Protective structure for optical fiber connector

Abstract

The invention relates to a protection structure for an optical fiber connector, particularly relates to a structure for protecting the optical fiber connector, and aims at providing the protection structure for the optical fiber connector, which has high safety. The protection structure for the optical fiber connector comprises a protection shell (1) and a sealed tail sleeve (2), wherein a safety shell (21) is fixedly arranged on the sealed tail sleeve (2), and is of a cylinder shape; one end of the safety shell (21) is tightly fixed on the periphery of the sealed tail sleeve (2) in a trumpet shape, and the other end of the safety shell (21) extends towards the direction connecting one end of the protection shell (1); and when the sealed tail sleeve (2) is screwed on the protection shell (1), the safety shell (21) is sleeved on the protection shell (1), and one end of the protection shell (1), which is far away from the sealed tail sleeve (2), is positioned in the safety shell (21).

Description

Technical field [0001] The invention relates to an optical cable connection device, in particular to a structure for protecting an optical fiber connector. Background technique [0002] Optical fiber connectors are especially plastic connectors used indoors. When their mechanical strength, waterproof and dustproof capabilities cannot meet the requirements of use, it is usually used to install a protective shell 1'and a seal outside the connector 3' The tail sleeve 2'is reinforced. Such as figure 1 As shown, when in use, first connect the protected connector 3', then install the protective housing 1'to provide mechanical strength protection to the protected connector 3', and finally install the sealing tail sleeve 2'to the protective housing 1'on. The sealing tail sleeve 2'contains a sealing ring. First, the sealing ring is placed on the protective shell 1'between the end of the sealing tail sleeve 2'and the optical cable 4', and the inner diameter of the sealing tail sleeve 2'i...

AI Technical Summary

Problems solved by technology

[0003] However, the existing protective structures for optical fiber connectors have the following defects, such as figure 2 As shown, when the connector 3' needs to be disassembled, if the operator makes a mistake, he will first disassemble the protective shell 1', that is, move the protective shell 1' away from the connector 3', and at this time The sealing boot 2' and the optical cable 4' are still in a fastened state, and the protective housing 1' cannot retreat freely, so that the disassembly force will be transmitted to the protected connector 3' through the optical cable 4', which may cause the protected Damage to connector 3'
