Definitions

  • the present invention relates to electrical resistance elements, and is primarily concerned with an improvement in a resistor of the type comprising a linear dielectric body supporting a spiral ribbon of resistance material along its length between bands of low resistance material supported on the ends of such body and serving as the resistance element terminals.
  • Such form of resistor ordinarily comprises a circular rod of dielectric material bearing a resistance element comprising a spiral ribbon of carbon, or of tin oxide or the like.
  • a suitably coated rod is conventionally placed in a lathe and spirally grooved so that the coating material remaining is in the form of a spiral ribbon about the body between the terminal bands of low resistance material.
  • the bands of low resistance material serving as the resistor element or ribbon terminals, are extended transversely of the ribbon ends at an angle of 90 so that the current between such terminals is uniformly distributed throughout the ribbon width along its entire length, thus enabling such ribbon to withstand a current density in accordance with the ribbon width and its resistance per unit of length.
  • Fig. 1 is side elevational view of a resistor of conventional form.
  • Fig. 2 is a diagrammatic view showing the ribbon coat- 2,910,664 Patented Oct. 27, 1959 ing and terminals of a conventional form of resistor laid out in a single plane.
  • Fig. 3 is a view corresponding to Fig. 2 when modified in accordance with the invention.
  • Fig. 4 is a view, similar to Fig. 1, of a complete resistor embodying the invention.
  • the dielectric rod 11 bears low resistance metal bands or terminals 12 and 13 at its ends with a coating 14 of resistance material in ribbon form spiralled about such rod between such bands.
  • the coating 14 takes the form of a rhomboid. Accordingly, the shortest path between the terminals 12 and 13 is a line 20 drawn diagonally of coating 14 be tween the wide angled corners 21 and 22, resulting in high current concentrations at such corners.
  • An electrical resistor comprising a rod of dielectric material having an electrically conductive coating thereon in the form of a ribbon spiralled thereabout along its length and having low resistance terminals at the rod ends comprising coatings on the rod that unite with the conductive ribbon along lines running at an angle of 90 with respect to its linear dimension.
  • An electrical resistor comprising a rod of dielectric material having an electrically conductive coating thereon in the form of a rectangular ribbon spiralled there about along its length, and low resistance terminals comprising conductive coatings extending about such rod along and in union with the ends of such ribbon.
  • An electrical resistor comprising a rod of dielectric material having an electrically conductive coating thereon in the form of a ribbon spiralled thereabout along its length and having low resistance terminals at the rod ends extending about such rods and that unite with the conductive ribbon along lines perpendicular to its linear dimension.
