Abstract
The invention discloses a high-frequency shell type transformer. The high-frequency shell type transformer comprises a magnetic core, a framework and a winding, wherein the framework is used for fixing the magnetic core; and the winding is wound on the framework. The high-frequency shell type transformer is characterized in that high-temperature resistant glue is dispensed in a clearance formed between the winding and the magnetic core after the winding is wound. By dispensing the high-temperature curing glue in the clearance between the winding and the magnetic core, shake is avoided, so that the high-frequency shell type transformer is more stable in structure, and the high-frequency shell type transformer can also be kept stable without shaking at a high temperature.
Description
Technical field
The present invention relates to a kind of high frequency transformer, belong to electronic technology field.
Background technology
In the high frequency shell type transformer, when winding is around on the skeleton because the tightness degree of winding when twining is inconsistent or umber of turn is different, then winding be wrapped on the skeleton back because of and magnetic core between have certain clearance to produce to rock, stable inadequately.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high frequency shell type transformer, avoids rocking, and structure is more stable.
For solving the problems of the technologies described above, the present invention provides a kind of high frequency shell type transformer, comprises the skeleton of magnetic core, fixed magnetic core and is around in the winding on the skeleton, it is characterized in that, twines the gap location that forms between back and magnetic core at winding and puts resistant to elevated temperatures glue.
Said glue is black glue.
Said glue is for solidifying glue.
Said glue is put the interstitial site at the place, four angles that between winding and magnetic core, forms.
Said skeleton is a bakelite.
The beneficial effect that the present invention reached:
High frequency shell type transformer of the present invention through putting resistant to elevated temperatures curing glue at the gap location of magnetic core and winding, has been avoided rocking, and makes high frequency shell type transformer structure more stable, at high temperature can keep equally stablizing, not having and rock.
Description of drawings
Fig. 1 is a high frequency shell type transformer sketch map of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1; High frequency shell type transformer of the present invention comprises the skeleton 2 of magnetic core 1, fixed magnetic core 1 and is around in the winding 3 on the skeleton 2, after winding 3 twines, at the gap location of winding 3 and magnetic core 1 several somes glue points 4 is set; Put resistant to elevated temperatures black glue on 4 place's points at a glue, solidify glue; Usually solidify the gap location of glue point, make not have between winding and magnetic core through curing glue and rock relatively, make structure more stable at four angles of winding and magnetic core formation.
Skeleton 2 is resistant to elevated temperatures bakelite.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
