Optical fibre connector

Abstract

An optical fiber connector consists of a base and three V-shape slots fixed on the base, which is used for containing reference optical fiber and tested optical fiber. Three concave plates with a concave surface oriented to the front head face of the base are fixed on the base, the rear part of a pressure pad is inserted into the concave positions of the concave plates, and the concave plates and the pressure pad are connected by three axes running through the right side of the concave plates. The pressure pad is provided with screwed holes, and the pressure pad, a spring, and a pressure block are connected together by bolts, the optical fiber is tightly pressed at the lower end surface of the pressure pad. A front nest pin and a back nest pin respectively screwed in the screwed holes in the front and back head faces of the base are used for adjusting the travel route of the pressure pad. The optical fiber connector is characterized by rapid connection, long service life, easy maintenance, and reliably fixing the tested optical fiber.

Description

technical field [0001] The invention relates to an optical fiber connector, in particular to an active optical fiber connector with three V-groove structures. Background technique [0002] With the increasing development of optical fiber transmission applications, for those who install, maintain, and test optical waveguide lines and inspectors of optical fiber and cable manufacturers, it is necessary to frequently connect optical fibers. Fiber optic connectors typically use metal, ceramic, rubber, or glass tubes with fine inner diameters to accommodate reference and test fibers. figure 1 It is a schematic diagram of the main part of the active optical fiber connector widely used at present to connect the optical fiber. In the figure, 2 is the above-mentioned glass tube. Let the bare optical fiber 12 extend into a certain place A in the glass tube, then the right optical fiber 3 is removed from the coating 31 in the same way, and the bare optical fiber 32 is inserted into th...

AI Technical Summary

Problems solved by technology

This type of optical fiber connector requires precise processing for the connecting tube; the optical fiber is generally very brittle, and the quartz glass optical fiber is easily broken. Once the optical fiber is broken in the tube, it is extremely difficult to take out the broken optical fiber, which often affects the connection test and even delays the construction period.

In addition, because the structure of this type of optical fiber connector is too small, usually only the glass tube can be held by hand, so it is not suitable for rapid testing, and it is not reliable for fixing the optical fiber
