Problems solved by technology

The pressure of the elastically fixed outer sheath of the unclosed sleeve is mainly the elastic force of the sleeve, and the outer sheath is fixed axially against the sleeve by the fixing piece, which only presses a small circle of the outer sheath, and there is also contact The area is small, and the outer sheath is a material with very low hardness and strength. When the contact area is small and the pressure is relatively large, it is easy to break

Abstract

The invention provides a loose-sleeve optical cable field assembly connector and a fixing assembly thereof. The loose-sleeve optical cable field assembly connector comprises a locking assembly for locking a bare optical fiber and an optical fiber coating layer and the fixing assembly for fixing an optical fiber reinforcement core and an optical fiber outer protective sleeve. The locking assembly comprises an inner core, an inner core cover and a casing, and locks the bare optical fiber and the optical fiber coating layer through the modes of interference fit and radial extrusion of a pluralityof steps. The fixing assembly comprises a shell, an extrusion casing and a limiting sleeve, the limiting sleeve extrudes the extrusion casing in the axial direction, and the extrusion casing is tightly matched with the tail part of the shell to fix the reinforcement core and the optical fiber outer protective sleeve between the extrusion casing and the shell.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to a field-assembled connector for a loose sleeve optical cable and a fixing component thereof. Background technique [0002] In indoor or outdoor optical fiber distribution equipment, the jumping of optical fibers is the core issue, and these jumpings are all done through loose-buffered optical cable connectors. The difference between loose-buffered optical cables and tight-buffered optical cables lies in the fiber There is a gap between the coating layer, the cable strengthening core and the outer sheath, and they are not integrated, but the above four elements of the tight-sleeved optical cable are integrated, so the above-mentioned four elements of the tight-sleeved optical cable are integrated during the process of pulling the optical cable. The relative displacement is very small, but the above four relative displacements of the loose sleeve optical cable are very...
