Prefabricated optical cable connector and welding-free optical fiber distribution case

Abstract

The present invention relates to a prefabricated optical cable connector and a welding-free optical fiber distribution case. The prefabricated optical cable connector comprises a prefabricated opticalcable adapter, a prefabricated optical cable plug and a prefabricated optical cable socket; the prefabricated optical cable adapter comprises a cylindrical base body with openings at two ends, radialprimary key grooves and a plurality of radial assistant key grooves are arranged at the inner sides of the two ends of the cylindrical base body at intervals in the circumference, a connection plateis fixedly arranged at the center of the inner side of the cylindrical base body, and the connection plate is provided with a radial T-shaped adaptive hole; the prefabricated optical cable plug and the prefabricated optical cable socket are the same in structure, and a P guidance needle is fixedly arranged at the front end of the high-density beam concentration optical fiber connector of the prefabricated optical cable plug; and the front end of the beam concentration optical fiber connector of the prefabricated optical cable socket is a P guidance hole matching with the P guidance needle of the beam concentration optical fiber connector of the prefabricated optical cable plug.

Description

technical field [0001] The invention relates to a prefabricated optical cable connector and a non-melting optical fiber distribution box, and relates to the technical field of optical fiber accessories. Background technique [0002] When ordinary optical cables (optical cables containing more than 2 cores of optical fibers) are laid and connected to optical fiber distribution boxes or optical fiber distribution devices, the sheath layer must be stripped one by one from the optical fibers, and the end faces of the optical fibers must be cut with a special cutter. Then put the two optical fibers that need to be fused into the left and right sides of the fusion channel of the optical fiber fusion machine on the construction site, align the end faces of the optical fibers and heat and weld them together. Multiple optical fibers need to be repeatedly fused. Perform fiber insertion loss or return loss detection one by one. If the fiber loss value is judged to be unqualified, the f...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the prior art of optical fiber fusion splicing above are that it is difficult to guarantee the quality of fusion splicing at the construction site, resulting in large optical transmission loss and poor consistency after splicing multi-core optical fibers, high repair rate of repeated splicing, heavy workload of on-site splicing, long construction period, and high splicing costs. higher

At the same time, because there is no uniform standard for the height and wiring method of the optical fiber fusion splicing distribution box, resulting in many specifications of the fusion splicing distribution box, irregular wiring, and unsightly wiring, which brings inconvenience to later operation and maintenance.
