Abstract

Um eine sehr kleine und kompakte Ausführungsform eines Kupplungssteckers 1, insbesondere zur Verwendung für eine planaren Breitband-Lambdasonde mit einer Abgleicheinheit 6 zu ermöglichen, wird vorgeschlagen, einem Kupplungsstecker nach folgenden Merkmalen auszubilden:

  • Kupplungsstecker (1), insbesondere für eine planare Lambda-Sonde, bestehend aus einem Gehäuse (2), nämlich einem Grundkörper (3) und einem Dekkelelement (4) sowie elektrischen Bauteilen, die in das Gehäuse einlegbar und fixierbar sind, und einem Abgleichelement (6) für eine Sonde, insbesondere eine planare Breitband-Lambdasonde, die in dem Kupplungsstecker (1) oder über ein weiteres Kontaktelement ausserhalb des Kupplungsstekkers anzubringen ist, wobei das Deckelelement (4) über der Abgleicheinheit (6) aufsteckbar ist und eine Primär- und eine mit dem Deckelement (4) zusammenwirkende Sekundärverriegelung aufweist, und die Sekundärverriegelung als Fixierelement (12) zum Fixieren mindestens eines in dem Gehäuse (2) eingelegten elektrischen Kontaktes (13) vorgesehen ist und dieses Fixierelement (12) zusätzlich zum Deckelelement (4) hinweisende Stützelemente (11) aufweist in der Art, dass nur in der Endstellung der Sekundärverriegelung das Deckelelement (4) vollständig schliesst, wobei mindestens eines der freien Enden der Stützelemente (11) von der Längserstreckung der Stützelemente (11) wegweisende Kontrollelemente (20) aufweist, die derart ausgebildet sind, dass in einer ersten Stellung des Fixierelements (12) dieses in Richtung des Grundkörpers (3) nicht, in einer weiteren Stellung von einer definierten Lage in eine Endstellung verschiebbar ist.

    In order to enable a very small and compact embodiment of a coupling plug 1, in particular for use for a planar broadband lambda probe with an adjustment unit 6, it is proposed to design a coupling plug according to the following features:
  • Coupling plug (1), in particular for a planar lambda probe, consisting of a housing (2), namely a base body (3) and a cover element (4) and electrical components, which can be inserted and fixed in the housing, and a balancing element ( 6) for a probe, in particular a planar broadband lambda probe, which is to be mounted in the coupling plug (1) or via a further contact element outside of the coupling plug, wherein the cover element (4) via the balancing unit (6) can be plugged and a primary and a secondary lock cooperating with the cover element (4), and the secondary lock as fixing element (12) for fixing at least one in the housing (2) inserted electrical contact (13) is provided and this fixing element (12) in addition to the cover element (4) indicative Supporting elements (11) in such a way that only in the end position of the secondary locking the cover element (4) completely schl wherein at least one of the free ends of the support elements (11) of the longitudinal extension of the support elements (11) pioneering control elements (20) which are formed such that in a first position of the fixing element (12) in the direction of the base body (3 ), in a further position from a defined position into an end position is displaceable.
