CURRENT-CARRYING LEAD AND PLUG CONNECTOR HAVING SUCH A CURRENT-CARRYING LEAD Russian patent published in 2016 - IPC H01R13/52 

FIELD: machine building.

SUBSTANCE: invention relates to a current-carrying lead, in particular a connecting lead and heating tape (5), for a plug connector. Current-carrying lead has at least two strands (49, 50) that are partly surrounded by electrical insulation (47). Current-carrying lead is provided with at least one reservoir (53) for electrically insulating medium (54). Reservoir (53) is closed by least one plunger (55), by means of which sealing medium (53) can be forced through at least one outlet nozzle (57) into at least one sealing chamber (58 to 60). Plug connector having current-carrying lead (3, 5) has sealing device (36) having sealing body (66). Sealing body has elastically deformable sealing part (71) that can be elastically deformed by means of wedge-type slider (77). Wedge-type slider (77) has conical face (82) that interacts with conical face (76) of sealing part (71). Wedge-type slider (77), which is preloaded axially by compression spring element (84), is guided in holding part (78) axially securing sealing body (66). Lead (3, 5) is supported in strain relief device (44) by a multi-point support, said strain relief device has four pressure pieces (91 to 94) respectively located opposite one another in pairs, of which one pressure piece pair (91, 92) is located at a right angle to other pressure piece pair (93, 94). One pressure piece pair (93, 94) are forcibly guided by the pressure pieces of other pressure piece pair (91, 92).

EFFECT: technical result is prevention of leakage currents that occur due to liquid in a plug connector, while maintaining the simple design and assembly of the connector.
