Definitions

  • the invention relates to a hinged armature mounting, preferably for an electromagnetic release according to the preamble of claim 1.
  • An electromagnetic release is a device in which, by changing an effect size with the help of a drive system, the effect size is converted into mechanical movement.
  • Electromagnetic releases are preferably used as short-circuit protection. They often have a hinged anchor magnet as the drive system. The response value can be set by a spring acting on the armature. The electromagnetic releases are of great importance for the function of the current-limiting circuit breakers and quick switches.
  • a hinged-armature magnet is known from FR-PS 15 41 052.
  • the hinged anchor is mounted in such a way that it is attached to two correspondingly shaped pins arranged in front of the yoke cutting edge via two cut-in rectangular recesses in the hinged anchor, and is secured by a tension spring engaging behind the yoke blade on the hinged anchor.
  • the tension spring also determines the rest position of the hinged anchor. It can be seen that the hinged anchor is secured in the bearing in the direction of the pins only by the tension spring. This proves to be disadvantageous because under certain circumstances, e.g. when the trigger is subjected to shock, the hinged anchor can jump out of its storage. Appropriate reinforcement of the tension spring is not possible because the response value of the hinged armature magnet and thus the trigger is set via the tension spring force.
  • a hinged anchor mounting of the type mentioned is known from FR-A 2 474 236.
  • the yoke leg guiding the hinged anchor has a trapezoidal ridge in a recess of the free leg end and a continuous channel or two channel sections are formed on the hinged anchor, which rest on the ridge.
  • the return spring is attached to the hinged armature outside the yoke area and to the yoke itself on an extension of the yoke leg supporting the magnetic core. The return spring thus runs approximately parallel to the yoke leg that supports the hinged armature.
  • the invention has for its object to improve the hinged armature bearing in a hinged armature magnet of the type mentioned to increase the functional reliability.
  • the advantages achieved by the invention are, in particular, that regardless of the installation position of the hinged armature magnet and in the event of a shock load, the hinged armature remains securely in its storage. Furthermore, the hinged armature bearing according to the invention achieves an exact rest position of the hinged armature with a defined air gap, as is required to achieve a constant, precise response value for the trigger.
  • hinged anchor is designed as a fork and carries the detents on the free fork ends.
  • the locking lugs are formed on the hinged anchor by a shearing action during a punching process, see claim 3, just as the limiting pin according to claim 4 protrudes or is pressed out of the surface of the web-like extension of the yoke by plastic shaping.
  • FIG. 1 shows a folding armature magnet 1 for an electromagnetic release that is not described in detail.
  • the hinged armature magnet 1 has a yoke 2 which is bent at right angles and consists of a soft magnetic material (iron). On the inside of one yoke leg, a cylindrical iron core 3 is attached, on which a coil 4 is pushed. The free end of the other yoke leg is shoulder-shaped by a centrally arranged web-like extension 8. The shoulders are bevelled on the back so that the outer edges form a cutting edge (yoke cutting edge 5).
  • the hinged anchor 6 has two forked legs 16 at one end.
  • the hinged anchor 6 is mounted in such a way that the legs 16 rest on the yoke cutting edge 5 and, for the lateral locking, fit the web-like extension 8 between them.
  • the ends of the legs 16 of the hinged anchor 6 are provided with locking lugs 10 which engage behind the yoke cutting edge 5.
  • the locking lugs 10 are integrally formed on the hinged anchor 6 by means of shearing action during the punching process.
  • a shackle spring 12 which is designed as a tension spring, is suspended, the other end of which is attached to a cross pin 13 of the web-like extension 8 of the yoke 2.
  • the shackle spring 12 acting on the hinged anchor 6 holds it in the rest position in which the hinged anchor assumes the "open" position, ie is not tightened.
  • the hinged armature magnet 1 responds within a very short time, and the hinged armature is attracted.
  • a release lever 14 of a switch lock (not shown in more detail) is brought into position 15, and thus the switch lock is unlocked, the contacts of the switching device are opened and the short-circuit current is switched off.
  • hinged armature magnet 1 such that the hinged armature 6, when triggered, reverses from the "tightened” position (FIG. 2) into the hinged armature on the iron core 3, from the spring 12 to the “dropped” position (FIG 1), in which the hinged anchor is removed from the iron core 3, is spent, whereby he actuates the switch lock. The storage would then remain unchanged.
