Optical fiber protective shell capable of being used outdoors

Abstract

The invention discloses an optical fiber protective shell capable of being used outdoors. The optical fiber protective shell comprises a bottom box and a top cover matched with the bottom box, wherein a first groove and a second groove are respectively formed in two ends of the bottom box; a raised cavity is formed in the middle of the bottom box; a first coiling fiber box is arranged at one end, which is positioned inside the bottom box, of the first groove; a second coiling fiber box is arranged at one end, which is positioned inside the bottom box, of the second groove; a first optical fiber channel is formed at the outlet of the first coiling fiber box; a second optical fiber channel is formed at the outlet of the second coiling fiber box; a third coiling fiber box and a fourth coiling fiber box are respectively arranged at extension ends of the first optical fiber channel and the second optical fiber channel. According to the optical fiber protective shell disclosed by the invention, the problem existing in the prior art that the optical fiber protection device cannot adapt to a severe environment is solved, and the optical fiber protective shell capable of being used outdoors provided by the invention can achieve excellent sealing property during application, can prevent water and moisture and effectively reduce man-made damage in a place with intensive human activity.

Description

technical field [0001] The invention relates to an optical fiber protection device, in particular to an optical fiber protection shell which can be used outdoors. Background technique [0002] The optical fiber protection device, also known as the optical cable protection device, belongs to the mechanical pressure sealing joint system, and is a connection end protection device that provides optical, sealing and mechanical strength continuity between adjacent optical cables. It is mainly suitable for straight-through and branch connections of overhead, pipeline, direct buried and other laying methods of optical cables of various structures. As a commonly used splicing end protection device at present, the optical fiber protection device has been widely used. The existing optical fiber protection device is generally composed of two half-boxes, a sealing ring is arranged between them, and an optical cable inlet or outlet hole is arranged at the end. In order to achieve sealing...
