FIELD: electric engineering.
SUBSTANCE: plug joint comprises plug socket (3), plug (1) with electric cord (2), automatic system of plug joint disconnection, device for opening of contact seats, lever-disconnector (5) equipped with holder of electric cord (4), and plug pusher (6). Lever-disconnector is installed so that under action of electric cord tension force it interacts with device for opening of contact seats, which helps to contact pins to be easily extracted from contact seats under action of electric cord tension force. In case system for automatic disconnection of plug joint is available, lever-disconnector interacts with device for opening of contact seats via system of automatic disconnection of plug joint. In case plug pusher is available, device of contact seats opening may interact with plug pusher.
EFFECT: simplified disconnection of plug out of plug socket whenever electric cord is tightened with a force that is higher than the permissible one, which may occur due to spontaneous jerking of power supply cord.
