Abstract
Provided is a cartridge soldering iron having a hollow cylindrical handle, incorporating an internal coaxial socket assembly, a connection to a power supply, and a cartridge housing support, and a soldering tip bearing cartridge incorporating a tip, a heater assembly, a tubular housing and a coaxial socket assembly adapted to mate with the handle socket assembly in a wiping electrically conductive manner.
Claims15
A heater structure comprising
- a cartridge having a low heat conductive tube, a heat generating means including a coil permanently fixed in one end of the tube, and
- a first electrical connector permanently fixed in the other end of the tube, and
- an elongated, hollow holder of non-heat conducting material having first and second ends,
- a second electrical connector located adjacent one end of said holder and adapted to couple with, mechanically support and removably retain said cartridge in said holder and apply electricity to said first connector,
- first means for laterally supporting said cartridge located adjacent the other end of said holder and substantially isolating said holder from the heat of said heat generating means.
2 more elements
A heater structure comprising
- a cartridge having a heat generating tip member located adjacent one end of said cartridge,
- a first connector located at the other end of said cartridge,
- a low heat conducting tube extending between and supporting both the heat generating means and said first connector,
- an elongated, hollow cartridge holder of low heat conducting material and having a first and second end,
- a second electrical connector located adjacent said first end of said holder and adapted to receive and removably support said first connector,
- said cartridge extending through said second end and an intermediate region of said holder with said first connector seated in said second connector,
- the cartridge and holder having dimensions such that air space exists therebetween except in the region of said connectors, and
- slip fit means for solely supporting said cartridge adjacent said second end of said holder.
5 more elements
A combination including
- a heater cartridge, and
- a handle for said heater cartridge,
- said heater cartridge comprising a low heat conducting tube, a heat generating means substantially permanently fixed in one end of the tube, and
- a first electrical connector substantially permanently fixed in the other end of the tube,
- said handle comprising an elongated, hollow holder of non-heat conducting material having first and second ends,
- a second electrical connector located adjacent one end of said holder and adapted to couple with, mechanically support and removably retain said cartridge in said holder and apply electricity to said first connector,
- first means for laterally supporting said cartridge located adjacent the other end of said holder and substantially isolating said holder from the heat of said heat generating means, and
- coil means of electrically conductive material located within a member of said combination so as to efficiently couple magnetic flux to said ferromagnetic material whereby to heat said ferromagnetic material to a temperature approaching its Curie temperature upon said coil being connected across a source of constant current.
5 more elements
An article of commerce comprising
- a heater cartridge comprising
- a hollow, straight, low heat conducting tube having open ends,
- one element of a slip fit coaxial electrical connector permanently secured in one end of said tube,
- a heater member located within and permanently secured in the other end of the tube,
- electrically conductive means extending between said connector and said heater member whereby upon said connector being coupled to a source of electrical energy said heater member produces heat.
