Abstract

Abstract The present invention relates to a device for shielding and/or cooling an electronic component mounted on a circuit board or the like. According to the invention, the device comprises a metal frame (2) which is mounted on the circuit board so as to surround the electronic component (1), and a metal cooling plate (3) which fits into the frame (2). The frame is provided along those edges thereof which lie distal to the circuit board with resilient contact means (5) which create electric contact between the plate (3) and the frame (2) and press the cooling plate (3) against the component (1) so as to achieve good thermal transmission between component and cooling plate.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 116 words
A device for shielding and/or cooling an electronic component mounted on a circuit board or the like, characterized in that the device includes a metal frame (2) which is mounted on the circuit board so as to surround the electronic component (1), and a metal cooling plate (3) which fits into the frame (2), wherein the frame is provided with resilient contact means (5) along those edges thereof which lie distal to the circuit board, said contact means creating electric contact between the cooling plate (3) and the frame (2) and functioning to press the cooling plate (3) against the component (1) so as to obtain good thermal transmission between the component and the cooling plate.
Claim 2
Dependent Claim 30 words
A device according to Claim 1, characterized in that the cooling plate (1) is provided with cooling fins (8) on that side thereof which lies distal to the component (1).
Claim 3
Dependent Claim 48 words
A device according to Claim 1, characterized in that the contact means (5) are comprised of tongues (6) which have been clipped downwardly to some extent in the edges of the frame (2) and which are folded inwards and extend slightly above the upper edge of said frame.
Claim 4
Dependent Claim 33 words
A device according to Claim 1, characterized in that the outermost parts (7) of the tongues (6) are folded outwards to form cooling plate guides when inserting the cooling plate into the frame.
Claim 5
Dependent Claim 43 words
A device according to Claim 1, characterized in that the frame (2) is provided with connecting legs (4) for fitting the frame into corresponding holes in the circuit board and for connecting the frame to an earthing surface provided in the circuit board.
