Housing for an electric appliance
A housing for an electric appliance includes a wall with an electrically insulating solid structure, an electrically conductive skin that is fastened to the solid structure, an electrically conductive support, and at least one screw that engages into a bore of the structure and keeps the support pressed against the wall. The screw extends through a recess of the electrically conductive skin. Material of the electrically conductive skin that surrounds the recess is displaced by the screw.
1. A housing for an electric appliance, the housing comprising:
a.) a wall having an electrically insulating solid structure and an electrically conductive skin that is fastened to the electrically insulating solid structure, the electrically insulating solid structure of the wall having at least one hole and the electrically conductive skin of the wall having a recess;
b.) an electrically conductive support having a hole; and
c.) at least one screw, the screw extending through the hole of the electrically conductive support and engaging the hole of the electrically insulating solid structure of the wall to resist movement of the electrically conductive support away from the wall, the screw extending through the recess of the electrically conductive skin of the wall and displacing material of the electrically conductive skin of the wall that surrounds the recess.
2. The housing as claimed in claim 1 , wherein the recess of the electrically conductive skin of the wall is a hole.
3. The housing as claimed in claim 1 , wherein the recess of the electrically conductive skin of the wall includes a serrated edge that is deformed by the screw.
4. The housing as claimed in claim 1 , wherein the recess of the electrically conductive skin of the wall includes two serrated edge that are deformed by the screw and the two serrated edges of the recess lie opposite one another.
5. The housing as claimed in claim 1 , wherein the electrically conductive skin is a metal panel forming an outer cover of the housing.
6. The housing as claimed in claim 1 , wherein the electrically insulating solid structure of the wall is a molded part made of plastic.
7. The housing as claimed in claim 1 , wherein a metal panel forming the electrically conductive skin has a layer of enamel thereon with an absence of the layer of enamel in the vicinity of the recess.
8. The housing as claimed in claim 1 , wherein the housing is a refrigerator housing and the electrically conductive support is operable to support a compressor.
