Abstract
Abstract A contact device includes a plurality of spring fingers on a conductive strip, each of the plurality of spring fingers having a cantilever spring portion, a locking tab, and a lead-in flange. The plurality of cantilever springs provide grounding contact to a removable cover when the plurality of locking tabs clip into a plurality of locking tab slots on the removable cover. Each lead-in flange has a lance-out tab. Every other of the plurality of lanced-out flanges clip into each of a plurality of lanced-out tab slots on the removable cover. Thus, after installation, the locking tab and the lead-in flange on each spring finger of the conductive strip provide for a clip-on, one-way positive-locking, non-snag, grounding contact with the cover of a base enclosure, furnishing an electromagnetic shield of electronic equipment within the base enclosure.
