Patent number: 8902555Abstract: A smart alarm plug, socket, wall-mounted socket or connector includes a casing, a normally-open temperature control switch, a normally-closed temperature control switch and an alarm device. The casing is provided with a live wire pin, a neutral wire pin, an earth wire pin, and connecting core wires. The heat resistance value of the normally-closed temperature control switch is greater than the heat resistance value of the normally-open temperature control switch. When the temperature of the power wire is abnormal, the normally-open temperature control switch will be closed for the alarm device to connect with the power, such that the alarm device sends an alarm signal to warn the user to examine the circuit, providing a warning effect. When the temperature is over the preset value, the normally-closed temperature control switch will be opened to cut off power supply, achieving a fire alarm effect.Type: GrantFiled: April 9, 2013Date of Patent: December 2, 2014Inventor: Chi Wen Cheng
