Technical field
This utility model relates to inducer field, and espespecially a kind of mixed metal powder core combination flat wire is vertical around inductance.
Background technology
In prior art, ring-shaped inductors generally comprises toroidal core and the insulated conductor coil being wound on toroidal core.In order to change the power of ring-shaped inductors, often through changing the line footpath of insulated conductor or changing the number of turns that insulated conductor is wound around.When magnet ring radius is fixed, to increase the power of ring-shaped inductors, the insulated conductor using line footpath bigger is then needed to be wound on magnet ring or increase the number of turns that insulated conductor is wound around, both modes are used to make ring-shaped inductors the most crowded, and the method using flat-wise coil, flat more around the number of plies, product turn-to-turn capacitance is big, and work long hours poor radiation.Additionally, existing inductance is all to use pure sendust core or pure iron silicon magnetic core, use the DC BIAS curve difference of pure sendust core, and use the loss of pure iron silicon magnetic core big.
Utility model content
For solving the problems referred to above, this utility model provides a kind of beneficially heat radiation, EMC is effective, DC BIAS curve is good, it is vertical around inductance that low mixed metal powder core combination flat wire is lost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mixed metal powder core combination flat wire is vertical around inductance, including magnetic core, flatwise coil, described magnetic core includes sendust core, ferrum silicon magnetic core, and described ferrum silicon magnetic core is alternate with sendust core is connected cyclization, and fixed by gluing, described flatwise coil is circumferentially positioned on magnetic core, and described flatwise coil anulospiral ending draws the terminals for connecting circuit board, is provided with insulating paper skeleton between described flatwise coil and magnetic core.
Specifically, described sendust core quantity is 2 pieces, and described ferrum silicon magnetic core quantity is 2 pieces.
Specifically, described sendust core, ferrum silicon magnetic core are rectangular parallelepiped core.
Specifically, described flatwise coil is vertical around ferrum silicon magnetic core winding displacement one layer.
Specifically, described flatwise coil is enamel covered wire, enamel insulated aluminium wire or alloy enamel-covered wire.
The beneficial effects of the utility model are: this utility model avoids the pure sendust core DC BIAS curve difference of use, and use the shortcoming that pure iron silicon core loss is big, inductance uses sendust core to be used in mixed way with ferrum silicon magnetic core, it is combined into toroidal core so that inductance has that DC BIAS curve is good, low advantage is lost；Additionally, flatwise coil uses the vertical coiling of monolayer, not only inductance turn-to-turn capacitance is little, EMC is effective, and coil radiating effect also more preferably, be lost low, reduce product temperature rise, turn-to-turn short circuit will not occur so that be more stable during work, efficiency is high.

Detailed description of the invention
Refer to shown in Fig. 1-2, this utility model is vertical around inductance about a kind of mixed metal powder core combination flat wire, including magnetic core 1, flatwise coil 2, described magnetic core 1 includes sendust core 11, ferrum silicon magnetic core 12, and described ferrum silicon magnetic core 12 is alternate with sendust core 11 is connected cyclization, and fixed by gluing, described flatwise coil 12 is circumferentially positioned on magnetic core 1, and described flatwise coil 2 anulospiral ending draws the terminals 3 for connecting circuit board, is provided with insulating paper skeleton between described flatwise coil 2 and magnetic core 1.
Compared with prior art, this utility model avoids the pure sendust core 11DC BIAS curve difference of use, and use pure iron silicon magnetic core 12 that big shortcoming is lost, inductance uses sendust core 11 use mixed with ferrum silicon magnetic core 12, it is combined into toroidal core 1 so that inductance has that DC BIAS curve is good, low advantage is lost.
Specifically, described sendust core 11 quantity is 2 pieces, and described ferrum silicon magnetic core 12 quantity is 2 pieces.
Specifically, described sendust core 11, ferrum silicon magnetic core 12 are rectangular parallelepiped core 1.
Using such scheme, magnetic core 1 uses that sendust core 11 is mixed with ferrum silicon magnetic core 12 to be used, and is combined into toroidal core 1 so that inductance has that DC BIAS curve is good, low advantage is lost.
Specifically, described flatwise coil 2 is vertical around ferrum silicon magnetic core 12 winding displacement one layer.
Using such scheme, flatwise coil 2 uses the vertical coiling of monolayer, and not only inductance turn-to-turn capacitance is little, EMC is effective, and coil radiating effect also more preferably, be lost low, reduce product temperature rise, turn-to-turn short circuit will not occur so that be more stable during work, efficiency is high.
