A connector and its connector accessories

Abstract

The invention provides a connector and a connector accessory. The connector comprises a plug, a sleeve and a tail sealing structure; a bonding sleeve is arranged in the sleeve; the connector also comprises an adapter sleeve which is connected with the left end of the sleeve and is used for matching the connection of a socket; the bonding sleeve is provided with an anti-rotation sleeve; and a plugging structure is arranged between the anti-rotation sleeve and the adapter sleeve, wherein the plugging structure can prevent the relative rotation of the bonding sleeve and the adapter sleeve when the tail sealing structure is rotationally connected onto the sleeve. When the connector is used, the circumferential rotation stopping of the bonding sleeve and the adapter sleeve can be realized through the anti-rotation sleeve, the fixation of the adapter sleeve in a circumferential direction can ensure that the bonding sleeve and a main cable fixed by the bonding sleeve will not rotate circumferentially; and when the tail sealing structure is rotated, the main cable will not rotate under the rotational friction of the tail sealing structure, and therefore, a plurality of branch cables in the sleeve will not be wound and twisted with each other, and thus, when being used, the connector is more safe and reliable.

Description

technical field [0001] The invention relates to a photoelectric connection element, in particular to a connector and its accessories. Background technique [0002] With the rapid development of optoelectronic technology, the connector, as an important part of the transmission and transfer of optoelectronic signals, plays a very important role in the optoelectronic transmission system, and whether the sealing performance of the connector is good or not has a great impact on the transmission quality of optoelectronic signals. have a great impact. [0003] The sealing of general optical fiber connectors is realized by corresponding connector accessories. The structure of common fiber optic connector accessories and connectors is as follows: figure 1 As shown, it includes a plug 18, a main cable 17, a sleeve 12, an adhesive sleeve 13 and a rubber sleeve 16. The right end of the sleeve is also provided with a tail sealing structure for sealing between the main cable and the sle...

AI Technical Summary

Problems solved by technology

[0004] When this kind of optical fiber connector seals between the main cable and the sleeve through the tail sealing structure, the lock nut presses the retaining ring to deform the rubber sleeve, and the left end of the rubber sleeve radially tightens and hugs the main cable, locking There is a lot of friction between the nut and the retaining ring, between the retaining ring and the rubber sleeve, and between the rubber sleeve and the main cable. Continue to turn the locking nut to drive the rubber sleeve and the main cable to rotate together, so that Since the plug and the socket are mated and fixed, the branch optical cables separated from the main cable in the sleeve will be intertwined and twisted together. In the lightest cases, the optical performance of the connector will be reduced, and in severe cases, the optical fibers in the branch optical cables will be damaged. Twist off, inconvenient to use, easy to cause damage to the connector
