Description

【０００１】
【発明の属する技術分野】
本発明は、電池アダプタケースに関する。
【０００２】
【従来の技術】
一般に、電気製品は、その電池収納部に定められた規格電池を充填可能としている。しかし、電気製品は、その規格電池より小さい小型電池を充填できないため、以下のような問題が生ずる。
【０００３】
即ち、電気製品が、例えば携帯電子手帳である場合、それに使用される電池の電力が、音を発生させる程度の電力があっても、電気製品の主電源の電力に満たなければ、その電池は、使用できなくなり、無駄なものとなる。
【０００４】
そこで、従来、実用新案登録番号第3039798 号公報に示されるように、電気製品の電池収納部内に充填されて、該電池収納部に定められた規格電池より小さい小型電池を使用可能とする電池アダプタケースが考案され、上記使用済みの電池を他の低級なもの（時計、ラジオ）に使用することができるようになり、省資源や環境保護に貢献できるようになった。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来の電池アダプタケースは、規格電池と同一形状に形成されると共に小型電池を内蔵するケース本体と、ケース本体の端部に装着される蓋本体と、を備えており、ケース本体と蓋本体とは別部品となり、部品数が多くなり、故障し易かった。また、蓋本体をケース本体にねじ込んで装着する必要があり、取り付けに手間がかかっていた。
【０００６】
さらに、従来の電池アダプタケースは、規格電池より１ランク下の寸法を有する小型電池しか内蔵できず（例えば、単１電池と同一形状の電池アダプタケースは、単２電池のみ内蔵可能）、規格電池より２ランク下の小型電池（例えば、単３電池）を内蔵する場合は、規格電池より１ランク下の小型電池（例えば、単２電池）と同一形状の電池アダプタケースが必要となり（即ち、電池アダプタケースを幾重に被覆していく必要があり）、無駄が多かった。
【０００７】
そこで、本発明は、省資源や環境保護に貢献できると共に、電池の取り付け・取り外しが容易に行なえ、製作が容易で、コストダウンが図れ、部品数が少なく、無駄のない電池アダプタケースを提供することを目的とする。
【０００８】
【課題を解決するための手段】
上述の目的を達成するために、本発明に係る電池アダプタケースは、電気製品の電池収納部内に充填されて、該電池収納部に定められた規格電池より小さい小型電池を使用可能とし、上記規格電池が単２電池で、上記小型電池が単３電池である電池アダプタケースであって、上記規格電池の形状と略同一に形成されると共に上記小型電池を内蔵可能とする中空円柱状のケース本体を備え、上記ケース本体は、該ケース本体の軸心上で２分した中空半円柱状の第１半体と中空半円柱状の第２半体とを備え、さらに、上記第１半体の長手方向一側辺と上記第２半体の長手方向一側辺を連結して揺動自在に開閉させる薄肉弯曲自在片部から成るヒンジ部を有し、上記第１半体及び上記第２半体は、夫々、長手方向他側辺側の外周面に形成される窪部と、内面に上記ケース本体の軸心方向に並設されると共に内径方向に突設された複数の円弧状の支持板と、長手方向の前後端面に形成される半円形状の切欠部と、を有し、上記第１半体の上記窪部に係止突部を有する弾性舌片が突設されると共に、上記第２半体の上記窪部に上記係止突部と係脱可能な係止爪部が突設され、上記ケース本体は、プラスチック一体成型品から成ると共に、上記小型電池が内蔵されていることを目視可能な透明樹脂から成り、上記第１半体と上記第２半体を閉じた閉状態で上記第１半体及び上記第２半体の前後の上記切欠部にて形成される円形状の前後の孔部の直径を同一に設定し、上記ケース本体に上記小型電池を内蔵した閉状態において、上記支持板にて上記小型電池の軸心を上記ケース本体の軸心に略一致させると共に、上記第１半体及び上記第２半体の前後端面と上記支持板とで上記小型電池を圧接状に挟持して該小型電池が上記ケース本体に対して軸心方向及び径方向に位置ズレするのを抑制するように構成したものである。
【０００９】
また、電気製品の電池収納部内に充填されて、該電池収納部に定められた規格電池より小さい小型電池を使用可能とし、上記規格電池が単１電池で、上記小型電池が単３電池である電池アダプタケースであって、上記規格電池の形状と略同一に形成されると共に内蔵される上記小型電池の陽極及び陰極に接触する陽電極具及び陰電極具が取着される中空円柱状のケース本体を備え、上記陽電極具は、外鍔部を有する円柱状の導体から成り、上記陰電極具は、導体の板バネ部と、該板バネ部が取着される樹脂製の取付板部と、から成り、上記ケース本体は、該ケース本体の軸心上で２分した中空半円柱状の第１半体と中空半円柱状の第２半体とを備え、さらに、上記第１半体の長手方向一側辺と上記第２半体の長手方向一側辺を連結して揺動自在に開閉させる薄肉弯曲自在片部から成るヒンジ部を有し、上記第１半体及び上記第２半体は、夫々、長手方向他側辺側の外周面に形成される窪部と、内面に上記ケース本体の軸心方向に並設されると共に内径方向に突設された複数の円弧状の支持板と、を有し、上記第１半体の上記窪部に係止突部を有する弾性舌片が突設されると共に、上記第２半体の上記窪部に上記係止突部と係脱可能な係止爪部が突設され、上記第２半体は、前方端面に形成される半円突部と、該前方端面乃至上記半円突部に形成された上記陽電極具の挿通用円形孔部と、前方端面内側に設けられ上記陽電極具の外鍔部を係止する支持片と、後方端面内側に設けられ上記陰電極具の上記取付板部が取着される囲い壁部と、を有し、上記第１半体は、前方端面に形成されると共に上記第１半体と上記第２半体を閉じた閉状態において上記半円突部が嵌合する半円状の切欠部と、前方端面内側に設けられ上記閉状態において上記陽電極具の外鍔部を係止する支持片と、後方端面内側に設けられ上記閉状態において上記陰電極具の上記取付板部が差し込まれる囲い壁部と、を有し、上記ケース本体は、プラスチック一体成型品から成ると共に、上記小型電池が内蔵されていることを目視可能な透明樹脂から成り、上記ケース本体に上記小型電池を内蔵した閉状態において、上記支持板にて上記小型電池の軸心を上記ケース本体の軸心に略一致させると共に、上記陽電極具と上記陰電極具と上記支持板とで上記小型電池を圧接状に挟持して該小型電池が上記ケース本体に対して軸心方向及び径方向に位置ズレするのを抑制するように構成したものである。
【００１０】
【発明の実施の形態】
以下、実施の形態を示す図面に基づき、本発明を詳説する。
【００１１】
図１の斜視図及び図２の構成説明図は、本発明に係る電池アダプタケースの実施の一形態を示し、本ケースは、一側辺側のヒンジ部４廻りに揺動して開閉可能とする第１半体１・第２半体２からなるケース本体３を備えたものである。
【００１２】
本ケースは、（図示省略の）電気製品の電池収納部内に充填されて、該電池収納部に定められた規格電池より小さい小型電池を使用可能とするものである。
【００１３】
ケース本体３は、規格電池の形状と略同一の円筒状に形成され、（図１の仮想線に示す）小型電池20を内蔵可能とする。特に、規格電池は単２電池であり、小型電池は単３電池である。なお、ケース本体３は、透明樹脂から成る。外から（目視で）小型電池20が内蔵されているかを容易に確認できる。
【００１４】
また、ケース本体３は、中空の円柱体を軸心上で２分した第１半体１と第２半体２とから成り、第１半体１と第２半体２は、それらの（軸心方向の）一側辺側の両端側（前後）に付設された２つのヒンジ部４，４廻りに揺動して開閉可能（自在）となる。
【００１５】
具体的に述べると、第１半体１及び第２半体２は、夫々、中空の半円柱状に形成され、その軸心方向の両端にある半円形状の端面（その長手方向の前後端面）に、半円形状の切欠部５，５が設けられている。なお、図１の仮想線に示すように、内蔵される小型電池20の陽極20ａに対応する側を前方向とし、陰極20ｂに対応する側を後方向とする。
【００１６】
そして、第１半体１と第２半体２を閉じた際、（図５に示すように、）第１半体１の切欠部５と第２半体２の切欠部５にて円形状の孔部11が形成される。なお、ケース本体３の前後に形成される孔部11，11の直径は同一である。
【００１７】
なお、第１半体１と第２半体２とヒンジ部４はプラスチック一体成型品から成り、ヒンジ部４は薄肉弯曲自在片部から成り、第１半体１と第２半体２の閉状態では、ヒンジ部４は、弾性変形しており、第１半体１と第２半体２を開く方向に（若干に）弾発付勢している状態にある。
【００１８】
さらに、第１半体１及び第２半体２は、夫々、他側辺側の外周面に窪部６が設けられ、第１半体１の窪部６には、弾性舌片７が一体状に突設され、第２半体２の窪部６には、係止爪部９が一体状に突設され、弾性舌片７の係止突部８と係止爪部９との係止により、第１半体１と第２半体２との閉状態を維持することができる。このように、弾性舌片７及び係止爪部９を窪部６に設けているため、本ケースを電気製品の電池収納部に（引っ掛けずに）円滑に充填することができ、また、（後述するように）係止突部８を係止爪部９から容易に離脱させることができる。
【００１９】
また、ケース本体３の内面（内側）には、ケース本体３の軸心上に小型電池20を保持する支持板10…が設けられている。即ち、第１半体１及び第２半体２の内面には、夫々、複数個（本実施の形態では４個）の円弧状の支持板10…が、軸心方向に配設され、ケース本体３に内蔵される小型電池20の軸心を、ケース本体３の軸心に略一致させることができる。
【００２０】
次に、上述のように構成されたケース本体３に小型電池20を内蔵する方法を説明する。即ち、図３に示すように、第１半体１と第２半体２の開状態において、第２半体２の支持板10…（の内周側）に、小型電池20を載置する。この際、小型電池20の陽極20ａ及び陰極20ｂは、夫々、第２半体２の前後の切欠部５，５から（軸心方向）外方へ（若干）突出状に配設される。要するに、ケース本体３の軸心方向の長さ寸法は、小型電池20の軸心方向の長さ寸法に比べて、若干短く（乃至略同一に）設定されている。
【００２１】
そして、図４（Ａ）に示すように、第１半体１を（第２半体２に接近させるように）閉じていくと、図４（Ｂ）に示すように、第１半体１の弾性舌片７の係止突部８が、第２半体２の係止爪部９に当接するが、弾性舌片７の弾性変形にて、係止突部８が、係止爪部９を乗り越えて、図４（Ｃ）に示すように、弾性舌片７（係止突部８）が係止爪部９に係止した第１半体１と第２半体２の閉状態となる。なお、図４において、小型電池20の断面を簡略している。
【００２２】
また、この閉状態では、小型電池20は第１半体１及び第２半体２の支持板10…に挾持（位置決め）されて、小型電池20の軸心とケース本体３の軸心が略一致するため、本ケースを電気製品の電池収納部内に正確に充填することができる。
【００２３】
さらに、小型電池20は、第１半体１及び第２半体２の支持板10…と、第１半体１及び第２半体２の前後端面と、に圧接状に挾持（位置決め）されているため、小型電池20がケース本体３に対して（径方向及び軸心方向に）容易に位置ずれしないように抑制される。
【００２４】
なお、閉状態から開状態にするには、弾性舌片７を弾性変形させて係止突部８を係止爪部９から離脱させると、ヒンジ部４の弾発付勢により第１半体１が揺動して、容易に開状態となる。この際、窪部６に指を掛けることができ、容易にケース本体３を開けることができる。
【００２５】
そして、小型電池20を内蔵したケース本体３において、図５（Ａ）に示すように、後ろの孔部11から小型電池20の陰極20ｂが臨み、図５（Ｂ）に示すように、前の孔部11から小型電池20の陽極20ａが臨んでいる。なお、図５（Ａ）に示すように、後ろの孔部11の直径寸法が、小型電池20の陰極20ｂの直径寸法よりも小さく（乃至略同一に）設定されるのが望ましく、小型電池20のショートを防止することができる。
【００２６】
次に、図６に本発明の他の実施の形態を示し、図２と比較すると、次の構成が相違する。なお、図２と同一符号は、同一構成であるので、その説明を省略する。
【００２７】
即ち、第２半体２の前方端面に半円突部12が設けられ、第１半体１の前方端面に半円形状の切欠部13が設けられ、ケース本体３を閉じた際に、半円突部12と切欠部13とが嵌合するように構成されている。また、第２半体２の前方端面乃至半円突部12に円形孔部14が貫設されている。さらに、第１半体１と第２半体２を閉じた際、（図９に示すように、）第１半体１の切欠部５と第２半体２の切欠部５にて形成される（後方の）孔部11の直径寸法は、（前方の）円形孔部14の直径寸法よりも大きく設定されている。なお、ケース本体３は、単１電池（規格電池）の形状と略同一に形成され、小型電池は単３電池である。
【００２８】
しかも、図７に示すように、ケース本体３には、内蔵される小型電池20の陽極20ａ及び陰極20ｂに接触する陽電極具15及び陰電極具16が付設されている。即ち、（導体である）陽電極具15が、第２半体２の前方の円形孔部14に挿通され、（導体である）陰電極具16が、第２半体２の切欠部５に嵌め込まれる。
【００２９】
具体的に述べると、陽電極具15は、一端面に外鍔部を有する円柱体であり、該外鍔部が、第２半体２の前方端面内側に設けられた支持片21の段付き部に係止状に載置される。そして、ケース本体３の閉状態にて、陽電極具15の外鍔部が、第１半体１及び第２半体２の前方端面内側に設けられた支持片21，21に係止状に挾持されるため、陽電極具15がケース本体３に対して（径方向及び軸心方向に）容易に位置ずれしないように抑制される。
【００３０】
また、支持片21（の段付き部）は、（後述するように）小型電池20をケース本体３に内蔵する際に、小型電池20の陰極20ｂを陽電極具15側に誤って逆に配設しても、陰極20ｂが陽電極具15に接触しない（離間する）ように設定されており、逆に配設された小型電池20の通電が防止される。言い換えると、支持片21（段付き部）は、小型電池20をケース本体３に内蔵する際に、小型電池20の陽極20ａのみが陽電極具15に接触するように設定されている。
【００３１】
また、陰電極具16は、図８に示すように、（導体である）板バネ部17と、板バネ部17が（一体状に）取り付けられる（樹脂製の）取付板部18と、から成る。
【００３２】
板バネ部17は、小型電池20の陰極20ｂと接触する帯状舌片17ａと、ケース本体３が内蔵される電気製品の電極具と接触する平板17ｂと、を有し、帯状舌片17ａの一端が平板17ｂの端縁に連設されて、帯状舌片17ａの他端が平板17ｂに近接するように、帯状舌片17ａの一端部が「く」の字状に折り曲げられた形状をしており、帯状舌片17ａの一端部が弾性変形するように構成されている。
【００３３】
取付板部18は、矩形板の一辺（上方側）に半円形板が連設した形状であり、半円形板の上方に係止突片23が突設され、矩形板の他辺（下方側）に２本の係止脚部24，24が突設されている。
【００３４】
そして、取付板部18の一面に、板バネ部17の帯状舌片17ａが対応し、取付板部18の他面に、板バネ部17の平板17ｂが対応するように、板バネ部17が取付板部18に取り付けられる。
【００３５】
そして、板バネ部17が取り付けられた取付板部18は、第２半体２の後方端面内側に設けられた囲い壁部26（図６参照）の内部に、取付板部18の係止脚部24，24を差し込むことで、固定状に取り付けられる。そして、ケース本体３の閉状態にて、取付板部18の係止突片23が、第１半体１の後方端面内側に設けられた囲い壁部27（図６参照）の内部に、差し込まれて、陰電極具16がケース本体３に対して（径方向及び軸心方向に）容易に位置ずれしないように抑制される。
【００３６】
このように、板バネ部17を取付板部18に取り付けたため、板バネ部17の（鋭利な）端縁が、取付板部18に覆われて、安全なものとなる。また、ケース本体３を閉じるときに生じる衝撃が板バネ部17に直接に伝わらず、耐久性に優れたものとなる。さらに、板バネ部17を、取付板部18を介して、ケース本体３に確実に取付けることができる。
【００３７】
そして、小型電池20をケース本体３に内蔵するには、小型電池20を、陽電極具15と陰電極具16の間に配設すると共に第２半体２の支持板10，10に載置する。この際、陰電極具16の板バネ部17の弾発付勢にて、小型電池20は、陽電極具15と陰電極具16にて弾発的に挾持されている。その後、ケース本体３の閉状態にて（図４参照）、小型電池20は、第１半体１及び第２半体２の支持板10…と、陽電極具15と陰電極具16と、に圧接状に挾持（位置決め）されているため、小型電池20がケース本体３に対して（径方向及び軸心方向に）容易に位置ずれしないように抑制される。
【００３８】
また、小型電池20を内蔵したケース本体３において、図９（Ａ）に示すように、後方の孔部11から陰電極具16（板バネ部17の平板17ｂ）が臨み、図９（Ｂ）に示すように、前方の円形孔部14から陽電極具15が臨んでいる。
【００３９】
なお、本発明は上述の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で設計変更可能である。
【００４０】
【発明の効果】
本発明は上述の如く構成されるので、次に記載する効果を奏する。
【００４１】
（請求項１、２によれば、）ケース本体３が、規格電池の形状と略同一に形成されると共に小型電池20を内蔵可能とするため、ある（高級な）電気製品（例えば、携帯電子手帳）で使用済みとなった電池を、他の（低級な）電気製品（例えば、時計やラジオ）に使用することができるようになり、省資源や環境保護に貢献できる。また、小型電池20のみを必要とするため、小型電池20をまとめて安く購入できる。
【００４２】
また、ケース本体３が、一側辺側のヒンジ部４廻りに揺動して開閉可能とする第１半体１・第２半体２からなるため、ケース本体を簡単な構造とすることができ、製作が容易で、コストダウンが図れ、部品数が少なく、しかも、小型電池20のケース本体３への取り付け・取り外しが容易に行なえ、無駄のないものとすることができる。
【００４３】
また、小型電池20が単３電池であるため、単３電池のみを必要とするため、単３電池をまとめて安く購入できる。
【００４４】
また、ケース本体３を、プラスチック一体成型品にて、容易に製作できると共に、製作コストを抑制できる。また、ヒンジ部４を簡単な構造とすることができ、故障の少ないものとなる。
【００４５】
また、ケース本体３の内面には、ケース本体３の軸心上に小型電池20を保持する支持板10が設けられているため、小型電池20がケース本体３に対して（径方向に）容易に位置ずれしないように抑制され、本ケースを電気製品の電池収納部内に正確に充填することができる。

[0011]
A perspective view of FIG. 1 and an explanatory diagram of a configuration of FIG. 2 show an embodiment of a battery adapter case according to the present invention, and the case can swing around a hinge portion 4 on one side and can be opened and closed. A case main body 3 composed of a first half 1 and a second half 2 is provided.
[0012]
The case is filled in a battery housing part of an electric product (not shown), and a small battery smaller than a standard battery defined in the battery housing part can be used.
[0013]
The case body 3 is formed in a cylindrical shape that is substantially the same as the shape of the standard battery, and can accommodate a small battery 20 (shown in phantom lines in FIG. 1). In particular, the standard battery is an AA battery, and the small battery is an AA battery. In addition, the case body 3, Ru from transparent resin formed. It can be easily confirmed from the outside (visually) whether the small battery 20 is incorporated.
[0014]
The case body 3 is composed of a first half 1 and a second half 2 obtained by dividing a hollow cylindrical body into two on the axis, and the first half 1 and the second half 2 are those ( It swings around two hinges 4 and 4 attached to both end sides (front and rear) on one side side (in the axial direction) and can be opened and closed (freely).
[0015]
More specifically, each of the first half 1 and the second half 2 is formed in a hollow semi-cylindrical shape, and has semicircular end faces at both ends in the axial direction (front and rear end faces in the longitudinal direction). ) Are provided with semicircular cutouts 5 and 5. As shown by the phantom lines in FIG. 1, the side corresponding to the anode 20a of the built-in small battery 20 is the forward direction, and the side corresponding to the cathode 20b is the backward direction.
[0016]
When the first half 1 and the second half 2 are closed, as shown in FIG. 5, the cutout 5 of the first half 1 and the cutout 5 of the second half 2 are circular. The hole 11 is formed. In addition, the diameters of the holes 11 and 11 formed before and after the case body 3 are the same.
[0017]
The first half 1, the second half 2, and the hinge part 4 are made of an integrally molded plastic part, and the hinge part 4 is made of a thin-walled bendable piece, and the first half 1 and the second half 2 are closed. In the state, the hinge part 4 is elastically deformed and is in a state of being elastically biased in the direction of opening the first half 1 and the second half 2 (slightly).
[0018]
Further, the first half 1 and the second half 2 are each provided with a recess 6 on the outer peripheral surface on the other side, and the elastic tongue 7 is integrated with the recess 6 of the first half 1. In the recess 6 of the second half 2, a locking claw 9 is integrally projected, and the engagement between the locking projection 8 of the elastic tongue 7 and the locking claw 9. The closed state of the first half 1 and the second half 2 can be maintained by stopping. Thus, since the elastic tongue piece 7 and the locking claw portion 9 are provided in the recess portion 6, the case can be smoothly filled into the battery housing portion of the electric product (without hooking), and ( The locking projection 8 can be easily detached from the locking claw 9 as will be described later.
[0019]
Further, on the inner surface (inner side) of the case body 3, support plates 10 for holding the small batteries 20 are provided on the axis of the case body 3. That is, on the inner surfaces of the first half 1 and the second half 2, a plurality of (four in the present embodiment) arcuate support plates 10 are arranged in the axial direction, and the case The axis of the small battery 20 built in the main body 3 can be made substantially coincident with the axis of the case main body 3.
[0020]
Next, a method for incorporating the small battery 20 in the case body 3 configured as described above will be described. That is, as shown in FIG. 3, in the open state of the first half 1 and the second half 2, the small battery 20 is placed on the support plate 10 (inner circumference side) of the second half 2. . At this time, the anode 20a and the cathode 20b of the small battery 20 are disposed so as to protrude outward (slightly) from the front and rear cutouts 5 and 5 of the second half 2 (in the axial direction). In short, the length dimension in the axial direction of the case body 3 is set slightly shorter (or substantially the same) than the length dimension in the axial direction of the small battery 20.
[0021]
Then, as shown in FIG. 4 (A), when the first half 1 is closed (so as to approach the second half 2), as shown in FIG. 4 (B), the first half 1 The locking projection 8 of the elastic tongue piece 7 abuts on the locking claw portion 9 of the second half 2. The elastic projection 7 causes the locking projection 8 to be locked to the locking claw portion by elastic deformation of the elastic tongue piece 7. As shown in FIG. 4 (C), the closed state of the first half 1 and the second half 2 in which the elastic tongue 7 (locking protrusion 8) is locked to the locking claw 9 is obtained. It becomes. In FIG. 4, the cross section of the small battery 20 is simplified.
[0022]
In this closed state, the small battery 20 is held (positioned) by the support plates 10 of the first half 1 and the second half 2 so that the axis of the small battery 20 and the axis of the case main body 3 are substantially the same. Since it corresponds, this case can be correctly filled in the battery accommodating part of an electric product.

Further, the small battery 20 is clamped (positioned) in a pressure contact manner between the support plates 10 of the first half 1 and the second half 2 and the front and rear end surfaces of the first half 1 and the second half 2. Therefore, the small battery 20 is restrained from being easily displaced with respect to the case body 3 (in the radial direction and the axial direction).
[0024]
In order to change from the closed state to the open state, when the elastic tongue piece 7 is elastically deformed and the locking projection 8 is detached from the locking claw portion 9, the first half body is caused by the elastic urging force of the hinge portion 4. 1 swings and is easily opened. At this time, a finger can be put on the recess 6 and the case body 3 can be easily opened.
[0025]
Then, in the case body 3 incorporating the small battery 20, as shown in FIG. 5A, the cathode 20b of the small battery 20 faces through the rear hole 11, and as shown in FIG. The anode 20a of the small battery 20 faces from the hole 11. As shown in FIG. 5A, it is desirable that the diameter dimension of the rear hole 11 is set smaller (or substantially the same) than the diameter dimension of the cathode 20b of the small battery 20, and the small battery 20 Can be prevented.
[0026]
Next, FIG. 6 shows another embodiment of the present invention, which is different from FIG. 2 in the following configuration. Note that the same reference numerals as those in FIG.
[0027]
That is, a semicircular protrusion 12 is provided on the front end surface of the second half 2, and a semicircular cutout 13 is provided on the front end surface of the first half 1. The circular protrusion 12 and the notch 13 are configured to be fitted. In addition, a circular hole 14 is provided through the front end surface or the semicircular protrusion 12 of the second half 2. Further, when the first half 1 and the second half 2 are closed, as shown in FIG. 9, the first half 1 and the second half 2 are formed with the notch 5 and the notch 5 of the second half 2. The diameter dimension of the (rear) hole 11 is set larger than the diameter dimension of the (forward) circular hole 14. In addition, the case main body 3 is formed in substantially the same shape as an AA battery (standard battery), and the small battery is an AA battery.

In addition, as shown in FIG. 7, the case body 3 is provided with a positive electrode tool 15 and a negative electrode tool 16 which are in contact with the anode 20 a and the cathode 20 b of the small battery 20 incorporated therein. That is, the positive electrode tool 15 (which is a conductor) is inserted into the circular hole 14 in front of the second half 2, and the negative electrode tool 16 (which is a conductor) is inserted into the notch 5 of the second half 2. It is inserted.
[0029]
Specifically, the positive electrode tool 15 is a cylindrical body having an outer flange portion on one end surface, and the outer flange portion is stepped on the support piece 21 provided inside the front end surface of the second half body 2. It is placed in a locking manner on the part. In the closed state of the case body 3, the outer flange portion of the positive electrode tool 15 is engaged with the support pieces 21, 21 provided inside the front end surfaces of the first half 1 and the second half 2. Since it is held, the positive electrode tool 15 is restrained from being easily displaced with respect to the case body 3 (in the radial direction and the axial direction).
[0030]
Further, the support piece 21 (the stepped portion thereof) is arranged so that the cathode 20b of the small battery 20 is mistakenly placed on the positive electrode 15 side when the small battery 20 is incorporated in the case body 3 (as will be described later). Even if it is provided, the cathode 20b is set so as not to contact (separate) the positive electrode tool 15, and energization of the small battery 20 arranged in reverse is prevented. In other words, the support piece 21 (stepped portion) is set so that only the anode 20 a of the small battery 20 contacts the positive electrode tool 15 when the small battery 20 is built in the case body 3.
[0031]
Further, as shown in FIG. 8, the negative electrode device 16 includes a leaf spring portion 17 (which is a conductor) and a mounting plate portion 18 ( made of resin) to which the leaf spring portion 17 is attached (integrally). Become.
[0032]
The leaf spring portion 17 has a strip-like tongue piece 17a that comes into contact with the cathode 20b of the small battery 20, and a flat plate 17b that comes into contact with an electrode device of an electrical product in which the case body 3 is built, and one end of the strip-like tongue piece 17a. Is connected to the edge of the flat plate 17b, and one end of the strip-like tongue piece 17a is bent into a "<" shape so that the other end of the strip-like tongue piece 17a is close to the flat plate 17b. And one end of the belt-like tongue piece 17a is elastically deformed.
[0033]
The mounting plate portion 18 has a shape in which a semicircular plate is continuously provided on one side (upper side) of the rectangular plate, and a locking protrusion 23 protrudes above the semicircular plate, and the other side (lower side) of the rectangular plate. ) Are provided with two locking leg portions 24,24.
[0034]
Then, the leaf spring portion 17 corresponds to one surface of the attachment plate portion 18 corresponding to the strip-like tongue piece 17a of the leaf spring portion 17, and the other surface of the attachment plate portion 18 corresponds to the flat plate 17b of the leaf spring portion 17. It is attached to the mounting plate portion 18.
[0035]
Then, the mounting plate portion 18 to which the leaf spring portion 17 is attached has a locking leg of the mounting plate portion 18 inside the surrounding wall portion 26 (see FIG. 6) provided inside the rear end face of the second half 2. By inserting the parts 24, 24, it can be fixedly attached. Then, in the closed state of the case body 3, the locking projection piece 23 of the mounting plate portion 18 is inserted into the surrounding wall portion 27 (see FIG. 6) provided on the inner side of the rear end face of the first half 1. Thus, the negative electrode device 16 is restrained from being easily displaced with respect to the case body 3 (in the radial direction and the axial direction).
[0036]
Since the leaf spring portion 17 is attached to the attachment plate portion 18 in this way, the (sharp) edge of the leaf spring portion 17 is covered with the attachment plate portion 18 and becomes safe. Further, the impact generated when the case body 3 is closed is not directly transmitted to the leaf spring portion 17, and the durability is excellent. Further, the leaf spring portion 17 can be reliably attached to the case body 3 via the attachment plate portion 18.
[0037]
In order to incorporate the small battery 20 in the case body 3, the small battery 20 is disposed between the positive electrode tool 15 and the negative electrode tool 16 and mounted on the support plates 10 and 10 of the second half 2. To do. At this time, the small battery 20 is elastically held between the positive electrode tool 15 and the negative electrode tool 16 by the elastic biasing force of the leaf spring portion 17 of the negative electrode tool 16. After that, in the closed state of the case body 3 (see FIG. 4), the small battery 20 includes a support plate 10 of the first half 1 and the second half 2, a positive electrode tool 15, a negative electrode tool 16, Therefore, the small battery 20 is restrained from being easily displaced with respect to the case body 3 (in the radial direction and the axial direction).
[0038]
Further, in the case main body 3 incorporating the small battery 20, as shown in FIG. 9A, the negative electrode tool 16 (the flat plate 17b of the leaf spring portion 17) faces the rear hole 11, and FIG. As shown, the positive electrode tool 15 faces the front circular hole portion 14.
[0039]
Note that the present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention.
[0040]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0041]
(According to claims 1 and 2 ), the case body 3 is formed to be substantially the same as the shape of the standard battery and to be able to incorporate the small battery 20, so that a certain (high-grade) electric product (for example, portable electronic device) Batteries that have been used in the notebook can be used for other (lower) electrical products (for example, watches and radios), contributing to resource saving and environmental protection. Further, since only the small battery 20 is required, the small batteries 20 can be purchased together at a low price.
[0042]
In addition, since the case body 3 is composed of the first half 1 and the second half 2 that swing around the hinge portion 4 on one side and can be opened and closed, the case body can have a simple structure. It can be manufactured easily, the cost can be reduced, the number of parts is small, and the small battery 20 can be easily attached to and detached from the case main body 3 so that there is no waste.
[0043]
Moreover, since the small battery 20 is an AA battery, only an AA battery is required, and therefore AA batteries can be purchased together at a low price.
[0044]
In addition, the case body 3 can be easily manufactured with a plastic integrated molded product, and the manufacturing cost can be suppressed. Moreover, the hinge part 4 can be made into a simple structure, and it becomes a thing with few failures.
[0045]
Further, since the support plate 10 that holds the small battery 20 is provided on the axial center of the case main body 3 on the inner surface of the case main body 3, the small battery 20 can be easily (radially) with respect to the case main body 3. Therefore, the case can be accurately filled in the battery housing portion of the electrical product.
