Description

The electric iron highly effective and safe energy saver of lengthening the life

The utility model relates to a kind of corollary apparatus of electric iron, especially a kind ofly can make the electric iron highly effective and safe energy saver of lengthening the life.

Existing electric iron does not generally have the function of protection self; when welding electrical equipment, electronic component with electric iron; be discontinuous weld interval; compare with the intermittent time weld interval; weld interval is very short, and electric iron causes the undue oxidation of solder horn because of bearing too high voltages for a long time; burn out heating, also cause waste of electric energy.Be difficult for weldbonding tin after the solder horn oxidation simultaneously and need remove oxide, waste the working time so again, quickened the loss of solder horn again.

In order to overcome above-mentioned shortcoming, the control device that existing electricity irons mostly is the transformer pressure-adjusting type, and its volume is big and heavy, function is few, is again manual stepping pressure regulation; Adopt the electric iron control device of thyristor voltage regulation circuit,, do not take on a new look to the protective effect of electric iron is basic, and generally do not have energy-conservation function, also be easy to generate noise jamming and damage though reduced volume and weight than transformer type.

The purpose of this utility model is exactly the shortcoming and defect that has overcome above-mentioned electric iron control device, improves the operating efficiency of electric iron welding, and more convenient safety and reliability prolongs the service life of electric iron and reaches the purpose of saves energy.

Control circuit box (1), insulation jar (2), weldment clip (3), base (4), leg (5), support (6), wire stripping cutter (7), solder box (8), electric iron (9) composition of being configured with of the present utility model.

Control circuit box (1) is made up of box body and built-in circuit board.The composition of control circuit as shown in Figure 2, among Fig. 2, XP ₁, FU ₁Be contained in the left side of box body, SA ₁, LED ₁Be contained in the right side of box body, SA ₂, SA ₃Be contained on the insulation jar, other elements all are contained on the circuit board, and the electric connection mode of each element is pressed Fig. 2 and connected.

The operation principle and the course of action of control circuit are as follows: 1, close SA ₁Switch, when supply voltage normal condition (for example more than 200 volts), the moment of taking out electric iron, insulation jar is rotated because of losing gravity balance, at this moment, mercoid switch SA ₃Closure, electric iron is directly powered by AC power; Stop several seconds and just can weld, after the Welder finished, the moment that electric iron inserts the insulation jar, the insulation jar rotated again and sets back, at this moment mercoid switch SA ₃Open, electric iron is powered by the AC power half-wave.So save electric energy, two come the electric soldering bit temperature to hang down can oxidation.Reached not only energy-conservation but also reached self-protection.2, when supply voltage is lower than 200 volts, three polar arm VT ₁End VT ₂Conducting, relay K ₁Action, contact K1-1 and K1-2 move simultaneously, connect 2 position.At this moment electric iron is by direct current supply, when needing welding, and mercoid switch SA ₂Closure, electric iron be by the DC power supply of full-wave rectification, when not needing to weld, and mercoid switch SA ₂Open, electric iron is by the DC power supply of halfwave rectifier.Control circuit has reached the automatic switchover to the automatic selection of electric iron power supply kind, preheating power supply state and welding power supply state.

Insulation jar (2) is to adopt pottery or glass or other resistant to elevated temperatures insulating materials to make a jar shape inner bag, forms with asbestos or other insulation materials parcel in its outside.The fixed outside of insulation jar two mercoid switches.The effect of insulation jar is; The support electric iron; Be the electric iron insulation; Drive mercoid switch automatic switchover power supply state.

Weldment clip (3) is to make with the metal material that can bear high temperature.Its effect is the soldered components and parts of clamping, lead, solder stick, prevents that the semiconductor element that is welded from burning out because of overheated.Welding job is convenient, increases work efficiency.

Support (6) is made with metal material, supports insulation jar fixedly weldment clip and two effects of slewing area of placing restrictions on the insulation jar.

Wire stripping cutter (7) is to make with stainless steel thin slice harder and that heat conductivility is good, and on working face, dig three circular arc cutaway that differ in size, lead is put into breach, use the electric iron heating wires, can peel off the enamelled coating of lead, plastic peel and enamel-covered wire.

Solder box (8) is to make with the high temperature resistant not metal material of sticking tin.Box body and lid two parts are arranged, in order to deposit scolding tin, rosin, solder paste.

The utility model is compared the beneficial effect that is had with background technology: 1, control circuit is simple, automaticity is high, without the operating voltage and the intermittant voltage of manual switch electric iron, and particularly also can operate as normal when supply voltage is very low; 2, energy-saving effect is obvious, but saves energy 50%; 3, electric iron is not fragile, but life-saving is more than 3 times; 4 work are convenient, safe and reliable, can increase work efficiency, and guarantee welding quality.
