Abstract
Abstract An apparatus for containing electromagnetic interference (EMI). The apparatus includes an enclosure for an EMI producing component. The enclosure has a set of springable tabs extending from a top edge of the enclosure and a set of pins extending from a bottom edge of the enclosure. The pins are placed through a grounding ring and a printed circuit board to align and ground the enclosure. The tabs contact a heatsink disposed over the enclosure.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
An enclosure for an EMI producing component, the enclosure comprising: a first plurality of springable tabs extending from a top edge of the enclosure, wherein a portion of each springable tab of said first plurality of springable tabs extends above said top edge; and a second plurality of springable tabs extending from a bottom edge of the enclosure, wherein each of said springable tabs comprises a base, wherein said bases extend outward from the bottom edge such that said second plurality of springable tabs is offset from said first plurality of springable tabs, wherein a portion of each springable tab of said second plurality of springable tabs extends from the base to below said bottom edge.
Claim 2
Dependent Claim
116 words
An enclosure for an EMI producing component, the enclosure comprising: a first plurality of springable tabs extending from a top edge of the enclosure, wherein a portion of each springable tab of said first plurality of springable tabs extends above said top edge; and a second plurality of springable tabs extending from a bottom edge of the enclosure, wherein each of said springable tabs comprises a base, wherein said bases extend outward from the bottom edge such that said second plurality of springable tabs is offset from said first plurality of springable tabs, wherein a portion of each springable tab of said second plurality of springable tabs extends from the base to below said bottom edge.
Claim 3
Dependent Claim
20 words
The enclosure of claim 1 , wherein said first and second pluralities of springable tabs extend out from said enclosure.
Claim 4
Dependent Claim
36 words
The enclosure of claim 1 , wherein said portion of each springable tab of said first and second pluralities of springable tabs has an end substantially parallel to one of said top edge and bottom edge.
Claim 5
Independent Claim
118 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure, wherein said first plurality of contacts are comprised of substantially flat contact ends, and a second plurality of contacts extending from a bottom edge of said enclosure, wherein said second plurality of contacts are in contact with said grounding ring; and a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts.
Claim 6
Independent Claim
118 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure, wherein said first plurality of contacts are comprised of substantially flat contact ends, and a second plurality of contacts extending from a bottom edge of said enclosure, wherein said second plurality of contacts are in contact with said grounding ring; and a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts.
Claim 7
Dependent Claim
22 words
The apparatus of claim 4 , wherein said enclosure is held in place by said heat sink pushing down on said enclosure.
Claim 8
Dependent Claim
17 words
The apparatus of claim 5 , wherein said heat sink is coupled to said printed circuit board.
Claim 9
Independent Claim
114 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure and a second plurality of contacts extending from a bottom edge of said enclosure, wherein said first plurality of contacts comprise springable tabs, wherein said second plurality of contacts are in contact with said grounding ring; and a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts.
Claim 10
Independent Claim
114 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure and a second plurality of contacts extending from a bottom edge of said enclosure, wherein said first plurality of contacts comprise springable tabs, wherein said second plurality of contacts are in contact with said grounding ring; and a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts.
Claim 11
Independent Claim
134 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure and a second plurality of contacts extending from a bottom edge of said enclosure wherein said second plurality of contacts are in contact with said grounding ring; a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts; and wherein said first plurality of contacts comprise springable tabs, wherein said springable tabs are configured to be resiliently urged against a bottom surface of said heat sink during use.
Claim 12
Independent Claim
134 words
An apparatus for containing EMI, the apparatus comprising: a grounding ring on a top surface of a printed circuit board around an EMI producing component; an enclosure disposed on top of said grounding ring, said enclosure comprising a first plurality of contacts extending from a top edge of said enclosure and a second plurality of contacts extending from a bottom edge of said enclosure wherein said second plurality of contacts are in contact with said grounding ring; a heat sink disposed over said component, wherein a bottom surface of said heat sink is in contact with said component and said first plurality of contacts; and wherein said first plurality of contacts comprise springable tabs, wherein said springable tabs are configured to be resiliently urged against a bottom surface of said heat sink during use.
