Temperature-regulating energy-saving life-prolonging power supply socket of electric soldering iron

Abstract

The invention relates to a temperature-regulating energy-saving life-prolonging power supply socket of an electric soldering iron. The socket is characterized by comprising a 220V alternating-current power supply, a resistance-capacitance phase-shifting and triggering circuit, a double-direction thyristor control circuit and an electric soldering iron socket body CZ, wherein the resistance-capacitance phase-shifting and triggering circuit comprises a linear potentiometer RP, a resistor R1, a capacitor C1, a trigger diode D1 and a trigger diode D2, and the type of the trigger diode D1 and the trigger diode D2 is 1N 4004; the double-direction controllable silicon control circuit is connected with one end of the electric soldering iron socket body CZ through a second anode T2 of a double-direction thyristor BCR, the other end of the electric soldering iron socket body CZ is connected with the live wire end L of the 220V alternating-current power supply, and a first anode T1 of the double-direction thyristor BCR is connected with the zero line end N of the 220V alternating-current power supply. The socket has the advantages that the circuit is simple, power of the electric soldering iron can be used for stepless temperature adjustment according to actual requirements, manufacturing cost is low, the phenomena that temperature is too high and the electric soldering iron is burnt out are overcome, power conservation of the electric soldering iron is achieved, and the service life of the electric soldering iron is prolonged.

Description

technical field [0001] The invention belongs to the technical fields of electronic technology and temperature control, and relates to a temperature-adjusting, energy-saving, and life-prolonging power socket for an electric soldering iron. Background technique [0002] The variety of soldering irons on the market has remained largely unchanged over the years. During the repair of various electrical appliances and electronic equipment, it is usually necessary to use instruments to measure circuits, analyze faults, and organize components. During this period, the electric soldering iron must always be powered on for use at any time. Experience tells us that most of the time during the working period of the electric soldering iron is in a state of continuous energization and heating, and the time for actually using the electric soldering iron is very limited. It is caused by power on and the temperature of the electric soldering iron is too high; in addition, the temperature of...

AI Technical Summary

Problems solved by technology

[0004] The soldering iron core is made of nickel-chromium alloy wire. Since the power of the soldering iron is proportional to the square of its supply voltage, that is, if the supply voltage drops slightly, the power of the soldering iron will be greatly reduced.
