Abstract
The utility model discloses a switch transformer which comprises a magnetic core, a framework, adhesive tape wound on the magnetic core and pins, wherein the top ends of the two sides of the frameworkare respectively provided with slots. The switch transformer has strong pressure resistance and fast working radiation.
Description
Technical field
The utility model relates to a kind of transformer, particularly a kind of switch transformer.
Background technology
At present, generally be applied to the switch transformer of U.S. mark electronic fluorescent lamp rectifier, because the requirement for height of electron rectifier is lower, volume requirement is less, it is also comparatively harsh to be stranded this requirement for switch transformer, and the input of existing transformer when making is bigger with output winding electric pressure reduction, and fluorescent lamp has generally reached about 700W at the transient voltage of opening, the transformer of this moment promptly needs stronger withstand voltage properties, and heat radiation timely, and input is largely guaranteed by the level of coverage of lacquer liquid with the winding withstand voltage properties of exporting, and existing switch transformer is difficult for infiltrating coil inside when dipping lacquer, thereby influence level of coverage, and the dipping lacquer time is long.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of switch transformer, and withstand voltage properties is strong, the work rapid heat dissipation.
The utility model technical scheme that adopts of dealing with problems is: a kind of switch transformer, and comprise magnetic core, skeleton, enamelled wire, be wound on adhesive tape, stitch on the magnetic core, be respectively equipped with fluting on the top of described skeleton both sides.
Enamelled wire is wound in the winding slot of skeleton in the utility model, enamelled wire after line system is finished and stitch scolding tin, in the skeleton of then magnetic core being packed into, and the magnetic core outer ring around on adhesive tape, carry out dipping lacquer again.
The beneficial effects of the utility model are: the top in the skeleton both sides is respectively equipped with fluting, and lacquer liquid can infiltrate coil inside fast along notch during dipping lacquer, has enlarged the coverage rate of lacquer liquid, and has reduced the time of dipping lacquer, has improved operating efficiency; The fluting of these both sides also can be when transformer be worked distribute heat timely fast, the integral body that reduces transformer heats up.
