している。2. Description of the Related Art Conventionally, this type of electromagnetic shielding casing has had a structure as shown in FIG. In FIG. 3, 1 is a lid and 2 is a case part. A microwave circuit board is housed inside the case part 2, and by attaching a lid 1 to the case part 2, power leaking from inside the case part 2 to the outside is cut off.

所を増す等の対策がとられていたが、量産上、工数の点
などから問題であった。Problems to be Solved by the Invention With such an electromagnetic shielding case with a conventional structure, it is difficult to completely cut off power leakage through the gap between the case and the lid. Countermeasures such as increasing the number of parts were taken, but this was a problem in terms of mass production and man-hours.
本発明は、以上の点に鑑みてなされたものであり、簡単
な構成で量産性に適し、しかも優れた電磁シールド効果
が得られる電磁シールド筐体を提供することを目的とす
る。The present invention has been made in view of the above points, and an object of the present invention is to provide an electromagnetic shielding case that has a simple configuration, is suitable for mass production, and can provide an excellent electromagnetic shielding effect.

を挿入したものである。Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to insert a thin metal plate between the case part that houses the microwave circuit board and the lid.
作用 この技術的手段による作用は次のようになる。action The effect of this technical means is as follows.
すなわち、ケース部と蓋との間に隙間があり、この隙間

ケースと蓋との間の隙間が存在しても、その隙間の長さ
が半波長未満とすることによっても同様の作用が得られ
る。That is, there is a gap between the case part and the lid, and if the length of this gap becomes more than half a wavelength, the electromagnetic energy inside the case will leak out of the case due to the effect of the 20-foot antenna. Therefore, by inserting a metal plate between the case and the lid, the structural conditions of the slot antenna can be changed, thereby preventing leakage of electromagnetic energy from the case. Furthermore, by making the shape of the metal plate wavy and providing multiple protrusions and cut-and-raised spring structures,
Even if there is a gap between the case and the lid, the same effect can be obtained by making the length of the gap less than half a wavelength.
実施例
