Definitions

  • the invention relates to a device for the electrically conductive connection of an insulated cable core to an upright contact element, consisting of a plunger arranged longitudinally displaceably in a housing and having a pressure piece at its front free end.
  • the invention is particularly applicable in the field of telecommunications, specifically for the soldering, screwing and stripping-free wiring of telephony systems.
  • contact elements fastened upright in a carrier which have at least one longitudinal slot of a predetermined length, the width of which is somewhat less than the diameter of the conductor wire.
  • One end of the wire is pressed transversely into this slot, the slot boundaries which are resiliently deformable to a predetermined extent being laterally displaced such that their sharp edges cut through the insulation and penetrate the wire material to a predetermined extent.
  • the object of the invention is to provide a device of the type mentioned at the beginning with which electrically conductive clamp connections between cable cores and upright, laterally unsupported connecting elements can be produced safely and in a simple manner.
  • a sleeve surrounding the plunger at least over part of its length is arranged in the housing, the free, longitudinally slotted end of which protrudes beyond the pressure piece and laterally supports the tongues of the contact element before and during the clamping process.
  • the front end part of the pressure piece is also designed such that the side surfaces of two profiled longitudinal webs delimiting an oblique central slot lie against the corresponding side surfaces of the contact part of the connection element.
  • the pressure piece displaceable in the sleeve has an oblique slot, which fixes the middle, longitudinally slotted contact part of the contact element on both sides, between two profile webs.
  • part of the sleeve wall is designed as a cutting edge which, after clamping, separates the cable end by a further advancing movement of the device together with a cutting edge formed on the pressure piece.
  • the device shown in FIGS. 1 and 2 consists of a gradually tapering plunger 1, which is supported with its rear thickened end part on a coil spring 4 arranged in a cavity of a housing 5.
  • the front and middle parts of the plunger 1 are guided in a longitudinally displaceable manner in a sleeve 2.
  • a pressure piece 1 a is also formed which, as can be seen in FIG. 2, delimits one of two profile webs 1 b has oblique longitudinal slot 1c.
  • the front end of the sleeve 2 fixed with its widened rear part 2 in the housing 5 protrudes beyond the end edge of the pressure piece 1 a in the position shown in FIG. 1.
  • a cutting edge 3a is formed in this front end of the sleeve, which is opposite a longitudinal slot 3b of greater length. This cutting edge 3a interacts with a cutting edge provided on the pressure piece 1a or at its transition to the plunger 1.
  • the sleeve 3 encloses a connection element 11 which has a Z-shaped cross section before and during the actual clamping process.
  • a connection element 11 which has a Z-shaped cross section before and during the actual clamping process.
  • each leg 13 of this connecting element 11 there is a longitudinal slot 13a of a predetermined length (see FIGS. 3a, 3b), the rounded bottom of which forms the abutment for the insulation of the cable core in the fully pressed-in state.
  • the middle part of the Z-shaped connecting element represents the actual contact element 12 and has a longitudinal slot 12a of greater length, which has a greater width in its lower part 12b to achieve a spring action of two tongues 12c cutting into the wire material.
  • a further feed movement of the housing 5 causes the sleeve to advance further relative to the plunger 1 and the pressure piece 1a, so that the cutting edges come into effect and cut off a projecting end of the cable core transversely at a predetermined distance. This completes the connection process and the device can be removed.
