Abstract

Una bobina de choque o reactancia perfeccionada que tiene una bobina eléctrica devanada, que comprende una cavidad central rectangular y un núcleo de chapas magnéticas estampadas que rodea la bobina eléctrica por cuatro costados y se extiende también en la cavidad central de la bobina, estando constituida la disposición constructiva de dicho núcleo de chapas magnéticas por un bloque apilado de primeras chapas que se extienden a lo largo de tres costados de la bobina eléctrica y un bloque apilado de segundas chapas que se extiende a lo largo del costado restante de la bobina eléctrica , y que forma juntas a tope con los extremos libres de las primeras chapas, comprendiendo las chapas magnéticas de al menos uno de los bloque apilados una parte que se extienden en la cavidad central de la bobina eléctrica y que forma un entrehierro con las chapas magnéticas transversalmente al eje de la bobina eléctrica, caracterizada porque los bloques apilados de chapas están unidos entre sí mediante una unión de acción brusca que está formada por resaltos formados sobre las chapas de uno de los bloques apilados sobre el interior del núcleo en posición adyacente a las juntas a tope y rebajes cooperantes formados en las chapas magnéticas del otro bloque apilado, estando acoplados entre sí dichos resaltos y rebajes y manteniendo los bloques apilados solicitados mecánicamente entre sí.
