ABSTRACT:
This invention relates to an EMI and EMP shield configured to arrest electromagnetic contamination of sensitive electrical and microprocessor equipment. Particularly, the present invention enables a positive dynamic seal for moving parts and joints by means of resilient and self-adjusting conductive contacts. The contacts provide electrical bonding, between otherwise separate and electromagnetically leaky joints, to arrest EMI and EMP contamination.
