Screening device for electric appliance, has shielding conductive plate with electrically conductive inner layers that is arranged between noise-sensitive unit and line reactor

摘要

The screening device has noise-sensitive units (4a-4d) that arranged partially on a circuit board (11) to shield the noise from a line reactor. A shielding conductive plate (2) provided with electrically conductive inner layers is arranged between the noise-sensitive unit and the line reactor. An insulating layer is arranged between the electrically conductive inner layers. The electrically conductive inner layer is made of copper. The surface of the electrically conductive inner layer is larger than 16cm 2>.
