この考案は電子機器におけるプリント基板のシールドケース構造に関する。 The present invention relates to a shield case structure for a printed circuit board in an electronic device.
【０００２】[0002]
従来は図３に示すプリント基板のシールドケース構造が提供されていた。 Conventionally, the shield case structure of the printed circuit board shown in FIG. 3 has been provided.
【０００３】 この構造及び組付けについて説明する。This structure and assembly will be described.
【０００４】 角形で箱体をなし１つの開口面11ａを有したアルミ、銅等の金属製の第１のケ ース11に、底面11ｂの各角近傍に夫々１つ孔11ｃを備えた４個の舌片11ｄを突出 して設け、この上にプリント基板12をパターン面を下にして載置し、４個の舌片 11ｄの孔11ｃに合せて設けたプリント基板12の各孔にネジ５を挿通し孔11ｃに螺 合して取付けている。A first case 11 made of a metal such as aluminum or copper having a rectangular box shape and having one opening surface 11a is provided with one hole 11c near each corner of the bottom surface 11b. The tongue pieces 11d are provided in a protruding manner, the printed circuit board 12 is placed thereon with the pattern surface facing downward, and screws are provided in the respective holes of the printed circuit board 12 which are provided in accordance with the holes 11c of the four tongue pieces 11d. 5 is screwed into the insertion hole 11c.
【０００５】 次に、前記第１のケース11と同様の形状をなし、開口面13ａを有したアルミ、 銅等金属製の第２のケース（蓋）13を、第１のケース11に開口面13ａを向けて嵌 め合せると、第２のケース13は第１のケース11の外側に被せた状態になる。Next, a second case (lid) 13 made of a metal such as aluminum or copper, which has the same shape as the first case 11 and has an opening surface 13 a, is attached to the opening surface of the first case 11. The second case 13 is put on the outer side of the first case 11 when fitted with 13a facing.
【０００６】 そこで、第１のケース11の対向する２つの側面11ｅ及び第２のケース13の対向 する２つの側面13ｂの端部に夫々設けた４個の孔11ｆ及び孔13ｃにネジ５を螺合 して、第１のケース11に第１のケース13を固定している。Therefore, the screws 5 are screwed into the four holes 11f and 13c respectively provided at the ends of the two opposite side surfaces 11e of the first case 11 and the opposite two side surfaces 13b of the second case 13. In addition, the first case 13 is fixed to the first case 11.
【０００７】 これにより、第１のケース11に収納されたプリント基板12は、このプリント基 板12取付け用のネジ５によって舌片11ｄにアース接続され、この舌片11ｄを介し て第１のケース11とアース接続される。As a result, the printed circuit board 12 housed in the first case 11 is grounded to the tongue piece 11d by the screw 5 for mounting the printed board 12, and the first case is connected via the tongue piece 11d. 11 and grounded.
【０００８】 また第１のケース11と第２のケース13とは、夫々の側面11ｃ、13ｂを固定して いる４本のネジ５によってアース接続される。Further, the first case 11 and the second case 13 are grounded by the four screws 5 fixing the respective side surfaces 11c and 13b.
【０００９】 したがって、プリント基板12のアースパターン（図示せず）、第１のケース11 及び第２のケース13は電気的に接続されアースされるため、プリント基板12は静 電ジールドされる。Therefore, the ground pattern (not shown) of the printed circuit board 12, the first case 11 and the second case 13 are electrically connected and grounded, so that the printed circuit board 12 is electrostatically shielded.
【００１０】[0010]
しかし、上記した従来のプリント基板のシールドケース構造は、プリント基板 を第１のケースにネジ４本で取付けなければならず、また、第２のケース（蓋） を第１のケースに固定するのに、側面からネジ４本で取付けていたので、組立て 工数が多くなっていた。 However, in the above-mentioned conventional shield case structure for a printed circuit board, the printed circuit board must be attached to the first case with four screws, and the second case (lid) is fixed to the first case. Moreover, since it was attached from the side with four screws, the number of assembly steps was large.
【００１１】 また、プリント基板のパターン面をチェックする際は、総べてのネジをはずさ なければならず手間がかかっていた。Further, when checking the pattern surface of the printed circuit board, all the screws had to be removed, which was troublesome.
【００１２】 この考案は上記した点に鑑みてなされたものであり、その目的とするところは 従来例の欠点を解消し、組立てが容易なプリント基板のシールドケース構造を提 供するところにある。The present invention has been made in view of the above points, and an object thereof is to solve the drawbacks of the conventional example and provide a shield case structure of a printed circuit board which is easy to assemble.
