Description
Technical field
The utility model relates to a kind of inductor, especially relates to a kind of mixed magnetic circuit inductor.
Background technology
The various coils of inductor insulated conductor coiling are called inductance.Be coiled into a circle or multiturn with wire, to produce the electronic component of certain self-inductance, normal title inductance coil or abbreviation coil, in order to increase inductance value, put forward high q-factor and reduced volume, insert magnetic core in coil of being everlasting.Common inductor is formed by coil winding.In order to increase the quality factor of inductance value and raising coil, coil can by coiling on magnetic core.The performance of material on inductor of magnetic core has important impact.In many materials, Ferrite Material is the core material comparatively commonly used, and Ferrite Material has high magnetic permeability, thus is conducive to making larger inductance.But Ferrite Material also has than being easier to this less desirable characteristic of magnetic saturation.
Utility model content
In order to overcome above technical deficiency, the utility model provides a kind of mixed magnetic circuit inductor.
The utility model provides a kind of mixed magnetic circuit inductor, it comprises magnetic core and winding, described magnetic core comprises the second magnetic core of first magnetic core of " mouth " font and the clavate between the first magnetic core, winding is wound with outside described second magnetic core, described first magnetic core adopts soft magnetic metal powder to make, it comprises the magnetic chip that at least two panels is fitted side by side, described second magnetic core adopts ferrite to make, be provided with insulation clamp between described winding and the first magnetic core, described edge insulator board is enclosed within outside winding.
Described soft magnetic metal powder is iron powder, iron aluminum silicon powder, iron silica flour or Fe-based amorphous powder.
Air gap pad is provided with between the end face of described second magnetic core and the madial wall of described first magnetic core.
Described winding is coil.
Described coil is coiled into by copper cash, copper-clad aluminum conductor or aluminum steel.
Described insulation clamp is U-shaped.
Described insulation clamp is 2, and is arranged on respectively on the upside of coil and between the first magnetic core inwall and on the downside of coil and between the first magnetic core inwall.
The beneficial effect of utility model is: have FERRITE CORE and soft magnetic metal powder magnetic core simultaneously, compared with FERRITE CORE, the magnetic core inside that soft magnetic metal powder is formed has many small air gaps, therefore magnetic core is more difficult saturated, the magnetic chip adopting at least two panels to fit side by side makes the first iron core, select according to power, reduce the manufacture difficulty of the first magnetic core, utilize insulation clamp to play effect that is fixing and insulated coil simultaneously.
Accompanying drawing explanation

Fig. 2 is lateral plan of the present utility model.
Fig. 3 is the cutaway view of A-A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of mixed magnetic circuit inductor, it comprises magnetic core and winding 4, described magnetic core comprises the second magnetic core 3 of first magnetic core 2 of " mouth " font and the clavate between the first magnetic core 2, winding 4 is wound with outside described second magnetic core 3, described first magnetic core 2 adopts soft magnetic metal powder to make, it comprises the magnetic chip 21 that at least two panels is fitted side by side, described second magnetic core 3 adopts ferrite to make, be provided with the clamp 1 that insulate between described winding 4 and the first magnetic core 2, described insulation clamp 1 is fastened in outside winding 4.
Described insulation clamp 1 is U-shaped, and described insulation clamp 1 is 2, and is arranged on respectively on the upside of winding 4 and between the first magnetic core 2 inwall and on the downside of winding 4 and between the first magnetic core 2 inwall.Utilization insulation clamp 1 reduces the signal disturbing between winding 4 and the first magnetic core 2, and can play again the effect of fixing winding 4, winding 4 is wound on the second magnetic core 3 can not be shifted.
See Fig. 2, the material of the first magnetic core 2 is soft magnetic metal powder, and permeability is less than 500H/m.The material of the second magnetic core 3 is ferrite, and permeability is greater than 1500H/m.If the first magnetic core 2 is length L in the direction (being vertical direction in figure) perpendicular to the second magnetic core 3, be width W in the direction (in figure for horizontal direction) being parallel to the second magnetic core 3, then L:W is greater than 1.2.
Air gap pad 5 is provided with between the end face of described second magnetic core 3 and the madial wall of described first magnetic core 2.
First magnetic core 2 adopts at least 2 magnetic chips 21 to arrange and is formed, utilize the feature that magnetic chip 21 volume is little, reduce the difficulty of the overall processing of the first magnetic core 2, the first magnetic core is avoided to occur damaged, affect inductance value, adopt 2 magnetic chips or multi-disc side by side magnetic chip 21 arrangement can design according to watt level, select variation.
Described soft magnetic metal powder is iron powder, iron aluminum silicon powder, iron silica flour or Fe-based amorphous powder, makes soft magnetic metal powder form the first magnetic core 2 by the mode of compacting.
Described winding 4 is coil, and described coil is coiled into by copper cash, copper-clad aluminum conductor or aluminum steel.Wherein, aluminum steel has lower price, and uses in the present invention, still meets the performance requirement of inductor.Therefore the use of aluminum steel can reduce costs further.
Embodiment should not be considered as restriction of the present utility model, any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
