Abstract

The utility model discloses a dual-purpose solder iron head for sucking tin and soldering. After dipping soldering tin fully once, a plurality of weld spots can be welded continuously. The utility model has the advantages of high efficiency, simple structure, good sucking tin performance, and obvious superiority on demounting electronic components. The structure of the solder iron head is that the head end of the soldering iron is opened with a narrow groove. The existing soldering-iron head can be processed into the utility model scarcely increasing fabricating cost.

Description

Dual-purpose solder iron head for sucking tin and soldering

The utility model relates to a kind of solder horn, is suitable for the repairing of electrical equipment and the repairing of metalware.

When existing common solder horn welds, often only can cling molten tin seldom, need dip in again again behind 1～2 point of burn-oning and get molten tin, and the difficult grasp of the size of solder joint, welding efficiency is lower.In addition, also have a class to have the flatiron (seeing Chinese patent CN85203299 for details) that send welding wire mechanism automatically.Though this class flatiron welding efficiency height, spot size are even, its cost height, complex structure.The effect of the molten tin of the absorption of above-mentioned in addition two kinds of flatirons is all not ideal enough, therefore just seems very inconvenient for dismounting electronic devices and components, particularly multiway electronic devices and components.

The purpose of this utility model provide a kind of simple in structure, cheap, welding efficiency is high, have the dual-purpose solder horn of inhaling the tin function.

The purpose of this utility model realizes as follows: utilize the capillary siphon principle, open a thin narrow groove on the solder horn top, inhale in the molten tin bath thereby easily molten tin is sucked.Inhale the shape of molten tin bath and can do the wedgewise groove, its ideal dimensions is the widest part 0.5～1mm of wedge-shaped slot, flute length 1.5～2mm.

Below, two embodiment that provide according to Figure of description specify the utility model work one, but invention is not limited to shown in the accompanying drawing.

Fig. 1 is the dual-purpose solder horn schematic diagram of inner heating type electric iron;

Fig. 2 is the dual-purpose solder horn schematic diagram of external-heat electric iron.

Fig. 1 is the dual-purpose solder horn that the solder horn of existing ordinary inner heating type electric iron makes into by above-mentioned design, and solder horn body 2 tail ends are with fastening volume 1, and the head end of solder horn body has wedge shape suction molten tin bath 3.For the inner heating type electric iron head of 40W, the ideal dimensions that wedge shape is inhaled molten tin bath is flute length 1.5mm, the wide 0.7mm of groove tail end.Fig. 2 is improved external-heat electric soldering bit, and common external-heat electric soldering bit only is that a red copper bar is made, and need not load solid volume on the solder horn, therefore only needs to open wedge shape suction molten tin bath 5 at the head end of solder horn body 4 and gets final product.When making the external-heat electric soldering bit of 20W, the more satisfactory groove tail of wedge-shaped slot is wide to be 0.5mm, and flute length is 1.5mm.

Adopt structure of the present utility model, inhale in the molten tin bath and can suck a certain amount of molten tin, but therefore dip in a plurality of solder joints of continuous welding behind the full scolding tin, so the comparable common flatiron of its welding efficiency increases, the size of solder joint is also more easily grasped. The dual-purpose solder horn of this suction tin welding is the improvement to common solder horn, and it does not increase any mechanism or other part, has only opened a narrow groove at head. So, send the flatiron of welding wire mechanism to compare with band, its low cost of manufacture, the molten tin effect of simple in structure, absorption is better. Because suction tin of the present utility model is effective, so this seems very easy, more demonstrates its superiority when the dismounting multiway electronic device especially for the electronic devices and components on the demolition circuit board.

Claims

1, a kind of solder horn that is suitable for welding of electronic devices and components circuit or dismounting is characterized in that having on the solder horn a thin groove.

2,, it is characterized in that the wedge shape that is shaped as of the thin groove opened on the solder horn by the described solder horn of claim 1.

3,, it is characterized in that the length of the wedge shape suction molten tin bath on the solder horn is 1.5～2mm, the bottom width 0.5～1mm of wedge-shaped slot by the described solder horn of claim 2.
