House connection for e.g. cables, has center plate with outer diameter that is smaller than inner diameter of tapping drill hole, and gasket pressed together between center plate and pressure plate

摘要

The connection has a center plate (13) at an inner side of a flange plate (6). The center plate has an outer diameter that is smaller than an inner diameter of a tapping drill hole (2). A gasket (14) made of elastic material rests against the center plate. A pressure plate (15) made of hard material e.g. steel is arranged at the gasket, where the center plate, gasket and pressure plate have through-holes for guide tubes (4, 5) and a lead screw. The gasket is pressed together between the center and pressure plates, while the flange and pressure plates are stayed together by screws.
