Description
本開示の目的は、電装品の小型化に貢献することができる端子台を提供することにある。
最初に本開示の実施形態を列記して説明する。
本開示の端子台は、
[1]電装品に電気的に接続される第1端子と、前記第1端子に電気的に接続される第2端子と、を備える端子台であって、前記第1端子又は前記第2端子には、前記第1端子又は前記第2端子を流れる電流を検出する電流センサが一体化されている。
この構成によれば、クリップ部によってバスバーを挟持するだけで、第1端子と第2端子とを接続することができるため、例えば、第1端子と第2端子とを接続するための部品を別途用意する必要が無く、端子台自体を小型化することができる。さらには、第1端子及び第2端子それぞれの寸法公差を吸収しつつも、第1端子と第2端子とを容易に電気的に接続することができる。
この構成によれば、第1端子の構成を簡素な構成にすることができるため、例えば、第1端子の構成が複雑化することによって、第1端子の周囲に存在する部品の設計を変更しなければならなくなってしまうといった問題を回避することができる。
この構成によれば、バスバーが、電流センサに取り囲まれる平板部を有しているため、第1端子に電流センサを容易に一体化することができる。
この構成によれば、第2端子の構成を簡素な構成にすることができるため、例えば、第2端子の構成が複雑化することによって、第2端子の周囲に存在する部品の設計を変更しなければならなくなってしまうといった問題を回避することができる。
この構成によれば、第1端子が、クリップ部から延びるとともに電流センサに取り囲まれる平板部を有しているため、第1端子に電流センサを容易に一体化することができる。
この構成によれば、付勢部材が一対の挟持部を互いに接近する方向へ付勢することにより、一対の挟持部によってバスバーを安定的に挟持することができる。したがって、第1端子と第2端子との電気的接続状態を安定的なものとすることができるため、信頼性を向上させることができる。
[9]電装品に電気的に接続される第1端子と、前記第1端子に電気的に接続される第2端子と、前記第2端子を保持する樹脂製のハウジングと、を備える端子台であって、前記ハウジングには、前記第2端子を流れる電流を検出する電流センサが一体化されている。
本開示の端子台の具体例を、以下に図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されるものではなく、特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。また、図面では、説明の便宜上、構成の一部を誇張又は簡略化して示す場合があり、各部分の寸法比率についても、実際と異なる場合がある。さらには、各部分の寸法比率については各図面で異なる場合がある。
以下、端子台の第1実施形態について説明する。
(全体構成)
図1に示す端子台10は、車両Vに搭載されている。車両Vは、モータ11と、インバータ12と、を備えている。モータ11及びインバータ12は、車両Vに搭載される電装品である。モータ11は、モータハウジング13内に収容されている。インバータ12は、回路基板12aを有している。端子台10は、モータハウジング13に取り付けられている。具体的には、端子台10は、例えば、ボルト14によってモータハウジング13に固定されている。そして、端子台10は、モータ11とインバータ12の回路基板12aとを電気的に接続している。
図1及び図2に示すように、端子台10は、ハウジング20と、インバータ端子30と、中継端子40と、モータ端子50と、電流センサ60と、を備えている。端子台10は、モータ11のU相、V相、及びW相に対応して、インバータ端子30、中継端子40、及びモータ端子50をそれぞれ3つずつ備えている。したがって、端子台10は、インバータ端子30、中継端子40、及びモータ端子50をそれぞれ複数組備えている。
各インバータ端子30は、細長薄板平板状のバスバーである。各インバータ端子30の厚みはそれぞれ同じである。各インバータ端子30の長辺が延びる方向である長辺方向の長さはそれぞれ同じである。各インバータ端子30の短辺が延びる方向を幅方向とすると、各インバータ端子30の幅はそれぞれ同じである。各インバータ端子30は、それぞれの厚み方向が一致し、且つそれぞれの幅方向が一致した状態で互いに配置されている。各インバータ端子30の長辺方向の一方に位置する第1端部は、インバータ12の回路基板12aに電気的に接続されている。したがって、各インバータ端子30は、電装品であるインバータ12に電気的に接続される第1端子である。各インバータ端子30の長辺方向の他方に位置する第2端部は、中継端子40に電気的に接続されている。
各モータ端子50は、細長薄板平板状のバスバーである。各モータ端子50の厚みはそれぞれ同じである。各モータ端子50の長辺が延びる方向である長辺方向の長さはそれぞれ同じである。各モータ端子50の短辺が延びる方向を幅方向とすると、各モータ端子50の幅はそれぞれ同じである。各モータ端子50は、それぞれの厚み方向が一致し、且つそれぞれの幅方向が一致した状態で互いに配置されている。各モータ端子50の長辺方向の一方に位置する第1端部は、モータ11のU相コイル、V相コイル、及びW相コイルそれぞれから引き出される各モータ配線11aにそれぞれ電気的に接続されている。なお、各モータ端子50の第1端部と各モータ配線11aとは、図示しない接続端子を介してそれぞれ接続されている。そして、各モータ端子50は、各モータ配線11aを介してモータ11に電気的に接続されている。したがって、各モータ端子50は、電装品であるモータ11に電気的に接続される第1端子である。なお、図1では、各モータ配線11aを模式的に図示している。各モータ端子50の長辺方向の他方に位置する第2端部は、中継端子40に電気的に接続されている。
図3に示すように、各中継端子40は、クリップ部である第1クリップ部41及び第2クリップ部42と、接続部43と、をそれぞれ有している。第1クリップ部41は、インバータ端子30の第2端部を挟持する。そして、中継端子40は、第1クリップ部41がインバータ端子30を挟持することにより、インバータ端子30に電気的に接続されている。第2クリップ部42は、モータ端子50の第2端部を挟持する。そして、中継端子40は、第2クリップ部42がモータ端子50を挟持することにより、モータ端子50に電気的に接続されている。したがって、中継端子40は、第1端子であるインバータ端子30及びモータ端子50にそれぞれ電気的に接続される第2端子である。
第1クリップ部41及び第2クリップ部42の構成は同じであるため、以下の説明では、第1クリップ部41の構成の説明を詳細に説明し、第2クリップ部42の構成の説明は、同一符号を付すなどして簡略化する。
図2に示すように、ハウジング20は、樹脂製である。ハウジング20は、板状である。ハウジング20は、ボルト14が挿通可能なボルト挿通孔21を有している。ハウジング20は、各中継端子40を保持している。具体的には、ハウジング20は、各中継端子40の接続部43の一部分を保持している。各中継端子40とハウジング20とは、インサート成形により一体化されている。
図4及び図5に示すように、電流センサ60は、各インバータ端子30の平板部31に一体化されている。電流センサ60は、それぞれのインバータ端子30に対応して設けられたセンサ部品61と、複数のセンサ部品61を内蔵するベース部材62と、を有している。ベース部材62は、樹脂製である。ベース部材62は、長四角ブロック状である。ベース部材62の長辺が延びる方向は、各インバータ端子30の幅方向に一致している。ベース部材62は、各インバータ端子30の平板部31を取り囲んでいる。
次に、第1実施形態の作用について説明する。
インバータ12の回路基板12aから各インバータ端子30に流れた電流は、各中継端子40、各モータ端子50、及び各モータ配線11aを介してモータ11に供給される。インバータ12の回路基板12aから各インバータ端子30に電流が流れると、各コア部材63に磁束が発生し、各コア部材63で発生した磁束が各ホール素子64を通過する。これにより、各ホール素子64には、磁束に基づいたホール電圧が生じる。ホール電圧は、各インバータ端子30を流れる電流の値に比例している。したがって、電流センサ60は、各インバータ端子30を流れる電流を検出していると言える。
(1-1)インバータ端子30には、インバータ端子30を流れる電流を検出する電流センサ60が一体化されている。この構成によれば、インバータ12が電流センサ60を備えている必要が無いため、例えば、インバータ12が電流センサ60を備えている構成である場合のように、電流センサ60を備えている分だけ、インバータ12が大型化してしまうといったことが無くなる。したがって、インバータ12の小型化に貢献することができる。
次に、端子台の第2実施形態について説明する。なお、以下で説明する実施形態では、第1実施形態との相違点について主に説明し、第1実施形態と同様の構成には同じ符号を付して、説明の一部又は全部を割愛する場合がある。
図7に示すように、各中継端子70は、細長薄板平板状のバスバーである。各中継端子70の厚みはそれぞれ同じである。各中継端子70の長辺が延びる方向である長辺方向の長さはそれぞれ同じである。各中継端子70の短辺が延びる方向を幅方向とすると、各中継端子70の幅はそれぞれ同じである。各中継端子70は、それぞれの厚み方向が一致し、且つそれぞれの幅方向が一致した状態で互いに配置されている。各中継端子70の長辺方向の一方に位置する第1端部は、各インバータ端子80に電気的に接続されている。したがって、中継端子70は、第1端子であるインバータ端子80に電気的に接続される第2端子である。なお、各中継端子70の長辺方向の他方に位置する第2端部は、図示しない各モータ端子に電気的に接続されている。
各インバータ端子80は、電装品であるインバータ12に電気的に接続される第1端子である。各インバータ端子80は、クリップ部81と、クリップ部81から延びる平板部82と、をそれぞれ有している。なお、クリップ部81の構成は、第1実施形態で説明した第1クリップ部41及び第2クリップ部42の構成と同じであるため、同一符号を付すなどして、その詳細な説明を省略する。
第2実施形態では、第1実施形態の効果(1-1)、(1-5)、及び(1-6)と同様な効果に加えて、以下の効果を得ることができる。
次に、端子台の第3実施形態について説明する。
図8に示すように、電流センサ60は、各中継端子40の接続部43に一体化されている。各中継端子40の接続部43におけるハウジング20からの突出長さは、第1クリップ部41側の部分の突出長さと第2クリップ部42側の部分の突出長さとで異なっている。具体的には、接続部43における第1クリップ部41側の部分のハウジング20からの突出長さは、接続部43における第2クリップ部42側の部分のハウジング20からの突出長さよりも長くなっている。そして、電流センサ60は、各中継端子40の接続部43におけるハウジング20と第1クリップ部41との間に位置する部位に一体化されている。
第3実施形態では、第1実施形態の効果(1-1)、(1-2)、(1-3)、(1-5)、及び(1-6)と同様な効果に加えて、以下の効果を得ることができる。
