Abstract (en)
[origin: DE19624920A1] Such contact arrangements usually consist of two opposite contact makers (1). In order to form a spiral contact, each contact maker (1) may have slots that extend outward from a centre. According to the invention, the contour of the slots (3-8) has a variable radius (r( phi )) whose foot coincides with the centre (10) of the contact maker (1) with a predetermined radius (RK). The slots preferably end at or slightly intersect a turned groove (2) with predetermined radius (RI) located at the centre of the contact maker (1), whereas RI SIMILAR 0.25 - 0.33 . RK. Specific mathematic functions may be given for the slot contours.
