Abstract
The utility model relates to an inducer, in particular to an inducer for a PC (personal computer) power supply, which comprises a wire frame, wherein a middle hole is arranged on the center of the wire frame; a coil is wound in a wire slot on the periphery of the middle hole; the difference is that the inducer also comprises two magnetic cores which are arranged oppositely; stand columns or side walls are arranged on the peripheries of the inducer; middle columns are arranged on the middle parts; the wire frame is sleeved on the middle columns; when the two magnetic cores are opposite, a clearance is leaved between the two middle columns; and a step wall is arranged on the end face of the middle column of at least one of the two magnetic cores. The making process of the coil of the inducer is simpler than the making process of the circular inducer. The coil can be mechanically wound, thereby lowering the manufacturing cost, increasing the efficiency of the power supply and efficiently replacing the traditional circular inducer.
Description
Technical field
The utility model relates to a kind of inductor, particularly a kind of inductor that is used for PC power source.
Background technology
Inductor is used very extensive as a kind of basic electronic component.Wherein, be equipped with inductor in the PC power source before and after transformer, input inductance before and after the transformer and outputting inductance often all adopt annular inductance as shown in Figure 1, mainly include toroidal core 1, are wound with plain conductor 2 on it.This toroidal inductor shows higher inductance when little electric current, guaranteed that electric current is continuous, and reduces to lower inductance when big electric current.This toroidal inductor adopts the manual type coiling to form usually, and not only human cost height, and efficient is not high.
Summary of the invention
At the deficiency of above-mentioned existing product, the utility model provides a kind of novel branch body structure inductor, can be used for PC power source, as the input and output inductance.
For realizing above-mentioned technical purpose, the inductor that is used for PC power source that the utility model provides, adopt following technical scheme:
A kind of inductor that is used for PC power source includes coil holder, and coil holder central authorities are provided with interstitial hole, is wound with coil in the wire casing of this interstitial hole periphery; Its difference is, also includes two magnetic cores establishing relatively, and described magnetic core periphery is provided with column or sidewall, and the centre is provided with center pillar, and described coil holder is set on the center pillar; When two magnetic cores are relative, intercolumniation leaves the gap in two.Insert the interstitial hole of coil holder when its center pillar after, the center pillar of magnetic core cooperates with the column in the outside or sidewall, will form a magnetic loop at the wire casing periphery of coil holder.
Further, described center pillar height has at least a slice to be lower than outer shroud column or sidewall height, after two magnetic core assemblings, forms air gap between the center pillar.
As improvement of the technical scheme, described two magnetic cores have at least the center pillar end face of a slice to be provided with step surface; When described two magnetic cores were relative, intercolumniation formed overlap span in two.
Further, the center pillar end face of described two magnetic cores is provided with the step surface that cooperatively interacts.
Further, described center pillar is circular or square.
Further, described inductor is vertical or is horizontal.
Adopt the inductor of this segmentation gap structure, under little current status, inductance value is higher, thereby guarantees that electric current is continuous; When big electric current; Inductance is lower.Adopt the utility model can effectively substitute traditional annular inductance, and inductance efficient also have lifting.Its coil manufacture technology, more annular inductance is simple, and can adopt mechanical coiling, has not only reduced production cost, and has improved the efficient of power supply again.

Embodiment
Understanding and realization the utility model for the ease of persons skilled in the art are further described embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 2 is a preferred embodiment of the present utility model, is a split type inductor.It comprises the two large divisions: one is coil holder 2, and coil holder central authorities are provided with circular interstitial hole 21, but in the wire casing 22 of this interstitial hole periphery winding around; And the coil holder below is provided with outstanding wire holder 23,24; Another part is two symmetrical magnetic cores 1, but is provided with a suit coil holder circular center pillar 11 thereon in the middle of magnetic core 1, and the end face of circular center pillar 11 is provided with step surface S1, the S2 (not indicating) that cooperatively interacts; When both were relative, intercolumniation formed overlap span in two; The width of described segmentation air gap and the degree of depth can be adjusted according to actual operating position.Certainly, also can only offer step surface on a center pillar end face therein.And center pillar also can be square or other shape.Wherein, coil can be single group, also can be many groups, and many groups can be used as transformer and use.
Be provided with a ring-side wall 12 at magnetic core 1 periphery, 12 of center pillar 11 and ring-side walls can ccontaining coil holder 2 and coils 22, offer opening 13 in ring-side wall 12 bottoms, and the wire holder 23 of coil holder 2 belows can be protruding from opening part 13.
This embodiment is a vertical transducer, and two jump rings 3 can be fixed therein coil holder 2 with two magnetic cores 1 by the clamping assembling.Shown in Figure 3 is the decomposition texture schematic diagram of another embodiment of the present utility model, is a kind of horizontal inductor.
The utility model is under little current status, and inductance value is higher, meets the underloading characteristic; And when big electric current, inductance is lower.Adopt the utility model can effectively substitute traditional annular inductance and be used for, as inputing or outputing inductance as PC power source.Certainly, also can be used for other occasion, and be not limited only to input and output inductance as PC power source.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection range of the present utility model.
