FIELD CABLE Russian patent published in 2009 - IPC H01B11/00 

FIELD: electricity.

SUBSTANCE: invention is related to cable engineering, in particular to electric communication cables of multiple use. Cable has current-conducting strands, insulation-protection shell and weight-bearing element installed under specified shell. On each side of cable construction length there are connecting half-couplings, in body of each there is a contact block, to which the following components are welded - current-conducting strands of cable, sealing elements, and also unit for fixation of cable weight-bearing element. Unit of fixation is made in the form of pressing element consisting of two composite parts, every of which is made in the form of truncated cone split along axis and either thrust cone surface installed in middle part of cone internal surface, or press bushing with internal conical surface installed in middle part of body. Press element is located behind contact block, interacts with its conical surfaces to conical surface of body or press bushing and has ribbed internal surface that interacts with surface of cable insulation-protection shell.

EFFECT: higher rupture strength of cable in point of its sealing-off into half-coupling without violation of this cable insulation-protection covers integrity.
