【0008】
【発明の実施の形態】
本発明の一実施形態の高周波信号開閉装置は、高周波リレーであり、図1乃至図3に基づいて以下に説明する。
【0009】
1 は金属製のベースで、略直方体状に形成され、その長手方向の両端部及び中央部には、一方面1aから他方面1bへ貫通する貫通孔1cが設けられている。この貫通孔1cには、ガラス等の絶縁体2 が同心円状に外方面に付設された棒状の3本の固定端子、詳しくは、常開固定端子3a, 共通固定端子3b, 常閉固定端子3cが、それぞれ貫通固定される。これらの固定端子3a,3b,3cは、貫通孔1cの内縁部との間に絶縁体2 が位置することとなって、絶縁状態で貫通固定される。このベース1 は、その他方面1b側にアース端子4 が埋め込まれる埋込穴(図示せず)が設けられ、その埋め込まれたアース端子4 によって、例えば、実装されるプリント基板(図示せず)にアースされることとなる。5 は金属製のシールド部材で、ベース1 の一方面に配置される配置部5aを有している。この配置部5aは、固定端子3a,3b,3cの周囲に切除部5bが設けられている。この金属製のシールド部材5 は、ベース1 、絶縁体2 、固定端子3 及びアース端子4 と共に、固定端子ブロック20を構成する。
【0010】
6 は鉄芯で、その両端部がコイルボビン7 からそれぞれ突出する状態でそのコイルボビン7 に貫通固定され、そのコイルボビン7 に仕切られた範囲にコイル8 が巻回されることによって、突出した一端部の両側が磁極部6a,6b となり、突出した他端部(図示せず)に、鉄芯6 と共に磁路を成す継鉄9 がかしめ固定される。この継鉄9 は、鉄芯6 と平行に、図1に示すように、コイル8 の側方及び下方で延伸され、コイル8 の側方で延伸された一端側の先端部9aが鉄芯6 の一方磁極部6aと対向し、コイル8 の下方で延伸されて更に上方に延設されたた他端側の先端部9bが鉄芯6 の他方磁極部6bと対向する。この継鉄9 は、鉄芯6 、コイルボビン7 及びコイル8 と共に、電磁石ブロック30を構成する。
【0011】
10はカードで、成形材料により、略直方体状に形成され、その長手方向一端部に貫通孔10a が設けられ、その貫通孔10a に、互いの間に永久磁石11を介在させた一対の接極子12a,12b が配設されて、一方接極子12a が鉄芯6 の一方磁極部6aと継鉄9 の一端側の先端部9aとの間に位置し、他方接極子12b が鉄芯6 の他方磁極部6bと継鉄9 の他端側の先端部9aとの間に位置するようになる。
【0012】
13a,13b はいずれも可動接触片で、導電金属板材よりなり、長手方向の両端部が2つに分岐している。これらの可動接触片13a,13b は、カード10の本体部分からそれぞれ延設された支持部10b により中央部がそれぞれ一体成形されることによって、中央部から延伸された両端部が固定端子3 に接離するよう、カード10に支持されている。これらの可動接触片13a,13b は、組み立てられた状態では、配置部5aから立設されるとともに各固定端子3a,3b,3cを包囲するよう延設されて配置部5aと共にシールド部材5 を成す板状の包囲部5cに包囲される。この包囲部5cは、ベース1 とは反対側から切欠部5dが切り欠かれている。
【0013】
14は平衡ばねで、図1に示すように、平面視で略四辺形状に形成され、その長手方向の一端側が、平衡ばね保持板15に保持されるとともに、長手方向中央から他端14b にかけて、カード10の他端側の側面及び中央部上面に、そのもののばね力でもって沿った状態で配設される。この平衡ばね14は、カード10、永久磁石11、両接極子12a,12b 、可動接触片13及び平衡ばね保持板15と共に、可動接触片ブロック40を構成する。
【0014】
16は基台で、一方が開口した箱状に形成され、固定端子ブロック20を配設する固定端子ブロック配設部16a 、電磁石ブロック30を配設する電磁石ブロック配設部16b 、可動接触片ブロック40の平衡ばね保持板15を挿入して支持する平衡ばね保持板支持部16c がそれぞれ設けられ、ケース17が開口側から被嵌される。
【0015】
次に、動作を説明する。コイル8 に通電して励磁すると、一方接極子12a が鉄芯1 の一端磁極部1aに吸引されるとともに、他方接極子12b が継鉄9 の他端側の先端部9bに当接して閉磁路が形成される。このとき、カード10は、一端側が平衡ばね保持板15によって保持された平衡ばね14のばね力に抗して、両接極子12a,12b の動作に連動して平行移動する。この平行移動の際、カード10の支持部10b は、シールド部材5 の包囲部5cに設けられた切欠部5dを通過する。
【0016】
こうして、カード10が平行移動そうすると、図2(a) に示すように、常開固定端子3a及び共通固定端子3bに、一方可動接触片13a の両端部がそれぞれ接触するとともに、常閉固定端子3c及び共通固定端子3bから、他方可動接触片13b の両端部がそれぞれ開離して、シールド部材5 の板状の包囲部5cが折曲されて可動接触片の延伸方向に沿って設けられた接触部5eに接触する。このように、両可動接触片13a,13b が3本の固定端子3a,3b,3cに接離することによって、高周波信号が開閉される。
【0017】
そして、コイル8 の通電を停止して励磁しなくなると、前述とは逆に、他方接極子12b が鉄芯1 の他端磁極部1bに当接するとともに、一方接極子12a が継鉄9 の一端側の先端部9aに当接して閉磁路が形成される。このとき、カード10は、平衡ばね14のばね力によって、前述とは逆方向へ平行移動する。この平行移動の際、カード10の支持部10b は、シールド部材5 の包囲部5cに設けられた切欠部5dを通過する。
【0018】
こうして、カード10が平行移動すると、同図(b) に示すように、常閉固定端子3c及び共通固定端子3bに、他方可動接触片13b の両端部がそれぞれ接触するとともに、常開固定端子3a及び共通固定端子3bから、一方可動接触片13a の両端部がそれぞれ開離して、シールド部材5 の接触部5eに接触する。このように、両可動接触片13a,13b が3本の固定端子3a,3b,3cに接離することによって、高周波信号が開閉される。
【0019】
かかる高周波信号開閉装置にあっては、包囲部が内方へ折曲されてなる接触部5eは、局部的に厚くなっているわけではないから、コンデンサ成分となることはなく、アイソレーション等の高周波特性が劣化することはない。
【0020】
また、一方可動接触片13a は、図3に示すように、その一方可動接触片13a の延伸方向に沿って設けられた接触部5eに沿うようにして接触するから、シールド部材5 の包囲部5cとの間の相対的位置関係が多少ばらついても、接触部分の先端側と接触部5e近傍の包囲部5cとの間の隙間が小さくなり、安定した高周波特性を得ることができる。なお、他方可動接触片13b についても、同様の効果を奏することができる。
【0021】
なお、本実施形態では、接触部5eは、可動接触片13a,13b の延伸方向に沿って設けられているが、参考例として、例えば、両可動接触片13a,13b とシールド部材5 の包囲部5cとの間の相対的位置関係がばらつく恐れのないときは、このような構成にしなくてもよい。
【0022】
また、本実施形態は、高周波リレーであるが、高周波用スイッチでも同様の効果を奏することができる。
【0023】
【発明の効果】
請求項1記載の発明は、包囲部が内方へ折曲されてなる接触部は、局部的に厚くなっているわけではないから、コンデンサ成分となることはなく、アイソレーション等の高周波特性が劣化することはない。
【0024】
請求項記載の発明は、上記効果に加えて、可動接触片は、その可動接触片の延伸方向に沿って設けられた接触部に沿うようにして接触するから、シールド部材の包囲部との間の相対的位置関係が多少ばらついても、接触部近傍の包囲部との間の隙間が小さくなり、安定した高周波特性を得ることができる。
