Abstract
The invention discloses a cross clock type circular common-mode inductor winding method. Windings with the same number of turns are wound around the two sides of an amorphous or ferrite or other circular magnetic core; a certain length is reserved at one end of one of the windings, one side of the winding is wound from the six o'clock position to the twelve o'clock position for bottoming, then wound back to the nine o'clock position and then wound back to the twelve o'clock position from the nine o'clock position, and the other side of the winding is wound from the six o'clock position to the nine o'clock position and wound back to the six o'clock position; the same length is reserved at one end of the other winding, one side of the winding is wound from the six o'clock position to the twelve o'clock position for bottoming, then wound back to the three o'clock position and wound to the twelve o'clock position from the three o'clock position, and the other side of the winding is wound from the six o'clock position to the three o'clock position and then wound back to the six o'clock position. The winding method can effectively reduce the bounce phenomenon of the front several turns, and not only can meet the requirements of electromagnetic interference under high frequency, but also greatly improves the labor productivity.
Description
Technical field
The invention belongs to annular common mode inductance method for winding, particularly the cross clock-type method for winding of annular common mode inductance.
Background technology
Method for winding is extremely important to control electromagnetic interference.In current annular common mode inductance, there are two kinds of methods: the first is that two windings respectively from head rearwardly coiling, then turn back to head, are also called Z-shaped winding structure at the both sides of FERRITE CORE difference coiling two windings.Although this winding structure winding is simple, cannot be tested by electromagnetic interference when high frequency.The second is that two windings respectively from centre to both sides coiling, then unroll to centre, are also called butterfly winding structure at the both sides of FERRITE CORE difference coiling two windings.This kind of winding adopts more a kind of winding in current common mode inductance, can be tested when high frequency by electromagnetic interference.But in actual winding process because be from centre around, practical operation is got up more difficult, and former circle easily has a rebound, and because from centre around, the number of turns easily miscounts.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned existing method for winding existence, a kind of cross clock-type method for winding of annular common mode inductance is provided, effectively can reduce the rebound phenomena of former circle, when this kind of winding not only can meet high frequency, electromagnetic interference requirement, also substantially increases labor productivity.
For effectively solving the problems of the technologies described above, the technical scheme that the present invention takes is as follows: a kind of cross clock-type method for winding of annular common mode inductance, at the winding of the identical number of turn of the both sides of the toroidal core such as amorphous or ferrite difference coiling, one group of winding one end reserves certain length, from 6 around to 12 shop fixtures, unroll again to 9 points, then unroll to 12 points from 9; Another side around to 9 points, then unrolls to 6 points from 6; Other one group of winding one end reserves same length, from 6 around to 12 shop fixtures, then unrolls to 3 points, then from 3 around to 12 points; In addition while from 6 around to 3 points, then unroll to 6 points.
Further, the winding that encloses of coiling 27 respectively on the both sides of amorphous or ferrite toroidal magnetic core, one group of winding one end reserves certain length, from 6 o'clock to 12 o'clock around 13 circle shop fixtures, then to 95 circles that unroll, then from 9 o'clock to 12 o'clock 2 circles that unroll; Another side enclosed from 6 o'clock to 9 o'clock around 5, then from 9 o'clock to 6 o'clock 2 circles that unroll.Other one group of winding one end reserves same length, from 6 o'clock to 12 o'clock around 13 circle shop fixtures, then to 35 circles that unroll, then from 3 o'clock to 12 o'clock 2 circles that unroll; In addition while from 6 o'clock to 3 o'clock around 5 circles, then from 3 o'clock to 6 o'clock 2 circles that unroll.
Advantageous effect of the present invention is: the cross clock-type of this annular common mode inductance is simple and convenient around existing method, has stopped the rebound phenomena of former circle; The good number of the ground floor shop fixtures number of turns, avoids the impact that the number of turns is brought electric property around mistake; Adopt method for winding of the present invention to carry out coiling, labor productivity improves whole one times.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, for 27 circles, the specific embodiment of the present invention is described further.The winding that encloses of coiling 27 respectively on the both sides of amorphous or ferrite toroidal magnetic core, one group of winding one end reserves certain length, from 6 o'clock to 12 o'clock around 13 circle shop fixtures, then to 95 circles that unroll, then from 9 o'clock to 12 o'clock 2 circles that unroll; Another side enclosed from 6 o'clock to 9 o'clock around 5, then from 9 o'clock to 6 o'clock 2 circles that unroll.Other one group of winding one end reserves same length, from 6 o'clock to 12 o'clock around 13 circle shop fixtures, then to 35 circles that unroll, then from 3 o'clock to 12 o'clock 2 circles that unroll; In addition while from 6 o'clock to 3 o'clock around 5 circles, then from 3 o'clock to 6 o'clock 2 circles that unroll.The difference of reserved length and the number of turns of unrolling, magnetic core internal-and external diameter and terminate to hold the length exceeding magnetic core relevant.The specific embodiment of the present invention encloses for 27 the explanation carried out, and specifically around which floor determines according to the concrete number of turns around a few circle.
