Abstract
The utility model relates to an electric soldering iron. The utility model adopts that a circuit for connecting resistance wires is connected to a diode and a switch to realize the power variation of the electric soldering iron. Thus, the electric soldering iron in continuous work can retain operating temperature, and can not influence weld quality and the operation life of the electric soldering iron because of high temperature; the utility model has the advantages that saves power and prolongs the operation life.
Description
The utility model relates to a kind of electric iron.
Electric iron is the most frequently used a kind of instrument in the industries such as electronics, in order to engage various elements.The power of the electric iron that uses all is changeless at present, when electric iron conduction time is long, will cause solder horn overheated like this, cause welding quality to descend, the solder horn accelerated oxidation, resistance wire also blows easily, has to take to pull up frequently the practice that switch cuts off the electricity supply sometimes and reduces the temperature of electric iron, but cause the electric iron temperature wayward again, use inconvenience, disadvantages such as inefficiency.
The utility model purpose is to provide a kind of electric iron of energy appropriateness control temperature, when temperature is too high, its power is reduced, and has not only controlled temperature rise but also saved electric power, has improved welding quality and the service life that has prolonged electric iron.
Circuit structure diagram of the present utility model is equipped with a switch (1) and a diode (2) as shown in Figure 1 in the circuit of the resistance wire (3) that connects electric iron, switch and diode are to be connected in parallel.When normal use electric iron is worked, close a switch, electric current is by switch, and electric iron is with rated power work, time spent not too high or short time when the electric iron temperature, switch can be disconnected, electric current is realized the halfwave rectifier power supply by diode like this, current average reduces half, it is original 1/4 that the power of electric iron is also reduced to, and plays insulation effect, makes the temperature of electric iron both can remain on the operating temperature and be unlikely too high.Switch preferably is contained on the handle of electric iron, so that control at any time in operation.
4 is the shell of electric iron among Fig. 1, and 5 for connecting the ground wire of shell.
Fig. 2 is the cutaway view of electric iron, and 6 is solder horn, and 7 is bakelite, and 8 is handle.
Embodiment:
An electric iron according to technical characterictic making described in the utility model, rated power is 40 watts, and power supply is 220 volts, and the switch of packing in the circuit that connects resistance wire is the pushing switch of 250 volts of 1 peaces, the diode of packing into is 1N4005, and the pushing switch is contained in the front portion of handle.
Claims (2)
1, a kind of electric iron that is made of solder horn, housing, resistance wire and handle is characterized by on the circuit that connects resistance wire a diode and a switch is housed, and diode and switch are to be connected in parallel.
2, electric iron as claimed in claim 1 is characterized by on the handle that said switch is contained in electric iron.
