App. No. 11/571,619

Abstract

Claims (8)

1 . Device for shielding components on a printed circuit board in a radio base station, which circuit board comprises a first circuit section and a second circuit section, and a conductive border portion arranged on said circuit board between said first circuit section and said second circuit section, said device comprising a conductive shielding cover attachable over at least said first circuit section, with a wall end of said cover connected to said border portion with an intermediate conductive gasket, wherein said cover comprises a distance element devised to engage with a distance reception area, dimensioned such that engagement between the distance element and the distance reception area leaves a gap between the wall end and the border portion defining a maximum obtainable compression for the intermediate conductive gasket.

2 . The device as recited in claim 1 , wherein said distance reception area is arranged on said circuit board.

3 . The device as recited in claim 1 , wherein said distance reception area is flush with said border portion, and said distance element projects a distance corresponding to said gap, from a plane defined by said wall end.

4 . The device as recited in claim 1 , wherein said distance reception area is arranged on a support member for said circuit board.

5 . The device as recited in, claim 1 , comprising fastening means for attaching the cover to the circuit board, wherein said fastening means extend at least partly through said distance element and said distance reception area.

6 . The device as recited in claim 1 , wherein said gap has a width in the range of 0.1-2 mm.

7 . The device as recited in any of the preceding claim 1 , wherein said cover comprises a plurality of walls defining at least two shielding compartments.

8 . The device as recited in claim 1 , wherein said gasket is formed by a string of a flexible conductive compound disposed on said wall end.
