Description
本実施の形態では、コネクタ40をポンプベース15の底面151に直接固定せず、図2に示すようにコネクタスペーサ41を介してコネクタ40を固定するようにした。それにより、コネクタ40の位置をポンプベース15の底面151から突出させることができ、電源部20とポンプベース15との間に電源側配線61を挟み込んでしまうという電源固定時における不具合の発生を防止することができる。
上述した実施の形態では、コネクタ40は、図2に示すようにコネクタピン403の真空側にポンプ側配線60が接続されると共に大気圧側に電源側配線61が接続される、フィードスルー方式のコネクタであった。しかし、コネクタ40の構成はこのような構成に限定されず、図8に示すような着脱可能なレセプタクル421とプラグ422とで構成されるコネクタ42であっても良い。その場合、レセプタクル421がコネクタスペーサ41に固定される。
