Definitions

the invention relates to a method and an apparatus for producing a electrical connection of an electrical installation device with one with one Insulation provided electrical conductor, which is intended for this purpose, with feed openings provided contact terminals of the electrical installation device for Contacting is introduced.
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 one with the assembly of the concerned Installation device concerned person no longer a multiple tool change make the sum of the time required for the individual assemblies not insignificant. This also removes the need for attention and, if necessary required control of the tool in comparison with the relevant one Conductor cross-section, since according to the invention depending on the respective conductor wire integrated for stripping according to the invention in the installation device in question Stripping device adjusts itself to the respective conductor cross-section, see above that on the one hand it is guaranteed that the insulation is actually before the Contacting in the associated contact terminal is removed and that on the other hand also no damage to the conductor wire, for example due to crushing or partial separation.
insulation when inserting the electrical conductor into the feed opening first cut open along at least one line on the circumference. Subsequently is accompanied by the insertion movement of the conductor The insulation is lifted off the conductor wire and the bare conductor wire is inserted into the Contact clamp inserted.
the slicing is a further improvement of the method according to the invention insulation with the insertion movement of the electrical conductor into the feed opening hand in hand. This is what is required to cut open the insulation Force due to the insertion force required to insert the conductor into the contact gill applied, this force being at most 35 N.
a device for carrying out the method explained above, intended for an electrical installation device, such as Switches, buttons, sockets, with a base, in / on which contact terminals are arranged are, which are each provided with an insertion opening, in each of which electrical conductors provided with external insulation for the electrical connection of the installation device are insertable, characterized in that each contact terminal is assigned a stripping device, which during insertion of a cable to be connected automatically into the assigned contact terminal its insulation removed so that the bare conductor wire engages in the insertion opening.
the stripping device is disc-shaped Blades formed with cutting edges, the plane of extension parallel to one another and is aligned radially to the conductor wire to be stripped.
the disk-shaped blades are rotating circular disks formed with cutting edges provided on its circumference, which in the Penetrate the insulation of the conductor in question radially up to the conductor wire surface.
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 block the conductor wire center automatically 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.
