Abstract

Der erfindungsgemässe Elektrodenhalter für eine mit Hochspannung betreibbare Pulversprühpistole umfasst ein Pulverkanal (10) und einen im Pulverkanal (10) angeordneten Steg (23) zum Halten einer Hochspannungselektrode (11). Zudem ist eine konzentrisch zum Pulverkanal (10) angeordnete Ringnut (13) vorgesehen, die auf der stromabwärtigen Seite offen ist. Die Ringnut (13) bildet mit einem in die Ringnut ragenden ringförmigen Steg (61) einer Überwurfmutter (6), welche zur Arretierung des Elektrodenhalters (9) dient, ein Labyrinth für die Hochspannung.
