【考案の詳細な説明】
本案は絶縁とシールドを必要とする電気部品に適用する
シールド装置に関するものである。[Detailed Description of the Invention] The present invention relates to a shielding device that is applied to electrical components that require insulation and shielding.
例えば、テレビジョン受像機に用いられる高圧部品のよ
うに放電または感電のおそれがある電気部品をシールド
する必要がある場合、絶縁とシールドの両機能を与える
構造を設けなければならない。For example, if it is necessary to shield electrical components that are susceptible to electrical discharge or electric shock, such as high-voltage components used in television receivers, a structure must be provided that provides both insulation and shielding functions.
本案は、このような要求に適した簡単なシールド装置を
プリント基板を用いて与えるものである。The present invention provides a simple shielding device suitable for such requirements using a printed circuit board.
本案の実施例を以下図面に従って説明する。第１図は本
案の実施例を示す一部断面を持つ平面図であり、第２図
はその正面図である。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially sectional plan view showing an embodiment of the present invention, and FIG. 2 is a front view thereof.
１はテレビジョン受像機のフライバックパルスを倍圧整
流する倍電圧整流装置のような高圧電気部品である。1 is a high-voltage electrical component such as a voltage doubler rectifier that doubles and rectifies the flyback pulse of a television receiver.
この入出力端子１１．１２は放電を起すおそれがある。These input/output terminals 11 and 12 may cause discharge.
この部品１は、また他の部分に対して金属シールド板２
によってシールドされている。This part 1 also has a metal shield plate 2 for other parts.
shielded by.
しかし、端子１１．１２の部分は隣接して金属シールド
板があると、その部分に放電が起りやすく危険なので開
口部３を設けるようにしている。However, if there is a metal shield plate adjacent to the terminals 11 and 12, electrical discharge is likely to occur there, which is dangerous, so openings 3 are provided.
開口部３の縁３１と各端子１１．１２間の距離は放電が
不可能な十分な距離とする。The distance between the edge 31 of the opening 3 and each terminal 11, 12 is a sufficient distance to prevent discharge.
４は銅箔面４２を一方の面に有するプリント基板であり
、その絶縁板４１が開口部３の電気部品１と反対側の面
に蓋をすべく配置される。4 is a printed circuit board having a copper foil surface 42 on one side, and an insulating plate 41 thereof is arranged to cover the surface of the opening 3 on the side opposite to the electric component 1.
このプリント基板２は孔４３と２１に挿入される螺子５
により金属シールド板２に固定される。This printed circuit board 2 has screws 5 inserted into holes 43 and 21.
It is fixed to the metal shield plate 2 by.
このとき螺子５を通じて銅箔面４２と金属シールド板２
間は電気的に結合される。At this time, the screw 5 connects the copper foil surface 42 to the metal shield plate 2.
are electrically coupled.
またプリント基板４の銅箔面４２は絶縁板４１をはさん
で開口部の反対側に、かつそれを覆うように配置される
。Further, the copper foil surface 42 of the printed circuit board 4 is arranged on the opposite side of the opening with the insulating plate 41 in between, and so as to cover it.
結果として、端子１１．１２の部分は放電に対する絶縁
が十分にとられると共にシールド効果をも満足される。As a result, the terminals 11 and 12 are sufficiently insulated against discharge and have a satisfactory shielding effect.
上記実施例においては、放電のおそれがある部分につい
て説明したが、感電のおそれに対しても同様に該当部分
の絶縁とシールドを行なうことができる。In the above embodiment, a portion where there is a risk of electric discharge has been described, but the corresponding portion can be similarly insulated and shielded against the risk of electric shock.
本案は以上のように、プリント基板を利用して構成でき
るので、簡単かつ取扱いやすいシールド装置とすること
が可能である。As described above, since the present invention can be configured using a printed circuit board, it is possible to provide a shield device that is simple and easy to handle.
