Composite heating type heat storage soldering iron

Abstract

The invention discloses a composite heating type heat storage soldering iron which comprises a hollow soldering iron core, wherein a soldering iron head is arranged at one end of the soldering iron core, the other end of the soldering iron is connected with a handle, an inner heating wire is arranged inside the hollow soldering iron core, an inner heating electric wire is connected to a position,near the inner heating wire, of the inner heating wire, a hollow heat storage metal block is arranged on the exterior of the soldering iron core in a sleeving manner, an external heating wire is arranged on the exterior of the soldering iron core in a winding manner, and the external heating wire is positioned inside the hollow chamber of the heat storage metal block. The composite heating type heat storage soldering iron provided by the invention has a simple structure, has various heating ways, is fast in heating and affected little by the environment, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of soldering irons, in particular to a composite heating heat storage type soldering iron. Background technique [0002] Soldering iron is an essential tool for electronic production and electrical maintenance. It is mainly used for welding electronic components and wires. According to the mechanical structure, it can be divided into internal heating electric soldering iron and external heating electric soldering iron. [0003] The shape of the soldering iron tip used in the existing ordinary internal heating electric soldering iron is hollow cylindrical, the heating element is covered by the soldering iron tip, the preheating time is short, the general internal heating power is below 50W, and the common internal heating electric soldering iron is about 20W ~ 30W , so when the ambient temperature is low, it is greatly affected by the change of ambient temperature. Ordinary external heating resistance wire i...

AI Technical Summary

Problems solved by technology

It is less affected by the change of ambient temperature, but because of the electric heating wire nested outside the tip of the soldering iron in the AC power source used in the external heating type, induced voltage is easily generated on the tip of the soldering iron, and the induced voltage will have an impact on the soldered electronic components, seriously It will burn out electronic components, so when welding field effect tube components and chips, the soldering iron must be powered off or grounded before proceeding.
