【０００１】
【発明の属する技術分野】
本発明は、携帯電話、ＰＨＳ等の携帯用電子機器等に使用され、操作体が回動することで接点の切換が行われる回動操作型電気部品に関する。
【０００２】
【従来の技術】
従来の回動操作型電気部品の図面を説明すると、図１３は従来の回動操作型電気部品の要部断面図、図１４は従来の回動操作型電気部品の分解斜視図、図１５、図１６は従来の回動操作型電気部品の操作を説明するための説明図である。
【０００３】
従来の回動操作型電気部品を図１３〜図１６に基づいて説明すると、ケーシング５０は、合成樹脂の成型品からなり、矩形状の基部５０ａと、該基部５０ａの上面に形成され、開口部が正方形をなす第１の凹部５０ｂと、該第１の凹部５０ｂの近傍に形成され、開口部が長方形をなす第２の凹部５０ｃと、この第２の凹部５０ｃに並設された第３の凹部５０ｄとを有し、第２の凹部５０ｃ内には略Ｕ字状の受け部５０ｅが設けられている。また、短手側の両壁部の近傍には通孔５０ｆが一対設けられており、この通孔５０ｆは該壁部に形成された係合孔５０ｇに連通している。
【０００４】
第１の凹部５０ｂ内には、プッシュスイッチ用の第１の固定接点５１が埋設され、第３の凹部５０ｄ内には中央に帯状の第２の固定接点５２ａが埋設されると共に、この第２の固定接点５２ａの両側近傍には底壁面が露出した露出部５０ｈを介して第３の固定接点５２ｃが一対埋設されている。
【０００５】
ドームバネ５３は、反転復帰可能な金属板からなり、第１の固定接点５１上に載置され、このドームバネ５３と第１の固定接点５１とでプッシュスイッチＰ１が構成されている。シート５４は絶縁性の可撓性を有するフィルムからなり、第１の凹部５０ｂを覆うように固定されている。
【０００６】
可動体５５は、合成樹脂の成型品からなる本体部５５ａと、該本体部５５ａに取り付けられている金属からなる摺動子５５ｂとから構成され、本体部５５ａは、平板の矩形状をなす取付部５５ｃと、該取付部５５ｃの上面からＵ字状に突出して形成された係合部５５ｄとを有する。また、摺動子５５ｂは、平板状の基部５５ｅと、該基部５５ｅの両端から下方に屈曲して延びる一対の摺動子片５５ｆとを有し、基部５５ｅがカシメ等の方法で取付部５５ｃに固定されて、摺動子５５ｂが本体部５５ａに固定される。
【０００７】
このような可動体５５は、第３の凹部５０ｄ内にスライド移動可能に収納され、摺動子片５５ｆが露出部５０ｈに位置するときに中立状態にあり、この可動体５５がスライド移動すると、摺動子片５５ｆが第２、第３固定接点５２ａ、５２ｃ上を摺動して、第２、第３固定接点５２ａ、５２ｃ間がＯＮするようになっている。そして、可動体５５と、第２、第３固定接点５２ａ、５２ｃとでスライドスイッチＳ１を構成している。
【０００８】
カバー５６は、金属板をプレス加工した後に、折り曲げ加工したものから構成され、平板状の板状部５６ａと、該板状部５６ａに形成された矩形状の第１の通孔５６ｂと、該板状部５６ａの中間部の短手方向に形成された第２の通孔５６ｃと、該第２の通孔５６ｃの近傍に形成された第３の通孔５６ｄ、板状部５６ａの短手側の両側縁を凹状に切り欠かれて形成された一対の切込部５６ｅとを有する。また、第２の通孔５６ｃの両端部には斜向かいの位置に、上方にＬ字状に延びる第１の係止部５６ｆと、第２の係止部５６ｇが一対形成されており、第３の通孔５６ｄの長手側の内縁部には、上方に突出する一対のガイド壁５６ｈが形成されている。
【０００９】
このようなカバー５６は、ケーシング５０を上方から覆うように固定され、このカバー５６がケーシング５０に固定されると、第２の通孔５６ｃから受け部５０ｅが突出すると共に、第３の凹部５０ｄから可動体５５の係合部５５ｄが突出した状態になる。また、ケーシング５０の通孔５０ｆは切込部５６ｅがあるため、上方に開放したままの状態となっている。
【００１０】
ねじりバネ５７は、巻回部５７ａと、巻回部５７ａの両端から離れる方向に延びる一対の第１、第２のアーム部５７ｂ、５７ｃとを有する。このねじりバネ５７は、巻回部５７ａが受け部５０ｅはめ合わされ、第１のアーム部５７ｂが第１の係止部５６ｆに掛け止められ、第２のアーム部５７ｃが第２の係止部５６ｇに掛け止められた状態で保持される。
【００１１】
操作体５８は、合成樹脂の成型品からなり、矩形板が湾曲した形状を有する基体５８ａと、この基体５８ａの両端部に形成された一対の扇状の側壁部５８ｂとを有し、基体５８ａは、上面側の頂部に長手方向に間隔を置いて形成されたレール状の２本の凸条部５８ｈと、下面側に下方に突出するように形成された押圧部５８ｃと、下面側の略中間部から一対広がるようハ字状に形成された第１の突起５８ｄ、及び第２の突起５８ｅと、下方に突出すると共に先端が丸みを帯びた係合突起５８ｇとを有する。また、側壁部５８ｂは、互いに離れるように突出するＬ字状の係合爪５８ｆを有する。
【００１２】
このような構成をした操作体５８は、係合爪５８ｆがケーシング５０の通孔５０ｆ内に挿入され、係合孔５０ｇに係合することで、ケーシング５０に対して回動可能な状態で保持されると共に、係合爪５８ｇが係合孔５０ｇ内を上下方向に移動可能となっているので、操作体５８は上下方向にも移動可能となっている。また、押圧部５８ｃは、第１の通孔５６ｂを貫通してシート５４に当接する状態となり、第１、第２の突起５８ｄ、５８ｅは、第１、第２の係止部５６ｆ、５６ｇに掛け止めされた第１、第２のアーム部５７ｂ、５７ｃに当接した状態となる。さらに、係合突起５８ｇが可動体５５の係合部５５ｄに係合した状態となっている。
【００１３】
このように回動可能に保持された操作体５８が回動されると、図１５、図１６を参照するに、回動方向と同方向側に可動体５５が係合突起５８ｇに追従して、スライド移動し、第２、第３の固定接点５２ａ、５２ｃ上に摺動子５５ｂの摺動子片５５ｆが摺接し、該第２、第３の固定接点５２ａ、５２ｃ間がＯＮとなり、スライドスイッチＳ１が操作されるようになっている。また、回動側の突起５８ｄ、５８ｅが（図面では第１の突起５８ｄ）、回動側のアーム部５７ｂ、５７ｃ（図面では第１のアーム部５７ｂ）を押圧して、ねじりバネ５７が撓むようになっている。次に、操作力が解除されると、撓んだアーム部５７ｂ、５７ｃが係止部５６ｆ、５６ｇに当接するまで復帰し、この復帰力で突起５８ｄ、５８ｅが押圧されて操作体５８が中立位置に復帰し、この操作体５８の復帰に追従して可動体５５が中立位置に復帰し、第２、第３の固定接点５２ｂ、５２ｃ間がＯＦＦとなるようになっている。
【００１４】
従来の回動操作型電気部品は上記のような構成をなし、次にその動作について図１５、図１６に基づいて説明すると、図１５のように操作体５８が図中左方向に回動されると、これに追従して可動体５５がスライド移動して、ＯＮ信号が出力され、また、操作力が解除されると、第１のアーム部５７ｂの復帰力により、操作体５８が図１３に示す中立位置に復帰し、可動体５５が中立位置に復帰して、再びＯＦＦ状態となる。また、凸条部５８ｈの一端部近傍が押圧されると、プッシュスイッチＰ１が操作される。
【００１５】
【発明が解決しようとする課題】
従来の回動操作型電気部品は上記のような構成、動作をするが、操作体５８に追従して可動体５５が移動し、操作体５８をねじりバネ５７によって復帰させる構成をとっているため、係合突起５８ｇと係合部５５ｄ間にガタが生ずると、操作体５８は中立位置に復帰しても、可動体５５が中立位置に復帰せず、スライドスイッチＳ１がＯＦＦ状態に確実にならないという問題がある。更に、ねじりバネ５７の第１、第２のアーム部５７ｂ、５７ｃが第１、第２の係止部５６ｆ、５６ｇに掛け止めされており、操作体５８が中立位置に置いてフリーの状態になっており、操作体５８にガタが生じやすいという問題もある。更には、図１６に示すように、操作体５８の回動時、第１、第２の突起５８ｄ、５８ｅが第１、第２のアーム部５７ｂ、５７ｃと擦れ合うため、操作が繰り返されると、第１、第２の突起５８ｄ、５８ｅの特定部分が削れて、変形してしまい、操作体５８の中立位置への復帰が確実に行われないと共に、回動操作型電気部品自体の寿命も短くなるという問題がある。さらに、プッシュスイッチＰ１が中心からずれた位置に配置せざるを得ず、凸条部５８ｈの他端部近傍を押圧した場合、プッシュスイッチＰ１が操作されず、操作感が悪化するという問題がある。
【００１６】
本発明はかかる課題に鑑みてなされたものであり、バネによって可動体を直接中立位置に復帰させることで、復帰時に確実に接点切換が行われ、更には長寿命の回動操作型電気部品を提供することを目的とする。
【0017】
【課題を解決するための手段】
上記課題を解決するための第１の手段として、本発明の回動操作型電気部品は、導電パターン若しくは該導電パターンに摺動して接点切換を行う摺動子の一方を有するケーシングと、前記導電パターン若しくは前記摺動子の他方を有し、前記ケーシング内にスライド移動可能に収納された可動体と、前記ケーシングに回動可能に保持され、前記可動体をスライド移動させると共に、前記接点の切換を行う操作体と、前記ケーシングと前記可動体の間に、前記可動体の前記移動方向に沿って配置されると共に、前記操作体の回動操作時に縮み、操作力が解除されることで弾性によって前記可動体が復帰するように伸縮可能なコイルバネとを備え、前記ケーシングはプッシュスイッチを有し、前記可動体は、貫通孔を有すると共に、前記ケーシングと前記操作体との間に配置され、前記貫通孔内には押圧部材が上下動可能に収納されており、前記操作体は前記ケーシング及び前記可動体に対して上下動可能に保持され、前記ケーシングと前記操作体の間には、付勢部材と該付勢部材が押し付けられる前記押圧部材が配設され、前記付勢部材は前記操作体と共に回動可能となるように保持され、前記付勢部材はねじりバネをなし、前記ねじりバネは、巻回部と、巻回部の両端から可動体の移動方向に延びる一対のアーム部とを有し、この一対のアーム部が操作体の下面に当接した状態で操作体を付勢していると共に、前記コイルバネが前記ねじりバネを挟んで両側に一対に並設されており、前記操作体が押圧されることで、前記付勢部材が前記押圧部材を押圧して前記プッシュスイッチが操作されることを特徴とする構成とした。
【００１８】
また、第２の解決手段として、本発明の回動操作型電気部品の前記ケーシングと前記操作体の間には、前記操作体は、前記押圧部材に押し付けられた前記付勢部材によって付勢された状態で前記ケーシングに回動可能に保持されている構成とした。
【００２２】
また、第3の解決手段として、本発明の回動操作型電気部品の前記押圧部材は、前記プッシュスイッチによって前記付勢部材に押し付けられるように付勢され、前記押圧部材によって前記付勢部材を介して前記操作体が押圧されている構成とした。
【００２４】
また、第4の解決手段として、本発明の回動操作型電気部品の前記プッシュスイッチは前記ケーシングの中央部に配置されると共に、前記貫通孔は前記可動体の中央部に配置されて、該可動体が中立位置にあるとき前記貫通孔と前記プッシュスイッチは一直線上に位置し、前記操作体を前記可動体に対して上下動可能にガイドする保持部が前記貫通孔を挟んだ両側に設けられている構成とした。
【００２５】
【発明の実施の形態】
本発明の回動操作型電気部品の図面を説明すると、図１は本発明の回動操作型電気部品の要部断面図、図２は図１の２−２線における断面図、図３は図１の３−３線における断面図、図４は本発明の回動操作型電気部品の分解斜視図、図５は本発明の回動操作型電気部品のケーシングの上面図、図６は図５の６−６線における断面図、図７は本発明の回動操作型電気部品の操作体の上面図、図８は図７の８−８線における断面図、図９は本発明の回動操作型電気部品の可動体の下面図、図１０は図９の１０−１０線における断面図、図１１、図１２は本発明の回動操作型電気部品の操作を説明するための説明図である。
【００２６】
本発明の回動操作型電気部品を図１〜図１２に基づいて説明すると、ケーシング１は、合成樹脂の成型品からなり、平板状で箱形を呈する基部１ａと、該基部１ａの中央部に形成されている円状の凹部１ｂと、該凹部１ｂの両側近傍に形成され、短手方向に延びる一対の第１の溝部１ｃと、該第１の溝部１ｃの外側に形成され、短手方向に延びる一対の第２の溝部１ｄと、該第２の溝部１ｄの両壁部に設けられた凹部で、断面半円状を呈する収納部１ｅとを有し、この収納部１ｅは凹部１ｂの径と同等の長さをなしている。また、基部１ａを形成する短手方向に延びる一対の壁部１ｆの中間には、逆Ｕ字状の突起である係合凹部１ｇが形成されている。
【００２７】
プッシュスイッチ用の固定接点２は、中央接点２ａと、弓状の周辺接点２ｂとを有し、これらの固定接点２は凹部１ｂ内に埋設され、中央接点２ａの先端が露出すると共に、周辺接点２ｂが中央接点２ａを囲むように露出した状態となっている。
【００２８】
第１の固定接点３ａは帯状を呈する金属板からなり、第１の溝部１ｃ内で露出すると共に、端子が埋設されて外部に突出した状態になっている。また、第２の固定接点３ｂは、第１の固定接点３ａと同幅を有する短い金属板からなり、第１の溝部１ｃの端部近傍に露出すると共に、端子が埋設されて外部に突出した状態となっている。また、この第１、第２の固定接点３ａ、３ｂの間には基部１ａの内底面が露出して露出部１ｋを形成している。このような構成をなした第１、第２の固定接点３ａ、３ｂが固定接点２の両側に配置されている。
【００２９】
ドームバネ４は、ドーム状の金属からなり、反転可能となっており、凹部１ｂ内に載置されて収納されている。そして、このドームバネ４と固定接点２とでプッシュスイッチＰが構成されている。シート５は、絶縁性の可撓性を有するフィルムからなり、ドームバネ４をケーシング１に保持するためのものであり、凹部１ｂを覆うようにケーシング１に貼り付けられて固定されている。
【００３０】
コイルバネ６は金属製のバネであり、それぞれの第２の溝部１ｄの両側壁に形成された収納部１ｅ内に収納され、両方の端部６ａのそれぞれが収納部１ｅの端部に形成された止め部１ｈに弾接した状態になっており、外部からの荷重によって伸縮可能となっている。このコイルバネ６は、一旦縮められてから収納部１ｅ内に組み込まれるものである。
【００３１】
可動体１０は、図９、図１０に示すように、合成樹脂の成型品からなる本体部１０ａと、該本体部１０ａに取り付けられている一枚の金属板からなる摺動子１０ｂとから構成され、本体部１０ａは、平板状の基部１０ｃと、該基部１０ｃの中央に形成された貫通孔１０ｄと、該貫通孔１０ｄを挟んだ両側に一対形成され、上方に突出して形成された略Ｕ字状の保持部１０ｅと、下面の両端にそれぞれ形成され、短手方向に延びると共に、外部に開放するように形成された凹部１０ｆと、この凹部１０ｆの端部に隣接して配置され、下方に突出して４角に形成された突起１０ｇとを有する。
【００３２】
摺動子１０ｂは、平板状の取付部１０ｈと、該取付部１０ｈの両端で折り曲げられて形成された２本の摺動子片１０ｋとを有し、取付部１０ｈが本体部１０ａの基部１０ｃに埋設されて固定されている。これらの摺動子１０ｂは、図９に示すように、互いに反対方向を向いている。
【００３３】
このような可動体１０は、ケーシング１に短手方向にスライド移動可能に収納されている。即ち、収納部１ｅと同じ長さである凹部１０ｆが収納部１ｅと対向して空間を形成し、コイルバネ６がその空間に収納されるようになり、突起１０ｇは第２の溝部１ｄ内に挿入されると共に、コイルバネ６の端部６ａと当接した状態になっており、また、その際に端部６ａは止め部１ｈを弾圧する状態となっている。そして、可動体１０が移動すると、突起１０ｇが第２の溝部１ｄ内を移動すると共に、該突起１０ｇがコイルバネ６の端部６ａを押圧して、コイルバネ６が縮むようになっている。また、可動体１０への操作力が解除されると、コイルバネ６の復帰力によって、端部６ａによって突起１０ｇが付勢されて、可動体１０が中立位置に復帰する。なお、可動体１０が中立位置にあるときは、貫通孔１０ｄと、プッシュスイッチＰが高さ方向で一直線上に位置する状態となっている。
【００３４】
摺動子１０ｂは、可動体１０が中立位置にあるときは、摺動子片１０ｋが露出部１ｋ上に摺接しており、可動体１０が移動することで、２個の摺動子片１０ｋが移動して、第１、第２の固定接点３ａ、３ｂ間を導通してＯＮ信号が出力される。また、可動体１０がコイルバネ６に付勢されて中立位置に復帰すると、摺動子片１０ｋは再び露出部１ｋ上に摺接し、ＯＦＦとなる。このような構成によって、１組のスライドスイッチＳが形成されている。
【００３５】
押圧部材１０ｍは、金属材からなり、矩形状をなしている。このような押圧部材１０ｍは、可動体１０の貫通孔１０ｄ内に上下動可能に収納され、ドームバネ４を押圧可能となっている。
【００３６】
カバー１１は、金属板をプレス加工した後に、折り曲げ加工したものから構成され、平板状の板状部１１ａと、該板状部１１ａの中央部に形成された正方形状の第１の通孔１１ｂと、この第１の通孔１１ｂの両側近傍に設けられた矩形状の第２の通孔１１ｃと、板状部１１ａの側縁に複数個設けられたＬ字状の脚部１１ｄとを有する。
【００３７】
このようなカバー１１は、脚部１１ｄがケーシング１の側壁部にスナップ止めれることで、ケーシング１に固定されている。そして、第２の通孔１１ｃを保持部１０ｅが貫通して、上方に突出した状態となっている。また、カバー１１は、ケーシング１と協同して、可動体１０をスライド可能に保持している。
【００３８】
操作体１５は、合成樹脂の成型品からなり、図７、８に示すように、細長の矩形状の基体１５ａと、この基体１５ａの両端から垂下して形成された側壁部１５ｂとを有し、基体１５ａは、上面の中央に形成された円状の凹部１５ｃと、この凹部１５ｃの両側近傍に一対形成された短手方向に延びる第１の連通孔１５ｄと、この第１の連通孔１５ｄに隣接して設けられた第２の連通孔１５ｅとを有し、第１の連通孔１５ｄの中間部には、基体１５ａの長手方向に延びるように丸棒状の軸部１５ｈが形成されている。また、基体１５ａの下面の中央部には、２本の鉤状の突起が対向した状態で下方に延びて保持部１５ｆが形成されており、側壁部１５ｂの下端部には、互いに向かい合うように半円状の係合爪１５ｇが形成されている。
【００３９】
付勢部材たるねじりバネ１６は、巻回部１６ａと、巻回部１６ａの両端から離れる方向に延びる一対の第１、第２のアーム部１６ｂ、１６ｃとを有し、巻回部１６ａが操作体１５の保持部１５ｆに掛け止めされ、第１、第２のアーム部１６ｂ、１６ｃが操作体１５の下面に当接した状態で、このねじりバネ１６は操作体１５に保持されている。
【００４０】
このようにねじりバネ１６が保持された操作体１５は、係合爪１５ｇがケーシング１の係合凹部１ｇ内に係合することで、ケーシング１に回動可能に保持される。また、ねじりバネ１６は、巻回部１６ａが押圧部材１０ｍの上面に押し付けられた状態となり第１、第２のアーム部１６ｂ、１６ｃで操作体１５を上方に付勢している。即ち、押圧部材１０ｍがドームバネ４の頂部で弾圧保持されて押付部となっている。また、操作体１５は、係合爪１５ｇがケーシング１の係合凹部１ｇ内で上下動可能となっているので、ケーシング１に対して上下動可能となっており、この操作体１５は、ねじりバネ１６によって上方に付勢されて、係合爪１５ｇが係合凹部１ｇの頂面に当接した状態となっている。
【００４１】
また、軸部１５ｈは、可動体１０の保持部１０ｅにガイドされた状態で挿入されるが、ねじりバネ１６が操作体１５を上方に付勢し、操作体１５の回転半径が決まっているので、図２に示すように、保持部１０ｅの先端部付近に位置する状態となり、下方に移動可能なスペースが形成された状態になっている。
【００４２】
このような操作体１５が回動されると、図１１、１２を参照するに、軸部１５ｈが保持部１０ｅを水平方向に押圧することで、可動体１０が、カバー１１とケーシング１にガイドされてスライド移動し、摺動子片１０ｋが第１、第２の固定接点３ａ、３ｂ間を導通させて、ＯＮ信号が出力されるようになっている。この時、突起１０ｇにより、コイルバネ６が付勢されて可動体の移動方向に縮んでいるので、操作力が解除されると、コイルバネ６が復帰して、突起１０ｇが付勢されて、可動体１０が中立位置に復帰するようになっている。このようにして、スライドスイッチＳの操作が行われるようになっている。
【００４３】
また、操作体１５は、ケーシング１に対して上下動可能となっているので、この操作体１５が下方に押圧されると、軸部１５ｈが保持部１０ｅ内でガイドされると共に、係合部１５ｇがケーシング１の係合凹部１ｇ内でガイドされて、下方に移動すると共に、ねじりバネ１６が押圧部材１０ｍを下方に押圧し、シート５を介してドームバネ４が押圧され、プッシュスイッチＰが操作されるようになっている。そして、押圧力が解除されると、ドームバネ４が反転して、押圧部材１０ｍが上方に移動すると共に、ねじりバネ１６が上方に移動して、操作体１５が元の状態に復帰するようになっている。
【００４４】
本発明の回動操作型電気部品は、上記のような構成を有し、次にその動作について、図１１、図１２に基づいて説明すると、操作体１５が回動操作されると、係合爪１５ｇを回動中心として回動し、軸部１５ｈによって可動体１０が回動方向と同一の方向に直線的にスライド移動して、摺動子１０ｂが移動することで、電気信号が出力される。このように、回動中心を軸部１５ｈと保持部１０ｅとの挿入位置に対して、下方にすることで、回動半径を稼ぎ、可動体１０の移動量を大きくつつ、薄型化を図ることができるようになっている。さらに、操作体１５はねじりバネ１６により上方に付勢された状態になっているので、ガタツキがない。また、ねじりバネ１６は操作体１５に追従するので、両者間で摩擦が発生することがなくねじりバネ１６が傷つくことがない。
【００４５】
また、操作力が解除されると、コイルバネ６により可動体１０自身が押圧されて、可動体１０が中立位置に復帰してＯＦＦ状態となる。このようにコイルバネ６で、可動体１０そのものを復帰させるので、確実に中立位置に復帰させることができる。なお、可動体１０が移動することで、押圧部材１０ｍが下方に付勢された状態で連動するが、シート５上を移動するので、ドームバネ４が傷つくことはない。
【００４６】
また、操作体１５が下方に押圧されると、押圧部材１０ｍが押圧されて、プッシュスイッチＰがＯＮ状態となる。また、押圧力が解除されると、ドームバネ４が反転して、プッシュスイッチＰがＯＦＦ状態となる。また、図１２に示すように、操作体１５が回動しても、ねじりバネ１６は押圧部材１０ｍに当接するようになっているので、プッシュスイッチＰを操作することが可能である。
【００４７】
本発明の回動操作型電気部品は、上記のような構成、動作をなすが、上記説明した形態に限られないのはいうまでもなく、上記形態では、ケーシング１に導電パターンたる固定接点３ａ、３ｂが形成され、可動体１０に摺動子１０ｂが取り付けられているが、ケーシング１に摺動子を設け、可動体１０に導電パターンを形成しても良い。また、プッシュスイッチＰがない形態であっても良い。この時は、押圧部材は上下動可能でなくても良く、或いは可動体１０の本体部１０ａの一部であっても良い。さらに、導電パターンを抵抗体として、可変抵抗器を構成するようにしても良い。
【００４８】
【発明の効果】
本発明の回動操作型電気部品は、操作体の回動操作時、可動体がスライド移動して接点切換が行われると共に、コイルバネが縮み、操作力が解除されることでコイルバネの弾性によって可動体が復帰する構成としたため、可動体が直接コイルバネによって復帰するので、確実に中立位置に復帰させることができると共に、接点切換も行えるので、信頼性の高い回動操作型電気部品を提供することができる。
【００４９】
また、本発明の回動操作型電気部品の操作体は、押圧部材に押し付けられた付勢部材によって付勢された状態でケーシングに回動可能に保持されている構成としたため、ケーシングと操作体間のガタツキがない状態で操作体を回動できる。
【００５０】
また、本発明の回動操作型電気部品の付勢部材は操作体に保持され、該付勢部材は操作体と共に回動可能となっている構成としたため、付勢部材が操作体と共に移動するため、操作体と付勢部材との間の摩擦が起こらないので、部品の変形がなく、長寿命の回動操作型電気部品を提供することができる。
【００５１】
また、本発明の回動操作型電気部品の操作体はケーシングに対して上下動可能に保持され、該操作体が押圧されることで付勢部材を介してプッシュスイッチが操作される構成としたため、操作体で操作可能なプッシュスイッチ付きの回動操作型電気部品を提供することができる。
【００５２】
また、本発明の回動操作型電気部品の操作体が押圧されることで、付勢部材が押圧部材を押圧してプッシュスイッチが操作される構成としたため、可動体を操作体とケーシングの間に配置した状態で、プッシュスイッチを操作することが可能となる。
【００５３】

The operation body 15 is formed of a synthetic resin molded product, and as shown in FIGS. 7 and 8, has an elongated rectangular base body 15a and side wall portions 15b formed by hanging from both ends of the base body 15a. The base body 15a includes a circular recess 15c formed at the center of the upper surface, a pair of first communication holes 15d extending in the short direction formed near both sides of the recess 15c, and the first communication holes 15d. And a second communicating hole 15e provided adjacent to the first communicating hole 15d. A round bar-shaped shaft portion 15h is formed in the middle of the first communicating hole 15d so as to extend in the longitudinal direction of the base body 15a. . Further, a holding portion 15f is formed at the center portion of the lower surface of the base body 15a so as to extend downward with two hook-shaped projections facing each other, and the lower end portion of the side wall portion 15b faces each other. A semicircular engagement claw 15g is formed.
[0039]
The torsion spring 16 as an urging member has a winding portion 16a and a pair of first and second arm portions 16b and 16c extending in a direction away from both ends of the winding portion 16a, and the winding portion 16a is operated. The torsion spring 16 is held by the operating body 15 in a state in which the first and second arm parts 16 b and 16 c are in contact with the lower surface of the operating body 15.
[0040]
Thus, the operating body 15 holding the torsion spring 16 is rotatably held by the casing 1 when the engaging claw 15 g engages with the engaging recess 1 g of the casing 1. The torsion spring 16 is in a state in which the winding portion 16a is pressed against the upper surface of the pressing member 10m, and the operating body 15 is urged upward by the first and second arm portions 16b and 16c. That is, the pressing member 10m is held by the top of the dome spring 4 to form a pressing portion. Further, the operating body 15 can move up and down with respect to the casing 1 because the engaging claw 15g can move up and down in the engaging recess 1g of the casing 1, and the operating body 15 is twisted. The engaging claw 15g is in contact with the top surface of the engaging recess 1g by being biased upward by the spring 16.
[0041]
The shaft portion 15h is inserted while being guided by the holding portion 10e of the movable body 10, but the torsion spring 16 biases the operating body 15 upward, and the rotational radius of the operating body 15 is determined. As shown in FIG. 2, the holding portion 10 e is positioned near the tip, and a space is formed that is movable downward.
[0042]
When the operating body 15 is rotated, as shown in FIGS. 11 and 12, the movable body 10 guides the cover 11 and the casing 1 by the shaft portion 15 h pressing the holding portion 10 e in the horizontal direction. As a result, the sliding piece 10k conducts between the first and second fixed contacts 3a and 3b, and an ON signal is output. At this time, the coil spring 6 is urged by the projection 10g and contracts in the moving direction of the movable body. Therefore, when the operating force is released, the coil spring 6 is restored and the projection 10g is urged to move the movable body. 10 returns to the neutral position. In this way, the operation of the slide switch S is performed.
[0043]
Since the operating body 15 can move up and down with respect to the casing 1, when the operating body 15 is pressed downward, the shaft portion 15h is guided in the holding portion 10e and the engaging portion. 15 g is guided in the engaging recess 1 g of the casing 1 and moves downward, the torsion spring 16 presses the pressing member 10 m downward, the dome spring 4 is pressed via the seat 5, and the push switch P is operated. It has come to be. When the pressing force is released, the dome spring 4 is reversed, the pressing member 10m moves upward, the torsion spring 16 moves upward, and the operating body 15 returns to its original state. ing.
[0044]
The rotating operation type electric component of the present invention has the above-described configuration. Next, the operation thereof will be described with reference to FIGS. 11 and 12. When the operating body 15 is rotated, The claw 15g is rotated around the rotation center, and the movable body 10 is linearly slid and moved in the same direction as the rotation direction by the shaft portion 15h, and the slider 10b is moved, so that an electric signal is output. The In this way, by turning the rotation center downward with respect to the insertion position of the shaft portion 15h and the holding portion 10e, the rotation radius can be increased and the moving amount of the movable body 10 can be increased, and the thickness can be reduced. Can be done. Furthermore, since the operating body 15 is biased upward by the torsion spring 16, there is no backlash. Further, since the torsion spring 16 follows the operating body 15, no friction is generated between them, and the torsion spring 16 is not damaged.
[0045]
When the operating force is released, the movable body 10 itself is pressed by the coil spring 6, and the movable body 10 returns to the neutral position and enters the OFF state. Since the movable body 10 itself is returned by the coil spring 6 in this way, it can be reliably returned to the neutral position. Although the movable body 10 moves in conjunction with the pressing member 10m biased downward, the dome spring 4 is not damaged because it moves on the seat 5.
[0046]
When the operating body 15 is pressed downward, the pressing member 10m is pressed and the push switch P is turned on. When the pressing force is released, the dome spring 4 is reversed and the push switch P is turned off. As shown in FIG. 12, even if the operating body 15 rotates, the torsion spring 16 comes into contact with the pressing member 10m, so that the push switch P can be operated.
[0047]
The rotating operation type electric component of the present invention has the above-described configuration and operation. However, it is needless to say that the rotating operation type electric component is not limited to the above-described embodiment. 3b is formed, and the slider 10b is attached to the movable body 10, but a slider may be provided in the casing 1 to form a conductive pattern on the movable body 10. Moreover, the form without the push switch P may be sufficient. At this time, the pressing member may not be movable up and down, or may be a part of the main body 10 a of the movable body 10. Furthermore, a variable resistor may be configured using the conductive pattern as a resistor.
[0048]
