Abstract
A filtered electrical connection assembly in an electroexplosive device uses a lossy magnetostrictive ferrite element surrounding an electrical conductor. The ferrite element is immersed in a dielectric heat transfer liquid, and an epoxy-based potting compound, used to seal the opening through which electrical wires enter the device, is maintained separate from the ferrite element so that its shrinkage during curing does not compressively load the ferrite element and thereby impair its effectiveness as an RF attenuator. The liquid transfers heat away from the ferrite element, thereby preventing its effectiveness from being degraded by high temperatures, and preventing excessive heat from being conducted toward the pyrotechnic charge, and its initiating bridge, through the electrical conductor.
