Assembly of shielded connectors and a board having plated holes

An assembly comprising at least one connector (2) and a board (1), said at least one connector (2) being connected to a predetermined side of said board (1) and comprising at least one signal contact member (3) fitted in an electrically conductive blind hole (7) of the board (1) electrically connected to at least one signal layer (4, 5), the connector comprising electrically conductive connector shielding means (61) to shield at least one signal contact member (3) characterized in that said connector shielding means (61) comprises a shielded connector housing enclosing housing enclosing at least one contact member (3), that each said hole (7) is provided with an electrically conductive layer (44) on its inside surface and that the board (1), except in areas where connectors (2, 12, 17, 50) are fitted to the board (1), is provided with a first continuous electrically conductive layer (9) on one side and a second continuous electrically conductive layer (10) disposed in opposed relation to the first electrically conducting layer (9), each of the shielded connector housings being electrically connected to one of said layers (9, 10), in order to substantially prevent electromagnetic radiation generated by any of said signal contact members (3) from propagating to the outside world.
