ABSTRACT:
A device is disclosed for closing and sealing of cable cutout bushings of major diameters, generally of a rectangular shape, as they are usually provided for leading through electrical cables with premounted plugs that can be used at interfaces of control enclosures or prefabricated walls and bracket systems in coupling or connecting elements as well as for switching cabinets and enclosures for the closing and sealing of major cable bushings. The device is molded mainly out of elastic material in which three functional elements are connected together to form one piece which combines three functional elements together, namely, (a) a sealing flange, (b) a conduit as connection part and (c) a cable sealing element. There is a middle part which in its inside forms a conduit of rectangular cross section with an inner diameter suitable to let serial plugs and a relevant number of cables pass through and an expandable cable sealing element is connected in one piece with a sealing flange which by a simple receptacle, an enclosure, or the connecting element of the bracket is pressed to the surface surrounding the cutout.
