The simple easily shaping of processing, the suppression qualification rate is high, forming pressure is big, and finished product magnetic core density is high, and magnetic core DC bias ability reinforce satisfies the high sensibility reciprocal high power density application demand of heavy current, U type magnetic core and the perfect adaptation of pole magnetic core during the equipment, the magnetic leakage can be absorbed by U type magnetic core, and the inductance leakage inductance is little, and the performance is high, required die cost hangs down mould long service life, and the magnetic core processing cost is low.
Description
Technical field
This utility model is related to a kind of EQ types magnetic core.
Background technology
In traditional EQ types magnetic core, magnetic core is made up of two identical EQ types magnetic cores to spelling, and the EQ type magnetic cores have problems with：
1st, molding is difficult when the EQ types magnetic core is suppressed, and suppresses qualified interest rate low；2nd, the EQ type form forming magnetic core pressure is low, and pressed density difference causes
Its direct current biasing ability, sensibility reciprocal is low under high current, it is difficult to meet the high sensibility reciprocal high power density application demand of high current；3rd, EQ types
Magnetic core is yielding in high annealing, has air gap during assembling in the middle of two EQ magnetic cores, and the leakage inductance of inductance becomes big, causes inductive
Can be deteriorated；4th, the EQ types magnetic core mould high cost and die life is low, causes the high processing costs of magnetic core.
Utility model content
For the deficiencies in the prior art, this utility model aims to provide a kind of EQ types magnetic core, processes simple easy-formation, compacting
Qualification rate is high；Briquetting pressure is big, and finished product magnetic core density is high, and magnetic core direct current biasing ability is strong, meets the high sensibility reciprocal high power of high current
Density applications demand；U-shaped magnetic core and pole magnetic core perfect adaptation during assembling, leakage field can be absorbed by U-shaped magnetic core, and inductance leakage inductance is little,
Performance is high；Die needed low cost die life is long, and magnetic core processing cost is low.
It is of the present utility model to be achieved through the following technical solutions.
A kind of EQ types magnetic core, including two U-shaped magnetic cores, pole magnetic cores, the U mouths of two U-shaped magnetic cores coordinate to be installed, and two
Opposite face in the individual U-shaped magnetic core is provided with the circular mounting groove coordinated with the pole magnetic core, and the pole magnetic core is arranged on
In the circular mounting groove.
Preferably, the circular mounting groove is arranged in the middle of the U-shaped magnetic core.
Preferably, the U mouths inner side of the U-shaped magnetic core is cambered surface, and the cambered surface is concentric with the circular mounting groove.
Preferably, the height of the pole magnetic core be equal to the circular mounting trench bottom to the U mouths of the U-shaped magnetic core away from
From twice.
Compared with prior art, the utility model has the advantages that, this utility model using two to spell U-shaped magnetic cores in the middle of
Circular mounting groove is set, pole magnetic core is mounted in mounting groove, replace traditional two to the EQ type magnetic cores spelled, bring following excellent
Point：
1st, U-shaped magnetic core and pole magnetic core process simple easy-formation, and compacting qualification rate is high；
2nd, U-shaped magnetic core and pole form forming magnetic core pressure are big, and finished product magnetic core density is high, and magnetic core direct current biasing ability is strong, meet
The high sensibility reciprocal high power density application demand of high current；
3rd, U-shaped magnetic core and pole magnetic core do not allow yielding, magnetic core flatness height, are provided with U-shaped magnetic core and match somebody with somebody with pole magnetic core
The circular mounting groove of conjunction, U-shaped magnetic core and pole magnetic core perfect adaptation during assembling, leakage field can be absorbed by U-shaped magnetic core, inductance leakage inductance
Little, performance is high；
4th, U-shaped magnetic core and the die needed low cost die life of pole magnetic core are long, and magnetic core processing cost is low.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment, but not as of the present utility model
Limit.
As shown in Figure 1 to Figure 2, a kind of EQ types magnetic core, including two U-shaped magnetic cores (1), pole magnetic cores (2), two U
The U mouths (101) of type magnetic core (1) coordinate to be installed, and the opposite face in two U-shaped magnetic cores (1) is provided with and the pole magnetic core (2)
The circular mounting groove (102) of cooperation, the circular mounting groove (102) is arranged in the middle of the U-shaped magnetic core (1), the U-shaped magnetic core
(1) U mouths (101) inner side is cambered surface (103), and the cambered surface (103) is concentric with the circular mounting groove (102), the pole
Magnetic core (2) is arranged in the circular mounting groove (102), and the height of the pole magnetic core (2) is equal to the circular mounting groove
(102) twice of the bottom to the distance of the U mouths (101) of the U-shaped magnetic core (1).
The foregoing is only this utility model preferred embodiment, not thereby limit embodiment of the present utility model and
Protection domain, to those skilled in the art, should can appreciate that in all utilization this utility model description and diagram
Scheme obtained by holding done equivalent and obviously changing, should be included in protection model of the present utility model
