Connector shielding devices are described herein. One connector shielding device includes a circuit board having a connector that is connectable with a connector of an additional circuit board. The shielding device further includes a plurality of spring fingers connected to and extending from a first surface of the circuit board or a base support adjacent to the first surface of the circuit board. The plurality of spring fingers provides a perimeter around the connector of the circuit board. Additionally, each spring finger of the plurality of spring fingers is configured to deflect toward the first surface of the circuit board when the connector of the circuit board connects with the connector of the additional circuit board. Further, a Faraday cage is provided by the circuit board, the additional circuit board, and the plurality of spring fingers when the connector and the additional connector are connected.
