Embodiment Construction

[0009] The pre-embedded optical fiber quick connection device of the present invention comprises a wheel handle and pre-embedded optical fiber. The wheel shank is mainly a ferrule with a nominal aperture. There is an opening on the ferrule, and a conical guide port is provided at one end to facilitate the insertion of the optical fiber to be connected. When it is practical, there is a matching liquid at the opening; the joint point between the optical fiber to be connected and the pre-embedded optical fiber is located at the opening of the wheel handle; the sleeve keeps the optical fiber in the tube slightly bent when locking the optical fiber to be connected, so as to ensure that the pre-embedded optical fiber and the pre-embedded optical fiber The fiber end faces remain in contact.

[0010] The device includes a wheel handle 1, pre-embedded optical fiber 2, nominal aperture ferrule 5 and sleeve 6. There is an opening 3 on the ferrule 5, which is convenient for the matching ...

Abstract

The invention relates to a quick pre-buried optical fiber connection device. The device comprises a wheel handle (1), a pre-buried optical fiber (2), a nominal aperture insertion core (5) and a bushing (6); an opening (3) is formed on the insertion core (5); a conical guide opening (4) is formed at one end of the opening (3); one end of the pre-buried optical fiber (2) is placed in the opening (3) of the insertion core (5) and butted with an optical fiber to be butted, and the other end of the pre-buried optical fiber (2) is placed on the end face of the insertion core (5) and polished to be a standby; a space retained in an inner hole of the bushing (6) is used for keeping a tiny bent state of the optical fiber to be butted and has a function of locking the optical fiber to be butted; and matching liquor (8) is prepared in the opening (3). During use, the optical fiber to be butted (7) enters the opening (3) of the insertion core (5), where the insertion core (5) and the pre-buried optical fiber (2) are butted, through the bushing (6). The connection device has a simple structure, low production cost and simple and quick operation, guarantees the butting precision of the optical fiber to be butted, effectively reduces insertion loss of joints and increases echo loss.

Description

technical field [0001] The invention relates to a pre-embedded optical fiber quick connection device, which can simply and quickly realize the alignment and connection of optical fibers at the scene where optical fiber active links are required, and belongs to the technical field of optical fiber communication device manufacturing. Background technique [0002] In the optical access network, active connectors need to be used extensively. Therefore, a fast and effective optical fiber connection device is needed to realize the connection of optical fibers. The non-embedded optical fiber connection device is inconvenient to operate and has poor flexibility in use. Most of the existing pre-embedded optical fiber connection devices require an additional alignment device with a complex structure, which increases the cost. Therefore, there is a need for an optical fiber quick connection device with simple structure, low cost, simple and fast operation, and suitable for various op...
