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 hinged armature the yoke is approached to an air gap, and a contact system is arranged on the side of the hinged anchor facing away from the yoke, which contact system can be actuated by one leg of the hinged anchor.
  • Such a relay is known from DE-C3-25 16 502.
  • the known relay is very simple and can be easily manufactured because the parts of the magnet system are held in the housing only 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 can be optimally designed according to training and material for their specific purpose, without having to choose a compromise between the contact function and the magnet function.
  • an electromagnetic relay is also known in which a permanent magnet is arranged between the core and the yoke within the angle of the hinged armature in order to achieve bistable properties.
  • the yoke of this relay has an opening for controlling the magnetic flux in the yoke.
  • One pole of the permanent magnet bears against the core by means of a pole piece.
  • a folding armature relay in which a permanent magnet is arranged between the yoke and the core and the connection between a pole of the permanent magnet and the core is made via an L-shaped pole piece.
  • a magnet system for a relay in which a permanent magnet is arranged between the core and the yoke and at the end of the core a pole piece with a larger diameter than that of the core is arranged.
  • the object of the invention is to impart bistable properties to the relay known from DE-C3-2516502 by inserting a permanent magnet into the magnetic circuit and to achieve an improved transition of the magnetic flux, in particular between the permanent magnet and the yoke.
  • the magnetic circuit of the core and yoke is closed by a permanent magnet arranged between them within the angle of the hinged armature and which projects with a pole into an opening in the yoke.
  • 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 extended 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. This causes the angular hinged anchor 13 to tip into the other position. In both positions, the hinged armature 13 is held 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 folding armature, so that a better magnetic flux is also achieved in this circuit.
  • the permanent magnet 21 lies against the yoke 12 over its entire width.
  • 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 also 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 permanent magnet is arranged with a pole 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.
  • 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.
