Description

【０００１】
【発明の属する技術分野】
本発明は、車両のバッテリが上がった場合に、バッテリに直接ではなく、給電端子にブースタケーブルを接続するように構成した給電用導電部材とそれを備えた給電ブロックに関するものである。
【０００２】
【従来の技術】
例えばエンジンとモータを混載したハイブリッド車等においては、車両後部にバッテリを搭載し、車両前側のエンジンルームに、バッテリ上がり時の電源供給を可能とする電源供給部を搭載している（例えば特許文献１参照）。
【０００３】
図３に示す如く電源供給部４１はジャンプスタート端子ボックス４２を備え、ボックス４２の各端子４３，４４に、バッテリに続くハーネス４５と、スタータモータとオルタネータに続く各ハーネス４６とが接続されている。
【０００４】
バッテリ上がり時に、バッテリに続く端子４３の短円柱状の接続部４３ａに図４のブースタケーブル４７の先端の導電クランプ４８を内側のばね部材のばね力で把持させて接続し、他車のバッテリ等から本車のバッテリに電源を給電しつつスタータモータを回してエンジンを始動する。このように、一々車両後部のバッテリ室を開けずに、車両前部のボンネットのみを開けることで、バッテリ上がりに容易に対応することができる。
【０００５】
バッテリからの電源ケーブルを接続する電気接続ブロックとしては、例えば図５に示すようなものが開示されている（特許文献２参照）。
【０００６】
この電気接続ブロック５１は、合成樹脂製のケース５２と、ケース５２を覆う合成樹脂製の防水用のメインカバー５３とサブカバー５４とを備え、サブカバー５４はメインカバー５３の切欠凹部５５内に嵌め込まれ、ケース５２側の電源接続端子（スタッドボルト）５６を覆う。カバー５３はケース５２に係止手段５７，５８で固定される。
【０００７】
電源接続端子５６はケース５２の凹部５９内に立設され、電源接続端子５６の両側にヒューズ装着部６０，６１が配設されている。サブカバー５４には電源ケーブル６２が固定され、電源ケーブル６２の先端には、電源接続端子５６に対する挿通孔を有する板端子６３が接続されている。ヒューズ装着部６０，６１内の端子はバスバー（図示せず）に一体に形成され、バスバーと電源接続端子５６とはナット締めで接続される。

【発明が解決しようとする課題】
しかしながら、上記従来の端子ボックス４２の給電端子４３（図３）や電気接続ブロック５１の接続端子５６（図５）は細い円柱状であるために、図４のブースタケーブル４７の導電クランプ４８で把持しにくく、導電クランプ４８がぐらついて安定しにくく、接続作業性が悪いと共に、導電クランプ４８との接触面積が小さく、電気的接触性が悪く、これらにより給電の信頼性に欠けるという問題があった。
【００１０】
本発明は、上記した点に鑑み、車両のバッテリ上がり時に給電端子をブースタケーブルの導電クランプで容易に且つしっかりと且つ大きな接触面積で把持でき、接続（給電）作業性と電気的接続の信頼性を高めることのできる給電用導電部材とそれを備えた給電ブロックを提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１に係る給電用導電部材は、バッテリに電気的に導通される導通部分と、該導通部分に続き、ブースタケーブルを接続可能な給電端子とを備える給電用導電部材において、前記給電端子が横断面略角型状に形成され、前記導通部分から交差方向に長く突出されたことを特徴とする。
上記構成により、車両のバッテリ上がり時に、外部に長く突出した給電端子にブースタケーブルの導電クランプを容易に且つ確実に把持させることができる。また、給電端子が横断面略角型状であるから、ブースタケーブルの導電クランプを把持した際に導電クランプがぐらつかず安定性が良く、導電クランプとの接触面積も断面円形の給電端子の場合に較べて大きく、通電抵抗が小さく、電気的接触性が良好である。
【００１２】
請求項２に係る給電用導電部材は、請求項１記載の給電用導電部材において、前記給電端子が雄タブ状に形成されたことを特徴とする。
上記構成により、ブースタケーブルの導電クランプで雄タブ状の給電端子を板厚方向に把持することで、導電クランプが給電端子の平坦な表裏面に大きな面積で接触する。また、導電クランプで雄タブ状の給電端子を板幅方向に把持することで、導電クランプが大きく開いて維持され、大きなばね力で給電端子を強く把持する。
【００１３】
請求項３に係る給電用導電部材は、請求項２記載の給電用導電部材において、前記給電端子の板厚が前記導通部分の板厚よりも厚く形成されたことを特徴とする。
上記構成により、ブースタケーブルの導電クランプで雄タブ状の給電端子を板厚方向に把持した際に、導電クランプが大きく開いて維持され、大きなばね力で給電端子を強く把持する。
【００１４】
請求項４に係る給電用導電部材は、請求項１記載の給電用導電部材において、前記給電端子が、基板部と、該基板部の両側で該基板部と交差する方向に突出した一対の突板部とで横断面略コの字状に形成されたことを特徴とする。
上記構成により、給電端子の厚さ方向の寸法が基板部の板厚と突板部の長さとの総和で大きくなり、ブースタケーブルの導電クランプで給電端子を厚さ方向に把持しやすくなると共に、導電クランプのばね部材による把持力が大きくなって、電気的接触性が高まる。給電端子の幅方向についても、ブースタケーブルの導電クランプが両突板部の表面を把持するように掴むから、導電クランプと給電端子との接触面積が増して、電気的接触性が高まる。
【００１５】
請求項５に係る給電用導電部材は、請求項１〜４の何れか１項に記載の給電用導電部材において、前記導通部分がバスバーであり、前記給電端子が該バスバーに一体に形成されたことを特徴とする。
上記構成により、給電端子とバスバーとで成る給電用導電部材を導電金属板から打ち抜き及び折り曲げ成型により、容易に且つ生産性良く低コストで形成することができる。例えば、断面略コの字状の給電端子については、平板状のバスバーの長手方向の延長部分に基板部を形成し、基板部を基端から折り曲げると共に、基板部の両側の延長部分を折り曲げて一対の突板部とすることで、給電端子を含む給電用導電部材を容易に効率良く低コストで形成することができる。
【００１６】
請求項６に係る給電用導電部材を備えた給電ブロックは、請求項１〜５の何れか１項に記載の給電用導電部材が絶縁性のベースに装着され、前記給電端子が該ベースから外部に長く突出したことを特徴とする。
上記構成により、車両のバッテリ上がり時に、外部に長く突出した給電端子にブースタケーブルの導電クランプを容易に且つ確実に把持させることができる。
【００１７】
請求項７に係る給電用導電部材を備えた給電ブロックは、請求項６記載の給電用導電部材を備えた給電ブロックにおいて、前記バッテリからの回路を接続するボルトが前記ベースに突設され、該ボルトに前記導通部分が挿通接続され、前記給電端子が該ボルトよりも長く突出されたことを特徴とする。
上記構成により、ブースタケーブルの導電クランプをボルトに把持させる場合に較べて、長く突出した給電端子に導電クランプを容易に且つボルトに邪魔されることなく確実に把持させることができる。
【００１８】
【発明の実施の形態】
以下に本発明の実施の形態を図面に基づいて詳細に説明する。
図１は、本発明に係る給電用導電部材の一実施形態とそれを備えた給電ブロックを示すものである。
【００１９】
給電ブロック４０は、合成樹脂製（絶縁性）のベース２と、ベース上に装着される給電用導電部材３０とを備えている。ベース２は水平な基台部２１と、基台部２１の周囲（半周以上）に立設された側壁１９と、側壁１９から基台部２１と平行に突出されたブラケット２２とを備えている。
基台部２１に導電金属製の二本のボルト２３が垂直に植設され、ボルト２３の頭部（図示せず）は基台部２１内に埋入固定されている。二本のボルト２３を貫通して基台部２１上に金属製の給電用導電部材３０のバスバー（導通部分）２４が水平に配置されている。
【００２０】
バスバー２４には二本のボルト２３を挿通する円形の孔部２５が並列に設けられ、バスバー２４の一端に長い雄タブ状の給電端子６が一体に上向き（垂直）に突出形成されている。バスバー２４と給電端子６とで給電用導電部材３０が構成されている。孔部２５の周縁がバッテリからの回路（電源ケーブル）に電気的に導通される導通部３５として作用する。各ボルト２３はベース２の側壁１９よりも高く突出され、給電端子６はボルト２３よりも二倍ないしそれ以上の高さで突出されている。
【００２１】
給電端子６はバスバー２４よりも厚肉に形成され、板厚方向に表裏の平坦面６ｂを有し、板幅方向の両端と上端とに略円弧状の湾曲面６ｃを有している。給電端子６が厚肉であるから、ブースタケーブルの導電クランプ（図４参照）で強く給電端子６を把持することができ、しかも表裏の平坦面６ｂで導電クランプを従来の円柱状の給電端子に較べて大きな接触面積で安定して接触させることができる。また、給電端子６の横幅が広いから、同様に導電クランプを強く把持させることができる。その際、両側の湾曲面６ｃに導電クランプを安定に保持させることができる。
【００２２】
バスバー２４はベース２の側壁１９の上端１９ａよりも下方に位置している。バスバー２４の両側には下向きの位置決め突部（図示せず）が設けられ、基台部２１の上面（バスバー２４を載置する面）に、位置決め突部を進入係合させる穴部（図示せず）が設けられている。
【００２３】
バスバー２４を基台部２１上にセットし、貫通した一方のボルト２３にバッテリからの電線のプラス電極の端子（図示しない電線に接続された端子）をナット（図示せず）で締め付け接続し、他方のボルト２３に例えばオルタネータからの電線の端子を同様にナットで締め付け接続する。バスバー２４はベース２の基台部２１上にそれらのナットで締付固定される。バスバー２４の一側端には各電線の板状の端子（図示せず）を位置決めする三本の突出部２６が上向きに設けられている。
【００２４】
給電端子６の基端部６ａはベース２の側壁１９の略コの字状の部分１９ｂで囲まれて位置する。ベース２はブラケット２２の孔部２７で車両ボディやパネル等にネジ締め固定される。給電端子６はベース２の側壁１９の上端１９ａよりも遙かに高く上向きに突出して位置する。
【００２５】
なお、上端及び両端の湾曲面６ｃがない雄タブ状の給電端子も有効である。また、図１の給電端子以外で、横断面四角形状（正方形や長方形）等の横断面矩形状の給電端子も使用可能である。
【００２６】
図２は、給電端子の他の実施形態とそれを用いた給電ブロックを示すものである。図１の実施形態と同様の構成部分には同一の符号を用いて詳細な説明を省略する。
【００２７】
この給電端子６’は横断面略コの字状に形成されている。すなわち、バスバー２４に続いて垂直に延びる基板部３１と、基板部３１の両側で内向きに直角に折り曲げられて続く左右一対の平行な突板部３２とで給電端子６’が構成されている。突板部３２と基板部３１とのなす角度は９０度よりも若干大きくても構わない。
【００２８】
突板部３２の突出長さＬ１は基板部３１の横幅寸法Ｌ２の半分程度ないしそれ以上に設定される。各突板部３２の突出長さＬ１は同じである。突板部３２はブースタケーブルの導電クランプで掴む部位すなわち上半部だけ大きく突出していればよく、下半部は切欠（３３）されて小さな突出量で形成されている。基板部３１と突板部３２の板厚は同じであり、これらはバスバー２４の板厚と同じである。基板部３１の下端側からバスバー２４にかけて補強用のリブ３４が内向きに膨出形成されている。
【００２９】
給電端子６’とバスバー２４とで給電用導電部材３０’が構成され、給電用導電部材３０’と合成樹脂製のベース２とで導電金属製のボルト２３とで給電ブロック４０’が構成されている。給電端子６’の基部６ａ’はベース２の側壁１９ｂで囲まれている。
【００３０】
給電用導電部材３０’の製造に際しては、導電金属板（図示せず）からバスバー２４と給電端子６’とを一体に打ち抜き、バスバー２４と給電端子６’の基板部３１とを平面的に連続させ、基板部３１の両側で突板部３２を内向きに直角ないしほぼ直角に折り曲げると共に、バスバー２４と基板部３１との境部から基板部３１をバスバー２４に対して直角に折り曲げて立ち上げる。これにより、容易に且つ生産性良く給電用導電部材３０’を形成することができる。
【００３１】
ブースタケーブルの導電クランプで給電端子６’を板厚方向に把持する場合には、両側の突板部３２が突出しているから、導電クランプが大きく開かれ、強いばね力で給電端子６’が把持されると共に、基板部３１の外側面が平坦面であるから、導電クランプに大きな面積で接触する。また、導電クランプで給電端子６’を板幅方向に把持する場合には、板幅Ｌ２が大きいから、上記以上に大きな力で導電クランプが給電端子６’を把持し、しかも両側の突板部３２の外側の平坦面が大きな面積で導電クランプに面接触する。
【００３２】
なお、突板部３２の突出長さＬ１と基板部３１の幅Ｌ２とを同程度に形成することも可能である。また、両側の突板部３２を少し外向きに開いて、導電クランプの開閉形態に対応して突板部３２の外面を正確に面接触させることも可能である。
【００３３】
上記各実施形態においては、給電ブロック４０をバッテリと共にエンジンルーム内に置くことも可能であり、エンジンルーム以外でも適宜箇所に設置可することができる。また、車両ボディやパネルへ等のベース２の固定手段はブラケット２２に限らず、種々の形態を適宜設定可能である。また、給電端子６，６’の向きは上向きに限らず、横向きや斜め方向等適宜設定可能である。例えばバスバー２４に対して直角ではなく傾斜方向に給電端子６，６’を突出させることも可能である。
【００３４】
また、給電ブロック４０，４０’は合成樹脂製のカバーで覆われてもよく、あるいはリレーやヒューズ等を有する大きな電気接続箱（図示せず）の一部分を構成するものであってもよい。給電端子６，６’のみをカバーから外部に長く突出させてもよい。また、バッテリやオルタネータ等からの電線（回路）の端子（図示せず）をバスバー２４に接続する手段はボルト２３とナットに限らず、端子同士の接続等、種々の形態を適宜設定可能である。
【００３５】
【発明の効果】
以上の如く、請求項１記載の発明によれば、車両のバッテリ上がり時に、給電端子にブースタケーブルの導電クランプを容易に且つ確実に把持させることができるから、給電作業性が向上する。また、ブースタケーブルの導電クランプで給電端子をぐらつきなく安定に把持でき、しかも断面円形の給電端子に較べて把持時の接触面積が増大するから、電気的接続（給電）の信頼性が向上する。

The present invention relates to a power supply conductive member configured to connect a booster cable to a power supply terminal instead of directly to a battery when a battery of a vehicle goes up, and a power supply block including the same.
[0002]
[Prior art]
For example, in a hybrid vehicle or the like in which an engine and a motor are mixedly mounted, a battery is mounted on a rear portion of the vehicle, and a power supply unit for supplying power when the battery is dead is mounted in an engine room on the front side of the vehicle (for example, see Patent Document 1).
[0003]
As shown in FIG. 3, the power supply unit 41 includes a jump start terminal box 42, and a harness 45 connected to the battery and a harness 46 connected to the starter motor and the alternator are connected to the terminals 43 and 44 of the box 42. .
[0004]
When the battery goes up, the conductive clamp 48 at the end of the booster cable 47 shown in FIG. 4 is connected to the short cylindrical connecting portion 43a of the terminal 43 following the battery by being gripped by the spring force of the inner spring member, and is connected to a battery of another vehicle. The engine is started by turning the starter motor while supplying power to the battery of the vehicle. In this way, by opening only the hood at the front of the vehicle without opening the battery compartment at the rear of the vehicle one by one, it is possible to easily cope with a dead battery.
[0005]
As an electric connection block for connecting a power cable from a battery, for example, one shown in FIG. 5 is disclosed (see Patent Document 2).

It is fitted and covers the power supply connection terminal (stud bolt) 56 on the case 52 side. The cover 53 is fixed to the case 52 by locking means 57 and 58.
[0007]
The power supply connection terminal 56 is provided upright in the concave portion 59 of the case 52, and fuse mounting portions 60 and 61 are provided on both sides of the power supply connection terminal 56. A power cable 62 is fixed to the sub cover 54, and a plate terminal 63 having an insertion hole for the power connection terminal 56 is connected to a tip of the power cable 62.

[0009]
[Problems to be solved by the invention]
However, since the power supply terminal 43 (FIG. 3) of the conventional terminal box 42 and the connection terminal 56 (FIG. 5) of the electric connection block 51 are thin columns, they are gripped by the conductive clamp 48 of the booster cable 47 shown in FIG. In addition, the conductive clamp 48 is difficult to stabilize due to wobbling, the connection workability is poor, the contact area with the conductive clamp 48 is small, the electrical contact is poor, and there is a problem that the reliability of power supply is lacking. .
[0010]
In view of the above, the present invention can easily and firmly hold the power supply terminal with the conductive clamp of the booster cable with a large contact area when the battery of the vehicle is dead, and thus, the connection (power supply) workability and the reliability of the electrical connection. It is an object of the present invention to provide a power-supplying conductive member that can increase the power consumption and a power supply block including the same.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a power supply conductive member according to claim 1 of the present invention includes a conductive portion electrically connected to a battery, and a power supply terminal to which a booster cable can be connected following the conductive portion. In the power supply conductive member provided, the power supply terminal is formed in a substantially rectangular shape in cross section, and is protruded from the conductive portion in a cross direction to be long.
According to the above configuration, when the battery of the vehicle is dead, the conductive clamp of the booster cable can be easily and reliably gripped by the power supply terminal that protrudes long outside. In addition, since the power supply terminal has a substantially square cross section, the conductive clamp of the booster cable does not move when gripping the conductive clamp, and has good stability. As compared with the above, the current-carrying resistance is small, and the electrical contact property is good.
[0012]
A power supply conductive member according to a second aspect is the power supply conductive member according to the first aspect, wherein the power supply terminal is formed in a male tab shape.
According to the above configuration, by gripping the male tab-shaped power supply terminal in the plate thickness direction with the conductive clamp of the booster cable, the conductive clamp contacts the flat front and back surfaces of the power supply terminal with a large area. Further, by gripping the male tab-shaped power supply terminal in the plate width direction with the conductive clamp, the conductive clamp is widely opened and maintained, and the power supply terminal is strongly gripped by a large spring force.
[0013]
According to a third aspect of the present invention, in the power supply conductive member according to the second aspect, a plate thickness of the power supply terminal is formed larger than a plate thickness of the conductive portion.
With the above configuration, when the male tab-shaped power supply terminal is gripped by the conductive clamp of the booster cable in the plate thickness direction, the conductive clamp is widely opened and maintained, and the power supply terminal is strongly gripped by a large spring force.
[0014]
The power supply conductive member according to claim 4 is the power supply conductive member according to claim 1, wherein the power supply terminal is a pair of projecting plates protruding in a direction intersecting the substrate portion on both sides of the substrate portion. And a cross section formed substantially in a U-shape.
With the above configuration, the dimension of the power supply terminal in the thickness direction is increased by the sum of the board thickness of the board portion and the length of the protruding plate portion. The gripping force of the spring member of the clamp is increased, and the electrical contact is enhanced. Also in the width direction of the power supply terminal, the conductive clamp of the booster cable grips so as to grip the surfaces of the both protruding plate portions, so that the contact area between the conductive clamp and the power supply terminal increases, and the electrical contact property increases.
[0015]

The power supply terminal 6 is formed thicker than the bus bar 24, has flat front and back surfaces 6b in the plate thickness direction, and has a substantially arc-shaped curved surface 6c at both ends and the upper end in the plate width direction. Since the power supply terminal 6 is thick, the power supply terminal 6 can be strongly gripped by the conductive clamp (see FIG. 4) of the booster cable, and the conductive clamp is connected to the conventional cylindrical power supply terminal by the front and back flat surfaces 6b. A stable contact can be achieved with a relatively large contact area. In addition, since the width of the power supply terminal 6 is wide, the conductive clamp can be similarly strongly gripped. At this time, the conductive clamps can be stably held on the curved surfaces 6c on both sides.
