Abstract
The invention relates to an abnormity alarm for a connector of an electric junction box, belonging to the technical field of application electronics. A circuit consists of a 555 integrated circuit, resistors, capacitors, a triode and a horn. The alarm is characterized in that the second pin of the 555 integrated circuit is connected with a fifth variable resistor; a first thermistor, a second thermistor, a third thermistor, a fourth thermistor and the fifth variable resistor are connected in series, and are connected with two ends of a direct current power supply. By adopting the technical scheme, the abnormity alarm has the advantages that an alarm is sent out when the temperature of the connector of the electric junction box rises due to poor contact, and potential hazard can be eliminated in time.
