Abstract

The utility model relates to a quick-acting electronic iron. A power supply line of the quick-acting electronic iron is connected with an electronic transformer which is composed of a frequency conversion electronic circuit and a high frequency transformer in an insulated handle. The electronic transformer is connected with an iron head outside the insulated handle. A power frequency voltage is converted into a high frequency low voltage and a high current by the utility model. The high frequency low voltage and the high current are quickly converted into heat energy through the iron head. The utility model has the advantages of good heat transferring effect, quick welding, little power consumption and portable style. The quick-acting electronic iron is a tool for maintaining and welding electronic circuits.

Description

The swift electron flatiron

The utility model is a kind of electronics soldering iron device.

At present, the quick flatiron of traditional type resistance wire flatiron and transformer type is arranged on the market.The quick flatiron of transformer type is a principle of using electric welding machine, civil power is directly changed into low-voltage, big electric current by Industrial Frequency Transformer, and be solder horn by a short circuit metal silk that is connected in parallel on its secondary two ends, realize that electric heating changes fast, reach the purpose that molten soldering connects.Though its heating is fast, its transformer energy consumption is big, style heaviness, and short circuit metal silk solder horn heat-transfer effect is poor, and when long-time welding, the transformer damage of easily generating heat.Therefore it has certain limitation as a kind of electrical maintenance instrument commonly used.

The purpose of this utility model provides the swift electron flatiron that a kind of fast fast thawing soldering connects, energy consumption is low, style is light, heat-transfer effect is good.

The purpose of this utility model is achieved in that a kind of swift electron flatiron, and it comprises electronic transformer, solder horn in power line, the insulated handle; Electronic transformer is connected to form by freq-variable electronic circuit, high frequency transformer, and to be power line be connected with electronic transformer in the insulated handle its primary structure, and the outer solder horn of electronic transformer and insulated handle is connected.

Because the utility model adopts electronic transformer, convert the 220V power-frequency voltage to high frequency low-voltage, big electric current efficiently, and convert heat energy apace to by two kinds of different ordinary metallic materials of thermal resistance, heat-transfer effect is good, the fast thawing soldering connects soon, has characteristics such as energy consumption is low, style is light, practicality again.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment of the present utility model is: it comprises electronic transformer, solder horn in power line, the insulated handle.Electronic transformer is connected to form by freq-variable electronic circuit, high frequency transformer, it is characterized in that power line is connected with electronic transformer in the insulated handle, and the outer solder horn of electronic transformer and insulated handle is connected.Electronic transformer is transformed into direct current with the 220V civil power by bridge rectifier, trigger frequency conversion output circuit self-vibration frequency conversion output by the vibration start-up circuit again, and be converted to the high frequency low-voltage and high-current and offer solder horn by high frequency (20 kilo hertzs), the high voltage of high frequency transformer after with frequency conversion, realize that electric heating changes fast.

Figure is circuit theory diagrams of the present utility model.

In the drawings, 220V exchanges through the D1-D4 bridge rectifier, and DC voltage is through vibration start-up circuit R ₂, C ₁, D ₅Qi Zhen triggers by C ₂, C ₃, L ₁～L ₃, Q ₁, Q ₂The higher-order of oscillation output circuit vibration frequency conversion output of forming, Q during beginning ₂Cut-off state is worked as C ₁Charge to D ₅During the turnover current potential, D ₅The turnover conducting, voltage adds to Q ₂Base stage, Q ₂Conducting, C ₄Through L ₄, L ₈, Q ₂Charging, and C ₅Then through this loop discharge.Because L ₁～L ₅Be same transformer, and L ₃With L ₂Phase place is opposite, at Q ₂After the conducting, L ₂Back-emf makes Q ₂Automatically shut down.Again because L ₃With L ₁Phase place is identical, at Q ₂When turn-offing, Q ₁The conducting that is triggered, at this moment, C ₄Through Q ₁, L ₃, L ₄Discharge, C ₅Then through the charging of this loop, because L at this moment ₃The electric current that is flow through makes L ₁, L ₂Produce one positive one anti-two electromotive forces simultaneously, from and make Q ₁Turn-off Q ₂Conducting simultaneously so goes round and begins again, and makes the elementary L of high frequency transformer ₄Obtain the high frequency electric of an alternation, thereby make its secondary L ₅On induce a high frequency low-voltage, it is solder horn that big electric current offers load (H), realizes that electric heating changes fast.
