Definitions

  • the connector according to the invention is particularly suitable for connection to a coaxial line or also to a so-called twin-axial line, which consists of two axially arranged conductors which are twisted together and an outer shield arranged above them.
  • twin-axial lines are e.g. used as data bus lines, particularly in aircraft construction, for example for connecting on-board computers or measuring systems to the associated computing units.
  • the metallic housing sleeve according to the invention is formed in one piece and accommodates the plug contact housing in the interior, a tight fit of the plug contact housing being achieved by a latching or counter-latching device which is formed in the interior of the housing sleeve or on the outside of the plug contact housing.
  • the latching device in the housing sleeve can be designed as a projection, the plug contact housing being provided with a corresponding recess. However, it is also possible to incorporate a recess in the housing sleeve and to form the projection on the plug contact housing.
  • the locking device can be formed at one point on the inner circumference of the housing sleeve, it can also extend in a ring on the inner circumference.
  • a spring ring projecting radially inwards is preferably formed in the inner wall, while the plug contact housing has a correspondingly designed circumferential groove on its outer circumference.
  • the plug contact housing is formed in one piece and serves to accommodate one or more plug contacts.
  • the plug contact housing has one opening per plug contact receiving opening, which opening extends transversely thereto and is suitable for the access of a crimping tool to the respective plug contact.
  • the area which is provided with the metal sleeve 11 has a reduced outer diameter compared to the rest of the plug contact housing 6, so that the outer diameter of this area with the metal sleeve 11 pushed onto the plug contact housing 6 and the screen 16 pushed over it is substantially equal to the outer diameter of the rest of the plug contact housing 6 is. If a cable 17 with two electrical conductors and an electrical shield 16 is now to be connected to the plug contact connector, the shield 16 is first removed from the end region of the two electrical conductors by pushing back and the two electrical conductors are inserted into the plug contacts 7 and with the aid of a Crimping tool that engages through the engagement openings 12 attached. The screen is then pulled over the metal sleeve 11. The plug contact housing 6 is thus connected to the electrical conductors of a cable and can now be pushed into the housing sleeve 1.
  • the twin-axial conductors are surrounded by the shield 16, which in turn is surrounded by an outer insulating jacket 29 of the cable 17.
  • the front end of the screen 16 is located between the metal sleeve 11 and the crimping zone 3 of the metallic housing 1.
