Universal fiber optic connector

Abstract

The present invention relates to a general-purpose optical fiber connector, which includes a heat-melt connector assembly, a heat-shrinkable sleeve, and a heat-shrinkable sleeve protective shell, wherein the heat-melt connector assembly further includes a heat The main body of the fusion head and the ceramic ferrule, the ceramic ferrule press seat and the pre-embedded optical fiber pierced in the main body of the thermal fusion head; the tail of the heat shrinkable sleeve protective shell is connected with an optical fiber locking device for locking the optical fiber , the locking device is set separately from the protective shell of the heat-shrinkable sleeve. The invention can be compatible with optical fibers of different sizes, enhances the tensile performance of the optical fiber connector, and the heat-shrinkable sleeve protective shell can be mass-produced by using the same mold, without the need for separate production for each model, thereby improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of optical fiber connection, in particular to a general-purpose optical fiber connector for thermal fusion splicing. Background technique [0002] The fiber optic direct to the home (Fiber To The Home, FTTH) technology connects the optical cable to the general household, and can provide various information including broadcasting and communication. This technology can be applied to apartments, houses, etc. The FTTH system is connected into the home and its ends are provided in the form of fiber optic connectors. At this time, FTTH workers consider the connection between optical cables, set the length of the optical cable to several meters longer than the measured length, and then introduce it into the home. And cut the required length of optical fiber cable in the home at the construction site, assemble the optical fiber connector at the end, connect it to the optical adapter and install it in the home.

AI Technical Summary

Problems solved by technology

When clamping a square optical fiber (for example, a leather cable), because the optical fiber buckle often cannot be snugly clamped to the two opposite sides of the square optical fiber, this will cause the spliced ​​optical fiber to rotate as the nut is tightened. Tight operation and rotation, resulting in damage to the connection quality of the connection point, or even the failure of the connector;

[0005] 2. Due to the different sizes and thicknesses of the spliced ​​optical fibers, the existing optical fiber connectors need to produce various types of products to be suitable for certain specifications of optical fibers; or, although they can be applied to various optical fibers, the tensile performance is far from Does not meet the desired effect

[0006] 3. Since there are many types of optical fiber connectors, each type of optical fiber connector has its own corresponding protective cover according to the structure and size of the thermal fusion head, so the protective cover is not compatible. When a type of optical fiber connector is protected After the cover is damaged, you can only replace the same type of protective cover, or discard it, so you can't save materials, and there is a problem of wasting materials
