Definitions

  • the invention is in the field of electrical switching devices, the at least one operable by means of a shift shaft Have switching contact system, the contact surfaces in the run essentially parallel to a given level, and is in the constructive design of a switching chamber housing applicable, the switch contact system and others Switch parts takes up and that from at least two Housing parts exist.
  • the switching chamber housing consists of a front and a rear housing part, each of which has a circumferentially closed surface and which absorb the mechanical forces that occur when the movable switching contact is actuated. These forces act essentially perpendicular to the contact surfaces of the switch contact system.
  • the two housing parts lie - in a conventional manner in low-voltage circuit breakers - along a dividing joint that runs parallel to the axis of the switching shaft and in the position of use of the switchgear vertically between the front housing wall and the rear wall of the housing other contact is assigned to the rear housing part, this assignment requires a perfect fit mutual alignment of the housing parts.
  • Another known low voltage circuit breaker is to strengthen the connection between the housing parts an additional element is used.
  • This dovetail-shaped Element is arranged between the housing parts and extends along the side walls of the housing parts within of a channel formed by both housing parts to pick up the item.
  • This element is used for Increase the strength of the connection of the housing parts in With regard to the power transmission, but contributes at most in one level, namely the horizontal, to the other Alignment of the housing parts at. It also shows a relative high cost of materials and an additional Assembly effort on (US-PS 4,899,253).
  • the housing parts to be joined together can be form-fitting Alignment arrangements for inevitable mutual Alignment (centering) of the housing parts may be provided.
  • the housing parts can be toothed on the dividing joints.
  • the positive alignment arrangements are appropriate the outer walls of the housing parts or other suitable Locations, for example arranged on phase partitions.
  • The is particularly useful for large switchgear, such as circuit breakers with single pole opening required for everyone Pol have a coupling pin to the coupling pin axially to secure.
  • the form-fitting alignment arrangements can be advantageous as molded flags on one of the two to be joined Housing parts and as recesses for receiving the above Flags in the other of the housing parts to be joined be trained. - Because of the molded flags on the one housing part and the recesses in the other Housing part are after the beginning of the intervention of the flags into the recesses if the housing shells are already there mutually aligned, but not yet complete are joined, there are still continuous windows.
  • the positions and sizes of the form-fitting ones are advantageous Alignment arrangements chosen so that before the final Assembling the housing parts, in one position, in which the switch parts that are already on these housing parts are already aligned with each other are, further switch parts, especially connecting parts can be assembled.
  • At least one molded alignment arrangement positioned and size trained that in the state described above waves or other connecting parts, for example one or more Coupling bolt between the contact and the drive can be created after the complete assembly of the Housing parts by the flags of the form-fitting Alignment arrangements are fixed laterally.
  • An arc quenching chamber is advantageous in a housing part, if necessary, a switching gas damper and a Arc quenching chamber lid integrated. It is consequently no special parts required for this.
  • the switching gas emission takes place through the end housing part.
  • Outlet openings are advantageous in the division joints provided through the connecting rails of the switching device are brought out.
  • the Assemble the housing shells by means of the side walls of the Outlet openings with inserted connection rails one additional alignment effect on the housing parts realized.
  • FIG. 1 schematically shows a perspective view of the Front of a switch chamber housing according to the invention Inclusion of a switch contact system of an electrical Switching device, for example a low-voltage circuit breaker, from the front right.
  • FIG. 2 shows schematically a perspective view of the Back of the switching chamber housing according to Fig.1, from back left.
  • the switching chamber housing consists of several Housing parts, namely a lower shell 2, an upper shell 3 and an intermediate shell 4 by horizontal Gaps 5; 6 are separated from each other.
  • the positive alignment arrangements 9 are in the division joint 5 on the upper shell 3 as molded-on flags 10 the two sides (one side not visible) and as recesses 11 for receiving the flags 10 in the intermediate shell 4.
  • In the division 6 are on the intermediate shell 4 molded flags 13 (one side not visible) and on the lower shell 2 recesses 14 for receiving the molded flags 13 provided.
