SMART ALARM PLUG, SOCKET, WALL-MOUNTED SOCKET OR CONNECTOR

摘要

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.

1. A smart alarm plug, socket, wall-mounted socket or connector, comprising:
a casing, the casing being provided with a live wire pin, a neutral wire pin, a live wire connecting core wire and a neutral wire connecting core wire, the live wire pin being connected with the live wire connecting core wire, the neutral wire pin being connected with the neutral wire connecting core wire; a normally-open temperature control switch which is reset automatically, the normally-open temperature control switch being disposed in the casing, the normally-open temperature control switch being connected between the live wire pin and the neutral wire pin; a normally-closed temperature control switch which is reset manually, the normally-closed temperature control switch being disposed in the casing, the normally-closed temperature control switch being connected in series between the live wire pin and the live wire connecting core wire or between the neutral wire pin and the neutral wire connecting core wire, the normally-closed temperature control switch having a heat resistance value greater than that of the normally-open temperature control switch; and an alarm device used to send an alarm signal, the alarm device being disposed on the casing and connected in series with the normally-open temperature control switch.
