  • Such a switching device is known for example from DE 101 29 498 Cl.
  • the switching mechanism of this known switching device comprises two mutually parallel side plates (also referred to as lock plates or side panels), between which the other mechanical elements of the switching mechanism are arranged.
  • the side plates are riveted with spacers, which can serve as axes for different levers of the switch lock at the same time.
  • the switch lock is made as a prefabricated unit in the known switching devices and fastened by means of screws frictionally after the riveting operations on a support member of the switching device.
  • the side plates are received on the bottom side by slot-shaped guides of the carrier part and are supported by their bottom ends on stop surfaces of the carrier part.
  • the support member is used in these known switching devices at the same time as a support member for receiving other essential functional parts of the switching device, such as the switching shaft, the switching pieces, the extinguishing chambers, the busbars etc. After the complete assembly of the support member this is inserted into a lower part of the housing of the switching device and associated with this. Subsequently, then the connection of the upper part with the lower part.
  • the invention has for its object to provide a switching device of the type mentioned, in which the assembly costs compared to known comparable switching devices can be significantly simplified.
  • the invention is based essentially on the idea not to screw the switch lock with the support member, but by means of appropriately designed edge portions of the side plates on the support member, for. to be secured by clamping.

  • the switching mechanism For attachment of the switching mechanism to the support part, therefore, first the switching mechanism must be slightly obliquely downwards from above so that the parts located at the first end sides engage under the corresponding projections of the support member. Subsequently, the switching mechanism is then pivoted with its other side down and introduced the tongue-shaped fixing elements in the associated receptacles of the support member. Now only with a corresponding tool, the respective fixing member must be rotated about its longitudinal axis until either jamming between the walls of the receptacle and the fixing element and / or the fixing element no longer through the preferably slot-shaped insertion opening of the recording réelle- is drawable.
  • the side plates and other mechanical items are designed such that a pre-assembly of the switching mechanism without riveting and / or screwing the other items with the side plates is feasible, ie, the loosely interconnected parts are through the fitter or a mounting aid held together.
  • the thus pre-assembled switching mechanism is then connected in the manner described above by fixing the side plates on the support member with this and the optionally used assembly aid removed again.
  • the switching device according to the invention is composed essentially of at least three pre-assembled modules, namely a lower part, a center part connected to the lower part, which forms the support member for the switching mechanism, and a top part can be fastened to the central part lid part , At least part of the outer wall areas of these modules form the outer walls of the housing of the switching device.

  • a modular switchable device is designated by 1, which in the sentlichen from four preassemblable modules can be assembled, namely from an L-shaped lower part 2, a connected to the lower part 2 middle part 3, which serves as a support member for a switching mechanism 4 and for other functional elements of the switching device 1 (eg for the contact system, the shift shaft and the arc extinguishing chambers) is used, an unillustrated, partially inserted into the vertical leg 5 of the lower part 2 edge part which comprises a switching mechanism 4 triggering trigger system, and also not shown cover part.
  • the outer wall portions 6- 9 of these modules together form the outer walls of the housing 10 of the switching device 1, so that a separate housing for the switching device 1 can be omitted.
  • the lower part 2 of the switching device 1 is used essentially to cover the attached to the central part (support member) 3 further functional elements, provided that they are arranged below the switching mechanism 4 (essentially the contact system with switching shaft).
  • the switching mechanism 4 is in a conventional manner (see, for example, the aforementioned DE 101 29 498 Cl) of two side plates 11, a drive lever 12 with actuating handle 13, a toggle mechanism 14 with spring energy storage 15 and other elements together.
  • the switching mechanism While in known switching devices, the switching mechanism is first preassembled, the side plates are connected by spacers (eg partially as axes for the functional parts of the switching mechanism) by riveting and / or screwing together, takes place in the switching mechanism according to the invention only a loose assembly of the items Switch lock 4.

  • the invention is not limited to the embodiment described above.
  • the receptacle of the support member is bounded on the upper side by a slot-shaped insertion, so that after rotation of the tongue-shaped fixing in the recording this is not pushed back through the slot-shaped Ein Industriesöffhung.

  • the switching device according to the invention can also be constructed such that it can be assembled instead of four or three preassembled modular units, wherein the trigger mechanism is arranged for example in the lower part. Also in this case, the outer wall portions of the modules should form the outer walls of the housing of the switching device. LIST OF REFERENCE NUMBERS

Abstract

L'invention concerne un appareillage (1) de commutation, notamment un commutateur de basse tension, comprenant un boîtier (10) et un verrou (4) de commutation. Selon l'invention, le verrou (4) de commutation est relié avec une partie (3) porteuse de l'appareillage (1) de commutation et comprend deux plaques (11) latérales disposées parallèlement l'une à l'autre entre lesquelles sont disposés les autres éléments (12, 14, 15) mécaniques du verrou (4) de commutation. Pour réussir à réduire nettement la complexité du montage pour la fabrication de l'appareillage (1) de commutation par rapport à des appareillages de commutation comparables connus, l'invention propose de ne pas visser le verrou (4) de commutation à la partie (3) porteuse, mais de le fixer au moyen de zones configurées en conséquence des plaques (11) latérales du verrou (4) de commutation par serrage avec la partie (3) porteuse.
