Electric soldering iron socket with temperature adjusting function

Abstract

The invention discloses an electric soldering iron socket with a temperature adjusting function. Box body, a power line is mounted on one side of the box body; a power supply indicating lamp and a digital voltmeter are mounted at the upper end of the front surface of the box body; a power switch, an adjusting knob and an output socket are mounted at the lower end of the front surface of the box body; a time-base integrated circuit NE7555, a rectifier bridge VD1, a power supply module MD1 and a power field effect transistor (MOS transistor) Q1 are installed in the box body. According to the electric soldering iron socket with the temperature adjusting function, a time-base integrated circuit NE7555 is adopted to form a multivibrator, a power field-effect tube Q1 is triggered, and the outputduty ratio is changed by adjusting a potentiometer POT1, so that the welding temperature of an electric soldering iron is adjusted, and the requirements of a welding process are met.

Description

technical field [0001] The invention relates to the technical field of electric soldering irons, in particular to an electric soldering iron socket with a temperature adjustment function. Background technique [0002] Electric soldering iron is an essential tool for electronic production and electrical maintenance. Its main purpose is to weld components and wires. According to the mechanical structure, it can be divided into internal heating type electric soldering iron and external heating type electric soldering iron. According to the control method, it can be divided into ordinary electric soldering iron and temperature adjustment electric soldering iron. The disadvantage of ordinary electric soldering iron is that the temperature cannot be adjusted, and it is greatly affected by the fluctuation of external environment temperature and power supply voltage. Different temperature requirements are required when welding different parts, while the temperature of ordinary elect...
