Definitions

  • the invention relates to a sliding contact with a base body made of a wire.
  • sliding contacts are known inter alia from DE 40 20 700 A1.
  • the ones revealed here Sliding contact wires have been rounded off at their edges by means of a laser beam.
  • US 5,315,758 A and US 5,416,969 A are known sliding contacts formed from sheet metal strips, which carry contact bodies at their ends.
  • Such sliding contacts are for example in Potentiometers, in position sensors or in rotary switches together with a metallic one Used mating contact.
  • the invention has for its object to improve the known sliding contacts.
  • the object is achieved in that at one end of the wire a Sliding contact body is arranged.
  • the main body of the Contact us to choose a cheap, resilient material while that transmitting the energy Part as Schteifternoplasty from another, optimized for energy transfer material can exist.
  • Due to the structure of the sliding contact from two different output parts can realize different material properties in a sliding contact so that it adapts to the specific requirements of its intended use can be. It is not necessary, the sliding contact body at the physical end of to arrange wire-shaped body, but he can also at an example by Bending or kinking arising (relative) end of the wire to be arranged on the the wire comes closest to the mating contact.
  • the sliding contact body is arranged on the front side of the wire, but it is also an arrangement of the sliding contact body on the lateral surface of the wire possible. It is expedient that the sliding contact body in the longitudinal direction of the wire over whose one end protrudes. It may also be expedient that the sliding contact body surrounds the jacket at least on a part of its circumference, for example in the form of a longitudinally cut tube.
  • the sliding contact body formed as a ball or as a piece of wire is.
  • the base body and / or the sliding contact body can be in and / or against each other be angled.
  • the diameter of the sliding contact body can be about as large as the diameter of the body. This diameter may preferably be about 50 ⁇ m 150 microns.
  • the sliding contact body of a Noble metal or a noble metal alloy is formed.
  • the sliding contact shown in Figure 1 has a base body 1 made of a non-precious metal spring wire and a sliding contact body 2 made of a precious metal ball (Figure 1a).
  • Sliding contact body 2 is by means of laser welding or resistance welding to the main body 1 welded.
  • Schleiking in which instead of a precious metal ball as a sliding contact body 2 a precious metal wire section is used.
  • the sliding contact body 2 either at the end (FIG. 1a, 2a) or at the lateral surface of the main body (FIG. 1b, 2b) be.
  • Figures 3 and 4 similar sliding contacts are shown, in which the Base body 1 is angled.
  • both the Base body 1 and the sliding contact body 2 angled.
  • the according to Figures 3 and 4 angled sliding contacts are also referred to as so-called scratch grinders.
  • FIG. 6 shows a further embodiment of the sliding contact according to the invention, at the around the main body 1 forming spring wire a semicircular embossed noble metal band is welded as a grinding contact body 2 in the form of a halved tube.
  • the Precious metal band can be made very thin and gains its stability from the bent-through Shape and fixation on the lateral surface of the base body. 1
