Fibre-embedded optical fibre fast connector

Abstract

The invention discloses a fibre-embedded optical fibre fast connector and relates to a passive optical device for field fast-forming of an optical fibre and an optical cable. The fibre-embedded optical fibre fast connector comprises an embedded optical fibre alignment and clamping device, an optical fibre guide and optical cable clamping piece, a tail sleeve, a joint outer cover of a subscriber connector (SC) optical fibre connector and a joint end-face dust-proof cap, wherein the embedded optical fibre alignment and clamping device comprises an integrated shell, a ceramic ferrule, an embedded optical fibre, a gradually-variable diameter optical fibre guiding piece, a V-shaped slot butting integrated piece, a clamping pressure connection piece, a spring and an optical fibre clamping opening piece; the embedded optical fibre is inserted into the ceramic ferrule; the joint end-face dust-proof cap is arranged on one side of an end face of the ceramic ferrule; the other side of the ceramic ferrule is fixed at the front end of the V-shaped slot butting integrated piece; the gradually-variable diameter optical fibre guiding piece is fixed at the rear end of the V-shaped slot butting integrated piece; the V-shaped slot butting integrated piece and the gradually-variable diameter optical fibre guiding piece are fixed by the integrated shell; the optical fibre clamping opening piece issuspended and clamped at a corresponding opening of the integrated shell; and the optical fibre guide and optical cable clamping piece is in pressure connection with the integrated shell.

Description

technical field [0001] The pre-embedded optical fiber fast connector of the present invention relates to a passive optical device used for rapid on-site termination of optical fiber cables. Background technique [0002] Broadband construction has been promoted to the level of national strategy, and the scale of fiber-to-the-home construction is increasing day by day. The focus of broadband construction lies in the shift of the construction site from outdoors to indoors. The laying and termination of optical cables is an extremely important link. For the narrow indoor operating space, how to reduce the difficulty of construction is a key research topic in the industry. Traditional and expensive optical fiber fusion splicers are used. Not only is the operation difficult, but the cost of investment is huge, which does not meet the decentralization and immediacy of user activation. Optical fiber fast connectors are a necessary tool to promote the construction of fiber-to-the-h...

Problems solved by technology

The pre-embedded fiber optic quick connector has the same factory-level grinding as the optical fiber active connector on the end face of the connector, so the return loss index is reliably guaranteed, but due to the high difficulty of this technology, alignment technology and clamping technology are its core keys , How to realize the reliable docking of the imported fiber and the pre-embedded fiber, how to realize the safe clamping of the introduced fiber, the realization process is complicated, and the methods are also different. At present, there are problems such as low success rate, inconvenient operation, and the need for a variety of supporting tools. and other defects

At present, the repeatability of optical fiber quick connectors only pays attention to the repeatability of the optical fiber cable clamping parts and does not fully consider the related factors of the embedded structure, and there are defects such as low efficiency and index drop. How to use the same hundreds of millions of quick connectors? It is very important to achieve subsequent maintenance and prolong product life
