Wall housing for communications exchange - has earth plate coupled to earth potential conductor paths of printed circuit board and attached modules

摘要

The wall housing has a wall-mounted base (1) with an attached earth plate (2), which is mechanically and electrically coupled to the current supply device (3). The earth plate (2) has contact projections (4) for electrically contacting the earth potential conductor paths of the printed circuit board (5) supported by the earth plate (2) and contact tongues (6) for contacting the earth potential conductor paths of the circuit modules (7) fitted to the circuit board (5). ADVANTAGE - Provides Faraday cage for HF communications appts.
