Definitions

  • the invention relates to a multi-pole circuit breaker with a switching chamber housing, in which a number of interrupters corresponding to the number of poles is arranged side by side, and one common to all poles Switching shaft, with each switching chamber having a fixed and a swiveling one Contact bridge formed contact arrangement, which with the fixed contact arrangement cooperates.
  • Such a circuit breaker is for example from EP 0542 636 B1 known.
  • Each of the contact bridges is in a separate plastic existing shaft segment of the control shaft arranged.
  • To connect the Shaft segments are two axially extending, parallel to each other arranged shift rods provided.
  • the disadvantage of this known circuit breakers among other things, that the assembly of the from Shaft segments and the shift rods existing shift shaft relative is time consuming.
  • an expensive storage of the selector shaft in the circuit breaker switch lock, and when using continuous metal bars often pose problems with regard to the electrical insulation of adjacent switching chambers. After all, that is Torsional stiffness of such a control shaft is low and is usually sufficient not the requirements placed on them.
  • From EP 0 634 051 B1 is a multi-pole circuit breaker with one for all poles common switching shaft known, in which the contact bridges the individual interrupters are also arranged on shaft segments.
  • the middle shaft segment points to it a central pin on both ends, which in corresponding Recesses of the adjacent shaft segments is inserted.
  • recessed levers at the ends of the shaft segments provided to accommodate additional coupling bolts.
  • a disadvantage of this Known circuit breakers include the additional connection via coupling bolts and the also relatively complex storage, to ensure exact positioning of the selector shaft.
  • A1 is a multi-pole circuit breaker with one for all poles common switching shaft known, in which the the switching chambers assigned contact bridges arranged in adjacent shaft segments are.
  • the shaft segments are over Coupling elements made of plastic connected together.
  • the coupling elements consist essentially of a central partition for the electrical insulation of adjacent swiveling contact bridges and from cylindrical on both sides of the partition Share with two mounting pins each, which in corresponding Engage recesses in the shaft segments.
  • a disadvantage of this circuit breaker among other things also the relatively expensive storage of the Switching shaft, which takes place essentially in the area of the shaft segments.
  • a generic circuit breaker according to EP 0 849 748 A2 which is considered to be the closest prior art, is disclosed a multi-pole circuit breaker with a switching chamber housing, in the number of switching chambers corresponding to the number of poles next to each other is arranged, and a common for all poles switching shaft, wherein each switching chamber has a fixed and a pivotable contact bridge trained contact arrangement includes which with the fixed Contact arrangement cooperates.
  • Each contact bridge is made of insulating material assigned to existing shaft segment.
  • the neighboring wave segments are connected to each other via separate coupling elements.
  • the shaft segments each point to the corresponding one Coupling element facing side recesses for receiving connecting bolts extending axially from the coupling elements.
  • the Transition area of the interrupter housing between neighboring Switching chambers is at least partially used as a bearing for the bearing shaft of the Corresponding shaft segments connecting coupling element is formed.
  • This circuit breaker has the same result as that described above of the large friction radius a high friction between the bearings and the Bearing shaft on, which is expensive to reduce the harmful abrasion Measures, for example with regard to the choice of material, require.
  • the invention has for its object a multi-pole circuit breaker specify the type mentioned, the switching shaft in simple Is pre-assembled, has sufficient torsional rigidity and in the interrupter housing for exact positioning no complex ones Stock required.
  • the shaft segments 10-12 (for reasons of clarity the contact bridges 6-8 omitted) by means of identical metallic Coupling elements 14, 15 connected. These each include two tab-shaped parts 16, 17 which are connected to one another via a bearing shaft 18 are connected and facing away from the bearing shaft 18 Side at least two connecting bolts each extending in the axial direction Wear 19, 20 or 21, 22. The distance 23 is between the adjacent connecting bolts 19, 20 and 21, 22 of the respective Coupling element 14, 15 larger than the diameter 24 of the bearing shaft 18.
  • the shaft segments 10-12 each point to the corresponding one Coupling element 14, 15 facing side for receiving the connecting bolts 19-22 recesses 25, 26.
  • the coupling elements 14, 15 comprise in the area between the two tab-shaped Parts 16, 17 at least one extending in the axial direction Pin 27, which with one of the two tab-shaped parts 16 or 17 is firmly connected and of the other tab-shaped Part 17 or 16 has a predetermined distance, so that on this Side results in a slit-shaped opening 28.
  • the pin 27 is used for connection the switching shaft 9 with the circuit breaker of the circuit breaker, not shown 1, wherein a usually lever-shaped connecting part (toggle lever) of the key switch inserted into the gap-shaped opening 28 and by laterally shifting the pin 27 into a corresponding recess of the toggle lever is inserted.
  • the transition area between neighboring ones Druckkammem 3-5 is partly as a bearing 29 (Fig.1) for the bearing shaft 18 of the connecting the corresponding shaft segments 10-12 Coupling element 14, 15 formed (Fig.2, 3).
  • the invention is of course not limited to that described above Embodiment limited. So the circuit breaker according to the invention for example, also include four interrupters.
  • the shift shaft in this case is composed of four shaft segments, over three the coupling elements described above interconnected become.
  • the coupling elements can also be made of metal instead an electrically insulating material (e.g. plastic), provided that there is sufficient torsional rigidity of the selector shaft.
  • the pin 27 to connect the control shaft with the key switch can also be used as a continuous Be formed and the two tab-shaped parts 16th and 17 connect to one another without forming a gap-shaped opening 28. In this case, the toggle of the key switch is already pre-assembled on the Cones arranged.
