Abstract
The utility model relates to a double power electric soldering iron, the temperature of which can be controlled in the periods of welding and intermitting. The utility model can be used for control the power conversion of circuits (switch resistors, capacitors, diodes, controlled silicon, etc.) by that the positions of holding and putting of the soldering iron are changed or a microswitch is lifted and pressed by a finger, which causes the optimum temperature to be obtained in the period of welding and the proper cooling to be obtained in the period of intermitting, and the effect of superior welding can be achieved. Because the average temperatures of an electric soldering bit and an electric soldering core are lower from 100 DEG to 150 DEG of the existing soldering iron, the service life of the electric soldering bit and the electric soldering core can be extended twice. The utility model also has a plurality of new functions, such as an integral support frame, a power switch, the regulation of double delta value, the indication of double color LED, and the performances, such as high safety and reliability, energy-saving, easy use, etc., of the soldering iron are improved.
Description
The utility model belongs to the electric iron that the circuit welding is used.
Now domestic and international flatiron no matter is operated in the welding phase or the welding intermittent phase all provides same power heating iron core, and flatiron use the phase of welding often short, the intermittent time is very long, cause the temperature rise of solder horn, core too high, produce: 1. unloaded high temperature makes the oxidation of soldering tip blackout, intermittent phase is long slightly, and the molten tin of residue becomes scruff, Xi Ci on the end face.2. use to occur the red copper head soon and permeated and form pin hole, pothole, effectively dipping in little grade of tin reduction of area influences welding quality.Service time one long, solder horn all attenuates and shortens, the heat conduction is obstructed, be cause solder horn, iron core is burnt to death.
The purpose of this utility model provides a kind of pair of self controllable suitable cooling flatiron of power intermittent phase, welding phase temperature is also self controllable, make it both have good welding performance, avoided unloaded high temperature of intermittent phase that solder horn, iron core are ablated again, thus the dual natural long-life that solder horn, iron core are got.
Series connection one two-way controllable silicon in the utility model flatiron heater element power supply circuits for achieving the above object, the silicon controlled trigger end is provided with the control circuit of the microswitch conversion angle of flow, the control power output.Make iron core intermittent phase, welding phase power difference, 300,350 ℃ of flatiron end face temperature low values and 450 ℃, 500 ℃ realizations of high value.
Its technical scheme is: two kinds of new handle arrangement microswitches are adjustable from attached bracing frame and the two controls of component formation work thereof.
(1) table top change lever type is set up an integrated cross-brace frame (19), 2-3cm that frame is high in handle front end bottom., there are A, B, three palms of C pin the end, about 2.5cm between AB, BC, and equal energy of AB bipod and BC bipod and two of handle tail end formation are vertical slightly different, flatiron are inclined upwardly in desktop, up to the face of shelving of 5-8cm.Get and the downward flatiron of placing for ease of holding, the handle middle part (flatiron center of gravity district) of getting flatiron of being in one's hands changes the lonely face in the garden, both sides of former handle garden cylindricality into approximate downward two tangent planes (tangent plane spacing 2.2cm, the about 2cm of area * 0.8cm) (20).Homonymy at handle middle lower portion bracing frame, device one no self-locking, have the DPDT microswitch (3) of interlock lever, when flatiron was shelved in the intermittent phase, use the AB bipod, the lever control end surmounted the placement flatiron plane that bracing frame and handle tail are constituted, thereby by desktop to pushing away (flatiron handle rear portion deadweight sagging) on the lever forward terminal, make the microswitch action change circuit supply power duty.The placement direction of rotary solding iron (selecting bracing frame BC bipod for use), microswitch is in be failure to actuate to flatiron output power circuit.Being provided with one in the handle middle upper portion has self-locking microswitch (11), but with pointing switch flatiron power supply.In the handle upper front end one dual-colored LED pipe (8) is arranged, in order to show two kinds of output power states.At handle middle lower portion microswitch rear two little openings are arranged, in adorn two miniature adjustable potentiometers (12), (14) are heightened Δ T value and are hanged down Δ T value in order to give.(2) the manual conversion hysteria of handle it change not exist together with table top and only be: will not have the miniature double-point double-throw switch of self-locking, interlock lever in the handle middle lower portion, change to having self-locking, miniature the lifting of no lever to press down switch (3), hold to point when putting flatiron or work and can lift, press down the switch snapper at random.When this type soldering iron was shelved, bracing frame was single support direction.
The utility model control circuit is by controllable silicon (2), double-colored indication LED (8), diac (9), potentiometer (12) (14), and microswitch (3) compositions such as (11) is welded on 0.8 * 7cm circuit board, and device is at handle inner hollow place.
Owing to take such scheme, flatiron welding phase to remain on high value district.After flatiron was finished once welding, the self controllable or manual low value district that changes over to made the two power controlled intermittent phase coolings of this flatiron.
Put nimblely for above-mentioned two type soldering irons being held take, put, novel soldering iron has one section structure of shaking hands in handle middle part center of gravity portion, changes part garden cambered surface into two tangent planes.Long approximately 2-2.5cm is wide by 0.5-1cm) for tangent plane.
Drawing explanation: 3. pairs of power switch of Fig. 1 control circuit schematic diagram 1. indicator lamp sample resistances, 2. controllable silicon SCR, 4. current-limiting resistances, 5. diodes, 6. current-limiting resistances, 7. diodes, 8. dual-colored LED pipes, 9. diacs, 10. coupling capacitances, 11. power switches, 12. high Δ T values are adjusted 13. high Δ T value resistance 14. low Δ T values and are adjusted 15. and hang down Δ T value resistance 16. iron core Fig. 2. appearance structure schematic diagram 17. solder horns 18. be with flatiron core retainer plate Tong 19. bracing frames 20. to shake hands to iron element version 22. handle Fig. 1 be control circuit schematic diagram Fig. 3 to the interior electricity of 21. handles; The structure of shaking hands 21. tangent planes
The utility model is described in further detail below in conjunction with circuit diagram and embodiment:
When novel soldering iron uses, turn on the power switch (11) flatiron is picked up from desktop, the 220V power supply is through K
2 2, (3) potentiometer W
1(12), high Δ T value is adjusted R
3(13), diac G (9), reach SCR (2) trigger electrode, make and to draw silicon SCR (2) conducting, provide flatiron high-power level.Meanwhile, sample resistance R (1) upper reaches overload electric current obtains instructed voltage, microswitch K
