Abstract
The utility model relates to the technical field of metal material, especially a welding strip with tin, which solves the technical problems such as unreasonable design existed in the prior art. The welding strip with tin comprises a strip body extending longitudinally, the strip body includes a copper strip having a rectangular cross section, characterized in that the copper strip is provided with a tin coating with even thickness on the periphery, the thickness of the tin coating is 28 to 32 micrometers, and the ratio of the thickness of the tin coating to the thickness of the copper strip is 1:1 to 1:2. Compared with the prior art, the welding strip with tin has the advantages of reasonable design, simple structure, stable combination of copper and tin, excellent solderability, high tensile strength, and elongation and resistivity fully satisfying the needs of engineering application.
Description
Technical field
The utility model relates to the metal material technical field, especially relates to a kind of band soldering band.
Background technology
The welding quality is distinguished from many aspects, mainly is that several respects such as solderability, tensile strength, elongation, resistivity are come comprehensive examination and evaluation.Tin-coated copper is meant that the surface is coated with the copper of skim metallic tin, as tinned wird.Tin forms tin dioxide thin film in air, prevent further oxidation.Tin and halogen also can form the film of similar effect, thereby have both had good corrosion resistance, and certain intensity and hardness are arranged again, and good moldability is easily welding again, and the tin layer is nonpoisonous and tasteless, can prevent that iron from melting into packed article, and surface-brightening.
Chinese patent literature discloses a kind of diffuse reflection type tin-coated welding strip [application number: CN201020111326.9], and what comprise that copper strips and surface thereof have is coated with the tin layer; Wherein, describedly be coated with the hole shape body that the tin laminar surface has distribution.The hole shape body on this tin-coated welding strip surface has guaranteed that not only the product physical index is stable, but also can produce diffuse reflection to sunlight, causes sunlight more to reflex on the cell panel, has improved to receive the energy of sunlight and the power consumption of solar panel.Tin-coated copper of the prior art has improved performance to a certain extent, but it is reasonable inadequately still to exist structure, is difficult to satisfy engineering and uses required problem.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, helps improving the band soldering band of welding quality
For achieving the above object, the utility model has adopted following technical proposal: this band soldering band, the belt body that comprises longitudinal extension, described belt body comprises the copper strips that cross section is rectangular, it is characterized in that, described copper strips periphery is provided with the uniform tin coating of thickness, and the thickness of described tin coating is the 28-32 micron, and the ratio of the thickness of the thickness of tin coating and copper strips is 1: 1-1: 2.
In above-mentioned band soldering band, the thickness of described tin coating is 30 microns.
In above-mentioned band soldering band, the surfacing of described tin coating.
Compared with prior art, the advantage of this band soldering band is: reasonable in design, simple in structure, the combination of copper and tin is firm, and solderability is good, the tensile strength height, and elongation and resistivity all can fully satisfy engineering and use required.

Fig. 2 is the application state figure that the utility model provides.
Among the figure, belt body 1, copper strips 11, tin coating 12, first plate body 21, second plate body 22, weld part 3.
Embodiment
As shown in Figure 1, this band soldering band comprises the belt body 1 of longitudinal extension, and described belt body 1 comprises the rectangular copper strips of cross section 11.Copper strips 11 peripheries are provided with the uniform tin coating 12 of thickness, and the thickness of described tin coating 12 is the 28-32 micron, and the ratio of the thickness of the thickness of tin coating 12 and copper strips 11 is 1: 1-1: 2.The surfacing of tin coating 12.In the present embodiment, the thickness of tin coating 12 is 30 microns.
As shown in Figure 2, between first plate body 21 and second plate body 22, be provided with weld part 3.This weld part 3 is formed by band soldering band.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as belt body 1, copper strips 11, tin coating 12, first plate body 21, second plate body 22, weld part 3 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
