ABSTRACT:
A high temperature thermocouple wiring harness and connector system incorporating multiple individual thermocouple probes replaceably attached through connectors to the wiring harness. Each connector has a wiring harness portion, a removable probe portion, and a fastener for holding the two portions together. The wiring harness portion has a housing and two electrical conductors connected to the cable of the wiring harness and having contact surfaces outside the housing. The removable probe portion has a similar housing, a thermocouple probe mounted on the housing, and two electrical conductors attached to the thermocouple and having contact surfaces outside the housing. The fastener retains the connector portions together and insures that the contact surfaces of the conductors are held together. The fastener is formed of a material that has a coefficient of thermal expansion less than the coefficient of thermal expansion of the connector portions. As the ambient temperature surrounding the connector increases, the lower relative coefficient of thermal expansion of the fastener in relation to the connector portion causes the conductors to be held together with increasing force.
