Abstract
A block of foam is wrapped with a conductive foil to replace a metal spring used to both support and ground an electrical component in an electronic device. In particular, the foam block wrapped in foil may be used to support a video board in a display device while grounding the EMI shielding on the board and related components. The foil is preferably adhered to the foam block with an adhesive.
Claims22
A device for both supporting a component of an electronic device and providing and electrical pathway from said component, the device comprising:
- a block of foam, said block being square when viewed from above and having top and bottom opposing surfaces;
- and
- a conductive foil providing said electrical pathway disposed on said block,
- wherein an adhesive is located only on said top and bottom surfaces.
A display device comprising:
- an EMI-shielded circuit board;
- a block of foam for supporting said circuit board, said block being square when viewed from above and having top and bottom opposing surfaces;
- and
- a conductive foil disposed on said block for grounding said circuit board,
- wherein an adhesive is located only on said top and bottom surfaces.
A method of both supporting a component of an electronic device and providing and electrical pathway from said component, the method comprising:
- locating an adhesive only on said top and bottom opposing surfaces of a block of foam, said block being square when viewed from above;
- and
- supporting said component with said block on which a conductive foil is disposed providing said electrical pathway.
A method of making a device for both supporting a component of an electronic device and providing and electrical pathway from said component, the method comprising:
- locating an adhesive only on said top and bottom opposing surfaces of a block of foam, said block being square when viewed from above;
- and
- disposing a conductive foil which forms said electrical pathway on said block.
A method of making a display device comprising;
- locating an adhesive only on said top and bottom opposing surfaces of a block of foam, said being square when viewed from above:
- and
- supporting an EMI-shielded circuit board with said block having a conductive foil disposed thereon for grounding said circuit board.
