Definitions

the invention relates to a high-voltage coil for an ignition transformer of an ignition system of an internal combustion engine according to the preamble of claim 1.
the chamber openings for connecting the individual winding chambers are arranged approximately centrally in relation to the straight sides of the hollow-cylindrical coil former. Since the ignition voltage collapses within nano or even picoseconds from approx. 15 kV to approx. 800 V, the voltage changes quickly and acts as a shock wave runs into the ignition transformer. The electrical, dynamically running fields result in high field stress in the axial direction of the secondary or high-voltage winding of the ignition transformer.
the object underlying the invention is therefore to design the high-voltage coil according to the preamble of claim 1 so that it has a high dielectric strength in the axial direction.
the embodiment shown in the drawing of the high-voltage coil according to the invention for an ignition transformer comprises a coil former which is approximately in the form of a hollow cylinder with straight sides and rounded edges.
the rounding of the edges is shown in particular in FIG. 2 in a view in the direction of the arrow BB, the rounding radius being denoted by R.
Radially protruding, circumferential separating webs 3 are provided to limit winding chambers 1, which accommodate winding groups 6 of the high-voltage winding.
the winding groups 6 each consist of a certain number of turns.
the separating webs 3 are each provided with chamber openings 4 which connect adjacent winding chambers 1 to one another.
the winding groups 6 are electrically connected to one another via a winding wire transition leading through the chamber openings 4.
the coil body can consist of a thermoplastic material and a copper wire with impregnating resin can be used as the winding wire, which wire is wound into the winding chambers 1 on the chamber bottom 5.
the chamber openings 4 are arranged at a specific point with respect to the rounded edges of the coil body.
the chamber openings 4 start in the winding direction from a point at the beginning of the rounding of a coil edge, i.e. start at the zero point of the respective circumferential radius R of the chamber base 5.
the design of the chamber openings 4 is chosen in particular so that the winding wire 2 in the area of the wire transition in the chamber openings 4 takes a tangential course on the circular arc of the rounding of the coil body with the radius A. With such a design of the chamber openings 4 within the separating webs 3 and the arrangement on the radius A, the wire is guided to the chamber bottom.
a ramp 7 is formed which extends radially and is dimensioned such that the risk of short-circuiting of turns within a winding group 6 is low.
the gap angle ⁇ and the associated radii are selected such that the parts of the separating webs 3 delimiting the chamber openings 4 overlap one another in the radial direction from the lower edge to the upper edge of the chamber openings 4.
the above-described embodiment of the high-voltage coil for an ignition transformer according to the invention can in particular be designed such that the separating webs 3 have a thickness of 1.0 to 1.7 mm in the case of a coil body made of a thermoplastic material.
the chamber openings 4 are formed obliquely to the axial direction according to FIG. 1, there is a longer insulation path in the voltage-resistant material of the coil body and a longer creep path at the interface between the material of the coil body and the casting resin with which the coil body is poured out.
the wire transition between adjacent winding chambers 1 thus has an extended creepage distance and the position of the wire transition is on one side, so that a large insulation gap is created between the windings and above the conducted winding wire.
the high-voltage coil according to the invention has the further advantage that it is insensitive to defects in the manufacturing process and the related enamelled copper wire and the impregnating resin and that the winding process is simplified.
the high-voltage coil according to the invention is characterized in particular by a longer service life when the cooking voltage winding is loaded with a spark gap, particularly at high temperatures.
