CONTROL SENSOR Russian patent published in 2024 - IPC H01H39/00 

FIELD: explosive electrical equipment.

SUBSTANCE: invention relates to explosive electrical engineering, namely to disposable devices and is intended for monitoring the state of systems based on explosives upon breakage of electrical circuits. Control sensor comprises a housing made in the form of a cup closed by a cover, with a flange at the base and a through hole in the side surface, a contact group located in the inner cavity of the housing at its base and comprising a piston with a projection, retainer and insulator, and electric control circuits extending beyond the housing through a through hole in its side surface. Sensor contains at least two electric control circuits. Through holes are made in the piston, in one of which the fixture is installed. Contact group is pressed by a nut to the base of the housing and contains a sleeve made in the form of a cup with through holes in the side surface, which is installed with its free end to the base of the housing. In the inner cavity of the sleeve there is a piston with a retainer passing through holes in the side surface of the sleeve, on the outer surface of which an insulator is installed. Piston protrusion rests against the free end of the sleeve. Electric control circuits pass through the holes of the piston and the sleeve at an angle relative to each other and are located along the outer side surface of the sleeve.

EFFECT: increased safety of the sensor, increased number of broken electric control circuits.
