Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
This utility model provides a kind of embedding Combined flat board transformer, as shown in Figures 1 to 3 (for the ease of signal embedding The internal structure of Combined flat board transformer, shell 1 is not shown in FIG), including shell 1, and at least 2 are set up in parallel Sub-transformator 2 in shell 1, sub-transformator 2 includes magnetic core 21 and the primary coil 22 being wrapped on magnetic core 21 and secondary Coil 23, primary coil 22 passes shell 1 by primary lead-in wire 221, secondary coil 23 is provided with pin terminals 231, primary Insulation diaphragm 24 it is provided with between coil 22 and secondary coil 23.
It should be noted that the sub-transformator of at least two 2 is juxtaposed in shell 1, refer to the sub-transformation of at least two Device 2 is arranged on same plane with juxtaposition as shown in Figure 1, the such as sub-transformator of two shown in Fig. 12 position is set Put, such set-up mode, on the one hand, the surface area of embedding Combined flat board transformer of the present utility model can be increased, carry The radiating efficiency that high embedding Combined flat board transformer of the present utility model is dispelled the heat by surface area, on the other hand, it is also possible to In the case of not increasing the height dimension of embedding Combined flat board transformer of the present utility model, improve and use power.
Additionally, embedding Combined flat board transformer of the present utility model, can apply to the power work of normal shock or flyback In mode, but this utility model is not limited to this, and embedding Combined flat board transformer of the present utility model can be applied equally to In the power work mode of other such as bridge-type, push-pull types etc., those skilled in the art can select different electrical power according to needs Working method, the corresponding annexation adjusted between sub-transformator 2.
It is internal that the sub-transformator of at least two 2 is set up in parallel and is packaged in shell 1, wherein, and the primary coil in sub-transformator 2 22 pass shell 1 by primary lead-in wire 221, are connected with extraneous alternating current power supply, are used for as embedding Combined flat of the present utility model The power supply input of board transformer, the pin terminals 231 that secondary coil 23 is arranged, as embedding Combined flat of the present utility model The outfan of board transformer.
This utility model provides a kind of embedding Combined flat board transformer, and including shell, and at least 2 are set up in parallel Sub-transformator in shell, sub-transformator includes magnetic core and the primary coil being wrapped on magnetic core and secondary coil, primary Coil passes shell by primary lead-in wire, and secondary coil is provided with pin terminals, arranges between primary coil and secondary coil There is insulation diaphragm.In the case of the height dimension not increasing flat-plate transformer, it is set up in parallel at least by portion in the enclosure Two sub-transformators, the effective power improving flat-plate transformer, by least two sub-transformators are set up in parallel, increase The surface area of flat-plate transformer, improves the radiating efficiency of flat-plate transformer, it is achieved the flattening of finished product, applied widely, can Various miniaturized electronics are promoted the use of.
