Housing for an electric device which needs to be earthed having a skin through which one or more screws pass compressing the surrounding skin material

摘要

The housing has a wall (1) comprising an electrically insulating fixed structure (3) and an electrically conductive skin (8) fastened to the structure. The housing also has an electrically conductive carrier (2) and at least one screw (17) which screws into a bore (7) of the structure (3) and holds the carrier pressed against the wall. The screw passes through a recess (13) in the skin and compresses the skin material surrounding the recess.
