Device for cutting an optical waveguide fibre

摘要

Device for cutting an optical waveguide fibre (2) has a receptacle (1) which has a continuous bore (4) and relieves the tensile strain of the optical waveguide fibre, and has a clamping block (3) in which the optical waveguide fibre (2) which is guided through the bore (4) of the receptacle (1) can be clamped tight, the receptacle (1) having a cylinder (6) which can be rotated about the bore axis and on which a blade which is aligned with its cutting edge perpendicular to the bore axis is mounted so as to be radially displaceable, and the blade being radially outwardly displaced in a specific initial position of the rotatable cylinder (6) in order to clear the bore opening for the optical waveguide fibre (2) to pass through, and being pressed against the optical waveguide fibre (2) after the cylinder (6) is turned out of the initial position, and after the blade has scored virtually all around the optical waveguide fibre by turning the cylinder (6) the clamping block (3) which is mounted so as to be displaceable in the direction of the bore axis exerting a tensile force on the optical waveguide fibre (2) so that it tears off at the scored point (Figure 1). <IMAGE>
