High-frequency electromagnetic screening device for drawer housing - is based on contact spring mouldings snap-fitted into correspondingly dimensioned grooves in frame portions

摘要

The contact spring mouldings (4) arranged in the retaining grooves of the drawer housing (1) comprise each a convex middle portion and an end piece bent over and snapped into the groove, which is as long as the end with a dovetail cross-section between upper and lower projections. The bend has a relatively small radius at the transition through an angle of about 150 deg. between the middle portion and the downward inclined straight end. ADVANTAGE - Reliable HF screening is guaranteed at low mfg. cost by easily and quickly fitted contact spring mouldings.
