Description

【0001】
【発明の属する技術分野】
本発明は、ワイヤートラスタイプや方立タイプ等のカーテンウォールの壁面に取り付ける太陽電池モジュールの配線構造に関する。
【0002】
【従来の技術】
連続する太陽電池モジュールを接続する電気配線は、図8の部分図および図9の全体図に示す如く、各太陽電池モジュール100に接続する端子箱101は大きな形状で、各太陽電池モジュール100の裏面に接続してあると共にその各太陽電池モジュール100を接続する配線102が複雑に露出して室内から非常に見苦しいものとなっている。
【0003】
特に、図10に示すようなワイヤートラスタイプのカーテンウォールは内側からも美観が考慮されており、そのようなカーテンウォールの一部に太陽電池モジュールを配置する場合、一層見苦しいものとなる。そこで、近時太陽電池モジュールの端部に取り付けることができる端子が開発されて室内から大きな端子箱が見えないような構造がとれるようになった。
【0004】
【発明が解決しようとする課題】
ところが、小さい端子とはいえ、各太陽電池モジュールに取り付けると外観上目障りとなり、しかも複数の端子を接続する配線が複雑に露出することを防ぐことができず、美観が要求されるワイヤートラスタイプや方立タイプのカーテンウォールではそのような複雑な配線が室内から見える状態は大きな問題であった。
【0005】
【課題を解決するための手段】
そこで本発明は、太陽電池モジュールの一側に端子を取り付ける係止部を形成し、連続する太陽電池モジュールの目地に、上記係止部に取り付けた端子を隠す被覆金具を設けて端子を隠し、該被覆金具に形成した溝内に上記端子からの電線を引き出すと共にこの被覆金具を連結する連結管内に上記電線を導いて納めたことを特徴とする。
【0006】
【発明の実施の形態】
以下に本発明の実施の形態を図面を用いて説明する。図1は端子の接続状態を示す説明図、図2は端子の他の接続状態を示す説明図、図3は端子の接続状態を示す説明図、図4は端子の接続状態を示す説明図、図5は配線状態を示す一部破断平面図、図6は被覆金具と連結管の状態を示す断面図、図7は被覆金具の取り付け状態を示す説明図であり、図において、1は太陽電池モジュールであり、図面では太陽電池モジュールを構成する各セルの表示は省略してある。この太陽電池モジュールの一側の導電部2に係止部3を形成し、その係止部3に端子4が取り付けてある。
【0007】
この端子4の係止部3の状態は、図1に示す如く、太陽電池モジュール1の導電部2のガラス5に端子4が設置できる幅の段差部6を形成して係止部3とし、その段差部6に設置するように取り付ける。このように太陽電池モジュール1の厚さ内に端子4を納めたもので、端子4が太陽電池モジュール1表面に突出しないかわずかに突出する程度に取り付けてある。
【0008】
この端子4の係止部3の状態は、上記の構成に限るものではなく、図2に示す如く、太陽電池モジュール1の導電部2のガラス5に端子4が設置できる程度の切り欠7を形成して係止部3とし、その切り欠7内に納まるように付けて取り付けてもよい。このように上記と同様に太陽電池モジュール1の厚さ内に端子4を納め、端子4が太陽電池モジュール1表面に突出しないかわずかに突出する程度に取り付けてある。
【0009】
このように各太陽電池モジュール1に取り付けた端子4からの各配線8は、図5、図6に示す如く、被覆金具9に引き出し、その被覆金具9を連結する連結管10内に納めて導く。上記被覆金具9はどのような構造でもよいが、例えば、アルミニウム等の金属製であり、図示する如く、各太陽電池モジュール1の目地を構成する接続個所に取り付けるものであり、縦目地11を挟んだ横目地12に、反対面から当てる押し縁13によって取り付けられるもので、両側の固定部14を連結部15で連結支持しており、この連結部15に連結管10を配置し、この連結管10が縦目地11に沿うように被覆金具9は設置される。連結管10は連結部15との接続個所に導入口20を有し、さらに、その接続個所付近で各連結管が連結されているような構造としてあると作業上具合がよい。
【0010】
この被覆金具9内には、配線8を案内する溝16が形成されており、この溝16によって案内された各配線8が導入口20より連結管10内に導かれるもので、この溝16は被覆金具9の正面に形成された配線作業用の長窓21によって開放され、この長窓21はゴムや合成樹脂等による着脱可能なカバー22を嵌めることによって最終的には閉じられる。
【0011】
さらに、この被覆金具9には上記押し縁13を係止する係止部17が形成されており、上記押し縁13に形成した係止突起18が嵌入され、ボルト19で一体に固定されるようになっている。なお、図において、23はターンバックル、24は中間クランプ、25はワイヤートラスを構成するワイヤーロープである。
【0012】
以上の構成によると、太陽電池モジュール1の一側の導電部2に形成した段差部6もしくは切り欠7内に取り付けた端子4は、外観上被覆金具9と押し縁13内に納まり、端子4からの配線8はその被覆金具9内の溝16内に案内され、さらにその配線8は被覆金具9を連結する連結管10内に導入口20より納めて導かれることによって隠され、外観上見えない状態となる。
【0013】
また、連結管10は連結部15との接続個所で接続されていると、配線の接続作業や保守、点検に際しても作業上の障害は少ない。
【0014】
【発明の効果】
以上詳細に説明した本発明によると、太陽電池モジュールの一側に導電部の係止部を形成し、その係止部に端子を取り付け、連続する太陽電池モジュールの目地に取り付けた被覆金具によって上記係止部の端子を隠すと共に被覆金具に形成した溝内に上記端子からの電線を引き出し、その被覆金具を連結する連結管内に各電線を導いて納めたことにより、各端子は被覆金具によって隠され、各端子からの各配線は被覆金具内および連結管内に納められて隠されることになり、カーテンウォールの壁面等に取り付けた太陽電池モジュールが外観上良好となり、内側から見ても見苦しくないという効果を有する。
【0015】
また、各端子および各配線は目地に取り付けた被覆金具によって隠されているだけであるために、その取り付けの作業性に優れ、さらに、着脱可能なカバーによって被覆金具内の配線の保守、点検も容易となる効果を有する。
