Description

【０００１】
【発明の属する技術分野】
本発明は、アンテナ取付構造を備えた電子機器に係り、より詳細には電子機器の本体から収納自在に出し入れされるアンテナの取り付け構造を備えた電子機器に関する。ここで電子機器とは、携帯電話機、携帯無線機、ＰＨＳ、トランシーバ、モバイル端末、コードレス電話、ラジオ等をいう。
【０００２】
【従来の技術】
図３は本発明によるアンテナ取付構造を備えた電子機器の内部説明図であり、図４は図３で示すアンテナ取付構造の要部を示す説明図であるが、従来のアンテナ取付構造を備えた電子機器もまた同様である。そして、図５は従来のアンテナ取付構造を示す説明図である。
【０００３】
本発明では電子機器の範疇に属する一つの例として、携帯電話機等の移動体端末機器を取り上げており、図３〜図５に示すようなアンテナ取付構造を備えている。アンテナ４を使用しない時には、アンテナ４は機器本体１内に収納されている。アンテナ４を収納するアッセンブリー６は、取付金具２とアンテナ端子３とアンテナチューブ５とから構成される。アンテナ端子３は取付金具２に装着するように係止され、取付金具２はアンテナ収納側端部にある管状口元部２１で弾力性のあるアンテナチューブ５と接合されている。アンテナチューブ５は、アンテナロッド４ａを内部に挿通してアンテナ長手方向に収納する弾性チューブ体であり、機器本体１に内設されている。
【０００４】
図５は従来のアンテナ取付構造を示す説明図であり、アンテナ端子３が取付金具２に装着して係止される様子を示している。図５（１）は斜視図、図５（２）はその側面図、図５（３）は係止される前のアンテナ端子３と取付金具２とを示す側面図である。
取付金具２は、中心にアンテナ４の挿通案内孔２Ａが内設されており、アンテナ軸心から左右に略対称で、略八角形断面をなしている。アンテナ延伸側及び収納側の端部には、取付金具係止部（２ｅ，２ｇ）を突設させており、アンテナ端子３の側面係止部（３ｅ，３ｇ）と係合する。取付金具係止部２ｅはアンテナ軸心に対称にアンテナ収納側に一対設けられており、アンテナ延伸側にもさらに一対の取付金具係止部２ｇが設けてある。アンテナ延伸側もしくは収納側のいずれか一方だけでもよいが、両方にあった方が係合が安定して性能がよくなる。そして、取付金具２は、アンテナ軸心から左右に略対称の略八角形断面を有するが、外面としては、上外面２ｂ、上斜面２ｃ、外側面２ａ、下斜面２ｄ、底面２ｋの各面を有する。一方、アンテナ端子３は逆凹形の断面を有し、内面としては、上内面３ｂ、上斜面３ｘ、内側面３ａ、の各面を有する。
【０００５】
取付金具２とアンテナ端子３との係合にあたっては、取付金具２各外面とアンテナ端子３各内面とが面で接触するように一体的に係合される。すなわち、取付金具２の外側面２ａとアンテナ端子３の内側面３ａとが接面し、取付金具２の上外面２ｂとアンテナ端子３の上内面３ｂとが接面し、また、取付金具２の上斜面２ｃとアンテナ端子３の上斜面３ｘとが設面する。そして、取付金具２に突設された取付金具係止部２ｅの下端面２ｆと、アンテナ端子３に突設された側面係止部３ｅの上端面３ｆとが互いに係止し合うことで、アンテナ端子３が取付金具２に装着されるように係合させられる。この図５（１）〜５（３）に見られる従来のものについては、空隙等はなるべく設けることなく、密着した構成にすることが望まれていた。
【０００６】
図５（３）に示される寸法Ａ及びＢについては、Ａは取付金具２の上外面２ｂと突設された取付金具係止部２ｅの端面２ｆとの設計寸法であり、Ｂはアンテナ端子３に突設された側面係止部３ｅの上端面３ｆと上内面３ｂとの設計時における寸法である。
ここで、従来の設計管理のやり方によると、Ａ＝Ｂとして，Ａの寸法交差を０〜−０．０５ｍｍ、Ｂの寸法交差を０〜＋０．０５ｍｍ、としていたため、ＢはＡよりも大きくなる場合が多くなり、アンテナ端子３とは取付金具２の取付けは、ガタが出やすい設計寸法の設定となっていた。
【０００７】
また、図４には、アッセンブリー６を機器本体１内のケース部１Ａに組み込む様子を示す。ケース部１Ａは、機器本体１に内設され、アンテナ４を収容するアッセンブリー６を組み込む時の組込み用ケースであり、ケース部１Ａの内側には複数のリブ１ａが設けられており、ガタつきなくしっかりと保持する構造となっている。ところが、アンテナ端子３の下端面３ｉにはエッジ辺部３ｊを有しているため、組みたての際エッジ辺部３ｊはこれらのリブ１ａに引っ掛かり易い。
【０００８】
【発明が解決しようとする課題】
しかしながら、従来のアンテナ取付構造を備えた電子機器においては、先に述べた構造となっていたので、機器製造に当たり特にその組み立て作業には、次のような課題がある。
１）アンテナ端子３とは取付金具２の取付けでガタが発生すると、接触が不安定になり、アンテナの受信感度がばらつく。
２）従来のアンテナ端子３、取付金具２等を組み立て、アッセンブリー６として機器本体１内ケースに取り付ける際、アンテナ端子３のエッジ辺部３ｊが機器本体１内ケースのリブ１ａに引っ掛るため組み立て作業がやりにくく、改善が必要である。
そこで、アンテナ取付構造を備える電子機器を組み立てるに当たり、アンテナ端子３とは取付金具２とのガタをなくす取付構造とし、アンテナ端子３と取付金具２とのアッセンブリー６を機器本体１内ケースに取り込み易くする構造とし、作業が面倒で熟練が必要で多くの手間がかかった従来の構造を改良し、作業者が容易に誰でも組み立てられ、性能的にも向上したアンテナ取付構造を備えた電子機器を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明は上述の課題を解決した次のようなものである。
ひとつには、伸縮自在で機器本体１内に収納されるアンテナ４と、このアンテナ４の挿通案内孔２Ａが内設された左右対称略八角形断面の取付金具２と、この取付金具２に装着され係止される断面逆凹形のアンテナ端子３とを有するアンテナ取付構造を備えた電子機器にあって、この取付金具２の外側面２ａとこのアンテナ端子３の内側面３ａとを接面させ、この取付金具２の上外面２ｂとこのアンテナ端子３の上内面３ｂとを接面させ、さらに前記取付金具の上斜面２ｃとアンテナ端子３の内角部３ｃとは空隙を設けて係合させたアンテナ取付構造とした。
その次には、伸縮自在で機器本体内１に収納されるアンテナ４と、このアンテナ４の挿通案内孔２Ａが内設された左右対称略八角形断面の取付金具２と、この取付金具２に装着され係止される断面逆凹形のアンテナ端子２とを有するアンテナ取付構造を備えた電子機器にあって、この取付金具２の外側面２ａとこのアンテナ端子３の内側面３ａとを接面させ、このアンテナ端子３の外側面３ａを延面折曲して端子延長面３ｄを形成し、この端子延長面３ｄとこの取付金具２の下斜面２ｄとを係合させたアンテナ取付構造とした。
【００１０】
【発明の実施の形態】
以下、図１〜図４を参照して本発明によるアンテナ取付構造を備えた電子機器の実施の形態を詳細に説明する。図１は本発明によるアンテナ取付構造の要部を示す斜視図及び側面図であり、また、図２は本発明によるアンテナ取付構造の他の実施の形態の要部を示す斜視図及び側面図である。さらに、図３は本発明によるアンテナ取付構造を備えた電子機器の内部説明図であり、図４は図３で示すアンテナ取付構造の要部を示す説明図である。
【００１１】
図１に示すように、本発明のアンテナ取付構造を備えた電子機器は、伸縮自在で機器本体１内に収納されるアンテナ４と、このアンテナ４を挿通案内するアンテナ挿通案内孔２Ａを中心として左右略対称八角形断面の取付金具２と、この取付金具２に装着されるようにして係止される断面逆凹形のアンテナ端子３とを有する。取付金具２とアンテナ端子３との係合は、取付金具２に突設された取付金具係止部２ｅの下端面２ｆと、アンテナ端子３に突設された側面係止部３ｅの上端面３ｆとが互いに係止し合うことでなされる。端面どおしの係止構造は、図１及び図２においては、アンテナを収納する側（下端面２ｆと上端面３ｆ）及びアンテナを延伸する側（下端面２ｈと上端面３ｈ）の両方に、しかもアンテナの中心軸方向に対称にして設定されている。端面の係止構造は、アンテナを収納する側またはアンテナを延伸する側のいずれか１箇所に一対設けてもよいし、アンテナを収納する側及びアンテナを延伸する側の両方に一対ずつ設けてもよい。
【００１２】
図１に見られるように、本発明のアンテナ取付構造を備えた電子機器は、取付金具２の外側面２ａとアンテナ端子３の内側面３ａとを接面させ、取付金具２の上面２ｂとこのアンテナ端子３の上内面３ｂとを接面させ、さらに前記取付金具の上斜面２ｃとアンテナ端子３の内角部３ｃとは空隙１０を設けて係合させている。本発明のポイントの一つは、空隙１０を設けたことである。この空隙１０は、取付金具２の上斜面２ｃとアンテナ端子３の内角部３ｃとで得られる隙間である。従来における面どおしを接触させるやり方はここでは採用せず、アンテナ端子３のコーナー部にあたる内角部３ｃを鋭角状に折曲させ、取付金具２の上斜面２ｃとの間でスペースを生じさせたものである。
【００１３】
図２の右側の図は、アッセンブリー６を機器本体１内のケース部１Ａに組み込むときの様子を示しており、ケース部１Ａは複数のリブ１ａを有する。図２に示す寸法Ａは取付金具２の上面２ｂと突設された取付金具係止部２ｅの下端面２ｆとの設計寸法であり、寸法Ｂはアンテナ端子３に突設された側面係止部３ｅの上端面３ｆと上内面３ｂとの設計寸法である。
ここで、本発明における効果的な寸法設定の一例を示せば、Ｂ＝Ａ−０．１ｍｍとし、Ａの寸法交差を０〜＋０．０５ｍｍ、Ｂの寸法交差を０〜−０．０５ｍｍ、とするのが良い。このようにして、取付金具２とアンテナ端子３との間で隙間ができるようにすることで、アンテナ端子３にバネ性を多く持たせて、ガタをなくすようにした。
【００１４】
図２における要点は、アンテナ端子３のエッジ辺部３ｊが機器本体１内ケースのリブ１ａに引っ掛かりにくくするように改良を施したことである。ここでは、この取付金具２の外側面２ａとこのアンテナ端子３の内側面３ａとを接面させ、このアンテナ端子３の外側面３ａを延面折曲して端子延長面３ｄを形成し、この端子延長面３ｄとこの取付金具２の下斜面２ｄとを係合させた。折曲して端子延長面３ｄを形成する場合は、折曲辺はエッジ状に鋭角にならないようにし、なるだけ緩やかなＲにするのがよい。エッジが飛び出てこないので、リブ１ａに引っ掛かることがなく、スムーズな組み入れができる。また、取付金具２の下斜面２ｄと端子延長面３ｄとが面接触するようにすれば、ますます端部が飛び出さず、電気的接触がよくなり性能も安定する。
【００１５】
【発明の効果】
このように本発明によれば、次のような優れた効果を発揮する。
・取付金具とアンテナ端子との間でのガタつきがなくなったので、接触が安定し、アンテナの受信感度のバラつきがなくなり、性能が向上した。
・アンテナのアッセンブリーの組み立て工程において、アンテナ端子のエッジが収納ケースに引っ掛かることがなくなり、組み立て作業性が良くなり、構造的にも安定し性能的にも向上した。
