Self-control dual-adjustment soldering iron with long service life

Abstract

The invention discloses a self-control dual-adjustment soldering iron with long service life. An arrangement plane for stably arranging the soldering iron on a table consists of a supporting seat arranged on the lower part at the front end of the center of gravity of the soldering iron and a micro switch contact point arranged at the rear end of the center of gravity of the soldering iron. By the self-control under-pushing function between a contact point of a switch lever arm and the table and the slight contact of an accessory structure on the lever arm and fingers, duration of power level in each welding period and interval period of the soldering iron is dually adjusted, so that a good auxiliary welding effect is achieved, and optimal welding temperature is obtained during welding; and a soldering tip and a soldering iron core are appropriately cooled in the interval period, so that the soldering iron has high welding performance and ultralong service life; and besides, a double-color light emitting diode (LED) tube for monitoring power level, a power switch and a potentiometer for adjusting high power (20 to 80W or more) are additionally and integrally arranged on a handle of the novel soldering iron. By the soldering iron, the quality of the conventional universal soldering iron and an electric soldering iron of a welding station are comprehensively improved.

Description

(1) Technical field [0001] The invention belongs to an electric soldering iron used for welding, which is an indispensable tool in the production, manufacture and repair of electrical appliances and circuits. (2) Background technology [0002] As we all know, when using electric soldering iron, it is soldered and disconnected from time to time. During the gap period, the soldering iron is unloaded, and the temperature of the soldering iron tip reaches 350°-510°C (20-60W); and during each soldering period, the components need to be dipped in flux first to prevent it. The temperature of the soldering iron tip is only about 250°C for rapid volatilization; not only that, but the soldering, soldering temperature and holding time are quite different for different components. Therefore, for domestic and foreign soldering irons that only use one 220V power supply and have fixed power during different periods of welding and gap periods, there are always the following disadvantages: ...

AI Technical Summary

Problems solved by technology

[0005] Now popular domestic and foreign high-priced soldering stations (external electric soldering iron), although equipped with switches, sockets, intelligent high-frequency power voltage regulation, etc., are not automatically controlled, and it is difficult to operate the soldering station at the same time as the electric soldering iron, which is inconvenient to use. It is impossible to adjust the temperature: in each welding and gap cycle, timely adjust the temperature

Therefore, the disadvantages of the above-mentioned popular electric soldering irons still exist, and the price of the soldering station is high, which is several times or tens of times higher than that of the popular electric soldering iron, and the sales scope is limited.
