Abstract
Riešenie sa týká komipaktného minitransformátora. Podstatou riešenia je, že v kostře je uložené jádro· tvořené feritom alebo traíoplechmi tvaru E—E, ktoré sú fixované elektroizolačným pružným stahovacími rámom a spevnené lepidlom naneseným medzi styčnými plochami jadra a elektroizolačného pružného sťahovacieho rámu.The solution relates to a compact minitransformer. The essence of the solution is that in the skeleton is a core made of ferrite or trays shaped E-E, which are fixed by electrical insulation with a flexible clamping frame and reinforced with an adhesive applied between the interfaces core and electroinsulating surfaces a flexible draw frame.
Description
Vynález sa týká riešenia kompaktného minitransformátora.The present invention relates to a compact mini-transformer.
Doiteraz boli u miniatúrnych transformátorov používané jadrá a trafoplechov tvaru Β—E a fixované pružnou plechovou objímkou na kostru transformátora. U feritových jadier boli tieto obalované izolačnou papierovou páskou a stahované plechovou páskou mechanicky spojenou priečni!kom.Doiteraz cores and op-E-shaped transformers were used in miniature transformers and fixed with a flexible sheet metal sleeve to the transformer frame. In the case of ferrite cores, these were wrapped with insulating paper tape and pulled with a metal tape mechanically connected by a cross-member.
Nevýhodou týchto riešení je zložitá montáž, nevhodná pre automatizáciu výroby, nedostatečné stiahnuté jadra, čo výrazné ovplyvňuje parametre transformátora, najma indukčnost a u trafoplechov tvaru Β—E sa používali dva druhy finančně nákladných razných nástrojov.The disadvantage of these solutions is complex assembly, unsuitable for production automation, insufficient cores, which significantly affects transformer parameters, especially inductance, and u — E transformers have two types of costly punching tools.
Vyššie uvedené nevýhody odstraňuje kompaktný mlnitransformátor podlá tohoto vynálezu, ktorého, podstatou je, že v kostře je uložené jádro tvořené feritom alebo trafoplechmi tvaru Ε—E, ktoré sú fixované elektroizolačným pružným stahovacím rámom a spevnené lepidlom naneseným medzi styčnými plochami jadra a elektroizolačného pružného sťahovacieho rámu.The above-mentioned disadvantages are overcome by the compact mill transformer according to the invention, which consists in the fact that a core consisting of ferrite or Ε-E-shaped transformers is fixed in the frame, fixed by an electro-insulating elastic contraction frame and reinforced by adhesive applied between .
Kompaktný mlnitransformátor podlá vynálezu tvoří kompaktný nerozoberatefný celok a jeho konštrukcia umožňuje automátizáciu montáže.The compact mill transformer according to the invention forms a compact, non-disassembling unit and its construction allows automation of assembly.
Na pripojenom výkrese na obr. 1 je znázorněné příkladně riešenie kompaktného minitransformátora v čiastočnom řeze. Kompaktný mlnitransformátor pozostáva z kostry 1, na ktorej je uložené primárné 2 a, sekundárné 3 vinutie. Jádro 4 tvořené feritom, alebo trafoplechmi tvaru Ε—E je uložené v kostře 1 fixované elektroizolačným pružným stahovacím rámom 5 a spevnené lepidlom 6, naneseným medzi styčné plochy jadra 4 a elektroizolačného pružného sťahovacieho rámu 5.In the attached drawing of FIG. 1 is a partial cross-sectional view of a compact mini transformer. The compact mill transformer consists of a frame 1 on which the primary 2 a, the secondary 3 windings are mounted. The core 4 formed by ferrite or f-E-shaped transformer plates is embedded in the frame 1 fixed by an electro-insulating flexible frame 5 and reinforced by an adhesive 6 applied between the contact surfaces of the core 4 and the electro-insulating flexible frame 5.
Montáž kompaktného minitransformátora sa uskutočňuje tak, že do kostry 1 s primárným 2 a sekundárným 3 vinutím sa zasunie jádro 4 z feritu alebo trafoplechov tvaru Ε—E. Na hrany jadra 4 sa nanesie lepidlo a celok sa zafixuje elektroizolačným pružným stahovacím rámom 5, čím sa vytvoří kompaktný nerozoberatefný celok.The assembly of the compact mini-transformer is carried out by inserting a core 4 of ferrite or Ε-E-shaped transformer sheets into the frame 1 with primary 2 and secondary 3 windings. An adhesive is applied to the edges of the core 4 and the assembly is fixed by an electro-insulating resilient clamping frame 5 to form a compact, non-disassembling assembly.
