Problems solved by technology

However, it is difficult to achieve the required operational security for such a connection, since the panels must be very soft or very thin for the screw to be able to cut the thread without applying a disproportionate torque to the screw, thereby compromising the Only a small load can be applied on the connection of the

Embodiment Construction

[0019] Figure 1 shows an exploded perspective view of the connection between a housing wall 1 of a refrigerator and a support rail 2 used as a support for a compressor (not shown) of the refrigerator.

[0020] The partially drawn housing wall 1 comprises an inner part 3 made of plastic and an outer part 8 made of enamelled metal. The inner part 3 comprises a plate 4 forming the inner side of the housing wall and a U-shaped piece 5 formed at the free edge of the plate. Molded in the groove of the U-shaped piece 5 in the perspective view of Figure 1 are a plurality of block plastic bodies 6 which connect the opposing wings of the U-shaped piece 5 to each other and form a small hole7.

[0021] The outer part 8 of the housing wall 1 comprises a plate 9 parallel to the wall plate 4 of the inner part 3 and a first bar 10 bent at a right angle and a second bar 11 inclined from the edge of the first bar 10 parallel to the plate 9 . When the parts are assembled, the first rod 10 cove...

Abstract

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.

Description

technical field [0001] The invention relates to an electric appliance housing, in particular to the grounding of the housing components. Background technique [0002] In order to ensure safe operation of electrical appliances, metal parts that are in contact with the user and that conduct electricity when the appliance is in use must be grounded, or metal parts that may be conductive due to a fault must be grounded. For blank metal parts, grounding can be achieved by pressing the parts, such as screwing them tightly, to a grounding conductor. Such ground conductors are for example wires which are connected to the ground potential of an AC power socket, or conductive parts in the housing which are directly or indirectly conductively connected to such wires. [0003] For metal parts that are enameled or otherwise coated so that they are electrically insulated, such press contacts are not sufficient to reliably establish an electrical connection. [0004] In order to establis...
