Abstract

L'invenzione fornisce un monitor a tubo a raggi catodici di tipo piatto che elimina in modo efficace una perturbazione di disturbo di un circuito stabilizzatore a commutazione verso un visualizzatore a tubo a raggi catodici. Il monitor a tubo a raggi catodici piatto ha una costruzione in cui una sorgente di alimentazione comprendente uno stabilizzatore a commutazione ed un tubo a raggi catodici piatto (4; 11; 22) sono incorporati in una relazione mutuamente stabile. Un trasformatore di una sorgente di alimentazione a commutazione (1; 17; 27) ed una bobina di deflessione orizzontale (12; 24) sono disposti l'uno rispetto all'altro in modo da minimizzare l'interferenza mutua tra flussi magnetici esterni (7) del primo e flussi magnetici esterni (8) dell'ultimo. In particolare, il trasformatore dell'alimentatore a commutazione (1; 17; 27) è disposto in una posizione spostata e parallela da una linea di centro della bobina di deflessione orizzontale (12; 24) ed in una collocazione in cui una linea retta che si estende lungo il piano di un traferro del nucleo (9) è diretta verso il centro (15) di deflessione. In caso alternativo, il trasformatore dell'alimentatore a commutazione (1; 17; 27) può essere disposto in una posizione sulla linea di centro della bobina di deflessione orizzontale (14; 24) ed in una collocazione in cui il traferro del nucleo (9) si estende per perpendicolarmente alla linea di centro.FIG. 2.The invention provides a cathode ray tube monitor of the flat type which effectively eliminates a disturbance disturbance of a switching stabilizer circuit towards a cathode ray tube display. The flat cathode ray tube monitor has a construction in which a power source comprising a switching stabilizer and a flat cathode ray tube (4; 11; 22) are incorporated in a mutually stable relationship. A transformer of a switched power source (1; 17; 27) and a horizontal deflection coil (12; 24) are arranged with respect to each other so as to minimize mutual interference between external magnetic fluxes (7 ) of the former and external magnetic fluxes (8) of the latter. In particular, the transformer of the switching power supply (1; 17; 27) is arranged in a position displaced and parallel by a center line of the horizontal deflection coil (12; 24) and in a location where a straight line which extending along the plane of an air gap of the core (9) it is directed towards the center (15) of deflection. Alternatively, the transformer of the switching power supply (1; 17; 27) can be arranged in a position on the center line of the horizontal deflection coil (14; 24) and in a location where the air gap of the core (9 ) extends perpendicular to the center line. 2.
