Abstract

The invention discloses and a kind ofly can welding can inhale the solder horn of tin again, be applicable to various in, on the electric iron of external-heat, it is made up of a netted copper wire and a red copper crust of thin red copper bar outside hard-pressed bale multilayer.The solder horn duty of this new construction depends on solder horn stanniferous degree of saturation, and when unsaturated, solder horn is in inhales the tin state, and when saturated, solder horn is in welded condition.

Description

Soldering iron bit

The present invention relates to a kind of soldering iron bit, particularly a kind of can be contained in common in, on the external-heat electric iron, just can weld, inhale the soldering iron bit of two functions of tin.

Present electric iron mainly is by solder horn, resistance wire heat-generating pipe and handle are formed, solder horn is inserted in and is called the external-heat electric iron in the resistance wire heat-generating pipe, solder horn is enclosed within the resistance wire heat-generating pipe and is called inner heating type electric iron outward, the electric iron of selling on the market is nothing but these two kinds of forms, their solder horn all is to make with red copper bar, can only play the welding effect, does not possess the tin of suction function.

In today that electronic technology is maked rapid progress and developed, IC-components, particularly large scale integrated circuit have been popularized and have been used in every field.They all have several even up to a hundred metallic plugs, to weld these plugs with external circuit one by one during use, the electronic product that is applied as of IC-components reduces volume, improves reliability of products, reduces power consumption or the like and demonstrates incomparable superiority.But,, will bring very big trouble to the maintenance personal once IC-components damages, for the integrated package that damages is changed from wiring board, just need with special-purpose suction tin electric iron, pin ground of a pin blots scolding tin only, could lift down the integrated package that damages like this.At present, suction tin electric iron great majority both domestic and external are all used small vacuum pump, or pump bowl, and band is inhaled the copper bit in hole, the resistance wire heat-generating pipe is made, and their cost is than higher, and dozens of yuan is to units up to a hundred and complex structure, it is also inconvenient to operate, and is out of order easily, and solder horn is easily stifled.

Task of the present invention provides the soldering iron bit that a kind of structure is different from common solder horn fully, it is characterized in that common solid copper bit is become the solder horn that is woven into by thin copper wire, but it can be installed and used as common solder horn, except the welding function, also possesses the suction tin function that general electric iron does not have.The electric iron that adopts this soldering iron bit to make has saved complicated vavuum pump or pump bowl device, has also saved the bigger band of difficulty of processing and has inhaled the copper bit in tin hole, thereby greatly reduced the cost of electric iron, and is simple to operate.

The present invention is achieved in that soldering iron bit creates out according to the capillary siphoning physical phenomenon, metal is processed into structure with capillary siphoning phenomenon, here be around weaving into the solder horn shape thin copper wire, directly be contained on the electric iron, the energising heating adds a small amount of solder flux again, the contact solder stick, the very fast small spaces that produces when compiling at whole solder horn that is covered with was inhaled and is oozed after scolding tin was melted, and until saturated, stopped to inhale the tin process.This also is a most important characteristic of the present invention, and less than the saturation degree of solder horn, electric iron is operated in inhales the tin state, and greater than the saturation degree of solder horn, electric iron is operated in welded condition.

Now in conjunction with the accompanying drawings invention is implemented to be further described.

Fig. 1 is the longitudinal sectional view and the transverse sectional view of soldering iron bit of the present invention.

Fig. 2 is the longitudinal sectional view of internal heat type soldering iron bit of the present invention.

Fig. 3 is the cutaway view of Fig. 2 along the A-A line.

Fig. 4 is the longitudinal sectional view of external-heat soldering iron bit of the present invention.

Fig. 5 is the cutaway view of Fig. 4 along the B-B line.

At first select red copper wire for use by the different size solder horn.High-power solder horn is selected thicker red copper wire for use, and power is little selects thinner red copper wire for use.Be woven into the pipe net [3] of different-diameter again with the red copper wire of same diameter.They closely are nested together one by one, and a thin red copper bar [1] is inserted at the center, and this rod plays the reinforcement effect.Outermost one deck is wrapped red copper or stainless steel substrates [2], plays heat transfer setting effect.Make the solder horn shape with the material of this structure, be contained in and be stained with a little solder flux on the electric iron and can use.Fig. 2 Fig. 4 is embodiment, and [4] are the resistance wire heat generating member.

The present invention compares with common solder horn, improves work efficiency 2-3 doubly, and cost is low, and the life-span is long.
