Abstract
A tweezer-like heater structure includes a pair of arms that can be pivoted towards one another and a pair of legs having ferromagnetic temperature self regulating Curie point heaters at the ends of the legs, the legs being removably connectable to electrical connectors located in the arms whereby current is supplied to coils that energize the heaters. Heaters of different temperatures are provided by choosing heaters with ferromagnetic materials having different Curie temperatures. The structure is used as a soldering iron by inserting a heater with a proper shape in one arm and short circuitry the connector in the other arm.
Claims20
A tweezer heater structure comprising
- a main body,
- a pair of hollow arms having a generally elongated body and two ends,
- means for pivotally securing said arms in said main body for rotation of one end of each of said arms about a different pivot,
- means to cause the other ends of said arms to move toward and away from one another,
- at least one end of each end said arm being open ended,
- a heater for the ends of the arms,
- an electrical connector having at least two contacts located in at least one of said arms facing the open end of said arm,
- said electrical connector connected to the heater to supply electrical energy thereto.

- means to cause the other ends of said arms to move toward and away from one another,
- at least one end of each said arm being open ended,
- a pair of sleeves each disposed in a different one of said arms,
- different electrical connectors seated in each of said sleeves each facing the open end of its associated arms,
- a different Curie point heater each having an electrical adapter mateable with a different one of said electrical connectors,
- a different gear adjacent an end of each of said arms adjacent said means for pivotally securing said arms,
- said gears meshing with one another whereby pivotal movement of one arm towards the other arm provides pivotal movement of the other arm towards said one arm.
