Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application. Also, in the case of an incapable, the features of the embodiments and embodiments in the present application can be combined with each other.

[0020] In one embodiment, a field fiber optic rapid connector that is excavatized from the cream is proposed in one embodiment. figure 1 with figure 2 As shown, including the fiber bond member 20 and the ferrule assembly 10 that is embedded therein. Among them, the fiber optic joint 20 specifically includes a joining body 21, a V groove cover 22, and a mechanical lock member 23. The joining body 21 has a first end 211, a second end 213, and a V groov...

Abstract

The invention relates to a matching paste-free on-site optical fiber quick connector and a connection method. An optical fiber joint piece and an insertion core assembly pre-embedded in the optical fiber joint piece are connected with an on-site rubber-covered wire optical cable, and a first optical fiber of the insertion core assembly has an end face subjected to surface pretreatment. The connection method comprises the following steps of: S1, carrying out surface pretreatment on the end surface of the first optical fiber of the insertion core assembly, and then pre-embedding the first optical fiber in the first end of the optical fiber connector; and / or S2, performing surface treatment on the end face of a second optical fiber of the rubber-covered wire optical cable on site, and then guiding the second end of the optical fiber joint piece to be butted with the first optical fiber of the insertion core assembly. According to the matching paste-free on-site optical fiber quick connector and the connection method, the pre-embedded optical fiber and the on-site optical fiber can be in butt joint for optical signal transmission under the condition of no matching paste, and the purpose of completing optical fiber cold connection without the optical fiber matching paste is achieved.

Description

Technical field [0001] The present application relates to a fiber optic mechanical connection device, and more particularly to a field fiber fast connector and a connection method of exclaimer. Background technique [0002] The development of ftth (fiber to the home, fiber optic) extends the fiber to the user terminal, and the 5G project is being launched, and a large number of field connectors have begun to use. Most of the live fast connectors currently used are embedded. The internal fiber mismatch cream is used internally in order to reduce the Fresnel reflection generated due to low refractive index between the fiber end faces. Since the fiber matching paste is much, performance is unstable, it is easy to invalid in a temperature of temperature or humidity, and the matching cream will still adversely affect the connection performance of the fiber. Inventive content [0003] The technical problem to be solved in this application is that the above-mentioned defects of the pri...
