ELECTROMAGNETIC POLARISED RELAY Russian patent published in 2016 - IPC H01H51/22 

FIELD: instrument making.

SUBSTANCE: invention relates to a high-voltage high-frequency electromagnetic polarised sealed relay for switching of no-load high-power radio circuits. Polarised electromagnetic relay comprises a base, an electromagnetic system consisting of two H-shaped cores form control windings and permanent magnet and armature in form of a lever consisting of two flat springs connected at one end with an insulating plate. Other end of flat springs is rigidly and cantilever mounted on base. On insulating plate on one side or each side there is at least one blade, opposite which is located a contact assembly and said permanent magnet is fixed to other end of insulating plate, cores of control windings arranged based on either side of permanent magnet with a gap relative to latter. Said base is made with a rack, which defines a groove, and said flat armature spring fixed to base by means of said rack with groove so that mountable to base end of each of leaf springs positioned in said recess and secured therein with rubber plates mounted between inner rack groove walls of each side and each end of said flat spring. Between the rubber plate and inner wall of groove on one or both sides of flat spring there is an adjustment strap. Part of volume of groove together with a portion of each of leaf springs located in said volume is filled with polymerisable material.

EFFECT: technical result is faster circuit relay.
