Method for ensuring the electrical shielding of a device housing

A method for ensuring electrical shielding of a device housing during processing, which the device housing comprises a hollow profile that is closed on a front side by at least one housing cover, wherein both the hollow profile and the housing cover are electrically conductive, the method comprising:

• providing the housing cover comprising, as a cover edge, an annular extension which projects from a cover side and encompasses an overlapping region (d) of a section at an end of the hollow profile, which section is thinned from an exterior, wherein a selected height (h) of the annular extension is less than the height (H) of the thinned section,
• adjoining the housing cover to the hollow profile such that the front side of the thinned section adjoins the cover interior in a contacting manner, and a distance (a) remains between a free end of the annular extension and a ledge at a beginning of the thinned section of the hollow profile,
• providing a processing cover that is used for processing the device housing and also comprises a annular extension which, in a processing position, encompasses the thinned section of the hollow profile and adjoins the thinned section of the hollow profile, wherein the selected height (h h2) of the annular extension of the processing cover is greater than the height (H) of the thinned section so that, during processing, said extension adjoins the ledge at the beginning of the thinned section of the hollow profile.
