Patent ID: 7365630

Claim:
A low magnetic leakage high voltage transformer comprising an electrically insulative holder frame, a primary winding bracket mounted in said electrically insulative holder frame at one side, a secondary winding bracket mounted in said electrically insulative holder frame at an opposite side, a plurality of primary windings wound on said primary winding bracket, a plurality of secondary windings wound on said secondary winding bracket, and an FERRITE core set mounted in said primary winding bracket and said secondary winding bracket for producing a magnetic field to induce an electric current going through said primary windings and said secondary windings, said FERRITE core set comprising two U-shaped FERRITE cores inserted into said primary winding bracket and said secondary winding bracket from two opposite sides and abutted against each other in said primary winding bracket and said secondary winding bracket, wherein said electrically insulative holder frame comprises an insertion slot on a top side thereof, and a plurality of baffle flanges downwardly extending from a top wall thereof at two sides of said insertion slot to isolate said FERRITE core set from said primary windings and said secondary windings; said primary winding bracket and said secondary winding bracket each have a partition flange and a mounting slot formed in said partition flange in communication with said insertion slot of said electrically insulative holder frame; said FERRITE core set comprises a straight FERRITE core inserted into said insertion slot of said electrically insulative holder frame and said mounting slots of said primary winding bracket and said secondary winding bracket and stopped between said baffle flanges of said electrically insulative holder frame within the partition flanges of said primary winding bracket and said secondary winding bracket and kept in contact with said U-shaped FERRITE cores.
