Description

A kind of miniature magnetic bead inductance
Technical field
the utility model relates to inductors technique field, particularly relates to a kind of miniature magnetic bead inductance.
Background technology
Bead inductor, as one of key element in electronic equipment, is a kind of filter inductance that application development is very fast in recent years, it is cheap, easy-to-use, filter away high frequency noise effect shows.Ferrite Bead not only can damage and littlely also can be widely used in other circuit by magnetic core in high frequency.Particularly in digital circuit, because pulse signal contains the very high high order harmonic component of frequency, be also the main contributor of circuit high frequency radiation, so the effect of Bead can be played in this occasion.Its volume becomes less, weight becomes gentlier, the lifting of performance is the direction that this technical field personnel lay siege to always;
The Bead inductor of current market, its structure is single, and be generally a circle inductance, inductance is less, and filter capacity is poor, and Bead thinning galvanization loss height of running business into particular one easily is entered saturated, does not cater to the development of current express network information age.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of miniature magnetic bead inductance, make simple, be convenient to automated production, boostfiltering inductance AC signal is converted into heat energy ability, improves inductance value and strengthen logical big current magnetic saturation ability simultaneously under thin thinning prerequisite.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of miniature magnetic bead inductance, comprise magnetic core, be provided with integral type coil-conductor in described magnetic core, this integral type coil-conductor has signal pins, and this signal pins is exposed outside magnetic core.
Described magnetic core comprises the first magnetic core and the second magnetic core, and the first magnetic core is provided with magnetic core center pillar and magnetic core groove, and integral type coil-conductor is contained in this magnetic core groove, and the second magnetic core is fitted on the first magnetic core and is clamped between this first magnetic core and second magnetic core by integral type coil.
The side of described first magnetic core is provided with magnetic core side column.
On described first magnetic core, the dual-side parallel with the bearing of trend of magnetic core groove is provided with magnetic core side column.
Described magnetic core side column, magnetic core center pillar and magnetic core groove are arranged in parallel.
The height of described magnetic core side column is consistent with the height of magnetic core center pillar.
Described integral type coil-conductor comprises some connectors, has interval and be interconnected between adjacent connector.
The quantity of described connector is consistent with the quantity of magnetic core groove, and connector is inlaid in magnetic core groove.
Described each connector be arranged in parallel.
Described integral type coil-conductor is copper conductors.
The utility model takes integral type coil-conductor, coil-conductor is inlaid in magnetic core groove that magnetic core is arranged, ensure installation capability, realize the small-sized thin thinning of filter inductance, boostfiltering inductance AC signal is converted into heat energy ability, improves inductance value and strengthen logical big current magnetic saturation ability simultaneously under thin thinning prerequisite.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model decomposing state structural representation;
Accompanying drawing 2 is the utility model perspective view.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of miniature magnetic bead (Beed) inductance, and comprise magnetic core, be provided with integral type coil-conductor 30 in described magnetic core, this integral type coil-conductor 30 has signal pins, and this signal pins is exposed outside magnetic core.Magnetic core comprises the first magnetic core 10 and the second magnetic core 20, first magnetic core 10 is provided with magnetic core center pillar and magnetic core groove, integral type coil-conductor is contained in this magnetic core groove, and the second magnetic core 20 is fitted on the first magnetic core and is clamped between this first magnetic core and second magnetic core by integral type coil.In the present embodiment, be provided with three magnetic core grooves altogether, be respectively magnetic core groove 11, magnetic core groove 13 and magnetic core groove 15, two magnetic core center pillars, be respectively magnetic core center pillar 12 and magnetic core center pillar 14, magnetic core center pillar 12 is located between magnetic core groove 11 and magnetic core groove 13, and magnetic core center pillar 14 is located between magnetic core groove 13 and magnetic core groove 15, and magnetic core groove and magnetic core center pillar are all designed to square.Dual-side parallel with the bearing of trend of magnetic core groove on the first magnetic core is also provided with magnetic core side column.Magnetic core side column, magnetic core center pillar and magnetic core groove are arranged in parallel.In order to optimized design, the height of magnetic core side column is consistent with the height of magnetic core center pillar, and the second magnetic core can be installed with the first magnetic core stably.
Integral type coil-conductor 30 comprises some connectors, has interval and be interconnected between adjacent connector, and each connector be arranged in parallel, thus forms multi-turn conductor.The quantity of connector is consistent with the quantity of magnetic core groove, and connector is inlaid in magnetic core groove.In addition, integral type coil is preferably copper conductors.In the present embodiment, have three connectors, be respectively connector 31, connector 32 and connector 33, signal pins has two, is respectively signal pins 34 and signal pins 35.Copper conductors 30 forms connector 31 by signal pins 34 starting point by cutting side by side, connector 32, connector 33 eventually pass through signal pins 35 and enclose or multi-turn Ampereconductors for terminal forms two.Copper conductors is set at the bottom of similar bilateral UU type foil conductor resistance rate, logical big current, perfect heat-dissipating, is the two circle of a plane coiling or multi-turn conductor, installs with magnetic core slot fit, effective improving product anti-saturation inductance value.
