Description

【０００１】
【発明の属する技術分野】
本発明は、シーソー式の可動接点により切り換えを行うスイッチ装置に関し、特に自動車などのパワーシートスイッチやパワーウィンドウスイッチ等に使用されるスイッチ装置に関する。
【０００２】
【従来の技術】
自動車などに搭載されて使用される操作スイッチとしては、プッシュスイッチやロータリースイッチを始めとして各種の電気的スイッチが使用されている。この中でもパワーシートスイッチやパワーウィンドウスイッチにはスライドスイッチやシーソースイッチ等が主に使用されている。
【０００３】
従来のこれらに使用されるスイッチ装置としては図６及び図７に示すものがある。図６は従来のスライドスイッチの製品斜視図、図７は同じく分解斜視図である。
【０００４】
図において、ハウジング１１は、合成樹脂等の絶縁材で有底状の箱型に形成されており、このハウジング１１の有底部には、黄銅等の導電性の金属板からなる固定端子１２が配設されている。この固定端子１２上には、同じく導電性の金属板からなる略Ｍ字状の可動接点１３が載置されており、前記固定端子１２に設けられた固定接点（図示せず）と、この可動接点１３に設けられた接点部１３ａが離接することによりスイッチの切り換えが行われるようになっている。
【０００５】
また、前記可動接点１３の上側には、駆動部材１４が配設されており、この駆動部材１４が前記可動接点１３の上面を摺動して移動することにより、前記可動接点１３が揺動され、前記接点部１３ａが前記固定接点と離接するようになっている。また、前記駆動部材１４には付勢用のコイルばね１５が配設されており、このコイルばね１５により前記駆動部材１４を前記可動接点１３方向へ弾圧している。
【０００６】
スライド部材１６は、合成樹脂等の絶縁材で形成され、このスライド部材１６の上面には操作用のツマミ１６ａが形成され、対向する両側面にはクリック用のカム１６ｂが設けられている。また、このスライド部材１６の底面側には、前記駆動部材１４を挿入して位置決めする挿入孔（図示せず）が設けられており、前記スライド部材１６のスライド方向への移動に伴って前記駆動部材１４も移動されるものとなっている。
【０００７】
カバー１７は、同じく合成樹脂などの絶縁材で形成され、前記ハウジング１１の開口部を覆うように取り付けられ、前記ハウジング１１及び前記カバー１７との間に、前記可動接点１３、駆動部材１４、コイルばね１５、スライド部材１６が配設されるものとなっている。また、前記カバー１７の上面中央には、前記スライド部材１６の操作用のツマミ１６ａが貫通する窓孔１７ａが形成されている。この窓孔１７ａを介して前記スライド部材１６の操作用のツマミ１６ａを操作することができる様になっている。
【０００８】
【発明が解決しようとする課題】
しかしながら、上述した従来のスライドスイッチの構造においては、カバーとスライド部材と駆動部材とは各々別部品から形成されており、また、カバーとスライド部材と駆動部材とは一体化できる構成にはなっていないことから、部品点数が増加し、組立作業性が悪いという問題があった。
【０００９】
また、駆動部材の付勢部材としてコイルばねを使用しており、コイルばねの必要荷重を得るためには巻線方向に一定寸法を必要とすることから、縦方向の長さが長くなってしまい、スイッチの薄型化を図ることが難しいという問題があった。
【００１０】
したがって、本発明では上述した問題点を解決し、スライドスイッチの構造で、カバーとスライド部材を一体化して部品点数を削減し、付勢部材として板ばねを使用してスライド部材に板ばねを駆動部材でスナップ止めすることで、組立作業性を向上させると共に、スイッチの薄型化を図ることが可能なスライドスイッチの構造を提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記課題を解決するために本発明では、第１の手段として、収納部を有し、この収納部の有底部に固定接点が配設されたハウジングと、前記収納部に収納され、前記固定接点と離接する可動接点と、この可動接点を動作させる駆動部材と、前記駆動部材と係合し、前記駆動部材をスライド移動させるスライド部材とを備え、前記スライド部材及び前記駆動部材は合成樹脂の絶縁材からなる成形品で形成され、前記スライド部材は、前記収納部を覆うカバー部が一体的に形成されると共に、前記スライド部材と前記駆動部材との間には、薄板状からなる板ばねが介在され、この板ばねによって前記駆動部材が前記可動接点方向へ弾圧された状態で、前記スライド部材に、前記駆動部材をスナップ止めで取り付け、前記スライド部材が前記ハウジングに一体化される前の状態において前記板ばねが前記スライド部材と前記駆動部材との間で、前記駆動部材の前記スライドへのスナップ止めによって取り付けられていることを特徴とする。
【００１２】
また、第２の手段として、前記駆動部材を、前記スライド部材に着脱可能に取り付けたことを特徴とする。
【００１３】
また、第３の手段として、前記駆動部材を、一対並べて取り付けたことを特徴とする。
【００１７】
【発明の実施の形態】
以下、本発明のスライドスイッチの構造の１実施例を図１乃至図５に示す。図１はスライドスイッチの製品斜視図、図２は同じく分解斜視図、図３は同じく縦断面図、図４はスライド部材に板ばねと駆動部材を取り付けた状態の説明図、図５は図４の５−５線における断面図である。
【００１８】
図において、ハウジング１は、合成樹脂などの絶縁材からなり、上面が開口された有底状の箱形に形成されている。このハウジング１の有底部には、導電性の金属材からなる固定端子２が配設されており、この固定端子２の一端側は前記ハウジング１の外方へ導出されて、図示しない回路基板の回路パターンと接続される接続端子２ａが形成されている。また、前記固定端子２の他端側は前記ハウジング１の内底面に表出されており、中央の前記固定端子２を挟んで対向する両側の前記固定端子２の上面側には、突出した固定接点２ｂが各々形成されたものとなっている。また、中央の前記固定端子２の他端側はＬ字状に折り曲げられて固定接点２ｃを形成している。
【００１９】
前記ハウジング１の開口内部には、一対の収納部１ａが形成されており、この収納部１ａに後述する可動接点３が収納されるものとなっている。この収納部１ａの両側壁には一対のガイド突起１ｂが各々設けられており、このガイド突起１ｂに後述する可動接点３のガイド凹部３ａが係合されて、この可動接点３が前記固定端子２上を揺動可能に配設されている。
また、前記ハウジング１の外側面部には、一対の係止突部１ｃが形成されており、この係止突部１ｃと後述するスライド部材６に設けられた係止窓部６ｃが係合されるものとなっている。
【００２０】
可動接点３は、導電性の金属材で略Ｍ字状の板状に形成されている。この可動接点３の中央部のＶ字状部分には、前記ハウジング１の収納部１ａに設けられた前記ガイド突起１ｂに係合されるガイド凹部３ａが設けられ、前記ガイド突部１ｂを支点部として前記可動接点３が前記固定端子２上を揺動するようになっている。
また、前記可動接点３の両端側の自由端部が、前記固定接点２ｂと離接する接点部３ｂとなっている。
【００２１】
駆動部材４は、合成樹脂などの絶縁材で形成されており、この駆動部材４には方形状からなる基部４ａと、この基部４ａの一端側に突出して形成された摺動部４ｂが設けられている。この摺動部４ｂの先端側は円弧面状に形成され、前記可動接点３の上面側の摺動面３ｃと摺動する場合に摺動しやすくなっている。
また、前記基部４ａの他端側には後述する板ばね５と係合する係合突起４ｃが設けられ、この係合突起４ｃが板ばね５に設けられた係合凹部５ａと係合されるようになっている。
【００２２】
板ばね５は、ばね用リン青銅等のばね性を有する金属材で板状に形成されており、なだらかな略Ｖ字状とされ、その中央部には前記駆動部材４の係合突起４ｃが係合される係合凹部５ａが設けられている。前記板ばね５が後述するスライド部材６に組み込まれた場合、この係合凹部５ａが設けられた部分に隆起部５ｂが形成されるものとなり、この隆起部５ｂの撓みによって前記駆動部材４に弾性を付与するものとなっている。
【００２３】
スライド部材６は、合成樹脂などの絶縁材からなり、下面が開口された箱形に形成されている。このスライド部材６は、前述した従来例で説明したカバー１７を兼用しており、前記ハウジング１の開口部を覆うカバーの役目も兼ね備えたものとなっている。即ち、このスライド部材６には、カバー部６ａが形成されており、このカバー部６ａの上面には、操作用のツマミ部６ｂが設けられている。この操作用のツマミ部６ｂに図示しない操作機器の化粧ツマミが嵌合されて人間の指などによって操作されるものとなっている。
また、前記スライド部材６の両側面部には、前記ハウジング１に設けられた一対の係止突部１ｃに係合し、抜け止めされると共に、前記ハウジング１の開口部上を横方向に移動可能となるように横長の係止窓部６ｃが前記係止突部１ｃに対向して一対設けられている。
【００２４】
前記スライド部材６の開口内部には、前記板ばね５を保持する一対の板ばね保持部６ｄが設けられており、この板ばね保持部６ｄの中央部には、更に前記駆動部材４を保持する一対の駆動部材保持部６ｅが設けられている。この駆動部材保持部６ｅにはフック部６ｆが形成されており、このフック部６ｆが前記駆動部材４の前記基部４ａに弾接するようになっている。
この場合、前記板ばね保持部６ｄに前記板ばね５を挿入して、次に、前記板ばね５の係合凹部５ａに前記駆動部材４の係合突起４ｃを係合して前記駆動部材４を前記駆動部材保持部６ｅに挿入することにより、前記フック部６ｆにより前記駆動部材４が前記駆動部材保持部６ｅ内にスナップ止めで取付られるものとなっている。
【００２５】
次に、上記の実施例で説明したスライドスイッチの組立方法、及び動作を説明する。
まず、前記ハウジング１の収納部１ａに前記可動接点３を挿入する。この場合、本実施例では前記可動接点３は２個（２回路）挿入するが、用途によっては１個（１回路）でもよい。
【００２６】
次に、前記スライド部材６の開口内部の前記板ばね保持部６ｄに前記板ばね５を挿入する。そしてこの板ばね５の中央に設けられた前記係合凹部５ａに前記駆動部材４の係合突起４ｃを係合し、前記駆動部材４を前記スライド部材６の開口内部の前記駆動部材保持部６ｅに挿入する。この時、前記板ばね５は前記駆動部材４により前記スライド部材６にスナップ止めで取り付けられるものとなり、三位一体となる。尚、前記駆動部材４は前記スライド部材６に着脱可能となっているため、用途や仕様に応じて１個（１回路）又は２個（２回路）を取り付けるように選択することが可能となっている。
【００２７】
この状態で、前記スライド部材６を前記ハウジング１の収納部１ａを覆う様に被せ、前記係止窓部６ｃと前記係止突部１ｃとを嵌合させることで一体化し、組立が完了する。この時、前記駆動部材４は、前記板ばね５の弾圧により上下方向、即ち、前記可動接点３の方向へ付勢されていることから、前記可動接点３は前記駆動部材４によって前記固定端子２側へ押圧されて、前記固定接点２ｃと常接し、また、前記接点部３ｂは前記固定接点２ｂと接触することとなる。
【００２８】
この状態から、前記スライド部材６の操作用のツマミ部６ｂを操作させると、前記スライド部材６に取り付けられた前記駆動部材４が、前記可動接点３の前記摺動面３ｃ上をスライド方向に摺動し、前記可動接点３が揺動することにより前記接点部３ｂと前記固定接点２ｂとが離接することでスイッチの切り換えが行われるものとなる。この時、前記駆動部材４は、前記駆動部材保持部６ｅ内で前記板ばね５により弾圧された状態で、上下方向に移動可能に保持されたものとなっている。
【００２９】
上記の本発明の実施例によれば、前記スライド部材６と従来例のカバー１７とを一体的に形成し、一つの部品で兼用したことから、部品点数の削減が図れ、また、前記駆動部材４と前記板ばね５を前記スライド部材６にスナップ止めで取り付け三位一体構造としたことから、組立途中で前記板ばね５や前記駆動部材４が落下する虞がなくなり、組立作業性が著しく向上されるものとなっている。
【００３０】
また、前記駆動部材４を付勢するばね部材を薄い板状の前記板ばね５で形成したことから、前記ハウジング１や前記スライド部材６の縦方向の長さを短くすることができ、スイッチの薄型化を図ることが可能となっている。
【００３１】
また、前記駆動部材４と前記板ばね５を一体化して、前記板ばね５に駆動部を形成することも考えられるが、この場合には、前記可動接点３が導電性の金属材から形成されていることから、金属同士の摺動となり、摺動面が焼き付けを起こすことから、接点の信頼性や動作フィーリングなどを考慮すると好ましくない。この点、本実施例では、前記駆動部材４が合成樹脂製の成形材で形成されていることから、その滑り性も良好で接点の信頼性や動作フィーリングなども良好な結果が得られるものとなる。
【００３２】
また、前記駆動部材４を別部品として一対（２個）設けたことから、前記スライド部材６の前記駆動部材保持部６ｅの形成位置を互いに変更することにより、スイッチの回路構成を、例えば、１回路はノーマルオープンで、他の１回路はノーマルクローズなどに変更することが可能となる。
【００３３】
尚、上記実施例では、前記駆動部材４を前記スライド部材６に形成した前記フック部６ｆにスナップ止めして取り付けるように構成したが、これとは別に、前記フック部６ｆを前記駆動部材４側に形成しても良く、この場合でも上述したのと同様な効果が得られるのはもちろんである。
【００３４】
【発明の効果】
以上説明したように、本発明のスライドスイッチの構造は、収納部を有し、この収納部の有底部に固定接点が配設されたハウジングと、収納部に収納され、固定接点と離接する可動接点と、この可動接点を動作させる駆動部材と、駆動部材と係合し、駆動部材をスライド移動させるスライド部材とを備え、スライド部材には、収納部を覆うカバー部が一体的に形成されており、スライド部材に、駆動部材をスナップ止めで取り付けたことから、部品点数の削減が図れ、また、組立途中で前記駆動部材が落下する虞がなくなり、組立作業性が著しく向上されるものとなる。
【００３５】
また、駆動部材が、合成樹脂からなる成形品で形成されたことから。可動接点との滑り性も良好で、接点の信頼性や動作フィーリングなども良好な結果が得られる。
【００３６】
また、駆動部材を、スライド部材に着脱可能に取り付けたことから、用途や仕様に応じて１個（１回路）、又は２個（２回路）を取り付けるように選択することが可能となり各種バラエティーに対応できる。
【００３７】
また、駆動部材を、一対並べて取り付けたことから、スライド部材の駆動部材保持部の形成位置を互いに変更することにより、スイッチの回路構成を簡単に変更することが可能となる。
【００３８】
また、スライド部材と駆動部材との間には、薄板状からなる板ばねが介在されており、この板ばねによって駆動部材を可動接点方向へ弾圧したことから、ハウジングやスライド部材の縦方向の長さを短くすることができ、スイッチの薄型化を図ることが可能となる。
【００３９】
また、板ばねが、スライド部材と駆動部材との間で、駆動部材のスライド部材へのスナップ止めによって取り付けられたことから、三位一体構造となり、組立途中で板ばねや駆動部材が落下する虞がなくなり、組立作業性が著しく向上されるものとなる。

In this state, the slide member 6 is covered so as to cover the housing portion 1a of the housing 1, and the locking window portion 6c and the locking projection 1c are fitted together to complete the assembly. At this time, the driving member 4 is biased in the vertical direction by the elastic force of the leaf spring 5, that is, in the direction of the movable contact 3, so that the movable contact 3 is moved by the driving member 4 to the fixed terminal 2. The contact portion 3b is pressed to the side and is always in contact with the fixed contact 2c, and the contact portion 3b is in contact with the fixed contact 2b.
[0028]
From this state, when the operating knob 6b of the slide member 6 is operated, the drive member 4 attached to the slide member 6 slides on the sliding surface 3c of the movable contact 3 in the sliding direction. When the movable contact 3 swings and the movable contact 3 swings, the contact portion 3b and the fixed contact 2b are separated from each other, whereby the switch is switched. At this time, the driving member 4 is held so as to be movable in the vertical direction while being pressed by the leaf spring 5 in the driving member holding portion 6e.
[0029]
According to the above-described embodiment of the present invention, the slide member 6 and the conventional cover 17 are integrally formed and used as a single component, so that the number of components can be reduced, and the drive member can be reduced. 4 and the plate spring 5 are attached to the slide member 6 by snapping to form a three-piece integrated structure, so that the plate spring 5 and the drive member 4 are not likely to fall during assembly, and the assembly workability is remarkably improved. It has become a thing.
[0030]
Further, since the spring member for biasing the drive member 4 is formed by the thin plate-like plate spring 5, the longitudinal length of the housing 1 and the slide member 6 can be shortened, and the switch It is possible to reduce the thickness.
[0031]
In addition, it is conceivable that the driving member 4 and the leaf spring 5 are integrated to form a driving portion in the leaf spring 5. In this case, the movable contact 3 is formed of a conductive metal material. Therefore, it is not preferable in view of contact reliability, operational feeling, and the like because the metal slides and the sliding surface seizes. In this respect, in this embodiment, since the drive member 4 is formed of a molding material made of a synthetic resin, the sliding property is good, and the contact reliability and operation feeling are good. It becomes.
[0032]
In addition, since a pair (two) of the drive members 4 are provided as separate parts, the circuit configuration of the switch can be changed to, for example, 1 by changing the formation position of the drive member holding portion 6e of the slide member 6 to each other. The circuit is normally open, and the other circuit can be changed to normally closed.
[0033]
In the above embodiment, the drive member 4 is snapped onto the hook portion 6f formed on the slide member 6. However, separately from this, the hook portion 6f is attached to the drive member 4 side. Of course, in this case, the same effect as described above can be obtained.
[0034]
【The invention's effect】
As described above, the structure of the slide switch according to the present invention has a housing portion, a housing in which a fixed contact is disposed on the bottomed portion of the housing portion, and a movable member that is housed in the housing portion and separates from and comes into contact with the fixed contact. A contact member, a drive member that operates the movable contact member, and a slide member that engages with the drive member and slides the drive member. A cover portion that covers the storage portion is integrally formed on the slide member. In addition, since the drive member is attached to the slide member by snapping, the number of parts can be reduced, and there is no possibility of the drive member falling during the assembly, so that the assembly workability is remarkably improved. .
[0035]
In addition, the drive member is formed of a molded product made of synthetic resin. The sliding property with the movable contact is also good, and good results such as contact reliability and operation feeling can be obtained.
[0036]
In addition, since the drive member is detachably attached to the slide member, it can be selected to attach one (one circuit) or two (two circuits) according to the application and specifications. Yes.
[0037]
In addition, since the drive members are mounted side by side, the circuit configuration of the switch can be easily changed by changing the formation positions of the drive member holding portions of the slide members.
[0038]
In addition, a thin plate-like plate spring is interposed between the slide member and the drive member, and the drive member is elastically pressed toward the movable contact point by the plate spring, so that the longitudinal length of the housing and the slide member is increased. Therefore, the switch can be made thinner.
[0039]
In addition, since the leaf spring is attached between the slide member and the drive member by snapping the drive member to the slide member, a three-way structure is formed, and there is no possibility that the leaf spring or the drive member falls during assembly. As a result, the assembly workability is remarkably improved.
