Definitions
- the present invention relates to a method for producing a winding, in particular for a winding for high voltage ignition coil circuit.
- the voltage across the secondary can reach several tens of thousands of volts, various arrangements have already been proposed in order to limit the risks of a spark between two turns of this winding.
- a bobbin comprising a tubular core winding and a plurality of fins perpendicular to the axis of the core.
- the fins define compartments between them winding annulars whose core forms the bottom, and comprise each a passage to allow the wire of the secondary winding to move from one compartment to the adjacent compartments.
- EP-A-0 375 502 thus provides for isolation compartments between the winding compartments of so as to increase the distance between the turns of two successive winding compartments. This provision presents however the disadvantage of increasing the axial dimension of the bobbin secondary.
- a winding has also been proposed, in particular for a circuit high voltage ignition coil formed, at least in part, of plies of substantially frustoconical threads placed side by side continuously.
- Each sheet can be formed of a plurality of turns in series from at least one turn of smaller diameter to at least a turn of larger diameter and vice versa.
- At least one tablecloth can be linked by its smallest turn diameter at the turn of smaller diameter of one of the sheets adjacent, and by its turn of larger diameter to the turn of more large diameter of the other adjacent tablecloth.
- the invention aims to provide such a method which can be easily automated.
- the invention relates to a method according to the claim 1.
- all of the steps b) are driven over the same length.
- FIG. 1 in axial section, one end 1 of a high voltage winding coil of an ignition coil.
- This bobbin has a central cylindrical part 2 and at least one tapered end portion 3.
- the frustoconical part 3 is connected to the cylindrical part 2 by its base of small diameter.
- Wire 4 begins to be wound at the fitting location between parts 2 and 3. The winding continues on part 3 towards outside the coil both axially and radially. We thus forms a first ply of wires 5, frustoconical, applied to part 3 of the bobbin.
- the winding continues radially and axially inward of the bobbin to form a second ply 6, frustoconical, resting on ply 5.
- the layers 5, 6, 7 ... are placed side by side in the others in series.
- the sheet 6 is connected to the sheet 5 which la precedes by the larger diameter turns of each of these plies.
- the ply 6 is connected to the ply 7 which follows it. by the two smaller diameter turns of each of these two plies.
- Figure 2 shows a winding mode which avoids the use of a bobbin with a frustoconical end.
- a wire winding starts here at one end axial of the hub 8, in contact with the flange 9.
- a first layer of base 10 is wound from the flange 9 to the center of the bobbin on a length L.
- the winding continues in the opposite direction, that is to say towards the flange 9, over a length less than L, ie Ld 1 , to form a second layer which is interrupted before the flange 9.
- the winding resumes in the first direction, namely, towards the center of the winder to form over a length greater than Ld 1 a third winding layer.
- This third layer, of length Ld 1 + d 2 therefore extends in the direction of the central part of the bobbin beyond the base layer and the first layer, and on this part of length d2 is therefore in contact of the hub 10 of the bobbin.
- each odd layer being rolled up in FIG. 2 from right to left, moving away from the flange 9 until it exceeds the previous layers by a length d 2 , and each even layer being rolled up from left to right in approaching the flange 9, and being stopped at a distance d 1 from the start of the previous layer.
