  • the plug 30 is shown.
  • the plug 30 is provided with a sensor or the like. to be connected.
  • the plug 30 is formed substantially rotationally symmetrical.
  • the plug 30 has a shield consisting of a first sleeve 31 and a second sleeve 32.
  • the first sleeve 31 has at its second sleeve 32 facing the free end an inner diameter corresponding to the outer diameter of the facing free end of the second sleeve 32.
  • the first sleeve 31 and the second sleeve 32 are pressed together at these mutually facing free ends (46). There is thus a firm mechanical connection between the first sleeve 31 and the second sleeve 32.
  • the first sleeve 31 is tubular. Inside the first sleeve 31, a contact carrier 33 is arranged. The contact carrier 33 serves to receive contact pins 34.
  • the first sleeve 31 is, for example, manufactured as a turned part of an electrically conductive metal.
  • the second sleeve 32 is made of plastic as an injection molded part.
  • the outer surface of the second sleeve 32 is provided with an electrically conductive layer 47.
  • the second sleeve 32 has a longitudinally aligned slot 35. Furthermore, the second sleeve 32 is provided with at least one window 36.
