Definitions

  • the invention relates to a connecting device with a plug connector and a mating plug connector, in particular for connecting at least one cable to another electrical component.
  • Plug connector assemblies are generally used to detachably connect cables, in particular coaxial cables, to an electrical component.
  • Plug connector assemblies normally have contact parts that are connected to the conductive components of the cable in order to establish an electrical connection between the cable and the component to be connected.
  • a plug connector assembly typically has a housing part for each connection partner. The housing part is mechanically connected either to the component or the cable or to the contact parts.
  • the housing parts of the connection partners can be detachably connected to one another in order to create an additional connection which, on the one hand, protects the conductive connection of the contact parts and makes the connection of the connection partners more stable and resilient to external influences.
  • plug connector position lock may be necessary, which prevents the snap connection from being undesired or unintentionally released.
  • plug connector position locks are known, for example, from the documents US9054458 B1 , US10355414B1 and EN 11 2017 001 349 T5 known.
