Abstract

Provided is a short protective cover for optical fiber connectors. The invention belongs to an optical fiber connector design technology, and relates to an improvement on the tail protective cover foroptical fiber connectors. The short protective cover is characterized in that a sleeve (1) has a sleeve extension section, there is a sleeve ring slot on the sleeve extension section, there is a bonding sleeve ring slot on a bonding sleeve (2), and the head of a set screw (8) enters the bonding sleeve ring slot. A sheath cylinder section sleeves the sleeve extension section. A ring boss is disposed in the sleeve ring slot. A stepped inner hole of a fastening nut (3) limits a fastening ring (7) on the rear end face of the external thread section of the sleeve (1) and inside the fastening nut (3). The invention presents an improved short protective cover for optical fiber connectors. The protective cover is shortened, and can be used in a small space. The bonding sleeve has an anti-rotationfunction, and the risk of fiber breaking during optical fiber twisting is eliminated. The effect of sealing between the inner hole f a tail sheath and an optical cable bundle is improved.

Description

technical field [0001] The invention belongs to the optical fiber connector design technology and relates to the improvement of the tail protective cover of the optical fiber connector. Background technique [0002] figure 1 It is a structural schematic diagram of a current tail protection cover. It includes a sleeve 1, a bonding sleeve 2, a fastening nut 3, a pressure sleeve 4, a sheath 5 and an optical fiber bundle 6; the rear part of the sleeve 1 has an external thread, and the internal thread at the front end of the fastening nut 3 is screwed on the sleeve On the external thread of 1, the front end of the sheath 5 is located in the inner hole of the fastening nut 3, and there is an annular positioning boss on the outer surface of the front end of the sheath 5, and the pressure sleeve 4 is located behind the annular positioning boss. The fixing nut 3 compresses the pressure sleeve 4 and the annular positioning boss on the rear end surface of the sleeve 1. The bonding s...
