【０００２】
【従来の技術】
図３はかかる衛星放送受信用コンバータの従来例を示す分解斜視図であり、この衛星放送受信用コンバータ５１は、互いに結合・一体化されて筐体を形成する上ケース５２及び下ケース５３と、これら上・下ケース５２，５３の内部に収納されたコンバータ本体とで構成されており、上・下ケース５２，５３には、結合・一体化された際に筒部を形成する小径部５２ａ，５３ａ及び大径部５２ｂ，５３ｂが各々形成されている。一方、前記コンバータ本体は、ダイキャストフレーム５４を有し、このダイキャストフレーム５４は、内部中空の筐体部５４ａと、この筐体部５４ａの一側面に連設された小筒部５４ｂと、この小筒部５４ｂの一端部に一体に形成された大筒部５４ｃとから構成され、筐体部５４ａの他側面側は開放されている。そして、これら筐体部５４ａと小筒部５４ｂと大筒部５４ｃとはその内部が各々連通されており、大筒部５４ｃの一端部には、リング状のゴムパッキン５５が挿通されてカップ状の防水キャップ５６が嵌め込まれている。
【０００３】
また、前記コンバータ本体は、アンテナ部材としてのプローブ５７を支持するプリント回路基板５８と、このプリント回路基板５８に形成された回路部（不図示）を収納するダイキャストカバー５９と、このダイキャストカバー５９に貼付されるメタルカバー６０を有し、これらプリント回路基板５８とダイキャストカバー５９及びメタルカバー６０は重ね合わされ、プローブ５７を筐体部５４ａ内に位置させた状態で取付ねじ６１によりダイキャストフレーム５４に固定されている。そして、前記コンバータ本体は、防水キャップ５６を大径部５２ｂ，５３ｂから外方へ突出させて上・下ケース５２，５３の内部に収納されている。

【００１５】
前記コンバータ本体は、合成樹脂製のプリント回路基板１９と、プリント回路基板１９を取り付けるメタルフレーム２４と、メタルフレーム２４に取り付けられるメタルカバー３４とが一体に構成されて成っている。
【００１６】
プリント回路基板１９は、その一方の面に角形の切欠部２０ａを有する銅箔２０が形成されており、この切欠部２０内にアンテナ部材としての銅箔製のパッチアンテナ２１が印刷やエッチング等により４つ設けられている。また、プリント回路基板１９の他方の面には、抵抗やコンデンサ等の電気素子を備えた回路部２２が形成されており、この回路部２２とパッチアンテナ２１とは図示せぬスルホールを介して接続されている。また、プリント回路基板１９の左右両縁部には、係合切欠２３が形成されている。
【００１７】
メタルフレーム２４は、鉄製平板等の導電性を有する板金から４角枠状に形成され、上板部２５と下板部２６及び側板部２７，２８とを備えており、側板部２７，２８の一端面には係合突起２９が形成されている。このメタルフレーム２４内は、上板部２５と側板部２７，２８とを連結する連結板３０と、下板部２６と側板部２７，２８とを連結する連結板３１とによって複数に分割されている。また、下板部２６には同軸線３２が支持されており、この同軸線３２には封止材としてのリング状のゴムパッキン３３が嵌め込まれている。そして、このメタルフレーム２４の一端面側には、係合突起２９にプリント回路基板１９が係合切欠２３を係合させて取り付けられており、同軸線３２が回路部２２と接続されて、パッチアンテナ２１がメタルフレーム２４の外方に露出した状態となっている。
【００１８】

【００１９】
次に、このように構成された衛星放送受信用コンバータ１の組立方法を説明すると、先ず、係合切欠２３を係合突起２９に係合させて、銅箔２０及びパッチアンテナ２１と回路部２２とが形成されたプリント回路基板１９をメタルフレーム２４の一端面側に取り付け、メタルフレーム２４の下板部２６に支持された同軸線３２と回路部２２とを半田付けにより接続する。次に、同軸線３２にゴムパッキン３３を嵌め込み、次いで、メタルカバー３４の内部にメタルフレーム２４の上・下板部２５，２６及び側板部２７，２８の各々他端面側を位置させて、半田付けやかしめ等の適宜手段によってメタルカバー３４をメタルフレーム２４の他端面側に取り付け、前記コンバータ本体の組立が完了する。
【００２０】
次に、ゴムパッキン１０を第１のケース２の溝部８に切欠部１１ａ，４ａ同士を対応させて嵌め込み、次いで、前記コンバータ本体を第１のケース２内に収納し、ゴムパッキン３３を切欠部４ａ上に載置して同軸線３２を第１のケース２から突出させる。しかる後、第２のケース１２を第１のケース２に切欠部１４ａ，４ａ同士を対応させて組み合わせると、初めフック部１８の先端部が第１のケース２の上・下壁部３，４及び側壁部５，７の各々端面にぶつかった状態となり、この状態で更に第２のケース１２を押し込むと第２のケース１２の弾性によってフック部１８が内方に撓み、フック部１８の先端部が係合凹部９に位置したときにフック部１８は元の状態に復帰し、フック部１８が係合凹部９に掛け止めされて第１，第２のケース２，１２が互いに結合・一体化される。
【００２１】
このようにして衛星放送受信用コンバータ１の組立は完了するが、組立後においては、前記コンバータ本体が第１，第２のケース２，１２内に収納されてパッチアンテナ２１が第２のケース１２の薄肉部１６ａと対向し、また、第２のケース１２の上・下壁部１３，１４及び側壁部１５，１７の各端面がゴムパッキン１０に圧接するとともに、切欠部１４ａがゴムパッキン３３に押圧した状態で当接し、ゴムパッキン１０，３３を圧縮させて第１，第２のケース２，１２内が密封された状態となっている。
【００２２】
しかして、このように組み立てられた衛星放送受信用コンバータ１は、図示を省略した皿状のパラボラアンテナに取り付けられ、このパラボラアンテナを介して衛星電波が、第２のケース１２の薄肉部１６ａを貫通しパッチアンテナ２１にて受信され、こうして得られた受信信号が回路部２２で増幅・周波数変換されて同軸線３２から導出され、テレビやビデオ等の図示せぬ受信機に入力される。
【００２３】
そして、回路部２２は、その周囲全体がプリント回路基板１９の一方の面に形成された銅箔２２とメタルフレーム２４とメタルカバー３４とによって覆われているので、衛星放送受信用コンバータ１の外部からのノイズを遮蔽でき、この外部ノイズによる影響を受けることなく安定且つ正確な動作ができるようになっている。
【００２４】
【発明の効果】
本発明は、以上説明したような形態で実施され、以下に記載されるような効果を奏する。
【００２５】
プリント回路基板と、このプリント回路基板に設けられ、パラボラアンテナを介して衛星電波を受信するアンテナ部材とを備え、このアンテナ部材を導電箔からなるパッチアンテナで構成し、前記アンテナ部材を前記プリント回路基板の一方の面に形成したので、ダイキャストフレームを用いなくとも衛星電波を受信することを可能となし、コストを低減できる衛星放送受信用コンバータを提供することができる。この場合、前記アンテナ部材の形成に際し、印刷やエッチングを用いると、前記アンテナ部材を前記プリント基板に簡単に形成でき、コスト低減に有効である。
【００２６】
また、前記プリント回路基板を取り付けるメタルフレームと、このメタルフレームに取り付けられるメタルカバーとを備え、前記メタルフレームの一端面側に前記プリント回路基板を前記アンテナ部材が外方に露出された状態で取り付けるとともに、前記メタルフレームの他端面側に前記メタルカバーを取り付けて、前記プリント回路基板と前記メタルフレームと前記メタルカバーとを一体に構成すると、前記衛星放送受信用コンバータの組立工程において、前記プリント回路基板と前記メタルフレームと前記メタルカバーとを一部品として扱うことができ、取り扱い易くなるため生産性を向上させることができる。
【００２７】
さらに、互いに結合・一体化されて筐体を形成する合成樹脂製の第１，第２のケースを備え、この第２のケースに薄肉部を形成し、前記プリント回路基板と前記メタルフレームと前記メタルカバーとを前記第１，第２のケース内に収納して前記アンテナ部材と前記薄肉部とを対向させ、前記第１，第２のケース内を密封すると、前記薄肉部を通して前記アンテナ部材が衛星電波を受信でき、前記アンテナ部材の受信感度を向上させることができるとともに、前記第１，第２のケース内への粉塵や水滴等の異物の侵入を防止でき、この異物による影響を受けることなく安定且つ正確に前記アンテナ部材が前記衛星電波を受信できる。

The rubber seals 10 and 33 are compressed in contact with each other in a pressed state, and the first and second cases 2 and 12 are sealed.
[0022]
Thus, the satellite broadcast receiving converter 1 assembled in this way is attached to a dish-shaped parabolic antenna (not shown), and the satellite radio wave passes through the thin portion 16a of the second case 12 via the parabolic antenna. The signal is passed through and received by the patch antenna 21, and the received signal thus obtained is amplified and frequency-converted by the circuit unit 22, derived from the coaxial line 32, and input to a receiver (not shown) such as a television or a video.
[0023]
Since the entire periphery of the circuit unit 22 is covered with the copper foil 22, the metal frame 24, and the metal cover 34 formed on one surface of the printed circuit board 19, the outside of the satellite broadcast receiving converter 1 is covered. Noise can be shielded, and stable and accurate operation can be performed without being affected by the external noise.
