Abstract
The utility model discloses a magnetic core transformer, including skeleton, magnetic core and wire rod, be equipped with the magnetic core hole in the middle of the skeleton, magnetic core hole upper and lower parts do not inserts a magnetic core, the magnetic core is " III " shape, and two upper and lower magnetic core coincide are inserted the magnetic core hole and are used the electric tape winding fixed, be equipped with the wire winding groove on the skeleton, the winding the wire rod is equipped with one row 4 stitch respectively in the bottom both sides of skeleton for the wire that the wire rod was drawn is twined, fixed and weld. The utility model discloses with the high reduction of transformer, with the increase of magnetic core of transformer sectional area, in the transformer with the volume, can bear 2 times of electric energy power converting, satisfy ultra -thin, the high power density demand of power, be equipped with 8 pins, the ability wide application is in non - isolation, isolation, the multiple circuit of pure inductance.
Description
Technical field
The utility model relates to field of electronic devices, relates in particular to a kind of core transformers.
Background technology
Transformer, as the core component of driving power, to the conversion efficiency of electric energy, has very important effect the service life of power supply, is applied at present power technique fields, and transformer exists the high power density problem that is difficult to meet under small size.
Utility model content
The purpose of this utility model is to provide a kind of core transformers, meets ultra-thin, the high power density demand of power supply.
To achieve these goals, the technical scheme that the utility model provides is:
A kind of core transformers, comprise skeleton, magnetic core and wire rod, in the middle of described skeleton, be provided with magnetic core hole, a magnetic core is inserted respectively in top and the bottom, magnetic core hole, and described magnetic core is " Ш " shape, and upper and lower two magnetic core superimposed insertion magnetic core holes are also used insulating tape to be fastened, described skeleton is provided with winding slot, be wound around described wire rod, be respectively equipped with row's 4 stitch in the two bottom sides of skeleton, for the wire being wound around, fixing and welding wire is drawn.
Described wire rod is enamel-covered wire, three layer insulation wire, copper cash or excitation wire.
Compared with prior art, the utility model reduces transformer height, magnetic core of transformer sectional area is increased, in the transformer of same volume, can carry 2 times of electric energy power transfer, ultra-thin, the high power density demand that meet power supply, be provided with 8 pins, can be widely used in non-isolation, isolation, the multiple circuit of pure inductance.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment core transformers.
Fig. 2 is the schematic diagram of the magnetic core of the utility model embodiment core transformers.
Fig. 3 is the structural representation of the skeleton of the utility model embodiment core transformers.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
With reference to figure 1, Fig. 2 and Fig. 3, the utility model embodiment provides a kind of core transformers, comprise skeleton 12, magnetic core 11 and wire rod 13, in the middle of described skeleton 12, be provided with magnetic core hole 121, a magnetic core 11 is inserted respectively in 121 top and the bottom, magnetic core hole, described magnetic core is " Ш " shape, upper and lower two the superimposed insertion magnetic core of magnetic core 11 holes 121 are also used insulating tape to be fastened, described skeleton 12 is provided with winding slot 122, be wound around described wire rod 13, be respectively equipped with row's 4 stitch 14 in the two bottom sides of skeleton 12, for being wound around, the wire fixing and welding wire is drawn, whole transformer height is reduced to 10mm, magnetic core sectional area increases 1.5 times.
Described wire rod is enamel-covered wire, three layer insulation wire, copper cash or excitation wire.
In conjunction with Fig. 1-3, the utility model expands transformer framework cavity, transformer height is reduced to 10mm, magnetic core of transformer sectional area is increased to 1.5 times, in the transformer of same volume, can carry 2 times of electric energy power transfer, meet ultra-thin, the high power density demand of power supply, be provided with 8 pins, can be widely used in non-isolation, isolation, the multiple circuit of pure inductance.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
