Description

Communication line lightning protection device

Technical Field

The utility model relates to a communication cable technical field specifically is a communication line lightning protection device.

Background

A communications cable is a cable that transmits telephone, telegraph, facsimile documents, television and radio programs, data and other electrical signals. Is formed by twisting more than one pair of mutually insulated wires. Compared with an overhead open wire, the communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less influence of natural conditions and external interference and the like.

The cable outside generally all is equipped with the protective sheath, but the cable often need buckle in the use, and the time is long, and outer protective sheath breaks easily, makes cable life shorten, has the potential safety hazard moreover, and the cable receives the thunderbolt very easy break down in addition, consequently needs design a section have the lightning protection function and resistant communication cable device of buckling.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a communication line lightning protection device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a communication line lightning protection device comprising: the protective sheath, wire and protecting strip, be equipped with the lightning protection housing in the protective sheath, be equipped with a plurality of wires in the lightning protection housing, the wire outside is equipped with the wire protective sheath, the protecting strip includes interior protecting strip and outer protecting strip, a plurality of interior protecting strips are filled to the space between lightning protection housing and the wire protective sheath, outer protecting strip is equipped with a plurality ofly, is on a parallel with the protective sheath and walks the line direction setting to use the protective sheath axis to distribute as central annular at the protective sheath surface simultaneously with protective sheath fixed connection, be equipped with the scale sign on the lateral wall of the protective sheath outside, the scale sign uses the protective sheath initiating terminal to set up a scale sign as one section distance of originated zero interval, and near scale sign is equipped with two-dimensional code sign.

As a further aspect of the present invention: the content of the character mark is the distance from the starting zero point to the scale mark corresponding to the character mark.

As a further aspect of the present invention: the two-dimensional code identification content comprises related information of the communication line.

As a further aspect of the present invention: the number of the outer protective strips is four, and the outer surface of the protective sleeve is annularly and uniformly distributed.

As a further aspect of the present invention: the inner protective strip and the outer protective strip are made of elastic insulating rubber.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides the high anti ability of buckling of communication line can effectively avoid the protective sheath because buckle the transition and impaired, has improved the life of communication line, has reduced the loss strength of communication line, still has the lightning protection effect simultaneously to the cable surface is equipped with the relevant information of cable, makes things convenient for maintenance personal to maintain.
