A kind of soldering tin bar, as depicted in figs. 1 and 2, the column tin bar main body 1 including extrusion forming, the section of tin bar main body 1
Trapezoidal, each seamed edge of tin bar main body 1 is in arc transition.1 outer wall of tin bar main body is coated with antioxidation coating 6, sets on antioxidation coating 6
It is equipped with the graduation mark 7 along 1 length direction of tin bar main body.Setting helps core wire 2 in the middle part of tin bar main body 1, helps core wire 2 and tin bar main body
It is also set up between 1 outer wall and helps weldering portion 3.
As shown in Fig. 2, helping weldering portion 3 includes that layer 32 is helped to help welding rod 31 with several.It helps welding rod 31 to be evenly distributed on and helps weldering
2 periphery of core.Help layer 32 section be in coaxial trapezoidal of tin bar main body 1, help layer 32 to be arranged and helping welding rod 31 and tin bar master
Between body 1.It helps layer 32 and the setting of welding rod 31 is helped to improve scaling powder and 1 premixing effect of metal tin bar main body, melt in tin bar
During change, tin bar main body 1 and weldering portion 3 is helped to melt respectively, the scaling powder of liquid metal tin and liquid is uniformly mixed, and is prevented
Because liquid soldering flux quantity causes greatly liquid metal tin to be difficult to be mutually mixed with liquid scaling powder, liquid metal tin splashes, and causes
The short circuit of circuit board, to improve scolding tin quality.
As shown in Figure 1, the two sidewalls that 1 length direction of tin bar main body is parallel to each other are respectively roof 11 and bottom wall 12.Roof
11 middle parts offer the first groove 111, and the length of the first groove 111 is greater than 3/4ths of 11 length of roof, the first groove 111
Bottom wall 12 offer locating slot 112.The information such as model and the size of tin bar can be printed in first groove 111, mistake is avoided to take
It uses, and by identification printing in 111 slot bottom of the first groove, it is possible to reduce the abrasion of printing mark in transportational process.While the
The setting of one groove 111 also help inside help core wire 2(referring to fig. 2), help welding rod 31(referring to fig. 2) and help layer 32(referring to
Fig. 2) the release of internal pressure prevents the splatter generated in welding process.The setting of locating slot 112 facilitates determining for printing mark
The generation of 1 inconsistent phenomenon of tin bar main body in printing process is reduced in position.
As shown in Figure 1, one end of 11 length direction of roof offers the second groove 113, it is recessed that the second groove 113 is located at first
The outside of slot 111.The setting of second groove 113 is for positioning tin bar main body, so that tin bar main body 1 is in punching press or extruding
It is more stable in forming process, it not will cause the movement of tin bar main body 1.
As shown in Figure 1, the two sides being connected on 1 length direction of tin bar main body with roof 11 offer wave-shaped trench 4 respectively.
The wave crest of wave-shaped trench 4 is equal to trough, and wave crest and trough are in arc transition.The setting of wave-shaped trench 4 is conducive to stress
Release reduces metal tin bar main body 1 and bursts apart in course of dissolution the generation of phenomenon, while being also used to reduce tin bar in welding process
The generation of main body welding slag splash phenomena；The wave crest and trough of arc transition, so that the periphery of tin bar main body 1 is smooth.
As shown in Figures 2 and 3, it is vertically fixedly connected with several convex blocks 41 in 4 trough of wave-shaped trench, is offered on wave crest
The card slot 42 being adapted to convex block 41.The height of convex block 41 is not higher than the height of 4 wave crest of wave-shaped trench.In tin bar mass production mistake
Cheng Zhong, the tin bar completed the process need to pile up together, and the setting of convex block 41 and card slot 42 improves the company between adjacent tin bar
Compactness is connect, the stability of tin bar stacking is improved.
As shown in Figure 1, packed since traditional tin bar is typically successively placed in carton, using in this way
When be inconvenient to take, therefore one end of 1 length direction of tin bar main body offer clamping slot 5, facilitate clip to the folder of tin bar
Take, so facilitate tin bar from carton in take out.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
