Definitions

  • the invention relates to a contact pairing with a double contact point for an electrical Switching device according to the preamble of claim 1.
  • the contact pieces generally consist of silver-containing or similar material.
  • the contact surface is covered by a flat or specially shaped e.g. spherical Surface formed. Typically, this occurs at the actual contact points one point-shaped contact surface each, so that the position is unstable or indifferent is.
  • the system is stimulated to vibrate, for example, by the impact of the Contact bridge when switching on the fixed contact pieces.
  • the vibrations can subside or persist for a long time. By these vibrations are loaded on the contact bridge; the buzzing that may occur are perceived as disturbing.
  • the object of the invention is to have a contact pairing of the type mentioned to design the corresponding contact pieces so that vibrations, excited by Switch-on processes and other effects, e.g. Shocks to be avoided.
  • the one contact point has a support point. B. flat, crowned, etc. trained, whereas the other contact point with two defined contact surfaces is trained.
  • the two contact surfaces or points of the other contact point are separated from each other by a valley, the extension of which is in the direction of the longitudinal extension the contact bridge runs.
  • the three-point support corresponds to a statically determined one Storage.
  • a contact bridge 10 is formed by an elongated flat strip material, which has an elevation 11 in the middle and one in the area of the two ends Contact piece 12 and 13 carries that with a solder layer 14, 15 on the contact bridge 10 are soldered on.
  • One contact piece 12 has a surface 16 through a spherical spherical surface is formed, as a result of which a point-shaped contact surface relative to a fixed contact piece 17 18 is formed.
  • the other contact piece 13 has two spherical elevations 19, 20 through a valley 21 are separated from each other, which runs in the longitudinal direction of the contact bridge 10, so that the two elevations 19 and 20 lie on both sides of the longitudinal center line L-L.
  • a swing around the longitudinal center line L-L is avoided because the support is a statically determined support. This also prevents the humming and vibrations.
  • the shape of the spherical elevations 19 and 20 is not essential; It is advantageous if the distance between the crowned elevations is transverse to the longitudinal extent or becomes as large as possible to the longitudinal center line L-L; it is also convenient to determine the depth of the Tales 21 to be as large as possible in relation to the convex elevations 24 and 25, because there may be erosion in the course of the electrical life.
  • the procedure for producing the contact piece 13 is as follows:
  • the contact piece 13 is initially flat and is over the solder layer 15 on the contact bridge 10 soldered. Then the contact bridge 10 together with the contact piece 13 deformed so that the elevations 19 and 20 are formed; be there on the contact piece 13 opposite surface of the contact carrier 10 wells 26 and 27 generated.
  • the contact pieces are soldered; it there is of course also the possibility that the contact pieces riveted or from the The contact bridge material is punched or pressed and then silver-plated.
