Abstract

In a method for secondarily locking at least one electrical contact (2) which is inserted into a contact chamber (7) and is primarily latched therein, the at least one electrical contact (2) is, according to the invention, primarily latched in its contact chamber (7) by means of an external latching tool (12) which engages in the contact chamber (7) through a lateral wall opening (11) in the contact chamber outer wall (10) from outside, and the electrical contact (2) is then secondarily locked in its contact chamber (7) before the external latching tool (12) is removed again. The associated contact latching system for an electrical plug connection comprises at least one electrical contact (2) which has an undercut (6) for a primary latching means, a contact chamber housing (1) which has at least one contact chamber (7) for insertion of the electrical contact (2), and at least one locking element (17) for secondarily locking the inserted electrical contact (2) against the fitting direction (3), wherein, according to the invention, a contact chamber outer wall (10) of the contact chamber (7) has a lateral wall opening (11) through which the undercut (6) in the inserted contact (2) is accessible from the outside.

Verfahren und Kontaktverrastungssystem zur temporären Primärverrastung von elektrischen Kontakten in Steckverbindungen  Method and contact latching system for temporary primary locking of electrical contacts in connectors
Die Erfindung geht aus von einem Verfahren zum Sekundärverriegeln The invention is based on a method for secondary locking
mindestens eines in einer Kontaktkammer primärverrasteten elektrischen Kontakts nach der Gattung des Anspruchs 1 sowie von einem zugehörigen Kontaktverrastungssystem nach der Gattung des Anspruchs 3. at least one primary contact in a contact chamber electrical contact according to the preamble of claim 1 and of an associated Kontaktverrastungssystem according to the preamble of claim 3.
Derzeit werden im Automotive-Bereich elektrische Stecksysteme eingesetzt, bei denen die elektrischen Kontakte an elektrischen Leitungen angeschlagen (angecrimpt) und anschließend einzeln in Kontaktkammern eines At present, in the automotive sector electrical plug-in systems are used, in which the electrical contacts are struck (crimped) on electrical lines and then individually in contact chambers of a
Kontaktkammergehäuses (Kontaktträger) eingeschoben werden. Am Ende des Bestückungsweges verrasten die Kontakte in den Kontaktkammern der Contact chamber housing (contact carrier) are inserted. At the end of the assembly process, the contacts in the contact chambers of the
Kontaktträger. Diese sogenannte Primärverrastung erfolgt beispielsweise durch federnde Metallzungen der Kontakte, die einen Absatz der Kontaktkammern entgegen der Bestückungsrichtung hintergreifen, oder durch federnde Elemente der Kontaktkammern, die in entsprechende Aussparungen der Kontakte einrasten. Auf diese Weise wird verhindert, dass die Kontakte an ihren  Contact support. This so-called Primärverrastung done for example by resilient metal tongues of the contacts which engage behind a shoulder of the contact chambers against the loading direction, or by resilient elements of the contact chambers, which engage in corresponding recesses of the contacts. This will prevent the contacts from being attached to theirs
Leitungen unbeabsichtigt aus den einmal erreichten Endpositionen wieder zurückgezogen werden können. Zur Abfrage und Sicherstellung der korrekten Einstecktiefe der Kontakte wird am Ende der Bestückung die sogenannte Sekundärverriegelung geschlossen, durch die alle eingesteckten Kontakte entgegen der Bestückungsrichtung verriegelt sind. Ab diesem Zeitpunkt ist die Primärverrastung quasi überflüssig, da die von der Sekundärverriegelung bereitgestellte Haltesicherheit bzw. Haltekraft in der Regel die der Lines can be inadvertently withdrawn from the once reached end positions again. To query and ensure the correct insertion depth of the contacts so-called secondary locking is closed at the end of the assembly, are locked by the all inserted contacts against the loading direction. From this point, the Primärverrastung is virtually superfluous, as provided by the secondary locking holding security or holding force usually the

Retaining safety or holding force significantly exceeds the primary locking. As shown in Fig. 2, the minimum possible row spacing (pitch) A 'of the two rows of contact chambers and thus the minimum possible width B' of the contact chamber housing 101 are predetermined by the partition wall width C, which in turn required by the required for the primary detent deflection of the latching arms is predetermined.
