Abstract
The new-type conduit fitting has at least a first, a second and a third part, through each part passes a hole which allows the parts to be pushed axially over the cable. The first part can be connected to a housing in an electrically conductive manner and can be axially tensioned with the third part. The second part is electrically conductive, and it reduces the cross section of its hole with increasing axial tensioning between the first and third parts. The hole of the first part expands conically against the second part, wherein the second part is a annular sleeve with a sheathing surface conically tapering against the first part and with a cylindrical inner surface, and the development of the annular sleeve has a shape meandering in a zigzag pattern. A fourth part formed as a rubber sleeve is positioned around the cable, and a fifth part formed as a union nut compresses the rubber sleeve between the union nut and the third part.
