Topic, but there are problems that leakage field, assembling.
The content of the invention：
The technical problem to be solved is to provide a kind of new inductance core, should integrated conventional combination inductance sky
Between utilization rate and the simple advantage of coiling, can solve again leakage field, assembling location difficulty the problems such as.
For this purpose, the present invention is employed the following technical solutions：
A kind of new high-frequency inductor magnetic core, including the first magnetic core, the second magnetic core and it is connected to the first magnetic core and the second magnetic core
Between column magnetic core, the first magnetic core, the second magnetic core and column magnetic core are connected as a single entity, it is characterised in that：
In the joint of the first magnetic core, the second magnetic core and column magnetic core, the first magnetic core and the second magnetic core have location hole, post
The end of shape magnetic core is embedded in location hole, and there is air gap in joint, is easy to change the hardness of inductance.
Further, there is air gap between the end face of the end and the bottom hole of location hole.Air gap also is present in connecting
Other positions at place, but, the air gap between end face and bottom hole is easier to be conditioned.
In force, can be that the joint of all first magnetic cores, the second magnetic core and column magnetic core all has air gap, also may be used
Can be that the joint of the magnetic core of part first, the second magnetic core and column magnetic core has air gap.
The column magnetic core is single cylinder or the column magnetic core built up for strip magnetic core.
First magnetic core, the second magnetic core can be other arbitrary shapes such as cylinder body shape, template, as long as being suitable to arrange positioning
Hole.
First magnetic core, the second magnetic core and column magnetic core are respectively identical material or different materials, the material bag
Include iron sial, iron silicon, ferrocart core, amorphous, ferrite.
Due to adopting technical scheme, high-frequency inductor magnetic core of the present invention both integrated conventional combination inductance space utilizations
Rate and the simple advantage of coiling, the problems such as leakage field can be solved again, location difficulty is assembled, while be also convenient for adjusting air gap, by adjusting
Air gap adjusts inductance hardness.
