Definitions

  • the invention relates to a device for establishing an electrical connection of an electrical installation device with one with insulation electrical conductor, which is provided in supply openings provided for this purpose Contact terminals of the electrical installation device introduced for contacting becomes.
  • the assembly work is due to the need to wire each conductor before Connection to stripping, hindered or delayed over time, because without this requirement, the assembly work could be done much faster respectively.
  • the insulation is stripped incorrectly explains the risk of damage to the conductor.
  • DE 44 03 507 C1 discloses a terminal contact device for areas Stripping an electrical wire and for making contact between the stripped wire area and the processing tool, such as one Knife known, the stripping of the electrical wire and contacting by moving the knife (peeling knife) in the direction of the Longitudinal axis of the wire takes place.
  • a favorable further development of the stripping device according to the invention proves is particularly advantageous in that at least two cutting blades are provided are whose cutting edge spacing is at most the smallest at rest Conductor cross-section of the conductor wire intended for assembly corresponds, wherein in further improvement of the invention at least one of the circular cutting blades is spring loaded.
  • These two cutting blades are preferably diametrically opposite one another arranged, but also a so-called star arrangement of the cutting blades be provided, which a migration of the conductor wire when removing the insulation largely prevented because the cutting blades automatically remove the conductor wire center and thus ensure its uniform application.
  • FIG. 1 shows a stripping device 10 according to the invention with two cutting blades 12, 14 shown from the insertion side in cross section, the die Cutting blades 12, 14, leading and supporting shafts 13, 15 in one to Stripping device 10 supporting scaffold 16, which in turn on the associated, here not shown base of the electrical installation device concerned is attached.
  • the two cutting blades 12, 14 of the stripping device 10 are, as from the in 2 side view shown rotated by 90 ° can be seen circularly shaped, the side surfaces of the cutting blades 12, 14 tapering are formed, as shown in Fig. 1, and so a rotating, that is Form all-round, razor-sharp cutting edge 18.
  • each of the two cutting blades 12, 14 penetrates into the insulation 20 of an electrical conductor 22 inserted into the stripping device 10 to Circumferential surface of the conductor wire 24 protected by the insulation 20, so that its insulation 20 can be easily lifted off the conductor wire 24.
  • FIG. 3 shows a basic illustration of a stripping device shown in FIGS. 1 and 2 10 and a contact terminal 26 formed with a peeling mandrel 28 Assembly unit shown in side view, in a relevant installation device is inserted.
  • the adjustability of the lower cutting blade 12 is provided here is also achieved here by means of springs, not shown, and by means of Double arrow appears.
  • a desired advantage of the present invention is that with the Insert the conductor end 22 to be connected into the insertion opening of the relevant one Installation device is immediately accompanied by the exposure of the conductor wire, so that neither an additional operation nor an additional tool is needed.
