PUNCH-DRIVEN BOND Russian patent published in 2013 - IPC B60M5/00 E01B11/00 

FIELD: transport.

SUBSTANCE: invention relates to railway equipment, particularly, to appliances intended for increasing conductivity of rail joints at sections equipped with automatic block units. Punch-driven bond consists of multicore flexible copper or steel-copper conductor secured in lugs to be welded to rail head sides. Lug ends are skewed. Conductor is clipped in lugs. Lug is composed of steel tube. Part of said lug connected to rail head sides is flattened to make surface shifted relative to lug axis and shaped to trapezoid one of sides of which making lug end. Inner side of lug part intended for fastening the conductor is coated with antirust compound and hydrophobic lubricant. Conductor is clamped by two hexagonal rings to allow minimum transient resistance in conductor-lug assembly. Conductor lengthwise axis is shaped to omega pattern in the plane parallel to rail head side surface. Lug is welded to rail head side surface.

EFFECT: higher safety and reliability.
