Description

【発明の属する技術分野】
本発明は、回転電機に組み込まれる固定子における巻線の結線構造に関するものである。
【０００２】
【従来の技術】
従来の回転電機の固定子は、図６ないし図８に示すように構成している。
図において、３０は回転電機で、この回転電機３０のフレーム３１と、回転子３２と、固定子３３とを主要構成要素としている。前記フレーム３１は、円筒状に構成し、両端部にブラケット３４、３５を取付けている。前記回転子３２は、ブラケット３４、３５に軸受３６、３７を取付け、この軸受３６、３７に支持された回転軸３８にヨーク３９が固定され、このヨーク３９の外周に永久磁石４０を取付けている。前記固定子３３は、磁性板を積層した固定子鉄心４１に固定子巻線４２を巻装して構成している。このように構成した回転電機３０の固定子巻線４２の巻き始め端および巻き終り端の接続は、図７および図８に示すような結線板ユニット４３で接続している。この結線板ユニット４３は、合成樹脂よりなる円板状のユニット本体４４の上面にＣ形状に形成し、一端に引き出し端子４５ａ、４６ａ、４７ａを有し、外周に複数個の前記固定子巻線４２の巻き始め端および巻き終わり端を接続する接続端子４５ｂ、４６ｂ、４７ｂを具えた相別用導電部材４５、４６、４７を設け、この相別用導電部材４５、４６、４７に絶縁部材４８、４９、５０を挟んで交互に積層して固定している。５１はユニット本体４４に取付けた共通導電部材である。
つぎに、固定子巻線の結線作業について説明をする。
ユニット本体４４上面に相別用導電部材４５を載置し、この相別用導電部材４５の上面に絶縁部材４８を載置する。つぎに、前記絶縁部材４８の上面に相別用導電部材４６を載置し、相別用導電部材４６の上面に絶縁部材４９載置する。さらに、絶縁部材４９の上面に相別用導電部材４７を載置し、この相別用導電部材４７の上面に絶縁部材５０を載置して交互に積層する。つぎに、前記ユニット本体４４の内側に共通用導電部材５１を固定して結線板ユニット４３を構成する。このように構成した結線板ユニット４３を固定子鉄心３３の一方側に対向させて配置し、固定子鉄心４１の固定子巻線４２の、例えば、Ｕ相の固定子巻線の一端を結線板ユニット４３の相別用導電部材４５の端子４５ｂに接続し、他端を結線板ユニット４３の共通用導電部材５１に接続する。このように、Ｖ相、Ｗ相の固定子巻線の一端を結線板ユニット４３の相別用導電部材４６、４７の端子４６ａ、４７ａに接続し、他端を結線板ユニット４３の共通用導電部材５１に接続して、固定子巻線の巻線端を結線板ユニット４３で結線して構成している。
【発明が解決しようとする課題】
ところが、従来の回転電機の固定子巻線４２は、固定子巻線４２の巻き始め端あるいは巻き終わり端の電線を突出させ、この突出した電線の端部を結線板ユニット４３の相別用導電部材４５、４６、４７の端子４５ｂ、４６ｂ、４７ｂ挿入して固定子巻線４２の端部と前記端子４５ｂ、４６ｂ、４７ｂとを半田付け等により固定していた。このため、狭い場所での固定子巻線４２の端部を相別用導電部材の端子４５ｂ、４６ｂ、４７ｂに挿入して接続しなければならず、固定子巻線４２の結線作業が煩雑であった。相別用導電部材をＣ字状に打ち抜いて構成しているため、材料の歩留りが悪い。
そこで、本発明は、コイルボビンに巻装した固定子巻線の端部相互を簡単に結線できるようにすることを目的とする。
【０００４】
【課題を解決するための手段】
上記問題点を解決するために、本発明は、固定子鉄心に取付けたコイルボビンに固定子巻線を巻装し、この固定子巻線の同相の各固定子巻線を、導体を介して連結した固定子をそなえた回転電機において、前記コイルボビンの軸方向傍らに結線板を配置するとともに、前記結線板内に相別用導電部材と共通用導電部材を配置する構成とし、前記結線板が、絶縁材より円板状に形成し、一方端面に円弧状の溝を径方向に複数個有して構成され、かつ、前記相別用導電部材と前記共通用導電部材が、帯状導体の側面にＵ字状の溝を有する端子片を設けて構成され、前記結線板の溝に相別用導電部材と共通用導電部材の帯状導体を挿入し、端子片を前記結線板より径方向に折り曲げて突出させている。
【０００５】
