ABSTRACT:
A holder for an electromagneticcoil assembly comprised of joined mirror symmetric E core halves has two bracket pieces which are disposed adjacent to joined legs of the E core halves, each bracket having a pair of bores therein for receiving at least one retainer rod. The rod extends through the brackets and an alignment bore or groove in the core halves. In one embodiment of the holder a retainer plate having bores in registry with the bracket bores also receives the retainer rod, with nuts applied to threaded ends of the retainer rod to exert a uniform retaining pressure along opposite faces of the core halves to maintain a substantially constant core air gap and maximize vibration resistance.
