Description

Technical Field

[0001] This utility model relates to the field of industrial automation control equipment, and in particular to a compact light guide module structure. Background Technology

[0002] Currently, most control system products require dedicated light guides to output and display indicator light. For those with multiple display states, multiple sizes of light guides are needed due to the different distances at the front of the module. Installing the light guides on the main circuit board will occupy a large area, resulting in a waste of circuit board utilization. In addition, it requires a lot of mold investment, and the subsequent production and assembly time is also more.

[0003] In summary, a space-compact light guide module structure is needed to address the shortcomings of existing technologies. Utility Model Content

The light guide module adopts a stacked structure design integrating the main circuit board and the indicator light board within the module cover, and the electrical connection between the two circuit boards is achieved through a ribbon cable. This design integrates functional circuitry and indicator functions within the same compact space, significantly reducing the overall module volume and achieving efficient space utilization. Simultaneously, both the main circuit board and the indicator light board are detachably connected to the module cover, facilitating later maintenance, replacement, or upgrades, improving product maintainability and production assembly efficiency.

[0006] Optionally, a lamp panel retaining block is provided at one end of the module cover, and a lamp panel retaining hook is provided at the other end of the module cover.

[0009] Optionally, an indicator light cover is provided on the module cover. The indicator light cover is detachably connected to the module cover, and the module cover has a cover groove in which the indicator light cover is disposed. Providing a detachable indicator light cover on the module cover and embedding it into the cover groove protects the internal indicator light structure from external contamination and mechanical damage, while also ensuring a neat and aesthetically pleasing appearance. The detachable cover design facilitates the inspection or replacement of the indicator light components, improving product maintainability. Simultaneously, the cover groove structure aids in precise positioning, improving assembly accuracy.

[0010] Optionally, the module cover is provided with a snap-fit ​​groove, and the indicator light cover is provided with a snap hook, the snap hook corresponding to the snap-fit ​​groove. By providing a snap-fit ​​groove on the module cover and a snap hook on the indicator light cover, a snap-fit ​​connection structure is formed, making the cover firmly installed and easy to disassemble, allowing it to be opened without tools.
