Description

【０００１】
【発明の属する技術分野】
本発明は、同軸コネクタ用レセプタクルに関するものである。
【０００２】
【従来の技術】
携帯電話機を自動車に持ち込んで使用する際、携帯電話機と嵌合して運転中においても携帯電話機を持たずに通話できるようにしたハンズフリーキットや携帯電話機を固定する装置が提供されている。図１０はハンズフリーキットのような装置Ａと携帯電話機Ｂとを示しており、装置Ａは筐体１の上面に携帯電話機Ｂを載置する載置部１Ａを設け、この載置部１Ａに携帯電話機Ｂの裏部を載置することで装着固定できるようなっている。また携帯電話機Ｂを載置部１Ａに載置固定すると載置部１Ａに設けた同軸コネクタ２と携帯電話機Ｂの裏部に設けたレセプタクル３とが嵌合接続され、同軸コネクタ２の嵌合接続によりレセプタクル３内では携帯電話機Ｂ側の無線通信部のアンテナ接続部と携帯電話機Ｂ側のアンテナとの間を切り離すと同時にアンテナ接続部を同軸コネクタ２側に接続する回路を構成し、自動車側に設けたアンテナに同軸コネクタ２に接続された同軸ケーブルＣを介して無線通信部のアンテナ接続部を接続することができるようになっている。
【０００３】
図１１は従来使用されている同軸コネクタ２とレセプタクル３との嵌合接続前の状態を示しており、この従来例の同軸コネクタ２はレセプタクル３に嵌合される同軸プラグ部４と、同軸ケーブルＣを同軸プラグ部４の同軸ポスト５に接続するためのケーブル接続部６と、同軸コネクタ２を筐体１に取り付けるための取付部７とを備えている。
【０００４】
取付部７は一端で同軸プラグ部４の外部導体９に固定され、他端で筐体１に固定された支持部材８に固定された外形が円錐台形状のコイルばね１０を備えるとともに、筐体１の外側に突出する同軸プラグ部４の先部の軸方向変位を制限するために、同軸プラグ部４の取付部７に対する接合端付近に取り付けた環状の部材１１を備えてなり、コイルばね１０を筐体１に形成した取付孔部１２内に収納するとともに、部材１１を取付孔部１２の開口の周辺の筐体１内側面に当接することで、同軸プラグ部４を軸方向及び径方向に変位可能に保持している。尚２８は埃などが取付孔部１２に入るのを防ぐためのフィルム体である。
【０００５】
同軸プラグ部４は中心に上記の同軸ポスト５を内装した誘電体１３とこの誘電体１３を内装した上記外部導体９とからなる。
【０００６】
ケーブル接続部６は同軸ケーブルＣの誘電体１９の中心に内装された導体２０を収納するための貫通孔２１を有する筒体２２を備え、この筒体２２の外面に同軸ケーブルＣの外被導体２３を収納するようになっている。この外被導体２３は金属環体２４の可塑変形により筒体２２に絞り付けられている。またケーブル接続部６は筒体２２と一体となって筒体２２と直交し同軸プラグ部４の軸方向に延びた通路２５を有するとともに上記貫通孔２１に連結されている導電性ケース部２６を備え、この導電性ケース部２６に上記同軸プラグ部４の端部を嵌合固定し、導電性ケース部２６内に導入された同軸ケーブルＣの導体２０の先端と同軸ポスト５の端部とを半田付けなどにより電気的に接続している。
【０００７】
このように構成された同軸コネクタ２を装着した装置Ａの筐体１の載置台１Ａに携帯電話機Ｂを定位置に載置しようとした場合、携帯電話機Ｂの裏部に設けたレセプタクル３の外部電極体の表面に底部から表面開口に向けて徐々に内径が拡径するように形成した穴部１４に同軸コネクタ２の同軸プラグ部４の先部が嵌まり、このとき携帯電話機Ｂを載置台１Ａ側に押し付けようとする力により同軸プラグ部４の先部が穴部１４のテーパ面に接触するが、コイルばね１０により軸方向及び径方向に同軸プラグ部４が揺動するため、同軸コネクタ２の衝撃を吸収して損傷の危険を低減することができるのである。
【０００８】
そして同軸プラグ部４の先部が穴部１４の中心底部に設けた嵌合凹部１５に嵌合すると、その底面に露出した可動接点体１６の先端を同軸ポスト５の先端が押して可動接点体１６を軸方向に動かしてその可動接点体１６の後端で更に可動ばね板１７を動かし、可動ばね板１７の可動接点１７ａを固定端子１８の接点面から開離させる。可動ばね板１７は携帯電話機Ｂの無線通信部のアンテナ接続部に、固定端子１８は携帯電話機Ｂのアンテナに接続されているため、上記開離によりアンテナが切り離されるとともに無線通信部のアンテナ接続部が可動ばね板１７，可動接点体１６を介して同軸プラグ部４の同軸ポスト５に接続されることで、同軸ケーブルＣを介して自動車側のアンテナに接続されることになる。
【０００９】
【発明が解決しようとする課題】
ところで同軸コネクタ２の同軸プラグ部４の同軸ポスト５は、指等が接触した場合危険なため、外部導体９の先端面より飛び出さないように形成され、これに対応して同軸ポスト５の先端に接触するレセプタクル３側の接触部位を、嵌合凹部１５の底面より露出させている。
【００１０】
上記の従来例では、外部電極体の穴部１４の中心底部に設けた嵌合凹部１５の底面に可動接点体１６の先端を露出させ、同軸ポスト５の先端がこの可動接点体１６の先端に接触させる構造とし、さらにこの接触時に可動接点体１６を押し動かしてその可動接点体１６の後端で更に可動ばね板１７を動かし、可動ばね板１７の可動接点１７ａを固定端子１８の接点面から開離させる構造としている。
【００１１】
このため可動接点体１６、可動接点ばね１７、固定端子１８の３つの部材で同軸ポスト５に対する接触構造と、切り換えスイッチ部とを構成することとなり、部品点数が多く、コスト高となっていた。
【００１２】
本発明は上記の点に鑑みて為されたもので、その目的とするところは同軸ポストとの接触構造とスイッチ接点部とを構成する部品点数を削減でき、製作コストが安価な同軸コネクタ用レセプタクルを提供することにある。
【００１３】
【課題を解決するための手段】
上記目的を達成するために、請求項１の発明では、中心に同軸ポストを貫挿させた誘電体を筒状外部導体内に同心状に設け、上記誘電体の先端より突出する同軸ポストの先端を上記外部導体の先端面より奥側に位置させた同軸プラグ部の先端部が嵌合して上記外部導体が接触する嵌合凹部を表面側に設けた外部電極体と、該外部電極体の裏方に配設され、一端部側が固定されて他端部側を上記外部電極体方向に弾発させた可動ばね板と、上記外部電極体の裏方に配設され、上記可動ばね板の他端部側のばね付勢方向の面に設けられた可動接点が弾接する接点面を備えた固定端子と、上記可動ばね板に一体立設され、先部を上記外部電極体の嵌合凹部の底面に開口した孔より上記外部電極体の嵌合凹部内に臨ませ、該嵌合凹部に上記同軸プラグ部の先端部が嵌合されたときに同軸ポストの先端が上記先部に弾接する接触突片とを備え、上記接触突片の先部に上記同軸ポストの先端が弾接したときに上記可動ばね板が撓んで上記可動接点を上記固定端子の接点面から開離させる同軸コネクタ用レセプタクルであって、上記可動ばね板は、一枚の金属板の打ち抜き加工により形成されたものであって、上記可動接点を可動ばね板の板面に膨出形成するとともに、上記接触突片を切り起こしにより一体立設して成り、上記同軸ポストの先端と接触する接触突片の先部の接触面を打ち抜き加工時のロール面で形成したことを特徴とする。

【００２３】
【発明の実施の形態】
以下本発明を基本形態および実施形態により説明する。
（基本形態１）
本基本形態のレセプタクル３は図１（ａ）に示すように外部電極体６０と、外部電極体６０が上部に被着される合成樹脂成形品のベース６１と、可動ばね板５６と、固定端子５９等から構成される。
【００２４】
ベース６１は有底筒状に合成樹脂により成形されたもので、開口端側の周壁の外側に形成した段部に外部電極体６０の周壁下端が載置されて外部電極体６０が開口部に被着される。
【００２５】
外部電極体６０は携帯電話機等のケースに設けられた取付孔部内に配設される際に、取付孔部の外側開口に臨む表面には底部から表面開口に向けて徐々に内径が拡径した穴部５４が設けられ、この穴部５４の中心底部に図１（ｂ）に示す同軸コネクタ２の同軸プラグ部４の先部を嵌合させるための嵌合凹部５５を設け、嵌合凹部５５の底部の孔５５ａよりベース６１内に設けられた可動ばね板５６に一体立設された接触突片５７の先部を嵌合凹部５５内に挿入している。この接触突片５７の先部の先端は嵌合凹部５５に嵌合される同軸プラグ部４の同軸ポスト５の先端が弾接する接触面を構成する。
【００２６】
ここで可動ばね板５６は一枚のフープ状の金属板を打ち抜いて形成されたもので、図２に示すように中間部に接触突片５７を切り起こしにより一体立設し、一端部からは端子片５６ａを折り曲げ延長形成し、他端部の上面（図１において）には可動接点５８をプレス加工等により膨出形成したもので、一端部に設けた圧入部５６ｂをベース６１の周壁に設けた溝６１ａに圧入することにより一端部がベース６１に固持され、自由端である他端部側を図において上向きに弾発している。端子片５６ａの先部はベース６１外に導出されて例えば携帯電話機の無線回路部（図示せず）に接続される。
【００２７】
固定端子５９はベース６１の周壁に設けた溝６１ｂに中間部に形成した圧入部５９ａを圧入することで周壁に固定されており、一端部をベース６１内に、他端部をベース６１の外側に導出し、一端部の下面を可動ばね板５６の自由端の上面に設けた可動接点５８に対向配置し、可動ばね板５６の弾発により可動接点５８が弾接する接点面を上記下面により構成している。
【００２８】
固定端子５９の他端部は例えば携帯電話機のアンテナと接続される端子部を構成し、同軸コネクタ部４が外部電極体６０の嵌合凹部５５に嵌合されない状態（図１（ａ））で、可動ばね板５６の可動接点５８が固定端子５９の接点面に弾接し、可動ばね板５６に接続される無線通信部（図示せず）と、固定端子５９に接続されたアンテナとが電気的に接続されるようになっている。
【００２９】
而して図１（ｂ）に示すように本基本形態のレセプタクル３の外部電極体６０の穴部５４に設けた嵌合凹部５５に同軸コネクタ２の同軸プラグ部４の先部を嵌合接続すると、同軸コネクタ２の外部導体９が外部電極体６０に接触するとともに、同軸プラブ部４の同軸ポスト５の先端が嵌合凹部５５内に突出している可動ばね板５６の接触突片５７の上端に弾接して、接触突片５７を下方へ押下げる。
【００３０】
これにより可動ばね板５６は一端部を中心として撓み、自由端側の可動接点５８を固定端子５９の接点面より開離させ、アンテナを無線通信部より切り離す。つまり可動接点５８と固定端子５９の接点面より構成される切換スイッチ部をオフ駆動するのである。
【００３１】
この同軸コネクタ部４の嵌合接続を解除すると、可動ばね板５６が弾性により復帰して可動接点５８が固定端子５９の接点面に弾接した図１（ａ）の状態に戻る。
【００３２】
尚図示する同軸コネクタ部４は外部導体９の先部に割り溝２７が形成され、また誘電体１３の先端面を外部導体９の先端面よりも奥に位置させるとともに、誘電体１３の先端より突出させた同軸ポスト５の先端面を外部導体９の先端面よりも外部に突出しないように奥内に位置させている。
【００３３】
（基本形態２）
上記基本形態１では接触突片５７の立設位置を可動ばね板５６の一端部と、他端部との間の略中央位置としているが、本基本形態は、図３に示すように接触突片５７の立設位置を可動ばね板５６の自由端である他端部寄り、つまり可動接点５８の近傍側としたものである。
【００３４】
つまり本基本形態では、可動ばね板５６の固定位置と接触突片５７の位置までの距離、つまりばね長Ｌを長くして、同軸プラグ部４の嵌合接続時に可動ばね板５６側に加わる応力の低減を図り、ばね折れや変形を防止している。
【００３５】
尚その他の構成は基本形態１と同じであるので、図示は省略する。
【００３６】
（基本形態３）
上記基本形態１，２では接触突片５７の上端を同軸ポスト５の先端が弾接する接触面としたが、接触突片５７に立設方向の力が接触突片５７に加わるため、可動ばね板５６に加わる応力が大きい。
【００３７】
そこで本基本形態３では接触突片５７の先端を図４に示すように逆Ｌ状に折り曲げて、その横片５７ａの板面を同軸プラグ部４の同軸ポスト５が弾接する接触面とし、この折り曲げにより接触突片５７に弾性を持たせて応力の分散を図っている。
【００３８】
つまり本基本形態も同軸プラグ部４の嵌合接続時に可動ばね板５６側に加わる応力の低減を図り、ばね折れや変形を防止している。
（基本形態４）
上記基本形態２，３では、可動接点５８の位置に接触突片５７の立設位置を近づけることで、応力の低減を図るようにしているが、基本形態３の接触突片５７のように応力の分散が図れる場合、図５の実線で示すように可動接点５８の位置から接触突片５７の立設位置を離しても良い。この場合接触突片５７が臨む外部電極体６０の嵌合凹部５５の孔５５ａの位置が可動接点５８の位置より離れることなり、同軸プラグ部４の同軸ポスト５の嵌合接続時に接触突片５７の横片５７ａを含む先部に付着した異物が孔５５ａを介してベース６１の内部に入っても可動接点５８までに到達せず、異物による動作不良の危険性が少なくなる。
【００３９】
尚その他の構成は基本形態１と基本的には同じであるので、図示は省略する。
【００４０】
（基本形態５）
本基本形態は更に応力の低減を図るために、図６に示すように可動ばね板５８の一端部と接触突片５７の立設位置までの距離を長くするために途中で、斜辺部５６ｃを折り曲げ形成しても良い。これにより可動ばね板５６の長さを長くすることができて、応力の低減が図れ、一層可動ばね板５６のばね折れや変形の防止が図れることになる。
【００４１】
尚その他の構成は基本形態４と基本的には同じであるので、図示は省略する。
（実施形態１）
上記基本形態５は可動ばね板５６に斜辺部５６ｃを折り曲げ形成してばね長を長くするようにしたものであるが、可動ばね板５６の一端部の水平部位と、可動接点５８を形成した水平部位の高さ位置が上下方向にずれるため、図７に示すように可動接点５８が固定端子５９の接点面に弾接している状態（同軸プラグ部４の非嵌合接続状態）で、接触突片５７の横片の板面が同軸ポスト５の軸方向に直交する平面となるように可動ばね板５６，接触突片５７を打ち抜き、曲げ加工したものを本実施形態では使用する。
【００４２】
図８（ａ）（ｂ）は打ち抜き、曲げ加工して得られた本実施形態に用いる可動ばね板５６の上面図、側面図を示す。この状態では可動接点５８が設けられた自由端側の片が斜め上向きとなって、可動ばね板５６の一端部側の板面の高さ位置と略同じ高さ位置となっている。またこの自由端側の板面に平行する接触突片５７の横片５７ａの板面も斜めとなっている。
【００４３】
このように形成された可動ばね板５６をベース６１に組み込むと、固定端子５９の接点面の高さ位置が、可動ばね板５６の一端部側の板面の高さ位置より低いため、可動接点５８が固定接点板５９の接点面５９に弾接した状態では、自由端側の部位が固定端子５９により押さえ込まれる状態となり、そのため接触突片５７の横片５７ａの板面が同軸プラブ部４の同軸ポスト５の軸方向に直交する平面となるように保持される。従って同軸プラグ部４の先部が外部電極体６の嵌合凹部５４に嵌合接続される際に、同軸ポスト５の偏心によって接触ポイントのずれが生じても安定した接触を保て、高周波特性が安定する。
【００４４】
尚同軸ポスト５に接触する接触突片５７の横片５７ａの板面部分は、可動ばね板５６を打ち抜く加工する際に用いる加工機のロール面側の板面であるようにする。つまり切断面に接触する場合に比べて安定した接触が可能となり高周波特性の安定化が図れる。この構成は基本形態３〜５の接触突片５７の横片５７ａに採用しても勿論良い。
【００４５】
更に同軸ポスト５の先端が接触する接触突片５７の横片５７ａの接触面に鏡面加工を施し、面粗度を上げることで接触面の平面度をより高くして安定した接触が得られるようにすれば、一層安定した高周波特性が得られる。この鏡面仕上げの構成は、基本形態３〜５の接触突片５７の横片５７ａに採用しても勿論良い。
【００４６】
（実施形態２）
本実施形態は実施形態１の構成において、図９に示すように接触突片５７の横片５７ａの先端を下向きに折り曲げ延長してその先部５７ｂを外部電極体６０の嵌合凹部５５の底面の孔５５ａを介してベース６１内に入れる構成としたものである。
【００４７】
このように構成することで、接触突片５７の剛性を高め、外部からの負荷（悪戯）に対して接触突片５７の変形防止を図っている。本実施形態の構成は上記の各基本形態に適用できる構成である。
【００４８】
【発明の効果】
請求項１の発明は、中心に同軸ポストを貫挿させた誘電体を筒状外部導体内に同心状に設け、上記誘電体の先端より突出する同軸ポストの先端を上記外部導体の先端面より奥側に位置させた同軸プラグ部の先端部が嵌合して上記外部導体が接触する嵌合凹部を表面側に設けた外部電極体と、該外部電極体の裏方に配設され、一端部側が固定されて他端部側を上記外部電極体方向に弾発させた可動ばね板と、上記外部電極体の裏方に配設され、上記可動ばね板の他端部側のばね付勢方向の面に設けられた可動接点が弾接する接点面を備えた固定端子と、上記可動ばね板に一体立設され、先部を上記外部電極体の嵌合凹部の底面に開口した孔より上記外部電極体の嵌合凹部内に臨ませ、該嵌合凹部に上記同軸プラグ部の先端部が嵌合されたときに同軸ポストの先端が上記先部に弾接する接触突片とを備え、上記接触突片の先部に上記同軸ポストの先端が弾接したときに上記可動ばね板が撓んで上記可動接点を上記固定端子の接点面から開離させるので、従来切り換えスイッチ部を構成する部材以外に必要であった同軸ポストと接触する別部品の可動接点部材が不要となって、部品点数を削減でき、製作コストが安価となるという効果がある。
【００４９】
また、上記可動ばね板は一枚の金属板の打ち抜き加工により形成されたものであって、上記可動接点を可動ばね板の板面に膨出形成するとともに、上記接触突片を切り起こしにより一体立設したので、部品コストが安価となり、一層の低コスト化が図れるという効果がある。
【００５０】
また、上記同軸ポストの先端と接触する接触突片の先部の接触面を打ち抜き加工時のロール面で形成したので、切断面に比べて接触性に優れ、高周波特性が一層安定するという効果がある。
【００５１】
請求項２の発明は、請求項１の発明において、上記接触突片の立設位置を上記可動接点近傍の位置としてあるので、同軸プラグ部の嵌合接続時に可動ばね板にかかる応力を低減でき、結果ばね折れや変形を防止できるという効果がある。
【００５２】
請求項３の発明は、請求項１の発明において、上記接触突片の先部が臨む外部電極体の嵌合凹部の底面に設けた孔の位置より上記可動接点を離したので、孔を介して異物（ゴミ）が入り込んでも、可動接点側に至ることがなく、異物侵入による動作不良の発生の恐れが無いという効果がある。
【００５３】
請求項４の発明は、請求項１又は２の発明において、上記接触突片にばね性を持たせたので、応力の分散が図れ、同軸プラグ部の嵌合接続時に可動ばね板にかかる応力を低減でき、結果ばね折れや変形を防止できるという効果がある。
【００５４】
請求項５の発明は、請求項１乃至４の何れかの発明において、上記可動ばね板の一端部側から接触突片の立設位置までの中間部位にばね長を長くする曲げ部位を設けてあるので、同軸プラグ部の嵌合接続時に可動ばね板にかかる応力を低減でき、結果ばね折れや変形を防止できるという効果がある。
【００５５】
請求項６の発明は、請求項１乃至５の何れかの発明において、上記同軸ポストの先端が接触する上記接触突片の先部を同軸ポストの軸方向に略直交する平面状に形成したので、同軸ポストの偏心によって接触ポイントのずれが生じても安定した接触を保つことができ、結果高周波特性が安定するという効果がある。
【００５６】
請求項７の発明は、請求項６の発明において、上記接触突片の先部の面を鏡面加工としたので、同軸ポストと接触する面の平面度をより高くすることができ、そのためより安定した接触が可能となって、高周波特性を一層安定化できるという効果がある。
【００５７】
請求項８の発明は、請求項１乃至７の何れかの発明において、上記接触突片の先部の先端を、上記外部電極体の嵌合凹部の孔を介して外部電極体の裏方に入れるように折曲したので、接触突片の剛性を高め外部からの負荷（悪戯）に対して変形防止の効果が図れるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a receptacle for a coaxial connector.
[0002]
[Prior art]
2. Description of the Related Art When a mobile phone is brought into a car and used, a hands-free kit and a device for fixing the mobile phone are provided so that the user can make a call without holding the mobile phone even when the mobile phone is fitted and operated. FIG. 10 shows a device A such as a hands-free kit and a mobile phone B. The device A is provided with a mounting portion 1A for mounting the mobile phone B on the upper surface of the housing 1, and the mounting portion 1A has a mounting portion 1A. It can be mounted and fixed by placing the back of the mobile phone B. Further, when the cellular phone B is placed and fixed on the placement portion 1A, the coaxial connector 2 provided on the placement portion 1A and the receptacle 3 provided on the back side of the portable phone B are fitted and connected, and the coaxial connector 2 is fitted and connected. Thus, in the receptacle 3, a circuit for disconnecting the antenna connection portion of the wireless communication unit on the mobile phone B side and the antenna on the mobile phone B side and simultaneously connecting the antenna connection portion to the coaxial connector 2 side is formed. The antenna connection portion of the wireless communication portion can be connected to the provided antenna via the coaxial cable C connected to the coaxial connector 2.
[0003]
FIG. 11 shows a state before fitting connection between the coaxial connector 2 and the receptacle 3 that are conventionally used. The coaxial connector 2 of this conventional example includes a coaxial plug portion 4 fitted to the receptacle 3 and a coaxial cable. A cable connecting portion 6 for connecting C to the coaxial post 5 of the coaxial plug portion 4 and an attaching portion 7 for attaching the coaxial connector 2 to the housing 1 are provided.
[0004]
The mounting portion 7 is fixed to the outer conductor 9 of the coaxial plug portion 4 at one end, and includes a coil spring 10 having a truncated cone shape fixed to the support member 8 fixed to the housing 1 at the other end. In order to limit the axial displacement of the tip portion of the coaxial plug portion 4 projecting outward from 1, the annular member 11 attached in the vicinity of the joint end with respect to the attachment portion 7 of the coaxial plug portion 4 is provided. Is accommodated in the mounting hole portion 12 formed in the housing 1, and the member 11 is brought into contact with the inner surface of the housing 1 around the opening of the mounting hole portion 12, so that the coaxial plug portion 4 is axially and radially oriented. Is held displaceably. Reference numeral 28 denotes a film body for preventing dust and the like from entering the mounting hole 12.
[0005]
The coaxial plug portion 4 includes a dielectric 13 having the coaxial post 5 provided in the center and the outer conductor 9 having the dielectric 13 provided therein.
[0006]
The cable connecting portion 6 includes a cylindrical body 22 having a through hole 21 for accommodating a conductor 20 housed in the center of the dielectric 19 of the coaxial cable C.

[0023]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to basic embodiments and embodiments.
( Basic form 1)
As shown in FIG. 1A, the receptacle 3 of this basic form includes an external electrode body 60, a synthetic resin molded product base 61 on which the external electrode body 60 is attached, a movable spring plate 56, a fixed terminal. 59 and the like.
[0024]
The base 61 is formed of a synthetic resin in a bottomed cylindrical shape, and the lower end of the peripheral wall of the external electrode body 60 is placed on the step formed outside the peripheral wall on the opening end side so that the external electrode body 60 is in the opening. To be attached.
[0025]
When the external electrode body 60 is disposed in a mounting hole provided in a case of a cellular phone or the like, the inner diameter of the surface facing the outer opening of the mounting hole gradually increases from the bottom toward the surface opening. A hole 54 is provided, and a fitting recess 55 for fitting the front end of the coaxial plug portion 4 of the coaxial connector 2 shown in FIG. The tip of a contact protrusion 57 that is integrally provided with a movable spring plate 56 provided in the base 61 is inserted into the fitting recess 55 through a hole 55 a at the bottom of the fitting recess 55. The tip of the tip of the contact protrusion 57 constitutes a contact surface with which the tip of the coaxial post 5 of the coaxial plug portion 4 fitted in the fitting recess 55 is elastically contacted.
[0026]
Here, the movable spring plate 56 is formed by punching a single hoop-shaped metal plate, and as shown in FIG. The terminal piece 56a is bent and extended, and the movable contact 58 is bulged and formed on the upper surface (in FIG. 1) of the other end portion by pressing or the like. A press-fit portion 56b provided at one end portion is formed on the peripheral wall of the base 61. By press-fitting into the provided groove 61a, one end is fixed to the base 61, and the other end, which is a free end, is repelled upward in the drawing. The tip of the terminal piece 56a is led out of the base 61 and connected to, for example, a radio circuit unit (not shown) of a mobile phone.
[0027]
The fixed terminal 59 is fixed to the peripheral wall by press-fitting a press-fit portion 59a formed in the intermediate portion into a groove 61b provided in the peripheral wall of the base 61. One end portion is inside the base 61 and the other end portion is outside the base 61. The lower surface of one end portion is disposed opposite to the movable contact 58 provided on the upper surface of the free end of the movable spring plate 56, and the contact surface on which the movable contact 58 is elastically contacted by the elastic spring plate 56 is constituted by the lower surface. is doing.
[0028]
The other end portion of the fixed terminal 59 constitutes a terminal portion connected to, for example, an antenna of a mobile phone, and the coaxial connector portion 4 is not fitted in the fitting recess 55 of the external electrode body 60 (FIG. 1A). The movable contact 58 of the movable spring plate 56 elastically contacts the contact surface of the fixed terminal 59, and a wireless communication unit (not shown) connected to the movable spring plate 56 and the antenna connected to the fixed terminal 59 are electrically connected. To be connected to.
[0029]
Thus, as shown in FIG. 1B, the front end of the coaxial plug portion 4 of the coaxial connector 2 is fitted and connected to the fitting recess 55 provided in the hole portion 54 of the external electrode body 60 of the receptacle 3 of this basic form. Then, the outer conductor 9 of the coaxial connector 2 contacts the outer electrode body 60 and the upper end of the contact protrusion 57 of the movable spring plate 56 in which the tip of the coaxial post 5 of the coaxial plug portion 4 protrudes into the fitting recess 55. The contact projecting piece 57 is pushed downward.
[0030]
As a result, the movable spring plate 56 bends around one end portion, the movable contact 58 on the free end side is separated from the contact surface of the fixed terminal 59, and the antenna is separated from the wireless communication portion. In other words, the changeover switch portion constituted by the contact surfaces of the movable contact 58 and the fixed terminal 59 is driven off.
[0031]
When the fitting connection of the coaxial connector portion 4 is released, the movable spring plate 56 is restored by elasticity, and the movable contact 58 returns to the state shown in FIG.
[0032]
In the illustrated coaxial connector portion 4, a split groove 27 is formed at the front portion of the outer conductor 9, and the front end surface of the dielectric 13 is located behind the front end surface of the outer conductor 9 and from the front end of the dielectric 13. The protruding end face of the coaxial post 5 is positioned in the back so as not to protrude outward from the leading end face of the outer conductor 9.
[0033]
( Basic form 2)
In the basic form 1, the standing position of the contact protrusion 57 is set at a substantially central position between one end and the other end of the movable spring plate 56. However, in this basic form, as shown in FIG. The standing position of the piece 57 is closer to the other end which is the free end of the movable spring plate 56, that is, near the movable contact 58.
[0034]
In other words, in this basic embodiment, the distance between the fixed position of the movable spring plate 56 and the position of the contact protrusion 57, that is, the spring length L is increased, and the stress applied to the movable spring plate 56 side when the coaxial plug portion 4 is fitted and connected. To reduce spring breakage and deformation.
[0035]
Since other configurations are the same as those of the basic form 1, illustration is omitted.
[0036]
( Basic form 3)
In the basic forms 1 and 2, the upper end of the contact protrusion 57 is the contact surface where the tip of the coaxial post 5 is elastically contacted. However, since a force in the standing direction is applied to the contact protrusion 57, the movable spring plate The stress applied to 56 is large.
[0037]
Therefore, in this basic form 3, the tip of the contact protrusion 57 is bent in an inverted L shape as shown in FIG. 4, and the plate surface of the lateral piece 57a is used as the contact surface where the coaxial post 5 of the coaxial plug portion 4 is elastically contacted. and to have a resilient contact protrusion 57 is aimed dispersion of stress by bending.
[0038]
That is, this basic form also reduces the stress applied to the movable spring plate 56 side when the coaxial plug portion 4 is fitted and connected, and prevents spring breakage and deformation.
( Basic form 4)
In the basic forms 2 and 3 described above, the stress is reduced by bringing the standing position of the contact protrusion 57 close to the position of the movable contact 58. However, as in the contact protrusion 57 of the basic form 3, the stress is reduced. 5 can be separated from the position of the movable contact 58 as shown by the solid line in FIG. In this case, the position of the hole 55a of the fitting recess 55 of the external electrode body 60 where the contact protrusion 57 faces is separated from the position of the movable contact 58, and the contact protrusion 57 when the coaxial post 5 of the coaxial plug part 4 is fitted and connected. Even if foreign matter adhering to the tip including the horizontal piece 57a enters the inside of the base 61 through the hole 55a, it does not reach the movable contact 58, and the risk of malfunction due to foreign matter is reduced.
[0039]
Since the other configuration is basically the same as that of the basic form 1, the illustration is omitted.
[0040]
( Basic form 5)
In this basic form, in order to further reduce the stress, as shown in FIG. 6, in order to increase the distance from the one end portion of the movable spring plate 58 to the standing position of the contact protrusion 57, the hypotenuse portion 56c is provided on the way. Bending may be formed. As a result, the length of the movable spring plate 56 can be increased, the stress can be reduced, and the movable spring plate 56 can be further prevented from being bent or deformed.
[0041]
Since the other configuration is basically the same as that of the basic form 4, the illustration is omitted.
(Embodiment 1 )
In the basic form 5, the slanted side portion 56c is bent and formed on the movable spring plate 56 so as to lengthen the spring length. However, the horizontal portion at one end of the movable spring plate 56 and the horizontal portion where the movable contact 58 is formed. Since the height position of the part is shifted in the vertical direction, the contact point is in a state where the movable contact 58 is in elastic contact with the contact surface of the fixed terminal 59 (non-fitted connection state of the coaxial plug portion 4) as shown in FIG. In the present embodiment, the movable spring plate 56 and the contact protrusion 57 are punched and bent so that the plate surface of the horizontal piece 57 is a plane orthogonal to the axial direction of the coaxial post 5.
[0042]
8A and 8B are a top view and a side view of the movable spring plate 56 used in the present embodiment obtained by punching and bending. In this state, the piece on the free end side where the movable contact 58 is provided is obliquely upward, and the height position is substantially the same as the height position of the plate surface on the one end portion side of the movable spring plate 56. The plate surface of the lateral piece 57a of the contact protrusion 57 parallel to the plate surface on the free end side is also inclined.
[0043]
When the movable spring plate 56 formed in this way is incorporated in the base 61, the height position of the contact surface of the fixed terminal 59 is lower than the height position of the plate surface on the one end portion side of the movable spring plate 56. In a state in which 58 is in elastic contact with the contact surface 59 of the fixed contact plate 59, the free end portion is pressed by the fixed terminal 59. Therefore, the plate surface of the lateral piece 57 a of the contact protrusion 57 is the same as that of the coaxial plug portion 4. It is held so as to be a plane orthogonal to the axial direction of the coaxial post 5. Therefore, when the tip of the coaxial plug portion 4 is fitted and connected to the fitting recess 54 of the external electrode body 6, even if the contact point is displaced due to the eccentricity of the coaxial post 5, stable contact is maintained and high frequency characteristics are maintained. Is stable.
[0044]
The plate surface portion of the lateral piece 57a of the contact protrusion 57 that contacts the coaxial post 5 is made to be the plate surface on the roll surface side of the processing machine used when the movable spring plate 56 is punched. That is, a stable contact is possible compared with the case of contacting the cut surface, and high frequency characteristics can be stabilized. Of course, this configuration may be adopted for the lateral piece 57a of the contact protrusion 57 of the basic forms 3 to 5.
[0045]
Further, the contact surface of the horizontal piece 57a of the contact protrusion 57 with which the tip of the coaxial post 5 contacts is mirror-finished to increase the surface roughness so that the flatness of the contact surface can be increased and stable contact can be obtained. If so, more stable high-frequency characteristics can be obtained. Of course, this mirror-finished configuration may be adopted for the horizontal piece 57a of the contact protrusion 57 of the basic forms 3 to 5.
[0046]
(Embodiment 2 )
In the present embodiment, in the configuration of the first embodiment, as shown in FIG. 9, the tip of the lateral piece 57 a of the contact protrusion 57 is bent downward and extended, and the tip 57 b is the bottom surface of the fitting recess 55 of the external electrode body 60. This is configured to be inserted into the base 61 through the hole 55a.
[0047]
By configuring in this way, the rigidity of the contact protrusion 57 is increased, and the deformation of the contact protrusion 57 is prevented against a load (mischief) from the outside. The configuration of the present embodiment is a configuration applicable to each of the above basic modes.
[0048]
