  • the airbag connector must transmit a triggering signal to the airbag igniter with absolute reliability and, on the other hand, electrical interference signals, e.g. B. be triggered due to voltage peaks in the vehicle electronics, trigger no unintentional ignition of the airbag.
  • Connectors that are designed for use in airbag ignition systems must be compact and space-saving, since there is very little space when they are used in the steering wheel of a motor vehicle. Furthermore, these plug connectors must provide space inside for filters that are intended to prevent electromagnetic interference from leading to an unintentional triggering of the ignition system, for example ferrite cores, so-called ferrite core chokes.
  • filters that are intended to prevent electromagnetic interference from leading to an unintentional triggering of the ignition system, for example ferrite cores, so-called ferrite core chokes.

  • This is achieved by forming the sleeve from a substantially incompressible material. With such an incompressible material, the sleeve can no longer be pushed into the receiving opening while being pressed and overlapped, as is the case with an embodiment made of elastic material, but a type of sliding fit is to be provided for the bearing.
