Definitions

  • the invention relates to a contact spring for a bistable relay for switching high currents.
  • the invention is based on a contact spring for a bistable relay for shading high currents, which consists of an elongated, one-piece metal sheet with a clamping end and a contact end, between which a bending zone is formed
  • a contact spring for a bistable relay for shading high currents which consists of an elongated, one-piece metal sheet with a clamping end and a contact end, between which a bending zone is formed
  • Invention characterized in that at least one strand of current-conducting material is provided, the end of which is connected in a current-conducting manner to the clamping end or to the contact end of the metal sheet.
  • the currents are thus divided between the actual metal sheet and the strand or strands.
  • These are easily movable and do not noticeably or disadvantageously increase the easy bendability of the metal piece (metal sheet), which can therefore be designed in accordance with the mechanical requirements, in particular the easy bendability.
  • the other aspect of the invention is based on a contact spring for a bistable relay for shadowing high currents and is characterized in solving the above-mentioned object of the invention, characterized in that the contact spring consists of a plurality of metal plates, one on top of the other, which are connected to one another at their ends.
  • the contact spring consists of a plurality of metal plates, one on top of the other, which are connected to one another at their ends.
  • the aforementioned first embodiment is preferably characterized in that the bending zone is formed by an elongated strip, one of the strands being arranged on both sides of the strip. So here you have at least two strands, which can therefore absorb a relatively high current.
  • Another embodiment is characterized in that the bending zone is formed by two spaced-apart, parallel strips, between which at least one strand extends. This embodiment is particularly symmetrical in operation and no canting can occur when the contact spring is bent.
  • the electrically conductive connection between the ends of the strand and the actual contact spring must be able to withstand high thermal loads.
  • a conventional soldered connection is not suitable for this. Therefore, the invention is further characterized in that the strands are clamped between two contact plates.
  • the clamping force can be applied, for example, by spot welding, which is preferred because of the high current transfer areas, or also by screws, clamping or riveting.
  • FIGS. 2 and 3 now show details of the contact spring 1 .
  • the contact spring 1 has an H-shaped profile, the bending zone 6 being formed by an elongated strip 8.
  • the front transverse strip 10 is extended to a fork-shaped end on which the contact pieces of the contact zone 5 are formed.
  • the mechanical properties, in particular the bending properties of the strip 8 in the bending zone 6, are designed so that the necessary easy bendability for a bistable relay is present.
  • the strip 8 has a small cross-section in order to nevertheless absorb high currents of the order of 25 amperes can are two strands 11 are provided electrically parallel to the strip 8, the ends of which are suitably connected to the transverse strips 9, 10. These are stranded or twisted strands, the ends of which are electrically conductively connected to the material of the actual contact spring 8, 9, 10 by an additional contact plate 12. Spot welding is preferably provided here.
  • a box profile with two of the strips 8 is provided, which are fastened to the transverse strips 9, 10 in parallel and at a distance from one another.
  • At least one strand 11 is provided approximately centrally between the transverse strips 9, 10 and therefore the longitudinal strips 8 are connected in parallel.
  • This embodiment is characterized by a particularly good torsional rigidity and torsional stability because the contact is better managed.
  • fewer connection points, position 12, are provided here than in the first exemplary embodiments according to FIG. 2.
  • the third embodiment according to FIG. 5 makes use of the second principle mentioned, wherein without the strands 11, a plurality of metal plates 13, preferably of the same format, are placed one above the other. They are connected at their ends to form a clamping end 14 and a contact end 15, for example welded.
