Connectors and their accessories

Abstract

The invention provides a connector and a connector accessory thereof. The connector comprises a plug, a sleeve and a tail sealing structure. The sleeve is internally provided with an adhesive sleeve. The sleeve is provided with an adhesive sleeve stop surface which is used for stopping and limiting the adhesive sleeve in a rightward direction. The connector also comprises a reducing sleeve which is connected at the left end of the sleeve and used for being connected with an adaptive socket. The adhesive sleeve is provided with an axial limiting sleeve. The axial limiting sleeve is provided with a stop matching surface which is used for being matched with the adapter sleeve in a stopping way so as to stop axial movement of the adhesive sleeve relative to the adaptive sleeve when the tail sealing structure is rotatably connected on the sleeve. According to the connector, the adhesive sleeve and the axial limiting sleeve are pressed on the adapter sleeve by the sleeve and axial movement of the adhesive sleeve and the axial limiting sleeve is ensured not to occur so that a main cable does not axially and circumferentially move under the frictional force of a tail connecting structure when the tail sealing structure is connected and use reliability of the connector can be guaranteed.

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. Common fiber optic connector accessories and connector structures are 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 sleeve. ...

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. When you continue to turn the lock nut to move to the left, it will drive the main cable to move to the left. , so that the branch optical cable located in the sleeve will be bent, causing the transmission attenuation of the optical signal, and the adhesive sleeve will move to the left with the main cable and will not fit with the adhesive sleeve stop surface of the sleeve, which will also affect the connection Tensile properties of the device
