Device for filtering one or more electrical wires to be connected to a casing from outside fits in a multilayer printed circuit board with carrier layers and conductor layers with a filter side part of a contact pin fastened on it.

摘要

A contact pin (20) connects a wire to be connected to a casing (13) from outside. A multilayer printed circuit board (1) has carrier layers (4,6) and conductor layers (5) with a filter side part of the contact pin fastened on it. The board's external layer acts as an all-over or crossbarred screening layer (3,7) making electrical contact with the casing. The board connects to contact pins (9,20) in the conductor layer's conductor strips running outwards.
