Abstract
The invention discloses a UIW magnetic core used for a filter. Magnetized cuboid permanent magnets (3) and (4) are placed between two side legs of a U-shaped magnetic core (1) and an I-shaped magnetic core (2). The magnetic core is prepared from a ferrite material through sintering or metal soft magnetic powder through pressing.
Description
Technical field
The present invention relates to a kind of magnetic core, more particularly to it is a kind of for wave filter UIW magnetic cores.
Background technology
Wave filter needs to use a kind of complex-shaped magnetic core, and this often brings blank and is difficult to compressing problem, needs to use baroque special press, and this is both unfavorable for producing in enormous quantities, and production cost is considerably increased again.Further, since shape of product is complicated, cause green density to be difficult to uniformly, product is easily deformable and become waste product when sintering, and substantially reduces product percent of pass, causes production high cost, to manufacturing very big waste is brought.In order to solve this problem, by being optimized design to core const ruction, so that magnetic core can be manufactured by high-volume low cost.
The content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, there is provided one kind can be applied to receiving device, and the magnetic core that can be manufactured by high-volume low cost.
The technical solution adopted in the present invention is：One kind is used for wave filter UIW magnetic cores, in U shaped magnetic core（1）Two side legs and I type magnetic cores（2）Between, it is placed with the cuboid permanent magnet for having magnetized（3）、（4）.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
The invention has the beneficial effects as follows：Due to magnetic core simple shape, it is possible to use simplest mould is pressed, and production efficiency can be greatly improved with one-mold multiple-member, the present invention also efficiently solves that traditional magnetic core is easily deformable, while the low problem of product percent of pass.
Description of the drawings
With reference to the accompanying drawings and examples the invention will be further described.
Fig. 1 is single magnetic core schematic diagram, in figure（1）For U shaped magnetic core,（2）For I type magnetic cores,（3）、（4）For the cuboid permanent magnet for having magnetized.
Specific embodiment
One kind is used for wave filter UIW magnetic cores, in U shaped magnetic core（1）Two side legs and I type magnetic cores（2）Between, it is placed with the cuboid permanent magnet for having magnetized（3）、（4）.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.Magnetic core can be pressed using simplest mould, and due to simple shape, can greatly improve production efficiency with one-mold multiple-member.The present invention also efficiently solves that traditional magnetic core is easily deformable, while the low problem of product percent of pass.
Claims (2)
1. it is a kind of to be used for wave filter UIW magnetic cores, it is characterized in that：In U shaped magnetic core（1）Two side legs and I type magnetic cores（2）Between, it is placed with the cuboid permanent magnet for having magnetized（3）、（4）.
2. a kind of according to claim 1 to be used for wave filter UIW magnetic cores, the magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
