Description
Technical field
The utility model is related to a kind of exoskeletal high frequency transformer.
Background technology
Conventional high frequency transformer is constituted by skeleton, magnetic core and coil, and skeleton will take certain space, cause transformation
The volume of device can become big, and be difficult to reduce manufacturing cost.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that above-mentioned prior art is present, and provides a kind of exoskeletal high frequency
Transformer, the design of its exoskeletalization can reduce the volume of transformer, and reduce manufacturing cost.
The purpose of this utility model is realized in：
A kind of exoskeletal high frequency transformer, including core assembly and winding coil, its architectural feature is, core assembly
Be provided with the magnetic core axle in horizontally set, winding coil along magnetic core axle axial direction layer around thereon, core assembly bottom is solid
Surely insulation board, some leads that winding coil is drawn pass insulation board and form terminals on insulation board.
The core assembly includes left magnetic core and right magnetic core, and two magnetic cores are symmetrical expression or asymmetric, and two magnetic cores are by absolutely
Edge adhesive tape and/or fixing glue are combined.
The core assembly constitutes three pieces of upper, middle and lower magnet ring, and middle magnet ring is magnetic core axle, and insulation board is held within
The bottom of the magnet ring of lower section.
The section of the magnetic core axle is in for circle；The section of other two pieces of magnet rings is fan-shaped or arc, and they are symmetrical
Two magnet rings of formula.
Fixed by fixing glue between the core assembly and insulation board.
Fixed by fixing glue between the lead and insulation board.
If the winding coil has dried layer, go back layer on every layer of winding coil and be wound with insulating paper, winding coil and magnetic core axle it
Between also be provided with insulating paper.
A diameter of 0.01-0.10mm of the coiling of the winding coil.
The beneficial effects of the utility model are as follows：
By above-mentioned technological improvement, in the structure of high frequency transformer in-discard skeleton, which can be the space of skeleton profit
Use, the power of unit volume is higher, and be conducive to saving manufacturing cost.
The utility model can be applied on various high frequency transformers, and especially powerful high frequency transformer, can apply
Scope is big.Which adopts full enclosed technique, and pressure and insulation is by up to most tight standard.All material adopts F levels（155
Degree））Above temperature resistant grade, performance and is just greatly improved with the life-span.
Description of the drawings
Fig. 1 is the stereogram of one embodiment of the utility model assembling.
Half sectional views of the Fig. 2 for Fig. 1.
Exploded views of the Fig. 3 for one embodiment of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.
Referring to Fig. 1-Fig. 3, this exoskeletal high frequency transformer, including core assembly and winding coil 2, set on core assembly
Have a magnetic core axle 13 in horizontally set, winding coil 2 along magnetic core axle 13 axial direction layer around thereon, core assembly bottom is solid
Surely insulation board 3, some leads 21 that winding coil 2 is drawn pass insulation board 3 and form terminals 22 on insulation board 3.
Further, core assembly includes left magnetic core 11 and right magnetic core 12, and two magnetic cores are symmetrical expression or asymmetric（This reality
Example is applied for symmetrical expression）, two magnetic cores pass through insulating tape and fixing glue 4 is combined.Core assembly can form slight air gap,
Slight air gap is used for improving magnetic core anti-saturation ability, while two magnetic core tight bonds are substantially reduced due to magnetic substance together
The abnormal sound that Shen contracting is caused.
Further, core assembly constitutes three pieces of upper, middle and lower magnet ring, and middle magnet ring is magnetic core axle 13, and insulation board 3 is admittedly
It is scheduled on the bottom of underlying magnet ring.Three pieces of magnet rings can form three sections and cut gap, can avoid the vortex of internal generation, not have
Air gap burns out copper cash.
Further, the section of magnetic core axle 13 is in for circle；The section of other two pieces of magnet rings is fan-shaped or arc, and they
Two magnet rings for symmetrical expression.
Further, fixed by fixing glue 4 between core assembly and insulation board 3；Also lead between lead 21 and insulation board 3
Cross fixing glue 4 to fix.Make preferably to be fixed together between core assembly and insulation board 3, and lead 21 is also fixed
On insulation board 3, it is easy to tin and wiring on terminals 22.
Further, if winding coil 2 has dried layer, go back layer on every layer of winding coil 2 and be wound with insulating paper, winding coil 2 with
Insulating paper also is provided between magnetic core axle 13, conventional skeleton is eliminated even if ensure that, can also meet the use requirement of insulation.
Further, a diameter of 0.01-0.10mm of the coiling of winding coil 2, preferably uses a diameter of 0.05mm-
As coiling, the copper cash of 0.06mm disclosure satisfy that switch operating frequency is high, the occasion that use environment temperature is high.
Above disclosed is only preferred embodiment of the present utility model, rather than is limited with this of the present utility model
Claims, according to the equivalent variations that is made in the utility model protection domain, still belong to what the utility model was protected
Scope.
