【0001】
【発明の属する技術分野】
本発明は、電気自動車用の複数個のバッテリを直列に接続させるバッテリ接続プレートにおける電圧検出用の端子に電線を接続すると共に、端子の中間部をヒューズ接続のために切断するバッテリ接続プレートの端子加工装置及び端子加工方法に関するものである。
【0002】
【従来の技術】
図13は、電気自動車用のバッテリに従来のバッテリ接続プレートを組み付ける状態を示すものである。
【0003】
バッテリ81は複数個が並列に接合され、各バッテリ81の前後の電極82が正極と負極で、且つ隣接するバッテリ81の電極82が交互に正極と負極になるように配列されている。両端のバッテリ81の電極82は正極と負極になっている。電極82は雄ねじ端子で構成され、バッテリ接続プレート83はナット85で電極82に接続固定される。
【0004】
バッテリ接続プレート83は各バッテリ81を直列に接続するためにバッテリ組立体84の前後に一対組み付けられる。バッテリ接続プレート83は、合成樹脂製のプレート本体86と、プレート本体86の溝部87,88に組み込まれた矩形状のバスバー89,90と、プレート本体86にヒンジ91で開閉自在な合成樹脂製のカバー92とを備えている。
【0005】
両側の正方形のバスバー89は一つの電極挿通孔93を有し、中間部の複数の長方形のバスバー90は二つの電極挿通孔93を有している。電極挿通孔93と同心にプレート本体86の底側に大きめの電極挿通孔94が設けられている。バスバー89,90は溝部87,88に嵌め込まれて、図示しない係止爪で係止されている。カバー92は係止枠部95でプレート本体86の係合突起(図示せず)に係止される。
【0006】
図14は、本出願人が先に特願平11−136959号で提案したバッテリ接続プレートを示すものである。
【0007】
このバッテリ接続プレート97は、合成樹脂製のプレート本体98に矩形状のバスバー99と電圧検出用の電線圧着端子(以下単に端子という)100とをインサート成形により配置固定したものである。バスバー99は各バッテリ(図示せず)を直列に接続するためのものであり、端子100は各バッテリごとに電圧を検出するためのものである。端子100はバスバー99に重ねて接触させた状態でインサート成形される。
【0008】
端子100は、バスバー99に接触する略正方形で板状の接触板部101と、接触板部101から略クランク状に屈曲して延びる中間連結部102と、中間連結部102に続く電線圧着部103とで構成されている。接触板部101の中央には電極挿通孔104が設けられている。中間連結部102は中央が細幅に形成され、前後の太幅の部分にヒューズ接続用の小さな孔105が設けられている。電線圧着部103は各一対の導体圧着片106と被覆圧着片107とで構成されている。
【0009】
端子100のインサート成形後に、中間連結部102の細幅部108がカッタ(図示せず)で切断除去され、前後の太幅部分の孔105にヒューズ(図示せず)がハンダ接続される。
【0010】
プレート本体98には、接触板部101を露出させる環状部109と、中間連結部102を露出させる矩形状の枠部110と、電線圧着部103を露出させる矩形状の枠部111とが形成されている。接触板部101の周端部と中間連結部102の前後の基板部112,113とがプレート本体98内に埋入されている。プレート本体98にはヒンジ114を介してカバー115が一体に設けられている。
【0011】
【発明が解決しようとする課題】
しかしながら、上記従来のバッテリ接続プレート97にあっては、端子100の中間連結部102の細幅部108を作業者が鋏等の設備で手作業で切断しなければならず、生産性が悪いと共に、切断が不正確になりやすいという問題があった。すなわち、一枚のバッテリ接続プレート97には、バッテリの数に対応した複数の端子100がインサート成形されているために、端子100の細幅部108を鋏等で一つづつ切断する作業は大変面倒であり、非効率的であると共に、作業者の手元が狂って細幅部108を大きく切断し過ぎて、ヒューズの接続性が悪くなるといった懸念があった。
【0012】
本発明は、上記した点に鑑み、ヒューズを接続するための端子の中間連結部を効率的に且つ確実に切断することのできるバッテリ接続プレートの端子加工装置及び端子加工方法を提供することを目的とする。
【0013】
【課題を解決するための手段】
上記目的を達成するために、本発明は、複数のバッテリを直列に接続するためのバスバーと、該バッテリに接続する接触板部と電線圧着部との間に中間連結部を有する電圧検出用の端子とを合成樹脂製のプレート本体にインサート成形して成るバッテリ接続プレートの端子加工装置であって、該バッテリ接続プレートを固定する支持台と、中間連結部をヒューズ接続のために切断する切断ポンチと、電線圧着部に対するクリンパと、該切断ポンチと該クリンパとを固定する昇降自在なラムと、該切断ポンチに対するポンチ受けと、該クリンパに対するアンビルと、該支持台を複数の該端子の並び方向に移動させる移動手段とを備えることを特徴とするバッテリ接続プレートの端子加工装置を採用する(請求項1)。
前記ポンチ受けが前記中間連結部の凹部に係合することも有効である(請求項)。また、前記切断ポンチが、前記中間連結部に対する端子係合溝を有し、該端子係合溝の前後端が切断用のエッジであることも有効である(請求項)。また、前記切断ポンチが先端側に、前記ポンチ受けに対する挿入用のテーパガイド面を有することも有効である(請求項)。
また、前記ポンチ受けがポンチ挿入溝内に幅広な切断カス逃がし部を有することも有効である(請求項)。また、前記ポンチ挿入溝の底面が、切断カスを排出するための傾斜面となっていることも有効である(請求項)。
また、請求項1記載のバッテリ接続プレートの端子加工装置を用いたバッテリ接続プレートの端子加工方法であって、前記ラムの下降動作で、前記クリンパと前記アンビルで前記端子の前記電線圧着部に電線を圧着すると同時に、前記切断ポンチと前記ポンチ受けで該端子の前記中間連結部をヒューズ接続のために切断し、一つの該端子の圧着と切断を行った後、該バッテリ接続プレートを支持した前記支持台を前記移動手段で端子の並び方向に移動させて、次の端子の加工を行うことを特徴とするバッテリ接続プレートの端子加工方法を併せて採用する(請求項)。
前記ポンチ受けを前記中間連結部の凹部に係合させることも有効である(請求項)。また、前記端子の切断カスを前記ポンチ受けの傾斜面に沿って排出させることも有効である(請求項9)。
【0014】
【発明の実施の形態】
以下に本発明の実施の形態の具体例を図面を用いて詳細に説明する。
図1〜図2は、本発明の加工装置で使用するバッテリ接続プレートの一実施形態を示すものである。このバッテリ接続プレートは従来例の図14で示したものとほぼ同様のものである。
【0015】
バッテリ接続プレート1には、合成樹脂製のプレート本体2に、バッテリ接続用の矩形状で平板状のバスバー4と、正方形の接触板部5を有する電圧検出用の端子6とが重合接触した状態でインサート成形されている。バスバー4はバッテリ接続プレート1の両端側においてはなくても構わない。
【0016】
接触板部5から同一平面上に幅狭な前側基板部7が水平に突出形成され、前側基板部7から立上げ部8(図2)が垂直に屈曲形成され、立上げ部8から前側接続部9が水平に且つ短く突出形成され、前側接続部9から細幅な切断部10が一体に続き、切断部10に後側接続部11が短く続き、後側接続部11に立下げ部(後側立上げ部)12(図2)が垂直に続き、立下げ部12から後側基板部13(図2)が水平に続き、後側基板部13に電線圧着部14が続いている。
【0017】
前側基板部7と立上げ部8と前側接続部9と後側接続部11と立下げ部12とは同一の幅で形成されている。前側接続部9と後側接続部11とにはヒューズ接続用の孔17が設けられている。各接続部9,11と切断部10とは同一平面上に位置している。立下げ部12は立上げ部8よりも短く形成され、接触板部5と切断部10との高さ方向中間部に電線圧着部14が位置している。電線圧着部14は前側の一対の導体圧着片15と後側の一対の被覆圧着片16とで構成されている。各基板部7,13と立上げ部8と立下げ部12と各接続部9,11と切断部10とで中間連結部18が構成されている。
【0018】
各端子6の前側基板部7の後寄りの部分と後側基板部13の中間部分とがプレート本体2の矩形状の各枠状部19,20,22,23内にインサート成形により埋入されている。長方形のバスバー4を固定した枠状部22には、前側基板部7の前部と、接触板部5の前後と一側の三辺の周端とが埋入され、両端側の枠状部19には接触板部5の前側と両側の三辺の周端が埋入されている。
【0019】
端子6のその他の部分、すなわち接触板部5の大部分と立上げ部8と前側接続部9と切断部10と後側接続部11と立下げ部12とはプレート本体2の内側で露出されている。バスバー4と接触板部5とは同一径の電極挿通孔を有している。図2の如く、接触板部5は前側の枠状部19内で下端部寄りに位置し、各接続部9,11と切断部10とは中間の枠状部20内で上端部寄りに位置し、電線圧着部14は後側の枠状部21内で高さ方向ほぼ中間部に位置している。枠状部22〜24においても同様である。各枠状部19〜24は上下に貫通した空間を有している。
【0020】
プレート本体2の前側の枠状部19,22と中間の枠状部20,23と後側の枠状部21,24とは端子6の長手方向に一体的に続いている。前側の枠状部22と中間の枠状部23とは基板部25で連結され、基板部25上に端子6の前側基板部7が露出して位置している。端子毎に枠状部分19〜21,22〜24が分離して形成され、後側の各枠状部21,24は直交方向の樋状の電線挿通溝26の前壁27に続いている。各枠状部分19〜21,22〜24は独立して撓み移動自在で、バッテリ(図示せず)の電極に対する位置ずれ吸収作用を有している。前壁27及び後壁28には電線挿通用のスリット29,30が形成されている。後側のスリット30は端子6に電線を圧着する際に使用される。前側の枠状部22は部分的にヒンジ31を介して図示しないカバーに続いている。
【0021】
図3〜図11は、上記バッテリ接続プレート1に対する端子加工装置及び端子加工方法を示すものである。
【0022】
図3において、33は端子圧着兼端子切断用のアプリケータ、1はバッテリ接続プレートを示す。アプリケータ33は、横L字状のフレームとフレームに垂直方向スライド自在に係合したラム35と、ラム35に一体的に固定された端子圧着用のクリンパ36及び端子切断用の切断ポンチ39と、クリンパ36に対向してフレームの基台40に設けられたアンビル41と、基台40に立設されたポンチ受け44と、バッテリ接続プレート1をセットする昇降自在な支持45とを備えている。
【0023】
ラム35の上部にはシャンク46が設けられ、シャンク46は図示しないシリンダやモータといった駆動部を用いた昇降部分に連結される。ラム35は正面側のガイド板47に沿って昇降自在である。ラム35の正面側にクリンパ36が固定され、ラム35の中心寄りに切断ポンチ39が固定されている。クリンパ36は端子6の導体圧着片15に対する第一クリンパ37と被覆圧着片16に対する第二クリンパ38とで構成され、幅方向中央に各圧着片15,16をカール状に湾曲させる縦方向の溝(図示せず)を有している。
【0024】
端子16の電線圧着部14と切断部10の高さ方向の位置に応じて、切断ポンチ39の先端はクリンパ36の先端よりも高く位置し、クリンパ36の溝底(図示せず)の位置は、図9の如く切断ポンチ39の先端よりもやや高く位置している。図3で端子6の切断部10の下にポンチ受け44が位置し、電線圧着部14の下にアンビル41が位置している。アンビル41は電線圧着部14の底部側を支持する面を先端に有し、導体圧着片15に対する第一アンビル42と被覆圧着片16に対する第二アンビル43とで構成されている。クリンパ36、アンビル41、切断ポンチ39、ポンチ受け44は共に金属で形成されている。
【0025】
図4〜図5に示す如く、切断ポンチ39は横断面矩形(正方形)状の棒状に形成され、図5の如く先端部中央に、端子6(図3)の切断部10を係合させる端子係合溝49を有している。端子係合溝49は端子長手方向に延び、切断ポンチ39の前後面50,51(図4)を貫通している。端子係合溝49の幅は端子6の切断部10の幅よりも若干広く設定されている。端子係合溝49の前後端が端子切断用のエッジ(刃部)52となっている。
【0026】
端子係合溝49の両側に一対の矩形状の突部53が構成されている。突部53の前後面はテーパ状に傾斜し、このテーパガイド面54でポンチ受け44内にスムーズに挿入可能となっている。テーパガイド面54はエッジ52のやや下側まで延びている。切断ポンチ39の四隅には長手方向にテーパ面取55が施され、ポンチ受け44への挿入性が高められている。
【0027】
ポンチ受け44は先端部に矩形状のポンチ挿入溝56を有している。ポンチ挿入溝56は端子係合溝49とは直交する方向に延び、ポンチ受け44の左右の側面57を貫通している。ポンチ挿入溝56の最低深さは切断ポンチ39のエッジ52を中程まで十分に挿入可能な深さに設定されている。
【0028】
ポンチ挿入溝56の前後の内壁58の上端部には一対の矩形状の突部59が形成され、一対の突部59によってポンチ挿入溝56の上部開口60が狭められている。一対の突部59の間隙は切断ポンチ39の前後のエッジ52の間隔すなわち切断ポンチ39の前後幅よりも若干広く設定され、各突部59の上端の直角な角部が端子切断用のエッジ(刃部)61となっている。
【0029】
各突部59の先端面は切断ポンチ39の前後面に沿う平坦な垂直面59aとなっている。垂直面59aの長さは切断ポンチ39の先端から端子係合溝49の底面までの距離とほぼ等しい。各突部59の下側に幅広部62が構成され、幅広部62の幅は端子6の切断カスすなわち切断ポンチ39の前後幅よりも十分に長く設定されている。幅広部62は切断カス逃がし部として作用し、切断カスをポンチ挿入溝56の内壁面58に張り付けずにスムーズに落下させる。
【0030】
図5の如くポンチ挿入溝56の底面はポンチ受け44の一側面に向けテーパ状に傾斜している。この傾斜面63に沿って端子6の切断カスが外部に滑り落ち(排出)可能となっている。
【0031】
図3において、ポンチ受け44とアンビル41との間に支持45のガイド壁64が位置し、支持45はポンチ受け44に沿って高さ方向にスライド自在となっている。図3のバッテリ接続プレート1の仮セット状態から支持45をバッテリ接続プレート1と一体に昇降シリンダ等の昇降手段(図示せず)で下降させ、図6の如く端子6の切断部10をポンチ受け44の上端に接して位置させ、電線圧着部14をアンビル41の上面に載置させる。次いで電線65を電線圧着部14にセットする。電線65はバッテリ接続プレート1の後部側の電線挿通用のスリット29,30に保持され、その状態で電線65の端末の導体部が電線圧着部14内にセットされる。導体部の先端はプレート本体2の枠状部20に突き当たって位置決めされる。
【0032】
図7の如く、端子6の中間連結部18の凹部66がポンチ受け44の上端部(凸部)に隙間なく係合する。凹部66は立上げ部8と前側接続部9と後側接続部11と切断部10と立下げ部12とで構成されている。立上げ部8がポンチ受け44の後端面68に接し、各接続部9,11がポンチ受け44の上端面に沿い、切断部10がポンチ挿入溝56の上部開口60で両突部59の間に架け渡され、立下げ部12がポンチ受け44の前端面67に接して位置する。
【0033】
端子6の凹部66がポンチ受け44の上端部に係合することで、端子6が長手方向に位置決めされて且つ安定に保持される。端子6の幅方向の位置決めは、図6でバッテリ接続プレート1を固定した支持台45がポンチ受け44に対して位置決めされることで行われる。各端子6の凹部66はプレート本体1の枠状部20,23(図1)内に位置している。
【0034】
図8の如く、アプリケータ33のラム35を下降させることで、クリンパ36と切断ポンチ39が一体に下降し、図9の如く、クリンパ36とアンビル41の間で端子6の電線圧着部14が加締められて、電線圧着部14に電線65が圧着接続されると共に、切断ポンチ39で端子6の切断部10が切断される。第一クリンパ37で導体圧着片15が圧着され、第二クリンパ38で被覆圧着片16が圧着される。
【0035】
端子6の切断に際しては、切断部10が切断ポンチ39の端子係合溝49内に導入されて正確に位置決めされると共に、前後のエッジ52とポンチ受け44の上端のエッジ61との間で剪断され、端子係合溝49が完全にポンチ挿入溝56の幅広部62内に進入した時点で、切断カス10′が傾斜面63に沿って外部に排出される。切断ポンチ39の先端に張り付いた切断カス10′は、切断ポンチ39の上昇時にポンチ受け44の突部59の下端に当たって落下する。これにより、切断カス10′の収拾が確実に行われる。排出用の傾斜面63は図示しない切断カス収容箱に続いている。
【0036】
電線65の圧着及び端子6の切断後にラム35(図8)が上昇し、図6の上死点に復帰する。ラム35の昇降は前記駆動手段(図示せず)で行われる。図10〜図11の如く、端子6の切断部10(図7)は前後の幅広の接続部9,11の付根から完全に切断される。全ての端子6に電線65を圧着し、且つ端子6を切断した後に、前後の接続部9,11の間にヒューズ(図示せず)が接続される。
【0037】
各端子6の圧着及び切断は一つのラム35(図6)に対して支持台45(図6)をバッテリ接続プレート1と一体に横方向にスライドさせることで効率的に行われる。
【0038】
図12は上記バッテリ接続プレート1の端子加工装置71すなわち端子圧着兼切断用の装置の詳細構造を示すものである。
【0039】
アプリケータ33のラム35はトグルリンク72で昇降される。トグルリンク72はフレーム34内の図示しないモータで駆動される。フレーム34の基台70上に水平方向のレール73が配置され、レール73にスライダ74が係合し、スライダ74に支持45が固定されている。支持45の上側ホルダ45aにバッテリ接続プレート1が固定されている。バッテリ接続プレート1は上側ホルダ45aの水平方向のシリンダ75で押し付け固定されている。上側ホルダ45aは左右一対の垂直方向のシリンダ76で昇降可能である。
【0040】
バッテリ接続プレート1の端子6(図6)がクリンパ36とアンビル41の間に位置している。ラム35の昇降で一つの端子6の圧着と切断とを行った後、レール73に沿って端子6の一ピッチ分の距離だけ支持45を移動させ、隣接の端子6の圧着と切断を行う。これにより、複数の端子6の圧着と切断とが効率良く行われる。支持45は例えば図示しないボールねじ軸とサーボモータといった駆動手段でレール73に沿って移動する。あるいは作業者が手動で支持45をレール73に沿ってスライド移動させることも可能である。
【0041】
図3と図6におけるバッテリ接続プレート1の昇降動作は図12の垂直方向のシリンダ76で行われる。一つの端子6の圧着と切断を行った後、バッテリ接続プレート1を図3の状態に上昇させ、レール73(図12)に沿ってバッテリ接続プレート1を端子一ピッチ分の距離だけ水平移動させた後、図6の状態に下降させて隣接の端子6の圧着と切断を行う。全ての端子6を加工し終えたら、シリンダ75(図12)によるロックを解除し、バッテリ接続プレート1を支持45から取り外す。
【0042】
【発明の効果】
以上の如く、請求項1,記載の発明によれば、ラムの一回の下降動作で、端子の電線圧着部に電線を圧着接続させると同時に、端子の中間連結部を切断することができるから、中間連結部の切断作業を含めて端子の加工作業が効率化される。また、従来の手作業に較べて、切断ポンチによって中間連結部の切断が正確に行われ、ヒューズの接続性が向上する。
【0043】
また、一つの端子の圧着と切断を行った後、支持を移動させて次の端子をラムの下に位置させて端子の圧着と切断を行うことができるから、複数の端子を有するバッテリ接続プレートの端子加工を効率良く行うことができる。
【0044】
また、請求項2,8記載の発明によれば、ポンチ受けが端子の凹部に係合することで、中間連結部の長手方向の位置出しが行われると共に、中間連結部がポンチ受けでガタ付きなく確実に支持されて、中間連結部が位置ずれなく正確に切断される。これにより切断精度が向上する。
【0045】
また、請求項記載の発明によれば、切断ポンチの端子係合溝で端子の中間連結部が幅方向に正確に位置決めされつつ、端子係合溝の前後端のエッジで確実に切断される。これにより端子の切断精度が向上する。
【0046】
また、請求項記載の発明によれば、切断ポンチがテーパガイド面でポンチ受け内にスムーズに挿入される。これにより、切断ポンチやポンチ受けのかじりによる磨耗や破損等が防止され、寿命が向上する。
【0047】
また、請求項記載の発明によれば、中間連結部の切断カスが幅広の切断カス逃がし部によってポンチ挿入溝の内壁に張り付かずに自重で落下するから、切断カスの収拾が容易化する。切断カスが切断ポンチに張り付いた場合は、切断ポンチの上昇時に切断カスがポンチ挿入溝の入口部に当たってポンチ挿入溝内に落ちるから、同様に切断カスの収拾が容易化する。
【0048】
また、請求項6,9記載の発明によれば、切断カスが傾斜面に沿って自動的に外部に排出されるから、切断カスの収拾が容易化する。
