A joint box for elastic sleeve optical cable

Abstract

The invention relates to a splice box for an elastic sleeve optical cable, comprising a lower casing and an upper casing, the bottom surface of the lower casing is respectively provided with a cable inlet hole and a cable outlet hole, and a base is arranged on the lower casing. A disc retention plate is arranged above the base, one side of the disc retention plate is a disc retention guide area, and the other side is a branch lead-out area, and a stepped annular guide groove is arranged above the branch lead-out area, and the disc retention plate Two raised round tables are set above and below the guide area. The structure of the present invention is reasonable and simple, adopts a single plate to retain the board, and makes full use of the front and back sides to carry out functional partitions, so that the overall size control is reasonable, the protection performance and reliability are high, space is saved, it is convenient for deployment and management, and it is flexible to use and lay; The use of the buckle structure improves the construction efficiency of the casing coil, avoids the problem that the casing is easy to loose and leak in the traditional coil, makes the splitting and coil positioning of the optical fiber cable more reliable; and also improves the construction efficiency.

Description

technical field [0001] The invention relates to a splice box for an elastic sleeve optical cable, belonging to the technical field of optical cable branch connection equipment. Background technique [0002] The splice box is a very widely used equipment in the construction and laying of optical cables. With the continuous increase of the types of optical cables and the continuous improvement of construction requirements, the structure of the splice box has become more and more, and the function has also been greatly improved. In general, the development of splice boxes has evolved from generality to customization. For some special cable types, their special mechanical properties must be considered during the construction of connection, coiling, branching, etc. For example, the fiber optic bundle branch cable that is used more at present, its sleeve is made of flame-retardant flexible or elastic materials. The diameter of the casing is small, usually about 1 mm, and the num...
