Description

A kind of UUI type inductor
Technical field
The utility model relates to inductor, relates in particular to a kind of UUI type inductor, 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 coiler part of air gap lose the transformation of " electricity-magnetic ", the AL value of magnetic core reduces, 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.
Summary of the invention
The purpose of the utility model provides a kind ofly controls the magnetic air gap amount with skeleton, and the UUI type inductor that can significantly practice thrift copper material and improve quality factor.
The technical scheme of the utility model is achieved in that
A kind of UUI type inductor is characterized in that, comprises UUI type magnetic core, skeleton and coil; Said UUI type magnetic core is made up of an I font center pillar magnet and two U font side column magnets; Said skeleton comprises that the coil of a band hollow hole twines axle and is positioned at two coil baffle plates that twine the axle two ends; On the lateral surface of two coil baffle plates, be respectively equipped with two side column magnet slots; Two magnet slots are positioned at the hollow hole both sides; And be connected with hollow hole and coil baffle edge, the width of magnet slot is greater than the width of hollow hole, and four support pads that between hollow hole and magnet slot, form symmetry are prominent; On shaped framework coil winding axle, twine coil is set; I font magnet is inserted in the hollow hole; Two U font side column magnets are inserted respectively in the side column magnet slot, two sides that the export-oriented end face of two U font side column magnet folding arms is affixed to I font center pillar magnet form closed magnetic loop again; Because the prominent support pad of support pad on the skeleton, between the export-oriented end face of the side of I font center pillar magnet and U font side column magnet folding arm, formed magnetic air gap.
The beneficial effect of the utility model is:
1, the utility model is compared with the inductance component of Traditional use EE type or EI type magnetic core, because the utility model has changed single magnetic air gap structure of traditional devices, has adopted more reasonably magnetic structure of magnetic air gap position; Magnetic pressure is evenly distributed; Dispersing flux reduces, and dispersing flux reduces the influence of coil, and the induction factor of magnetic core increases; Thereby the minimizing coil turn has been saved copper material.
2, the utility model inductance component air gap has reduced the influence of dispersing flux effectively away from the line bag, has reduced the power loss of device, not only saves energy but also prolong useful life of product.
3, the utility model is controlled magnetic air gap with skeleton, when having reduced UUI type inductor assembler effectively, has reduced the process and assemble cost.
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Embodiment
Embodiment 1
A kind of UUI type inductor embodiment referring to Fig. 1~Fig. 3, is characterized in that, comprises UUI type magnetic core 1, skeleton 2 and coil 3; Said UUI type magnetic core is made up of an I font center pillar magnet 1-1 and two U font side column magnet 1-2; Said skeleton comprises that the coil of a band hollow hole 2-3 twines axle 2-1 and is positioned at two coil baffle plate 2-2 that twine the axle two ends; On the lateral surface of two coil baffle plates, be respectively equipped with two side column magnet slot 2-2-1; Two magnet slots are positioned at the hollow hole both sides; And be connected with hollow hole and coil baffle edge, the width of magnet slot forms four prominent 2-2-2 of support pad of symmetry greater than the width of hollow hole between hollow hole and magnet slot; On shaped framework coil winding axle, twine coil is set; I font magnet is inserted in the hollow hole; Two U font side column magnets are inserted respectively in the side column magnet slot, two sides that the export-oriented end face of two U font side column magnet folding arms is affixed to I font center pillar magnet form closed magnetic loop again; Because the prominent support pad of support pad on the skeleton, between the export-oriented end face of the side of I font center pillar magnet and U font side column magnet folding arm, formed magnetic air gap.
In the present embodiment, said U font side column magnet is provided with a straight-arm 1-2-1, is provided with two folding arm 1-2-2 at the straight-arm two ends, and two folding arms are positioned at the same side of straight-arm, and integral body is the U font.On skeleton hollow hole and the corresponding hole wall of magnet slot, be provided with the spacing muscle 2-3-1 of center pillar magnet.
When assembling the utility model, should make I font center pillar magnet be positioned at the center of hollow hole.In order to reach this point, should reduce the dimensional discrepancy of the spacing muscle width of center pillar magnet of I font center pillar magnet and skeleton as far as possible, when dimensional discrepancy is big, also solve through the method for grinding two sides of I font center pillar magnet.Want the prominent dimensional discrepancy of support pad on the strict control skeleton,, reduce the deviation of the utility model inductance value with control magnetic air gap amount.Closely wrap up with insulating tape in the outside at the closed magnetic loop magnet, makes UUI type magnetic core and skeleton combine closely, firmly.
Embodiment 2
A kind of UUI type inductor Another Application embodiment; Referring to embodiment one, be with the difference of embodiment one, do not establish the spacing muscle of center pillar magnet on the present embodiment skeleton hollow hole wall; Be wavy with the corresponding hole wall of magnet slot, also can reach the effect of restriction I font center pillar magnet positions.
