A hot melt nut is embedded in the conductive hole 52 through a processing process.

[0044] like Figures 1 to 4 As shown, a mounting boss 13 is provided on the inner side wall of the box body 11, and a connecting hole 131 is provided on the mounting boss 13. A through hole 121 corresponding to the connecting hole 131 is provided on the cover plate 12, and a connecting fastener passes through the through hole 121 and is connected in the connecting hole 131, so that the cover plate 12 is fixedly covered at the opening. An M3 hot melt nut (copper alloy material) is melted into the connecting hole 131 by hot melt technology, so as to facilitate tight fixation with the fastener. The through hole 121 is a rounded through hole, and the connecting fastener is a countersunk screw.

[0045] like Figures 1 to 4 As shown, a reinforcing rib 14 is provided on the side of the cover plate 12 facing the box body 11. The provision of the reinforcing rib 14 ensures that the cover plate 12 is thin while still maintaining its toughness. A third opening is provided on the cover plate 12, and the third opening is an oblong hole for cooperating with the fifth socket portion 29, and also provides a certain protection for the fifth socket portion 29.

[0046] When the debugging box of the LED display module needs to be used, the fifth socket portion 29 is connected to the corresponding interface of the connected display (which can also be an extension line or a conversion interface), and then, under the premise of ensuring stable installation, the operation key 42 is pressed (this step is when using the battery 40; if there is no power, an external power cord can be used) to supply power to the debugging box of the entire LED display module and the LED display module 60, so that the debugging box of the entire LED display module can be used.

[0047] The debugging box of the LED display module is compatible with multiple interfaces. The operator can control the LED display module through the debugging box of the LED display module with the help of an external computer, or verify the performance of the LED display module through the debugging chip 30 (the debugging chip 30 contains tooling or other pictures or videos) or the inserted memory card (the memory card contains tooling or other pictures or videos) stored inside the debugging box of the LED display module. The performance includes optical performance and thermal performance.
