Patent ID: 8878496

Claim:
A charger capable of charging an electronic apparatus, comprising: a charger main body including a power output unit, which outputs charging power, and a control unit, which controls the power output unit; a positive-side charging path for outputting, to the electronic apparatus, the charging power supplied from the power output unit; a negative-side charging path, which is electrically connected to a ground of the charger main body; a connection unit, which is attached to the charger main body and is capable of being connected to the electronic apparatus, the connection unit containing portions of the positive-side charging path and the negative-side charging path respectively extended from the charger main body; a temperature sensor, which is arranged in the vicinity of the portion of the positive-side charging path in the connection unit; and a first signal line, which communicates temperature information detected by the temperature sensor; wherein the connection unit includes a metallic outer wall, which surrounds outside of the portions of the positive-side charging path and the negative-side charging path, wherein at least the portion of the negative-side charging path is electrically connected to the metallic outer wall, and wherein the control unit is capable of receiving the temperature information from the temperature sensor through the first signal line regardless of presence or absence of the connection to the electronic apparatus, and stops the output of the charging power from the power output unit if temperature detected by the temperature sensor is higher than or equal to a prescribed temperature.
