Device for the mutual fastening of two housing shells

摘要

In the two housing shells (1, 2) there are provided, on the mutually facing edges in the region of the screw connection, in each case semicircular cutouts which together form a circular opening corresponding to the screw diameter. The screw nuts are designed in each case as plain nuts (4) and have in each case at least two protrusions (5, 6) which are directed towards the inner wall of the two housing shells (1, 2) and dip into depressions which are provided there and are arranged in a mirror-symmetrical manner with respect to the mutually facing edges of the housing shells (1, 2). <IMAGE>
