Mainly whether there is or not skeleton Wound-rotor type and there is two kind pattern of skeleton Wound-rotor type formula around line transformer.The two be tradition around The product of line inductance type;The volumetric spaces that the transformer of traditional wire-wound inductor type occupies are larger, and heat dissipation performance is poor, and And structure is more complicated, production efficiency is not high.
Invention content
To solve the above problems, the utility model provides a kind of novel copper foil transformer, the space occupied is small, structure Simple and production efficiency is high.
To achieve the above object, the technical solution adopted in the utility model is:A kind of novel copper foil transformer, feature exist In, including a center pillar magnetic core and several planar coils, wherein the planar coil middle is surrounded by an open circles, And connection terminal is respectively arranged on the both ends of the planar coil, plurality of planar coil it is overlapped and constitute annulus around Group, is equipped with magnetic core stem at the center of the center pillar magnetic core, the center pillar magnetic core be separately positioned on annulus winding upper surface and Lower surface, the two magnetic core stems are plugged at the center of annulus winding.
Specifically, the both sides of the center pillar magnetic core are equipped with magnetic core block, and the magnetic core block is fitted in the side of annulus winding On face.
Specifically, further include transformer case, the transformer case is fitted in the surface of magnetic core block.
Specifically, the planar coil is suppressed by copper foil.
Specifically, the upper and lower surface of planar coil is equipped with insulation glue surface.
The beneficial effects of the utility model are:It is excellent using the planar coil of platypelloid type relative to traditional round copper wire Point is limited in linear distance, can around more the number of turns, to promote whole inductance value and reduce the sky of occupancy Between volume, and the planar coil of platypelloid type, relative to typical round copper wire, heat dissipation area is significantly increased, and is conducive to preferably Heat dissipation;The magnetic core stem in the middle part of two center pillar magnetic cores is docked after passing through at the center of annulus winding and is formed simultaneously, is reduced magnetic and is returned The utilization rate on road and electrical circuit, while wire winding is simple, reduces the labor intensity of worker, improves production efficiency;So that Entire copper foil transformer has light-weight, efficient, a small feature of noise, and can by more high current, high-power, low-loss, Higher frequency is adapted to, more high q-factor is obtained.

Drawing reference numeral explanation:1- planar coils;11- coil first ends;12- coil second ends;The connections of 111- first Terminal;121- second connection end;2- center pillar magnetic cores;21- magnetic core stems;22- magnetic core blocks.
Specific implementation mode
Refering to Figure 1, in this embodiment, a kind of novel copper foil transformer, including a center pillar magnetic core 2 with And several planar coils 1, wherein 1 middle of the planar coil is surrounded by an open circles, and the two of the planar coil 1 Connection terminal is respectively arranged on end, plurality of planar coil 1 is overlapped and constitutes annulus winding, the center pillar magnetic core 2 Center at be equipped with magnetic core stem 21, the center pillar magnetic core 2 is separately positioned on the upper and lower surface of annulus winding, and described Magnetic core stem 21 is plugged at the center of annulus winding.
The wherein described annulus winding includes multiple overlapped planar coils 1, and the both ends of the planar coil 1 are respectively Coil first end 11, coil second end 12, coil first end 11 are arranged in the top of coil second end 12, institute It states coil first end 11 and is equipped with the first connection terminal 111 for extending to the right, coil second end 12 is provided with to be extended to the left Second connection end 121;The first connection terminal 111 and second connection end 121 wherein on each planar coil 1 respectively with Power supply pcb board is electrically connected.
Relative to traditional round copper wire, it is limited in linear distance using 1 advantage of planar coil of platypelloid type, More the number of turns can be built to obtain, to promote whole inductance value and reduce the space occupied volume, and the plane of platypelloid type Coil 1 is significantly increased relative to typical round copper wire, heat dissipation area, is conducive to preferably radiate;Two center pillar magnetic cores 2 simultaneously The magnetic core stem 21 at middle part is docked after passing through at the center of annulus winding and is formed, and reduces the utilization rate of magnetic loop and electrical circuit, Wire winding is simple simultaneously, reduces the labor intensity of worker, improves production efficiency;So that entire copper foil transformer has weight Light, efficient, the small feature of noise is measured, and can be adapted to higher frequency by more high current, high-power, low-loss, obtain higher Q values.
Specifically, the both sides of the center pillar magnetic core 2 are equipped with magnetic core block 22, and the magnetic core block 22 is fitted in annulus winding Side on.Magnetic core block 22 can play the position of firm center pillar magnetic core 2 and annulus winding, increase the stabilization of the two connection Property.
Specifically, further include transformer case, the transformer case is fitted in the surface of magnetic core block 22.Outside transformer Shell can make basic protective effect with center pillar magnetic core 2.
Specifically, since each planar coil 1 is upper and lower closed assembly, there are gap, and the window of magnetic core up and down Utilization rate is not also high, and this structure forms radiator window.Conducive to heat dissipation, it is less than 300 DEG C in rated for service Wen Sheng.To big It is big to reduce core loss, and heat ageing phenomenon is not present, product work is more stable.
Specifically, the planar coil 1 is suppressed by copper foil.Copper foil is a kind of cloudy matter electrolysis material, is deposited in electricity A floor on the plate basal layer of road is thin, continuous metal foil;It is because copper foil has using copper foil as the material of planar coil 1 is made There is excellent conduction, and the effect of electromagnetic shielding is provided, performance is stablized.
Specifically, the upper and lower surface of planar coil 1 is equipped with insulation glue surface.The glue surface that insulate is in each planar line Circle 1 plays the role of insulation, ensures to work normally between each planar coil 1.
Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine It protects in range.
