Description

【０００１】
【発明の属する技術分野】
この発明は、自動車等に用いられている配線システムの配線接続用コネクタのうち、雌雄コネクタハウジングを確実に接続するためのスライダを有するコネクタに関し、特に、雌雄コネクタの挿抜時の放電によるコネクタ接続端子の欠損や放電火花による車両火災等を防止することができるスライダ付コネクタに関する。
【０００２】
【従来の技術】
近年、社会全体の急速な電子化に伴い、例えば、従来は単なる「移動」だけを目的としていた輸送手段のうちの一つである自動車にも快適性や利便性等が求められるようになり、コンピュータによる中央制御システムの下で、カーナビゲーション装置や電子制御式サスペンション装置のような種々の電子制御部品が搭載されるようになってきた。一方、このような快適性や利便性の追求のみならず、いわゆる自動車の排気ガス問題などに端を発した世界的環境問題等に関連して自動車用機器は、必要的に機械的制御から電気的制御に移り変わるようになってきた。例えば、パワーステアリング装置の動力は、従来エンジンの回転力から得ていたが、最近では電気的に動力を発生するような電動パワーステアリング装置を搭載し、いわゆる環境に優しいクリーンな電気エネルギーをより多く利用しようとする動きが活発になったこと等でその傾向を見ることができる。このような自動車用機器の多電子化に伴い、例えば、現在自動車に使用されている最大で数ワット（Ｗ）程度の自動車用機器の電気的負荷が、近い将来５〜６キロワット（ｋＷ）にまで及ぶものとなるとされ、同時に電力供給を効率良く行わなければならないため、車輌電源電圧を現在の１４ボルト（Ｖ）から４２ボルトに昇圧しようとする動きが起こり始めている。
【０００３】
【発明が解決しようとする課題】
しかしながら、このような大電力負荷となる自動車用機器が動作中に、その機器と機器とを繋ぐワイヤハーネスのコネクタを抜いたり挿したりすると、いわゆるアーク放電が発生し、そのエネルギーでコネクタの接続端子が溶損するだけでなく、放電火花が継続して起こることにより、極端な場合、車輌火災等が発生する可能性も否定できない。この原因の一つとしては、コネクタとコネクタの接続端子同士が接触する又は非接触となる状態が長く続くということが挙げられる。特に、人手によりコネクタを挿抜するときは、コネクタ同士を嵌合又は離脱する際の状態が不安定であり、アーク放電が生じるという問題がある。
【０００４】
この発明は、このような問題点に鑑みてなされたもので、雌雄コネクタの挿抜時のアーク放電によるコネクタ接続端子の欠損や放電火花の継続による車両火災等を防止することができるスライダ付コネクタを提供することを目的とする。
【０００５】
【課題を解決するための手段】
この発明に係る第１のスライダ付コネクタは、複数の雌接続端子を内部で支持すると共に、両側壁にガイド用突起が突設された雄コネクタハウジングを備えた雄コネクタと、前記複数の雌接続端子と接続される複数の雄接続端子を内部で支持すると共に、先端側に前記雄コネクタハウジングが挿入されるコネクタ挿入方向に突出して形成された雌係合壁を有し、且つ前記雌係合壁の両側壁に前記雄コネクタハウジングのガイド用突起を前記コネクタ挿入方向に案内するガイドが形成された雌コネクタハウジングを備えた雌コネクタと、前記雌コネクタハウジングの雌係合壁の両側壁に、これら両側壁に沿って前記コネクタ挿入方向と直交する方向にスライド自在に装着され、そのスライド方向に押し込まれることにより前記雄コネクタハウジングのガイド用突起と摺接して前記ガイド用突起を雌コネクタ側に引き込む第１の傾斜壁が形成されると共に、前記スライド方向に引き抜かれることにより前記雄コネクタハウジングのガイド用突起と摺接して前記ガイド用突起を雄コネクタ側に押し出す第２の傾斜壁が形成されたカム部を有するスライダとを備えたスライダ付コネクタであって、前記スライダは、二つのスライド片を、前記コネクタ挿入方向に可撓性を有する連結部によって連結してなり、前記スライダのカム部の第１の傾斜壁は、そのスライド方向に対する傾斜角度が、前記雄コネクタと雌コネクタとの挿入時に前記雌接続端子と雄接続端子とが接触する手前で挿入力のピークに達するように設定されており、前記スライダの前記連結部には、前記スライド方向に前記スライダが完全に押し込まれたロック状態のときに前記雌コネクタハウジングに形成された係止片に引っ掛かるロック片が形成され、前記ロック片は、前記ロック状態からの前記スライダの前記スライド方向への引抜時に、前記連結部を撓ませながら前記係止片と摺接する第３の傾斜壁を有し、前記雄コネクタと雌コネクタとの引抜時に前記雌接続端子と雄接続端子とが離脱する手前で引抜力のピークに達するように設定されていることを特徴とする。
【０００６】
前記スライダのカム部の第１の傾斜壁は、前記雄コネクタと雌コネクタとの挿入時に前記雌接続端子と雄接続端子とが接触する手前で第１の角度からこれよりも小さい第２の角度へと変化するように設定されていることが望ましい。
【０００７】
この発明に係る第２のスライダ付コネクタは、複数の雌接続端子を内部で支持すると共に、両側壁にガイド用突起が突設された雄コネクタハウジングを備えた雄コネクタと、前記複数の雌接続端子と接続される複数の雄接続端子を内部で支持すると共に、先端側に前記雄コネクタハウジングが挿入されるコネクタ挿入方向に突出して形成された雌係合壁を有し、且つ前記雌係合壁の両側壁に前記雄コネクタハウジングのガイド用突起を前記コネクタ挿入方向に案内するガイドが形成された雌コネクタハウジングを備えた雌コネクタと、前記雌コネクタハウジングの雌係合壁の両側壁に、これら両側壁に沿って前記コネクタ挿入方向と直交する方向にスライド自在に装着され、そのスライド方向に押し込まれることにより前記雄コネクタハウジングのガイド用突起と摺接して前記ガイド用突起を雌コネクタ側に引き込む第１の傾斜壁が形成されると共に、前記スライド方向に引き抜かれることにより前記雄コネクタハウジングのガイド用突起と摺接して前記ガイド用突起を雄コネクタ側に押し出す第２の傾斜壁が形成されたカム部を有するスライダとを備えたスライダ付コネクタであって、前記スライダのカム部には、前記スライダをスライド方向に引き抜く際に、前記ガイド用突起の下端側に一旦当接し、前記雌接続端子と雄接続端子との離脱点を確実に越える分の前記引抜力に対する反力を発生するための前記コネクタ挿入方向の前記雄コネクタ側に窪んだ凹部が形成されていることを特徴とする。
【０００８】
この発明によれば、スライダのカム部の第１の傾斜壁のスライド方向に対する傾斜角度が、雌雄接続端子が接触する手前で挿入力のピークに達するように設定されているので、コネクタ挿入時には挿入力のピークを越えた時点で雌雄両コネクタの嵌合速度が速くなる。しかも、この速度変化は、雌雄接続端子が接触する点の手前で起こるので、雌雄接続端子同士が接触する瞬間の雌雄両コネクタの相対移動速度が速くなり、コネクタ挿入時のアーク放電が起こり難くなる。これにより、雌雄接続端子の溶損を防止することができる。
また、スライダの連結部に形成されてスライド方向への引抜時に前記連結部を撓ませながら雌コネクタハウジングの係止片と摺接するロック片に第３の傾斜壁が形成され、雌雄接続端子が離脱する手前で引抜力のピークに達するように設定されているので、コネクタ引抜時の引抜力のピークを越えた時点で雌雄両コネクタの離脱速度が速くなる。この速度変化は、雌雄接続端子が離脱する点の手前で起こるので、雌雄接続端子同士が非接触となる瞬間の雌雄両コネクタの相対移動速度が速くなり、コネクタ引抜時のアーク放電が起こり難くなる。これにより、雌雄接続端子の溶損を防止することができる。
【０００９】
【発明の実施の形態】
以下、図面を参照して、この発明の実施例を説明する。
図１は、この発明の一実施例にかかるスライダ付コネクタを斜め上側から見た斜視図、図２は雄コネクタの上面図、正面図及び側面図、図３は、雌コネクタの側面図及び背面図、図４は、スライダの上面図、正面図及び側面図である。この実施例のコネクタは、例えば中央部分の垂直方向に縦３列に大電力負荷への接続用端子を配置した雄コネクタ１及び雌コネクタ２並びに雌コネクタ２に装着されたスライダ３から構成されている。
【００１０】
雄コネクタ１は、以下のように構成されている。即ち、雄コネクタハウジング４には、コネクタ嵌合方向に延びる複数の端子収容孔５が雄コネクタハウジング４の垂直方向中央付近に縦１列で形成され、これら端子収容孔５に大電力負荷の接続用のハーネス６の先端に圧着された雌接続端子７が収容されている。雄コネクタハウジング４の下面部には、ガイド溝８が形成され、両側面の先端側中央部はガイド用突起２０が突設されている。このガイド用突起２０は、嵌合面側及び基端側方向に向かって円弧を描く円柱形状の従動部２０ａ及び２０ｂを有し、この従動部２０ａ，２０ｂが後述するスライダ３のカム部５２の第１の傾斜壁５２ａ，５２ｂ及び第２の傾斜壁５２ｃと摺接し、雄コネクタハウジング４の嵌合方向及び離脱方向に力を受ける。
【００１１】
一方、雌コネクタ２は、以下のように構成されている。即ち、先端部に雄コネクタハウジング４の先端が挿入されるコネクタ嵌合方向に突出した雌係合壁２１を形成してなる雌コネクタハウジング２２には、雄コネクタ１の雌接続端子７に対応して、大電力負荷の接続用のハーネス２３の先端に圧着された雄接続端子２４が、図３に示すように、端子収容孔３２に装着されている。雌コネクタハウジング２２には、雄コネクタハウジング４のガイド溝８及びガイド用突起２０とそれぞれ対応する位置に、これらと嵌合するガイド突条３０及びガイド溝３１がそれぞれ形成されている。雌係合壁２１の両側壁には、スライダ３を自在に装着するためのスライダ挿入口３５を有するスライダ装着部３６と、上述した雄コネクタハウジング４のガイド用突起２０を案内する、コネクタ挿入方向に延びるガイド溝３１とが形成されている。スライダ装着部３６の外壁の上部には、スリットが形成されていて、スライダ３の抜け防止片５３がこのスリットに引っ掛かるように形成されている。
【００１２】
スライダ３は、図４に示すように、左右二つのスライド片５５と、この二つのスライド片５５を連結するアーチド・トップ形状の連結部５４ａ，５４ｂとで構成されている。連結部５４ａには、例えば人差し指の爪を引っ掛けるための引掛片５６が形成されている。一方、連結部５４ｂには、第３の傾斜壁５７ａを有するロック片５７が形成されている。この連結部５４ｂは、ロック片５７の第３の傾斜壁５７ａが雌コネクタハウジング２２に形成された係止片２９の先端側と摺接するため、その摺接側方向と反対側方向へ可撓性を有する。この連結部５４を把持しながらスライダ３をスライダ装着部３６から引き抜くと、スライダ３が完全にスライダ装着部３６に挿入されたときに、スライダ３の抜けを防止するロック片５７の雌コネクタハウジング２２の係止片２９への引っ掛かりによる抜け防止ロックを解除して、スライダ３を引き抜く方向に動かすことができる。このロック片５７は、スライダ３をスライダ装着部３６に完全に挿入した場合に、雌コネクタハウジング２２の上部に形成された係止片２９の折れ内側の内壁に引っ掛かり、スライダ３がスライダ装着部３６から抜け出すのを防止すると共に、雄コネクタ１及び雌コネクタ２の嵌合状態を、ただ単に両コネクタ１，２を嵌合方向と反対の方向に引っ張るだけでは解除できなくなるようにロックする役割も果たしている。
【００１３】
また、スライド片５５は、基本的に左右対称で成形されており、左右両スライド片５５には抜け防止片５３と、カム部５２と、従動突起５９，６０とがそれぞれ２つずつ設けられている。抜け防止片５３は、図３に示すように、スライダ３のスライド片５５をスライダ装着部３６のスライダ挿入口３５にある程度の長さまで挿入したときに有効となり、スライダ装着部３６に係止してあるスライダ３がスライダ挿入口３５から抜け出してしまうのを防止する。従動突起５９，６０は、スライド片５５がスライダ装着部３６に挿入された後に、スライダ装着部３６の内壁の所定の位置にそれぞれ当接し、スライダ３の押し込み／引き抜き操作でのそれぞれの操作に対して内壁を乗り越えるときに多少の抵抗感を与え、全体としてメリハリのある操作感を実現するためのものである。
【００１４】
カム部５２は、スライド片５５を切り欠いたスリット状で、この切り欠いたスリット状のうち、雌係合壁２１の先端方向に向かってスライダ３のスライド方向に対する第１の角度をなす第１の傾斜壁５２ａ（以下、「傾斜壁５２ａ」とする。）及び第２の角度をなす第１の傾斜壁５２ｂ（以下、「傾斜壁５２ｂ」とする。）を有すると共に、後端方向に向かって第２の角度と同角度をなす第２の傾斜壁５２ｃ（以下、「傾斜壁５２ｃ」とする。）を有している。これら傾斜壁５２ａ〜５２ｃのうち、傾斜壁５２ａは、傾斜壁５２ｂよりもスライダ３のスライド方向に対する角度が大きくなるように形成され、例えば傾斜壁５２ａがなす第１の角度は３０°、傾斜壁５２ｂ，５２ｃがなす第２の角度は１０°というように設定されている。このスライダ３を用いた雄及び雌コネクタ１，２の嵌合／離脱は、図５に示すように行われる。即ち、同図（ａ）に示すように、嵌合時にはスライダ３の連結部５４ａを上から押すことで雄及び雌コネクタ１，２が嵌合を開始し、ガイド用突起２０の従動部２０ｂが傾斜壁５２ａと摺接すると、ここで反力が発生するため所定以上の押圧力でスライダ３を押さないと雄コネクタ１が動かなくなる。次に、同図（ｂ）に示すように、ガイド用突起２０の従動部２０ｂが傾斜壁５２ｂと摺接すると、スライダ方向に対する角度が傾斜壁５２ａよりも小さいため、傾斜壁５２ａと摺接していたときに蓄えられた押圧力が一気に解放される。この反動により同図（ｃ）に示すように、雄及び雌コネクタ１，２同士が速い嵌合速度で完全嵌合する。嵌合の際に、雄及び雌コネクタ１，２の雌雄接続端子同士がこの速い嵌合速度域で接触を開始するようにすれば、アーク放電を起こし難くなり、接続端子の溶損を防止し安全にコネクタの嵌合作業を行うことができる。
【００１５】
また、離脱時にはスライダ３の連結部５４ａに設けられた引掛片５６等を引っ掛けて引き上げることにより雄及び雌コネクタ１，２の離脱を行う。この離脱開始時に、傾斜壁５２ｃと従動部２０ａとが摺接し、且つ連結部５４ｂに形成されたロック片５７の第３の傾斜壁５７ａ（以下、「傾斜壁５７ａ」とする。）が雌コネクタハウジング２２に形成された係止片２９の先端側と摺接して反力が発生し、連結部５４ｂが雄コネクタ１方向に撓み、この撓みによる反力が解放されることによる反動で雄及び雌コネクタ１，２の離脱速度が確実に速くなり、傾斜壁５２ｃと従動部２０ａとが摺接することで離脱方向の引抜力を発生しながら一気に離脱する。離脱の際に、雄及び雌コネクタ１，２の雌雄接続端子同士がこの速い離脱速度域で非接触となるようにすれば、アーク放電を防止することができる。また、この反動でスライダ３が引抜方向にストロークするときに、傾斜壁５２ｂと傾斜壁５２ａとの境界点を確実に越えるようにすれば、コネクタ離脱時に発生する、いわゆるチャタリングを防ぐこともできる。これにより、安全にコネクタの離脱作業を行うことができる。
【００１６】
上記のように構成されたスライダ付コネクタによれば、雄コネクタハウジング４のガイド用突起２０の従動部２０ｂが傾斜壁５２ａと摺接しているときのスライダ３のスライド動作を第１の挿入動作とし、傾斜壁５２ｂと摺接しているときのスライド動作を第２の挿入動作とすると、図６に示すように、スライダ３の挿入開始時には、雄コネクタハウジング４に設けられたガイド用突起２０の従動部２０ｂは、スライダ３のカム部５２の傾斜壁５２ａと▲１▼で示すように摺動角度３０°で接触し、その後は傾斜壁５２ｂと▲２▼で示すように摺動角度１０°で接触する。即ち、第１の挿入動作でのスライダ３が従動部２０ｂを嵌合方向に押し込もうとする力は、第２の挿入動作での嵌合方向に押し込もうとする力よりも大きいものとなる。また、雄コネクタハウジング４のガイド用突起２０の従動部２０ａが傾斜壁５２ｃと摺接しているときのスライダ３のスライド動作を引抜動作とすると、スライダ３の引抜開始時から最後まで、雄コネクタハウジング４に設けられたガイド用突起２０の従動部２０ａは、スライダ３のカム部５２の傾斜壁５２ｃと▲２▼で示すように摺動角度１０°で接触する。また、このとき雌コネクタハウジング２２に形成された係止片２９の先端とスライダ３のロック片５７の傾斜壁５７ａとが所定の角度で接触するため上述したようにスライダ３の連結部５４ｂが撓り、その応力によりスライダ３をスライド方向に動かそうとする力が働く。即ち、引抜動作でスライダ３が従動部２０ａを嵌合方向と反対方向に引き抜こうとする力は、初期段階が一番大きいものとなる。その様子を、図７のグラフに示している。
【００１７】
即ち、このスライダ付コネクタは、実線で表される挿入力曲線▲１▼で示すように、コネクタ同士の雄及び雌接続端子が接触を開始する時点をＴ₁とすると、その時点よりも前の嵌合開始時点（Ｔ₂）では、スライダの押圧力を余計に必要とするが、カム部の傾斜壁の角度が変化する時点（Ｔ₃）で押圧力のカーブが急激に変化するため、以後慣性力でスライダ３が押し込まれる。カム部の傾斜壁の角度変化は、雌雄端子挿入力のピーク時（Ｔ₄）よりも手前で、且つ雌雄接続端子同士が接触する時点（Ｔ₁）以前であるため、Ｔ₁の時点では、コネクタ同士の嵌合速度は非常に速いものとなる。従って、雌雄接続端子同士が接触する時点（Ｔ₁）では、いわゆるアーク放電による溶損等が起こりにくくなり、且つ低挿入力でスライダ３を押し込むことができるため、大電力負荷を扱うコネクタの嵌合を安全に行うことができる。また、同図に破線で表される離脱力曲線▲２▼で示すように、コネクタ同士の雄及び雌接続端子が非接触となる時点をＴ₁とすると、その時点よりも前の離脱開始時点から引抜力のピークに達する時点（Ｔ₅）まで、直線的に強い引抜力が必要となり、Ｔ₁の時点よりも前に引抜力のピークがくる。これにより、Ｔ₁の時点では、コネクタ同士の離脱速度は上述した嵌合速度と同様に非常に速いものとなる。従って、雌雄接続端子同士が非接触となる時点（Ｔ₁）では、いわゆるチャタリング等が起こりにくくなるため、大電力負荷を扱うコネクタの離脱を安全に行うことができる。ちなみに、図８に示すように、コネクタ引抜速度と接続端子の溶損との関係は、電圧４２ボルト（Ｖ）において負荷２．８ｋＷの時の直線Ａ及び０．４ｋＷの時の直線Ｂのいずれの場合でも、引抜速度が速いほど接続端子の溶損（損傷）が少なくなるということが分かる。このことは挿入速度と接続端子の溶損との関係についてもいえることである。つまり、本発明のスライダ付コネクタを使用することで、コネクタの挿抜速度を通常のコネクタよりも確実に速くすることができるため、大電力負荷のコネクタ特有のアーク放電を防止し、接続端子の溶損が発生する可能性を少なくすることが可能となる。
【００１８】
図９は、この発明の他の実施例に係るスライダ付コネクタ及びスライダを示す側面図である。この実施例のコネクタは、雌雄コネクタについては、上述したコネクタと同様の構造を有しているが、スライダの構造が若干変更されているものである。なお、上記実施例で説明した内容と重複する部分は、説明を割愛する。スライダ１００のカム部１０２は、スライド片１０５を切り欠いたスリット状からなり、この切り欠いたスリット状のうち、嵌合方向に向かってスライダ１００のスライド方向に対する第１の角度をなす第１の傾斜壁１０２ａ（以下、「傾斜壁１０２ａ」とする。）及び第２の角度をなす第１の傾斜壁１０２ｂ（以下、「傾斜壁１０２ｂ」とする。）を有すると共に、この傾斜壁１０２ｂのスライド引抜方向側よりも嵌合方向側に窪んだ凹部１０３を有する。また、離脱方向に向かって第２の角度と同角度をなす第２の傾斜壁１０２ｃ（以下、「傾斜壁１０２ｃ」とする。）を有している。これら傾斜壁１０２ａ〜１０２ｃは、例えば傾斜壁１０２ａがなす第１の角度は３０°、傾斜壁１０２ｂ，１０２ｃがなす第２の角度は１０°というように設定されている。スライダ１００の連結部１０４ａ，１０４ｂのうち、連結部１０４ｂには、ロック片１０５が形成されると共に、このロック片１０５と雌コネクタハウジング１１０に形成された係止片（図示せず）とのロック状態を解除するための把持部１０６が形成されている。コネクタ離脱時にはスライダ１００の連結部１０４ｂに設けられた把持部１０６を摘んで引き上げることにより雄及び雌コネクタ１１１，１１２の離脱を行う。この離脱開始時に、凹部１０３とガイド用突起１２０とが当接し、且つ連結部１０４ｂに形成されたロック片１０５の第３の傾斜壁１０５ａが雌コネクタハウジング１１０に形成された係止片（図示せず）の先端側と摺接して反力が発生し、連結部１０４ｂが雄コネクタ１１１方向に撓み、この撓みによる反力が解放されることによる反動及び凹部１０３とガイド用突起１２０との当接することによる反力の発生で雄及び雌コネクタ１１１，１１２の離脱速度が確実に速くなる。従って、この速い離脱速度域で雌雄接続端子同士が非接触となるようにすれば、アーク放電を防止することができると共に、いわゆるチャタリングを防ぐこともでき、接続端子の溶損少なくし、安全にコネクタの離脱作業を行うことができる。
【００１９】
【発明の効果】
以上述べたように、この発明によれば、スライダのカム部の第１の傾斜壁のスライド方向に対する傾斜角度が、雌雄接続端子が接触する手前で挿入力のピークに達するように設定されているので、コネクタ挿入時には挿入力のピークを越えた時点で雌雄両コネクタの嵌合速度が速くなる。しかも、この速度変化は、雌雄接続端子が接触する点の手前で起こるので、雌雄接続端子同士が接触する瞬間の雌雄両コネクタの相対移動速度が速くなり、コネクタ挿入時のアーク放電が起こり難くなる。これにより、雌雄接続端子の溶損を防止することができるという効果を奏する。
また、スライダの連結部に形成されてスライド方向への引抜時に前記連結部を撓ませながら雌コネクタハウジングの係止片と摺接するロック片に第３の傾斜壁が形成され、雌雄接続端子が離脱する手前で引抜力のピークに達するように設定されているので、コネクタ引抜時の引抜力のピークを越えた時点で雌雄両コネクタの離脱速度が速くなる。この速度変化は、雌雄接続端子が離脱する点の手前で起こるので、雌雄接続端子同士が非接触となる瞬間の雌雄両コネクタの相対移動速度が速くなり、コネクタ引抜時のアーク放電が起こり難くなる。これにより、雌雄接続端子の溶損を防止することができるという効果も奏する。

In recent years, with the rapid digitization of society as a whole, for example, automobiles, which are one of the means of transportation that were only intended for `` moving '' in the past, have been required to have comfort and convenience, Various electronic control components such as a car navigation device and an electronically controlled suspension device have been mounted under a central control system by a computer. On the other hand, not only in pursuit of comfort and convenience, but also in the global environmental problems originating from the so-called automobile exhaust gas problem, automobile equipment is required from mechanical control to electrical It has come to change to the control. For example, the power of the power steering device has been obtained from the rotational force of the engine, but recently it has been equipped with an electric power steering device that generates power electrically, and more so-called environmentally friendly clean electric energy is increased. The trend can be seen as the movement to use becomes active.

However, when such an automotive device that is a large power load is in operation, if the connector of the wire harness connecting the device is disconnected or inserted, so-called arc discharge occurs, and the connection terminal of the connector is generated by the energy. In the extreme case, there is no denying the possibility of a vehicle fire or the like due to the continuous discharge sparks. One reason for this is that the connector and the connection terminals of the connector are in contact with each other or in a non-contact state for a long time.

The first inclined wall of the cam portion of the slider has a second angle smaller than the first angle before the female connection terminal and the male connection terminal come into contact with each other when the male connector and the female connector are inserted. It is desirable that it is set to change.
[0007]
A second connector with a slider according to the present invention includes a male connector provided with a male connector housing that internally supports a plurality of female connection terminals and projecting guide protrusions on both side walls, and the plurality of female connections. A plurality of male connection terminals to be connected to the terminal, and a female engagement wall formed on the distal end side so as to protrude in a connector insertion direction in which the male connector housing is inserted, and the female engagement A female connector having a female connector housing in which guides for guiding guide projections of the male connector housing in the connector insertion direction are formed on both side walls of the wall, and both side walls of the female engaging wall of the female connector housing; The male connector housing is slidably mounted along the both side walls in a direction perpendicular to the connector insertion direction, and pushed into the sliding direction. A first inclined wall is formed to slidably contact the guide protrusion of the connector and pull the guide protrusion toward the female connector side, and slidably contact the guide protrusion of the male connector housing by being pulled out in the sliding direction. A slider-attached connector comprising a slider having a cam portion formed with a second inclined wall that pushes the guide protrusion toward the male connector, and the slider is pulled out in a sliding direction on the cam portion of the slider. In this case, the connector in the insertion direction for generating a reaction force against the pulling force that is once in contact with the lower end side of the guide projection and surely exceeds the separation point between the female connection terminal and the male connection terminal. A concave portion is formed on the male connector side .
[0008]
According to the present invention, the inclination angle of the slider cam portion with respect to the sliding direction of the first inclined wall is set so as to reach the peak of the insertion force before the male and female connection terminals come into contact. When the force peak is exceeded, the mating speed of both male and female connectors increases. In addition, since this speed change occurs before the point where the male and female connection terminals come into contact with each other, the relative movement speed of the male and female connectors at the moment when the male and female connection terminals come into contact with each other increases, and arc discharge at the time of connector insertion does not easily occur. . Thereby, the melting loss of the male and female connection terminals can be prevented.
Also, a third inclined wall is formed on the locking piece formed on the connecting portion of the slider and slidingly contacting the locking piece of the female connector housing while bending the connecting portion when pulled out in the sliding direction, and the male and female connection terminals are detached. Since it is set so that the peak of the pulling force is reached before the pulling, the pulling speed of the male and female connectors increases when the peak of the pulling force at the time of pulling out the connector is exceeded. Since this speed change occurs before the point where the male and female connection terminals are detached, the relative movement speed of the male and female connectors at the moment when the male and female connection terminals are not in contact with each other is increased, and arc discharge is difficult to occur when the connectors are pulled out. . Thereby, the melting loss of the male and female connection terminals can be prevented.

Yes.
[0010]
The male connector 1 is configured as follows. That is, the male connector housing 4 is formed with a plurality of terminal receiving holes 5 extending in the connector fitting direction in a vertical line near the center of the male connector housing 4 in the vertical direction. The female connection terminal 7 crimped to the tip of the harness 6 is accommodated. A guide groove 8 is formed in the lower surface portion of the male connector housing 4, and a guide projection 20 is projected from the center on the front end side of both side surfaces. The guide protrusion 20 includes cylindrical driven portions 20a and 20b that draw an arc toward the fitting surface side and the proximal end side, and the driven portions 20a and 20b are formed on the cam portion 52 of the slider 3 described later. first inclined wall 52 a, contact 52b and the second sloped wall 5 2c sliding subjected to a force in the fitting direction and the removal direction of the male connector housing 4.
[0011]
On the other hand, the female connector 2 is configured as follows. That is, the female connector housing 22 formed with the female engaging wall 21 protruding in the connector fitting direction in which the tip of the male connector housing 4 is inserted at the tip corresponds to the female connection terminal 7 of the male connector 1. Then, the male connection terminal 24 crimped to the tip of the harness 23 for connecting a high power load is mounted in the terminal accommodation hole 32 as shown in FIG. The female connector housing 22 is formed with a guide protrusion 30 and a guide groove 31 that are fitted to the guide connector 8 and the guide projection 20 of the male connector housing 4 at positions corresponding to the guide connector 8 and the guide protrusion 20, respectively. A connector insertion direction for guiding the slider mounting portion 36 having a slider insertion port 35 for freely mounting the slider 3 and the guide protrusions 20 of the male connector housing 4 described above on both side walls of the female engagement wall 21. A guide groove 31 extending in the direction is formed. A slit is formed in the upper part of the outer wall of the slider mounting portion 36, and a slip-off preventing piece 53 of the slider 3 is formed so as to be caught by this slit.
[0012]
As shown in FIG. 4, the slider 3 includes two left and right slide pieces 55 and arched top-shaped connecting portions 54 a and 54 b that connect the two slide pieces 55. For example, a hooking piece 56 for hooking a nail of an index finger is formed in the connecting portion 54a. On the other hand, a locking piece 57 having a third inclined wall 57a is formed in the connecting portion 54b. Since the third inclined wall 57a of the locking piece 57 is in sliding contact with the distal end side of the locking piece 29 formed on the female connector housing 22, the connecting portion 54b is flexible in the direction opposite to the sliding contact direction. Have When the slider 3 is pulled out from the slider mounting portion 36 while gripping the connecting portion 54, the female connector housing 22 of the lock piece 57 that prevents the slider 3 from coming off when the slider 3 is completely inserted into the slider mounting portion 36. It is possible to move the slider 3 in the direction in which the slider 3 is pulled out by releasing the lock for preventing the locking by the hooking to the locking piece 29. When the slider 3 is completely inserted into the slider mounting portion 36, the lock piece 57 is caught on the inner wall of the engagement piece 29 formed on the upper portion of the female connector housing 22, and the slider 3 is moved to the slider mounting portion 36. And also prevents the male connector 1 and the female connector 2 from being pulled out of place, and locks the mating state of the male connector 1 and the female connector 2 so that the male connector 1 and the female connector 2 cannot be released simply by pulling the connectors 1 and 2 in the direction opposite to the mating direction. Yes.
[0013]
The slide piece 55 is basically formed symmetrically. The left and right slide pieces 55 are each provided with a slip prevention piece 53, a cam portion 52, and two driven protrusions 59 and 60. Yes. As shown in FIG. 3, the removal preventing piece 53 is effective when the slide piece 55 of the slider 3 is inserted up to a certain length into the slider insertion port 35 of the slider mounting portion 36, and is locked to the slider mounting portion 36. A certain slider 3 is prevented from coming out of the slider insertion opening 35. The driven protrusions 59 and 60 abut against predetermined positions on the inner wall of the slider mounting portion 36 after the slide piece 55 is inserted into the slider mounting portion 36, respectively. giving feel some resistance can and get over the inner wall Te, it is for realizing the operation sense of sharp overall.
[0014]
The cam portion 52 has a slit shape in which the slide piece 55 is cut out. Of the cut-out slit shape, the cam portion 52 forms a first angle with respect to the sliding direction of the slider 3 toward the distal end direction of the female engagement wall 21. The inclined wall 52a (hereinafter referred to as "inclined wall 52a") and the first inclined wall 52b (hereinafter referred to as "inclined wall 52b") having a second angle, and toward the rear end. And a second inclined wall 52c (hereinafter referred to as “inclined wall 52c”) having the same angle as the second angle. Among these inclined walls 52a to 52c, the inclined wall 52a is formed so that the angle with respect to the sliding direction of the slider 3 is larger than that of the inclined wall 52b. For example, the first angle formed by the inclined wall 52a is 30 °. The second angle formed by 52b and 52c is set to 10 °. The male / female connectors 1 and 2 are engaged / disengaged using the slider 3 as shown in FIG. That is, as shown in FIG. 5A, when the mating is performed, the connecting portion 54a of the slider 3 is pushed from above to start the mating of the male and female connectors 1 and 2, and the driven portion 20b of the guide projection 20 is moved. When the sliding contact with the inclined wall 52a occurs, a reaction force is generated here, and the male connector 1 cannot move unless the slider 3 is pressed with a predetermined pressing force. Next, as shown in FIG. 5B, when the driven portion 20b of the guide projection 20 is in sliding contact with the inclined wall 52b, the angle with respect to the slider direction is smaller than that of the inclined wall 52a. The pressing force stored at that time is released at once. Due to this reaction, the male and female connectors 1 and 2 are completely fitted at a fast fitting speed, as shown in FIG. If the male and female connection terminals of the male and female connectors 1 and 2 are started to contact at this fast fitting speed range when mating, it is difficult for arc discharge to occur and the melting of the connection terminals is prevented. The connector can be safely fitted.
[0015]
Also performs the separation of the male and female connectors 1 and 2 by pulling the catching piece 56 provided on the connecting portion 54a of the slider 3 or the like over Tsu pull during withdrawal. At the start of detachment, the inclined wall 52c and the driven portion 20a are in sliding contact with each other, and a third inclined wall 57a (hereinafter referred to as “inclined wall 57a”) of the lock piece 57 formed on the connecting portion 54b is a female connector. A reaction force is generated in sliding contact with the distal end side of the locking piece 29 formed in the housing 22, the connecting portion 54 b is bent in the direction of the male connector 1, and the reaction force due to the release of the reaction force due to this bending releases the male and female. The disconnection speed of the connectors 1 and 2 is reliably increased, and the inclined wall 52c and the driven portion 20a are in sliding contact with each other while generating a pulling force in the disconnection direction. If the male and female connection terminals of the male and female connectors 1 and 2 are brought into non-contact with each other in this fast separation speed region at the time of separation, arc discharge can be prevented. Further, when the slider 3 strokes in the pulling direction by this reaction, so-called chattering that occurs when the connector is detached can be prevented if the boundary point between the inclined wall 52b and the inclined wall 52a is surely exceeded. As a result, the connector can be safely detached.
[0016]
According to the slider-equipped connector configured as described above, the sliding operation of the slider 3 when the driven portion 20b of the guide projection 20 of the male connector housing 4 is in sliding contact with the inclined wall 52a is defined as a first insertion operation. Assuming that the sliding operation when in sliding contact with the inclined wall 52b is the second insertion operation, the guide protrusion 20 provided on the male connector housing 4 is driven at the start of the insertion of the slider 3, as shown in FIG. The portion 20b contacts the inclined wall 52a of the cam portion 52 of the slider 3 at a sliding angle of 30 ° as indicated by (1), and thereafter, the inclined wall 52b and the sliding angle of 10 ° as indicated by (2). Contact. That is, the force that the slider 3 in the first insertion operation tries to push the driven portion 20b in the fitting direction is larger than the force that pushes the driven portion 20b in the fitting direction in the second insertion operation. Become. If the sliding operation of the slider 3 when the driven portion 20a of the guide projection 20 of the male connector housing 4 is in sliding contact with the inclined wall 52c is a pulling operation, the male connector housing is from the start of pulling out of the slider 3 to the end. 4 is in contact with the inclined wall 52c of the cam portion 52 of the slider 3 at a sliding angle of 10 °, as indicated by (2). At this time, since the tip of the locking piece 29 formed on the female connector housing 22 and the inclined wall 57a of the locking piece 57 of the slider 3 contact at a predetermined angle, the connecting portion 54b of the slider 3 is bent as described above. Accordingly, a force is exerted to move the slider 3 in the sliding direction due to the stress. That is, the force at which the slider 3 pulls the driven portion 20a in the direction opposite to the fitting direction in the pulling operation is the largest in the initial stage. This is shown in the graph of FIG.
[0017]
In other words, as shown by the insertion force curve (1) represented by the solid line, this slider-equipped connector is defined as T ₁ when the male and female connection terminals of the connectors start to contact each other. At the start of mating (T ₂ ), an extra pressing force of the slider is required, but the curve of the pressing force changes abruptly when the angle of the inclined wall of the cam portion changes (T ₃ ). The slider 3 is pushed in by inertia. Change in angle inclined wall of the cam portion, at the peak of the male and female terminal insertion force before in than (T _4), and for male and female connecting terminals to each other is to point (T ₁₎ before contacting, at the time of T _1, The mating speed between the connectors is very fast. Therefore, when the male and female connection terminals come into contact with each other (T ₁ ), melting damage due to so-called arc discharge hardly occurs and the slider 3 can be pushed in with a low insertion force. Can be done safely. Further, as shown by the withdrawal force curve ▲ 2 ▼ represented by broken lines in the figure, when the time of male and female connection terminals of the connectors are out of contact with the T _1, detachment start earlier than that time point From the time point until the peak of the pulling force (T ₅ ), a strong pulling force is required linearly, and the peak of the pulling force comes before the point of T ₁ . Thus, at the time of T _1, the desorption rate of the connectors becomes very fast similarly to the fitting rate described above. Therefore, at the time (T ₁ ) when the male and female connection terminals are not in contact with each other, so-called chattering or the like hardly occurs, so that the connector for handling a high power load can be safely detached. Incidentally, as shown in FIG. 8, the relationship between the connector pull-out speed and the melting loss of the connection terminal is either a straight line A when the load is 2.8 kW or a straight line B when the load is 2.8 kW at a voltage of 42 volts (V). Even in this case, it can be seen that the faster the drawing speed, the less the melting (damage) of the connection terminal. This is also true for the relationship between the insertion speed and the melting loss of the connection terminals. In other words, by using the slider connector of the present invention, the connector insertion / removal speed can be reliably increased as compared with a normal connector, so that arc discharge peculiar to a connector of a high power load can be prevented and the connection terminal can be melted. It is possible to reduce the possibility of loss.
[0018]
FIG. 9 is a side view showing a connector with a slider and a slider according to another embodiment of the present invention. The connector of this embodiment has the same structure as the connector described above with respect to the male and female connectors, but the structure of the slider is slightly changed. In addition, the description which overlaps with the content demonstrated in the said Example is omitted. The cam portion 102 of the slider 100 has a slit shape in which the slide piece 105 is cut out. Of the cut-out slit shape, a first angle that forms a first angle with respect to the slide direction of the slider 100 toward the fitting direction. It has an inclined wall 102a (hereinafter referred to as "inclined wall 102a") and a first inclined wall 102b (hereinafter referred to as "inclined wall 102b") having a second angle, and a slide of the inclined wall 102b. It has the recessed part 103 dented in the fitting direction side rather than the drawing direction side. Moreover, it has the 2nd inclination wall 102c (henceforth "inclination wall 102c") which makes the same angle as a 2nd angle toward a detachment | leave direction. The inclined walls 102a to 102c are set such that, for example, the first angle formed by the inclined wall 102a is 30 °, and the second angle formed by the inclined walls 102b and 102c is 10 °. Of the connecting portions 104 a and 104 b of the slider 100, the connecting portion 104 b is formed with a lock piece 105 and a lock between the lock piece 105 and a locking piece (not shown) formed on the female connector housing 110. A grip portion 106 for releasing the state is formed. When the connector is detached, the male and female connectors 111 and 112 are detached by gripping and pulling up the grip portion 106 provided on the connecting portion 104b of the slider 100. At the start of the detachment, the recess 103 and the guide projection 120 are in contact with each other, and the third inclined wall 105a of the lock piece 105 formed on the connecting portion 104b is a locking piece (not shown) formed on the female connector housing 110. The connecting portion 104b bends in the direction of the male connector 111, the reaction force due to the release of the reaction force caused by this bending, and the contact between the recess 103 and the guide protrusion 120. The generation of the reaction force due to the above surely increases the detachment speed of the male and female connectors 111 and 112. Therefore, if the male and female connection terminals are not in contact with each other in this fast detachment speed region, arc discharge can be prevented, and so-called chattering can be prevented, and the melting loss of the connection terminals is reduced. The connector can be detached.
[0019]
【The invention's effect】
As described above, according to the present invention, the inclination angle of the cam portion of the slider with respect to the sliding direction of the first inclined wall is set to reach the peak of the insertion force before the male and female connection terminals come into contact. Therefore, when the connector is inserted, the fitting speed of the male and female connectors is increased when the peak of the insertion force is exceeded. In addition, since this speed change occurs before the point where the male and female connection terminals come into contact with each other, the relative movement speed of the male and female connectors at the moment when the male and female connection terminals come into contact with each other increases, and arc discharge at the time of connector insertion does not easily occur. . Thereby, there exists an effect that the melting loss of a male and female connection terminal can be prevented.
Also, a third inclined wall is formed on the locking piece formed on the connecting portion of the slider and slidingly contacting the locking piece of the female connector housing while bending the connecting portion when pulled out in the sliding direction, and the male and female connection terminals are detached. Since it is set so that the peak of the pulling force is reached before the pulling, the pulling speed of the male and female connectors increases when the peak of the pulling force at the time of pulling out the connector is exceeded. Since this speed change occurs before the point where the male and female connection terminals are detached, the relative movement speed of the male and female connectors at the moment when the male and female connection terminals are not in contact with each other is increased, and arc discharge is difficult to occur when the connectors are pulled out. . Thereby, the effect that melting of the male and female connection terminals can be prevented is also achieved.
