Technical field
The utility model relates to transformer application field, especially a kind of low magnetic leakage high frequency transformer.
Background technology
According to Faraday's electromagnetic induction law, in alternating current circuit, the magnetic line of force is time dependent, and therefore, the height of voltage and the size of electric current also can change thereupon, and people have manufactured various forms of transformer according to this principle.In recent years, switch power technology is just towards aspect development such as efficient, energy-conservation, safety, environmental protection, volume are little.In the Switching Power Supply of supreme frequency power transformer, high frequency transformer is one of core component, in the key technology that the design of high frequency transformer is Switching Power Supply, whether high frequency transformer designs reasonable, can have influence on the cost of shape power supply, volume, stability, electromagnetic interference, radiated noise, EMI filtering, power output, conversion efficiency etc.The core structure of traditional transformer is substantially: " E " type, " C " type or " O " type structure, the structure of " circuit encirclement magnetic circuit " due to what adopt between these magnetic core and coils, the partial magnetic field of coil both sides can not be fully utilized, therefore, magnetic flux leakage is comparatively large, causes that the efficiency of transformer is low, volume is large, cost is high, produces magnetic interference very large when serving power supply, temperature is too high, and other parts can be caused easily to damage; In addition its structural design defective tightness, easily there is the problems such as leakage field, leakage inductance, iron loss, exciting current are large, radiating condition is poor, efficiency low noise is large, and along with the raising of frequency, even also there is even more serious collection skin, become the problems such as table and proximity effect, bad injury will be caused to human body, in addition, assembling is enough in bother with installation, is unfavorable for safeguarding.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide a kind of low magnetic leakage high frequency transformer.
For realizing this technical purpose, scheme of the present utility model is: a kind of low magnetic leakage high frequency transformer, comprises magnetic core, coiling group, inner ring, convex cylindrical, fixed part, opening, the first upper buckle portion, the first lower buckle portion, the second upper buckle portion, the second lower buckle portion and vertical portion; Described coiling group comprises ring winding seat and is wrapped in the coil on ring winding seat; Described magnetic core comprises upper cover, lower cover and fixture; Described fixed part has the bottom outer edge that four and the center of circle are symmetricly set in ring winding seat; What described opening was arranged at corresponding fixed part leaks outside on the magnetic core of direction; Described inner ring is arranged at ring winding seat central authorities; Described convex cylindrical is arranged at lower cover cavity bottom, and the inner ring being inserted in ring winding seat is inner; Described fixture is connected upper cover and lower cover with the first lower buckle portion with the second upper buckle portion and the second lower buckle portion being arranged at upper cover top and lower cover bottom respectively with the first upper buckle portion of bottom by being arranged at fixture top; Described vertical portion is arranged at fixture bottom.
Further, described anchor structure is fastening structure.
Further, described opening is provided with four altogether on the direction magnetic core that leaks outside of fixed part.
Compared with prior art, the beneficial effects of the utility model are: this low magnetic leakage high frequency transformer, global design is reasonable, closely, magnetic core is made up of upper cover and lower cover, coil is completely within it coated, can reduce because of leakage field, leakage inductance and the radiated noise produced, improve the reliability of product, therefore, also improve conversion efficiency and the power output of power supply, energy savings, magnetic field energy is fully utilized, greatly reduce other damage parts, will allow the efficiency that overall spare part provides more stable, and can effectively by the leakage field of transformer, leakage inductance, collection skin, become table and proximity effect be reduced to minimum level, reduce human injury, fixture adopts fastening structure, ingeniously upper cover and lower cover is mutually fastened, and forms the magnetic core of integral structure, and volume is little, cooperations is firm, and convenient for assembly and dismantle, and while reducing costs, promoting productivity ratio, maintains easily again, overall structure is simple, and volume is little, easily manufactured, and power is high, uses for being applicable to comparatively Miniature Power Unit and adapter.
