Abstract

The utility model relates to a electric iron, in particular to a quick heating electric iron, which is characterized in that: the utility model comprises a primary coil (6), a junior loop (4) and an iron head (5). The junior end of a transformer is a cooper strip with a section of 3 to 7mm<2>, the circle is from 3 to 20, the junior loop (4) after shortcut is connected with the iron (5); the primary cooper strip is added with an insulation sleeve. When welding the components with a weld plate of large are or the components with a weld plate of a small area, an iron can ensure the speed is not effected, and won't damage to the instruments and the weld plate, the situation of void welding instruments happens rarely.

Description

A kind of electric iron that is rapidly heated

Technical field

The utility model relates to a kind of electric iron, particularly a kind of electric iron that is rapidly heated.

Background technology

Existing electric iron needs 1 fen more than the kind from connecting power supply to using, and generally using all is to continue to the electric iron energising after inserting power supply, up to the just powered-down of finishing using.Since in the operating process not very, scald people or detriment even cause that the thing of fire happens occasionally.In addition, because that existing electric iron temperature rises is slow, when the big element of solder pad area; need powerful electric iron ability hoisting velocity; and low power electric iron needs for a long time, through regular meeting device or pad is caused damage, or the situation of rosin joint device occurs.

Summary of the invention

The purpose of this utility model provides a kind of electric iron that is rapidly heated, it can weld with an electric iron together for solder pad area big element or the little element of bonding pad area, and can guarantee that programming rate is unaffected, be not easy device or pad are caused damage, the situation of rosin joint device seldom occurs.

The purpose of this utility model is achieved in that a kind of electric iron that is rapidly heated, and it is characterized in that: it comprises primary coil 6, secondary loop 4 and the solder horn 5 of transformer, and the secondary end of transformer is that sectional area is 3mm ²-7mm ²Copper bar, its number of turn is electrically connected with solder horn 5 after 4 short circuits of secondary loop between the 3-20 circle; Be with insulation sleeve on the secondary copper bar.

Primary coil 6 numbers of turn of described transformer are between 1300 circles-1500 circle.

The primary coil 6 loop electricity of described transformer are serially connected with switch.

Principle of the present utility model and advantage are: because the utility model is to be made of transformer and solder horn, the inferior of transformer extremely is that sectional area is 3-7mm ²Copper bar, its number of turn between the 3-20 circle, so its voltage is low, power is little, very safe.And directly by being connected with solder horn after the short circuit of secondary loop, heat conduction is fast, and energising back 2-5s generally speaking just can rapid welding component, as in circuit, adding switch, can be at any time with switching at any time and disconnecting, and safe and reliable.Can not cause damage to device or pad.

Description of drawings

Below in conjunction with the embodiment accompanying drawing the utility model is described further.

Fig. 1 is an embodiment accompanying drawing principle schematic;

Fig. 2 is a kind of embodiment external form figure.

Among the figure: 1, plug; 2, switch; 3, iron core; 4, secondary loop; 5, solder horn; 6, primary coil; 7, housing; 8, indicator lamp.

The specific embodiment

As shown in Figure 1, it has provided the principle key diagram, the number of secondary turns of transformer seldom, its number of turn is between the 3-20 circle, but line footpath is very thick, sectional area is at 3mm ²Or 7mm ²Or at 3-7mm ²Between, no matter the transcalent metal of material on iron core 3, is that sheet copper sheet or its skin of copper bar will be with insulation sleeve, in case short circuit as sheet copper sheet or copper bar.Primary coil 6 numbers of turn of transformer are at 1300 circles or 1500 circles or between 1300 circles-1500 circle.The thickness of concrete line designs according to industry power requirement.Be electrically connected with solder horn 5 after 4 short circuits of secondary loop.The primary coil 6 loops serial connection switch 2 of transformer.

Fig. 2 is that the circuit with Fig. 1 is fixed in the housing 7, and housing 7 one end areas are big, and an end area is little, it is evident that the end sealing transformer that area is big, on the thin end housing body of end that area is little or external diameter indicator lamp 8 and switch 2 is arranged.

Insert 1 back 2-3 second of attaching plug like this, welding component rapidly just, as in circuit, adding switch, can be at any time with switching at any time and disconnecting, safe and reliable.Can not cause damage to device or pad.

Claims (3)
