Abstract
Flat printed substrate welded type power transformer, it is characterized in that: by elementary skeleton (2), secondary framework (3), pin (1), primary coil (4), secondary coil (5), iron core, shell and epoxy resin are formed, the good coil of coiling the primary and secondary skeleton having welded pin is positioned over correspondence position epoxy resin encapsulated in shell after inserting iron core helps closure means.Primary coil divides two parts flat around on elementary two skeletons, and is welded on pin, and secondary coil is flat around on secondary framework by coiling order, and is welded on pin, is inserted by iron core in skeleton, finally puts into shell, use epoxy resin encapsulated.By adopting EI type silicon steel sheet, the mode of elementary two coils and a secondary coil increases primary magnetic circuit area, reduces transformer height, completes the power output of regulation.
Description
Technical field
The utility model relates to a kind of power transformer, particularly about one flat printed substrate welded type power transformer, belongs to power electronic equipment technical field.
Background technology
Along with the renewal day by day of electronic product, higher to the requirement of transformer, need to research and develop more compact structure, the transformer that efficiency of transmission is higher, and most products application mode is single in the market, setting height(from bottom) is higher, limits the scope of application of product.
The present invention is mainly in order to solve the problem.
Utility model content
The purpose of this utility model is to overcome existing methodical deficiency in discussion and provides a kind of performance, the power transformer that structure is all good, and it is little that it has setting height(from bottom), and efficiency of transmission is high, the diversified advantage of application mode.Flat printed substrate welded type power transformer, it is characterized in that: by elementary skeleton 2, secondary framework 3, pin 1, primary coil 4, secondary coil 5, iron core, shell and epoxy resin are formed, the good coil of coiling the primary and secondary skeleton having welded pin is positioned over correspondence position epoxy resin encapsulated in shell after inserting iron core helps closure means.Primary coil divides two parts flat around on elementary two skeletons, and is welded on pin, and secondary coil is flat around on secondary framework by coiling order, and be welded on pin, by shown in Fig. 5, iron core is inserted in skeleton, finally put into shell Fig. 2, use epoxy resin encapsulated.By adopting EI type silicon steel sheet, the mode of elementary two coils and a secondary coil increases primary magnetic circuit area, reduces transformer height, completes the power output of regulation.

Technical problem of the present utility model can solve by taking following measure:
Illustrate below in conjunction with accompanying drawing:
The utility model adopts the mode of two armature windings, utilizes the design feature of EI shaped iron core, and realizes the multiple connected mode of input voltage, and transformer whole appearance height is shorter, compact conformation.Skeleton portion is divided in Fig. 1 by two elementary skeletons 2, a secondary framework 3 forms, the through hole that each elementary skeleton both sides end face is respectively fixed for pin with three, the through hole that each secondary framework both sides end face is respectively fixed for pin with three, according to coiling parameter coiling, as Fig. 3.Shell adopts PBT fire-resistant engineering plastics, and angle, four, bottom surface respectively has one for installing the fixing hole that screw is fixed.During dowel core, be elementary skeleton according to left, center, right, secondary framework, the order arrangement of elementary skeleton.Iron core burr direction is consistent.Component drawings after dowel as shown in Figure 5.Static to transformer, after dynamic characteristic carries out initial survey, put in the enclosure according to pin position order, finally use epoxy resin encapsulated.
The beneficial effects of the utility model are:
Do equal-wattage to export, adopt this winding method, reduce transformer whole height, more adapt to the requirement of present electronic market to electronic product, 110V and 220V two kinds of conventional input voltages can be taken into account simultaneously, the requirement of different client can be met greatly.
Embodiment
As an example of the present utility model.Be summarized as follows primary coil to be wound on two elementary skeletons, thus ensure that equal-wattage exports the whole height reducing transformer.
