SPIRAL UNIT FOR CABLE TENSION REDUCTION Russian patent published in 2015 - IPC H02G3/06 

FIELD: machine building.

SUBSTANCE: invention relates to a threaded joint (1, 100, 200, 300) of a cable for a plug connector casing, the casing body is equipped by a fitting (30, 120, 220) of a cable tap, and an element (40, 130, 230, 330) for tension reduction is provided, it has the first end and the second end which are interconnected by a spiral-like structure, the element ensures mechanical stabilization of the cable to be connected as soon as a terminal screw head (2, 110, 210, 310) is screwed in, the tension reduction element (40, 130, 230, 330) can be fixed against rotation at the first end (40a, 130a, 230a, 330a) inside the cable's threaded joint (1, 100, 200, 300), while the second end (40b, 130b, 230b, 330b) of the tension reduction element (40, 130, 230, 330) can rotate by means of rotation movement of the screw head (2, 110, 210, 310) in respect to the first end (40a, 130a, 230a, 330a).

EFFECT: invention provides for reliable reduction of cable tension and simple installation.
