Abstract
A brazing pin for use at soldering for example a cable lug and a railway rail consists of a pressed or turned main part (11) with a stud (13) at one of its ends, a cap (14) of solder alloy material pressed on the stud and flux (15) in the space between the cap and the stud. The outer diameter of the cap (14) corresponds to the outer diameter of the main part (11), whereas its inner diameter is slightly smaller than the inner diameter of the stud (13), so that a hermetic enclosure for the flux is obtained.
Description
The present invention relates to the manufacture method of soldering pin, be used for for example the cable connector lug being soldered to rail, the present invention also relates to this soldering pin.
When for example cable connector lug and rail fuse, the so-called soldering pin of known use.This soldering pin also can be used for other connector and be used in and require the surface of metal object and any kind of is fused.When cable connector lug and rail or other metalwork are welded by soldering, the soldering pin is inserted into the medium pore of cable joint, be close to rail, subsequently heavy current by soldering pin and rail, produce a luminous arc, in the solder alloy fusing of soldering pin end, fill the hole of cable connector lug, the cable connector lug couples together by fusing and rail simultaneously.
In early known soldering pin, inserting of solder alloy is contained in of soldering pin, subsequently relatively thinner solder alloy lid be added to insert on.Put the scaling powder that correct soldering is needed in the little space between inserting and covering.
The main body of soldering pin preferably by the brass manufacturing so that can conduct electricity well.This main body can be provided with annular groove suitably, and the part of this main body before groove becomes the coupling part with solder alloy after welding, helps the hole of filling cable connector lug.
The manufacturing of this soldering pin is somewhat expensive, because the main body of the soldering pin of brass is at first wanted turning, suppresses or casts out, and scolder is inserted and must be installed on the main body of soldering pin subsequently, and again through pickling, turning and cleaning, the bonnet of gland that has scaling powder is on inserting.Except making costliness, the lid that the shortcoming of existing soldering pin has scaling powder in addition is not to cover airtightly, causes the scaling powder possibility moisture absorption, and the soldering pin can not be used.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of method and this soldering pin that simple, cheap and lid is airtight soldering pin of making is provided.
According to the invention provides a kind of method of making the soldering pin, the soldering pin is used for the cable connector lug is soldered to rail, and this method comprises the following steps: that the main body of a described soldering pin of machined makes and forms a plush copper at an end of described main body; The hollow cap that material of machined is a solder alloy, the external diameter of described lid equates that with the external diameter of described main body the internal diameter of described lid is littler than the external diameter of described plush copper; Filling scaling powder and have the lid of scaling powder to be interference fitted on the plush copper of described main body the inside in described lid.
The present invention also provides a kind of soldering pin, be used for the cable connector lug is soldered to rail, comprise a main body, a lid and a scaling powder, wherein, the end of the main body of described soldering pin is provided with one and the integrally formed plush copper of main body, described lid is a solder alloy system, and its external diameter equates with the external diameter of described main body, and internal diameter is littler than the internal diameter of described plush copper, described lid and described plush copper interference fit, described scaling powder is located in the described lid.
The soldering pin of Zhi Zaoing is very simple in this way, and is more cheap than the manufacturing of above-mentioned common soldering pin, and lid covers airtightly, because it is with thicker material manufacturing, and has the diameter slightly littler than plush copper, and therefore available interference fit.
Describe the present invention with reference to the accompanying drawings in detail, in the accompanying drawing:
Fig. 2 illustrates the schematic diagram that the part of the soldering pin of prior art is analysed and observe;
Fig. 2 shows the schematic diagram that the part of soldering pin of the present invention is analysed and observe.
Common soldering pin shown in Figure 1 for example has the main body 1 with the brass of turning or compacting.Columniform main body 1 is provided with cannelure 2, its objective is the joint-cutting that uses the soldering pin when the soldering, the passback of also restriction heat or pass to the left-hand component of main body.
The front end of main body 1 (among Fig. 1 the right) is provided with inserting on 1 of solder alloy.Be covered with thin lid 4 before 3 inserting by solder alloy system.A certain amount of scaling powder 5 is filled out in lid 4, lid 4 is covered insert on 3 subsequently.Because at the deformable sheet materials of lid in 4, lid 4 is than being easier to and inserting 3 disengagements, and be not inserting to encase gas-tightly.
The rear end of main body 1 (Fig. 1 left side) is provided with hollow handles knob 6, wherein inserts and fixed an one metal wire 7.Wire 7 is as the alive joint of soldering pin, and can be by transmitting certain energy can melt so that process is ended when heat increases.
Use the soldering pin when soldering, main body 1 fusing of the soldering pin in the right of groove 2 or the place ahead inserts 3 and cover 4 and become filler.
Correspondingly, have a main body 11 according to soldering pin of the present invention (Fig. 2), groove 12 handles knob 16 and wire 17.Corresponding parts have same effect among these parts and Fig. 1.Can certainly be with not being with soldering pin wiry.
During fabrication, main body 11 is provided with plush copper 13,11 one-tenth of this plush copper 13 and main bodys are whole, is same material, just brass material.Lid 14 is preferably colded pressing by solder alloy and is formed.Other manufacture method can be with turning or casting.The material thickness of lid 14 is greater than the thickness of the lid 4 of prior art shown in Figure 1.Lid 14 external diameter equates with the external diameter of main body 11, and covers the external diameter that 14 internal diameter is slightly smaller than plush copper 13, cover 14 and plush copper 13 between be interference fit.Size can for example be: main body and to cover 14 external diameter be 8mm, the diameter of plush copper 13 is 4.5mm, and covers 14 internal diameter and the external diameter difference of plush copper 13 is 0.05-0.15mm.Also can make the soldering pin of other size.
Before covering on the plush copper 13, in lid, add a certain amount of scaling powder 15 to lid 14.Since have above-mentioned shown in and the explanation structure, the lid 14 install on the plush copper 13 after, scaling powder adds certain overvoltage in advance.
Is the same according to the effect of soldering pin of the present invention with known soldering pin.Total difference is that soldering pin of the present invention is simpler, makes more cheaply, is that the lid 14 in unique solder alloy source can airtight mode be fixed on the plush copper 13 in design.
