Description

Technical Field

[0001] This utility model relates to the technical field of detachable circuit board structures, and in particular to a detachable circuit board structure for traffic indication equipment. Background Technology

[0002] Early traffic signage systems mostly used fixed circuit boards. These circuit boards typically employed traditional circuit board designs, with components fixed by soldering, lacking ease of disassembly and making maintenance and replacement relatively difficult. To improve the convenience of equipment maintenance and upgrades, modular circuit board designs were introduced. By dividing the circuit board into multiple functional modules, fault detection and repair became more efficient. Standardized interfaces and connectors were introduced, making it easier to interchange modules. Circuit board structures at this stage began to support quick plug-and-play, improving equipment maintenance efficiency. The detachable circuit board structure used in traffic signage systems includes the circuit board body, functional modules, interfaces and connectors, and heat dissipation and protection components. However, in the current detachable circuit board structure used in traffic signage systems, the circuit board is not easy to install and fix, making it difficult to disassemble and replace after damage during use. Therefore, the above-mentioned technical problems need to be solved. Utility Model Content
