Abstract

The invention relates to a system for coupling of a lightwave conductor cable with many lightwave conductors (8) on coupling elements in a housing, which contains a clamping element for the end of the lightwave conductor cable and a number of coupling elements (9), which correspond with the number of the lightwave conductors to be plugged. According to the invention the end of the lightwave conductor cable is fixable by the clamping element on a chassis part or clamping flange (2) of the housing, and the lightwave conductors, which extend out from the cable end, are surrounded with a flexible cable sleeve. The ends of the cable sleeves, which are faced toward the cable end, are connected together and anchored in the clamping element. (FIG. 1)

Claims

1. System for coupling of a lightwave conductor cable (3) with many lightwave conductors (8) on coupling elements (9) in a housing, containing a clamping element (4-7) for the end of the lightwave conductor cable (3) and a number of coupling elements (9), which correspond to the number of the lightwave conductors, to be plugged such that the end of the lightwave conductor cable is fixable by the clamping element (4-7) on a chassis part or a clamping flange (2) of the housing, characterized in that the lightwave conductors (8), which extend out from the cable ends, are surrounded with a flexible cable sleeve (13), and the ends of the cable sleeves, which are faced toward the cable end, are connected together and are anchorable in the clamping element.

2. The system according to claim 1, characterized in that the housing has a front plate (10) with many coupling elements (9) for coupling onto the lightwave conductors (8) of the lightwave conductor cable and a chassis part with a bore for receiving the clamping element and a cover.

3. The system according to claim 1, characterized in that the clamping element (4-7) is formed as a screw element consisting of several parts, which is received in the bore of the back side of the housing, wherein the screw element contains a tension relief element, capable of being secured to the lightwave conductor cable end, and a splitting device (11), inserted in a receiving space of the screw element, and that the screw element is capable of being screwed on the chassis part or the clamping flange of the housing, and that the rear ends of the cable sleeves (13) are fixed in the splitting device (11).

4. The system according to claim 3, characterized in that the cable sleeves (13) are glued in the splitting device (11).

5. The system according to any of claims 1-4, characterized in that the clamping element (4-7) and/or the splitting device (11) are formed of synthetic material, particularly polyethylene.
