Definitions

  • the known previous structures that provide shielding against high tension concentration effects have employed structure such that the shielding layers are applied in an electrically floating manner which fails to obtain the dual function quality that is obtained with structure according to this invention.
  • the invention concerns high voltage induction machinery. Specifically it deals with the combination of an improved high voltage coil that comprises a plurality of winding layers having predetermined axial dimensions. And it comprises at least .one turn of a conducting material strip that surrounds the outermost of said winding layers. The said strip covers said winding layers and forms a corona shield therefor.
  • FIG. 1 shows a schematic elevation partly in cross-section, illustrating a high voltage winding 3,394,331 Patented July 23, 1968 for a transformer or the like, in accordance with the invention.
  • a preferred embodiment according to this invention relates to the high voltage coil of transformers.
  • the transformer being one especially intended for use in internal combustion engine ignition systems.
  • core element 11 This may take various forms, but as schematically indicated by the dashed lines it could be a closed rectangular shape. In such cases the primary winding or low voltage winding (not shown) of the transformer would be located on another leg (not shown) of the core parallel to that illustrated.
  • Core member 11 is preferably constructed of magnetically permeable material, such as soft iron or the like, and as indicated in the drawings is preferably laminated in order to reduce eddy current elfects, as is standard practice for core materials.
  • a coil form 12 Surrounding the core 11 there is a coil form 12 that is constructed of insulating material.
  • the total coil of the illustrated transformer is made up by winding a conducting material wire 15 around the coil form 12 so as to form a plurality of layers 16-20 illustrated. It will be observed that these winding layers 16-20 are tapered in axial length as they progress outward from the coil form 12. This is done in order to provide a decrease in voltage per layer as the layers progress outwardly toward the outside of the coil.
  • the individual turns of the winding layers are separated by two diameter spacing (center to center) of the wire 15 as the turns are laid on. Each layer of turns is separated from the next successive layer by a thin sheet of insulating material 23. This is preferably a material such as that known by the trade name Mylar.
  • the two turns of strip 25 are electrically connected in series with the coils (wrapped in layers 1620) so as to form the last two turns of the total coil. This is accomplished in any feasible manner such as by carrying the end .of the last turn on outer layer 20 around one edge of the strip or sheet 24, as illustrated, by a short connecting wire 30. The outermost or free end of strip 25 is then connected to a terminal wire 31. The other end of the complete coil is brought out from the coil structure via a terminal wire or connecter 32, as illustrated.
  • the outermost or covering layer for the coil is preferably a triple thickness sheet 35. This is preferably constructed of the same insulating material as that employed in the inner separating sheets 23 and 24 and 26.
  • winding layers being tapered in axial length thereof as they progress outward from the axis of the coil in order to reduce the voltage per layer, and a conducting material winding comprising a strip surrounding the outermost of said winding layers,
  • said conducting material winding strip having at least two turns and being connected in series with the end of said outermost winding layer
  • said strip covering said winding layers and forming a corona shield therefor.
