THIN-FILM ELECTRIC HEATER Russian patent published in 2018 - IPC H05B3/36 

FIELD: electricity.

SUBSTANCE: thin-film electric heater contains resistive element between two heat insulating films made of polymer film with conductive coating in the form of nano-sized layer across the entire width of which, on two edges, opposite each other, contacts are placed, made of material adhesive to current-conducting coating with current leads and terminals for connection to the electric mains. Current leads for connection to the electric mains are made of a material with low electrical resistance in the form of solid strip of foil over the entire length of contacts and are pressed against the contacts, furthermore, contacts are made in the form of planar figure, limited from two sides by periodic ondulations.

EFFECT: increased reliability by optimizing the contact shape by maximizing usage of the entire length of contact edge.
