  • the invention relates to a connecting element for connecting at least two switching devices.
  • the invention further relates to a switching device and an electrical distribution system.
  • Such a connecting element is used wherever at least two electromechanical devices (switching devices) are to be electrically and mechanically connected to each other.
  • the devices are mechanically connected directly by guide grooves.
  • the electrical connection is then made via a separate three-pin plug.
  • the switching devices are mechanically connected via an intermediate plate.
  • the intermediate plate is plugged onto the circuit breaker and electrically connected to the circuit breaker.
  • the electrical connection of the intermediate plate with the contactor is again achieved via a three-pole plug.
  • the invention has for its object to enable a fast and wireless connection of several electromechanical devices.
  • connection element the mechanical and electrical connection of the switching devices without wiring.
  • connection element plug

It can be bent by the flexible design of each connection element for - independently - and thus achieve the tolerance compensation.
  • the connecting element according to the invention it is also possible to halve the high insertion forces by first connecting the connector to a switching device, e.g. a contactor is plugged and then the connector with the contactor to another switching device, e.g. a circuit breaker is plugged. Since both the mechanical and the electrical connection is achieved with a connector, the number of required connection parts is reduced. In addition, only one connection process is necessary in order to contact the connection means of the switching devices and to create a mechanical connection.
  • a switching device e.g. a contactor is plugged
  • another switching device e.g. a circuit breaker
  • connection elements are designed as conductive pins. These so-called pins are for engaging in the contact openings of Switchgear provided.
  • the connecting element has ever to connecting switching device on three pins, which can also be implemented as a connected pin headers, making this very well suited for the standard switching devices such as circuit breakers and contactors.
  • the conductive pins on a plastic sheath As a result, the security is increased in particular in situations in which the connector is only connected to a switching device and possibly not yet connected to a switching device connecting elements are connected to current-carrying lines.
  • the plastic sheath is designed to be flexible and / or finger-like.
  • the flexibility of the connecting elements is supported, in particular a finger-like design allows tolerance compensation in all three spatial directions.

  • the mechanical guidance can provide better protection for electrical contacting against bending or twisting, i.
