Optical Fiber Adapter

Abstract

An optical fiber adapter has a body divided into two accommodation rooms by a partition wall. Two ends of the accommodation room have a first opening and a second opening. Side walls and the partitionwall of the body have opposite inner surfaces. A thickened component adjacent to the first opening is formed on the inner surface. An axial guiding portion and a first stopper are formed on the thickened component. A slot is formed on a bottom wall of the body. A second stopper is disposed on the bottom wall in front of the slot. A shutter positioning slot is disposed on a top wall of the body tofix upper movable shutters. Insert slots are formed on a fixing seat to fix lower movable shutters. The fixing seat covers the slot. This optical fiber adapter has shading, dustproof and water-repellent effects.

Description

technical field [0001] The invention relates to a variety of optical fiber adapters, in particular to an optical fiber adapter with a light-shielding member. Background technique [0002] In recent years, optical fiber has been widely used as a signal transmission medium. If two optical fibers are to be connected together, optical fiber connectors and optical fiber adapters can be used to achieve this. Optical fiber connectors are usually arranged at both ends of the optical fiber and can be inserted into openings of the optical fiber adapter. The optical fiber adapter has two openings, and each opening is connected with an optical fiber connector. In order to transmit the signal to a longer distance, the energy coupled to the optical fiber is greatly increased. Among them, when the high-intensity infrared beam is emitted from one end of the optical fiber, if the user's eyes are accidentally exposed to the beam, it will often cause permanent damage to vision.

AI Technical Summary

Problems solved by technology

When the high-intensity infrared beam is emitted from one end of the optical fiber, if the user's eyes are accidentally exposed to the beam, it will often cause permanent damage to vision.

[0003] U.S. Patent No. 7,785,018 discloses a fiber optic adapter with a movable shutter, wherein when the optical fiber connector is docked with the optical fiber adapter, the ferrule of the optical fiber connector will not directly contact the movable shutter. Although it has a dust-shielding effect, it does not With a light-transmitting structure, it is impossible for human eyes to observe whether the optical path of the optical fiber is smooth

[0004] U.S. Patent No. 9,618,715 discloses a fiber optic adapter with a light-shielding element, in which the light-shielding element is returned to its original position by using the elastic restoring force of the spring. Due to the limitation of the space for the spring, the light-shielding element is pressed against the sleeve of the inner housing, and the optical fiber The space between the opening of the adapter and the light-shielding piece is not sealed by the light-shielding piece, so the effect of dustproof and splash-proof is not good
