Description

【０００１】
【産業上の利用分野】
本発明はボタン電池と称される円筒形薄型の電池を収納保持するボタン電池の保持方法に関するものである。
【０００２】
【従来の技術】
今日、一般にボタン電池と称される偏平型水銀電池などは、小型で電気容量が大きいため、家電製品その他各種電子機器の主電源として、又、商用電源を用いている機器の補助電源として多用されている。
このボタン電池は、図４に示すように、薄型の円柱形状に近い形状であって、外周ケースとなる側壁部１１及び底板部分を金属板で一体成形し、内部に電解液吸収材や電極用混合物を封入し、封口電極板１５で密封した構造とされている。
そして、外周の側壁部１１及び底板をプラス電極とし、封口電極板１５をマイナス電極として直径が７ｍｍ乃至１０ｍｍ程度にして、厚みを４ｍｍ程度とするものが多く、大型のボタン電池１０では、直径が２０ｍｍ前後にして厚みが８ｍｍ前後とされるものが使用されている。
このように、ボタン電池１０は、直径に対して厚みが薄く形成されているも、外周である側壁部１１が底部電極と一体とされているため、このボタン電池１０を収納する電池ケースでは、上ケース１Ａと下ケース１Ｂの結合により構成され、電池ケース１に設けられボタン電池１０を収納する収納穴２１の底部２３と側部２５とに弾性を備えた電極接点を位置させることが多く行われている。
【０００３】
即ち、図６乃至図８に示すように、挿入する電池１０の直径よりも僅かに大きな収納穴２１の底部２３に弾性を有する板状体の一端を回路基板５に取り付けて固定部３２として陰極切片３１を設け、又、収納穴２１の側部２５には弾性腕３６の一端を回路基板５に取り付け、弾性腕３６の他端を収納穴２１の内部に突出させる板状の陽極切片３５を取り付けることにより電池受けを形成し、この電池受けよりも直径の大きな蓋穴２９を収納穴の入口部分に形成し、この蓋穴２９に蓋体７０を取り付けるものである。
【０００４】
電池ケース１には、ボタン電池１０を収納するための蓋穴２９が形成され、図５及び図６に示すように、該蓋穴の円周上から内部に突出している短突片１ａ，１ａ及び該短突片から多少の隙間１ｅ，１ｅを介して突出している長突片１ｂ，１ｂ及びボタン電池を収納穴内に案内する案内突起１ｄ，１ｄが設けられている。
一方、蓋体７０には、蓋穴２９と略等しい形状を有する蓋本体７０ａ、蓋本体の背面側より延出する円筒形状の円筒体７０ｂ、該円筒体７０ｂから外周側から突出する係合突片７０ｃ，７０ｃ、係合突片７０ｃ，７０ｃ上に設けられた係合突部７０ｄ，７０ｄ、が設けられている。
【０００５】
この蓋穴２９に蓋体７０を取り付けるためには、まず蓋体の係合突片７０ｃ，７０ｃを蓋穴の短突片と長突片が存しない箇所から挿入する。この状態で蓋本体７０ａの表面に設けたスリット７０ｅにマイナスドライバやコイン等の治具により蓋体７０を図５（ａ）に示すＣＬＯＳＥの方向へ回転させると、短突片１ａ，１ａ及び長突片１ｂ，１ｂの上下を蓋本体７０ａと係合突片７０ｃ，７０ｃが包み込むように移動する。電池ケース表面に設けた目印１ｃと蓋本体の表面に設けた目印７０ｆが一致するまで蓋体を回転させると、係合突部７０ｄ，７０ｄが隙間１ｅ，１ｅに落ち込み蓋穴２９と蓋体７０との取り付けが完了する。
【０００６】
【発明が解決しようとする課題】
上記従来のボタン電池の保持方法では、ボタン電池１０と陽極切片３５との接触圧は、収納穴２１の大きさと陽極切片３５の弾性力で決定されるものであった。しかし製造段階において、精度良く製作管理しないと接触圧が変化してボタン電池からの電力の供給に支障をきたすという欠点があった。
また陽極切片３５に大きな外力が作用して変形してしまったときにも接触圧が変化してボタン電池からの電力の供給に支障をきたすといった欠点があった。
【０００７】
そこで本発明はかかる従来の問題に鑑みてなされたものであり、製造段階による多少の精度ずれや、外力等により陽極切片が多少の変形をおこしても、ボタン電池と陽極切片との接触圧を確保してボタン電池からの電力の供給に支障をきたしにくいボタン電池の保持方法を提供することにある。
【０００８】
【課題を解決するための手段】
上記課題を解決するために、蓋体を備えた上ケースと、下ケースの結合により構成された電池ケースと、電池ケース内の下ケース側に設けた収納穴に収納されるボタン電池を蓋体側である上ケース側へ付勢押圧する陰極切片と、ボタン電池を収納穴の側方へ付勢押圧する陽極切片とを備えたボタン電池の保持方法において、陽極切片と対向する収納穴周縁の位置に該収納穴の中心方向に突出して設けられボタン電池が収納されたときボタン電池の側壁部を陽極切片の方向に付勢押圧する少なくとも１つの弾性片を備えた。
【０００９】
即ち、陽極切片と対向する収納穴周縁部分に、収納穴の内方向に向かって突出する弾性片を設けたので、ボタン電池を収納穴に収納したときにボタン電池の側壁部が弾性片により陽極切片の存在する方向に付勢押圧され、製造段階による多少の精度ずれや、外力等により陽極切片が多少の変形をおこしても、ボタン電池と陽極切片との接触圧を確保してボタン電池からの電力を供給することができる。
【００１０】
【発明の実施の形態】
以下に本発明を図１から図３に基づいて詳細に説明する。図１は本実施の形態にかかるボタン電池の保持方法を示しボタン電池が収納される前の状態を示す断面図、図２は図１の状態におけるボタン電池の保持方法の平面図。図３は図１に示すボタン電池の保持方法によりボタン電池を収納したときの状態を示す断面図である。なお、前記従来例で示した構成要素と共通のものには同一の符号を付与している。
【００１１】
電池ケース１は上ケース１Ａと下ケース１Ｂの結合により構成され、上ケースの表面には挿入するボタン電池１０と蓋体７０を収納するための蓋穴２９が設けられ、蓋体７０はボタン電池１０の直径よりも僅かに大きく設定されている。電池ケース１は内部に回路基板５を収納しており、上ケースと下ケースの結合により保持されている。下ケースの内側に設けた浅溝状の底部２３に配置される弾性を有する板状体の一端を回路基板５に取り付けて固定部３２として陰極切片３１を設け、又、収納穴２１の側部２５には弾性腕３６の一端を回路基板５に取り付け、弾性腕３６の他端を収納穴２１の内部に突出させる板状の陽極切片３５を取り付けることにより電池受けを形成している。
【００１２】
下ケース１Ｂには図１及び図２に示すように、陽極切片３５と対向する収納穴２１の周縁部分に、収納穴２１の内方向に向かって突出する弾性片６が設けてある。さらに、弾性片６の先端部には傾斜面６ａが設けられている。
【００１３】
このような電池ケース１にボタン電池１０を収納穴２１に収納したいときは、ボタン電池を蓋穴２９から挿入する。すると前記ボタン電池の外周の側壁部１１と前記弾性片６に設けた傾斜面６ａが係合して、該弾性片６は収納穴の外方向に撓みながらボタン電池１０を前記収納穴２１に案内する。ボタン電池が収納穴内に収納されると、弾性片６は収納穴の内方向に撓みによってボタン電池の外周の側壁部１１を押圧して、図３に示すようにボタン電池１０は左右の両方向から陽極切片３５と弾性片６から圧縮されるように付勢押圧されるので、該陽極切片３５とボタン電池の側壁部１１との接触圧を強固に保持することが可能となる。
【００１４】
なお、ボタン電池１０を収納するための蓋穴２９と蓋体７０との係合する構造については従来と同様であり、即ち、蓋穴２９の円周上から内部に突出している短突片１ａ，１ａ及び該短突片から多少の隙間１ｅ，１ｅを介して突出している長突片１ｂ，１ｂ及びボタン電池を収納穴内に案内する案内突起１ｄ，１ｄが設けられている。一方、蓋体７０には、図５に示すように、蓋穴２９と略等しい形状を有する蓋本体７０ａ、蓋本体の背面側より延出する円筒形状の円筒体７０ｂ、該円筒体７０ｂから外周側から突出する係合突片７０ｃ，７０ｃ、係合突片７０ｃ，７０ｃ上に設けられた係合突部７０ｄ，７０ｄ、が設けられている。
【００１５】
この蓋穴２９に蓋体７０を取り付けるためには、まず蓋体の係合突片７０ｃ，７０ｃを蓋穴の短突片と長突片が存しない箇所から挿入する。この状態で蓋本体７０ａの表面に設けたスリット７０ｅにマイナスドライバやコイン等の治具により蓋体７０を図５（ａ）に示すＣＬＯＳＥの方向へ回転させると、短突片１ａ，１ａ及び長突片１ｂ，１ｂの上下を蓋本体７０ａと係合突片７０ｃ，７０ｃが包み込むように移動することにより取り付けが可能となる。
【００１６】
なお、本実施の形態では弾性片６を１つしか設けなかったが、１つに限らず複数設けてもよい。前記収納穴２１内の周縁に複数の弾性片６を設けることでボタン電池１０を振動等によりがたつきを防止することが可能となる。
【００１７】
【発明の効果】
以上説明したように本発明は、蓋体を備えた上ケースと、下ケースの結合により構成された電池ケースと、電池ケース内の下ケース側に設けた収納穴に収納されるボタン電池を蓋体側である上ケース側へ付勢押圧する陰極切片と、ボタン電池を収納穴の側方へ付勢押圧する陽極切片とを備えたボタン電池の保持方法において、陽極切片と対向する収納穴周縁の位置に収納穴の中心方向に突出して設けられボタン電池が収納されたときボタン電池の側壁部を陽極切片の方向に付勢押圧する少なくとも１つの弾性片を備えたので、ボタン電池を収納穴に収納したときにボタン電池の側壁部が弾性片により陽極切片の存在する方向に付勢押圧され、製造段階による多少の精度ずれや、外力等により陽極切片が多少の変形をおこしても、ボタン電池と陽極切片との接触圧を確保してボタン電池からの電力を供給することができる。

[Problems to be solved by the invention]
In the above conventional method for holding a button battery, the contact pressure between the button battery 10 and the anode piece 35 is determined by the size of the storage hole 21 and the elastic force of the anode piece 35. However, in the manufacturing stage, if the production control is not performed with high accuracy, the contact pressure changes and there is a drawback in that the power supply from the button battery is hindered.
Further, even when a large external force is applied to the anode piece 35 and it is deformed, there is a disadvantage that the contact pressure is changed and the power supply from the button battery is hindered.
[0007]
Therefore, the present invention has been made in view of such a conventional problem, and even if the anode piece is slightly deformed due to a slight deviation in accuracy due to the manufacturing stage or an external force, the contact pressure between the button cell and the anode piece is reduced. An object of the present invention is to provide a method for holding a button battery which is secured and hardly interferes with the power supply from the button battery .
