An electro-magnetic interference (EMI) gasket assembly for attachment to a front plate of a device card, the EMI gasket assembly comprising:
- a fabric-over-foam gasket extending over a width of the front plate;
- and
- a plurality of finger gaskets attachable to the front plate, wherein the finger gaskets are positioned to hold the fabric-over-foam gasket on the front plate and wherein the finger gaskets each include a curved main body with opposite ends, wherein an angled end segment extends under the curved main body from each of the opposite ends, and wherein the end segments are insertable under an edge of the front plate.
A device card comprising:
- a circuit board having a connector edge and an opposite front edge;
- a front plate coupled to front edge of the circuit board, wherein the front plate and circuit board are insertable into a slot on a panel of a chassis;
- a fabric-over-foam gasket extending a width of the front plate;
- and
- a plurality of finger gaskets are attached to the front plate, wherein the finger gaskets are positioned to hold the fabric-over-foam gasket on the front plate, and wherein the finger gaskets each include a curved main body with opposite ends, wherein an angled end segment extends under the curved main body from each of the opposite ends, and wherein the end segments are insertable under an edge of the front plate, and wherein the fabric-over-foam gasket and finger gaskets block gaps between the front plate and the slot.
A computer system comprising:
- a chassis having an internal connector and a panel with a slot;
- a device card including a circuit board, a front plate, an operating component and a connector, the device card insertable in the slot such that the connector is connected to the internal connector;
- and
- a gasket assembly connected to the device card to shield gaps between the slot and the device card, the gasket assembly including:
- a fabric-over-foam gasket extending a width of the front plate;
- and
- a plurality of finger gaskets are attached to the front plate, wherein the finger gaskets each include a curved main body with opposite ends, wherein an angled end segment extends under the curved main body from each of the opposite ends, and wherein the end segments are insertable under an edge of the front plate, and wherein the finger gaskets are positioned to hold the fabric-over-foam gasket on the front plate.
