Abstract

<P>PROBLEM TO BE SOLVED: To provide a battery contact member and a battery housing structure enabling a battery power supply to be stably taken out because of low contact resistance. <P>SOLUTION: The battery housing structure 1 has a conductive spring 4 secured to one end of a battery 3 inside a battery storage case 2 for biasing the battery 3 toward the other end. A bent end portion 4a which is bent in the opposite direction from the battery 3 is formed at the end of the spring 4 making contact with the battery 3. A lead wire 5 is connected to the bent end portion 4a and drawn out of the battery storage case 2 through an exit port 7 for the lead wire 5. The exit port 7 is shaped to permit movement of the lead wire 5 upon deformation of the spring 4. This prevents imperfect contact from occurring as the result of load application to the lead wire 5 or the like when the battery 3 is moved into or out of the battery storage case 2, while also reducing resistance values and stably supplying a voltage close to the proper battery voltage at reduced cost. <P>COPYRIGHT: (C)2004,JPO&NCIPI

近時、デジタルカメラに代表されるように、カメラ等の機器においても電池でその動作が駆動されるようになってきている。このような機器においては、一般的に、機器本体に設けた電池収納室内に電池を着脱可能に収納している。この電池収納室内には、収納する電池を安定して保持するとともに、電池の電極方向に配設された接点端子と、当該接点端子方向に電池を付勢する弾性接点部材と、が配設されており、収納電池を弾性接点部材で接点端子方向に付勢している。そして、このような機器に設けられた電池収納構造においては、電池の電圧を正確にかつ安定して機器に供給する電池収納構造が要望されている。
【０００３】
そして、従来、カメラ本体に設けられた電池収納室と、この電池収納室に収納可能に設けられた電池マガジンと、この電池マガジンの内部に並列的に形成された複数の電池装填部と、これらの電池装填部に対し極性を逆にして交互に装填される電池のうち、隣接する一組の電池の相互接続されるべきプラス側電極とマイナス側電極との間を短絡するための電池間短絡片と、この電池間短絡片を前記一組の電池のプラス側電極およびマイナス側電極から遠ざかる方向へ偏倚させる偏倚スプリングと、前記電池マガジンが前記電池収納室内に収納されたとき、前記電池間短絡片を前記偏倚スプリングの偏倚力に抗して前記一組の電池のプラス側電極およびマイナス側電極に対して圧接させる圧接スプリングと、を備えたカメラ電池収納装置が提案されている（特許文献１参照）。
【０００４】
また、従来、第１の乾電池の正極と接触する正極接点部と、第２の電池の負極と接触する負極接点部とを有し、第１の乾電池の負極と第２の電池の正極とを直接接触させて、これら２個の乾電池を直列接続で直線状に保持する乾電池ホルダにおいて、前記正極接点部を、前記乾電池の正極の凸状部が入り込む穴を有する絶縁体とこの穴の底部に設けられた、前記正極と接触する正極接片とから構成し、また、前記負極接点部を、中心部に設けた少なくとも前記乾電池の正極の凸状部の径よりも大きい径の絶縁体と、この絶縁体の外側に設けられた、前記負極の外縁部近傍に接触する負極接片から構成し、これら正極接点部と負極接点部の内の少なくともいずれか一方を、前記正極か前記負極に押しつける方向に移動可能に付勢した乾電池ホルダが提案されている（特許文献２参照）。
【０００５】
すなわち、これらの従来技術は、バネ圧力を生成するコイルスプリングと、内部抵抗を軽減する接点部材を備えている。
【０００６】
コイルスプリングを用いる場合、一般的に、図５に示すように、電池収納室１００の一端側の壁面にコイルスプリング１０１の一端部を固定し、コイルスプリング１０１の他端部で電池１０２を他方側に付勢する。そして、コイルスプリング１０１の電池収納室１００側の端部を半田１０３でリード線１０４に接続している。
【０００７】
また、従来、図６に示すように、付勢手段として、板バネ１１０を使用したものがあるが、板バネ１１０を使用した場合、板バネ１１０の一端側で電池１１１を付勢し、板バネ１１０の他端側に半田１１２でリード線１１３を接続している。
【０００８】
【発明が解決しようとする課題】
しかしながら、このような従来技術にあっては、安定した接触圧力を確保して接触抵抗を低減し、安定して電池本来の電圧を供給する上で、改良の必要があった。
【０００９】
すなわち、上記従来技術は、バネ圧力を生成するコイルスプリングだけでは、電池と電池接点部材の接触個所から電池接点部材のリード線引き出し個所またはプリント基板との半田付け個所までの距離が長くなって、抵抗値が大きくなり、電池本来の電圧よりも極端に低い電圧しか供給されないという問題があった。また、板バネを使用した場合には、電気抵抗は小さいが、ストロークが短いため、安定した接触圧力を確保するのが困難であるという問題がある。
【００１０】
また、スプリングと内部抵抗を軽減する接点部材組み合わせものを備えたものはコストが高くなるという欠点がある。

【００１５】

【００２６】
【発明の実施の形態】
以下、本発明の好適な実施の形態を添付図面に基づいて詳細に説明する。なお、以下に述べる実施の形態は、本発明の好適な実施の形態であるから、技術的に好ましい種々の限定が付されているが、本発明の範囲は、以下の説明において特に本発明を限定する旨の記載がない限り、これらの態様に限られるものではない。
【００２７】
図１は、本発明の電池接点部材及び電池収納構造の第１の実施の形態を適用した電池収納構造１の要部正面図である。
【００２８】
図１において、電池収納構造１は、電池収納ケース（電池収納部材）２内に電池３が着脱可能に収納され、電池収納ケース２内の一端側には、電池３を電池収納ケース２内の他端側に付勢するスプリング４が配設されている。
【００２９】
スプリング（電池接点部材）４は、その基端側端部が電池収納ケース２の一端側に固定されており、その先端側端部は、電池３とは反対側に曲げられていて、当該曲げられた先端部（屈曲端部）４ａに、導電部材であるリード線５が半田６により接続されている。
【００３０】
スプリング４の基端側には、複数の屈曲部４ｂが設けられており、スプリング４は、当該複数の屈曲部４ｂが電池収納ケース２に係合されることで、その基端部が電池収納ケース２の一端側に固定されている。
【００３１】
スプリング４は、所定の導電性を有するとともに、その変形量に応じて力量の変化する弾性を有する部材で形成されており、電池３の一端側の端子３ａに接触しつつ、電池３を電池収納ケース２内の他端側に付勢する。この電池収納ケース２内の他端側には、図示しないが、接点部材が配設されており、電池３は、スプリング４により他端側に付勢されることで、他端側の接点部材と電池３の他端側端子が接触する。
【００３２】
電池収納ケース２のスプリング４の配設されている側の側面には、スプリング４に接続されているリード線５を電池収納ケース２の外部に引き出すための引き出し口（取り出し口）７が形成されており、引き出し口７は、スプリング４の屈伸に伴って移動する方向に所定長さにわたって形成されていて、当該引き出し口７の長さが、少なくともスプリング４が最も屈曲した状態から最大に伸張した状態においてもリード線５が引き出し口７内を移動可能な長さに形成されている。
【００３３】
次に、本実施の形態の作用を説明する。本実施の形態の電池収納構造１は、電池収納ケース２内に電池収納ケース２に固定されているスプリング４の先端部で、当該電池収納ケース２内に着脱可能に収納された電池３を、当該電池３の一端側の端子３ａに接触しつつ他端側に付勢し、スプリング４は、その先端部が電池３と反対側に屈曲された屈曲端部４ａが形成されているとともに、当該スプリング４の屈曲端部４ａに、リード線５が接続されている。スプリング４は、その基端側の複数の屈曲部４ｂが電池収納ケース２の一端側に係合されることで、その基端部が電池収納ケース２の一端側に固定されている。
【００３４】
したがって、電池３の端子３ａとリード線５との距離が短く、抵抗値を小さくして、電池３本来の電圧に近い電圧をリード線５を介して安定して供給することができるとともに、簡単な構造で安価なものとすることができる。
【００３５】
また、電池収納構造１は、リード線５を引き出し口７を通して電池収納ケース２の外部に引き出しているが、この引き出し口７が、少なくともスプリング４が最も屈曲した状態から最大に伸張した状態においてもリード線５が引き出し口７内を移動可能な長さに形成されている。
【００３６】
したがって、スプリング４の伸縮に伴ってリード線５が引き出し口７内をスムースに移動し、リード線５やリード線５とスプリング４との接続部である半田６部分に負荷がかかることを防止し、電池３の出し入れ時に接触不良が発生することを防止することができる。
【００３７】
なお、上記スプリング４は、その電池３側である先端側端部が、電池３と反対側に屈曲された屈曲端部４ａとなっているものに限るものではなく、例えば、図２に示すように、少なくとも電池３の外径を越えるまでは水平に延長された延長端部４ｃとして形成されているものであってもよい。なお、図２では、上記図１の構成と同様の構成部分には、同一の符号を付している。
【００３８】
この場合、引き出し口７は、延長端部４ｃの少なくとも電池３の外形を超えた部分が水平状態で引き出し口７が通過する大きさに形成されており、この引き出し口７を通過した延長端部４ｃの先端部に、導電部材であるリード線５が半田６により接続される。
【００３９】
この場合においても、電池３の端子３ａとリード線５との距離が短く、抵抗値を小さくして、電池３本来の電圧に近い電圧をリード線５を介して安定して供給することができるとともに、簡単な構造で安価なものとすることができる。
【００４０】
このように、本実施の形態の電池収納構造１の電池接点部材であるスプリング４は、電池３の一端側端子３ａ部分に接触して当該電池３を電池３の他端側端子方向に付勢するとともに、その変形量に応じて力量の変化する弾性と導電性を有するスプリング４の電池３と接触する側の端部に、当該電池３とは反対方向に屈曲された屈曲端部４ａあるいは少なくとも当該電池３の外径を越えるまでは水平に延長されている延長端部４ｃを形成している。
【００４１】
したがって、特別な部材等を新たに設けることなく、屈曲端部４ａまたは延長端部４ｃの電池３の外径を越えた部分に電池３の電源を取り出すリード線５を接続することで、電池３の端子の近くから電源を取り出して、抵抗値を低減させることができ、電池本来の電圧に近い電圧を安価に供給することができる。
【００４２】
また、本実施の形態の電池収納構造１のスプリング４は、その屈曲端部４ａあるいは延長端部４ｃの電池３の外径を越えた部分に、スプリング４を通して電池３の電源を取り出すリード線５を接続している。
【００４３】
したがって、特別な部材等を新たに設けることなく、電池３の端子の近くから電源を取り出して、抵抗値を低減させることができ、電池本来の電圧に近い電圧を安価に供給することができる。
【００４４】
さらに、本実施の形態の電池収納構造１のスプリング４は、その電池３と接触する側と反対側の端部部分に、スプリング４を電池３を収納する電池収納ケース２に係合させて固定する複数の屈曲部４ｂを形成している。
【００４５】
したがって、特別な部材等を新たに設けることなく、スプリング４を電池収納ケース２に固定することができ、電池本来の電圧に近い電圧をより一層安価に供給することができる。
【００４６】
また、本実施の形態の電池収納構造１は、電池３を着脱可能に収納する電池収納ケース２内の電池３の一端側に、電池３の一端側端子３ａ部分に接触して電池３を電池３の他端側端子方向に付勢するとともにその変形量に応じて力量の変化する弾性と導電性を有するスプリング４を固定し、スプリング４の電池３と接触する側の端部に、電池３とは反対方向に屈曲された屈曲端部４ａあるいは少なくとも電池３の外径を越えるまでは水平に延長されている延長端部４ｃを形成し、当該屈曲端部４あるいは当該延長端部４ｃの電池３の外径を越えた部分に、スプリング４を通して電池３の電源を取り出すリード線５を接続し、リード線５を、電池収納ケース２に形成された引き出し口７を通して電池収納ケース２の外部に取り出し、引き出し口７を、スプリング４の変形によるリード線５の移動を許容する形状に形成している。
【００４７】
したがって、電池収納ケース２への電池３の出し入れ時にリード線５やスプリング４及びスプリング４とリード線５との接続部等に負荷がかかることによる接触不良の発生を防止することができるとともに、電池３の端子の近くから電源を取り出して、抵抗値を低減させることができ、電池本来の電圧に近い電圧を安定してかつ安価に供給することができる。
【００４８】
図３は、本発明の電池接点部材及び電池収納構造の第２の実施の形態を適用した電池収納構造１０の要部正面図である。
【００４９】
図３において、電池収納構造１０は、電池収納ケース（電池収納部材）１１内に電池１２が着脱可能に収納され、電池収納ケース１１内の一端側には、電池１２を電池収納ケース１１内の他端側に付勢するスプリング１３が配設されている。
【００５０】
スプリング（電池接点部材）１３は、その基端側端部が電池収納ケース１１の一端側に固定されており、その先端側端部は、当該スプリング１３の軸中心部において、電池１２とは反対側に曲げられていて、当該曲げられた屈曲端部１３ａに、導電部材であるリード線１４が半田１５により接続されている。
【００５１】
スプリング１３の基端側には、複数の屈曲部１３ｂが設けられており、スプリング１３は、当該複数の屈曲部１３ｂが電池収納ケース１１に係合されることで、その基端部が電池収納ケース１１の一端側に固定されている。
【００５２】
スプリング１３は、所定の導電性を有するとともに、その変形量に応じて力量の変化する弾性を有する部材で形成されており、電池１２の一端側の端子１２ａに接触しつつ、電池１２を電池収納ケース１１内の他端側に付勢する。この電池収納ケース１１内の他端側には、図示しないが、接点部材が配設されており、電池１２は、スプリング１３により他端側に付勢されることで、他端側の接点部材と電池１２の他端側端子が接触する。
【００５３】
電池収納ケース１１のスプリング４の配設されている側の端面には、スプリング１３に接続されているリード線１４を電池収納ケース１１の外部に引き出すための引き出し口（取り出し口）１６が形成されており、引き出し口１６は、スプリング１３の中心軸部分の当該スプリング１３の基端部を支持する電池収納ケース１１に形成されている。
【００５４】
スプリング１３の屈曲端部１３ａに接続されたリード線１４は、スプリング１３の中心軸を通過して引き出し口１６から電池収納ケース１１外に引き出され、当該引き出し口１６から電池収納ケース１１外に引き出されたリード線１４は、必要に応じて折り曲げられるが、スプリング１３が最大に伸張した状態で電池収納ケース１１に当接しない長さを有した位置で折り曲げられる。
【００５５】
次に、本実施の形態の作用を説明する。本実施の形態の電池収納構造１０は、電池収納ケース１１内に電池収納ケース１１の一端側に固定されているスプリング１３の先端部で、当該電池収納ケース１１内に着脱可能に収納された電池１２を、当該電池１２の一端側の端子１２ａに接触しつつ他端側に付勢し、スプリング１３は、当該スプリング１３の軸中心部で、その先端部が電池１２と反対側に屈曲された屈曲端部１３ａが形成されていて、当該スプリング１３の屈曲端部１３ａに、リード線１４が接続されている。スプリング１３は、その基端側の複数の屈曲部１３ｂが電池収納ケース１１の一端側に係合されることで、その基端部が電池収納ケース１１の一端側に固定されている。
【００５６】
したがって、電池１２の端子１２ａとリード線１４との距離が短く、抵抗値を小さくして、電池１２本来の電圧に近い電圧をリード線１４を介して安定して供給することができるとともに、簡単な構造で安価なものとすることができる。
【００５７】
また、電池収納構造１０は、リード線１４をスプリング１３の中心軸を通過させて、スプリング１３の中心軸上に位置する電池収納ケース１１に形成された引き出し口１６を通させて電池収納ケース１１の外部に引き出している。また、このスプリング１３の屈曲端部１３ａに接続され、スプリング１３の中心軸を通過して引き出し口１６から電池収納ケース１１外に引き出されたリード線１４は、必要に応じて折り曲げられるが、スプリング１３が最大に伸張した状態で電池収納ケース１１に当接しない長さを有した位置で折り曲げられる。
【００５８】
したがって、スプリング１３の伸縮に伴ってリード線１４が引き出し口１６内をスムースに移動し、リード線１４やリード線１４とスプリング１３との接続部である半田１５部分に負荷がかかることを防止することができる。

【００６１】
図４において、電池収納構造２０は、上記第２の実施の形態と同様に、電池収納ケース１１内に電池１２が着脱可能に収納され、電池収納ケース１１内の一端側には、電池１２を電池収納ケース１１内の他端側に付勢するスプリング１３が配設されている。
【００６２】
スプリング１３は、その基端側端部が電池収納ケース１１の一端側に固定されており、その先端側端部は、当該スプリング１３の軸中心部で、電池１２とは反対側に曲げられていて、当該曲げられた屈曲端部１３ａに、導電部材であるリード線１４が半田１５により接続されている。
【００６３】
スプリング１３の基端側には、複数の屈曲部１３ｂが設けられており、スプリング１３は、当該複数の屈曲部１３ｂが電池収納ケース１１に係合されることで、その基端部が電池収納ケース１１の一端側に固定されている。
【００６４】
スプリング１３は、所定の導電性を有するとともに、その変形量に応じて力量の変化する弾性を有する部材で形成されており、電池１２の一端側の端子１２ａに接触しつつ、電池１２を電池収納ケース１１内の他端側に付勢する。この電池収納ケース１１内の他端側には、図示しないが、接点部材が配設されており、電池１２は、スプリング１３により他端側に付勢されることで、他端側の接点部材と電池１２の他端側端子が接触する。
【００６５】
電池収納ケース１１のスプリング４の配設されている側の端面には、スプリング１３に接続されているリード線１４を電池収納ケース１１の外部に引き出すための引き出し口１６が形成されており、引き出し口１６は、スプリング１３の中心軸部分の当該スプリング１３の基端部を支持する電池収納ケース１１に形成されている。
【００６６】
そして、電池収納ケース１１の引き出し口１６の設けられている部分には、円筒軸（中空部材）２１が固定されており、円筒軸２１は、スプリング１３内をスプリング１３の中心軸に沿って、スプリング１３の先端方向、すなわち、電池１２方向に所定量突出する状態で配設されている。円筒軸２１は、スプリング１３が最も屈曲した状態のときに、スプリング１３の先端部、すなわち、電池１２が円筒軸２１の先端に当接しない長さに形成されている。
【００６７】
スプリング１３の屈曲端部１３ａに接続されたリード線１４は、スプリング１３の中心軸を通過するとともに、途中から円筒軸２１内を通過して引き出し口１６から電池収納ケース１１外に引き出され、当該引き出し口１６から電池収納ケース１１外に引き出されたリード線１４は、必要に応じて折り曲げられるが、スプリング１３が最大に伸張した状態で電池収納ケース１１に当接しない長さを有した位置で折り曲げられる。
【００６８】
次に、本実施の形態の作用を説明する。本実施の形態の電池収納構造２０は、電池収納ケース１１内に電池収納ケース１１の一端側に固定されているスプリング１３の先端部で、当該電池収納ケース１１内に着脱可能に収納された電池１２を、当該電池１２の一端側の端子１２ａに接触しつつ他端側に付勢し、スプリング１３は、当該スプリング１３の軸中心部で、その先端部が電池１２と反対側に屈曲された屈曲端部１３ａが形成されていて、当該スプリング１３の屈曲端部１３ａに、リード線１４が接続されている。スプリング１３は、その基端側の複数の屈曲部１３ｂが電池収納ケース１１の一端側に係合されることで、その基端部が電池収納ケース１１の一端側に固定されている。
【００６９】
したがって、電池１２の端子１２ａとリード線１４との距離が短く、抵抗値を小さくして、電池１２本来の電圧に近い電圧をリード線１４を介して安定して供給することができるとともに、簡単な構造で安価なものとすることができる。
【００７０】
また、電池収納構造１０は、リード線１４をスプリング１３の中心軸を通過させて、スプリング１３の中心軸上に位置する電池収納ケース１１に形成された引き出し口１６を通させて電池収納ケース１１の外部に引き出している。また、電池収納ケース１１の引き出し口１６の設けられている部分には、スプリング１３内をスプリング１３の中心軸に沿って、スプリング１３の先端方向に所定量突出する状態で円筒軸２１が固定されており、円筒軸２１は、スプリング１３が最も屈曲した状態のときに、スプリング１３の先端部、すなわち、電池１２が円筒軸２１の先端に当接しない長さに形成されている。さらに、スプリング１３の屈曲端部１３ａに接続されたリード線１４は、スプリング１３の中心軸を通過するとともに、途中から円筒軸２１内を通過して引き出し口１６から電池収納ケース１１外に引き出され、当該引き出し口１６から電池収納ケース１１外に引き出されたリード線１４は、必要に応じて折り曲げられるが、スプリング１３が最大に伸張した状態で電池収納ケース１１に当接しない長さを有した位置で折り曲げられる。
【００７１】
したがって、スプリング１３は、屈曲した際に、当該スプリング１３の中心部に円筒軸２１が位置するため、スプリング１３が座屈することが防止され、スプリング１３により電池１２を適切に付勢することができ、より一層安定して電源を供給することができる。また、スプリング１３の伸縮に伴ってリード線１４が引き出し口１６内をスムースに移動し、リード線１４やリード線１４とスプリング１３との接続部である半田１５部分に負荷がかかることを防止することができる。
【００７２】
このように、本実施の形態の電池収納構造２０は、スプリング１３を、少なくとも電池１２の一端側と他端側とを結ぶ延長線上部分で電池収納ケース１１に固定して、当該延長線上で変形して弾性を電池１２に付与するとともに、屈曲端部１３ａを、当該延長線上で電池１２とは反対方向に屈曲させ、引き出し口１６を、スプリング１３の固定されている延長線上の電池収納ケース１１に形成し、引き出し口１６部分の電池収納ケース１１に、引き出し口１６部分からスプリング１３の最大変形量の変形を許容する長さにわたって延長線上に沿って延在する円筒軸２１を固定し、スプリング１３の屈曲端部１３ａにリード線１４を接続して、リード線１４を、スプリング１３及び円筒軸２１の延長線上を通過させて引き出し口１６から取り出している。
【００７３】
したがって、電池収納ケース１１への電池１２の出し入れ時にリード線１４やスプリング１３及びリード線１４とスプリング１３との接続部等に負荷がかかることによる接触不良の発生を防止することができるとともに、スプリング１３が変形時に座屈することを円筒軸２１で防止することができ、また、電池１２の端子の近くから電源を取り出して、抵抗値を低減させることができ、電池本来の電圧に近い電圧をより一層安定してかつ安価に供給することができる。
【００７４】
なお、上記第３の実施の形態では、上記第１及び第２の実施の形態と電池の±の方向が逆の場合について示しているが、本発明は、電池の±の方向に関係なく適用することができる。
【００７５】
以上、本発明者によってなされた発明を好適な実施の形態に基づき具体的に説明したが、本発明は上記のものに限定されるものではなく、その要旨を逸脱しない範囲で種々変更可能であることはいうまでもない。
