Connector tail accessory and adhering sleeve

Abstract

The invention provides a connector tail accessory and an adhering sleeve. The connector tail accessory comprises a combining sleeve which is internally provided with an adhering sleeve which is used for being connected with an outdoor optical cable. The tail part of the combining sleeve is provided with a throat structure and a locking member which is used for enabling the throat structure to radially contract. The rear end of the adhering sleeve is provided with an extension segment which backwardly extends to the throat structure and is used for being matched with the throat structure in a radial direction in an extruding way. The extension segment is internally provided with a channel used for insertion of the outdoor optical cable along a front-and-back direction. The throat structure is enabled to radially contract to be extruded on the extension segment of the adhering sleeve by the locking member in use so that a certain distance is reserved between the rear end of the adhering sleeve and the combining sleeve even a plug and a socket are plugged, the adhering sleeve and the combining sleeve are also maintained to be relatively fixed under the effect of friction force generated by extruding the extension segment via the throat structure, the outdoor optical cable does not backwardly move and the socket and the plug are not separated when the outdoor optical cable is backwardly pulled, and thus connection reliability is guaranteed.

Description

technical field [0001] The invention relates to the field of optics, in particular to a connector tail attachment and an adhesive sleeve. Background technique [0002] Optical cable connectors play a very important role in the process of optical signal transmission, especially the optical cable connectors used to connect external optical cables and internal optical cables are widely used in network entry projects. The Chinese invention patent with the authorized announcement number CN100573213C and the authorized announcement date of December 23, 2009 discloses an external optical cable connector, which includes a plug with contacts and a tail attachment. The tail attachment includes a sealing sleeve that is a locking nut, a combination The sealing sleeve and the bonding sleeve, the sealing sleeve is set on the outside of the coupling sleeve, the tail of the sealing sleeve and the coupling sleeve are provided with a shrinking structure, and the outdoor optical cable extends ...
