  • the connection plate is not necessarily a plate-shaped element with a large expansion. Rather, more compact connection constructions, which enable the connection plug to be inserted and fixed, are subsumed under the term connection plate.
  • the connection plate is, for example, permanently connected to a machine frame.
  • the connecting pawl can be mounted by means of a bolt which is aligned parallel to the longitudinal axis of the connection units, ie vertically in a typical installation situation.
