Problems solved by technology

The traditional optical cable splice box only fixes ordinary optical cables, and cannot fix non-metallic reinforced core optical cables or the fixation does not meet industry standards. Fixing non-metallic reinforced core optical cables with traditional optical cable splice boxes will cause non-metallic reinforced cores to break, so that the cable tension is not enough

Embodiment Construction

[0031] The structures involved in the present invention or the technical terms used are further described below. These descriptions are only used as examples to illustrate how the present invention is implemented, and do not constitute any limitation to the present invention.

[0032] like figure 1 and 2 As shown, the optical cable splice box includes a box body 1, and a fastening device 2 is provided inside the box body 1. The fastening device 2 includes an upper pressing plate 201 and a lower pressing plate 202. The upper pressing plate 201 and the lower pressing plate 202 are closed to form a non-metallic reinforcement. The core 4 is fitted with the through hole 203, and the inner surface of the through hole is a friction surface. The non-metallic reinforcing core 4 passes through the through hole, and generates frictional force by contacting the inner surface of the through hole. At the same time, the upper pressing plate 201 and the lower pressing plate 202 exert a cert...

Abstract

The invention discloses an optical cable joint box. The optical cable joint box includes a box body, wherein the box body is internally provided with a fastening device, the fastening device includesan upper pressure plate and a lower pressure plate, the upper pressure plate and the lower pressure plate are folded to form a through hole matched with a non-metal reinforcement core, and an inner surface of the through hole is a friction surface. The optical cable joint box is advantaged in that the non-metal reinforcement core is fixed by the fastening device in a mechanical mode, fracture of the non-metal reinforcement core is avoided, firm fixing is realized, and an optical cable is prevented from being pulled off.

Description

technical field [0001] The invention relates to the technical field of optical cable splice closures, more specifically, it relates to optical cable splice closures. Background technique [0002] The following background art is provided to help the reader understand the present invention and is not to be admitted as prior art. [0003] Optical cable splice box is a popular form of optical cable splicing box, also known as optical cable splicing package, optical cable splicing package and gun barrel, which belongs to the mechanical pressure sealing joint system and is a connection 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. [0004] The strengthening core in ordinary optical cables is a metal strengthening core, such as steel, which is c...
