Abstract:
1. A feed-through device for a sealed feed-through of an elongated part, a tube, a hose or a cable, through an opening in a mounting wall, comprising: a hollow cylindrical tubular fitting that is connectable to the mounting wall and has a fitting channel for receiving the elongated part and a first outer thread; a cap nut with a feed-through opening for receiving the elongated part and with an inner cap thread that is connected to the first outer thread of the tubular fitting; a sealing member arranged within the cap nut and having a receiving channel for receiving the elongated part, wherein the tubular fitting has, adjacent the first outer thread, a cylindrical sealing wall and wherein the cap nut has, adjacent the inner cap thread, a closing flange that holds an elastic sealing ring, the ring resting and tightly sealing on the sealing wall and the ring being axially movable along the sealing wall when the cap nut is turned relative to the tubular fitting; a clamping collet seated within the tubular fitting, the clamping collet having a collet channel for feed-through of the elongated part, and a lamella crown arranged within the cap nut above the first outer thread of the tubular fitting and that embraces the sealing member; wherein the tubular fitting has within the fitting channel an inner mounting flange with at least one guiding groove aligned parallel to a longitudinal axis of the tubular fitting and wherein the clamping collet has a mounting cylinder with a guiding fin on an outer side, the guiding fin being axially movable within the guiding groove; wherein the clamping collet has a collet ring arranged adjacent to and radially extending beyond the mounting cylinder, the collet ring supporting on one side the lamella crown and having on another side a rind shoulder that is seated on the inner mounting flange; and wherein a transition region is provided between the first outer thread and the cylindrical sealing wall, the cylindrical sealing wall having a larger diameter than a diameter of the first outer thread of the tubular fitting.
