Rotary adapter

Abstract

The invention relates to a device used for centralized converting connection of machine rooms and machine cabinets of China Telecom, China Unicom and China Mobile, in particular to a rotary adapter. The rotary adapter comprises ceramic sleeve tubes, a left shell and a right shell, wherein a first groove, a second groove, a first arc-shaped surface and a second arc-shaped surface are arranged on two corresponding corners on the top of the left shell, a first protrusion line and a second protrusion line are respectively arranged on the other two corresponding corners on the top of the left shell, a left channel for placing a ceramic sleeve tube is arranged in the middle of the left shelve tube, a third groove and a fourth groove are respectively arranged on two corresponding corners on the bottom of the right shell, a third protrusion line, a fourth protrusion line, a third arc-shaped surface and a fourth arc-shaped surface are arranged on the other corresponding corners on the bottom of the right shell, and a right channel for placing a ceramic sleeve tube is arranged in the middle of the right shell. The rotary adapter is low in cost, easy to assemble, convenient to dismantle, and capable of saving labor, reducing the working time, improving production efficiency and increasing reliability and strength of extension.

Description

technical field [0001] The invention relates to a centralized conversion and connection device for computer rooms and cabinets of China Mobile, China Unicom and China Telecom, in particular to a rotary adapter. Background technique [0002] Fiber optic adapters are also called fiber optic connectors, which are the central connection parts of fiber optic active connectors. The optical fibers are connected by the adapter through its internal open sleeve to ensure the highest connection performance between fiber optic jumpers. Fiber optic adapters are divided into SC adapters, FC adapters, and ST adapters. Among them, SC in the SC adapter stands for Standard Connector. The SC adapter is a standard square joint, made of engineering plastics, which has the advantages of high temperature resistance and not easy to oxidize. [0003] However, the existing SC adapters in China can only complete the connection and assembly of SC adapter precision ceramic or copper sleeves, adapter s...

AI Technical Summary

Problems solved by technology

[0003] However, the existing SC adapters in China can only complete the connection and assembly of SC adapter precision ceramic or copper sleeves, adapter shells and inner sleeves through complex processes such as tooling and fixtures or welding. This assembly process makes the quality of SC adapters unstable. There is a waste of manpower and man-hours, and this kind of SC adapter has many spare parts, which increases the mold opening cost of spare parts. At the same time, once the assembly is completed, the problem of disassembly cannot be solved
