Herstellungskosten des Kontaktelements reduziert werden. Durch Entfall der Kontaktfeder reduziert sich auch die bisherige Abhängigkeit der Manufacturing costs of the contact element can be reduced. By eliminating the contact spring also reduces the previous dependence of
Kontaktnormalkraft von der Kontaktfeder, denn insbesondere bei Contact normal force of the contact spring, especially at
miniaturisierten Kontaktelementen wird es mit steigendem miniaturized contact elements will increase with it
Miniaturisierungsgrad schwierig, die geforderten Kontaktnormalkräfte noch zu erreichen. Die Kontaktnormalkraft wird erfindungsgemäß durch die  Miniaturization degree difficult to reach the required contact normal forces yet. The contact normal force is inventively by the
Anpressfedern entweder direkt oder über bewegliche Anlageelemente des Kontaktträgers individuell auf jedes Kontaktelement aufgebracht. Die Pressing springs either directly or via movable contact elements of the Contact carrier individually applied to each contact element. The
Anpressfedern können dabei vorteilhafterweise als Einzelfedern ausgebildet oder aber durch einen einteiligen Federkamm gebildet sein. Da Anpressfedern can advantageously be formed as individual springs or be formed by a one-piece spring comb. There
Leiterplattentoleranzen nun über die individuell wirkenden Anpressfedern ausgeglichen werden können, kann der Kontaktträger statt weiterhin zweiteilig erfindungsgemäß nun auch einteilig ausgeführt werden, was zu einer weiteren Kostenreduzierung führt. PCB tolerances can now be compensated by the individually acting pressure springs, the contact carrier instead of two-piece according to the invention can now also be made in one piece, resulting in a further cost reduction.
Die beweglichen Anlageelemente des Kontaktträgers können zusätzlich auch die Funktion einer Kontaktprimärverrastung übernehmen, um die in den Kontaktträger eingesteckten Kontaktelemente darin entgegen ihrer The movable contact elements of the contact carrier can also take over the function of a Kontaktprimärverrastung to the inserted into the contact carrier contact elements therein against her
