Safe electric soldering iron for electronic practice

Abstract

The invention discloses a safe electric soldering iron for electronic practice. The safe electric soldering iron comprises a soldering bit and a handle, wherein the handle comprises a guide shell and a movable shell, a first elastic piece for pushing the movable shell is arranged in the guide shell, the soldering bit is arranged on the handle in a penetrating manner, one end of the soldering bit is fixed or movably limited in the movable shell, a guide hole is axially formed in the movable shell, a limiting part penetrating into the guide hole is arranged on the guide shell, a movable rod is arranged on the movable shell, a limiting hook is arranged on the movable rod, a second elastic piece and an electromagnet are arranged at one end of the movable rod, at least one end, close to the electromagnet, of the movable rod is made of iron, the other end of the movable rod extends out of the movable shell, and electric conductors are arranged on the peripheries of the guide shell and the movable shell. The outer surface of the soldering bit is made of conductive materials, a control circuit board is arranged in the handle, the electric conductors, the soldering bit and the electromagnet are all connected to the control circuit board, the electric soldering iron can effectively prevent the body from being burnt by the soldering bit, and safety is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electric soldering irons, in particular to a safe electric soldering iron for electronic practice. 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 heat type electric soldering iron and external heat type electric soldering iron. Tin-type soldering irons are divided into high-power soldering irons and low-power soldering irons according to different uses. [0003] The electric soldering iron is composed of a soldering iron tip, a soldering iron core, a shell, a handle, a power lead, a plug, etc. During use, the soldering iron core is energized to generate heat, and the temperature of the soldering iron tip is relatively high during use. When soldering, Generally, one hand holds the circuit board and compone...

AI Technical Summary

Problems solved by technology

[0003] The electric soldering iron is composed of a soldering iron tip, a soldering iron core, a shell, a handle, a power lead, a plug, etc. During use, the soldering iron core is energized to generate heat, and the temperature of the soldering iron tip is relatively high during use. When soldering, Generally, one hand holds the circuit board and components or solder bar, and the other hand operates the electric soldering iron for soldering. Careless contact can easily cause hand burns, and it is more dangerous for people without operating experience.
