Abstract
Abstract A self-regulating heater for integrated circuits and the like is removably carried in a connector assembly. The connector assembly includes a housing which on one side is adapted to receive an integrated circuit unit or the like and which on the other side removably receives in a force fit a base plug which in turn is adapted to be plugged into a circuit board. The heater includes a heating element composed of material having a positive temperature coefficient of resistance. Contacts are provided on the heating element which are in resilient spring connection with heater terminals mounted in the base plug. By reaction the heating element is pressed against a heater plate also carried within the connector assembly. A rim of the heater plate is supported upon the margin of an opening or window in the housing so that an integrated circuit unit or the like mounted on the housing is placed in heat-exchange relationship with the heater plate whereby the temperature of the integrated circuit unit or the like is stabilized. Interchange may readily be made between various heater elements to provide desired changes in the regulated temperature.
