【００１３】
ここに掲げる充電装置Ａは、携帯電話器であるコードレス電話器Ｂを充電するのに使用される充電装置であって、コードレス電話器Ｂが装着される凹部１１０Ａを有し、且つこの凹部１１０Ａの底面の当該コードレス電話器Ｂの充電端子１０、１０に対向する位置に開口１１１Ａ、１１１Ａが形成されたケース１００と、ケース１００内に保持されており且つ先端部２１０、２１０が開口１１１Ａ、１１１Ａを通じてコードレス電話器Ｂの充電端子１０、１０に接触可能である一対の給電端子２００、２００と、ケース１００内に保持されており、且つ充電用アダプタ( 図示しない) のプラグＣが装着されるコネクタ３００とを具備している。以下、各部を詳しく説明する。
【００１４】
ケース１００は、図１に示すように、樹脂製の成形品であって、凹部１１０Ａを有する上ケース１００Ａと、この上ケース１００Ａに取り付けられる下ケース１００Ｂとで構成されている。上ケース１００Ａの後端部には、コネクタ３００のプラグ側端子部３１１を露出させるための切欠き部１１２Ａが設けられている。下ケース１００Ｂには、図１及び２に示すように、給電端子２００のコイル部２３０、２３０が嵌合し保持される保持部１１０Ｂ、１１０Ｂと、上ケース１００Ａの開口１１１Ａ、１１１Ａの下側近傍に設けられており且つ給電端子２００の先端部２１０を係止する係止片１２０Ｂ、１２０Ｂと、給電端子２００、２００の後端部２２０、２２０を支持するための溝１３１Ｂが形成された壁部１３０Ｂと、コネクタ３００の他端側が載置される載置台１４０Ｂとが設けられている。
【００１５】
給電端子２００、２００は、図２及び図３に示すように、金属線を折り曲げたばね部材であって、コイル状に巻かれたコイル部２３０、２３０と、このコイル部２３０、２３０の一方の端部から伸び且つ略へ字状に折り曲げられた先端部２１０、２１０と、このコイル部２３０、２３０の他方の端部から伸び且つ先端部２１０、２１０と反対の方向に向けて折り曲げられた後端部２２０、２２０とを有する。コイル部２３０、２３０は先端部２１０、２１０をケース１００の開口１１１Ａ、１１１Ａから突出させる方向に付勢するようになっている。先端部２１０、２１０はコイル部２３０、２３０により開口１１１Ａ、１１１Ａに向けての付勢され、下ケース１００Ｂの係止片１２０Ｂ、１２０Ｂに当接して係止される。後端部２２０、２２０は、壁部１３０Ｂの溝１３１Ｂに支持される。なお、先端部２１０、２１０はメッキ加工が施されている。
【００１６】
コネクタ３００は、図２及び図４に示すように、一端部が下ケース１００Ｂの後端部に、他端部が下ケース１００Ｂの載置台１４０Ｂに載置され、この状態で上ケース１００Ａが取り付けられることによって、ケース１００に収容保持される。
【００１７】
このコネクタ３００は、プラグＣの端子に電気的に接続される端子部３１０が設けられている。この端子部３１０は、充電用アダプタのプラグＣの端子が機械的に接続されるプラグ用端子部３１１と、このプラグ用端子部３１１に設けられた貫通孔である一対の端子孔３１２、３１２と、端子孔３１２、３１２に挿入されるピン部材である一対の接続体３１３、３１３とを有している。
【００１８】
プラグ用端子部３１１は、コネクタ３００の一端部に設けられている。端子孔３１２、３１２はコネクタ３００を貫通する貫通孔である。接続体３１３、３１３は、端子孔３１２、３１２に挿入された状態で一端部が給電端子２００、２００の後端部２２０、２２０を保持し、他端部がプラグ側端子部３１１に充電用アダプタのプラグＣの端子( 図示せず) に接触可能に露出するようになっている。
【００１９】
具体的には、接続体３１３、３１３の一端部には、円筒状の凹部３２１、３２１が設けられており、この凹部３２１、３２１に給電端子２００、２００の後端部２２０、２２０が挿入され保持されるようになっている。この凹部３２１、３２１は、接続体３１３、３１３の中心軸と給電端子２００、２００の後端部２２０、２２０中心軸とが同軸上になるように構成されている。従って、給電端子２００、２００に接続体３１３、３１３を取り付け、この給電端子２００、２００及び接続体３１３、３１３を端子孔３１２、３１２に挿入するだけで、給電端子２００、２００とコネクタ３００とが機械的に且つ電気的に接続される。
【００２０】
一方、接続体３１３、３１３の他端部は挿入された状態で端子孔３１２、３１２の一方から突出するようになっている。すなわち、接続体３１３、３１３の他端部はプラグ用端子部３１１にプラグＣの端子に接触可能に露出している。従って、プラグＣの端子がプラグ用端子部３１１に機械的に接続されると、接続体３１３、３１３がプラグＣの端子に電気的に接続される。このようにして給電端子２００、２００とプラグＣとが接続体３１３、３１３を介して電気的に接続される。
【００２１】
このように構成された充電装置Ａによる場合、給電端子２００、２００の後端部２２０、２２０にコネクタ３００の接続体３１３、３１３を取り付け、この給電端子２００、２００の後端部２２０、２２０及び接続体３１３、３１３をコネクタ３００の端子孔３１２、３１２に挿入するだけで、給電端子２００、２００がコネクタ３００に電気的に接続される。このため、従来例のごとく、給電端子２００、２００とコネクタ３００とを電気的に接続するためのケーブルやプリント基板等が不要になり、その結果、低コスト化を図ることができる。また、半田付けや圧着接続を行う必要がないことから、組立てが非常に容易になる。しかも、半田付けや圧着接続は熟練を要する作業であることから、品質の均一化を図ることもできる。
【００２２】
なお、本発明に係る充電装置Ａは携帯電話であるコードレス電話器Ｂだけの適用に止まらず、ＰＨＳ等の携帯型情報端末装置にも当然に適用可能である。また、中継用プラグコネクタ等に応用することが可能である。
【００２３】
コネクタ３００に関しては、上記実施例に限定されず、充電用アダプタのプラグＣの端子に電気的に接続される端子部３１０が設けられており、この端子部３１０に給電端子２００、２００の後端部２２０、２２０が挿入されるようになっているのもである限り、どのようなものを用いてもかまわない。例えば、接続体３１３、３１３を端子孔３１２、３１２と一体的に設けるようにしてもかまわない。
【００２４】
また、コネクタ３００は、接続体３１３、３１３を設けず、給電端子２００、２００の後端部２２０、２２０を端子孔３１２、３１２に直接挿入するように構成することもできる。この場合、給電端子２００、２００の後端部２２０、２２０がプラグＣの端子に電気的に接続されることから、プラグＣの端子の形状を考慮する必要がある。なお、挿入した状態の給電端子２００、２００後端部２２０、２２０を端子孔３１２、３１２に保持させ、給電端子２００、２００コネクタ３００とを一体的に構成することも可能である。
【００２５】
給電端子２００、２００に関しては、先端部２１０、２１０がコードレス電話器Ｂの充電端子１０、１０に接触可能であり、後端部２２０、２２０がコネクタ３００の端子部３１０に挿入され得るものである限り、どのようなものを用いてもかまわない。例えば、給電端子２００、２００の後端部２２０、２２０を平板状にすることもできる。給電端子２００、２００すべてを平板状とすることも当然可能である。このように給電端子２００、２００を平板状にした場合、給電端子２００、２００の先端部２１０、２１０にメッキ加工を施すことが容易になる。
【００２６】
ケース１００に関しては、コードレス電話器Ｂが装着可能な凹部１１０Ａを有し、この凹部１１０Ａにコードレス電話器Ｂの充電端子１０、１０に対向する位置に開口１１１Ａ、１１１Ａが形成されたものである限り、その形状は問わない。
【００２７】
【発明の効果】
以上、説明とおり、本発明の請求項１の充電装置は、携帯電話器や家庭用電話器の子機等のコードレス電話器が装着され、当該コードレス電話器を充電するのに使用される充電装置であって、一端側に上方からコードレス電話器が装着可能な凹部を有し且つこの凹部のコードレス電話器の充電端子と対向する位置に開口が設けられたケースと、このケースに収容され、当該ケースの他端側から充電用アダプタのプラグが装着可能に露出するコネクタと、前記ケースに収容される給電端子と、を備えており、この給電端子は、金属線を折り曲げたバネ部材であって、コイル部と、このコイル部の一方の端部から伸びており且つ前記ケースの開口からコードレス電話器の充電端子に接触可能に突出する略へ字状の先端部と、このコイル部の他方の端部から前記先端部と反対側に向けて伸びており且つ前記端子部に挿入され、前記コネクタと電気的に接続される後端部とを有している。
【００２８】
このような請求項１の充電装置による場合、給電端子の後端部をコネクタの端子部に挿入するだけで、給電端子とコネクタとを電気的に接続することができる。このため、従来例のごとく、給電端子とコネクタとを電気的に接続するためのケーブルやプリント基板等が不要になり、その結果、低コスト化を図ることができる。また、半田付けや圧着接続を行う必要がないことから、組立てが非常に容易になる。しかも、半田付けや圧着接続は熟練を要する作業であることから、品質の均一化を図ることもできる。また、給電端子の先端部が前記開口から突出する方向に付勢されるように構成することによって、給電端子の先端部とコードレス電話器の充電端子との間に所定の接触圧を確保することができる。
【００２９】
本発明の請求項２の充電装置は、前記コネクタの端子部は、充電用アダプタのプラグの端子が機械的に接続されるプラグ側端子部と、このプラグ用端子部に設けられた貫通孔である端子孔と、この端子孔に挿入されるピン部材であり、且つ挿入された状態でカップ状の一端部が前記給電端子の後端部を保持し、他端部が前記プラグ側端子部にプラグの端子に接触可能に露出する接続体とを有している。このような請求項２の充電装置による場合、前記プラグ側端子部にプラグの端子が機械的に接続されると、前記接続体がプラグの端子に電気的に接続される。このため、プラグの端子の形状を考慮する必要がない。
【００３１】
本発明の請求項３の充電装置は、携帯電話器や家庭用電話器の子機等のコードレス電話器が装着され、当該コードレス電話器を充電するのに使用される充電装置であって、一端側に上方からコードレス電話器が装着可能な凹部を有し且つこの凹部のコードレス電話器の充電端子と対向する位置に開口が設けられたケースと、このケースに収容され、当該ケースの他端側から充電用アダプタのプラグが装着可能に露出するコネクタと、前記ケースに収容される給電端子と、を備えており、このコネクタは、充電用アダプタのプラグが機械的に接続されるプラグ側端子部と、このプラグ側端子部に設けられた貫通孔である端子孔とを有しており、前記給電端子は、金属線を折り曲げたバネ部材であって、コイル部と、このコイル部の一方の端部から伸びており且つ前記ケースの開口からコードレス電話器の充電端子に接触可能に突出する略へ字状の先端部と、このコイル部の他方の端部から前記先端部と反対側に向けて伸びており且つ前記端子孔に挿入され、充電用アダプタのプラグに電気的に接続可能に露出する後端部とを有している。
【００３２】
このような請求項３の充電装置による場合、前記コネクタの端子孔に前記給電端子の後端部を挿入するだけで、当該給電端子と前記コネクタとが電気的に接続されるので、請求項１と同様の効果を奏する。
