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.

Figure imgaf001
The electrode holder according to the invention for a high-voltage powder spray gun comprises a powder channel (10) and a web (23) arranged in the powder channel (10) for holding a high-voltage electrode (11). In addition, a concentric with the powder channel (10) arranged annular groove (13) is provided, which is open on the downstream side. The annular groove (13) forms with a protruding into the annular groove annular ridge (61) of a union nut (6), which serves to lock the electrode holder (9), a labyrinth for the high voltage.
