PROBLEM TO BE SOLVED: To provide a cable having a plug, a control circuit, and a substrate which can quickly and surely perform detection of an abnormal temperature without necessitating troublesome work such as an exchange of a fuse.SOLUTION: A cable having a plug includes: a plug that is connected to a receptacle connected with a secondary cell; a cable with one end connected to a terminal of the plug and the other end connected to power source supply means, that includes a power source supply line and a ground line; a switch that is installed on a substrate inside a housing of the plug and is inserted in series between a first terminal of the plug connected with the power source supply line and the power source supply means side of the power source supply line; a temperature sensor that is installed on the substrate and is installed adjacent to the first terminal of the plug connected with the power source supply line or to a second terminal of the plug connected with the ground line; and a control circuit that is installed on the substrate and blocks the power source supply line by turning off the switch if the temperature detected by the temperature sensor exceeds a predetermined value.SELECTED DRAWING: Figure 5 |
