Abstract

Eine Rasteinrichtung (16) für ein Pumpengehäuse (12) zur Herstellung einer lösbaren Rastverbindung zwischen zwei Gehäuseteilen (13,14) weist an einem ersten Gehäuseteil (13) einen länglichen Rasthaken (19) auf mit einem Rastvorsprung (20) an der Oberseite und Einführschrägen (23,24) an Oberseite und Unterseite. Am zweiten Gehäuseteil (14) ist eine Rastöffnung (30) vorgesehen mit einer die Rastöffnung (30) nach außen begrenzenden Rastlasche (31), an der der Rastvorsprung (20) anliegt. An der Unterseite der Rastöffnung (30) ist ein Einführsteg (36) mit einer Einführschräge (37) für den Rasthaken (19) angeordnet. Zwei Sicherungslaschen (40) greifen seitlich in die Rastöffnung (30) ein und ragen mit einem freien Laschenende (41) in den Weg des Rasthakens (19) beim Einstecken in die Rastöffnung (30). Sie verhindern ein ungewolltes selbsttätiges Lösen der Rastverbindung durch Bewegen des Rasthakens (19) nach unten.

A latching device (16) for a pump housing (12) for producing a releasable latching connection between two housing parts (13, 14) has on a first housing part (13) an elongate latching hook (19) with a latching projection (20) on the top side and insertion bevels (23,24) on top and bottom. On the second housing part (14) has a latching opening (30) is provided with a latching opening (30) outwardly delimiting latching tab (31) against which the latching projection (20). On the underside of the latching opening (30), an insertion web (36) with an insertion bevel (37) for the latching hook (19) is arranged. Two securing tabs (40) engage laterally in the latching opening (30) and protrude with a free tab end (41) in the path of the latching hook (19) when inserted into the latching opening (30). They prevent unwanted automatic release of the latching connection by moving the latching hook (19) down.
