Abstract
The utility model discloses a novel choke coil powdered inductor, which comprises a choke coil with two wiring terminals. Metal magnetic powder is wrapped on the outer circumference of the choke coil and is in a three-dimensional geometrical shape, the two wiring terminals are respectively arranged at axial symmetrical positions on the metal magnetic powder. Since the metal magnetic powder is wrapped on the outer circumference of the choke coil and is in a three-dimensional geometrical shape while the two wiring terminals are respectively arranged at the axial symmetrical positions on the metal magnetic powder, the novel choke coil powdered inductor is simple in structure, smart in conception, beautiful and elegant in appearance, fine in electric performance, small in volume, small in magnetic leakage and magnetic interference, low in vortex loss and low in temperature rise, can be used under wide frequencies between dozens of Hz to 30 MHz, is strong in magnetic force line loop, finely behaves in saturation current, has the characteristics of fine resistance to alternating current-direct current superimposition, conforms to ROHS commands, and is suitable for extensive popularization and use.
Description
Technical field
The utility model relates to a kind of choking-winding powder pressure type inductance, especially a kind of big electric current, low magnetic loss, the little choking-winding powder pressure type inductance of internal resistance.
Background technology
At present, the enterprise of domestic production inductance is many, but because inductance kind variation, most of enterprises produce common choking-winding, and fewer for the manufacturing enterprise of paster large-current electric sense, and technology is relatively backward, production capacity does not catch up with demand, it adopts the traditional endless iron core to make the technology of inductance and makes the good inductance poor electrical performance of manufacturing easily, and volume is big, occurs the shortcoming of phenomenons such as magnetic leakage magnetic disturbance and eddy current loss are big easily.
The utility model content
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple in structure, is skillfully constructed, and is attractive in appearance proper, good electrical property, and volume is little, and the magnetic leakage magnetic disturbance is little, and eddy current loss is little, the integrally-forming compacting formula inductance that temperature rise is low.
The utility model can be achieved through the following technical solutions:
The utility model discloses a kind of novel choking-winding powder pressure type inductance, it comprises the coil windings that is coated by a metal body, coil windings is the choking-winding with two binding posts, described coil windings periphery is coated with the metallic magnetic powder, this choking-winding powder pressure type inductance adopts circular copper wire to make coil, leading foot flattened or adopts choking-winding with exit means of spot welds line terminals, described coil windings periphery is coated with the metallic magnetic powder, through realizing frequently closing inductance after the encapsulation compacting, this metallic magnetic powder is the solid geometry shape, leading foot or two binding posts are located at respectively on the both sides of metallic magnetic powder, or are located on the axial symmetry line position of metallic magnetic powder same side.
The shape of described metallic magnetic powder can cuboid, square or other solid geometry shape structures, can produce different three-dimensional shapes to reach minimum solid space volume according to producing needs, make it to adapt to more in the circuit of fine electronic product of present main flow.
After this metallic magnetic powder adopts unleaded soft magnetic metal powder by insulation and plasticity processing again by the processing mold disposal pressed moulding, and make the medium position of choking-winding in the metallic magnetic powder, and guarantee that choking-winding two binding posts are arranged on the axial symmetry line position of metallic magnetic powder same side, this side preferably should be the bottom surface of choking-winding powder pressure type inductance, and other sides of inductance can be come the parameter of the sign of printed electronics product with better identification electronic component as required.
The utility model compared with prior art has following advantage:
The utility model is coated with the metallic magnetic powder in the coil windings periphery, this metallic magnetic powder is the solid geometry shape, two binding posts of choking-winding are located at respectively on the axial symmetry line position of metallic magnetic powder, it is simple in structure, be skillfully constructed, attractive in appearance proper, good electrical property, volume is little, the magnetic leakage magnetic disturbance is little, and eddy current loss is little, and temperature rise is low, can to the broadband between 30 megahertzes, use at tens hertz, its flux loop is strong, and good performance is arranged on saturation current, has the good superimposed characteristics of anti-the alternating current-direct current, meet the ROHS instruction, be fit to generally promote the use of.
