Stacking after neat is laminated after second group of transformer plate edge alignment, second group of transformer plate is put into and first group of transformer plate mirror
It is laminated again with first group of transformer plate after face is symmetrical;
Multi-disc has the insulation spacer of central through hole, is inserted into a piece of insulation spacer between any two panels transformer plate, absolutely
The through-hole of edge gasket and the through-hole of transformer plate are corresponding, the edge of insulation spacer without departing from transformer plate edge so that becoming
Depressor piece and insulation spacer form transformer plate structure;
The identical magnetic core of a pair of of planform, it is one among recess that a part of magnetic core shape, which is rendered as concave,
Two magnetic cores are relatively clasped transformer plate structure by a protrusion, and the protrusion of magnetic core is just embedded in by transformer plate through-hole and absolutely
In the through-hole for the transformer plate structure that edge shim through bore is formed.
The transformer plate has connection end, has multiple through-holes on connection end, so that after transformer plate stacking
The connection end of the transformer plate structure of formation forms multiple screw holes, plus the same briquetting with screw hole on screw hole, uses
Screw passes through the screw hole that briquetting connects end with transformer plate structure, is subsequently passed through the screw hole of pcb board, transformer plate structure is consolidated
It is scheduled on pcb board, there is on corresponding position same screw hole on pcb board.
It is equipped with welding hole in the other end relative to connection end of the transformer plate, between welding hole and connection end
It is the central through hole of transformer plate,
After transformer plate is laminated and to form transformer plate structure, transformer plate structure is also just provided with welding connecting hole, uses
Copper post passes through the welding connecting hole, is welded with scolding tin.
The shape of the transformer plate is left and right asymmetric body, the right side of the right side likeness in form Ω of transformer plate, transformation
The left side of device piece is similar to the left side of oblique shovel face.
Power transformer structure of the invention compared with prior art, has the advantages that
1, composed part is mold members, and machine adds part and universal standard part, convenient for producing in enormous quantities, has production effect
The advantages that rate is high, and precision is high, and versatility is good, at low cost.
2, it is designed due to simplifying structure, reduces number of parts, thus assembling flow path is simpler, used device, manpower
Deng less, therefore, structure space service efficiency optimized, reduce the cost of transformer.
3, the structure design of transformer plate of the invention, due to being identical structure in primary and secondary side, becoming
During the specific type selecting of depressor, only actual transformer the piece number need to be carried out according to actual function needs (mainly turn ratio number)
Amount adjustment, therefore, flexible and flexibility is higher.
4, in transmission high-current circuit, since electric current is very big, reducing contact impedance becomes reduction calorific value emphasis
The factor of consideration, using screw and briquetting mutually matched structure design, as far as possible reduction contact impedance in the present invention, thus
Product fever is reduced, product efficiency is improved.
5, the transformer plate in the present invention is that electric conductivity is very high, the extraordinary red copper material of flexibility, according to reality
It needs after being superimposed multi-layer transformer piece (mainly turn ratio number), when transformer and pcb board assemble, very due to it
Softness therefore, there is no need to additional mold and carry out bending again.
