Movable optical fiber connector with improved structure

Abstract

The invention discloses a movable optical fiber connector with an improved structure, belonging to the technical field of connectors. The movable optical fiber connector comprises a base, wherein a left V-shaped groove, a middle V-shaped groove and a right V-shaped groove are sequentially fixed on the base and used for accommodating reference measured optical fibers; three concave-shaped plates connected with a pressing plate through an axle are also fixed on the base, and a thread hole on the pressing plate, a puddlability adjusting spring in a groove of the pressing plate and a block below the spring are connected together through screws; the groove of the pressing plate is positioned above the V-shaped grooves; the optical fibers are tightly pressed by the lower end surface of the pressing block, a front positioning pin and a back positioning pin screwed on the thread holes on the front and back end surfaces of the base are used for regulating the travel of the pressing plate, and the front positioning pin and the back positioning pin are positioned at the front side and the back side of the pressing plate. The movable optical fiber connector is characterized in that extending parts of the base lines of the left V-shaped groove and right V-shaped groove and the base line of the middle V-shaped groove are crossed with each other to form an included angle beta; and the base lines of the left V-shaped groove and right V-shaped groove and the base line of the middle V-shaped groove are in the same plane, therefore, the optical fiber connector has the characteristics of satisfying rapid connection, having long service life and easy maintenance, and more reliably fixing the measured optical fiber.

Description

technical field

[0001] The invention relates to an optical connection device, in particular to an active optical fiber connector with improved structure. Background technique

[0002] With the development of high-speed broadband communication technology, the application of optical fiber transmission is becoming more and more extensive. Therefore, the demand for optical fibers and optical cables continues to rise. , it is necessary to test the optical performance of each optical fiber in the optical cable; the connection required in the test is a fast active connection. Chinese patent ZL200720146424.4 discloses an active optical fiber connector, which is very suitable for factory testing and other active connections. However, unfortunately, the V-shaped grooves on both sides of this fiber optic connector and the corresponding pressing blocks are placed horizontally, and the optical cable to be tested is often not easy to fix. When the optical cable slips slightly, the tested ...
