Abstract

The present invention relates to electromagnetic shielding of components and circuits arranged on a printed wiring board within a housing of an electric apparatus. A housing for an insert card (200) comprises a first and a second rectangular housing part (203, 204) with a number of resilient spaced-apart tongues (214-217) formed as part of the respective first and second housing part. The resilient spaced-apart tongues (214-217) abut corresponding ground-conductors (222a-b) at least partly enclosing components to be electromagnetic shielded on the printed wiring board (205). This forms EM-shielded zones inside the insert card (200).
