Definitions

  • the invention relates to an electrical switching device, in particular a contactor, with an electromagnet system which has a fixed magnetic core and a movable armature which is fastened to a guide component by means of an eccentrically mounted driving pin, the ends of which are cylindrical and coaxial with one another and in bores in the guide component are stored.
  • the invention has for its object to design an electrical switching device such that not only a stroke adjustment for the correct setting of the armature with respect to the core of the magnetic drive during the first assembly, but also a subsequent adjustment of the magnetic drive, for example after certain operating times, is possible in a simple manner.
  • the driver pin in the region between the cylindrical ends has a polygonal part which projects through an adapted opening of the armature and that the peripheral surfaces of the polygonal part have different distances from the common axis of the cylindrical ends of the driver pin.
  • Figure 1 shows a simplified perspective view of part of an electrical switching device, namely a magnet system or a magnetic drive with a magnetic core 1 and an armature 5, both the magnetic core and the armature in this embodiment. each have three legs 2, 3, 4 or 6, 7, 8.
  • the magnet armature 5 is held movably via a stroke 39 and is fastened to a guide component 9 for this purpose.
  • the guide component is shown in simplified form to make the principle clearer. In practice, the guide component can be designed differently to suit the circumstances of the switching device in question. It is important that the stroke 39 of the magnet armature is determined by fastening the magnet armature to the guide component.
  • the magnet armature 5 is fastened to the guide component 9 by means of a driver bolt 10.
  • the ends 11 and 12 of the driving pin 10 on both sides are cylindrical and coaxial to one another. These ends are supported in bores in the guide component 9 or in its encompassing webs 37 and 38.
  • the driving pin 10 has a polygonal part 13 in the area between the cylindrical ends 11, 12, which engages the magnet armature 5.
  • a corresponding, continuous polygonal opening is provided in the magnet armature 5 or in a holding part (not shown) that is firmly connected to the magnet armature, so that the driver bolt 10 starts from one side of the guide component, in the present case from the outside of the web 38. can put through.
  • the polygonal part 13 is advantageously square in cross section in the illustrated embodiment. Depending on requirements, this polygonal part can also be triangular, hexagonal, octagonal, etc. in cross-section. It is essential that the peripheral surfaces 40, 41, 42 and 43 of the polygonal part 13 have different distances 14, 15, 16 and 17 from the common axis 18 of the two cylindrical ends 11 and 12.
  • the distance 14 can be, for example, 3.0 mm, the distance 15 3.2 mm, the distance 16 3.4 mm and the distance 17 3.6 mm.
  • the stroke 39 can be changed between four steps of 0.2 mm, ie by 0.6 mm, according to this exemplary embodiment.
  • one cylindrical end 11 of the driving pin 10 has a smaller diameter than the dimensions of the polygonal part 13, while the other cylindrical end 12 has a larger diameter and at the same time serves as a stop in the holder and indicates the correct seating of the driving pin 10.
  • a marking is provided on the end face 19 of the driving pin 10 to indicate the selected position of the driving pin, as illustrated in particular in FIG. 4.
  • the marking can e.g. B. consist of numbers, which are depending on the use of a fixed arrow 44 on the web 38 ( Figure 1).
  • the surfaces 40 to 43 of the polygonal part 13 can be curved slightly outward. Furthermore, it is advantageous to make the surfaces 20, 21 of the driving pin 10 on both sides of the polygonal part 13 up to the both ends of the polygonal ends 11, 12 slightly beveled after these ends. In this way, it is possible to effect not only an adjustment in the two directions in accordance with the stroke 39, but also an adjustment in the corresponding transverse directions.
  • FIGS. 5 and 6 also show a longitudinal section or a cross section through a simplified electrical switching device, which is equipped in a housing 32 with an upper housing part or cover 33 with fixed contact connecting rails 22 and 23 and fixed contact pieces 24, 25 located thereon.
  • a contact bridge 26 interacts with these fixed contact pieces 24, 25, which carries movable contact pieces 27, 28 and which is held via contact pressure springs 29, 30 relative to the guide component 9 and thus to the magnet armature 5.
  • the guide component 9 can also be provided with an actuating button 31 protruding through the housing cover 33.
  • return springs 34, 35 are provided, which hold the guide component 9 and the magnet armature 5 in the rest position when the switching device is not switched on.
  • the magnet system is also provided with an inserted coil 36.
  • the above-described adjustment or adjustment can be effected in a simple manner by lifting the magnet armature 5 with the connected components out of the housing after loosening the housing cover 33 or upper part, pulling out the driving bolt 10 and rotating it about the axis 18 in the desired position again. -The assembly of the switchgear is then carried out in the opposite way with simple steps.
