On-line flexible switching box of optical fiber composite overhead ground wire

Abstract

The invention relates to an on-line flexible splice box for an optical fiber composite overhead ground wire. The optical fiber in an optical unit is butted with high intensity and identical length; an optical unit protecting tube (2) is tightly matched and fixedly connected with an optical unit matching metal tube (3) sleeved outside the optical unit protecting tube (2); a metal pre-twisted wire (4) is twisted outside the optical unit matching metal tube (3); an outer layer twisted wire (5) is reversely twisted on the outer layer of the metal pre-twisted wire (4); anti-strand loosing and locking cover nuts (6) cover the two ends of the outer layer twisted wire (5), and the fixed connection is the close fit between the outer layer twisted wire (5) and the cover nuts (6). The on-line flexible splice box of the invention is widely used as the splicing device for the optical fiber composite overhead ground wire, and has the advantages that the on-line flexible splice box can not be limited by the length of a distribution disk and a splicing position, splicing can be performed in any position of the optical fiber composite overhead ground wire cable, the optical fiber is not easy to be stolen and damaged, the resources are greatly saved, and the construction intensity and the construction cost are reduced.

Description

Technical field [0001] The invention relates to a splicing box for the connection facility of the optical fiber composite overhead ground wire, which is used for the flexible connection at any position of the optical fiber composite overhead ground wire with the structure of a central tube light unit and a single-layer twisted wire structure, that is, the connection of the optical fiber composite overhead ground wire In-line flexible splice box. Background technique [0002] Optical fiber composite overhead ground wire is an overhead ground wire containing optical fiber. The connection of optical fiber composite overhead ground wire is mainly connected by three parts: optical performance, mechanical performance and electrical performance. The traditional optical fiber composite overhead ground wire junction box only has the function of optical performance connection, so it must be installed on the tower, and the electrical connection of the optical fiber composite overhead g...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing optical fiber composite overhead ground wire connection box, which is only limited to connection on the pole and tower, it needs a special matching plate and length design, the excess length is large, a lot of resources are wasted, and the connection box installed on the pole and tower is easy to be damaged and stolen. , the present invention provides an online flexible splicing box for optical fiber composite overhead ground wires, so that it is not limited by the length of the distribution plate and the connection position, simplifies the design of the distribution plate, saves a lot of resources, reduces the construction intensity and reduces the construction cost
