AI Technical Summary

Technical Problem

In existing non-standard ferrule fiber threading and curing fixtures, the optical fiber is not fixed, making it prone to bending and breakage. Furthermore, the skewed fiber cores experience fiber shrinkage issues within the inner hole of the ceramic ferrule.

Method used

The design uses a rectangular pad board with silicone strips featuring concave grooves and fiber optic slots. Combined with a fixing mechanism, the optical fiber is limited and tightened. The end sleeve, middle sleeve, and end are constrained by the placement groove and strip groove. The optical fiber tail section is fixed using silicone strips and a pressing structure.

Benefits of technology

It effectively prevents optical fibers from bending and breaking during the curing process, ensuring that the optical fibers are straight and fixed, improving the contact connection effect between the plug and the slanted fiber core, and avoiding the impact of optical fiber movement on the contact connection.

Abstract

A fiber optic ferrule insertion and curing fixture includes a rectangular pad with an upper protrusion and multiple concave grooves. A silicone strip is fixed to the pad with screws, and an optical fiber slot is formed at the upper end of the silicone strip. The optical fiber slots correspond one-to-one with the concave grooves. The pad also has a mounting plate with an mounting strip mounted on it. The upper wall of the mounting strip has an upper protrusion with a front and rear strip groove. Multiple placement slots are formed on the upper protrusion, penetrating the front and rear walls of the upper protrusion. The placement slots are U-shaped and, through the concave grooves, limit the optical fiber and provide coarse positioning.
