Electromagnetic interference shielding gasket
First Claim
1. A gasket for shielding electronic equipment from electromagnetic interference, comprising:
- a body having a first edge, a second edge and at least one opening between said edges;
a channel formed between said at least one opening and said first edge; and
a retainer formed between said at least one opening and said second edge, said retainer comprising retaining clips for coupling said gasket to said electronic equipment, wherein some of said retaining clips have opposing curved portions.

Abstract
The present invention is directed to a gasket for reducing electromagnetic emission from electronic equipment. The gasket is defined by a substantially rectangular body that includes one or more openings through which a portion of a connector, to which the gasket is mounted, may pass. The gasket includes a hook-shaped peripheral edge, a plurality of locating projections, a plurality of retaining clips, and tabs that are formed on opposing sides of the opening(s). The hook-shaped edge, locating projections and retaining clips are adapted to receive and secure a connector to the gasket, and the tabs are provide to make an electrical contact with the connector housing. Additionally, the gasket includes spring fingers for use in mounting the gasket to a bulkhead and for forming an electrical contact with the bulkhead.
