Abstract
Abstract An RF screened housing (1;13) according to the invention contains a screening plate (2;15) and having at least two mutually opposite side walls (3;16), which project from said screening plate (2;15) and are designed to engage behind rims of a printed circuit board (5;14), which is fitted with the RF screened housing (1;13), as well as elastic means (7;18) which can be pressed against at least one of the main surfaces of the printed circuit board (5;14) in order to clamp them at the rims to the side walls (3;16). In the embodiment of Fig.2, tabs (6) on the edge of the circuit board engage in respective apertures (4) in the side walls. In another embodiment (Fig.4, not shown), to which the second reference numerals in the brackets refer, the side walls have ribs on their inner surface, which engage with the circuit board, and elastic tabs (18a) also press on the upper surface of the board.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
Self-securing RF screened housing having a screening plate and having at least two mutually opposite side walls, which project from said screening plate and are designed to engage behind rims of a printed circuit board, which is fitted with the RF screened housing, and having elastic means which can be pressed against at least one of the main surfaces of the printed circuit board in order to clamp the latter at the rims to the side walls.
Claim 2
Dependent Claim
77 words
Self-securing RF screened housing having a screening plate and having at least two mutually opposite side walls, which project from said screening plate and are designed to engage behind rims of a printed circuit board, which is fitted with the RF screened housing, and having elastic means which can be pressed against at least one of the main surfaces of the printed circuit board in order to clamp the latter at the rims to the side walls.
Claim 3
Dependent Claim
44 words
Self-securing RF screened housing according to Claim 1, wherein the side walls have openings, which are located at a distance from one another in the longitudinal direction of said side walls, for holding tabs which project at the sides from the printed circuit board.
Claim 4
Dependent Claim
21 words
Self-securing RF screened housing according to Claim 2, wherein the elastic means are designed as lugs which project into the openings.
Claim 5
Dependent Claim
19 words
Self-securing RF screened housing according to Claim 3, wherein the lugs are bent outwards relative to the side wall.
Claim 6
Dependent Claim
26 words
Self-securing RF screened housing according to one of Claims 1 to 4, wherein the side walls are bent outwards in the region of their free rim.
Claim 7
Dependent Claim
45 words
Self-securing RF screened housing according to Claim 1, wherein the side walls have wall regions which are at a distance from one another in the longitudinal direction of the printed circuit board and run inwards, for engaging behind the rims of said printed circuit board.
Claim 8
Dependent Claim
22 words
Self-securing RF screened housing according to Claim 6, wherein the wall regions are formed by impressions in places in the side walls.
Claim 9
Dependent Claim
23 words
Self-securing RF screened housing according to Claim 6, wherein the wall regions are formed by cutting and bending the side walls in places.
Claim 10
Dependent Claim
40 words
Self-securing RF screened housing according to Claim 1 or one of Claims 6 to 8, wherein the printed circuit board can be pressed by the elastic means away from the screening plate and against those wall regions which run inwards.
Claim 11
Dependent Claim
30 words
Self-securing RF screened housing according to Claim 9, wherein the elastic means are formed by lugs which are composed of parts of the screening plate and/or of the side walls.
Claim 12
Dependent Claim
110 words
Self-securing RF screened housing according to Claim 1 or one of Claims 6 to 10, wherein the screening plate has further side walls in the region between the said side walls, on the free edges of which further side walls there are further elastic means for pressing the printed circuit board away from the screening plate. 1 2. Self-securing RF screened housing according to one of Claims 1 to 11, wherein the entire RF screened housing is formed from a single metal sheet. 1 3. Self-securing RF screened housing substantially as hereinbefore described with reference to Figures 1 to 3, 4 and 5 or 6 and 7 of the drawings.
