Definitions

  • the invention relates to a switchgear housing for an electromagnetic switching device that is a magnetic chamber having a magnetic yoke and a magnetic armature, wherein on Magnetic chamber bottom of the switchgear housing two magnetic support areas with different elastic suspension for Storage of the magnetic yoke are present.
  • the invention has for its object a switchgear housing of the above type in such a way that a Bouncing back of the magnet armature on simple and at the same time effectively diminished.
  • the magnetic chamber floor is designed to vibrate and on its the interior of the Switching device housing facing surface a support strip has, the ends of which serve as magnetic support areas, a first magnet support area at one end only is held by magnetic chamber floor.
  • the second magnet support area is ribbed with closed frame profiles, because hereby a hard resilient magnetic support area in a simple manner is realized. If between the magnetic yoke and the Support strip an insert rubber is inserted, can hereby especially depending on the height of the support strip influence the spring properties of the soft magnetic contact area.
  • the housing 1 is one Protection 2, in the magnetic chamber 3 housed the magnet system is.
  • This essentially consists of a magnetic yoke 4, a magnet armature 5, a coil 6 with coil connections, a contact carrier 7 and a conical spring 8.
  • Das Magnet system is with its magnetic yoke 4 on the bottom of the magnetic chamber 9 of the contactor housing 1 with the interposition of an insert rubber 10 stored.
  • the magnetic chamber base 9 is included two not shown here, different resilience Magnet support areas 11, 12 formed.
  • the one magnetic support area 11 has a soft, the other 12 a relatively hard suspension (see FIG 3).
  • FIG. 2 shows the underside of the contactor housing 1 with the closed Magnetic chamber floor 9 and frame profiles 15 shown.
  • 3 shows an interior view of the contactor housing 1 with the magnetic chamber base 9.
  • the magnetic support areas 11, 12 are on the inside of the magnetic chamber base 9 as a support strip formed, one end of the magnet chamber floor on all sides 9 is enclosed and its other end in passes over a wide, reinforced area 13. These two Ends serve as magnetic support areas 11, 12 with the already mentioned soft and hard suspension.
  • Four on the bottom of the magnetic chamber 9 projecting ribs 14 serve for lateral guidance of the magnetic yoke 4.
  • the magnetic chamber bottom 9 is relative thin-walled.
  • the soft magnetic support area 11 of the support strip is on all sides of the magnetic chamber bottom 9 surrounded, on the other hand with the greatest possible distance to the Walls of the contactor housing 1 is connected.
  • the other, hard Magnet support area 12 is with closed frame profiles 15 ribbed according to FIG 2. Through the wide area 13 is on the hard support side for the magnetic yoke 4 a wide magnetic support given, while on the soft support side narrow, not completely continuous magnetic support is available.
  • the contactor housing 1 described above is special Training of the magnetic chamber base 9 rebound-optimized. This means that the shock processes that occur due to the relatively high closing speed when closing a AC magnets result in extremely well cushioned be without the magnet armature 5 with the contact carrier 7 (see FIG. 1) bounces back to the "OFF" position.
  • the magnetic chamber base 9 is completely closed at the bottom, with possible problems with creepage distances and clearances between the coil 6 and the underside used as the mounting level of the contactor housing 1 excluded from the outset become.
  • the effect of the above-described contactor housing 1 is based on following technical measures.
  • the very thin, all around connected magnetic chamber floor 9 has with the soft support area 11 results in a progressive spring characteristic.
  • the damping component caused by the contactor housing 1 not so dependent on temperature and humidity such as. a resilient cantilever with linear characteristic. In front this is all due to the temperature and moisture content dependent elasticity property of this used plastic.
  • the insert rubber 10 has the following Influence on the dampening effect. He is at rest, i.e. on the soft support area 11 and comes after its deflection over a large area on the magnetic chamber floor 9 to the edition.
  • spring characteristics 16, 17 are Representation of the spring properties of the magnetic chamber base 9 shown.
  • the spring characteristic curves 16 below show in principle the effect when inserting an insert rubber 10, the upper spring characteristic curves 17 when such is not used Inlay.
  • the spring characteristics 16, 17 initially have one relatively flat course and then increase progressively, i.e. with increasing travel or greater deflection, the Power consumption disproportionately.
