US Patent 7285732 Ultra-low height electromagnetic shielding enclosure

The electromagnetic shielding device includes a frame and a lid. The frame includes sidewalls and upstanding male detent elements with outwardly extending detent protrusions. The lid includes a generally planar top with peripheral lip portions. Slots are formed at the intersection of the lid and the peripheral lip portions so that upstanding male detent elements can extend therethrough and detent engage the frame to the lid. Variations of the detent engagement are shown in different embodiments, by which can be achieved a reduced height of the electromagnetic shielding device.
