Abstract

The utility model discloses a kind of LED lamp holder special welding tin silk; including tin silk body; the tin silk body sets gradually as tin coating, anti-oxidation oxidant layer, scaling powder layer and protective layer from inside to outside; and the front end of tin silk body is provided with connection end; the anti-oxidation oxidant layer is aluminium coated; and the thickness of anti-oxidation oxidant layer is 0.3 μm to 1.5 μm, the thickness of the protective layer is 0.5 μm.The utility model novel in structural design, metal level melting temperature from inside to outside is gradually reduced, good with multiple welding processability, weld strength is preferable, and antioxygenic property is good, process Green is environment friendly and pollution-free, and solderability is good, bullet rosin will not be splashed during scolding tin, and in line rosin be evenly distributed, continuity it is good, solder horn scum silica frost is few, during automatic routing tin silk will not tangle, spiral is neat, attractive in appearance, surface-brightening, and no foul smell, smog are few.

Description

A kind of LED lamp holder special welding tin silk

Technical field

The utility model is related to tin silk technical field, specially a kind of LED lamp holder special welding tin silk.

Background technology

In LED lamp holder encapsulating structure, often occur the situation of multilayer encapsulation, multilayer, repeatedly is taken in multilayer encapsulation requirement Welding can be only achieved requirement, it is this need multiple welding in the case of, solder joint have to bear to be repeated several times heating and It is indeformable.Common solder stick welding, when welding is repeated several times, the solder joint being previously welded repeats to heat, and easily collapses The bad phenomenons such as sunken, cracking, cause welding to fail, and common solder stick surface oxidation-resistant ability, easy oxidation deterioration, shadow Ring welding quality and intensity.

Utility model content

The purpose of this utility model is to provide a kind of LED lamp holder special welding tin silk, to solve in above-mentioned background technology The problem of proposition.

To achieve the above object, the utility model provides following technical scheme：A kind of LED lamp holder special welding tin silk, bag Include tin silk body, tin silk body sets gradually as tin coating, anti-oxidation oxidant layer, scaling powder layer and protective layer from inside to outside, And the front end of tin silk body is provided with connection end, the anti-oxidation oxidant layer is aluminium coated, and the thickness of anti-oxidation oxidant layer is 0.3 μm To 1.5 μm, the thickness of the protective layer is 0.5 μm.

It is preferred that, a diameter of 0.3mm to 0.9mm of the tin silk body.

It is preferred that, the shape of cross section of the tin silk body is circle.

It is preferred that, the scaling powder layer is colophony layer.

Compared with prior art, the beneficial effects of the utility model are：The utility model novel in structural design, from inside to outside Metal level melting temperature gradually reduce, good with multiple welding processability, preferably, and antioxygenic property is good for weld strength, Process Green is environment friendly and pollution-free, and solderability is good, and bullet rosin will not be splashed during scolding tin, and rosin is evenly distributed, even in line Continuous property is good, and solder horn scum silica frost is few, and tin silk will not tangle during automatic routing, and spiral is neat, attractive in appearance, surface-brightening, no foul smell, cigarette Mist is few.

Brief description of the drawings

Fig. 1 is the utility model structural representation；

Fig. 2 is top view of the present utility model.

In figure：1 connection end, 2 tin silk body, 3 tin coatings, 4 anti-oxidation oxidant layer, 5 scaling powders layer, 6 protective layers.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of LED lamp holder special welding tin silk, including tin Silk body 2, tin silk body 2 sets gradually as tin coating 3, anti-oxidation oxidant layer 4, scaling powder layer 5 and protective layer 6 from inside to outside, and The front end of tin silk body 2 is provided with connection end 1, and anti-oxidation oxidant layer 4 is aluminium coated, and the thickness of anti-oxidation oxidant layer 4 for 0.3 μm extremely 1.5 μm, the thickness of protective layer 6 is 0.5 μm, a diameter of 0.3mm to 0.9mm of tin silk body 2, the tin silk body 2 it is transversal Face is shaped as circle, and scaling powder layer 5 is colophony layer.

Operation principle：In LED lamp holder electronic welding, tin silk body 2 coordinates with electric iron, and electric iron provides stable continue Fusing heat, solder stick is added in the surface and gap of LED lamp holder using the metal as filler, fixed electronic component into For the main component of welding, the composition of solder stick is inseparable with the quality of solder stick, will have influence on the chemical property of solder stick With mechanical performance and physical property, and metal level melting temperature from inside to outside gradually reduces, with multiple welding processability Good, weld strength is preferable, and antioxygenic property is good, and process Green is environment friendly and pollution-free, and solderability is good, will not during scolding tin Splash bullet rosin, and in line rosin be evenly distributed, continuity it is good.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
