When it is installed onto the columnar terminal 30, the support pieces 20 can be engaged with a circular groove 31 in the columnar terminal 30, so that it can be fixed. Since the circular ring part 10 achieves elastic action, a circular insulator 53 positioned bellow the disc spring 1 can be securely fixed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、例えばアルミ電解コンデンサの端子に装着される絶縁体固定用の金具（皿状バネ）に関し、特に簡単に端子に装着して絶縁体を固定できる皿状バネの構造及びこれを使用した環状絶縁体の固定構造に関する。
【０００２】
【従来の技術】
従来、図５に示すような電解コンデンサ５０の蓋体５１に固定された端子５２に装着する環状の絶縁体５３を固定する場合、端子５２の周囲にねじ山５２ａを形成し、環状絶縁体５３を挿入した後にナット５４を締めることで環状絶縁体５３を固定していた。
すなわち、ナット５４を締め付けることにより、環状絶縁体５３の上部をナット５４下面で確実に押圧し、環状絶縁体５３のがたつきを抑えて固定することが行われていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記構造によれば、端子５２にねじ山５２ａを設ける必要があるとともに、固定に際してナット５４を締め付ける作業が必要なので、端子５２に装着された環状絶縁体５３の固定作業が煩雑になるという問題点があった。
【０００４】
本発明は上記実情に鑑みてなされたもので、端子に対して確実に固定でき且つ簡単な作業で装着可能な皿状バネの構造を提供することを目的としている。
【０００５】
【課題を解決するための手段】
上記目的を達成するため請求項１の発明は、一体的に形成される皿状バネ１であって、外周部１１に対して内周部１２が高位置に配置されるように断面が傾斜された皿状の環状リング部１０と、該環状リング部１０の内周部１２において高位置側に折曲して配設された複数の支持片２０と、を具備することを特徴としている。
【０００６】
請求項２の発明は、平面から突出して配置される円柱状端子３０に挿入配置された環状絶縁体５３を固定する固定構造であって、前記円柱状端子３０に環状溝３１を形成し、円柱状端子３０に対し請求項１の皿状バネ１の環状リング部１０を下方にして支持片２０が前記環状溝３１に嵌合するように配置することで、皿状バネ１の外周部１１で前記環状絶縁体５３を押圧して固定することを特徴としている。
【０００７】
本発明の皿状バネ１によれば、円柱状端子３０に装着するに際して、各支持片２０が円柱状端子３０の環状溝３１に嵌合することで固定でき、皿状の環状リング部１０が弾性作用を発揮することで皿状バネ１の下方に位置する環状絶縁体５３を確実に固定できる。
【０００８】
【発明の実施の形態】
本発明の実施の形態の一例としての皿状バネについて、図１及び図２を参照しながら説明する。図１は皿状バネの斜視説明図、図２（ａ）（ｂ）（ｃ）はそれぞれ皿状バネの平面説明図、Ａ−Ａ線断面説明図、Ｂ−Ｂ線断面説明図である。
【０００９】
皿状バネ１は、金属片をプレス加工して一体的に形成されるものであって、環状リング部１０と、この環状リング部１０の内側に形成された複数の支持片２０とから構成されている。
環状リング部１０は、その外周部１１を水平面に載置した場合に、外周部１１に対して内周部１２が高位置に配置されるように、断面が傾斜されて皿状を形成している。
【００１０】
複数の支持片２０は、環状リング部１０の内周部１２において等間隔に連設される各方形状片を、高位置側に折曲して傾斜させて形成するものであり、内周部１２の互に対向する位置に三対配設されている。そして、支持片２０の先端部２１を含む円周（点線で表示）２２の直径は、皿状バネ１が装着される後述の円柱状端子３０の直径と略同じ長さで形成されている。
【００１１】
上記例では、環状リング部１０の内周部１２に三対で合計６個の支持片２０をそれぞれ形成したが、支持片２０の個数及び形成位置は適宜設計すればよい。
【００１２】
次に、上記構造の皿状バネ１を使用して環状絶縁体５３を固定する固定構造について、図３を参照しながら説明する。この皿状バネ１は、電解コンデンサ５０や自動車に掲載されるバッテリーの円柱状端子３０に装着される環状絶縁体５３の固定用として使用される。
【００１３】
すなわち、円柱状の電解コンデンサ５０の上部蓋体５１に立設されたニつの円柱状端子３０に対して、環状絶縁体５３が装着され、その上から環状リング部１０が下になるように皿状バネ１が挿入されている。円柱状端子３０の中央部の側面には環状溝部３１が形成され、この環状溝部３１に各支持片２０の先端部２１が嵌合配置するようになっている。
この構造の皿状バネ１によれば、環状溝部３１に各支持片２０の先端部２１が嵌合配置することで、電解コンデンサ５０の円柱状端子３０での固定に必要な抜け荷重（１９６Ｎ以上）を得ることができる。
【００１４】
続いて、具体的な装着手順について、図４を参照しながら説明する。
先ず、電解コンデンサ５０の円柱状端子３０に対して、環状絶縁体５３を挿入して配置する。次に、環状絶縁体５３の上から環状リング部１０が下になるように皿状バネ１を挿入する。この状態では、皿状バネ１の支持片２０が環状溝３１より高い場所に位置しており、皿状バネ１が固定にされていない。したがってこの状態で治具４０を使用することにより、皿状バネ１を押し込む作業が必要となる。
【００１５】
すなわち、有底円筒形状の治具４０の開口側を下にし、周囲壁４１の端部で皿状バネ１の支持片２０の折曲部付近を押圧し、環状リング部１０のバネ力に抗して皿状バネ１を圧縮変形させることで、支持片２０の先端部２１が環状溝部３１に嵌合し、円柱状端子３０への皿状バネ１の固定を確実にする。この状態では、支持片２０の先端部２１が環状溝部３１に嵌合することにより、環状リング１０の外周部１１に下方向への押圧力が作用し、この力により環状絶縁体５３が押圧され、がたつきが生じることなく固定される。
【００１６】
【発明の効果】
本発明の皿状バネによれば、円柱状端子に装着するに際して、各支持片が円柱状端子の環状溝に嵌合することで固定でき、皿状の環状リング部が弾性作用を発揮することで皿状バネの下方に位置する環状絶縁体を確実に固定することができる。
また、本発明の皿状バネによれば、嵌合作業で固定できるので、従来例のように締結作業を必要とせず、簡単な作業で環状絶縁体を確実に固定できる。

The plurality of support pieces 20 are formed by bending and inclining rectangular pieces continuously arranged at equal intervals in the inner peripheral portion 12 of the annular ring portion 10 toward a higher position. Twelve pairs are provided at 12 opposite positions. The diameter of a circumference (indicated by a dotted line) 22 including the distal end portion 21 of the support piece 20 is formed to be substantially the same as the diameter of a cylindrical terminal 30 to which the dish spring 1 is mounted, which will be described later.
[0011]
In the above example, a total of six support pieces 20 are formed in three pairs on the inner peripheral part 12 of the annular ring part 10, but the number and the formation position of the support pieces 20 may be appropriately designed.
