Beschreibung der Ausführungsbeispiele Das in Fig. 1 gezeigte Kontaktelement 1 dient zur elektrischen Direktkontaktierung einer Gegenkontaktfläche, insbesondere einer Description of the embodiments The contact element 1 shown in FIG. 1 is used for direct electrical contacting of a mating contact surface, in particular one

Kontaktfläche („Land") auf einer Leiterplatte. Das Kontaktelement 1 wird üblicherweise in ein Kontaktgehäuse, z.B. eines Kabelbaumsteckers, eingesteckt und wegen der Kontaktierung direkt auf die Leiterplatte auch als Direktsteckkontakt bezeichnet. The contact element 1 is usually plugged into a contact housing, for example a harness connector, and is also referred to as a direct plug-in contact because of the contacting directly on the printed circuit board.

Das Kontaktelement 1 umfasst einen hinteren Anschlussabschnitt 2 zum Anschließen (z.B. Crimpen) einer elektrischen Leitung 3 eines Kabelbaums (Kabelstrangs), einen vorderen Kontaktabschnitt 4 und einen zwischen dem Anschluss- und dem Kontaktabschnitt 2, 4 vorgesehenen, im Querschnitt U- förmigen Steckabschnitt 5 zum Einstecken, Führen und Verriegeln des The contact element 1 comprises a rear connection section 2 for connecting (eg crimping) an electrical line 3 of a cable harness (wiring harness), a front contact section 4 and a provided between the terminal and the contact section 2, 4 in cross-section U-shaped plug portion 5 to Inserting, guiding and locking the
