THIN-WALLED COVER PLATE FOR AN ELECTRIC SWITCH NIKO BELGIUM
The present invention relates to a thin-walled housing for an electric or electronic device that is made of lightweight composite concrete and has a thickness of between 1,5 mm and 15 mm.
Contemporary interiors more and more require modern finishing of electric or electronic devices, for example, cover plates for electric or electronic installation material such as switches, sockets, USB connectors and the like. One of the popular materials therefore is concrete. However, when thin housings are required, there is a high likelihood that these housings crack, burst or even break when forces are applied to it, for example, when installing or using it. This is because cement concrete can only withstand a very limited amount of tension stress. Such tension stress is induced by pulling, bending or torsion.
Solutions have already been provided: The cover plate is made of cement concrete and comprises a thin metal plate completely covered by the concrete in order to make it stronger. Two different materials are used and the metal plate has to be embedded into the concrete material.
It is an object of embodiments of the present invention to provide a thin-walled housing for an electric or electronic device that has a concrete look and feel but that is also strong and flexible and does not break or burst when applying forces to it.
