Abstract
Abstract A conductive insert for protecting an externally mounted microelectronic device is disclosed. The conductive insert is designed to prevent ESD (Electrostatic Discharge) or RFI (Radio Frequency Interference) destruction or inoperability of the microelectronic device. The conductive insert includes a first exterior surface and a second interior surface. The second interior surface has a conductor material applied thereon for providing ESD or RFI protection to the externally mounted electronic device. To protect the externally mounted microelectronic device, the conductive insert mounts within a mounting plate for covering the externally mounted electronic device. Instead of having a conductive material applied to the interior surface, the conductive insert may be manufactured from a conductive material initially. Additionally, electrically conductive finger springs can be formed in the conductive insert to provide electrical connection between the mounting plate and the microelectronic device or conductive product case.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A structure for providing ESD and RFI protection to an externally mounted electronic device on a computer system, comprising: a mounting plate for covering said externally mounted electronic device, wherein said device is a keyswitch for use in said computer system; and a conductive insert including conductive spring fingers, mounted within said mounting plate, having a first exterior surface and a second interior surface, said second interior surface having a conductive material applied thereto for providing said ESD and RFI protection, said conductive spring fingers extending from said first exterior surface so as to bias said conductive insert against said mounting plate and toward said keyswitch device; wherein said electronic device mounts to a conductive surface, thereby forming a conductive enclosure with said conductive insert and said conductive surface.
Claim 2
Dependent Claim
129 words
A structure for providing ESD and RFI protection to an externally mounted electronic device on a computer system, comprising: a mounting plate for covering said externally mounted electronic device, wherein said device is a keyswitch for use in said computer system; and a conductive insert including conductive spring fingers, mounted within said mounting plate, having a first exterior surface and a second interior surface, said second interior surface having a conductive material applied thereto for providing said ESD and RFI protection, said conductive spring fingers extending from said first exterior surface so as to bias said conductive insert against said mounting plate and toward said keyswitch device; wherein said electronic device mounts to a conductive surface, thereby forming a conductive enclosure with said conductive insert and said conductive surface.
Claim 3
Dependent Claim
110 words
A computer system having a structure for providing ESD and RFI protection to an externally mounted computer system keyswitch electronic device comprising: a conductive system enclosure having an exterior surface; a mounting plate for covering said externally mounted electronic device; and a conductive insert including conductive spring fingers, mounted within said mounting plate and to said exterior surface thereby forming a protective conductive device enclosure for providing said ESD and RFI protection to said externally mounted electronic device, said conductive insert having an outer flange which is generally parallel to a plane defined by said electronic device, said flange further being larger than an outside perimeter of said mounting plate.
Claim 4
Dependent Claim
110 words
A computer system having a structure for providing ESD and RFI protection to an externally mounted computer system keyswitch electronic device comprising: a conductive system enclosure having an exterior surface; a mounting plate for covering said externally mounted electronic device; and a conductive insert including conductive spring fingers, mounted within said mounting plate and to said exterior surface thereby forming a protective conductive device enclosure for providing said ESD and RFI protection to said externally mounted electronic device, said conductive insert having an outer flange which is generally parallel to a plane defined by said electronic device, said flange further being larger than an outside perimeter of said mounting plate.
Claim 5
Dependent Claim
