Description
Technical field
The utility model relates to transformer, is specifically related to the transformer of coil integration.
Background technology
The driving voltage of usual electronic equipment requires lower, but the voltage that external power source provides is still higher, therefore adopts the voltage of transformer switched power supply voltage needed for electronic equipment.Transformer comprises the first and second coil changing voltages, and the first and second coils are fastened on transformer framework; But the automation mounting structure difficulty of coil is large, causes transformer production ability to decline.Therefore a kind of transformer framework is developed and coil draw bail is necessary.And coil need cover dielectric film two winding internal from, but because coil covering insulation film, cause the increase of transformer whole volume, and be difficult to miniaturization.
Utility model content
For the problems referred to above, problem to be solved in the utility model is to provide a kind of coil surface not to be needed to arrange insulation coverlay, the transformer of volume miniaturization.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of coil integrated transformer, and transformer comprises transformer framework, primary coil, secondary coil and iron core; Described primary coil and iron core are all fixed in transformer framework, and described secondary coil is positioned at the inside of transformer framework.
As preferably, described transformer framework is horizontal H type shape, and comprise upper part and lower part, centre is provided with iron core hole; Described iron core is arranged in iron core hole.
As preferably, described secondary coil comprises the first secondary coil and second subprime coil, described first secondary coil is arranged in the upper part of transformer framework, described second subprime coil is arranged in the lower part of transformer framework, do not need on the surface of secondary coil to cover insulation film, reduce the volume of transformer whole.
As preferably, described secondary coil and transformer framework are overall structures, and the end of secondary coil is positioned at outside transformer framework, is connected with external circuit.
As preferably, coil width, the number of turn of the coil width of described first secondary coil, the number of turn and second subprime coil are determined according to concrete performance.
As preferably, shape and the iron core hole shape of described iron core may be the same or different.
As preferably, the described lower surface of transformer framework upper part and the upper surface of lower part are the flat surfaces be parallel to each other, described primary coil is arranged around transformer framework, between the lower surface and the upper surface of lower part of the upper part of transformer framework, separates with iron core; Separate completely between described primary coil and secondary coil, reduce the leakage inductance problem of transformer to a great extent.
As preferably, in described transformer, also ancillary coil can be provided with.
The utility model beneficial effect, in the utility model structure, secondary coil and transformer framework are the structures of one, and effectively improve production efficiency, secondary coil and primary coil effectively separate, and effectively reduce leakage inductance.
