Abstract

LA INVENCION SE REFIERE A UN TRANSFORMADOR ULTRASONICO CON UN ELEMENTO DE OSCILACION A MODO DE CAZO QUE SE COLOCA EN UNA CARCASA DE TRANSFORMADOR Y QUE EN SU FONDO SOPORTA UN DISCO PIEZO ELECTRICO. LA TAREA DE LA INVENCION CONSISTE EN SIMPLIFICAR EL CONTACTO ELECTRICO ENTRE LAS LINEAS DE CONEXION Y EL ELEMENTO DE OSCILACION O EL DISCO PIEZO ELECTRICO Y DE ADAPTARLO A UNA FABRICACION AUTOMATICA. LA INVENCION SE COMPONE DE RESORTES DE CONTACTO (3, 4) QUE YA NO SE UNEN POR SOLDADURA A LOS ELEMENTOS CITADOS NI SE CALAFATEAN, SINO QUE SE COLOCAN SOBRE LOS MISMOS SOLO ELASTICAMENTE. LAS MEJORAS SE CONSIGUEN POR MEDIO DE UN CUERPO DE CONTACTO (1) FUNDAMENTALMENTE A MODO DE CILINDRO CON EL QUE SE SELLAN LOS RESORTES DE CONTACTO (3, 4) Y QUE, AL MISMO TIEMPO, PUEDE SERVIR COMO ELEMENTO DE AMORTIZACION.
