Kind Code:
A
Abstract:
To provide an outlet device that can detect heat generation due to poor contact of an inserted plug without being affected by the ambient temperature, and shut off an electric circuit when the heat generation due to poor contact occurs.SOLUTION: An outlet device is provided with a detection circuit 14 in which a contactor 12 with which the tip of a plug blade 2a contacts is arranged behind a blade receiving spring 11 that sandwiches the plug blade 2a of a plug 2, and detects a voltage difference between the contactor 12 and the blade receiving spring 11, and a determination circuit 15 determines that a contact failure has occurred when the voltage difference detected by the detection circuit 14 exceeds a predetermined value, and a cutoff circuit 16 that shuts off an alarm circuit that notifies the determination and the blade receiving spring 11 from a power supply 4 when the determination circuit 15 determines that the contact is poor.SELECTED DRAWING: Figure 2
