Abstract
The invention discloses a secondary iron core of a leakage transformer. The secondary iron core comprises end part iron cores and middle iron cores, wherein the end part iron cores are arranged at the upper end and lower end respectively; the middle iron cores are arranged between the two end part iron cores; an air gap is formed between the every two middle iron cores; an air gap is also formed between the end part iron core and the middle iron core close to the end part iron core; a thin stainless steel pull plate is arranged on each of front and back sides of the secondary iron core; and an insulated plate is arranged on the outer side of the thin stainless steel pull plate. According to the secondary iron core of the leakage transformer, parameter needs of the leakage transformer can be met while compact structure is ensured, so that structural reasonability and stability are ensured.
Description
Technical field
The present invention relates to a kind of secondary iron core of leakage transformer.
Background technology
Leakage transformer belongs to the category of leakage field boosting dry-type transformer, sharply changes and requires progressively to tend towards stability in the electronic equipment of state, as the equipment such as fluorescent lamp power supply, ion pump power for load; It is comparatively large that this class load shows as impedance when starting working, and needs higher transient voltage; And when steady operation, load impedance is less, need load current be limited in permissible value, can normally work; Existing leakage transformer ubiquity unreasonable structure, causes taking up space comparatively large, the problems such as radiating effect is poor; Therefore, now design a kind of space for the problems referred to above and account for smaller, the leakage transformer of perfect heat-dissipating, and need to design its corresponding secondary iron core.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the secondary iron core proposing a kind of leakage transformer.
Technical solution of the present invention is achieved in that a kind of secondary iron core of leakage transformer, comprise end iron core and middle iron core, end iron core is separately positioned on upper and lower two ends, multiple middle iron core is arranged between two end iron cores, be provided with air gap between iron core in the middle of every two, between end iron core and close middle iron core, be also provided with air gap; The both sides, front and back of described secondary iron core are provided with thin stainless steel arm-tie, and the arranged outside of thin stainless steel arm-tie has insulation board.
Preferably, the air gap between described end iron core and middle iron core is less than the air gap between middle iron core.
Preferably, described end iron core has 2, and middle iron core has 19.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The secondary iron core of leakage transformer of the present invention, while guarantee compact conformation, can meet the parameter needs of leakage transformer, ensure that reasonability and the stability of structure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the front view of the secondary iron core of a kind of leakage transformer of the present invention;
Accompanying drawing 2 is the left view of the secondary iron core of a kind of leakage transformer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As shown in accompanying drawing 1-2, the secondary iron core of a kind of leakage transformer of the present invention, comprise iron core 32 in the middle of 2 end iron cores 31 and 19,2 end iron cores 31 are separately positioned on upper and lower two ends, in the middle of 19, iron core 32 is arranged between two end iron cores 31 successively, be provided with 6mm air gap 33 between iron core 32 in the middle of every two, between end iron core 31 and close middle iron core 32, be also provided with 4mm air gap 33; The both sides, front and back of described secondary iron core 3 are provided with the thin stainless steel arm-tie 34 of 2mm, and the arranged outside of thin stainless steel arm-tie 34 has the 1mm insulation board 35 of FR4 specification.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
