Description

Technical Field

[0001] This utility model relates to the field of industrial automation equipment connection technology, and in particular to a quick-switch modular IO interface group. Background Technology

[0002] In fields such as industrial automation and intelligent equipment control, I / O interface groups serve as core components for signal transmission and device connection, and their performance directly impacts the overall system's operating efficiency. Currently, most traditional I / O interface groups on the market adopt an integrated structure design, with fixed interface types that cannot be flexibly replaced. According to industry statistics, over 65% of industrial equipment needs to have its I / O interface replaced due to production demand adjustments during its service life. Replacing a traditional integrated I / O interface group requires disassembling the entire equipment casing and disconnecting all circuits, with each replacement taking an average of 40-60 minutes. This not only severely impacts production progress but may also lead to circuit damage due to improper disassembly and assembly, resulting in equipment repair costs of approximately 2000-5000 RMB per instance. Furthermore, traditional I / O interface groups have simple heat dissipation structures. When continuously transmitting data at a rate of 10-20 Mbps, the temperature of core components can easily rise above 70°C, leading to decreased signal transmission stability and a data packet loss rate as high as 3%-5%, which cannot meet the requirements of high-precision equipment.

[0003] As smart devices become smaller and more multifunctional, the demands for modularity and convenience in I / O interface groups are increasing. While some existing modular I / O interface groups support interface splitting, they mostly use bolt fixing or snap-fit ​​connections for module assembly. Data shows that bolt-fixed modular I / O interface groups require specialized tools and 8-10 steps for a single module replacement, with replacement efficiency only 30% higher than traditional integrated structures. Snap-fit ​​connections, after approximately 500 insertions and removals, experience a 40% wear rate, leading to module loosening, increased interface contact resistance to 100-200mΩ, and signal transmission delay to 50-100μs. Furthermore, most modular I / O interface groups lack optimized layout for different interface types; a single module only supports 1-2 types of interfaces. When a device needs to connect to more than 3 external devices simultaneously, multiple modules must be stacked, increasing the device size by 150%-200% compared to a single module, and also causing messy wiring, signal interference, and other problems, making them unsuitable for compact device installation environments.
