Embodiment Construction
[0030] Examples of sealing accessories for optical fiber connectors, such as Figure 2-11 As shown, the sealing accessories for optical fiber connectors include optical contacts 11, tight sleeve optical fibers 12, sleeves 13, adhesive sleeves 14, sealing rubber rings 15, anti-rotation sleeves 16, squeeze nuts 17, protection springs 18, locking Nut 19, main optical cable 20.
[0031] The optical contact 11 is assembled on the front end of the tight-buffered optical fiber 12, and when in use, the optical contact 11 is loaded into a corresponding optical fiber connector. The tight-buffered optical fiber 12 connects the main optical cable 20 and the optical contact 11 together. The optical contact 11, the tight-buffered optical fiber 12, the main optical cable 20 and their connection methods are all in the prior art, and will not be repeated here.
[0032] The front end of the sleeve 13 is provided with a thread for connecting with the housing of the corresponding optical fiber c...

The invention relates to the field of optical connectors, and in particular relates to a sealing accessory for an optical fiber connector and the optical fiber connector using the sealing accessory. The sealing accessory for the optical fiber connector comprises a bonding sleeve, a sleeve and a lock nut, wherein the front end of the sleeve is provided with a thread for being in threaded connection with the shell of the optical connector, the inner wall surface of the sleeve is provided with a stop edge for stopping the bonding sleeve moving backwards, the rear end of the bonding sleeve is provided with a rotation stop section which backwards passes through the stop edge in the sleeve, a rotation preventing sleeve matched with the rotation stop section of the bonding sleeve and a lock sleeve at the same time for stopping rotation is arranged between the lock nut and the sleeve. As the rotation stop section of the bonding sleeve, and the rotation preventing sleeve is arranged between the lock nut and the sleeve, when the sealing accessory is installed to the corresponding optical fiber connector, the rotation preventing sleeve can prevent the bonding sleeve and the sleeve from rotating relatively, and thereby the optical fiber is prevented from being damaged by twisting, and the problem that the existing connector accessory is inconvenient to install is solved.
Description
technical field [0001] The invention relates to the field of optical connectors, in particular to a sealing accessory for an optical fiber connector and an optical fiber connector using the sealing accessory. Background technique [0002] With the continuous development of optoelectronic technology, optical fiber has been widely used in communication and other fields. With the continuous expansion of the application range of optical fibers, in order to adapt to different use environments, optical fiber connectors, which are the main components of optical fiber connections, are also developing towards diversification. Outdoor multi-core optical fiber connector is one of many optical fiber connectors. [0003] Usually, the tensile and sealing functions of optical fiber connectors are realized by corresponding connector accessories. The structure of common connector accessories is as follows: figure 1 As shown, it includes an optical fiber contact 1 , a tight-buffered optica...
