【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図１は、本発明の第１の実施形態における電池接触接片が電子機器としての外装部材を除くカメラの筐体内に組み付けられ、組立てられた状態を示す後方から観察した斜視図、図２は、図１の電池接触接片をカメラ筐体に組み付ける工程を示す分解斜視図、図３は、図２の電池接触接片をカメラ筐体に組み付けた状態を示す斜視図、図４は、カメラ筐体に組み付けた電池接触接片を切断する工程を示す分解斜視図である。
【０００９】
なお、本発明の組立方法によって電池接触接片を組み付ける電子機器は、本実施形態においては、カメラを例に挙げて説明するが、本発明の組立方法は電池収容室を有する電子機器であれば、どのような電子機器にも適用されることは云うまでもない。
【００１０】
先ず、本発明の組立方法に用いられる電池接触接片の構成を、図２によって説明すると、電池接触接片１は、１本の弾性線材を次のように折り曲げて形成される。即ち、下端部をクランク状に折り曲げ、一端７に係止端部を形成した後、水平に折り曲げられた正極用接片部３を形成し、しかる後、上方に立ち上げて電池の軸方向の長さより、やや長い正極用接片９を形成し、続いてコの字状に折り返した接片連結部４を形成した後、上端部を渦巻螺旋部に形成し、これを負極用接片部２としたものである。なお、リード部６と負極用接片部２とで負極用接片８を形成している。また、上記接片連結部４の両端垂直部は、電気基板に接続されるリード部５、６として用いられる。即ち、正極用接片９と、負極用接片８とは一体的に形成されている。
【００１１】
次に、この電池接触接片１が組み付けられる電子機器としてのカメラについて説明する。
図１は、カメラ本体をなすカメラ筐体１０を後方斜め上方から見た図であって、この筐体１０の前面には、被写体を撮像するための撮影光学系を有するレンズ鏡筒１３が配設されており、上面左側には、被写体にストロボ光を照射するためのストロボ発光部１２が配設されている。また、上面右側には、上面中央に配設されたボス軸１９（図２参照）に位置決め用孔１７を挿通してネジ１８を上記ボス軸１９のネジ穴に螺合することにより固定した例えばＤＣ−ＤＣコンバータ等の電気基板１４が配設されており、この電気基板１４の右側縁部には、上記電池接触接片１の負極用接片８の電気的接合部となる切欠き１５と半田ランド２４ｂ、正極用接片９の電気的接合部となる切欠き１６と半田ランド２４ａが前記カメラ筐体１０の厚味方向に沿って前後に設けられている。さらに、上記カメラ筐体１０の背面左側には、撮影モードや撮像された被写体像等を表示するためのＬＣＤ表示部１１が配設されている。
【００１２】
そして、図１、２に示すように上記カメラ筐体１０の右側端部には、カメラに駆動電力を供給するための電源電池を着脱自在に収納する電池収容室２０が設けられており、この電池収容室２０の開口部の天井壁には、上記電池接触接片１の負極用接片８のリード部６を挿通するための切欠き２１、正極用接片９のリード部５を挿通するための切欠き２２が前記カメラ筐体１０の厚味方向に沿って前後に設けられており、この切欠き２１、２２は、上記電気基板１４がカメラ筐体１０の上面に取り付けられたときには、同基板１４の上記切欠き１５、１６に対向するようになっている。さらに、この電池収容室２０の下面には、電池接触接片の正極用接片９を固定するための位置決め穴２３が穿設されている。
【００１３】
このように構成されたカメラ筐体１０に対して、上記電池接触接片１は、次のようにして組み付けられるようになっている。即ち、前記電池収容室２０の下面の前記位置決め穴２３には、電池接触接片１の正極用接片９の一端７が係止され、正極用接片部３が前記電池収容室２０の下面上に配置されると共に、上方に延び出した正極用接片９は、収容室２０のカメラ前方寄りの内壁に沿って配設され、その上部のリード部５が上記切欠き２２に挿通され、さらに前記電気基板１４の切欠き１６に係合し、これに前記半田ランド２４ａを介して半田付け等によって電気的に接合される。
【００１４】
また、電気基板１４上に延び出した接片連結部４は、図３に示すように、その他方のリード部６が電気基板１４の切欠き１５に係合されたのち、上記切欠き２１に挿通され、その渦巻き状の負極用接片部２が電池収容室２０の天井壁面に配設される。そして、前記電気基板１４の切欠き１５に係合したリード部６が前記半田ランド２４ｂに半田付け等によって電気的に接合される。
【００１５】
次に、このように前記カメラ筐体１０に組み付けられた前記正極用接片９、及び前記負極用接片８における負極用接片部２及び正極用接片部３の組立方法について説明する。
ここで上記正極用接片９、及び前記負極用接片８は、これらの前記リード部５、６が連結部４で互いに連結された電池接触接片１（図２参照）の状態で供給されるものである。
【００１６】
尚、前記電池接触接片１を構成する線材は、例えばＳＷＣ（硬鋼線）や、心材がバネ用高炭素鋼からなり、その表層に銅メッキを施したＣＰ線と称する線材で構成され、これらの線材を前述のように曲げ形成加工することによって上述の各部を構成する。
【００１７】
以下、上記正極用接片９、及び前記負極用接片８における負極用、正極用接片部２、３の組立方法の一例を説明する。
まず、前記カメラ筐体１０に、上記電気基板１４を前記上面中央に配設されたボス軸１９に前記電気基板１４に穿設された位置決め用孔１７を挿通してネジ１８をボス軸１９のネジ孔に螺合することにより組み付け固定する。
【００１８】
次に、上記電池接触接片１を前記電池収容室２０に上述したように一体に組み込み、その後、リード部５，６それぞれを前記電気基板１４の上記半田ランド２４ａ、２４ｂそれぞれに、例えば半田等により電気的に接続する（図３参照）。そして、図４に示すように、上記電池接触接片１の連結部４、即ち、上記正極用接片９と上記負極用接片８との間を例えばペンチ４０またはニッパ等で切断することにより、上記電池接触接片１は、上記正極用接片９と上記負極用接片８とに分離されたことになり、上記電池収容室２０には、電池５０を挿入した際、この電池５０の正極５１に接触する上記正極用接片部３と負極５２に接触する上記負極用接片部２がそれぞれ形成されると共に、この接片部２、３の、電気基板１４の所定の箇所への接続工程も同時に完了する。
【００１９】

【００２１】
以上の組立方法によれば、上記電池接触接片１の上記切断前に上記カメラ筐体１０（電子機器）に組み付けられている、若しくは組み付けられる上記電気基板１４に、上記電池接片１を半田により電気的接続することができる。また、上述までの組立実施形態における上記電池接触接片１の上記切断は、上記電気基板１４に対し半田付けされた後に行われるが、これとは反対に、上記カメラ筐体１０（電子機器）に組み付けられている上記電池接触接片１の上記切断後に上記カメラ筐体１０（電子機器）に組み付けられている、若しくは組み付けられる上記電気基板１４に、上記電池接触接片１を半田により電気的接続することにしても良い。この方法によれば、前者に比べ、半田部分に不必要な応力を与えることもなく電気的接続部分の電気的導通の信頼性を高めることができる。さらに、上記第１実施形態の組立方法の変形例として、
（２） 上記電池接触接片１の連結部４を切断し、それぞれ前記正極用接片９、並びに前記負極用接片８を形成後、これを上記カメラ筐体１０に組み付け、しかる後、前記電気基板１４を上記カメラ筐体１０に組み付け固定して前記正極用接片９、並びに前記負極用接片８と電気的に接続させる。
