Description

Anti-overheated electric iron

Technical field:

The utility model relates to a kind of electric heating iron, particularly a kind of anti-overheated electric iron.

Background technology:

At present; Market is increasing to the demand of electronics, electric product; The connection of electronic component mainly connects through instruments such as electric iron, scolding tin, yet is heating wire by the inner core heating element heater of the electric iron that generally uses at present, and the heating-up temperature of heating wire is difficult to control; Be easy in use occur that electric iron head oxide layer comes off, time consumption and energy consumption, service life be shorter, influenced the quality and the outward appearance of solder joint greatly.

The utility model content:

The purpose of the utility model is in order to overcome above deficiency, a kind of anti-overheated electric iron is provided, thereby the constant temperature solder joint of realization electric iron to have improved solder technology.

The purpose of the utility model realizes through following technical scheme: a kind of anti-overheated electric iron, comprise solder horn, and be connected with sleeve pipe at the tail end of solder horn; Be provided with the flatiron handle in the sleeve pipe periphery, the part front end of sleeve pipe places outside the flatiron handle, is provided with thermistor heating elements at inside pipe casing; And the upper surface of thermistor heating elements and lower surface are fixed with electrode slice respectively, are connected with lead at the tail end of two electrode slices, and lead passes the flatiron handle and is connected with external power source; Since the special change resistance characteristic of thermistor heating elements, thus keep flatiron head constant temperature, and long-time welding can not produce oxide layer; Guaranteed welding quality, prolonged service life, and solder joint is big more; The quantity of heat given up of solder horn is high more, uses the range of application of flatiron to strengthen, and can be applicable to the welding of different big or small solder joints.

The utility model compared with prior art has the following advantages:

Its compact conformation, ingenious can make within temperature controlled certain scope, has improved the quality of solder joint, and has prolonged the service life of solder horn, energy-conserving and environment-protective more.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Label among the figure: 1-solder horn, 2-sleeve pipe, 3-flatiron handle, 4-thermistor heating elements, 5-electrode slice, 6-lead.

The specific embodiment:

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show a kind of embodiment of the utility model full automatic packing machine like Fig. 1, a kind of anti-overheated electric iron comprises solder horn 1; Tail end at solder horn 1 is connected with sleeve pipe 2, is provided with flatiron handle 3 in sleeve pipe 2 peripheries, and the part front end of sleeve pipe 2 places outside the flatiron handle 3; Be provided with thermistor heating elements 4 in sleeve pipe 2 inside, and the upper surface of thermistor heating elements 4 and lower surface be fixed with electrode slice 5 respectively, be connected with lead 6 at the tail end of two electrode slices 5; Lead 6 passes flatiron handle 2 and is connected with external power source, because the special change resistance characteristic of thermistor heating elements 4 can be controlled electric current and power consumption; Thereby keep 1 constant temperature of solder horn, long-time welding can not produce oxide layer, has guaranteed welding quality; Prolonged service life, and solder joint is big more, the heating power of solder horn 1 is high more; Quantity of heat given up is high more, uses the range of application of flatiron to strengthen, and can be applicable to the welding of different big or small solder joints.
