Abstract
The invention concerns a radio frequency screen for electronic devices such as radio telephones which contains a small signal part which is to be screened on a circuit board 5 and a power supply part 15. The radio frequency screen consists of two construction elements, the first 1 of which is an approximately straight plate, metal frame or the like which runs parallel to and is the same size as the circuit board of the small signal part. The second construction element 2 consists of a first divider 3 running parallel with the circuit board between the power supply part and the small signal part, which divider continues from its edge 8 in the vicinity of the circuit board 5 as a channel-shaped second divider 4 which is open towards the circuit board, one edge 9 of which lies essentially in the same plane as the corresponding position 10 of the first divider. The first and the second construction elements 1, 2, are both in one piece which is electrically conductive. The power supply part 15 is placed against the adjacent dividers 3, 13 on the side facing away from the small signal part. <IMAGE>
