METHOD OF ELECTRICALLY PARALLEL BUSSED LINK OF ELECTRIC LAMP OF IRR TYPE FOR INFRARED HEATERS Russian patent published in 2018 - IPC H05B3/00 

FIELD: electricity.

SUBSTANCE: only one set of one bus pair is used, in which holes in phase bus are performed under sleeve with thread E40 and sleeves are fixed in them with internal thread E40, each of which is provided with screw through radial M5 screw hole in the bottom of the sleeve and butterfly screw with possibility of driving it into the sleeve screw hole, completing additional phase bus with cylindrical threaded sleeves with external thread E40 and internal thread E27 with opportunity of driving threaded sleeves inside the sleeve with thread E40 and fixing them with butterfly screw so that the lower ends of both sleeves, turned to the neutral bus, lie in one plane, and neutral bus is made of mechanically nontreated metal, wherein connection of buses with lamps is carried out so that the lamp IRR-500 are screwed into threaded sleeve E40 until it stops with an interference fit in the neutral bus and fixed with the butterfly screw, and lamps IRR-175 or IRR-250 are screwed into the threaded sleeve as far as it stops with an interference fit in the neutral bus and fixed, and threaded sleeve is driven in fixed sleeve with thread E40, while the phase and neutral buses are performed of the same thickness.

EFFECT: simplification of manufacture, increase of reliability, increase of connection reliability, reduction of material consumption.
