FIELD: plug connectors for cables of subsurface workings of mines. ^ SUBSTANCE: proposed cable-terminating plug forms hollow plug socket of brass whose hollow section on cable end forms cable entry hole and has supporting collar that functions to support male connecting member projection in axial direction. Cable entry hole is provided with inner thread for turning in metal tetrahedron that has through hole for cable entry. Cable screen or armor can be placed between through hole and cable sheath to ensure adequate grounding of cable and cable plug. Inner space of plug socket is sealed by means of shaped part molded on cable sheath, on plug socket, and on polyhedron. Shaped part is also used for securing cable in axial direction on plug socket. ^ EFFECT: ability of long-time service in damp media due to reliable sealing attained by simple means. ^ 13 cl, 3 dwg |
