【発明の属する技術分野】
本発明は、自動車における自動変速機のシフトレバーの切換操作で、パーキング、リバース、ニュートラル、ドライブ、2速、1速というようなシフトポジションに応じたスイッチ切り換えを行なう自動変速機用コントロールスイッチの製造方法に関するものである。
【0002】
【従来の技術】
従来より自動変速機を備えた自動車では、シフトレバーの切換操作でパーキング、リバース、ニュートラル、ドライブ、2速、1速というような自動変速機のシフトポジションを示すポジション信号を発生したり、スタートモータの通電路のオン・オフや、バックライトのオン・オフを行なうための自動変速機用コントロールスイッチが用いられている。
【0003】
この種の自動変速機用コントロールスイッチの一例としては、図16〜図19に示すようにアルミダイカスト製のカバー51aとカバー51aにゴムパッキン66を介して被着される合成樹脂製のベース51bとから成るハウジング51と、このハウジング51の内部に回動自在に収められる可動体60とを備え、ハウジング51が図21に示すように自動変速機ATMに取り付けられるとともに、シフトレバーの操作に応じて回動するシフト切り換え用のマニュアルシャフト41に可動体60が固定されるものがある。
【0004】
可動体60はシフトレバーの回動に応じてマニュアルシャフト41と一体的に回動するもので、マニュアルシャフト41に固定される軸部61と、軸部61から突設されてカバー51aの凹部52で形成される空間内を回動する合成樹脂製の接点ホルダ62とを有し、締め付け用ナット6を用いて軸部61がマニュアルシャフト41に締め付け固定される。接点ホルダ62は内部にスプリング64で付勢された可動接点63A,63Bを収納している。またハウジング51には軸部61を回動自在に枢支する軸受部53が設けてある。この軸受部53の内周面に環状に形成した凹部には環状のゴムシール65a,65bが装着されている。
【0005】
ベース51bの内側面には可動体60の回動中心を中心とする4つの同心円周上に弧状の固定接点54a、54b1 …,54c、54d1 …を夫々インサートにより配置し、これらこれら固定接点54a、54b1 …,54c、54d1 …に接続されたリード端子からなる出力回路はベース51bの外側の凹部に配設され図においてハウジング51の上端部に設けられたコネクタ部55内のコネクタ端子を介して外部に導出されるようになっている。尚ベース51bの外側の凹部は接着剤56が充填され出力回路を外部に対して密封している。

【発明が解決しようとする課題】
ところで上記従来例の自動変速機用コントロールスイッチのベース51bは、図20に示すように9本のコネクタ端子49をインサート成形してコネクタ部55を構成し、コネクタ端子49の基端からリード端子50をベース51bの成形体より露出させ、その先端に固定接点54a、54b1 …,54c、54d1 …のターミナルを半田付けするためのターミナルを設けたコネクタブロックを備え、また固定接点54a、54b1 …,54c、54d1 …をインサート成形して一方側に接点部位を露出させ、他方側にコネクタブロックのターミナルを接続するためのターミナルを露出させて該ターミナルをコネクタブロックのターミナルに半田付け接続した後、接着剤56を上記のように充填して密封シールするための凹部を持つ。
【0008】
そしてコネクタブロックを製造するための金型は、コネクタの内部形状を形成するためのサイドコアとコネクタ部55の外形を形成するための上、下金型よりなり、成形に当たっては9本のコネクタ端子49…を1本づつ金型のサイドコアに手で挿入し、その後上、下金型を閉じ、樹脂を金型内に充填してインサート成形を行なうため、作業に時間がかかり、更に作業中に端子を変形しやすい等製造が大変面倒であった。
【0009】
本発明は上記問題点に鑑みて為されたもので、請求項1の発明の目的とするところはサイドコアの移動と同時にコネクタ端子の寸法矯正が図れる自動変速機用コントールスイッチの製造方法を提供することにある。
【0010】
請求項2の発明の目的とするところは、請求項1の発明の上記目的に加えて、スライドコアによってサイドコアの移動時のクランク状の連接部位の変形を防止できる自動変速機用コントールスイッチの製造方法を提供することにある。
【0011】
【課題を解決するための手段】
上記目的を達成するために請求項1の発明では、樹脂成形品からなるベースと、このベースに被着するカバーとで構成されるハウジング内に、自動変速機のシフトレバーの切換操作に応じて回動する可動体を備え、この可動体に可動接点を一体的に取り付けるとともに可動体の回動に応じて可動接点と接触・開離する固定接点をベースの内側壁面に配設し、可動接点と固定接点の接触・開離に応じて自動変速機の各種設定に応じた切換を行なうものであって、上記固定接点を設けた導電板をインサートして固定接点を内側壁面に露設するとともに導電板に一体連接した端子を外部に露出させた1次成形体と、この1次成形体の外側壁面を覆うように1次成形体をインサートして外殻と上記端子を周壁で囲むコネクタ部とを形成した2次成形体とにより上記ベースを構成し、1次成形時に上金型と下金型が突き合わせて挟持される上記端子と導電板との連接部位を端子より細くした自動変速機用コントロールスイッチの製造方法において、2次成形時にコネクタ部形成用のサイドコアを1次成形体の端子突出部位方向に移動させる際に、1次成形体より露出した端子と導電板との連接部位の可撓性を利用しながら、サイドコアに設けた挿入穴に挿入する工程を有することを特徴とする。
【0012】
請求項2の発明では、請求項1の発明において、上記サイドコアの移動の際に、上記リブ形成用のスライドコアにより端子の上記クランク状の連接部位を支え、型閉め時にスライドコアを所定位置に移動させる工程を有することを特徴とする。
【0013】
【発明の実施の形態】
以下、本発明を実施形態により説明する。図3乃至図10は本発明の製造方法で得られた自動変速機用コントロールスイッチの構造例を示しており、本例は、アルミダイカスト製のカバー2と合成樹脂製のベース3とをリベット4で結合して組み立てられる略扇形のハウジング1と、このハウジング1の内部に回動自在に収められる可動体10とを備えている。
【0014】
可動体10は亜鉛ダイカスト製で一端に円筒形の軸部13と、スプリング14により外側へ弾性付勢された3個の可動接点15A,15B,15Cを保持する合成樹脂製の接点ホルダ12とを備え、軸部13に一体に連設された函状収納部11内に接点ホルダ12が収納固定されている。略扇形に形成されているハウジング1の要部分には可動体10の軸部13を枢支する軸受部5が設けてあり、カバー2側へ突出した軸部13の先端部分には軸部13をマニュアルシャフト(図20に示す)41に固定するための締め付け用ナット6が螺着されている。図中8はカバー2とベース3との間に介在するゴムパッキン、9は軸部13に接触して軸受け部5をシールする環状のゴムシールである。また31はハウジング1と大気とを連通させる呼吸穴で、連通穴17を設けた樹脂製キャップ18で閉塞されており、内部には空気を通過させ水を遮断するフィルターを内装している。
【0015】
ベース3は、一端部にそれぞれ後述する固定接点7a1 …、7b1 …、7 c1…、7d、7e1 …を設けた複数の導電板7…をインサート成形した1次成形体3Aをインサートして軸受部5のベース側部分及び外側壁面となる外殻及びコネクタ部20を2次成形により形成した2次成形体3Bとで構成される。各固定接点7a1 …、7b1 …、7 c1 …、7d、7e1 …は軸受部5を中心にして夫々が異なる径の5つの円周の上に配設されており、ハウジング1内で可動体10の可動に伴って、接点ホルダー14内の可動接点15Aが最も内側の第1の円周上と、その隣の第2の円周上とに跨がるように両円周に沿って移動し、また可動接点15Cが最も外側の第3の円周上と、内側において隣接する第4の円周上とに跨がるように両円周に沿って移動し、更に可動接点15Bが第4の円周と第2の円周との間の第5の円周上と第4の円周上とに跨がるように移動するようになっている。
【0016】
周壁21で囲まれ筒状に形成されたコネクタ部20の内底面には、上記固定接点7a1 …、7b1 …、7 c1 …、7d、7e1 …を設けた複数の導電板7…の先端が2列に突出されてコネクタ端子16を形成してある。そして、このコネクタ部20の根元のハウジング1外周面には高圧洗車等において、水がコネクタ部20に入るのを抑制するために水撥ねを行なうための外鍔部(フランジ部)22が設けてある。この外鍔部22は、図6に示すようにハウジング1の厚みよりも大きな幅寸法に形成されている。また外鍔部22の底面(軸受部5側の面)には複数の補強用のリブ23をその長手方向が外鍔部22の基部側から外方向に向かうように夫々形成しており、複数のリブ23を設けることで充分な強度を確保して、外鍔部22の厚みを小さくし、ハウジング1全体の小型化を図っている。
【0017】
ハウジング1には車体(あるいは自動変速機ATM)への取り付け用の取付ねじが挿通されるねじ挿通孔19が設けてある。そして、ハウジング1を車体の正規の取付位置に取り付けた状態でコネクタ部20の開口面の法線方向(図9におけるイ方向)が車体底面の法線方向(同図におけるロ方向)から所定の角度θ(θとしては30°〜60°が望ましい)だけ傾くようにコネクタ部20が設けられている。
【0018】
さて上記固定接点7a1 …、7b1 …、7 c1 …、7d、7e1 …はその接触面がベース3の表面より高い位置となるように露設されており、固定接点7a1は可動体10が図5に示すパーキングポジション(P)に回動操作された時に可動体10の可動接点5Aが接触可能なベース3の位置に露設され、導電板7及びコネクタ端子16を通じてイグニッションキースイッチのスタータ側接点を介して車載用のバッテリの非接地側電極、例えば+電極に接続される。同様に固定接点7a2 は固定接点7a1 と同じ導電板7に設けられ、可動体10がニュートラルポジション(N)に回動した時に可動体10の可動接点5Aが接触可能なベース3の位置に露設されてある。
【0019】
固定接点7b1 ,7b2 は可動接点5Aにより上記固定接点7a1 ,7a2 との間でオン・オフするもので、固定接点7b1 は可動体10がパーキングポジション(P)に回動された時に可動体10の可動接点5Aが接触可能なベース3の位置に露設されてある。
【0020】
また固定接点7b2 は固定接点7b1 と同じ導電板7に設けられ、可動体10がニュートラルポジション(N)に回動した時に可動体10の可動接点5Aが接触可能なベース3の位置に露設されてある。そして両固定接点7b1 ,7b2 は導電板7及びコネクタ端子16を通じてスタートモータの一端に接続される。
【0021】
固定接点7c1 〜7c3 と、固定接点7dとは、可動体10の可動接点5Bによりオン・オフされるもので、固定接点7c1 は可動体10がパーキングポジション(P)に回動された時に可動体10の可動接点5Bが接触可能なベース3の位置に露設され、固定接点7c2 は可動体10がニュートラルポジション(N)に回動した時に可動体10の可動接点5Bが接触可能なベース3の位置に露設され、固定接点7c3 は可動体10が2速ポジション(2)に回動した時に可動体10の可動接点5Bが接触可能なベース3の位置に露設されており、夫々の固定接点7c1 〜7c3 は夫々別の導電板7に形成され、導電板7及びコネクタ端子16を通じて夫々に対応する信号系回路の一端に接続される。
【0022】
最も外側に位置する固定接点7e1 〜7e3 は固定接点7dとの間で可動体10の可動接点5Cによりオン・オフされるもので、固定接点7e1 は可動体10がリバースポジション(R)に回動された時に可動体10の可動接点5Cが接触可能なベース3の位置に露設され、固定接点7e2 は可動体10がドライブポジション(D)に回動した時に可動体10の可動接点5Bが接触可能なベース3の位置に露設され、固定接点7e3 は可動体10が1速ポジション(L)に回動した時に可動体10の可動接点5Bが接触可能なベース3の位置に露設されており、夫々の固定接点7e1 〜7e3 は夫々別の導電板7に形成され、導電板7及びコネクタ端子16を通じて夫々に対応する信号系回路の一端に接続される。また固定接点7e1 は導電板7及びコネクタ端子16を通じて更にバックランプの一端も接続される。
【0023】
そして固定接点7dは共通固定接点を構成し、可動体10がパーキングポジション(P)〜1速ポジション(L)の範囲で移動する際に可動接点5B、5Aが共に接触可能なように長さが設定されてベース3に露設されており、該固定接点7dを形成した導電板7はスタート後に接続されるイグニッションキースイッチの接点を介して車載用のバッテリの+電極に接続される。
【0024】
ここで、固定接点7a1 …が配置された円周と、固定接点7b1 …が配置された円周との間のベース3には、固定接点7a1 ,7b1 の外側端面と同一の回動角度の端面を持ち、反固定接点7a1 ,7b1 側へ延設された円弧状のリブ321 と、固定接点7a1 ,7b1 の内側端面と同一の回動角度の端面を一端に持ち、他端に固定接点7a2 ,7b2 の内側端面と同一の回動角度の端面を持つ円弧状のリブ322 と、固定接点7a2 ,7b2 の外側端面と同一の回転角度の端面を一端に持ち、反固定接点7a2 ,7b2 側へ延設されたリブ323 とを一体突設してある。
【0025】
また固定接点7c1 …が配置された円周と、固定接点7dが配置された円周との間のベース3には、固定接点7c1 ,7dの外側端面と同一の回動角度の端面を持ち、反固定接点7c1 ,7d側へ延設された円弧状のリブ324 と、固定接点7c1 の内側端面と同一の回動角度の端面を一端に持ち、他端に固定接点7c2 の固定接点7c1 側端面と同一の回動角度の端面を持つ円弧状のリブ325 と、固定接点7c2 の固定接点7c3 側端面と同一の回動角度の端面を一端に持ち、他端に固定接点7c3 の固定接点7c2 側端面と同一の回動角度の端面を持つ円弧状のリブ326 と、固定接点7c3 の外側端面と同一の回動角度の端面を持ち、反固定接点7c3 側へ延設された円弧状のリブ327 とを一体突設してある。
【0026】
更に固定接点7e1 …が配置された円周と、固定接点7dが配置された円周との間のベース3には、固定接点7e1 の外側端面と同一の回動角度の端面を持ち、反固定接点7e1 側へ延設された円弧状のリブ328 と、固定接点7e1 の固定接点7e2 側端面と同一の回動角度の端面を一端に持ち、他端に固定接点7e2 の固定接点7e1 側端面と同一の回動角度の端面を持つ円弧状のリブ329 と、固定接点7e2 の固定接点7e3 側端面と同一の回動角度の端面を一端に持ち、他端に固定接点7e3 の固定接点7e2 側端面と同一の回動角度の端面を持つ円弧状のリブ3210と、固定接点7e3 の外側端面と同一の回動角度の端面を持ち、反固定接点7e3 側へ延設された円弧状のリブ3211とを一体突設してある。
【0027】
これらリブ321 …の高さは固定接点7a1 …の高さより高く形成され、またリブ321 …の端面はアール面としており、該アール面の半径はリブ321 …の高さと略同じに設定してあって、可動接点15A,15B,15Cがリブ321…に乗り上げることにより固定接点7から開離し、リブ321 …から下りることにより固定接点7a1 …と接触する構成となっている。
【0028】
而して自動変速機用コントロールスイッチでは、シフトレバーの回動操作に応じて可動体10が一体的に回動して、可動接点15A〜15Cが夫々に対応する対の固定接点間を接触・開離することで切換出力としてポジション信号を信号系回路に出力して表示ランプ…をオン・オフしたり、スタートモータへの通電路をオン・オフ、またバックライトをオン・オフするのである。
【0029】
ところで本発明の主要な構成であるベース3は、以下の方法により製作される。まず上述の固定接点7a1 ,7a2 を図11(a)(b)に示すように夫々形成した円弧状の接点形成部24を一端に設け、他端にコネクタ端子16をリード部25を介して設けた導電板7と、固定接点7b1 ,7b2 を夫々形成した円弧状の接点形成部24を一端に設け、他端にコネクタ端子16をリード部25を介して設けた導電板7と、固定接点7e2 ,7e3 を夫々形成した円弧状の接点形成部24を一端に夫々設け、他端にコネクタ端子16をリード部25を介して夫々設けた導電板7,7とを繋ぎ部26で連結した状態で金属フープ材から打ち抜いた第1の固定接点基板部27Aを製作する。この場合導電板7の他端にはコネクタ端子16を形成し、円弧状に形成された各固定接点形成部24は導電板7が略Z状に折り曲げられて、導電板7の板面より突出している。
【0030】
同様に上述の固定接点7c1 ,7c2 ,7c3 を図12(a)(b)に示すように夫々形成した円弧状の接点形成部24を一端に夫々設け、他端にコネクタ端子16をリード部25を介して設けた夫々設けた導電板7,7,7と、固定接点7dを形成した円弧状の接点形成部24を一端に設け、他端にコネクタ端子16をリード部25を介して設けた設けた導電板7と、固定接点7e1 を形成した円弧状の接点形成部24を一端に設け、他端にコネクタ端子16をリード部25を介して設けた設けた導電板7とを繋ぎ部26で連結した状態で金属フープ材から打ち抜いた第2の固定接点基板部27Bを製作する。この場合リード部25を途中で導電板7に対して垂直に折り曲げ、またコネクタ端子16をリード部25に対して垂直に折り曲げ、該部位をクランク状に形成している。
【0031】
ここで各リード部25の幅はコネクタ端子16の幅よりも幅狭に形成され、可撓性を持たせて撓み易くしてある。このように製作された第1、第2の固定接点基板部27A,27Bは図13(a)(b)に示すように1次成形に当たり一定間隔を開けて固定接点基板部27A,27Bの導電板7が接触しないように重ね配置して1次成形の金型内に入れ1次成形を行なう。このとき固定接点基板部27Aのコネクタ端子16と、固定接点基板部27Bのコネクタ端子16とは千鳥配列となって2列に配置された状態となる。また1次成形用の金型に入れた状態で下金型28Aと上金型28Bの突き合わせて部からは図15に示すようにリード部25の一部及びコネクタ端子16が外部に突出する形となる。このとき図14に示すように下金型28Aには固定接点基板部27Aのリード部25の導電板7側基部を嵌める溝37Aを形成した凸部38を所定間隔で形成するととに該凸部38の両側には固定接点基板部27Bの導電板7側のリード部25の基部を嵌める溝37Bを形成し、上金型28Bには上記凸部38を嵌合する溝36を、また溝27Bに嵌まったリード部25を抑える凸部39を所定間隔で形成していて、コネクタ端子16部分がインサート時に変形するのを防止している。またこのような構造を取ることにより1次成形時にサイドコアを必要としないようにしてある。更にコネクタ端子16より幅狭いリード部25を抑える構成であるため、隣接するリード部25、25間にスペースが取れるため、上記凸部38の幅を広くすることができて金型強度を強めることができる。
【0032】
さて1次成形により得られた1次成形体3Aは上記繋ぎ部26を切断した後、2次成形用の金型に収められる。次に2次成形の工程について図1及び図2に基づいて説明する。まず図1(a)に示すようにサイドコア29Aを開き、上金型29Bを開いた状態で上、下金型29B、29C間に1次成形体3Aを入れ、図1(b)に示すように1次成形体3Aを下金型29Cにセットする。この時上記クランク状となったリード部25がサイドコア29Aを締める時に変形しないようにクランク部位の横片をスライドコア29D上に載置して支える。
【0033】
この状態でサイドコア29Aを図1(c)に示すよう所定位置から移動させて閉じる。このときサイドコア29Aの金型内側の面にはコネクタ端子16を挿入する挿入穴30が開口しており、サイドコア29Aを閉じる際にコネクタ端子16はこの挿入穴30内に挿入される。この挿入穴30の開口部は開口方向に拡開しており、コネクタ端子16が多少曲がっていても容易にコネクタ端子16を挿入穴30内に案内することができるようになっている。またクランク状に曲げられたリード部15を基部に持つコネクタ端子16は、該リード部15によって基部の可撓性が良くなっており、そのためサイドコア29Aが閉じられ挿入穴30に案内挿入されることにより寸法矯正が為される。また2列に配列してあるコネクタ端子16は千鳥に配列しているため1次成形体3Aから突出している部位が撓んでも重なることはない。
【0034】
以上のようにして1次成形体3Aを金型内に収納し、サイドコア29Aを上述のように閉じた後、図2(a)に示すように上金型29Bを閉じ、次にスライドコア29Dを定位置まで図2(b)に示すように移動させる。この後金型内に2次成形用の樹脂を充填して2次成形を行なう(図2(c))。この2次成形は1次成形体3Aの外側壁面を2次成形体Bで覆って2次成形体Bにより外殻を形成するとともに、コネクタ部20及び軸部5のベース側部分を形成したベース3を得るための成形であって、該2次成形終了後、図2(d)に示すように型開きを行ない、完成した図3に示すベース3を得る。
【0035】
またコネクタ部20はベース3の中心線に対して偏倚させた位置に形成され基部周囲には外鍔部22を設けた形となっているが、偏倚側の外鍔部22の裏面にはスライドコア29Dにより凹み部が所定間隔に形成され凹み部間にリブ23が形成された形となっており、これらのリブ23により外鍔部22の強度の高めて、外鍔部22の薄肉化を可能とし、成形直後の収縮によりこの外鍔部22が反るのを防ぐようにしている。
