In addition to these known removal measures, in which a metallic, more or less resilient insert is used to establish direct electrical contact between the deodorant and the box, a shield cover is also known which consists of a relatively stiff pressure plate which is supported by a resilient intermediate layer made of rubber a relatively flexible, flexible shield plate is covered. When the Deokela is put on and screwed on, this flexible, flexible shielding sheet is pressed very evenly and electrically close to the edges of the shielding box, thus achieving good electrical shielding of the inside of the box. This well-known assumption has proven to be particularly beneficial in the case of shielding boxes in which several box compartments lying next to one another, which are only separated by relative 3ChEaI * partition walls, are to be electrically shielded from the environment and also from each other by a common, large-area, removable shielding cover .

The cover 3 can be screwed on tightly to the box 1 by means of a sight 7.
