Screening device having a low overall height for electromagnetically screened metal housing

In order to be able to ensure interference-free functioning of electric circuits and the like, it is necessary to screen the latter against electromagnetic waves. For this purpose, the housing which surrounds the electric circuit must predominantly comprise metal housing parts. In this case, the screening prevents both penetration of electromagnetic waves and their escape from the housing. It is necessary for this purpose to establish between the metal housing parts continuously electrically conducting connections, in particular via contact spring elements. These connections must be as free from gaps as possible as a function of the level of the electromagnetic frequencies. The present invention relates to a screening device having a base plate and at least one shaped strip which can be joined to a side edge of the base plate. In this case, a shaped strip can be designed as a contact shaped strip or as a spring shaped strip with a plugged-on contact socket connector, and can advantageously be joined respectively to opposite side edges of a base plate. The advantage of the screening device in accordance with the present invention is, in particular, the low height of the shaped strips and, resulting therefrom, the electromagnetic screening, extending virtually ideally in one plane, of the metal housing, in particular in the case of a plurality of screening devices arranged next to one another. With subracks, the screening device in accordance with the present invention can be used, for example, as a rear cover or as a front filler panel for unassigned module locations.
