Cover for a frame for a device mounted above a printed circuit board in an electronic device
View Patent ↗The disclosure describes a cover for a frame for mounting a device above a printed circuit board (PCB) in an electronic device. The cover comprises: a surface to cover a bottom of the display device and to be located on top of a frame section of a frame that is mounted on the PCB and surrounds a surface device on the PCB; a raised region in the surface to allow a part of the surface device to jut above the frame section; and a depressed region in the surface to receive a feature on a bottom of the display device to allow the feature to extend into an interior cavity bounded by the frame section.
1. A cover for mounting a display device above a printed circuit board (PCB) in within a housing of an electronic device, the cover comprising:
a surface to cover a bottom of the display device and to be located on top of a frame section of a frame that is mounted on the PCB and surrounds a surface device on the PCB;
a raised region in the surface to allow a part of the surface device to jut above the frame section; and
a depressed region in the surface to receive a feature on a bottom of the display device to allow the feature to extend into an interior cavity bounded by the frame section.
2. The cover for mounting a display device above a PCB as claimed in claim 1 , wherein:
the cover is comprised of an electrically conductive material to provide a part of an electrical contact for the display device to a ground plane on the PCB.
3. The cover for mounting a display device above a PCB as claimed in claim 2 , wherein the cover and the frame section combine to provide radio frequency (RF) shielding for the surface device.
4. The cover for mounting a display device above a PCB as claimed in claim 1 , further comprising:
an electrically conductive flange extending upwards to contact the bottom of the display device.
5. The cover for mounting a display device above a PCB as claimed in claim 1 , further comprising:
a snap-fit tab providing a friction fit mating with a corresponding snap-region on the frame.
6. The cover for mounting a display device above a PCB as claimed in claim 5 , wherein the snap-region is shaped to receive at least a portion of a side of the snap-fit tab.
7. The cover for mounting a display device above a PCB as claimed in claim 1 , further comprising:
a first post that interacts with a second post on the frame that interacts with the PCB to secure the frame to the PCB.
8. The cover for mounting a display device above a PCB as claimed in claim 1 , wherein the frame section comprises a plurality of bars.
9. The cover for mounting a display device above a PCB as claimed in claim 8 , wherein the plurality of bars are connected to define an oblong cavity surrounding the surface device.
10. The cover for mounting a display device above a PCB as claimed in claim 8 , wherein the plurality of bars do not define a closed perimeter around the surface device.
