Enclosure of electronic device
View Patent ↗An enclosure of an electronic device includes a ventilation plate. The ventilation plate is a grid including a number of crisscrossed connection bars and a number of through holes defined by the connection bars. A tab is formed at each of the connection bars bounding each of the through holes. The tabs are substantially angled from a plane of the grid to elongate a path electromagnetic signals must travel to pass through the ventilation plate. The enclosure with the shields can shield the electronic device from EMI.
1. An enclosure of an electronic device, the enclosure comprising a ventilation plate, wherein the ventilation plate is a grid comprising a plurality of crisscrossed connection bars and a plurality of through holes defined by the connection bars; a tab is formed at each of the connection bars bounding each of the through holes; the tabs are substantially angled from a plane of the grid to elongate a path electromagnetic travels along; wherein each tab is divided by the corresponding connection bar into two parts, one of which extends from a side of the late in a first direction, and the other one of which extends from an opposite side of the plate in a second direction opposite to the first direction.
2. The enclosure of claim 1 , wherein each of the tabs is round shaped with the corresponding connection bar extending through the center thereof.
3. The enclosure claim 1 , wherein every two adjacent tabs bounding each of the through holes are perpendicular to each other, and every two opposite tabs bounding each of the through holes are parallel with each other.
4. An enclosure of an electronic device, the enclosure comprising a plate, wherein the plate defines a plurality of through holes, each of the through holes is bounded by four tabs located on different planes; each tab comprises two parts, the two parts of a tab respectively protrude out from two opposite sides of the plate.
5. The enclosure of claim 4 , wherein each tab is round shaped.
6. The enclosure of claim 4 , wherein every two adjacent tabs bounding each of the through holes are perpendicular to each other, and every two opposite tabs in each of the through holes are parallel with each other.
