Notched gasket for low closure force EMI shielding applications

摘要

A EMI shielding gasket for interposition between a first and a second part of a housing or other enclosure. The gasket is supportable on the first part and extends in a longitudinal direction along a first dimension thereof. The profile includes an elongate bearing portion extending axially from a proximal to a distal end contactable by the second part. The bearing portion has an outboard side extending longitudinally intermediate the proximal and distal ends, and an inboard side extending intermediate the proximal and distal ends. The bearing portion is deformable responsive to a compressive force between the first and second parts into a stressed orientation wherein the bearing portion is deflected towards the inboard side and developing in the outboard side a localized high stress region. A stress relief portion is formed in such region which is effective to decrease the compressive force required to deform the bearing portion.
