HEAT-RETAINING SOLDERING IRON Russian patent published in 2013 - IPC B23K3/02 

FIELD: process engineering.

SUBSTANCE: invention may be used for repair and wiring of electrical devices. Heat power accumulator is composed of copper cylindrical chamber 1 filled with lead 2 and arranged in thermal contact with heat conducting bushing 3 with bit 4. Soldering iron is furnished with annular electrode 6. Tubular heating element 5 with heat emitting conductor is arranged inside chamber 1 and electrically connected therewith. Chamber 1 contacts via heat conducting bushing with soldering bit 4 and annular electrode 6. Chamber 1 is fitted in heat-insulation jacket 7 with heat-reflection inner walls filled with ceramic dielectric filler 8 that makes the first heat insulation layer. Jacket 7 is fitted in soldering iron thin-wall handle 9. Space between jacket 7 and handle 9 is filled with porous heat-insulation material 10 that makes the second heat-insulation layer. For charging, soldering iron is placed at the support connected with controlled power supply. Soldering bit has heat and electric contacts with spring-loaded electrode of said support while annular electrode has electric contact with U-like electrode of said support.

EFFECT: better soldering performances, ease of handling.
