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.IT IS A MAGNETIC NUCLEO BOX OF THE TYPE FORMED BY TWO SHELLS (16, 16``) WHICH, PROPERLY FACED AND SOLIDARIZED ONE TO THE OTHER, FORMED TOGETHER, FOR THE WINDING OF AT LEAST ONE ELECTRIC WIRE (15), ONE STEP CENTRAL (19), AND PARALLEL TO THIS CENTRAL STEP (19), DISTANCE FROM THIS, SEVERAL SIDE STEPS (20). ACCORDING TO THE INVENTION, THE SHELLS (16, 16 '') THAT PRESENT ON THEIR PLAN OF UNION (P) COMPLEMENTARY LACE MEANS, SUCH LACE MEANS INCLUDE AT LEAST A PROJECT (B1. B2) CANTILEVERED OVER THIS PLANE OF UNION ( P) AND A CAVITY (E1, E2) IN HOLLOW OVER THIS, AND THE SIDE STEPS (20) ARE ESTABLISHED IN FAVOR OF THESE LACE MEANS. APPLICATION, PARTICULARLY IN DIFFERENTIAL DETECTION DEVICES.
