Light coupling tube with hollowed-out groove

Abstract

This utility model relates to the field of optocoupler tube technology, and more particularly to an optocoupler tube with a hollowed-out groove. By opening a hollowed-out groove on the top of the tube body, operators can directly observe the laser markings containing information such as model and batch number on the top surface of the optocoupler through the groove. Combined with the limiting component to stably fix the optocoupler, it achieves rapid visual inspection of the markings while ensuring that the optocoupler does not shake. This avoids the risk of damage caused by repeated handling, such as pin bending or the package hitting the tube wall. The bottom clearance groove separately accommodates the pins on both sides of the optocoupler, preventing the pins from being deformed by pressure. The Z-shaped sidewall design of the boss provides elastic buffering capacity, which not only adapts to the dimensional tolerances of the optocoupler package, but also alleviates external squeezing and impact during transportation, preventing rigid contact damage to the internal chip of the optocoupler. This solves the technical problem that currently, when inspecting the markings containing product information on the optocoupler located inside the optocoupler tube, it is necessary to remove the optocoupler from the tube, which is quite cumbersome.
