Abstract
The utility model discloses a sinking plate type transformer with a frame body as high as 10mm. The sinking plate type transformer comprises a PCB, a magnetic core and a frame, wherein the frame separates the primary stage from the secondary stage. The magnetic core is a horizontal flat magnetic core, the frame is a flat frame, plug foot structures are arranged on the side faces of the frame, holes for enabling the frame body to sink are formed in the PCB, and the height of the frame body on the PCB is smaller than or equal to 10mm. The sinking plate type transformer with the frame body as high as 10mm is reasonable in structure, small in size and suitable for being applied to electrical power system parts of various LED backlight display technologies.
Description
Technical field
The utility model relates to a kind of transformer.
Background technology
The fast development of power electronic technology effectively drives and has promoted the development of power technology, power supply has become very important basic science and technology and industry up to now, and being widely used in every profession and trade, its development trend is high frequency, efficient, densification, big electric currentization and diversification.Simultaneously, the International standardization day by day of encapsulating structure, overall dimension is to adapt to the requirement in global integration market.Switching mode power supply transformer requires size integral body to dwindle under the constant condition of power, frequency, meets the development trend of miniaturization and the slimming of present element pasted on surface.
The switching mode power supply transformer magnetic element of existing market, its volume is high, owing to being made the demand that technique for coiling and physical size limitations can not satisfy slimming, chip type circuit design.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the heavy board-like transformer of 10mm on the little plate of volume.
Technical solution of the present utility model is:
The heavy board-like transformer of 10mm on a kind of plate, comprise PCB wiring board, magnetic core, elementary, the secondary skeleton of isolation, it is characterized in that: magnetic core adopts horizontal flat magnetic core, skeleton adopts flat skeleton, skeleton adopts the side pin configuration, make skeleton body sinking hole wherein, the height≤10mm of skeleton body on the PCB wiring board the setting of PCB wiring board.
The utility model is rational in infrastructure, volume is little, formed by flat, slim EFD type magnetic core and bobbin assembly, this novel transformer magnetic element is desirable AC-AC conversion transformer, isolated flat winding structure transformer is mainly used in the resonant mode loop of LLC topology, characteristics such as the voltage stress of zero voltage switch, device is low are arranged, be highly suitable in the application of some high-efficiency high-power power supplys, its up to the conversion efficiency more than 90% especially other topological structure be beyond one's reach.Along with market requires popularizing of raising and intelligent television to LED TV family expenses comfortableness, require LED TV panel size increasing, Switching Power Supply power also requires to promote significantly.This kind structure transformer is mainly used in the power-supply system part of the Display Technique backlight of various LED, will be used in a large number based on this, and market prospects are very wide.
