Abstract
Description
よって、インバータの前面に絶縁部材が配置されているにも拘らず、インバータから発熱した熱を効果的に放熱させることができ、磁気シールド及絶縁性を確保しつつ冷却効果をも促進することが可能となる。
樹脂製にすることで、軽量で成形が容易な絶縁部材を得ることが可能となる。
このような構成においては、絶縁部材が配置される空間が狭い場合でも、絶縁部材とインバータとの間、及び、絶縁部材とカバーとの間の通路面積を確保することが可能となり、通路が狭められて対流効果が低減する不都合がなくなる。
このような構成とすることで、カバーの強度を確保すると共に振動を抑えることが可能となり、また、カバーと外気あるいは内気が接触する面積を増やすことでインバータ収容空間の冷却効果を高めることが可能となる。
一般的に、ハウジングとカバーとの間は、気密性が要請されるが、絶縁部材は、インバータ収容空間内に固定すればいいので、気密性を必要としない。しかし、同じ固定具でカバーと絶縁部材とを固定する場合には、気密性を確保するための寸法精度や表面精度を絶縁部材に対しても要請しなければならなくなる。そこで、絶縁部材の組み付けとカバーの組み付けとを行う固定具を異なるものとすることで、絶縁部材において、気密性を確保するための寸法精度や表面精度が不要となる。
尚、図1において、図中右側を圧縮機の前方、図中左側を圧縮機の後方としている。
この例では、インバータ収容空間12は、インバータ収容ハウジング部材2cにカバー16をネジ17によって固定することで画成されている。
したがって、電動型圧縮機1は、前記圧縮機構3、前記電動機4、およびインバータ5(インバータ収容空間12)がこの順で水平方向に配置されている。
この例において、ターミナル(気密端子)13は、硬質部材で形成された本体部13aと、この本体部13aに貫通固定された複数(3本)の端子ピン13bとを有して構成されているもので、端子ピン13bが気密に貫通する本体部13aには、貫通孔7bの周縁に係止可能なフランジ部13cを有している。このようなターミナル13は、貫通孔7bに対して電動機収容空間11から挿入され、本体部13aの一部をインバータ収容空間12に突出させることで仕切壁7に固定し、貫通孔7bを気密に封止している。
そして、ターミナル13には、図示しないケーブルを介してインバータ回路に接続されたインバータ側コネクタ14が、インバータ回路基板51の仕切壁7と対峙する側とは反対側から端子ピン13bのインバータ回路基板51の通孔51bから突出した部分に装着され、また、図示しないケーブルを介して電動機4のステータ41に接続された電動機側コネクタ15が、ターミナル13の後方側から端子ピン13bの電動機収容空間11に突出している部分に装着されている。したがって、インバータ回路とステータ41とはターミナル13を介して電気的に接続され、電動機4に対してインバータ5から給電するようになっている。
この絶縁部材21は、インバータ回路基板51のほぼ全体を覆う大きさに形成されている。この例において、絶縁部材21は、略矩形状に形成され、四隅部分をインバータ収容ハウジング部材2cの凹部12aの周縁に形成されたネジ受けボス部22にネジ23によって止めすることでインバータ回路基板51に対して離して固定されている。
しかも、上述の構成においては、カバー16の表面にリブ27が形成されているので、外気あるいは内気と接触するカバー16の表面積を増やすことができ、カバー16の内側での冷却機能を高めることが可能となる。
カバー16と絶縁部材21とを同じ固定具で固定する場合には、気密性を確保するための寸法精度や表面精度を絶縁部材に対しても要請しなければならなくなり、コストが上昇することになる。しかしながら、絶縁部材21の固定具(ネジ23)をカバー16の固定具(ネジ17)とは異なるものとすることで、絶縁部材21において、気密性を確保するための寸法精度や表面精度が不要となる。
