RAIL BUTT ELECTRICAL INSULATION CONNECTION Russian patent published in 2021 - IPC E01B11/54 B60M5/00 

FIELD: railways.

SUBSTANCE: invention relates to the field of the upper build of the railway track, in particular to the butt electrical insulating connections of rails. Composite insulating overlays with two composite locking plates are placed on both sides of the rails to be joined. The plates are made in the form of elongated elements with transverse through holes. The fasteners are placed in the holes and the composite overlays and locking plates are pulled together through the rail neck. One of the locking plates on each side of the rails contains a protrusion with a magnetic shunt insert. The protrusion overlaps with the adjacent flat locking plate.

EFFECT: magnetic field strength in the area of the insulating joint of the rails decreases.
