Abstract
An electromagnetic coil assembly particularly suited for use in high-acceleration impact devices includes an inner hub having a flat metal and dielectric strip wound thereabout to form a coil, and an outer body mounted about the inner hub against one side of the coil. Inner and outer coil leads are formed by flat 90° bends of the inner and outer ends of the coil strip, such that the coil leads extend axially away from the coil toward one end of the coil assembly. Recesses are formed in the end faces of the inner hub and outer body at this end of the assembly, and the coil leads are folded into these recesses and attached by lug connectors to a pair of electrical conductors that lead out the side of the coil assembly. The coil leads and conductors are secured in the recesses, preferably by potting them in place.
