Double-shielded housing for RF circuitry
First Claim
1. An electronic apparatus comprising a housing, said housing being an integrally cast housing and being of an electrically conductive material, said housing having outer walls including a base wall and side walls and further having at least one partition wall, said outer walls together defining an inner space of said housing, an electronic circuit board, said circuit board being removably fastened within said inner space and including at least two electronic circuits located at different sections of said circuit board, said circuit board further being provided with at least one aperture separting said sections from each other, at least one partition wall extending from one of said outer walls into said inner space through said aperture, so as to subtantially divide said inner space into two individual compartments each containing one of said sections of said circuit board, and a first shielding component of an electrically conductive material, said first shielding component being arranged in electrical contact with said housing, so as to substantially close only one of said individual compartments in relation to the other compartment an in relation to the environment, and further provide a shielding of one electronic circuit when the substantially closed compartment in relation to the other electronic circuit and in relation to the environment.

Abstract
An electronic apparatus comprises a housing having walls of an electrically conductive material and together defining an inner space. The walls of the housing comprise outer walls, and partition walls extending from one of the walls of the housing into the inner space of the housing dividing the inner space into different compartments. The apparatus further comprises an electronic circuit board having electronic components mounted thereon and is provided with apertures through which the partition walls extend. In order to shield the electronic circuits of the individual compartments in relation to each other a first shielding component is provided. In order to further shield the circuits of the individual compartments in relation to the environment and vice versa and still further short-circuit any electromagnetic field radiated from the edges of the partition walls and the first shielding component, a further or second shielding component is provided, shielding the individual compartments and the electronic circuits contained within the individual compartments from each other. The outer walls of the housing further shield the electronic circuits of the apparatus from the environment or the surroundings.
