FIELD: electricity.SUBSTANCE: blocked device for a fast connection key in electrical mechanisms consists of an additional device (2), situated at the bottom end of a fast connection key (1) and connected thereto by a region (4) which gives the connection flexibility and allows displacement of the entire device (2) closer to the key (1) by pressing on or separation therefrom and return thereof to the initial position by ceasing the application of pressure which may be applied to the device (2) or to a hook (3), by which the device (2) ends at its bottom end. During rotary displacement of the key (1) and approach to the outer surface (6a) of the housing (6), the end hook (3) of the device (2), which makes up the blocking device, comes into contact with the bottom outer surface (9a) of the bottom protrusion (9), centrally symmetrical to the housing (6), while sliding thereon until said hook is fixed at the top edge (9b) of the protrusion (9), wherein the entire key (1) is fixed in a connection position.EFFECT: preventing accidental displacement of the fast connection key, which leads to separation of the device from the housing and movement of the electrical mechanism into an off position.3 cl, 5 dwg |
