Thermal monitoring device for charging system

A charging system comprising:

• a mobile charging device including a receiver power connector having a receiver housing extending between a front and a rear, the receiver power connector having a mating end at the front, the receiver housing having a receiver flange configured to be mounted to a body of a mobile device, the receiver housing having a receiver base extending rearward from the receiver flange through a body cutout in the body of the mobile device, the receiver housing including receiver power contact channels extending through the receiver base, the receiver housing including a funnel having an opening, the funnel having angled guide walls between the opening and a receptacle at the receiver base, the receiver power connector including receiver power contacts received in the receiver power contact channels, the receiver power contacts extending into the receptacle;
• a supply charging device including a supply power connector having a supply housing extending between a front and a rear, the supply power connector having a mating end at the front, the supply housing having a supply flange configured to be mounted to a panel of a charging component, the supply housing having a supply base extending rearward from the supply flange through a panel cutout in the panel, the supply housing including supply power contact channels extending through the supply base, the supply housing including a guide member extending forward from the flange, the guide member being received in the funnel of the receiver housing through the opening to locate the supply charging device relative to the mobile charging device, the supply power connector including supply power contacts received in the supply power contact channels, the mating end of the supply power connector being received in the receptacle such that the supply power contacts are mated to the receiver power contacts;
• and
• a thermal monitoring device coupled to either the receiver base of the receiver housing or the supply base of the supply housing, the thermal monitoring device including a substrate, a mating connector mounted to the substrate, and a temperature sensor mounted to the substrate, the temperature sensor being electrically connected to the mating connector, the temperature sensor being positioned in close proximity with the corresponding receiver power contact or the supply power contact for monitoring the temperature of the receiver power contact or the supply power contact.

An autonomous mobile device comprising:

• a mobile body movable relative to a supply charging device to perform a task and return to the supply charging device to recharge the autonomous mobile device;
• and
• a mobile charging device mounted to the mobile body, the mobile charging device being mated to the supply charging device to recharge the autonomous mobile device, the mobile charging device including a receiver power connector having a receiver housing extending between a front and a rear, the receiver power connector having a mating end at the front, the receiver housing having a receiver flange mounted to the mobile body, the receiver housing having a receiver base extending rearward from the receiver flange through a body cutout in the mobile body, the receiver housing including receiver power contact channels extending through the receiver base, the receiver housing including a funnel having an opening, the funnel having angled guide walls between the opening and a receptacle at the receiver base, the receiver power connector including receiver power contacts received in the receiver power contact channels, the receiver power contacts extending into the receptacle;
• the mobile charging device including a thermal monitoring device coupled to the receiver base of the receiver housing, the thermal monitoring device including a substrate, a mating connector mounted to the substrate, and a temperature sensor mounted to the substrate, the temperature sensor being electrically connected to the mating connector, the temperature sensor being positioned in close proximity with at least one of the receiver power contacts such that the temperature sensor is in thermal communication with the receiver power contact for monitoring the temperature of the receiver power contact.
