Description

【0001】
【発明の属する技術分野】
本発明は、スイッチの内部に収納される照光ブロックの製造方法に関するものである。
【0002】
【従来の技術】
従来から、ハンドル部の押圧操作により、内部のスイッチ接点部を切り換えるようにしたスイッチが知られており、このようなスイッチ内部には、このスイッチの存在を示すために、スイッチの状態に応じて発光するネオンランプを備えた照光ブロックが内装されている。
【0003】
この照光ブロックを組み立てるときの従来例を図24の上面図を用いて示す。図24(a)に示されるプリント基板81のパターン形成された各実装部位82上に図24(b)に示すようにネオンランプ83、抵抗素子84、接触ばね85などの各部品が手組みで実装され、分断部87で所定の形状に分断されて、個々の照光ブロックが組み立てられていた。図25はそれぞれ組み立てられた照光ブロック86の(a)は上面図、(b)は側面図、(c)は正面図であり、図23と同じものには同じ符号を付している。
【0004】
【発明が解決しようとする課題】
しかし、このような従来の構成では、プリント基板上に各部品を手組みにより実装していくようにしているのでその組立加工のコストが高くなるという問題があった。
【0005】
本発明は上記事由に鑑みて為されたものであり、その目的は安価な組み立ての実現される照光ブロックの製造方法を提供することにある。
【0006】
【課題を解決するための手段】
上記課題を解決するために請求項1の発明は、接点部の切り換えを行うスイッチ機構を備えたスイッチの内部に収納され、リード板がインサート成形された樹脂基体からなり、前記リード板により前記接点部に電気的に接続される端子部が形成され、前記樹脂基体上に載置されるとともに前記端子部と電気的に接続され、前記接点部の切り替わり状態に応じて点灯状態が切り替わるランプと、前記リード板の所定の位置に半田付けされ前記ランプに流れる電流を制限する抵抗素子とを備える照光ブロックの製造方法であって、前記リード板は複数個の部位が連続して連なっており、樹脂に前記各部位がそれぞれインサート成形された後、各部位毎に分断されて個々の前記樹脂器基体となり、前記分断された各部位は、周囲にリード板からなる略長方形状の枠体が、内部に前記樹脂基体が前記枠体と一体に形成されるように構成され、前記枠体の相対向する辺のそれぞれには前記リード板の面と略垂直方向に立ち起こされる立ち起こし片が設けられ、前記分断された各部位の枠体の相対向する辺が隣接するように自動機上に載置され自動送りされて前記抵抗素子が半田付けされ、この自動送りのとき各部位に設けられたそれぞれの立ち起こし片どうしが接触して各部位どうしが重ならないようにされることを特徴とする。
【0011】
また、請求項の発明は、請求項記載の発明において、前記分断された各部位は自動機により自動送りされてリフロー炉に流され、各部位の所定の位置に前記抵抗素子が半田付けされることを特徴とする。
【0013】
また、請求項の発明は、請求項1,2記載の発明において、最終工程で前記枠体より前記樹脂基体が切り離されて照光ブロックとされることを特徴とする。
【0014】
【発明の実施の形態】
本発明のピアノハンドル式スイッチに用いられる照光ブロックの組み立て方法を説明する。図2,図4は点線A−A’で区切られるように個々の照光ブロックを形成するための同一形状のリード板部位3が複数個連なるリード板2を示す斜視図、および上面図であり、その略中央部には後述する抵抗素子の端子と電気的に接続される端子片5a,5b、他の抵抗素子の端子と電気的に接続される端子片6a,6bが形成されている。端子片5a,6aからリード板部位3の上端部12へ延びる延設片8a,8bはその端部8でつながっており、後の工程で切断されてそれぞれが後述するネオンランプの端子となる。
【0015】
そして、延設部8aの略中間部からリード板部位3の左端部9へ連なる線部10aは後の工程で切断され、また延設部8bの中間部よりリード板部位3の右端部11へ延びる線状部7aは後の工程で右端部11近辺で切断されて後述する接触ばねとなる。
【0016】
また、端子片5b,6bとは連設片14を介してつながっており、連設片14より左端部9へ延びる線部10b、下端部13へ延びる線部10cは後の工程で切断され、連設部14より右端部11へ延びる線状部7bは後の工程で右端部11近辺で切断されて後述する接触ばねとなる。そしてまた、右端部11の中央付近よりリード板部位3の中央に向かって線状片15が設けられる。
【0017】
まず最初の工程で、図3の斜視図、図5の上面図に示すように樹脂にリード板2がインサート成形され、各リード板部位3毎に略T字状の樹脂基体4が形成される。この樹脂基体4は上記したリード板部位3の上端部12に向かって延設部8a,8bが、下端部13に向かって線部10cが延びるように、左端部9に向かって線部10a,10bが、右端部11に向かって線状部7a,7bおよび線状片15が延びるように構成される。
【0018】
この樹脂基体4の中央部には、上記した抵抗素子の端子が接続される端子片5a,5bおよび端子片6a,6bが露出しており、端子片5a,5bのそれぞれの左端部9側の端部には上方に突出する突出部16,16が樹脂基体4と一体に形成されるとともに、端子片5a,端子片6aの中間部から端子片5b,端子片6bの中間部にかけて上方に突出する突出片部17が樹脂基体4と一体に形成される。また、樹脂基体4の上端部12側の端部には上方に突出する突起18a,18cが、下端部13側の端部には上方に突出する突起18b,18dが形成され、そして樹脂基体4の右端部11側には上方に突出する突起部20および突起19a,19bが形成される。
【0019】
次の工程では、上記したようにインサート成形されたリード板2が図5の上面図に示されるように、点線部A−A’により各リード板部位3毎に分断される。このとき、リード板部位3の右端部11と右隣に隣接するリード板部位3’の左端部9’との間に設けられた4つの片のうち、リード板2の上端と下端に設けられる上端片21a,下端片21bは切り取られ、上端近辺に設けられた端片22と下端近辺に設けられた端片23とは、点線A−A’で示される中間で切断され、端片22からリード板部位3には右端片22aが、リード板部位3’には左端片22bが形成され、端片23からリード板部位3には右端片23aが、リード板部位3’には左端片23bが形成される。
【0020】
このとき、リード板部位3においても同様に、左端部9側に左端片22b,23bが形成される。そして、リード板部位3の右端片22a,23aと左端片22b,23bは、リード板部位3の面と略垂直方向に立ち起こされる立ち起こし片となる。図1の斜視図、図6の上面図はリード板2が分断され、図5で述べたように各リード板部位3の相対向する辺3A,3Bのそれぞれに設けられた左端片22b,23b、右端片22a,23aが立ち起こされたところを示している。
【0021】
このように分断される工程では、図5に示される上記したリード板部位3の端部8は、略中央部よりリード板部位3の上端部12側の端部片8cが切り取られ、下端部13側の端部片8dはその中間部より左右に切断されて、左片8eと右片8fが形成され、左片8eと右片8fのそれぞれは図1,図6に示すように、後述するネオンランプの各端子を挟持するよう両端部が上方に向かって曲げられる。すなわち、上記した延設部8aの先端に片体である左片8eが、延設部8bの先端に片体である右片8fが形成される。
【0022】
そしてまた、図1、図6に示すようにリード板部位3の線部10a,10bは左端部9近辺が切り取られ、線状部7a,7bは右端部11近辺が切り取られ、後述する図7(c)の側面図に示されるように、根本24cが一旦下方に折り曲げられ、先端24dにかけて上方に向かうように折り曲げられて、それぞれ端子部である接触ばね24a,24bとなる。この状態でリード板部位3の周囲に位置する略長方形状の枠体3Cに、線部10c、線状部15を介して一体となる成形部4が内部に位置する形状となる。
【0023】
次の工程では、分断された各リード板部位3には、図7(a)(b)(c)の斜視図、上面図、側面図に示すように、抵抗素子25,26が所定の位置に載置され、図8(a)の上面図、図8(b)の側面図に示されるように、図示せぬ自動機上に各リード板部位3の右端部11と左端部9がほぼ接するように載置され自動送りされてリフロー炉に流されて、チップ型の抵抗素子25,26が各リード板部位3の所定の位置に半田付けされる。
【0024】
このとき、図1に示される上記した突出部16の右端部11側に設けられる斜面と突出片部17の左端部9側の斜面17a間に抵抗素子25の端子25a,25bがそれぞれ端子片5a,5bに接するように載置され、端子片6a,6bの右端部11側に位置する樹脂基体4に設けられた斜面4aと突出片部17の右端部11側の斜面17b間に抵抗素子26の端子26a,26bがそれぞれ端子片26a,26bに接するように載置される。
【0025】
また、上記した突出部16の斜面と突出片部17の斜面17a間の距離は上方から抵抗素子25の載置される下方にかけて幅が狭くなるように互いに傾斜し、抵抗素子25の載置されるところの突出部16と突出片部17との距離は抵抗素子25の短手方向の寸法と略等しくされる。そしてまた、突出片部17の斜面17bと上記した斜面4aとは、上方から抵抗素子26が載置される下方にかけて幅が狭くなるように互いに傾斜し、抵抗素子26の載置されるところの突出片部17と斜面4aとの距離は抵抗素子26の短手方向の寸法と略等しくされる。尚、図1は載置される前の状態を示している。
【0026】
この突出部16、突出片部17、斜面4aにより突出部位が構成され、この突出部位のために、各抵抗素子25,26の実装位置の位置決めができ、各リード板部位3を自動機により自動送りする際に、抵抗素子25,26が自動送りの際の振動により外部に飛び出さないようにできる。
【0027】
図12(a),(b)はそれぞれ抵抗素子25,26の実装部27に突出部位を設けず、フラット形状としたときの抵抗素子25,26の実装前と実装後の状態を示した斜視図であり、突出部位がないため、各リード板部位3を自動機により自動送りする際に、振動により抵抗素子25,26が外部に飛び出してしまう可能性がある。
【0028】
また、図8に示すように各リード板部位3を自動機により自動送りする際、リード板部位3の立ち起こし片である右端片22a,23aと左端片である22b,23bが設けられる相対向する辺3B,3Aのうちの辺3Bと、リード板部位3’の同じく立ち起こし片が設けられる相対向する辺3’A,3’Bのうちの辺3’Aが隣接するように自動機上に複数のリード板部位が載置される。このように自動送りされるとき、上記したリード板部位3の右端部11より立ち起こされた右端片22a,23aと、リード板部位3’の左端部9より立ち起こされた左端片22b,23bが接触することで、リード板部位3が隣のリード板部位3’の上に乗り上げて各リード部位3,3’同士が重なりあうことがなくなり、工程がつまったり、リード板部位3を持ち上げる際に隣のリード板部位が持ちあがることもなくなる。
【0029】
図13(a)(b)(c)はそれぞれ、上記した右端片22a,23a、左端片22b,23bを設けない場合のリード板部位3の斜視図、上面図、側面図を示しており、図7と同じものには同じ符号を付し、その説明を省略する。図14(a)(b)は図13に示される各リード板部位3を自動機により自動送りするときの状態を示す上面図と側面図であり、上記した立ち起こし片がないために図示されるように各リード板部位3の右端部11と左端部9とが重なりあってしまう可能性が生じる。すると、上記したように工程がつまったり、リード板部位3を持ち上げる際に重なりあった隣のリード板部位が持ち上がってしまうことがある。
【0030】
次の工程では、図9の上面図に示すように、樹脂基体4の上部にネオンランプ28が載置され、樹脂基体4より延びている上記した延設部8a,8bが根本近傍より上方に折り曲げられ、延設部8aの先端に設けられた左片8eにネオンランプ28の端子28aが、延設部8bの先端に設けられた右辺8fにネオンランプ28の端子28bが挟持される。これにより、ネオンランプ28は上記した端子片5a,5b上の抵抗素子25、端子片6a,6b上の抵抗素子26、および端子部である接触ばね24a,24bとリード板部位3を介して電気的に接続される。この抵抗素子25,26はネオンランプ28に流れる電流を制限するよう作用する。
【0031】
最後に、上記したように樹脂基体4よりリード板部位3の下端部13側に延びる線部10cと、樹脂基体4よりリード板部位3の右端部11側に延びる線状部15とが、図9で示される樹脂基体4の近辺より切断され、枠体3Cより樹脂基体4が切り離されて図10の斜視図、図11の上面図に示されるように照光ブロック1が完成する。
【0032】
この照光ブロック1をスイッチ機構を備えたスイッチであるピアノハンドル式スイッチに組み込んだときの構造を、図15の分解斜視図、図16,図17の断面図、図18の正面図、図19の側面図、図20,図21の上面図、図22の構造図を用いて説明する。尚、各図において図15から図20はピアノハンドルを押釦スイッチに取り付けていない状態を示し、図22はピアノハンドルを取り付けた状態を示している。また、図17の断面図は図16の押釦スイッチの一部の詳細を示した状態を、図21の上面図は押釦スイッチのボディに部品を挿入した状態を示している。各図において同じものには同じ符号を付している。
【0033】
このピアノハンドル式スイッチは、押釦ハンドル32の押圧操作により接点部の接点切換が行われるスイッチである押釦スイッチ55と、この押釦スイッチ55の上面に一端部が回動自在に枢支され他端部を押圧して押釦ハンドル32を押圧操作するピアノハンドル45とからなる。押釦スイッチ55の器体は、合成樹脂製のボディ55bとカバー55aとで形成されており、JIS規格等において規格化されている既製の埋込型の配線器具の1個モジュール寸法に形成してある。
【0034】
そして、押釦スイッチ55の表面側の部材であるカバー55aには、既製の配線器具を埋設する場合に用いる図示せぬ取付枠に着脱自在に取付可能とするために、両端面に一対の係止爪51を夫々突設してあり、一方の係止爪51の背部には空所52を形成し、係止爪51が背方へ弾性的に撓むようにしてある。したがって、既製の配線器具用の取付枠に係止爪51を係止させて押釦スイッチ55を着脱自在に取り付けることができ、既製の埋込型の配線器具と同様にして壁面などの造営面に埋設できるようにしてある。
【0035】
ボディ55bとカバー55aの結合は、カバー55aより垂下した係止片53の係止孔54にボディ55bの側面に形成してある係止突起56を係止させることにより行っており、係止時には係止片53の弾性と係止突起56の上端の傾斜面56aを利用して簡単に係止できるようになっている。この押釦スイッチ55のボディ55b内の一端部に接続端子収納部63を、他端部に接続端子収納部64を形成し、更に中央部に中央収納部73を形成してある。そして、一端部の接続端子収納部63には共通端子板65、鎖錠ばね71及び解除釦70からなる速結端子が収納され、他端部の接続端子収納部64には端子板68aと鎖錠ばね71からなる接続端子部と、端子板68bと鎖錠ばね71からなる接続端子部と、図示せぬ解除釦が収納される。
【0036】
ここで、図17に示すように、端子板68aにはその先端部に固定接点75aが固着し、端子板68bの先端部には固定接点75bが固着している。また共通端子板65から中央収納部73に支持片65aが延出してあり、導電体からなる開閉体74が中央収納部73内に入れられてその下端が支持片65a上に回動自在に立設してある。ここで、開閉体74の両端下部に設けた突部を中央収納部73の内側壁に形成されたV状凹部77に嵌め込んで、V状凹部77の下部を中心に回動自在となっている。
【0037】
開閉体74の先端部両側には可動接点79a,79bが設けられており、開閉体74の回動に応じて固定接点75aと可動接点79aの接触、および固定接点75bと可動接点79bの接触を切り換える。このとき、可動接点79a,79b、固定接点75a,75bにより接点部が構成され、この接点部の切り換えを行うための開閉体74は反転ハンドル31の反転回動により操作されるように構成してある。
【0038】
すなわち、反転ハンドル31の下部には下方に開口した筒部31aが並設してあり、筒部31aにはコイルスプリング41の上部が納められ、コイルスプリング41の下部が開閉体74の上縁に係止され、反転ハンドル31の回動に応じて開閉体74を反転駆動するようになっている。反転ハンドル31は両側に設けた三角形状の軸31bをカバー55aの内壁に形成された軸受42に枢支して回動自在に取り付けられ、上部の両端にスライドカム33に掛合する掛合突起34を突設してある。押釦ハンドル32はカバー55aに上下動自在に取り付けられ、下方に配置される復帰ばね37により常時上方に付勢されている。
【0039】
スライドカム33は両端下面に反転ハンドル31の掛合突起34に摺動係合する掛合カム体38が形成され、押釦ハンドル32の下面側において摺動自在に取り付けられており、内部に形成されたハ状の一対のばね片33aの間に押釦ハンドル32の下面に形成している突起(図示せず)が挿入され、このばね片33aで復帰力を与えている。
【0040】
押釦スイッチ55の器体のカバー55aの表面側端部には、上部が横向きの略円柱状をした軸部43が所定間隔をあけて2つ一体突設してある。図22に示すように、軸部43をピアノハンドル45の裏面部の一端部に設けられた軸受部44に回動自在に嵌め込んで、ピアノハンドル45を回動自在に軸支している。ここで、ピアノハンドル45を押圧操作すると、軸部43と軸受部44を中心にしてピアノハンドル45がピアノタッチ式に回動し、押釦スイッチ55の押釦ハンドル32を押圧操作する。また、ピアノハンドル45の他端部には抜け止め用の抜止片46を突設している。
【0041】
上記押釦スイッチ55の動作を簡単に説明する。図16,17の状態は固定接点75bが可動接点79bに接している状態である。この状態で、ピアノハンドル45を操作すると、ピアノハンドル45の操作に伴って押釦ハンドル32が復帰ばね37に抗して押し下げられ、押釦ハンドル32の押し下げによりスライドカム33が下降する。そして、スライドカム33の図中左側の掛合カム体38が、反転ハンドル31の左側の掛合突起34に当たることにより、反転ハンドル31が回動する。このとき、反転ハンドル31の回動に伴ってスライドカム33が図中の左側にスライドする。このようにして反転ハンドル31が反転回動されると、コイルスプリング41が反転して開閉体74が反転し、可動接点79aが固定接点75aに接する状態となる。
【0042】
この反転後、ピアノハンドル45の押し下げ力を解除すると、復帰ばね37で押釦ハンドル32が押し上げられ、ピアノハンドル45が元の状態に戻る。そして、これと同時にスライドカム33もばね片33aのばね力で中央部に摺動復帰する。この状態から再びピアノハンドル45を押し下げ操作すると、上記とは逆に反転ハンドル31が回動して接点部が切り替わる。
【0043】
また、上記した照光ブロック1は、その端子部である接触ばね24a,24bがそれぞれ端子板68a,68bに電気的に接続されるように、端子板68a,68bの上部に載置され、カバー55aにより上部から押圧されて固定される。これにより、照光ブロック1の接触ばね24a,24bは上記した固定接点75a,75bと電気的に接続される。そして、2つの軸部43の中間部にある略長方形状のレンズ部47より照光ブロック1のネオンランプ28からのランプ光が外部に出される。
【0044】
この照光ブロック1の内部回路図を図23に示す。スイッチSは点Eに接続される共通接点Iが、点Dに接続される接点Gあるいは、点Fに接続される接点Hに切り替わるよう構成され、接点Gと接点H間には抵抗素子25とネオンランプ28の直列回路と抵抗素子26との並列回路が接続される。点E、点D間に例えば図示せぬ電源と照明器具などの負荷が直列接続されている場合、スイッチSの共通接点Iが接点Gに接続されると、電源→照明器具→点E→共通接点I→接点G→点Dの閉ループ回路ができ照明器具が点灯し、接点Hに接続される場合は電源→照明器具→点E→共通接点I→接点H→ネオンランプ28→抵抗素子25→点Dの閉ループ回路ができ、照明器具が消灯しネオンランプ28が点灯する。このとき、抵抗素子25を大きな値とし、ネオンランプ28は低電流でも点灯するものとする。上記したように、照光ブロック1の接触ばね24a,24bが端子板68a,68bに電気的に接触することで、ネオンランプ28と抵抗素子25の直列回路と抵抗素子26とが接点G,Hに並列に接続されることになる。尚、図23において図1から図9と同じものには同じ符号を付している。ここで、スイッチSは上記した開閉体74に相当し、開閉体74の反転による上記した接点部の切り替わりにより、ネオンランプ28の点灯状態が切り替わる。また、3路スイッチとして他のスイッチと組み合わせて使用できる。
【0045】
【発明の効果】
上記したように請求項1記載の発明では、接点部の切り換えを行うスイッチ機構を備えたスイッチの内部に収納され、リード板がインサート成形された樹脂基体からなり、前記リード板により前記接点部に電気的に接続される端子部が形成され、前記樹脂基体上に載置されるとともに前記端子部と電気的に接続され、前記接点部の切り替わり状態に応じて点灯状態が切り替わるランプと、前記リード板の所定の位置に半田付けされ前記ランプに流れる電流を制限する抵抗素子とを備える照光ブロックの製造方法であって、前記リード板は複数個の部位が連続して連なっており、樹脂に前記各部位がそれぞれインサート成形された後、各部位毎に分断されて個々の前記樹脂器基体となるため、効率よくインサート成形により安価で照光ブロックを製造できる。また、前記分断された各部位は、周囲にリード板からなる略長方形状の枠体が、内部に前記樹脂基体が前記枠体と一体に形成されるように構成され、前記枠体の相対向する辺のそれぞれには前記リード板の面と略垂直方向に立ち起こされる立ち起こし片が設けられ、前記分断された各部位の枠体の相対向する辺が隣接するように自動機上に載置され自動送りされて前記抵抗素子が半田付けされ、この自動送りのとき各部位に設けられたそれぞれの立ち起こし片どうしが接触して各部位どうしが重ならないようにされるため、各部位を自動機で自動送りするときに各部位どうしが重なりあうことを防止することができ、製造工程がつまることを防止できる。
【0050】
また、請求項記載の発明では、請求項記載の照光ブロックの製造方法において、前記分断された各部位は自動機により自動送りされてリフロー炉に流され、各部位の所定の位置に前記抵抗素子が半田付けされるため、効率よく安価で照光ブロックを製造できる。
【0052】
また、請求項記載の発明では、請求項1,2記載の発明において、最終工程で前記枠体より前記樹脂基体が切り離されて照光ブロックとされるため、請求項記載のように枠体に立ち起こし片を設けて枠体を有効に使用できる。
