Abstract

The invention discloses an embedded thin transformer which comprises magnetic cores, a primary winding unit and a secondary winding unit, wherein the secondary winding unit is inserted in the primary winding unit, and the primary winding unit and the secondary winding unit are respectively provided with a winding groove; the primary winding unit is internally provided with an accommodating cavity for accommodating the winding groove of the secondary winding unit, the winding groove is arranged at the upper part of the accommodating cavity; and a vertical hollow passage is formed at the centers of the winding groove and the accommodating cavity; and the magnetic cores are inserted respectively from two sides of the hollow passage so as to form a whole body. By virtue of the reasonable design, the space utilization ratio of the transformer is improved, and the thinning and miniaturization of transformer products can be benefited. The embedded thin transformer disclosed by the invention is simple in structure, low in manufacturing cost and beneficial to the automatic production of products.

Description

A kind of embedded thin type transformer
Technical field
The present invention relates to a kind of transformer, especially a kind of embedded thin type transformer.
Background technology
Along with thin typeization, the miniaturization development of electronic product, the volume requirement of electronic transformer is also more and more littler, more and more thinner.But, for satisfying electronic product Safety Design standard,, need adopt by transformer Teflon sleeve pipe, end control adhesive tape, insulating tape etc. when making to reach the purpose that meets safety standard, and this makes the volume of power transformer product to diminish; On the other hand; No matter be that the transformer lead-out wire increases the Teflon sleeve pipe or increases end control adhesive tape or employing insulating tape; All increased a large amount of labor hours, be unfavorable for the automated production operation of product, the manufacture method of this high density handwork can't satisfy the demand in market.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, provide a kind of space availability ratio high, and embedded thin type transformer simple in structure.
Technical scheme: in order to realize above purpose, embedded thin type transformer of the present invention comprises magnetic core, elementary winding element, secondary winding unit; The secondary winding unit is plugged in the elementary winding element; And at described elementary winding element; The secondary winding unit is respectively equipped with winding slot; Be provided with the containment type cavity of the winding slot that holds the secondary winding unit in the described elementary winding element, winding slot is arranged on this containment type cavity top, and described winding slot and containment type cavity center are the hollow channel of above-below direction; Magnetic core inserts respectively and is integrally formed from the hollow channel both sides.
Described hollow channel is a circular arc.
Described winding slot becomes double-decker.
The edge of the edge of described elementary winding element and secondary winding unit is equipped with pin.
The thickness of described magnetic core is 14.8 ± 0.5mm.
Beneficial effect: a kind of embedded thin type transformer provided by the invention is through reasonably design; Improved the utilance of spatial transformer, help thin typeization, the miniaturization of power transformer product, and the present invention has been simple in structure; Cost of manufacture is low, helps the automated production of product.。
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical view of the present invention;
Wherein: 1. iron core, 2. elementary winding element, 3. secondary winding unit, 4. winding slot, 21. elementary winding element winding slots, 31 secondary winding unit winding slots.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2, a kind of embedded thin type transformer of the present invention comprises that thickness is that 14.8 ± 0.5mm is magnetic core 1, elementary winding element 2, secondary winding unit 3; Secondary winding unit 3 is plugged in the elementary winding element 2; And at described elementary winding element 2; Secondary winding unit 3 is respectively equipped with winding slot 21,31; Be provided with the containment type cavity of the winding slot 31 that holds secondary winding unit 3 in the described elementary winding element 2, winding slot 21 is arranged on this containment type cavity top, and described winding slot 21,31 and containment type cavity center are the circular arc hollow channel 4 of above-below direction; Magnetic core 1 inserts respectively and is integrally formed from hollow channel 4 both sides.
When elementary winding element 2 guarantees the transformer operate as normal with overlapping of secondary winding unit 3; Improved space availability ratio, helped the miniaturization of power transformer product, described elementary winding element 2 is divided into two independent parts with secondary winding unit 3; And 31 one-tenth double-deckers of described winding slot; When making things convenient for winding, winding slot is divided into multilayer, avoided the phase mutual interference between the winding; Be convenient to realize automated production, help reducing cost of labor, the edge of the edge of described elementary winding element 2 and secondary winding unit 3 is equipped with pin, and the thickness of described iron core 1 is 14.8 ± 0.5mm, and described hollow channel 4 is a circular arc.
Implement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
