Abstract
It is used for proximity switch TX magnetic cores the invention discloses one kind, the magnetic core is by 3 font side legs（1）、（2）, circular center pillar（3）And base plate（4）Composition.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
Description
Technical field
It is used for proximity switch TX magnetic cores the present invention relates to a kind of magnetic core, more particularly to one kind.
Background technology
Proximity switch needs to use a kind of complex-shaped magnetic core, and this often brings blank and is difficult to compressing problem, it is necessary to using baroque special press, 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 turn into waste product when sintering, and substantially reduces product percent of pass, causes production high cost, very big waste is brought to manufacturing.In order to solve this problem, by optimizing design to core const ruction, so that magnetic core can be manufactured by high-volume low cost.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided one kind can be applied to proximity switch, 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 proximity switch TX magnetic cores, and the magnetic core is by 3 font side legs（1）、（2）, circular center pillar（3）And base plate（4）Composition.The magnetic core is formed by Ferrite Material sintering, or is formed by metal soft magnetic powder compacting.
The beneficial effects of the invention are 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.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is single magnetic core stereogram.
Specific embodiment
One kind is used for proximity switch TX magnetic cores, and the magnetic core is by 3 font side legs（1）、（2）, circular center pillar（3）And base plate（4）Composition.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.
