Utility model content
Technical problem to be solved in the utility model is: provide a kind of easy to process, cost is low, magnetic post not easy fracture, high frequency transformer that performance is good.
For reaching above-mentioned technical purpose, the technical solution adopted in the utility model is:
A kind of high frequency transformer, comprise skeleton, magnetic core, winding, insulation spacer, it is characterized in that: described skeleton comprises overhead gage, lower baffle plate and bone core, described overhead gage, lower baffle plate and bone core are formed in one, described overhead gage, lower baffle plate and bone core are provided with coaxial line and with the cylindricality through hole of diameter, described winding is wrapped on bone core, described insulation spacer is located at above lower baffle plate, below winding, described magnetic core comprises three magnetic posts and two yokes, described magnetic post vertically arranges, yoke is horizontal, magnetic post and yoke form day font magnetic core, described three magnetic posts and the yoke be positioned at above magnetic post are formed in one, another yoke is shaping separately, described magnetic core is closely fixedly connected with skeleton.
Further, the length of described three magnetic posts is identical, and middle magnetic post is cylinder, and described two yoke size and shapes are all identical.
Further, the magnetic column diameter of described centre is less than the diameter of the cylindricality through hole of skeleton.
Further, described overhead gage upper surface, lower baffle plate lower surface are respectively equipped with magnetic core limit rib in the both sides being positioned at magnetic core.
Further, described lower baffle plate is also provided with 4 stitch, and described stitch is located at the position at 4 angles of lower baffle plate.
Further, described magnetic core outer surface is also provided with insulating tape.
Adopt such scheme, the beneficial effects of the utility model are: described magnetic core comprises three magnetic posts and two yokes, described magnetic post vertically arranges, yoke is horizontal, magnetic post and yoke form day font magnetic core, described three magnetic posts and the yoke be positioned at above magnetic post are formed in one, and another yoke is shaping separately.This project organization is simple, and easy to process, save material and cost, magnetic core coordinates closely with skeleton, and improve the performance of high frequency transformer, magnetic core is easy fracture not.
