【０００６】
したがって、本発明は、端子を確実に保護することができる蓄電装置の提供を目的としている。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１に係る発明は、直方体の角部に切欠部（例えば実施の形態における切欠部１５）が形成された形状をなすとともに該切欠部に端子（例えば実施の形態における端子１６）が配設された蓄電装置本体（例えば実施の形態における蓄電装置本体１８）と、該蓄電装置本体に前記切欠部を覆い前記端子を覆うように取り付けられる保護カバー（例えば実施の形態における保護カバー２０）とを具備する蓄電装置において、前記保護カバーは、前記蓄電装置本体に取り付けられた状態で該蓄電装置本体の前記切欠部に近接する三つの外面部（例えば実施の形態における上面部２２、側面部２４，２６）に対し連続的に配置される三つの外面部（例えば実施の形態における上面部３７、側面部３８，３９）を有しており、前記切欠部に、一端を前記蓄電装置本体の前記端子に接続し、他端に前記保護カバーから突出する端子（例えば実施の形態における端子２１）を有する介在部（例えば実施の形態における介在部１９）を一つのみ備え、前記保護カバーには、前記他端の端子を挿入する穴部（例えば実施の形態における穴部４０）が一箇所のみ形成されており、前記他端の端子に接続ケーブル（例えば実施の形態における接続ケーブル３０）が固定されることで前記保護カバーが前記蓄電装置本体に固定されることを特徴としている。

【００１５】
蓄電装置１１は、図２に示すように、直方体の一部に切欠部１５を形成した形状をなすとともにこの切欠部１５に端子１６および電気回路１７が配設された蓄電装置本体１８と、この蓄電装置本体１８に切欠部１５を覆うように取り付けられる保護カバー２０とを具備している。
【００１６】
具体的に、蓄電装置本体１８は、互いに平行な上面部（外面部）２２および下面部２３と、上面部２２および下面部２３に対し垂直をなしかつ互いに平行な一対の側面部（外面部）２４および側面部２５と、上面部２２、下面部２３および一対の側面部２４，２５に対し垂直をなしかつ互いに平行な一対の側面部（外面部）２６および側面部２７とを有しており、上面部２２、下面部２３、側面部２４および側面部２６の互いに近接する側の角部を上下方向の全高にわたって切り欠いた形状の切欠部１５が形成された形状をなしている。そして、蓄電装置本体１８の切欠部１５には、蓄電装置本体１８から直接外に出る端子１６と、ヒューズ、コンタクタ、電流センサおよびＥＣＵのうちの少なくともいずれか一つを含む電気回路１７とが配設されている。蓄電装置本体１８から外に出る端子１６には、金属板からなるバスバー等の介在部１９を介して端子２１が接続されており、この端子２１に接続ケーブル３０が接続されることで走行用モータ１０に給電可能とする。なお、介在部１９にコンタクタを含める場合もある。
【００１７】
ここで、電気回路１７は、切欠部１５の範囲内、つまり、上面部２２と下面部２３と側面部２４と側面部２６とを延長した範囲内に全体が配置される一方、蓄電装置本体１８から直接外に出る端子１６および介在部１９も、同じ切欠部１５の範囲内に全体が配置される。また、端子２１は、先端部が切欠部１５の範囲内から上方に突出する挿入部（突出部）２１ａとされている。なお、端子２１は、上面部２２に対し平行をなす介在部１９の台部３２上に立設されており、接続ケーブル３０が載置される台座部２１ｂと接続ケーブル３０に挿入される前記挿入部２１ａとを有していて、挿入部２１ａの外周にオネジ３３が形成されている。また、切欠部１５内には、台部３２と同一平面をなす台部３４が形成されている。
【００１８】
保護カバー２０は、蓄電装置本体１８の切欠部１５に近接する三つの外面部、具体的には上面部２２、側面部２４および側面部２６の全てに対しそれぞれ連続的に配置される上面部（外面部）３７、側面部（外面部）３８および側面部（外面部）３９の三つを有している。
【００１９】
保護カバー２０の上面部３７には、所定位置に穴部４０が形成されていて、この穴部４０に台座部２１ｂを含む端子２１を挿入可能となっている。この保護カバー２０は、穴部４０に端子２１を挿入させながら上面部３７が蓄電装置本体１８の台部３２，３４上に載置させられる。なお、この状態で、台座部２１ｂの上面は保護カバー２０の上面部３７の外側に露出し、挿入部２１ａは保護カバー２０の上面部３７から突出する。
【００２０】
接続ケーブル３０は、端子２１のうち挿入部２１ａを挿入可能かつ台座部２１ｂを挿入不可な大きさの穴部４２が形成された、穴部４０より大径のリング状のケーブル端子４３を端部に有している。保護カバー２０は、穴部４０に端子２１の挿入部２１ａおよび台座部２１ｂを挿入させつつ台部３２，３４上に載置されるとともに、蓄電装置本体１８に対し、図示は略すがボルトやクリップ等で別途締結され、あるいは嵌合部を設けて別途嵌め込まれて固定される。接続ケーブル３０は、蓄電装置本体１８に固定された状態の保護カバー２０の上面部３７から突出する端子２１の挿入部２１ａを穴部４２に挿入させつつケーブル端子４３を台座部２１ｂ上に載置させる。この状態で挿入部２１ａにナット部材４４を螺合させることにより、接続ケーブル３０のケーブル端子４３がナット部材４４および台座部２１ｂで挟持され、その結果、接続ケーブル３０が端子２１に固定された状態になるとともに、ケーブル端子４３および保護カバー２０の上面部３７がナット部材４４と台部３２とに挟持された状態になり、保護カバー２０が蓄電装置本体１８に固定される。
【００２１】
この状態で、保護カバー２０は、蓄電装置本体１８の切欠部１５に近接する上面部２２、側面部２４および側面部２６の全てに対し上面部３７、側面部３８および側面部３９が連続的に配置されて切欠部１５を覆うようになっている。つまり、上面部３７が上面部２２に対し連続的に（言い換えれば隙間無く近接して同一平面をなすように）配置され、側面部３８が側面部２４に対し連続的に（言い換えれば隙間無く近接して同一平面をなすように）配置され、側面部３９が側面部２６に対し連続的に（言い換えれば隙間無く近接して同一平面をなすように）配置されるようになっている。そして、保護カバー２０と蓄電装置本体１８とが全体として概ね直方体形状をなす。
【００２２】
蓄電装置１１は、図４に示すように、このようにして連結される蓄電装置本体１８および保護カバー２０と、保護カバー２０が取り付けられた蓄電装置本体１８を載置させる取付ベース４７と、この取付ベース４７に、保護カバー２０が取り付けられた蓄電装置本体１８を固定する左右一対の固定具４８，４９とを有している。
【００２３】
そして、車体のフロアパネル１２に形成された取付部５０に取付ベース４７がボルト止めされることになり、この取付ベース４７上に載置された、保護カバー２０が取り付けられた蓄電装置本体１８は、一対の固定具４８，４９に係止され、これら固定具４８が取付ベース４７にボルト止めされることで、フロアパネル１２に固定される。
【００２４】
ここで、一方の固定具４８は、取付ベース４７にボルト止めされた状態で、蓄電装置本体１８の上面部２２、側面部２５，２６，２７に当接してこれらを係止する上面部５２、側面部５３、側面部５４および側面部５５を有している。つまり、固定具４８は、上面部５２が上面部２２を係止し、側面部５３が側面部２５を係止し、側面部５４が側面部２６を係止し、側面部５５が側面部２７を係止する。
【００２５】
また、他方の固定具４９は、取付ベース４７にボルト止めされた状態で、蓄電装置本体１８の上面部２２、側面部２４および側面部２７と、保護カバー２０の上面部３７、側面部３８および側面部３９とに当接してこれらを係止する上面部５７、側面部５８、側面部５９および側面部６０を有している。つまり、固定具４９は、上面部５７が上面部２２および上面部３７を係止し、側面部５８が側面部２４および側面部３８を係止し、側面部５９が側面部２７を係止し、側面部６０が側面部３９を係止する。
【００２６】
以上に述べた本実施形態の蓄電装置１１によれば、蓄電装置本体１８の切欠部１５に蓄電装置本体１８から直接出る端子１６および電気回路１７を配設し、切欠部１５を保護カバー２０で覆うため、蓄電装置本体１８から直接出る端子１６を確実に保護することができて端子１６の破損による液漏れ等を防止できる上、電気回路１７も確実に保護することができる。また、介在部１９を介して外に出る端子２１は破損しても保護カバー２０を外して交換するだけで容易に修理可能となる。
【００２７】
また、切欠部１５に端子１６、介在部１９、端子２１および電気回路１７を配置することでこれらを近接させることができるため、安全性を向上させることができる上、メンテナンスの作業性を向上させることができる。なお、メンテナンスはコンタクタあるいは手動操作される遮断スイッチを切り通電していない状態で行われる。
【００２８】
しかも、保護カバー２０は、蓄電装置本体１８に取り付けられた状態で蓄電装置本体１８の切欠部１５に近接する上面部２２および側面部２４，２６に対しそれぞれ連続的に配置される上面部３７および側面部３８，３９を有するため、一つの保護カバー２０を付けるのみで蓄電装置本体１８と保護カバー２０とを合わせた全体の外観が概ね直方体形状となり整うことになる。このように保護カバー２０が取り付けられた蓄電装置本体１８は概ね直方体形状をなすため、車両搭載時の無駄なスペースを小さくすることができる。
【００２９】
加えて、接続ケーブル３０の端子２１への固定で保護カバー２０も蓄電装置本体１８に共締めで固定されることになり、固定のための部材を共用できてコストを低減できるとともに、固定のための作業も共通させて工数を削減できる。
【００３０】
さらに、接続ケーブル３０を外さなければ保護カバー２０が外れないため安全性をさらに向上させることができる。
【００３１】
加えて、固定具４８，４９および取付ベース４７で蓄電装置本体１８を取付部５０に固定すると固定具４９が保護カバー２０を係止することになるため、蓄電装置本体１８に保護カバー２０を確実に固定することができる。
【００３２】
なお、切欠部１５の位置、方向および大きさは、上記に限定されることなく、種々の変更が可能である。
また、オネジを有する凸状の挿入部を形成するのではなく、図５に示すように端子２１の台座部２１ｂにメネジ７０を形成し、ボルト７１を接続ケーブル３０のケーブル端子４３に挿通させて端子２１に螺合させるようにすれば、端子２１の保護カバー２０からの大きな突出をなくすことができる。
【００３３】
【発明の効果】
以上詳述したように、請求項１に係る発明によれば、一端を蓄電装置本体の端子に接続し、他端に保護カバーから突出する端子を有する介在部を備えるため、蓄電装置本体の端子を確実に保護することができる。また、介在部を介して外に出る端子は破損しても保護カバーを外して交換するだけで容易に修理可能となる。
【００３５】
請求項２に係る発明によれば、固定具で蓄電装置本体を取付部に固定すると固定具が保護カバーを係止することになる。よって、蓄電装置本体に保護カバーを確実に固定することができる。
