Description

The coil-winding structure of high quality factor

Technical field

The utility model relates to for the resonance coil more particularly to a kind of line of high quality factor in resonance step-up equipment Enclose winding structure.

Background technique

The typical case of resonant inductance is Tesla coil, its principle be so that inductance and capacitor is generated resonance, then this A inductance is just called resonant inductance, and capacitor is just called resonant capacitance, and current winding mode is spiral coil and plane coiling, nothing Method achievees the purpose that reduce volume, can not be applied in present electronic product.

Second, quality factor are one of the major parameters for influencing output, current air core inductor is using helically-wound and puts down Face winding, quality factor usually will not be very high, moreover, the diminution with volume can also reduce quality factor, make whole system Performance is unable to get performance.

Summary of the invention

In view of prior art situation and existing defect, the utility model provides a kind of coil-winding knot of high quality factor Structure.It the purpose is to volume requirement according to prior art, needs to accomplish in a smaller space to export high pressure, and to guarantee final The reliability of product.The utility model uses " V " type structure, makes line by improving skeleton structure, i.e., the arrangement of coiling in skeleton The higher place of voltage difference can effectively increase distance between circle, and the voltage difference between close coiling is very low.

The utility model is adopted the technical scheme that in order to achieve the above object: a kind of coil-winding of high quality factor Structure, which is characterized in that including skeleton, coiling；The skeleton is to divide slot multiple groups winding bobbin, is equipped with multiple coilings in skeleton Slot, every two winding slot form a V-shape winding slot, and every group of coiling is divided into two sections and is wound in V-shape skeleton winding slot, and every two It is connected in the outside of skeleton by coil tail head between group coiling.

Skeleton described in the utility model, which is equipped with, forms four V-shape winding slots by eight winding slots, and totally four groups of coilings are equal It is divided into two sections rotating around in four V-shape skeleton winding slots.

Coiling described in the utility model is multiply silk-covered wire.

The design principle of the utility model: at higher frequencies, the parasitic capacitance of coil is to influence coil q Principal element, therefore winding volume reduce, cause the distance between line closer, to keep capacitor bigger, influence the product of coil Prime factor, the utility model be on the basis of existing Tesla coil resonant inductance, according to the needs of coil q, Original air core coil structure is improved, the design scheme for reducing volume is taken, the parasitism of winding department is made by " V " font coiling Capacitor reduces, and reduces loss of the coil in resonance, the maximization of distance is reached to the arrangement of line, reach raising coil quality because Several purposes makes resonance step-up reach expected voltage value.

The beneficial effects of the utility model are: coiling uses " V " font coiling, reduces the stray capacitance of winding department, subtract Loss of the small coil in resonance achievees the purpose that improve coil q.Higher product are accessed in lesser volume energy Prime factor, and then reduce the volume of resonant inductance.The requirement of voltage in application apparatus, and performance can more effectively be reached It is more reliable and more stable.

Specific embodiment

Below in conjunction with drawings and examples, the utility model is described in further detail:

As shown in Figure 1 to Figure 3, the coil-winding structure of high quality factor includes skeleton 1, coiling 2；Skeleton 1 is to divide slot more Winding bobbin is organized, multiple winding slots are equipped in skeleton 1, every two winding slot forms a V-shape winding slot, and every group of coiling 2 divides It is wound in V-shape skeleton winding slot, is connected in the outside of skeleton 1 by coil tail head between every two groups of coilings 2, coiling at two sections 2 be multiply silk-covered wire.

Embodiment: skeleton 1, which is equipped with, forms four V-shape winding slots by eight winding slots, and totally four groups of coilings 2 are divided into two Section is rotating around in four V-shape skeleton winding slots, as shown in Figure 3.

It is equipped with eight skeleton winding slots in skeleton 1, forms four V-shape winding slots, coiling 2 is four groups, respectively first Root silk-covered wire 2-1, second silk-covered wire 2-2, third root silk-covered wire 2-3, the 4th silk-covered wire 2-4, four silk-covered wire length are equal For 180cm；Specific spooling step is as follows:

The first step, around first silk-covered wire 2-1, by first silk-covered wire 2-1 that a root long degree is 180cm from middle position Start, around 9 circles in first winding slot of skeleton 1, first silk-covered wire 2-1 tail head meets first terminal 1-1 in skeleton 1 On, by the other half root line of first silk-covered wire 2-1 around 9 circles, first silk-covered wire 2-1 in second winding slot of skeleton 1 Other half root line tail head connects on second terminal 1-2 of skeleton 1.
