The invention relates to a metal housing for an electronic device for high frequencies, in particular for an ultra-high frequency channel selector with a removable cover that has one on top of it A thin metal layer or metal foil on the inside with an electrical seal against the edge of the housing holds down.

In a known embodiment of this device is between the metal cover and the Metal layer or metal foil an elastic intermediate layer z. B. arranged from foam plastic, wherein the cover is fastened to the housing by means of screws. The invention aims to provide a device to create in which no screws are necessary and often the elastic intermediate layer is dispensable, so that it can be produced cheaply and conveniently in large series.

According to the invention this is achieved in that the cover in a known manner from a rubber-like elastic material, e.g. B. a suitable plastic, made and with a Housing edge is provided clasping edge, the preferably at least once approximately at right angles bent edge of the metal layer or metal foil between the first two mentioned Edges can be clamped.

The invention is explained in more detail with reference to the drawing, in which an embodiment in one Cross section is shown.

The figure shows in section the bucket-shaped metal housing for an ultra-high frequency channel selector, that is divided into a number of compartments by a number of partitions 3 in the usual way is. The individual parts of the channel selector housed in the housing are for the sake of clarity not shown. The housing 1 has an edge 5 which is bent outwards approximately at right angles and is with a lid 7 made of a rubber-like elastic material, e.g. B. a suitable plastic such as Polyethylene, provided, the edge 9 of which engages around the edge 5 of the housing in a clamping manner. In the illustrated Embodiment, the edge 9 of the lid 7 is approximately twice in the same direction bent at right angles. The edge 9 engages, as can be seen from the figure, under the right angles outwardly bent edge 5 of the housing 1, and the cover 7 is on the housing 1 without any further means attached. Thanks to the elasticity of the cover material, the cover can easily be removed from the housing 1 and reattached to it.

On the inside of the cover 7 is a metal foil 11, ζ. B. a copper foil, which from the cover metal housing for an electronic device,
especially for one
Ultra high frequency channel selector

is held pressed against the edge 5 of the housing 1 with an electrical seal. To this end is the edge of the film 11, as can be seen from the figure, similar to the edge 9 of the lid 7 to bent the edge S of the housing 1, and the outer edge part of the film 11 is between the twice approximately at right angles bent part of the edge 9 and the at right angles bent outwards Edge 5 of the housing 1 clamped.

On both sides of the lines indicated in the drawing by the arrows 13, along which the Partition walls 3 are in contact with the film 11, are preferably on the inside of the cover 7 raised ribs or backs 15 are provided which prevent the contact between the film and the partition walls 3 promote. Also along the edge 5 of the housing 1 can similar ribs 17 on the Cover 7 may be provided.

Instead of a separate metal foil 11, a conductive metal layer can be placed on the inside of the cover 7 must be attached.
