Description

【0001】
【発明の属する技術分野】
本発明は、車両に取り付けられるブレーキオイルタンクに取り付けられるオイルレベルセンサの取付構造に関するものである。
【0002】
【従来の技術】
従来より、車両に搭載されるブレーキオイルなどのオイル残量は、オイルレベルセンサによってチェックしている。このオイルレベルセンサは、例えばリードスイッチからなる検出部を備え、オイルタンク内に磁石を配設したフロートを収容させることにより、該フロートが近づくと前記リードスイッチが通電することにより、残量を検出するものである。
【0003】
前記オイルレベルセンサをオイルタンクに取り付けるには、図5に示す取付構造が適用されている。即ち、オイルタンク1には、下部に幅方向に貫通する挿入孔2が形成されている。また、オイルレベルセンサ3には、そのケースに係止爪4aを備えた弾性を有する一対の係止片4が設けられている。そして、このオイルレベルセンサ3を前記挿入孔2に差し込むことにより、前記係止片4の爪4aが挿入孔2の開口の縁に係止することにより、取付状態を保持する。
【0004】
【発明が解決しようとする課題】
しかしながら、前記オイルレベルセンサ3の取付構造では、メンテナンス時などにオイルレベルセンサ3のケースに外力が加わると、前記爪4aの係止が解除され、オイルレベルセンサ3がオイルタンク1から離脱するという問題がある。
【0005】
そこで、本発明では、オイルタンクに装着したオイルレベルセンサの離脱を確実に防止できる取付構造を提供することを課題とする。
【0006】
【課題を解決するための手段】
前記課題を解決するため、本発明のオイルレベルセンサの取付構造は、オイルタンクに収容したオイルの量を検出するためのオイルレベルセンサの取付構造において、前記オイルタンクに、その側面から内向きに窪むセンサ収容凹部を設けるとともに、該センサ収容凹部の開口部の周囲に下方を開放した断面略逆U形状の筒状体からなる固定部を外方に突出するように設けるとともに、該固定部の両側板部の内面に外向きに窪む凹部からなる係合受部を設け、前記オイルレベルセンサを、前記開口部の周囲に当接する基板部の一面にオイルの量を検出する検出部を設けるとともに、前記基板部の他面に電気接続するために相手方コネクタを外嵌して接続するコネクタ部を設け、前記基板部の他面に前記コネクタ部と所定間隔をもって外側に位置するように係合腕部を設けるとともに、該係合腕部の先端に前記オイルタンクの係合受部に係合する係合部を外向きに突出するように設けた構成とし、前記オイルタンクにオイルレベルセンサを装着した後、前記コネクタ部に相手方コネクタを取り付けることにより、該相手方コネクタによって前記係合腕部の内側への動きを規制する一方、前記相手方コネクタを取り外した状態で、開放した前記固定部の下方から前記係合腕部を内向きに撓ませることにより前記オイルタンクからオイルレベルセンサを取り外し可能に構成している。
【0007】
前記オイルレベルセンサの取付構造によれば、前記組付状態でオイルレベルセンサの係合腕部が相手方コネクタに規制されるため、この係合腕部の係合部と、オイルタンクの係合受部との係合状態を解除できない。その結果、メンテナンス時などにオイルレベルセンサのケースに外力が加わってもオイルレベルセンサがオイルタンクから離脱することを防止できる。
【0008】
また、固定部が断面略逆U形状の筒状体からなるため、固定部の強度が増し、より確実にオイルレベルセンサの離脱を防止できる。しかも、オイルタンクにオイルを注入する時などに漏れたオイルが、オイルレベルセンサのコネクタ部内に侵入することを防止でき、コネクタ部の端子がオイルにより腐食して接続不良などの不具合が生じることを防止できる。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図面に従って説明する。
図1は、本発明の実施形態に係るオイルレベルセンサ17の取付構造を適用したオイルタンク10を示す。
【0010】
このオイルタンク10は、図1および図2(A),(B),(C)に示すように、車両に搭載するブレーキオイルを収容するもので、その上面のオイル補充用の開口にキャップ11が着脱可能に取り付けられている。このオイルタンク10には、そのロアレベルを越えた位置に内向きに窪む断面円形状のセンサ収容凹部12が設けられている。このセンサ収容凹部12には、内面に長手方向に延びるガイド溝13a,13b,13cが設けられている。
【0011】
また、前記センサ収容凹部12の開口部の周囲には、該開口部を所定間隔をもって覆うように、オイルレベルセンサ17の固定部14が外向きに突設されている。この固定部14は、下向きに開放した断面略逆U形状の筒状体からなる。この固定部14の正面側には、内向きに傾斜する斜面部15が設けられている。また、固定部14の両側板部14a,14bには、外向きに窪む凹部からなる係合受部16が設けられている。
【0012】
前記オイルレベルセンサ17は、図1および図3(A),(B),(C)に示すように、前記オイルタンク10に収容したオイルの量を検出するもので、その検出部18を樹脂製の外装体に装着したものである。前記検出部18は、従来と同様に、オイルタンク10内に磁石を配設したフロートが近づくことにより通電するリードスイッチからなる。
【0013】
前記オイルレベルセンサ17の外装体は、前記固定部14内に嵌り込み、オイルタンク10の壁面に当接する基板部19を備えている。この基板部19の一面には、略断面凹字形状に突出し、その内部に前記検出部18を配設する配設部20が突設されている。この配設部20には、一対の接続端子21が配設されている。また、この配設部20の両側および下面には、前記オイルタンク10のガイド溝13に挿入されるガイド突部22a,22b,22cが設けられている。さらに、この配設部20の根本部分には、Oリング23が装着されている。そして、前記基板部19の他面には、図示しない車両の制御部と電気接続するためのコネクタ部24が設けられている。このコネクタ部24は、前向きに開口した四角筒状をなし、その内部には、前記接続端子21に接続した一対の雄端子25が配設されている。また、コネクタ部24の両側および上部には、相手方コネクタ30を外嵌するための突部26a,26b,26c,26dが設けられている。さらに、上面の突部26c,26dの間には係止突部27が設けられている。さらにまた、基板部19の他面の両側縁には、前記コネクタ部24と所定間隔をもって位置する一対の係合腕部28が設けられている。これら係合腕部28は弾性を有し、その先端には、外向きに突出して前記係合受部16に係合する係合部29が設けられている。
【0014】
前記オイルレベルセンサ17のコネクタ部24に接続する相手方コネクタ30は、前記コネクタ部24の外側を囲繞するように外嵌させて接続するもので、その両側間の幅は一対の係合腕部28の間隔より狭いものである。この相手方コネクタ30には、前記雄端子25に係合する雌端子が配設されている。また、前記突部26a,26b,26c,26dを挿入する溝と、係止突部27に係止する係止部を備えている。
【0015】
前記オイルタンク10とオイルレベルセンサ17とを組み付けるには、まず、図4(A)に示すように、オイルレベルセンサ17のコネクタ部24に相手方コネクタ30を装着していない状態で、該オイルレベルセンサ17の配設部20をセンサ収容凹部12内に挿入する。この際、固定部14の両側にオイルレベルセンサ17の係合腕部28が当接すると、無理に圧入することにより、係合腕部28を内向きに撓ませて挿入できる。そして、係合腕部28の先端の係合部29が固定部14の前端縁を越えると、係合腕部28が弾性的に原状に復帰して係合部29が固定部14の係合受部16に係合する。
【0016】
ついで、図4(B),(C)に示すように、制御部に接続された相手方コネクタ30をオイルレベルセンサ17のコネクタ部24に外嵌装着し、オイルレベルセンサ17と制御部とを接続し、組み付けが完了する。
【0017】
前記組付状態では、オイルレベルセンサ17の係合腕部28は、相手方コネクタ30の外壁面に規制され、内向きに撓むことができない。そのため、この係合腕部28の係合部29と、オイルタンク10の係合受部16との係合状態は解除できない。その結果、メンテナンス時などにオイルレベルセンサ17のケースに外力が加わってもオイルレベルセンサ17がオイルタンク10から離脱することはない。また、オイルタンク10の固定部14は、略U字形状に形成されているため、該固定部14の強度は強く、該固定部14自体が外力により変形することもない。そのため、より確実にオイルレベルセンサ17の離脱を防止できる。しかも、固定部14によりオイルレベルセンサ17の装着部分が覆われるため、オイルタンク10にオイルを注入する時などに漏れたオイルが、コネクタ24,30内に侵入することを防止でき、これらコネクタ24,30の端子がオイルにより腐食して接続不良などの不具合が生じることを防止できる。
【0018】
一方、前記オイルタンク10からオイルレベルセンサ17を取り外す場合には、オイルレベルセンサ17のコネクタ部24から相手方コネクタ30を取り外した状態で、開放した固定部14の下方から係合腕部28を内向きに撓ませることにより、取外可能である。
【0019】
なお、本発明のオイルレベルセンサ17の取付構造は、前記実施形態の構成に限定されるものではない
【0020】
【発明の効果】
以上の説明から明らかなように、本発明のオイルレベルセンサの取付構造は、組付状態でオイルレベルセンサの係合腕部が相手方コネクタに規制されるため、この係合腕部の係合部と、オイルタンクの係合受部との係合状態を解除できない。その結果、メンテナンス時などにオイルレベルセンサのケースに外力が加わってもオイルレベルセンサがオイルタンクから離脱することを防止できる。
【0021】
また、オイルタンクの固定部を、センサ収容凹部の開口部、即ち、コネクタ部を覆う断面略逆U形状の筒状体からなるように構成しているため、固定部の強度が増し、より確実にオイルレベルセンサの離脱を防止できる。しかも、オイルタンクにオイルを注入する時などに漏れたオイルが、オイルレベルセンサのコネクタ部内に侵入することを防止でき、コネクタ部の端子がオイルにより腐食して接続不良などの不具合が生じることを防止できる。

The detection unit 18 includes a reed switch that is energized when a float having a magnet disposed in the oil tank 10 approaches as in the conventional case.
[0013]
The exterior body of the oil level sensor 17 includes a substrate portion 19 that fits into the fixed portion 14 and contacts the wall surface of the oil tank 10. On one surface of the substrate portion 19, a disposing portion 20 that protrudes in a substantially cross-sectionally concave shape and in which the detection portion 18 is disposed protrudes. A pair of connection terminals 21 are disposed in the arrangement portion 20. Further, guide protrusions 22 a, 22 b, and 22 c that are inserted into the guide groove 13 of the oil tank 10 are provided on both sides and the lower surface of the arrangement portion 20. Further, an O-ring 23 is attached to the base portion of the arrangement portion 20. On the other surface of the substrate part 19, a connector part 24 for electrical connection with a vehicle control part (not shown) is provided. The connector portion 24 has a square cylindrical shape that opens forward, and a pair of male terminals 25 connected to the connection terminals 21 are disposed therein. Further, protrusions 26a, 26b, 26c, and 26d for externally fitting the mating connector 30 are provided on both sides and an upper portion of the connector portion 24. Further, a locking protrusion 27 is provided between the protrusions 26c and 26d on the upper surface.
