Definitions

  • the invention relates to a contact element formed from a one-piece sheet metal blank by angling, with a contact slot which is set up for pressing a conductor into the slot and which has a closed end on one side, and with transverse to the plane of insulation displacement contact limbs which Limit contact slot, directed side walls placed parallel to the course of a conductor pressed into the contact slot, and with two tabs that are cut free from two opposing longitudinal side walls parallel to the course of the contact slot and with their free ends in the direction of the closed end of the contact slot are bent out of the long side walls.
  • Such a contact member is already known from FR-PS 24 54 191.
  • the two tabs cut free from the longitudinal side walls of the contact element are arranged like a trap in the direction of the closed end of the contacting slot.
  • a conductor which is pressed into the contact slot, first pushes the tabs apart with their free ends.
  • the tabs dig into the insulating jacket of the conductor.
  • the tabs can absorb tensile stresses acting on the conductor in the direction of the conductor and thus relieve the insulation displacement contact point of the contact element.
  • the object of the present invention is to make a contact element of the type mentioned at the outset even more adaptable in its effect on the absorption of tensile stresses even with conductors of different thicknesses.
  • this object is achieved in that a further tab which is bent out transversely to the contacting slot and is provided on the side of the closed end of the contacting slot and has its free end aligned with the contacting slot.
  • the tabs are provided at their free ends with a sawtooth-like configuration which is designed to be pressed into the insulation of a conductor pressed into the contact slot.
  • the longitudinal side walls are formed by the U-legs and the transverse side wall by the base of the U-shaped sheet metal blank and that the insulation displacement contact legs are part of a door-like section angled into the area of the U-contour are one of the two U-legs of the sheet metal blank.
  • the contact element 1 is formed from a one-piece sheet metal blank which is bent into a U-shaped configuration.
  • Two longitudinal side walls 3 face each other, which are connected to one another by a transverse side wall 4.
  • a section 5 of one of the two longitudinal side walls 3 is angled like a door into the region of the U-contour formed by the longitudinal side walls 3 and the transverse side wall 4.
  • a contact slot 6 is worked in symmetrically to the two longitudinal side walls 3, which is closed on the side of the transverse side wall 4.
  • the contacting slot is also open, so that from this side a conductor 2 with a course directed transversely to the slot 6 can be pressed into the slot 6.
  • the section 5 is also supported with its free end on an end face 7 of the other longitudinal side wall 3 which is not connected to the section 5.
  • a cut-out tab 8 is bent out of the transverse side wall 4 in such a way that it is aligned with the slot 6 and with its free end 9 protrudes slightly from the closed end 13 of the slot 6 into the slot area.
  • the conductor 2 pressed into the slot 6 is therefore when pressed also pressed against the free end 9 of the tab 8.
  • the free end 9 digs into the insulating sheath 14 of the conductor 2.
  • the tabs 8 and 11 are provided at their free ends with a sawtooth-like structure 15, which further increases the holding effect exerted on the conductor 2 by the tabs.
  • the tabs 11 can be dimensioned relatively long in the direction of the conductor 2, which further improves the holding effect of the tabs.
  • the insulation displacement contact limbs 16 delimiting the slot 6 are provided with bevels at their free ends in order to promote the penetration of the leg ends into the insulating jacket 14 of a conductor 2 to be pressed into the contact slot 6.
