Through the movable design of the upper baffle plate, the high-frequency transformer provided by the invention is convenient to wind, simple in structure and good in performance.
Description
Technical field
The present invention relates to field transformer, particularly relate to a kind of high frequency transformer.
Background technology
High frequency transformer is as the topmost part of Switching Power Supply, is the vitals carrying out energy storage and transmission.Along with the development of power electronic technology, Switching Power Supply relies on the feature of its high frequency to be widely used in various electronics, electric equipment, among stored-program control exchange, communication, electric power checkout equipment power supply and control appliance power supply, along with the development of power technology, the miniaturization of power-supply system, high frequency and high-power have become an eternal research direction and development trend, current high frequency transformer volume is large, cost is high, and skeleton is all one-body molded, the height due to skeleton is low causes coiling inconvenient.
Summary of the invention
Technical problem to be solved by this invention is: provide the high frequency transformer that a kind of structure is simple, coiling convenient, performance is good.
For reaching above-mentioned technical purpose, the technical solution used in the present invention is:
A kind of high frequency transformer, comprise skeleton, magnetic core, winding, stitch, insulation spacer, it is characterized in that: described skeleton comprises overhead gage, lower baffle plate and bone core, described lower baffle plate and bone core are formed in one, described lower baffle plate and bone core are provided with coaxial line and with the cylindricality through hole of diameter, described bone core is cylindrical body, the thin slice of cylindricality through hole is provided with centered by described overhead gage, described bone core is through the cylindricality through hole of overhead gage, described overhead gage is movable, described overhead gage, lower baffle plate, bone core composition skeleton, described winding is wrapped on bone core, described stitch is fixedly connected with lower baffle plate, described insulation spacer is located at above lower baffle plate, below winding, described magnetic core is fixedly connected with 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 stitch is provided with 4, and is located at the position at 4 angles of lower baffle plate respectively.
Further, the height of described bone core is the height sum of the cylindricality through hole of insulation spacer thickness, winding thickness and overhead gage.
Further, described magnetic core outer surface is also provided with insulating tape.
Adopt such scheme, beneficial effect of the present invention is: described lower baffle plate and bone core are formed in one, described lower baffle plate and bone core are provided with coaxial line and with the cylindricality through hole of diameter, described bone core is cylindrical body, the thin slice of cylindricality through hole is provided with centered by described overhead gage, described bone core is through the cylindricality through hole of overhead gage, and described overhead gage is movable.This project organization is simple, and winding does not have the constraint of overhead gage in winding process, thus more convenient coiling, additionally by the insulation spacer choosing suitably height, coiling can also extrude compacter by movable overhead gage, ensure that the performance of high frequency transformer.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details:
As shown in Figure 1 and Figure 4, a kind of high frequency transformer, comprise skeleton 10, magnetic core 2, winding 3, stitch 4, insulation spacer 5, it is characterized in that: described skeleton 10 comprises overhead gage 11, lower baffle plate 12 and bone core 13, described lower baffle plate 12 and bone core 13 are formed in one, described lower baffle plate 12 and bone core 13 are provided with coaxial line and with the cylindricality through hole of diameter, described bone core 13 is cylindrical body, the thin slice of cylindricality through hole is provided with centered by described overhead gage 11, described bone core 13 is through the cylindricality through hole of overhead gage 11, described overhead gage 11 is movable, described overhead gage 11, lower baffle plate 12, bone core 13 forms skeleton 10, described winding 3 is wrapped on bone core 13, described stitch 4 is fixedly connected with lower baffle plate 12, described insulation spacer 5 is located at above lower baffle plate 12, below winding 3, described magnetic core 2 is fixedly connected with skeleton 10.
As shown in figures 1-4, described overhead gage 11 upper surface, lower baffle plate 12 lower surface are respectively equipped with magnetic core limit rib 14 in the both sides being positioned at magnetic core 2.Described stitch 4 is provided with 4, and is located at the position at 4 angles of lower baffle plate 12 respectively.The height of described bone core 13 is the height sum of the cylindricality through hole of insulation spacer 5 thickness, winding 3 thickness and overhead gage 11.Described magnetic core 2 outer surface is also provided with insulating tape 6.
Structure of the present invention is simple, because overhead gage 11 and bone core 13 can separate, this makes the constraint not having overhead gage 11 at winding 3 in winding process, thus more convenient coiling, additionally by the coiling number of plies of the thickness of overhead gage 11, the height of bone core 13 and required winding 3, choose the insulation spacer 5 of suitably height, like this, coiling can extrude compacter by movable overhead gage 11, ensure that the performance of high frequency transformer.
The present invention is not limited to above-mentioned concrete execution mode, and for the person of ordinary skill of the art from above-mentioned design, without performing creative labour, done all conversion, all drop within protection scope of the present invention.
