Definitions

  • the present invention relates to a contact screw for the conductor wire of a shielded cable, in particular the data transmission wire of a flat cable having a plurality of conductor wires, which screw is intended to be moved axially in a connecting device by means of a thread and has a shaft with a screw thread and a contact tip, the section of the contact tip provided for penetrating the cable insulation and the shield is provided with a covering of insulating material.
  • FIG. 1 shows a side view of the contact tip end of a contact screw according to the invention
  • Fig. 2 is a view similar to Fig. 1 with the insulating sleeve, and
  • Fig. 3 and Fig. 4 schematically the operation of contact screws.
  • FIG. 1 and 2 shows the lower part of a metal contact screw with shaft 1 and contact tip 2 with mushroom-shaped end 2 '.
  • a Screw thread 3 is provided with a predetermined pitch (for example 0.7 mm), via which the screw can be moved axially in a threaded bore of a connecting device (not shown).
  • a predetermined pitch for example 0.7 mm
  • Contact tip 2 is a sleeve 4 made of insulating material.
  • the sleeve 4 like the contact tip 2, tapers towards the end 2 'and lies between the shoulders 1' of the shaft end and 2 '' of the mushroom-shaped end 2 '.
  • the conical shape of the insulating sleeve 4 increases the pressure between the flanks of the contact tip 2 of the screw and the insulating material of the cable, thus further improving the dielectric strength.
  • the mushroom-like shape of the end 2 'of the contact tip 2 protects the insulating sleeve 4, as a result of which the penetration force is transmitted from the metal part and no longer through the insulating sleeve.
  • Fig. 3 of the drawing shows a purely schematic contact screw according to the prior art. It is clearly visible how the screen 10 is pressed closer to the conductor 20 at the penetration point. 4 shows the solution according to the invention. It is clearly visible how, thanks to the external thread 5, with a larger pitch than the screw thread 3, both the insulation and the shield 10 at the penetration point are moved away from the conductor 20 on the insulating sleeve 4.
