Abstract
For a sealing insert of a cable gland it is proposed that the sealing insert be provided with a peripheral step which is adapted to a peripheral step in the pressure screw and that the sealing insert be provided on its outer diameter on the cable insertion side with a conical bevel which is adapted to the conical bevel of the pressure screw, the angle of the bevel of the pressure screw being designed to be more acute relative to the longitudinal axis.
Claims7
A cable inlet for electric and/or optical cables having at least one electric wire, wherein the wires of the cable are connected to contact elements in accordance with the axial connection method and wherein a pressure screw is provided which can be screwed to an accommodating housing and wherein a sealing insert is provided which can be actuated by the pressure screw, characterized in that the sealing insert (2) has a peripheral step (4) which is adapted to a peripheral step (3) in the pressure screw (1) and that a sealing insert outer diameter on an end facing the pressure screw has a conical bevel (9) which is adapted to a conical bevel (7) of the pressure screw (1), the angle of the conical bevel (7) of the pressure screw (1) being designed to be more acute relative to the longitudinal axis.
