Description
Technical field
The utility model relates to a kind of transformer production technology, particularly relates to a kind of transformer framework combination with new structure.
Background technology
Electronic product, towards light, little, slim development, makes transformer occupied area on circuit boards significantly to reduce, and transformer group install to circuit board after whole height also must significantly reduce.The miniaturization of transformer is mainly by iron core material.But under identical iron core material, transformer height on circuit boards be reduced, the frame design of transformer must be leaned on.
Install to the height after circuit board to reduce transformer group, transformer has following several different modes in design:
The first, adopt horizontal-type skeleton, this is modal a kind of frame design reducing transformer height.Compared with traditional vertical-type skeleton, this skeleton can reduce the height of transformer significantly.
The second, adopt sunk type skeleton, the pin of transformer framework is made bending shape, the part below transformer lead pin is sunk in the middle of the circuit board that hollows out, reduce transformer group install to the whole height after circuit board to reach.The dogleg section of this type of skeleton pin is subject to the restriction of transformer framework bottom thickness, and submergence depth also can be restricted, and cannot increase the degree of depth of sinking significantly.And the degree of depth of sinking also is fixing cannot adjustment.The pin of skeleton has very long draw distance according to the needs of assembling, causes the monnolithic case area of transformer to become large, takies the area of more circuit board.In addition, whole transformer supports by skeleton pin, and the firmness after assembling product is also poor.
Three, flat surface transformer (Planar Transformer) is adopted.Although the height of flat surface transformer is low, its height is also fix and cannot change.Meanwhile, the withstand voltage effect of this transformer is bad, is not suitable for higher power applications.
In addition, safe distance is a most important ring in transformer framework design.Tradition solve safe distance scheme be exactly take to lengthen bobbin Outside Dimensions the mode of PIN movement outward to meet safe distance.Although this practice can meet safe distance requirement, too increase the area that transformer takies circuit board simultaneously.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of transformer framework combination with new structure.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of transformer framework combination with new structure, comprise the framework main and skeleton shell of standing upside down and arranging, described framework main has longitudinal through hole and is arranged on armature winding and the secondary winding at two ends; The Matching installation of two ends up and down of described through hole has upper magnetic core and lower magnetic core, and the magnetic core center pillar of described upper magnetic core and lower magnetic core inserts in described through hole, and the two ends of two magnetic cores are coated on the outside of described framework main by encircling type docking; Described skeleton shell is U-shaped and inside has the accepting groove that a coupling accommodates frame body and two magnetic cores, the groove body bottom of this skeleton shell is sunk in the installing hole of circuit board, and by the elementary brace table on the two side that is arranged on skeleton shell and secondary brace table across support on circuit boards, wherein, skeleton shell carrys out the submergence depth of control flume body by the height of the elementary brace table of control design case and secondary brace table.
Preferably, described elementary brace table is provided with the winding slot corresponding with described armature winding and multiple elementary PIN.
Preferably, the sidewall of the side near secondary brace table on described skeleton shell is provided with the hole slot facilitating cabling, and secondary brace table is provided with the secondary PIN for installing.
Preferably, the bottom of the accepting groove of described skeleton shell is provided with louvre.
Compared with prior art, beneficial effect of the present invention is: described skeleton shell is that core shapes designs selected by transformer, framework main is stood upside down and is placed on skeleton shell to combine, transformer can be made when constancy of volume so adopt the skeleton of this new structure to combine, reduce transformer and circuit board assemble after whole height, thus allow transformer under the condition meeting characteristic, save cost and saved space.In addition, skeleton shell of the present utility model is supported on circuit boards across being supported on transformer by the elementary brace table at two ends and secondary brace table, not only can not increase the floor space of transformer, and the structure supporting transformer is firm, solves the shortcoming that sunk type skeleton adopts pin to support.Use the winding slot on elementary brace table and secondary brace table and PIN to carry out coiling installation in the assembling structure of framework main and skeleton shell, also can increase safe distance, and improve insulation effect.

Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As Fig. 1,2,3, shown in 4 and 5, the transformer framework combination with new structure that the utility model proposes, comprise the framework main 1 and skeleton shell 2 of standing upside down and arranging, framework main has longitudinal through hole 3, the two ends of framework main are armature winding 4 respectively and secondary winding 5, two winding has PIN; The Matching installation of two ends up and down of through hole 3 has upper magnetic core 6 and lower magnetic core 7, and the magnetic core center pillar of upper magnetic core 6 and lower magnetic core 7 inserts in through hole 3, and the two ends of two magnetic cores are coated on the outside of framework main 1 by encircling type docking; Skeleton shell 2 is U-shaped and inside has the accepting groove 8 that a coupling accommodates frame body and two magnetic cores, the groove body bottom of this skeleton shell 2 is sunk in the installing hole of circuit board, and by the elementary brace table 9 on the two side that is arranged on skeleton shell and secondary brace table 10 across support on circuit boards, wherein, skeleton shell carrys out the submergence depth of control flume body by the height of the elementary brace table of control design case 9 and secondary brace table 10.Elementary brace table 9 is provided with the winding slot corresponding with armature winding 4 and multiple elementary PIN 11.The sidewall of the side near secondary brace table 10 on skeleton shell 2 is provided with the hole slot 12 facilitating cabling, and secondary brace table is provided with the secondary PIN 13 for installing.The bottom of the accepting groove of skeleton shell is provided with louvre 14.
