Description

本発明は、電気配線等を有する平板状ケーブル（例：フィルム状フレキシブルケーブル）を電気的に接続するコネクタに関し、より詳細には、アクチュエータの開閉操作によって、コンタクト部が開閉動作を伴い、それよって、コンタクト部と平板状ケーブルとを接触又は非接触とすることができる電気コネクタに関するものである。   The present invention relates to a connector for electrically connecting a flat cable having electrical wiring or the like (for example, a film-like flexible cable). More specifically, the contact part is accompanied by an opening / closing operation by an opening / closing operation of an actuator, thereby The present invention relates to an electrical connector capable of bringing a contact portion and a flat cable into contact or non-contact.

従来技術では、筐体と、平板状ケーブルを把持するコンタクト部とを備えたコネクタは多数開示されている。その主な構造は、コンタクト部が、連接部を介して接続された２つの対向するビームを有して構成される。２つのビームの一方は、連接部近傍から延長方向に延びる延長部を有し、アクチュエータの開閉操作によって延長部が弾性変形することにより、ビームの開閉動作が行われる。
当該開閉動作は、筐体内において、最小限の動作範囲で行われることが好ましく、２つのビームの対向間隔を必要以上に大きくすることは、ビームの開閉動作の支点部に疲労を与える原因となりやすい。したがって、アクチュエータの開閉操作において、２つのビームの対向間隔が、アクチュエータの閉鎖位置で最も接近し、アクチュエータの開放位置で最も離隔する構造とすれば、最小限で動作範囲の設定が可能となる。
そのような構造を有するコネクタは特許文献１に開示されている。 In the prior art, many connectors including a housing and a contact portion that holds a flat cable are disclosed. The main structure is configured such that the contact portion has two opposing beams connected via a connecting portion. One of the two beams has an extending portion extending in the extending direction from the vicinity of the connecting portion, and the opening / closing operation of the beam is performed by elastically deforming the extending portion by the opening / closing operation of the actuator.
The opening / closing operation is preferably performed within a minimum operating range in the casing, and increasing the facing distance between the two beams more than necessary tends to cause fatigue at the fulcrum of the beam opening / closing operation. . Therefore, in the opening / closing operation of the actuator, the operation range can be set at a minimum by adopting a structure in which the facing distance between the two beams is closest in the closed position of the actuator and is most separated in the open position of the actuator.
A connector having such a structure is disclosed in Patent Document 1.

当該特許文献１では、コンタクト部が、２つのビーム及びそれを保持する基部ビームと一体形成されている。２つのビームの自由端は、無負荷状態の形状で平板状ケーブルの挿入時に平板状ケーブルと接するか、接する寸前となるように対向配置されている。基部ビームに支持されたビームの後端には、アクチュエータの操作部との係合部が設けられており、アクチュエータの回動操作の位置に応じて、アクチュエータの操作部がビーム後端の係合部と係合して後端部を押上げたり、押し下げたりしてビームに押圧力を加えるとともに、係合部と係合せずにコンタクト部を無負荷状態にする。
このような構造によって、アクチュエータの開放時には、ビームの自由端の対向間隔が拡がって平板状ケーブルの挿入が可能となり、アクチュエータの回動操作の中間位置では、コンタクト部が無負荷状態となるので、ビームの自由端の対向間隔が狭くなって平板状ケーブルと接触することとなり、アクチュエータの閉鎖時には、ビームの自由端の対向間隔がさらに狭くなって平板状ケーブルが把持される。 In Patent Document 1, the contact portion is integrally formed with two beams and a base beam that holds the beams. The free ends of the two beams are in an unloaded state and are disposed opposite each other so as to come into contact with or just before the flat cable when the flat cable is inserted. At the rear end of the beam supported by the base beam, an engaging portion with the actuator operating portion is provided, and the actuator operating portion engages with the rear end of the beam according to the position of the actuator rotating operation. The rear end is pushed up or down by engaging with the portion to apply a pressing force to the beam, and the contact portion is brought into an unloaded state without engaging with the engaging portion.
With such a structure, when the actuator is opened, the opposing distance between the free ends of the beam is widened so that a flat cable can be inserted, and the contact portion is in an unloaded state at an intermediate position of the rotation operation of the actuator. The facing distance between the free ends of the beam becomes narrow and comes into contact with the flat cable. When the actuator is closed, the facing distance between the free ends of the beam is further narrowed and the flat cable is gripped.

特開２００４−１５８２０６号JP 2004-158206 A

特許文献１は、ビーム自由端の対向間隔が最小限の範囲で変化する平板状ケーブルの把持構造を開示している。しかし、コンタクト部の形状及びアクチュエータの構造が複雑であるため、製造費用の面で多少不利な面がある。そこで、特許文献１と同様の把持能を有し、かつ、コンタクト部の構造を容易化した電気コネクタが市場で要望されている。   Patent Document 1 discloses a flat cable gripping structure in which the facing distance between the beam free ends changes within a minimum range. However, since the shape of the contact portion and the structure of the actuator are complicated, there are some disadvantages in terms of manufacturing costs. Therefore, there is a demand in the market for an electrical connector that has the same gripping ability as that of Patent Document 1 and that facilitates the structure of the contact portion.

本発明は、アクチュエータの回動操作による開閉動作において、アクチュエータの位置に応じて、コンタクト部を形成する２つのビームの間隔を最小限に変化させるコネクタであって、コンタクト部の構造が容易で新規的な電気コネクタを提供することを目的とする。   The present invention provides a connector for changing the interval between two beams forming a contact portion to a minimum in accordance with the position of the actuator in the opening / closing operation by the rotation operation of the actuator. It is an object to provide an electrical connector.

発明の効果
（１）本発明による電気コネクタは、アクチュエータを閉鎖する位置で、移動部が延長部と接触することによって、第１ビームが第２ビームに近接し、アクチュエータを開放する位置で、操作部が延長部と接触することによって、第１ビームが第２ビームから隔離されるので、コンタクト部が平板状ケーブルを把持するのに必要な変化範囲を最小限に設定し、コンタクト部の疲労を軽減することができる。
（２）本発明による電気コネクタのコンタクト部において、第１ビームが、アクチュエータの閉鎖位置における第１ビームの位置と、アクチュエータの開放位置における第１ビームの位置との中間位置で原形保持されるので、例えば、コンタクト部が弾性復元によって自然形状をなす位置で平板状ケーブルと接触するか、あるいは、接触寸前であれば、アクチュエータの回動操作中に、コンタクト部を静止させて平板状ケーブルを仮止めすることができる。
（３）本発明による電気コネクタは、回動軸部を収容する収容片が、延長部と第２ビームとの間の空間部に第２ビームを基端として延びているので、回動軸の軸受けとして機能を有する。
（４）本発明による電気コネクタにおいて、移動部と回動軸部との間を通って収容片が延びているので、アクチュエータの閉鎖時に移動部が第１ビームを押上げる力を加える際に、第１ビームからの応力を収容片が吸収し、第１ビームからの荷重による移動部の歪み等の変形を防止することができる。
（５）本発明による電気コネクタにおいて、第２ビームが筐体の一部と係止されているので、例えば、コンタクト部に外力が加わってもコンタクト部は所定の位置に固定され、本発明による電気コネクタは、所期の目的及び機能を発揮することができる。 Advantages of the Invention (1) The electrical connector according to the present invention is operated at a position where the first beam is close to the second beam and the actuator is opened when the moving portion comes into contact with the extension portion at a position where the actuator is closed. Since the first beam is isolated from the second beam by the contact of the extension portion with the extension portion, the change range necessary for the contact portion to grip the flat cable is set to a minimum, and the contact portion is less fatigued. Can be reduced.
(2) In the contact portion of the electrical connector according to the present invention, the first beam is held in its original form at an intermediate position between the position of the first beam in the closed position of the actuator and the position of the first beam in the opened position of the actuator. For example, if the contact portion comes into contact with the flat cable at a position where the natural shape is obtained by elastic restoration, or if the contact portion is about to come into contact, the contact portion is stopped during the rotation operation of the actuator and the flat cable is temporarily Can be stopped.

本発明の好ましい実施形態について実施例を挙げ、図面を参照して説明する。なお、各図において、同じ構成要素には同じ符号を用い、適宜その説明を省略する場合がある。   The preferred embodiments of the present invention will be described with reference to the accompanying drawings. In each drawing, the same reference numerals are used for the same components, and the description thereof may be omitted as appropriate.

図１は、本発明による電気コネクタ１の外観斜視図を示している。（ａ）は、平板状ケーブルを把持可能な態様を示し、（ｂ）は、平板状ケーブルを挿抜可能な態様を示している。電気コネクタ１は、一列に配列されたコンタクト部２と、該コンタクト部２を収容する筐体３とを備えている。
筐体３は、コンタクト部２を内部に収容するとともに、回動操作によって第１ビーム４（図２及び図３参照）を動作させるアクチュエータ１０を備えている。 FIG. 1 shows an external perspective view of an electrical connector 1 according to the present invention. (A) shows the aspect which can hold | grip a flat cable, (b) has shown the aspect which can insert / extract a flat cable. The electrical connector 1 includes a contact portion 2 arranged in a row and a housing 3 that accommodates the contact portion 2.
The housing 3 includes an actuator 10 that houses the contact portion 2 therein and operates the first beam 4 (see FIGS. 2 and 3) by a turning operation.

図２ないし図４は、いずれも電気コネクタ１のＡ−Ａ’の断面図であって、以下に共通する構成要素の形態を説明する。
コンタクト部２は、第１ビーム４と、第２ビーム５と、第１ビーム４から延びて第２ビーム５と連接された接続部８と、第１ビーム４及び接続部８から第１ビーム４の延長方向に延びる延長部６とで一体形成されており、平板状ケーブル（２点鎖線で示す）を第１ビーム４と第２ビーム５とによって把持する把持能を有する。
アクチュエータ１０は、アクチュエータを回動させるための操作部９と、回動操作によって回動する回動軸部１１と、回動操作によって前記延長部６と接触可能な移動部１２とを有して構成され、それらが一体的に形成されている。回動軸部１１及び移動部１２はコンタクト部２の配列方向に並列に延びた棒状の形体を有する。回動軸部１１は、筐体３の長手方向の端部における軸受け（図示せず）内にて回動自在に軸支されている。
延長部６と第２ビーム５との間の空間部には、回動軸部１１を収容するように、収容片７が延びており、該収容片７は、第２ビーム５を基端として回動軸部１１と移動部１２との間の隙間を通っている。回動軸部１１は、軸受け内で多少の空間（遊び）によって多少の移動が生ずる場合もあるが、常に収容片７の内部に収容されている。
第２ビーム５は、筐体３内の所定の挿入孔に挿入されて摩擦係止等によって固定される。これにより、移動部１２による延長部６への負荷、回動軸部１１と収容片７との摩擦、操作部９による延長部６への負荷、及び、平板状ケーブルとビームとの接触摩擦等に起因してぐらつきは生じない。 FIGS. 2 to 4 are cross-sectional views taken along the line AA ′ of the electrical connector 1, and the configuration of common components will be described below.
The contact portion 2 includes a first beam 4, a second beam 5, a connection portion 8 extending from the first beam 4 and connected to the second beam 5, and the first beam 4 and the connection portion 8 to the first beam 4. And an extension portion 6 that extends in the extending direction, and has a gripping ability to grip a flat cable (indicated by a two-dot chain line) with the first beam 4 and the second beam 5.
The actuator 10 includes an operation unit 9 for rotating the actuator, a rotation shaft unit 11 that rotates by the rotation operation, and a moving unit 12 that can contact the extension unit 6 by the rotation operation. They are constructed and formed integrally. The rotating shaft portion 11 and the moving portion 12 have rod-like shapes extending in parallel in the arrangement direction of the contact portions 2. The rotating shaft 11 is pivotally supported in a bearing (not shown) at the end in the longitudinal direction of the housing 3.
An accommodation piece 7 extends in the space between the extension 6 and the second beam 5 so as to accommodate the rotating shaft portion 11, and the accommodation piece 7 has the second beam 5 as a base end. It passes through a gap between the rotating shaft portion 11 and the moving portion 12. The rotating shaft portion 11 is always accommodated inside the accommodation piece 7 although there may be some movement due to some space (play) in the bearing.
The second beam 5 is inserted into a predetermined insertion hole in the housing 3 and fixed by friction locking or the like. Thereby, the load to the extension part 6 by the moving part 12, the friction between the rotating shaft part 11 and the receiving piece 7, the load to the extension part 6 by the operation part 9, the contact friction between the flat cable and the beam, etc. No wobble occurs due to

図２は、アクチュエータ１０を開放している態様を示している。
アクチュエータ１０の開放時には、回動軸１１は収容片７の内部に位置し、移動部１２は延長部６と非接触である。操作部９は延長部６と当接して第２ビーム５の方向に押圧力を加えている。それによって、第１ビーム４の自由端は、平板状ケーブルの厚みよりも広い間隔で第２ビームと離隔する方向に移動し、平板状ケーブルの挿入を許容している。次に、平板状ケーブルは、挿入口から挿入されて、第２ビームに沿って所定位置まで案内される。 FIG. 2 shows a mode in which the actuator 10 is opened.
When the actuator 10 is opened, the rotation shaft 11 is located inside the accommodation piece 7, and the moving part 12 is not in contact with the extension part 6. The operation portion 9 is in contact with the extension portion 6 and applies a pressing force in the direction of the second beam 5. As a result, the free end of the first beam 4 moves in a direction away from the second beam at intervals wider than the thickness of the flat cable, thereby allowing the flat cable to be inserted. Next, the flat cable is inserted from the insertion port and guided to a predetermined position along the second beam.

図３は、アクチュエータ１０が回動操作中の態様を示している。
図２の態様からアクチュエータ１０の回動軸１１を中心として回動操作を開始すると、延長部６が徐々に操作部９との当接から解放される。それにつれて、第１ビーム４が弾性的に復元し、第１ビーム４の自由端が第２ビーム５に接近する。そして、延長部６と操作部９との当接が完全に解放されると、第１ビーム４は、外力が加わらない無負荷状態となって、第２ビーム５との間隔が平板状ケーブルの厚みと略同一となる。これによって、平板状ケーブルは第１ビーム４と第２ビーム５の双方と当接して平板状ケーブルの厚み方向に仮止めされた状態となる。一方、移動部１２は、回動操作によって、延長部６の、第２ビーム５と対向する下方側に徐々に近接していき、回動操作を継続していくと徐々に延長部６の下方部に潜り込んで延長部６を第２ビーム５に対して垂直方向に押し上げる。 FIG. 3 shows a state in which the actuator 10 is being rotated.
When the rotation operation is started around the rotation shaft 11 of the actuator 10 from the mode of FIG. 2, the extension portion 6 is gradually released from contact with the operation portion 9. Accordingly, the first beam 4 is elastically restored, and the free end of the first beam 4 approaches the second beam 5. When the contact between the extension portion 6 and the operation portion 9 is completely released, the first beam 4 is in a no-load state where no external force is applied, and the distance between the second beam 5 and the flat cable is It is substantially the same as the thickness. As a result, the flat cable comes into contact with both the first beam 4 and the second beam 5 and is temporarily fixed in the thickness direction of the flat cable. On the other hand, the moving unit 12 gradually moves closer to the lower side of the extension 6 facing the second beam 5 by the turning operation, and gradually moves below the extension 6 as the turning operation is continued. The extension portion 6 is pushed up in the direction perpendicular to the second beam 5 by entering the portion.

図４は、図３の態様から回動操作をさらに継続し、最終位置でアクチュエータ１０を閉鎖している態様を示している。
アクチュエータ１０の閉鎖位置では、移動部１２は、収容片７と延長部６との間に位置し、収容片７で支持されるとともに、延長部６を第２ビーム５に対して鉛直上方に力を加えている。移動部１２は、延長部６を押し上げた力と反対方向の鉛直下方に応力を受けるが、その応力は、収容片７が移動部１２を押上げる力と相殺される。それによって、移動部１２では、延長部６の応力に起因する歪みが発生し難くなるとともに、最終的には、図４のように、延長部６が押上げられ、第１ビーム４の自由端が第２ビーム５の方向に近接する。その結果、第１ビーム４は、平板状ケーブルの一方の面上の接点を押圧し、第２ビーム５と協働して平板状ケーブルを把持する。 FIG. 4 shows a mode in which the rotation operation is further continued from the mode of FIG. 3 and the actuator 10 is closed at the final position.
In the closed position of the actuator 10, the moving part 12 is positioned between the accommodation piece 7 and the extension part 6, is supported by the accommodation piece 7, and forces the extension part 6 vertically upward with respect to the second beam 5. Is added. The moving part 12 receives a stress vertically downward in the direction opposite to the force pushing up the extension part 6, but the stress is offset by the force by which the receiving piece 7 pushes up the moving part 12. Thereby, in the moving part 12, distortion due to the stress of the extension part 6 hardly occurs, and finally, the extension part 6 is pushed up as shown in FIG. Is close to the direction of the second beam 5. As a result, the first beam 4 presses the contact on one surface of the flat cable, and grips the flat cable in cooperation with the second beam 5.

以上のように、アクチュエータ１０の回動操作の範囲を特定すると、第１ビーム４の第２ビーム５に対する開放位置及び閉塞位置が決定される。これによって、第１ビームの移動範囲を最小限に設定することができる。また、アクチュエータの回動操作中に、第１ビーム４が無負荷で移動範囲の中間位置で原形保持される形態を有するので、当該中間位置を基準にして第１ビーム４が開閉動作を行うこととなり、コンタクト部の変形範囲が従来よりも少なくなる。それによって、コンタクト部の疲労は軽減され、電気コネクタの寿命を延ばすことができる。
さらに、本発明は、コンタクト部２が２本のビーム４，５、それらの接続部８及び収容片７のみで構成されているので、従来の同様な機能を有する電気コネクタに比較して製造が容易となっているとともに、上述の目的を達成する新規的な電気コネクタの提供に寄与している。 As described above, when the range of the rotation operation of the actuator 10 is specified, the opening position and the closing position of the first beam 4 with respect to the second beam 5 are determined. Thereby, the moving range of the first beam can be set to a minimum. In addition, since the first beam 4 is held in its original form at an intermediate position in the moving range with no load during the rotation operation of the actuator, the first beam 4 performs an opening / closing operation with reference to the intermediate position. Thus, the deformation range of the contact portion is smaller than that in the conventional case. Thereby, fatigue of the contact portion is reduced, and the life of the electrical connector can be extended.
Furthermore, since the contact portion 2 is composed of only the two beams 4 and 5, their connecting portion 8 and the receiving piece 7, the present invention can be manufactured in comparison with a conventional electrical connector having the same function. It is easy and contributes to the provision of a novel electrical connector that achieves the above-mentioned object.
