Abstract
A method and apparatus for adding shielding for electronic circuit packs. The invention includes a circuit pack cage, which has a first pair of parallel longitudinal circuit pack slots for receiving the circuit packs and further has a first longitudinal shield slot disposed between first pair of circuit pack slots for receiving a conductive sheet member. At least one conductive resilient member is disposed in the first shield slot in electrical coupling with a conductive chassis. Upon sliding the conductive sheet member between the pair of circuit packs and into the shield slot, the resilient member flexibly engages the conductive sheet member and electrically couples the conductive sheet member with the conductive chassis.

An apparatus for electromagnetically shielding a pair of electronic circuit packs from one another comprising:
- a conductive sheet member separate and distinct from the circuit packs;
- a circuit pack cage:
- having a first pair of parallel longitudinal circuit pack slots for receiving the pair of circuit packs and for spatially arranging the circuit packs in parallel with one another, wherein the circuit pack slots slideably engage the circuit packs, and
- further having a first longitudinal shield slot separate and distinct from the circuit pack slots and disposed between said first pair of circuit pack slots for receiving the conductive sheet member and for arranging the sheet member between the circuit packs, wherein the shield slot slideably engages the conductive sheet member;
- a conductive chassis mechanically coupled with the circuit pack cage for supporting the cage and the circuit packs;
- and
- at least one independent, separate, autonomous conductive resilient member disposed in the first shield slot and arranged for directly electrically coupling the conductive sheet member with the conductive chassis.
An apparatus for electromagnetically shielding a plurality of electronic circuit packs from one another comprising:
- a plurality of conductive sheet members separate and distinct from the circuit packs;
- a circuit pack cage:
- having a first set of parallel longitudinal circuit pack slots for receiving the circuit packs and for spatially arranging the circuit packs in parallel with one another, and
- further having a first set of parallel longitudinal shield slots separate and distinct from the circuit pack slots and interdigitated with the first set of circuit pack slots for receiving the conductive sheet members and for arranging each conductive sheet member between a respective pair of circuit packs;
- a conductive chassis mechanically coupled with the circuit pack cage for supporting the cage and the circuit packs;
- and
- a first set of autonomous conductive resilient members each disposed in a respective one of the first shield slots and arranged for independently electrically coupling the respective conductive sheet member with the conductive chassis.
A method for shielding a pair of electronic circuit packs from one another comprising the steps of:
