Description

【０００１】
【発明の属する技術分野】
本発明は、灯体を基体に被着して取り付ける標識灯に関する。
【０００２】
【従来の技術】
従来、例えば、特開平６−１０８４２７号公報に記載されているように、空港の滑走路や誘導路などの路面に埋め込み設置される埋込形の標識灯が知られている。
【０００３】
この種の標識灯は、路面に埋め込まれる略円筒状で有底の基台、およびこの基台に着脱可能に被着して取り付けられる灯体を備えている。この灯体には、ランプ、このランプから出射される光線を反射する反射鏡、フィルタ、およびレンズとなどを備えた光学系などが収納されている。
【０００４】
この灯体のランプに電力を供給するために、灯体から引き出されたリード線の先端のプラグが、基台内に導入された電源線の先端のレセプタクルに接続され、これらリード線、プラグ、電源線およびレセプタクルなどが基台内の灯体の下側に確保された空間に収納されている。
【０００５】
【発明が解決しようとする課題】
しかしながら、灯体を設置する際、灯体から引き出されたリード線のプラグと基台内に導入された電源線のレセプタクルとを接続し、これらリード線などの配線が基台と灯体との間に挟み込まないように基台の内側に押し込みながら、灯体を基台に被着して取り付ける必要があり、設置作業が煩雑になる問題を有している。
【０００６】
また、今日においては、舗装の形態によって標識灯の埋め込み深さが制限され、基台の薄型化が求められている場合があるが、基台を薄型化すると、灯体の下側に配線などを収納する空間が確保されず、薄型化が制限される問題を有している。
【０００７】
本発明は、このような点に鑑みなされたもので、設置作業を容易にできるとともに基台を含めて薄型化でき、しかも、灯体側と基台側との電気的接続を確実にできる標識灯を提供することを目的とする。
【０００８】
【課題を解決するための手段】
請求項１記載の標識灯は、円筒状の周面部および基台底面部を有し、周面部の内周には環状の段部が形成されている基台と；基台の段部に嵌合するフランジ部およびこのフランジ部の内周部から基台の段部の内側を挿通して基台底面部側に位置する灯体底面部を有し、この灯体底面部よりもフランジ部側の位置に端子台取付部が設けられており、基台に被着して基台底面部と端子台取付部との間に端子台収納凹部を形成するように取り付けられる灯体と；基台の端子台収納凹部に対応する基台底面部に設けられた給電端子を有する給電端子台と；灯体の端子台取付部に配置され、灯体の被着時に給電端子台の給電端子に電気的に接続される受電端子を有する受電端子台と；基台の段部および灯体のフランジ部にそれぞれ設けられ、基台に被着する灯体の被着方向を受電端子と給電端子との接続に際して位置決めガイドする灯体ガイド手段と；を具備しているものである。
【０００９】
そして、灯体を基台に被着することにより、基台の基台底面部との間に端子台収納凹部を形成する灯体の端子台取付部に配置した受電端子台の受電端子が、基台の端子台収納凹部に対応する基台底面部に設けられた給電端子台の給電端子に接触して電気的に接続するので、特別な配線作業が必要なく、設置作業が容易になるとともに、灯体と基台との間に配線などを収納する空間を確保する必要がなく、基台を含めて標識灯の薄型化が可能になる。さらに、基台の段部および灯体のフランジ部にそれぞれ設けられた灯体ガイド手段により、基台に被着する灯体の被着方向を受電端子と給電端子との接続に際して位置決めガイドするので、受電端子と給電端子とを確実に接続できる。
【００１０】
請求項２記載の標識灯は、請求項１記載の標識灯において、灯体ガイド手段は、ガイドピンおよび係合孔が基台の段部および灯体のフランジ部のいずれか一方にそれぞれ設けられて構成されているものである。
【００１１】
そして、受電端子と給電端子との接続が確実になる。
【００１２】
請求項３記載の標識灯は、円筒状の周面部および基台底面部を有し、周面部の内周には環状の段部が形成されている基台と；上部灯体および灯体カバーを有し、基台の段部に嵌合するフランジ部およびこのフランジ部の内周部から基台の段部の内側を挿通して基台底面部側に位置する灯体底面部を有し、この灯体底面部よりもフランジ部側の位置に端子台取付部が設けられており、灯体カバー側から基台に被着して基台底面部と端子台取付部との間に端子台収納凹部を形成するように取り付けられる灯体と；基台の端子台収納凹部に対応する基台底面部に設けられた給電端子を有する給電端子台と；灯体の灯体カバーの端子台取付部に配置され、灯体の被着時に給電端子台の給電端子に電気的に接続される受電端子を有する受電端子台と；基台の段部および灯体のフランジ部にそれぞれ設けられ、基台に被着する灯体の被着方向を受電端子と給電端子との接続に際して位置決めガイドする灯体ガイド手段と；を具備しているものである。
【００１３】
そして、灯体を基台に被着することにより、基台の基台底面部との間に端子台収納凹部を形成する灯体の灯体カバーの端子台取付部に配置した受電端子台の受電端子が、基台の端子台収納凹部に対応する基台底面部に設けられた給電端子台の給電端子に接触して電気的に接続するので、特別な配線作業が必要なく、設置作業が容易になるとともに、灯体と基台との間に配線などを収納する空間を確保する必要がなく、基台を含めて標識灯の薄型化が可能になる。さらに、基台の段部および灯体のフランジ部にそれぞれ設けられた灯体ガイド手段により、基台に被着する灯体の被着方向を受電端子と給電端子との接続に際して位置決めガイドするので、受電端子と給電端子とを確実に接続できる。
【００１４】
請求項４記載の標識灯は、請求項３記載の標識灯において、灯体ガイド手段は、ガイドピンおよび係合孔が基台の段部および灯体のフランジ部のいずれか一方にそれぞれ設けられて構成されているものである。
【００１５】
そして、受電端子と給電端子との接続が確実になる。
【００１６】
請求項５記載の標識灯は、請求項１または３記載の標識灯において、受電端子台と給電端子台との互いの組合せ方向を受電端子と給電端子との接続に際して位置決めガイドする端子台ガイド手段を具備しているものである。
【００１７】
そして、端子台ガイド手段により受電端子台と給電端子台との互いの組合せ方向を受電端子と給電端子との接続に際して位置決めガイドすることで、受電端子台と給電端子台とが確実に組み合い、受電端子と給電端子との接続が確実になる。
【００１８】
請求項６記載の標識灯は、請求項１ないし５いずれか一記載の標識灯において、給電端子台は、灯体の被着方向に対して交差する方向に移動可能に配置されているものである。
【００１９】
そして、給電端子台を灯体の被着方向に対して交差する方向に移動可能に配置したので、受電端子と給電端子との被着方向の位置にずれがあっても、受電端子を給電端子に確実に接続できる。
【００２０】
請求項７記載の標識灯は、請求６記載の標識灯において、給電端子台の可動範囲は、灯体と基台との取付公差、灯体側の受電端子台の配置公差、基台側の給電端子台の配置公差の合計値より大きいものである。
【００２１】
そして、給電端子台の可動範囲を、灯体と基台との取付公差、灯体側の受電端子台の配置公差、基台側の給電端子台の配置公差の合計値より大きく設定するので、受電端子と給電端子との被着方向の位置ずれに確実に対応できる。
【００２２】
請求項８記載の標識灯は、請求項１ないし７いずれか一記載の標識灯において、給電端子台を基台に対して灯体の被着方向と交差する方向に移動可能に保持する保持手段と；給電端子台と基台および保持手段との間に介在される低摩擦体と；を具備しているものである。
【００２３】
そして、保持手段により給電端子台を基台に対して灯体の被着方向と交差する方向に移動可能に保持し、給電端子台と基台および保持手段との間に低摩擦体を介在させたことで、受電端子台と給電端子台との被着方向の位置ずれに対応して給電端子台の移動が円滑になる。
【００２４】
請求項９記載の標識灯は、請求項１ないし８いずれか一記載の標識灯において、受電端子台は、灯体の被着時に給電端子台の給電端子に弾性的に接触されて電気的に接続される板状の受電端子を有するものである。
【００２５】
そして、板状の受電端子が、板状の給電端子に弾性的に接触することにより、受電端子台と給電端子台との被着方向の位置ずれを許容し、受電端子と給電端子との接続が確実になる。
【００２６】

【００２９】
そして、基台12は、例えばアルミニウム合金などの鋳物などにて形成され、円筒状の周面部21およびこの周面部21の底面に底面部22を有し、内側に上面を開口した灯体収納部23が形成されている。周面部21の内周には環状の段部24が突出形成され、この段部24の上側に凹状の灯体嵌合部25が形成され、段部24の下側に凹状の配線収納部26が形成されている。段部24の上面には、灯体13の取付用の複数のボルト27が立設されている。
【００３０】

【００３１】
灯体本体31は、例えばアルミニウム合金などの鋳物製の上部灯体41、およびこの上部灯体41の下側を覆う例えばアルミニウム合金などの鋳物製の下部灯体である灯体カバー42を備え、これら上部灯体41および灯体カバー42の周縁部が基台12の灯体嵌合部25に被着嵌合され、その際に上部灯体41および灯体カバー42の周縁部を貫通されて上方に突出する各ボルト27に図示しない各ナットを螺着することにより、基台12に液密に取り付けられている。灯体本体31の上部灯体41と灯体カバー42との間には液密に密閉される部品収納空間43が形成され、この部品収納空間43の内側は区画壁部44によって２個の分室45に区画されている。
【００３２】
上部灯体41の上面には、上面中央が上方に突出する略平面状の上面部48が形成され、この上面部48の周囲から上部灯体41の周縁部に向けて下降傾斜する傾斜面49が形成され、この傾斜面49に基台12の各ボルト27が挿通される複数の取付孔50が形成され、これら各取付孔50の上側にボルト27に螺合される図示しないナットが収納される凹状のナット収納部51が形成されている。
【００３３】
上部灯体41の下面には、各分室45に対応して、互いに反対側に向かうレンズ収納部54、およびこのレンズ収納部54に隣接するランプ収納空間55が形成されている。各レンズ収納部54は、それぞれ下方に向かって部品収納空間43内に突出し、上部灯体41の外側に連通する窓孔56が形成されている。
【００３４】
各レンズ収納部54の窓孔56には、それぞれ光学系を構成する略角柱状をなすブロック状のレンズ57が収納されている。さらに、各レンズ収納部54の内側を覆うようにしてレンズホルダ58が取り付けられている。このレンズホルダ58は、レンズ57の周縁部を押える枠状のレンズ押え部59と、このレンズ押え部59の下端部から折曲されてレンズ収納部54の下側に沿って配置される取付部60とを備えており、取付部60がねじ61でレンズ収納部54の下面に固定されている。
【００３５】
また、灯体カバー42は、周縁に基台12の灯体嵌合部25に嵌合する環状のフランジ部71を有し、このフランジ部71の内周部から基台12の段部24の内側に挿通される円筒状の周面部72が形成されているとともに、周面部72の底面に底面部73が形成されている。フランジ部71には、基台12の各ボルト27が挿通される複数の取付孔74が形成されている。底面部73には、各分室45に対応して、略中央にランプ取付部75が形成されているとともに、上部灯体41のレンズ収納部54とは反対側に位置して底面部73より上方に突出する端子台取付部76が形成され、この端子台取付部76に取付孔77が形成され、端子台取付部76の下側に端子台収納凹部78が形成されている。底面部73には、ランプ32の位置、ねじ61の位置、およびランプ取付部75の位置に対応して、上面に逃げ凹部79を形成して下面側に突出する突出部80がそれぞれ形成され、これら突出部80の下面は曲面に形成されている。
【００３６】
灯体カバー42の底面部73の各ランプ取付部75上には、図示しないランプホルダを介して、上部灯体41の各レンズ57に光学的に対向して、光学系を構成するミラー（反射鏡）81を一体に備えたランプ（反射鏡一体ランプ）32が傾斜状に取り付けられている。このランプ32の口金には、ランプソケット82が接続され、このランプソケット82からは、先端にコネクタ83を有するリード線84が引き出されている。
【００３７】
また、基台12と灯体13との間には、基台12に被着する灯体13の被着方向を位置決めガイドする灯体ガイド手段86が設けられている。この灯体ガイド手段86は、基台12の段部24の上面で円周方向の対称位置にそれぞれ立設された複数の灯体ガイド体87、灯体13の周縁部下面で各灯体ガイド体87の位置に対応して開口形成された灯体カバー42の係合孔88および上部灯体41の係合孔89を有している。各灯体ガイド体87は、円柱状のガイドピン（丸形ピン）であり、先端（上端）が円錐状に形成され、一方の灯体ガイド体87の直径が大きく他方の灯体ガイド体87の直径が小さく、径が異なるように構成されている。各係合孔88，89は、各灯体ガイド体87に対応してそれぞれ挿入係合可能とする内径に形成されている。
【００３８】
また、灯体13には受電端子台91が設置され、基台12には給電端子台92が設置され、これら受電端子台91と給電端子台92との接続で灯体13側と基台12側とが電気的に接続される。
【００３９】
受電端子台91は、図４に示すように、受電端子台本体101、および一対の受電端子102を有し、受電端子台本体101が灯体カバー42の端子台取付部76の下面に取り付けられ、受電端子102が灯体13を基台12に被着する被着方向すなわち下方に臨んで突出されている。
【００４０】
受電端子台本体101は、絶縁性を有する例えば樹脂製で、端子台取付部76の取付孔77に下面側から嵌合される本体部103が形成され、この本体部103の周囲からフランジ部104が突出形成され、本体部103の下面に一対の円錐状の突部105が並列に突出形成されている。フランジ部104の両端には、図示しないねじで端子台取付部76に取り付けるための取付孔106が形成されている。
【００４１】
各受電端子102は、板状のプラグ刃であり、各突部105から下方に突出されている。各受電端子102の上部には本体部103の上方に突出するランプ給電端子107が接続されている。これらランプ給電端子107は、板状のプラグ刃であり、ランプソケット82から引き出されたリード線84のコネクタ83が接続されている。
【００４２】
また、給電端子台92は、図５に示すように、給電端子台本体111およびこの給電端子台本体111内に収納された一対の給電端子112を有し、給電端子台本体111が基台12の底面部22上に配置され、この給電端子台本体111に対して灯体13の被着方向すなわち上方から差し込まれる受電端子台91の各受電端子102が各給電端子112に接続される。
【００４３】
給電端子台本体111は、絶縁性を有する例えば樹脂製で、基台12の底面部22上に配置される本体部113が形成され、この本体部113の内側には給電端子112を収納する端子収納部114が形成され、本体部113の両側にフランジ部115が突設されているとともに端子収納部114に連通する配線引出孔116が形成され、本体部113の上面に一対の突部117が突出形成され、この突部117に上方に開口する一対の断面略長方形状の差込孔118が並列に形成され、これら各差込孔118の開口端に上方へ向けて拡開する導入孔119が形成されている。
【００４４】
各フランジ部115には取付孔120が形成され、この取付孔120を挿通するねじ121で基台12の底面部22上に給電端子台92が取り付けられている。ねじ121は、ねじ軸122および頭部123を有し、ねじ軸122には取付孔120より大径でフランジ部115の上面に接合する円板状の座金124が挿通されている。ねじ軸122の直径に対して取付孔120の内径が大きく、ねじ121による取付状態においても灯体13の被着方向に対して交差する方向すなわち底面部22に沿って水平方向に移動可能としており、そして、給電端子台92の可動範囲は、灯体13と基台12との取付公差、灯体13側の受電端子台91の配置公差、基台12側の給電端子台92の配置公差の合計値より大きく設定されている。これらねじ121および座金124によって、給電端子台92を基台12に対して灯体13の被着方向と交差する方向に移動可能に保持する保持手段125が構成されている。
【００４５】
各給電端子112は、差込孔118の底部側に配置される基板部126、およびこの基板部126から折曲されて差込孔118内に側方から進入して受電端子102の側面に弾性的に接合する接触片部（プラグ刃受）127を有している。各給電端子112の基板部126には配線接続部128が接続され、これら各配線接続部128に給電端子台本体111の各配線引出孔116を通じて側方に引き出される配線131が接続されている。
【００４６】
また、図２に示すように、各給電端子台92の両側から引き出された配線131は、基台12の配線収納部26に沿って配線され、基台12の周面部21を液密に貫通した状態に取り付けられた基台端子台132の内端部に接続されている。基台端子台132の外端部には外部から電力を供給する電源線が接続される。
【００４７】
そして、標識灯11を設置するには、路面の標識灯11の設置場所に基台12の直径より内径の大きい埋込孔（ボーリング孔）をあけ、また、標識灯11への電力供給のために、滑走路や誘導路の外側に設置されるトランスの設置位置から標識灯11の設置位置つまり埋込孔までの路面に切り込みを入れて溝を形成し、この溝内に電力供給用の電源線を配線し、この電源線を埋込孔に引き込む。埋込孔に引き込んだ電源線を基台12の基台端子台132に接続し、基台12を埋込孔内に設置し、それら基台12の外周面と埋込孔の内周面との間隙に樹脂やコンクリートなどの充填材を充填して基台12を路面に埋め込み、この基台12に灯体13を上方から被着して取り付ける。
【００４８】
灯体13を基台12に上方から被着して取り付けるには、灯体13の周縁部の各係合孔88，89を基台12から突出する各灯体ガイド体87に位置合わせするとともに、灯体13の周縁部の各取付孔50，74を基台12から突出する各ボルト27の位置に合わせることで、灯体13と基台12とを互いに位置決めする。このとき、灯体13の各係合孔88，89の内径と基台12の各灯体ガイド体87の直径とが対応するもの同士を一致させ、灯体13の向きを基台12に合わせる。灯体13の各係合孔88，89を基台12の各灯体ガイド体87に挿通させるとともに、灯体13の各取付孔50，74を基台12の各ボルト27に挿通させながら、灯体13の周縁部を基台12の灯体嵌合部25に被着嵌合し、灯体13を貫通して各ナット収納部51に突出する各ボルト27の先端に各ナットを螺着することにより、基台12に液密に取り付ける。
【００４９】
灯体13を基台12に被着する際、灯体12の被着方向が灯体ガイド手段86の灯体ガイド体87と係合孔88，89との係合によってガイドされた状態で、図６に示すように、灯体13に配置された受電端子台91の受電端子102が基台12に配置された給電端子台92の差込孔118に差し込まれ、差込孔118に差し込まれた受電端子102の側面に給電端子台92の接触片部127が接触し、灯体13側の受電端子102と基台12側の給電端子112とが電気的に接続する。
【００５０】
このように、灯体13を基台12に被着することにより、灯体13に配置した受電端子台91の受電端子102が基台12に配置した給電端子台92の給電端子112に接触して電気的に接続できるので、特別な配線作業が必要なく、設置作業を容易にできるとともに、灯体13の底面と基台12との間に配線などを収納する空間を確保する必要がなく、基台12を含めて標識灯11を薄型化できる。
【００５１】
しかも、灯体ガイド手段86により基台12に被着する灯体13の被着方向を受電端子102と給電端子112との接続に際して位置決めガイドするので、受電端子102と給電端子112とを確実に接続できる。
【００５２】
また、給電端子台92は基台12上で被着方向に対して交差する方向に移動可能に取り付けることにより、受電端子102と給電端子112との被着方向の位置にずれがあっても、受電端子102の先端部が給電端子台92の導入孔119内に係合すれば、受電端子102の位置に応じて給電端子台92が移動し、受電端子102を給電端子112に確実に接続できる。そして、このときの給電端子台91の可動範囲を、灯体13と基台12との取付公差、灯体13側の受電端子台91の配置公差、基台12側の給電端子台92の配置公差の合計値より大きく設定することにより、受電端子102と給電端子112との被着方向の位置ずれに確実に対応できる。
【００５３】
なお、灯体ガイド手段86の灯体ガイド体87を灯体13に設けるとともに、係合孔を基台12側に設けても、同様の作用効果を奏する。
【００５４】
また、灯体ガイド体87は、丸形ピンに限らず、図７に示すように、断面略正方形状の角形ピンとすることにより、基台12の１箇所に設けるだけで、基台12に対する灯体13の被着方向を位置決めガイドできる。また、断面略長方形、三角形など異形状であれば、同様の作用効果を奏する。
【００５５】
また、灯体ガイド体87は、灯体カバー42の係合孔88および上部灯体41の係合孔89の両方に係合したが、図８に示すように、灯体カバー42の係合孔88にのみ係合するようにしてもよく、受電端子台91は灯体カバー42に配置されているので、少なくとも灯体カバー42を基台12に位置決めガイドするようにすれば、受電端子102と給電端子112とを確実に接続できる。
【００５６】
また、受電端子台91は灯体カバー42の底面部73より上方に突出する端子台取付部76に取り付けられるので、この受電端子台91のランプ給電端子107を底面部73より高い位置に配置でき、このランプ給電端子107に対してランプソケット82から引き出されたリード線84の先端のコネクタ83を容易に接続できる。
【００５７】
次に、図９ないし図１４に他の実施の形態を示し、図９は標識灯の断面図、図１０は標識灯の灯体の上部灯体を外した状態の平面図、図１１は標識灯の受電端子台を示し、(a)は側面図、(b)は正面図、(c)は平面図であり、図１２は標識灯の給電端子台を示し、(a)は側面図、(b)は正面図、(c)は平面図であり、図１３は標識灯の受電端子台および給電端子台を示し、(a)は接続過程の側面図、(b)は接続状態の側面図であり、図１４は標識灯の給電端子台の取付状態を示す一部を切り欠いた側面図である。なお、図１ないし図８に示した実施の形態と同様の構成、作用および効果は同一符号を用いてその説明を省略する。
【００５８】
この実施の形態では、図１ないし図８に示した実施の形態の灯体ガイド手段86に代えて、受電端子台91および給電端子台92自体に、受電端子台91と給電端子台92との互いの組合せ方向を受電端子102と給電端子112との接続に際して位置決めガイドする端子台ガイド手段151を備えている。
【００５９】
図１１に示すように、受電端子台91には、端子台ガイド手段151を構成する複数、本実施の形態では一対のガイドピン152を有し、これらガイドピン152は、受電端子台本体101のフランジ部104から上方へ立ち上げられた立上部153の下面に、一対の受電端子102と並列でかつ平行に下方へ向けて突設されている。各ガイドピン152は、円柱状で、先端が球面状に形成されており、受電端子102の先端より下方に突出されている。受電端子台本体101の下面には各受電端子102が突出する周囲部分に給電端子台92の突部117が進入する凹部154が形成されている。
【００６０】
図１２に示すように、給電端子台92には、端子台ガイド手段151を構成する複数、本実施の形態では一対のガイド孔155を有し、これらガイド孔155は、給電端子台本体111の本体部113に、各差込孔118と並列でかつ平行で上方へ向けて開口形成されている。各ガイド孔155は、給電端子台本体111の本体部113の上面に差込孔118の各突部117と並列に突設された各ガイド突部156の内側に円筒状に形成され、上端開口には上方へ向けて開口する導入孔157が形成されている。ガイド突部156は、差込孔118が開口する突部117より給電端子台本体111の上方に突出されている。また、両側のフランジ部115は、厚みを有し、給電端子112の配線接続部128に接続される配線131が引き出される配線引出孔116が形成されている。
【００６１】
そして、灯体13を基台12に被着する際、受電端子台91と給電端子台92とが互いに組み合わされて電気的に接続される。このとき、図１３に示すように、まず、受電端子台91の各ガイドピン152が給電端子台92のガイド孔155の導入孔157内に進入し、各ガイドピン152が導入孔157を通じて各ガイド孔155に進入される。そのため、受電端子台91と給電端子台92との組合せ方向に位置ずれが生じていても、その受電端子台91と給電端子台92との組合せ方向が一致するように修正できる。各ガイドピン152が各ガイド孔155に進入して受電端子台91と給電端子台92との組合せ方向が一致した状態で、受電端子102が差込孔118に確実に差し込まれ、受電端子102と給電端子112とが電気的に接続される。
【００６２】
このように、端子台ガイド手段151により受電端子台91と給電端子台92との互いの組合せ方向を受電端子102と給電端子112との接続に際して位置決めガイドするので、受電端子台91と給電端子台92とを確実に組み合わせ、受電端子102と給電端子112とを確実に接続できる。
【００６３】
また、ガイドピン152の先端が球面状であるため、ガイド孔155内に円滑に進入できるとともに、円錐状に設ける場合に比べて、突出量が少なくでき、薄型化に貢献できる。
【００６４】
また、受電端子102とは別にガイドピン152を備えることにより、受電端子102には導電性に優れた材料、ガイドピン152には強度に優れた材料の選択ができる。
【００６５】
また、受電端子台91の立上部153にガイドピン152を設け、給電端子台92のガイド孔155の上端（導入孔157）を差込孔118の上端より上方に突出させることにより、受電端子102と給電端子112との接続前にガイドピン152とガイド孔155とを係合させることができる。
【００６６】
なお、ガイドピン152は、少なくとも２本備えることにより、受電端子台91と給電端子台92とを位置決めできるが、３本以上備えていてもよい。
【００６７】
また、図１４に示すように、給電端子台92と基台12の底面部22との間に低摩擦体161を介在させるとともに、給電端子台92の上面と座金124との間に低摩擦体162を介在させることにより、給電端子台92を基台12に対して容易に移動でき、受電端子台91と給電端子台92との組合せ方向の位置ずれに対応できる。低摩擦体161，162としては、例えばフッ素樹脂加工を施したテフロンシートなどが用いられる。
【００６８】
ねじ121のねじ軸122はスリーブ165に挿通され、ねじ軸122を給電端子台92を通じて基台12の底面部22に形成されたねじ孔166に螺合して締め付けた際に、スリーブ165で底面部22と座金124との間隔が一定寸法以上狭まるのを規制し、給電端子台92を強く締め付けないことで、給電端子台92を基台12に対して容易に移動させることができる。
【００６９】
次に、図１５ないし図１９にさらに他の実施の形態を示し、図１５は標識灯の断面図、図１６は標識灯の灯体の上部灯体を外した状態の平面図、図１７は標識灯の受電端子台を示し、(a)は側面図、(b)は正面図、(c)は平面図であり、図１８は標識灯の給電端子台を示し、(a)は側面図、(b)は正面図、(c)は平面図であり、図１９は標識灯の受電端子台および給電端子台の接続状態の側面図である。なお、図１ないし図８に示した実施の形態、図９ないし図１４に示した実施の形態と同様の構成、作用および効果は同一符号を用いてその説明を省略する。

【００７１】
受電端子台本体101は、絶縁性を有する例えば樹脂製で、端子台取付部76の取付孔77に下面側から嵌合される本体部103が形成され、この本体部103の周囲からフランジ部104が突出形成され、本体部103の下面に突部105が突出形成されている。フランジ部104の両端には、図示しないねじで端子台取付部76に取り付けるための取付孔106が形成されている。
【００７２】
受電端子台本体101のフランジ部104から例えば４５°の角度で斜め上方に傾斜部171が突出形成され、突部105の下面から傾斜部171の下面にかけて各受電端子102を取り付ける一対の端子取付部172が形成されている。各端子取付部172には、突部105の下面に端子嵌合凹部173が形成され、傾斜部171の下面先端にスリット状の溝部174が形成され、傾斜部171の下面中間部に円形のばね取付凹部175が形成されている。

【００７４】
また、給電端子台92は、図１８に示すように、給電端子台本体111およびこの給電端子台本体111内に取り付けられた一対の板状の給電端子112を有し、給電端子台本体111が基台12の底面部22上に配置され、この給電端子台本体111に対して灯体13の被着方向すなわち上方から受電端子台91の各受電端子102が各給電端子112に接触して接続される。
【００７５】
給電端子台本体111は、絶縁性を有する例えば樹脂製で、基台12の底面部22上に配置される本体部113が形成され、この本体部113の内側には各給電端子112が並列に収納される端子収納部114が形成され、本体部113の両側にフランジ部115が突設されているとともに端子収納部114に連通する配線引出孔116が形成されている。本体部113の上面には例えば４５°の角度で傾斜する傾斜面181が形成され、この傾斜面181に端子収納部114に収納された各給電端子112が臨む一対の開口部182が並列に形成されている。各開口部182の横幅は、受電端子102の横幅より広く、受電端子102の進入が可能になっている。
【００７６】
各フランジ部115には取付孔120が形成され、この取付孔120を通じてねじ（ねじ121）を基台12の底面部22に螺着することにより、給電端子台92が基台12に取り付けられている。
【００７７】
各給電端子112は、板状に形成され、各開口部182の内側に配置されており、開口部182を通じて露出される平面状の接触面185を有し、この接触面185が例えば４５°の角度で傾斜されている。各給電端子112には配線接続部128が接続され、これら各配線接続部128に給電端子台本体111の各配線引出孔116を通じて側方に引き出される配線131が接続されている。
【００７８】
開口部182から臨む給電端子112の接触面185の面積は、受電端子102の接触面177の実質接触面積より大きく設定されている。
【００７９】
そして、灯体13を基台12に被着する際、受電端子台91と給電端子台92とが互いに組み合わされて電気的に接続される。このとき、図１９に示すように、受電端子102の凸湾曲状の接触面177が開口部182内に進入し、開口部182の内側に配置された給電端子112の接触面185に接触する。
【００８０】
受電端子102の一端は受電端子台本体101に固定されているが他端は受電端子台本体101の溝部174内に係合されているだけなので、受電端子102のばね性により、凸湾曲状の接触面177が給電端子112の接触面185に弾性的に接触する。さらに、コイルばね178で受電端子102の接触面177を裏側から押圧し、接触面177を給電端子112に圧接させる。そのため、受電端子102と給電端子112との接触圧力が高く、電気的接続を確実にできる。
【００８１】
このように、灯体13を被着する被着方向に臨ませた板状の受電端子102の接触面177が、板状の給電端子112の接触面185に弾性的に接触する構造とし、さらに、給電端子112の接触面185の面積を受電端子102の接触面177の実質接触面積より大きく設定する構造とすることにより、受電端子台91と給電端子台92との被着方向の位置ずれを許容でき、受電端子102と給電端子112とを確実に接続できる。
【００８２】
また、受電端子102の接触面177の向き、および給電端子112の接触面185の向きを傾斜状にすることで、それらの向きを灯体13の被着方向すなわち上下方向に合わせる場合に比べて、薄型化できる。
