Linked connecting plug of single-core optical fiber

Abstract

The invention relates to a device for concentrated switch connection of machine cabinets of machine rooms of China telecom, China mobile and Unicom, and discloses a linked connecting plug of a single-core optical fiber. The linked connecting plug comprises a tail sleeve sleeved on the optical fiber, wherein a pull handle is connected with a pressure plate; the pressure plate is connected with an inner shell of the plug; a core inserting seat is arranged inside the inner shell of the plug; a spring is sleeved at one end of the core inserting seat and is arranged inside a spring seat; the spring seat is fixed at the end part of the inner shell of the plug; one end of a middle sleeve of an adapter is connected with the core inserting seat, and the other end of the middle sleeve of the adapter is connected with an inner sleeve; the tail part of the inner sleeve penetrates into an optical fiber cable; an outer sleeve is sleeved outside the optical fiber cable; and the tail sleeve wraps the middle sleeve, the inner sleeve and the outer sleeve of the adapter. The linked connecting plug is low in cost, can be matched with the existing device, and can improve the capacity of the machine room with the same size as the like product.

Description

technical field [0001] The invention relates to a device for centralized conversion and connection of computer rooms and cabinets of telecommunications, mobile and China Unicom, and in particular to a single-core optical fiber interlocking connection plug. Background technique [0002] At present, the three major companies of China Telecom, China Mobile, and China Unicom use single-core single-adapter connection devices for signal conversion. The single-core single adapter has the disadvantage of large volume, and the cabinet with the same volume cannot expand the capacity. Foreign countries adopt products produced in Western Europe and Japan. Although they can reduce the volume, they need to use φ1.5mm ferrule. This kind of connection device is expensive and cannot match the existing domestic equipment. Contents of the invention [0003] The purpose of the present invention is to provide a single-core optical fiber interlocking connection plug, which has low cost, can be ...
