In order to avoid influencing electrical devices or even just one circuit part τοη outside, these housing parts, which are usually used for electrical insulation, are surrounded since the housing for the individual parts normally consists of individual parts and must have the best possible electrical contact with one another. Especially in high-frequency technology and all the more in the cured wave areas, it is of particular importance to eliminate disruptive high-frequency currents, triggered by an ossillator, which is generally done by shielding plates or epeaiell special, closed shielding housings.

Ss is known to have a housing cover that is bent over at the edges outside, e.g. by bidding oddgl., with additional

Correspondingly, the transition has been made to completely solder the connecting parts of the housing, i.e. the cap with its cover, over the circumference, which disadvantageously makes the accessibility of the electrical parts built into the housing practically impossible Provide screws, whereby the deodorant and housing can be firmly connected and in this way several electrical contacts are made via the screw connections. Even if opening of the housing is never possible, the hontag is cumbersome and expensive to manufacture, and the electrical contact is simply not always sufficient unless special effort is made to assemble the individual parts that are joined together.
