Abstract
An improved soldering-desoldering instrument is disclosed which includes a stainless steel, thin walled sheath having a front end which is both internally and externally threaded: internally for securing the electric heater cartridge, and externally for securing the soldering tip, all in very high thermal energy flow relation. The rear of the sheath is formed integrally with a hexagonal nut to facilitate the indicated threaded assembly and disassembly.
Claims3
In a soldering instrument:
- a substantially cylindrical, thin-walled stainless steel sheath having a reduced diameter front end formed with both internal and external threads which are coaxial with said sheath and having hexagonal nut formed integrally with its rear portion;
- a substantially cylindrical, highly heat conductive heater cartridge disposed coaxially within said sheath and an externally threaded front end threadingly engaged with said internal threads of said sheath;
- an internally threaded soldering tip disposed in threaded engagement over said external threads of said sheath whereby
- said front end of said heater cartridge and the threaded portion of said soldering tip are axially coincident and in high thermal energy flow relationship with each other;
- and
- a heater element of the character to be electrically energized disposed within said cartridge in direct thermal contact therewith.
