Definitions

  • the invention relates to a miniature relay arranged in a housing with an angular hinged armature, which is tiltably mounted with its inside on the yoke of the magnet system, so that in one position one leg of the hinged armature the core and in the other position the other leg of the Folding anchor is approached to the yoke except for an air gap and a contact system is arranged on the side of the folding anchor facing away from the yoke, which contact system can be actuated by one leg of the folding anchor, according to patent 2,516,502.
  • the relay according to the main patent is very simple and can be easily manufactured because the parts of the magnet system in the housing are only held by shoulders molded onto it, so that when the housing is assembled, the magnet system including the angular hinged armature is automatically brought into the correct position .
  • the contact system is completely independent of the magnet system, so that both systems after training and Material can be optimally designed for their specific purpose without having to choose a compromise between the contact function and the magnet function.
  • the object of the present invention is to modify such a miniature relay in a simple manner so that it has bistable properties.
  • the miniature relay according to the main patent, contact system and magnet system are independent of each other.
  • a hinged anchor is used as the moving part of the magnet system, which corresponds to the required magnetic flux can be dimensioned sufficiently thick.
  • the armature is formed by a flexible contact tongue, which must be made relatively thin because of its easy operability, whereby the magnetic flux through the contact tongue is limited.
  • the magnetic flux which is caused by the permanent magnet, is divided into two paths, namely via the yoke and the core back to the permanent magnet and the other through the yoke end, one leg of the hinged armature and the end of the core back to the permanent magnet.
  • This second path gives the holding force that the permanent magnet exerts on the hinged anchor to hold it in a certain position.
  • the first-mentioned path via yoke and core has the lower magnetic resistance, so that a larger magnetic flux flows through this path. This may have the consequence that the holding force exerted on the folding anchor is not sufficiently large.
  • the two magnetic fluxes are influenced so that there is sufficient holding force for the hinged armature.
  • This can be done by installing a narrow point for the magnetic flux in the first magnetic path.
  • This can be done in a simple manner in that the yoke has an incision or breakthrough so that the iron cross-section is reduced at this point and thus there is an increased magnetic resistance.
  • a side incision in the yoke has the advantage that it is very easy to manufacture, while a breakthrough has the advantage that the magnetic flux flowing in the yoke can be divided symmetrically.
  • the transition point at which one leg of the hinged armature bears against the core or its pole piece is provided with an enlarged cross section according to the further embodiment of the invention , ie the magnetic resistance is reduced at this point.
  • the magnet system of the relay is arranged in a housing 10 into which the contact pins 20 are molded.
  • the magnet system itself consists of the core 11 and the yoke 12, the coil 14 being arranged on the core 11.
  • the angled hinged armature 13 is tiltably mounted on the edge of the leg of the yoke 12 arranged above the coil.
  • the contact spring 19 is actuated, which cooperates with the fixed contact 22.
  • the contact arrangement is only shown schematically and can also consist of a larger number of contacts.
  • the parts of the magnet system are held in the housing 10 by the shoulders 15 and 17, the shoulder part 16 holding the hinged anchor 13 in position, while the shoulder part 18 secures the yoke 12 with the core 11 and the coil 14 in their position.
  • the permanent magnet 21, which is polarized in the longitudinal direction, is arranged in the magnetic circuit between the yoke 12 and the core 11.
  • the permanent magnet 21 is arranged on the core 11 which is elongated beyond the coil and, on the other hand, bears against the underside of the yoke 12.
  • a current flowing through the coil 14 generates a magnetic field which is superimposed on the magnetic flux of the permanent magnet 21.
  • the hinged armature 13 is held in place by the permanent magnet 21, either by the leg 13a resting on the yoke 12 or the leg 13b at the end of the core 11.
  • an opening 26 is provided in the yoke 12, as can be seen in particular from FIG. 2.
  • the iron cross section of the yoke 12 is reduced at this point and the magnetic resistance is thereby increased. This ensures that a larger part of the magnetic flux of the permanent magnet is available for holding the hinged armature.
  • the cross section of the core is widened at its end, for example by inserting a pole piece 25. This reduces the magnetic resistance between the core 11 and the leg 13b of the hinged armature, so that it is also in this way Circle a better magnetic flux is achieved.
  • the permanent magnet 21 lies against the yoke 12 over its entire width.
  • a lateral incision can also be made in the yoke 12, which on the one hand is easier to produce than the opening 26, but on the other hand causes an asymmetrical magnetic flux over the cross section of the yoke.
  • the permanent magnet with a pole is arranged on a pole shoe 24 which connects to the core 11.
  • This pole piece is L-shaped, so that a permanent magnet 21 with larger dimensions can be used. If, on the other hand, a pole shoe 24 of U-shaped cross section is used, a better transition of the magnetic flux to the leg 13b of the hinged armature 13 is obtained, in a manner similar to that achieved by the pole shoe 25 according to FIG. 1.
  • the yoke 12 also has a cutout 23 into which the permanent magnet 21 projects with a pole. This results in a particularly good transition of the magnetic flux from the permanent magnet 21 to the yoke 12 and a further enlargement of the permanent magnet 21.
  • the yoke cutout 23 can at the same time be used to reduce the magnetic flux in the yoke 12 by making it larger than the protruding permanent magnet 21 and the permanent magnet is arranged eccentrically in the cutout 23, as can be seen from FIG. 4.
  • the angled hinged anchor 13 can additionally be under the action of a weak spring, which can be realized, for example, by a film connected to one leg of the hinged anchor.
