<p>A bushing for the sealing passage of a cable, pipe and the like through a wall, comprising a frame made of a rigid material which may be sealingly inserted in an aperture provided in the wall, as well as one or more parallelepipedal blocks of a resilient material such as rubber which may be composed from two identical halves, which blocks in their composite state exhibit a bore adapted with narrow tolerances to the shape and dimensions of a cable to be passed through, which blocks are inserted in the frame aperture so as to be a fine fit, with the two halves of every block encasing a cable, whilst in addition tightening means with a pressure body are present which compress the blocks inserted in the frame aperture in the plane of this aperture such that a sealing compression is effected between the two halves of any one block, between the outer faces of mutually adjacent blocks, between the wall of the bores and the outer surface of the cables contained therein, as well as between the outer faces of the blocks and the inner walls of the frame, whereby said tightening means are at least substantially integrated in said pressure body.</p> |
