Eine derartige Anzahl von Federarmen hat sich als besonders vorteilhaft herausgestellt. Sind mehr Federarme vorhanden, werden die Federelemente - und damit der gesamte Buchsenkontakt - mechanisch instabil. Die Federarme verformen sich beim Einstecken des Stiftkontaktes leicht und eine Preferably, three axial slots are introduced into the hollow cylinder, whereby a total of six spring arms are formed. Such a number of spring arms has been found to be particularly advantageous. Are more spring arms present, the spring elements - and thus the entire socket contact - mechanically unstable. The spring arms deform slightly when inserting the pin contact and a

Eine Buchse mit erfindungsgemäßen Federarmen hat die doppelte Anzahl von Berührkontakten mit einem eingesteckten Kontaktstift wie eine herkömmliche Buchse. Die Kontaktkraft zwischen Federarmen und A socket with spring arms according to the invention has twice the number of touch contacts with an inserted contact pin as a conventional socket. The contact force between spring arms and

Ein Verfahren zur Herstellung eines oben beschriebenen Buchsenkontakts verläuft folgendermaßen: Aus einem zylinderförmigen Grundkörper aus Vollmaterial wird im Zusammenspiel eines Hinterdrehverfahrens und eines Taumelverfahrens Material aus dem Grundkörper entnommen. Hinzu kommen so genannte Stoß- und Räumarbeitsschritte. Entscheiden ist, dass im Kontaktbereich des Federarms weniger Material abgetragen wird als außerhalb des Kontaktbereichs. In den so bearbeitenden Grundkörper wird zumindest ein, vorzugsweise jedoch drei, axialer Schlitz eingebracht, wodurch die einzelnen Lamellen gebildet werden. Das Verfahren wird so ausgeführt, dass der Federarm im Kontaktbereich eine größere A method for producing a socket contact described above proceeds as follows: From a cylindrical base body made of solid material in the interaction of a spin-turning method and a tumbling process material is removed from the body. In addition, there are so-called shock and Räumarbeitsschritte. Decide that less material is removed in the contact area of the spring arm than outside the contact area. At least one, but preferably three, axial slot is introduced into the base body thus machined, whereby the individual lamellae are formed. The procedure is carried out so that the spring arm in the contact area a larger

In den verschiedenen Ebenen liegen die Punkte auf einer gemeinsamen axialen Achse des Federarms. Diese axiale Achse wird in dieser Anmeldung auch als Krümmungsachse bezeichnet. Die zwei Berührkontakte zwischen Federarm und Kontaktstift liegen dann links und rechts von dieser Achse, aber keinesfalls darauf. formed to have a point in the circumferential direction whose radius of curvature is smaller than the radius of curvature of the points on the same plane. In the various planes, the points lie on a common axial axis of the spring arm. This axial axis is referred to in this application as the axis of curvature. The two Berührkontakte between spring arm and contact pin are then left and right of this axis, but not on it.
Besonders vorteilhaft weist der Kontaktbereich zumindest zwei Punkte auf, deren Krümmungsradien kleiner sind als der Radius des einzuführenden Stiftkontaktes. Diese zwei Punkte bilden die Berührkontakte zwischen Federarm und Kontaktstift. Im Endbereich eines jeden Federarms befindet sich ein so genannter Kontaktbereich. In diesem Kontaktbereich werden zwei Berührkontakte mit einem eingestecktem Stiftkontakt ausgebildet. Particularly advantageously, the contact region has at least two points whose radii of curvature are smaller than the radius of the pin contact to be inserted.

Dadurch können die physikalischen Eigenschaften der einzelnen Federarme, beispielsweise die Federkonstante, gezielt eingestellt werden. Advantageously, the wall thickness of the spring arms varies in the axial direction. This can be easily realized via the manufacturing process described above. As a result, the physical properties of the individual spring arms, for example the spring constant, can be set in a targeted manner.
