Abstract
Abstract 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A screening device for an electromagnetically screened metal housing, comprising: a base plate extending along a first plane and having a side edge; and at least one shaped strip formed as a separate part with respect to the base plate, the at least one shaped strip being joined to the side edge of the base plate, the at least one shaped strip including: a strip-shaped contact limb arranged to project away from the front face of the base plate, and a strip-shaped bearing limb joined to the base plate and arranged at at least one of the at least one shaped strip; wherein the base plate includes at least one lateral recessed portion and has outer edges, the at least one shaped strip being inserted into the at least one lateral recessed portion so that the at least one shaped strip is flush with and parallel to the outer edges of the base plate.
Claim 2
Dependent Claim
154 words
A screening device for an electromagnetically screened metal housing, comprising: a base plate extending along a first plane and having a side edge; and at least one shaped strip formed as a separate part with respect to the base plate, the at least one shaped strip being joined to the side edge of the base plate, the at least one shaped strip including: a strip-shaped contact limb arranged to project away from the front face of the base plate, and a strip-shaped bearing limb joined to the base plate and arranged at at least one of the at least one shaped strip; wherein the base plate includes at least one lateral recessed portion and has outer edges, the at least one shaped strip being inserted into the at least one lateral recessed portion so that the at least one shaped strip is flush with and parallel to the outer edges of the base plate.
Claim 3
Dependent Claim
130 words
A screening device for an electromagnetically screened metal housing, comprising: a base plate extending along a first plane and having a side edge; and at least one shaped strip formed as a separate part with respect to the base plate, the at least one shaped strip being joined to the side edge of the base plate, the at least one shaped strip including: a strip-shaped contact limb arranged to project away from the front face of the base plate, and a strip-shaped bearing limb joined to the base plate and arranged at at least one of the at least one shaped strip; a spring element plugging onto the strip-shaped contact limb of the at least one shaped strip and resiliently spreading out sideways from the at least one shaped strip.
