Abstract
Abstract @ An RF, EMI shielding assembly is disclosed having the capability of capacitively coupling the shielding to system ground so that there will be no ground currents flowing and shocks and arcing will be substantially eliminated. The assembly has a pair of metal shells 12, 14 enclosing a standard connector 70 terminating a shielded cable 72 and a capacitor assembly 16 forming a capacitor with the shells. The capacitor assembly 16 includes springs 46, 48 which make engagement with an equipment closure to effect the capacitive coupling assuring like ground potential throughout the thus connected system.
