Description

【0001】
【発明の属する技術分野】
本発明は、例えばコネクタハウジング内に収容されたセンサ等の電子部品が正規の位置に収容されているか否かを検出する際に好適なハウジング内に収容した部品の位置検出装置に関するものである
【0002】
【従来の技術】
通常、自動車等の車両には、エンジンオイル等の各種オイルが多用されているが、走行に伴い油温が上がるので油温センサにより検出するようにしている。この油温センサは、コネクタに形成した収容室内に差し込みにより収容され、コネクタと一体に車両内に係止される。
従って、油温センサは車両の安全走行に関わる部品であるから、車両への組付けに先立って、コネクタを構成するコネクタハウジング内への収容の有無は元より、正規に収容されて抜け出し不可に係止されているか否か等の収容状態を検査する必要がある。
【0003】
前記検査には、下記のような種々の検査方法がある。
最も簡便な検査方法は、目視による検査である。即ち、コネクタハウジングに油温センサを嵌合した後、作業者が直接目視で確認するものである。しかし、この検査方法は、中途嵌合などを見落とす可能性があり信頼性に欠けていた。
そこで、下記のような検査方法が採用されていた。
図10に示した検査方法は、コネクタ71を構成するコネクタハウジング72内に検査治具73を用いて油温センサ74を押し込み、検査治具73を矢印方向に駆動してコネクタハウジング72と油温センサ74の双方に押し付けるものである。
また、図11に示した検査方法は、コネクタハウジング72内に油温センサ74を収容した後、図示を省略した検査治具に設けた導通ピン75を当接させて電気的に検出するものである。
【0004】
【発明が解決しようとする課題】
しかしながら、前記従来の検査方法は、以下のような問題があった。
即ち、図10で説明した検査方法は、作業者が中途嵌合などを見落とす心配があり、信頼性に欠けていた。
また、図11で説明した検査方法は、導通ピン75が矢印方向にスライドした時の移動量により油温センサ74を検出するので、仮に油温センサ74が嵌合していない場合であっても、嵌合していると誤認することがあった。
更に、図12に示したように油温センサ74がコネクタハウジング72から飛び出している場合には、検査治具の移動に伴い導通ピン75が破損してしまうことがあった。
【0005】
本発明の目的は、上記課題に鑑みてなされたものであり、コネクタハウジング等のハウジング内に収容された部品の収容状態を確実に、且つ検査対象となる部品の破損や検査装置を構成する部材の破損等を防止するハウジング内に収容した部品の位置検査装置を提供することにある。
【0006】
【課題を解決するための手段】
本発明に係わる上記課題は、下記1)乃至2)に記載したハウジング内に収容した部品の位置検査装置により解決することができる。
1)操作レバーを操作してスイッチングブロックを駆動し、該スイッチングブロック内に設けた検出ピンをハウジング内に収容した部品に当接させることにより、前記部品の収容状態を検出するハウジング内に収容した部品の位置検出装置において、前記スイッチングブロック内に形成したガイド孔に、該ガイド孔の長手方向に移動自在に前記検出ピンを配設し、且つ該検出ピンを前記部品に弾性的に当接させるとともに、前記部品との当接位置に応じて前記検出ピンの位置を変更させる弾性部材と、前記検出ピンの一部に順次形成した第1非導通部、導通部及び第2非導通部と、前記部品との当接状態に応じた前記検出ピンの位置に基づき、前記第1非導通部、導通部又は第2非導通部のいずれかに当接する通電部材とを備え、前記通電部材が前記導通部に押圧することにより、前記通電部材と前記検出ピンとの間に通電可能な電気回路が形成されるとともに、前記通電部材が前記第1非導通部又は第2非導通部に押圧することにより、前記通電部材と前記検出ピンとの間の電気回路が遮断されることを特徴とするハウジング内に収容した部品の位置検出装置。
【0007】
前記構成のハウジング内に収容した部品の位置検出装置によれば、スイッチングブロック内に形成したガイド孔に挿入された検出ピンは弾性部材によって一方向に付勢される。また、前記検出ピンの一部には、第1非導通部、導通部及び第2非導通部が順次形成されるとともに、検出ピンの位置に応じて前記第1非導通部、導通部又は第2非導通部のいずれかに当接する通電部材とを備えている。従って、検出ピンを前記部品に当接させると、通電部材が前記第1非導通部、導通部又は第2非導通部のいずれかに当接し、部品に当接して移動量が変化する検出ピンによって、電気回路が切り換えられるので、電気信号伝達の有無により部品が正規に収容されているか否かを検出することができる。
【0008】
2)前記通電部材は、前記スイッチングブロックの外側面に設けられた導電部材を支点とする弾性部材と、前記弾性部材に付勢されて前記第1非導通部、前記導通部又は前記第2非導通部のいずれかに弾性的に押圧する導通ボールとを備えていることを特徴とする前記1)記載のハウジング内に収容した部品の位置検出装置。
前記構成によれば、通電部材の先端に弾性部材により付勢される導通ボールが検出ピンに設けた第1非導通部、導通部又は第2非導通部に弾性的に接触するので、検出ピンの移動と通電部材との接触が円滑に行われる。
【0010】
【発明の実施の形態】
以下、本発明に係るハウジング内に収容した部品の位置検出装置の一実施形態を図1乃至図9に基づいて詳細に説明する。図1は本実施形態のハウジング内に収容した部品の位置検出装置の構成を示す斜視図、図2は図1におけるコネクタの装着形態を示す斜視図、図3は図1におけるコネクタの構成を示す斜視図、図4は図1におけるコネクタ受部の内部構成を示す斜視図、図5は図1におけるスイッチブロツクの内部構造を示す一部切り欠き斜視図、図6乃至図8は図5における検出ピンの構成と位置検出作用を示すスイッチングブロックの部分断面図、図9は検出ピンによるスイッチ作用を示す模式的回路図である。
【0011】
図1に示すように本実施形態のハウジング内に収容した部品の位置検出装置(以下、単に位置検出装置と略称する)1は、図中右方に示したスイッチングブロック2と、上部に示したコネクタ3を位置決めするコネクタ受部4と、スイッチングブロック2とコネクタ受部4とを一体に固定する基板部5と、スイッチングブロック2を矢印A、B方向に往復動させる操作レバー6等により構成されている。
【0012】
前記コネクタ3のハウジング内に収容され、その収容状態を検出される検出対象の部品として、本実施形態では図3に示すように油温センサ7が収容される。
本実施形態の位置検出装置1は、先ず油温センサ7を収容したコネクタ3を図1中矢印Cに示すようにコネクタ受部4にセットする。次いで、スイッチングブロック2を矢印A方向に駆動して、後述する検出ピン8によって油温センサ7の有無、更に油温センサ7の収容状態、言い換えれば正規の位置に収容されているか否か等を検出する。
【0013】
前記スイッチングブロック2の構成は、図1に示すように合成樹脂を成形したハウジング11の上側面に電極となる金属板12がネジ13aにより固定され、該金属板の一端にはネジ13bにより電線15端部に加締られた端子14が接続されている。
また、基板部4には図1及び図4に一部を示したように一対のガイド棒16、17が固定されているが、一対のガイド棒16、17はハウジング11下部の両端を挿通している。
【0014】
前記ハウジング11と前記コネクタ受部3間の前記ガイド棒17には、バネ18が設けられている。従って、図1中矢印Aで示したようにスイッチングブロック2全体をコネクタ受部4に接近させる場合、バネ18が圧縮されてスイッチングブロック2とコネクタ受部4とのぶつかり合いを防止できる。
【0015】
また、検出後にはスイッチングブロック2全体を矢印B方向に駆動するが、バネ18の反発力によって矢印B方向への駆動を円滑に行い得るようになる。
また、ハウジング11の前端側、即ちコネクタ受部4側の側面には、カバー部材21がネジ止め等により固定されている。このカバー部材21は、後述する検出ピン8等のハウジング11からの抜け出しを防止するとともに、コネクタ受部4にセットされたコネクタ3の抜け出し防止機能を有している。
【0016】
次に、前記ハウジング11の内部構造について図5乃至図8を参照して説明する。図5に示すように前記ハウジング11内には、検出ピン8と、図1に示した2種のスイッチピン23、24が設けられている。
前記検出ピン8は、コネクタ3内に収容した油温センサ7の収容状態等を検出するものであり、図5乃至図8に示すようにハウジング11内に横方向に形成されたガイド孔25内に往復動自在に配設される。
【0017】
また、前記検出ピン8の後端側、即ち図5の右端には反発バネ26の一端が係止され、反発バネ26の他端はハウジング11に固定された外部接続端子27に弾性的に接触している。
従って、検出ピン8は外部接続端子27との接触位置を支点とした反発バネ26の反発力によって、図5の左方に常に付勢されていることになる。なお、外部接続端子27には、図示を省略しているが電線が接続されている。
【0018】
また、前記検出ピン8の先端側、即ち図5の左端には小径の接触部8aが形成され、カバー部材21に形成された小径のガイド孔28を挿通してカバー部材21の表面に突出している。
この構成によれば、検出ピン8は接触部8aの形成位置が段差になり、ガイド孔25、28の径も異なっている。従って、検出ピン8は、全体が反発バネ26により図5の左方に常に付勢されるものの、検出ピン8がカバー部材21に係止される形態になり、ガイド孔25から抜け出し不可になるとともに、この位置が定常状態における検出ピン8の定位置になる。
【0019】
前記検出ピン8は、基本的に丸棒形状であるが、一部に絶縁材を環状に被覆して形成した第1の非導通部31aと、該第1の非導通部に隣接して、前記検出ピン8の素材、例えば真鍮等の導電材の一部を露呈させて形成した導通部32と、該導通部に隣接して、前記第1の非導通部31aと同様に一部に絶縁材を環状に被覆して形成した第2の非導通部31bが形成されている。
【0020】
また、前記ハウジング11内にはガイド孔25に直交するようにして、上下方向に挿通孔33が形成されている。この挿通孔33内には、通電部材34としての押圧バネ35と、ボール係止部材36と、接触子となる導通ボール37が設けられている。また、押圧バネ35の上端は、ハウジング11の上側面に固定した金属板12に係止されている。従って、導通ボール37は押圧バネ35によって常に検出ピン8の側面に押圧される。
【0021】
図5及び図6に示すように導通ボール37は導電材で形成されているが、検出ピン8が定位置にある場合は、導通ボール37は第1の非導通部31aに接触するので検出ピン8とは非導通状態となる。即ち、金属板12から通電部材34、検出ピン8に至る通電経路は形成されず、電気回路として見ればいわゆるオフの状態になる。
なお、前記電気回路は検出ピン8の位置によって、オフからオン、又はオンからオフに変化するのであるが、この切り換え作用については、後に油温センサ7の検出作用とともに詳細に説明する。
【0022】
次に、前記コネクタ受部4の構成について説明する。
図1及び図4に示すように前記コネクタ受部4は、凹状の嵌合部41を形成した受け部材42を基板部5にネジ9により締め付け固定したものである。この受け部材42の下部には、ガイド棒16、17が挿通し、その先端は基板部5に軸受けされている。
この構成によれば、受け部材42全体は移動せず、操作レバー6の回動操作によって、図1に示したように矢印A、Bで示すようにスイッチングブロック2が受け部材42に接近したり離れたりするようになる。また、前記嵌合部41は、図1中矢印Cで示すように上部開口からコネクタ3を嵌め込み得る形状に形成され、図4に示したようにその内部にはコネクタ3の誤挿入防止と係止を行う係止突起43が設けられている。
【0023】
次に、前記コネクタ3の構成について説明する。
図3に示すように本実施形態の前記コネクタ3は、箱型のコネクタハウジング51内に2種の収容部52a、52bを形成し、一方の収容部52bに油温センサ7を収容した構成になっている。なお、油温センサ7は、ハウジング内に収容された部品に相当するものであり、例えばエンジン内のオイルの温度検出等に適用される。
【0024】
ところで、油温センサ7が収容部52b内に正規に収容されると、本来は収容部52bから抜け出し不可に係止されるのであるが、常に正確に収容されるとは限らない。例えば、中途嵌合状態で収容された場合、この収容不良を見過ごして車両にセットすると、油温検出ができなくなるだけでなく、車両走行中の振動等により抜け出す等の可能性がある。
そこで、本実施形態の位置検出装置1は、油温センサ7の収容の有無と、収容状態を検出して、検査段階で確実に不良状態のコネクタを摘出するものである。
【0025】
また、前記コネクタハウジング51の外側面には、コネクタ3を他の所定の取付け位置に係止するための係止部材54が設けられ、その先端には係止突起55が設けられている。係止部材54全体は、スリット56によって弾性を有するように形成されている。
そして、図4に示すように前記嵌合部41には、前記係止部材54を嵌合する切り込み部41aが形成され、コネクタ3を嵌合部41に嵌合する際の位置決めを行い得るようになっている。また、嵌合部41内に設けられた係止突起43は、コネクタ3が正規に嵌合された時、スリット56に差し込まれるようになっている。
従って、嵌合部41にコネクタ3を嵌合する場合、係止部材54と切り込み部41aとの位置合わせ、更に係止突起43とスリット56との位置合わせが必要であり、これらの位置合わせを行うことにより、コネクタ3の中途嵌合状態を防止することができる。
【0026】
次に、本実施形態の位置検出装置1による油温センサ7の収容状態の検査について説明する。
先ず、図1に示すように操作レバー6を引き起こし、スイッチングブロック2全体をコネクタ受け部4から離す。なお、操作レバー6は、連結ピン61によって基板部5の一端に回動自在に取り付けられ、操作レバー6とスイッチングブロック2とは連結ピン62、63及び板状の連結部材64とにより連結されている。従って、操作レバー6を引き起こし、連結ピン61を中心にして時計方向に回動することによって、スイッチングブロック2全体が矢印B方向に移動し、コネクタ受部4の上部が開放状態になり、嵌合部41全体が露出するようになる。
【0027】
この状態で、予め収容部52bに油温センサ7を収容させたコネクタ3を嵌合部41の上部から矢印C方向に嵌合する。この嵌合時に、図4に示したように係止部材54を切り込み部41aに位置合わせして、スリット56に係止突起43を差し込ませる。また、図1に想像線で示したように油温センサ7に接続された電線7aは、コネクタ受部4の背面側から引き出される。
【0028】
次に、操作レバー6を連結ピン61を中心にして反時計方向に回動させると、スイッチングブロック2全体が矢印A方向に移動し、スイッチピン24がコネクタ受部4の壁面4aに接触して、スイッチングブロック2がコネクタ受部4に接近したことを検知する(図4参照)。なお、スイッチピン23は、本実施形態ではコネクタ3に形成した収容部52a(図3参照)に差し込まれるので作動しない。
【0029】
図2に示すように操作レバー6を完全に回動させると、連結部材64が略水平になり、バネ18の反発力によってスイッチングブロック2が矢印B方向に押されても元の状態に自動復帰することはなく、カバー部材21が嵌合部41の上部を一部覆うようになる。
このようにスイッチングブロック2がコネクタ受部4に接近すると、後述するように油温センサ7の収容状態が検出される。
【0030】
図1に示した定常状態では、検出ピン8は反発バネ26により図5に示す左方に付勢され、段差部分がカバー部材21に当接して抜け出し不可になるとともに、この位置を保持する。そして、操作レバー6を回動させることによって、前記のようにスイッチングブロック2全体が矢印A方向に移動し、スイッチピン24によってコネクタ受部4への接近が検出される。
そして、図2に示すように操作レバー6を完全に回動させると、図7に示すようにスイッチングブロック2とコネクタ受部4とが接触する。この際、ガイド棒16が挿通しているバネ18は、コネクタ受部4に設けた挿通孔内に収容されるので、カバー部材21とコネクタ受部4とは完全に接触する。
【0031】
前記コネクタ受部4には、上述したようにコネクタ3が嵌め込まれ、コネクタ3には油温センサ7が予め嵌合されている。そして、正規に嵌合された場合は、油温センサ7の表面とコネクタ受部4の壁面とが、図7に示すように略面一になる。
従って、スイッチングブロック2のカバー部材21がコネクタ受部4に接触すると、検出ピン8が油温センサ7の表面に当接し、スイッチングブロック2の矢印A方向(図1参照)の動きに逆行して、しかも反発バネ26に抗して図7中右方向に付勢される。
ここで注目すべきは、通電部材34の位置は変わらず、検出ピン8のみが右方向に移動することである。故に、通電部材34を構成する導通ボール37は、図7に示すように導通部32に接触するようになり、通電部材34と検出ピン8とが通電可能になる。
【0032】
上述した状態を電気的に説明すると、図6に示すように定常状態では通電部材34の導通ボール37が検出ピン8の第1の非導通部31aに接触するので、図9に示すように端子14、金属板12、押圧バネ35、導通ボール37から検出ピン8に至る電気回路がオフになって通電不可になる。
次に、図7に示すように検出ピン8が油温センサ7に当接して図中右方向に移動すると、通電部材34の導通ボール37が検出ピン8の導通部32に接触するので、図9に示すように端子14、金属板12、押圧バネ35、導通ボール37から検出ピン8に至る電気回路がオンになって通電可能になる。
従って、外部接続端子27の先にランプ等を接続することで、油温センサ7が正規に収容されていることをランプの点灯によって視覚的に検知することができる。
【0033】
また、図8に示すように油温センサ7が収容不良でコネクタ3からはみ出している場合は、そのはみ出し量に応じて検出ピン8がスイッチングブロック2内に押し込められる。即ち、油温センサ7のはみ出し量が大きく、検出ピン8はカバー部材21の壁面と面一になるまで押し込められている。
従って、通電部材34の導通ボール37が導通部32から第2非導通部31bに接触するので、図9に示すように端子14、金属板12、押圧バネ35、導通ボール37から検出ピン8に至る電気回路がオフになって通電不可になる。よって、油温センサ7が収容不良であることをランプの不点灯によって検知することができる。
【0034】
ところで、本実施形態の位置検出装置1においては、検出ピン8と通電部材34とで形成される切り換え可能な電気回路以外に、スイッチピン24によるスイッチ回路が作用する。即ち、スイッチピン24は、上述したようにスイッチングブロック2をコネクタ受部4に接近させた時、オン状態に切り換えられるものである。
従って、検出ピン8と通電部材34とで形成される電気回路に、スイッチピン24によるスイッチ回路を直列接続した場合は、スイッチングブロック2がコネクタ受部2に接近した場合にのみ、検出ピン8と通電部材34とによる電気回路が形成されることになる。
【0035】
なお、スイッチピン24の切り換え動作と、検出ピン8と通電部材34との切り換え動作とを組み合わせることにより、より多種の検出が可能になる。例えば、スイッチピン24がオフで通電部材34が第1非導通部31aに押圧している場合、スイッチピン24がオフであるにもかかわらず検出ピン8が何らかの事情により押されて通電部材34の導通ボール37が導通部32に接触した場合、又は第2非導通部31bに接触した場合がある。
更に、スイッチピン24がオン状態に切り換えられて、しかも検出ピン8と通電部材34との切り換え動作が上述したように行われる。
このような多種の検出を行い得るので、収容状態を検出する部品としては前記油温センサ7に限定されず、各種部品についてより多種の検出を行うことができる。
【0036】
【発明の効果】
以上説明したように本発明のハウジング内に収容した部品の位置検出装置によれば、スイッチングブロック内に形成したガイド孔に、該ガイド孔の長手方向に移動自在に検出ピンを配設し、且つ該検出ピンを部品に弾性的に当接させるとともに、該部品との当接位置に応じて検出ピンの位置を変更させる弾性部材と、検出ピンの一部に順次形成した第1非導通部、導通部及び第2非導通部と、前記部品との当接状態に応じた検出ピンの位置に基づき、第1非導通部、導通部又は第2非導通部のいずれかに当接する通電部材とを備え、前記通電部材が前記導通部に押圧することにより、前記通電部材と前記検出ピンとの間に通電可能な電気回路が形成されるとともに、前記通電部材が前記第1非導通部又は第2非導通部に押圧することにより、前記通電部材と前記検出ピンとの間の電気回路が遮断される。従って、検出ピンが部品の収容状態に応じて移動することで、通電部材が第1非導通部、導通部又は第2非導通部のいずれかに当接し、部品に当接して移動量が変化する検出ピンによって、電気回路が切り換えられるので、電気信号伝達の有無により部品が正規に収容されているか否かを検出することができる。
【0037】
また、前記ハウジング内に収容した部品の位置検出装置において、前記通電部材は、スイッチングブロックの外側面に設けられた導電部材を支点とする弾性部材と、該弾性部材に付勢されて第1非導通部、導通部又は第2非導通部のいずれかに弾性的に押圧する導通ボールとを備えている。
従って、通電部材の先端に弾性部材により付勢される導通ボールが検出ピンに設けた第1非導通部、導通部又は第2非導通部に弾性的に接触するので、検出ピンの移動と通電部材との接触が円滑に行われる。

BACKGROUND OF THE INVENTION
The present invention is, for example, electronic parts such as a sensor housed in the connector housing is related to the position detecting device of the parts accommodated in the suitable housing in detecting whether or not accommodated in the normal position.
[0002]
[Prior art]
Normally, various types of oil such as engine oil are used in vehicles such as automobiles. However, since the oil temperature rises as the vehicle travels, the oil temperature sensor detects the oil temperature. The oil temperature sensor is housed by being inserted into a housing chamber formed in the connector, and is locked in the vehicle integrally with the connector.
Therefore, since the oil temperature sensor is a component related to safe driving of the vehicle, prior to assembly to the vehicle, whether or not it is accommodated in the connector housing constituting the connector is properly accommodated and cannot be pulled out. It is necessary to inspect the accommodation state such as whether or not it is locked.
[0003]
The inspection includes the following various inspection methods.
The simplest inspection method is visual inspection. That is, after the oil temperature sensor is fitted to the connector housing, the operator directly confirms it visually. However, this inspection method lacks reliability because it may miss over-fitting.
Therefore, the following inspection methods have been adopted.
In the inspection method shown in FIG. 10, the oil temperature sensor 74 is pushed into the connector housing 72 constituting the connector 71 using the inspection jig 73, and the inspection jig 73 is driven in the direction of the arrow to connect the connector housing 72 and the oil temperature. The sensor 74 is pressed against both sides.
In the inspection method shown in FIG. 11, after the oil temperature sensor 74 is accommodated in the connector housing 72, a conduction pin 75 provided on an inspection jig (not shown) is brought into contact with and electrically detected. is there.
[0004]

FIG. 9 is a schematic circuit diagram showing the switching action by the detection pin. FIG. 9 is a partial sectional view of the switching block showing the pin configuration and position detection action.
[0011]
As shown in FIG. 1, a position detection device (hereinafter simply referred to as a position detection device) 1 for components housed in a housing according to the present embodiment is shown in a switching block 2 shown on the right side of the drawing and an upper portion. A connector receiving portion 4 for positioning the connector 3, a substrate portion 5 for fixing the switching block 2 and the connector receiving portion 4 together, an operation lever 6 for reciprocating the switching block 2 in the directions of arrows A and B, and the like. ing.
[0012]
In the present embodiment, as shown in FIG. 3, an oil temperature sensor 7 is housed as a detection target component that is housed in the housing of the connector 3 and whose housing state is detected.
In the position detection device 1 of the present embodiment, first, the connector 3 housing the oil temperature sensor 7 is set in the connector receiving portion 4 as indicated by an arrow C in FIG. Next, the switching block 2 is driven in the direction of the arrow A, and the presence or absence of the oil temperature sensor 7 is detected by a detection pin 8 described later, and further, the accommodation state of the oil temperature sensor 7, in other words, whether or not the oil temperature sensor 7 is accommodated at a regular position. To detect.
[0013]
As shown in FIG. 1, the switching block 2 has a structure in which a metal plate 12 serving as an electrode is fixed to a top surface of a housing 11 formed of synthetic resin by screws 13a, and an electric wire 15 is attached to one end of the metal plate by screws 13b. A crimped terminal 14 is connected to the end.
A pair of guide rods 16 and 17 are fixed to the substrate portion 4 as shown in part in FIGS. 1 and 4. The pair of guide rods 16 and 17 are inserted through both ends of the lower portion of the housing 11. ing.
[0014]
A spring 18 is provided on the guide rod 17 between the housing 11 and the connector receiving portion 3. Accordingly, when the entire switching block 2 is moved closer to the connector receiving portion 4 as indicated by the arrow A in FIG. 1, the spring 18 is compressed and collision between the switching block 2 and the connector receiving portion 4 can be prevented.
[0015]
Further, after the detection, the entire switching block 2 is driven in the direction of the arrow B, but the driving in the direction of the arrow B can be smoothly performed by the repulsive force of the spring 18.
Further, a cover member 21 is fixed to the front end side of the housing 11, that is, the side surface on the connector receiving portion 4 side by screwing or the like. The cover member 21 has a function of preventing a connector 3 set in the connector receiving portion 4 from being pulled out while preventing a detection pin 8 and the like described later from being pulled out from the housing 11.
[0016]
Next, the internal structure of the housing 11 will be described with reference to FIGS. As shown in FIG. 5, the detection pin 8 and the two types of switch pins 23 and 24 shown in FIG.
The detection pin 8 detects an accommodation state or the like of the oil temperature sensor 7 accommodated in the connector 3, and in the guide hole 25 formed in the lateral direction in the housing 11 as shown in FIGS. It is arrange | positioned so that reciprocation is possible.
[0017]
Further, one end of a repulsion spring 26 is locked to the rear end side of the detection pin 8, that is, the right end in FIG. 5, and the other end of the repulsion spring 26 elastically contacts an external connection terminal 27 fixed to the housing 11. is doing.
Accordingly, the detection pin 8 is always urged to the left in FIG. 5 by the repulsive force of the repulsion spring 26 with the contact position with the external connection terminal 27 as a fulcrum. The external connection terminal 27 is connected to an electric wire (not shown).
[0018]
Further, a small-diameter contact portion 8a is formed at the distal end side of the detection pin 8, that is, the left end in FIG. 5, and the small-diameter guide hole 28 formed in the cover member 21 is inserted to protrude from the surface of the cover member 21. Yes.
According to this configuration, the detection pin 8 has a step at the formation position of the contact portion 8a, and the diameters of the guide holes 25 and 28 are also different. Accordingly, although the entire detection pin 8 is always urged to the left in FIG. 5 by the repulsion spring 26, the detection pin 8 is locked to the cover member 21 and cannot be pulled out from the guide hole 25. At the same time, this position becomes the fixed position of the detection pin 8 in the steady state.
[0019]
The detection pin 8 is basically in the shape of a round bar, and is adjacent to the first non-conductive portion 31a formed by partially covering an insulating material with an annular shape, and the first non-conductive portion, A conductive portion 32 formed by exposing a part of a material of the detection pin 8, for example, a conductive material such as brass, and a part of the detection pin 8 is adjacent to the conductive portion and insulated in the same manner as the first non-conductive portion 31a. A second non-conductive portion 31b formed by covering the material in an annular shape is formed.
[0020]
An insertion hole 33 is formed in the housing 11 in the vertical direction so as to be orthogonal to the guide hole 25. In the insertion hole 33, a pressing spring 35 as a current-carrying member 34, a ball locking member 36, and a conduction ball 37 as a contact are provided. The upper end of the pressing spring 35 is locked to the metal plate 12 fixed to the upper side surface of the housing 11. Therefore, the conduction ball 37 is always pressed against the side surface of the detection pin 8 by the pressing spring 35.
[0021]
As shown in FIGS. 5 and 6, the conduction ball 37 is formed of a conductive material. However, when the detection pin 8 is in a fixed position, the conduction ball 37 contacts the first non-conduction portion 31a. 8 is a non-conductive state. That is, the energization path from the metal plate 12 to the energization member 34 and the detection pin 8 is not formed, and when viewed as an electric circuit, it is in a so-called off state.
The electric circuit changes from off to on or from on to off depending on the position of the detection pin 8. This switching action will be described in detail later together with the detection action of the oil temperature sensor 7.
[0022]
Next, the configuration of the connector receiving portion 4 will be described.
As shown in FIGS. 1 and 4, the connector receiving portion 4 is obtained by fastening and fixing a receiving member 42 having a concave fitting portion 41 to the substrate portion 5 with screws 9. Guide rods 16 and 17 are inserted into the lower portion of the receiving member 42, and their tips are supported by the substrate portion 5.
According to this configuration, the entire receiving member 42 does not move, and the switching block 2 approaches the receiving member 42 as shown by arrows A and B as shown in FIG. Get away. Further, the fitting portion 41 is formed in a shape that allows the connector 3 to be fitted from the upper opening as indicated by an arrow C in FIG. 1, and as shown in FIG. A locking projection 43 for stopping is provided.
[0023]
Next, the configuration of the connector 3 will be described.
As shown in FIG. 3, the connector 3 of the present embodiment has a configuration in which two types of accommodating portions 52a and 52b are formed in a box-shaped connector housing 51, and the oil temperature sensor 7 is accommodated in one accommodating portion 52b. It has become. The oil temperature sensor 7 corresponds to a component housed in the housing, and is applied to, for example, temperature detection of oil in the engine.
[0024]
By the way, when the oil temperature sensor 7 is properly accommodated in the accommodating portion 52b, the oil temperature sensor 7 is normally locked so as not to come out of the accommodating portion 52b, but is not always accurately accommodated. For example, in the case of being accommodated in the mid-fitting state, if this accommodation failure is overlooked and set in the vehicle, not only the oil temperature can be detected, but also there is a possibility that the vehicle will come out due to vibrations during traveling of the vehicle.
Therefore, the position detection device 1 of the present embodiment detects whether or not the oil temperature sensor 7 is accommodated and the accommodation state, and reliably extracts a defective connector at the inspection stage.
[0025]
Further, a locking member 54 for locking the connector 3 to another predetermined mounting position is provided on the outer surface of the connector housing 51, and a locking projection 55 is provided at the tip thereof. The entire locking member 54 is formed to have elasticity by the slit 56.
As shown in FIG. 4, the fitting portion 41 is formed with a cut portion 41 a for fitting the locking member 54 so that positioning can be performed when the connector 3 is fitted to the fitting portion 41. It has become. Further, the locking protrusion 43 provided in the fitting portion 41 is inserted into the slit 56 when the connector 3 is properly fitted.
Therefore, when the connector 3 is fitted to the fitting portion 41, it is necessary to align the locking member 54 and the cut portion 41a, and further align the locking projection 43 and the slit 56. By doing so, an intermediate fitting state of the connector 3 can be prevented.
[0026]
Next, the inspection of the accommodation state of the oil temperature sensor 7 by the position detection device 1 of the present embodiment will be described.
First, as shown in FIG. 1, the operating lever 6 is raised to separate the entire switching block 2 from the connector receiving portion 4. The operating lever 6 is pivotally attached to one end of the substrate portion 5 by a connecting pin 61, and the operating lever 6 and the switching block 2 are connected by connecting pins 62 and 63 and a plate-like connecting member 64. Yes. Therefore, when the operating lever 6 is raised and pivoted clockwise around the connecting pin 61, the entire switching block 2 is moved in the direction of arrow B, and the upper part of the connector receiving portion 4 is opened, and is fitted. The entire portion 41 is exposed.
[0027]
In this state, the connector 3 in which the oil temperature sensor 7 is previously accommodated in the accommodating portion 52b is fitted in the arrow C direction from the upper portion of the fitting portion 41. At the time of this fitting, as shown in FIG. 4, the locking member 54 is aligned with the notch 41 a and the locking projection 43 is inserted into the slit 56. Further, as shown by the imaginary line in FIG. 1, the electric wire 7 a connected to the oil temperature sensor 7 is drawn from the back side of the connector receiving portion 4.
[0028]
Next, when the operating lever 6 is rotated counterclockwise around the connecting pin 61, the entire switching block 2 moves in the direction of arrow A, and the switch pin 24 contacts the wall surface 4a of the connector receiving portion 4. Then, it is detected that the switching block 2 has approached the connector receiving portion 4 (see FIG. 4). In this embodiment, the switch pin 23 is not operated because it is inserted into the accommodating portion 52a (see FIG. 3) formed in the connector 3.
[0029]
As shown in FIG. 2, when the operating lever 6 is completely rotated, the connecting member 64 becomes substantially horizontal, and even if the switching block 2 is pushed in the direction of arrow B by the repulsive force of the spring 18, it automatically returns to the original state. The cover member 21 partially covers the upper portion of the fitting portion 41.
When the switching block 2 approaches the connector receiving portion 4 in this way, the accommodation state of the oil temperature sensor 7 is detected as will be described later.
[0030]
In the steady state shown in FIG. 1, the detection pin 8 is urged to the left as shown in FIG. 5 by the repulsion spring 26, and the stepped portion comes into contact with the cover member 21 so that it cannot be pulled out and holds this position. Then, by rotating the operation lever 6, the entire switching block 2 moves in the direction of arrow A as described above, and the approach to the connector receiving portion 4 is detected by the switch pin 24.
When the operation lever 6 is completely rotated as shown in FIG. 2, the switching block 2 and the connector receiving portion 4 come into contact as shown in FIG. At this time, since the spring 18 through which the guide rod 16 is inserted is accommodated in the insertion hole provided in the connector receiving portion 4, the cover member 21 and the connector receiving portion 4 are completely in contact with each other.
[0031]
As described above, the connector 3 is fitted into the connector receiving portion 4, and the oil temperature sensor 7 is fitted into the connector 3 in advance. And when fitted normally, the surface of the oil temperature sensor 7 and the wall surface of the connector receiving part 4 will become substantially flush, as shown in FIG.
Therefore, when the cover member 21 of the switching block 2 comes into contact with the connector receiving portion 4, the detection pin 8 comes into contact with the surface of the oil temperature sensor 7 and goes against the movement of the switching block 2 in the direction of arrow A (see FIG. 1). Moreover, it is urged to the right in FIG. 7 against the repulsion spring 26.
It should be noted here that the position of the energizing member 34 does not change and only the detection pin 8 moves in the right direction. Therefore, the conducting ball 37 constituting the energizing member 34 comes into contact with the conducting portion 32 as shown in FIG. 7, and the energizing member 34 and the detection pin 8 can be energized.
[0032]
When the state described above is electrically explained, as shown in FIG. 6, in a steady state, the conducting ball 37 of the energizing member 34 contacts the first non-conducting portion 31a of the detection pin 8, so that the terminal as shown in FIG. 14, the electric circuit from the metal plate 12, the pressing spring 35, the conduction ball 37 to the detection pin 8 is turned off, and the current cannot be supplied.
Next, as shown in FIG. 7, when the detection pin 8 contacts the oil temperature sensor 7 and moves to the right in the figure, the conduction ball 37 of the energization member 34 contacts the conduction portion 32 of the detection pin 8. 9, the electric circuit from the terminal 14, the metal plate 12, the pressing spring 35, and the conduction ball 37 to the detection pin 8 is turned on and can be energized.
Therefore, by connecting a lamp or the like to the end of the external connection terminal 27, it is possible to visually detect that the oil temperature sensor 7 is properly accommodated by lighting the lamp.
[0033]
Further, as shown in FIG. 8, when the oil temperature sensor 7 is poorly accommodated and protrudes from the connector 3, the detection pin 8 is pushed into the switching block 2 according to the amount of protrusion. That is, the protruding amount of the oil temperature sensor 7 is large, and the detection pin 8 is pushed in until it is flush with the wall surface of the cover member 21.
Accordingly, since the conduction ball 37 of the conduction member 34 contacts the second non-conduction part 31b from the conduction part 32, the terminal 14, the metal plate 12, the pressing spring 35, and the conduction ball 37 to the detection pin 8 as shown in FIG. The electric circuit that reaches is turned off and cannot be energized. Therefore, it is possible to detect that the oil temperature sensor 7 is poorly accommodated by the lamp not lighting.
[0034]
By the way, in the position detection apparatus 1 of this embodiment, the switch circuit by the switch pin 24 acts in addition to the switchable electric circuit formed by the detection pin 8 and the energization member 34. That is, the switch pin 24 is switched to the ON state when the switching block 2 is brought close to the connector receiving portion 4 as described above.
Therefore, when the switch circuit by the switch pin 24 is connected in series to the electric circuit formed by the detection pin 8 and the energization member 34, the detection pin 8 and the switch only when the switching block 2 approaches the connector receiving portion 2. An electric circuit is formed by the energization member 34.
[0035]
Note that various types of detection can be performed by combining the switching operation of the switch pin 24 and the switching operation of the detection pin 8 and the energization member 34. For example, when the switch pin 24 is off and the energizing member 34 is pressed against the first non-conducting portion 31a, the detection pin 8 is pushed for some reason even though the switch pin 24 is off, and the energizing member 34 There is a case where the conduction ball 37 comes into contact with the conduction part 32 or a case where it comes into contact with the second non-conduction part 31b.
Further, the switch pin 24 is turned on, and the switching operation between the detection pin 8 and the energizing member 34 is performed as described above.
Since such various types of detection can be performed, the component for detecting the accommodation state is not limited to the oil temperature sensor 7, and various types of detection can be performed for various components.
[0036]
【The invention's effect】
As described above, according to the position detection apparatus for components housed in the housing of the present invention, the detection pin is disposed in the guide hole formed in the switching block so as to be movable in the longitudinal direction of the guide hole, and An elastic member that elastically abuts the detection pin to a component and changes the position of the detection pin according to the abutment position with the component; a first non-conducting portion that is sequentially formed on a part of the detection pin; A conducting member and a second non-conducting part, and a current-carrying member that abuts on either the first non-conducting part, the conducting part or the second non-conducting part based on the position of the detection pin according to the abutting state with the component When the energizing member presses against the conducting portion, an electric circuit capable of energizing is formed between the energizing member and the detection pin, and the energizing member is the first non-conducting portion or the second. By pressing against the non-conductive part, Electrical circuit between the serial conduction member and the detection pin is blocked. Therefore, by detecting pin moves in response to receiving the state of the component, the first non-conducting portion is current-carrying member, contact the one of the conductive portion or the second non-conducting portion, the movement amount in contact with the part Since the electric circuit is switched by the changing detection pin, it is possible to detect whether or not the component is properly accommodated by the presence or absence of electric signal transmission.
[0037]
Further, in the position detecting device for a component housed in the housing, the energizing member includes an elastic member having a conductive member provided on an outer surface of the switching block as a fulcrum, and the elastic member is urged by the first non-conductive member. And a conduction ball that elastically presses either the conduction part, the conduction part, or the second non-conduction part.
Accordingly, since the conducting ball urged by the elastic member at the tip of the energizing member elastically contacts the first non-conducting portion, the conducting portion or the second non-conducting portion provided on the detection pin, the detection pin is moved and energized. The contact with the member is performed smoothly.
