Abstract

The invention discloses an asymmetric thin high-frequency switching power supply transformer, which comprises a frame, a magnetic core, pins, an enameled wire and an enhanced insulating wire, wherein the frame comprises a primary outer edge, a secondary outer edge and a winding slot; the primary outer edge and the secondary outer edge are arranged on the two sides of the winding slot; the primary and secondary pins are fixed to the primary and secondary outer edges respectively; the central part of the winding slot is provided with a vertical hollow passage, and two ends of the winding slot are provided with upper and lower baffle plates; the magnetic core is embedded in the frame; and the enameled wire and the enhanced insulating wire are wound in the winding slot and are connected with the primary and secondary pins respectively. The widths of the primary and secondary outer edges of the transformer are asymmetric and the product is thinner and has the height of only 12.2mm and output power of about 100W, so that the transformer can be widely applied to LED television sets and LED displays.

Description

technical field [0001] The invention relates to a transformer, in particular to an asymmetrical thin high-frequency switching power supply transformer applied to ultra-thin LED TV sets and LED displays. Background technique [0002] After years of development, TV sets and monitors have developed from CRT TVs, CRT monitors, LCD liquid crystal TVs, and LCD liquid crystal monitors to current LED TV sets and LED monitors. Using LED technology, it can produce thinner, brighter and clearer display effects than LCD, and has a wide range of application prospects. However, the height and structure of the power transformer inside the existing TV set limit the reduction of the thickness of the LED TV set and the LED display, and become the main components that restrict the development of the LED TV set and the LED display. In order to meet the market demand for thinner TVs and monitors and low energy consumption, a thin high-frequency switching power supply transformer for LED TVs and...
