Temperature sensor assembly for an electrical connector

A charging inlet assembly comprising:

• a housing extending between a front and a rear, the housing having a mounting flange for mounting the housing to a vehicle, the housing having a charging port configured to receive a charging connector, the housing including a chamber at the rear;
• an electrical connector within the charging port of the housing, the electrical connector including terminal channels open at the front to receive the charging connector, the electrical connector including power terminals received in the terminal channels, each power terminal includes a mating pin at a front of the power terminal and a cable connector at a rear of the power terminal, the mating pin positioned in the corresponding terminal channel for mating with the charging connector, the cable connector extending into the chamber for electrical connection to a power cable;
• and
• a temperature sensor assembly positioned in the chamber, the temperature sensor assembly including a sealing pad holding the power terminals, the temperature sensor assembly including a thermal shunt held by the sealing pad, the temperature sensor assembly including a temperature sensor coupled to the thermal shunt, the sealing pad having terminal openings receiving the power terminals, the sealing pad being electrically insulative to electrically isolate the power terminals, the sealing pad being thermally coupled to the power terminals and thermally coupled to the thermal shunt, the sealing pad having a first thermal conductivity, the thermal shunt having a second thermal conductivity higher than the first thermal conductivity, the sealing pad having a first thermal diffusivity, the thermal shunt having a second thermal diffusivity higher than the first thermal diffusivity, the sealing pad electrically isolating the thermal shunt from the power terminals, wherein the temperature sensor engages the thermal shunt to monitor the temperature of the power terminals through the sealing pad and the thermal shunt.
