Abstract
The invention discloses a magnetic rubber inductor which comprises a ferrite drum-type magnetic core and a coil, wherein the coil is wound on the ferrite drum-type magnetic core; and a magnetic rubber layer, which is a ferrite powder resin layer, wraps up the periphery of the coil. In the magnetic rubber inductor, the magnetic rubber layer, which is made of ferrite powder resin, wraps up the periphery of the coil and a sleeveless structure inductor product is formed by using the drum-type magnetic core so that an air valve between the drum-type magnetic core and a sleeved magnetic core is omitted so as to inhibit vortex currents, thereby the alternating-current resistance is controlled to be in a smaller range.
Description
Technical field
The present invention relates to inductance, be specifically related to a kind of magnetic glue inductance.
Background technology
Inductance is widely used in mobile phone as a large amount of equipment that use Miniature Power Unit electric inductance power inductance, and HDD, DSC, DVC, portable audio equipment, notebook computer are with on the equipment such as ODD.The said equipment requires also often to be required to realize long operation keeping small size, lightweight while to inductance.Because institute's function of use is different and the increase of circuit module quantity, a plurality of high efficiency switch DC-DC transducers are actually used on equipment.That is to say that in above-mentioned mini-plant, high performance inductor is required more use.In addition, the miniaturization of equipment also requires to use the further element of having realized miniaturization, slimming.But can produce air valve and form vortex current between the magnetic core of existing inductance and the sleeve shape magnetic core.
Summary of the invention
The problem that the present invention need solve provide a kind of simple in structure, effectively suppress the magnetic glue inductance of vortex current.
To achieve these goals, the present invention designs a kind of magnetic glue inductance, comprises ferrite drum type magnetic core and coil, and described coil is around oxysome drum type magnetic core magnetic core, and the periphery of described coil is enclosed with the magnetic glue-line.
Described magnetic glue-line is the ferrite powder resin bed.
Magnetic glue inductance of the present invention is enclosed with the magnetic glue-line of ferrite powder resin by the periphery at coil, the sleeveless structure inductor product that it has used the drum type magnetic core to form, air valve between drum type magnetic core and the sleeve shape magnetic core can not produce again, vortex current has obtained inhibition, has been controlled in the small range thereby make to exchange to resist.Owing to be to use the ferrite powder resin to fix, can satisfy the required strong impact resistance of mini-plant and also obtain very big reinforcement simultaneously.
Description of drawings:
Fig. 1 is a magnetic glue induction structure schematic diagram of the present invention.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present invention is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, a kind of embodiment of magnetic glue inductance.It comprises ferrite drum type magnetic core 1 and coil 2, and described coil 2 is around oxysome drum type magnetic core magnetic core 1, and the periphery of described coil 2 is enclosed with magnetic glue-line 3.Described magnetic glue-line 3 is the ferrite powder resin bed.
Structural design of the present invention is simply unique, is got final product by two magnetic cores and circular copper wire assembling.Main material circular copper wire of the present invention and magnetic core can be general, different sense values requires and can get final product by the thickness of adjustment magnetic core and the proportioning of magnetic glue, make and need not establish, thereby reduced research and development expense and production cost, have very high superiority of effectiveness into new equipment, mould.
Foregoing is preferred embodiment of the present invention only, is not to be used to limit embodiment of the present invention, and those skilled in the art are according to design of the present invention, and appropriate adaptation of having done or modification all should be within protection scope of the present invention.
