Definitions

  • This invention relates to electrical components, and more particularly to the provision of connecting wires to such components.
  • Pile or layer condensors which are produced from a master condensor wound on a drum by dividing the master condensor in the radial direction and in the circumferential direction have what are termed frontal sides, which sides have a metallic layer applied thereto for commonly connecting the condensor plates of like plurality. Each condensor usually has two such frontal sides.
  • the distance of the connecting wires at the building component may vary only in very definite limits due to the predetermined tolerance of the distance and diameters of holes.
  • space holders at the building element for example, bottom platelets or cups with perforations.
  • the distance is determined with the aid of a device when the wires are applied, for example with the aid of a gauge when the wires are soldered on.
  • the distance can be adjusted during a pressing operation, or the distance is produced mechanically only prior to insertion into the conductor plate.
  • the distance of the external connecting wires of an electrical component is determined by applying a first contact layer to the component having a higher melting point than a second contact layer which is applied over the first contact layer.
  • the contact wires are then pressed into the metal of the second contact layer whereupon they are embraced thereby and adhere to the first contact layer.
  • Heat is applied to assist in forcing the connecting wires through the second or outer contact layer.
  • FIGURE illustrates a stack or layer condensor having connecting wires provided according to the invention, the condensor being shown in cross-section.
  • the present invention may be employed for a variety of electrical components.
  • the description herein is directed to such condensors and the application of the invention to other components will be readily understood by those skilled in the art.
  • the preferred method comprises the provision of two superposed layers of metal for contacting the connecting wire.
  • the outermost layer of metal is softened by heating and the connecting wire is pressed into the softened metal until it strikes and adheres to the inner metal layer.
  • the inner metal layer has a higher melting point than the outer metal layer and melting of the inner layer is prevented by applying only sufficient heat and pressure to permit pressing of the connecting wire through the outer layer.
  • the inner layer which is employed for contacting the thin metal condensor plates and which has a high melting point is provided preferably as aluminum and/or copper and the outer contact layer employed for the application of the connecting wires is provided preferably from SnPb, white metal or babbitt metal 10.
  • the contacting of the connecting wires within the outer layer is best accomplished by welding. By an appropriate dosification of the welding energy, the connecting wires can be applied under radial connection such that they completely penetrate the low melting point outer metal layer and adhere to the high melting point inner metal layer, which must not be changed by the welding energy, the surface of the inner layer which is adjacent and contacting the outer layer only adhering to the connecting wire. In this manner, the wire distance is determined.
  • the total tolerance of the distance of botlrconnecting wires results from the coiling precision of the master coil and from the thickness tolerance of the first contact layer which has the high melting point.
  • a stack or layer capacitor is provided with connecting wires according to the present invention and includes metallic layers 2 carried by dielectricum foils l in a superposed construction. Alternate layers overlap on opposite sides of the condensor, the frontal sides, to which is applied a first metallic layer 3 having a high melting point, for example, aluminum and/or copper.
  • Second frontal metallic contact layers 4 are applied over the layers 3 from a metal having a lower melting point, for example, SnPb, white metal or babbitt metal 10.
  • the frontal layers 4 are softened by heating and the connecting wires 5 are pressed into the layers 4 and thereby welded thereto.
  • the connecting wires 5 are pressed into layers 4 until they contact the inner layer a 3, which through controlled application of heat is not softened dueto its higher melting point.
  • the layers have a width B with a tolerance of 1: 0.05 mm.
  • a stacked layer type capacitor for being supported on its lead wires in spaced apart openings on a printed circuit board comprising: a plurality of planar stacked dielectric layers, a metal coating on each of the dielectric layers forming plates of the capacitor, a pair of first planar metal layers having a relatively high melting point each contacting alternate plates of said capacitor at opposite edges thereof, the plane of said first planar metal layers being perpendicular to the stacked layers, a second planar metal layer having a relatively low melting point overlying each of said pair of first metal layers and extending substantially across the entire thickness of said capacitor, a lead wire embedded in each of the relatively low melting point metal layers and having a longitudinal surface thereof contacting ,the relatively high melting point metal and being welded thereto such that each of the lead wires extends from the stacked layers in generally the same direction and have lateral spacing between their longitudinal axis which is determined by the'lateral spacing between the external surfaces of the high melting point metal.
