An LC type short tail no heat shrinkable tube optical fiber active connector

Abstract

The invention relates to an optical fiber connecting device, in particular to an LC-type short-tail heat-shrink-tube-free optical fiber moving connector which comprises an inserting core, a connecting member, a spring, a tail sleeve, a shell, an optical cable bare fiber and a pressing-connecting ring. The head end of the connecting member is connected with the shell, the tail end of the connecting member is connected with the tail sleeve, the shell and the connecting member form a cavity, the spring and the inserting core are disposed in the cavity, one end of the optical cable bare fiber is fixed to the inserting core while the other end of the same penetrates the cavity, a riveting-pressing member is arranged at the tail end of the connecting member, the pressing-connecting ring is arranged on the riveting-pressing member at the tail end of the connecting member, the tail sleeve is sleeved outside the pressing-connecting ring, the tail sleeve is in the shape of a hollow cylinder, and the outer surface of one end of the tail sleeve shrinks inwards. The LC-type short-tail heat-shrink-tube-free optical fiber moving connector is simple in structure, small in occupied space and convenient to mount and use, and shedding can be effectively prevented.

Description

technical field [0001] The invention relates to an optical fiber connection device, in particular to an LC-type short-tailed optical fiber active connector without a heat-shrinkable tube. Background technique [0002] Optical fiber connector is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And minimize the impact on the system due to its intervention in the optical link. In some specific environments, such as limited space, or environments with high integration of optical fiber distribution cabinets and small wiring space, using ordinary LC-type optical fiber active connectors may cause the ODF cabinet door to be unable to be closed and too long. The tail pipe squeezes the optical fiber to increase the loss and other problems. Chinese patent ZL20...

AI Technical Summary

Problems solved by technology

[0003] Spring, the spring sleeve is set on the inner sheath of the optical fiber, the rear end of the front housing and the front end of the rear housing are socketed, and the socket of the front housing and the rear housing is provided with an accommodating area, and the inner sheath of the optical fiber is slidingly set in the accommodating area by the elastic force of the spring In the area, the inner sheath of the optical fiber protrudes from the front end of the front housing in the accommodation area. Its structure is complex, the manufacturing cost is high, it is easy to fall off, and it is inconvenient to install and use.
