Abstract

The utility model is a low-inductance single-coil coil structure with large energy storage. The utility model comprises a magnet, a conductor and a gap. The magnet is composed of an upper magnet and a lower magnet; wherein, the lower magnet can be provided with a trough and the proportion of the width (height) of the trough and the width (height) of the whole magnet is lower than one third. The conductor can be arranged through the trough and the two sides of the conductor are bent downwards to be terminals. The gap is arranged between the upper magnet and the lower magnet. By use of the proportion of the width (height) of the trough and the width (height) of the whole magnet, which is lower than one third, the utility model shortens the magnet circuit path caused by inductance. At the two sides of the trough, the utility model increases the sectional area, through which the magnetic filed lines provided by the magnets flow, thereby promoting inductance. Therefore, under the condition of inductance of the same inductance value, the gap of the utility model can be larger than the existing gap, thereby being convenient for processing production, having good saturated energy storage effect and good magnetic saturation and forming a low-inductance single-coil coil structure with large energy storage.

Description

The big energy storage individual pen formula loop construction of low sense

Technical field

The utility model relates to a kind of induction structure.

Background technology

As shown in Figure 1, be general existing induction structure 1, it comprises: a magnet 11; One lead 12, described lead 12 windings are on magnet 11;

Please consulting shown in Figure 2ly again, is another induction structure 2, and it comprises: a magnet 21, and described magnet 21 offers gap 24; One lead 22, described lead 22 windings are on magnet 21;

Please consult the schematic diagram that Fig. 3 is the inductance BH curve again, wherein, curve 13 is induction structure 1 its BH curve of representative graph 1, and curve 23 is induction structure 2 its BH curve of representative graph 2, BMAX then represents the peakflux density of described magnet 11,21, mild than the BH curve of induction structure 1 by induction structure 2 its BH curve that offer gap 24 among Fig. 3 as can be known again, the formula by the magnetic field intensity (H) of inductance is again:

$H=\frac{\mathrm{NI}}{1}$

H: the intensity N of power plant: the number of turn 1: magnet length I: electric current

Its electric current (I) was than induction structure 1 big (because of N, 1 is a definite value) when described as can be known induction structure 2 will arrive magnetic saturation, again by the energy storage formula of inductance:

$W=\frac{1}{2}{\mathrm{LI}}^2$

Can learn, when induction structure 2 with induction structure 1 during all at BMAX, the electric current of induction structure 2 (I) is big than induction structure 1, so induction structure 2 its saturated energy storage effects are good than induction structure 1, therefore, all are provided with gap 24 usually at the big energy storage inductor of described low sense in practical application, and from the above if gap 24 is big more, the BH curve of inductance will be mild more, so electric current (I) is big more, then saturated energy storage (W) effect of inductance is good more;

Please consulting shown in Figure 4ly again, is " the big energy storage inductor of the low sense of SMD " at present commonly used on the market, and it comprises: a magnet 3, described magnet 3 are provided with slotted eye 31 and gap 32, and described slotted eye 31 is wide corresponding with terminal plate or be slightly larger than; One terminal plate 33, described terminal plate 33 are conductors of a flat, and described terminal plate 33 is arranged in the slotted eye 31;

But above-mentioned existing " SMD low sense big energy storage inductor " and increases the energy storage effect of described inductance though can rely on magnet 3 be provided with gap 32; But, described " the big energy storage inductor of the low sense of SMD " is in order to be SMD (surface adhering technology), and employing terminal plate 33, thereby make magnet 3 its slotted eyes 31 need offer the size of a larger area hole with mating terminals sheet 33, and then cause described inductance when producing magnetic circuit path 34, described magnetic circuit path 34 is longer, makes that also magnet 3 its sectional areas of terminal plate 33 left and right sides directions are less simultaneously;

By inductance (L) formula be again:

$L=\frac{\mathrm{N\Φ}}{1}$

L: inductance value N: number of turn Φ: magnetic figure 1: the length of magnetic path

(Φ) is with magnetic figure:

Φ＝B·A

B: magnetic flux density Φ: magnetic figure A: the sectional area that magnetic figure vertically passes through

Can learn, its magnetic circuit path 34 of the big energy storage inductor of the low sense of described SMD is long less with sectional area (A), and then cause itself inductance value of the big energy storage inductor of the low sense of described SMD lower, the inductance value of cause itself is lower, just must dwindle machining gap 32, otherwise the inductance value of inductance will not be inconsistent the market demand, and then cause the inconvenience of processing, and gap 32 less saturated energy storage (W) effects by aforementioned its inductance as can be known are also relatively poor;

Moreover if under the constant situation of magnetic figure (Φ), if magnet 3 its sectional areas (A) are less, then the magnetic flux density that it produced (B) is high more, and therefore, its magnetic saturation effect of the big energy storage inductor of the low sense of described SMD is also relatively poor; Therefore, how disappearance such as above-mentioned is forgone, and provide a kind of and offer big gap, shortened magnetic circuit simultaneously, increasing section is long-pending with convenient processing, to reach good saturated energy storage effect and magnetic saturation effect, be the place of the technical difficulties of this case utility model institute desire solution.
