Claims

[Scope of Claim for Utility Model Registration] (1) An electric soldering iron comprising a soldering iron body having a grip, a soldering iron tip provided on the front end, and a power cord connected to the rear end. , the soldering iron tip includes a soldering iron tip and a heater, the soldering iron tip has a divided structure consisting of a tip and a base, and the base has a cavity for inserting the heater. A heater part that heats the soldering tip and a sensor part that detects the temperature of the soldering iron tip are provided at the tip part of the heating heater, and the tip part of the heating heater is provided at the tip part of the soldering iron tip. An electric soldering iron characterized in that the base of the tip and the heater are integrally fixed in close contact with each other by being inserted into a cavity of the base and filled with an inorganic adhesive between the two. (2) The rear end surface of the tip of the soldering tip is a conical concave surface, and the tip surface of the base of the soldering tip is a conical convex surface corresponding to the rear end surface of the tip. An electric soldering iron according to claim 1 of the utility model registration claim. (3) The electric soldering iron according to claim 2, wherein conductive metal plating is applied to the rear end surface of the distal end and the distal end surface of the base of the soldering iron tip.
