Abstract
The utility model relates to a ferrite magnetic core which is an improved design for E-E type magnetic core to realize the technology of the non-frame winding manufacture, the first processing and then binding manufacture, etc. The utility model is composed of a star-shaped ferrite base component, a line-shaped ferrite base component, and an H-shaped ferrite base component. The three kinds of ferrite base components can conduct the multiple magnetic-path flexible combination. The three components forming two structures comprise two U shape and one line shape, two line shape and one H shape, and two U shape and one H shape; the four components forming two structures can be combined into three U shape and one line shape; the five components two structures can be combined into four U shape and one line shape in plane or solid way. The utility model is good for enhancing the magnetic property so as to make the integration magnetism really become a practical and valuable production technology.
Description
The utility model relates to a kind of magnetic core, relates to core structure or rather.
Make transformer, inductance etc., add magnetic core in the coil, can increase inductance value and quality factor, reduction of device volume.Existing core structure comprises the different shape made from soft magnetic materials such as metal, magnetizing mediums, ferrites, as magnetic cores such as E type, U type, jar shape, annular, cylindricality, screw-types.
At present, integrated magnetics is generally made with standard E-E type magnetic core, has the drawback that is difficult for adjustment air gap, bad coiling, is unfavorable for realizing mechanization production.
The purpose of this utility model is based on standard E-E type ferrite magnetic core, design a kind of fabricated structure magnetic core of realizing the multipath magnetic circuit combination, can carry out exoskeletal coiling and process the bonding manufacture craft in back earlier, make integrated magnetics have manufacturability, reduce leakage field simultaneously and improved magnetic characteristic etc.
Fabricated structure magnetic core of the present utility model is the combining structure of " Qian " type, " worker " type, 3 kinds of basic magnetic spares of "-" type.
Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing.
The bare bones perspective view of accompanying drawing 1 fabricated structure magnetic core
1 of accompanying drawing 2 fabricated structure magnetic core embodiment combining structure schematic diagrames
2 of accompanying drawing 3 fabricated structure magnetic core embodiment combining structure schematic diagrames

Referring to accompanying drawing 1, the basic magnetic spare of this fabricated structure magnetic core has 3 kinds, comprises " Qian " type, "-" type and " worker " type, shown among the figure 1,2,3.Bare bones is few, and simple in structure, thereby can simplify the mold design that magnetic spare is made, and helps reducing die cost.
Referring to accompanying drawing 2, with 2 " Qian " type magnetic spares 1 and 13 bonding 2 kinds of multipath magnetic circuit core structure of "-" type magnetic spare 2 combinations.Obviously, Copper Foil or copper strips can directly be wound on the magnetic spare, and needn't consider around to, then three magnetic spares are bonded together, it is very convenient to adjust air gap.
Referring to accompanying drawing 3,, also has above-mentioned advantage with 2 "-" type magnetic spares 2 and 13 bonding 2 kinds of multipath magnetic circuit core structure of " worker " type magnetic spare 3 combinations.
Referring to accompanying drawing 4,, has the as above same advantage of 2 examples with 2 " Qian " type magnetic spares 1 and 13 bonding 2 kinds of multipath magnetic circuit core structure of " worker " type magnetic spare 3 combinations.
Above-mentioned 3 kinds of 2 groups of multipath magnetic circuit core structures have and the identical magnetic structure of standard E-E type magnetic core, but air gap position difference.
Referring to accompanying drawing 5, with 3 " Qian " type magnetic spares 1 and 4 bonding 2 kinds of multipath magnetic circuit core structures of 1 "-" type magnetic spare, 2 combinations, characteristics such as also have exoskeletal coiling and the processing back is bonding earlier.
Make up 5 bonding 2 kinds of multipath magnetic circuit core structures referring to 6,4 " Qian " types of accompanying drawing magnetic spare 1 and 1 "-" type magnetic spare 2 with planar fashion.
Referring to 7,4 " Qian " types of accompanying drawing magnetic spare 1 and 1 "-" type magnetic spare 2, make up 5 bonding 2 kinds of multipath magnetic circuit core structures in three-dimensional mode.
With 3 kinds of basic magnetic spares of the present utility model, by same combinatorial principle, can also be combined into other kinds multipath magnetic circuit core structure, and all have exoskeletal coiling, bonding etc. characteristics in processing back earlier, and can select the winding configuration of coil neatly.
3 kinds of basic magnetic spares by the utility model fabricated structure magnetic core, carry out the multipath magnetic circuit textural association neatly with wherein 2 kinds, maintenance has also developed many magnetic shunt structure characteristics that classical E-E type core structure is had, not only can be used for the common high frequency transformer of coiling, inductor, also be particularly suitable for doing the design of integrated magnetics, help producing slim and ultrathin modular power source.
Owing to Copper Foil or copper strips directly can be wound on the magnetic material spare, realize exoskeletal coiling and process the bonding technology in back earlier, help reducing leakage flux, improve power source performance and magnetic characteristic, help realizing process automation, mechanization, especially to the realization of integrated magnetics in the high frequency switch power, has remarkable advantages.
The basic cordwood combining structure of magnetic spare makes the winding flexible configuration of magnetic Circuit Design, air gap adjusting and coil changeable.
This fabricated structure magnetic core cooperates Copper Foil to make the technology of winding, can make integrated magnetics really become the production technology with practical value.
