Patent ID: 7772505

Claim:
A shielding apparatus for use in providing electromagnetic interference (EMI) shielding for one or more electrical components on a substrate, the shielding apparatus comprising: a first wall having laterally spaced-apart detent protrusions; a second wall having an edge portion disposed relative to the first wall such that an interface between the edge portion of the second wall and the first wall is substantially sealed against the ingress and/or egress of electromagnetic interference through the interface; the edge portion of the second wall engaged generally between and laterally confined by the laterally spaced-apart detent protrusions of the first wall, such that the laterally spaced-apart detent protrusions help inhibit movement of the second wall relative to the first wall, thereby helping retain the interface between the edge portion of the second wall and the first wall substantially sealed against the ingress and/or egress of electromagnetic interference through the interface; wherein the laterally spaced-apart detent protrusions cooperatively define a saddle in which the edge portion of the second wall is engagably received.
