Abstract

The utility model provides a tin soldering bit for quick welding electronic device. The front part of the head is provided with a slot cavity which can contain solder tin, and the end part can be connected as integration with an electric iron and a gas soldering iron. The soldering tin in the slot cavity is in a molten status when heating in order to simultaneously soldering dismount each feet of a multi-feet electronic component, so the soldering dismount time is shortened, and the damage to copper foils and elements of a printed circuit board is reduced. The utility model can be made into serial products with different dimensions according to the types of the soldering dismount elements, which is an ideal tool for producing maintenance electric apparatus.

Description

Tin soldering bit for quick welding electronic device

The utility model is that a kind of tin soaks formula quick welding electronic component solder horn, belongs to hardware ﹠ tools.

At maintenance electrical equipment, integrated circuit block is torn in weldering open, triode, resistance, during electronic components such as electric capacity, all be to weld respectively by pin to tear open in the past, for absorbing the scolding tin on the solder joint, the existing electric soldering bit device that can absorb scolding tin of prior art is as " a kind of electric soldering bit device that suction tin function is arranged " (86202461) of Chinese patent bulletin, " the special-purpose serial electric soldering bit of integrated circuit " (86210320), " inhale soldering and connect dual-purpose solder horn " (87208866), " the special-purpose electric soldering bit of dismounting integrated package " (882103288) and " multiway element disassembled welding electric soldering iron head " (902114093).But in use, or electronic component need weld respectively and tears open by pin, and efficient is low, otherwise since the multiway weldering when tearing open the heat conduction irregular, cause individual elements pin underheat or undue heat, and cause printed circuit tinfoil paper and damage of elements.

The purpose of this utility model is to have overcome above-mentioned weak point, provides a kind of tin to soak formula quick welding electronic component solder horn.

The utility model is realized with following technical scheme: by the vallecular cavity formula head of containing scolding tin be the Cylinder afterbody and form.The cylinder afterbody can be the hollow cylinder with hole, garden, is applicable to inner heating type electric iron, also can be solid, is applicable to the external-heat electric iron, and the utility model also is suitable for the flatiron of other different heat sources, as the gas heating iron etc.

Now in conjunction with the accompanying drawings the utility model is described in further details.

Fig. 1 is the single rectangle vallecular cavity of a utility model front view.

Fig. 2 is the single rectangle vallecular cavity of a utility model vertical view.

Fig. 3 is the single rectangle vallecular cavity of a utility model left view.

Fig. 4 is the single rectangle vallecular cavity of a utility model A-A profile.

Fig. 5 is the utility model rectangle vallecular cavity arranged side by side front view.

Fig. 6 is the utility model rectangle vallecular cavity arranged side by side vertical view.

Fig. 7 is the utility model rectangle vallecular cavity arranged side by side left view.

Fig. 8 is the utility model rectangle vallecular cavity arranged side by side B-B profile.

Fig. 1～4 are the solder horn of one of embodiment of the present utility model, be to have the vallecular cavity of containing scolding tin 4 by Cylinder afterbody 2 and head 3 to constitute, its tail end vertically is drilled with hole, garden 5, and have vertical sulculus 1 in both sides, be applicable to inner heating type electric iron, afterbody can be a Cylinder also, is applicable to the external-heat electric iron, above-described hollow or solid Cylinder all is applicable to the flatiron of other different heat sources, as the flatiron with the gas heating; Its head vallecular cavity can be a rectangle, also can be that the rectangle arranged side by side 6 shown in Fig. 5～8 constitutes; Or the curved rectangle vallecular cavity of profile constitutes.

Flatiron head vallecular cavity of the present utility model can be torn the type of element according to weldering open, makes the series of products of dissimilar sizes.

The utility model volume is little, and the heat conduction is even, and firing rate is fast, because the scolding tin in its head vallecular cavity is in molten condition all the time when heating, to tear element speeds open fast so weld, the efficient height, also having reduced the damage to printed circuit board (PCB) Copper Foil and element, is the ideal tools of producing maintenance electrical equipment.

Claims

1, a kind of tin soaks formula quick welding electronic component solder horn, its afterbody 2 is a Cylinder, and tail end vertically is drilled with hole, garden 5, and has vertical sulculus 1 (internal heat type) in both sides, afterbody 2 or be Cylinder (external-heat), the front end that it is characterized in that head 3 have a vallecular cavity 4 of containing molten tin.

2, tin as claimed in claim 1 soaks formula quick welding electronic component solder horn, it is characterized in that the vallecular cavity of its head 3 front ends can be by a rectangle, also can be by an arcuation rectangle, or constitute by two rectangles arranged side by side 6.
