Communication cable with stretching warning function

Abstract

The invention discloses a communication cable with a stretching warning function, and belongs to the technical field of cables. A pulling sensing adjustment assembly, an over-pulling driving alarm rod and a sound production warning piece are adopted; when a cable is deformed due to stretching, the air pressure in a sealing spherical shell is increased, so that the thrust applied to the over-pulling driving alarm rod is increased, the over-pulling driving alarm driving rod moves upwards, a sound production piece makes a sound due to vibration and impact on an impact block, the warning function of the sound production warning piece is triggered, related workers can know that a cable body is stretched and deformed in time, and the cable body can be effectively prevented from being further stretched. A light-reflecting observation-assisting piece is adopted, the light-reflecting observation-assisting piece has an auxiliary reminding function, so that the worker can quickly find out the stretched part after hearing the warning sound, the practicability is improved. A stretching connecting ball, the pulling sensing adjustment assembly and the like are convenient to disassemble and assemble and can be disassembled from the cable body conveniently, so that the coiling of the cable is not influenced.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically relates to a communication cable with a stretch warning function. Background technique [0002] Communication refers to the exchange and transmission of information between people or between people and nature through a certain behavior or medium. In a broad sense, it refers to the use of any method or medium by two or more parties that need information without violating their respective wishes. Accurate and secure transmission of information from one party to another. Communication cables are common utensils in communication technology. [0003] Communication cables are cables that transmit telephone calls, telegrams, fax documents, TV and radio programs, data and other electrical signals. It consists of more than one pair of mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the advantages of large communication capacit...

AI Technical Summary

Problems solved by technology

[0004] In the process of laying the communication cable, due to improper operation and other reasons, it is easy to cause the cable to be partially stretched, and the cable will be deformed to a certain extent when it is greatly stretched. The communication cable in the prior art is not stretched when it is stretched. It has a warning function, so that the relevant staff cannot detect the deformation of the cable due to stretching in time, and it is easy to cause the cable to be further stretched, resulting in damage to the cable due to excessive stretching, which will affect the transmission of signals
