Problems solved by technology

[0003] In order to meet the safety distance requirements between the primary and secondary coils, the traditional EFD structure with slots in the middle will make the slot width in the middle of the skeleton very large, which will increase the distance between the primary coil and the secondary coil, resulting in a large leakage inductance of the structure; In addition, the structural transformer usually uses insulating tape to isolate and fix the coils, the width of the winding slot is wide, the requirements for wiring are high, the process operation is complicated, and the automatic winding machine cannot be used for winding.

Abstract

The invention provides an ED type combined resonance transformer. The ED type combined resonance transformer comprises a primary coil, a secondary coil, a primary framework and a secondary framework. The primary coil is provided with a wire spool protruding out of the upper surface of the primary framework. The wire spool is provided with two circles of winding grooves. The two opposite sides of the primary framework are provided with pin bases. The primary coil is wound in the two circles of winding grooves. The secondary framework is provided with a wire spool protruding out of the upper surface of the secondary framework, the wire spool is provided with two circles of winding grooves, the secondary coil is wound in the two circles of winding grooves of the wire spool on the secondary framework, the lower surface of the secondary framework is provided with a groove matched with the wire spool on the primary framework in shape, the groove is buckled on the wire spool of the primary framework, the center of the wire spool on the primary framework and the center of the wire spool on the secondary framework are provided with iron core holes, and the iron core holes are internally provided with iron cores. The ED type combined resonance transformer can meet the requirements for high voltage withstanding and long safety distance.

Description

technical field [0001] The invention relates to a transformer, in particular to an ED type combined resonant transformer. Background technique [0002] At present, the resonant transformer used in the LED TV power supply on the market usually uses the structure of the traditional EFD skeleton with a slot in the middle. [0003] In order to meet the safety distance requirements between the primary and secondary coils, the traditional EFD structure with a slot in the middle will make the slot width in the middle of the skeleton very large, which will increase the distance between the primary coil and the secondary coil, resulting in a large leakage inductance of the structure; In addition, the transformer with this structure usually uses insulating tape to isolate and fix the coils, the width of the winding slot is wide, the requirements for wiring are high, the process operation is complicated, and the automatic winding machine cannot be used for winding.
