Definitions

  • the invention relates to a switching device in a system of switching devices that can be coupled with switching or auxiliary switching or signal switching devices to be installed.
  • Such switching devices are on the market in the most varied of embodiments.
  • a multi-pole switch is constructed from single-pole circuit breakers in that the actuating handles are connected to one another by a rail-like bridge.
  • the handles In order to be able to compensate for tolerances when assembling, the handles have central recesses on their end faces, into which knobs engage with play in the longitudinal direction of the bridge. Sometimes one would like to avoid such specially adapted bridge elements, which have to be carried along for the assembly.
  • the invention has for its object to develop a system of switching devices that are to be coupled without coupling elements to be provided.
  • a coupling element made from a pair of the function of claw-shaped coupling element and peg-shaped coupling element is implemented on the roller body in the direction of the switching axis on a receiving side .
  • the coupling element which is movable behind a housing slot, the other coupling element of the functional pair can be brought into engagement, which is arranged in a housing slot on an outside of a device to be attached.
  • a claw-shaped coupling element for example, can be arranged on the roller body in the direction of the switching axis on a receiving side, with which a peg-shaped coupling element cooperates in a housing slot on the outside, which engages the claw-shaped coupling element on the receiving side of the receiving device from a device to be attached.
  • the claw-shaped coupling element is designed to have a claw tooth or a claw flank of the claw-shaped coupling element in the engagement depth only for a driver direction when the depth of penetration of a pin-shaped coupling element is less.
  • the switchgear to be installed remains unaffected when switched off by hand.
  • conditions can easily be met, such as are required between signal switches and circuit breakers of the type of the error signal switch.
  • Such a signal switch should only be switched on via the switching handle of the circuit breaker but no longer be able to be switched off.
  • the signal switch can only emit a signal if the circuit breaker has triggered in self-triggering.
  • a separate tripping coupling ensures that the signal switch is only switched off as intended in the event of an overload, be it overcurrent or a short circuit on the miniature circuit breaker.
  • the switching device 1 according to FIG. 1 has a roller-shaped manual control element 2, the switching handle 3 of which protrudes beyond the housing.
  • a claw-shaped coupling element 4 is arranged on the roller body in the direction of the switching axis on a receiving side behind the plane of the drawing. This is movable behind a housing slot 5 with its receptacle.
  • a peg-shaped coupling element 6 according to FIG. 3 is arranged in a housing slot on an outside. The peg-shaped coupling element engages deeply in the claw-shaped coupling element 4.
  • the pin-shaped coupling element 6 engages between the dog teeth 7 and 8 in the version 8.1.
  • the peg-shaped coupling element 6 is only available in a short version 6.2, it is single in this engagement depth Lich the flank of a single claw tooth 8.2, but no claw tooth on its other side.
  • a coupling is achieved for a long peg-shaped coupling element 6.1, as is desired for auxiliary switches, and a coupling as is desired for signal switches for a short peg-shaped coupling element 6.2. 1, both auxiliary switches and signal switches can be attached to the manual circuit breaker without additional coupling elements.
