Abstract

Изобретение относитс к радиоэлектронике, в частности к конструированию герметичных корпусов дл радиоэлектронных блоков. Цель изобретени - повышение надежности герметизации достигаетс тем, что герметичный корпус содержит кожух 1 с пр моугольным установочным пазом 2 по его периметру, крышку 3 , представл ющую собой тонкую, упругую, выпукло-вогнутую пластину, обращенную своей выпуклостью 4 внутрь кожуха 1, и герметизирующий элемент 5, например сварочный шов. По мере увеличени избыточного давлени загерметизированного корпуса силы трени между ребром крышки и стенками корпуса, вызванные распором крышки, увеличиваютс и превышают силы, стрем щиес сместить крышку отностительно корпуса. При этом герметизирующий шов практически разгружен от напр жени среза. Скольз ща посадка наружной поверхности ребра крышки позвол ет производить монтаж и демонтаж крышки в установочный паз кожуха и производить герметизацию стыка кожух-крышка как капилл рной пайкой, так и сваркой. 3 з.п. ф-лы, 2 ил.The invention relates to electronics, in particular to the design of sealed enclosures for electronic units. The purpose of the invention is to improve the reliability of sealing by the fact that the hermetic body contains a casing 1 with a rectangular installation groove 2 along its perimeter, a cover 3, which is a thin, elastic, convex-concave plate, facing its convexity 4 inside the casing 1, and sealing element 5, for example welding seam. As the overpressure of the sealed body increases, the friction force between the edge of the cover and the walls of the body, caused by the expansion of the cover, increases and exceeds the forces that tend to displace the cover relative to the body. At the same time, the sealing seam is practically unloaded from the shear stress. Sliding the outer surface of the rib of the lid allows mounting and dismounting the lid into the installation groove of the casing and sealing the junction between the casing and the lid both by capillary soldering and welding. 3 hp f-ly, 2 ill.

Claims

SUMMARY OF THE INVENTION and the mounting edges of the cover are made in the form of two-sided ribs with a common end surface 30, and the cover is installed with the possibility of interaction of the common end surface of the two-sided ribs the length of the lid with the shelves perpendicular to the bottom of the casing of the rectangle35 of the coal installation groove of the casing and is oriented by its bulge to the inside of the casing.

2 _O Case pop. 1, on the basis of 4Q. The fact is that the casing on its open side, the lid plate, are rectangular in shape, with the plate being no more than 1/5 of its width and the generatrix of its convex surface is oriented along its length.

3. Case pop. 1, distinguished by the fact that the casing from its open side, the cover plate are in the form of a circle, and the thickness of the

50 tons, not more than 1/5 of the radius of the circle of the plate, and the generatrix of its convex surface is oriented along the radius of the circle of the plate.

4. The housing according to paragraphs. 1-3, about l and _55, characterized in that the sealed inseparable connection is made welded.
