Abstract:
The invention relates to a tightening device for cable bushing arrangements comprising a rigid frame structure (1) having packing pieces (2,3) of which at least one (2) presents a cable-accommodating hole. The packing pieces (2,3) are arranged in rows to fill the frame structure (1) from one end. The tightening device includes a pressure plate (5) located between the frame structure (1) and the adjacent row of packing pieces (2,3), and a tightening element (6) between the frame structure (1) and the pressure plate to press the pressure plate (5) against the rows of packing pieces. According to the invention, this screw element (6) comprises a screw means connected to the pressure plate (5) and projecting therefrom for abutment with the frame structure (1). The free end of the screw is movable in relation to the pressure plate to produce a pressing action between the plate and the frame structure. The screw element (6) may comprise at least two parts (7,8,9) joined together by screwthreads and, when rotated relative to one another, changing the length of the screw element. One part (7) of the screw element (6) is attached to the pressure plate (5) and axially immovable in relation thereto.
