【発明の属する技術分野】
本発明は、固定子巻線の巻線端末線をピン端子にからげて電気的接続するとともに、これと口出し線とも電気的接続することのできるコンデンサ電動機の巻線端末処理用の端子台に関する。
【０００２】
【従来の技術】
従来、この種のコンデンサ電動機の巻線端末処理用の端子台においては、固定子鉄芯と固定子巻線の間に介在する前記絶縁体に設けたピン端子に固定子巻線の端末線をからげて半田付けなどにより電気的接続をした後、外部接続用の口出し線を有する端子台を前記固定子の巻線端末に装着し、この導電部と前記ピン端子をさらに半田付けなどにより電気的に接続する組立方法のものが知られている（例えば特許文献１参照）。
【０００３】
以下、そのコンデンサ電動機の巻線端末処理用の端子台について図６および図７を参照しながら説明する。
【０００４】
図８および図９に示すように、固定子鉄心１０１に絶縁体１０２を介して巻線１０３を巻装し、その巻線端末線１０４は前記絶縁体１０２に設けたピン端子１０５に絡げて電気的接続され、さらにこのピン端子１０５はコンデンサ１０７および温度フューズ１０８を配設した端子台１０９の導電部１１０の一部と電気的接続され、口出し線１１１とも接続される。それぞれを電気的に接続する。また、端子台１０９を反負荷側の巻線端末に装着した固定子１１２はハウジングＢ１１３の正規位置に圧入嵌合したのち回転子１１４を挿入しハウジングＡ１１５を組み合わせてコンデンサ電動機を完成する構成であった。

【０００６】
【発明が解決しようとする課題】
このような従来の構成では、電動機組立時に回転子１１４を挿入するために端子台１０９の中央部に挿通孔１１６を設ける必要があるため、コンデンサ１０７、温度フューズ１０８の設置スペースおよび導電部１１０の配置スペース等が制限され、したがって内蔵するコンデンサの容量も制限されるという課題があり、これらの制限を緩和、削除し、内蔵可能なコンデンサの容量範囲を拡大することが要求されている。
【０００７】
また、複数のピン端子１０５と端子台１０９の導電部１１０との電気的接続など端子台１０９装着時の組立作業に手間がかかるという課題があり、この組立作業の容易化が要求されている。
【０００８】
本発明は、このような従来の課題を解決するものであり、コンデンサをハウジングの内部に収納する電動機において、固定子に装着する端子台に設置する部品の設置スペースの確保と内蔵するコンデンサの容量範囲の拡大および巻線端末処理時の組立作業の容易化が可能なコンデンサ電動機の巻線端末処理用の端子台を提供することを目的としている。
【０００９】
【課題を解決するための手段】
本発明のコンデンサ電動機の巻線端末処理用の端子台は上記目的を達成するために、固定子鉄心に絶縁体を介して巻装した固定子巻線の巻線端末線を前記絶縁体に設けたピン端子に絡げて電気的に接続し、このピン端子と電気的に接続される導電部と、口出し線と、口出し線の先端に設けられた電気部品等と接続される外部部品接続用の導電部と、コンデンサおよびコンデンサの端子と接続されるコンデンサ接続用の導電部と、温度ヒューズおよび温度ヒューズ接続用の導電部と、電流ヒューズおよび電流ヒューズ接続用の導電部とを備えた端子台またはこれらのうち少なくとも一つは備えた端子台において、前記ピン端子と端子台の導電部との電気的接続かまたは端子台の導電部とコンデンサ、温度ヒューズ、電流ヒューズ等とのすべての電気的接続かまたは一部の個所の電気的接続が、溶接や半田付けによらず前記端子台または端子台の一部または電気部品、コンデンサ、温度ヒューズ、電流ヒューズのすべてまたはこれらの一部が装着固定されたハウジングＡを、固定子鉄芯が嵌合固定されたハウジングＢに組合せし組立てることにより、同時に完了する構成としたものである。
【００１０】
本発明によれば、端子台はハウジングＢとハウジングＡの組合せと同時にピン端子との組立と電気的接続が同時に完了するかまたは端子台の導電部とコンデンサ等との電気的接続が同時に完了する。そしてハウジングＢからハウジングＡを取り外すと同時に電気的接続が解放されるため、前記端子台の組立作業が簡略化されることになる。そして回転子組込時には端子台が固定子に装着されていないため前記端子台に設ける挿通孔は回転子の外径寸法より小径にすることができ、コンデンサ、温度ヒューズおよび導電体の配置スペースを拡大することができ、内蔵するコンデンサの容量範囲の拡大および端子台装着時の組立作業の容易化が可能なコンデンサ電動機の巻線端末処理用の端子台が得られ、また、コンデンサ等がハウジングＡに装着固定されているため、回転子組立て時コンデンサの配置、寸法に関係なく作業が可能となる。
