャーシ2に装着したケーブルクランプ1をシャーシから離脱する際には、図5(b)に示すように、2本の指Fで解除片24,24を両外側から摘み、かつ両側から力を加えて解除片24,24を内側に変形させる。この変形により、同図のように解除片24,24と一体の連結片23,23も内側に向けて変形され、さらに連結片23,23と一体の嵌合片22,22も内側に変形されて縮径され、段部22a,22aが嵌合穴3の内縁部から外れることになる。したがって、そのままケーブルタイ1をシャーシ2の上方に引き上げることで嵌合部20を嵌合穴3から引き抜くことができ、ケーブルクランプ1の取り外しが実現できる。   On the other hand, when the cable clamp 1 attached to the chassis 2 is detached from the chassis, as shown in FIG. 5B, the release pieces 24, 24 are picked from both outsides with two fingers F and force is applied from both sides. To release the release pieces 24, 24 inward. As a result of this deformation, the connecting pieces 23 and 23 integral with the release pieces 24 and 24 are also deformed inward as shown in the figure, and the fitting pieces 22 and 22 integral with the connecting pieces 23 and 23 are also deformed inward. Thus, the stepped portions 22a and 22a are detached from the inner edge of the fitting hole 3. Therefore, by pulling the cable tie 1 up above the chassis 2 as it is, the fitting portion 20 can be pulled out from the fitting hole 3 and the cable clamp 1 can be removed.

ここで、ケーブルクランプ1がシャーシ2に取着されている図5(a)の状態においては、一対の脚片25,25の先端部がシャーシ2の表面に当接されて広がる方向に変形される応力が生じ、一対の解除片24,24が内側に倒れる方向に変形され、解除片24,24の上端部24a,24aが支承片11の両側面に多少の弾性力をもって当接される。そのため、解除片24,24を支点としたてこの作用によって一対の嵌合片22,22には連結片23,23を介して外径方向に広がる応力が加えられるため、嵌合片22,22と嵌合穴3との嵌合力が増大され、ケーブルクランプ1が嵌合穴3から外れ難くなり、外力等によっても容易にシャーシ2から離脱されることはない。また、このとき一対の脚片25,25はシャーシ2の板厚の相違に応じて先端部での変形量が変化され、当該板厚の相違によっても嵌合片22,22との間でシャーシ2を板厚方向に挟んで嵌合状態を確かなものとする。   Here, in the state of FIG. 5A in which the cable clamp 1 is attached to the chassis 2, the distal ends of the pair of leg pieces 25, 25 are deformed so as to be in contact with the surface of the chassis 2 and spread. The pair of release pieces 24, 24 are deformed in a direction to fall inward, and the upper end portions 24a, 24a of the release pieces 24, 24 are brought into contact with both side surfaces of the support piece 11 with some elastic force. For this reason, stress that spreads in the outer diameter direction is applied to the pair of fitting pieces 22 and 22 through the connecting pieces 23 and 23 by the action of the release pieces 24 and 24 as fulcrums. And the fitting force between the fitting hole 3 and the cable clamp 1 are not easily detached from the fitting hole 3 and are not easily detached from the chassis 2 even by an external force or the like. Further, at this time, the pair of leg pieces 25, 25 is changed in the amount of deformation at the tip portion according to the difference in the plate thickness of the chassis 2, and the chassis between the fitting pieces 22, 22 is also affected by the difference in the plate thickness. 2 is sandwiched in the plate thickness direction to ensure a fitted state.

また、同じ状態において、仮にケーブルクランプ1がケーブルを通して伝えられる外力を受け、シャーシ2上で保持部が傾倒された場合でも、支承片11と解除片24,24の上端部24a,24aとは離間されているため、支承部11に引っ張られて解除片24,24が傾倒されることはない。そのため、解除片24,24が内径方向に傾倒されて嵌合片22,22と嵌合穴3との嵌合状態が損なわれることはなく、嵌合部20の離脱が防止される。また、保持部10が傾倒されたときには支承片11は傾倒された側の解除片24の上端部24aに当接されるため、保持部10がそれ以上に傾倒することが抑制されるとともに、解除片24のさらなる傾倒が抑制されることにもなる。   In the same state, even if the cable clamp 1 receives an external force transmitted through the cable and the holding portion is tilted on the chassis 2, the support piece 11 and the upper end portions 24a and 24a of the release pieces 24 and 24 are separated from each other. Therefore, the release pieces 24 and 24 are not tilted by being pulled by the support portion 11. Therefore, the release pieces 24, 24 are tilted in the inner diameter direction and the fitting state between the fitting pieces 22, 22 and the fitting hole 3 is not impaired, and the fitting portion 20 is prevented from being detached. Further, when the holding portion 10 is tilted, the support piece 11 is brought into contact with the upper end 24a of the tilted release piece 24, so that the holding portion 10 is prevented from further tilting and released. Further tilting of the piece 24 is also suppressed.

さらに、同じ状態において、ケーブルを通してケーブルクランプ1の保持部10が水平に一方向(図の反時計方向)に回転された場合には、図7(a)に示すように、支承片11及びポスト21が一体的に回転される。そして、所定の角度だけ回転された時点で一対の第1ストッパ26,26がそれぞれ破線円内に示すように連結片23,23に当接されるため、以降の保持部10及びポスト21の回転は係止される。一方、保持部10が水平に反対方向(時計方向)に回転された場合には、図7(b)に示すように、支承片11に設けた第2ストッパ15,15がそれぞれ破線円内に示すように連結片23,23あるいは解除片24,24の一側部に当接されるため、同様に以降の保持部10及びポスト21の回転は係止される。このように、水平方向の両方向への回転量が抑制された状態では、ポスト21と両嵌合片22,22との間、及び支承片11と両解除片24,24との間に所要の間隔が確保されることになるので、解除片24,24を指操作して内側に変形可能な状態が確保され、この解除片24,24の内側への変形によって嵌合片22,22を縮径し、当該嵌合片22,22と嵌合穴3との嵌合状態を解消し、ケーブルクランプ1をシャーシ2から取り外すことが確保される。   Further, in the same state, when the holding portion 10 of the cable clamp 1 is horizontally rotated in one direction (counterclockwise in the figure) through the cable, as shown in FIG. 21 is rotated integrally. Then, when the pair of first stoppers 26 and 26 are brought into contact with the connecting pieces 23 and 23 as indicated by broken line circles when they are rotated by a predetermined angle, the subsequent rotation of the holding portion 10 and the post 21 is performed. Is locked. On the other hand, when the holding part 10 is rotated horizontally in the opposite direction (clockwise), as shown in FIG. 7B, the second stoppers 15 and 15 provided on the support piece 11 are respectively within the broken line circles. As shown in the figure, since the contact pieces 23 and 23 or one side portion of the release pieces 24 and 24 are in contact with each other, the subsequent rotation of the holding portion 10 and the post 21 is similarly locked. Thus, in a state in which the amount of rotation in both directions in the horizontal direction is suppressed, the required distance between the post 21 and both fitting pieces 22 and 22 and between the support piece 11 and both release pieces 24 and 24 is required. Since the interval is secured, the release pieces 24, 24 are operated by fingers, so that a state in which the release pieces 24, 24 can be deformed inside is secured, and the fitting pieces 22, 22 are contracted by the inside deformation of the release pieces 24, 24. The fitting state between the fitting pieces 22 and 22 and the fitting hole 3 is eliminated, and it is ensured that the cable clamp 1 is removed from the chassis 2.

ここで、前記実施例1で、第1ストッパ26,26及び第2ストッパ15,15をそれぞれ異なる位置に形成しているのは、ケーブルクランプ1を樹脂成形によって製造しているためであり、樹脂成形金型を正面及び背面方向に分離する際にこれら第1及び第2のストッパが分離の障害にならないようにするためである。したがって、金型構造が複雑化することが問題とならないのであれば、第1ストッパ26,26あるいは第2ストッパ15,15のいずれかをそれぞれポスト21の両側部、あるいは保持部10の支承片11の両側部にそれぞれ線対称に配設することも可能である。   Here, in the first embodiment, the first stoppers 26 and 26 and the second stoppers 15 and 15 are formed at different positions because the cable clamp 1 is manufactured by resin molding. This is to prevent the first and second stoppers from becoming an obstacle to separation when separating the molding die in the front and back directions. Accordingly, if there is no problem in complicating the mold structure, either the first stopper 26 or 26 or the second stopper 15 or 15 is attached to both sides of the post 21 or the support piece 11 of the holding part 10. It is also possible to arrange them symmetrically on both sides.

なお、前記実施例1では本発明をケーブルクランプに適用した実施形態を示してたが、保持部の構成が異なる他の固定具についても同様に適用することが可能である。すなわち、嵌合部をシャーシに設けた嵌合穴に嵌合して取着し、保持部において各種部品をシャーシに保持させる各種の固定具についても同様に適用できることは言うまでもない。   In the first embodiment, the embodiment in which the present invention is applied to the cable clamp is shown. However, the present invention can also be applied to other fixing devices having different holding parts. That is, it goes without saying that the present invention can be similarly applied to various fixing devices in which the fitting portion is fitted and attached to a fitting hole provided in the chassis and various components are held by the chassis in the holding portion.
