  • Electrical connector including variable resistance to reduce arcing
    Patent number: 6659783
    Abstract: Electrical connectors (40, 104) including contact terminals that can be unmated without previously disconnecting power include main contacts (12, 112) and auxiliary contacts (16, 130) that are shunted by a positive temperature coefficient (PTC) resistor (6, 140) located between the main and auxiliary contact. The main contact (12, 112) will be disconnected first and the auxiliary contact (16, 130) can be longer than the main contact (12, 112). Arcing will not occur at the mating end of the main contact (12, 112), because the current will be shunted to the still connected longer auxiliary contact (16, 130). I2R heating will increase the resistance in the PTC resistor (6, 140), so when the auxiliary contact (16, 130) is disconnected, current will be below the arcing threshold.
