[0002] In daily life, LED display screens can be seen everywhere. Simply put, the display screen includes a box body and a light board installed on the box body. In the prior art, there are usually three ways to connect the light board and the box body. First, the light board and the box body are fastened together by screws and other fasteners; second, the light board and the box body are connected by snaps; third, the light board and the box body are magnetically connected. Specifically, a magnet is provided on the box body, and a welding iron block that cooperates with the magnet is welded on the light board. Among them, the first connection method and the second connection method both have the disadvantage of being inconvenient for disassembly and maintenance of the light board. Although the third connection method can make the light board easy to disassemble and maintain, when the welding iron block is welded to the light board, since the welding iron block has no exhaust structure, the welding iron block is easily pushed up. Therefore, the installation quality of the welding iron block on the light board cannot be guaranteed. Utility Model Content

In other words, the support ring frame 13 is arranged around the positioning column 12 .

[0042] In order to facilitate the processing and manufacturing of the welding iron block 1, in this embodiment, the positioning column 12, the base 11 and the support ring frame 13 are an integrated structure formed by integral processing. In other embodiments, the positioning column 12 and the base 11 can be a split structure, and similarly, the base 11 and the support ring frame 13 can be a split structure.

[0043] It should be noted that the support ring frame 13 can be a polygonal frame, a circular ring, an elliptical ring, or other special shapes.

[0044] In other embodiments, the number of the exhaust port 132 may be one, but preferably the number of the exhaust port 132 is multiple, and in this case, optionally, the multiple exhaust ports 132 are evenly arranged. As a further optimization, preferably the exhaust port 132 is connected to the welding surface 131, so that a gap is formed in the welding surface 131, and accordingly, the pad 22 on the body 2 can be provided with a clearance zone corresponding to the gap. In this case, when the number of the exhaust port 132 is multiple, the conductive circuit on the body 2 can pass through the clearance zone and the area where the pad 22 is located, thereby facilitating the layout of the conductive circuit on the body 2.
