Definitions

  • the invention relates to a contact device with a polytropic air gap - abbreviated LSA-PLUS contact - for soldering, screwing and stripping-free connection of an insulated, in particular aluminum or multi-wire copper conductor in the slot of a fixed connection element.
  • connection technology for soldering, screwing and stripping-free connection of conductor wires to terminal contacts, which has meanwhile found widespread use in technology under the name LSA-PLUS connection technology.
  • the spring tongues are offset from one another by deformation so that when the conductor wire is pressed in, the relatively sharp edges of the spring tongues delimiting the contact slot first cut the insulation and then penetrate the conductor material by a predetermined amount and in this way bring about the electrically conductive contact.
  • connection element of the type mentioned above and described in DE-PS 2610461 is that not every conductor wire is easy to connect.
  • connection element So z. B. aluminum wires or stranded copper conductors (stranded wire) with this connection element not easily connected.
  • the invention is therefore based on the object, using the LSA-PLUS technology, to provide a contact device for conductor wires, in particular also for aluminum and multi-wire copper conductors, which ensures perfect contact and is able to accommodate different wire diameters which can be used in the LSA Terminal strips can be used and in which the tools previously used for pushing in or pulling out the conductor wire should also be advantageously applicable.
  • connection element with a contact slot
  • air gap of which adapts automatically (for example in the event of aging of the conductor material) and always ensures sufficient contact pressure.
  • the subject matter of the invention is a device for producing a solder-free, screw-free and stripping-free contact with a polytropic air gap between a connecting element made of leaf-shaped, resilient contact material and a conductor wire to be connected in its slot, with the characteristic that the one-piece connecting element with an X-shaped cross section or made up of two hook-shaped parts and the conductor wire, in particular aluminum or multi-wire copper conductor, via two insertion openings, each of which has two essentially V-shaped centering areas and two offset cutting tips at their lower ends, which serve to tear open the wire insulation at staggered and opposite locations, can be inserted centrally into the slot, the wire diameter of the conductor wire to be connected, the width of the slot and the resilient slot walls determining the contact pressure.
  • conductor wires with different wire diameters can be easily connected, even if it is aluminum or multi-wire copper conductors.
  • the cutting tips preferably form a wedge space between them.
  • the width of the slot can be adapted to the wire diameter of the conductor wire, that the size of the contact area between slot walls and conductor wire can be selected as desired, that the connecting element consists of two v-cross-sectional parts which are firmly connected to one another by a connecting part are, or that it is alternatively made up of two hook-shaped parts.
  • Fig. 1 shows that the one-piece connecting element 1 for connecting conductor wires 2, in particular aluminum and multi-wire copper conductors, is formed in an X-shaped cross section.
  • the rear insertion opening 4 is shown in Fig. 2.
  • This insertion opening 4 like the insertion opening 3, has two essentially V-shaped centering regions 5, 6 which center the conductor wire 2 on two cutting tips 7, 8, which are molded onto the lower end of the centering region 6, guide.
  • the cutting tips 7, 8 are arranged offset, so that the wire insulation is torn open before the conductor wire 2 reaches the slot 10.
  • the two cutting tips 7, 8 form a wedge space 11 with respect to one another, which facilitates the cutting process.
  • 3 shows the representation of the lead wire 2 inserted into the slot 10; the slit walls 10a, 10b are pressed elastically against the wire core.
  • the slot width and the resilient slot walls 10a, 10b determine the contact pressure: if larger wire diameters are used, the contact pressure also increases.
  • the contacting area can be enlarged as desired using wider cutting tips 7, 8.
  • the insertion process of the conductor wire 2 can, for. B. be ended by the stop 12, which is a transverse part of the connecting element 1 here.
  • the connecting element 1 is also possible for the connecting element 1 to be constructed from two v-shaped parts 14, 15, which are firmly connected to one another by a connecting part (not shown),
  • FIGS. 4 and 5 Another embodiment is shown in FIGS. 4 and 5.
  • the connecting element 1 here consists of two hook-shaped parts 16, 17.
  • the width of the cutting tips 7, 8 determines the size of the contact surface.
  • the connecting element 1 itself can be used in both embodiments in the conventional LSA-PLUS terminal block 13, which is indicated in FIGS. 1 and 5.
  • the known push-in and pulling tools of the LSA system can also be used here.
