Abstract
The invention relates to an apparatus for shielding an electronic circuit situated on a printed circuit board in an electrically conductive housing which has at least one opening and/or bushing, in which a shielding tube extends from the printed circuit board as far as the housing and encompasses the opening and/or the bushing, and a device for length equalization of the shielding tube forms an electrical contact of the shielding tube independently of tolerances between the printed circuit board and the housing.
Claims8
An apparatus for shielding an electronic circuit situated on a printed circuit board in an electrically conductive housing which has at least one opening and/or bushing, characterized in that a shielding tube (8, 8′, 8″) extends from the printed circuit board (1) as far as the housing (2, 2′, 2″, 3) and encompasses the opening and/or the bushing (6), and in that a device (12;
- 13, 14;
- 13′, 14′) for length equalization of the shielding tube (8, 8′, 8″) forms an electrical contact of the shielding tube (8, 8′, 8″) independently of tolerances between the printed circuit board (1) and the housing (2, 2′, 2″, 3).
