Tail accessory for optical fiber connector, optical fiber connector and optical cable assembly

Abstract

The invention relates to an optical fiber connector, especially relates to a tail accessory for the optical fiber connector, and provides the tail accessory for the optical fiber connector, the optical fiber connector and an optical cable assembly. Wherein the tail accessory includes a sleeve, the rear part of the sleeve is provided with an adhesive sleeve for lead-out optical cables to pass through and to bond and fix, the rear end of the adhesive sleeve is provided with a plugging body, the plugging body is provided with two or more optical cable pass-through holes used for optical cables topass through, the tail end of the tail accessory is fixedly provided with anti-bending sleeves for each of the optical cables to pass through, and the anti-bending sleeves are used for avoiding overbending of the optical cables. The scheme can achieve simultaneous piercing of more than two optical cables, so that optical cables with thin diameter can be utilized, the minimum bending radius can bereduced, occupation of a bending space can be saved, a deconcentrator can be omitted, and the cost can be reduced. At the same time, since more than two optical cables are simultaneously disposed onthe adhesive sleeve, rotation of a single optical cable does not form rotational moment on the entire adhesive sleeve, and an optical fiber inside a sleeve pipe is prevented from being twisted.

Description

technical field [0001] The present invention relates to optical fiber connectors, in particular to tail accessories for optical fiber connectors. Background technique [0002] As an important structural part in the optical fiber connector, the tail attachment plays the role of sealing and cable protection in the optical fiber connector. Its overall structure directly affects the operability and maintainability of the optical fiber connector in the optical transmission system. Existing optical fiber connectors, such as the Chinese patent with the authorized announcement number CN 104216069 B, disclose sealing accessories for optical fiber connectors and optical fiber connectors using the sealing accessories, wherein the sealing accessories are tail accessories, including sleeves, arranged behind the sleeves The adhesive sleeve on the part and the lock nut are threadedly connected to the rear end of the sleeve. The front end of the sleeve is provided with a thread for threaded...
