Description

A kind of optical fiber quick connector with ceramic insertion core

Technical field

The utility model relates to the coupling arrangement field in optical fiber telecommunications system, particularly relates to a kind of optical fiber quick connector with ceramic insertion core.

Background technology

Optical fiber quick connector is can reusable passive device for what connect that two optical fiber or optical cable form continuous light path, use it can not need heat sealing machine at optical fiber construction scene, only by simple tool for connecting, utilize MACHINERY JOINT just can realize the direct Cheng Duan of indoor optical cable, be widely used in optical fiber transmission line, fibre distribution frame and test optical fiber instrument, in instrument, it is the optical passive component that current usage quantity is maximum, the preset fiber active linker of Assembling is called for short the preset joints of optical fibre, it installs principle: penetrate a certain length and ground optical fiber in preset joints of optical fibre head ceramic insertion core inside, the optical fiber of construction optical cable mates cream with preset optical fiber by aiming to contact and add at contact point place, due to the transparent shape of coupling cream, not easily flow, refractive index is close with optical fiber, the Fresnel reflection produced due to the air of low-refraction between fiber end face can be reduced, thus reach optical fiber and lead to light characteristic.

Along with the continuous maturation of high-precision ceramic lock pin technique of alignment, it instead of V-type slot type alignment so traditional on market gradually, carry out aligning by high-precision ceramic lock pin technique of alignment to two optical fiber to connect, effectively can reduce loss during spread fiber, and pottery has non-conductive property, cold property of not being heated, optical fiber is not subject to external force clamping when mounted, in the raw, thus ensure that the reliability that the preset joints of optical fibre use, high temperature performance is superior.

But existing optical fiber quick connector is in order to add coupling cream in the joint of two optical fiber, usually coupling cream adding trough can be offered, although facilitate the interpolation of coupling cream, but the water proofing property of connector is made obviously to decline, thus accelerate the corrosion and damage of connector and joint, shorten the serviceable life of optical fiber telecommunications system, and sunlight directly through the effect of coupling cream adding trough on the transmission fiber, is easy to cause interference to signal transmission; And in order to make optical fiber aim at connection more accurately; insert connector time its outside fiber boot divested; make the junction of optical fiber and the connector connected more fragile; the junction of optical fiber and connector is easy to be bent or pull when mounted; cause the damage of optical fiber or fracture, causing spread fiber loss to strengthen, the situation of obstructed light even can be caused to occur; thus not only cause the waste of optical fiber, also reduce joint efficiency.

Summary of the invention
