[0002] Existing modular industrial control devices are usually installed with multiple electronic modules. Two adjacent electronic modules are connected through contacts located on the side walls. This patch-type connection uses single-sided contact and has poor vibration and impact resistance. It is often used in milliampere signal scenarios, has relatively weak flow capacity, and has high requirements for the precision of the housing and parts. As a result, the electronic modules have poor stability, weak flow capacity, and high manufacturing costs.

[0003] Furthermore, when installing the electronic module into a modular industrial control device, operators must connect a light guide to the light-emitting element. This allows the light guide to transmit light from the element to the decorative mask, creating a light display and allowing operators to easily monitor the operating status of the control device. Because the light guide is a separate component, manual assembly is required, increasing costs and significantly impacting assembly efficiency. Summary of the Invention
