ABSTRACT:
A plurality of terminals already disposed in a housing of an electrical connector, include solder tails extending rearwardly from the housing which have a thin layer of magnetic material deposited on an outer surface thereof, so that respective wire ends may be placed therealong with solder preforms within lengths of heat recoverable tubing may be placed therearound and a high frequency current induced in the magnetic layer which then generates thermal energy sufficient to melt the solder and shrink the tubing forming terminations between the wires and the terminals and simultaneously sealing the terminations. The magnetic material may be nickel-iron alloy clad to a brass solder tail layer. The thermal energy is generated in an amount necessary to raise the temperature of the magnetic layer to its Curie temperature for the given frequency used and maintain that temperature. Each terminal thus includes an integral self-regulating thermal energy source, and the thermal energy radiates outwardly from the solder tails and is thus localized at the termination sites. The heating necessary to melt the solder is thus controlled in temperature and in location, substantially unaffecting the remainder of the connector, in an energy efficient process.
