Ultrathin high-frequency magnetic core transformer and production process thereof

Abstract

The invention discloses an ultrathin high-frequency magnetic core transformer and a production process of the transformer. The ultrathin high-frequency magnetic core transformer comprises a primary coil and a secondary coil, wherein one side of the primary coil is provided with a notch, a copper sheet is embedded in the notch, and the secondary coil is jointed with the notch. The ultrathin high-frequency magnetic core transformer further comprises two magnetic cores, wherein each magnetic core is in a U-shaped structure, and the two magnetic cores are respectively clamped at the tops of the primary coil and the secondary coil, a thin sheet is arranged at one side of the top of the copper sheet, which is close to the primary coil, and the inner surface of the magnetic coil at the top of the primary coil is in complete contact with the thin sheet. The ultrathin high-frequency magnetic core transformer not only has the isolation shielding effect of the transformer, but also has the filtering and interference signal barraging functions of a filter; since the U-shaped magnetic cores are used, the size is small and the cost is low. The production process of the ultrathin high-frequency magnetic core transformer, provided by the invention, has the following advantage that since coil ends are tinned by using a titanium alloy unleaded tin stove, the coil ends are hardly scattered and a good environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an ultra-thin magnetic core high-frequency transformer and a production process thereof. Background technique [0002] The invention of electronic transformer has a history of more than 140 years, and it has developed with the rapid development of electronic technology, and it has also been accompanied by a series of product upgrades. However, in recent decades, due to the popularity and demand growth of high-frequency electronic products such as home appliances, office automation, car navigation systems, safety detection systems, and communications, electronic appliances with high frequency, low loss, small size, and low price As the best-selling product in the market, the demand for thin and high-frequency electronic transformers is increasing accordingly. Therefore, when downstream products put forward higher and newer requirements for components, the living space of tra...

Problems solved by technology

[0003] Due to the characteristics of low price and convenient manufacture, E-type and UI-type plug-in transformers are widely used, but the products with this structure are large in size and heavy in weight, which brings difficulties to the miniaturization of electronic machines.

In the 1960s, C-type and ring-type winding iron core transformers were born, and were soon widely used in various electronic complete machines. However, C-type transformers are noisy, the core processing technology is more complicated, and the quality consistency is poor.

However, due to its large size and high cost, the R-type transformer seriously inhibits the miniaturization production of electronic complete machines.
