Electromagnetic interference shield

摘要

An electromagnetic interference (EMI) shield that increases the airflow through the EMI shield while preventing line-of-sight openings through the EMI shield. Two plates are coupled together. Each of the respective plates has a raised component with an aperture therethrough to provide a path through the plate. The raised component is preferably scoop-shaped with the aperture at one end and an opposite end tapering into the respective plate. At least a portion of one of the raised components overlaps at least a portion of the other of the raised components when the plates are coupled together to form a path through the plates, while the plates are coupled together. Line-of-sight openings through the plates, to an electronic device protected by the EMI shield, are at least partially prevented by the raised components.

主权项

1. An apparatus for electromagnetic shielding, the apparatus comprising:
a first plate comprising a first front face and a first back face, and a first raised component on the first front face with an aperture therethrough providing a path through the first plate and a second raised component on the first front face with an aperture therethrough providing a separate path through the first plate; a second plate comprising a second front face and a second back face, and a third raised component on the second front face with an aperture therethrough providing a path through the second plate and a fourth raised component on the second front face with an aperture therethrough providing a separate path the second plate; and the first back face coupled to the second back face, wherein at least a portion of the first raised component overlaps with at least a portion of the third raised component to provide a first path through both plates via the aperture of the first raised component and the aperture of the third raised component, and wherein at least a portion of the second raised component overlaps with at least a portion of the fourth raised component to provide a second path through both plates via the aperture of the second raised component and the aperture of the fourth raised component; wherein the adjoined first and second plates are folded in between the overlapping first and third raised components and the overlapping second and fourth raised components, such that direct line-of-sight is maintained between the first and second raised components on the first plate and direct line-of-sight is at least partially prevented between the third and fourth raised components on the second plate by the folded adjoined first and second plates.
