Definitions

  • the invention relates to a releasable connection contact for high-current conductors, in particular busbars in electrolysis devices.
  • Such contact points are usually machined and smoothed so that they are as flat as possible and can ensure a large contact surface and intimate contact.
  • the invention has for its object to avoid voltage losses at contact points or on detachable connection contacts for high-current conductors or to make them lower.
  • the object of releasable connection contacts for high-current conductors, in particular busbars in electrolysis devices is achieved in that at least one of the contact surfaces of the connection has sharp-edged roughness peaks.
  • Such roughness peaks can be in the form of burrs that by cutting z. B. grooves are generated.
  • these roughness peaks can also be present as a file structure, knurled structure or tip structure of the surface caused by spark erosion.
  • * the height of the roughness peaks is 0.1 mm to 0.8.
  • Such a tip structure of at least one of the contact surfaces ensures intimate contact of the contact surfaces joined together by pressing pressure and avoids contact resistance. It can be assumed that the roughness peaks or the sharp-edged profiles provided according to the invention are easier to deform than a completely flat contact surface, which despite all the processing effort apparently has only a few spherical contact surfaces.
  • one or, if there is a risk of corrosion, both contact surfaces, but in any case the contact surface with the roughness tips, are provided with a layer of noble metal.
  • the thickness of this precious metal layer is 0.5 to 5.0 x 10 -3 mm.
  • noble metals are understood to be silver, gold and platinum metals, such as osmium, iridium, platinum, ruthenium, rhodium, palladium. Silver or platinum are expediently used as the noble metals of the layer.
  • the contact surface with the roughness tips has an electrolytically applied silver layer with a thickness of about 1.0 x 10 -3 mm and the smooth contact surface may have a layer of the same nature or it may not be post-metallized.
  • the contact surface with the roughness tips is provided with a silver layer with a thickness of 1.0 ⁇ 10 -3 mm, while the smooth contact surface. carries a 0.5 x 10- 3 mm thick platinum layer.
  • the configuration of the contact surfaces according to the invention has the advantage that losses due to voltage drop are drastically reduced and a higher current load on the contact can be carried out.
  • Fig. 1 is a longitudinal section through a releasable connection contact according to the invention.
  • a flat cylindrical connector body 1 from z. B. copper with a continuous bore 2 the busbars 3 from z. B. welded copper.
  • the contact surface of the connector body 1 serving for the current transfer has roughness peaks 4.
  • the flat-cylindrical connector body 1. is with the smooth surface of a cylindrical metal bolt 6 from z. B. copper; which has a threaded bore 7 (thread not shown) in contact.
  • the connector body 1 is pressed onto the cylindrical bolt 6 by means of a screw connection (not shown) introduced by 2 and 7. With 5 precious metal layers are designated.
  • a screwed contact point of a copper busbar (copper / copper material combination) was designed in accordance with the invention.
  • one of the surfaces was provided with concentrically arranged, closely spaced 0.5 mm deep grooves. Equipped with the grooves or sharp-edged ridges contact surface was electrolytically plated and generates a 1.0 x 10- 3 mm thick silver layer.
  • a Voltage drop of 5 mV measured. This corresponds to a quadrupling of the otherwise usual load with the same voltage drop and thus means a substantial reduction in the contact areas to be made available.
