Connector tail accessories and its anti-dropping parts

Abstract

The invention relates to a tail accessory of a connector and a drop-proof member thereof. The tail accessory comprises a sleeve of which the axis extends along a front-and-back direction and an extruding nut which is used for being screwed on the sleeve. The drop-proof member is assembled at the rear end of the sleeve in a drop-proof mode. The drop-proof member comprises a drop-proof member body which is rotatably matched with the extruding nut. The internal circumferential surface or the external circumferential surface of the extruding nut is provided with a nut position-limiting boss. The drop-proof member body comprises a nut matching segment which is used for stretching into the internal hole of the extruding nut or being arranged at the periphery of the extruding nut. The nut matching segment is provided with a drop-proof member position-limiting boss which is arranged at the rear side of the nut position-limiting boss and used for being matched with the nut position-limiting boss in a position-limiting way so as to limit backward moving limit of the extruding nut. The invention provides the drop-proof member capable of preventing lost of the extruding nut after the extruding nut is separated from the sleeve and the tail accessory using the drop-proof member.

Description

Technical field [0001] The invention relates to a tail attachment of a connector and an anti-dropping part thereof. Background technique [0002] The existing connector includes a connector body and a tail attachment provided at the rear end of the connector body. The structure of the tail attachment is CN104216069A and the application name is "sealing attachment for optical fiber connector and optical fiber connector using the sealing attachment" The disclosed sealing accessory is a tail accessory. The sealing component includes a sleeve whose axis extends in the front-to-rear direction. A compression nut is screwed on the rear end of the sleeve, and a sealing ring is arranged in the sleeve on the front side of the compression nut. When in use, the squeeze nut is rotated, the squeeze nut squeezes the sealing ring, and then the seal between the sealing ring and the wire and the sleeve is realized. The problem with the existing tail attachment is: between the squeeze nut and the s...

AI Technical Summary

Problems solved by technology

When in use, the nut is rotated and squeezed, and the nut squeezes the sealing ring, thereby realizing the sealing between the sealing ring and the wire and the sleeve. The existing problem with this tail attachment is: Only through threaded connection without other forms of connection, when the squeeze nut is freely unscrewed, the squeeze nut can be detached from the sleeve, which leads to problems due to excessive tightening of the squeeze nut when making lines on site or in the production workshop. If it is small or the operator does not pay attention, the squeeze nut is easy to be separated from the sleeve and lost during the loosening process, resulting in the inability to complete the production line and subsequent production assembly. This problem is particularly prominent in the high-altitude environment. In order to avoid the loss of tightening nuts, it will seriously affect the production efficiency of workers
