Pre-insulation of components for assemblies enclosed by housing element, comprises connecting components to pole of direct current source, and immersing components in paint bath connected to another pole of direct current source

摘要

The method for pre-insulation of components (1) for assemblies that are enclosed by a housing element using an electrochemical dip lacquering method, comprises connecting the components to a pole of a direct current (DC) source (5), immersing the components in a paint bath (31) connected to another pole of the DC source, and depositing a resist layer as a pre-insulation layer (32) on free metal conductor elements (11) of the components. The free metal conductor elements of the components are connected to a cathode as one pole, and the paint bath is connected to an anode as the other pole. The method for pre-insulation of components (1) for assemblies that are enclosed by a housing element using an electrochemical dip lacquering method, comprises connecting the components to a pole of a direct current (DC) source (5), immersing the components in a paint bath (31) connected to another pole of the DC source, and depositing a resist layer as a pre-insulation layer (32) on free metal conductor elements (11) of the components. The free metal conductor elements of the components are connected to a cathode as one pole, and the paint bath is connected to an anode as the other pole. The components are: partially reshaped with the housing element after coating with the pre-insulation layer; and fitted with construction elements after coating with the pre-insulation layer. A binder (10-30 wt.%) based on the total amount of the paint bath, 6 wt.% of body conductivity based on a solid content of the binder, and 0.1-0.8 wt.% of acids based on the total amount of the paint bath are used in the cathodic dip lacquering. An independent claim is included for a component for assemblies.
