US 2014/0153192 A1 · MODULE CAGE WITH INTEGRATED EMI ASPECT

Abstract

A receptacle assembly with improved EMI leakage reduction is described. The assembly includes a base in the form of either a guide frame or a shielding cage that received an electronic module or mating connector therein. A heat sink is provided to dissipate heat generated during operation of the connector or module and the heat sink has a portion that extends into the interior of the receptacle through an opening in the top wall thereof. The heat sink has a peripheral rim that is aligned in opposition to a rim of the top wall of the receptacle. A series of individual contact members are disposed in the top wall and arranged in a pattern extending around the opening to provide a plurality of points of electrical grounding contact between the heat sink and the receptacle.
