Description
Technical field
The utility model relates to a kind of inductance component, relates in particular to the inductance component that a kind of magnetic air gap places line bag outside, can be widely used in the electronic circuit of various electronic apparatuss.
Background technology
Traditional inductance component generally cooperates bobbin to form around last enamelled wire by EE type magnetic core or EI type magnetic core.For preventing that the magnetic saturation phenomenon from taking place, common way is to adopt the method for grinding the magnetic core center pillar that magnetic air gap is set, and air gap is in the line bag center of inductor.Because near magnetic air gap, exist dispersing flux, dispersing flux to make near the air gap coiler part lose the transformation of " electricity-magnetic ", magnetic core
A L Value reduces, and near the coil sections the magnetic air gap only plays filling effect.The big more dispersing flux of air gap amount is just big more, and the coil of invalid filling is also just many more, and the magnetic line of force vertically passes the line bag simultaneously, causes the certain power loss.Above-mentioned reason causes device self copper resistance and copper loss to increase, and the power consumption of device is raise, waste electric energy and copper material, the useful life of reducing inductance component.
Height for the installing space of inductor is less, and traditional inductor such as EE type, EI type, EFD type etc. are adopted in demanding application scenarios such as some electromagnetic performance parameters such as quality factor, excitation angle, leakage field, and difficulty meets the demands.
Summary of the invention
The purpose of this utility model provides a kind of inductance component that can significantly save copper material, improve quality factor and increase excitation angle, reduce leakage field.
The technical solution of the utility model is achieved in that
A kind of inductance component comprises the closed magnetic loop magnetic core stack, at least one veneer magnet, skeleton and coil; It is characterized in that described closed magnetic loop magnetic core stack is made up of an I font center pillar magnet and two side column magnets; Described side column magnet is provided with a straight-arm, is provided with two folding arms on straight-arm at least; Described veneer magnet is provided with the magnetic gap groove; At least the coil that is provided with a band hollow hole on the described skeleton twines axle, is provided with two media slot in the hollow hole both sides, twines the axle two ends at coil and is provided with two coil plate washers; On the coil winding axle of skeleton, twine coil is set, the center pillar magnet is placed the hollow hole of skeleton, the air gap medium is placed the media slot of skeleton, the export-oriented end face of two side column magnet folding arms is affixed to two sides of center pillar magnet, the veneer magnet is covered in the magnetic loop magnet surface, and make magnetic gap groove span centre post magnet and air gap medium and the side column magnet formation closed magnetic loop that fits together; Because making, the support pad of air gap medium forms magnetic air gap between the export-oriented end face of center pillar magnet side and side column magnet folding arm.
Closely wrap up with insulating tape in the outside at side column magnet and veneer magnet, makes to dock close and firm between center pillar magnet, air gap medium, side column magnet and the veneer magnet.
The beneficial effects of the utility model are:
1. because magnetic air gap of the present utility model places the coil outside, make dispersing flux reduce to the influence of coil, therefore the utility model is compared with the traditional inductor that magnetic air gap is arranged on the coil middle part, can save coil turn, just under the suitable situation of performance, the use amount that can save copper material.
2. because the veneer magnet is posted in magnetic circuit of the present utility model outside, leakage flux of the present utility model is reduced; Also be because the outside has mounted the veneer magnet, can design the utility model more flat, and the side column magnet be programmable thinner, can be suitable for the application scenario that setting height(from bottom) and volume are subjected to certain restriction like this; The veneer magnet that the magnetic loop outside mounts can also improve the excitation angle of magnetic loop effectively, thereby has improved magnetic structure.
Below in conjunction with drawings and Examples the utility model is described in detail.
