Patent ID: 8188381

Claim:
A module retention and electromagnetic interference (EMI) cage system, comprising: an array connector mounted on a surface of a circuit board; an EMI cage mounted on the circuit board, the EMI cage comprising a substantially flat, rectangular metal frame having a first side, a second side, a third side opposite the first side, and a fourth side opposite the second side, each of the first, second, third and fourth sides substantially perpendicular to a plane defining the substantially flat shape of the frame, the array connector disposed within a central region bounded by a perimeter defined by the first, second, third and fourth sides, at least one of the sides having a retaining clip portion, at least two of the first, second, third and fourth sides each having one or more mounting legs extending away from the perimeter parallel to the plane and mounted on the surface of the circuit board, and at least two of the first, second, third and fourth sides each having an EMI skirt comprising three or more closely spaced resiliently deflectable EMI-shielding contact fingers; and an opto-electronic transceiver module pluggably coupled to the array connector by a mating connector on the opto-electronic transceiver module, wherein the EMI skirt of the EMI cage forms an EMI seal around a periphery of the opto-electronic transceiver module, and the retaining clip portion of the EMI cage engages a portion of the opto-electronic transceiver module.
