Abstract

SE TRATA DE UNA CAJA DE NUCLEO MAGNETICO DEL TIPO FORMADO POR DOS COQUILLAS (16, 16'') QUE, DEBIDAMENTE ENFRENTADAS Y SOLIDARIZADAS UNA A LA OTRA, FORMAN CONJUNTAMENTE, PARA EL BOBINADO DE AL MENOS UN HILO ELECTRICO (15), UN PASO CENTRAL (19), Y PARALELAMENTE A ESTE PASO CENTRAL (19), A DISTANCIA DE ESTE, VARIOS PASOS LATERALES (20). SEGUN LA INVENCION, LAS COQUILLAS (16, 16'') QUE PRESENTAN SOBRE SU PLANO DE UNION (P) MEDIOS DE ENCAJE COMPLEMENTARIOS, DICHOS MEDIOS DE ENCAJE COMPRENDEN AL MENOS UN RESALTE (B1. B2) EN VOLADIZO SOBRE ESTE PLANO DE UNION (P) Y UNA CAVIDAD (E1,E2) EN HUECO SOBRE ESTE, Y LOS PASOS LATERALES (20) ESTAN ESTABLECIDOS A FAVOR DE ESTOS MEDIOS DE ENCAJE. APLICACION, PARTICULARMENTE EN LOS DISPOSITIVOS DE DETECCION DIFERENCIAL.
