Description

【考案の詳細な説明】 本考案はテレビジョンなどに用いる電子同調型チューナ
の構造に関する。
テレビジョンに用いるｔＪＨＦ電子同調型チューナは、
箱状の金属ケースの中をシールド板で仕切って小室を設
け、これら小室の中にトランジスタや抵抗などの電子部
品を配設するほか、分布定数回路の同調素子を配設する
。
第１図は従来型のＩＪＨＦ電子同調チューナの内部を示
す斜視図、第２図はその断面図であり、図中１は金属ケ
ース、２は金属ケース１内を仕切るシールド板、３は共
振回路を構成するライン棒、４はライン棒３の一端に接
続されたバラクタダイオード、５はライン棒３の他端に
接続された終端コンデンサ、６は抵抗で、バラクタダイ
オード４に加７える電圧源と共振回路の間を高周波的に
しゃ断するものである。
７は底板である。
底板７は、第２図に示すように、２枚の上面プリント配
線板７ａと下面プリント配線板７ｂを背中合せに重ね、
その間を接着剤８で接着している。
７０〜７ｅは配線層で、このうち配線層７ｃはバラクタ
ダイオードへの電圧印加用配線層、７ｄは抵抗６とライ
ン棒３とを接続する配線層、７ｅはアース配線層である
。
上述の如き従来のＵＨＦチューナは、２枚の上下面プリ
ント配線板を重ね合せているので、上面プリント配線板
７ａの厚さ分だけチューナの高さが大きくなるし、また
、バラクタダイオードのアース側の残留インダクタンス
が大きくなり周波数の可変範囲が小さくなって、結果と
して終端容量を大きくしなければならず、共振回路のＱ
が低下する。
このほか、特にＵＨＦ回路では、温度、湿度の影響を受
けた場合に、プリント配線板７ａの絶縁板の誘電率が変
化して、共振周波数が変動するなどの不都合を生じる。
本考案は上述の如き従来の欠点を改善する新規な考案で
あり、その目的は共振回路の共振周波数が温度や湿度の
影響を受けることなく、又共振回路の浮遊インダクタン
スが少なくかつ小型に構成できるような電子同調型チュ
ーナを提供することにある。
次に本考案の一実施例を、図面を用いて詳細に説明する
。
第３図は１７′２ｔｌ長共振器の実施例を示す断面図で
ある。
同図において、９はアース補強板である。
アース補強板９は上面が平担に形成され、端縁には折曲
された複数の接続片９ａ、９ｂが形成されている。
又、上面の一部には、バラクタダイオード４のアース側
端子が挿通ずる穴９ｃが設けられ、その内縁から下方に
フランジ９ｄがしぼり加工にて形成されている。
なお、実施例において従来装置と同一部分には同一符号
を付し、その説明は省略する。
本考案において、上面プリント配線板７ａは、終端コン
デンサ５からバラクタダイオード４部分までの共振回路
を構成する部分（切欠き部）が切取られ、代って、その
部分に金属製の補強板９が取付けられている。
この第１実施例の共振回路図を第４図に示す。
第５図は１７＃長共振器の実施例を示す断面図であり、
前記実施例及び従来例と同一部分には同一符号を付しそ
の説明は省略する。
この実施例においても上面プリント配線板７ａは、共振
回路を構成する部分が切取られ、代ってその部分に金属
製の補強板９が前記実施例と同様に取付けられている。
第６図に第２実施例の回路図を示す。以上詳細に説明し
たように、本考案は共振回路部分の上面プリント配線板
を切り取っているので、厚みを従来のものより薄型に形
成できる。
又、上面プリント配線板を切取った部分に金属製のアー
ス補強板を設けているので、共振回路近くに、該回路に
影響を及ぼすような誘電体部分がなく、温度・湿度の変
化による周波数変動が従来のものに比べて非常に少なく
なった。
又、アース補強板により機械的な強度も大きくなった外
、バラクタダイオードのアース側端子の残留インダクタ
ンスが小さくできるので、共振回路の周波数変化範囲も
大きくとれ、結果的に共振回路のＱを大きくすることが
できるなど、多くの効果を有するものである。
【図面の簡単な説明】
第１図及び第２図は従来のチューナの部分的な斜視図と
断面図、第３図は本考案の第１実施例を示す断面図、第
４図は同回路図、第５図は本考案の第２実施例を示す断
面図、第６図は同回路図である。 図中、１は金属ケース、２はシールド板、３はライン棒
、４はバラクタダイオード、５は終端コンデンサ、６は
抵抗、７は底板、７ａは上面プリント配線板、７ｂは下
面プリント配線板、７０〜７ｅは配線層、８は接着剤、
９はアース補強板である。
