| 摘要 |
The invention relates to an arrangement for attenuating electromagnetic interference propagating through a connector (11) in an electronic device positioned in a metal housing (1, 2). The inner space of the grounded metal housing (1, 2) is divided into at least three separate, substantially radiation-proof compartments (7, 9, 10) by metal partition walls (4, 6, 8) and/or metal foils (21) provided in a printed circuit board (3). The connector (11) is positioned in the first compartment (9) in the outer wall of the housing, and the electronic circuits which cause interference or are sensitive to it are substantially positioned in the third compartment (10). Each connection wire (13a, 13b, 13c) from the connector passes into the second compartment (7) from the first compartment through a respective first wire hole (18) provided in the grounded metal foil (21) of the printed circuit board (3), and then into the third compartment (10) from the second compartment through a respective second wire hole (19) provided in the grounded metal foil (21) of the printed circuit board (3). |
